EXHAUST-FAN.

Specification of Letters Patent.

Application filed February 14, 1912. Serial No. 677,442.

To all whom it may concern."

Be it known that I, SAMUEL REMBERT, a

citizen of the United States, and a resident of Memphis, in the county of Shelby and State of Tennessee, have invented certain new and useful Improvements in Exhaust-- Fans, of which the following is a specification.

This invention is an improvement in exhaust fans and particularly in that class of such devices illustrated in my former Patent No. 579,081 of March 16, 1897, the present invention seeking to provide a novel construction by which the seed cotton or similar material handled by the fan may be discharged separately from the dust laden air drawn in by the fan, thus enabling the discharge of the seed cotton and of the dust laden air at different points and separately; and the invention consists in certain novel constructions and combinations of parts as will be hereinafter described and claimed.

In the drawing Figure 1 is a sectional plan view of a fan embodying my invention. Fig. 2 is a sectional side elevation thereof.

Fig. 3 is a side elevation, parts being broken.

away and others shown in section.

In the present apparatus I employ a casing A, a fan B, and an inlet C together with a perforated or foraminous guard plate D held to the fan B and revolving therewith, which parts are similar to corresponding parts in my former patent above referred to. By my present invention, however, I divide the outlet E by means of a partition plate F into channels E and E In the operation of the fan, the material flows in the inlet 0, being drawn therein by the operation of the fan and the seed cotton'or other solid material which cannot pass through the perforated plate D passes down through the passage space E being aided in such operation by the movement of the perforated plate, whilethe dust laden air passing through the perforated plate D is discharged at E to the outlet channel E the latter being separated from the channel E by the partitionplate F as before described. This plate- F, it will be noticed from Fig. 1, extends inwardlyinto close proximity at F with the circumference of the fan and the plate is provided with ,a pearward extension F projecting under the In practice the channel E may connect With an off-take pipe E which may pass to the top of the building or other suitable discharge point while the channel F may be prolonged to deliver to a bin or other receptacle.

The invention is simple, facilitates the conveyance of the seed cotton or other malPatented Sept.3,1912.

terial to the desired point and operates to; 4

clean the same and to separate the cleaned material from the dust laden air as will be understood from the foregoing description.-

In operation, it will be noticed that the dust in the air will be drawn against the side of the fan opposite the perforated guard plate so that the dust laden air will be discharged to the outlet channel E? while the seed cotton' or the like will be operated upon by the blast of air from the fan as most clearly shown in Fig. 1 of the drawing. I claim: I '1. An exhaust fan, substantially as herein described, comprising a fan case having'an inlet and an outlet, a fan within the fan case and having on its side next the inlet a perforated or foraminous guard held to' and revolving with the fan and spaced from I the side of the fan case whereby to provide a passage space within the case and extending from the inlet to the outlet and a partition plate approximately parallel with the plane of perforated guard and arranged within the outlet and operating to separate the material discharged from the passage space from the dust laden air, etc discharged from the fan, the partition plate having a rearward extension underlying and conforming to and resting in close proximity to the fan, substantia ly as set forth.

2. An exhaust fan having a fan case provided with an inlet and an outlet, a fan within the case, a perforated guard forming with the fan case a space for material drawn inward by said fan and means dividing the outlet into separate channels laterally side by side for the discharge from said space and directly from the fan, substantially as set forth.

3. An exhaust fan comprising a fan case having an inlet and outlet, a fan in the case, a perforated or foraminous guard plate secured to and revolving with the fan and forming with the fan case a passage space leading from the inlet to the outlet and a partition plate in the outlet and conformin edgewise to the fan and dividing the out et into separate channels laterally side by side, substantially as set forth.

4. An exhaust fan having at one side a perforated or foraminous uard held to and revolving with the fan an a casing inclosing said fan and having an inlet on its side next to the said guard, the casing being also providedwith an outlet and with a partition plate Within the outlet and approximately parallel with the plane of the perfoee-wee is adapted to receive the material checked by the erforated plate and the other the 15 an disc arged directly from the fan, all substantially as and for the purpose set forth.
