' P. OKELL. BELT AND BUGKET'ELEVATQR.
N0. 27?;774. Patented May 15,1888.
UNITED STATES PATENT OFFICE.
PETER OKELL, or FORT MADISON, IOWA.
BELT AND BUCKET ELEVATOR.
$PEGIFICATION forming part of Letters Patent No. 277,774, dated May 15, 1883.
Application filed March 29, 1883. (No model.)
To all whom it may concern:
Beit known that I, PETER OKELL, of Fort Madison, in the county of Lee, and in the State of Iowa, have invented certain new and useful Improvements in Belt and Bucket Elevators and I do hereby declare that the following' is afull, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification.
This invention relates to certain improvements in chain-elevators; and it has for its objects to provide for an improved sprocketwheel to be employed in connection there with, and also to provide an improved meansfor securing the elevating plates or buckets, and an improved pulley over which the chain may pass, as more fully hereinafter specified. These objects I attain by the means illustrated in the accompanying drawings, in which- Figure 1 represents a view, partially in elevation and partially in section, of myimproved invention; and Fig. 2, a top view of an elevator-bucket detached.
The letterAindicates the sprocket-wheel, which is constructed in two parts, one part of which is provided with a series of dovetailed sockets, B, for the reception of the dovetailed shanks of the sprocket-teeth (3-. The two parts of the wheel are provided with apertures, through which maybe passed suitable bolts to clamp the parts together and hold the sprocketteeth in place. The periphery of the wheel is polygonal in shape, the
faces being of a length equal to the length of the links of the chain, so as to properly carry the chain when rotated. The lower part of the chain passes around a pulley, D, grooved on its periphery in such manner as to allow the links of the chain and the elevator plates and buckets to pass freely around it. The sprocket-wheel and pulley are mounted on shafts journaled in a suitable elevator-frame, E, as usual.
The letter F indicates the elevator-chain, which passes over the sprocket-wheel and the pulley in the usual manner; and the letter G indicates the elevating plates or sections. These are constructed in two parts, which are capable of being joined, as indicated. These parts are provided withlateral be of any desired shape, according to the purpose for which they are intended, and when it is required to use an elevator-bucket the parts may be formed with flat surfaces or lateral extensions, L, to which the elevatorbuckets M may be bolted, as shown in Fig. 2, or otherwise attached.
It will be seen that as thus constructed the sprocket-teeth may be removed and replaced when worn or otherwise injured; also, that the parts of the sprocket-wheel may be constructed of soft or malleable iron, which will successfully resist the strain, while the teeth may be constructed of steel, which will resist wear to the utmost extent, thus forming a durable wheel, which may be readily repaired it broken or injured.
It will also be evident that the elevator plates or buckets can be readily attached and detached, thus providing for conveniently and expeditiously repairing the elevator in case it should get out of order.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-
1. In a chain-elevator, the sprocket-wheel constructed in two parts, one of which is provided with dovetailed recesses to receive the dovetailed shanks of the sprocket-teeth, and means for clamping the parts together, substantially as specified.
2. The combination, with the sprocketwheel, constructed in two parts and having 5 dovetailed recesses and clamping-bolts, the de- 2 swam In testimony whereof I affix my signature, 10 in presence of two witnesses, this 15th day of January, 1883.
tachable sprocket-teeth provided with dovetailed shanks adapted to set in the recesses, substantially as specified.
3. The cogubination, with the chain, of the 5 elevator pl tes or buckets, supports provided with lateral lugs grooved vertically, the said plates being made in two parts and bolted upon the link, substantially as specified.
PETER OKELL.
