To all IUILOHL it "may concern. 7

Be it known that l, CnAnLns O. GUs'rAvsnN, a citizen of the United States, residing at Columbus, in the county of Franklin and State. of Ohio, have invented certain new and useful Improvements in Conveyers, of which the following is a specification, reference being-had therein to the accompanying drawmgs.

This invention relates to screw conveyers for granular and other material.

The object of my invention is to provide a simple and cilective spiral flight-bearing and coupling device for screw conveyers by means of which the continuity of the screw is preserved and the conveyer may be set up at any desired height from the bottom of the conveyer-trough.

The matter constituting my invention will be defined in the claims.

I w ill now describe the details of construction and operation of my invention by reference to the accompanying drawings, in which Figure 1 represents a transverse section of a conveyertrough with parts including my improvements in end elevation. Fig. 2 represents a longitudinal section with parts in side elevation. Fig. 3 represents a vertical section show ing the union of the spiral flightbearing and the ordinary spiral of the screw conveyer. Fig. 4 represents a cross-sectional view of a modification. Fig. 5 represents a longitudinal section thereof.

The conveyer-trough A is of the usual constru ction and is supported in a well-known manner. At the place where two lengths of conveyer-screws are to be coupled together or at any other place where a bearing is desired there is secured to the angle-irons a at the edges of the trough a transverse clamping-bar B by bolts 0 and nuts, said bar having a middle longitudinal wearing-block b, as shown in Figs. 1 and 2. This wearing-block projects slightly downward centrally into the trough and is adapted to bear upon the spiral flightbearing directly below. In the lower part of the trough below the block b is secured a semicircular trough-liner C .by

means of the bolts 0 and suitable nuts, as-

shown in Figs. 1 and 2. This trough-liner will be made of any desired thickness for the purpose of setting up the conveyer at any desired height from the bottom of the trough.

The spiral flight-bearing F, which is inter- I posed between the ends of two sections of the spiral conveyor E, is itself a section of a spiral conveyer of a length to form one complete circumferential revolution, as represented in Figs. 2 and 5. It is provided with a rightangle-peripheral flange or edge f. The ends of the spiral bearing-section F are preferably secured to the ends of the spiral blades E at either side, which it serves to unite, by bolts or rivets g, as indicated in Fi s. 2, 3, and 5.

The screw-flight from w ich the spiral bearings F are formed is produced by rolling or otherwise in long sections the same as the regular spiral conveyers (w ith the difference above noted, that its outer edge is turned over or provided w ith an angular flange) and is then divided into lengths each comprising a single revolution of the spiral, w hich are then ready to be put in place between the blades E. -The flight-bearing may or may not be mounted upon a central sleeve or hub I, formed of a short section of pipe arranged the conveyer-fiights E. In the accompanying drawings I have represented the conveyer as provided with such a hub. The ends of the contiguous shafts D are securely united, as by means of a cou ling-piece J, that fits Within the ends of the ollow shafts D and extends through the sleeve I, if that be used, and the bolts e. The flight-bearing being thus interposed between two spiral conveyer-sections serves both to unite and to support them, thus making it possible to build up a continuous spiral conveyer of any desired length. This flight-bearing revolves the clamp and wearing-block over the top of the trough. The fli ht-bearing above described and illustrated in Figs. 1 and 2 serves for conveying material of a granular or gritty nature.

When it is desired to convey material which is not of a granular or gritty nature, I may modify the construction as shown in Figs. 4 and 5. In this modification the stituted rollers which proj ect slightl through the trough, as shown in Figs. 4 an 5. The clamp-bars P are provided centrally with journal-boxes h, as shown in Fi 5, and the top bearing-roller b is mounte by its axle in said bearings, so as to bear upon the spiral to aline with the hollow shafts D, that carry onthe trough-liner C and is held in place by i liner C is omitted, and in its place are subflight-bearing-F. Near the bottom of the trough and at each side is mounted a roller 1 whieh are supported by their shafts in brackets it, having suitable eyes-for the axles and the rollers, as shown in Fig. 4. These rollers are of the same length as the spiral flight-bearing F. Of course rollers of larger or smallendiameter may be used for varying the height at which the flight-bearing is supported above the bottom of the trough. The parts of my bearing device may be readily assembled and are very. efi'ectiverand durable in operation.. v

4. In a screw conveyer, the combination with two alining flight-sections and a trough in which they are mounted, of a spiral flightbearing interposed between the ends of the said flight-sections and comprising a section of a spiral conveyer, a bearing carried by the trough upon which the said spiral flight,- bearing rests, and a bearing arranged above the said spiral flight-bearing and engaging therewith for holding it down and in place in the trough, substantially as set forth.

5. In a screw conveyer, the combination with two alining spiral flight-sections, E, of a spiral flight-bearing interposed between the ends of the said flight-sections, andcomprising a section of ,a spiral conveyer provided at its edge with a peripheral bearing-flange, and means for uniting the spiral flight-bearing with the ends of the spiral flight-sections, substantially as set forth.
