HAY- ELEVATOR.

SPECIFICATION forming part of Letters Patent No. 314,998, dated April '7, 1885.

Application filed November 2?, 1884. (No model.)

T 0 all whom it may concern.-

Be it known that I, PETER F. CHAMBARD, a citizen of the United States, residing at Fayette, in the county of Fulton and State of,

Ohio, have invented a new and useful Improvement in Hay-Elevators, of which the following is a specification, reference being bad to the accompanying drawings.

My invention relates to hay-elevators; and it has for its object to provide improved means for holding the raised load in a stationary position while the same is being dumped.

A further object of the invention is to provide improved means for automatically unlocking the sling from such raised position to allow of its being lowered when the load has been dumped therefrom.

A further object of the invention is to improve the details of construction of the hayelevators in common use, and to provide an apparatus of this character which shall be simple in its construction and effective in its operation.

With these ends in view the invention consists in the improved construction and combinations of parts, hereinafter fully described, and pointed out in the claims.

In the drawings, Figure l is a front elevation of a hay-elevator constructed in accordance with my invention, and showing in dot ted lines the positions of the locking-bars and detents or dogs, respectively locked and unlocked. Fig. 2 is a detail view of one of the locking-bars. Fig. 3 is a detail view of the locking detents or dogs. Fig. 4 is a section of the elevator on the line w as of Fig.1. Fig.

5 is a detail View of the sling. Fig. 6 is a view in perspective, showing my improved carrier complete and in position for operation; and Fig. 7 is a detail view of the sling-lock. Fig. 8 is a detail View of stop J.

In the accompanying drawings, in which like letters of reference indicate corresponding parts in all the figures, A represents the carriage, which consists of the two sides a, of

' similar construction.

Extending upwardly from the sides of the carriage are arms B, the arms on each side being connected by bracerods 12, secured in any suitable manner.

Extending inwardly from each of the arms B is astubshaft, 0, upon which is mounted a roller, C. These rollers are mounted and adapted to travel upon the track D,suspended in any suitable manner, but preferably by hooked arms 6, as shown. A sufficient space is left between theopposite rollers to allow the carriage to pass the said hooked arms,0r other means by which the track may be suspended.

D represents bifurcated arms, each carrying an idler, f, at its outereud, and having an elongated slot at its inner end. These bifurcated arms are pivoted, as shown, near the opposite ends of the carriage, upon shafts g, and are pivoted at their inner ends to a trip-arm, E. This trip-arm E is bifurcated, and midway the length of the bifurcation is provided a transverse pin, 9.

Upon the under side of the track, at suitable points, are provided recesses f. (Shown in dottedlines, Fig. 1.) By the employment of these recesses on the underside of the track the carriage is held in a rigid position while the load is being elevated, from the fact that the bifurcated arms carrying the rollers or idlers are thrown therein, when they are reached, by the weight of the trip-arm E.

On each side of the trip-arm and midway the length of the carriage are provided two shafts connecting the sides of said carriageframe. Upon these shafts are loosely mounted dogs or detents G, the inner ends of which rest in the bifurcated portion of the trip-arm E. It will thus be seen that when said bifurcated trip-arm is raised the pin of the same will strike the inner ends of the dogs and lower the outer ends of the dogs to engage the flanges q of the thimble Q, to be hereinafter referred to.

It is not essential that two dogs be employed when the carriageis to be worked in one direction only; but in order that it may be reversed and worked in the opposite direction the employment of a dog on the opposite side of the carriage is necessary.

H represents a pulley which is suspended from one end of the traclgand passing through this pulley is. a rope, H, carrying at its lower end a weight, f i

I I represent rollers which are journaled upon shafts secured to the sides of the carriage.

Upon the rope H, at a point outside of the carriage-frame adjacent to the roller I, is provided a stop, J, which consists of two sections bolted together, one of said sections having spurs, while the other is provided with recesses to receive the same.

The sides of the carriage-frame are recessed to form hooks, upon which hooks is suspended a bail, K, having downturned ends to fit said hooks. This bail engages or bears against the rear side of the stop and prevents the movement of the rope through the pulley.

