Description

UNITED STATES Application filed March 2, 1880.

To all whom it may concern:

Be it known that I, WILLIAM W. SToLL, of Brooklyn, New York, have invented a new and useful Improvement in Elevators, for which, with my knowledge and consent, a patent has been obtained in Great Britain, N o. 414, bearing date January 31, 1878, and issued to William Henry Power, of London, and of which the following is a specification.

This invention relates to that class of grainconveyers employing an elevator-trunk capable of being adjusted vertically and outwardly; and the invention consists in a novel combination and arrangement of parts, which will be fully hereinafter described, and pointed outin the claim.

The accompanying drawing represents a side view, partly in section, of my improved elevator as placed on a vessel or float.

A is the elevator-trunk; a, the elevator-shaft; B B, the two side pieces of the swinging arm or yoke; G, a vertically-adjustable sliding frame, to which the inner end of the swinging arm is attached or pivoted, and which slides between the vertical guides K K. D is the spout of the elevator discharging the grain.

The elevator A is of the usual construction. The swinging arm consists of two side pieces, B B. Near the forward end are the bearings for the elevator-shaft a, with the pulley o. The inner'end of the swinging arm is hinged to a shaft, c, having its bearings attached to the outer end or face of the sliding frame 0. On

this shaft e are fixed the pulleys f and g, which latter communicates motion to the elevator- PATENT OFF CE.

shaft to by means of a belt, cl. The shaft 0 is revolved by means of an endless belt or rope, u, from the driving-pulley m, passing over the pulley f, which is fixed on the shaft. This belt also passes over the guide-pulleys k and lon the inner face of the sliding frame and over the guide-pulley n, which, like the driving pulley, has its bearings on the fixed framework. This arrangement of pulleys admits of vertical motion of the sliding frame O.

The hoisting apparatus H has two drums, oneof which serves to raise or lower the sliding frame 0 by means of a rope passing over the block 1", while the other one serves to adjust the position of the outer end of the swinging arm by a rope passing over the blocks 0 and 1).

What I claim is- In an elevator, the combination of a framework constructed with vertical grooved guideways K, the sliding frame 0, arranged in such guide-grooves, the outwardly-extending arms B, hinged to said sliding frame and provided with pulleys for driving the elevator-buckets in the trunk A, which latter is pivoted to the outer ends of the arms B, and the hoisting mechanism having three winding-drums and independent ropes or bands passing up over pulleys, and connected, respectively, with the elevator-trunk, the swinging arms, and the sliding frame, all as and for the purpose described.

WVILLIAM W. STOLL.
