IMPROVEMENT IN HAV-ELEVATORS.

Specification forming part of Letters Patent No. 148,267, dated March 3, 1874; application filed November 20, 1873.

To all whom t may concern: j

Be it known that I, DENNrs N. WEEsrEE, of Geneva, yin the county of Ashtabula and State of Ohio, have invented a certain new and useful Improvement in Elevators, of which the following is a full, clear, and exact description, reference being had to the annexed drawing, in which- Figure l is a side view of my invention as applied to the inclined track or ways of its supporting-frame, a portion of which is broken away. Figs. 2, 3, and 4 represent enlarged detached views of the several parts of mydevice.

Corresponding parts in the several figures are designated by corresponding letters.

This invention relates to a certain improvement in that class of elevators in which the car is automatically dispatched to its destination; and it consists of a bifurcated or forked lever, pivoted at the elevated end, or thereabout, of an inclined suspended track or ways, upon which travels a car, having lateral openings to receive the teeth of spring jaws or clamps attached to a yoke, with pendants or hooks to engage with, or take hold of, the bails of the rack having the weight or load to be elevated, Sto., substantially as hereinafter described.

To enable others to make and use my invention, I will proceed to describe it.

In the annexed drawing, A refers to a beam, supported upon transverse or curved pieces a a, resting upon, or secured to, four or more uprights, (not show11,) and from which beam depends an inclined track or ways, A', with'the rails a' a. B is a bifurcated lever, pivoted at the upper end of the inclined track, and having its tines or prongs pointed and tapering to permit them to easily fit or enter between the spring jaws or clamps and the car, which they do after the car has been returned to its elevated position, and thus disconnect the said jaws or clamps from the said car, when the emptied rack can be lowered or allowed to descend in readiness for a second load. Vhen the spring-jaws are to be united to the car, the lever B will yield upwardly to the ascending jaws, whose upper ends are thus brought in contact with the lower side of the tines of I said lever. O is a car, so adjusted to the inclined track A' as that its bottom is brought below the latter, and its trucks or wheels, which are journaled in its upper portion, thus caused to travel upon the rails a' a' of said track, by which adjustment the car is prevented from running off the track. The car O is provided with a second bottom, c, extending down below the first one, with a tapering or rounding surface, and supplied with lateral openings c1 c1, and an opening, c2, in its lower surface, arranged in a line with a fourth opening, c3, in the first bottom of the car. D D are the spring jaws or clamps, the

horizontal or uniting portion of which is fastened to the upper side of the yoke E, the jaws themselves being supplied, upon their inner or contiguous sides, with teeth or projections d d, with their lower ends or surfaces at right angles to the jaws, and their upper surfaces taperin g 0r beveled toward the outwardly-curved or divergent vends of the jaws, by which the said teeth are caused to adapt themselves to the bottom c of the car, and to glide into the lateral openings c1 c1 thereof as the springjaws D D are united to the same. The jaws or clamps D D having thus been united to the car, the rack, with its load, which has been attached to the yoke E through its hooks c e, will be in readiness for transportation, and the car to be dispatched to its destination. A rope, F, for manipulating or returning the car and rack to their elevated position after the latter has discharged its contents, is attached, at one end, to the yoke E, up through and from which it passes through the openings c2 and c3 in the car, thence along the lower side of the inclined track A', up under a pulley, f, -in the latter, and over two pulleys, j" f', in the beam A, from which it passes to, and is wound around, a nfin'dlass, or other suitable winding medium.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. The combination, with the carriage or car O c, supplied with the openings c2 c3, of the rope F, pulley j', and track A', substantially as and for the purpose set forth.

2. The track A', bifurcated lever B, car C c c2 c3, spring-toothed jaws or clamps D D, yoke E, rope E, and pulley f, all substantially as and for the purpose set forth.
