' Y ELEVATOR.

To all whom it may concern Be it known that 1,,AL0NZ0 (T. ADAMS, a' citizen of the United States, 1 residing at East Moline, in the county of Rocklsland 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 invention relates to that type ofelevators having an adjustable hollow I mast used to elevate grain and other materialsto bins, cars and other places, and it is especially directed to certain new and useful organizations and arrangements of parts for supporting and raising and lowering the mast. a The invention consists in the matters here inafter disclosed and then pointed out in the appended claims.

In theaccompanying drawings illustrating a practical embodiment of mypresent invention and in which the same reference numerals indicate corresponding parts in the several views, i r 1 Figure 1 is a side View, of an elevator exemplifying my invention arranged for use and with the receiving hopper in position to, receive the material to be dumped from the wagon, the upper end of the elevator being broken away; Fig. 2 is a detail plan View of the rear portion of the baseor body with the winding-drum and associated parts for the trolley-arm cable; Fig. 8 is a sectional view on the line 3,3 of Fig. 5; Fig. 4: is a detail view of the elevator vand its. trolley-arm in elevation, andFig. 5 is a side view ofcertain parts shown n F 1g. 1 but with the elevator swung downv to its inoperative position. 1 a

The elevator maybe either stationary and permanently located orit may be portable, and for this latter purpose a suitable base or body may be employed, consisting in the present instance of parallel beams '19 suitably connected and spaced apart, and preferably is in the form of a truck supported upon front and rear wheelsas clearly shown The elevator comprises a tubular hollow mast 20 preferably made of a suitablei diaineter of well-tubing, anda conveyer comprising an endless series of correspondingly shaped buckets or fl ghts 21 havmg a'slid- Specification of Letters Patent. a Patented 0613. 20, 1914- Original application fi1ec 1 Mareh'25, 1e09, SeriaLNo. 485,640. I, niviaea and A 15, 1913. Serial nevarsss. p

this application filed August ing fit in the boreof the inast connected by, a suitably driven chain 22. present exeinplification ,the flights are In t the notchedor recessedto approximately their centers and therchainrests inthese notches 1 be ng suitably connectedto each, flight in suchfnianner as to hold the same approximately-at right angles to the cha n, and the return runtravels above orupon the upper side ofthe niast so that the notches in the tiona's-shownin Fig. 5 and to be setatan incline thereto when, in use. To accomplish this result I mountthe mast nearits lower or receiving endin an upright swinging frame 24lpivotally mounted between two of; the I beams, 19 near the front end of the base so as to swing forwardly and downwardly and pref-I erably concave at its upper end to receive the mast. The base is provided at'its rear endwith an upright bracketforniinga 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 asshown in Fig. 5. vVhen the rear end of the mastis raised the frame 24: swings forwardly and downwardly and carries the '85 mast bodily outward and forward so that it clears the front axle of the wagon and, its

frontv end is beyondthe forward end, ofthe basevor truck and can swing down to approximately, the levelivof the ground, and

i when it swings back to horizontal position it is, drawn] or carried bodily rearward so that. its lower or front endis drawn up wardly and in toward the base or truck and will not interfere with horses hitched to a suitable tongue, etc, attached at 26 p to, the

truck to transport the ele vator 'froln place to place. i

To raise and lower; the mast I provide a trolley-arm 27 pivotally. mounted ;on 'the base and carrying a trolley-wheel28 at its freeen'd The trolley-arm underlies the beams 19 approximately over the rear axle of' the truck anclfspaced apart sufliciently to overlie the seat 25 when the-arm is lowered;

vmast and'is pivotedfonthe base near the rear endfandf it consists of a pair of angle) bars "pivoted respectively to two of the the bars are suitably connected by cross braces 29 to form a rigid structure and carry the revoluble trolley-wheel between their free ends, the wheel preferably having a concave face to fit the curve of the mast. The arm is also provided near its free end with a sheave 30 around which a rope or'cable 31 passes; one end of the rope is attached at the upper end of an upright 32 fixed on oneside lowered.

The drum may be operated by any suitable means, and. for this purpose I employ in the present eXemplificati'o'n a crank han dle 37 rigid with a small sprocket wheel 38 mounted upon the outer face of the base and which transmits motion by a sprocket chain 39 to a larger sprocket wheel 40 on the drum. The wheel 38 is provided with a holding dog 41. These parts are clearly shown in Figs. 1 and 5. The uprights 32 and 34 are suitably braced as shown at 42. I/Vith this arrangement when the mast is in horizontal position resting in its seat 25 and it is desired to tilt itmore or less, the operator winds the cable on its drum 36 and the pull of the cable being at an angle to the trolleyarm as seen in Fig. 5 causes the same to turn on its pivot to raise its outer or free end which in turn lifts the outer or free end of the mast and swings the frame 24 forward and downward to the position shown in Fig. 1. By this arrangement the receiving end of the mast is swung down to ap-' proximately the level of the ground or floor on which the machine stands so that the top of its angular boot 48 stands approximately horizontal and the usual associated receiving-hopper 69 is below the level of the endgate of a wagon and is in position to receive the contents of the wagon when it is dumped therein. The mast may be raised to its extremeor any intermediate position and the dog 41 will hold it in position. I When it is desired to lower the mast partially or wholly the dogis released and the operator allows the mast to slowly swing down by gravity, the trolley-arm of course being cammed down by and along the mast.

The upper end of the mast carries a bearing for a suitable sprocket wheel over which theconveyer-chain runs, and its lower end is provided with the boot angular 48 which afiords bearings for a drive shaft 49 having a sprocket in the boot for driving the conveyer flights, the shaft 49'extending through the boot and being suitably connected with the tumbling rod (not shown) of a horse power or driven from the head-shaft or from asuitable motor mounted on the base. The boot forms a support for one end of a receiving hopper 69 which is mounted'so as to be swungout of the path of the loaded wagon to allow the latter to move to position to dump its contents and then swung to place in the rear of the wagon to receive the material dumped therefrom. The receiving hopper is preferably provided with a conveyer driven from shaft 49, and its discharge forms a detachable and horizontally adjustable connection with the top of the boot.

This application is a division of my earlier filed application bearing Serial Number 485,640, filed hfaroh 25, 1909.
