PURPOSE.

This machine was designed especially for chuck-ing, drilling and ferruling wood handles used in the manu-facture of toy garden tools by the Wilkins Toy Company, Keene, N. H. The specified operations formerly required three separate handlings on different machines. The new machine, however, is entirely automatic and needs but one attendant to replenish the stock and ferrules.

The stock supplied varies in length from fourteen incbes to forty-eight incbes and in diameter from nine six-teenths of an inch to thirteen sixsix-teenths of an inch. The sticks, however, present irregularities for which allow-ance must be made. In one stated length of stock there may be a variation of two inches and some are warped out of

true by as much as one eighth of an inch to the foot. Two sizes of ferrules are used, nine sixteenths and

five-eighths inside diameter. These come in bulk while the handle stock is supplied in the form of dowel rods.

OPERATIOM.

The sticks and ferrules are dumped into their re-spective receptacles by the attendant and thereafter they are handled auto matically. _{An agitator is provided to}

start the sticks down the chute and prevent clogging.

Upon reaching the bottom of the chute the handle is

push-ed up to the head end guide plate. It now drops upon the

conveyor and is moved to the chucking position where the head end is tapered and the tail end is rounded. The chucks are automatically released after the required cut has been made in order to prevent unnecessary wear on the knife edges. The handle is advanced six inches for the operations of drilling and ferruling which are carried on simultaneously with the chucking of the next handle fol-lowing. Here it is pushed into the ferrule which is

se-cured in place by pricking the metal into the wood on two opposite sides. During the pricking operation the handle is drilled to a depth of two inches. The finished handle is now ejected from the machine.

On Plate I this complete cycle is shown graphi-cally.

The ferrules are thrown out to the periphery of a revolving disk by the action of centrifugal force and from there they descend the chute. Those that are turn-ed the wrong way are ejectturn-ed during their descent.

Features of special advantage are the few simple adjustments provided in order that the machine may handle the specified variations in length and diameter of stock.

TO accommodate different lengths, the operator slides the

adjust-ing screw. A change in diameter requires a resetting of

the upper jaws for position and an adjustment in the width of handle chute. For the other size of ferrule it is nec-essary to change the ferruling guide and the stop in the taper chuck. _{The ferrule pricker points must also be} ad-justed to the different diameter.

RESULTS OF PRELIMINARY TEST.

The official test of this machine was made be-fore any extensive run had been attempted. It was, how-ever, in perfect running order at the start as far as the original design was concerned. Since the assembling had been hurried in order to allow time for a test before this report was due, we could not be sure of the parts being

ad-justed firmly enough to hold their relative positions. The first test was an hours run for production. White birch rods were fed at the rate of twenty-two per minute. _{During this run eleven hundred and forty handles} were produced, there being some time lost in stoppage. The first stop was due to a rod catching at the base of the chute. _{The second was caused by the pusher cam} slip-ping and failing to withdraw the stick from the ferrule guide where the end was caught. _{In both instances the} at-tendant did not throw the clutch out quickly enough and the shear links in the feed chain were broken and had to

be replaced. A third stop had to be made due to the fqact

that a ferrule which was slightly over size caught in its pass1ge. All of these difficulties can be easily

recti-fied.

All of the bearings and thrust collars were ex-amined and found to be running cool.

A short power test was also made. A one

horse-power Westinghouse shunt motor was attached in the proper pulley ratio. With the machine running at the rate of twenty cycles per minute, the average input was 1134 watts. Assuming _{a motor efficiency of} 75%, the power delivered was about 1 1/3 horse-power. _{The power necessary to overcome}

the friction, that is, with the machine idle, was found to be about 7/8 horse-power.

Since the above test several thousand handles have been turned out. _{The largest number produced to date} without a stop is six hundr,d. _{The machine was tried at} a speed of twenty-five cycles per minute and ran very sat-isfactorily.

