CONVEYER-BUOKET.

Specification of Letters Patent.

Patented Feb. 15, 11116.

Application filed February 20. 1915. Serial No. 9,737.

To all vwhom. it may concern.'

Be it known that I, Cmiunvon E. (limitar, a citizen of the United States, residing at St. Paul, Decatur county, and State of Indiana, have invented and discovered certiiiii new and useful Improvements in Couveyer-Buckets, of which the followingr is a specification.

My invention relates to buckets for elevating coiiveyers and its object is to provide effective means for reventing material such as stone or rocks alling from the bucket upon the belt and crowding between suoli bucket and the surface of the belt or beneath the bucket and particularly to thus protect the belt and bucket when the latter is passing over the pulley of the conveyor.

With this object in view, my invention is embodied in preferable form in the construction hereinafter described and illustrated in the accompanying drawings.

In these drawings. Figure 1 is a side view in elevation of an elevating conveyor showinf;` buckets embodying mv invention applied thereto; Fig. 2, an enlarged plan view of ono of the buckets; Fig. an enlarged vertical section.

Referring to the drawings, 1 designates a conveyor belt which is ada ted to be so mounted as to carry material roin one point to a more elevated point and which is driven b v and passes around an uper pulley 2 and a lower pulley 3. Secure on this bolt by rivets or other suitable moans of connection are conveyor buckets -t havin their lower or bottom ends, viewed in the ine of flight ot the conveyor, provided with a retaining lian e and being open at their upper or forwar( ends for the purpose of permitting the material to be discharged as the bucket reaches the upper pulley und descends on the downward stretch of the belt.

Adapted to be secured to this bucket by rivets or other suitable means of fastenin is a plate bearin against the bottom o the bucket. This p ate is secured on the upper face of the bottom of the bucket and pro'ects forwardly beyond the edge of the uc (et (proper a short distance and at the forwar pro'ecting edge is rovided with ears 7 turne over so as to orm alternate receiving sockets for the pintle of a hinge.

An apron 8 is hin ,ed to this late and extends forwardly a ong the be t. The rear edge of this apron is provided with ears 9 similar to the ears 7 and through the ears of the belt and apron respectively is adapted to be passed a piiitle 10. By means of this hinge connection the apron is loosely connected to the forward ortion of the bucket. The apron is exten ed beyond the sides of the bucket at each end thereof for the purpose of preventin the apron from falling within the body o the bucket as the latter is moved upwardly.

The width of the apron is such in relation to the distance between two adjacent buckets that as the apron falls downwardly toward the belt as the buckets are passing over the pulley, the forward edge of the apron will strike against the rear wall of the preceding bucket and rest against the same at an angle, thus effectually preventing stones or other material carried by the bucket from falling therefrom dowii u on the belt or becomin lodged between the belt and precedin ucket or between the apron and said ucket, or between the belt and the bucket carryin the apron.

If desired, t e hinge members such as 5 may be formed directly upon the forward edge of the bottom of the bucket and the apron thus hinged directly to the bucket body, but the use of the attached plate carrying the hinge renders the device capable of application to buckets already in use.

Having` thus described my invention, what I claim is:

1. A conveyor havinar a belt and a series of conveyor buckets, in combination with an apron between each two adjacent buckets` said apron being hinged to the forward bucket and extending above the bottom line of the buckets at an anglo to the belt and over the space between said buckets so as to lie against the wall of the preceding bucket above the bottom thereof whenever the buckets aro traveling at such an angle as to cause the apron to swing forwardly.

2. A conveyer bucket closed at one end and open at the forward end in the line of travel for the purpose of permitting` the discharge of material, in combination with a plate attached to said bucket, an apron extending forwardly from Suid bucket und this seventeenth dny of I*`eb1'nnry, A. D. adapted to occupy the spuce between the two nineteen hundred und fifteen.
