SHAFT-COUPLING.
SPECIFICATION forming part of Letters Patent No. 701,017, dated May 27, 1902.
Application filed July 80, 1901- To (tZZ whom, it may concern:
Be it known that I, SAMUEL E. DIESCHER, a citizen of the United States, residing at Pittsburg, in the county of Alleghenyand State of Pennsylvania, have invented or discovered certain new and useful Improvements in Shaft-Couplings, of which improvements the following is a specification.
The invention described herein relates to certain improvements invshaft-conplings of the style or construction forming parts of Letters Patent Nos. 631,956 and 631,957, granted to me August 29, 1899; and the invention has for its object certain improvements in the construction of coil and the inclosing case whereby the former is caused to grip the shafts firmly by the closing together of the parts of the shell.
The invention is hereinafter more fully described and claimed.
In the accompanying drawings, forming a part of this specification, Figure 1 is a transverse section of the coupling and shaft, the plane of section being indicated by the line I I, Fig. 3. Fig. 2 is a view in elevation of the coupling and shafts, one-half of the inclosing shell being removed; and Fig. 3 is a sectional View on a plane indicated by the line III III, Fig. 2. I
In the practice of my invention I employ a sectional shell the parts 1 and 1 of which are adapted to be drawn together by means of bolts 2, the shell being recessed for the reception of the heads and ends of the bolts, so that the complete coupling presents a smooth exterior surface. Each of the sections is provided with recesses 4 and 4* for which form the gripping members of the coupling. These coils or gripping members are preferablyformed of bars square in crosscoiled bars will have a large bearing upon the surfaces of the shafts. The ends of the coils are provided or formed with shoulders 6 and 7, the shoulders 6 of the adjacent ends of the coils having bearings upon the shells adjacent to the recesses wherein the coils are arranged. The shoulders at the outer ends of the coils have bearings upon movable blocks 8, which are preferably wedge-shaped, so that by their movement on their seats by the screws 9 an adjustment of the tension of Serial No. 70,216. (No model.)
the coils on the shafts when the coupling is formed can be effected. It will be noticed by reference to Figs. 1 and 3 that the inner end of each" coil has a bearing upon one section of the case or shell, while the opposite end has a bearing upon the adjustable block which is mounted in the other section, so that by drawing the two sections of the shell toward each 'other the coils will be drawn tightly around the shafts. Each shell-section is a duplicate of the other, sothat they can be readily placed together by any ordinary mechanic.
In formingthe couplings the coils are made with an inner diameter slightly greater than the diameters of theshafts to be connected, so that but a small movement of the ends of the coils is required to effect a gripping action upon the shafts.
In applying'these couplings if it is found that the two sections can be drawn together by their bolts so that their edges meet without applying sufficient tension to the coils the bearing-blocks are adjusted inwardly so that their bearing-surfaces will be above the plane of the inner surface of the sections, so that when the sections are drawn together by the bolts 2 a greater tension will be applied to the coils, drawing the latter tightly against the shafts.
I claim herein as my invention 1. A shaft-coupling having in combination a sectional sleeve, coils arranged within the sleeve, the opposite ends of the coils bearing upon opposite sections and means for drawing the sections toward each other, and thereby reducing the diameter of the coils, substantially as set forth.
2. A shaft-coupling having in combination a sectional sleeve, coils arranged within the sleeve, one end ofeach coil having a bearing on one of the sleeve-sections, and adjustable bearings for the opposite ends of the coils arranged in the other section, and means for drawing the sections toward each other and thereby reducing the diameter of the coils, substantially as set forth.
In testimony whereof I have hereunto set my hand.
