SPECIFICATION forming part of Letters Patent No. 508,102, dated November 7, 1893.

' Application filed I'ebrnary13 189 3- Serial no. 462,015. (No model.)

To alt whom git may concern:

Be it known that I, GEORGE H. FOWLER,

of Weedsporhin the county of Oayuga,i11

the State of New York, have invented new and useful Improvements in Hay-Carriers, of whlch the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

My invention relates to hay carriers of the class adapted to automatically grip the hoistng rope as soon as, from any cause, the pulling or hoisting strain thereon is reduced be low a point sufficient to hoist the load, and thereafter hold such load suspended until the hoisting strain is re-exerted or until the trip mechanism is operated to permit the lowering of the load. 7

My object is to produce a hay carrier in which a carriage is mounted upon a trackway. A frame hangs rigidly from the carriage, and carries the hoisting pulley, which is provided on one or both of its lateral faces with a series of projectingpins disposed at equal distances apart; in which auxiliary pulleys are mounted upon the right andleft of an auxiliary frame mounted and vertically movable in or upon the main frame, with one of which pulleys the hoisting rope engages to raise the auxiliary frame or yoke when under hoisting strain, and in which the hoisting rope is connected directly to the auxiliary frame or yoke, and passes downward and around an idler pulley which carries the hoisting hook, and thence passes upward and over the hoisting pulley; and in which, by shifting the rope to engage withthe other auxiliary pulley, the carrier can be operated in the opposite direction upon the trackway without reversing the carriage; and in which the auxiliary pulleys simultaneously grip thehoisting rope ,on opposite quarters of the hoisting pulley; and in which the trip mechanism operates to raise said pulleys simultaneously to release the rope from their grip so that the load can be lowered so long as the grip is thus broken.

My invention consists in the several novel features of construction and operation hereinafter described and which are specifically set forth in the claims hereunto annexed.

It is constructed as follows, reference being had to the accompanying drawings, in which- Figure 1, is a front elevation of the carrier complete. Fig. 2, is a vertical sectional and partly broken away front elevation of the carrier, showing the auxiliary frame or yoke as raised by the hoisting rope when under strain. Fig. 3, is a like view, omitting the hoisting hook and idler carrying it, showing the rope in dotted lines, and gripped between the auxiliary pulleys and the hoisting pulley, when the hoisting strain is removed from the rope.

A, is an ordinary trackway erected in any suitable manner.

B, is the main carriage frame upon which the wheels aare journaled, and -b is the grooved hoisting pulley journaled upon the lower end of said frame, between the parallel vertical bars c thereof which also straddle the trackway, part of one of said frame bars being also detachably connected to the other by means of the bolts d and the spacing studs e between said frame bars.

D, is a rectangular frame consisting of two sections, the upper rails h of which fit loosely between the frame bars, while its lower rail -hhangs below the main frame, and -klc are auxiliary grooved pulleys journaled between the upper corners of these frame sections, and these upper rails are also provided on one or both inner faces with a stud mwhich, when the auxiliary or gripping and locking frame is lowered, will enter one of the spaces between the pins m on one or both lateral faces of the hoisting pulley and lock it against rotation.

E, is the hoisting rope passed under the auxiliary pulley 7 (or over the hoisting pulley and down around the idler nand thence up to and detachably connected to the auxiliary frame, said idler being in the bight of the rope, and n' being the hoisting hook carried by said idler. At 1" is shown the trip carrying frame, in which the trip lever -r' is mounted, one end engaging with the auxiliary frame to lift and raise it and unlock the hoisting pulley when strain is applied to the trip-rope s; also by such lifting to raise the auxiliary pulleys and release the rope from their grip so that then the load can be loweredby slacking back the hoisting rope, so long as the strain continues upon said trip-rope, and when that ceases, from any cause, the load will draw the auxiliary frame down and re-lock the hoisting pulley and re-grip the rope between it and the auxiliary pulleys, leaving the load suspended. Also when the hoisting rope breaks, or the strain upon it is reduced below the point necessary to hoist the load, the Weight of the load will automatically draw the auxiliary frame down, lock the hoisting pulley and doubly grip the hoisting rope as before. The trip-rope can also be used to draw the carrier back to the loading point. Also when the hoisting-rope is shifted to pass out under the pulley 7a, the carrier can be used in the opposite direction.

WhatI claim as my invention, and desire to secure by Letters Patent, is-

1'. The combination, with the traveling carriage the frame suspended therefrom, and

therope of a hay-carrier, of the hoisting pulley journaled in said frame, the auxiliary frame mounted between the carriage frame bars and vertically movable therein, and to which said rope is connected, the gripping pulleys mounted upon said frame and adapted to grip the hoisting rope on opposite sides of the hoisting pulley, and a trip lever engaging with said auxiliary frame to raise said pulleys out of said gripping engagement.

2. The combination, with the traveling carriage, the rope of a hay-carrier and the hoisting pulley, provided with projecting pins upon its lateral face or faces, of a gripping and locking frame vertically movable in the carriage frame and connected to the rope, the locking stud or studs upon said locking frame adapted to engage with said pins, the pulleys upon the gripframe adapted to simultaneously grip the rope when the hoisting pulley is locked, and means to lift said grip frame to unlock said pulley and rope.

3. In a hay-carrier, the combination with the carriage, the hoisting pulley having projecting pins, and the rope, of a vertically reciprocating frame, a locking stud thereon adapted to engage with said pins, and having pulleys adapted to grip the rope on opposite sides of the hoisting-pulley.

In Witness whereof I have hereunto set my hand this 3d (lay of January, 1893.-

GEO. H. FOW LER.
