Application nea February 28,1906. serial No. 303,428.
T0 all whom it may concern,.-
Be it known that I, JOHN Ross, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented new and useful Improvements in Bucket Elevators, of which the following is a specification.
This invention relates to an improved construction of turn-table and hoisting-gear for elevators such as are used for unloading vessels and for other pu oses where material of various kinds is kto e conveyed from one level to another.
The invention is applicable more particularly to elevator mechanism for discharging brokenrock or stone from a scow onto the Wharf, where the material requires to be raised to a higher level; and it has for its object chiefly to provide improved means for adjusting or changingthe position of the elevator at will to work at .different angles and for operating the elevatorunder every condition or degree of adjustment without disconnecting the elevator from the power or throwing it out of operation. Y
To these and other ends my said invention comprises certain novel construction and combination of turn-table and hoisting-gear, as hereinafter described, and pointed out in the claims at the end of this specification, reference being had therein to the accompanying drawings.
Figure 1 is an elevation, partly in section, of the part of an endless-chain and bucket elevator to which my improvements pertain, the ladder or frame, the turnetable, and the Voperating-gear being shown in transverse section. Fig. 2 is a side view of the parts represented in Fig. 1. Fig. 3 is a plan or top view of the stationary bed-plate beneath the turntable and the foundation-timbers. Fig. 4 is a front elevation of the bed-plate, and Fig. 5 is a side view of Fig. 4. Fig. 6 is a top view of the turn-table, and Fig. 7 -is a front elevation of the same. Fig. 8 is a side view of one of the trunnion-boXes on the ends of the ladder. Fig. 9 is a face view of one of the bearingboXes for a trunnion. Fig. 10 is a side view of Fig. 9. t
The stationary bed-plate has a flat top a, formed with a circular bearing-surface 2, with which engages an annular bearing-surface on the bottom plate l) of the turn-table. The
these last-mentioned shafts is coupled to or j connected in any suitable manner with the engine-shaft from which power is supplied to operate the elevator, such as through a clutch or by a belt and pulleys, whereas the other shaft 12, running idly, is arranged to carry an idle pinion 16.
From the shaft 10 the power is applied to the upright shaft 17, eXtendingthrough the center post of the turn-table, by means of a bevel-gear 18, keyed on the lower end of the shaft 17, and a beveled gear 21, keyed on the upper end of the shaft. A beveled pinion 22, keyed on the shaft 20, connects the latter shaft with the upright shaft 17.
Like the pinion 16, that in mesh with the lower gear 18, av beveled pinion 23 is placed onthe shaft 20 oppositeto the driving-pinion 22, and being loose on the shaft 20 it is arranged to counteract the angular strain of the gears 18 21 on its shaft as the power is transmitted through the gear 18 to the pinion 22 on the driven shaft.
The tubular post 8 on the under side of the turn-table is lined with Babbitt metal, andan lantifriction-bearing 25 is interposed between 'the top face of the turn-table at the center bearing 24 and the lower face of the beveled gear 21 The opposing faces of the bed-plate and the turn-table are faced, as seen in Figs. 1, 3, and 4, to give a firm bearing around the center post and also around the outer margin of the bed-plate, the intermediate vpart ,of the surface on both bed-'plate and turn-table being recessed to reduce the extent of frictional contact.
The standing sides 30 and ends 31 of the turn-table are integral with the bottom plate. On the standing sides are hubs 29, that form bearings for the horizontal Shaft 20 and also trunnions for the lower ends of the elevatorframe.
The turn-table b, the center post 8, standing sides 30, and hubs 29 and the end pieces Babbitt metal to reduce the friction.
31 are formed in one piece. The standing sides have slanting top edges, as seen at 32, Figs. 2 and 8, t0 which are fitted top plates 33 to cover and protect the gearing from dust and particles of rock that are liable to drop.
from the buckets.
The surface of the bed-plate and the turntable mutually cover and protect each other and the bed-plate in turn protects the pinions and drivin -gear that are situated beneath the bed-p ate, as the boxes and bearings that carry the drivin -shafts are located within the sides of the be -plate.
The construction of the parts carried by the turn-table and those mounted on the bed plate is such that the turn-table can be moved around the upright shaft 17 as an axis, and the direction as well as the angle of the elevator-'frame can be changed as conditions require without disconnecting the power oraffecting the operation of the hoisting mechanism on the elevator-frame. The hoisting power is applied yto the chain of buckets by sprocket-wheels 36 37 and a chain belt 38 on both sides of the frame connecting both ends of the shaft 20 with a bucket-operating shaft 40 on the frame. The bucket 7c of the form usually employed in these elevators is fastened to four endless cables 41 42 43 44, of which the two inner ones 42 44 transmit the power from the bottom shaft 20 to the top shaft 45, carried in bearings 46 on the upper end of the elevator-frame, and the outer ones 41 43 support the buckets and connect them together in an endless chain or row. The cross-bars 48 are fastened to the cables 41 43 by straps passing around the cable and riveted to the bars and pouring Babbitt metal between the strap and the strands of the cable. This forms a simple and effective means of securing the bars to the cables. The buckets are fastened to the bars 48 by bolts or rivets. Removable caps should be provided on the boxes that carry the shafts 10 12 under the bed-plate. As thus constructed and arranged this mechanism is es ecially adapted for handling and adjusting t e elevator such as is employed for conveying rock and other heavy material from a lower to a higher level.
The turn-table is constructed with a view to relieve the center-post of the weight and strain of the load to the best advantage, and the arrangement of the gears and pinions is such that the turntable is readily rotatable even under a heavy load.
By moving the elevator-frame on its trunnions the degree of inclination is changed, and by rotating the turn-table on its axis 17 the frame can be set in any desired direction aroundthe circle.
The elevator-frame is supported from the upper end in the usual manner by cables and tackle, the arrangement and application of which are too well known to require a detailed description.
All parts of the elevator not necessary to a clear understanding of the invention are omitted from the drawings and the description.
What I claim as my invention, and desire' standing sides thereon, hubs on the standing sides and cradle-blocks on the outer faces of the standing side under the hubs, in combination with an elevator-frame having boxes on the lower ends provided with a semicircular cap-piece.
