SHOE-POLISHING- MACHINE.

Specification of Letters Patent.

Patented Nov. 18, 1919.

Application filed March 31,1919. Serial No. 286,456.

My invention relates to shoe polishing machines and consists of the novel features herein shown, described and claimed.

Fig. 7 is an enlarged fragmentary sectional detail on the same plane as Fig. 5.

Fig. 8 is a fragmentary plan of the frame with the rollers omitted, parts being shown in section.

Fig. 9 is a vertical cross section of the frame with the rollers omitted, and taken on thevline 99 of Fig. 8 and looking in the direction indicated by the arrows. I

Fig. 10 is a fragmentary sectional detail on the line 10-10 of Fig. 9.

Fig. 11 is an end elevation upon a reduced scale looking in the direction indicated by the arrow 11 in Fig. 5, and looking at the exposed end in Fig. 4, and showing the rollers contracted.

Fig. 12 is a view analogous to Flg. 11

and showing the rollers extended.

Fig. 13 is a longitudinal central section of one of the rollers and taken on the line I 13-43 of Fig. 14.

Fig. 14 is an end elevation of the roller as seen looking in the direction indicated by the arrow 14 in Fig. 13.

Fig. 15 is an elevation of one of the roller shafts.

Fig. 16 is an end elevation of the shaft shown in Fig. 15.

The main frame 1 comprises a bottom 2,

end pieces

3 and 4 extending upwardly from the bottom, and a foot support 5 extending upwardly from the bottom and connecting the

end pieces

3 and 4.

The bottom 2 is mainly flat and has cups 6 pressed downwardly at its corners and longitudinally extending stiffening ribs 7 pressed downwardly at its sides. The cups 6 form supports to hold the base from scratching or marring the furniture or object upon which the machine is mounted and holes are formed at the centers of the cups through which screws may be inserted to fasten the machine to the support.

The

end pieces

3 and 4 have

inner plates

8 and 9 and

outer plates

10 and 11. The

inner plates

8 and 9 are formed integral with the ends of-the bottom 2 and are bent upwardly from the ends of the bottom at right angles and have upturned

spacing flanges

12 and 13 around their free edges. Bearing slots 14 and 15 are formed through the plate 9 parallel with the bottom 2 and in a line. Similar bearing

slots

16 and 17 are, formed through the plate 8011 a level with the bearing slots 14 and 15. The

rollers

18 and 19 are mounted between the

plates

8 and 9 upon the roller shafts 20 and 21, and the ends of the roller shafts extend through the slots 14, 15, 1.6 and 17. The

rollers

18 and 19 are substantially alike and are constructed as shown in detail in Figs. 13 and 14. Each roller comprises a body 22 having rounding tapers 2S and 24 extending both ways from the center,

flanges

25 and 26 at the outer ends of the tapers, and hubs 27 and 28 outside of the flanges, there being a central shaft bore 29 extending from end to end. The roller shafts 20 and 21 are substantially alike and are shown in detail in Figs. 15 and 16, and each shaft comprises a round straight body 30 adapted to fit in the bore 29, and

ends

31 and 32 having

flat sides

33 and 34. The

ends

31 and 32 extend beyond the end faces of the hubs 27 and 28.

An operating shaft 35 is mounted through the centers of the

plates

8 and 9, said operating shaft having a straight round body 36,

flattened ends

37 and 38, and a screw threaded portion 39 extending beyond the end 38. Levers 40 and 41 have fiat sided openings to fit non-rotatably upon the

ends

37 and 38, said levers normally extending both ways equal distances from the shaft.

Links

42 and 43 connect the ends of the lever 41 to the corresponding ends of the shafts 20 and 21. The

links

42 and 43 are connected to the ends of the lever 41 by

eyelets

44 and 45 pressed from the ends of the lever 41 and extending through openings in the ends of the

links

42 and 43, and the outer ends of the

links

42 and 43 have flat sided openings fitting nonrotatably upon the

ends

31 and 32 of the shafts 20 and 21, so as to hold the shafts from rotating, and so that the

rollers

18 and 19 will rotate freely on the shafts. In a like manner a lever 46 is fixed upon the end 37, and links 47 and 48 connect the ends of the lever 46 to the ends 31 of the shafts 20 and 21.

Tang openings

49, 50 and 51 are formed through the plate 9 just above the bottom 2, and similar tang openings are formed through the plate 8 just above the bottom 2. In a like manner tang openings 52 and 53 are formed through the upper edge of the plate 9 just inside of the flange 13, and similar tang openings are formed through the plate 8. The

openings

49, 50, 51, 52 and 53 serve to mount the

plates

10 and 11. Tangs 54 and 55 extend from the

plates

10 and 11 through the

openings

49, 50, 51, 52 and 53, and the inner ends of the tangs are bent to hold the plates in place, so that the

plates

10 and 11 cover the levers 40 and 41, the

links

42 and 43, and 47 and 48, and the other parts outside of the

plates

8 and 9.

An indicator arm 56 has a fiat sided open ing fitting non-rotatably upon the screw 39,

and a handle 57 extending outwardly from the outer end of the arm. The indicator arm 56 is parallel with the levers 40 and 41. Spacing washers 58 and 59 are placed upon the

ends

37 and 38 between the

plates

8 and 9 and the levers 40 and 41. A lock nut 60 is screwed upon the end 39 against the indicator arm 56, so that when the lock nut 60 is loosened the handle 57 may be manipulated to move the

rollers

18 and 19 to or from each other, and then when the rollers have been moved to the desired locations the lock nut 60 may be tightened to hold the roller shafts 20 and 21 rigidly in their adjusted positions, and at the same time allow the rollers to run freely upon the shafts. v

The foot support 5 is formed of sheet metaland comprises a central top plate 61,

side plates

62 and 63 extending downwardly and inwardly from the side edges of the top plate 61 and resting upon the bottom 2, there being

tangs

64 and 65 extending from the ends of the

side plates

62 and 63 through the

plates

8 and 9 and riveted, and tangs 66 and 67 extending downwardly from the

side plates

62 and 63 through the bottom 2 and bent laterally. A heel depression 68 is formed in the top plate 61.

In the practical operation the polishing cloth 69 cut to the desired length and width and having handles 70 at its ends is passed under the

rollers

18 and 19 and over the foot support 5. The shoe to be polished is placed upon the foot support 5 under the central portion 71 of the cloth, the handles 70 are grasped and the cloth drawn back and forth first with one hand and then with the other. The taper of the rollers provides a traveling motion for the cloth, so that as the cloth is reciprocated endwise it will move back and forth laterally of the cloth and endwise of the rollers. The

flanges

25 and 26 serve to hold the cloth from running beyond the ends of the rollers.

In Fig. 1 I have shown the operation of polishing the toe of a shoe 72. In Fig. 2 I have shown the operation of polishing the lower part of the instep by placing the shoe centrally upon the support 5 and tipping the foot first one way and then the other. In Fig. 3 I have shown the operation of polishing the upper part of the instep and the sides of the ankle by placing the heel 73 in the heel depression 68 and tipping the foot first one way and then the other.

Various changes may be made without departing from the spirit of my invention as claimed.

I claim:

1. In a shoe polishing machine a frame having a bottom, end pieces extending upwardly from the bottom, a foot support connecting the end pieces above the bottom, and rollers mounted in the end pieces above the bottom one on each side of the foot support, said rollers being tapered both ways from the center.
