Description
JOHN SIMPSON, OF DEGATUR, GEORGIA.
BAND-PULLEY.
To all whom, t may concern.'
Be it known that I, JOHN SIMPSON, of Decatur, in the county of Dekalb and State of Georgia, have invented a new and Improved Manner of Forming Faces of Drums, Pulleys, &c., in Which Bands are Used for Propelling Machinery or other Purposes; and I do hereby declare the following to be a full and exact description thereof, reference being had to the accompanying drawing, making a part of this specification.
The nature of my invention consists in greatly increasing the adhesiveness between a belt andthe drum or pulley which it passes over and receives motion from, or communicates motion to, without increasing` its tension. This I perfectly and permanently accomplish by covering the face of the driving and receiving drum or pulley with a -coating of india rubber secured in any convenient manner. y
The accompanying drawing is a perspective view of a pulley, detached from its shaft, having a coating of india rubber upon its face or periphery.
The giving an india rubber covering to a drum or pulley greatly increases the power of a belt, prevents all danger of its slipping, and very considerably reduces friction, in consequence of less tension of the band being required to produce a given effect when the drum or pulley is prepared in this manner.
l/Vhat I claim as my invention and desire to secure by Letters Patent, is-
The giving the face or periphery of drums, pulleys, &c., upon which bands are used, a coating of india rubber, or some other gum covering of a similar nature, for
the purpose herein set forth.
JOHN SIMPSON.
itnesses Z. C. ROBBINS, JOHN M. THAYER.
