GEORGE H. REYNOLDS, OF NEW YORK, N. Y. ASSIGNOR OF ON E-HALF TO THE CRANE BROTHERS MANUFACTURING COMPANY, OF CHICAGO, ILL.
WORM-GEARING.
SPECIFICATION forming part of Letters Patent No. 353,429, dated November 30, 1886.
Application filed February 13, 1886. Serial No. 191,797. (No model.)
To all whom it may concern: portion, B, and a lower semicircular portion, Be it known that I, GEORGE H. REYNoLDs, B, formed integral with the worm or screw of the city and county of New York, in the case B The casting composing the lower State of New York, have invented a new and portion, B, of the worm-wheel case and the 55 5 useful Improvement in WVorm Gearing, of worm or screw case B is provided on opposite which the following is a specification. sides with laterally projecting flanges b,
In constructing worm-gearing for elevators whereby the whole casing is supported on timand other purposes the worm-wheel and worm bers or a suitable metallic frame, D, forming or screw are often inclosed entirely within a. no part of my invention. 1o casing, the lower portion of which is oil-tight, The worm-shaft C may be connected diso that the worm and the portions of the wheel rectly with or be a part of the engine-shaft, which successively engage therewith may be whereby the worm is rotated, or may be proimmersed constantlyin an oil-bath, which will vided with pulleys or gears, whereby it is reduce friction and consequent wear. 7 driven. 5 My invention consists in a novel construc- The worm O is locked to turn with its shaft tion and combination of the worm or screw 0, but is free to slide thereon, and its connecand its shaft, whereby the endwise movement tion with the shaft is effected, as here shown, of the worm, which results necessarily from by two feathers or ribs, 0, on the shaft engagthe wear on its stationary thrust-bearings at ing grooves c in the worm, as shown in Fig. 2. 70 the ends of the worm, is prevented from being The endwise shifting of the worm, which will communicatedtothe shaft, and hence prevents take place by reason of wear on the thrust.- an engine, which may be coupled with the bearings, will then have no effect on the shaft shaft, from being thrown out of line. and will not shift it endwise. This is advan- The invention also consists in a novel contageous, as when an engine is coupled directly 75 struction of the worm-case and shaft-bearings with the shaft such movement of the shaft and thrust-bearings, whereby copious lubricawould throw the engine out of line.

As before stated, the parts BB" of the casing ing as formed integral with standards B*, which project upward and support bearings 11* for an upper drum-shaft, E; or such standards may be made separate from and secured upon'the part B of the casing.
\Vhat I claim as my invention, and desire to secure by Letters Patent, is
1. The combination, with a shaft and a worm which is constantly locked to turn with the shaft, but is freeto slide on the shaft, of a casing containing the worm and shaft and comprising bearings wherein the shaft may turn, and stationary thrust-bearings for the opposite ends of the worm, substantially as herein described.
2. The combination, with a worm and shaft, thrust-bearings for the worm, and bearings for the shaft, which are provided with transverse oil-holes leading to their inner surfaces, of an oil chamber or reservoir wherein the worm turns and in which are the thrust-bearings, and which is in communication with the transverse oil-holes in the shaft-bearings, whereby lubrication of the worm or shaft bearings and the thrust-bearings is insured, substantially as herein described.
3. The combination, with the worm and shaft 0 C, of the oil-case B containing the worm and comprising bearings for the shaft, and supplemental oil-reservoirs f, surrounding the shaft-bearings and communicating by holes 8 with the inner surfaces of the shaftbearing, and also communicating with the main oil-reservoir B substantially as herein described.
4. The combination, with a worm and its shaft, of a worm-case having at one enda hearing for the shaft and a thrust-bearing for the worm, abushing movable in the case and forming a bearing for the other end of the shaft 7 and a thrust-bearing for the worm, and a setscrew bearing on the bushing, and serving by its adjustment to take up wear in both thrust bearings, substantially as herein described.
, 5. The combination, with a worm and its shaft, of the case B", closed at the ends by heads B B, and containing at the ends removable bushings d cl, forming bearings for the shaft and thrust-bearings for the worm, and a single set-screw, d", inserted in the head B and bearing on the bushing d, and serving to take up wear in both thrust-bearings, substantially as herein described.
6. The combination, with a worm-wheel,A, and a worm and shaft, 0 O, of a case for the worm-wheel, composed of the upper portion, B, and the lower portion, B, having formed integral with it the case B for the worm, substantially as herein described.
7. The combination, with a worm-wheel,A, and a worm and shaft, 0 C, of a case for the worm-wheel, composed of the upper portion. B, and the lower portion, B, having formed integral with it the case B for the worm, and standards projecting upward from the upper case portion, B, and supporting bearings for an upper drum shaft, substantially as herein described.
