SPECIFICATION forming part of Letters Patent No. 634,397', dated October 3, 1899.

Application tiled September 13, 1998. Serial No. 690,880. (No model.) l

To LZ/f uf/tom, it 777mg/ con/cern:

Be it known that we, CHRISTIAN DANCEL, residing at New York, (Brooklym) county of Kings, and JACOB RUPERT SCOTT, residing at New York, county of New York, State of New York, citizens of the United States, have invented new and useful Improvements in Machines for Forming Boot or Shoe Counters, of which the following is a specification.

This invention consists in certain novel features of construction set forth in the following specification and claims and illustrated in the annexed drawings, in which- Figure 1 is a front elevation ofthe machine. Fig. 2 is a side elevation of Fig. 1. Fig. 3 is a view like Fig. 2, showing the counter-carrier moved forward or away from the main body of the machine to receive a blank. Fig. 4C is a section along t t, Fig. 1. Fig. 5 is a section along u u, Fig. l. Fig. G is a section along o o, Fig. 5. Fig. 7 is a section along w w, Fig. 5. Fig. 8 is a section along a: x, Fig. 1. Fig. 9 is a section along y y, Fig. 1. Fig. 10 shows a counter. Fig. 11 shows a blank for a counter. l

rlhe frame or support of the machine isJ shown at 1 and the customary fast and loose pulleys at 2, Fig. 2, the fast pulley driving the worm-shaft 3, Aengaging the worm or gear wheel at, driving shaft 5. As seen in Fig. 9, this rotary shaft 5 does not extend clear through the machine, but only a part way across, and a second shaft (j is fixed or nonrotatably secured to a suitable part or side of frame 1. A rotary bed 7 is con nected or keyed to shaftI 5, but sits loosely about the fixed shaft 6, so' that it rotates with shaft 5. This rotary bed 7 is provided with or carries a last S, jaws 9, and wiper 10, and instead of having only one set of such parts it'is found that work is expedited by having a series of such parts on the bed. In the drawings these parts are shown in duplicate on opposite sides of the bed to be alternatelyor successively brought intoaction. A description of the operation of one last, with its wiper and jaws, will of course explain the action of the others.

-A counter-blank 11', Fig. 1l, having been placed about the last or form 8 and pressed by the jaws 9 and wiped by wiper 10 is brought into the counter shape shown at 11, Fig. 10, the wiper forming the lap or rand 12,. The

blank 11 is delivered to the last 8 bya eounter carrier or feeder 14, Fig. 3, the action of which will be presently described.

The jaws 9 swing on pivot 15, Fig. 7, and are compressed about the couuter-blankor toward the last S by slides 16, which are actuated by cams 17, made to rotate or oscillate in suitable bearings in the rotary bed 7. These cams have arms 18, and at the two sides ofthe frame 1 are suitably applied roller- studs 19 and 20, Figs. 1, 3, and e. As the bed 7 rotates and carries the arms 1S against studs 19 the cams 17 are rotated or set to lock the slides 16 or to compress jaws 9 toward one another. The contact of arms 18 with studs 2O will move cam 17 to return or unlock the jaws 9. The slides 16 are shown in sections or two parts with interposed elastic or yielding pads 21, Fig. 9, such as rubber, so as to avoid absolute rigidity, which might causebreakage. Rollers 22, Fig. 9, between slides 16 and jaws 9 will cause a rolling or easy motion ofthe parts. The jaws 9 could be'opened by returning-springs 23, Figs. 1 and 7; but when each cam 17 is made double-acting to positively lock and open the jaws the springs 23 can be omitted. The wiper has two movements, one sliding to lap over the edge 12, Fig. 10, of the counter and the other a pressure toward the center or shaft G to smooth said lap or rand 12.

