LOADING AND DUIVIPING DEVICE.

To all whom it may concern:

Be it known that I, TILDEN J.'BYLER, a citizen of the United States, residing at Blanco, in the county of Blanco and State of Texas, have invented a new and useful Loading and Dumping Device; 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.

This invention relates to the art of excavating and hoisting, and road grading mechanism, and 'it more particularly pertains to a new and useful device for loading gravel and similar materials upon wagons.

The main object of the invention is to utilize the same in connection with the ordinary scrapers and teams, that is, the device or loading apparatus is to be situated at the place where the gravel or similar material is to be obtained, after which the gravel or other material is scraped upon the tray, by the ordinary Scrapers being driven over the tray, thus loading the same. The tray is then hoisted to the desired height, and subsequently the wagon, which hauls the gravel to the road bed or any other location, is driven under the tray, after which the hinged two-part bottom is released, thus allowing'- the gravel or other material to be dumped into the wagon. After the two part bottom of the tray is released the same is again closed and the tray lowered, and the operations above set forth again repeated.

The device, as herein described and shown in the drawings, may not only be used for loading gravel and the like, but may be employed in excavating, or upon farms, whereby fertilizer and other material may be loaded in wagons. In the drawings, however, there is only disclosed one particular form of the invention, but in practical fields this form may require alterations, to which the applicant is entitled, provided the alterations are comprehended by the appended claims.

The invention comprises further features and combinations of parts hereinafter set forth, shown in the drawings and claimed.

In the drawin su-Figure 1 is a side elevation of the hoisting and loading apparatus, constructed in compliance with the invention, showing the hoisting and loading Specification of Letters Patent.

tray in its lowermost position. Fig. 2 is a view similar to Fig. 1, showing the loading tray in its uppermost position, and illustrating a wagon in dotted lines beneath the tray, whereby the contents of the tray may be dropped into the wagon. Fig. 3 is a View in end elevation, further disclosing the features of the invention. Fig. 4 is a top plan view of the apparatus. Fig. 5 is a View in side elevation of one side of the hoisting tray. Fig. 6 is a section view on line 6-6 of Fig. 5.

Referring' to the annexed drawings, 1 designates a rectangular frame work, which converges slightly toward the upper portion and is suitably braced by the transverse and angularly arranged braces 2 and 3. The braces are secured firmly in position by means of the various bolts fl. The corner beams of the frame work may be provided at their lower ends with rollers, wheels or the like 5, whereby the frame may be movable from place to place. However, only two of the corner beams may be provided with wheels, while the other two beams may be connected in any suitable manner to the rear of a wagon, thus making it possible to move the apparatus from one place to another.

Extending transversely of the upper portion of the frame is a shaft 7 upon which drums 8, 9 and 10 are mounted so as to rotate with the shaft, there being two outside drums and one intermediate drum. Connected to and partly wound around the drums 8 and 10 are the cables 11, which pass over the pulleys 12, which are secured to the upper transverse braces of the frame work. The lower ends of the cables 11 are connected to the side flanges 13 of the tray 14, as illustrated in the drawings. Connected to and considerably wound about the drum 9 is the cable 15, by which the shaft at the top of the frame work may be rotated. It will be observed that the said cables are arranged in such wise, as to permit the tray 14 to be hoisted, by imparting a pulling action upon the cable 15, which will unwind the cable 15 from the drum 9, and in turn will wind the cables 11 upon the drums 8 and 10. The said shaft at one end is provided with a ratchet wheel 16. Pivoted to sioned pawl 17, which is designed to coperate with the ratchet, in order to prevent the cables 11 from unwinding from the drums 8 and 10. In other words the pawl prevents retrogression of the said shaft. Connected to one end of the pawl 17 is a pull co-rd 18, which passes over a pulley 19 carried by the frame. The other end of the cord 18 is connected to a lever 20, which is pivoted at the base of the frame work. This lever 20 is provided with the usual dog 21 to engage the usual form of quadrant 22, whereby the lever 20 may be held in adjusted positions. The lever 20 is also provided with a hand grip for manipulating the dog 21. JAlso connected to the lever 20 is the pull cord 23, the upper end of which, after having passed over the pulley 2% is connected to a brake lever 25, which is provided with the usual brake shoe 26. When it is desired to allow the tray 14 to lower, the lever 20 is oscillated downwardly, thus releasing the spring tensioned pawl from engagement with the said ratchet, which will permit retrograde movement of the said shaft, thus allowing the cables 11 to unwind and the cable 15 to wind. At the same time the shaft is permitted to have a retrograde movement, the brake shoe of the brake lever is applied against the side of the drum 9, by virtue of the pull cord connection between the brake lever and the lever 20.

The hoisting tray comprises a rectangular met-al frame having two side flanges 13, and provided with a two part hinged bottom. To hold the two

parts

27 and 28 of the hinged bottom in closed positions cables 29 are provided, which at one of their ends are connected to one of the side flanges 13, while their other ends are wound about and positively connected to a revoluble rod shaft 30, which is mounted in suitable bearings' 31 of the other flange 13 of the tray. Carried by and rotatable with the rod shaft 30 at one end thereof' is a beveled gear 32, which meshes with a beveled gear 33. The beveled gear 33 is carried by and rotatable with a vertical shaft 34, which is arranged at right angles to the shaft 30 and is provided with a crank handle 35. The shaft 34 is mounted in bearings 36, as shown in the side elevation of the hoisting tray. A ratchet wheel 37 is mounted upon the shaft 30 so as to rotate therewith. Engageable with the ratchet 37 is a spring tensioned pawl 38, and connected to the pawl is a pull cord 39. By imparting a pulling action on the pull cord 39 the pawl 38 will be released from engagement with the ratchet, and by the Virt-ue of the weight of the contents on the two hinged parts of the tray, the cables 29 will be permitted to unwind from the shaft 30, thus allowing the hinged

parts

27 and 28 to open. When the hinged parts open, the contents of the tray will be allowed to dump into the wagon.

After the contents are dumped the v may be again lowered in the manner hereinbefore stated, for another loading of gravel or other material.

From the foregoing it will be observed that a novel form of apparatus for hoisting gravel, or other material for loading the same into wagons has been devised, and one which is found to be practical in every phase of its operations, and also one which is found to fulfil all the requirements in practical fields.

The invention having been set forth, what is claimed as new and useful is 1. In combination with a hoisting mechanism, a loading tray including two hinged parts, transverse cables attached to one side of the tray at one of their ends, a rotating member mounted in bearings at the other side of the tray about which the cables are wound, and means for releasing the rotating member, a crank shaft arranged at right angles to the rotating member and including beveled gear connections with the member whereby the same may be rotated for rewinding the cables thereon, thus closing the two hinged parts.

2. In combination with a hoisting mechanism, a loading tray including two hinged parts, transverse cables attached to one side of the tray at one of their ends, for holding the parts in closed positions, a rotating member mounted in bearings at the other side of the tray about which the cables are wound, a ratchet movable with the rotating member, a pawl in engagement therewith for preventing rotation of the member, a pull cord for releasing the pawl from engagement with the ratchet, thus permitting the two parts to open, a crank shaft arranged at right angles to the rotating member and including beveled gear connections with the member whereby the same may be rotated for rewinding the cables thereon, thus closing the two hinged parts.
