l/'o (lll uf/wm, it nmy/ concern.'

Be it. known that I, Env-1N H. Zinnen MAN, a citizen ot' the United States. and a resident ol Perry, in the county ot Pike and State of Illinois, have invented certain new and nsel'ul Improvements in Elevators, ot which the tollowingz, is a specification.

My invention an improvement in elevators`r and has for its object the provision ol an elevator which may be transported troni place to place and nia;7 be operated lroiu anuvi suitable source of power. and which is especiallj.v adapted for handling grain. sach as corn and Vlie-at. vegetables, such as potatoes or any other article that ina)Y be handled with a scoop shovel.

Referring to th.x drawings, Figure l is f side view ol' the improved elevator, Figs. i2 and 23 are sections on the lines '2L-'2 and 3h23 resi-)ectively et l, lfig. l is a vertical longitudinal section of the elevator. Fig, 5 is an enlarged perspective view ot a portion of the endlessl carrier. Fig. t3 a detail perspective view oi the liftingl 1nechanisln `for the damping device or movable section ofthe elevator, and Fig. T is a siinilar view of the connection between the said section and the fixed section.

rl`he present embodiment oit the invention is shown supported on a carriage, consisting of a body l, and front and rea axles 2 and 3. each axle having jonrnaled on theends thereof a pair o1 wheels Ll. A tongue 5 is connected with the front axle for convenienee in tranepal-ting the elevator, and a pair ot' standards o is secured to the front end of the body,y and at each side thereof. llaeh .standard 6 is lnaced against the bod);v by front and rear braces T and S, and at the rear ot the body a pair of uprights is arranged. each upright consisting of a snbstantially verticzl portion 9 and an inclined portion l0. the said portions 9 and lO being integral at their upper ends, and each upright has` a bearing for receivingr a shaft l1 arranged transversely ot the body.

il shaft .l2 is journaled on the standards G, at the upper ends thereof7 and the main section ot the elevator is supported between the standards and the uprights. The said inain section consists of spaced side plates, each side plate being composed of a bottom or lower Section 13, and a top or upper sectirin- 21st the said sections of each side plate ai f beingleonnected together' by a hinge l5. The hinge lo; is atthe upper edge ofthe sec- Specification of Letters Patent. Application led August 2.0L 1912.

tions and forms with the sections a species ot rale joint which permits the sections to told upwardly, but which prevents thein from iolding downwardly. A1 their opper' ends, the section.` ll are connected bv a curved plate oi hoed lo. and a .shaft ll" is joarualed between the said ends o'f the side plates adjacent to the hood. shaft 1S is journaled transversely"of the side platos at their lower ends, and stab shafts lll are jonrnaled below and in liront oit the shai't 18 on the bod): l. Each ot' the shafts l?. 1S and lt) is novided with sprocket wheels one near each end. and an endless belt or chain 2l is supported on the sprocket wheels 'of the shafts l? and 1S adjacent to each side plate'. The chains are connected at .spaced intervals by" vertically arranged slats or buckets 2i), and a floor Q3 is arranged transversely ol the side plates bet'w'een the upper and lower runs ot' the chains. The forward end ot' the said floor curved around the .shaft l? as shown at 2l in Fig. ll.. and the sprocket wheels 20 on the shafts .19 also engage with the endless chains, but with the lower runs thereof, preventing` the lower runs from sagging away from the shaft 1S.

Pulleys 25 are secured to the shaft l2. and cords orv cables 26 pass over the said pallei-s, One end of each cord is connected to a bracket 2T on the outerace ol" the adjacent side plate and the other end of each cord winds upon a dru1n`28, jonrnaled on the upper edges ot' the body of the carriage l handle 30 is provided' tor the drinn nd. a ratchet wheel 3l is secured to the drum at each end. pawl' 3L cooperates with each ratchet wheel to hold the drinn in position, and it will bo evident that when 'the pawl is released, the elevator may be raised or lowered by turning the drain in the proper direction.

The lower end of the main section of the elevator is supported bv angle brackets 33. each of which has one portion secured to the bottoni of the carriage bodyP by lneans of bolts 3e, and the other portion of each angle bracket is provided with a bearing 35, for receiving the shaft ,18.

