HEEL-BUILDING MAoHiNE.

Application filed January 27, 1917, Serial No. 144,883. Renewed April 2, 19 21. Serial No. 458,086

T o aZZ whom it may concern Be itlmown that I, ARTHUR S. EVEREIT, a citizen of the United States, residing at Lawrence, in the county of'Esse'X and State of Massachusetts, have invented an Improvement in Heel-Building Machines,of which the following is a specification.

- This invention relates to certain improvements in thattype of machineknown as the Page heel-building machine, ina commercial form of which the freshly-cemented lifts are assembled in a heel-form, and the heels thus formed, are then successively delivered thereby to aseries of presses connected together in the form of an endless chain, so that they are pressed together immediately after being assembled, and are held pressed together for a sufiicient time to enable the cement to set.

While the necessity of the employment of building nails is thus avoided, it has been found that building nails are desirable in' some instances, particularly where a high heel, composed of pulp, is being manufac tured; onaccount of the fact that the pulp .is not so strong as the cement which holds the lifts together, so that, when the heel is pricked'in connection with the heel-attach} ing operation, the lifts sometimes split...

n a type of said machine in which the heel is built in a form which is adapted to open, against the action of springs, to penmit the form to be withdrawn from the heel when clamped, there is a tendency to cause the lifts to slip out of position to a slight ex tent, astheyare clamp'echwhich tendency is not sufficiently resisted by said springs of the light tension which it is necessary to em ploy, so that the heel produced is not always as nearly perfect, under such conditions, as is usually desired.

An object of the invention is to provide means whereby a building nail may be driven in the heel as-soon as it'is assembled, and before it is delivered to one of the presses, above referred to, so that all the ad vantages of having immediate pressure applied to the assembled liftsare secured, and, the same time, the heel is provided with a building nail, without serious delay to the building operation, as usually performed with the machine above roferredto.

A. further object of the invention is to pro vide means whereby the heel form. may be securely locked and the heel and lifts held in desired position while the pressure'is ap plied thereto, and to provide meanswhereby the form will be automatically unlocked to permit ready withdrawal of the form from the heel, after it has been clampech ()-ther objects of my inventionare to provlde an improved form of building naildriving mechanism, which is especially adapted for use in the connection above referred to. I accomplish these objects by the means shown in' the accompanying drawings, in which only such. portions of the whole inachine are shown as relate to -the. subject mat ter of the. invention.

In the drawing, 4,- indicates a portion of the frame of the machine'in which the guideways for the endless chain of heelpresses are formed, each of said presses comprising a plate 5 in which a vertically movable rod 6 is mounted, said rod bearingan arm7, sup porting a. clamping plate 8, for clamping a heel-on the plate 5, and said rod 6 being sustained in inoperative position by: the roller 9, which is in turn supported by aver} tically movable track-section 10, normally sustained by a light spring 11- and locked. in raised position by a latch 12, mounted on a pivot 13, a strong springle being arranged to overcome the spring 1.1 and force said rod 6 downwardl to clamp a heel, when the latch 12 is disengaged from the track-sec,- I

tion 10; A horizontal table 16 is provided at the loved at which the plates 5 trav'e1,so that each plate is successively held in such a position that-a heel may be formed on the table, and slid therefrom onto the plate,

Said table 16 is provided with afipair of guideway' ribs 18, in which a heel-form is mounted to slide, said heel-form comprising a fiat base-plate 20, having a pair of arms 22 at its longitudinal edges, which extend over said table. A T-shaped bracket 24 is mounted for forward and rearward adjustment on said base-plate and a. pair of heel-engaging fingers 26 are mounted in the arms of said bracket 24L, respectively, said arms being arranged to extend divergent-1y rearward, and said fingers. being flat and having their longitudinal edges formed to fit the rear end of a. heel from top to bottom, and being supported by bolts 27, which pass perpendicularly through said bracket arms, so that said fingers extend convergent-1y and are adapted to be set, so that their lift-engaging edges incline toward eachothcr from bottom to top, such adjustment being particularly desirable when high heels, which tape-r considerably from base to top, are to be built.

A pair of heel-forming fingers 28 are pivoted on the rear end of each arm 22, in position to engage the breast end of a heel, and coil springs 30 are preferably provided which normally act to hold said fingers against stop shoulders in forming position, but are adapted to yield readily to permit said fingers to swing rearwardly, so that the form may be withdrawn from a heel. Each pair of fingers 28 has a lug 32, which is arranged to extend oppositely thereto, with relation to the pivots thereof, beyond the outer sides of said arms 22, and a pair of abutment rods 34 are mounted in the ribs 18, of the table 16, in position to engage said lugs 32, when the form is in lift-receiving position, buffer springs 85 being provided between the opposite ends of said rods to those which engage said lugs, and adjusting screws 36, which are adapted to vary the tension of said springs.

'A latch t0, outwardly pressed by a spring 4 1, is arranged in the form plate 20, in position to engage the outer end of a rigid bracket 42, mounted on the right hand rib 18, to lock the form in its outermost position against inward movement, and an operating lever 44, having an uprighthandle thereon, is pivoted on a vertical pin 46 in the plate 20 and has a toe 48 arranged to engage a shoulder on the latch 40, so that, when said lever is swung rearwardly, it will cause the latch to be disengaged from the bracket 42. it

A rod 50 is secured in the table 16 and has a stop-lug 52 threaded thereon; and adapted to provide a positive stop for the form plate at the point at whiehthe latch 40 engages its shoulder on bracket 42, to lock the form againstcinward movement.

