MACHINE FOR TREATING BOOTS OR SHOES.

SPECIFICATION forming part of Letters Patent No. 406,826, dated July 9, 1889.

Application filed October 29,1883. Serial No.289,418. (a, model.)

and has for its object to improve the construc-' tion of the same.

One feature of my invention consists of a novel burnishing-tool made of two blocks or pieces, preferably wedge-shaped, each of the said blocks being operatively connected, as

v herein shown, to an eccentric on a drivingshaft, whereby the said blocks are made to; slide or reciprocate in opposite directions to produce a rubbing action of the burnishingtool on the heel of the boot or shoe similar to the rubbing motion made by hand, by which motion a better finish is imparted to the heel. The wedge-shaped blocks of the burnishingtool are arranged with relation to each other, as will be described, so thatwhen the said blocks are moved by each other in opposite directions the surface of the tool acting on the heel will be enlarged, whereby heels of varying heights can be burnished with one tool. One block of the burnishing-tool is preferably made movable vertically to enable heels of different sizes and shapes to beacted upon, and especially when the top lift varies in position on the heel.

Another feature of my invention consists in making the jack adjustable, whereby heels of varying heights may be placed in proper position to be acted upon-that is, the heelpattern plate of the jack is adjusted or brought into position to bring the heel of the boot or shoe in correct working position with relation to the operating-tool. The heel-pattern plate is preferably hinged or made movable to adjust itself to the bottom of the heel of the bootor shoe to obtain a firm or rigid bearing.

My improved burnishing-tool and jack are especially adapted to be used on a boot and shoe machine provided with a number of different operating-tools to act simultaneously on heels of difierent boots or shoes carried by a plurality of jacks, substantially as shown in United States application Serial No. 263,305, filed February 7, 1888.

My invention further consists in providing mechanism, as will be described, whereby 011 one movement of a treadle the jacks are removed from one tool, as a trimming-tool, and placed in position to be brought under a second tool, as aburnishing-tool, when the treadle is restored to its normal position.

Still another feature of my invention consists, in providing an adjustable stop by which'the tripping mechanism of the machine shown and described in the said application may be actuated to stop the revolution of the tool-carrying shafts about the pattern-plates at any desired point, for a purpose to be hereinafter described.

Figure l is a side elevation of a machine 4 embodying my invention; Fig. 2, a detail of the burnishing-tool and its operating mechanism;

Fig. 3, an end elevation and atransverse section of the burnishing-tool detached; Fig. 4, a detail to be referred to; Fig, 5, a detail to moreclearly show the adjustable jack; and Fig. 6, a sectional detail on line 3 11 Fig. 1, to more clearly show the reversing mechanism.

The frame of the machine, comprising the bed-plate A, and standards A A A A A supports the working parts of the apparatus, as in the application referred to. The powershaft a, the tool-shaft a, driven therefrom by belt a and moved longitudinally by the levers a (1 the latter being acted upon by the cam a on the shaft to, having at its opposite end thecam (0 by which the breasting knife a is operated, the shaft a, driven from the power-shaft a by belt 0. and having at its opposite end the gear (r by which the gearing for revolving the tool-shafts a a is operated, are all substantially as in the machine shown and described in the said application. The shaft a has mounted on it two levers b I), (see Fig. 2,) having secured to or forming part of their smaller arms blocks 19 19 which together form the burnishing-tool of the machine. Each block b b is preferably made said blocks are reciprocated or moved by each other, as will be described, the acting-surface of the burnishing-tool will be enlargedthat is, as the wedge-shaped faces of the blocks 6 b move one on the other during .the vibration of the said blocks by the said levers, each in a direction opposite the other and at a right angle to the length of the heel, one of the said blocks, as 19 being at the same time made to move longitudinally in the direction of the heel by the action of the wedge-shaped face of the said block 19 against the wedgeshaped face of the block b, the resultant mo tion of one of the said blocks-via, that one 12 nearest the top-lift end of the heelbeing diagonal, the tool so divided working over a greater surface of the heel in the direction of its length than when the wedgeshaped faces of the blocks are omitted.

The blocks b b are reciprocated, as herein shown, by means of eccentrics b 17 connected, respectively,by eccentric straps and rods to the long arms of the levers Z) I), the said eccentrics being mounted on a shaft 5 having bearings in uprights b b secured, as shown, to the large gear-wheel Z1 mounted on a stud on the upright A, the shaft b being driven by a belt b passed about pulleys Z2 Z9 on the shafts b a, respectively.

The levers b b are both movable vertically, as herein shown, they being each provided with a slot 0, (see dotted lines,Fig. 2,) through which the reduced end of the shaft a is extended.

