- This invention relates to a machine for use in cementing soles or half soleson shoes, particularly in connection with repair operations.- I

It is the object of my invention toprov-ide a machine for such purposes by which a shoe and to'a bracket 22 slidable on a cross bar 23, which a cement-coated sole may be very quickly and conveniently placed under pressure and by which the pressure may be maintained for any desired period. i a 3 A further object of the invention istoprovide a machine for suchpurposes so designed that it is readily adaptable for use on shoes of widely differing shapes and sizes and for either whole l sole or half-sole operations. a

I have also provided improved devices iorhold ing and-supporting the shoe during. {the pressing operation. l

A I a A bell crank or handle 32-is provided for each pressing device and is pivoted on a-stud 33 mounted in bearings 34 on the under side of the top.

I 4, which is .cess l3 and against the recessed base member I0.

' When thehandle'32 'is substantially in horizontal position; the lower portion of the handle and the associated links 35 act as togg1e mem-v hers to hold the shoe supports and shoe positively. in the lowered position indicated in :Fig. 6. Each sleeveis preferably provided with transverse openings 40 and each plunger 31 is provided with a corresponding transverse opening in which balls 41 are mounted and are pressed When a sleeve30 isfiinoved to-raised position,

the balls fll enter the openings 40 in the sleeve ated parts in raised "position until the handle 32 1s againswung forcibly downward.

30 and releasably retain the sleeveand associa The machine maybe adapted for use on shoes of differentlengths by sliding-the br-acketi22. along theycro'ss bar 23 to? a position where the shoev is the recess 1 3 in the base! 0, after. which the back or heel support .28 is moved toutwjard toward the dotted l'ineposition in Fig.-2".until the heel of againsttheiront support 20.. 1

The front support 20 may be adapted to shoes having different shaped toe portions by providing aseparate toe piece 56 having a rib and slot connection to the front end of the support 20, so that one toe piece 50 may be removed and another toe piece of difierent outline may be substituted, such a substituted toe piece being indicated at 58 in Fig. 3.

The front shoe support 20 may also be made in two parts land 52 (Fig. 3), theseparts being separable longitudinally and one part being provided with a lug or lateral projection 53 (Figs. 2 and 3) extending into a recess 54 in the other part and secured in adjusted position'by a clamping screw 55.

With this construction, the support}!!! may 'be widened or narrowed to fit different shoes and the toe portion may be adapted to different wardly extended portion 6| of the support 20.

This overlapping feature permits a much wider range of relative adjustment of the back support 28 and also provides asufficiently continuous surface for the shank portion of the shoe.

Forhalf-sole operations, the frontsupportiil may be used alone as indicated in Fig. 9, the back support 25 being removed. By adjusting the screw 26 in the lower end of the sleeve 30, any desired final pressure may be secured.

When the shoeis in the pressing position indicatedin Fig. 6, the rubber cushion i4 snugly engages the shoe sole or half-sole at all exterior portions thereof and forces the same firmly against the sole ofthe shoe, in which position the sole is retained during the drying and setting of the cement. V

The sole-shaped depressions iii in the bottom of the recess I3 substantially assist the operation by providing exceptionally heavy pressure around the edge portionsof the sole where firm contact and a tight joint is particularly essential.

.An important advantage of my improved pressing machine lies in the fact that no last is used and that no pressure is applied .to the shoe upper at any point, as has been the custom in machines previously used for this purpose. The app1ica tionof pressure to the shoe upper quite commonly results in injury to, the shoe, particularly toladies shoes formed of light or easily defaced materials. I

In the operation of cementing soles to shoes, particularly for repair purposes, it is necessary to place the cemented parts under pressure with the least possible delay if a firm and tight joint is to'be attained. Reference to the drawings will show that my improved. machine is particularly adapted for such rapid operation, as the front shoe support 29 .may be adjusted in position before the shoe parts are cemented and the ad justment of the heel support 28 and downward movement of the lever 32 may be performed almost simultaneously and with great rapidity. r While I have shown my improved machine in duplex form, so: that a pair of shoesmay be conveniently cemented and pressed at the same time, it will be obvious that a singlepressing' device may be made embodying my improvements.

Having thus described my invention and the advantagesthereof, I do not wish to be limited to the details herein disclosed, otherwise than as set forth in the claims, but what I claim is:

1.

' 2; In a machin'e for pressing shoe soles, in combination, a vertically movable member, a cross bar pivoted thereto on an axis transverse of said bar, a bracket slidable thereon, means to secure saidbracket in adjusted position," and 'a front sole-engaging shoe support pivoted to said bracket.

3; In a machine for pressing shoe soles, in combination, a vertically movable member, a cross bar pivoted thereto on an axis transverse of said bar, front and back sole-engaging shoe supports mounted to slide relative, to said cross bar, and means to secure said supports in adjusted position. Y I

4. In a machine for pressing shoe soles, in combination, a vertically movable member, a cross bar mounted thereon, front and back shoe supports mounted to slide relative to said cross bar, and means to secure said supports in adjusted position, said supports having overlappingportions permitting extended relative longitudinal adjustment while maintaining engagement thereof.

7. In a machine for pressing shoe soles, in combination, a vertically movable member, a cross bar pivoted thereto, a bracket slidable thereon, means to secure said bracket in adjusted position, and a front sole-engaging shoe support pivoted to said bracket, said front shoe'support having a removable and replaceable toe piece detachably mounted at the front end thereof and having a rib and slot connection thereto.

,8. In a. machine for pressing shoe soles, in combination, a vertically movable member, a cross bar pivoted thereto, a bracket slidable thereon, means to secure said bracket in adjusted position, and-a frontshoe support pivoted to said bracket, said shoe support being shaped to substantially conform to the front and shank pore tions of a shoe mounted thereon.