The de~lection of the hanger reaches due to the pressure of the gripper jaws was measured. The micrometer gage was applied at the upper surface of the jaw housings on both head and tail stocks. _{Both headstock housings} were deflected .008" _{and the tail-stock housing .007".}

- DESCRIPTION -Power Distribution

The main frame of this machine consists of two

leg castings secured by four reach rods. The two upper rods serve to support the head mechanism and also act as ways for the adjustable tail stock. The two lower rods are used as braces only. The counter-ohaft (A5) extends the entire length of the machine and its journal boxes have slight universal movement in order to obtain easy a-lignment. The tight and loose driven pulleys are placed at the tail end and the belt shipper rod is twenty-four

inches above the bed and within easy reach from any point around the machine. The power is transmitted to the cam

shaft (A 12) at the head end through a belt and pair of re-duction gears. A jaw clutch (A 14) engages with the can

shaft gear and is operated by a rod located four inches a-bove and parallel to the belt shipper. This clutch is al-ways _{thrown out by the belt shipper when the power is shut}

off.

The can shaft is, from necessity, supported at four places. _{This is in order that the bending effect on}

the shaft due to the pressure on the cam will not be ex-cessive. _{There are two transverse cam shafts, one at each} end, which are connected with the main cam shaft by spiral

gears. The gear and came on the longitudinal shaft at the tail end are mounted on sleeves, in their respective positions. These sleeves are keyed to the shaft and free

to move with the carriage or tail stock. This carriage is moved by a long adjusting screw and its weight is suf-ficient to hold it in position without clamping.

Feed.

The dowel rods are supported at each and by

brackets (BC50). The one at the tail end is mounted upon the carriage and does not need separate positioning. The end guides, consisting of flat plates, are made adjustable to meet special conditions which may arise. To aid the stock in dropping down the chute and to prevent clogging as much as possible, an agitator (3051) acting against the under siide of the sticks is placed at each end. These are operated simultaneously by cams located on the longitudinal shaft. It was found by experiment that a short recipro-cating motion lifting sticks slightly on the backward move-ment would lead. most readily to the required result. This action is obtained by pivoting the bearing or lifting lever to an intermediate lever which is free to swing on a fixed pivot, located underneath and parallel to the sticks.

The reciprocating motion is transmitted to the agitating lever through a toggle joint in such a way that the

trans-mitting lever causes the agitating lever to be pushed up as it is moved back, and to bear gently on its return.

At the bottom of the chute, each handle is push-ed up to the head end guide plate by a light rod operatpush-ed from the tail end chuck spindle lever in order that it will have the proper longitudinal position for ferruling. it

is next carried forward by means of two chain conveyors (3048) acting simultaneously from cams on the main shaft. Since this travel of six inches has to be accomplished in a minimum length of time, the forward motion is by spring. This arrangement will also prevent breakage, for if a stick should catch on some obstruction while in the carrier, it would simply hold back against the spring. Shear pins are provided that will give way in case the chains are held a-gainst the return stroke.

The rods are next lifted off the conveyor and

held by V-faced gripper jaws (BC34) operated from the

trans-verse cam shafts. _{These lifting jaws are self adjusting} for the varying diameters of rods and also have to hold the rods firmly enough _{for the chucking and drilling, An} in-termediate lever is provided _{and works the jaws through} compression springs. _{The cam lever acts against the} in-termediate lever through a toggle which closes when the jaws are raised, in order that too much strain from the gripping force will not be brought on the cam. At the drilling and ferruling position is a pusher (337) attached

to and a part of the head end jaws. As soon as the stick is gripped firmly the bottom jaw is actuated forward by means of a separate cam and carries with it the upper jaw which is free to slide. This movement drives the stick

into the ferrule. The upper jaws are also adjustable and

are held by the spindle hanger reaches.

Chucking.

