JERSEY, A .CORPOR.A.TION 0F BUCKET ATTACHMENT FOR CONVEYERS.

Specification of Letters Patent.

Patented Oct. 11, 1910.

Application filed March 4, 1910. Serial No. 547,370.

To all whom it may concern:

Be it known that I, FRANK B. BALL, a citizen of the United States, residing at No. 259 Sherman street, Passaic, New Jersey, have invented certain new and useful Improvements in Bucket Attachments for Conveyers, of which the following is a clear, full, and exact description.

This invention relates to conveyers, and the main object of the same is to provide an endless belt conveyer with a shield, or protecting medium, at a point under the bucket, whereby the belt is protected from abrasion or injury, due to the action of the bucket, when particles of coal, stone or other mate; rial accumulate between the bucket and the belt, and still other objects are to render conveyers of the described type more efficient and durable.

These being among the objects of the invention, the same consists of certain features of construction to be hereinafter described and then particularly pointed out in the claims, with reference to the accompanying drawings, showing a desirable form of the invention and in which- Figure 1 is a side elevation of a portion of a conveyer provided with my improvement. Fig. 2 is an enlarged front elevation of a portion of my improved belt conveyer, looking toward one bucket, and Fig. 3 is a side view of the same parts.

Referring to the drawings, the belt 1 may be of any suitable construction and conducted over a pulley 2 in a wellknown manner. There is a pulley for the other end of the ordinarily endless belt.

It is found in practice with endless con veyer belts, provided with buckets, that particles of coal, stone or other material find access into the spaces between the buckets and the belt, with the ultimate result that abrasion and injury to the belt takes place due to the grinding action produced by the said particles, which action is greater in the region of the pulleys. It is my aim to overcome this objection, to which end there is located upon the belt, underneath the buckets 8, protecting spaced shields 4, preferably of thin sheet metal or other suitable flexible material, adapted to protect the belt against injury, should particles of stone, coal or other like particles find access to the spaces between the buckets and the belt. Each shield 4 is of a greater area than the area of the back of each bucket and s secured to the belt preferably by means of rivets 5, and, as the said shield is preferably flat, said rivets hold it flat upon the belt so that throughout its under-surface it contacts with the belt. The rivets pass through all the edges of the said shield 4. A plurality of said shields are secured to the belt, so that there is one shield for each bucket, the intervals between the shields corresponding with the intervals between the buckets. The buckets are secured to the belt in any desired manner, such as by means of extensions 6 of the backs of the buckets, so that one end only of the bucket is attached, while the other end of each bucket is free to permit said bucket being carried around a pulley.

Under the free end of each bucket there is secured to the said shield 4 a transverse bar 7, which constitutes a strike-member or abutment for said free end of the bucket. Said shields 4 also obviously reinforce the belt l underneath the buckets and prevent stretching or distortion of the belt at the points under the buckets. They also furnish reliable supporting means for the buckets.

What I claim as new is:

l. In a conveyer, the combination of abelt, a bucket attached thereto at its upper end only, and a flexible shield secured to said belt between said bucket and said belt.

2. In a conveyer, the combination of a belt, a bucket attached thereto at its upper end only, and a flexible shield secured at its edges to said belt and located under said bucket.

3. In a conveyer, the combination of a belt, a bucket attached thereto at its upper end only, and a flexible shield secured to said belt between said bucket and said belt, and being of a greater area than that of the back of said bucket.

4. In a conveyer, the combination of a belt,
