ing the heels of shoes and it consists in constructions, arrangements and combinations herein described and claimed.

The heels of shoes often require sanding or leveling before leather liftsiorg' rubber heels can be applied, and'this"in the'past has been accomplished manually with no.,certainty that each heel of a'pair ofshoes'willhave the right angular relation with respect to. the soleof the shoes.

It is therefore an "import" tkobject or the inventi'cn to provide a" machine in whicha support is empldyeda'djustable' with respect to a grinding or sanding disk, the adjusting means including a locking means for maintaining an adjusted position, thereby insuring a like sanding or grinding of each shoe of a pair.

It is also an object of the invention to provide a novel and simple gauge means including a slidable spring-urged plate, the outer free end having a shoe support enabling proper "alignment between the heel and the sole of a shoe and further including locking means for securing the plate in an adjusted position.

Additional objects, advantages and features of invention will be apparent from the following description and accompanying drawings, wherein Figure 1 is a side elevation of the machine with a shoe in position for grinding or sanding.

Figure 2 is an end elevation thereof.

Figure 3 is a top plan view of the bed of. the machine,

Figure 4 is a side elevation thereof.

Figure 5 is an end elevation thereof.

Figure 6 is a top plan view of the gauge and shoe support device detached.

Figure 7 is a side view thereof.

Figure 8 is an end view of the support.

Figure 9 illustrates a plan and edge view respectively, of a closure plate for securing the gauge and support within the bed of the machine.

Figure 10 is a top plan view of the locking means for securing the gauge and support in adjusted positions.

Figure 11 is a top plan view thereof.

There is illustrated a sanding or grinding machine consisting of a casting substantially of rectangular shape in plan, having a planiform bed base I I from which there are extended right angular end walls l2 and [3.

As may be seen in Figures 3 and of the drawings, the bed H is formed with a pair of guideways 14 and I5, extending longitudinally of the bed the full length thereof and being positioned medially of the bed, The guide-way M is formed 2 Claims.

The lotlfl ount r: snag to accommodate 3 headjlloi abplt 2| for securing'the pla imposition ,within the slot. .By looseningthe boltl 2t itj wiil be apparent that the plate Iii avbe,-n'roved ,longitudinally of the The plate ,IB is formed with a tongue 22 of a width less than that of the plate proper defining respective shoulders 23. The plate I! is bifur-F cated, forming a slot 24 of a width to slidably engage the tongue 22, the legs 25 thus formed being aligned with respective shoulders 23 and between each of the opposed shoulders and the ends ofthe legs a helical spring 26 is interposed. The springs 26 function to project the plate I! beyond the outer edge of the slot 14 and the end plate l2, as shown in Figure 1.

A heel rest 21 is secured upon the outer end of the plate I1, in the present instance the rest being shown as a yoke member 28 bolted or otherwise secured to the plate and extending upwardly at right angles thereto. The arms 29 of the yoke mounts a rod 30 upon which a heel may be rested for sanding or grinding, as will be described hereinafter.

With the plates l6 and I1 assembled and disposed within the guide-way [4, a closure plate 3| is positioned in the guide-way I5 and secured by means of machine screws 32 adapted to engage threaded openings 33 in the guide-way Hi,

It will be necessary to provide a lock means for securing adjustment of the plate l1, and as here shown, a threaded aperture 34 is provided in the guide-way l4 into which a screw 35 is engaged the screw 35 including a head 36 oscillatable by means of a handle 31 of a length so as to extend beyond the edge of the casting for ready manipulation. The screw 35 is adapted to impinge upon the lower side of the plate when the head is rotated in one direction, but readily retracted when rotated in the opposite direction for release of the plate.

The casting is provided with suitably spaced openings 38 for rigid mounting of a motor 39, the

latter being centrally located so as to present the griding or sanding disk in alignment with the end plate l2.

In use, with the locking device in released position, the plate l'l together with the rest 21 will be in its outermost projected position, a shoe is brought to rest upon the rod 30 and a rearward movement is imparted upon the shoe in the direction of the disk 40, until the sole of the shoe contacts the end wall l2 and the heel rests against the disk. The handle 31 is grasped and rotated so as to turn the screw 35 into impingement upon the plate I! and the adjustment is secured. The motor 39 is now started to surface the heel and when this is accomplished the other shoe is similarly treated with assurance that both heels will be of the same height and of like bevel.

It will be apparent that the rest 21 can be quickly adjusted to another pair of shoes by merely actuating the handle 31 to release the plate I! which will be urged outwardl by reason of the springs 26 and the adjustment of theshoes with respect to the disk 40 and theendfplate' l2 re peated. V

While I have shown and described a preferred form of the device, thisis by way of illustration only, and I consider as myown all suchmodiflcations in'construction as fairly "fall'withinthe scope of the appended claims.

Iclaimf 1. A heelsurfacing device comprising a base, said base having a pair oflguide-ways arranged in superposed relation, the lower guide way being of narrower width, a' plate adjustably fixed in said last named guide way, said-plate having a forwardly extended tongue, a second plate in said "guideway in advance'oi' the first plate and having an open ended slot for receiving said tongue therein, spring means between adjacent ends of said plates urging said named plate outwardly of said guide way, means for locking said second named plate in an adjusted position, against the tension of said spring means, a driven grinding disk mounted upon said base, the latter including respective end walls one of which is in vertical alignment with the outer face of the grinding disk, and a heel support carried on the outer end of the second named plate adapted to position a heel of a shoe against the grinding disk and the ball portion of the sole of a shoe against the adjacent end wall of the base.

2. The structure 01' claim 1 in which the locking ir'ieans comprises a stud threaded through the lower wallof the lower guide way for impinging "the second named plate and a. lever'connected to saidstudfrorrotating the same.
