The machine'shou u coinprisesfln part, an housing 14, which is s rforuiecl into a hopper wadiqib receive the grain'straw. Atoothed. journaled tra nsyersely cylinder 17 is through the hopper 16, and a toothed con cave-plate 18 is mounted under-the cylinder to j c'o-act therewith in breaking up and whipping the grain straws and heads. A partial partition 19 dependsf'rom the upper wall 20 of the casing;
A shaker 22,]shown separately Fig.2,
is mounted mov'ably in the casing 14, andis' d by pivoted hangers 23 which '0 revoi he i vmg at shaker v26;, shown, separately? in H 'ikewise xnountd "inrearii ard p Patented Apr. 25, 1916. Application filedAugust 9,1912. Serial No.714,170.
14 in front of cylinder 17 to prevent the straw from being so A the casino 14:, in'iniediately below the shaker 5252. and is hnn to said casin by nroted H g l hangers all. For impartnip: to the shakers and .26 o foreaml-aft vibratory movement, a crank-shalt it-l 1s Jourualed trans-- versely through the front portion of the frame lilyaml connecting-rmls 2 3 and 30, respectively, extend from the cranks of said shaft and pirotally attached to said shakers. The shaft E38 is driven by any suitable means, preferably that well known in the art.
Within the rear portion of thc casino, bl,
which receives the grain and othcr matter that pa. down through the opcn portion of the rear or lOWUl' shaker 2b, and an airfan all) providml to cause a more or less forcible blast of air rcaruwn'dly through said riddle-box. i 1
Upon delivery or the grain and other mat ter onto the screen 3!), ti 5 air draft upward through said screen from the air-loin l0 resists the primipitation of a part of the lighter mat or through tho screen, the grain and portions of the heavierlnatter lallino through the screen and toward and upon the fi'n'nal'rlly inclined bottom 4- of the quired, the (.lclivcry of the matter riddle-ho); through the l i blast; The separated grain, bring the heavier matter passing; through the riddle-hon, misses torn-11rd downthc inclined bottom -11 to final dclivery from the machine through a llltiklillly descending trougl'l formed in the lower front corner o'l? said riddlcdnnc. While such grain as has not been entirely freed fron'i or is ciunrhtby the lighter nmtter is driven rcarwm dly up the inclined bottom ill and into a lateral delivery troutrl'i l3 jwlormcd across the lower rear corner ofsaitl riddlebox. The grain and matter that ejected from the rear of the riddle-boxby the air draft is carried upward andfforward on the outside of the casing" 14 by an elevator H, to be again delivered into the casing ll onto the first or upper shaker fora-c :Witation.
Since, in. the threshingot Knfirj corn, for which this invention is primarily designed, only breaking or whipping, operation of tho cylinder 17 and ctmcavcplates 18 re: by the elevator 44; into the casing 14 is made rear- War'dly of said cylinder, and, in fact, rearward into position to deliver ward of the heater 2L as shown, a stopboard as being provided and depending from the top 20 of said casing 14 to prevent the incoming matter from the elevatorspout l6 being unduly fanned from its normal course by said heater.
The construction and operation of the parts thus described does not differ materially 'from those found in other machines of this class, except in the location of the point at which the elevator l-l, delivers its c0ntents into the casing '14 but they do 00-1101; with the newly constructed and arranged parts presently to be destivri'herl in attaining the objects of the invention.
