GRAIN-ELEVATOR FOR THRESHING-MACHINES.

SPECIFICATION forming part of Letters Patent N 0. 649,992, dated May 22, 1900.

Application filed April 7, 1897. Serial No. 631,171. (No model.)

To all whom it may concern.-

Be it known that we, DAVID S. LEE and FRANK O. STUOKEL, citizens of the United States, residing at Peoria, in the county of Peoria and State of Illinois, have invented certain new and useful Improvements in Grain- Elevators for Threshing-Machines; and we do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to grain-elevators for threshing-machines, and has for its object to provide a construction to facilitate in delivering the grain as it leaves the machine to a considerable height above it, from which point it may deliver the grain on either side of the machine into waiting receptacles-as, for instance, wagons, bins, &c.and which may be folded to occupy verylittle space upon the machine when not in use and for detaching the delivery-spout connectedwith the elevator, if desired. 7

The particular features of the invention consist in the mounting of the elevator on top of the machine and providing in connection therewith a conveyer and receptacle containing it adapted to receive the grain from an elevator leading up to said receptacle or from the weighing-hopper.

The elevator proper herein shown is the same in construction as that disclosed in the patent to Stacey B. I-Iart, issued April 30, 1889, and numbered 02,522. Likewise the weigher shown in Figure 1 of the drawings is like that disclosed in patent to Stacey B. Hart, issued February 4, 1890, and numbered 420,798, and we do not make any claim on these constructions, but merely show the weighing apparatus to illustrate our manner of receiving grain therefrom, and the elevator is merely an auxiliary or detached elevator from the main one.

That our invention may be morefully. understood, reference is had to the accompanying drawings, in which 7 Fig. 1 is a sideelevation of a part of a grain separator or thresher with our improved grain-elevator attached thereto. Fig. 2 is a longitudinal section showing a spiral conveyer mounted in a receptacle which connects with and leads into the elevator.- Fig. 3 1s a plan view of the coupling between the hood of the elevator and the adjustable swinging spout. Fig. 4 is an elevation of the coupling, showing a portion of the hood. Fig. 5 is a vertical section through the coupling; and Fig. 6 is also a vertical sect-ion of the coupling, but shows inaddition thereto the lower portion of the hood with the flange in connection therewith.

In the drawings, A is a threshing-machine or grain-separator.

B is an elevator adapted to deliver grain into the weigher-hopper G, the said weigherhopper and weighing mechanism being preferably carried at a point on top of the 1113-. chine and at a height convenient to be reached leads into the elevator D, at the lower or re ceiving end thereof.

E is the lower portion of the receptacle and is preferably made of cast metal and so formed as to provide the journal-bearing e for the shaft G, upon which is fixed the beltwheel II, and also to form the circular extension F, which leads into the elevator. The top portion E of the receptacle is open at the top and fits down upon the lower section.

I is a spiral conveyer, which may be made in sections and properly fixed on the shaft G. The said conveyer bears down in close proximity to the bottom of section E of the receptacle, and this portion of the receptacle is shaped to conform with the general circular shape of the conveyer. The shaft G, which supports the belt-wheel and the spiral conveyer, is adapted to be driven from the saidbelt-wheel H, which will cause the oonveyer to be operated for the purpose of conveying the grain deposited in the receptacle into the lower or receiving end of the elevator.

ICO

G is a shaft in line with and butting up against shaft G and is suitably journaled in thestandardJ at one end, and the other end thereof is carried in the sleeve portion of one a of the sections of the spiral conveyer, and the sleeve and shaft are] secured together by' means of a set-screw or in any other suitable manner, and by means of this connection the said shaft is turned with shaft K is the hub of. the wheelthat carries the chain in the elevator-tube and is fixed upon the standards L L, supported upon rod M and having an adjustable connection with the re-- ceptacle E. We have described a-nd shown a spiral conveyor and also shown and described the detail construction of the same and the manner of mounting and connecting the same with the elevator D; but we may use any kind of conveyer that will perform the function of conveying the grain from the receptacle into the lower or receiving endof the elevator. The elevator D is adapted to be raised and lowered, and to facilitate this adjustment the circular flanges N N- are provided, the flange N engaging the'cap O, which is journaled on shaft G, and the flange Nis supported upon the extension F from the recepta'cle E and is adapted to turn thereon 1 l and the cap 0 to turn as theelevator is raised or' lowered. By means of this manner of mounting the elevator in connection with the conveyer-receptacle we are able to lower the elevator upon the top of the separatoror upon a suitable support adapted to receive and-secure it when it is not in use, and we accomplish this without disengaging the elevator from the conveyerreceptacle and without disengaging any parts except the supportingbar P, which is provided to maintain it in-an elevated position, and we do this simplyby removing the bolt connection between the bar and'the elevator. a