The shaft ct has mounted on ita sleeve 0', pressed against by a spiral spring 0 encircling the said shaft, the said spring acting to keep the blocks in contact with each other, the lever 19 being pressed against a nut c on the reduced portion ofthe shaft to.

By means of the wedge-shaped blocks heels varying in height can be burnished by one tool, and to enable heels of extreme heights to be burnished by the same tool a set-screw; is provided, the said set-screw being ex-' tended through one block, as 11 and adapted to bear against the other block, as b, when the said screw is turned to force apart the said blocks, as shown in Fig. 3.

The levers b b are pressed down upon the heel, as herein shown, by a spring-c secured at one end to the standard 1) and havingits other end resting on a link 0 to which links 0 0 secured to the levers b b, are fastened,- as shown in Fig. 2.

To simplify construction the bearing-block c for the shaft a is fitted into a slot in the gear-wheel b (see Fig. 4,) and is maintained in its lowest position in said slot by a spring c' flhaving one end secured to said block and its other end to the gear, as shown.

jacks, all radiating from a common sleeve (Z, secured to the shaft d, which is free to rotate in bearings in the standards A A and also to slide longitudinally therein, substantially as in the machine shown and described in the application referred to. Each jack comprises two arms d d but in accordance with my invention the arm d of each jack is made movable, it being herein shown as divided into two parts 2 3, the part 2 having the heel-' pattern plate (1 and the opening through which the breasting-knife a passes being pro; vided with an arm (1 extended between the forked arms of the fixed portion 3, the said arm being pivoted to said fixed portions, as shown in Fig. 5. The arm 01 has connected to it a linkd joined near its opposite end to a lever d pivoted on a stud d on the arm (1 of the jack, the said lever being provided on its under side with a dog or pawl d (see Fig. 1) to engage the teeth of a ratchet-bar d secured to the arm 01 the said dog or pawl being normally kept in engagement with the teeth of the said ratchet-bar by a spring 62 encircling the stud (1 It will be seen that by moving the lever d the hinged or pivoted part 2 of the jack-arm (i may be moved to place the heel of the boot or shoe in correct position to be act-ed upon.

To illustrate: If an exceedingly high heel is to be trimmed and the boot or shoe is mounted in a stationary jack, the knife,which rotates in a fixed path or plane, will act on only a portion of the heel and will trim that portion of the heel near the counter, while the top lift and the portion of the heel near it will be unacted upon; and if a low heel be placed on the stationary jack the knife would trim or cut the upper. WVith my improved tack these defects are obviated, and the heel, whether high or low, may be readily placed in correct position to be acted upon by the knifewithout detriment to the boot or shoe. To obtain a-firm bearing against the bottom of the heel, the heel-pattern d is pivoted, as at 01 to the portion 2 of the jack-arm (i To obtain a nicer adjustment of the heel with relation to the path of movement of the acting-tool, the ratchet-bar will preferably be provided with two rows of teeth set out of line with each other, as shown in Fig. 5.

The gear 12 is provided, as shown in Fig. 4, with two concentric slots 6 e, through which are extended rods or studs 6 e eachprovided with a collar e (see Fig. 1,) which bears against one face of the gear-wheel, the said rods or studs being clamped in place in the slots by nuts 6 screwed upon them. The rods (2 e? are made of sufficient length to strike the levers e e of the reversing mechanism, which is such as shown in the application referred to, the said rods constituting stops by which the travel or movement of the tool-shafts about the heel is limited.

The rods or stops 6 a may be adj ustcd in v the slots so as to act sooner or later on the The machine preferably contains four levers e e as desired-as, for instance, if

the said stud at the rear of the loose gear supporting a sleeve 0 having an arm or arms 0 (see Fig. 1,) upon which are pivoted two gears 0 0 the loose gear 0 engaging and driving positively the gear 0 the gear 0 in turn engaging and rotating the gear 0 the gears 0 0 rotating in opposite directions at the same speed. Between the slotted gears Z2 carrying the shaft (1, and the gear-wheel 0 (see Fig. 6) on the shaft a is an intermediate gear 0 in mesh with a gear 0 The sleeve 0 has at one end an arm 0", (see Fig.

