UNITED STATES PATENT OFFICE.
ROSW'ELL BEAR-DSLEY, OF ASHBY, MINNESOTA.
THRASHlNG-lVlACHlNE.
JPIECIFICATION forming part of Letters Patent No. 339,841, dated April 13, 1886.
Serial No. 185,149. (No model.)
To all whom it may concern:
Be it known that I, RosWELL BEARDSLEY, a citizen of the United States, residing at Ashby, in the county of Grant and State of Minnesota, have invented certain new and useful Iinprovementsin ThrashingMachines; and
- I do declare the. following to be a full, clear,
and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.
This invention relates to certain new and useful improvements in thrashing-machines, and it has for its object to construct a machine in which the interior parts will be made more readily accessible during the operation for inspection or the removal of obstructions than in other machines of this character as heretofore constructed.
In the accompanying drawings, forming a part of this specification, and on which the same letters of reference indicate the same or corresponding features, Figure 1 is a longitudinal sectional view of my machine, also showing in dotted lines the wheels and connecting-bar for agitating the straw rake or shaker as arranged on the hither side of the machine; and Fig. 2 is a perspective view of the grain-conveyer.
The letter A designates the feed hopper from which the grain is fed to the cylinder B. Below this cylinder is the usual concave, 0, having an upwardly and rearwardly ext-ending portion, D, whereby, as the cylinder revolves, the grain is pushed up to and acted upon by the beater E.
The letter F refers to the rake-frame, the straw-shaker,supported by the crank-shafts G, passing beneath them and journaled in the sides of the thrasher proper. As seen in Fig. 2, these crank-shafts are provided on one side with rigidly-secured pulleys H, connected at points opposite the cranks by a pitman, I, and one of the crank'shafts on the other side is further provided with a pulley, J, which receives its motion from the driving-pulley and transmits it to the crank-shafts, thereby agitating the rake-frame. This frame consists of a series of bars mounted at each end on the crank-shafts equidistantly from each other, and provided with laterally and longitudinally ext-ending rows of teeth K, the purpose of which is to catch hold of the straw and assist it in its movement through the machine.
Pivotally suspended below the rakeframe by means of the bars L is the grain-conveyer M, consisting of the side bars, N, and the corrugated bottom 0, the rear portion of which is provided with a series of rods, P, preferably of metal, which receive the coarser material which is delivered from the conveyer.
Q refers to a crank-shaft which is located in the forward portion of the machine, and is connected with the grain-conveyer by a pitman, R, attached to the bracket S, by means of which the conveyer receives its motion.
T designates a shoe suspended in the frame work of the rearportion of the machine,which delivers its products into the box U, located transversely beneath the machine.
V V refer to pulleys over which travels the usual endless tailings-retnrn elevator, W, and the letterXdesignates the fan located in front of the shoe.
The operation of the machine is as follows: The wheat is introduced into the machine at A, and is by the cylinder and concave pushed up wardl y and rearward] y to the beater E. There it is received upon the rake-frame and thoroughly agitated, the grain falling through the bars constituting the frame upon the reciprocating grain-conveyer beneath, where it is carried by the steps or corrugations toward the rear of the machine, where it falls into the shoe, the fan blowing off the chaif, while the elevator carries off the straw, and the grainis received by the box U.
It is to be observed, that the cranks of the crank-shafts are arranged with their cranks substantially parallel to each other and in a reversely-set position, one crank being up while the other is down, whereby a violent seesawing movement is imparted to the rake frame, and at the same time it will take longer for the grain to reach the rear of the machine, the result of which is to more effectnall y agitate the grain during its passage. It is further to be observed that should the rake-frame or the grain-conveyer become clogged it is only necessary to go to either end of the machine and there insert an ordinary IOC garden rake or similar implement and remove the obstruction, which can he done with little or no loss of time and without stopping the machine. I
Having thus fully described my invention, what I claim as new, and desire to securev by Letters Patent, is-- 1. In a thrashing-machine, the combination of the cylinder, the beater located in the rear of and above the concave,the oppositely-set revolving crank-shafts, the toothed rake-frame mounted thereon, the suspended horizontallyextending grain-conveyel' consisting of side bars and a corrugated fioor and rearwardlyextending rods, and the shoe hung at the rear and beneath the rakeframe and conveyer.
2. In a tln'ashing-machine. the combination, with the cylinder, the concave, and the beater located in the rear of and above-the concave,-
of the rake-frame consisting of slatshaving each a row of teeth, and the revolving crankshafts havingtheir cranks oppositely set, upon which the said rake'frameis mounted.
3. In a thrashing-machine, the combination,
with the revolving crank-shafts having their cranks oppositely set, of a rake-frame-consisting of slats having each a row of teeth mounted upon said shafts, whereby one end of the rakeframe is rising as the other is descending.
In testimony whereof I aflix my signaturein 3o 3 Witnesses:
