Patented duly 2'9, thi h Application filed may 7, 1913. Serial No. 7863309.
To all whom it may concern:
Be it lmown that 1, JOHN E. GRAPER, a citizen of the United States, residing at Fort Atkinson, county of Jefierson, and
State of Wisconsin, have invented new and useful Improvements in Elevators for Corn Huskers and Shredders, of which the following is a specification.
My invention relates to improvements in elevators for corn huskers and shredders and the like.
The object of my invention. is to provide a more eflicient and durable device for simultaneously separating the shelled corn from the husks and shredded stalks as the same are being elevated from the husking rollers to the pneumatic tubes or other mechanism.
by which the husks are conveyed to the place of discharge.
My invention is further explained by reference to the accompanying drawings, in Which- Figure 1 represents a side view of my elevator as it is used in connection with an ordinary corn husker and shredder, the sides of the corn husker and shredder being broken away, the better to disclose the construction of my improved elevator. Fig. 2 is a plan view and Fig. 3 is a side view of a portion of the elevator removed from the husker and shredder.
Like parts are identified by the same reference numerals throughout the several views.
My elevator comprises, among other things, an endless series of horizontally ar 1, which bars are each support ranged bars ed at their respective ends from an endless chain 2, it being understood that a similar chain to that shown is used at the opposite end of said bars, and these chains 2 each comprise a series of separate links 3. The links 3 are each provided at one end with hooks 4, and between their ends with apertures 5, in which said hooks engage, whereby a plurality of links are adapted to be interlocked together to form said endless chain 2 at' each end of said horizontal bars 1. The several links 3 are provided at their inner sides with pockets 6, for the reception of the ends of said horizontal bars 1, and said bars are retained in said pockets by screws 7, which are inserted through said links into .said bars as shown in Fig. 3. One of the corners 8 of said horizontal bars 1 is removed, whereby the upper surface (reference being had to the upper side of Fig. 3) inchnes downwardly and rearwardly from the front edge 9 of said bars, whereby the corn or other grain, which is being elevated with the husks is free to drop rearwardly and downwardly and pass between the several bars 1 oi the elevator, when such grain descends of its own gravity upon the downwardly inclined plate 10, when the same may be carried away by a conveyer 11 to the side of the machine. the upper edges 12 of said bars are provided with a plurality of pins 13, the pins of one her being preferably arranged to alternate with the pins of the two next adjacent bars above and below, as shown in Fig. 2. Theres ectivc chains 2, together with the series 0' transverse bars and pins, are adapted to be supported at their lower ends from a driving shaft 14 upon a pair of sprocket wheels 15, and at their upper ends from a shaft 16 upon the sprocket wheels 17 when, as said shafts and wheels revolve, the teeth 18, of said sprocket wheels operate in the apertures 5 of said chains. I
I am aware of the fact that sprocket wheels and sprocket chains are not new; also that it is not new to connect chains'together by transverse bars, but invention herein is predicated more especially upon the peculiar construction of said bars, in which one of the corners 8 is removed, leaving the bars substantially triangular in cross-section, while each of said bars is provided with a plurality of vertical pins 13, the pins of one bar being arranged to alter-' nate with the pins of the two next adjacent bars, said bars, being adapted by their peculiar shape, to facilitate the separation of the shelled corn from the husks, while the pins 13 cotiperate with the bars in elevating the husks froin' the lower to the upper end of such conveyer.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
l. In an elevator for corn huskers and shredders, the combination of a pair of endless sprocket chains, a pair of sprocket wheels, located at the respective upper and lower ends of said chains, a shaft for revolubly supporting each pair of sprocket wheels, a series of transverse bars substantially triangular in cross section, means for connecting the respective ends of said bars with said sprocket chains, and a series of ill? Add
- pins connected with and projectilig laterally from each of said bars.
- 2. In an elevator for corn huskers and shredders, the combination of a pair of end"- less sprocket chains, the respective links of said chains being provided with pockets for the reception of transversely arranged bars carried by said chains, a pair of sprocket wheels, located at the respective up er and lower ends of said chains, a shaft or revolubly supporting each pair of sprocket wheels, a series of transverse bars substantially triangular in cross section, having their respective ends located in, the pockets of the links of said chains, each of said bars having its lower outer corner removed to facilitate the passage of shelled corn between them, and a series of pins connected with and projecting laterally from each of said ars.
3. In an elevator for corn huskers and shredders, the combination of a pair of endless sprocket chains, each comprising a series of links, each link being-provided with a pocket for the reception of the end of one of the transversely arranged bars, a pair of sprocket wheels, located at the respective upper and lower ends of said chains, a shaft for revolubly supporting eachpair of sprocket wheels, a series of transverse bars substantially triangular in cross section, having their respective ends located in the kets of the links of said chains, each 0 said bars having its lower outer corner removed to facilitate the passage of shelled corn between them, a series of pins connected with each of said bars, the series of pins of one of said bars being located at intermediate points between the pins of the two next :adjacent bars above and below;
In testimony whereof I aflix my signature in the presence of two witnesses.
