ELEVATOR AND DUMP.

SPECIFICATION forming part of Letters Patent No. 532,022, dated January 8, 1895. Application filed August 23, 1894. Serial No. 521,056. (No model.)

To all whom it may concern:

Be it known that I, RUSH BULLIs, of Milton, in the county of Rock and State of Wisconsin, have invented a new and useful Improvement in Elevators and Dumps, of which the following is a description, reference being had to the accompanying drawings, .which are a part of this specification.

My invention has relation to improvements in elevators and dumps, having particular reference to devices for elevating and dump- 1ng gram.

The main objects sought to be attained are simplicity in construction and rapidity of action, and in connection therewith strength and durability.

The invention also contemplates the provision of simple means for dumping the load automatically, the construction being such that the dumping can be efiected at varying heights.

With the above objects, and others, in view, the invention consists of the devices and parts, or their equivalents, as hereinafter more fully set forth and claimed.

In theaccompanying drawings, Figure 1 is a longitudinal vertical sectional view of the complete device. Fig. 2 is a front elevation of the upper portion thereof. Fig. 3 is a view of the rear side of the car; and Fig. 4. is a cross section taken in front of the car.

Like numerals of reference denote like parts throughout the several views.

Referring to the drawings, the numerals 5-5 indicate the side beams of a scaffold, connected at their upper ends by a transverse beam 6. The side beams form the outer rails or ways of my improved device, and'are connected at regular intervals by cross strips 7. Intermediate the outer rails 55, and secured centrally to the cross strips 7 is a single fiat track 8, which extends partially the longitudinal length of the scaffold. This central track is preferably composed of a series of sections, as shown clearly on the drawings, se-

cured end to end in any desirable manner, and

thereby permitting the track to be readily shortened or lengthened.

The numeral9 indicates a car or receptacle, having its rearside inclined, as clearly shown. To this rear side are secured, at opposite edges, angle brackets 10 40, the depending flanges of which are adapted to fitagainst the v inner sides of the outer tracks or rails 55. At the lower end of the inclined rear side is provided an exit opening 11, and bordering the side edges of this opening are angular strips l212. At the rear of the depending flanges of these angular strips is j ournaled a transverse shaft 13, upon which is hung a gravity opening door 14.

In suitable recesses 1515 at the lower end of the car are mounted rollers 1616, said rollers, in the travel of the car along the trackway, diminishing the friction materially at the points where the greatest friction would necessarily occur. At the upper end small blocks 17 -17 are secured, so as to dispose the car on a perfectly level plane.

Secured to the inner side of the rear piece of the car, near the upper edge thereof, is a doubly grooved pulley l8, and'rnounted in the upper transverse beam 6 is a similarly grooved pulley 19. attached at its upper end to one of the cross strips 7. This cord is then extended downward and around one of the grooves of the pulley 18, thence upwardly and around one of the grooves of the pulley 19, thence down again and around the other groove of the pulley l8, thence up and around the other groove of pulley 19, and finally extended laterally and downwardly and around a singly grooved pulley 21 mounted in one of the side tracks 5. The free end of the cord or rope is preferably passed around another pulley (not shown) at the base, the cord being in convenient posi tion for manipulation by the operator.

The numeral 22 indicates a hopper for catching the grain as it is discharged from the car. This hopperis provided atone end with hooks 2323, which are adapted to engage the crossstrip 7 where the central track 8 terminates.

Pivoted to the center of the opposite edge of the hopper is a long hook 2%, the freeend of which is adapted to engage a pin 25 projecting from the next cross-strip above.

In use, my improved device may be arranged inoperative position either within a granary or outside thereof. In either case, the scaffold is, preferably, of sufficient length to admit of the upper end thereof extending'up to the top of the store room, and to rest against, or be supported by, the beam or rafter 26, as

An operating cord or rope 20 is shown in Fig. 1. \Vhen the car is properly adjusted to the trackway, it will be seen that the rear side thereof rests upon the top edges of the side tracks or ways 55, while the depending flanges of the angle brackets 10 rest against the sides of the tracks or ways. This latter prevents sidewise displacement of the car. The door 14 bears against the central track 8, and is normally held closed thereby. Afterthe car is filled with grain, and it is desired to elevate the same to an upper story of the granary, a pull is given to the operating cord or rope, and this causes the rapid ascent of the car up the inclined way. As soon as the car reaches the end of the central track 8, however, all support for the door 14 is removed, and of course said door immediately drops by gravity, and the grain is emptied through the exit opening 11. If the hopper 22 is used, the grain, of course, is emptied directly therein, and may be conveyed therefrom to any part of the room by means of a suitable piping coupled to the hopper. I do not wish, however, in any sense, to be understood as limiting myself to the use of my invention in connection with this hopper, as it .is obvious that, if preferred, the grain can be emptied directly onto the floor, or may be dumped directly into a suitable pipe, and conveyed thereby to any portion of the room. As soon as the car is emptied of its load, the cord or rope is allowed to slip through the hands of the operator, and the car, of course, will descend the incline by gravity, the door let immediately closing automatically as soon as the car begins to descend, by reason of the contact of said door with the end of the central track 8.

If it is desired to dump the load at greater height than that shown in the drawings, of course all that is necessary to be done is to attach another length of the central track 8, while if it is desired to dump at a less height, a length of said track is removed.

As the depending flanges of the angular strips 12 fit against opposite edges of the door, it is evident that if the contact of the door with the central track does not have the effect of fully closing said door, said depending flanges will prevent any leakage of the grain during the travel of the car.

that I provide a most simple and rapidly working device, of such construction that the 1 load may be elevated with a minimum amount 3 of power and in which the dumping is effected with the slightest possible loss of time.

While I have described my device as having particular reference to means for elevating and dumping grain, yet it is apparent that the same may be conveniently used as an elevator for freight, and in fact all kinds of goods and commodities.

Having thus described my'invention, what I claim, and desire to secure by Letters Patent of the United States, is
