To @ZZ whom it may concern:

Be it known that I, FRANK JESTRAB, a citizen of the United States, residing at Pisek, in the county of Walsh and State of North Dakota, have invented a new and useful Grain Unloader and Elevator, of which the following'is a specification. l

Myinvention is an improved portable grain elevator and unloader for transferring grain from a wagon to a c ar, granary, or the like.

My invention consists in the peculiar construction and combination Vfof devices hereinafter fully set forth,and pointed out in the claims.

In the accompanying drawings, Figure 1 is a vertical sectional view of a grain unloader and elevator constructed in accordance with my invention, showing the elevator raised to its operative position and withv its lower end in communication with the discharge end of the grain-receiving hopper. Fig. 2 is a side elevation of the same, showing the elevator folded over the truck. Fig. 3 is a top plan view of the same. Fig. 4 is a vertical transverse sectional view of the same. Figs. 5, 6, and 7 are detail views of the hopper and the means for discharging the grain therefrom to the elevator, the said figures illustrating modified forms ofmy invention.

In the embodiment of-my invention l p rovide a receiving-hopper l, which is supported on a truck-,frame 2,that is provided with supporting-wheels 3, whereby it may be readily moved from point to point and whereby the receiving-hopper may be readilyrun undera Wagon-body or the wagon backed over the hopper. It Will be understood that the size and proportion of the parts of the hopper and truck must be such 4as t enable the same to be used as hereinbefore stated. The hopper is provided with a discharge-openi ng 4 at its rear end ,to which a suitable discharge mechanism, located in the bottom of the hopper, conducts. In the form of my invention shown in Figs. 1, 2, 3, and 4 a `conveying- Worm 5 is located in the i bottom of the hop-A per and is adapted to force the grain from the hopper to the dischargefopening 4. The front end of the Worm is provided with an extended shaft 6, to the front end of which is keyed a beveled gear-wheel 7. The same is engaged by'a similar gear-wheel 8 on a shaft 9, which is transversely disposed with relation to the worm and is journaled in suitable bearings 10 under the trucktrame. A sprocket-wheelll is keyed to the said shaft 9, and the same is further provided with a power-pulley 12 or other suitable means for transmitting power thereto from a suitable engine or other sourceof power.

Standards 13 rise from the sides of the truck-frame, at the rear end thereof, and between the said standards the trunk 14 of the elevator (generically indicated at l5) is pivotally supported on a shaft 16, which extends transversely through the trunk and is journaled in bearings 17, with which said stand- 'ards 13 are provided. The said trunk at its lower end is provided with an intake 18, which communicates with the discharge-opening 4of the hopper when the trunk is turned on its pivotal support to the position indi'- cated in'Fig. 1 of the drawings, and the said trunk'is provided at its upper end with the usual discharge-spout 19. l Any suitable form of endless movable elevating apparatus (indicated at 20) may be employed in the trunk, and the same is driven by the coactiontherewith of the pivotal shaftlG, which hence becomes the power-shaft of the elevator. For the purposes of illustration YI have herein shown the shaft 16V as provided with sprocketwheels 2l, which engage'and operate endless sprocket-chains 22, that carry the elevatingbuckets 23. The said shatt 16 is provided at one end with a sprocket-wheel 24, and the same is connectedto the sprocketwheel 11 on the shaft 9 byan Aendless sprocket-chain 25, whereby power is communicated from y the 'shaft 9 not only to the feed-worm, but also to the elevator, so that the worm and elevator operate in unison. It will be further understood that by this construction and combination of devices, whereby power is communicated from the power-shaft 9 to both the feed-worm and the elevator, the elevator shaft when it is disposed over the truck-frame in the position shown in Fig. 2. When the elevator is disposed in its'operative vertical position, (shown in Fig. 1,) the same is locked inl such position by a lock-bar 26, which is does not become disconnected from the power-V i IOO pivoted to one side of the truck-frame at the rear end thereof, as at 27, and is secured to the opposite side of the truck-frame by a screw or other suitable device, as at 2S. It will be understood that the said lock-bar must be unshipped and turned out of the way of the elevator-trunk before the elevator can be turned on its pivots and disposed over the truck, as shown in Fig. 2.

`In the modified form of my invention shown in Fig. 5 I discard the feed-worm 5 and employ in lieu thereof an endless conveyer 29 in the bottom of the hopper to move the grain to the discharge-opening 4 thereof, the said endless conveyer being directly operated by the power-shaft 9.

In the modied form of my invention shown in Fig. 6 I employ a reciprocating feeder 30 in the bottom of the hopper in lieu of either of the devices hereinbefore described and connect the said reciprocating feeder, by means of a link 31, with a crank 32, with which I provide the power-shaft 9.

In the modified form of myinvention shown in Fig. V I provide the hopper with a bottomboard 33, which is pivoted at its end proximate to the discharge-opening 4 of the hopper and extends in an inclined direction lengthwise in the hopper, and said bottomboard may be inclined to any requisite angle in order to discharge the grain in the hopper by gravity through the opening 4 to the elevater.

Other modifications may be made without departing from the spirit of my invention.

Having thus described my invention, I claim 1. In combination with a truck having a receiving-hopper, and standards which rise from the sides of said truck, beyond and above the discharge end of the hopper, an elevatortrunk having a pivotal shaft at a point intermediate of the ends of said elevator-trunk and journaled in bearings on said standards, one end of said trunk when lowered communicating with the discharge end of said hopper, and an endless traveling elevating mechanism in said trunk, said elevating mechanism being driven by s aid pivotal shaft, the latter having a pulley, a feed-worm in the bottom of said hopper, to convey material to the lower end of said elevator-trunk, a powershaft geared to said feed-worm, a pulley on said power-shaft, and an endless belt connecting said pulley andthe pulley on said pivotal shaft, substantially as described.

2. In combination with a truck having a receiving-hopper, and standards which risc from the sides of said truck, beyond and above the discharge end of the hopper, an elevatortrunk having a pivotal shaft at a point inter mediate ol the ends of said elevator-trunk and journaled in bearings on said standards, one end of said trunk when lowered communicating with the discharge end of said hopper, and an endless traveling elevating mechanism in said trunk, said elevating mechanism being driven by said pivotal shaft, a feedworm in said hopper to convey material therefrom to the lower end of said elevator-trunk, a power-shaft, and connections between the same and said feed-worm and pivotal driving-shaft, substantially as described.

3. In combination with a truck having side bars, a receiving-hopper thereon, and standards which rise from said side bars above and beyond the discharge end of the hopper, an elevator-trunk pivotally mounted at a point intermediate of its ends, between said standards, one end of said trunk, When lowered, being adapted to communicate with the discharge end of the hopper and to swing between said side bars of said truck, and a locking-bar, to secure said trunk in operative position, substantially as described.

4. In combination with a truck having a receiving-hopper, and standards which rise from the sides of said truck, beyond and above the discharge end of the hopper, an elevatortrunk having a pivotal shaft at a point intermediate of the ends of said elevator-trunk and journaled in bearings on said standards, one end of said trunk when lowered communicating with the discharge end of said hopper, and an endless traveling elevating mechanism in said trunk, said elevating mechanism being d riven by said pivotal shaft, a feed mechanism in said hopper, and connections between said feed mechanism and the pivot-a1 power-shaft of said elevator, substantially as described.

In testimony that I claim the foregoing as lOO
