SIDE TROUGHING-BOLL FOR BELT CONVEYERS.

Specification of Letters Patent.

Patented Aug. is, 1912.

application filed April 24, 1912. Serial No. 892,793.

T 0 all whom it may concern.

Be it known that I, EDWARD CUnmnr, citizen of the United States, residing at Tocele, in the county of Tooele and State of Utah, have invented certain new and useful Improvements in Side Troughingllolls for Belt Conveyers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention has relation to improvements in side troughing rolls or pulleys for belt-conveyors; and it consists in the novel details of construction more fully set forth in the specification and pointed out in the claims.

In the drawings, Figure 1 is a side elevation of a portion of a belt-conveyer showing my invention applied thereto; Fig. 2 is a cross-section through the upper lap of the belt, showing a side elevation of my invention, and carrier therefor, parts being in section; Fig. 3 is an end view of the side troughing pulley; and Fig. 4 is a longitudi nal middle section on the line 4-4 of Fig.

The present improvement is particularly directed to the side troughing rolls for belt conveyors and has for its object to provide a roll which will insure a direct travel of the belt without the objection of lateral sway or displacement thereof under a load, the roll at all times acting as a guard bearing on the edges of the belt, and constraining the latter to adhere to its prescribed course. The roll further serves to maintain a positive trough in the upper belt-lap as will be fully apparent from a detailed description of the invention, which is as follows:

Referring to the drawings, B represents an endless belt operating in conjunction with a series of troughing roll carriers, C, one of the terminal pulleys P over which the belt asses, and a portion of the chute D whic discharges the material onto the belt being here illustrated in a conventional way, no claim being made to these features. The troughing rolls or pulleys usually comprise a series of intermediate cylindrical members 1, and suitable side members, and the return rolls comprise cylindrical members 2, as well understood in the art.

In the present improvement the side members of the troughing rolls comprise each a cylindrical body portion 3 or roll proper, and an outer flaring head or flange 3 formed integrally with the portion 3. The flange 3 is preferably conical, the elements of the peripheral surface thereof being inclined sul'istantially at an angle a of thirty degrees to a plane at right angles to the axis of the body portion 3, or at an angle of sixty degrees to said axis. In practice, the side rolls are mounted on spindles 4 inclined at an angle a of thirty degrees to the horizontal, whereby the vertical element of the conical surface of the flange 3', bearing iminediately against the edge of the belt B, will lie in a plane disposed at right angles to the plane of travel of the belt. Thus in Fig. 2 the element 0 engaging the edge of the belt is vertical or lies in a vertical plane, the belt traveling in a substantially horizontal plane. 'Duringlthe rotation of the side roll there will always be an element of the conical peripheral surface of the flange 3 disposed at right angles to the horizontal plane of travel of the belt, thus serving as a guard for the belt and preventing lateral shifting thereof. The edges of the belt (or web) will accordingl be constrained to take the course prescribed for them by the positions of the side rolls, and no deviation from such course is possible, the flanges 3' at all times serving as positive side guards over which the belt can not climb or creep. The angle of thirty degrees defining the flare of the heads or flanges 3 need not necessarily be adhered to, and if changed, a corresponding change in the dip of the spindle 4 would obviously be necessary in order to bring the top element of the cone, or that engaging the edge of the belt to a vertical, or into a plane at right angles to the horizontal travel of the belt. true conical surface (for the flange 3') is the most desirable, as the elements composing it are straight lines, although I wish to include within the scope of my invention, any flaring head which will operate as an equivalent.

The distinctive character of the side roll here described is that it comprises two distinct portions, to-wit, the portion 3 for the support of the side of the belt, and the portion 3' for guarding the edge of the belt.

Having described my invention what I claim is 1. In combination with a conveyor belt, a side troughing roll comprising a body ortion for the support of the side of the elt, and a terminal conical flangeor bead flaring outwardly for engaging the edge of the belt.

2. In combination with a conveyer belt, a

I side (roughing roll comprising a cylindrical body portion over which the side of the belt travels and by which it is supported, and a terminal conical flange bearing.against the edge of the belt,the said roll being mounted to ermanently present an element of its conical surface into a plane disposed substantiall .atright angles to the plane of travel 0 the belt.

3. In combination with a'eonveyer belt, a side troughing roll having a conical forma- In testimony whereof I afiix my signature, in presence of two witnesses.
