To all whom it may concern Be it known that I, ALoNzo T. ADAMS, a citizen of the United States, residing at East Moline, in the county of Rock Island and State of Illinois, have invented certain new and useful Improvements in Elevators, of which the following is a specification, reference being had therein to the accompanying drawing.

My inventionrelates to elevators adapted to receive grain or other materials from a wagon and elevate it to a car, crib or other place, and it consists of certain new and improved organizations and combinations of parts hereinafter fully described and then pointed out inthe appended claims.

In the accompanying drawings in which the same reference numerals refer to the sameparts in the several views, Figure 1 is a side perspective view of the elevator with the mast raised and the receiving hopper swung to position to receive the material dumped from the wagon; Fig. 2 is a detail side view of the lower end of the elevator showing the boot and its adjustable hopperreceiving jack Fig. 3 is a longitudinal view ou the line 33.of Fig. 2; Fig. 4 is a central longitudinal sectional view through the associated ends of the elevator and a receiving-hopper which .are broken away, and Fig. 5 is a sectional view on the line 5-5 of Fig. 4 and also showing certain other parts in elevation. v

The several'features of my present mvention may be embodied in a machine either stationary and permanently located or'portshaped buckets :or flights 21 having a =sliding fit in the bore of the mast and connected by a suitably driven chain 22. The mast is so pivoted upon the base as to rest when outof use in horizontal position and to be-set atan 1ncl1ne thereto when in use, its lower or receivlng end belng'mounted'un an l p-- right swinging frame 24 pivotally mounted between the beams 19-near the front end of the base and preferably concave at its upper end to receive the mast. The base is provided at its rear with an upright bracket forming a seat 25 in line with the swinging frame and adapted to receive and support the rear or free end of the mast when the latter is lowered. The mast may be raised and lowered by any suitable means and preferably for this purpose I provide a trolley-arm 27 pivotally mounted on the rear end of the base and carrying a trolleywheel 28 at its free end which underlies the .mast and is formed with a concave face to fit its curve. 1 vided near its free end with a sheave 30 l around which a rope or cable 31 passes; one end of the rope is attached to the upper end 'of an upright 32 on one side of the base The trolley-arm is also profrom whence it passes over the sheave 30 and thence over another sheave 33 at the top of a corresponding upright 34 on the other side of the base, thence down over a'third ,sheave 35 near the bottom of the'uprights and in line with a winding-drum 36 mountied in bearings on the base near the pivotal point of the trolley-arm. The-uprights 32 and 34 are suitably braced and are spaced apart sufiiciently to allow the mast to pass between them -when it is lowered. The

drum may be operated by any suitable means, and for this purpose I employ in the present exemplification a crankhandle .37 rigid .with a small s rocket wheel 38 mounted upon the outer ace of a brace 19 and which transmits motion by a sprocket chain 39 to a larger s rocket wheel 40 on ethe drum, the Wheel 38 eingprovided-with .a holding dog 41. With this arrangement when the mast is in horizontal position rest- ,ingin its seat 25 and it is desired to'tilt it .more or less, the operator winds the cable on its drum 36 and the pull of the cable being at an angle to the trolley-arm causes the same to turn on its pivot'to raise its outer or free endwhichin turn lifts the outer or free end of the mast and swings the frame 24 forward and downward. 4 The mast may be raised to its extreme or any intermediate .position and the dog 41 will hold it in position. When it is desired to lower the mast .partially or wholly the dog-is released and veyer flights. the boot and may be driven from a suitable the operator allows the mast to slowly swing down by gravity, the trolley-arm of course being cammed down by and along the mast.

affords bearings for a shaft 49 having a sprocket 50 in the boot for driving the con- The shaft 49 extends through motor 52 mounted on the base; for the latter means a projecting end of the boot-shaft 49 is provided with an exterior sprocket wheel 53 driven by a sprocket chain 54 from a sprocket wheel 55 on a short shaft 56 mounted on the base and in turn driven by a belt 57 from the motor 52, the belt being shiftable by a belt-shifter 58 between fast and loose pulleys 59 and 60,respectively, on the shaft 56. The boot carries an idle pulley 61 on an arm in position to take up the slack of the chain 54 as the mast is raised. The boot is so related to the mast that the top of the boot stands in substantially horizontal position when the mast is swung to its greatest angle of inclination, and for this purpose the mast and boot are disposed at an obtuse angle to each other. The boot supports oneend of an associated receiving hopper and in order that'it may accommodate itself to the horizontal position of the hopper for different inclined positions of the mast the boot is preferably provided with an adjustable cover 62 having side pieces 63 fitting telescopically within the boot and provided with ears 64 pivoted on the shaft 49, so that it may be trued up to horizontal when the mast is inclined at different angles. The cover is adjusted for this purpose by any suitable means such as the standards 65 on the body of the boot having a series of holes to receive holding pins.

