UNITED STATES PATENT FFICE';
l CHARLES CLARENI, OF NEW YORK, N. Y.
ATTACI-IING PU'LLEYS T0 SHAFTS.
Specification of Letters Patent No. 11,639, dated September 5, 1854.
To all whom t may concern.'
Be it known that I, CHARLES CLARENI, of the city, county, and State of New York, have invented a new and useful Improvement in Methods for Attaching Machine- Pulleys to Shafts.
The nature of my improvement consists in casting a recess in the pulley, one portion of such recess being deeper than the other, and in placing therein a small roller in such manner that when the pulley is placed upon the shaft it will bind and become a tight pulley when the shaft revolves in one direction, and loosen when the shaft is turned the reverse.
To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation, reference being had to the annexed drawings forming a part of this specification, in which,
Figure 1, is a side section of my improvement. Fig. 2, is a side view. Fig. 3 is a horizontal section.
Similar letters refer to like parts.
a, is the shaft; b, the pulley; 0, cavity in the pulley; d, roller.
The usual way of attaching pulleys to shafts, is to cut a key seat in the pulley, flatten one portion of the shaft, and attach the two together by driving in a key. This method is attended with expense, and requires considerable labor.
Under my improvement, all that is necessary to secure the pulley, b, to the shaft, a, is, in casting, to leave a small cavity, c, in the central portion of the pulley. This cavity requires to be a little deeper at one part than another, so that when the roller, d, is introduced, and the pulley placed upon the shaft, and the latter turned in the direction of arrow, 1, the pulley and shaft become bound tightly together.
In consequence of the cavity being shallow at one part, and gradually deepening at the other, that portion of the pulley acts in the manner of a cam upon the roller, d, so that when the pulley turns in the direction of arrow l, the pulley and shaft are bound together by the roller in the manner shown in Fig. 1. The pulley may be loosened and remo-ved by turning the shaft in an opposite direction (indicated by arrow, 2). It is 0bvious in this case that the roller, d, will roll back into the deeper portion of the cavity, so that it cannot touch or bind on the shaft, and the pulley may be then slipped off.
By making the cavity hollow in the center and shallow toward its ends, somewhat in the shape of a half moon, with a partition in the middle, two small rollers may be introduced, whereby the pulley and shaft will bind in whichever direction they are turned. Or, without having any such partition in the center of the cavity one roller will suf-y lice-though I prefer the other mode.
Some of the advantages which my improvement possesses over the ordinary mod e of fastening pulleys and shafts are :#convenience, cheapness, and expeditiousness. As the cavity is cast with the pulley, and as a bit of round wire will answer as a roller, it is manifestly much cheaper than the key seat mode, much more convenient both in application and removal, and much more eX- peditious, no hammering, filing, or cutting being required.
Having thus described my invention I claim- The method of fastening pulleys to shafts by having a cam cavity, or, recess in the pulley, and introducing therein a roller, substantially, as herein set forth.
CHARLES CLAREN-I.
