5-. N. SORENSEN DOCKAGE SCREEN FOR THRASH'ING MACHINES med April '2 1925 2 Sheets-Sheet 2 Patented Mar. 20, 1928.
UNITED STATES PATENT GFFICKT SEVEEIN N. SOREN'SEN, OF ST. FAUL, MINNESOTA.
DQCKAG'E FOR THRASHING MAcfiIN-E Application filed April 25, 1925 Serial No. 25,797.
My invention relates to screen or sieve structures of the general character usually designated as dockage screens, especially adapted for use in connectionwith thrashing machines bun-nevertheless, capable of more general use. Generally stated, the invention consists of the novel devices and combinations of devices hereinafter scribed and defined in the claim, In a sense, the present invention is in the nature of an improvement on or modification of the screen or sieve structure disclosed and claimthe sieves- I have found that thisdiificulty maybe overcome in the most effectual way by providing cleaning devices or scrapers operative on the upper as well as the under surface of the screen. One feature of the invention is directed to the arrangement above broadly indicated and to simple and efiicient means for rendering the upper and lower sieve-cleaning devices simultaneously operative.
Other features of the invention will be hereinafter disclosed and particularly pointed out in the claim.
The invention is illustrated in the accompanying drawings, wherein like characters indicate like parts throughout the several views.
Referring to the drawings: Fig. 1 is a verticallongitudinal section taken through the vibratory sieve shoe and associated parts of a thrashing machine, the
said sieve shoe being equipped with my improved dockage screen and cleaning devices;
Fig. 2 is a fragmentary perspective showing a gate board removed from the seive 4 shoe; and v Fig. 8 is a plan view of the vibratory sieve shoe, dockage screen and cooperating cleaning devices.
Of the parts of the thrashing machine, it is only desirable for the purposes of this case to particularly note the framework 4 of the machine casing, the vibratory sieve shoe 5 with inclined bottom deck 6, and the upper or scalping sieve 7 mounted in the shoe in the customary'way. The lower end of the deck 6, as shown, delivers to an auger-equipped transverse trough 9. The shoe 5- carries a T 1 lower inclined deck 10 that delivers toa transverse augenequipped trough 11. The inclined deck 6, rearward of its lower or delivery end, has a transverse dockage discharge passage 12- that is adapted to be -.1;
closed at certain times by a gateacting board 13-, which, when applied, may beheld working position by any suitable means, such as clips or turn-buttons 14 applied to the bot* tom of the deck 6. a
The upper cleaning device, preferably and as shown, is made up of a coarse mesh wire fabric 20 having a marginal frame 21. This wire fabric cleaning device rests loosely on the upper surface of the screen 16 and the transverse upper bar of the frame 21 is connected to metal straps 22, the ends of which are perforated so that the upturned ends 18 of the bars or rods 18 are passed therethrough, Thrust rods or bars 23, at their forwardly extended ends, are perforated and applied around the upturned ends 18 of the bars 18 and the rear ends of said thrust bars are anchored to a relatively fixed part of the machine frame, being, as shown, directly secured to eye-bolts 24, which bolts 2d are applied to angle bars 25, which, in turn, are
bolted to the rear portion of the machine frame 4. The sieve shoe 5 will or may be supported by longitudinal vibratory movements by the usual means employed in thrashing machines and, of course, when the shoe is vibrated, the screen 16 will be carried therewith, and the upper and lower cleaning devices being anchored will be caused to'scrape and clean both the under and upper surface of said screen, thereby ample, French iveed, pigeon grass, rbuck Wheat, barley, cracked and shr veled wheat, 1
Will be passed through said dockage screen and ontothe inclined deck6.
In the operation of the machine, good vWheat and oats,fusually designated as suc- Y cotash Will pass off-from the lower end of thescree-n 16 'and into the trough 9, While the-'dockage dropped onto the inclined deck 6 Will be discharged through the passage 12 and either onto the ground or into a suitable receptaclethat may be provided to revceivelthe same. [The coarse materials, such as chaff, straw and the like, delivered from the loW er-endof the scalping screen 7, will drop onto the deck 10- and be delivered to the trough 11 7 Sometimes, in the operation of the thrashing machine, it may not be desirable to'separate the dockage from the good grain, and
in that event, the board 13 may be used to close the'passage 12 so that the doclrage Will be dischargedoff from the lower end of the deck 6 and into the trough 9, Where it Will berecominingled With the good grain.
The frame 15 of the dockage screen may be secured to the inclined deck 6 of the vibratory shoe Shy screws, bolts, or in any other suitable Way, and need not be removed, when the machine is to be used for the separation of the dockage from the good grain.
What I claim is: r I
The combination With a relatively fixed frame and a Vibratory shoe of a thrashing machine, of a dockage screen applied'to said shoe, a lower cleaning device Working against the under surface of said screen and having extended loars With upturned rear ends, an
upper cleaning device Working on the upper surface of said screen andhaving extended bars anchored to the upturned ends of the bars of said lower cleaning device, and thrust rods applied to the upturnedends of said latter noted oars and anchored tosaid frame, said bars and thrust rod constituting means for causing a relative movement of said cleaning devices in respect to said screen.
In testimony whereof I my signature.
SEVERIN N. SORENSEN.
