Application filed December 22, 1927. semi No. 241,812.

This invention relates toshoe making inachinery. V I I V One method of applyingsoles tothe uppers of shoes is by cementing, and in order to e 5 ciently carry out this'met hod of manufacture it is necessary to press thesojle very firmly into place so that the cement interposed between the sole and the upper willbe of equal thickness to provide a strong bond. It isan object of this invention, thereforato provide a machine for-"efficiently r ling and pressing sole, this machine being 'an improvement of that disclosed in our en-pendingapplication, Serial No. 228,238, filed October 24,

a. r Another object of the invention is to provide a machine having a roller adapted to firmly ,press a shoe sole upon the shoe upper, said roller being concave soas to conform to the transverse curvature with which shoe lasts are ordinarily provided, with the result that even pressure may be applied to the shoe sole throughout its entire area. 7 p The invention possesses other objects and features of advantage some of which, with the foregoing, will be set forth iinthe following-description of the preferred form of our invention which is illustrated in the drawings-accompanying and forming part of the specification. It is to be understood that we do not limit ourselvesfto the showing made by the-said drawingsand description as we may adopt variations of the preferred form with in the scope of our invention as set forth in the claims. v I p 5 a. 1

Referring to the drawings wherein similar reference characters designate similar parts throughout: l p 1 isa side elevation of the press of ourginvention. v I p V r I Figure 2 is a front elevation of the press'of Figure 1. V 1 J I Figure 3 is a top plan view of the press, parts being broken-away to better reveal the stinctnre.

. The press of our invention comprises a base 1 having laterallyextendingfeet 2, pte-ferably at "each end, with apertures 3-thei'ethrough permitting rigid mounting of the deviceupon a' suit'able support.- A pair of up wardlfv 'itiidifi'fispaced lugs 6 and a pin 7 extending therethrough provide a pivotal mounting for a support 8 upon the upper end of which a last 9 is carried. Preferably the manner of mounting the last 9 upon the support 8 is such that the last 9 is interchangeable, permitting the accommodation of shoes of various sizes. The pivot pin 7 is arrange" in parallelism with the major axis of th'e base 1 so that a certain degree of pivotal movement of the support8 and the last 9 transversely of the base 1 is permitted. 3

A pairof lugs 11 extendlaterally rant la base 1 forward of the lugs 6 and havefthrea ed'therein at oppositeends pins 12 which provide 'a pivotal mounting foraframe 13 which is preferably U shaped sothattlie upper or? tion 14 which joins the twolegs 16 an e 17 provides a convenient grip;18 for reciprocation of the frame 13 longitudinally ofthe'base 1 about its pivotal mountings 1-2. A roller cage 21 is slidahle longitudinally of the frame 13 and has revolubly mounted therein a roller 22. The proportionate;size 'andarrangement of the parts are such jth at the roller 22 normally rests upon the upper surface pf thelast 9. A lever 23 is pivoted as at, 24 to theleg 17 of the frame 13 and a pawl 26 car; ried by the free'end of the lever 23 is adapted to engage a ratchet27 uponthe leg 16 of the frame 13 to adjustablv limit theupper movement of the lever 23. A spring 28 under eom- 'pression between the lever 23 and the roller cage21 urges the roller 22 downwards upon the last 9, it being understood that in ferdr to increase the pressnre of the -roller thereupon the lever 23 mav bedepressed seas t9 increase the compression ofithe spring It is customary in the shoe making art to utilize lasts which are provided with a conyex surface and preferably the roller '22 which .we employ is concave to conform to the convexity of the last, the purpose being to exert even pressure throughoi'it' the entire area of the sole so as to squeeze the cementbetweenthe sole and the shoe upper to a constant thickness/. a

5 An auxiliary table31 is carried by the base l through the expedient of a standard 32, slidable longitudinally of the base 1 land on which standard the table 31 mounted for vertical adiustment.v When thedesiired veg tical adjustment has been attained the tel) 31 may be locked upon the standard by clamping screw 33 z" and a clamping screw permitslocking the standard 32 in an admsted, position upon the basl. V p In the operation of our device a shoeupper is positioned upon the last 9. Cement s then applied to the upper and the sole positioned thereupon, it being understood that access to the last is permitted by swinging the frame i 18 until the roller 22 is supported upon the table 31. YVhen the shoe and sole are in readiness the frame 13 is swung upon its pivotal mounting so thatthe roller 22 presses upon the sole; and then by depressing the lever 23 the spring 28 may be suitably compressed to increase the pressure of the roller. Reciprocation of the frame 13 backwards and forwards will then produ e a rolling movement of the roller across the sole with the result that the sole will be eilicaciously pressed into position upon the upper. 1

The concavity of the roller 22 has been found to produce a much more efficient comenting of the sole on the upper because of the fact that a roller having parallel sides has been found to exert a large amount of pressure on the sole at its center but very little at its edges. If it should be desired to ex ert still more pressure on the edges the pivotal mounting 7 of the last 9 provides convenient means for so positioning the last that one of the lateral edges at a time may have the roller reciprocated there across so that a relatively heavy pressure may be applied to the sole at any selected area.
