BUCKET ELEVATOR.

SPECIFICATION forming part of Letters Patent No. 600,770, dated March 1 5, 1898.

Application iiled March 26, 1897.

To all whom t may concern:

Be it known that I, J AMES M. DODGE, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Bucket Elevators, of which the following is a specication.

The object of my invention is to so construct a bucket elevator1 that it can be charged intermittently with material from a dischargespout while its buckets are traveling in a horizontal run.

rThe figure in the accompanying drawing is a view illustrating a bucket elevator made in accordance with my invention.

A is an endless-chain elevator having buckets ci, which pass around a head-wheel B at the upper end and around two guidewheels O O at the lower end and around a wheel D at a short distance to one side of the guide-wheels O C', so that the elevator has a main vertical run and a short side run at the base.

In the present instance directly below the head-Wheel B is a guide-wheel E, around which the endless chain passes on its downward vertical run, so as to force the buckets back clear of the discharging material.

G is a discharge-spout from a suitable bin or feed-hopper. This spout has an extension l G', pivoted at g to the main spout, and carried by this pivoted section .are wheels g', which ride upon the cam edges a of the buckets a, so that the pivoted section G of the spout will raise and lower as the buckets pass under it, so that the iiow of material will be intermittent and each bucket will be charged uniformly. The wheels g', acting in conj unction with the cam edges a of the buckets, constitute an uninterrupted contact between the pivoted chute andthe buckets, whereby the raising and lowering of said chute to supply or cut off material are effected with the minimum amount of shock or jar.

I may provide means for adjusting the wheels g in respect to the several parts. One

age.

Serial No. 629,412. (No model.)

form of apparatus used is a lever g2, pivoted at g3 and carrying at its outer end a shaft upon which the wheels g are mounted. The other arm of the lever g2 is in the form of a segmental gear and meshes with the worm h on an adjusting-shaft H, so that the lever can be turned on its pivot. This mechanism is fully illustrated and claimed in an application filed by me of even date herewith. Other forms of adjusting mechanism may be used without departing from the main feature of my invention. It will be seen that by this method I am enabled to feed the buckets of the elevator while traveling in a horizontal plane and can feed them uniformly and considerably reduce the wear of the parts, as the buckets do not dig into the material to receive their load. Furthermore, I can by this arrangement elevate material which would be injured by the buckets digging into the body of material, as by feeding through the conveyer-chute in the manner described the material is handled with less liability of break- Other means of discharging the buckets at the head of the elevator may be used without departing from my invention.

I claim as my invention- The combination, in a bucket elevator, of an endless carrier, buckets thereon, said elevator having a main vertical run and short horizontal runs at the base, with a pivoted feed-chute situated above the upper horizontal run of the elevator, there being uninterrupted contact between the said pivoted chute and the buckets, for causing the buckets to raise and lower the chute as they pass under the same, substantially as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JAMES M. DODGE.