In the improved arrangement and c struction of parts, half ll" of the first or upper shaker 522 is disposed horizontally, but the rear half 48 is inclined upward at a small angle as it extends to the rear end of the machine. This upward inclination of the rear half l8 of the shaker has the etl'ect of partially rctarding the progress ofthe, straw, thereby allowing more time for a more complete separation of the grain therefrom. The inclination of the rear hall 48 of the shalfer 22, however, is not such, with reference to the top 20 of the casing- 14, as will ordinarily pern'iit a congestion of the straw bulk, which, when congestion obtains in devices of this character, finally renders such dcvices inoperative.
best shown in Fig, -l approximately the front two-fifths o1" thc shaker is provided with a lmttorn al which extends rcarits contents into the shaker P36, in further completing the construction of the shaker 22, a, series of parallel ribs 50, are located tran verselywith respect thereto, the ends of said ribs resting upon and being secured to the side pieces 51. of said shaker. 'ln crosssection, each rib no is smbstantially onequarter oi the area of a c] role, as best shown in Fig. 12, one face if! of each rib lying upon the upper edges :13 of the sidepiecc-s 51 while the other face 54 is disposed rearward and perpendicular to said lower face The straw, as it comes from the cylinder 17, drops upon the ribs 50, and, under the influence of the vibratory movement given to the shaker 22, is worked gradually rearward and thoroughly agitated to remote the grain.
-Tn mierationpthe ribs, as arranged, have tho effect of rcarwardly inclined teeth, moving the straw gradually rear ard as stated; but, on account of the cylindrical surface 55 of each rib, the short portions of the broken straws are given a nnn'emcnt not produced by other nmchlnes, with the result that a nun-c complete separation of the seed is effected. y y In actual practnee, the shorter pieces of straw, during their travelover the rlbs, and
approximately the front by reason of the movement of the bulk of straws are tilted rearward, and over the corner 56 of each rib, when they will be allowed to pass on with the bulk .and
thereby prevent temporary retention of pertions of the bulk which would increase congestion if the shorter pieces remained projecting upward from the ribs. This han' dling of the straw retards its passage through the machine suiticiently to allow a full separation of all grain. and the cylindrical surface of the ribs otters a mmnnum retard of the movement of the grain down through the shaker 22.
In Fig. 13 'an optional form of rib is shown, the lines 57 indicating the rear faces 54 previously described. In this optional form of rib, a surface 58, in a horizontal plane, tangent to the curved surface these surfaces 58, when used, having the effect of allowing the straw to remain longer on the. shaker before its final delivery from the rear of the machine. All the matter passing through the ribs 50 of the uppershaker 22 is delivered onto the second shaker 26 for further treatment, the bulk of the straw passing off the rear end of the upper shaker and out of the machine. i
The floor 59 of the front portion of the lower shaker 26 has its, surface formed into transverse rearwardly inclined teeth 60,
'- adapted to urge the matter rearward as the shaker vibrates, but the rear, or remaining portion of said shaker is provided with a extends rearward from the line 57 bottom screen (51 better shown in Figs. 7 to 8), this screen being directly above the riddlebox 3'1. The object of'this screen 61 is to permit the spherical Kafir corn seed, which is heavier thanthe chaff and other matter, to readily run down through openings therein in streams into the riddle-box 31,- and in the attainment of this objecta screen: for that purpose may be made with a suitable form of delivery troughs. In the present instance, however, in forming this screen 61, a blank of sheet metal 62 is cut or slitted on lines (33 transversely of the screen, the portion 64 of the metal immediately in front-of each slit being pressed upward and a portion 65 immediately in the rear being pressed downward. In thus slitting and shaping the metal, a series of small forwardly-descending delivery troughs 66 are provided, with the result that the spherical Kafir corn seed will run down through said troughs into the riddle-box. The trash that follows down through the screen 61 with the grain is caught and blown rearward by air which passes up through the riddle screen 39 from the fan 10.
Having thus described the invention, I claim A threshing machine comprising in combination with means for introducing the grain thereto ofa single upper screen' for separating the grain and chaff from the straw. and means for separating the grain from the chad. said upper screen havi a. reciprogatory movement and exten mg from a point immediately below ducing'means to-a point in the rear of the .cha-fi' separating means, the rear portion of said upper screen being inclined upwardly at a slight angle. and comprising transverse bars, the forward surface of which is cylin 85 drical.