A rod 54 is mounted to slide vertically in suitable lugs or brackets on the machine frame and a bell-crank lever is swiveled on the upper end thereof, one arm 55 of which has a handle at its end, and the other arm 56'of which has a vertical rod 57 adjustably mounted therein and having a clamping plate 58 on its lower end, the arrangement being such that said plate 58 may be carried to and from a position to clamp a pile of lifts held in position by the heel-forming members 26 and 28. A spring 60 is arranged on the rod 54 between a lug 59 on the frame and a collar 61 on the rod and acts nor: mally to sustain said rod in a position to hold the clamping plate 58 at a suitable distance above the form, a stop nut 54k threaded on the lower end of said rod 54- being arranged to engage a guide lug 59 and limit the upward movement thereof.

A vertically disposed driver rod 62 is arranged to reciprocate in a guide tube 63 see cured at itsupper end to the table 16 and depending therefrom, said rod 62 having a small bore,in its upper end to receive a driver 64 and the bore in the upper end of tube 63 being of corresponding diameter to provide a suitable guide therefor. A bracket is mounted on the frame, and a sleeve 65 is arranged to slide therein, and has a spring 66 thereon between said bracket and an ad justable nut 67 on its lower end. A head 65' is formed on the upper en d of said sleeve 65, providing a shoulder which limits the downward moven'ient thereof. The rod 62 is threaded in said sleee65 to permit vertical adjustment of the rod 62 therein, there by to vary the initial position of the driver according to the length of the nail. to be driven.

A bifurcated operating lever 70 is arranged astride both the rods 62 and 5 and is connected, at an intermediate point, by links 72 to the'head 65 of sleeve 65, and. at one end, by a pivot 73, to the rod 54. The opposite end of the lever 70 is connected to a treadle 74 by a chain or cable 76, which passes over a roll 77.

Any suitable means for causing the form, by its inward movement. to move the latch 12 out of operative position may be provided, the means shown comprising a yoke 80, which is connected to the latch 12 and extends about the rod 10, and a slide 82 which is pivoted to said yoke and extends about the tube 63 and has its end in position to be engaged by a depending arm 84 on the form base plate 20, when the latter is pushed back to its rearmost position. An operating lever 86, for the carrier driving mechanism, is also arranged to be engaged by the form on its return movement, as in said prior machines.

The manner in which the heel-building operation is performed with the above-described mechanism is as follows The form base plate 20 is drawn out against the stop-lug 52 in which position it is locker by the latch 40, the forming memlll) a noted that,

bers 28 being thus held firmly in forming position by the engagement of the lugs 32 thereonwith the ends of the rods 34. The

lever arms 55. and 56 are swung to a position in which the clamp 58 is held at one side of the form. it suitable building nail is placed head down, so that it rests on: the driver 64, as shown in- Fig. 2,,andthenthe cemented lifts are placed inflthe form, in the usual manner, until theheel is built to the required height. The. clamping plate 58 is then swung intoposit'ion over the heel and the treadle74is depressed causing the end of the operating'lever 70 connected thereto, to be lifted; 'The tension ofithe spring 60, on rod 54,. is made substantially less than that of the spring 66, so that, dur

ing the first part of this movement, the lever.

70 will swing on the links72 as a fulcrum.

building nail to be driven through the heel, and clinched against the plate 58,v which latter resists the force of; the driving movement. The treadle is then released, sothat the heel-clamping and nail-driving parts returnfto their normal positions. It will be during the entire clampingoperation, the pile of lifts willbe securely held in heel-form and will not be-permitted to slip out of position. I a

The operator then pushes rearwardlyon the handle 48, causing the lever 44 to be swung in this direction to a limited extent. This movement causes the withdrawal of the latch 40, so that it becomes disengaged from the bracket 42, and, as further movement of the lever, beyond what is necessary to release the latch, is. stop, further inward pressure onthe handle 48 is entirely effective to cause. the form plate to be slid inwardly, sothat the-heel,

which has just been assembled, and provided with a building nail, will be slid along on'the'table 16 onto one of the plates 5 beneath the clamp 8. and. when this point is reached, the arm i nndtrip the latch 12, so that the clamp will be released and the heel. clamped on the plate. i

When the form carries the lugs 32 away from the ends ofrods 34;, the breast-ens gaging members of the'form will. be unlocked, so that they willbe merely held in position by springs 30. It will be apparent, therefore, that when thejheel has been causing the rod 54 tobe drawn downward 62 andfcausing, by continued movement, the

prevented by a suitable 84 will move the slide, .82.

clamped one ofthe presses and the form is drawn back to build a new heel, the -form members will yield and readily become disengaged from the clamped heel, as shown in Fig. 5, so that the return of the form may be accomplished without. delay, and, as the form reaches its outermost position, the

lugs 32 will re-engage the rodsl34, which latter, through the action of the springs 35, I

serve asbufi'ers, as-wellj1as a part: of the locking means for the form members. j The form will be automaticallyrelocked when the, latch in position I toreengage the bracket 42, so that the above-described operation may be repeated. I
