IMPROVEMENT IN MACHINES-FOR TRIMMING AND SETTING THE EDGES OF BOOTS AND SHOES.

Specification forming part of Letters Patent No.'124,744, dated March 19, 1872.

To all to whom these presents shall come:

Be it known that I, SAMUEL HORATIO HODGEs, of Lynn, in the county of Essex and Commonwealth of Massachusetts, have made aninvention of certain Improvements in Ma. chinery for Trimming and Setting the Edges of Boot and Shoe Soles 0r Heels; and do hereby declare the following to'be a full, clear, and exactdescription thereof, due reference being had to the accompanying drawing making part of this specification, and in which Figure 1 is a plan; Fig. 2, a side elevation; Fig. 3, a vertical section; and Fig. 4, a rear side view of the mechanism for actuating the heel and toe rest.

The subject of my present invention is a device for supporting a boot and shoe, and presenting it to the action of the trimming or burnishin g mechanism, such device being termed,

in machinery of this character, a jack. The

purpose of my present invention is to provide a jack of such construction that the boot may be applied thereto and removed very expeditiously, and also enable the position of such boot to be varied with respect to the trimming or burnishing tool, as occasion requires, in order not only that such tool shall be compelled to traverse the entire sole-edge, but to vary the transverse angle or slope of the latter. The portion of my present jack which grasps the boot and supports it in position while its sole is being trimmed or burnished consists of two horizontal posts or jaws, the longer of which is the toe-rest, and supports the toe of the boot, the other being the heel-rest, which enters a socket in the last, the two supports sliding to and fro on parallel guides affixed to the outer face of an upright disk, and so operated, each by a screw which passes through it, and is supported within such disk and provided with a beveled pinion driven by a beveled annular gear, that, by the revolution of such screws traveling in opposite directions, the jaws or supports are compelled to approach or depart from each other, and either clamp the boot firmly between them or release it when the sole is finished, the ringgear being revolved by means of an annulus which surrounds and is H secured to it, and which is-prov'ided at intertion in the arc of a circle of the clamping device last explained, and, in'so doing,vary the position of the soleedge with respect to the trimming-tool, in order that a greater or less slope in extreme cases may be given to the toeand-heel portion of the latter,as circumstances require, I mount the upright disk before named at its rear upon a segmental block, and unite beam being controlled by. anadjusting-screw in such manner as to vary the horizontal adjustment of the entire jack, with the exception of its standard, in order that, when desirable,

the slope of the entire surface of the sole-edge may be varied.

The drawin g accompanyingthis specification represents at A a curved standard, which is to be pivoted or swiveled to the carriage which supports itin the machine to which it belongs,

such standard terminating at top in avertical column, a. B represents a circular plate or disk, to the outside of which is applied a dovetailed spline or way, 0, upon which slide two,

horizontalblocks or jaws, D E, one of which, D, is formed to receive the toe of a boot in manner at once apparent to all shoe manufacturers, while the jaw E has a tenon, b, to enter a socket formed in the .last near its heel-end, each j aw being formed with an ear, 0, which enters a lateral orifice ,or slot, cl, created in the center of the disk. Upon the rear side of the disk B I dispose two twin-shaped screws, F or F,these screws being in longitudinal alignment with each other, and disposed one upon each side of the center of the disk, and supported in bearings or lips e 0 formed upon such disk, while each screw carries at its outer end a beveled pinion, f, which engages with a beveled annular gear, g, which is disposed alongside of them,

rrrcn.-

or recede from one another for the purposes before stated; and in order to readily rotate the annular gear g I inclose it within and securely attach it to an annular concentric cap-plate or angular band, h, which is' provided upon'its periphery with handles or knobs 11 t, &c.

