PHILIP A. MYERS, OF ASHLAND, OHIO.

HAYNCARRIR.

SPECIFICATION forming part of Letters Patent No. 291,85?, dated January 9, 1884.

(No model.)

T0 all whom, t may con/cern:

Be it known that I, PHILIP A. MYnRs, of Ashland, in the county of Ashland and State of Ohio, have invented a new and useful Improvement in Hay-Carriers; and l do hereby declare that the following is a full, clear, and exact description of the same.

My invention is an improvement in haycarriers of that class adapted to run upon an elevated track to be held by a suitable catch while raising the load, to automatically release the latch when the load is raised, and to hold the load suspended during its horizontal movement.

My object may be stated in general terms to be the improved construction of the parts, whereby they are rendered more simple, inexpensive, and durable, and whereby, also, every operation is made more certain and effectual. I have aimed to avoid the use of springs and to free the latch from any defective operation by reason of the swinging of the carrier from side to side. The carrier is adapted specially to run upon a track composed of a rod or wire rope, but may be used also with a bar or equivalent form of track.

In the accompanying drawings, Figure l represents a side elevation of my improved carrier with a part of the track, the carrier being latehed in position to receive a load and the hook-pulley partly lowered. Fig. 2 represents the carrier partly in longitudinal vertical section in the same position, but with the forked lock raised and the latch partly released. Fig. 3 is a section of line x x of Fig. 2. Fig. et is an end view of the track, showing the loop or detent which holds the latch and operates the dog. Figs. 5 and 6 show modifications hereinafter explained.

The body of the carrier is composed of a pair of bent fiat bars, a a, and they are con nected to each other with distanoe-piecesby means of the bolts on which the sheaves and other parts are pivoted, and are separated far enough to allow space for the latch and dog hereinafter described. The frame is suspended from the track by means of pairs of straps l and 2. Of these straps pair l, which is on the rear of the carrier, is riveted near the bend and carries a sheave, 3, on its upper end. The

other pair is riveted on each side to the forward end of the carrier with a sheave, el, above, to run upon the track, and below a sheave, 5, for the hoisting-rope. The bars a may be bent either in the shape shown in Fig. l or in that shown in Fig. 5, the difference being simply that in the latter the bent end is projected farther forward. iWithin these bent ends is pivoted a bell-crank lever, A. It has ahollow or grooved shank, b, adapted to receive the rope, and an arm, c, adapted to operate the latch and to be held by the dog when the load is hoisted. The latch and dog are shown in the side elevation, partly in dotted lines. The latch (marked B) is a flat bar pivoted upon the bolt 6 and extending rearward between the bars a a. A hook on its rear end engages with the loop or detent D, fixed to the end of the track where theload is to be raised. The latch is formed with a bend, 7 (shown more clearly in Figs. l and 6,) which lies in the path of the broad end S on the end of arm c of the bellcrank lever, so that as the lever is swung up by the elevation of the load the arm c, with its broad end, comes into the position shown in Fig. Z, and raises the latch, thus releasing` the carrier and permitting it to move forward with its load. Also, between the two bars a a and on the same pivot with the latch is pivoted a dog, E. Itis made of a flat bar ofmetal likethe latch, and has its free end bent, as shown more clearly in Figs. 2 and 6. As it is also in the path of the broad end of the arm c, it is also raised by the movement of that arm when the weight is elevated. The lower edge ofthe dog is notched to form a shoulder, 9, and, being free to fall, drops when the end of the arm c has passed the notch and dogs the bell-crank lever, thus supporting the load in an elevated position, ready for movement upon the track.

It will be observed that the parts are in such position that the arm c first passes behind the shoulder of the dog shown, so that it is in position to be retained securely in place, and afterward strikes against the ineline 7 and lifts the latch, so that the load is locked securely in place before the carrier can start, making action'of thc parts absolutely certain. Further, the dog, after the carrier has left the detentl or loop, cannot be inter- IOO the dog is provided with an upturned end,`

10, which rides up on the detent and lifts the shoulder 9 away from the end of the arm c, thus allowing the hook to drop. The detent D may be formed, as shown in Fig. 4, conveniently to clamp the track at any desired point. As will appear more clearly in Fig. 2, the lifting` incline IO of the dog is a little nearer to the carrier than the shoulder of the latch. This permits the carrier to recede sufciently from the detent before the latch takes hold to allow the dog to drop and be ready to operate on the bell-crank lever when theload is raised.

In Fig. 5 Ihave shown the bent ends of the bars a c, which formthe body of the carrier, as extending far enough to the front to receive the sheave of the i'orlc-block, so as to allow it to rest thereon during the movement of the carrier. The only difference between this form and that shown in Figs. l and 2 is that in the latter iigures the load rests upon the shank or arm ofthe bell-crank lever. In the form shown in Fig. 5, the weight rests upon the carrier and brings no stra-in upon the bellcrank lever o'l" the dog.

bell-crank lever. In order to separate the latch and dog, I have provided a thin flat strap, F, Figs. 5 and 6, which is inserted between the latch and dog and bolted below to the frame and above to the rear pair of straps. In orderto cause the levers to act with promptness and certainty, I may also addaspring, g, which is fixed to a stud on the bar F, or to any other convenient point, and extends forward to bear upon the upper edges ofthe latch and dog.

It will be observed that the general construction of the carrier is simple and of few parts, and in this respect is new. The construction and dog I regard also as an important part of my invention. Incidentally to the construction of the carrier is the important feature shown ,in Fig. 5,whereby the load is supported on the carrier itself, and requires only Manifestly, the pul- .ley 5 should be higher than the pivot of the I between the bars ofthe carrier, combinedwith dog are not new, and I do not broadly claim such a carrier.

I claim as my inventionl. A hay-carrier consisting of two bent side bars properly connected with hangers and supporting-sheaves, a bell-crank lever pivoted on the bent ends ofthe bars and connected to the hoisting-rope passing overa pulley onthe earrier, a latch adapted to catch over a detent on the way, and a dog to hold the bell-crank lever, the latch and dog being constructed to operate in connection with the detent, substantially as described.

2. The combination, in a hay-carrier, of a latch and dog pivoted within the carrier, a bell-crank lever connected to the hoisting-rope and having an arm adapted to operate a latch and dog and be held by the dog, and a pulley for the hoisting-rope adapted to throw the lever-arm against the dog and latch, al1 substantially as described.

3. The combination, in a hay-carrier, of a bellcrank lever connected to the hoisti 11g-rope, which is arranged to run over an elevated pulley, 5, an arm ofthe bell-crank lever, and a dog, E, iit-tedv to be lifted by the arm and by the detent on the way, all substantially as described.

4. 'The eombination,in a hay-carrier, of hoisting devices and a dog, E,adapted to belifted by the hoisting devices, and a detent adapted to raise the dog, all substantially as described.

5. In ahay-earrier,thelatch and dog pivoted a detent, D, and adapted to operate in connection with the detent, substantially as described.

6. The con'ibination,with the described haycarrier, oi' the latch B and dog E, both having inclines,\vlie1eby it is lifted by the hoisting devices and by the detent, all substantially as described.

7. The combination of thelatch and dog with the hay-carrier supported by sheaves on a track, and the detent D, having semicircular bar, all substantially as described.

8. In combination with the latch and dog of the described carrier, the separating-strap F, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
