MACHINE FOR RUBBING AND POLISHING PAINTED CLOTH.

Specification forming part of Letters Patent No. 15,666, dated June 10, 1856.

To all whom it may concern.-

Be it known that I, DANIEL CUSHING, of the city of \Vheeling, in the county of Ohio and State of Virginia, have invented a new and useful Improvement in Machines for Bub hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing, making a part of this specification.

The nature of my improvement consists in applying mechanical means to the polishing of painted cloth, and by the use of rubbers worked by mechanism upon the stretched cloth I am enabled to execute the rubbing thereof with greater economy and rapidity than has heretofore been performed by hand labor.

The following description will enable others to construct the machine. In its details there may be slight variations and additions without affecting the general arrangement.

The frame-work consists of a pair of sills, A A, united by suitable cross-timbers.

B B are corresponding timbers, supported by uprights a a.

O O is a side frame connected with the main frame by an extension of the cross-timbers b 7) thereof. It supports the mechanism giving sustains the rollers, &c., and the painted cloth. As the movement of the rubbers and the cloth are not immediately dependent on each other,

itheir motion is received by independent puleys.

D is the moving pulley of the cloth portion, placed on a shaft, 6.

f is a screw, meshing in the spur-wheel E. The shaft of E carries the principal drum or roller F. By the friction on its surface the cloth is slowly drawn from the webroll G by the movement of the screw aforesaid.

H is a roller placed below the roller F, and I is a similar one placed above, for the purpose of making the cloth K embrace a greater portion of the surface of roller F.

L L L are cari'yingrollers, over whichthe cloth passes.

M is a roller placed below the axis of the web-roll G. Immediately over M is the water-trough N, for wetting the surface of the cloth as it is unrolled and passes under the roller M, said roller being covered with absorbent cloth, serving the purpose of a sponge, by which the painted cloth is moistened. By following the lines of the cloth as seen in Fig. 3, its movement over and under the several rollers and its reception 011 the receivingroller 0 will readily be understood.

The rubbing portion of the mechanism con sists of two hollow blocks, P I attached to bars h 71. To the under side of those blocks may be secured blocks of pumice-stone or other suitable substance of similar properties. The bars slide in suitable boxes or guides.

k k are rods extending from the eccentrics m m, from which they receive their reciprocating motion.

R is a pulley for receiving a band connected with the driving-power.

n is a pulley carrying a band, 1), from the large friction-drum F, which gives motion to the receiving-roller O by the band S passing over suitable pulleys.

It may be proper to explain that the method now employed is to rub by hand, and from the requisite repetition is very expensive, as each coat of composition must be rubbed down before another is applied. Therefore the accomplishing the same by mechanical means is a highly important improvement, by which the cost of production is materially reduced.

This improvement has been thoroughly tested on a large scale in the factory of the inventor.

The operation is as follows: The cloth received from a shell is slipped on the shaftroller G. It then passes under the spongingroller M, kept moist by water dropping from the trough N, by which its surface is moistened. It then passes over the rollers L L L and under the rubbers I I, and is received on the large drum F, by whose surface the cloth is drawn slowly over the machine. From the large drum or roller F it is wound onareceiv-' ing-roller, 0. As the cloth passes the rollers L L L it is subjected .to the action of the rub bers P I as described, by which the cloth is as perfectly rubbed or surfaced as now done by hand. Should it be found that the cloth unrolls too rapidlyfrom the roller G, aweighted clutch or strap may be applied to prevent it. Thus the tension of the cloth maybe kept up. In the proportions of movement of the several parts of the machine it necessarily falls to the discretion oi the builder; but as a general direction the cloth should move slowly along the length of the machine, while the rubbers should rapidly move across it.

Having described my machine, What I claim as my invention, and desire to secure by Letters Patent of the United States, is-

The mechanism, constructed and operating substantially in the manner described in the foregoing specification, for the purpose of rub bing painted or enameled cloth.

In testimony whereof I have hereunto signed my name before two subscribing Witnesses.

DANIEL CUSHING. Vitnesses:

JOHN F. CLARK, J O'I-IN S. HoLLINGsnEAD.