It will be noted troni an inspection of Figs. l and el. that the side plates 13-44 are lenn'itndinalbv slotted atthe lower runs of the belts, as shown at 3G, so that the said runs of the belts are visible roni the slot. Straps 3T are riveted to the side plates and extendtransversely of the slots of each side plate. The sections vof each side plate arel Each bearing block is slidable in the guide,

and threaded rods 43 are rotatably connected with the blocks, each of the said rods being threaded through a lug 44,011 the adjacent guide 42. It will .be evident that when the rods 43 are turned in the proper direction, the shaft 17 will be moved to ward or from the shaft 18.

The shaft 18 is provided with a belt wheel 45 outside of the adjacent side plate and with sprocket wheels 46 .and 47, also outside of the side plates. The sprocket wheels 4G and 47 are connected by sprocket chains 48, but one of which is shown, with sprocket wheels 49 on a shaft 50, journaled in the ends of extension plates 51 to be later described.

A sprocket wheel 52 is journaled loosely on the shaft 18 outside of the sprocket wheel 47 and the said wheel 52 is provided on one of' its faces with one section of the clutch,

the other section 53 lof the clutch being feathered on the shaft 18, and moved toward and from the wheel. 52, by means of a lever 54 pivoted to a bracket 55 on the adjacent side plate. The said lever 54 is provided with a fork for engaging a groove 56 on the clutch section 53,' and the lever .is held in adjusted position by means of the usual latch mechanism and toothed quad' rant 57. i

Each of the extension plates 51 before mentioned, is pivoted at its inner end on the adjacent end of the adjacent plate 13, each plate 51 having a laterally extending pin 58 for this purpose. The extension plates and connected parts form an' auxiliary or loading section of the elevator. Ihe pin 58 is held, inwU shaped bearing blocks 59, each of which is secured to the adjacent side'plate 13 and the shaft is held in the bracket by means of cotter pins 60, passing through the arms of the brackets.

Thetshaft 50, before mentioned, is journalcd at the other end-of the extension plate 51 and the endless belts or chains 21 pass over sprocket wheels G1 on the said shaft 50. The endless carrier formed by the chains 21 and the slats 22 thus extends from4 the sh aft 17 to the shaft 50, and the sprocket wheels of the shafts 18 and 19 support the upper and lower runsv of lthe said chains at the .junction of the adjacent ends ofthe main and the auxiliary or loading sections of the elevator.

The lower edge of each extensionv plate 51 is rounded as shown at 62, and a bar 63 is arranged below said edge in spaced relation and is heldin place by'vmeans of straps 64,

which are riveted to the extension plates and to the bar. f

Each of the stub shafts 19, before mentioned, is journaled on a bracket 69, secured to the adjacent side plate 13, the sprocket wheel 20 being on the inner sideof the bracket.

A bracket is secured to each of the extension platesl on the outer face thereof,

and the upper end of each bracket is off-set laterally from the extension plates, and is provlded with a journal pin 71, at its upper end. A lever 72 is pivoted to each journal i pin aty one of the ends of the lever, and the said lever is held in place on the pin by a cotter pin 73. The free end of each lever 1s curved upwardly as Ishown at 74 and is proipled with a lateral outwardly extending he shaft 11, before mentioned, is square 1n cross section, and an arm 7 6 is held on the shaft outside of each upright, and each arm is provided with a square opening for receiving the shaft. The outer end of each .of the said arms is curved downwardly as shown at 77, and is pivoted to the adjacent lever 72 as indicated at 78, at the junction of the straight and the curved portions of the-said lever. A lcrank 7 9 is arranged on the shaft at one end and it will be evident 'that when the shaft 11 is oscillated by means of the crank, the auxiliary or'loading sec tion of the elevator will be swung upwardly and forwardly. ThrJ upper run of the end less carrier travels toward the hood 16, and anything dumped upon the'said carrier at the auxiliary section of the elevator will be carried toward the hood and will be delivered at the upper end thereof. The said upper end mav be raised or lowered in accordance with the height of the place to which the Vmaterial is to be delivered, and a defiecting board 80 is arranged at the upper end of the main section of the elevator for preventing the material from falling rearwardly. The loading section of the elevator may be turned up in dumping position during transportation. The loading section maybe also released from the main section by-removing the 'cotter pins 60. 1

A belt 81 from a suitable source'of power, is connected tothe band wheel 45, for operating the elevator.

The slats 22 (Fig. 5) are provided with laterally extending pins 82 rectangular in cross section and the said pins are received in similarly shaped openings in the links 21 of the chains. Each slat is also provided with an outwardly extending lug 83, at each end of its upper edge, the said lug extending over the chains.
