HOlSTlNG-CARRIER.

SPECIFICATION forming part of Letters Patent No. 271,276, dated January BIO, 11883.

Application tiled December 8, 1882. (No model.)

To all whom it may concern Be it known that 1', GU1LE0ED D. HOWELL, of the city of Appleton, in the State of Wisoonsin, have invented certain new and useful Improvements in' HoistingCarriers, usually known as Hayarriersg and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to theaccompanying drawings, and tothe letters of reference marked thereon, which form a part of this specication.

This invention relates to hoistin g-carriers of the class heretofore employed for raising and carrying` hay, and which are provided'with tripping-blocks for the engagement of the hoisting-tackle block. l

The invention has several objects. Among these are, first, to provide a construction in this class of carriers whereby the tripping devices may operate as well at the point of discharging the load as at the point of receiving or hoisting the same, in order that the machine may be used for such purposes as the hoisting, transportation, and lowering of earth in excavations, of shifting freight in freight-buildings, loading and unloading vessels and ears, and distributing freightin vessels and similar situations.

`A second object of the invention is to provide a .construction in this class ot' carriers whereby they are adapted to operate at either side of a tripping-block without the necessity ot reversing the carriage in the beam or way.

A third object of the invention is to provide for a change ot' power and speed in the hoist.

To these and other ends which will further appear my invention consists in the matters hereinafter set t'orth, and pointed out in the appended claims. v

In the drawings, Figure l isa side elevation ofthe carriage, together with a stationary tripping-block and a fragment of the beam forming the carriage-way. Fig. 2 is a view in elevation of one ofthe plates ofthe carriage, having the locking devices thereto attached, and showing the position of these devices with reference to each other when engaged with the hoisting-block, and also showing the peculiar construction ofthe tripping-block. Fig. 3 is a Y view similar to that shown in Fig. 2, butillustrating the locking devices in their` position forms part of the locking devices, and which also serves as a bracefor the plates of the carriage. Fig. 6 is a side elevation of the carriage and hoisting-block, in which the latter is provided with two pulleys, and the hoistingrope is arranged to operate in conjunction with said double pulley-block and thetwo pulleys of the carriage to give increased hoisting-power. Fig. 7 is an end elevation ot' the devices constructed and employed as shown in Fig. 6. Fig. 8 is a general view, in side elevation, of the entire carrieras applied to shifting freight.

A and A are two opposite and parallel plates, forming the body of the carriage R, said plates being respectively provided with the arms a and a', to the upper extremities of which are attached the wheels A2, intended to travel on the suspended beam or way B.

C C are two loose pulleys mounted between the parallel plates A and A at opposite ends 0t`. the carriage, as clearly shown in the drawings; and D is a hoisting-block, provided with a pulley or pulleys, d, a hook, d', at its lower end for engage-ment with the article to be raised, and a loop or yoke, d2, at its upper end for engagement with the locking devices ot' the carriage.

E is a ropetrained over the pulleys C C and beneath the pulley d, and also, in practice, usually trained over another pulley, B', Figs.

`G and S, attached tothe beam B in position to give the rope E the substantially horizontal direction shown in several figures of the drawings as the same passes from the carriage. Said rope is further usually trained beneath a pulley or snatch block located at or near the ground or floor, whence it leads to the team or other motive power by which the-apparatus is worked.

The devices provided in the carriage for engaging and holding the hoisting-block D are located between the pulleys C U, and they consist essentially of the parts F, G, and H. The

part F is an angular casting (shown detached in Fig.5) embraced lirmly between the opposing plates A and A byv means of the tie-bolts,which IOO pass through said plates from one tothe other. l that as the lateral projection h2 on the dog H Said casting F has its lower end, f, formed to serve as a stationary hook projecting in a substantiallyhorizontal but somewhat downwardly inclined direction, as shown in Figs. 2 and 3, and being thin enough at this end to stand free andclear from the side plates, A and A', and midway between them, whereby it may enter the yoke or eye d2 of the hoistingblock.