By means of the provision of the conveyer and the receptacle containing it used in connection with the auxiliary elevator we are able to weigh the grainat a convenient point at or near the top of the separator, as and in the manner shown in the drawings, which;

enables us to mount the said weigher in a fixed and firm position, thus obviating the necessity of removing the weigh'er or-folding it up when not in use and'for transportation, and also obviating excessive vibration which would attend the operation of the separator,

which would affect the weighing apparatus if it. were mounted at considerable height above it, and by using the auxiliary elevator D we are able to elevate the grain to the high 1 point necessary in order to spout it into wagons, blHS, or other waiting receptacles at either side ofthe machine and at varying;disfances there from, and by using the receivingreceptacle E, containing a conveyeradap'ted.

to convey the grain into the lower 'or receiving end of elevator D, we obviate any danger of clogging or overloading the elevator, as the conveyer is adapted to deliver the grain thereto in such quantities assaid elevator is adapted to handle conveniently, the receivin g-receptacle E beingmade of sufiicient size to accommodate accumulation above the normal quantity, so that there is no chance for packing for clogging therein.

1 At the upper portion of the elevator andi1 connection with the plate Q on the mouth 0 x the hood wehave provided an intermediate coupling R between the said plate and the spout S. The said coupling is formed of two main sections, which are bolted together in the manner shown, and the hinge secti'on T, which said section is providedwi-th the groove 25, which matches with the groove t"in-th-e upper edge of the coupling R,'whieh forms a continuous circular groove adapted to engage a flange on the lower end of plateQand is adapted to turn thereon, thus enabling the spout connected with the coupling to be turned from one side of the machine to the other at will. The spout S is adapted to be pivoted to the coupling, as at r, and to be made considerably larger than thesaid coupling R in order to allow "said spout to be raised and lowered-.- By means of the'hingesection T being made to form a part of the connection of the coupling with plate Q by disengaging one end of the hinge-section we are able to swing it out of engagement with the flange on plate Q and then to remove the coupling and the spout connected therewith,

thus providing a simple means of attaching and detaching the spout from-the elevator for convenience in folding up for transportation.

7 Having thus fu-l'ly described-ourinvention,

what we claim, anddesire tosecure by Lettersiliary elevator, means for carrying the grain received in said receptacle to the auxiliary elevator, a discharge-chute suitably carried in connection with the auxiliary elevator as to permitit to be raised or lowered'and adapted to delivergrain at either side of the machine, all substantial] y as and for the purpose described.

. 2. The combination with a threshing-machine, of the main elevator B, extending from the bottom of the machine to the topof the same, theintermediate receptacle E, the spiral conveyer I, suitably carried therein and adapted to receive grain from the main elevator B, of the auxiliary elevator D, connect led with the receptacle E, and receiving grain therefrom, discharge-chute S, suitably car- {to said coupling R, the hinged section T,

ried in connection with the auxiliary elevator as to permit it to be raised or lowered and adapted to deliver grain at either side of the machine, all substantially as and for the purpose described.

3. In a grain-elevator, the combination with the main elevator B, of the intermediate receptacle E, a suitable conveyor carried therein, the auxiliary elevator D, suitably carried in connection with the receptacle E, the plate Q, the intermediate coupling R, between the said plate and the spout S, which is pivoted adapted in conjunction with the main coup I 5 ling to engage a flange on plate Q, whereby when the hinge-section disengages the flange on the plate, the coupling and the spout may be detached from the conveyor.

In testimony whereof we affix our signa- 2o tures in presence of two witnesses.
