LOADING MACHINE,

Application filed March 17,1926. Serial 'No.: 95,351.

This. invention relates to a loading machine.

The object of the invention is the construction of a comparatively simpleand efficient 11130111118 for rece1vmgaload, and conveying tions, combinations and arrangements of parts as will be hereinafter fully described, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims.

In the drawings g t Figure 1 is. a longitudinal; central, sectional view of my loading machine, showing the; same in a working or unfolded condition.

Figure 2 is a view in side elevation of my loading machine, showing the same in a Figure 3 is a top plan view of my loading machine.

Figure 4 isa sectional view taken on line 44', Figure 1, and looking in the direction of the arrows.

Figure '5 is a plan view of the frame of the auxiliary conveyor device. a

Figure 6 is a transverse sectional view of the primary conveyor device.

Figure 7 is a fragmentary perspective view of the bridge device.

Referring to the drawings by numerals, '1 designates the primary conveyor device; 2 is the auxiliary conveyor device, and 3 is the hoisting device, of my loading machine.

The primary frame 4 of the loading machineis supported at its forward end upon wheels'5, and the rear ends of frame 4 are provided with downwardly extending curved legs 6. lintern'iediate the legs 6 and the front end of the frame, I securely fasten an inverted iii-shaped axle 7 upon the lower ends of which are journalled large wheels 8. Between the legs 6 and axle 7 is a pair of uprights 9 that constitute part of the hoisting device 3. r

The primary conveyor device 1 comprlses a frame 10, which is provided at its. ends with shafts 11, uponwhich are secured the gear wheels 12. Mounted ,on these gear wheels are-sprocket chains 13 and suitably. carried by these chains 13 is aslatted belt 14. Extending through the. frame is a rod 15; this rod is near'the inner end of the frame, and its ends are'slidably mounted in -the vertically extending elongated slots 16 which are formed in the curved leg 6. A rod 17 extends through the frame 10 near its outer end, and mounted upon this rod 17 is a U- shaped support 18; this support 18 is comparatively broad and rests uponthe ground whenthe apparatus is inoperation,.Fig. 1. The auxiliary conveyor device comprises frame 19 that has shafts 20 at its ends and fastened .to these shafts 20 are gear wheels 21 upon, which are mounted the sprocket chains 22. =A slattedbelt 14 is mounted upon these chains 22 "The frame 19'is'suitably fastened within frame 4 to retain it in its ,desiredjinclined position, as shown.

The driving shaft 23 is suitably journalled upon frame 4, and any source of power, such as an ordinary gas engine, may be connected up to this shaft'23 for driving the conveyors. Fastened-to shaft 23 is a gear 24' and fastened to shaft 11, of the primary conveyor device 1,-is a gear 24. Mounted upon gears 24 and 24 is sprocket chain 24", which chain serves todrive the chains 13 and belt 14 of the primary conveyor device, whenfthe ma chineis in operation.

Fastened to shaft 20 is gear 25 and mounted upon gear 26 is sprocket chain 27. whereby when power is imparted to shaft 23 the auxiliary conveyor device will beoperated.

The bridge device 28 comprises a platform section 29 having in its center'a large opening 30. This platform 29 is supported upon legs 31. These legs 31 straddle the primary conveyor device, and support the platform slightly above the same, with the opening 21 in position to permit material of, any kind to drop on the conveyor belt 14 as the ma terial is dumped upon the platform section 29. Runway pieces 32 are fastened by hooks 33 to the side edges of the 'platform'section 29, with theirf outer ends resting upon the ground so that a scoop of material or a cart or a wagon load of sand gravel or any other material can be easily drawn upon the platform section 29 and thrown or dumped through the opening 30 onto the conveyor belt 14, from which belt the load is dumped platform section 29 and then lift the plat form section with its legs 31 from entirely off the primary conveyor device. Then i operate the hoisting device 3 to raise the primary conveyor device to its folded or I raised position as shown in Figure 2.

The hoisting device 3 includes the uprights S), as hereinbefore stated, and journalled upon the upper ends of the uprights 9 is a shaft 35 which is provided at one end with a c ank handle 36, Figure l. Wound around this shaft 35, constituting a drum, is a cable 36, which cable 36 is connected to cable 37, which cable 3'? has its ends fastened to rod 17. Cables 38 are wound at their upper ends (Fig. 4) around drum shaft 35 and their lower ends are fastened to the inner rod 15, so that when shaft 35 is retated to wind cables 36 and 38 thereon, the outer end of the primary conveyor device will be swung to its raised folded position, and at the same time its inner end will be somewhat raised, by red 15 travelling to the upper ends of slots 16 to place the con- Veyor clear of the ground and in a compact folded position, as shown in Figure 2. The pivotally mounted support 18 also swings so as to place its ground engaging or base portion snug againt the primary conveyor device. A suitable pawl and ratchetdevice 39 is placed upon shaft 30 and one of the uprights 9, to hold the shaft 35 against rotation when supporting the load of the primary conveyor device when in its folded position, Figure 2.

When it is desired to operate the machine, the hoisting device is operated. to lower the primary conveyor device to its horizontal position, Figure .1, andlhen the cables 36 and 37 are removed; the Lridge device is placed in position and then the machine is ready for operation.

lVhile I have described the preferred embodiment of my invention and illust'ated the same in the accompanying drawings, certain minor changes or alterations may appear to one skilled in the art to which this invention relates during the extensive manufacture of the same, and I, therefore, reserve the right to make such changes oralterations asshall fairly fall within the scope of the appended claims. lVhat I claim is:

1. In a loading machine, the combination of a frame provided at its inner end with slots of the legs, means connected to said rod for raising and lowering said primary conveyor device upon said frame, and an auxiliary conveyor devlce on the frame and adapted to receive material or a load discharged from the primary conveyor device. 2. In a loading machine, the combination of a frame provided with legs at one end, uprights formed upon said frame near the ends of said legs, a drum shaft journalled upon said uprights, a primary conveyor device between said legs and adjustably mounted upon said legs, and means wound upon said drum shaft and connected to the primary conveyor device near its ends for bodily lifting the conveyor device and also for swinging its outer end to an elevated or folded position, and an auxiliary conveyor device on the frame and adapted to receive a load from the primary conveyor device.

3. In a loading machine, the combination of a frame provided at one end with legs, a pair of uprights attached to the frame near said legs, a drum shaft mounted upon said uprights, a conveyor device including a frame positioned between said legs, rods extending through said frame near its ends, said rod near the inner end of the frame having its ends slidably mounted upon said legs, a cable having its ends fastened to the red at the outer end of the frame, a second cable having onev end wound around said drum shaft and having its other end fastened to said first mentioned cable, a pair cables having their upper ends wound around said drum shaft'and their lower ends fastened to the rod near the inner end of said frame, whereby when said drum shaft is operated to wind the cables thereon, bodily and swinging movement will be imparted to said conveyor device, and means carried by the frame for conveying a load received from said conveyor device. In testimony whereof I hereunto aflin my signature.
