LOADING DEVICE.

Specification of Letters Patent.

Patented April 2'7, 1909.

Application filed. June 4, 1908. Serial No. 436,703.

To all whom it may concern:

Be it known that 1, WILLIAM F. LENHARD, a citizen of the United States, residing at Darwin, in the county of Meeker, State of.

Minnesota, have invented certain new and useful Improvements in Loading Devices;

and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

The present invention has reference to loading devices, and it aims, generally, to provide an exceedingly simple, durable and eiiicient device of that nature designed especially for loading manure.

To this end, the invention briefly described, comprises a portable derrick provided with an inclined runway, whose upper end is extended rearwardly, and a fork arranged to travel upon the runway and adapted to be tilted when it reaches the extended end thereof, to dump its contents into a wagon or upon the ground at a particular spot, as the case maybe.

The invention resides more especially however, in the particular construction of the derrick and the runway carried thereby and in the attachment to the derrick frame of a pair of levers arranged for swinging movement in parallel vertical planes, so as to move the ground wheels with which they are provided into and out of engagement with the ground, said wheels occupying the former position when the loading device is.

in operation, and the latter position during its movement from place to place.

The invention further resides in the particular construction of the fork, in the provision of rollers for facilitating the downward movement of the fork upon the runway, and in the particular devices employed for effecting the movement of the fork.

The preferred embodiment of the invention is illustrated in the accompanying drawings, in which corresponding parts are desig natcd by the same reference numerals throughout the,several views, wherein:

Figure 1 is a perspective view of the loader, showing the fork in position at the foot of the runway. Fig. 2 is a vertical section, showing the fork at the top of the runway in the position which it assumes at the completion of its tilting movement. Flg.

3 is a side elevation of the loader in position" for transportation. Fig. 4 is a rear elevation of Fig. 2. Fig. 5 is an enlarged plan view of the fork. Fig. 6 is a transverse vertical section therethrough. Fig. 7 is a front elevation of the fork. Fig. 8 is a detail view of a scraper adapted for use in connection with the fork. Fig. 9 is a detail view of the wheel-carrying levers. Fig. 10 is a plan view of the supplemental brace illustrated in Fig. 1.

Referring more particularly to the drawings, 1, 1, designate the converging vertical beams of the derrick frame whose upper and lower ends are connected together by the cross-beams 2 and 3, the beam 3 having its opposite ends resting upon and secured to the side beams 4: of the derrick frame, to which beams the beams 1 are likewise attached at their lower ends. The rear ends of the beams 4: project beyond the beams 1 and are rounded or beveled upwardly at such polnts, to form runners 5, while their front ends are fastened to the side beams 6 of-the. upwardly-inclined runway 7, whose jupper end is secured to the beams 1 intermediate their ends, extending therebetween, as shown in Figs. 2 and 3, to form a platform 8', said runway tapering gradually in width from its lower to its upper end. The

runway is strengthened by a series of parallel horizontal-braces 9 which are secured to its under face, while the lower portion of its outer face has fastened thereto, a metal wear plate-l0, as shown in Fig. '1, the lower .arms of the frame, said arms being further provided at their ends with alining openings through which the shaft 12 passes.

Owing to their attachment to the shaft 12, the levers 11 are capable of a swinging movement in parallel vertical planes, carrying with them the ground wheels, as will be apparent. When, therefore, said levers are swung upwardly toward the runway, the

wheels will be raised from the ground, while the lower edge of the runway will be brought into contact therewith, and when the levers are moved in the opposite direction, or toward the cross-beam 3, the wheels will be brought into contact with the ground and the runway edge raised thereabove. To retain the levers in either position, the beam 3 and one of the braces 9 are provided respectively with swinging catches 16 and 1. which are movableinto and out of engagement with the levers.

