CONVEYER-BELT.

SPECIFICATION forming part Of Letters Patent N0. 705,876, dated July 29, 1902. Applioation' filed May 31, 1902 Serial No. 109,601. (No model.)

To all whom it may concern.-

7 Be it known that I, WILLIAM J. SELLEOK, a citizen of the United State's,residing at Riven side, county of Fairfield,State of Connecticut, have invented a certain new and useful Improvement in Conveyer- Belts; and I 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 pertains to make and use the same, reference being had to the accompanying drawings,

which form a part of this specification.

My invention relates generally to convey: ers, and more particularly to endless flexible conveyer belts which are given a troughshaped cross-section while carrying the material.

In order toprevent the material carried. by the conveyer from falling off the side edges thereof, it is desirable to provide in-' clined guides'beneath theconveyer-belt to maintain the sides at a higher level than the center thereof. The transverse bending of the belt necessary toincline its sides results in the belt soon Wearing outand breaking along the lines between the central and side portions. to construct conveyer-belts with a central horizontal section andsidesections adapted to be inclined with respect to the central sec-' tion to form a trough. Theside sections have either overlapped the edges ofthe cen-.

tral section and been secured thereto by rivets passing through the overlapped portions or strips have been interposed between and secured to the adjacent edges of the central and side sections. It is evident,=however, that the objection above noted; is not avoided in either of theconstructionsmemf It has been proposed heretofore the wear to which similar belts heretofore constructed have been subjected.

A further object of myinvention is to provide a conveyer-belt which will be simple in construction, inexpensive in manufacture, and durable and efficient in use.

My invention, generally stated, consists in a conveyer-belt composed I of a central and side sections flexibly unitedat their adjoining edges by interlocked lacings.

My invention willbe more fully described hereinafterwith referenceto the accompanying drawings, in which the same is illustrated as embodied in a convenient and practical form, and in which- Figure 1 isacross-section showing my conveyer-be1t supported by guide-rollers; Fig. 2,

a fragmentary plan view of my-improvement, and Fig. 3 an enlarged sectional fragmentary view showing the means for uniting the adjoining edges of the central and a side section.

Similar reference characters are used to indicate similar parts in the several figures of the drawings.

Reference-letter A designates the central section of the conveyer-belt, to the side edges of which are flexibly secured side sections A and A Suitable guides are provided for supporting the central section A in a horizontal position and maintaining the sidesections A and A in inclined positions, so as to impart to the conveyerbelt a trough-shaped cross-section, thereby preventing the material which is carried'on the belt from falling oif of the sides thereof. -In Fig. l of the drawings I have indicated a central cylindrical roller B for supporting the central section A of the conveyer-belt, while side rollers B and B support the side sections A and A of the conveyer-belt in the inclined positions indicated. The roller B is suitably journaled in the com veyer-frameas, forinstance, by means of concentric pins b,.while similar pins 1) and b rotatably support the inclined rollers 13 and B v In order that the side sections may freely move relatively to the central section without bending either the central or sidesections, I have provided lacings which pass through openings in the adjoining edges of the sections and which serve as hinges to permit the relative movement between the side and central sections of the conveyer-belt. A lacing a, preferably in the form of a spiral, passes through each edge of the central section at comparatively short intervals, as indicated in Fig. 2. A similar spiral lacing a passes through the inner edge of the side section A at intervals corresponding to the spaces between the convolutions of the spiral lacing a. The portions of the spirals a and a which project beyond the edges of the respective sections are overlapped, so as to form a series of registering loops, through which is passed a flexible wire or, preferably, a leather thong O. A spiral lacing a passes through a series of perforations in the inner edge of the side section A to engage a spiral lacing a, secured to the adjoining edge of the central section A. The projecting portions of the convolutions of the spirals a and a overlap, so as to form a passage, through which is inserted a leather thong 0 Before the leather thongs C and C are inserted through the overlapped lacings the latter are preferably flattened, as indicated in Fig. 3, to form a passage-way of the requisite size to receive the thongs O and C The lacings are securely held in the edges of the sections of the belt and are not required to move in the openings therein when the side sections assume the inclined positions to form a trough-shaped cross-section. The movement of the side sections with relation to the central section is permitted by the movement of the overlapped lacings with respect to each other. W'hilo the side sections may freely move into the requisite inclined positions, they are rigidly secured to the central section owing to the thongs O and G which couple together the overlapped lacings.

The material of which the sections of the conveyer is formed may be leather, rubber, cloth, wire, woven fabric, or any other suitable flexible material. The lacin gs a, a, and a are preferably formed of wire.

From the foregoing description it will be observed that I have invented a conveyorbelt capable of assuming a trough-shaped cross-section to support the carried material tions, of a hinge flexibly uniting said sections composed of parts movably joined together and rigidly secured to the adjoining edges ofsaid sections.

2. The combination with aconveyer-belt composed of a plurality of longitudinal sections, of lacings passing through the adjoining edges of said sections, and means for flexibly nnitingsaid lacings.

3. The combination with a oonveyer-belt composed of a plurality of longitudinal sections, of coil-spring lacings passing through each of the adjoining edges of said sections,

and a thong extending through the overlapped convolutions of the lacings.

4:. The combination with a conveyer-belt composed of a plurality of longitudinal sections, of coil-spring lacings having elliptical convolutions passing through the adjoining edges of said sections, the projecting portions of said convolutions being overlapped, and a leather thong extending through the registering overlapped convolutions of said laclugs.

5. In a conveyer-belt, the combination with central and side sections, of a hinge flexibly uniting said sections composed ofparts movably joined together and rigidly secured to the adjoining edges of said sections.

6. In a conveyor-belt, the combination with central and side sections, of lacings passing through the adjoining edges of said sections, and means for flexibly uniting said lacings.

In testimony whereof I sign this specification in the presence of two witnesses.

WILLIAM J. SELLEOK.
