CONVEYER.

SPECIFICATION forming part of Letters Patent N o. 597,376, dated January 11, 1898. Application filed February l1, 1897. Serial No. 622,991. (No model.)

To @ZZ whom t may concern:

Be it known that I, GEORGE B. Kuno, of Goodfarm township, in the county of Grundy and State of Illinois, have invented certain new and useful Improvements in Conveyers; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference markedthereon, which form part of this specification.

This invention relates to certain new and useful improvements in conveyers, and more particularly to that class known as portable and adjustable elevators.

The invention consists in certain novel features of construction and in combinations of parts more fully described hereinafter and particularly pointed out in the claims.

The object of the invention is to provide a conveyer simple, cheap, and durable of construction and composed of a minimum number of parts.

A further object of the invention is to provide a conveyer that can be easily and quickly transported and adjusted as desired to suit any machine, such as corn-shellers, threshers, and cars or wagons and the like, described elsewhere. i

Another object of the invention is to provide means for adjusting the conveyer to the desired height or angle by means of the slotted lever and legs, which are adapted to slide and work on a pivot, and also to control the conveyer and to throw it into and out of engagement with the driving-gear by means of the spring and clutch.

In the drawings, Figure l is a side elevation of my invention. Fig. 2 is a top plan view thereof; and Fig. 3 is a central longitudinal section on the line 3 3, Fig. 2.

Referring by letter to the accompanying drawings, co is the frame or trough of the conveyer closed atone end and provided with the hopper or flaring side pieces b.

c are the pivoted and adjustable legs or supports, p the levers, and r the rods connecting the legs c and levers 19.

In the discharge or open end of the frame or trough a, a suitable distance below the top of the sides, is a shaft d, carrying the two sprocket-wheels e and the clutch f, operated by the lever g. The drive-gear h also has a clutch-jaw h to register with and engage the clutch f. The cog or sprocket wheel 7L is loosely mounted on the shaft d and normally held in engagement with the clutch f by means of the spiral spring '11, which encircles the shaft d, and held in place by the split pin j in the end of said shaft d. 7c is an endless belt carried by the sprocket-chains k' and having the cross-bars or take-ups Z at suitable intervals throughout its length.

Beneath the sprocket-chainsk', about midway, I arrange two or more beveled guides fm, adapted to take up slack, prevent sagging, and the chains from falling below the sides of the trough or frame.

The haring side pieces t are removable, so that when the conveyer is to be inserted in a filled crib or bin the closed end can be thrust into the materialsuch as grain, ears of corn,

or any stuff-to be carried. The plate n, at the closed end of the body or trough, in clines down close to the endless belt, covers and forms a housing for the sprocket-Wheels o in that end of the frame, and also guides the corn or the like into the conveyer.

When it is desired that the flaring pieces be attached, the corn may be shoveled into the con veyer and thence to the desired point.

In operation the conveyer is inserted into a crib in such a position that the corn or the like will by means ofthe inclined guide-plate n be directed to the belt and thence to the discharge end of the conveyer,\rhich has been placed to deliver the corn to the machine or desired receptacle, the conveyer being set in motion by its driving connection to any suitable motor. housed and protected by and beneath the said inclined plate n and the legs folded against the sides of the conveyer to avoid obstruction and so that the frame of the conveyer may lie horizontally or in a flat position.

It is possible that the corn or the like may be conveyed too rapidly, and in such oase the lever g is pushed, forcing the drive-wheel h against the tension of the spring il and the clutch-jaw h' out of engagement with the clutch f, thus allowing the endless belt to rest, While the Sheller or other machine may operate The rear sprocket-wheels are' without interference. Then Whenit is desired to let more corn pass the lever is released and the spring takes effect, forcing the drive- Wheel to engage the clutch and the conveyer to continue its Work.

The uses and advantages of this device are many. It is light and can be easily moved. It is simple of construction and not easily disabled, accurate, direct, and quick of action.

It is evident thatvarious slight i changes might be made in the forms, construction, and arrangements of the parts described Without departing from the spirit and scope of my invention. Hence I do not wish to limit myself to the exact construction herein set forth.

Having thus fully described my invention, what I claim, and Wish to secure by Letters Patent of the United States, is-

l. The combination with a conveyer frame or body of the pivoted and slotted levers, the pivoted and slotted legs, and the connectingrods, said parts arranged in such manner that the slotted portions of said legs and levers slide over their pivots, whereby, the frame may be raised, lowered or held in horizontal position.

-2. A portable conveyer comprising the trough or frame, adapted to carry the movable inclined side pieces forming a hopper, the inclined end guide-piece, sprocket Wheels and chains, covered by said inclined end piece, the endless conveying-belt adapted to be carried by said sprocket-Wheels, the sprocket-Wheels for operating said conveying-belt, adjustable legs adapted to be folded up against the sides of the frame When the conveyer is to be inserted into a body of grain and guides on the inside of said frame to prevent the conveyingbelt from sagging, as set forth.

In testimony that I claim the foregoing as my own I affix my signature in presence of two Witnesses.

GEORGE B. KRUG.
