PULLEY FOR HOISTING MACHINES.
No. 243,738 Patented July 5, 1881.,
5%?7255355 I wizgw UNITED STATES PATENT OFFICE.
SEBASTIAN STUTZ, OF PITTSBURG, PENNSYLVANIA.
PULLEY FOR HOlSTlNG-MACHINES.
SPECIFICATION forming part of Letters Patent No. 243,738, dated July 5, 1881.
Application filed May 23, 1881.
To all whom it may concern:
Be it known that I, SEBASTIAN STUTZ, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Pulleys for Elevators or Hoisting Machines, of which the following is a specification.
Myinvention relates to improvementsin pulleys for hoisting or elevating machinery; and the object of the invention or improvement is to prevent loss of time and pieces. I attain this object by the construction illustrated in the accompanying drawings, in which- Figures 1 and 2 represent a pair of hexago nal pulleys fixed upon their shaft, in connection with the elevator-chains. Figs. 3 and 4 represent details of the pulley, on a larger scale.
Similarletters refer to similar parts throughout the several views.
Polygonal pulleys employed for hoisting or elevating material upon different heights are constantly exposed to great wear, owing to the friction of the chains. The parts most exposed are the corners, tending continuously to cut in and acquire a circular form. As the windin g capacity of the pulley greatly depends upon its polygonal angle, it happens frequently that the chain, instead of being wound around, is slipping backward or remains stationary, because the corners are rounded and are unable to maintain the chain in its proper position.
(No model.)
The only remedy for such cases is the putting in of new pulleys. The change of pulleys constructed in one piece not only requires much time and labor, but causes great loss of metal, to be thrown away or sold for a trifle.
To prevent such loss of time and money I have constructed the pulley represented by Figs. 3 and 4 with its angle-pieces a a independent and fixed to their places either by bolts 12 or by rivets r, as the case may be. The system is shown on a hexagonal pulley, but it may as well be applied to any other polygonal form used for this purpose. Great advantages are gained by this system, as the change of angle-pieces can be effected in a very short time and without taking the pulleys from the shaft or their place. The angle pieces may also be made of steel or other hard metal.
What I claim, and desire to secure by Letters Patent, is t 1. A polygonal pulley for elevating or hoisting machines, having independentan gle-pieces fixed at its corners, substantially as described, and for the purpose set forth.
2. In a polygonal pulley, the an gle-pieces a, secured to their places either by bolts b or rivets r, in combination with the pulley P, for the purpose set forth.
SEBASTIAN ST UTZ.
