BRUSH FOR COTTON GINS Filed Aug. 13, 1929 INVENTORS. mflimalbrbefi' Patented July 1, 1930 stars Afar WILLIAM C. TORBETT, OF WAQO, TEXAS BRUSH non common GliNS Application filed August 13, 1929. SerialNo. 285,551.

This invention relates to a cotton gin brush for use in connection with cotton gin stands. I

AS is well known, all cotton gin-stands from as to 60 inches, depending on the size of the gin stand; this brush is of a cylindrical shape. The brush cylinder has inset insert portions having wooden bars 19 arranged therein. Each'bar carries a row of bristles. These bars are set at intervals around the cylinder and during the operation of the gin stand, the britsles act to sweep the cotton against the saws that [L5 separate the lint from the seed. In wet or damp weather the brush cylinders swell and are shifted out of balance and further the bristles lose their stiffness, the result being that when damp or wet cotton is run into the gin stand it will adhere to the bristles, gomingl such action being termed in this line of manufacture.

The object of a cotton gin brush, in accordance with this invention, is to overcome the disadvantages referred to and to this end the invention aims to provide in a manner as hereinafter set forth a gin brush con' structed of sheet metal and carried by a metallic or wooden head or drum and with the brush set up in a manner to include fans or protrusions as a substitute for the bristles for the purpose of sweeping the cotton against the saws.

A further object of the invention is to provide, in a manner as hereinafter set forth, a metallic cotton gin brush which is not affected by temperature or moisture and free of any attack by rodents, as is the case in brushes now generally employed as the rodents frequently destroy the bristles and oftentimes the sticks, which places the brush entirely out of balance.

Further objects of the invention are to provide, in a manner as hereinafter set forth, a metallic cotton gin brush which is simple in its construction and arrangement, strong, durable, compact, thoroughly efficient in its use, conveniently assembled and comparatively inexpensive to manufacture.

' With the foregoing and other objects in are equipped with a brush ranging'in length view the invention consists of the novel construction, combination and arrangement of parts as hereinafter more specifically described, and illustrated in the accompanying drawings, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which fall within the scope of the claims hereunto appended;

In the drawings wherein like reference characters denote corresponding parts throughout the several views t Figure tie a perspective view of a cotton gin brush in accordance with this invention.

Figure 2 is an end View thereof.

Figure 3 is an end View of a modified form.

The body of the brush, which is of tubular, cylindrical form, can be set up from a single length of sheet metal to provide a hollow cylinder as shown in Figures 1 and 2, or set up from a series of arcuate sections of sheet metal as illustrated in Figure 3. 1

The brush includes a carrier 1 of circular cross section provided at each end with a spindle2. The spindles 2 may be formed from a single shaft which extends axially of the carrier 1 and projects from the ends thereof. The carrier 1 can be formed of any suitable material preferably woodif desired. It is to be understood that the carrier can be constructed in any desirable manner and of any desirable material.

Referring to Figures 1 and 2 the body of the brush is indicated at 3 and is formed from a length of sheet metal, bent in cylindrical form with the lengthwise edges thereof in abutting relation and secured together in any suitable manner.

The body portion 3 is provided with outwardly bent folds to form lengthwise extending, spaced, radially disposed blades, wings, vanes, fans or protuberances 4 of tapered cross section. The blades, wings, vanes, fans or protuberances will be hereinafter termed vanes and are employed for the same purposes as the bristles, that is to say for sweeping the cotton against the saws which separate the lint from the seed.

The vanes correspond in length to the length of the body portion and are formed from inherent parts of the metallic sheet from which the body portion 3 is set up.

Referrin to Figure 3, which illustrates the modifie form of brush, the hollow body portion generally indicated at 5, is of circular cross section and formed from a series of abutting sections 6, of arcuate form in cross section and with each section 6 formed from sheet metal and provided with a plurality of radially disposed vanes 7 of tapered cross section. Preferably each section 6 will be provided with outwardly bent folds to form a pair of spaced vanes. The abutting edges of the sections 6 are to be secured together in any suitable manner.

The body portion 3 or the bod ortion 5 snugly engages the periphery o t e carrier 1 and suitably connected therewith, whereby the carrier and body portion will bodily rotate in unison. Further the body portion of the brush is so secured to the carrier to prevent its shifting circumterentially with res ect to the carrier.

In bot forms shown the radially disposed vanes are equall spaced with respect to each other on the b0 y portion. The vanes 7 are formed of inherent parts of the sheet metal from which the sections 6 are set up.

The vanes are so set up whereby they are formed of two parts, that is to say a leading part and a follower part and with said parts spaced from each other thereby providing for the vanes to have a slight resilient characteristic. The outer ends of the vanes are sharp and uninterrupted from end to end.

It is thought that the many advantages of a metallic cotton gin brush, in accordance with this invention, can be readily understood, and although the preferred embodiment thereof is as illustrated and described, yet it is to be understood that changes in the details of construction can be had which will fall within the scope of the invention as claimed.

What I claim is:

1. A cotton gin brush comprising a onepiece body ofsheet metal consistin of a ollow, cylindrical metallic body portion for snugly enveloping a rotatable carrier therefor, and said body ortion bein formed 7 with outwardly bent olds to provide a plurality of outwardly directed, radially disosed metallic vanes extending from said ody ortion, said vanes in cross section bein o tapered contour and spaced from each 0t or at their inner ends.

2. A cotton gin brush comprising a onepiece body of sheet metal consisting of a ollow, cylindrical metallic body portion for snugly envelo ing a rotatable carrier therefor and sai body ortion bein formed with outwardly bent olds to provide a plurality of outwardly directed, radially disposed metallic vanes, said vanes in cross section being of tapered contour and equally spaced from each other at their inner ends.

3. A cotton gin brush comprising a hollow, cylindrical metallic body portion for snugly enveloping a rotatable carrier therefor, and said body )ortion being formed with outwardly bent olds to provide a plurality of outwardly direct-ed, radially disposed metallic vanes projecting from and merging at their inner ends in said body portions, said vanes in cross section bein of tapered contour and spaced from eaci other at their inner ends.

4. A cotton gin brush comprising a hollow, cylindrical metallic body portion for encom assing a carrier therefor and provided wit outwardly bent folds to form a plurality of spaced, outwardly directed, iiitegral, radially disposed metallic vanes, each of said vanes in cross section being ta ered and formed of a leading part and a fol ower part s aced from each other and further forum with an uninterrupted outer edge, said vanes at their inner ends being spaced from each other.

5. A cotton gin brush comprising a hollow, cylindrical metallic body portion for encompassing a carrier therefor and provided with outwardly bent folds to form a plurality of spaced, outwardly directed, in tegral, radially disposed metallic vanes, each of said vanes in cross section being tapered and formed of a leading part and a follower part spaced from each other and further formed with an uninterrupted outer edge, said vanes at their inner ends being spaced from each other, the space between said parts gradually increasing in width from the outer to the inner ends of the vanes and 1 opening into said body portion.

In testimony whereof, I afiix my signature hereto.

WILLIAM C. TORBETT.
