HAY-CARRIER.

SPECIFICATION forming part of Letters Patent No. 515,296, dated February 20, 1894. Application filed October 17, 1891. Renewed [lanuary 18, 189A. Serial No. 497,330. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM LOUDEN, a residentof Fairfield,in the countyof Jefierson and State of Iowa, have invented certain new and useful Improvements in Hay-Carriers and I do hereby declare the following to be a full, clear,

and exact description of the invention, such as Wlll enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in hay carriers,its object being to provide a hay carrier which shall be simple in con struction, comprising a small number of parts; one WhlCll shall be easy to manipulate and be effectual in the performance of its functions.

With these objects in view the invention conslsts in certain novel features of constructlon and combinations and arrangements of parts as hereinafterset forth and pointed out in the claims.

In the accompanying drawings: Figure 1 is a side View of a carrier with front side removed and part of the block E broken away. Fig. 2 is a cross section of the track A, hooks H, H, casting I and stop L. Fig. 3 is a detail view illustrating the groove 0. Figs. 4, 5 and 6 are sectional views of different forms of same. Figs. 7 and 8 are views of modificatrons of the keyl and stop L. Fig. 9 is a vertical section through the construction shown n Fig. 8. Fig. 10 is a sectional view showlng adjustable stop L. Fig. 11 is aview illustrating a modification of the block E.

A represents a T-rail upon which the carrler runs. The carrier is composed principally of two side pieces a suitably joined to-' gether so as to straddle the track A, and provided with sheaves B, B, and track rollers O, C. A draft rope D is passed over the sheaves B, B, and under the sheave F of block E in the usual manner. The block E is fitted with semicircular portions, as for instance loops E (Fig. 1) or semicircular ribs E as shown in Fig. 11, one on each side of its upper end.

' Grappling hooks H, H, are pivoted to opposite sides of the carrier frame,one to each side and opposite each other, and are provided with inwardly extending Webs or flanges G, G. Power being applied to the end D of the draft rope, the block E will be drawn up until its upper end comes in contact with the flanges G, G, and forces the lower points H, H, in under the loops E of the block E, and the upper ends H H will be spread apart and held in this position by a wedge or key I sliding or dropping in between them, as will be hereinafter explained. The block E will now be securely held by the hooks H, H, and yet will be entirely free to swing back or forth on the points H, H, of the hooks H,

H, within the limits of the loops E, to accommodate the line of draft in carrying a load along an inclined track, or in dragging a forkful of hay over the hay in a partially filled mow. By this means all side strain on the block E is obviated, and one end of the carrier cannot be tipped up on the track, as is the case when the connection between the block E and the grappling mechanism is more or less rigid. It will be observed that these lips or loops E, E, are parallel or approxi mately parallel with the periphery of the sheave F, and concentric with the axis of the sheave so that the frame of the block will be free to swing without affecting the position of the sheave.

The key or, wedge I is preferably made hollow so as to straddle the track and with forked ends to project up above the track and engage a stop secured to the upper part of therail. There are different ways of constructing the key I, but the form preferred is shown in Figs. 1 and 2, in which the key I is adapted to slide horizontally in the frame of the carrier, and is provided with two sets of prongs or forks J and K which engage the laterally projecting ends of stops L secure to the upper part of the rail A. a

The casting constituting the wedge or key I is provided with bosses or stud pins M, M, which are adapted to slide in grooves 0, formed in both sides of the carrier frame 0pposite each other. The central part of this groove or guide 0 is placed horizontally, while the ends 0 are depressed so that when the bosses or stud pins on either end of the casting I run into this depressed part of the groove or guide 0, this end of the casting I will drop sufficiently to let the prongs or forks above it pass under the stop L. WVedge or key I is also fitted with a notch N at or near its center into which the upper ends H H of the grappling hooks will enter, and hold the casting I in a central position, as indicated by dotted lines in Fig. 1. The stop L being now between the forks J and K the carrier will be held stationary on the track. Power being applied to the draft rope at D, the car-' nor will be drawn along the track until the fork J comes in contact with the stop L. The ends H H being in the notch N, the casting I, will be held from sliding in the groove 0 until the block E comes in contact'with the flanges G, G, and frees the key or wedge I by raising the hooks H H out of the notch N. Key or wedge I will then be drawn into the position shown in full lines in Fig. 1 and freed from stop L, while it will also be securely wedged in between the upper ends H H of the hooks H, H, and their lower ends H, H, be held securely under the loops E of the block E, thus securely holding the block E, with its load, to the carrier while it is traversing the track. The carrier being drawn back by a pull on the draft rope D (or otherwise) the prong .I will pass under the stop L, which will engage the prong K and slide casting I backin the groove 0 until hooks H,

