PATENT HAY ELEvAToR AND CARRIER.

SPECIFICATION forming part of Letters Patent No. 273,455, dated March 6, 1883.

Appncann filed May 4, 1882. (No model.)

' To all whom it may concern:

' Be it known that I, GEORGE W. BROWER,`

ot' Crawfordsville, in the county ot'lVlontgomery and State of Indiana, have invented a new and Improved Elevator and Carrier, of which the following is a full, clear, and exact description.

My invention relates to elevating and carrying apparatus such asis employed to unload hay by a fork let down from above upon a wagonload, raised therefrom, with its load carried overthemowanddischarged,andthen returned over and let down, as before, on the wagonload, the contrivances being automatic except the power for handling the hoisting-ropes.

|l`he nature of the invention consists in the several combinations and arrangements of parts, substantially as hereinafter more fully set forth and claimed.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a side elevation ofthe improved hoisting and carrying apparatus, with a part ot the frog in section. Fig. 2 is a transverse section ofthe carrier, taken on line .fr of Fig. l. Fig. 3 is a plan view of the frog inverted. Fig. 4 is an inverted plan view ot one of the knot-cribs of the weighted rope, and Fig. 5 is a perspective view thereof.

Arepresents the carrier, consisting of a horizontal plate or bar, a, of suitable length, suspended below the beam `B by hangers C, which are supported upon the 'axles D ot rollers E,

traveling on said beam. p

To each end ot' the carrier A there is attached a knot-crib, E', for the control ot' the knot F of the weighted rope G and the hoisting-rope J, and from under said carrier, near each end, it has hanger-brackets H, in which sheave-pulleys I are pivoted, for the hoisting` rope J, by which the fork K is raised and lowered and the carrier is drawn along the beam B to the place of discharging the fork. Said carrier also has side bars, L, extending from one to the other ot' the, brackets H, and also ears M, in which the grapple-hooksN are pivoted, that'engage and hold the fork K by the conical head O ot' the fork-sheave frame O for holding said fork while being carried receive and guide the head O between the points Q of the hooks to insure the connection, said guide being slotted at P for the hooks to work in and out of it.

Over the bell-guide is a latch-bar, R, with notches S; to lock the grapple-hooks together when holding head O by the engagement ot' the pins T of said hooks in said notches S, the said' latch-bar being titted to rise and fall, so as ,to drop on and rise oit' from said pins to lock and unlock the ,grapple-hooks. The bar R is arranged in the slot V ot' the bell-guide, and it is slotted-at W to straddle the grapplehooks, and from the center it has a stern, X, extending up through the top ot` the carrier and terminating in a T-head, Y. The grapplehooks have an arm, Z, extending up each side ot' the carrier A a little above it, and about as high as the top of T-head Y when latch Ris in its lowest position. The head Y is elou gated in the lengthwise direction of the carrier, and is to lift the latch off of pins T, to let the grapple-hooks open when the fork K is required to descend. It is so lifted by being forced up the incline a of the frog A when the carrier is pulled back to the frog after discharging its load for descending and for hoisting another load, the said carriers being pulled back by the c weighted return-cord G. As soon as the latch has been so lifted to release the grapple-hooks the arms Z of the said grapple-hooks pass along the incline b ot' the frog, and thereby the hooks N are opened, the head O of the fork let free, and the fork lettalltogetitsloadnhe hoistingrope J being thenk slack and running through the sheaves to let the bight down in which the fork hangs by its sleeve e. ples open, the latch E drops between pins T. The head Yot'said latch, having passed the inclines a, falls behind shoulders f of said inclines, and thereby holds the carrier against the pull otl the hoisting-cord J while the fork is being hoisted again with its load. The latch R then holds the grapple-hooks N open, if not When the grapheld open by inclines b, said inclines being l ing-rope J, at I", in the crib E', on the same shorter than as herein represented as they are sometimes made. When fork K comes up the head O enters bell-mouthed guide P, and is thereby brought into its proper relations with the grapple-hooks. Said head strikes the latch R and lifts head Y up from behind shoulders f, thereby releasing the carrier, so that hoisting-rope J' immediately starts the carrier forward on beam B. The arms Zofthe grapplehooks then escape from inclines b, the grapple-hooks close under head O, and the latch falls on pins T, locking the grapple-hooks, and thus the fork is automatically' connected to the carrier for being carried out to discharge its load and back again to the place for getting another.

I-t will be noticed that the frog is constructed with duplicate inclines a for the latch, and also with duplicate inclines b for the grapple-hooks on the respective ends of the base-plate g, the said duplicate inclines being respectively arranged for working the devices ot' the carrier from opposite directions, the object being to enable the carrier to be run either way from over the load to be discharged, as for delivering hay to a hay-mow either side ofthe wagonlicor. For this purpose the frog is constructed with bevel-tlan ges h to form the inclines b, and

said langes have straight edges t', forming continuous ways irom the inclines b of one end of the frog to those of the other end for the grapple-hooks arms Z to pass along from one end to the other of the frog, and said frog is also constructed with free passage between said tianges for allowing` the T-head Y to shift over from end to end in like manner; but midway between the ends of the frog there is a crossbar,j, projecting as far from the base-plate as it may without obstructing the shifting of the T-head, the object ot' which is to arrest thc T-head, and thereby stop the earxier,if at any time it should fail to stop and the latch should fail to drop, as may happen in case ofthe carrier being jerked back too rapidly or for any other cause. The carrier is to be stopped on its return to the frog by the weight k falling upon a rest, so that positive stopsoil the frog or beam B maybe dispensed with in order that the carrier may be readily shifted on the frog when required without having to detach any parts, as such stops would have to be detached if used. In order to shiftthe carrier from side to side in this way conveniently, it is desirable to have the rope contrived for shifting more readily than it can be done by takingthe hoisting-rope out and reversing it, or taking the carrier from the track and turning it about. For this purpose the knot-cribs E are used. said knot-cribs consisting ot' bar Z, having ears on, pivoted to carrier A at a, also having ange p, with hole through it for the rope, also notched ange q, in which the rope may work and also drop out or in, the said tianges being connected together by side bars, r.

The returning-rope Gr is knotted to the hoistside of the carrier that the returning-rope is on, and when the change is to be made the horse end ofthe hoisting-rope and the weight end ot' the returning-rope are tied together. The knot is then pulled down out'of the crib, and the continuous rope is pulled until theknot passes around through sheaves u and tu, made for passing the knot to the other side of the carrier to be lodged in the crib of that side. rIhe ropes are then untied and connected to lthe. horse and the weight, respectively. It is mainly for this purpose that the carrier is provided with more than one pulley I; otherwise the weight-rope might be hitched directly to the carrier, and the hoisting-rope would work' overone only of said pulleys.

It will be seen that the bell-mouthed guide I? and round-headed fork-top O insure successful operation so far as they are concerned; also, that the latch affords substantial and certain means for locking and unlocking the grapple-hooks, also for locking and unlocking the carrier with the frog, and also for arresting the carrier when overrunning the frog; and it will also be seen that the frog and rope-connecting devices afford simple and easy means of shifting the carrier from side to side of the frog and workingit either way therefrom.

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

l.