The chuck spindle thrust levers are fitted with an automatic release which prevents the chuck knives rub-bing after the required taper has been cut. Since the handles cannot be depended upon to assume the same position

each time, the movement of the spindles cannot be definite. The cam lever has a positive motion forward which is great

enough to cut the _{maximum length of taper required of the} machine. _{This lever is connected to the spindle lever by} a latch (3Q15) which is held against a lin by a compression spring. _{This spring is adjusted to give sufficient} fric-tion between a curved projecfric-tion on the latch and the pin to carry the spindle forward until the plug, inserted in the chuck at the necessary depth, brings up against the stick. _{The latch is then forced to give way and allow} the spindle to spring back. _{In the rounding chuck, the} latch releases when the bottom of the curve is reached. This design of latch presents other good features in that the spring compression increases towards the end of the

stroke where it is not needed, and also, after the release the pressure on the pin diminishes, due to the increase in leverage. Since the pressure of the latch on the pin is

upwards there is less dragging force on the spindle due to the weight of the levers.

Drilling and Ferruling.

The drill _{spindle is actuated from the head end} transverse cam shaft. _{Its forward motion is by spring} tension in order to prevent accident from crowding the drill too hard. _{The drill spindle is drawn back a little after} two-thirds of its stroke for the purpose of relieving the chips.

The ferrules are dumped upon a revolving horizon-tal disk (D-3) driven through bevel gears by the transverse cam shaft. _{The centrifugal force is great enough to throw} the ferrules to the periphery and start them down the chute. The entrance to this chute consists of sides and top only and extends over and along the edge of the disk for a dis-tance of six inches. _{In order to prevent clogging of the} ferrules at the entrance, the 6pening is extended from the inner to the outer edge at a long angle. _{If a ferrule is} in an upright position it is simply brushed aside along the angular opening out of the way of the next ferrule follow-ing. _{As the chute leaves the ferrule receptacle it takes} a sweeping curve downward and at the bottom of the vertical

section the ferrule receives the stick and pricking opera-tions.

The ferrule has an internal flange on one side and is plain on the other, and it is necessary that this plain side should always face the handle. Consequently a ferrule ejecting device (D-12) is provided on the vertical section of the chute for removing all those which face the wrong way. This ejecting device consists of two vane wheels geared to turn in opposite directions, at the same

speed, and located on each side of and in the same plane with the chute. Each wheel has four vanes which extend through the sides to the centre of the chute and are so spaced and operated that one ferrule may pass by at each quarter revolution. _{Geared to these wheels and in a plane} with their axes is a crank shaft to which is attached a light spring rod with a downwardly extending hook on its end. _{This hook rod passes through a guide near its middle.} The action of the crank and centre guide causes the hook to pass through an opening in the front of the chute, enter the ferrule which is being lowered by the vane wheels, engage in the flange of the ferrule, and withdraw

it from the chute. _{If, however, the plain side of the} ferrule faces the front, the hook does not touch the fer-rule but allows it to pass down the chute. This mechanism

is run by a loose belt so that when the lower part of the chute is filled with ferrules the conveyor wheels are

blocked and held until free to tunn again. The ejected ferrules are dropped into a box and after accumulation are

transferred back to their receptacle.

The stick is driven into the ferrule through a guide block at the back of which are set two pins for hold-ing the ferrule in position. These blocks are removable and their sizes vary with the ferrules used. The prick-ing of the ferrules to the stick is accomplished by adjust-able pins set in two levers (D-32) pivoted directly under the chute. _{These levers are placed opposite each other} and are operated through a set of toggle levers from a pin

set in the stick agitator cam. The builder changed the design of the cam lever somewhat by making it in two parts and inserting a catch between the two. This catch is thrown into engagement only when a handle is in a ferrule and is operated by a light lever which is raised by the handle itself as it enters the ferrule. If no handle is present, the catch does not engage and the ferrule is not pricked and thereby pressed out of shape.

