SPECIFICATION forming part of LettersPatent No. 277,512, dated May 15, 1883.

n Application tiled November 22, 1881. (No model.)

To all whom it may concern:

Be it' known that I, JOHN ItUMELY, ot' La. lorte, La Porte county, State ot' Indiana, have invented certain new and useful Improvements in Thrashing-Machines, of which the following is a specification.

'Ihis invention relates to tne separating devices in that class ot `tl "ashing machines known as vibrators In this class ofthrashing-machines the grain is separated from the straw by what is commonly known as a vibrating separator, l upon which the straw and grain are delivered as they come from the cylinder by sonic intermediate carrying mechanism. As this vibrating' separator necessarily occupies a nearly-horizontal position in the machine, and as the straw and grain are delivered to it together', considerable dilliculty has heretofore been experienced from portions 2O ofthe grain being carried or blown through the machine with vthe straw, owing` in a great measure to the vibrating separator being located directly in the air-current produced by the cylinder.

rIhe invention isdesigned to eil'ect a inore thorough separation of the grain from the straw than has been heretofore accomplished; and it consists in the novel arrangement and construction ot' the devices, as hereinafter fully set forth-that is to say, the invention consists in an impervious inclined endlessapron carrier located between the cylinder and the vibrating separator, and extended above the latter, so as to protect it from the blast ot1 5 the cylinder and provide a protected air-space behind the carrier, through which the grain and straw may fall onto thevibrating separator when delivered from the carrier, and thus allow the grain by its greater gravity to become 4o partially separated from the straw and chat't' before reaching the vibrating separator. l also provide an open beater at the top of the carrier, adapted to carry the straw over it and to allon7 the grain to fall through it upon the nearest part ot' the vibrating separator, while the straw or" course is carried somewhat farther. I arrange the vibrating separator about twenty inches below the top ot' the inclined carrier, so as to allow about that space for the 5o gravitation separation of the grain and straw belbre they reach the vibrating separator; but ot' course it will be understood that this distance maybe varied within reasonable limits without departing from the essential feature of my invention.

The accompanying drawings show at Figure l a longitudinal vertical section of a thrasher having my present improvements embodied in its construction, and at Figs. 2 and 3 en larged details ot' the upper beater'. y

The same letters of reference indicate the same or corresponding` parts wherever they appear in the drawings.

In said drawings, Arepresents the cylinder; B, the beater in the rear thereof; C, the endless apron; l), the upper beater at the head ofthe apron, It, the4 vibrating separator, having notched vertical partitions e, a )ilartially-close and partially-perforated iloor, e e2, and two or more series ot vibrating rods, e3; F, the vibrating riddle, and G the fan.

As indicated in the drawings, the endless apron extends some distance above the plane in which the incoming material issues from the cylinder and its accompanying beater, so that the material is not blown directly through the machine by the draft created by the cylinder. y

The upper beater, D, is constructed of ra dial metal arms d, ljnet'erably four in number, at each end, and slats d', extending from the arms at one end to the corresponding arms at the other end, all being` mounted upon a shaft, d?, which is actuated in any suitable manner torevolve in the direction indicated in the drawings, so the current of the feed will pass over it as an overs'hot wheel. By this oonstruction ot' the beaten-viz., the open-frame feature thereofgreat ci'liciency in separating is atta-ined, caused in part, at least, as I believe, by the opportunity which given the grain to fall through the beater instead ot' riding over it, as it would be compelled to do it' the beater were constructed solid or close in the usual manner. From this beater the straw or grain drops or falls upon the sepa rator. The latter is arranged at a considera` ble distance below` the beater-some twenty inches or over-in order to give time for further separation, my theory being that the IOO grain, which is proportionately` more heavy than the straw, will fall more quickly than the latter if an opportunity like that allowed by this arrangement is given. The space wherein this gravitating separation occursl is protected from air-currents, as will be noticed, that created by the thrashing-cylinder passing over it, and that from the fan heingeX- cluded by the close portion of the floor of the vibrating separator. These features I have found by actual use very heneticial in the operation ofthe machine, tending as they do to prevent loss of grain through imperfect separation.

I claim-,-

In a thrashing-machine, the combination of the cylinder and the vibrating separator, with au inclined endless-apron carrier located between said cylinder and separator, and eX- tended above the latter, substantially as dezo scribed, and an open beater at the top of said carrier adapted to carry the straw over it and permit grain to fall through it, whereby the grain and straw are partially separated before they reach the vibrating separator as they fall 25 through the protected space behind said carrier, substantially as spectied.

JOHN RUMELY.
