BURRELL CANNON, OF EGLADEWATER, TEXAS.
MACHINE FOR CLEANING SEED-COTTON.
SPECIFICATION forming part of Letters Patent No. 495,392, dated April 1 1, 1893. Application filed June 9, 1892. Serial No. 436,107. (No model.)
To all whom it may concern.-
Be it known that I, BURRELL CANNON, a citizen of the United States, and a resident of Gladewater, in the county of Gregg and State of Texas, have invented certain new and useful Improvements in Machines for Cleaning Seed-Cotton, &c.; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.
Figure 1 of the drawings is a side elevation of a machine embodying myinvention. Fig. 2 is an end view thereof. Fig. 3 is a vertical longitudinal section taken on line 3 y. Fig. 2, and Fig. 4 is a vertical transverse section taken on line 00 m. Fig. 1.
This invention has relation to certain new and useful improvements in machines for cleaning and transferring seed cotton, and it consists in the novel construction and combination of parts, all as hereinafter specified. In so far as 1 am aware, the-exhaust fans commonly in use in ginneries are employed for the purpose of transferring or elevating seed cotton to the gins, and are unprovided with any means whereby dust, dirt, or other extraneous matter present in the seed cotton, is removed by their operation, separate machines being employed for this purpose. These cleaning machines are expensive, requiring additional power for their operation, and the services of attendants.
The object of this invention is to provide an exhaust fan of this character with means whereby as the cotton is forced through it, the same operation will also suffice to remove therefrom the extraneous matter present therein, without the requirement of additional power or attendance.
In the accompanying drawings, the letter A designates a fan case of general cylindric form, provided at its lower front portion with an extension B, through which is the cotton discharge passage B.
C designates the fan wheel within said casing, and carried by a horizontal shaft D. Lo-
cated around the fan wheel inside the casing, is a cylindric screen E, of comparatively fine mesh wire cloth or perforated metal. This screen is held in place by annular cleats a bolted to the inside of the fan case, which clamp its edges between themselves and the sides of said case. Said screen extends entirely around the fan, with the exception of an interval at F, communicating with the discharge passage B'. At this point, the lower edge of the screen is extended horizontally to the mouth of the discharge, as shown at F, said extension being transversely corrugated, for the purpose presently described. The screen is also placed slightly eccentric with relation to the shaft of the fan wheel, so that while the blades of the fan at the upper forward portion of the case are in close proximity to the screen, those in the lower forward portion are separated from said screen by a greater interval. The shaft D is also eccentric with relation to the circular portion of the case, so that a gradually tapering chamber G is formed between the screen and the case, said chamber being widest at its discharge end, at g.
H is the opening around one end of the fan shaft, through which the cotton enters the case. The revolving fan blades beat the cotton against the screen, breaking up and knocking out the dirt, dust, and other extraneous matter therein, which falls through said screen. Sufficient air will also be forced through the screen to drive such matter'along the chamber G to the discharge where it may be conveyed by boxes or spouts to any suitable point. The corrugations in the horizontal extension F serve to check the particles of matter which might be blown out with the cotton and permits them to fall through the screen. The cotton is driven out through the discharge B, and through tubing or box spouts (not shown) to the gins or storage rooms in the usual manner.
P is a valve or damper located in the dirt discharge, so that the blast therein may be regulated. Said valve or damper is operated by means of a rod or lever P, held in a catch or rack 10.
Having described this invention, what I claim, and desire to secure by Letters Patent, said screen and case, and a regulating valve isat the discharge of said chamber, said case In a combined exhaust fan and cotton cleanhaving a feed opening in one end around the er, the cylindrical case, its forward lower exfan shaft, substantially as specified. 5 tension forming a cotton discharge, an exhaust In testimony whereof I affix my signature in I 5 fan in said chamber, a perforated screen presence of two witnesses.