H, drop into the notch N, which will release block E from hooks H, H, and lock the carrier to the track, as-already described. In

order to make it more certain in its operation and prevent the weight of the free end of the draft rope D from holding the block E up against the flanges G, G, of the hooks H, H, and prevent their upper ends from dropping into the notch N as it passes by them, I use coiled springs S, S, so applied as to force the upper ends of the hooks H, H, in and the lower ends out.

I am aware that springs have been applied to the grappling hooks of a hay carrier, but

always for the purpose of making the hook take hold of the block E. I use mine in the opposite way, and simply for the purpose of over-balancing the weight of the free end of the rope (D) and preventing it from holding the hooks H, H, out of the notch N, in which case the carrier would run by the stop L. Any form of spring may be used for the purpose.

The groove or guide 0 may be constructed in different ways: first, by letting it into the sides of the carrier frame as shown in Fig. 4; second, by forming it entirely on the inside of the carrier frame by means of two parallel flanges, as shown in Fig. 5, or, third, by using a single flange O as a guide or way and making the boss M forked to fit over it as shown by M'in Fig. 6.

It is evident that the carrier, by changing the attachment of the motive power from one end of the draft rope to the other, will work in either direction from the stop L. But if desired it can be converted into a one way carrier by simply placing a bolt or stops X at either'end of the horizontalpart of the groove or guide 0, so that the casting I could not While I consider the form of the key I shown in Figs. 1 and 2 the most preferable form, still I am aware that other forms can be used to advantage; That shown in Fig. 7 can be used without departing from the fundamental features of my invention. Like the other, the key I is made hollow to straddle the track with the forked end extending up to engage a stop secured to the upper edge of the track, but it is adapted to slide up and down perpendicularly in the frame of the carrier. The stop L is provided with inclined'flanges R, B, (Fig. 8) which engage the inwardly projecting points P, I, and lift the wedge I out of the corners H H and allow the hooks to swing and release the block E, the hooks H, H, holding the points P, P, of the wedge I up in the central part of the inclined flanges R, R. The block E coming in contact with the flanges G, G, turns the hooks H, H, so the wedge I can drop down in the corners H H thus locking the block E fast and freeing the carrier from the stop L. The fundamental feature in both these constructions is the forked (or hollow) key I (or I) arranged to straddle the track, with its forked ends projecting up to engage a stop secured to the upper edge of the rail A, so that the lower edge of the rail may be left entirely smooth andclear of all obstructions. By this means the lower part of the carrier can be drawn up closer to the rail, and a very light but strong and compact carrier can be constructed.

The stop L is made in two pieces and is bolted or otherwise clamped to the upper edge of the central part of the rail A. By this means it can be easily and quickly applied to or removed from any part of the rail and no drillingor any other previous preparation I form the stop as shown in Fig. 10, in which the piece L forming the stop is placed in a slot T of a frame T, which is clamped to the rail A, the piece L being held in its place by means of coiled springs u, u. The coiled springs to encircle fingers u,.which depend-- from arms a projecting laterally from the frame T, said fingers being adapted to enter perforations w in the stop L; When the stop L is approached by the highest forks of the casting I from the outside, it will slide up the incline of said fork and over it, to pass it; and, the frame T- may be fitted with a sheave V over which a cord Y attached to the stop L is passed, so that the stop L may be raised out of the way by pulling on the cord Y.

Although I have shown anddescribed in this application a stop located on the upper edge of a track rail, in connection with a carrier, and a dog adapted to engage the stop and be operated thereby, I make no claim in this application to this construction broadly as the same forms the subject-matter of appgcgtion, Serial No. 450,359, filed October 29,
