Application filed September 2 1, 1921. tieriallt'c. 502,84t'7.
3 To all whom it may concern:
Be it known that l, citizen of the United States, and a resident of the city of New York, borough the Bronx, in the county oi Bronx and State of New York, have invented a new and 1mltl proved ltleel-Breasting Machine, of which the followmg is a tull, clear, and exact de- SGI'lPtLOIl.
Tl hisinvention relates to shoe machinery.
. and particularly toan. improved machine for moved to the cutter and then out without any (ill desired shape, the arrangement bein trimming the front of heels and has for an ObJGCiJtO provide a construction wherein the unfinished heels may be fed into the machine and automatically cutat the proper place.
Another object of? the invention is to. provide a machine for cuttingheel fronts to the V 3; such that the heels are manually placed in the machine at one point and automatically further consideration by the operator.
A still further object oii the invention is to provide a cutter or trimming machine for cutting the fronts of? heels of foot wear, the construction including; a rotatable plattorm with holders tor heels positioned ,on the platform to bring; the heels in operative position adjacent the cutter so thatasthe cutter moves the heels will be successively cut. 1 p i A still further object is to provide a heel cutting machine in which the heels may be fed in at a highrate of speed or at a low rate of speed accordingto thespeed of the machine, the construction being such that the failure to teed hlank heels to the machine will notinjure the machine. Inthe accompanying. drawings- Figure 1 is a top plan view with one edge broken away showing one embodiment of the invention.
Figure 2 is a side view of the machine sho'i-vn in Figure 1. i i
Figure 3 is a sectional viewthrough Figure 4: approximately on line 3-3. 1
Figure 4i is a sectional view through Fig;- ure 1 approximately ojuline Referring; to the accompanying drawings by numeral, 1 indicates a foundation of any desired kind which supports the various posts 2, 3 and 41, which posts supportthe driving shaft 5 in suitable journal; boxes. An upstanding bracket 6 is also carried by the base 1 and acts as a support for the turntable 7 i and certain other parts. Suitable Acorn t iorronn, a.
standards 8 and 9 are connected to the base- 1 and act as supports for an arc-shaped plate lOwhich is formed with rounded cam ends 11 and 12 and a horizontal section 13. This plate or cam member acts as means for receiving the roller 14: and elevating said roller to a certain place and holding the same elevated durmg the travel. of the turntable 7 for a short distance. An upstanding bracket. 15 acts as a support and guide for the slidtltl inn; head 16 which is arranged in a suitable dovetail in the bracket 15 and carries a cutter or knife 17 held in place by a suitable locking screw 18. Preferably, the knife 17 is provided with a slot so that a vertical adjustment thereof may i be secured at any time. The sliding head 16 is provided with an extension '19 to which one end of the link 20 is pivotally connected by a screw 21, the
opposite end otsaid link being pivotally connected to one end otthe crank 22 bya pin The opposite end of the crank 22 is connected to the shaft 5 so that when said shaft rotates, knife 17 will be reciprocated in a vertical direction.
In the particular construction shown in the drawing. one revolution otthe shaft 5 will rotate the table 7 one quartercl' a revolution and will cause the knife 17 to form one complete back and forth movement. using the. machine it is intendedrthat the unfinished heel shall. be placed on the table 7 and moved aroundto a position beneath; the knife 17, which knife cuts the front thereot so that the heel will present the proper appearance. ltn order to carry. out this intention, the table? is rigidly connected with a central shaft 24 (Fig. 4) and said shaftextendsthrough the turned ever end; .25. of the bracket 6. Securedato the lower end otthe shaft 24 is a notched wheel and continually in mesh with the bevel gearl 3 1 keyed or otherwise rigidly secured to the shaft 5. By this construction and arrangedill ment, whenever the shaft rotates one revolution, the notched wheel or cross 26 will rotate one quarter of a revolution and acting through the shaft 24 will rotate the table 7 a quarter of a revolution.
In order to permit the knife 17 to properly cut the heel, the table must be stopped at the proper point for a short time to permit the knife to operate. In. order to accomplish this and to prevent too greater movement of the table under the action of momentum, a notched lug 32 is provided on the bottomof the table 7 for each of the notches of the notched wheel 26. A lever 33 is pivotally mounted at 34 on the bracket 6 and has one-end 35 positioned to move into the notched lug 32 at the proper time while the opposite end is formed with a hook or abutment 36 co-acting with the cam 37 rigidly secured to the shaft 5. A spring 38 tends to normally hold the lever 33 so that end will remain in the notched log 32.
