SOLE LEVELING OR BEATING-OUT MACHINE.

SPECIFICATION forming part of Letters Patent No. 581,825, dated May 4, 1897. Application filed January 22, 1897. Serial No. 620,217. No model.)

To all whom it may concern/.-

Be it known that I, JOHN J. HEYS, of Lynn, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Sole Leveling or Beating-Out Machines, of which the following is a specification.

This invention has relation to machines for leveling or beating out the soles of boots and shoes, and especially to that class of machines in which the last and form are reciprocated to successively press the entire length of the sole. Heretofore machines of this general class have been so constructed that the last and the mold or form were each mounted on an oscillatory arm, to which power was applied to cause them to operate upon the sole placed between them. Such machines, however, were objectionable because of their liability to tear out and break the stitches in a boot or shoe, especially where a comparatively thick sole was being operated upon, because of the fact that the radii of the two circles through arcs of which the molds and surfaces of the soles upon the lasts moved were necessarily variable, so that the surface of the sole would move more rapidly than the surfaces opposing it. Again, it has been found that where a great pressure is suddenly put upon the sole by machines of this class as previously constructed the leather is bruised and discolored and its marketable qualities are decreased and detracted from, whereas by compressing the leather lightly a number of times the sole may be leveled to the shape of the last without causing such discolorations and at the same time giving it the appearance of having been beaten out by hand, besides prolonging its life and thereby enhancing its value.

Hence the object of this invention is to obviate the objectionable features above recited by constructing the machine in such a way as to prevent any tearing out of the stitches and also to prevent the bruising or discoloring of the sole, as above set forth; and to these ends the invention consists in improvements in machines of this character which are illustrated upon the drawings and which I shall now proceed to describe in detail and then point out in the claims.

Reference is to be had to theaccompanying d rawings,an d to the letters and figures marked thereon, forming a part of this specification, the same letters and figures designating the same parts or features, as the case may be, wherever they occur.

Of the drawings, Figure 1 is a front elevation of a machine embodying my invention. Fig. 2 is a side elevation of the same. Fig. 3 is a vertical longitudinal section of the machine, taken through one set of the molds and lasts. Fig. is a plan view of the machine, partially in section, which section is taken on the line 4 4 of Fig. 1. Fig. 5 shows in detail the gear for actuating the mold-carrier and the last-carrying slide and the means for supporting the same, there also being shown a small portion of the table. Fig. 6 represents in section one of the mold-carriers with a form secured thereon. Fig. 7 illustrates another form of my invention, in which the last is reciprocated a predetermined number of times and then brought forward to have the leveled sole replaced by a new one. Fig. 8 illustrates still another form of the invention, to be employed in connection with the wheel having a cam-groove, as shown-in Fig. '7. Figs. 9 and 10 illustrate the last as being mounted upon links arranged to insure its moving in a straight line horizontally. Fig. 11 illustrates still another form of my invention, to be employed for reciprocating the last.

In constructing a beating-out or sole-leveling machine of the character hereinbefore referred to it is essential that the mold and the last should press the sole between them with a moderate though yielding pressure fora number of times, and hence one of the said parts must be so mounted as to yield, and, as said before, where two oscillating arms are employed upon which the mold and the last are mounted the varying thicknesses of the soles to be leveled cause the variation of the radii of the arcs through which contiguous surfaces of the sole and the mold move, causing that surface of the sole which is pressed against the surface of the mold to move faster than the 1astmentioned surface, with the result that the sole is strained upon the boot or shoe to such an extent as to break the stitches which bind it to the welt or to the insole.

Thereforev in my machine I employ, instead of two oscillating arms or carriers for the mold and last, a single oscillating arm with which a rectilinearly acting or reciprocating slide coacts, and I arrange the gearing in such way that the oscillating arm and the slide travel at precisely the same rate of speed in either direction.

The slide is arranged to reciprocate on a yielding table, and hence it will be seen that the operation of the machine will be precisely the same upon soles of different thicknesses, and there will be no tendency to strain the sole longitudinally of the last or the insole, as was found in machines as previously constructed.

