To all whom 'it may concern:

Be it known that I, ARTHUR MARVIN, a citizen of the United States, residing at El Paso, in the county of VVoodford and State of Illinois, have invented a new and useful Loading Apparatus; and I do hereby declare that the following is a full, clear, and exact description of the invention, which it appertains to make and use the same.

This invention relates to an improved loading apparatus which is supported upon a running-gear and which is specially constructed and devised for the loading, transportation, and unloading of conveyers such as are used in connection with corn-shellers, said conveyers being oftentimes of great len h and considerable weight, whereby by ordinary means are rendered diflicult.

The object of the invention is to provide an apparatus which shall be simple, inexpensive, and eflicient for the purposes set forth. v

With these and other ends in view, which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts, which will be hereinafter fully described, and particularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations, and modifications within the scope of the invention may be made when desired.

In the drawings, Figure 1 is a perspective view of an apparatus constructed in accordance with the principles of the invention. Fig. 2 is a side elevation of the same. Fig. 3 is a side elevation of one end of the device, illustrating a modification. Fig. 4 is a perspective detail view of the upper end of one of the masts and the bearing-sleeve connected therewith.

Corresponding parts in the several figures are indicated throughout by similar characters of reference.

The improved loading apparatus is sup-- ported upon a running-gear which includes front and rear axles 1 2, having carrying- 'wheels 3 3 and 4 4, said axles being connected with each other by means of crossed rods 5 5, enabling short turns to be made,

said rods serving to connect the axles in place of the ordinary reach. A tongue 6 has been shown connected with the front axle by I means including the hounds 7. will enable others skilled in the art to which Bolsters 8 9 are pivotally supported upon the axles 1 2 by means of vertical pins or bolts 10, which also serve to secure in posi- .tion the sill 11, which latter is thereby pivotally connected with the bolsters and the axles. Each of the bolsters supports,

near one end thereof, a mast 12, having a derrick-arm 13, which is reinforced by an obliquely-disposed brace 14. Each of the bolsters is provided with a pair of sockets 15, in which the lower end of the mast may he stepped for rotation, said sockets being located intermediate the sill, and the ends of the bolsters and the mast being capable of being readily shifted from one to the other of said sockets. The upper extremities of the mast have terminal pintles 16, for which bearing-sleeves 17 are provided, each of said bearing sleeves being provided with a plurality of perforated ears or lugs 18.

A stay-rope 19 is connected with one of the' lugs 18 of each of the bearing-sleeves. A guy-rope '20 extends from another lug 18 of each of the bearing-sleeves to points of attachment, as at 21, near the ends of the sill.

Still other lugs 18 of the sleeve 17 are connected by guy members 22 with stakes 23 at the ends of the bolsters. It will be noticed that the bolsters are provided with stakes 23 at each end thereof and that the guy members 22 are connected with the stakes opposite to those above which the derrickarms 13 are extended. The guy members 20 and 22 are preferably connected with the sill and with the stakes by means, including clevises 24:, which enable said guy members to be conveniently disconnected and attached, as may be required, this being essential in order to permit the masts to be readily shifted from the sockets at one side of the sill into the sockets at the opposite side.

The masts 12 have been shown as provided with brackets 25, sustaining windlasses ings include windingsdrums 26, mounted upon shafts 27, having worm-gears'28, meshing with worms 29 upon crank-shafts 30, whereby the drums may be readily rotated to wind or unwind the flexible members 31, which are suitably guided over pulleys 32 and 38 upon the derrick'arms and which at their extremities carry hooks 34, which may be readily made fast to the object that is to be lifted. It is to be understood, however, that windlasses of any well-known and approved construction may be used in con: nection with the improved apparatus within the scope of the invention.

\Vhile in the foregoing description stayropes and guy-ropes have been referred t0, it is to be understood that rods may be substituted, if desired,

AS illustrated in Fig, 3 of the drawings, the stay member 19 may be omitted and guy members, as 19, may be substituted, said guy members being connected directly with h s de o he sill.

In connection with the derrick device there is used a trestle 35, having an arm 36, pro.- vided with a terminal hook 3'1, whereby it may be connected with a staple, as 38, at either side of the sill. The object of this device will be presently set forth,

From the foregoing description, taken in enn ction with the draw ngs heret nnexed, the operation and advantages of this invention w1ll be readily understood. The

masts may be readily stepped in the socketsv 15 at the side of the sill distant from the O je t h t is to b lo ed, By manip la ing the windlasses the hooks 34 are lowered until they may be connected with the. object to be lif ede windla s s are t en 1 erated to lift the object until the latter may b pr g ve he Whee s a d e de s t d upon the runningl-gear, it bein pre erahly upp r ed P n t. s l 11- In. k mann r the derricks may be utilized to unload the object when desired.

s her ef st t d, th mpr d pparatus is designed especially for the handling and transportatlon of conveyers for n s llers, a d onveyers cons st ng of troughs which are sometimes made of great length and which are consequently unwieldy, heavy, and diflicult to handle. By using connecting-rods 5 and a sill 11 of suitable length the running-gear of this improved apparatus may be utilized for the transportation of conveyers of any length, conven-v ient means being provided whereby such conveyers may be loaded, unloaded, and otherwise advantageously manipulated;

In unloading a conveyer the trestle 35 is connected with the. sill in the manner described, and the arm 36 will thus serve to to be conveniently made or established without a preliminary heavy lift to bring the conveyer into the proper position. The trestle, as will be readily understood, may be quickly and conveniently connected with the side of the sill where the conveyer is to be unloaded. Having thus described the invention, what is claimed is 1. A running-gear including bolsters, a

sill pivotally supported upon said bolsters,

sockets upon the bolsters intermediate the sill and the ends of the bolsters, masts stepped for rotation in the sockets at one side of the sill and having derrick-arms, stay means connecting the masts, guy means connecting the masts with the ends of the sill and with the bolsters said guy means including clevises, windlasses supported upon th masts, and flexible hoisting members connected with the drums of the windlasses and guided over pulleys upon the derrick-arms.
