SPECIFICATION forming part of Letters Patent No. 740,609, dated October 6, 1903, Application filed December 6. 1902. Serial No. 134,164. (No model.)

.To d/ZZ whom it may concern:

Be it known that I, GEORGE DANIEL WALKER, a citizen of' thel United States, residing at Orchard, in the county of.Morgan and State of Colorado, have invented a new and useful Combined Elevator and Dump, of which the following is a speciiication.

The invention relates to certain improvements in mechanism for elevating material of any desired character and automatically larger scale.

dumping the same at a required point.

lVhile the invention is'applicable for load. ing and unloading purposes in general, it is particularly intended, for use in loading rail' waycars and the likewith beets or other material at points along a railway-line where the amount ofmaterial handled is not suicient car has' been mo to warrant the expense of elevators and other loading appliances.

The principal object of the invention is to provide an elevator and dumping 'apparatus in which a oar loaded with any desired material is traveled up an inclined plane and on reaching the top of the plane automaticallydumps its contents.

A further Object of the invention is to provide an improved form of dumpingcar in which at the dumping-point the forward sec-A tion of the car ,is automatically moved to dumping position without necessitating'the travel of the main car-body beyond the upper portion of the inclined plane.

A still further object of the invention is to provide a car-supportin g frame capable of. adjustment with relation to a line of railwaytrackto permit its ready removalwhen in use, and thus avoid danger of'damage to passing trains.

A still further object of theinvention is to provide for the automatic adjustment of a portion of the car-supporting frame when theV ved therefrom and approaches the opposite limit of movement.

Vith these and 'other objects in view the invention consists in the novel construction and arrangement of parts hereinafter desoribed,illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that various changes in the form, proportions,size,and

Y minor details of the structure may be made without departing from the spirit or sacrifieing any of the advantages of .the invention.

In the accompanying drawings, Figure 1 is a side elevation of an elevator Vand dump constructed in accordance with the invention, the car being shown .in full lines in dumping position and in dotted lines in the loading position at the bottom of the inclined plane. Fig. 2 is a sectional elevation of the car and a portion of the supporting-frame Ona somewhat- Fig. 3 is `a front elevation of the frame. Fig. 4. is a rearrelevation of the car. Fig. 5 is a view similar to Fig. l, illustrating a slight modiiioation of the invention. Fig. 6 is a detail sectional view,on an enlarged scale, illustrating the arrangement of the forward end of the track when the same is to be adjusted to inoperative position by hand.

Similar numerals of reference are employed to indicate corresponding parts throughout the several figures of the drawings.

When the device is'to bee'mployed for load ing railway-cars, the front portion of the supporting-frame of the inclined plane is disposed about siX feet, more or less, from the 'railway-track, said frame comprising-a lower ,sill l0 and two pairs of upright-s 11 and l2,

connected by an upper horizontally-disposed beam 13. The frame maybe further strength- 'enedjbytruss-braces lll of any ordinary character.v 'beams or rails l5, extending rearwardly from Ytlietop of the front frame to the ground and preferably supported at an intermedi ate point The inclined plane comprises a pair of byV an auxiliary upright frame 16.

' The structure thus far described may be formed of wood or metal and made permanent in character by the employment of suitable foundations, and if necessary a power plant may be installed in the form of a small Y explosive-engine or the like, although for ordi-v fnary purposes a team of animals will generally be found sufficient.k

To'the front of the main frame are hinged a pair of rail members 1S in alinement with the rail'members 15 of the inclinedplane and adapted to receive the forward wheels of the car when the latter reaches the top of the plane. The outer ends of the rail members 1S are hinged or pivoted to an gularly-disposed strips or bnraces 19, the lower ends of which are pivuprights when the apparatus is in use.

1, the struts will be pulled upwardly and will.

force the auxiliary rail members 1S inward and over the top of the main structure, so as to be out of the way of passing trains. On the upward movement of the car as it approaches the top of the inclined plane the tension on the cord or chain will be relaxed and the struts and auxiliary rail members will fall to the position shown in Fig. 2 by gravity. In order to properly guide the rail members in moving to and from their-two positions, each of said members is provided with an auxiliary bar 21, extending through a, pivotally-mounted guide 2l, carried bya bracket extending from the main portion of the frame, the pivoted guides serving as a means for preventing` lateral displacement of the rail-sections during the movement.

