Application filed December 4, 1920. Serial No. 428,298.

To all whom it may concern:

Be it known that I, JOHANN C. SELL, a citizen of the United States, residing at Pryor, in the county of Mayesand State of Oklahoma, have invented certain newv and useful Improvements in Loading Mechanisms, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improvegeneral character especially designed and adapted for use in connection with'shocks, and it is an object of the invention to provide a device of this general character em-, bodying a sweep supported for vertical swinging movement, together with novel and improved means for imparting upward movement to the sweep.

, Another object of the invention is to provide a deviceof this general character of a portable type including a sweep, together with means whereby the load received by the sweep may be readily and conveniently delivered to a collecting or receiving member such as a trailing barge.

An additional object of the invention is to provide a novel and improved device of this general character including a sweep supported for'swinging movement in a vertical direction, together with power driven means for imparting upward movement to the sweep and wherein means are employed to assure the downward movement of the sweep after discharging its load. Furthermore, it is an object of the invention to provide a device of this general character embodying a vertically movable sweep, together with novel and improved means whereby the downward movement of the sweep may be readily regulated "inaccordance with the requirements of practice.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my im proved loading mechanism whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth. [*1

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the tatably supported by;

better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein:

Figure 1 is a view partly in side elevation and partly in section illustrating a loading mechanism constructed in accordance with an embodiment of my invention, a second position of the sweep being indicated by. dotted lines.

Figure 2 is a view partly in section and partly in top plan of the structure as disclosed in Figure 1.

Figure 3 is a view in rear elevation of-certain of the parts comprised in my device as herein set forth, and v Figure 21 is a fragmentary view illustrating in detail the brak'ing mechanism herein employed. I As disclosed in the accompanying drawings, T denotes a portable body and preferably a tractor and which includes a casing 1 for the shafts of the rear or drive wheels D. Engaged with the opposite end portions of the casing 1 are the rear end portions of the elongated arms 2 having swinging movement in a vertical direction. The arms 2 are arranged inwardly of the wheels D and eX- tend forwardly of the body ortractor T inwardly of the front or steering wheels F and terminate in advance of the body or tractor when said .arms 2 are substantially horizon- .tal or in their lowermost position.

Carried by the forward end portions of the arms 2 and in advance of the portable body or tractor T is a sweep S of a conventional type adapted to be employed in connection with shocks or the like.

Extending rearwardly from the opposite end portions of the casing 1 and inwardly of the arms 2 are the rearwardly directed beams 3 immovable with respect to the body or tractor T and which preferably terminate rearwardly of the wheels D. The rear end portions of the beams 3 support the uprights 4 disposed. on a slight forward incline. Connecting the upper portions of the uprights 4: and the forward portion of the body or tractor T are the brace members 5 whereby said uprights are maintained in a rigid position.

A transversely disposed shaft 6 is rothe rear end portions of the beams 3 and t e lower portions of the uprights 4 and said shaft at a point substantially midway between the uprights 4 1 the be is provided with an annular flange 7 so that the portion of the shaft 6 between the uprights 4 constitutes a pair of separated winding drums.

Fixed to one end portion of the shaft 6 is a relatively large pulley 8 around which is disposed a belt 9. The belt 9 extends forwardly of the body or tractor T and is also disposed around a pulley 10 in driven conconditions, the proper gripping action of the have requisite frictional or said members belt 9 upon said pulley 10.

The upper'stretch of the belt 9 also passes under an idle pulley 12 rotatably supported by the free end portion of an elongated arm or lever 14 having its opposite end portion loosely engaged with the shaft 6 so that said arm may be capable of vertical swinging movement.

The arm or lever 14 has rigidly connected therewith an upstanding and forwardly inclined lever 15. This lever 15 provides means whereby downward pressure may be imposed upon the arm 14 to cause the pulley 12 to tighten the belt 9 so that said belt will gripping engagement with the pulley 8 so that the shaft 6 may be rotated in one direction at the will of the operator:

.Rotatably supported by the upper end portions of each of the uprights 4 are the pulleysl6 over which pass the flexible mem bers 17. The forward end portions of the members 17 are secured to therear'portions of the sweep S adjacent the opposite ends thereof whi e the opposite end portions of are secured to the opposite end portions of the shaft 6 and are adapted to be wound therearound upon rotation of said shaft 6 through the instrumentality ofthe belt 9. This winding of the members 17 upon the shaft 6 results in an upward swinging movement of the sweep S so that the load thereon may be delivered 01' discharged rearwardly of the body or tractor T and preferably within a trailing barge or wagon fragmentarily indicated by B. The upper end portions of the uprights 4 are connected by a downwardly and rearwardly inclined apron 18 upon which the load from the sweep is initially received and which serves to assure the proper delivery of the load within the barge Just before the sweep S reaches the limit of its upward movement, the arms 2 come into contact with the transversely disposed rod or member 19. This member 19 is secured at its opposite end portions to the bolts 20 slidably disposed through the upper portions of the uprights 4 and movable in a direction ,longitudinally of the body or tractor'T. These bolts 20 extend in advance of the uprights 4 and terminate in the enlargements 21.

Interposed between the enlargements 21 and the forward edges of the uprights/4 are the expansible members 22 herein disclosed as coil springs encircling the forward end being suflicient to throw the arms 2 beyond a vertical center.

As the sweep S descends and the'fiexible members 17 unwind, the shaft 6 will be rotated in a direction reverse to its rotation by the belt 9. It is of importance to regu-' late or brake this second rotation. of the shaft 6-to control the downward movement of the sweep S. As herein disclosed, the shaft 6 has fixed thereto a disc of brake wheel 23v with which coacts a brake strap 24, said strap being operated in a Well known manner through the medium of the lever 25. By proper operation of the lever 25, the sweep S may be brought to a stop at any point during its downward movement or such movement may be at a speed preferred and particularly at such speed to cause the sweep S to reach its lowered position or come in contact with the ground without undue force or impact.

The lever 25 "s provided with a conventional type of latch mechanism 26 coacting with the rack27 so that the lever 25 may be locked in its desired position either to lock the sweep S in an elevated position to hold the strap 24 in such contact with the coacting disc or brake wheel to maintain the lowering movement of the sweep S at a predetermined rate of speed.

It is to be understood in practice that the body or tractor T is caused to travel forwardly with the sweep S in its lowered posivention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principlesand spirit thereof and for this reason I do not wishto-be understood as limiting myself to the precise arrangement ease-re I and formation of the several parts herein said arms being of shown in carrying out my invention in practice except as hereinafterclaimed.
