SAMUEL P. LERICI-I, OF CANTON, OI-IIO.

HAY-CARRIER.

Specification of Letters Patent.

Patented Nov.A 2, 1909.

Application led December 21, 1908. Serial No. 468,438.

To all whom it may concern:

Be it known that I, SAMUEL P. Lenoir, a citizen of the United States, and a resident of Canton, county of Stark, and State of Ohio, have invented a new and useful Improvement in Hay-Carriers, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

In the construction of hay-carriers or hayelevators, as the devices are variously known, it has been found desirable to provide means for sustaining the load at any desired elevation below the carriage by which it is transported, for example, from the wagon to the mow, in the case of the particular commodity in question. Ordinarily it will be understood, such carriers require to have the block or lifting-pulley to which the load is attached, raised into engagement with a hook in the carriage, thus necessitating in many instances considerable useless labor, as where the mow is only partially filled, the load being elevated the entire distance merely to be dropped an A equal distance when the desired point for its deposition is reached. One form of construction for thus sustaining the looped portion of the hoisting cable, and the block attached thereto at any desired elevation is shown in my Patent No. 797,131, dated August l5, 1905.

The object of the present invention is'to provide means for securing` a similar result, but which, by operating on a dierent principle, will obviate a number of the difficulties inherent Ain the earlier construction.

To this and related ends, said invention then consists of the means hereinafter fully described, and particularly pointed out in the claims.

The annexed drawing and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but one of various mechanical forms in which the principle of the invention maybe used.

In said annexed drawing r-Figure l is a side elevation, with parts broken away and shown in section, of 'a hay-carrier embodysing my several improvements; Fig. 2 is a similar view of a portion of such carrier with parts shown 1n a different operative position; and Figs. 3 and 4 are end elevational views of the gripping mechanism proper that I utilize to sustain the cable in the manner above described, such mechanism being shown closed in the first instance and open in the second.

Only brief attention need be paid to the 'general features of construction of the car-- rier or elevator, comprising as it does, the familiar carriage A that is adapted to travel upon a suitable track B, inthe present instance of T-cross section, made of two anglebars placed side by side with their flanges disposed outwardly. The body A of the carriage is swiveled with respect to the portion A2 that runs on the track, and is characterized by having a bell-like portion a, by

means of which the hoisting block or liftingpulley C, when raised, is guided into engagement with a hook a 'pivotally mounted in such carriage portion. This block O is carried by the looped portion c of the hoisting cable O, one end of which is secured to the lcarriage at a2, the other end of which passes over a pulley a3, and thence to the power, (usually a horse) hitched to such cable end. dog at pivotally mounted adjacent to the upper end of the hook, is adapted to lock the same in its operative position in which it engages the block, but is automatically raised from this position upon encountering a stop o provided for this purpose on the under side of the track B over the loading station. This stop in the present improved construction, however, is movable so as to permit of its being raised, as will be presently explained. A second fixed stop b upon the under side of the track a short distance from the movable block, prevents movement of the carriage in the opposite direction, when dog at is raised (Fig. 2), but permits such move- `ment of the carriage when the dog is dropped into its locking position (Fig. l)

The means provided for gripping the cable to sustain the looped portion thereof at any desired elevation, are designed to be entirely independent of the pulley a3 in their operation, comprising two members a5 pivotally mounted in the carriage frame (Figs. 3 and It), the free ends of such members extending upwardly adjacent to said pulley, and on opposite side of the cable, so as to grip the latter upon being moved inwardly.

Such inward movement of the gripping members a5 is effected, upon the hook a beilk ing raised to its operative position, by meai'is of suitable connections, comprising in their preferred form, tvvo transversely disposed levers a, the outer re-curved ends of Which are connected With said members respectively, While the inner ends overlap and are slotted to receive the round end al of another lever as longitudinally disposed with respect to the carriage, 'and connected by means of links a9 With the hook aforesaid. A. lever L10 mounted upon one end of the short shaft all on which said hook is fixed, is utilized to thus operate the same, and, therethrough the gripping members When 'desired; and, as Will be obvious, this operation will take place automatically Whenever the hoisting block C is raised into engagement with the hook a in the usual fashion. Another lever b having one end connected with the movable stop on the track by means of a link 3, similarly serves to raise such stop when desired.

Having thus described the construction of my improved carrier, its mode of operation should be readily apparent. The load, attached to the hoisting block C in any approved fashion, may be raised to any desired height, short of a position in which such block actually engages the hook in the carriage, and then by pulling on a rope connected with actuating lever al, the gripping mechanism will be operated to close upon the cable, and securely sustain the looped portion thereof, so that the load can be transported at such intermediate position along the track. This is the condition of the earrier as illustrated in Fig. l. This movement of the carriage is thus at the same time rendered possible, for by the same movement of the hook, the dog a* locking the same drops beloiv the plane Where it would engage the fixed step b on the track. Should it be desired on the contrary, to move the carriage in the opposite direction, it is simply necessary to raise the movable dog b into the position indicated in dotted outline in Fig. l, and

thus leave the Way clear for such movement also. On the return of the carriage, however, such movable stop being in its normal position, is adapted to raise the dog at, thus permitting the hook to drop into 4its inoperative position, and simultaneously release the cable from the gripping members a5 so that the hoisting block may be lowered for another load. The condition of the carrier parts, When such carrier is held relatively stationary between the dogs b and b', is clearly shown in Fig. 2. In this condition it ivill be understood the members a5 do not grip the cable, but allow the latter to run freely over pulley a3 as is necessary in elevating the load. If it is desired to raise the load to the full height, it Will be obvious that the carrier operates exactly as though no gripping device were provided in connection therewith. Such operation, aside from being self evident, is too familiar, to require description here.

Other modes of applying the principle of my invention may be employed instead of the one explainechchange being made as regards the mechanism herein disclosed, provided the means stated by any of the following claims or the equivalent of such stated means be employed.