Again, in those machines employing two coacting mold and last carriers which oscillate about opposing pivots the placing of a thick sole between the last and mold causes the surface of the sole which is to be pressed against the mold to be projected radially of the pivot of the last-carrier, and therefore throws it away from the vertical lines of the mold to such an extent that when the carriers are oscillated the sole is pressed against the mold in such way that it is slipped along the mold in the longitudinal lines thereof.v In other words, the curved face of the mold is falsely placed relatively to the face of the sole to be pressed in all cases where a thicker or thinner sole than the one for which the last and mold were fitted is pressed, whereas in my machine the last is mounted to slide tangentially of the arc of movement of the mold and is depressible only in lines transverse to the said tangential lines, whereby the face of the sole, irrespective of the thickness of the sole or height of the last, is always presented properly and at exactly the same point on the mold, and, moreover, I provide for having the mold and last compress the sole a predetermined number of times with a moderate pressure instead of compressing it by one reciprocation of the carrier under great pressure, since I may thus avoid any discoloration and bruising of the sole caused by violently compressing it.

Referring to the drawings, the frame of the machine consists of two side standards a of the shape shown in Figs. 2 and 3 and suitably connected by cross-heads a a and tie-rods a a Vertical rods a 6L5 and a are secured in the cross-head a and are secured at their lower ends, the central one a in the cross head a and the outer ones a in the standards a, as well as in the ends of the crosshead. As the two halves of the machine are alike I shall describe only one of them, but the description may be applied also to the other half.

Depending from the cross-head a are two brackets a in which is journaled the pivotshaft b of the mold-carrier b, which consists of an arm having a segment-plate b at its lower end, which plate is formed at one side with a segmental rack b Preferably the arm, the plate, and the rack are all cast in one, piece. The segmental plate is formed with a recess 79 to receive a mold or form 11 secured therein by screws 1), so that the said mold or form may be removed and another of a different shape or different size may be secured in its stead. Below the mold-carrier is the table 0, having a bowed portion 0, which rests upon a strong yielding spring d, which in turn is supported upon a disk d, having a socket d to receiveit. The said disk is swiveled upon a screw (1 which passes loosely through an aperture in the cross-head (L2, there being a nut d" in threaded engagement with said screw and inserted in an aperture (1 in the cross-head a and by means of which the screw, the spring, and the table may be adjusted vertically.

The table is formed with an annular flange a (see Fig. 5,) through which the rod a passes, and is provided at its opposite sides with a semicylindrical aperture and a guide d coacting with the rod a, so that the table is guided in its vertical movements. Its upper face is formed with a groove d to receive the dovetailed tongue of a slide or last-carrier 6, upon which the last f is mounted, as shown in Fig. 3.

The slide 6 is formed on its outer edge into a straight rack 6, corresponding in number of teeth to the segmental rack 12 which is located directly above it.

Mounted loosely upon the vertical rod a is a sleeve g, held in place by a collar g, pinned to the rod, and formed at its ends into bevelgears g g having the same number of teeth and meshing with the segmental rack and the straight rack, respectively. Thus it will be seen that if the slide or last-carrier be reciprocated it will cause the simultaneous oscillation of the mold-carrier.

I shall now proceed to describe the mechanism which I employ for reciprocating the slide a predetermined number of times and stopping it when it is in its forward position.

It is a longitudinally-arranged main powershaft (see Fig. 3) supported in a hearing it on one of the side standards at its front end and a bracket h at its rear end. Upon the projecting rear end of the shaft is loosely mounted a band-wheel 7L3, which is continuously revolving and from which the power may be transferred by clutch mechanism of any suitable kind.

