This invention relates in general to a conveyor and is more particularly described as a portable conveyor for receiving coal or other material and discharging it at a distance therefrom. In unloading coal or other material from a wagon or truck, it is frequently desirable to discharge material at a different elevation either above or below the point where it was received. For power conveyors, an electric motor or an internal combustion engine may be provided, but a source of current is not always available, and for a more general use or application, a small internal combustion engine is desirable. If such an engine is placed upon a conveyor which is tilted at various inclinations, the oiling and fuel systems are seriously affected if not 'rendered inoperative. The present invention provides an adjustable mounting fora conveyor of this type in which provision is made for maintaining the engine in upright position for various inclinations in either direction froma horizontal position.

An important object or the invention is in the provision of a conveyor adapted to be positioned at various inclinations and having an adjustable motor support and mounting which may be varied in accordance with the inclination of the conveyor to maintain an upright position and thus to provide for an efiicient operationof the engine. c

A further objector the invention is to provide a portable conveyor of a type adapted to be carried with a truck and transported from place to place for use therewith, the conveyor having a wheel upon which it is mounted and a removable engine and mounting which may be quickly applied to and removed from the conveyor.

A still further object of the invention is to provide a belt type conveyor having a gear reduction drive from an operating engine or pulley and a conveyorbelt which may be tightened and loosened depending upon the material or service desired.

:A still further objectof the invention is to provide a light and strong portable conveyor 11 Claims. (01. 198-203) Bil adapted toreceive material at one end and to deliver it from the other end with an intermediate driving means mounted above the conveyor and movable at various angles with respect thereto. i

Other objects of, the invention will appear in the specification and will be apparent from the accompanying drawing in which,

Fig. 1 isa side elevation of a conveyor in accordance with this invention.

Fig. 2 is a sectional view of the conveyor shown end or side of a truck where material may be shoveled or dumped directly upon the receiving end of the conveyor, the other end of the 'conveyor is elevated or inclined to deliver the material at a higher or lower level and the operating engine is set up in its holder and fastened'at such an angle that it will be held therein in substantially upright position regardless of the inclination of the conveyor.

, Referring now more particularly to the drawing s', a conveyor frame is preferably composed of light-weight angle and channel bars 6 and I to form an elongated hollow structure of the desired length. The frame is substantially rectangular in cross section and comprises a metal trough or plate 8 extending along the top and having upright sides 9 with upwardly inclined ledges I0 and downwardly turned edges II which overlap the upper edges of theside frames. This trough 8 extends to a position adjacent the-rear end of the conveyor and is continuous to the front or discharge end of the conveyor.

At the rear end of the conveyor is a loading section l2 which is flush at the top with the remainder of the conveyor but preferably has continuous side plates and a bottom 13 which is inclined upwardly toward the end so that by disposing wheels I! upon an axle l5 which is mounted in brackets l6 extending downwardly from the main frame of the conveyor at a point just beyond the loading section, the rear end may approach the ground upon which the wheels are supported, thereby allowing the other or dis-v chargeend to be elevated to a greater extent.

Movable upon the plate or trough B is a continuous belt I! which passes over a roller or pulley l8 mounted upon brackets l9 extending forwardly from the end of the frame and also mounted at the rear end upon an adjustable pulley or roller 20 which has a mounting shaft 2| engaged at each end by a screw 22 which passes through a fixed perforated ear 23 projecting outwardly at the side of the frame and having adjusting nuts 24 for moving the pulley, thereby tightening the belt and holding the pulley in any adjusted position. The side plates Connected to the front pulley is a gear 28 118W.-

ing a sprocket chain 29 connecting it to a small sprocket 30 carried on a counter-shaft 3 l-mounted' weight for holding the pulley in belt distending position.

Also mounted near the rear end of the conveyor in side plates i secured to the upright sides 5 of the trough is an idler pulley 58 for engaging the belt IT. and guiding it to the rear roller 20.

'With Lthis,. construction,sthe conyeyoriisireadily set up for-use; the motor"and its'mounting may be quickly removed and quickly applied to the driving belt 5E3 which is tightened to driving relaconveyor by simply disengaging or engaging the tion and held in that position by the belt tightener pulley 53,": andthemotor mounting, which is easily in brackets 32 attached to the outer upright side's;
