UNLOADING Davide.

To all whom it mar/y concern:

Be it known that I, EDWARD S. AELING, a citizen of the United States of America, residin at Rin ted, in the county of Emmet 6 and State of ewa, have invented new and useful Improvements in Unloading Devices, of which the following is a specification.

This invention relates to devices for un'- loading corn, grain and the like, and it has articular reference to that class of unloadmg devices in which means are provided for tipping or tilting the from'. part of a wagon in an upward direction to permit the contents to -gravitate over the tail end of the 16 Wagon body, together with receiving and elevating means to dispose of the material thus discharged from the wagon.

The present invention has for its object to rovlde a simple and improved device for tilting the wagon which contains the niaterial to be unloaded.

A further object of the invention is to provide simple and improved receiving and elevating mechanism. l

A further object of the invention is to construct anunloading device of the character described which shall possess superior advantages in point of simplicity, dura" bilit and general eilieieney.

With these and other Vends in view which will readily appear as the nature of the in- Yention is betterl understood, the same consists in the improved construction and novel arrangement and combination of parts will be hereinafter fully described and particularly pointed out in the claim.

In'the accompanying drawings has been illustrateda sim le and preferred form of the invention, it eing, however, understood 40 4that nolimitaton 'recise structural details therein exhibited,

Eutgjthat chan es, alterations and modificatgnsf'within t e scope of the claim may be resorted to when desired. y'

46 Inthe drawings,-'Figure 1 is a side eleva- "f tion showing` the invention in' position for operation. ig. 2 is a front view in elevation of the wagon tilting device. Fig. 3 is a perspective detail view of the actuating 50 mechanism `of the wagon tilting device.

4 is an end view in elevation and partly in section of the grain elevating mechanism. Correspondin parts in the several figures .are denoted by ike characters of reference. 55 A-frame s ucture is provided comprising .legs or uprigh 1 and 2 which are arranged is necessarily made to the Specification of Letters Patent.

in pairs converging upwardly, as shown in Fig. 1, and tilted in the direction of each other, as shown in Fig. 2, the upper ends of said legs or uprights being connected with a cap piece 3 by means of bolts 4 and brace members 5', whereby a Simple and very durable and effective frame .structure is pro-- vided and the same being made `of such dimensions as to enable u loaded wagon to be driven between the uprights 1 and 2 beneath the cap piece 3. The uprights 1, l at one end of the frame structure are provided with bearings or boxes 5 and 6 wherein two shafts 7 and S are supported for rotation, one above the other, the lower shaft 7 being provided with a spur Wheel 9 meshing with a pinion 10 upon the shaft 8; the spur wheel may thus be rotated by the expenditure of com aratively light power applied to the sha t 8 by means of a crank 411 at one end of the latter. The shaft 7 also carries a ratchet wheel 12 and a brake wheel 13, the former being engaged by a pawl 14 pivoted u on the shaft V8. Said shaft also a'ords a ulcrum for a lever 15 carrying a brake shoe 16 which is adapted to engage the periphery of the brake wheel 13, so that, by simple manipulation of the hand lever 15, the rotation of the shaft 7 may be checked. Suitabl connected with op )osite ends of the shaft at opposite sides el the spur wheel 9 are the ends o'f flexible hoisting elements, such as "ropes or cables 17, 17 which are partly wound u on said shaft and which areguided over vpu l'eys 18, 18 at opposite ends of the cap beam 3, the hoisting element 17 be-` ing guided over an additional guide pulley 19. The free ends of the hoistm elements 17, 17 are provided with termina loo s 20, 20', as clearly shown in Fig. 2 of the rawings.