The ferrule is backed by a thin hardened steel plate having a hole large enough to permit the passage of the drill and the removal of the chips. Since the drill is quite long, a guide plate supporting a hardened steel bushing is provided to start the point central into the stick. _{An exhaust duct for the chips is cut between the} backing plate and the guide plate.

Exhaust tubes are run from the drill and two cutting chucks to a suction fan. The tube to the tail end is telescoped in order that it may adjust itself with the carriage movements. Hoods or guards are provided for the exposed gears.

Necessary Changes in Design after Operation.

The only alterations necessary were in the chain feed. _{It was found that the chain conveyors were given} considerable vibration during their rapid forward motion and would snap out the handles. _{To prevent this, a}

groov-ed _{support was placed under the main link to steady it.} This piece was included in one of our original sketches and is shown in our notes.

To further insure _{the rods staying in their} re-spective grooves, some strips of steel were placed three quarters of an inch above the chain between the chute and each set of gripper jaws.

EXPERIMENTAL WORK.

The nearest approach to a machine of the type under consideration which we were able to find, was a semi-automatic double saw and chuck machine with a continuous chain feed, taking one stick at a time from the operator. This design was for heavier work than we contemplated and its features did not appear to be adapted to our require-ments. _{So in view of lack of available examples and well}

tried principles, we were obliged to resort to experiments in order to acquire the special knowledge necessary to prepare ourselves for the work.

To determine the gripping force necessary to hold the sticks firmly for chucking, we made use of a hand

operated machine in which this work was previously done. The stick was placed in two cast iron V-shaped grooves, one at each end. _{Over these we set two V-shaped cast iron} blocks from which we suspended a weight board. Weights were added until the stick was held firmly during the chuck-ing. _{We used a chuck for five inch taper turning at 1800} R.eP.M. and found the necessary gripping force to be about 200 pounds. _{This test met the worst possible conditions} and so we are well on the safe side, since in our design the chuck speed is increased to 2300 R.P.M. and allowance is made for a maximum taper of three inches.

The rounding chuck which has little to do in comparison with the taper chuck, is given a speed of 1300 R.P.M.

In determining the time to be allowed for dril-ling we tried to obtain the speed of maximum efficiency

without too much heating of the drill. At 2800 R.P.M. of the drill spindle, the time required to obtain a depth of two inches was found to be three seconds. To run at high-er speeds we turned a 5 inch pulley for an electric motor, and belted it to the drill spindle. With 110 volts on

the motor, and drill speed of 3200, the time was 2 1/2 seconds. At 125 volts the drill was turning 3600 R.P.M. and the time was reduced to 2 seconds. Upon further

con-siderations, we decided that the drill could be run at a higher speod with better results and accordingly a speed of 4500 R.P.M. was adopted.

A test was then made to determine the thrust

nec-essary to run a 3 inch taper chuck upon a piece of 3/4 inch stock and by an arrangement of levers and a spring balance, this was found to require a force of 12 pounds. The thickness of shavings was approximately 1/100 of an

inch.

An experiment upon the chuck spindle release showed that about one pound was required to hold the latch upon its bearing pin when the thrust upon the latch was 12 pounds, as determined above.

By placing weights on the top of a steel prick

punch held vertically the force needed to prick a ferrule was found to be 130 pounds. This was the mean of several experiments, in all of which the angle of the prick point was 24*.

Trials were made in accordance with the

design-er's ideas of the manner of feeding rods and ferrules. A

stick chute was set up and piled full. Of the various

impulse motions tried, the most successful was a short, quick, reciprocating motion, lifting sticks slightly on back stroke. The crooked sticks were easily accommodated and did not clog.

Experiments relating to ferrule feed were made on a friction disk taken from a drill press. This disk was rotated within a sheet steel rim provided wIth a

spe-cially devised chute entrance opening at the side. Forty R.P.M. was found to be a satisfactory speed as the ferrule fed continuously and did not clog, and a large per centage were in the correct position.
