GRAIN-SEPARATOR.

' SPECIFICATION forming part of Letters `Zliatent No,` 530,280, dated December 4, 1894.

Application led June 15,1834. VSerial No. 5141674- (NO mOdBL) To all `whom, it may concern: Be it known that I, PETER R. LANIER, a citizen of the United States, residing at Jackson Hill, in the county of Davidson and State of North Carolina, have invented a new and useful Grain-Separator, of which the following is a specification. l

Thisinvention relates to grain separators; and it has for its object to effect certain improvements in machines of this character that are especially designed for subjecting wheat to a separating action for the purpose of separating chaff and other light filth or dirt from the same and thereby to provide means for separatin g and cleaning wheat into v the best possible marketable' grades.

To this end the main and primary object l of the present invention is to construct a vention is better understood, the same con- 2 5` sists in the novel construction, combination, and arrangement of parts hereinafter more fully described, illustrated, and claimed.

In the accompanying drawings :Figure l is a side elevation of a grain separator constructed in accordance with this invention. Fig. 2 is a central vertical longitudinal sectional view thereof. Fig. 3 is a transverse sectional View on the line :cof Fig. 2. Fig. 4 is a similar view on the line y-y of Fig-2.

Referring to the accompanying drawings, 1 designates a suitable supporting frame or stand in which is mounted the separator cas-` ing 2, that is constructed in substantially the same manner as the casings of similar machines and is provided with the bottom imperforate inclined grain board 3, that extends from end to end of the casing to provide for directing the several separations to the proper point of discharge, and in the present invention the said inclined bottom grain board 3, has arranged thereover near its lower rear end the transverse partition board 4, that forms with the rear end'or side of the casing and the rear lower end of the grain board, a grain pocket `5, that is adapted to receive one of the separations of the grain, and the said grain pocket 5, has communicating therewith the rear discharge opening 6, that may be covered and uncovered by the pivoted gate or door 7 and serves to discharge the grain from the pocket-5, into any suitable receptacle placed at the rear end of the machine.

Immediately in front of the partition board 4, the bottom grainboard 3, is provided with the-bottom discharge opening 8, that is cov- `ered and uncovered by the pivoted gate or door 9, and serves to direct the separat-ions that are directed downwardly over the grain board into any suitable receptacle that is placed under the machine below the said opening 8.

Above the plane of the bottom grain board' "2, by the oppositely arranged exterior keeper plates 10a, that are suitably fastened on the outside of the casing, and serve as keepers to properly retain the shoe in position within the slots 10. The sideK guide slots 10, in the opposite casing sides are arranged at an inclination toward the front end of the casing in order to dispose the reciprocating shoe 1l, at the proper inclination so that the Agrain will discharge over the lower open end of the shoe into the grain pocket 5, the lower end 0f said shoe being arranged to reciprocate directly over the said pocket in order to discharge thereinto.

t The separating shoe l1 essentially comprises a' rectangular frame having an open bottom and side strips l2, that loosely register in the side slots l0, and at opposite inner sides of the frame comprising the shoe are arranged the longitudinaly guides or ways 13, which removably receive the opposite side edges of the separating screen or sieve '14, which is`of a suitable mesh in order to effect the necessary separation of the grain, and as the shoe reciprocates certain portions of the grain pass through the screen or sieve onto the bottom grain board and are dischargedthrough the bottom discharge opening 8, while the larger portions of the grain that will not pass through l the screen or sieve are discharged out of the open lower end thereof into the pocket 5, as noted.

The reciprocating separating shoe 11, has secured thereto near its upper high end, the transverse connecting bar 15 to which is loosely con-nected 'one end of the operating pitman 16, the other end of which is loosely connected to the crank 17, formed centrally on the transverse crank shaft 18.

The transverse crank shaft 18,is journaled at opposite sides of the casing in the bearing boXes 19, and has mounted on one extremity thereof the pulley 20, against the upper side of which bears the drive belt 21, passing at one end around the drive wheel or pulley 22, journaled at one side of the casing on the stub shaft 23, and havinga crank handle 24, to provide for turning the drive wheel or pulley by hand in order to communicate motion to the working parts of the machine.

