TOE-FORMING MAGHiNE,

St; Paul, in the county of Ramsey and State :of' Minnesota, have invented a new 1anduseful Improvement in Toe-Forming Machines, of which theffollowing is aspecifi v in a circlearound the shaft. Thus all of cation.

2 An object of this invention is the produc{ tion of a machine for rolling out and smoothing leather in finished condition on the toes of shoes during the process ,or, manufacture after" the shoes have :been lasted and prior to finseaming. Primarily said invention is applicable to shoes of that class generally known as Goodyear welt;

7 Previous to my invention, ithas been cus-v tomary to smooth out the wrinkles by.

Y pounding or rubbing the leatheron the last by hand, whereas by the use of mymven tion the leather is smoothed evenly and quickly by machine rolling with less hand labor andexpensethan heretofore, and with improved results. This rolling-operation occurs previous to the inseaming or welting' operatlon, and 1s designed to prevent Wllitt' is'known in the art as grinning of the seam around the toe. The machme is also useful for rollingand removing wrinkles from or other materials of any form.

the counter toward the heel seat and when made of proper dimensions and slightly modified can be used for rolling out leather In the accompanying drawings forming part of this specification, Figure 1 is aside elevation partly broken away and in section, and Fig. 3 is a plan of two of the rollers employed in the machine;

'A" indicates a shaft suitably jou rnaled upon a base B and carrying tight and loose pulleys2. and 3, by one of which the shaft is actuated. The end of'theshaftopposite that onwhich the. pulleys are mounted projects from journal boxes 4' and 5 formed integral with the, base and carries a'spool 1 6, the body of which is secured to the shaft fastened by screws 9' to circular-roller su by key 6", (see Fig.-2). The opposite ends 7 and 8e of this, spool are respectively Specification of Letters Patent.

theoil openings 18 leading into bearings 15 a l with a radial plate 19, the periphery of;

which is concentric with the axis of the shaft A and to said periphery an internal gear 20 is secured, said gear being formed :with a shoulder 2t spacedfrom said plate 19 and with a collar 22, the latterbeing fastened .to said peripherymbyscrews 23.

The'space bounded byythe shoulder 21, the

inner faoeiof' the radiahplate l9 and the innersurface of collar 22 forms a circular channel in which the roller supporting plate 11 is freely journaled so thatjthe latter may be revolved by the shaft A with little fric- 'tion and with littleornolubrication; The

teeth of the internal gear "20 face inwardly and are of suilicient length to engage the teeth oftwo rows of pinions 24 and 25 which are shrunk i or otherwise secured to the gudgeons iron the ends of the rubbing rollers-l2. The pinions 24 are alternately positioned lengthwise upon the gudgeons 14:, 7 in other words the pinion on each succeed-1 ing rubbing roller is placed in line to *as' sumeta posit on n one or the vother of the series of pinions, so that pinions of greater outside diameter than that of each rub- I bing roller may be employed to mesh with the teeth of the internalgear. .Thegroup of shaping or rubbing rollersand thelr sup:

ports produce a spindle and each time this; spindle revolves, every rubbing roller has contact between the peripheries of the rollers and the material being formedwhich is an advantage, a rubb ng contact being highly objectionable because'it causes burning, bruising and uneven stretching of the material. Oil or other lubrication may be applied to the internal gear by the'oil cup 26. The inner edges facing each other of the end plate 10. and the internal gear 20 are formed with inwardly projecting illturned guards 21 and 22-, the faces of which are curved to prevent abrasion of thesurface ofthe shoe by contact therewith.

At one side of the device in suitable posi-.

tion to support the toe of theshoe, so that its surface may be rolled by the peripheries of the rollers is a suitable rest C of any convenient form, that illustrated beingof ordinary construction. This rest has a circular plate rest 26, the surface of which is knurled and adapted to receive and hold the lower portion of the toe of the shoe. This plateis journaled upon ascrew 27, and is carried by a horizontally ournaled support 28 in a yoke 29 formed on the upper end of the arm 30. A spring 3l'holds the support28 with its rest plate 26in forwardly inclined position normally against. the stop 31. The

lower end of the arm 30 is mounted upon and secured to a shaft 32, which is journaled upon the bracket 33 formed 011 the base of r the machine. A collar 34 is secured rigidly to the shaft 32 and has secured to its periphery a draw spring 35, which is anchored to an arm 36 extending hackwardly from the bracket 33. This spring yieldingly holds the arm 30 in upright position against the stop shoulder 37. In this manner the toe of the shoe may be placed on the rest plate 26, and

moved backwardly and tilted at any angle required so that the surface .of the toe may be applied against the revolving rollers 12 and the wrinkles in the latter quickly and effectively smoothed out, producing finished work. The rollers being positively driven while the spindle is revolved serves to grad ually and quickly draw and form the leather on a regular curve without abrading or wrinkling the material.

In accordance with the patent statutes, I have described the principles of operation of my invention together with the apparatus which I now considerto represent the best embodiment thereof, but I desire to have it understood that the construction shown is only illustrative and that the invention can becarried out by other means and applied to uses other than those above set forth within the scope of the following claims.

Having described my invention, what I claim as new and desire to protect by Let ters Patent is 1. A toe forming machine, CODSlStlllg of a revoluble spindle having a plurality of.

shaping rollers journaled freely therein, said rollers. being arranged longitudinally parallel with the axis of said spindle and in a circle co-axial therewith, and means to produce revolution of each of said rollers in its journal interdependent with the revolution of said spindle.

, 2. A toe forming machine, comprising, in

combination, a drive shaft, a spindle mounted upon said shaft and'adaptedto revolve therewith, and a stationary internal gear co axial with said shaft, said spindlehaving a plurality of rollers longitudinally parallel with and arranged in a cluster co-axially about said shaft, 'said rollers having drive pinions, the teeth of which mesh with the teeth of said internal gear, whereby as said spindle is revolved, said rollers turn with said spindle and have imparted to them a surface speed producing rolling contact against the material being formed. 7

3. A machine for smoothing leather, comprising in combination, a main revoluble element, a plurality of subordinate elements carried by said main element, and

means for imparting motion to said subordinate elements, whereby they have motion interdependent with the motion of said main element and friction upon thematerial being smoothed is reduced.

4; In a machine for smoothing leather, a main revoluble element, a plurality of rubbing rollers journaled freely and arranged in circumferential allnement and co-aXial with sa1d revoluble element, an internal gear about said series of rollers, and a pinion carried by each of said rollers with its teeth meshing with the teethof said internal gear, whereby as said main revoluble element revolves, each of said rollers is revolved upon its own axis, and all of said rollers are moved around the axis of said main revoluble element.

5. A machine for smoothing leather, comprising, in combination, a main revoluble element, a plurality of rollers carried by said main element having drive pinions, and a revolve, the pitch diameter of each of'said stationary g'eai' With the teeth of which the In 'testimony whereof, I have signed my teeth *of said pinion mesh to cause them to two subscribingwitnesses.