The slide 25, Fig. 1, carrying Wiper l0, moves along guides 21 on the rotary bed 7, and said slide gives the lapping or wiping motion to the. wiper 10. To the wiper-slide 25 at 2S is fulcrumed lever 26 27, the arm 27 giving the pressing movement to wiper 10. The slide 25 is engaged or actuated by leverarm 29, Fig.,5, whose fulcrum or shaft 30, Fig. (i, extends to opposite sides of the rotary bed 7 and has suitable bearings on such bed. At one end of shaft is the arm 3l, whose end or roller when bearing against cam 37, Fig. 4, holds arm 29 raised or the wiper away from the last to allow a blank to be put in place. The cam 37 is suitably fixed to a side of frame 1, and as the lrotary bed 7 rotates the arm 3l passes away from cam 37 and the arm 31 of fulcrum 30 strikes roller 3S, so as to cause the wiper to be slid or pushed over the edge of the blank projecting beyond last 8, so as to give the lap 12. As by the con- IOO tinued rotation of the bed 7 the arm 31 is brought back into contact with cam 37, suoli renewed contact will actuate lever 29 to withdraw the wiper for leaving the finished counter free to be removed. The pressure of the wiper is effected by arm 104, Fig. 6, suitably secured to end or part 32 of the hub or sleeve 39, seated about shaft 3() and having the toggle arms or connection 35 and 36, Fig. S, reaching to arm 26 of lever26 27. Secured or fixed to a side of the frame 1 are the rollerstuds 40 and 41, Fig. 1. As the rotary bed moves arm 104 against stud 40 the toggle 35 36 is straightened out to press against leverarm 26 and cause arm 27 to press wiper 10 toward the center point 6 or against the face of last b. The bed 7 continuing to rotate and carrying arm 33 against stud 41 will cause the toggle to be bent for taking the lever 27 off the wiper l0, which latter is then moved by arm 31 and cam 37 away from last S, so as to free the finished counter, which being removed from the last allows a fresh bla-nk to be inserted. The arm 34 being made extensible or telescoping can be set so that the slide or wipe of the wiper is greater or less, as required. 'lhe arm can also be adjustably secured to the head 32. A spring 42, Fig. 4, holds the arm 31 against cam 37.

The toggle is composed of the pieces 35 and 36, connected by the well-known elbow-joint, which allows piece 36 to swing in one direction until in line with piece 35 and then to stop or be held in` suoli alinement until the piece 36 swings back or liexes on piece 35 in like manner as the human forearm alines and exes on the arm. Referring to Fig. S, it is seen that the rotary bed turning in the direction of the arrow carries arm 104 against roller 40, thereby swinging toggle-arm 35 toward last 8. As the outer or free end of toggle branch 36 rests against lever-arm 26, this outer end is held or arrested against moving toward the last, and the swing of arm 35 toward such last will aline the parts 35 and 36, so as to cause them to be alined or extended to full length. The leverarm 26 is thus pressed outward, causing arm 27 to press the wiper 10 inward or against the front or outer face of last 8. By not causing the wiper to be pressed against the last until said wiper has slid or wiped over the last the sliding or wiping motion is easy or comparatively free from friction, and the subsequent pressure of the wiper toward the last or last-face causes the flange 12 to be neatly or firmly bent or set, so as te give the work satisfactory finish. The toggle branch 36 is not connected to lever 26, but simply abuts against the same, this toggle 35 36, as seen in Fig. 6, being located at about the center of rotary bed 7, while the shaft 39 of arm 35 has the arm 104, located at one side to be in the path of the studs 40 and 41 on the frame 1. The arms 35 and 104 are rigidly connected to shaft 39, and arm 104 may have a roller, as seen in Fig. S, for relieving friction when this arm 104 glides past or strikes the studs 40 and 41.

The last S is slidable or movable toward and from the jaw joint or pivot 15, so as to shape or press the counter or blank firmly into the jaws. The lever 43 44, Fig. 5, is fulcrumed at 45 on the rotary bed 7, and its arm 43 has a set-screw 46, which can be made to bear against or hold the last S in proper adjustment. The lever-arm 44 has a roller or bearing-block 47 in contact with the cam 48, which, as seen in Fig. 9, is fixed or secured to the fixed shaft 6, so as to remain stationary, while the tubular or chambered bed 7, with the last S and fulcrum 45, rotates about such shaft 6. As the lever is carried about, its arm 44, contacting with the high part of cam 48, will move arm 43 to suitably slide or press last o' into jaws 5), and at the point ofjntensest pressure the cam 4S, Fig. 5, can be provided with a hardening 49, such as a piece of hardened steel, to resist friction or wear. An elastic or yielding pad 50, Fig. 5, such as rubber, between block 47 and lever 44 will prevent such absolute rigidity as might cause breakage. As seen in Fig. 5, the last can be held to lever 43 or set-screw 46 by a spring 52. In order to relieve the pivot 15 from the pressure of jaw 8 and lever 43, the jaws 9, as seen in Fig. 5, are set into a recess or their upper or pivot portions bear against an overhanging portion 51 of the rotary bed 7. This seat 51, while not preventing the requisite degree of play or opening of the jaws, will save the pivot 15 from having to stand the strain or all the strain of lever 43, so that breakage or derangement of the pivot is avoided.

