FORM Fon is'oo'rs AND SHOES.

Patented Ang'. 2, 1910.

Application filed May 2G, 1904. Serial No. 209,947.

To all whom. it may concern:

Be 1t 1lnovvnthat I, MATTHIAS BROCK, a

citizen of the United States, residing at Boa.`

ton, inthe county/of Suifolloand Common'-,y Wealth of Massachusetts, have invented certain Improvements in Forms for Boots and Slices, of which the following description, in connection With-the accompanying drawings, isa specitication,like reference characters on the drawings indicatingr like parts in the several figures.

This invention relateslto a` device for tilling out a boot or shoe and more particularly to a device adapted for use'either as a fol lower, during the finishing operations in the manufacture of the shoe, or as a form or tree, by which the shape of the finished shoe may be preserved or restored. Shoes which have lost their shape through wear or dampness may be readily resl'iaped by meanslof such a form. Devices embodying the invention are also welladapted for use as display forms by means of which shoes may be exhibited to advantage. It may be employed in polishing slices, or, indeed, for

any other use where it is desired to fill out and support a shoe while some light operation is being performedupon it.

In order to avoid rg-ipetition in the further description of my. invention I will refer to a device embodying my invention as a form.7 Such a device is known in the art variously as a form, a tree, a follower, or a last, but it is obvious J[hat I intend to in 'elude by this word form any device for filling out a shoe of the character above set forth by whatever term it may be described. Similarly, the term shoe is used generally to include boot, shoe, slipper or other similar foot covering.

In the preferred embodiment of my iuvention I make my form in a plurality of sections, Which may be contracted to allow ready insertion into a shoe and then hc eX pandcd to fill it out and give it the proper shape. I provide, therefore, a longitudinally divided or split forepart .and a heel-part which is also preferably, but not necessarily, divided longitudinally. By having both the parts exp'ansible, the form fillsout both the heel and/the forepart of the shoe to give the Whole shoe itsproper shape.

An. important feature of my invention is that the forepart is made to move bodily,

relatively tothe heel-part, in substantially a straight line longitudinally. With such construction, after the shoe has been given its proper shape there is no danger of stretching it againout of this shape during the Withdrawal of the form from the shoe,

for the form is so much shortened When' contracted that it may be Withdrawn freely vyithout pressing against the back of the sioe.

Another feature of 4importance is the means for separating the sections of the form laterally. It is desirable that the form, When expanded to operative position Within a shoe, shall be of a definite Width, and therefore the means for separating the sections should act ositively Without yielding. In the form em odying the present invention the Width of the expanded form is predetermined and the upper will not be forced beyond its proper place relative to the edge of the outer sole, even when the leather is wet and capable of being stretched easily. The mechanism which I employ sepa-rates the `sections of the form a` distance which does n ot depend upon the condition or character of the material of the shoe. In the embodiment of my invention illustrated, I place a toggle between the sections which is connected to the fore and heel parts and also located to cooperate with a wedge, cam or cam lug in one of the sections in such a manner that, by the straightening of the toggle, the form is expanded simultaneously both longitudinally and laterally. In order to provide for adjustment I preferably make the forepart yieldingly movable, relatively to the heel-part, so that the form may accommodate itself to slight vai'iations in the lengths of different slices. I have also shown means, such as a screw, to adjust the Wedge or cam lug to vary the width of the form in its expanded position. 4

My form is compact and may be coii v en iently packed with no parts projecting and liable to injury. To this end, a recess is made in the heel-part to receive the knob or hand piece usually provided uponv the operating toggle. 'Hence when the form is inserted and expanded in a bal shoe there r is no handle projecting into sight,

Other features of the invention, including various combinations of parts and details offconstruction, will now be described in connection with the accompanying dra-W- ings forming part of this specification. My

invention, however, is manifestly not limited to these specilic details, but its scope and essential features will be clearly set out in the appended claims.

tefe'fring now to the drawings, which show a preferred embodiment of my invention: Figure 1 is a side elevation pt the Jiorm With one half removed, the pivot block being shown in section. Tl-e parts are illustrated in their contracted position, in which position the form may be inserted readily into a shoe, the shoe being iinlicated by dash lines; Fig. 2 is a side elevation of the complete form in operative position filling out the shoe, the springs in the .fore'part being somewhat compressed; Fig. 3 is a plan view of Fig. 2 with the springs released and the forepart eut away to show the pivot block; and Fig. 4 is a transverse section of the complete form on line 4 4 of Fig. l.

As illustrated, my form comprises a forepart 2 and a heel-part 3 movable on guide pins Lt and et toward and from each other in substantially a straight line. The forc part is composed of two sections 2 and 2, and the heel-part of corresponding sections .3 and 3, the sections of each part-being movable toward and from each other in substantially straight lines upon guide pins 5. It is not essential that the heel-part be divided, although such construction is preferable in order that the heel of the shoe, as

well as the toe, may be kept in shape.

lVhere the heel-part is made 1n one piece, the pin 4t is received in a slot in either the heel-part or the forepart to permit the lateral movement ol section 2 relative to section 2.

