SFECIFICATION formingpart of Letters Patent No. 716,431, dated December 23, 1902- Applioation filed May 13, 1901. Serial No. 59.954. (No modeLl 1'0 all w/wm, it may concern:
Be it known that I, PHILIP KESSELRING, Jr. a citizen of the United States, residing at Tripp, in the county of Hutchinson and State of South Dakota, haveinvented certain new and useful Improvements in Fanning-Mills; 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 had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.
This invention relates to improvements in fanning-mills designed primarily forthe sepa ration of chaff and other screenings from grain and the like.
An object of the invention is to provide a mill with ahopper and an inclined plate therebeneath adapted to be used either alone or in connection with the usual screen to provide an extensive runway upon which the grain discharged from the hopper may slideand be separated by a blast of air thereover.
A further object of the invention is to provide a screen provided at one end with a sheet-metal or other protecting device upon which the grain to be screened may drop, whereby a serious objection heretofore existing in the art is overoome-t'. 6., the clogging of the meshes of the screen incident to the rapid fall of grain concentrated at this particular portion of the screen.
The invention also embraces a novel means for giving a slight lateral vibration to the supporting portion of the machine in which the inclined plate to which reference has been made above and the screen superposed thereupon, if any be employed, are located to shake the material on the screen and cause the same to travel down the inclined plate.
The invention still further contemplates the providing of extensions for the end board or plate of the machine for the purpose of preventing the cleaned grain from piling around the corners of the machine, so as to again become intercommingled with the screenings, or vice versa.
Improved details in the arrangement and construction of the several parts of the machine will be apparent from the detailed description hereinafter when taken in connection With the accompanying drawings, forming part hereof, and the appended claims.
In the said drawings, Figure 1 is a side elevation of the complete machine. Fig. 2 is a longitudinal sectional view thereof. Fig. 3 is a sectional detail view of the means to vibrate the frame.
Referringmore specifically to the drawings, like reference characters will designate corresponding parts in the several views.
A designates a casing of any suitable and preferred construction. The casing is closed at one end, as at a, and is provided with converging top and bottom Walls a and a respectively, to provide a fan-casing B. Adjacent the rear Wall of the fan-casinga suitable fan 0 is mounted upon a rotatable shaft 0. The desired quantity of air maybe admitted to the fan through the opening 0' in one of the side walls of the casing, the size thereof being controlled by oppositely-disposed shutters 0' C adjustable in an obvious manner. Power is supplied to the fan-shaft by means of a belt I) passing over apulley d at the end thereof and also over a relatively large pulley I), provided with an operating handle or crank D The belt also passes around a third pulley E for purposes to be hereinafter pointed out.
At the end of the machine opposite the fan directly beneath an enlarged opening in the top of the casing is a hopper F, adapted to receive the grain to be screened. The hopper is provided with a discharge-opening 25, controlled by a slidahle valve 6', provided with an elongated stem 1?, passing through an aperture in the end of the casing and provided with a screw-threaded handoperated device 15 Directly beneath the hopper a frame Gr, comprising side walls united by a tie-rod g, and a flexible bottom 9 connected to the said sides and also to a portion of the main frame of the casing, beneath the body thereof, as at g is supported in position to vibrate laterally by swinging links H, pivoted outside the hopper and engaging suitable bearings h on the exterior surface of the Walls g. Supported in any desirable manner in this frame G is an inclined screen I of any style, while located a slight distance therebeneath is a correspondingly-inclined plate J.
This plate J extends outward to a point slightly inward from the end of the machine and is adapted to receive the material from the screen I in a manner to direct the same in a thin layer upon the end of the lowermost screen K. The arrangement above described permits the passage of a blast of air from the fan 0 to pass beneath a deflector j and over the thin layer upon the plate J, so as to blowoff the chaff or lighter particles therefrom as well as from the same material, as it falls from the end of the plate upon the screen K.
From experience it has been found that the continuous fall of material in bulk upon one point of the screen clogs the same, and to overcome this objection I cover the end of the screen with a metallic plate 70, upon which the material may primarily fall and slide therefrom onto the screen K, arranged at such an inclination as to convey the material away from the machine after its final screening. This last-mentioned screen K is also supported between the side Walls g and is adapted to be vibrated with the same. It has also been found that the material after being screened and discharged atthe end of the machine frequently fills so as to fall around the ends of the end board or plate Z, and to overcome this objection wings or extensions L are hinged to the ends of said end plate in a manner to be swung outwardly to constitute continuations of said end plate. The wings are locked in their outer positions by catches Z thereon engaging suitable loops on the corner-posts of the frame of the machine.
The frame G, carrying the screens, is vibrated by means of an axle 00 extending across under the bottom a of the casing, which axle has at each end a crank-wheel E, one of which forms a pulley for the belt D, as above described. Each crank-wheel is connected to the frame G by a pitman M, joined at its end to a strap M, which passes through a bracket (indicated at m) on the side of the frame, within which it is secured in adjusted position by means of a thumb-bolt m. The strap works over an antifriction-roller N, supported in bearing-brackets n on the side of the machine.
.These parts at one end of the axle are clearly shown in Fig. 3 and are duplicated at the other end of the axle, with the pitman having an opposite throw, so as to give the frame a reciprocating motion, as will be understood. It is to be understood that slight changes in the construction and arrangement of the several parts of the machine above described may be made Without in the least departing from the nature and spirit of the invention.
Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is
1. In a fanning-mill, in combination, a casing open at one end and having a fan therein, a hopper above the open end of the casing, a vibratory shoe thereunder containing an inclined screen adapted to receive material from the hopper, a plate under the screen inclined in the same direction and spaced therefrom at both ends forming a blast-passage therebetween, said plate being adapted to receive material from the screen and deliver the same in a sheet, an oppositely-inclined screen below the plate and extending beyond the shoe into the casing, a solid strike-plate on the screen to receive said sheet of material, and a flexible bottom below the last-mentioned screen, joining the shoe to the casing.
2. In combination with a fanning-mill or the like, an end board or plate adapted to separate the screened material from the screenings, and wings or extensions for said end plate, substantially as and for the purpose described.
In testimony whereof I affix my signature in presence of two witnesses.
PHILIP KESSELRING, JR.