rlhe counter carrier or feeder 14 when out in the position shown in Fig. 3 is in position to receive a blank 11', and by moving toward the machine, Figs. 2 and 5, such counter-earrier will deliverthe blank onto the last. This blank-carrier 14 is adapted to slip or telescope into the sleeve 53, Fig. 5, and as said sleeve presses carrier 14 against last 8 and telescopes or slides over such carrier 14 such sleeve 53 slides the blank 11 0E the carrier 14 onto last 8, Where it is gripped by jaws 9, to be operated on or carried about by the rotary bed 7. The counter-carrier 14 has a stem 54, Fig. 5, extending or sliding through nut 55, and a spring coiled about stem 54 tends to move o r hold the carrier 14 out of sleeve 53. j By screwing the nut 55 more or less into sleeve 53 the carrier 14 is gaged or allowed to slip into sleeve a less or greater distance, and the blank will thus be slid onto the last, so as to leave a greater or less projecting edge portion to form a greaterorsmaller lap 12, as required. The sleeve 53 is carried by arm 56, which has a stud or movable connection 57 in the slot or guide 58 of plate or head 59. The plate 59 is mounted on arm 60, pivoted or swinging at 61, Fig. 4, on the arm 62,depending from or connected to the frame 1 or to a cross- IOO IIO

ISO

bolt G3 of such frame. The way or guide 58 is cu-t or shaped so as to be centered or to lie circularly or concentrically about shaft 5, so that when the plate 59 has moved to the last 8 the arm 55, moving along the segmental way 5S, will cause the carrier 14, with the blank, to follow the rotating bed 7 or its last S a certain distance until the jaws 9 have secured a hold on the blank.` This motion of arm 60 and the ymotion of arm 5G along way 58 are attained by cams or grooves on wormwheel 4, Figs. 2, 3, and 9, the inner cam 64 being made to carry the head or support 59 toward and from last 8 and the outer cam 65 being made to move the connection 57 or arm 56 along way 5S. ,f

The frame 1 carries a fulcruin 66, Fig. 2, on which are shown two levers. The arm 67 of lever 67 68 on this fulcrum 6G is actuated or engaged by cam 64, and the arm G9 of the other lever 69 70 is engaged by cam 65. The lever-arm G8 connects by link 71, Figs. 2 and 3, with arm 72 of bell-crank lever 72 73, having arm 73 connected by link 74, Figs. 3, 4, and 5, with head 59. As the cam (34 moves from the position shown in Fig. 3 to that shown in Fig. 2 the lever-arm 08 is actuated to move levers 72 73 for swinging the arm 60, with head 59, arm 56, and counter-carrier 14, to the last S or rotary bed 7. The lever-arm 70, Figs. 2 and 3, has link 76 connecting with arm 77 of lever 77 78, having arm 7S connected by link 79 with the lever or arm 80, fulcrumed at 63 and connected by link 8l with the pin or traveler 57. As the cam 65. oscillates lever-arm the parts 76, 77, 7S, 79, 30,`

and S1 are moved to carry the arm 56 back and forth along guide 58. The fulcrums of the levers 72 73 and 77 73 are shown in the form of suitably long shafts 82 and 83, Figs. 1 and 3, having the bearing S4, Fig. 5, carried or supported by the arm or riser S5, Fig. 4, on cross bar or bolt 63.

