POLISHING ROLL FOR SHOES Filed June 10. 1929 h in Fig.1
6'+ 5 4 5 Jnvenfor Patented Sept. 29, 1931 UNITED STATES KARL WOLLNY, OF WEISSENFELS, GERMANY POLISHING ROLL FOR SHOES Application filed June 10, 1929, Serial No. 369,651, and in Germany February 26, 1929.
The present invention relates to a rotary finishing or polishing roll especially for shoe pounding machines. The pounded parts of the shoes are worked upon and fin- .6] ished by a polishing roll. To this end the polishing roll is arranged on the end of the shaft of the pounding drum. The roll is heated by friction. This mode of heating has the advantage against heating by gas or electricity, that the danger of fire is obviated and the ducts for electricity or gas are not needed. The machine therefore can be erected and moved anywhere and need not be confined to a certain place. The friction is I mostly produced by a piece of felt pressed against the working surface of the roll. To
prevent the burning of the felt it must be saturated with oil. But this is a great disadvantage because the upper leather becomes stained especially if it is light coloured.
According to the present invention these drawbacks are obviated and effective heat ing of the polishing roll is obtained in a very short time. To this end there are provided on both ends of the polishing roll prolongations with cylindrical friction surfaces cooperating with friction bands. The friction surfaces are concentric With the shaft of the roll and are placed symmetrically to the latter. By these means a uniform heating of the working surface is obtained and radial and axial stresses of the shaft by friction are obviated. The extent of the friction itself can be controlled by tightening or loosening 5 the bands. One end of the bands is fastened to the machine-frame while the other end is connected thereto by a regulating screw.
An embodiment of the invention is illustrated in the accompanying drawings.
Fig. 1 is a view of an entire pounding machine provided with the new polishing roll.
Fig. 2 is an elevation and partly a vertical section of the roll.
Fig. 3 is a cross-section of the roll.
The pounding drum is fastened on a shaft 1. On the left end of the shaft is keyed a polishing roll 2. The polishing roll has prolongations on both ends forming symmetrical cylindrical surfaces 9, 9 encircled by 0 friction bands 3, 3. These bands consist of iron sheet bands covered on their inside with fibre. The end 4 of every band is fastened on a bar 5 fixed to the machine frame. The end 6 of the bands is connected to the end 4 by a set-screw 7. By tightening the bands the heating of the polishing roll can be regulated.
It is evident that the polishing roll is heated from both ends in a uniform manner.
What I claim is:
A rotating shoe polishing roll, a working surface on the roll, friction surfaces on both sides of the working surfaces of said roll and concentric to the axis of rotation of the roll, friction bands embracing the friction sur- :55 faces, means for fastening one end of the frictin bands to a fixed part of the machine, and screws for connecting the other end of the bands with the said first mentioned band ends and adjustable for tightening the bands. 7
In testimony whereof I aiiiX my signature.
KARL VVOLLNY.