The car is formed of two members hinged or pivoted together in such manner that they may separate at the top of the inclined plane to permit the dumping of the contents of the car without necessitating the travel of the rear or main section of the car beyond the end of the inclined plane. The rear section of the car comprises a strongly-braced frame 22, provided with supporting-wheels 23, which may travel on the track 15, and the iioor 24 of this section of the car is arranged at an angle to the angle ol' the plane, so as to permit the ready discharge of the contents of the car. The front section of the car has a pair of sillmembers 26, pivotally connected to the corresponding` members of the rear portion of the car and provided with a pair of supporting-wheels 27. The iioor of the front section of the car is parallel with the inclined plane, so that when the car is in loading position at the bottom of the plane an inclined pocket is formed for the reception of the material to be elevated and dumped. The sides of the car-sections are formed of planks 30, those of the front section slightly overlapping the corresponding planks of the rear section, so as to preserve the continuity of the sides of the car when the latter reaches the dumping position.

The hoisting mechanism in the present instance comprises two sets of blocks and tackle, one block of each set being connected to the horizontal cross-bar 13 of the main frame and the other being connected to the under side of the car at a point near the rear end thereof. The ends of the tackles pass through suitable guiding-sheaves carried by the sill 1 0, and are thence conducted to a small engine or hitched to a team of horses or the like in order to haul the car to the top of the inclined plane.

In the operation of the apparatus the car, being at the bottom of the inclined plane, is loaded with the material to be elevated and the car is hoisted to the top of the plane. The front section 25 of the car first passes from the rails 15 of the inclined plane onto the rails 1S beyond the frame, and the contents of the car are moved bv gravity toward the front end thereof to fall into a suitable receptacle, as a railway-ear or vessel, the angular position of the bottom portion 24 of the rear section of the car insuring the discharge of the material from the rear section. In some cases, depending on the class of material being handled, it may be desirable to travel the rear section of the car for the greater dis4 tance or until its Jforward wheels are resting on the track members 18, thus increasing the angle of the floor of the car and insuring the discharge of its contents. Excessive movement of the car is prevented by extending one of its rear frame members 32 laterally from each side'of the car to form stops for engagement with the upper ends of the uprights 12, this being clearly illustrated in Fig. 1.

In order to provide for the return of the car from the track members 18 to the inclined plane, I preferably employ a weight 35, secured to a rope 36, having one end connected to the rear end of the car, the Weight being sufficient to return the empty car to the inclined plane and the latter thence traveling by gravity to loading position at the bottom of the plane.

The arrangement of the auxiliary rails and their supporting-struts may be modified in the manner shown in Figs. 5 and 6, wherein similar numerals of reference designate parts corresponding to those already described.

To the front of the main frame are hinged the inner ends of a pair of rail members 18', in alinement with the rail members 15 of the inclined plane and adapted to receive the forward wheels of the car when the latter reaches the top of the plane. The outer ends of the rail members 18 are hinged to angularly-disposed struts or braces 19', the lower ends of which rest on blocks 20 when the apparatus is in use. When not in use, the braces 19 are removed from engagement with the blocks 20 and the braces and rail members 19 then fall into a vertical line in parallel relation withthe front frame, as shown by dotted lines in Fig. 5, thus preventing danger of contact with passing trains.

It will be understood that the apparatus may be employed in connection with the loading of cars or vessels of any character and that any'suit able power may be'employed for operating the device without departing from the invention.

I-Iaving thus described the invention, what is claimed is- 1. The combination with an inclined track, of an auxiliary track-section extending from the highest point thereof and inclined in a IIO loA

ldirection opposite thereto, a car having a plumaintained in an approximately horizontal position, and both sections being adjusted to dumping position when 'moved onto the auxiliary tracks.