6,) provided with a toe 0 "The arm 0 is jointed to a link 0 carried upward and connected to an elbow-lever 0 pivoted, as at 0 the upper end of the lever being extended up Within the range of movement of one of the stops, as 6 The lower end of the link 0 is connected by rod 0 with a foot-treadle 0 The screw 0, serving for the fulcrum of the elbow-lever 0 also supports an elbow-lever If, one end of which is turned upward and left in the range of movement of the stop e, the end of the lever t being bent in a direction opposite to that of the upper end of the lever 0 so that when the gear 19 moves in one direction, as indicated by.arrow 25, Fig. 6, the rod 6 meets the rod t, and the rod e on the movement of the gear 79 in the direction opposite to that indicated by arrow 25, meets the upper end of the lever 0 The lower end or arm 25 of the lever i has two notches, (see Fig. 0,) No. 1 of which engages the toe 0 of the arm 0 when neither of the two gears o 0 is to engage the intermediate gear 0 The notch No. 2 engages the toe 0, when the gear 0 is to engage the intermediate gear 0 and rotate the gears 11 0. in one direction, as to the right in Fig. 6, the treadle being at such time depressed.

As shown in Fig. 6, the gear 0 is in mesh with the gear 0 and the gears 19 and 0 are rotating in a direction opposite to that indicated by arrow 25.

In the rotation of the gear Z7 the stop a strikes the upper end of the lever o and pushes it down against the action of the spring and through the link 0 forces the toe 0 down into engagement with the notch 1, thus throwing the gear 0 out of engagement with the gear 0 If it is desired to start the gears 19 0 rotating in the direction of arrow 25, the treadle will be depressed to engage the toe in the notch 2, thus throwing the gear 0 in engagement with the gear .0 iVhen the stop 6 strikes the upper end of the lever 15, the toe is disengaged from the notch 2 and the gear 0 engaged with the gear 0 thus producing reverse rotation of the gears 19 0-'that is, in a direction opposite to that indicated by arrow 25. i

To enable the jack-carrying shaft (1' to be moved longitudinally and be rotated by one movement of a treadle, the said shaft has fast on it a disk f, provided with holes or sockets f in its periphery, there being as many sockets or holes as there are jacks. The shaft (1 is prevented from rotating by a pin f on a lever f pivoted, as at f, to an arm f secured to the upright A the said pin entering hole f in the disk f.

The lever f has connected to it a link f, pivoted, as at f, to the end of a lever f which is pivoted, as at f, to an arm f attached to the upright A the lever f being connected by link f to a foot-treadle f pivoted, as at f to a bracketf attached to the upright A The lever f is also connected by a link f! to one end of a lever f, pivoted, as at f to a block f secured to the bed-plate, the other end of the lever f having connected to it a link f secured to the elbow-lever f common to the said application and mounted on a stud secured to the bracket A, the said elbow-lever engaging the tool-shafts a a to move them away from the heels of the boots or shoes when the foot-treadle is depressed, as will be described. 4 j

The disk f is provided with an elongated hub having an annular groove 9*, into which is fitted a block 20, provided with a stud g, extended into a slot g in the curved arm g of an elbow-lever g pivoted, as at 9 to the bracket 9 secured to an upright A the said elbow-lever being secured, as at g, to the link g and having fastened to it the link f, as at g The pivot f has mounted on it a guidebar g", which bears against the upright, and WhiOhChEtS secured to it, as at g a rack-bar g for a portion of its length, with teeth to engage circumferential teeth on the face of a disk g provided, as shown, with a hub g, secured to the shaft (1' by set-screw 9 the said screw being extended into a longitudinal slot g in the shaft to permit the said shaft to be moved longitudinally independently of the disk 9 the latter being held, as herein shown, by forks g of an armfastened to the upright A the said arm acting merely to prevent longitudinal motion of the hub 9 The upper portion of the rack-bar is made smooth-that is, Withoutteethso that when the foot-treadle is depressed the pin f will be withdrawn from its socket in the disk f before the teeth on the said rack-bar engage the teeth on the disk 9 the said raclebar being normally pressed against the disk g by the spring 9 WVhen the treadle f is depressed, the rack-bar 9 and link f secured to the lever f, are moved upward. As the link f is moved upward the lever f to which it is connected, is turned on its pivot and the pin f Withdrawn from its socket. The disk f and shaft d are now free to be rotated. n the further downward movement of the treadle the shaft d is rotated by the teeth on the rack-bar engaging the teeth on the disk g, and at the same time the shaft is being rotated it is moved longitudinally by the slotted curved arm 9 of the elbow-lever 1o 9 which is turned on its pivot by the upward movement of the link f As herein shown, the shaft is given a quarter-turn to bring the proper jacks into position to be moved under their respective tools I 5 when the shaft is moved back into its normal position, which in the present instance is accomplished by a spring when the pressure upon the foot-treadle is removed. I do not desire to limit myself to the par- 2o tieular means shown for producing areciprocation of the blocks or pieces of'the burnishing-tool, as it is evident any well-known cam movement might be substituted for the eccen tries.
