BIL-.LET- CONVEYER.

SPECIFICATION forming part of Letters Patent No. 633,572, dated September 26, 1899.

Application filed June 2, 1893.

To all 2071 0717, it nut concern.-

Be it known that 1, JOHN C. CROMWELL, of Cleveland, in the county of Ouyahoga and State of Ohio, have invented a new and useful Improvement in Billet-Conveyers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which Figures 1, 2, and 3 are top plan views showing successive portions of my improved conveyer, the three when united showing the entire apparatus. Fig. 1 shows a modified construction of the apparatus. Figs. 4:, 5, and 6 are side elevations of the successive sections of Figs. 1, 2, and 3, respectively. Fig. 7 is an enlarged detail side elevation of a portion of the conveyer. Fig. 8 is a crosssection of the detail of Fig. 7, and Fig. 9 is a diagrammatic perspective view showing the general arrangement of the rope-driving connections.

My invention relates to billet-conveyers, and is designed to provide an improved construction thereof wherein the billets or similar articles are carried-upon a series of rollers, which rollers are driven by an endless belt, which may be made either in the form of a wire rope, a belt, a chain, or other flexible connection, for which in the claims I shall use the general term belt. It is also designed to provide a conveyer of this general form wherein the billets may be switched off at any desired point in the length of the conveyer and by means of a side loop thereof de posit at any desired point.

In the drawings, 2 represents a drivingengine, and 3 a main shaft having gear con nections with the shaft of the main drivingdrum 4.

5 is a mating driven drum, and between thedrums 4 and 5 is located the idle drum or roller 6, against which the outer portions of the drum-peripheries bear, thus removing any side strains upon the bearings of the drum which would otherwise be present on account of the action of the belts, which are looped about these two drums and held taut by the ,usual traveling tightener 7, carried upon a wheeled truck 8, movable along a track 9 and acted upon by a suitable counterweight, so as to tighten the belt passing aroundit. V

In the drawings I have shown the belt as composed of a single continuous wire rope, which after being looped about the drums t and 5 and passing over the tightener extends thence throughout the entire length of the conveyer, returns to the starting-point, and thence is repeated, again extending throughout the conveyer and back to the startingpoint, where it is 'joined to the first end, thus giving parallel separated strand portions which move side by side throughout the conveyer, the two strands moving in the same direction and at the same rate of speed. The two strands after passing aboutthe tightener extend horizontally to and around a horizontal pulley 10. They thence extend horizontally and at an angle to the general line of the conveyer to and over two vertical pulleys 11, which space the strands the desired distance apart. Thence the strands extend forward toward the general line of the conveyer and over a double-grooved pulley 12, and thence longitudinally over the vertical pulley 13 and downwardly to and under the double pulley 14:. The strands thence extend over a small single pulley 15 to and around a large horizontal pulley 16 and again at an angle to and around the vertical pulleys 17. Then returning, the two strands pass around a double loose pulley 18, directly overand upon the same shaft as the pulley 16, and thence extend longitudinally to the starting-point at the drums at and 5.

Above that portion of the belt extending from the double pulley 18 to the driving-drum is located a framework 19, in which are mounted a series of transverse rollers 20,\vhose bearings rest loosely in suitable guides 21 upon the frame, the rollers being held in place merely by their own gravity and resting upon the strands of rope. These rollers may be grooved, as shown, to receive the separated strands and increase the amount of bearingsurface, and I prefer to so make them, though they may be made plain-faced, if desired. To support the portions of the cables beneath the rollers 20, I mount inthe frame 19 a series of grooved pulleys which are located in pairs .and preferably between the lines of the rollers 20. These pulleys 22 support the load as the billets are moved forwardly upon the rollers 20, on which they rest, and serve to insure a close contact between the belt and the rollers 20. The upper portion of that branch of the belt which extends forwardly from the double pulleys 11 serves to drive a series of rollers 20, which are mounted and driven in exactly the same manner as the pulleys 20, and to transfer the billets from the main line of the conveyer to this branch I provide a pivoted switch 23, which is arranged to contact with and deflect the billets onto a rotating turntable 24. This turn-table is provided with guard-plates 25, which constitute extensions of guard-plates 26, located above and at the sides of the rollers, as shown more clearly in Fig. 8. The guards 25 guide the billets onto the rollers 20, which carry them along at an angle to the main line of the conveyer to points where they may be acted upon by pushers 27, by which they may be moved into a heating-furnace 28. The upper part of the belt, extending from the pulleys 17 forwardly to the pulley 18, drives a series of rollers20", which are for the same purpose as the rollers 20, this branch being similarly provided with pushers 27, which move the billets into a furnace 26. WVith this branch I use a turn-table 24L, with which cooperates the curved guide-plate portion 26', which I have broken away partially in Fig. 6, so as to show the circular guiding-flange 29 upon the turn-table.

