CONVEYER.

SPECIFICATION forming part of Letters Patent No. 373,389, dated November l5, 188.7. Y

Application filed August 1U, 1887. Serial No. 246,638. (No model.)

To all whom it may concern:

Be it known that I, J ONATHAN GREAGER, a citizen of the United States, residing at Gincinnat, inthe county of Hamilton, State of Ohio, have invented certain new and useful Improvements in Conveyors, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to those conveyers which consist of an endless belt, band, or carrier passed around drums at the opposite ends of a supporting'frame; and my improvement comprises a novel combination of devices which prevents lateral spreading and a consequent loss of materials placed upon the belt, the details of said devices and their peculiar mode of operation being hereinafter more fully described.

In the annexed drawings, Figure lis a plan of one end ofthe main frame of my improved conveyer. Fig. 2 is a similar plan, but showing the endless belt applied to the frame. Fig. 3 is an enlarged transverse section of the frame, taken in the plane of one of its rollers. Fig. 4 is an elevation of one of the conical heads.

A A' representapai'r of side beams orguides of the main frame, which structure may be of any desired length and width, and may be either horizontal or inclined, according to the duty required of the conveyer.

B represents one of a number of cross-beams employed for retaining the guides A A' in their proper parallel position.

C represents one of a series of transverse shafts, whose ends enter boxes or bearings D D', fitted within the guides A A', each of said shafts being provided with a roller, E, and apair of conical heads, F F', the smaller ends of which are somewhat larger'in diameter than the rollers., Interposed between these conical heads and the guides A A', and mounted upon Y the shafts O, are antifriction washers G G.

H represents one of the large drums applied to the opposite ends ofa conveyer-frame, said drum being here shown as attached to a transverse shaft, I, journaled in brackets J J', secured to the main frame, said brackets being provided with lugsjj, carrying smallvertical rollers K K', for a purpose that will presently Y appear.

L represents the endless carrier, which may be composed either of leather, rubber cloth, wire, or woven fabric, or other suitable flexible material, the width of said carrier or belt being about equal to the length of roller E, as seen in Fig. 3.

m m' represent rows of stitching, rivets, or other attachments wherewith a pair of exible wings, M M', are secured upon the carrier L and near the opposite margins thereof. These wings extend the entire length of'thecarrier, and are sufciently wide to rest upon the conical peripheries of the heads F F', and then extend up about to the top of theside beams,AA'.

N represents transverse cleats or other conductors, which may be secured to the band L; but these devices must not be attached to the wings M M', as such an attachment would destroy the flexibility of the latter.

The operation of my conveyer is as follows: The wings M M' are first secured to the opposite margins of the band L, and the latter is then passed around the drums at the ends of the frame, the extremities of said wings and band being subsequently united to form an endless carrier, to which power is applied either at the pulley O` or gear-wheel P. As the band proper, L, rests upon the rollers E, 1t is kept perfectly level in the direction of said rollers; but the wings M M', being carried by the conical heads F F', are necessarily inclined at the same angle, and by extending them up to the top of frame A A said wings serve as fenders, that prevent dirt or other material falling oft' at the sides of said band, and thus clogging up the operative parts of the con- The flexible wings maintain this inclined position until they reach the end of the frame, at which time the tension or strain ex-. erted by the drum H against the carrier causes said wings to gradually bend over to a horizontal position, as clearly shown in Fig. 2, the small vertical rollers K K' being so located as to prevent chafng of said wings against the ends of the guides A A' when the wings first begin to turn down. It will thus be seen that the changing of the wings from an inclined to a horizontal position, or vice versa, is done so gradually as not to injure the materials of which they are-composed, and on this account the conveyer will last for along time.

ICO

The cleats N or equivalent devices prevent the material slipping along the belt when the frame is pitched at :L steep angle. Finally, in some cases the heads F F' may loc integral with the rollers E; but it is preferred to make them separate, in order that each head may re volve independently.

I claim as my inventionl. In a eonveyer,a supporting-frnmcgi shaft', C, and a roller, E, :md independently-revolving conical heads F F', journaled on said shaft, one head at each end of said roller, in con1bination with an endless carrie1',L, havinglexible side wings, M M', as herein described.

2. The combination, in :i conveyer, of frame A A', shafts C, rollers E, separate conical heads F F', washers G, driving-drum I-I, and endless carrier L, which carrier has ilexible side Wings, M M', for the purpose described.

3. A conveycnframe provided with hori 2o zontal rollers E, separate conical heads F F', driving-drum I-I, and vertical rollers K K', 'for the purpose described.

In testimony whereof I affix my signature in presence of 'two Witnesses.

JONATHAN CREAGER.