G is a tripping-hook centrally pivoted at g3, and adapted to swing with its lower end or point, g,into proximity with the end f of the part F, so as to enter the eye d2 of the hoisting-block, and tol thereby sustain or assist in sustaining the latter in place when raised. Said hook G is provided with a projection, g', located above the point y, against which projection the top of the yoke d2 strikes in being raised, so as to thereby rotate said hook G on its central pivot, g3, and thus bring the point g within the yoke. The upper end of the hook G is provided with a lug, g2, which, when the hoisting-block is released, is drawn forward and downward against the upper end of the fixed part F, and is thereby held in the position shown in Fig. 3, with the projection g extending in the path of the yoke d2 of the hoisting-block, so as to be struck and lifted, as above described, when said hoisting-block is raised. Said projection g2 is also intended to engage with thelocking-dog H,which is pivoted at h, and is provided with a depending lug, h', which lug drops iu front of the projection g2 of the tripping-hook G when the latter is swung over by the hoisting-block, and thereby rmly holds said tripping-hook in engagement with the yoke or eye d2 of said hoisting-block, as shown in Fig. 2.

I is a trip-block secured to the beam B at any desired point beneath which the load is to be taken or discharged. Said tripfblock is provided with a lateral inclined groove, t, being usually inclined upward from both its opposite ends to the middle, as plainly indicated in Figs. 2 and 3. Engagement of the'dog H with the tripping-block l is eEeeted by means of alaterally-projectinglug or pin, h2, thereon,

(seen in Fig. 4,) which'pin enters the groove i.

again allow the dog to descend.

When the groove isdoubly inclined said pin may enter from either end, according to the direction in which the carrier approaches the trip-block. In order tohold the dog H at a proper elevation to enable the pin h2 to enter the groove i of the trip-block l, said dog is provided with a second pin, h3, Fig. 4, ex tending laterally therefrom in position to rest on the upper edge ofthe adjacent carrier-plate A, and thus operating as a stop to limit the downward movement of the dog. The depending flange h' ot' the dog H is constructed to rest on the upperend, g2, of the hook G when the latter is tripped, as shown in Fig. 3, and thereby holds the dog H raised. Being thus sustained, the dog, by its pin h2, is permanently held to the trip-block, and the carriage is retained in -place until the hoisting-block is raised and the hook G swung over so as to It is obvious .in the entering angle ot' said part F.

passes out of the groove t' of the trip-block the said dog is forced downward by the upper wall of the groove, so that full and reliable engagement of said dog with the hook G is insured. y t

For the purpose of directing the yoke or eye Z2-fairly into position to be engaged bythe hooks of the carriage, the plates A and A' are cast in form to provide a flaring entrance, which receives and guidesthe yoke or eye d2 to its proper place.

rIhe stationary part F (shown detached in Fig. 5) is provided with lateral flanges f', which are seated between shallow ribs' a2, cast on the inner faces ofthe plates A and A', and,

as here shown, is additionally held in place by the tie-bolt a3 for the plates A and A', located Being clamped firmly in place between the opposing plates, this part F serves, in conjunction with the bolt a3 and bolts a4,joining said plates, as 1 from either side of the tripping-block, and in this respect itv dil'ers essentially from the carriages heretofore constructed, which have been 4provided with but a single pulley C, and have required to be reversed or turned around on the supporting beam or way B in order to change their running direction. The rope E, as applied to the carriage having a single pulley din the hoisting-block D, is made fast at one end, say, by a simple knot,e, which draws against the tie-bolt a4, adjacent to the pulley C. To work the carriage on the way B at the opposite side ofthe tripping-block l from that at which it has been working, it is therefore only necessary to draw the now fast end o't the rope out and bring the opposite and similarlyknotted end into the same position relative to the opposite pulley C. The presence of a second pulley C on the carriage, which is new in the device here presented, also allows a double sheave or pulley block, 1),*to be employed,as illustrated in Figs. 6 and 7. In this case the hoisting-rope is tied through one ot' the holes a5 of the plate A or A', or is otherwise secured to the body of the carriage, and is thence carried under one of the pulleys d of the hoisting-block, then over one ofthe pulleys C, then beneath the second pulley d, and finally over the second pulley C. To provide in this case for shitting the working position of the carrier from one side to the other ot' the trip-block I, the tied end of the' rope E is released and drawn out from the hoisting-block D, and the opposite end ot" the rope is inserted from the adjacent side and tied in the otherk hole a5. For the purpose ofthis change from a single to a compound tackle both asingle and a douhle block I) may be provided, or the IOC IIO

pulleys d may be changeable by means of' a removable pivot-pin for said pulleys.

