` Specification of Letters Patent.

Original applicationiled July 11, 1913, Serial No.7778,477. Divided and thisapplication led October 4,

f 1913. Serial 110.793,357.

To all 'whom'it may concern Be it known that. I, IIARRYLEVINE, a subject of the Czar of Russia', and a resident of4 the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Polishing-Machines, of which the followingis a specification. Y

My invention relates to improvements in polishing machines especiallyadapted for use in finishing the edges of leather'for.;

i an improved machine of this character which is of simple construction and efficient in use.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawing forming a part of this specication, and in which,

Figure 1 is a side view of a polishing machine embodying my invention, shown with parts broken away for the sake of clearness, Fig. 2, a vertical section of the same, Fig. 3, a perspective view of a polishing drum employed in the construction, and Fig. 4, a section taken through one end of said drum.

The preferred form of construction as illustrated in the accompanying drawing comprises a threaded spindle 1 having a iinishing drumv arranged thereon. Said drum is made in two semi-cylindrical parts 2 which are centrally grooved to fit over spindle 1 and are hinged together at one side. The other sides of drum parts 2 are provided with pins 3 and sockets 4, the pins on one part being arranged to fit within the sockets on the other part as indicated. The peripheries of drum parts 2 are covered by a heavy piece of leather 5 or similar material, said leather covering being provided with peripheral grooves 6 as shown. One portion of drinn parts 2 is covered by a sheet of sand paper 7 or other suitable abrasive, the ends of said sheet being drawn inwardly over the free ends of the drum parts and impaled over the corresponding ends of pins 3. A sheet of polishing material 8 suoli as corduroy or other suitable fabric is similarly `fastened over the remaining portions of drum parts 2. This arrangement constitutes a simple 'aiideficient means for securing the sheet-s 7 and i 8 to the drum parts. i

Each of the drum parts 2 is provided at each end with aprojecting pin 9 and plates 10.are providedy at each end of said drum partsandy are perforated to t over pins 9 whensaid drum parts are inclosed position.

overk spindle 1. Anabutment 11 is arranged on spindle 1 and a nut and washer 12..are provided on said spindle `adjacent the oppo- Patentea July 21,1911.

site end ofsaidy drum parts, as indicated.

By this arrangement it will be observed that by tightening nut 12 theplates 10 may be securely clamped against the ends of drum parts 2 and the drum parts thus securely locked on spindle 1. By loosening i nuts 12 the parts may be readily removed for the insertion of new abrasive and polish* ing sheets. The drum is protected by means of a housing 13 which is hinged to standards or supports 14 and is provided at its other end with a notch-15 engaging a thumb screw 16 by. means of which said' housing is removably secured in position over said drum. The housing 13 is provided at its top with a plurality of slots 17 which are arranged in registration with peripheral grooves 6 in the drum and serve to give access for thin stripsof material such as leather to said drum. The leather covering 5 furnishes a proper foundation and support yfor the abrasive and polishing sheets and grooves 6 permit sufficient depression of the abrasive and polishing sheets to impart a nicely rounded edge to articles dressed thereon.

While I have illustrated and described the preferred form of `construction for carrying my invention into effect, this is capable of variation and modification without departing from thespirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth, butl desire to avail myself of such variations and modifications as come within the scope of the appended claims.

Having described my invention what I claim as new and desire to secure by Letters Patent is:

1. A machine of the class described comprising a rotatably mounted drum having spaced peripheral grooves therein; a covering carried by said drum covering said grooves; and a member spaced from sald drum and having slots therein adapted to guide Work against the portions of said cov-V ering over said grooves, substantially as described. Y

2. A machine of the class described comprising a spindle a drum mounted on said spindle and having cured on said drum over saidgrooves; and a member spaced from said drum and having Work guiding slots therein, each of said slots being in registration With one of the grooves of said drum, substantially as de'- scribed.

3. A machine of the class described comprising a Vthreaded, spindle having an abutspaced peripheral grooves therein; a yieldable covering se? f', substantially as described.

In testimony whereof I have signed myV naine to thisr specification inthe presence 3 of two subscribing Witnesses;
