CONVEYER-CHAIN.

Specification of Letters Patent.

Eatented April 16, 1907.

Application filed September 15,1905. Serial No. 278,565.

' hereby declare 'the following to be a full,

clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention is an improvement in conveyer-chains, and relates more particularly to im rovements inconveyer-chains of the class i lustrated in Patent No. 743,070, issued to me November 3, 1903, which class of chains is especially adapted for conveying sawdust and other material of like nature.

The present improvement pertains particularly to devices used in connection with a conveyer-chain link of any suitable or usual form, whereby the link is made capable of acting effectually as a conveyer or scraper.

It has heretofore been common to attach laterally-extending wings to conveyer-chain links for this purpose; but these wings have been made with vertical front or working faces, and the win s have been extended at right angles to the ine of travel of the chain. In ractice it is found that the tendency of suc 1 a chain is to ride on top of the material to be conveyed, and it is not uncommon to see the material a foot or more deep under the chain.

The object of my present improvement is to obviate this difficulty and to rovide a scraper attachment that will not 0 y keep the corn veyer-trough clean but will, by reason of its form, tend to hold the conveyer-chain down to the bottom of the trough and to draw the material from the sides of the trough toward the center line of the chain instead of allowing the material to escape around the extreme ends of the conveyer-chain wings.

With these objects in view my invention consists in the devices illustrated in the ac-- companying drawings and the equivalents thereof.

Figure 1 is a top plan view showing two links of a chain having my improvement. Fig. 2 is a side elevation of the same.

As is clearly shown in the drawings, the device consists in chain-links 1, which may be of any suitable or convenient formas, for instance, the ordinary link belt, which is illustrated in the drawings. To such a link I secure (preferably by casting integral with the links) a pair of laterallyextending wings 2 2, the front or working faces of which are.

rearwardly beveled or inclined from the bottom edge up, so that the working face has a backward tilt as the chain moves forward in the direction of the arrow. The wings 2 2 are preferably arranged not at right angles to the line of travel of the chain but having their lateral or outer free ends slightly in advance of the inner ends by which they arev attached to the link, the effect of this arrang'e ment being to draw the material toward the center line of the chain as the chain advances and prevent the material from escaping around the outer extremity 3 of the wing. I also prefer to form the front 4 of the linksocket with a flat rearwardly and upwardly beveled or inclined face, so that the front of the socket acts as a scoop. To increase theconveying capacity of this part of the link, I prefer to extend the front 4 up above the top surface of the side member 1 of the link 1, making the top edge of the face 4 about level with the top edge of the wing 2, thus forming a scoop-front on the link. It is found in ractice that this rearwardly and upwardly beveled o-r inclined scoop-front in combina tion with the rearwardly and upwardly beveled or inclined wings 2, which are also set obliquely to the line of travel of the chain, not only increase the carrying capacity of the chain while permitting it to run more easily, but also prevent the chain climbing or riding upon the material.

I may also provide the braces 5 5 extending obliquely from the links 1 1 and engaging the rear faces of the laterally-projecting wings 2 2, preferably near the outer ends of the wings to strengthen the latter.

' What I claim as my invention, and desire to secure by Letters Patent, is as follows:

1. The combination with a conveyor-chain link of laterally-extending wings carried by said link, said laterally-extending wings having their front faces inclined rearwardly and upwardly for the purposes set forth.

2. The combination with a conveyor-chain link of laterally-extending wings carried by said link, said laterally-extending wi s having their front faces inclined rearwaidly and upwardly; together with a socket having its front face beveled rearwardly and upwardly, for the purposes set forth. v

3. The combination with a conveyor-chain link of laterally-extending wings carried by said link, said laterally-extending wings hav ing their front faces inclined rearwar .ly and upwardly; together with a socket having its front face beveled rearwardly and upwardly and projecting above the side .members of the link, for the purposes set forth.

4. In combination with a conveyer-chain link; a pair of laterallyextending wings formed integral with said link, said wings having their front faces beveled rearwardly and upwardly and extending obliquely to the line of travel of the chain.

5. The combination in a conveyer, with a suitable link, of wings projecting laterally from each side thereof, the outer free ends of the wings located in advance of their opposite ends attached to said link, the front faces of the Wings being inclined rearwardly.

6. A conveyer comprising links, wings projecting laterally from the links, said wings be ing inclined relative to the links to direct the material to be conveyed toward the links,

and brace-rods located back of the wings and extending between the links and the wings, the, outer ends of the braces being secured to the wings near the outer 'free ends of the latter. I j

7. A conveyer comprising a plurality of skeleton links, the links each formed with a socket at their rear ends to receive the front 0 end of the next succeeding link, the frontface of each socket being faced to form a scoop, wings carried by the opposite sides of each link, the inner ends of the wings being spaced apart by the width of the link, the scoop-face 35 lying between the sides of the link.

8. A conveyer comprising links socketed at one end, separate wings projecting laterally from opposite sides of each link, the forward end of each socket being faced to form a 4 MICHAEL GARLAND.