Upon the rope between the two rollers I I are mounted two pulleys, j j, below which are arranged anti-friction rollers j mounted in casings J 3 J.

Between the sides of the lower casing is pivoted a hook, L.

Between the sides of the casing J* are pivoted two plates, 1, connected at their lower ends by a transverse bolt.

Near the upper ends of the plates and be tween the same is mounted a roller, m.

Between the sides of the plates 6 is provided a sliding catch, a, which has outwardly-extending flanges to fit ribs on the inner sides of said plates l.

Upon the upper rear end of the sliding catch is a spiral spring which bears against a transverse piece closing the upper ends of the ribs. Said catch extends out beyond the plates Z, and is provided with a hole or opening for the attachment of a cord, 12, which passes up and over the roller m.

Between the lower ends of the plates Z is pivoted a hook, q, the end of which, when raised, is adapted to be engaged by the springpressed sliding catch, and is held in such raised position thereby.

L represents the sling, which is attached to the hook L at one end and to the hook g at its other end. It will be seen that bypulling the cord 1) the sliding catch will be raised and the hook q allowed to drop therefrom. The hook q releases the end' of the sling and discharges the load thereon.

For holding the sling in a raised position until the load is dumped a thimble, Q, having an annular flange, q, at its lower end, is secured upon the rope.

The operation is as follows: The load is placed upon the sling and the hook q placed in engagement with the spring-pressed catch. Draft is applied to the rope, which raises the load, and, as the same nears the carriage, the casings J 3 J" are brought together and strike the trip-arm and raise the same,which,through the medium of the transverse pin located in the same, lowers the dogs or detents, one of which bears against the annular flange upon the thimble, which by the time the trip-arm is raised has passed said dog. In raising the trip-arm the bifurcated arms are lowered from the recesses on the under side of the track. The carriage may now-be moved to the desired dumping-point. when said dumpingpoint is reached, the rope p is pulled, which raises the sliding catch from engagement with the hook g, which drops and releases the sling to discharge the load. As soon as the load has been discharged and the tension on the draftrope removed the weight on the other end of the rope exerts its force and moves the carriage to the other end of the track, the rope being prevented from sliding through the pulley nearest said weight by reason of the pivoted bail engaging the stop. While the carriage is being moved back to its normal position, the rollers on the bifurcated arms slide upon the under side of the track, and, as soon as the recessed portion of the track is reached, said arms engage the same and hold the carriage stationary. The operation above described is then repeated.

It will be seen from the above description that a hay-elevator constructed in accordance with my invention is cheap and simple, and that it is easily operated,and strong and durable.

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

1. The combination, with a track, of a carriage mounted thereon, arms for locking the load in a stationary position, an arm and a pivoted pawl adapted to engage a thimble or like device simultaneously with the upward movement of the arm and the unlocking of the carriage-arms D, substantially as set forth.

2. The combination, with a track, of a carriage mounted thereon, arms pivoted to said carriage and adapted to engage recesses on the under side of the track, a vertically-moving bar connected with said arms, a pivoted pawl having its end connected with said vertically-movable bar, and a flanged thimble on the rope, substantially as described.

8. The combination, in a hay elevator or carrier, with a carriage suspended from and adapted to travel upon a suitable track, of a dog having its inner end resting in a recess in an arm, E, and adapted, when said arm is raised by the load-carrying devices, to be lowered to engage a thimble, Q, on the draftrope, substantially as set forth.

4. In a hay elevator andv carrier, the combination, with a suitable track, of a carriage mounted and adapted to travel thereon, an arm or arms for locking the carriage in a stationary position, detent devices independent of the locking-arms, and a vertically-movable bar adapted to unlock the carriage and lock the load simultaneously, substantially as set forth.

5. The combination, with a suitable track having a recess upon its under side, of a carriage carrying bifurcated arms having idlers, and an arm pivotally connecting the inner ends of said bifurcated arms, and adapted, when raised, to release said arms from engagement with the recess on the under side of the track, as set forth.
