UNITED STATES PATENT OFFICE.

FEED RICKS AND REGINALD BOYD WOODCOCK, OF LEICESTER, ENGLAND, ASSIGNORS- TO UNITED SHOE MACHINERY CORPORATION, OF RATERSON, NEW JERSEY, A COR- PORATION OF NEW JERSEY.

SHOE-PRESSING MACHINE.

Application filed April 16, 1925, Serial No. 23.670, and in Great Britain August 16, 1924.

This invention relates to shoe pressing machines and is disclosed and illustrated as embodied in a shoe sole leveling machine of the so-called direct-pressure type such as is shown, for example, in Letters Patent No. 1,359,507 ,granted on November 23, 1920, upon an application of Arthur E. Jeri-am and Joseph Gouldbourn, and No. l.6l5 869,gra nted on February 1, 1927, upon an application of Basil P. Cooper, although in various aspects the invention is not limited to application to machines of this type. It may be sated here that since the present problem is essentially a. problem of supporting a last to sustain a shoe on the last against the pressure of sole leveling or other pressing means. retcrence will be made hereinafter particularly o the last. but it will be understood that the llustrated supporting means provided by the invention may as shown, support the last through contact with the shoe on it.

It hasbeen found that wooden lasts of. the movable heel part type or more specifically of the hinge type. when used to support shoes in leveling machines, are sometin cs distorted or broken at the joint or hinge by the leveling machine pressure, thus damaging. the shoes being leveled on them. The problem of avoiding such damage has been broadly treated in the application of A. E. Headley, Ser. No. 234340, filed April 14. 1925, in which a practical solution has been disclosed in connection with a direct-pressure leveling machine.

It is an object of the present invention to provide a shoe pressing or leveling machine in which a last will be even more effectively supported against damage of the sort referred to than has been done heretofore, without sacrificing any of the advantageous characteristics of previous machines such as machines of the type disclosed in said patents and application. 7

With a view to the attainment of the above stated object, an important feature of the in vention consists in an improved levelingmachine organization in which a shoe on a last. such as a hinge last, is supported for the leveling operation by heel and forepart supporting means and an additional support between the heel and fore parts constructed and arranged to have freedom of movement laterally of the shoe. more efficiently to effect contact therewith irrespective of the shape or p0- sitron of the shoe. Preferably, and as shown, the additional supporting means is formed as two members engaging the shoe on'opposite sides and having freedom of movement laterally as stated to accommodate the shoe between them without disturbance of the distance between them.

Another feature of the invention consists in provision for relative adjustment of two members such as those above mentioned. wherebythey may be caused to approach or separate from each other. i

Another feature of the invention consists in a novel construction and arrangement permitting two supporting members to have freedom of angular movement in any direction relatively to the last, together with the provision of meansforreturning them to a definite position when they are inoperative. These and other features of the invention, comprising certain combinations and arrangements of parts, will be understood from p the following description of a preferred embodiment thereof selected for purposes of illustration and shown in the accompanying drawings in which, l

Fig. 1 is a view in side elevation of last supporting and leveling instrumentalities ineluding an embodiment-of the present invention in a machine of the type alluded to above. Fig. 2 is a rear elevation of the same parts.

As already stated, the illustrated machine is of the type shown in the patents referred to, to which reference may be had for more detailed description of theconstruction, arrangement and operation of parts not fully described herein. The leveling form 52 is shown herein only diagrammatically. Its

tailed way 2** to accommodate difierent lengths of shoes similarly to the heelend suplength by a rod 1-? which passes through a port 3, as described in "the Cooper patent abovereferredto. The shoe B. on itsilast C is shown supported on these supports as described in the Cooper patent.

Secured to opposite sides of the base of the heel end support 3 (so as to move therewith as the latter is adjusted on its slideway 4:) are short brackets leach carrying one of two parallel pivot pins 15 the axes of which are inclined forwardly and upwardly so as to be parallel to the heel end support slideway. Pivoted on the pins 15 andprojecting upwardly so asto extend on either side of a last carried by the forepart and heel end supports are a pair of arms 16 connected together at a point about "half way of their pivoted trunnion bearing,.18 in each arm. The opposite ends of the rod 17 are provided with right and lefthand threads 19, 20, which engage with similar threadszon the respective pivoted trunnion bearings.

Rotation of the rod 17 will therefore cause the upper ends of the arms16 to approach or separate. from each other, while the rod does not interfere with swinging movements of the arms about the pivotal bearings at 15.

The upper end of each-armlG terminates in a ball- 30 forming aspherical seating or universal mounting for a felt-covered flat metal holding member or block 31. These blocks contact with the shoe at the desired locality, one on'each side, and effect the desired support in the regionof the joint between the last parts. A pin 21- screwed into each of the metalhlocks 31 passes into a bore 22 of large diameter drilled in the arm 16 diametrically of the ball 30 and is engaged by a tension spring 23 secured at its lower end to a transverse pin24 at the lower end of the bore 22. It will be apparent, therefore, that although the felt-covered blocks 31 can, on engagement with a shoe, turn in any direction about their spherical seatings to engage the shoe firmly over their whole surface, they will when released from engagement, with the shoe be returned to their original inoperative'position by the springs 23. I

Since the arms 16 are pivoted at 15 to fixed supports and are only connected by therod 17 passing through-their, trunnions, they can swing together about their pivots in either direction, andare constrained to swing both in the same direction, and thus carry the feltcovered blocks3l in company laterally of their mid positionso thatthese mayeonjointly locate. themselves. in :receiving the shoe. 3 Studs 25 passing through bosses 26 on the lower ends of the arms l6 contact with stops 2'? .on the brackets 14, to limit the'extent to which the arms can thus swing. 1

,A felt-lined metal band 28 mounted on arms 32 secured to the base of the heel end support by flanges 34 slotted at 36 to permit adjustment is shown in Figs. 1 and 2 extending around the heel end .of the shoe upper. This band prevents rearward displacement of the shoe during the operation disclosed in the Cooper patent aforesaid, but in this iustance the arms 32 are bowed out on each side to allow the machine operator to get his hands in easily, from the rear of the boot, to pull uponthe upper of a boot to position it as shown.