It will be understood that a branch of the conveyer similar to either of those shown may be formed at any point throughout the line of the conveyer and may extend at any desired angle thereto, so as to convey the billets sidewise to any desired point. This is an important feature of my invention, as I am enabled to move the billets to any desired point at the side of the main line of the conveyer by an extension of the conveyer itself, the rollers of the branches being driven by loop portions of the continuous belt, which may be driven from a single source of power. I desire to cover this arrangement of the continuous belt as a conveyer whether rollers are employed therewith or not. It will be noted that the rollers I employ rest upon the driving-belt by their own gravity and are thus frictionally driven thereby, that the driving-belt bears upon the rollers between their bearings, and that in the particular form shown the bearing of the belt is equalized upon the roller by the two separated strands.

In Fig. 1 I show a modified construction of my apparatus included within the scope of my broader claims, in which for the purpose of increasing the distance between the article and the belt to insure its not injuring the belt I employ a second series of rollers, which rest upon and are driven by a lower series of rollers. The latter rollers are in contact with and are driven by the cable, and the upper series of rollers carry and move the billets placed thereon. In this form the cable is driven in the direction in which it is desired to move the billets.

The advantages of my invention result largely from the use of the loop and also from the rollers resting upon the driving-belt between their bearings, since a simple and effective construction is thus afforded, which may be very cheaply made, as the bearings of the rollers may be roughly constructed with little or no machining thereon. The arrangement of the driving-belt gives a simple and effective means by means of side loops or branches for carrying the billets to any desired point and that without the use of any other power than that employed for the main line of conveyer.

Vithin the scope of my broader claims I may duplicate the driving cable or belt, using two or more of them instead of one.

The structure of the driving'belt may be varied widely, as well as the construction and arrangement of the driving mechanism, the guiding-pulleys, &c., without departing from my invention, since What I claim is l. A conveyer comprising a driving cable or belt and a series of rollers which rest upon the upper face of the cable or belt in its upper path, and are driven thereby, substantially as described.

4. A conveyer comprising a driving cable, or belt, and a series of rollers which rest upon the upper face of the cable or belt, and are frictionally driven thereby, said rollers having grooves in their peripheries engaging the 'cable, substantially as described.

5. In a conveyer, a driving cable or belt, and a substantially horizontal series of rollers resting thereupon at points between their bearings, and guideplates for the articles moving over these rollers, substantially as described.

6. In conveyers, a driving cable or belt, a series of rollers resting upon and driven thereby, andsupporting-rollers upon which the cable rests, substantially as described.

7. In conveyors, an endless cable or belt having a loop portion forming a branch extending at an angle to the main portion, and rollers resting upon the upper faces of the main and loop portions, and driven thereby; substantially as described.

9. In conveyer-s,- an endless cable or belt having loop portions thereof extending at an angle to the main portion, carrying-rollers resting upon and driven by the cable or belt both in its main and branch portions, and a switch device arranged to transfer a billet from the main portion to the branch portions, substantially as described.

10. In conveycrs, an endless cable or belt having an intermediate loop portion forming a branch extending at an angle to the main portion, rollers resting upon and driven by the cable or belt both in its main and branch portions, a deflecting-switch at the junction of the main and branch portions, and moving transfer mechanism arranged to carry a billet to the rollers upon the branch portion, substantially as described.

11. A conveyer comprising an endless cable or belt having loop portions thereof forming branches extending at an angle to the main portion of the belt, rollers driven by the main and loop portions, and an intermediate turn-table arranged to transfer the articles from the main line to the branch; substantially as described.

12. A conveyer having a line of conveying mechanism adapted to carry articles, a line extending at an angle therefrom, and an intermediate turn-table driven thereby and adapted to transfer the articles from one line to the other, substantially as described.

13. A conveyer having a line of rollers and a second line extending at an angle therefrom, an intermediate transferring turn-table connecting the lines of rollers, and a driving cable or belt which drives the rollers and is connected with the turn-table to drive it also, substantially as described.