66 entering the cover. The sides of the boot and the sides of the cover are offset or shouldered on the segment of a circle having its center or axis on the shaft 49, as shown at 67 on Figs. 4 and 5, so that the shoulder of the cover will overlie and rest upon the shoulder of the boot to take the weight of the cover off the shaft but allow the cover -to swing about it. The cover is provided with a pivotal flap or apron 68 of sheet metal at its front fitting within the front end of the boot and adapted to slide on the inner face thereof so as to always close the opening between the boot and cover as the latter isadjusted while affording access to the interior of the boot. The cover is provided with a front grain inlet or opening and a rear mouth or opening for the conveyer flights as shown in Figs. 2 and 4, the receiving hop-per discharging the grain into the top of the boot through the former and the flights entering the top of the boot through the latter so that when the shaft 49 is driven in'the direction of the arrow in Fig. 4 the flights enter the boot from above in the same direction as the grain and pass down with the grain and sweep it over the lower face of the boot and out through the mast 20. By this organization of parts the grain is not ground or ruptured by being pinched between the sprocket and flightchain as is the case with the structures wherein the grain is delivered above the boot-shaft, and the grain is'carried out of the lower portion of the'boot so that it does not fall back and till the boot as in structures where it is carried out through the upper leg of the elevator. Each flight packs and carries its grain without crushing or pinching it on the shaft and without leaving any grain behind it in the boot. Also by placing .the opening in the boot for the conveyer flights in the top of the boot instead of in its bottom the lower part of the boot is made solid and without any openings to allow the escape of such grain as would work past or below the flights and escape through a lower flight-opening after the boot was filled, and the flights press down upon or travel with the grain and are not retarded by the weight or resistance thereof as they would be if traveling in a direction opposite to that of the grain entering the conveyer.

The grain is fed into the inlet in the top of the cover 62 by a suitable receiving hop per 69, and the boot of the conveyer receives and supports one end of this hopper in adjustable and detachable relation, and with such arangement that the drive of the conveyer in the mast also drives the conveyer in the hopper when the hopper is in position in the boot. The hopper is provided with a discharge outlet at its rear endhaving a downwardly depending ring 70 fitting within the inlet of the boot. 'The cover of the boot is provided with a casting 71 embracing the sides thereof and having a vertically disposed annulus 72 providing a circular inlet and forming a bearing for a double bevel gear-ring 73. An angular or flanged collar or ring 74 sets in annulus 72 and has a horizontal upper flange 75 resting upon the upper end of the annulus 72, and is provided with a plurality of bolts 76 pro jecting through the lower portion of its skirt and taking under the base of the annulus to hold the collar in place while permit- 1 ting it to turn on the annulus. vThe flange vided with an opposite pair of upwardly sockets to removably receive the projecting ends'of the drive shaft 78 of the receiving boot so' that the hopper may be swung j around in ahorizontal plane in either direction to stand at substantially a right angle to the truck to allow a wagon to drive to osition and then swung back into place in rear of the wagon and below its tail gate as shown in Fig. 1. The hopper is provided l with a skidding leg or support 7:) at its free or outer end which is rounded onboth sides to allow the same to skid or slide over the ground when the hopper is swung in either direction, and which may be folded down upon the bottom of thehopper when the latter is detached for transportation.

In order to drive the hopper-conveyer from the shaft 49 I provide a sprocket chain 80 connecting the sprocket wheel 51 on this shaft with the drive of the hopperconveyer. The adjustable cover 62 carriesa I stub-shaft 81 provided with a combined bevel-gear and sprocket wheel .82, the bevelgear portion of which meshes'with one of the bevel-gears on the gear-ring 73 and the sprocket portion of which receives the chain 80. The cover 62 is also provided with a takeeup idler 83 for-the chain 80 when the angle between the cover and mast is varied. The shaft 78 in the hopper is in turn pro- -vided with a bevel-gear 84: meshing with the other of the bevel-gears on the gear-ring 73,

and by this train of connections including the sprocket-chain 80 the hopper-conveyer is driven from the shaft 19, the shaft 78 having a driving-sprocket -85 to drive the hopper-conveyer whose other end runs upon a sprocket wheel in the opposite end of the hopper. By this arrangement the conveyer in the receiving hopper is driven by and simultaneously with the conveyer in the mast,- the direction of movement of the parts of the conveyers being indicated by the arrows in Fig. 4, and the gears 73 and 84 mesh and demesh as the hopper is placed in or raised from operative positionon the boot. By this arrangement the hopper. is

removable from the conveyer or elevator and its driving connection is broken or its conveying mechanism is detachable from its driving mechanism by merely. disassembling the hopper and elevator as by lifting the hopper vertically from its brackets or supports, and when the arts are-assembled or the hopper is again placed on its supports the driving connection therefor is made or established.