Having thus seen the means provided for confining or jacking the boot, we will now explain the means of setting the jack at any vertical angle, in order that the slope of the toe-portion ofthe sole-edge, and alsoofthe heeledge, may be varied and determined at pleasure, it being understood that the play of the jaws or disk is in a path parallel to or in alignment with the longitudinal plane of the said jaws. To carry out this adjustment I affix to or form upon the inner side of the disk B a block or housing, G, and in this housing I form a segmental dovetailed or shelf groove, H, which encompasses a segmental male tenon or spline, I, formed upon the outer face of a block, J, such block being swiveled horizontally to a tilting or oscillating lever or beam K, which surmounts and is pivoted to the upper part of the column a. The vibration or partial rotation of the disk B and its jaws upon the block J enables the angle of the toe-rest to be varied as occasion requires; consequently the revolving cutter or burnisher, whose horizontal position is arbitrary, will reduce the edge of the toe-portion of the sole to an angle corresponding to that of the toe-rest. It will be observed however, that as this adjustment or movement of the toe-rest is only in a direction coincident with the common plane of the two jaws, and affects only the toe of the sole and the heel, it has no effect in a contrary direction, or upon the sides of the sole.

To obtain the necessary rotary motion in a vertical plane of the jack, or that portion of it comprisedinthe disk and its jaws and adjuncts, I pivot such disk to the lever K, as stated. This pivoting of the disk enables the boot to be turned about upon an axis, which permits thero- .tary cutter or burnisher to travel entirely or partially around the sole, as the said cutter or burnisher is permitted afree play ina vertical direction in order that it may follow the varying outline of said sole.

In order to vary the general vertical slope of the entire jack for the purpose of determining the slope of the side edges of the sole, and, in certain cases, where not much slope is required, of the toe and heel also, without resorting to the segmental dovetailed connection before named, I pivot or fulcrum the lever K horizontally to the column a, as before stated; and to control and adjust the position of this lever and of the jack I employ a vertical feedscrew, is, the upper part of which is swiveled to the rear end of such lever, while its lower end screws through a shelf or car, l, affixed to the column a, as shown in Fig. 3 of the drawmg.

When adjusted in the desired position the disk B and its jaws are to be clamped or fixed to the segmental block J by a clamp or set screw, or any other proper means.- By pivoting or swiveling the standard A to its supporting tablet or base I obtain a horizontal rotary or swinging motion of the boot-sole with respect to the cutting or burnishin g tool, which enables such tool to follow all the curvatures of the outline of said sole with respect to the upper.

With mechanism above described aboot may be jacked almost instantly, as a rapid movenieut is imparted to the jaws by means of the gear or rack g and pinions ff.

The compound or duplex adjustment of the jack is also a matter of great importance in machinery for trimming or setting edges of soles or heels.

My present jack will also be found valuable as a bench-jack, to which purpose it may be adapted with little change.

I do not confine myself to the dovetailed connection herein stated as a point of vibration of the jack, as this vibratory union of the clamping portion of the jack with the rotary portion thereof may be effected in various ways, such, for instance, as simply pivoting it to the block J.

Claims.

shoe, the two jaws D and E, operated by the screw and ring gear, as and for purposes stated.

3. In machinery for trimming and setting the edges of boots and shoes, I claim a jack provided with heel and toe rests, or supports arranged both to tilt together longitudinally for the purpose of varying the slope of the heel or of the toe portion of the sole-edge, and also to rotate on a horizontal axis at right angles with the plane of their rocking movement, in order to permit the tool to traverse the sole-edge, substantially as shown and set forth,

4.. In machinery, substantially such as described, I claim a jack in which the heel and toe rests arecombined with the means herein described, or the equivalent of the same, whereby a threefold adjustment of the jack is obtained-that is to say, a tilting or rocking motion in the direction of the length of the heel and toe rests; a rotation in avertical plane at right angles to the plane in which the said rocking movement takes place; and an oscillating or tilting motion of the jack bodily, to vary the slope of either the side edges of the sole, or of the toe and heel, or both, substantially as shown and set forth.

5. The combination of the herein-described jack with a supporting standard arranged to swing upon a vertical axis, substantially as and for the purposes set forth.

6. I also claim, in combination with the jack and its supporting standard, the: lever K pivoted to-said standard, and the vertical feedscrew is Working in swiveled or ball-sockets'atcached, respectively, to the lever and to the standard, siibstantially as herein shown and set forth. l
