CONVEYER.

Specification of Letters Patent,

Application filed January 18, 1911.

Patented June 25, 1912.

Serial No. 603,319.

To all whom it may concern:

Be it known that we, ARTHUR C. STARK- WEATHER and JOHN NAGEL, citizens of the United States, residing at Amherst, in the county of Lorain and State of Ohio, have invented. certain new and useful Improvements in Conveyers, of which the following is a specification.

This invention relates to new and useful improvements in conveyers and more particularly to the class adapted for use in excavating purposes, but it is not to be limited to such use alone and can be put to any application which the arrangement of its various parts might present.

An object of this invention is to provide a conveyer comprising a car which is adapted to run upon an elevated track -mounted upon the upper ends of braced supporting posts, the said car and supporting posts being provided with suitable means whereby the car can be operated by a person or persons standing adjacent one end of the track.

A further object of this invention is the production of a device of'the class described, comprising but few parts which are so simple in construction that they can be manufactured at a minimum cost.

With the above and other objects in view, this invention consists in certain novel formations, combinations and arrangement of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawing, in which:

Figure 1 is a side elevation of a conveyer constructed in accordance with our invention. Fig. 2 is a section on the line 22 of Fig. 1. Fig. 3 is a section on the line 33 ofFig. 1.

Referring to the drawing by characters of reference the numerals 1 and 2 designate a pair of supporting posts connected at their upper ends by an overhead track or cable 3 and braced by suitably arranged guy wires 1. The post 1 is stationed a convenient distance from the point of excavation A and is slightly higher than the post 2 in order that the track 3 will be inclined outwardly, allowing the car 5 when loaded to be impelled by gravity to the dumping point B. The car 5 is composed of upper and lower side rails 6, the opposite ends of which are connected by upwardly diverging parallel end bars 7. The upper side rails 6 are connected by means of transverse shafts 8 upon which are rotatably mounted peripherally grooved wheels 9 which are adapted to ride along the track or cable 3.

The medial portions of the end rails 7 are connected by shafts 10 provided with grooved pulleys 11 over which passes a driving or propelling cable 12, one end of which extends over a pulley 13 mounted upon the post 1 and thence .downward to a drum 14 around which it is wound several times and then back over a pulley 15 mounted upon the said post 1 to the forward end of the car 5 to which it is secured. The opposite end of this cable 12 runs over a pair of idlers 16 mounted upon the post- 2 and back to the rear end or tail of the car to which it is then attached.

Suspended below the car 5 for vertical adjustment is a bucket supporting frame 17 provided upon its lower end with a hook 18 for the engagement of the bail or handle of a bucket 19.

In order to provide for the vertical adjustment of the bucket supporting frame 17 a drum 20 is journaled in the frame which supports the drum 14 is mounted and has secured to it a cable 21 which passes over a pair of pulleys 22 carried by the post 1 to a pulley 23 carried by the lower forward end of the car 5 and runs down and around a grooved wheel 24 journaled in the frame 17, upward over a pulley 25 carried by the car, back over the wheel 24 and again upward to the car 5 and over a pulley 26 mounted thereon, to the post 2 to which the end is suitably secured.

From the foregoing it is manifest that upon the rotation of the drum 14; the car will be propelled along the cable 3 through the medium of the cable 12 while the cable 21 will pass over the pulleys and allow the bucket to remain at the same height from the ground at all times. Obviously however, upon the rotation of the drum 20 the cable 21 may be either lengthened or shortened and thus raise or lower the bucket to any desired height above the ground.

Having thus fully described this invention what is claimed as new is:

The combination in a conveyor, of a pair of uprights an inclined cable connecting said uprights, a wheeled frame movable upon said cable, a drum, pulleys supported upon the uprights, a cable attached to the drum and extending over said pulleys and attached to the wheeled frame, a bucket supby its weight and the weight of the bucket porting frame, a second drum, pulleys supporting frame.

journaled in the said wheeled frame, pulleys In testimony whereof we affix our signajournaled in the bucketsupporting frame, a tures in presence of two witnesses.

scable attached to the second drum and passing over the pulleys journaled upon the ARTHUR STARKWEiATHER' wheeled frame and engaging the bucket JOHN NAGEL supporting frame, means for rotating the Witnesses:

drums, the said wheeled frame adapted to L. B. HATZBAUER, 10 be propelled to the lower end of the cable ALBERT DUANE.
