SPECIFICATION forming part of Letters Patent No. 291,779, dated January 8, 1884,
Application filed August 25, 1883. (N0 model.)
To aZZ whom it may concern.-
Be it known that I, WILLIAM E. ROCKWOOD, of the city of Indianapolis, county of Marion, and State of Indiana, have invented certain new and useful Improvements in Pulleys, of which the following is a specification.
The object of my said invention is to improve the construction of that class of pulleys the rims of which are composed of rings of paper, so that the rims shall be rendered less liable to split off, without the expense and labor attending the use of metal rings or wasl1- ers and bolts or rivets. This object is accomplished by inserting in the rim a series of pins which support the rim and tie it together, as willbehereinaftermoreparticularlydescribed.
Referring to the accompanying drawings, which are made a part hereof, and on which similar letters of reference indicate similar parts, Figure 1 is a perspective view of a pulley embodying my invention, and Fig. 2 a central vertical section of the same.
In said drawings the portions marked A represent the shaft on which the pulley is mounted, B the hub thereof, and O the paper web and rim. The shaft A and hub B are not involved in my present invention, and need no special description.
The paper web and rim 0 is composed of sheets of paper secured together by pasting and pressingin amanner which is well known.
Instead of securing the stability of the rim by iron rings and bolts or rivets, as has heretofore been done, I insert wooden pins 0 tightly into holes extending through from side to side, preferably securing them in place with glue or some other adhesive substance. This is not only much cheaper than the old way, but is better, being lighter and free from all liability of rusting, as well as the danger of becoming loose and working off or chafing, which is present when the metal parts are employed.
Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is
1. In apulley the web and rim of which are composed of layers of paper, pins 0, extending through said rim from side to side, substantially as described,'and for the purposesspecified.
2. The combination of the hub B, the web and rim 0, composed of layers of paper secured together by pasting and pressing, and wooden pins 0, extending through the rim, substantially as set forth.
In witness whereof I have hereunto set my hand and sea], at Indianapolis, Indiana, this 21st day of August, A. D. 1883.
