MACHINE FOR Sl-IAPING'HEELS.

SPECIFICATION forming part of Letters ratent No. 761,485, dated May 31, 1904.

Application filed May 6, 1901.

To ai whom it may concern:

Be it known that I, J on J HEYS, of Lynn, in the countyloflEsse and State of Massachusetts, have invented certain. new and useful Improvements'in Machines for Shaping- Heels, of which the following is a specification.

This invention relates to a new and improved apparatus for shaping the upper surfaces of heels; and it consists in the novel features and relative arrangement of parts hereinafter fully described in the specification, clearly illustrated in the drawings, and particularly pointed out in the claims. I 1

Reference is to be had to the accompanying drawings, forming a part of this application, wherein like characters are usedto indicate like par'tswherever they occur.

Figure l in front elevation shows an appa ratus constructed in accordance with my in vention, the supporting-legs being omitted, a

part'of the bed being broken away to show the main shaft. of the apparatus with the clamp removed. Fig. 3 is a Side elevation of the head of'the apparatus, showing the arrangement of the cutter and slotted link or guide. Fig. 4: is a like view with the guidelink removed to SllOW the relative arrangement of the cutter, jaws, heel-blank, and in dotted lines the plane of the cut made by the cutter. Fig. 5 is avertical sectional view on the line 5 5 of Fig. 1 looking in the direction of thearrow, showing the position of the parts before the heel-blank is cut. Fig. 6-is a likeyiew showing the positionof the parts after the cutter has completed its cutting strokep Fig. 7 is a top plan. View of theapparatus. Fig. 8 is a like view. with the vertical bracket and the parts carried thereby removed. Fig. 9 is a detail viewof the cutter, showing the means for. sup-j,

Referring to Fig. 2, 10 represents a treadle pivoted at the rear of the base 2. A clutchllever mechanism 11 connects the treadle 10 with a clutch (not shown) on the shaft 4, whereby the machine may be started and Stopped, as desired. The treadleclutch,-

The jaw 24 carries a clamp 27, corresponding to one side of aheel.

blank resting upon adjusting-plates 23 upon the bed-plate and being engaged by the walls The jaw 22 is .formed- 'with ears 29. 30 represents a vertical stud carried by a socketpiece 31 upon the, top oftlie Standard. 32 represents-a sleeve arrangedto slide upon said stud. Thissleeve is formed with ears 33 and 8c; The clamps 23 and 27 are arranged to hold a heel-blank 28 between them, the heela depending arm 34. (See Figs. 1, 2, and 8.) A link 35 is pivoted at one end to the ears 33 and at its opposite end to the ears 29, whereby ,as the sleeve 32 is moved up or down the jaw 22 will be advanced toward or withdrawn from its complemental jaw 24 to grip or release the heel 28. A bracket 36 is secured by bolts 37 to the under side of the top of the standard 1 beneath the socket-piece 31. (See Figs. 1 and 2.) A rod 38 is arranged at its upper end to slide in a bearing in said bracket 36. A fork 39 is secured to the lower end of said rod and positioned to engage and straddle the main shaft 7. A roller 40 upon said fork engages the cam 9, while a spring 41 upon the rod 38 and arranged between the bracket 36 and a collar 42 upon said rod serves to keep the roller 40 in engagement with the cam. In other words, the cam 9 raises the rod, while the spring 41 depresses said rod when released by the cam 9. The arrangement is such that the gripping ction of the jaws is caused by the spring and the releasing action by the cam 9. As the spring 41 pulls down the sleeve 32 the link 35 is straightened to clamp the heel 28. The sleeve 32 and link 35 act like a toggle; but owing to the action of the spring 41 the toggle is set with a yielding action.

A crank is secured to the gear 8. A bracket 51 is secured to the top of the standard 1 and projects over the to thereof. 52 represents a pintle mounted in the free end of said bracket.

53 represents a link pivoted at one end upon the pintle 52, while at its opposite end it car ries a bearing for a pintle 54. A bell-crank is rigidly secured to one end of the pintle 54 and comprises two arms 55 56. A rod 57 is connected at its lower end to the free end of the crank 50 and at its upper end to the free end of the arm 56, whereby a rocking motion is imparted to the pintle 54. A slotted link or guide 58 (see Fig. 3) is pivoted midway of its ends upon the jaw 24. Set-screws 60, carried by the lugs 61 upon the link or guide 58, are arranged'to engage the jaw 24, whereby the plane of the slot of said guide 58 may be varied and adjusted. A roller 62'upon the free end of the arm 55 of the bell-crank is arranged in the slot of the guide 58 and by its travel in said slot causes the pintle 54 and the cutter, hereinafter described, carried by said pintle to travel in a predetermined path with respect to the plate 21 and the heel 28 supported thereby. By this construction the degree and plane of the cut made in the heel 28 may be varied as desired. The slot in the guide 58 may be curved, as shown, or may have any preferred plane, whether curved or straight.

A lever 7 O is secured at one end to the pintle 54 and is moved thereby. Arms 71 are formed upon the free end of said lever. 72 represents a knife secured at its edges to said arms 71, the cutting edge of said knife being at the right in Figs. 5 and 6. A rod 73 is secured by countersunk screws 74 to the upper surface of the knife.

75 represents a block formed with a recess in which is arranged the rod 73, the block being cut away above the knife, as shown, to permit vertical movement of the knife.

76 represents an ad justing-screw secured at one end to said block and at its other end to the lever. By this construction the plane of the knife in cross-section may be adjusted as desired.

As shown in Figs. 5 and 9, the adjustingscrew 76 is a right and left hand screw, one end fitting in the body of the lever 70 and the other end fitting in the block 75. Said block is formed with wings or grooved lugs which embrace the arms 71 of the lever 7 0, whereby said block is guided when adjusted by the screw. The rod 73, to which the knife 7 2 is secured, as above stated, is inserted endwise into the recess above mentioned as formed in the block 75, said recess being contracted at the lower end 0 face of the block, so as to prevent the rod 73 from escaping from said recess excepting when moved endwise.

77 represents an adjustable block carried by the plate 21, against which the front end of the heel rests. 78 represents a rod pivoted in the brackets 20. A lever 79 is secured to this rod (see Fig. 4) and carries at its free end a finger 80. An arm 81 is secured to this rod in position to be engaged by a lug 82 on the rod 57. The free end of the finger is arranged in an aperture in .the plate 21. The arrangement is such that as the knife 72 returns to its initial position the finger by means of the arm 79 and its connections is actuated to engage the under side and throw it out of the machine.

represents a bracket carried by the upper part of the standard. A pintle 91 is mounted in the end of this bracket, and, upon the pintle 91 is pivoted a sleeve 92, having two arms 92 and a finger 92. A clamp 93 is pivoted to the end of one of the arms 92 over the heel 28. The end of the other arm 92 is provided with a shoe 94, arranged to be engaged by a roller 95 on the jaw 22. The arrangement is such that when the jaw advances to grip a heel-blank the clamp 93 is forced upon the top of the blank, (see Fig. 1,) and vice Versa. The clamp 93 is concavcd on its under side (see Fig. 6) in order not to interfere with the action of the knife. A spring 96 is connected at one end to the finger 92" and at its other end to the bracket 90.

The spring 96 serves to hold the clamp 93 upon the heel 28, while the roller 95 serves to lift the clamp after the cutting operation to permit the ejectment of the heel by the finger 80.

The parts are so timed that the machine automatically stops with the knife 7 2, finger 80, clamps 93 24: 22, and other partsin initial position ready for the reception of a fresh blank.

Having thus explained the nature of the in-' plane of the out of the knife during its stroke.
