'0 ME whom, it rnrty concern:

Be it known that I, DANIEL OTTO, acitizen f the United States, residing at Bloomingon, in the county of McLean and State of ,llinois, have invented'certain new and useful improvements in Portable Derricks, of which he following is a specification, referencebehg had therein to the accompanying drawings. i This invention relates to an improvement n portable derricks for grain-elevators, and sdesigned more particularly for use in coniection with that type of grain-elevators hich is in itself portable and designed to reeive grain from a wagon and elevate the ame toa bin or.otherdepository. The present invention contemplates a strucure which is so fashioned that in the act of iransporting the elevator the derrick as such lnay'in' part serve as a vehicle onto which the elevator is deposited for transportation and also a construction whereby with facility the lerrick can be raised properly positioned and hereafter the elevator drawn up to theproper nclination. .uch a character that its structural arrangenents and connections are such as to render t light, strong, and convenient for handling ind transporting.

In the accompanying drawings, Figure 1 llustrates the invention in elevation. Fig. 2 s a rear view. Fig. 3 is a view similar to Tig. 1, showing the parts lowered; and Fig. i is a similar view showing the-parts in posi- .ion for transportation.

A in the drawings designates a base mem- )6! or shaft, carrying on its outer end suit' tble truck-wheels B. Secured to this shaft A are two uprights CC. converging toward their upper ends and there firmly united, a pmall cross-bar being interposed between the extreme ends. These uprights may be traced by suitable parallel upright braces D 1), springing from the shaft A and connected @ixedly to the sides of the uprights G G at points intermediate the ends of the latter.

E E designate diagonals connected to the upright braces D' D midway and extending forward, their extreme lower Iends being formed with curved portions, as at E and )rovided with seats or supporting-blocks E The runner or curved edges of the diagonals E E are positioned on a plane with the wheels B. Extending from the diagonals E E rearwardly "ire thebraces, F F, their forward ends being Incidentally, the invention is of rcinovably connected to the lower ends of the upright braces D D, thus forming in the combination a truss structure rendering the derrick rigid and maintaining it in its elevated position. These bars or braces are conveniently formed with a series of apertures f, through which the connecting-pinf' may be passed, connecting the same removably with the axle or shaft A through the bases of the upright braces D D. By this means -the derrick-proper can be varied as to its inclina tion.

G designates the elevator,having the pivoted drag H thereon of any approved or well-known type. supporting-blocks E of the diagonals E E in any convenient manner, conveniently by the operating-shaft S, as shown. In this connection suitable boxes are to be employed, although it is manifest that any suitable means for supporting the elevator on the lower end of the diagonals may be used. The upper end of the elevator carries a bail J, to which a suitable hoisting-rope K is attached, the same passing over pulley-blocks supported by the short cross-bar at the upper end of the derrick. The supporting-rope in turn is carried down into operative position.

In operation the elevator when adjusted for use is in the position shown in Fig. 1, the lower portion resting on the diagonals and the upper portion being carried by the derrick proper. can by proper manipulation of the rope be adjusted to any convenient angle or lowered to the position shown in Fig. 3 for transportation. When the elevator is lowered. the drag is turned back onto the same, the braces F F are uncoupledfrom the upright braces D D, and the wheeled axle is thereupon turned or moved backward, the pivotal point between the diagonals and the braces serving as the center around which the axle may turn. This act lowers the uprightderrick-members, carrying the lower ends toward the rear and the upper ends down on the outer end of the elevator, as shown in Fig. 4. In this position by applying the draft power to either end of the derrick the same can be readily transported from place to place.

From the above-described construction, it

The elevator is supported on the In this position the elevator.

will be observed that the portable derrick comprises, essentially, two frames, one consisting of the upright braces and the other of is claimed as new, and desired to be secured by Letters Patent, is

1. In a portable derrick for portable elevators, the combination with a derrick having suitable wheels at its lower end, of forwardlyextending members pivotally connected with the derrick, and a brace located below the forwardly-extending members and removably connecting the derrick and the forwardly-extending members.

2. In a portable derrick for grain-elevators, the combination with a shaft, of. derrickuprights secured thereto, diagonal members extending therefrom, their lower ends being fashioned to receive the lower end of the elevator, detachable braces between the diagonalsand the uprights, and an-elevator, substantially as described. I

In a portable derrick for portable elevators, the combination of a wheel-shaft, of a m BEST AVAILABLE cor ing from the derrick, a detachable brace interposed between the derrick member and the diagonal members, an elevator, and means connected with the derrick for raising and lowering the elevator,

4. In a portable derrick for portable elevators, the combination with a wheel-shaft, of inclined derrick members carried thereby, parallel braces between the inclined members, diagonal supporting members extending from the parallel braces forward, and removable brace members between the diagonal members and the shaft.

5. A portable derrick for portable eleva tors comprising a derrick member and forwardly-extending supporting members, a

shaftto which the said members are con nected respectively, a brace member detach ably connecting the said other two members, and an-elevator carried by the derrick.

6. In a portable derrick for portable elevators, two frames arranged at an angle to each other and pivotally associated so that the same can be folded, and a detachable brace member between the frames and adjustably connected to one of the frames. l

In testimony whereof Iaflix my signature in presence of two witnesses.
