heel has its marginal portions respectively and a heel breast covering two grooves.

above-mentioned has its marginal portions respectively also tucked into these It is an object of the present invention to provide a machine for buffing the exposed surface of the heel breast cover of heel of the type above referred to without damaging the marginal portions of the covering for the side and rear surfaces of the heel.

In accordance with this object, one feature of the invention consists in providing a rotaryguide wheel in cooperation with a buffing member to retain a shoe in such relation to the butfing member as to prevent undesired contact of certain portions of the heel with thebufling member while the heel breast is being buffed. In the illustrated tucked into two grooves machine the bufiing. member consists of a plurality of members composed of sandpaper having rounded corners, which membets are secured in slots respectively in a spindle in such a manner as to enable the sandpaper to. adapt itself to follow the irregular contour of the work.

These and other features of the invention willbe more fully described and pointed out in the accompanying specification and drawings, in which, y I Fig. 1 represents a perspective viewof the shoe provided with wooden Louis heels hereinabove mentio-ned;.

Fig. 5 represents an end View of the spindle of the machine shown in Fig. 3, and the method of mounting the flying sandpaper for. butting the heel breast Fig. 6 represents a plan view of the heel with top lift removed, and illustrates the relation of the guide which operates in one of the recesses of the heel breast of the shoe shown in Fig. 1; and

Fig. 7 represents a modification of the spindle and an alternative means for mounting the sandpaper for bufiing the heel breast which is mounted in said spindle.

Referring more particularly to Fig. 1, 1 represents the wooden Louis heel of the shoe, 2 represents the heel top-lift thereof, 3 and 3 represent the recesses into which are tucked both the heel covering a and the breast flap b which extends from the sole covering 0 of the shoe.

In Fig. 3, 4 represents a suitable foundation upon which is bolted the bed plate 5 of a pedestal 6 of our improved buffing machine. The shaft 7 is mounted in suitable bearings 8 and 8, and in this shaft is carried a spindle 9 having a tapered end 10 which fits into an opening of the shaft 7 and is held therein by a set screw or pin .31. At a suitable distance from the outer end of the spindle 9, and forming a part of saidspindle, is an enlarged tapered shoulder 18. 13 represents a loose collar having a tapered mouth fitting the tapered shoulder 18 of spindle 9. Opposite the tapered end of collar 13 is a collar 11 which is threaded on the shaft 7 and which serves two purposes; first and mainly, it acts on the collar 13 pressing it outward and onto the tapered shoulder 18 of the spindle 9, causing the split members of 9to contract and hold the flying sandpaper 16 and 17 firmly in position; and secondly, it is used to remove the spindle 9 from the shaft 7;

after the set-screw or pin 31 has been removed.

Fig. 5 illustrates the manner in which the flying sandpaper 16, 17 is folded in the saw-cuts or split members of spindle 9. This construction permits flexibility of the rounded corners of the sandpaper or other abrasive sheet and enables it to follow the irregularities of the heel breast during the butting operation. The width of the sandpaper is such that it will not be greater than the width of the breast flap of the heel. However, it would be impracticable to attempt to match the exact width of the exposed area of any particular heel breast flap, because the width of this area varies in shoes of different types and sizes and also because in most types of shoes the grooves 3 and 3 are not parallel. For these reasons it is desirable to provide sandpaper which is narrower than the maximum width of the area to be treated on the average shoe. With sandpaper of such width the position of the shoe may be so determined, by gage means presently to be described, that the portion of the exposed area of the flap adjacent to the groove 3 may be finished without damaging the heel cover 60 where the latter is tucked into the groove 3; and since the width of the sandpaper is less than that of the space between the grooves, there will be no danger of the sandpaper damaging the heel cover a; where the latter is tucked into the groove 3. This operation may be repeated on the portion of the exposed area of the flap adj acent to the groove 3; and as the sandpaper may conveniently be more than half as wide as the area to be treated, the entire area can be finished in these two operations,

Suitably bolted to the top of the machine is a flat bar 19 provided with slots 20 and 21 through which extend the bolts 22 and 23 for tightening the bar to the top of the machine. The slot 21 is open at the left-hand end in order that when the bar is loosened it may be swung around to the left or right out of the way when it is desired to remove the spindle 9, At the right-hand end of the bar 19 and supported therefrom by means of bolts or studs 24 and 25 extending through the bar, is a guide block 26 provided with a spindle 27 upon which is mounted to move rotatably a guide wheel 28. The guide block 26 is provided with a suitable seat for a spring 29 and there is a complementary seat in the bar 19 for this spring. The bolts 24; and 25 are free to have vertical movement in the bar 19. Thus there is provided suitable flexibility for the guide wheel 28 enabling it to yield in a direction substantially transverse to the axis of the spindle when the guide wheel'runs in either oft-he recesses 3 or 3? of the heel breast. ,Fig. 6 shows how the guide wheel 28 is located with reference .to the recessesin the heel breast while the heel breast is undergoing the bufling opera tion. 30 represents a suitable pulley for driving the machine which may be connected half-way to the groove 3,

by belt or any suitable means to a source of power supply.

In operation, the shoe is held with the back of the heel facing the operator and with the guide wheel 28 engaging the recess or crease between the heel cover a and the flap b where both are tucked into the groove '3. The guide wheel 28 should first have ing the bolts 22 and Now, holding the shoe in the position above described, and with the guide wheel 28 properly adjusted, the operator can manipulate the shoe in such a way, with the guide wheel running along the entire length of the groove 3, that the flying sandpaper will operate upon an area of the heel breast flap which is as wide as the flying sandpaper and which extends the entire height of the heel breast. The flexibility of the flying sandpaper, by virtue of its peculiar arrangement, is such as to enable the sandpaper to accommodate itself to any variations in contour of the surface of the work, and thereby to impart a uniform finish to all portions of the heel breast surface which it engages. WVith the sandpaper narrower than the area to be finished, any danger of damaging the heel covering a beyond the opposite groove 3 will be avoided. Having thus finished an area extending from the groove 3, more than the operator then steps to the opposite side of the machine and repeats the above described operation,

this time presenting the crease overlying the groove 3 to the guide wheel. The remaining unfinished portion of the exposed surface of the breast flap 18 thus presented to the sandpaper, .and the finishing operation is completed. In order tov render unnecessary any change of position on the part of the operator, a second machine may be positioned to the left of the above-described machine, as the latter is shown in Fig. 3.

In that case, the spindle of the second machine would extend toward the left instead of the right. 7

i In Fig. 7 a modification of my invention is shown wherein instead of the flying sandpaper the spindle 9 isrsplit and two pieces of sandpaper d and e are shown which may be adjustedin the usual manner. Instead of flying, as in the constructionshown in Fig. 5, this sandpaper would be fastened rigidly to the spindle. Of course, it would be of such a width that it would not extend such relation with the olisher as not to beyond the recesses 3 and 3, as before deinjure the heelof the s 0e while the heel scribed, but this construction would not be breast of the latter is bein buffed.

as flexible as the one shown in Fig. 5.

Whereas the invention is more particularly designed to bufi a heel panel of the character above described, it is also possible by suitably arranging the guide or guard for the buffing paper to buff a panelof a heel of the type shown in the patent to Anthony Cocozella, No. 1,691,149, of Nov. 13, 1928.
