$PECIFICATION forming part of Letters Patent No. 683,603, dated October 1, 1901.
Application filed September 10, 1900. Serial No- 29A78. (No model.)
To all whom, it may concern:
Be it known that we, CHARLES WV. HUNT and CHARLES 0. KING, citizens of the United States, residing in WVest New Brighton, borough of Richmond, city of New York, State of New York, have invented certain new and useful Improvements in Conveyors, of which the following is a specification, reference being had to the accompanying drawings, formin g a part hereof.
Chain conveyors for carrying coal and other substances and having buckets which are pivoted between chains provided with rollers running upon tracks are usually provided with rods which extend from one chain to the other to maintain the chains and rollers in proper position during the movements of the oonveyer, the rollers and the tracks on which they run being comparatively narrow. The use of such rods, however, is undesirable in some respects. By this invention it is proposed to dispense altogether with the use of rods extending from one chain to the other and yet to secure the necessary stability of the chains and rollers under all conditions of use. To this end the rollers have a wide bearing upon the track on which they run, and the buckets are hung upon the chains close to the vertical planes of the inner edges of the bear- 1ng surface of the rollers, the overturning moment of the buckets thus becoming less than the stability of the chains-that is, the weight of the bucket, with its load, being insufficient, by reason .of the short leverage, to tilt the chains upon their bearings.
For the purpose of illustrating and explaining more fully the nature of the invention the same 1s shown in the accompanying drawings as embodied in a convenient and practical structure.
In said drawings,Figure l is a View in transverse section of a conveyor which embodies the invention. Fig. 2 is a plan view of a portion of such a conveyor, but on a different scale; and Fig. 8 is a View in side elevation, also on a different scale, a portion of the driving mechanism being also shown.
In the construction shown in the drawings the tracks A are shown as channel-irons, with the flanges turned down to give abearing for flangedlwheels or rollers B, the channel-irons being of considerable width. It is obvious, however, that single angle-irons spaced apart might be used or that flangeless wheels each short shaft 0 for convenience in the ap-- plication of the chain-links D; but obviously a single broad roller might be substituted for the two separated rollers.
- It will be clearly understood that any arrangement of the tracks and the rollers which atfords a broad bearing and permits the use of rollers, whether single or double, of suflicient Width to insure the stability of the chains between which the buckets are hung will be within the scope of this invention.
The buckets B may be hung upon the chains in any convenient manner, the point of support at each side of the bucket being so close to the inner edge of the relatively broad bearingsurface of the rollers upon the track that the overturning moment of the bucket will be less than the stability of the chain, whereby the chains remain in their normal positions on all parts of the track and under all conditions of. use and no binding between the links of the chain nor of the buckets upon their supporting-pivot is possible. Preferably the buckets are supported upon the inwardlyprojecting ends of the short shafts 0, upon which the wheels or rollers B are mounted. It will be obvious, however, that in this particular, as in others, the invention is not restricted to the precise construction and arrangement shown and described herein.
We claim as ourinvention-- 1. Ina conveyer,the combination of chains, each comprising links and pairs of rollers, the rollers of each pair being separated and the links arranged between them, a track for the rollers of each chain and buckets carried between the chains and supported therefrom, the buckets forming the only connection between the chains; substantially as shown and described. 2. Inaconveyer,the combination of chains, each comprising links, pairs of rollers and short shafts on which the pairs of rollers are mounted, the rollers of each pair being separated and the links arranged between them, a track for the rollers of each chain, and buckets hung'upon the short shafts of the chains carried between the chains and supported therefrom, the buckets forming the only connection between the chains, substantially as shown and described.
3. In aconveyer,the combination of chains, each comprising links and pairs of rollers, the rollers of each pair being separated and the links arranged between them, a track for the rollers of each chain, the width of the track and the distance between the rollers of each pair being such that a stable support is afforded for the chain independent of connections between the chains and the buckets, and buckets carried between the chains and supported therefrom,the connections between the buckets andthe chains being located close to the vertical planes of the innermost points at'wh'ich the rollers are in contact with the track, the said buckets forming the only connection between the said chains; substantially as shown and described.
rollers of each chain, the width of the track and the distance between the rollers of each pair being such that they afford a stable support for the chain independent of connections between the chains, and buckets hung upon the short shafts of the chains at points close to the vertical plane of the innermost points at which the rollers are in contact with the track, said buckets forming the only connections between said chains; substantially as shown and described.
This specification signed and witnessed this 7th day'of September, A. D. 1900.
