SPECIFICATION forming part of Letters Patent No. 472,175, dated April 5, 1892.

Application liled October 2, 1891. Serial No. 407,495. (No model.)

To aZZ whom t may concern.-

Be it known that I, WILLIAM LOUDEN, of Fairfield, in the county of Jefferson 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 will 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, the object of the invention being to produce a hay-carrier and tripping mechanism thercfor,whereby said carrier may be automatically locked and released.

A further object is to construct a hay-carrier and trip mechanism in such manner that the sling will be automatically released when the carrier engages said tripping mechanism.

A further obj ect is to provide means whereby hinged latches maybe operated'to release a hay-carrier by means of a cord or bar passing through the rail upon which the carrier runs.

A further object is to provide an improved mechanism for carrying and operating the brake-shoes.

A further object is to improve the general construction and the details of a hay-carrier.

vA further object is to produce a hay-carrier which shall be simplein construction and effectual in the performance of its functions.

Vith these objects in view the invention consists in certain novel features of construction and combinations and arrangements of parts, as hereinafter set forth, and pointed out in the claims.

In the accompanying drawings, Figure l is an elevation of the device. Fig'. 2 is a similar view with part of the frame removed. Fig. 3 is a plan View of the tripping devices. Fig. 4 is a view of the hinged latches of the tripping mechanism. Fig. 5 is a separate view of one of the clevises which carry the brakeshoes. Figs. 6, 7, and` 8 are detail views.

A represents a frame or housing composed of two plates a a, held together by means of suitable bolts and spaced apart by means of sleeves encircling said bolts. Securely bolted to the plates a a of the frame A-one at each end of each plate-are upwardly-extending arms or hangers B. Each arm or hanger B is made of a single piece of metal having stout flanges b b, and said flanges are connected by a light web b, the inner edges of the arms or hangers B being rounded so as t0 prevent the engagement of the arms with slivers or joints in the track. By this construction an arm or hanger will be produced which is comparatively light in weight, still possessing the requisite amount of strength. The lower ends of the arms or hangers B may be contracted somewhat and secured to the frame A by means of a bolt b2, said bolt b2 serving to secure the lower ends to two diametrically-opposite arms or hangers B, said bolts b2 also serving as shafts for two pulleys C C, mounted in the ends of the frame A and between the plates d a thereof. The arms or hangers B are also secured to the frame A in pairs by means of bolts passing through the arms and frame at points between the ends of said arms or hangers, and said bolts may have collars encircling them which serve to maintain the upper part of the frame A properly spaced apart. Each arm or hanger B is provided with two ears b3, having perforations for the reception of lugs b4, projecting from the plates a a of the frame A, and thus assist in preventing endwise movement of the arms or hangers. The upper corners of the arms or hangers B are made somewhat flaring, and in said flaring corners perforated bosses bl are formed. Secured in each perforated boss bl is a pin b5, which projects inwardly from the arm B and constitutes a bearing for a roller h6, adapted to run upon an elevated track D. Thus it will be seen that each arm or hanger B is provided with two rollers h6, and there being four arms or hangers B the carrier will be supported upon eight rollers h6, four running near each edge of the track or rail D. The upper edge of each plate a of the frame Ais made with four shoulders or stops c c c c', with which the latches of the tripping mech` anism are adapted to engage to lock the carrier to the track or rail D.

In constructing the tripping or locking mechanism a plate E is secured to the under side of the rail D and provided at each end with perforated bosses e for the reception of the journals e of two latches or locks E',

whereby said latches or locks will be hinged IOO to the plate E. The plate E is also provided at its center with a hollow projection or arm E2, the function of which will be explained farther on. The latches E are each provided with an inwardly-projecting arm e2, bifurcated at their inner ends and adapted to embrace loosely a bar e3, which extends loosely through a perforation in the rail D, said bar ea having a cross-head e4 adapted to project under the inner ends of the arms e2. In order to make the bar e3 light and to save metal in its formation said bar may be made in the form of a loop or link, and it is provided at its upper end with an eye e5 for the reception of one end of a cord or rope e", whereby to operate it to lift the latches or locks E', for a purpose hereinafter described. The cord or rope eG is extended upwardly from its connection with the bar e3 and passed over a pulley f, supported in a bracket f secured to the rafters of the barn or other structure. The bracket f is preferably made as shown in Fig. G-that is to say, two arms f2 are provided and disposed at an obtuse angle relatively to each other and perforated for the reception of fastening devices, whereby to secure the device to the rafters. Ears f3 proj eet laterally from the arms f 2, and are also perforated forthe accommodation of fastening devices. The two arms f2 are connected by two curved arms f'1 f4, and at the apex of the curved arms f? the pulleyf is jo'urnaled. This construction produces a light, strong, and cheap bracket for the support of the pulley f, and one which is adapted to conform to the angle formed by the rafters of the building in which it is located.

The latches E are each provided at each side with prongs g, each having a curvedunder face or edge, and adjacent to these prongs shoulders g" are formed. The shoulders g are adapted to engage the stops c c c c', and are maintained normally in engagement with these stops by means of springs gG inserted between the latches E and the plate E, and it is the purpose of the bar e3, hereinbefore described, to release thelatehes E from these stops, said bar serving to release both latches simultaneously. It will be seen that when the carrier-frame is locked by the latches or locks E the carrier will be prevented from movement in either direction,the shoulder g of one latch engaging the stop e' on the frame and the shoulder g of the other latch engaging the shoulders c of the plates d ct of the frame. Thus by operating the bar e3 both latches will be released, as above explained, and the carrierframe will be permitted to move either way on the rail or track D. A vertically-movable yoke g2 loosely embraces the frame A and is provided at its free upper ends with lips g3. The yoke is guided by loops g", secured to the plates a a of the frame, and lugs g5, projecting from the said plates a a. Vith the yoke g2 thus arranged, when the sling-pulley frames are drawn up close to the carrier and said pulley-frames or casings made to engage or bear against the yoke g2 said yoke will be elevated and the ears or lips g3 made to engage the prongs g of one of the latches E', and thus free the carrier-frame and permit it to travel on the rail D in one direction.

The sling-pulleys F are mounted on frames F of pear shape, each having a hook F2 for the reception of the sling-ropes-` The frames F are also provided with an arm or projection h for the attachment thereto of the hoisting-rope h', said rope also passing over the pulleys C C within the frame A. In proximity to each pulley C isa clevis G, each clevis having two outwardly projecting arms t, which embrace said pulleys, and which are pivotally connected at their free outer ends to the plates a a of the frame A. The body of each clevis G rests normally in nearly a vertical position in close proximity tothe pulleys C, and are concave on their inner faces for the reception of brake-shoes t", which latter are maintained normally in contact with the hoisting-rope h by the gravity of the clevis.

The advantage ot' the brake-clevises straddling the pulleys D, as above explained, is that the circle of the brake follows the contour of the pulley, whereas if the brake-shoe were presented to the rope in the reverse position it would engage a smaller amount of the rope and thus be less effective in its operation.

rlhe elevises G are each provided at opposite sides with projections or lugsj, with which the prongs 7s of two levers H ll engage. The levers Il l'l are pivotally mounted between the plates d a of the frame A, and each provided at one side of its fulerum with prongs 7c to engage the lugs j, as above explained. The lever H is provided on the other side of its fulerum from the prongs 7c with a fiange 71:', having a curved upper edge, and at the lower end of this liange is a mouth or recess k2. The upper arm of the lever Il is made with an opening k3 for the accommodation of the flange k of the lever H, and the crossbar 7a4 at the inner end of this opening is adapted to enter and have a free movement in the mouth or recess k2 in the upper arm of the lever H. The upper end of the lever ll is also made to produce a nose h5. Now it will be seen that if the upper end of eith'er lever H or H be pressed toward the other said levers will be swung or vibrated on their fulcrums, and the prongs 7c, engaging the lugs j on the clevises, will raise said clevises, and with them the brake-shoes carried by them, and thus release the hoisting-rope h and release the sling carrying the hay. It may be here stated that the lugs or projections y' of one clevis may be located somewhat higher than the lugs j of the other, so that one brakeshoe will be released slightly in advance of the other.

Then the Acarrier having a load of hay connected therewith in traveling over the rail comes in contact with the tripping or locking IOO IIO

mechanism carried by the rail, the arm or projection E2 of plate E will be engaged by the flange 7c of lever H or the nose las of lever H (accordingly as to the direction which the carrier is traveling) and cause said levers to be vibrated on their fulcrums and thus release the brake-shoes from the ropes passing over the pulleys C C, as above explained. At the same time the carrier-will be locked by the engagement of the latches Ewith the shoulders cc on the frame A. In order to reverse the carrier it is simply necessary to pull on cord e, so as to lift bar c3 and free the latches E from the shoulders c and c. The carrier is then moved along the track to the other side of the stop E. The hoisting-rope h should then be disconnected from projection 77. of the pulley-frame F', the opposite end of the rope being attached to the projecting part h of the other pulley-frame. The carrier is then ready to move in the opposite direction.

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