HAY-CARRIER.

sPEoIFIcATIoN forming part of Lettere Patent Ne. 525,425, aeteei september 4, v1894..

Application tiled May 19,1894. n

have invented a new and useful Improvement v 1n Hay-Carriers, of which the following is a specification. e

This invention relates to carriers in which a brake or clutch is used to grip or catch and hold the hoisting rope where it passes over' the sheaves in the carrier frame, and thus prevent the load from dropping down from the 'carrier as it traverses the track; and it consists of improved means for releasing this brake or clutch from the rope, and in holding 1t released while the tackle is being lowered from or elevated to the carrier.

It further consists of certain combinations and arrangements of parts set forth in the following specification and claims and shown in the accompanying drawings. v -Y In the drawings Figure l is a side elevation of a carrier embodying my invention, the front side of ythe' carrier frame being removed to give a better view of the working parts. Fig. 2 is a vertical section drawn on the line of Fig. 1. Fig. 3 is a horizontal section drawn on the line Z, Z, of Fig. 1. Figs. et and 5 are side elevations of modified forms of carriers embodying my invention, the front sides of the carrier frames being removed to give 'a better view of the working parts.

Fig. l shows a carrier A, mounted in the usual way upon a track B, which may be constructed in any suitable manner. is provided with sheaves orropewheels C over which the hoisting rope D is passed, and in the loops of which pulley blocks E are hung, all inthe usual manner.

' A stop block F having inclined faces G and catch shoulders I-I, is secured to the upper edge of the track B.v

Brakes or clutch pawls I are pivoted in the carrier frame by means of a bolt J, and are arranged to catch and hold the rope D upon the sheaves G.

K ie .e yoke having e. limited ver-tical ending movement in the frame of the carrier, its arms extending up by the track B. Rollers or wheels L are mounted upon the upper ends of the arms of the yoke K and are adapted to run up on the inclined faces G and lift the yoke.

' these forks,

The carrier seriei No. 511,811. me model.)

The upper part ofthe yoke is passed through a portion a, of the carrier frame which is extended up to support it, while the lower end is provided with a pair of downwardly projecting slotted forks M.

The bolt J upon which the clutch levers I are pivoted, is passed through the slots in so that the yoke K will be secu'relyy supported laterally, but will have free vertical movement in the frame of the carrier to the extent of the slot in its lower end.

Horizontal branches N are extended a short distance on each side of the yoke so as to be parallel with the clutches I. Links O are connected to these branches and also to the clutches. It will be seen that by this means when the rollers L run up the incline facesGr and lift the yoke K the clutches I will also be lifted off the rope D, which will thenbe free to run over the sheaves C, and the tackle may be lowered for a load. l

In order to hold Vthe carrier stationary at the stop F and the clutches releasedfrom the rope while the load is being elevated, dogs P are pivoted atQ in a portion of the frame of the carrier which is extended out to receive them. These dogs are adapted to engage shoulders R on the yoke K, and hold it in its elevated position, so that the rollersL mounted in the upper ends of the yoke cannot pass underthe shoulders H or out of .the stop F in which case the carrier will be held from moving along the track, and `the clutches I will be held released from the rope.

Abail S is connected to the dogs P and when the' load is elevated this bail will be lifted by the tackle so as to throw the dogsP out of engagement with the yoke K, and permit it to drop down and pass out of the stop F so the carrier can move along the track. The clutches I will now drop on the rope and grip it upon the sheaves C, so as to prevent 'the tackle from running down from the carrier. Y

The carrier being returned to the stop F the rollers L will run up one of the inclines G and lift the yoke K and the clutches Iconnected to it, so that the tackle will be allowed to descend, and at the same timethe dogs P will ICO engage the shoulders R on lthe yoke K, and

hold the rollers L from passing outl `of the stop. rlhe operation may be repeated at will.

Itis evident that the carrier may be operated either way from the stop F, andthe c lutch pawls I being set in opposite directions will grip and hold the rope on both sides of the elevating tackle. It is not essential however, that the details shown in Figs. l and 2 above described shall be strictly adhered to. I consider this the preferable form but am aware that several modifications may be made without departing from the scope and spirit of my invention. Two of these modifications are shown in Figs. 4 and 5.

Fig. 4 represents a carrier A designed to operate in either direction upon the track and is substantially the same as that shown in Fig. 1, except that the clutch T is made in i one piece. It has a vertical movement in the frame of the carrier, and is designed to drop on the rope between the sheaves C and hold it in both directions. TheyokeU has alower forked endwhich straddles the clutch T, and is connected to it by means of the bolt V passing through the slotted hole Y.

It is desirable to have a little slack in the connection between the lifting device and the clutch, because dilerent sized ropes may be used in the carrier, and if the connection was rigid a large sized rope might not permit the yoke to descend low enough to pass the rollers out of the stop F nor permit them to enter it. This is amply provided for in the link connection shown in Fig. l. In Fig. 5 a one way carrier A2, is shown having only one hinged clutch pawl l2, and a single lifting link K2 connected to the clutch and passed up on one side of the track tothe stop F. This will answer the same purpose as the yoke K.

The yoke passing up around both sides of the track is the` preferable plan but the form of lifting device shown in Fig. 5 is within the limits of my invention. The stop may also be secured to the lower edge of the track, (as is commonly done) and the lifting device extended up only suiiciently to engage the stop located in that position, without exceeding the scope and spirit of the invention. It is preferable however, to place the stop on the upper edge of the track and extend the lifting device up around the track to engage the stop, as shown in the drawings, because by so doing the hoisting tackle can be drawn up closer tothe track and space will thereby be economized in the operation of the carrier.

The tripping bail S shown in Figs. 1 and 4 is dispensed with in Fig. 5, and a combined dog and trip lever P2, is used instead. It is hinged to the carrier frame at e, and is constructed to straddle the clutch pawl I2, the front side being cut away in the drawings.

The elevating tackle is adapted to lift the lower end P3 and throw the upper end P4 out of engagement with the shoulder Pt2 of the lifting link K2. W'hen the lifting link is raised by the stop F, the weight of the lower end P3 will draw the end MP4, under the shoulder R2.

The roller L shown in Figs. 1 and 4, is also dispensed with, and an ordinary horizontally projecting finger L2, is used to slide up the incline G and catch against the shoulder I-I of the stop F.

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