The fork which is adapted to travel upon the runway and is operated by a cable 18, as hereinafter described, comprises a handle 19 and a series of tines 20 whose upturned rear ends are bolted to a cross-piece 21 to which the lower end of the handle is rigidly secured. In the present instance, seven tines are shown, the two outer tines and the central tine projecting some distance beyond the cross-piece 21 and having their curved eX- tremities secured to the top member of an open rectangular frame 22, whose lower member is disposed beneath the several tines, which latter are riveted thereto. During its downward movement upon the runway, the rear end of the fork is supported upon a pair of rollers 23 rotatably mounted upon the free ends of the legs 24: of an inverted U-shaped frame 25, formed of strap iron. Intermediate their ends, the legs 2% are provided with perforations 26 in which are pivotally engaged the hooked ends of a wire bail 27 provided intermediate its ends with an eye 28, the lower portions of said legs being bent so as to extend outwardly of the tines and below the same, as shown.

The operating cable 18 above referred to, is secured at one end to the cross-beam 2, is led downwardly and passed around a pulley 29 whose block is connected with the eye 28,. and is finally led upwardly and passed over a pulley 30 carried by a block suspended from said cross-beam, the free end of the cable being then led downwardly to permit its attachment to a whiflie-tree, (not shown).

In the operation of the device the wheel carrying levers 11 are raised and engaged with the upper catches 17 after which the manure is collected upon the fork in the usual manner and the draft animals hitched to the Whittle-tree. As the animals move away from the derrick, the fork will be caused to travel upwardly along the runway, the tines of the fork being held in approximately horizontal position by means of the rollers 23, which latter are secured to the legs of the frame 25 located toward the rear ends of the tines. As the fork reaches the platform 8, the fork is tilted, as shown in Fig. 2, under the tension of the operating cable, the rear ends of the tines being raised and their front ends lowered, thus dumping the manure upon the ground at the particular spot selected. or into a wagon, as the case .y be, it being understood that the wagon when used. is backed up sutliciently close to the derrick frame to permit the fork to discharge its contents thereinto. \Vhcn a sufficient quantity has been col lected either upon the ground or in the wagon, the fork is raised into the position shown in Fig. 8, and its operating cable wound around an upwardly bent U- shaped frame 31 secured to one of the braces S) at the rack of the runways, the fork being thus retained in its raised position. The levers 11 are then lowered and engaged with the catches 16 on the cross-beam 3,bringing the ground wheels 15 into operative position in contact with the ground and raising the lower edge of the runway above the ground, as shown in the last mentioned figure. 'lhe derrick is then moved to another spot, the draft chains (not shown) being connected to the lower ends of the beams l. or to the side beams 1-. As the manner of etleeting the bodily movement of the derrick, however, forms no part of the present inventien, illustration thereof is accordingly omitted. During the tune that the device is actually in operation, it is held against: movement by a guy rope 32 which is fastened to the ends of the cross-beam 2, this rope being wound around the beams 1 when the derrick is moved from one place to am other. The derrick frame is preferably provided with a pair of wire cables 32 which are fastened at their upper ends to h top beam 2 and at their lower ends to he front ends of the side beams 11-, the cables ending to strengthen the derrick frame. as will be apparent.

It is to be understood that the machine may be used with equal facility in loading the manure into a. wagon instead of at a particular spot upon the ground, as the wagon may be backed up sutlieiently close to the derrick frame to enable the fork to dump its contents thereinto.

Where it is desired to load dirt, gravel, or the like. which is tine enough to pass be: tween the lines of the fork, the latter may be provided with a shield 34;, which is fitted over the tines and is held in place by straps secured thereto, the side edges of the shield having openings, in which hooks secured to thearms of the brace 16 are engaged. The forwz rd edge is provided with a steel scraper.

During the time that the apparatus is actually in operation, it may be further supported and held against displacement by the supplemental brace illustrated in Fig. 1, said brace comprising a beam 35 whose upper end is connected with the upper ends of the beams 1, 1, by means of a V-shaped frame 30, the sides of which receive the lit) .lllt) beam 35 between their rear ends, the connection between the latter beam and the frame being edected by a bolt 37 arranged for interchangeable engagement in one of a series of openings 38 formed through said beam What is claimed is:
