JOSEPH F. SOULE, OF BROOKTON, MASSACHUSETTS.

BOX-TOE-FORMING MACHINE.

SPECIFICATION forming part of Letters Patent No. 368,025, dated August 9, 1887.

Application filed December 17, 1886. Serial No. 221,835. (No model.)

To all whom it may concern:

Be it known that I, JOSEPH F. Source, a citizen of the United States, and a resident of Brockton, in the county of Plymouth and State of Massachusetts, have invented certain new and useful Improvements in BoX-Toe-Forming Machines, of which the following, taken'in connection with the accompanying drawings is a specification. I

This invention relates to improvements in machines for making box-toes for boots and shoes, and it is carried out as follows, reference being had to the accompanying drawings, wherein--- Figure 1 represents a plan view of the machine. Fig. 2 represents a vertical section on the line A B, shown in Fig. 1. Fig. 3 repre sents a crosssection on the line 0 D, shown in Fig. 1; and Fig. 4 represents a cross-section on the line E F, also shown in Fig. 1.

Similar letters refer to similar parts wherever they occur on the different parts of the drawings.

a is the frame of the machine, in bearings in which is located the driving-shaft b, to which a rotary motion is imparted by means of beltpower applied to thepulley c,secured to shaft-b.

b is a pinion secured to the shaft 1) and gearing in the'teeth of. the gear (1, secured to the cam-shaft d, that is located in suitable bearings in the frame a, as shown in Fig. 2. To the shaft d is secured the double-faced cam 6, having cam-grooves e and e on its two opposite faces, as shown in Fig. 2.

The cam-groove e and its connecting mechanism to the male die serves to move thelatter to and from the stationary female die, and the cam-groove e and its connecting mechanism to said male die serves to move the latter up and down to and from the yielding follower.

The mechanism for imparting a horizontal forward-and-back motion to the male die is carried out as follows: WVithin the cam-groove e is located the roll f upon the pinf, which latter is secured to the block f that is guided in stationary ways secured to frame a. The upper end of the block f is hinged or pivoted to the lever g, which is hung at g in its rear end to frame a, as shown in Fig. 2. Between the ends of the lever g, I make through the latter aseries of perforations, g g g, to either the is obtained.

one of which (according to the desired motion to be given to the male die) is hinged the lower end of the link It, the upper end of which is hinged or pivoted to the inner ends of the knuckle-joint levers i and k. The rear end of the lever t is hinged to the horizontally-adjustable block '6', which latter is made adj ustable in guides in the frame a by means of the screw 2', that is screwed through the frame a and loosely connected in a suitable manner to the rear end of the block 43, as shown in Fig. 2, and by this arrangement an additional adjustment of the forward motion of the male 2' is a set-nut on the screw t', as shown in Figs. 1 and 2, for the purpose of firmly securing the screw 6 to frame a after the position of the block t" has been adjusted.

To the forward end of the lever 75 is hinged the block Z, that is horizontally movable in guides in the frame a.

The horizontally-mov-.

able block Z has a vertical perforation, in which the male-die rod m is movableup and down, to the upper end of which is secured, by means of a nut,m, the male die m, as shown in Figs. 1, 2, and 3. The lower end of the maledie rod in is hinged to the block 0, that is guided in ways attached or secured to frame a, and is provided in its lower end with a pin, 0, having roll 0 located in the cam-groove e on the cam c, as shown in Fig. 2.

To the upper front end of the frame a is secured the stationary female die 19, having on its rear side a semicircular recess, 19, corresponding in shape to the semicircular front end of the male die m, and to the top of the said female die 1) are secured the adj ustable gages 12" 2", as usual, by means of set-screws 19 19 or equivalent devices.

Below the male die m within the recess 12 in thefemale die is located the follower-die q, the upper surface of which is made to correspond with the under surface of the male die m", as is usual in machines of this kind. The follower-die q is secured to the follower q, that is vertically movable in the block r against theinfluence of the coiled spring r, located around the said follower q between the top of the block r and a collar or projection near the 7 ICO by means of the thumb-nut q, arranged on the lower screw-threaded end of the said follower q, as shown in Fig. 2.

The block r has on its rear side a perforation, r, in which is loosely inserted the supporting-plate .9, having trnnnions s s in its ends located in bearings s s, secured to frame a, as shown in Figs. 2 and 4-, to enable the follower and its die to rock forward and back; and for the purpose of causing the forward end of the follower-die to bear against the bottom of the recess 1) in the female die 1) during its up-and-down motion, I secure to the plate 8 a pair of springs, s s", the lower ends of which are located inslits in the stationary projections s s 011 the frame a, as shown in Figs. 2 and I. The upper portion, 1-, of the block r, where it surrounds the plate 8, is supported and made to rock sidewise in a recess, 8, in the upper central part of plate 8, as shown in Fig. 4;, to allow the followerdie to automatically adjust itself to the male and female dies during its downward motion.

In connection with the machine I use an automatic picker to throw off the box-toes as they are finished, and it is carried out as follows: To the upper end of the male-die rod in is secured one end of a spring-wire, t, or suitable spring projecting to one side of the machine, and having its free end located below and resting against the under side of the male die, and to such free end is connected the link or wire t, the rear end of which is connected to a beltcrank lever, t, pivoted at t" to frame a, as shown in Fig. 2. The other end of the bell-crank lever t" is provided with a link or wire, 11, the lower end of which is connected to a lever, t pivoted to frame (I, as shown in Fig. 3, the free end of which normally rests against the periphery of the cam-wheel 0 while the boxtoe is being formed, and as soon as a box-toe is finished it is thrown out and off from the male die by the picker 1, which is at this moment liberated by the free end of the lever i dropping into a cavity or recess, 0, on the periphery of the cam-wheel e, as shown in Fig. 3.

a is a hood and receiving-tube, into which the finished boxtoes are delivered by the picker device.

The operation of the machine is as follows: The shaft b is set in rotary motion by beltpower applied to its pulley c, as hereinbefore set forth, and the female die 1) is heated by means of lamp or other suitable heating device placed below it, as is usual in machines 'f this kind. The previous]y-cutout blanks nade from leather-board or other suitable material) are then taken one by one and placed in proper position on the top of the female die 19 between the gages p and held in such position by the operator until the blank is nipped and molded between the female and male dies, which is accomplished by the downward and forward movement of the male die. After the blank has thus been shaped the male die recedes and ascends, causing the now-finished box-toe to be automatically delivered into the hood to by the agency of the automatic spring-picker f, as hereinbefore set forth. Another blank is then placed on top ofthe female die, and so on.

Having thus fully described the natn re, construction, and operation of my invention, I wish to secure by Letters Patent and claim- 1. In a box-toe machine having stationary female die and vertically and horizontally movable male die m, the automatic springpicker 1., attached to spindle m or any of its parts,and having means, as described, by which it is released to automatically throw off and eject the box-toe when finished, as herein set forth.

2. In combination with the stationary female die and movable male die m, the antomatic picker device, as described, consisting of the rotary wheel 0, having notch or recess a, the pivoted lever l link t, lever t, link if, and spring t, secured in one end to the maledie spindle m or any of its attachments, asand for the purpose set forth.

3. In abox-toe machine, theherein-described mechanism for moving the male die to and from the female die, consisting of the camwheel 0, pin or roll ff, block f, lever g, link h, and knuckle-levers i 7;, connected tolink h, as and for the purpose set forth.

4-. In combination with the stationary female die and vertically and horizontally movable lnaledie m, the follower q q, adapted to yield in the block 1' against thcinflucuee of spring 1', the block 1' being supported and adapted to rock on the pivoted plate .9, said plate having springs s" a resting against projections s" s on the frame for the purpose of automatically adjusting the said follower relative to the male and female dies, as set forth.

In testi mony whereofI have signed my name to this specification, in the presence oftwo subscribing witnesses, on this 8th day of November, A. D. 1886.
