Application fled April it,

v is invention relates to shoe sole applying machines and has especial relation to machines tor securing soles tn shoes hy the use oi cement.

u ohject oi the present invention is the provision out a mac t of the ahove character wherehy the upper and the sole are pressed together in a manner to force air outward item the center heyond the edges ot the sole, and

in than avoid pockets, and consequently more securely attach the sole in position.

Another ohject ot the inventio is the pro vision ot novel means tor provig a pneuntic support for e shoe during the sole attacg operation and tor holding said support in place so as to resist outward epreaeg movement, wherehy the sole will he held close contact with the upper throughout its entire area and e tormation ol air ochets hetween the sole and upper will thus e prevented.

ether ohject ol the invention is the provision ot a achine otthe ahove character which is simple in coruction, e ti cent in use, and hy means ot which a sole may he attached to a shoe in a relatively short time and with a amount ot lahor.

With the shove and other ohjiects in view, e invention further includes the tollowing novel teatures and details ot construction, tn

hereinafter more lully descrihed, illustrated in the accompanying drawings and pointed out in the appended clas.

Referring to the drawings in detail wherein like characters nit reterence denote corresponding parts, the reterence character 10 indicates the hase oi the machine which may he of suitahle size and shape and trom which rise spaced standards ll. These standards support a her 12 at their upper ends so that ibis her is spaced ahove and parallel with the ase.

Mounted upon the lease 10 are holders 1% which are designed tn receive a pneumatic supporting element or hag lit, the latter heing designed to suport the shoe while the sole is heing ap lied.

Any numer ot these holders 1% and hugs it may he provided, two heing shown, so that soles may he simultaneously applied to a pair ol shoes indicated at 15. The hags it are removahly positioned within the holders and tor this purpose, one end wall ltd ot each ot the holders is removahle. Headed studs lt' ertend "from the ends ot the holders and the removahle ends it are provided with spaced slots 19 which receive these headed studs.

'lhe hags it are preterahly made ol leather and are shaped to center suhstantially to the shape ot the holders. lnner ruhher hags or 'hladders l9 are positioned within the leather hags it and are adapted to he inflated through valves 90. The hags ll may he termed as shown in Figure 6 and laced as indicated at 21, so that they may he readily opened and closed and the hladders renewed when desired.

y reference to lFigure lot the drawings it will he seen that the corners or edges oil the hag are rounded and that the inner walls ot the holder 13 curve inwardly at their upper edges and prevent spreag ol the hag when pressure is applied to its upper surtace.

The relerence character 29 indicates a pressure arm, one oil which is provided lor each hag holden, flue end oi this pressure arm carries a memher 29 which is adapted to hear upon a last or tree 24. positioned within the shoe. 'lhreadedly engaging the other llti tltl

liti

end of the pressure arm 22 is a rod 25 whose lower end carries a pressure foot 26 which is adapted to bear upon the upper of the shoe. The upper end of the rod 25 is provided with a squared extremity 27 to be engaged by a suitable handle or tool.

Threadedly engaging the bar 12 are threaded shafts 28. One of these shafts is provided for each bag holder and their lower ends engage recesses or pockets 29 provided in the pressure arms 22. The upper ends of the shafts 28 are provided with squared portions 30 to be removably engaged by a hand wheel 31.

By operating the shafts 28, pressure may be applied to the shoe and as the latter is positioned upon the pneumatic supporting element or bag 14, pressure will be applied centrally of the shoe outward due to the fact that the walls of the bag holder 13 confine the bag and resist its spreading movement.

' This action will cause air between the upper and sole to be forced outward and thus eliminate the formation of air pockets.

Also mounted upon the base 10 between the standards 11 is a sole board or sheld 32, upon which the shoe sole may be placed while being roughened and prepared for cementing. A clamping screw 33 which is threadedly mounted in a bar 34 serves to clamp the shoe sole in place during this operation. The screw 33 is provided with a squared tool or wheel receiving portion 35, whereby the screw may be adjusted.

The invention is susceptible of various changes in its form, proportions and minor details of construction and the right is herein reserved to make such changes as properly fall within the scope of the appended claims.

Having described the invention what is claimed-is .1. In a shoe sole applying machine, a base, a bag holder mounted upon the base and including side and end walls, one of said walls being removable, a pneumatic bag removably located within the holder with the upper face of said bag exposed for engagement by the sole of a shoe, and means to apply downward pressure to the top of the shoe.

2. In a shoe sole applying machine, a base, a bag holder mounted upon the base and including side and end walls having their inner faces curved inwardly at their upper edges, one of said walls being removable, a pneumatic bag removably fitted within the holder and having itsupper face exposed for engagement with the sole of a shoe, and means to apply downward pressure to the top of the shoe.

3. In a shoe sole applying machine, a base, a bag holder mounted upon the base and including side and end walls having their inner faces curved inwardly at their upper edges, one of said walls being removable, a pneumatic bag removably fitted within the holder