In the construction of the trip-block I with a doubly-inclined groove, t', as shown and described, it is practicable to locate several ot' said 'blocks at dilerent points on the beam B. and to carry the load past as many as desired by throwing a long-handled inverted-V-shaped hook (in the hands of an attendant) over the horizontal part ot' the rope E at a point close to the carriage as the latter approaches a tripblock which it is desired to pass, and pulling downward with sufficient force to bind the rope, and thus prevent the load from falling while the dog is lifted and passes through the groove of the trio-block, and while, therefore, the load would otherwise be free to fall. This operation is found very convenient in many situations-as, for example, in discharging as- -sorted matters at different points along the adapted to be tripped by a block, I, at each end ofthe way. Fig; 8 shows the extremities vof a way, B, provided with blocks I at points where it is desired to' lower the hoisting-block, either for the purpose of receiving or for discharging a load. As shown in this iigure of the drawings, the load is being taken from a point at the left and being' delivered at a point at the right end of the sheet. I n theicase of a carrier system of the description shown in Fig. 8, located permanently in a freight-building or similar situation, the trippin g-bloclis at the extremities of the way may be each provided with a groove, t', inclined only one way,there being no need for the outer o block having` the doubly-inclined groove 'i will have several advantages when used in connection with a carriage in which the lockingdog is adapted to engage therewith, though said carriage have but one pulley C, as here,

tofore constructed, and needs to be reversed when shifted from one end to the other of the way. In such case the block I should be provided with a groove on each side, and should depend centrally ot' the beam, so asto have the same relation to the carriage whichever way the latter is turned or approached. Manifestly, working the carriage between two tripping-blocks attached to the way is an operation equivalent to working the carriage on both sides of a single tripping-block, and requires in the carriage and tripping devices es sentially the same features ofconstruction;

or, in other words, a carriage adapted to work between two separated tripping blocks is adapted to work on bothsides of asiugle triptially Aas described.

ping-block having a doubly-inclined groove, i. It is ofcourse understood that theV carriage is drawn forward upon the way by the hoistingrope E after the latter has drawn the hoisting-block into en ga gement with the catching devices on the carriage therefor, and that said carriage is returned along the way by means of an auxiliary ropeor equivalent device, which in Fig. 8 is shown as being attached to the carriage, and is lettered c. In the case of hay-carriers this returning-rope e is ordinarily that which is connected with the hay-fork, and which also serves to unlock the said fork` for the purpose of releasing theh ay therefrom.

I claim. as my invention- 1. In a carrier of the general description shown, the combination ot a way, two separated trip-blocks attached to the way, and a carriage provided with devices for catching and releasing thehoisting-block, constructed to work with both trip-blocks, substantially as described.

2. In combination with awayhaving a suitable trip-block attached thereto, a carriage provided with devices f'or catching and releasing the hoistingbloek, adapted to coact with the ,tripblock when approaching the latter from either direction, and two pulleys, C, for the hoisting-rope, substantially as described.

3. In combination withthe way, a trip-block having a lateral inclined groove, t', and a carriage, R, provided with devices for catching and releasing the hoisting-block D; whereof the locking-dog is provided with a lateral projection, h2, for engaging said groove, substan- 4. The tripping-block provided with adoublyinclined lateral groove, fi, in combination with the way, and with the carriage provided with mechanism for engaging the hoist, whereof the loekingdog is constructed with a lateral projection titted to enter'said groove substantially as described, and for the purposes set forth.

5. In combination with the pivoted hookG ot' the mechanism belonging to the carriage, said hook being provided with the projection g2, the pivoted dog H, having a lateral pin, h", and constructed to rest upon the hook G when said dog is elevated, and the trip-block I, :affixed to. the way, and hav-ing an inclined lateral groove, t', for the reception of the pin h2, substantially as described.

6. In combination with the carriage provided with two pulleys, C G, ahoisting-blocli, D, pro vided with two pulleys, d, and the rope E, substantially as and for the purposes set forth.

In testimony that I claim the foregoing as my invention I affix my signature in presence ot' two witnesses.
