DANIEL DOCKSTADER, OF FONDA, NEW YORK.
HAY-ELVATOR.
SPECIFICATION forming part of Letters' Patent No. 248,149, dated October 11, 1881. Application fid J'u s, ss. (No model.)
' State of New York, have invented a new and Improved Hay-Elevator, of which the following is a specificaton.
The object of this invention is to furnish an improved elevator and carrier; and to this end the invention consists of an improved swinging dog and a catch Operating in combination with the sliding block of the elevator, all of which will be hereinafter set forth.
In the accompanying drawings, Figure l is a sectional side elevation of the elevator in po- .sition. Fig. 2 represents a plan of theinproved catch and (log. Fig. 3 is a vertical end section on line w az, Fig. 1. y
Similar letters ofirefervnce indicate corresponding parts.
In the drawings, A represent's the elevatorframe, suspended from a track, B, by means of straps and wleels C C', respectively, the straps G being secnred on opposite sides of the frame Aand Extended npward, and havingtheir ends turned over at right angles, and having pivoted in them the wleels C', that rest upon the track B'. Said track B is designed to be suspended from the rat'ters of a building by suitable rods, D.
In the under face of the track B is a 1ongi'-- tudinal socket, a, in which is pivoted a catch, E, lying lengthwise with said socket a, whose purpose will be hereinafter set forth.
Within the carrier-frame A is a sheave, G, that is set on a transversc shaft, G', and revolves in a vertical plane; and placed higher np in frame A, and a shor t distance to the left,
as shown in Fig. 1, is the dog H, pivoted on a transverse rod, H in such a position that the point of said dog H shall reach to the periphery of said sheave G, and serve to stop the elevating-chain K at the proper point, as will be hereinafter described. Said dog H is provided with a triangular socket', b, in one side of the end farthest from the sheave Gr, for the en ga gementtherein ofthe catch M, as will be described.
The catch M is curved, and has a pointed and hooked head, as shown, and is pivoted ou a transverse rod, M', in rar and a little below the dog H, with its concave edge and hook toward the said dog H, and with its head uppermost.
The elevating-chain K has one end made fast to astaple, c, fixed in therear end of the frame A, while its other end is attached by a swivel, g, to a rope, K' ,which is pas ed over the sheave Gr and out of an orifice, g', in the front end of the i'rame A. This chain K is used instead of a rope, because of its superior (lurability under contact with the block L and dog H.
A sliding block, I, provided lwitlra vertical slot, h, extending through it, is Suspended in frane A on a transverse rod,'l', that passes through the frame A from side to side thereof, so -tlat the enlarged head of saidblock I hangs below' said frame A.
'On the bight oftl e chain K is a pulley-block and hook, L, and on said chain K is rigidl y secured a ring, f, of leather,-metal, or other material, against which the point of the dog H is to engage. When the parts are in place, as shown in Fig. 1, the elevato' isin position for loading, the hooked end ot' the catch E being entered in the orifice Ic, made in the rear end ot' the frame A, and thereby holding said frame Afixed. When thehay-fork,(notshown,)which is designed to be connected With the block and hook L, is loaded, the chain K and 'ope K' are drawn in the direction of the arrow, Fi g. 1, and the block L thereby drawn upward in contact With the sliding block I, and forces said block I up against the convex edge of the catch M, thereby moving said catch M, so as to disengage it from the socket b of the (log H, and permit the latter to fall with its point upon the time the block I is also brought in contact with the catch E, thereby raising the latter, so that it can pass out of the orifice k. Thus'the ele- Vator A isfree to move, and the load Suspended from the block and hook L is held at suitable elevation, the chainK being prevented from being drawn back by the engagement of the point of the dog H upon said chain K just in rear of the stop or ringf, which latter by this time has arrived at the top of the sheave G. By means of the rope and chain K' K the elc- Vator A is then moved to the desired place for depositing the load. .When the load is removed, said elevator A may be moved back again for another load, and the hooked end of the catch E, entering the orifice 76, passes to one' side of the catch M and over the short end. of the dog H, and, pressing said short end down,
IOO
thereby disengages the point of' said dog H from the stop or ring f, and thus permits the block and hook L to deseend for another load. At the same momentthe block I, being released from the Upward pressure of the block L, falls by its own gravity hack to its primary posii l claim as new and desire to secure by Letters Patent 1. In a hayelevator, the combinetion, with zo the carrier-treme A and the pulley-hloek L, of the dog H, provided with Socket b, the catch M, and the sliding block I, suhstantiallyas and for the purpose set forth.
2. In zt hay-elevator, the combination, with 25 the track B, provided with the catch E, and the pulley-bloek L, of the carrier-fra me A, providedwith the dog H, the catch M, and the sliding block I, substantially :s and for the purpose set fo'th.