Preferably I employ a disk h and mechanism (not shown) which is operated by a pivoted lever it, having its lower end resting upon a grooved collar 71 The collar is adapted to be shifted by a bell-crank lever having an arm dwith a yoke fittin gin a groove therein, and also having an arm 2', which is extended to the front of the machine and is provided with a roughened part i which may be depressed by the foot. The lever is pivoted upon the tie-rod a and is normally held upward by a strong spring i \Vhen the lever is depressed, as shown in Fig. 3, the collar h lifts the dog IIO or lever h and connects the band-wheel 7L3, through the internal mechanism, (not shown, with the disk h; but when the lever is elevated, as illustrated in Fig. 2, the band-wheel and the shaft are disconnected. The arm 2" of the lever is formed with a brake i which when the lever is elevated presses against the disk 7L and immediatelylocks it against movement.

The belt-j, which is employed for imparting power to the continuously driven bandwheels 7L3, passes around and under one of the said wheels 72 then up and over an idlerwheel 7t", journaled upon a bracket 71;, connected to the side frame and located centrally of the machine, and then passes down under the other band-wheel 7r.

The shaft IL is formed with a worm h, which meshes with a worm-wheel Z, mounted upon a shaft Z, journaled in a bearing Z in the said frame and having a pitman Z which is connected by a pitman-rod Z with a depending lug c on the slide (2. The said lug 6 projects down through a slot formed in the table 0, which slot extends to a point near the front end thereof.

Now it will be seen that as the shaft h rotates it causes the rotation of worm-wheel Z, and the consequent reciprocation of the lastslide or last-carrier, which in turn causes the oscillation of the mold-carrier, so that the mold and last are successively pressed together from the heel end of the last to the toe and back again. The shaft Z of the wormwheel Z is formed into a pinion Z, the teeth of which intermesh with straight spur gearwheel Z, mounted upon a stud-shaft journaled in the frame an d which is of such a size that it is revolved once for every three revolutions of the worm-wheel Z. The said gearwheel Z is provided with an inwardly-projecting pin Z (see Fig. 1,) which will strike against the upper end of a trip-lever m, pivoted at m on one of the side standards of the machine an d disengage the lower end thereof from an ear i 01] the arm 1" of the foot-lever. Normally the trip-lever is held in engagement with the car by means of a spring 771 so as tohold the lever depressed and the band wheel connected with the shaft 71, but when the pin Z 011 the gear-wheel 2' strikes the end of the trip-lever m and throws the said upper end forward it disen gages the lower end thereof from the lever and allows it to rise so as to disconnect the band-wheel from the shaft and apply the brake.

The parts are so arranged and timed that when the pin acts on the trip-lever to disconnect the power from the shaft 72 and stop the movement of the mold and last carriers said last-carrier is at the forward extreme of its movement.

The operation of the machine is as follows: The operator places upon the last, for instance, on the right-hand side of the machine shown in Fig. 1, a boot or shoe the sole of which is to be beaten out or leveled and depresses the foot-leveron that side of the machine. \Vhen the said lever is depressed, the trip-lever m engages the lug thereon and holds the said lever down, and thereby causes the clutch mechanism to connect the band-wheel 7&3 with the shaft h. Then the worm-wheel is revolved three times, so as to reciprocate the last and mold carriers the same number of times. As this reciprocation is going on the operator is placing upon the other last 011 the left-hand side of the machine a boot or shoe the sole of which is to be leveled, and as he is about to depress the lever on the left-hand side to start the mechanism in motion .the wormwheel on the right-hand side of the machine has completed its three revolutions, so as to cause the stop in the pin 2' to engage the triplever and disconnect the power from the shaft h, whereupon the last is stopped at the extreme forward end of its motion. He then removes the boot from the last which has stopped moving and places another one upon it while the last and mold carriers are in this position. Thus it will be seen that the operator will just have sufficient time to place upon one last a boot or shoe while the sole is being leveled bythe other last and mold.

