WILLIAM W. CAMPBELL, OF INDIANAPOLIS, INDIANA, ASSIGNOR OF ONE- HALF TO WILLIAM H. THOMAS, OF SAME PLACE.
PULLEY-COVERING.
SPECIFICATION forming part of Letters Patent No. 276,559, dated May 1, 18813,
Application filed March 8. 1883. (No model.)
To all whom at may concern:
Be it known that I, WILLIAMW. CAMPBELL, a citizen of the United States, residing at Indianapolis, in the county of Marion and State 5 of Indiana, have invented a new and useful Improvement in Pulley-Coverin g, ofwhich the following is a specification, having reference to the accompanying drawing.
My invention relates to a covering for the IO periphery of a pulley for transmitting power by means of belts or frictional contact.
The objects ot'iny invention are, first, to provide a means for causin ga leather or canvas covering to adhere to the pulley more strongly 1 than has heretofore been possible without the use ofrivets; and, further, to provide a pulley-covering which shall have a good wearingsnrtace and at the same time be slightly elastic.
It has heretofore been found diflicult, if not .20 impossible, to fasten a leather or canvas covwhen applied to both surfaces of the paper, will unite firmly with thesurface of the pulley and with the leather,and a covering is produced that will not start or peel up from the pulley, but will remainfast until worn out. 5 I find also that when several layers of paper are used the first being cemented to the pnlley, audeacli succeedinglayer cemented to the others, and the leather or canvas then ccmented to the outer layer of paper, acovering 40 is produced which, when a belt is run thereon, yields slightly to the pressure, thus causing the belt to set very closely thereto, and preventing any' slipping of the belt.
The accompanying drawing illustrates my 5 invention.
The figure represents a sectional view ofan iron pulley covered as l have described.
a, is the riinof the pulley, b is the paper, and o the outside covering. 50
I claim as my invention,
The combination, with a pulley and a leather or canvas covering therefor, of one or more layers of paper interposed between and cemented to said pulley and said covering, sub- 55 stantially as and for the purpose set forth.
WILLIAM W. CAMPBELL. \Vitnesses:
