SPECIFICATIGN forming part of Letters Patent No. 290,674, dated December 25, 1883 Application filed October 22. 188). (No model.)
8 T0 coZZ whom, it may concern:
Be it known that I, FRANK XV. FULLER, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented certain new and useful Improvements in Automatic Belt- Shifters for Elevators, of which the following is a specification.
My invention relates to an improved beltshifter or stop mechanism for the hoisting-gear of elevators 5 and it is equally applicable to such elevators as are operated by endless belts and to those which are operated by hydraulic power and are controlled by valves or stop cooks, the object of my invention being to provide a motion-controlling device which shall be automatic in its operation when the elevator-cage shall have reached the end of its travel, whether at the top or bottom of the well-hole, and yet at the same time be susceptible of operation by hand at any intermediate point. I j attain these objects by the mechanism illustrated in the accompanying drawings, in which-- Figure 1 is a perspective view, showing the general construction and arrangement of my improved automatic belt-shifter. Fig. 2 is a vertical sectional view of the beltshifting gearing. Fig. 3 is a face view of the toothed segment and its connecting-gearing. Fig. 4 is a sectional plan view of the rope-sheave, the belt-shifting rods and a portion of the gearing; and Fig. 5 is a face view of the same.
Similar letters of reference are used to indicate like parts throughout the several figures.
In the drawings I have shown my improved device applied to an elevator hoisting mechanism in which the cable-winding drum is operated by a worm-andpinion gear and endless belts. The worm-and-pinion gear are contained within the case A, Fig. 1, and are of the usual form.
B is the winding-shaft, upon which is keyed the winding-drum 0, around which is wound the bight or fall of the rope or cable attached to the elevator-cage and passing over sheaves at the top of the well-hole in the usual manner.
D is the drive-shaft, upon which is placed the usual number of fast and loose pulleys, E E, and F F are the endless belts, by which the whole mechanism is operated.
The winding-shaft B is carried through the case A, and is provided upon its outer end with a loosely-journaled toothed segment, G, and a fixed pinion, H. (See Fig. 2.) In practice the hub of the segment is first slipped over the end of the winding-shaft, and then the pintle or shaft of the pinion is forced into a hole drilled in the center of the end face of the shaft, and keyed in any suitable manner. A small washer should be placed between the end of the segment-hub and the side of the pinion to prevent friction.
Upon the lower portion of the case A, I form a socketed stud, I, into which is forced the end of a short shaft, J, which carries the looselyjournaled pinion K, meshing with the toothed segment G. The said pinion K is provided with an elongated hub or sleeve, L, which extends to the outer end of its supporting-shaft J, and upon the extreme end of this sleeve I key the rope-sheave M, around which is passed a small cord or rope leading up through the well-hole and within convenient reach of the operator.
Upon the sleeve L, between the pinion K and the rope-sheave M, I place the loosely-journaled cog-wheel N, which meshes with the pinion H upon the end of the winding-shaft; and it should here be remarked that the outer face of the segment G is to be provided with an adjustable lug, 0, while the opposed face or side of the cog-wheel N is to be provided with adjustable lugs P Q, arranged in a nearly diametrical line, all for a purpose to be hereinafter more fully described.
The web of the rope-sheave is made solid, or without arms, and is formed with two cam slots, R R, of equal size and equally distant from the hub. (See Fig. 5.) These cam-slots receive the wrist-pins S of the belt-shifting rods T T, which reciprocate in suitable slides, U U, attached to the case A, and are placed one upon each side of the ropesheave, as shown in Fig. 4. The outer ends of the shifting-rods are furnished with the usual upwardly-projecting prongs or forks, that pass on either side of the belts.
The operation of my improved automatic IOC) shifting-rods TT in a horizontal direction for a distance sufficient to throw the winding-belt upon the fast pulley, when the drum 0 and its shaft will be rotated and the cage will ascend. As the shaft B revolves its motion will be communicated through the pinion Hto the cog-wheel N, which, owing to its large size, will revolve at a comparatively slow speed. By the time that the cage has nearly reached the limit of its travel the said cog-wheel N will have revolved sufficiently far to bring the lug Q into contact with the lug O on the segment G and produce a semi-revolution of the same, which will be imparted to the pinion K, and through it to the rope-sheave M, and, through the medium of the cam-slots R and rods T, cause a quick shifting of the belts and a stoppage of the elevator. In descending, the movement of the parts will be reversed, but the re sult when the cage shall have reached the bottom. of the well hole will be the same as that last above described.
I do not propose to confine the application of this belt-shifting device to elevators alone, as it is equally applicable to all machines in whicha carriage or frame is reciprocated along a horizontal track.
Attached to the segment G there should be placeil a small cam operating a lever controlling the usual brake; but I have not deemed it necessary to illustrate this brake, as it forms having lugs engaging with a lug upon the seg ment G, and a fixed rope-sheave, M, having in its web cam-slots R It, for the reception of wrist-pins upon the reversing or belt-shifting rods '1 '1, substantially as shown, and for the purpose set forth.
I11 testimony that I claim the foregoing I have hereunto set my hand and seal.
FRANK XV. FULLER.