Vhile I have found that the sole is best beaten out when the carriers reciprocate the number of times set forth, it will be understood that I do not limit myself to having the mold and last carriers reciproeated three times before they are stopped, as they may be reciprocated any predetermined number of times, since the num ber of movements may be varied by changing the size of the wheel t. Nor do 1 limit myself to the devices which I have just described for reciprocating the lastcarrier rectilinearly or tangentially to the arc of movement of the moldcarrier, as this may be accomplished by a number of devices. In Fig. '7 I have shown mechanism for accomplishing this purpose which I prefer for some classes of work. In this figure the slide a is connected by a rod 01 with the upper end of a two-armed levern pivoted at 71 The lower end of the lever n is provided with a pin n projecting into a cam-track a which has three rises 2, 3, and t, respectively, and formed in a disk of, the rises 4 being considerably longer 'adially of the disks than the rises 2 and The disk n takes the place of the worm-wheel, and the mechanism is arranged to stop the radiation of the disk a when the pin a is in the outer end of the rise 4, so that the last is forced at the end of its movement to the extreme forward end of the machine and farther forward than it is during the other parts of its movement. Instead of employing the connecting-rod a for reciprocating the slide, it may be accomplished by means of a segmental rack 0, connected to the slide.

In Fig. 9 the last-carrier is pivoted to two links 13 p, the link 1) being connected by a pivot to a link p pivoted to a tie-1'odp ,tl1e

lower end of the link 19 being connected by links 19 p with another tie-rod or stationary pivot p and the said lower end is also provided with a roller or pin projecting into a horizontal slotted guide 29 19 indicates the pitman-rod pivoted to the link 19 and which oscillates the links 19 19' about their movable pivots, so as to cause the last-carrier to slide back and forth in the same plane.

In Fig. 10 the last-carrier is pivoted upon the upper ends of two links (1 g, having their lower ends pivoted to the cross-brace (1 resting upon an eccentric g keyed to the shaft q. The links q q are oscillated by the pitman-rod g and the shaft g is so timed that as the links are oscillated it raises and lowers them to compensate for their variation in the distance between the last-carrier and the cross-piece q, and thereby maintain the lastcarrier in the same horizontal plane throughout its reciprocation.

In Fig. 11 the last-carrier'is reciprocated b a screw-shaft r, passing loosely through the ends of the arms '1" 2", between which are held two loose pulleys 1' r and a pulley r internally threaded to receive the threads on the screw-shaft r. The pulleys r r are driven in opposite directions by belts 4" 0, respectively, and the said belts are shifted from the loose pulley to the fast pulley by devices operated by one of the movable parts. (Not herein shown.) The front end of the screwshaft is connected to the last-carrier by a pivoted link r so that the last-carrier may yield downwardly to permit the insertion of a thicker sole between the last and the mold.

In addition to the features pointed out I employ a guard,which is automatically moved adjacent to that set of carriers which is operating, to prevent the operator from getting any part of his person caught between this mold and last. It consists of a sleeve t, hav ing a wing or plate 75 and mounted loosely upon the rod a and held between two collars 6 The sleeve is provided with two arms i t, arranged on opposite sides thereof at an angle to each other and each adapted to be struck by a lug t or t on the last-carriers e 6.

By examining Fig. t it will be seen that when the slide or carrier 6 on the right-hand side of the machine has struck the arm t and thrown the guard in front of it, the other set of carriers being in a state of rest, the arm i is now in position to be struck by the lug t on the last-carrier on the left-hand side of the machine as soon as it starts to operate, and as in practice one set of carriers comes to a state of rest just before the other set begins its operation the set on the right-hand side of the machine will cease reciprocating before the slide or last-carrier begins its backward movement and swings the guard in front thereof.

Other changes may be made in the construction of the machine without departing from the spirit and scope of this invention, which comprehends a mold-carrier and a coacting last-carrier, one oscillated in an arc of a circle and the other reciprocating rectilinearly at a tangent to said arc, together with means for moving them simultaneously.

In combination, an oscillatory mold-carrier, a coacting last-carrier and means for causing their actuation to level a sole, said last-carrier being mounted to yield only in parallel lines at right angles to the tangential plane of the are of movement of the mold-carrier whereby the sole on the last is properly positioned against the mold, irrespective of its thickness.