During the operation of the machine, the cam 37 moves in the direction of the arrow shown in Figure 4 and, consequently, at the proper time the inclined face 39 engages the hook 36 and raises the same against the action of spring 38. This will cause the end to move out'ofthe lug 32. The parts are so se't that this occurs just as the wheel 27 of arm 23 is entering one of the notches 26 of the notched wheel 26. During the quarterlyturn of the table caused by the movement of arm 28 as it shifts the wheel 26, end of lever 33 is maintained in an inoperative position as the hook 36 is still riding'ov'er the cam 37. At the moment that book the table 7 has reached the proper position, 36 will snap over the end 40 of cam 37 and at" the'same time the end 35 of lever 33 will move into the notched lug 32 that has been brought to the proper point. In this way, the end 35 quickly moves into the respective notched lugs 32 as they are brought to the proper position, whereupon the table 7 will be locked in a stationary position and held until after the knife 17 has performe'd its operation. At the same time that the knife performs its operation, the operator may feed or place a new heel in position on the table as hereinafter fully described.
It will be seen that by continuously rotating the shaft 5 by any suitable power, the
. greater or less movement could. be provided according to the number of notches 26' and the way the other parts are positioned. As
shown in Figure 1, there are four duplicated sets of mechanism of identical construction and identical operation, there being one set for each of the notches 26 in the wheel 26. For the convenience of description the point marked A in Figure 1 will be known as the feeding station and the point marked B as the cutting station.
As the machine operates a workman places an unfinished heel on the plate 41 and as soon as the table 7 has moved sufiiciently over the wheel 14 to move off of the cam member 13, the clamping shoe 42 will more downwardly under the action of spring 43 and press the unfinished heel against the plate 41 which may be fiber or some other slightly yielding material. At the same time that the shoe 42 moves downwardly for pressing the heel against the plate 41, side shoes 44 and 45 will move laterally for centering and clamping the heel against lateral shifting movement while a stationary or fixed rear brace 46 prevents any rearward movement. By the time that the table 7 has moved a quarter of a revolution, the heel is rigidly clamped in place and the next set of mechanism has moved to station A from station T5. The finished or cut heel is rcleased from the shoes 42, 44 and 45 as it approaches station A and may be quickly removed by the operator and'an unfinished heel substituted. which unfinished heel will be gripped as above stated when the table 7 moves a sufficient distance for roller 14 to move off of the cam member 13. The shoe 42 is preferably provided with a threaded stem 42 screwed into the head or enlarge ment 47 of an arm 43. which arm extends through a suitable aperture 49 in the table 7 and which is provided with a bifurcation for accommodating the roller 14. Preferably. a locking nut '42" is used for locking the threaded shank or shaft 42 against accidental shifting. The arm 48 and roller 14 are held properly in place by a suitable guide rod 50 extending upwardly through the table 7 and around which the spring 43 is positioned. By the action of spring 43, shoe 42 quickly clamps the unfinished heel on plate 41 while a different mechanism is provided for operating the shoes 44 and 45. Each of these shoes is provided with a shank 51 on which is pivotally mounted a square block 52 fitting into a. rectangular notch 52 formed in the respective arms 53 and 54, which arms merge together and form an inwardly extending shank 55 in which a slot 56 is formed, which slot permits the lug 57 to project therein and act as a guide for the arms 53 and 54. A retaining plate 58 is held in place on lug 57 by suitable screws 59. A hook 60 is connected or formed integral with the shank 55 and is adapted to receive one end of a spring 61, the opposite end being connected with a centrally positioned post inseam 62. lln order that the arms 53 and 54 may move radially towards the center for shifting the shoes 14 and toward each other as shown at the bottom of Figure 1, a depend.- ing lug 63 (Fig. 4) is provided on the shank and carriesa pin or shaft 64; on which a roller 65 is mounted. The roller tltiis adapt ed to engage the cam 66 rigidly secured to the bracket 6 by screws or some other desirable way. As any particular set of mechanism moves from the cutting position at station B, the roller 65 thereof will engage cam (36 about the same time that the roller In using the machine, heels which have been properly made and trimmed on the sides and the rear are inserted so that the front will be cutoff at the desired angle in order to present the desired appearance; ll henthe cut heel has been discharged from the machine, it is finished and ready for use. During the cutting operation of theknife 17, suitable pressure is used and in order to pre vent the deflecting of the table 7 at that point, a supporting bracket 68 is provided as shown inlligure 2, which bracket is preferably provided with. a roller 67.