- The mechanism for expanding the form comprises a' toggle made up of two levers 6 and 7 pivoted at 8, the lever t3 being extended backwardly and provided at its rear, upwardly-turned end with -a knob or handpiece 9, as shown. The lever 7 is pivoted to the heel-part upon one of the guide pins 5 while lever (3 may be connected at its front end to a similar fixed pivot. l prefer, however, ,to make one of these pivots yielding, so that the form may be adjustable according to the length of the shoe. Hence, in practice, l mount lever 6 upon pivot 10 in a slot in a block 1l. This pivot block is adapted to move longitudinally in recesses 12 and 12 in the forepart sections, but is normally pressed rearwardly by springs 13 and 13. Projecting pins 14 and 15 may be located on the block 11 and at the forward ends of recesses 12 and 12 to positively retain the ends of the springs in pla-ce,- but these pins are not essential. Also, one spring only `l'or the p1vot block may be of.

sufficient strength, in which case the spring.

13 may be dispensed with. Nevertheless, when this spring 13 is used it readily bends, as shown in llig. 3, to allow the lat.;

eral separation of tliii'forepart sections. It. will be noted that the toggle is connected to the forepart toward its vforward end and that the pivots 5 and l() are in a line eXtending longitudinally ot the torni approximately parallel to the line in which the heelpart moves with reference to the torepart as the form is contracted or expanded. By such construction there is little tendency of the parts et the t'orm to bind upon the guide pins 4, Ll.

Obviously, by the depression ot the toggle, in the construction so t'ar described, the torepart and the heel-part are separated longitudinally in a straightline with a yielding pressure. Preferably, however, l provide, also, means for simultaneously separating the sections laterally. Near the longitudinal center of the form the foregoing sections are provided with recesses 16 and 16". A Wedge or cam lug lits into recess 1G and is adapted to eoperate with the toggle to separate the sections. Assuming the form to be in its contracted position (Figs. 1 and 4),.as the toggle is straightened the lever (l travels down the wedge 17. Since the toggle bears against the inside of sections 2 and 3 the other sections 2 and 3 are forced laterally therefrom` by the action of the wedge, to the position shown in Fig. 3. Therefore the depression oit' the toggle to, or just beyond, its dead center position expands the form longitudinally with a yielding pressure and, at the same time, expands it laterally with' a posit-ive pressure. The toggle then holds the form in its expanded or open' ative position'. .its indicated in Fig. 1, the wedge 17 may be curved longitudinally so as to have the forni ot an are ot a circle whose center is the pivot pointI 10 when approximately at a mean position. Thus there is comparatively little longitudinal travel of the leverY 6 relatively to the wedge 17. The elt'ect would be nearly the same if the wedge 17 and its recess 16 were made straight and inclined so as to have the form of the chord of the circle corresponding to the are shown. The recess 16 may be of any shape suitable to receive the wedge in the contracted position of the form.

The drawings show means for ad'usting the wedge 17 whereby the extreme width of the form when expanded may be varied. A rectangular nut 18 is countersunk in a recess hack of recess 16". Screw 19, threaded through this nut,bears at its end upon wedge 17. By turning the screw, the position of the wedge may be. changed from that shown in Fig. 4, by full lines to that shown by dotted lines; or to any intermediate 'iositiolr If desired the upper end ot' the wedge may be pivoted in its recess 16 upon a transverse pin.l [u practice, however, this is uuncccssary since the wedge is' made to (it snugly 'in its recess and lhe't'orce exerted by iis tial, and Where a cheaper form or follower is desired the wedge may be fixed in position.

Instead ,of the screw 19, or between it and the wedge 17, I might insert a spring in any convenient manner, but, for the reasons above stated, I prefer to separate the seo tions with `a positive pressure and to a predetermined Width, and therefore do not ordinarily use such a spring.

l lln addition to the'single Wedge in the forepart, a second wedge, to cooperate with lever 7, may be placed in heel-part section 3.

My invention is not limited to a heel-part which is separable from the forepart, for the heel-part may be niaderin sections integral with t-he corresponding forepart sec tions, or it may be dispensed with entirely. In the lat-ter case, the rear lever 7 of the toggle, being then unnecessary, would beA omitted also, but the pivoted front lever 6 Would spread the forepart sections by cooperating with Wedge 17, as in the construction illustrated.

In order that the forepart sections maycome into contact and present an unbroken top surface in their contracted position I recess the sections slightly, as shown at 20,

leaving bearing ribs along the top edges, as

shown in Figs. l and 4. n The heel sections are similarly recessed. In this way space is provided for the toggle levers when t-he laterally movable sections are brought together.

The heel sections are shown as provided with a hole or recess 2l in which the lower part of the knob 9 is seated when the form is expanded. This gives a neat appearance to the form and makes it compact and convenient for packing.

In the above description I have set forth many details which are not essential parts ol my invention.: Some. of the novel features may be embodied in. -a form in which i other features herein described are omitted.

It is therefore obvious that many modilications oiz the construction shown may be made which would be' clearly Within the scope and spirit of my invention. n
