l yA. 0i WINN. WHEEL FOR SGOURING 0R BUFPING.

Patented Mar. 3, 1896.

ATENT OFFICE.

ALBY C. VINN, OF HAVERHILL, MASSACHUSETTS.

WHE-EL FOR SCOURING OR BUFFING.

SPECIFICATION forming part of Letters Patent No. 555,719, dated March 3, 1896.

Application filed J une 8, 1895. Serial No. 552,065. (No model.)

To all whom it may concern:

Be it known that l, ALBY C. VINN, a citizen of the United States, and a resident of Haverhill, in the county of Essex and State of Massachu setts,have invented certain new and useful Improvements in lVheels for Scouring or Bufng, of which the following, taken in connection with the accompanying drawings, is a specification.

My invention relates to certain improvements in wheels for scouring or bufiing shoe heels and bottoms.

In wheels as usually made the body has a cut-out portion hinged to the main body of the wheel, which cut-out portion forms a straining-piece to draw the sandpaper or buffin g-leather tight upon the roller. Various devices have been employed to draw said cutout or straining piece into place, but in most of them a separate tool had to be employed to secure said straining-piece in place.

The object of my invention is to produce a wheel the hinged or straining portion of which can be drawn in place without the use of any tool.

To this end the invention consists in the novel constructions and combinations of parts recited in the appended claims.

Referring to the accompanying drawings, Figure 1 represents a sectional view of a wheel embodying my invention, showing the hinged or straining portion in the closed position. Fig. 2 is a similar view showing the hinged portion released and raised ready to receive the sandpaper or bufng-leather. Fig. 3 is a vertical section taken on line x a; of Fig. 1, the hub being removed. Fig. 4 is a vertical longitudinal section of the hub. Fig. 5 is a cross-section taken on line y ly of Fig. 4E. Fig. 6 is a side view of the hub, and Fig. 7 is a View of the bushing detached.

A represents the body of the wheel, and A the hinged or straining portion thereof. In the center of the wheel is secured a ring or bushing B.

C is the hub which is secured to the driven shaft of the machine, said hub being free to turn for a short distance in the bushing B. The hub is formed with a V-shaped groove C' that extends for about two-thirds of its diameter. The upper edges of this groove are of a cam form, as shown at c,

The ring or bushing B is secured to the body of the wheel by means of screws b that pass through holes b, (see Fig. 7,) and it is also formed with a hole b2 that is screwthreaded to receive a screw E, the lower end of which passes into the V-shaped groove C in the hub and prevents lateral motion. This bushing is also formed with a circular aperture b3, through which the head of the screw D passes, said screw being carried by the hinged portion A'.

Supposing the wheel to be in the position shown in Fig. 2, and it is desired to attach a strip of sandpaper or bufng-leather, the paper or leather is placed in position and the hinged piece closed in the usual manner,the head of the screw D passing through the aperture b3 in the ring or bushing B and its head passing into the wide end of the V-groove C in the hub C. The shaft is then allowed to rotate in the direction of the arrow 1', (see Fig. 1,) which causes the head of the screw D to pass into the V-groove C', and the camshaped' upper surface draws the head down and with it the hinged piece A until the same is in the proper locked position, as shown in Fig. 1, the screw C preventing any lateral movement.

When it is desired to replace the worn-out sandpaper or bufting-leather with a new piece, all that has to be done is to stop the machine, then by hand force the Wheel back until the head of the screw D is released when the hinged portion A can be raised, and the old sandpaper or bufng-leather removed and a new piece supplied.

What I claim is- 1. The combination with a shaft having a boss with a re -entrant peripheral groove Whose overhanging portions are cam-shaped, of a scouring or bufing wheel surrounding said boss and having a movable section with a headed projection on its inner face to coact with the re-entrant peripheral groove and its cam-shaped overhanging portions substantially in the manner and for the purpose described.

2. A wheel for scouring or bufting shoe heels or bottoms consisting of a body having a hinged or strainer piece said body being secured to a ring or bushing, a boss having a V-groove cut therein the upper surface of IOO which gromre is of a @am form, a screw inname to this specification, in the presence of sorted in the hinged or straining piece, the two subscribing Witnesses, on't'his 18th day of 1o head of which screw is adapted to pass into January, A. D. 1895.

said groove in the boss as described and :L f v T T 5 screw inserted in the ring or bushing' and also Au C u IAN passing into said groove in the boss to pre- Titnessesz vent lateral motion as set forth. PORTER C. CRAY, In testimony whereof I have signed my HARRY J. COLE.