The separator casing 2, is provided at the rear upper corner thereof with the circular fan casing 25, in which is arranged to rotate an ordinary blast fan 26, that is mounted fast on the transverse fan shaft 27, journaled in suitable bearings 28, at opposite ends of the fan casing and carrying on one end the pulley 29, over which passes one end of the belt 21, which provides means for transmitting motion to the rotary blast fan 26. The circular fan casing 25, has the upper and lower sides thereof convergently extended within the separator casing as at 30, to form a contracted blast opening 31, that is located within the casing at a point intermediate of its'ends and directs the blast toward the front open end of the casing, and the upper of said convergent-ly disposed extensions of the fan casing forms an inclined feed board, the upper end of which is disposed directly under the bottom feed opening 31a, of the feed hopper 32, that is supported on top of the separator casing and is provided with flared sides and the single opening 31a, formed transversely in one bottom corner thereof to provide for evenly distributing the grain to be separated onto the upper end of the inclined feed board arranged thereunder.

The grain that falls onto the inclined feed board under the hopper passes directly over and in front of the contracted blast opening 31, and is subjected to the separating action of the blast of air at this point, and the heavier grain falls from the said feed board onto the short cant board 33, secured transversely within the casing below the plane of the contracted blast opening 31, and at a point slightly beyond the lower front end of the board 33, is transversely arranged a deflecting board 34, disposed at substantially right angles to the board 33, and serving to direct a the grain that runs over the said board 33,

Arranged within the front end of the separator casing 2, and in the plane above the short cant board 33, are the opposite inclined guide grooves or ways 35, that adjustably receive the opposite side edges of the inclined grain dividing board 36. The inclined grain dividing board 36, is provided with an inner beveled end 37, that is disposed above the cant board 33, and is adapted to be adjusted to and from the contracted blast opening 3l in order to catch thereon the light puffy grains that are too large to pass through the screen or` sieve, and such particles of grain are directed by the inclined dividingboard 36, beyond the upper end of the reciprocating separating shoe and onto the upper end of the bottom inclined grain board 3, over which the grain is directed downwardly under the shoe to the bottom discharge opening 8.

By reason of the relative disposition of the s grain dividing board and the contracted blast opening of the fan casing, the blast will be contracted to a sufficient force to provide for the separation just noted, and, by adjusting said board7 more or less of the large light grain may be collected and saved for seed purposes if desired.

The front end of the casing 2, is open in order to allow the chaff and other light filth to be blown out of the machine beyond the grain dividing board 36, and in front of the said grain dividing board the front ends of the opposite sides of the casing are provided with the inner vertical side grooves 38, that are adapted to removably receive the front end board 39, which serves to prevent the separations that pass over the board 36, from running out at the front end of the casing, and at the same time permit of convenient access to the front end of the casing for the purpose of adjusting the board 36 and other parts of the machine.

From the above it is thought that the construction, operation and many advantages of the hereinedescribed separator machine will be readily apparent to those skilled in theart, and it will be understood that changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described the invention, what is claimed, and desired to be secured by Letters Patent, is-` 1. In a grain separator, the combination of the separator casing having an imperforate inclined bottom grain board provided with a bottom discharge opening and a separate grain pocket at the lower rear end of said grain discharge opening, an inclinedseparat ing shoe carrying a screen or sieve and supported to reciprocate above the grain board with its lower open end working over said grain pocket,the fan casing having upper and lower side extensions forwardly converged within the separator casing to form a contracted blast opening and the upper of which l'OO side extensions forms an inclined feed board, the hopper arranged above said inclined feed board, the rotary fan arranged Within the fan casing, a short cant board arranged below said blast opening and disposed over the upper end of said separating shoe, a deiiecting board disposed slightly beyond the lower end of the cant board, and a grain dividing board arranged above the cant board above the blast openingand declining to a point above the upper end of said imperforate bottom grain board, substantially as set forth.
