GIN BRUSH.

Application Filed October 19, 1,926, Serial No. 142,660. Renewed March 5, 1929.

This invention.aims to provide a device for removing lint from the saws of a'cotton gin, and one object of the invention to providea novel means whereby the lint may be removed by blowing, rather than by the attrition of brushes. i

Another object of the invention is to facilitate the mounting of the cleaner in such a waythat it Vwill run truly, even though the shaft which carries it may be a trifle ecceir tric, y i y 1` y y y i.

1t is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invcntion appertains.

lWith the above and other objects in View which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the de tails of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

ln the drawings Figure 1 shows in sectional elevation, a device constructed in accordance with the invention, parts being broken away;

Figure 2 is a section on the line 2-2 of Figure 1;

Figure 3 is a sectional view illustrating the means for holdingthe blades in place.

rlhe device forming the subjectmatter of this application includes a tubular body B made up of end members 1 and intermediate members 2, in the form of plates, the intermediate members 2 having annular shoulders 3 on each side, and the end members1 having corresponding shoulders on their inner sides only. rIhe shoulders 3 lit within tubular casings 1 which abut at their ends against the intermediate membcns 2, or against one of the intermediate members 2 and one of the end members 1.

Hub plates 5 are attachedby securing elements 6 of any desired construction, to both sides of the end members 1 and of the intermediate members 2. The hub plates carry tubular hubs 7 in which are mounted radially adjustable holding devices, such as screws t3. The end members 1 and the intermediate members 2 are supplied with openings 9 which register with the bores of the hubs 7.

Si ii A shaft l() is extended through the bores of the hubs 7, and through the openings 9, the bores and the openings being of such diameter that the body of the device may be shifted transversely of the shaft 10,1by means of the screws 8, which bear at their inner ends onthe shaft 10. The operator always has within his control, a means whereby the body of the device may be trued up, so as to run fairly with respect to an axis of rotation, without eccentricity, or a wobbling motion. Hammering thus is avoided, and the ditlieulty of keeping up thc bearings, for the shaft 10 will be reduced materially.

The end members 1 and the ,intermediate members 2 extend outwardly beyond the shoulders 3 and the casings a to form, in cach of the members 1 and 2, a reduced rim 11. In thc rim 11, transverse seats 12, of a blunted triangular form, are fashioned, the seats extending entirely through the rim from side to side. Plate-like blades 14, made of metal, extend `the full length of the body 1, the outer edges of the blades being folded over to form reinforcing wings 15 which are in contact with the main part of the blades, as shown in Figure Each blade 14 has an extension 16, disposed at an obtuse angle to the main part of the blade, the extension 16 lying along one wall of the seats 12. The extension 16 is of the same length as the main part of the blade 14, and the same observation holds true with respect to a foot flange 17 disposed at an acute angle tothe extension 16, the foot flange resting on the base or inner edge of the Aseat 12, and upon the casings et between the intermediate members 2, and between the intermediate members and the end members 1. The bla d-es are held in place by retainers 18, preferably in thefor-m of bars, mounted in the seats 12 and of blunted triangular form, to agree with the cross section of the seats 12. The retainers engage the foot flange 17, and the extension 16 and bear against that edge or wall of the seat 12 which is opposite to the extension 16-all as shown in Figure 3. Securing devices 19, such as screws, extend inwardly through the retainers 18 and the foot flange 17 and enter the end members 1 andthe intermediate members 2. The securing devices 19 prevent the retainers 18 `from shifting endwise, or from moving outwardly in a radial direction; but, owing to the blunted triangular form of the seats 12and of the retainers 18, considerable of theV radial or centrifugal strain will be j taken off the securing'devices 19.

When the structure is rotated, the blades 14 produce a blast of air and the cotton is blown from the saws.

repairs. The device is so constructed that it may be made of any desired length, the operator being free to use as many of the inteimediate members 2 and the casings 4 as occasion may demand. y As to the end members 1 and 2,the casings 3, the hub plates 5 and the I tainers'lB, and this is permissible.

hubs 7, and the .bladesllh the use of aluminum, or an aluminum compound, is sugi gested, With a View to cutting down weight,

reducing motive power to operate, and preventing swelling or warping. Some persons prefer to usev Wood in the'making of the re- For the sake of brevity, the'endy members 1 and the intermediate members 2 may be referred to as webs.

What is claimed is A gin saw cleaner comprising webs having peripheral notches which ta )er toward their outer ends, substantially radial blades having extensions disposed at an obtuse angle to the blades and prolonged along one wall of the notches, the edge portions of the webs overhanging the extensions, the extensions being supplied with circumferentially extended foot flanges prolonged along the bases of the notches, retainers in the notches and engaging the foot flanges, the retainers being tapered in cross section to conform to the taper of the notches, the retainers engaging the extensions to hold them in such position that the edge portions of the webs overhang the extensions, as aforesaid, and securing elements extended through the retainers and the foot flanges into the webs, those parts of the securing elements which pass through the retainers being located within the notches.

In testimony that I claim the foregoing as Vmy own, I have hereto axed m si nature.
