GEORGE M. BIRLIN G, OF MASON CITY, ILLINOIS.
PU LLEY-COVERING MACHINE.
SPECIFICATION forming part of Letters Patent No. '714556, dated November 25, 1902.
Application filed March 24, 1902. Serial No. 99,755. (No model.)
To all whom it mayponocrn:
Be it known thatI GEQRGE liIBIRLING, a citizen of the United States, residing at Mason City, in the county of Mason and State of Illinois, have invented new and useful Improvements in Pulley-CoveringMachines, of Which the following is a specification.
This invention'relates to pulley-covering machines. Its object. is to provide a cheap, durable, and efficientdevice which mayeffectually retain and stretch the covering over the surface of the pulley while the same is being riveted thereto.
In accomplishing the desired result I employ a peculiar construction of machine, the novel features of which will be specifically described hereinafter and illustrated in the accompanying drawings, in which Figure 1 represents a perspective view of a machine constructed in accordance with my invention. Fig. 2 is an end view of the same. Fig. 3 is a detail perspective view of one of the clamping-jaws. Fig. 4: is a similar View of one of the remaining jaws. Fig. 5 is a vertical longitudinal'sectional view of the machine complete. Fig. 6 is a top plan view of the operatingh-andle and pulley. Fig. 7 is a detail perspective viewof the pulley-shaft.
The reference-numeral 1 designates a table or othersuitable support, on one end of which is rigidly secured the base 2 of the machine, whichcomprises an approximately rectangular block of wood, metal, or other desirable material.
On one end of the base is secured a rigid jaw 3 of the machine, which preferably consists of a channel-iron provided with an out wardly-projecting flange 4, on which one of the adjustable or movable jaws 5 and 5 rests. The channel-iron fits over the end of the base and is secured thereto by two adjusting- bolts 6 and 6, which extend through the block, longitudinally thereof, and are provided at their threaded extremities with adj usting- nuts 7 and 7. These bolts also pass through elongated slots 8 in the movable jaws and are provided with heads 9, whereby the jaws may clamp the material to be used in covering the pulleys. It will be noticed the inner faces of the several jaws are provided with irregular surfaces, whereby any tendency of the material to slip will be obviated. Attention is also directed to the fact that the movable jaws are adjusted laterally, so that they may be forcedapart to grip the longitudinal edges of the material more tightly than the center when tapered pulleys are to becovered.
The reference-nu meral 10 designates a shaft provided with angular ends 11 and 12 and having a longitudinally-extending groove 13, in which is adapted to be seateda key 14, which also engages a coinciding groove in the hub of the pulley 15.
A handle is provided to engage the shaft 10, and it consists of two lovers 16 and 17, connected at one of each of their ends by a pivot, whereby their remaining or free ends may swing laterally. The free ends are provided with angular openings 18, corresponding to the angular ends of the shaft 10, which they engage. The levers 16 and 17 may be attached to and detached from the shaft 10 by swinging their free ends laterally. The shaft 10 is made of sufficient length to accommodate it to any width of pulley.
0n the pivot of the levers is fastened a hook 19, from which a chain 20 depends and which in turn is designed to be connected to a similar hook 21 in the table or other suitable support 1. In lieu of this chain any other suitable flexible connection may be employed; but I prefer to utilize a chain, because any of the several links may be caused to engage either of the hooks, according to the diameter of the pulley to be covered.
In using the machine the material is first riveted at one end to the pulley, and the free end is then clamped between the jaws by the bolts 6 and 6, after which glue is applied to the pulley and covering, so as to make them adhere. The operator then bears upon the handle, and after the material is stretched over the pulley sufficiently the proper link in the chain 20 is caused to engage the hook 21. The operator may then place the rivets at proper places, completing the work upto the seam, when the clamp may be released and the covering trimmed.
It will be noticed that the lower surface of the pulley constitutes a fulcrum, from which leverage is exerted to stretch the belt tightly over the surface of the pulley. After the covering of leather or other material is firmly fastened the edges are trimmed, leaving the pulley free to be used.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. In a device of the character described, the combination with a support, a base thereon, clamping devices adapted to receive and retain a covering material, a handle for engaging a pulley on which the covering material is to be secured, said handle being designed to be operated to stretch the covering, and means for securing the handle in position when the material is stretched.
2. In a device of the character described, the combination with a support, a base thereon, clamping devices adapted to receive and retain a covering material, a removable handle comprising two pivoted levers adapted to engage the pulley, said handle being designed terial is to be secured, said handle being designed to be operated to stretch the covering, and means for securing the handle in position when the material is stretched.
In testimony whereof I affix my signature in presence of two witnesses.