In placing the blank 11" onto the carrier 14 such blank can be properly gaged or centered by the fingers S6, Fig. 2, properly adjusted on cross-bar 37, carried by arms 88, extending from frame 1. A presser or linger 89 is arranged over the center vof the carrier 14, Fig. 3, so as to press or hold the counter-blank onto such carrier. Such finger S9, as seen in Fig. 5, is surrounded or engaged bya spring arranged to press this finger onto the blank on the carrier 14; but of course this finger or spring-piece 89 does not prevent the blankV and carrier 14 from moving away from the position shown in Fig. 3 toward last 8. When the blank 11 is placed onto the carrier 14, such blank is bent by the operator about the carrier and held so bent by fingers 90, Fig. 3, carried by slide 91 on stem 92, Fig. 5, said slide and fingers being temporarily held or pushed into position to keep the blank bent about carrier 14 until such bent blank is pushed lonto the lastI 8 and gripped by jaws 9.

The operation of the device is readily understood. A blank having 4been bent about carrier 14, such carrier first moves to the last 8, and while the blank is being transferred from carrier 14 to the last the carrier traveling along way 58 follows or accompanies the last for some distance until the jaws 9 have gripped the blank. The last 8 being then pressed into the jaws and the jaws being pressed 'against the last or 4blank and the wiper 10 being slid over and pressed against the overlapping or projecting blank portion, the counter is formed, as seen in Fig. 10. Vlien finished, the counter is taken off the last by stripper 93, Figs. 2 and 3. Two strippers are shown for the double-acting machine, such strippers being mounted on arms 94, extendingfroin shaft 95,to which are secured the arms 96. On the rotary bed 7 are arms 102 and 97, Fig. 4, which are applied to suitably engage and rotate the arms 96 with shaft 95 and stripper 93, which latter entering between the last S and the rand 12 of the counter on `such last strips off such counter to leave the last clear for a fresh blank. The shaft 95 has its bearing on an arm 98, Fig. 4, suitably secured to the frame 1.

It has been stated that the cams 17, Fig. 9, can positively actuate the jaws 9 in both directions. By having links 99 connected to the jaws and to the rear or return faces of the cams 17 such positive return or opening' of the jaws can be secured. The jaws 9, Fig. 7, are separate or independent of one another and mounted on pivot l5, so as to swing laterally thereon or about such pivot. The last 8 and jaws 9 being made to act or press independently of one another, each can be made to act at the proper moment and with required force. After the jaws and last are fixed or the last has been gripped by the jaws and the lever 44 has passed the boss 49 such lever 44. or cam 48 is somewhat relieved of pressure. The shaft 6, carrying cam 48, can be keyed fast to a frame side 1 or adj ustably arranged, as by screw and dog-piece, so that said cam and shaft, while non-rotary, can yet be accurately set or adjusted as required. The wiper-actuating lever or arm 34, Fig. 4, is shown provided with a stop-piece or nose 100, which limits the play of said arm by striking against a stop-piece 101 on the rotary bed 7. The sleeve 39, Fig. 6, can be held by a-brake or friction device 103 against improper movement or rotation. The last, wiper, and jaws being so arranged that when under pressure or locked contact with the frame 1 or its studs and cams is avoided until the moment of un* locking, the rotary bed 7 will, between the period of locking and unlocking, move or rotate freely or without any resistance from such frame studs and cams. The travel or rotation of the bed 7 can thus' be effected economically or without waste of power. The

cam or lock 17 for the jaws being so arranged that when Vput in action or the jaws compressed said jaws are held locked and keep a hold on the las't t5, the cam-actuating arm 18 can pass clear of the frame or the locking- IOO IIO

studs 19 without the jaws opening. 'lhc arm 18 clearing stud 19 relieves the rotary bed 7 of the friction or resistance arising from thc contact of such parts 1S and 19, so that the bed can now rotate freely until arm 1S contacts with opening-stud 20. Also, when the wiper has been slid over the edge of the work or counter and the locking mechanism or toggle 35 3G has been locked or straightened by the contact ot' stud 40 said stud has been cleared or passed by arm 33, so that the rotary bed 7 travels or moves freely until arm contacts with releasing or unlocking stud l1. Strain is thus relieved or unnecessary resistance to the movement of the bed avoided.