A grain elevating mechanism is provided,

the same compnsmg an endless carrier 21 mounted for operation in an incl-ined trough or casing 22, t e\ lower end of which isprovided with a shoulder or offset 23 supporting one end of a ho per 24, the opposite end of which is provi ed with legsl 25 resting upon the ground'. The hopper 24 also contains an endless carrier 26, the ends of which are supported upon shafts 27, 28, the latter of whlch with a bevel gear 29 meshin pinion 30 upon the upper en the other end of whic ion 32 meshing with a bevel gear 33 upon has been'shown as being equi pd with a evel of a shaft 31,

carries a bevel pin-l 20 at the ends of the hoistin elements 1.7, 17 '-1 a shaft 54 which supports the lower end of the carrier 21 in the trough or casing 22. The hopper casing 24- is pivotally supported upon the u )right shaft 31 and is, therefore, capable of cing moved to various positions with reference to the trou h or casing 22. The shaft 34. constitutes tie driving shaft which may receive motion by means of a tumbling rod or in any other well known manner from a suitably located source of power.

yIt`will'be readily understood that under the construction hereinbefore described, the hopper casing 24 may be swung to a position approximate y at right angles to the trough or casing 22 o1' the inclined carrier 21, thus cnablin a loaded vehicle to be driven beneath t ie capy beam 3 of the frame structure including the uprights 1 and 2 which is located at a suitabledistance, slightly 'exceeding the length of a wagon, from the inclined trough or casing 22, which is supported in any suitable manner in such a way as to discharge through an aperture 35 into a corn crib or other receptacle 36. After the wagon has been driven into position, the loops 20,

are adjusted upon vthe hu s of the fronti wheels of the wagon, and the latter may now' by rotating the shafts 7, 8 by means of the cranilx 11 be tilted, as shown in Fig. 1, to such aiosition that its contents willbe discharge into the hopper casing 2 4 which has been previously swung or moved into receiving posit-ion beneath the tail gate of a wagon, and said tail gate bein obviously manipulated and opened in suc a manner as to permit the contents of the wagon box to Aescape gradually. The wagon may be retained in the Vtilted position shown in Fi 1 by means of the brake mechanism inclu ing the llever 15 which may be actuated manually, and it will be understood that by releasing the pressure upon said lever, the wagon may be gradually restored by gravity to its normal position.4 As-the contents of the wagon is being discharged into the hopper casing 24,Inot1on is im arted to the shaft 34, thus actuating the carriers 21 and 26 and causing the material discharged from the wagon to be conveyed from the ho er casing 24 into the caslng 22 of the endlxss carrier 2l, whereby the material will be elevated and discharged into the corn crib or other receptacle.

It is obvious that in the practical construction of this'device, the proportions may be no delay suitably changed so as to enable the material to be lifted to any desired elevation. It is also desired to be understood that any suitable Ameans may be em loyed for transmittin motion between t e endless carrier 21 an the carrier 26 in the yho per casing.

.The latter casing may be rendi y swung to an out-of-the-way position while the wagon which is to he unloaded is driven into osition beneath the tilting device, after w 'ich said hopper casing-may be quickly moved into position to receive. the material that is being discharged from the wagon when the latter is tilted.

The construction of the parts constituting this invention are such that the wagon tilting device, as well as the receivin and elevating mechanism, may be readi y moved from one place to another, so that when one crib has been filled, there need be little or in transferring the device to another crlb or receptacle. The construction is extremely simple and inexpensive, and the device has been found to be thoroughly cilicient for the purpose for which it is provided.

Having t-hus described the invention, what is claimed as new, is

In a device of the character described, a frame structure including pairs of uprights suitably spaced apart to permit a wagon to be driven therebetween, a ca vbeam supported by said Y airs of uprig ts, shafts supported one a ve the other upon one pairof uprightsatone end of the cap beam, guiding means upon the cap beam, hoisting elements connected with 4and wound upon the lower shaft and guided over the guiding means, said hoistm l elements being provided with terminal oops at their free pendant ends, a crank upon the upper shaft whereby said shaft may be rotated, a inion upon said upper shaft, a s ur w eel upon the lower shaft meshing wit said pinion, a ratchet wheel nd a brake wheel upon the lowe shaft, a pa l pivoted upon the up per sha t in engagement with the ratchet wheel, and a lever ulcrumed upon the uper shaft and carrying a brake-shoe eng ing the brake wheel upon the' lower shaftQ" In testimony whereof I 'allix' my signature in presence of two witnesses.
