IMPROVEMENT IN PEEDING-ATTAGHMBNT PGR COTTON-GINS.

TO ALL WHOM IT MAY CONCERN:

`Be it known that I, S. Z. HALL, of Camden, in the county of Camden, and State of New Jersey, have invented certain new and useful Improvements in Cotton-Gins; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a portion of this specifcatiom-in which- Figure 1 is a side elevation of a cotton-gin constructed according to my invention. Figure 2 isa plan or top view of the same. Figure 3 is a detached sectional view of a portion of the same. Similarletters of reference indicate corresponding parts in all the figures. Y This invention relates to that class of cotton-girls in 'which a rotating toothed cylinder is employed to convey the cotton bres to the ginning-saws; and it consists in a feeding-cylinder constructed of wire cloth or other equivalent reticulated material, and furnished with suitable teeth, in such manner that as the cotton is` passed vto the' saws the dust and dirt contained therein are allowed to fall through theA interstices of the wire cloth cylinder into the interior thereof, the cotton being greatly improved. in'quality by the removal of such impurities therefrom. The invention further consists in so arranging an adjustable pulley in relation'with the belt that drives the ginning-saws and the belt that operates the feeding-cylinder, that any desired tension of either or both of the said belts may be secured by simply changing the position of the aforesaid pulley, The invention further consists in so arranging a lever in connection with the pawl whichactuates the rollers by which the cotton is conveyed to the feeding-cylinder and with the breast of the gin, that the operation of the aforesaid lever simultaneously elevates the said breast and stops the motion of the rollers, whereby all dangei` of clogging the machine, bythe act of stopping the operation thereof, is effectually prevented. The invention further consists ina novel arrangement of parts for operating the feeding-cylinder, the ginning-saws, and brushingcylinder, whereby great eiliciency of operation and simplicity of construction are secured.

To enable others to understand the construction an d operation of my invention, I will proceed to describe it with reference to the drawing. l

Situated transversely in the forward end of a suitable box or casing, A, is the feeding-cylinder B, the construction of which will presently be fully explained, and which is supported upon a shaft, a, one end of which extends through one side of the casing A, and is furnished with a spur-wheel, b, which gears into a pinion, c, formed upon or attached to the inner side of a pulley, d, and situated underneath theaforesaid spurwheel Z2.` The bottom of that portion of the casing A back of the'cylinder B is composed of cylindrical rollers e, the shafts of which are connected at one end by spur-gearing, as shown at a I2 in iig. 2, in such manner that a movement communicated to one of the said rollers will be communicated to all the others, the said rollers receiving an intermittent rotary motion by means of a ratchetwheel,f, secured to one end of the shaft of one` of them, and acted upon by a pawl, g, pivoted to the lower end of a vibrating-lever, C, which may be pivoted upon the end of the shaft of one of the other rollers e, and the upper end of which is provided with a longitudinal slot, C', through which is passed a crank-pin or wrist, d', attached to and projecting out from the spurwheel b, in such manner that the rotation of the cylinder B communicates a vibratory motion to the leverC, and consequently works the pawl g to operate the ratchet-wheel f. In order to prevent any retrograde movement of the aforesaid rollers, two pawls, y L, are placed in rear of the ratchet-wheelf, asshown in fig. 2, in such manner as to keep the said ratchet-wheel from turning backward. D represents a bent lever, which is. secured upon the end of a transverse shaft, 7i, which works in suitable bearings underneath the casing A, the lower portion of the said lever being bent or curved back underneath the forwardly-projecting arm z' ofthe pawl g, as snown in fig. I. Secured upon the same shaft i as the lever I) is a downwardly-projecting arm, j, which is connected by a rod or link, k, with the breast E of the gin, the said breast being hinged at its upper end, as shown at m, in iig. 1, and being of any ordinary or suitable construction. By pushing forward the upper arm of the lever D the lowerA arm thereof will be caused to lift the forward end of the pawl g, thus 'depressing the rear end thereof and bringing it away from the ratchet-wheel f, and stopping the movement of the rollers e', simultaneously with which the arm j draws back the breast E, thus tilting or raising the same and bringing it i away from the ginning-saws, as requiredl when the operation of the machine is stopped, in order to prevent any liability of clogging the same. The aforesaid saws are located within a suitable chest or case, F, situated for. ward of the casing A, and lower than the same, and are placed upon a transverse shaft, one end of which is shown at n, and is furnished with a pulley, r. G and I indicate two band-wheels which are situated at one side or end ofthe gin-stand F. The ginning-saws are secured upon the shaft of the band-wheel G, and to one or the other of the said band-wheels a rotary motion is communicated by any suitable means. These band-wheels are connected by a band, J, the lower side or portion of 'which passes over and upon the upper side of the pulley, r, and thus communicates a rotary motion to the shaft thereof, and consequently to the brushing-cylinder which is situated npon the said shaft. K indicates a grooved pulley which is pivoted in a stirrup, L, which is attached to a supporting standard, M, by means of a pin, s, which projects from its upper end, and which, after being lpassed through avvertical slot, m', in the aforesaid standard, has screwed upon it a nut, a', whereby is rigidly attached to the said standard. This grooved pulley bears upon the upperportion of the band J, and is furthermore connectedowith the pulley l by a suitable belt, u, so that it operates not only as a friction-pulleyfto increase the tension of the ,band J, which operates the ginning-saws and the brushing-cylinder, but also to communicate the required rotary motion to the feeding-cylinder B; the pin s and the nut n enabling the aforesaid grooved pulley to be adjusted either to increase or diminish the pressure thereof upon the band J, or to tighten or loosen the belt u, as may be required. N shows apivoted apron situated in front of thefeeding-cylinder B, and designed to facilitate and secure the proper passage of the cotton from the aforesaid feeding-cylinder -to the breast and gnning-saws. The cylinder B is constructed as follows: Two circular heads c are connected by an annular series of longitudinal bars, w, and placedupon and around these bars w is a covering, x, of wire cloth which constitutes the sides of the cylinder. Secured in each of the bars wis a row of outwardly radiating teeth, z.

vThe unginned cotton being placed in the rear portion of the casing A, behind the feeding-cylinder B, the machine i's set in motion by the means hereinbefore described, andthe intermittent movement of the rollers e feeds the cotton forward-so that 'it is caught up by the teeth of the cylinder' and carried upward and over the same, and thence downward between the breast E and the ginning-saws. ,Asl thecotton is thus carried over the cylinder B the dust and dirt contained therein` arc caused to separate therefrom, and fall by their own gravity through the interstices of the wire-'cloth sides of the said cylinder B into the interior of the same, thus eifectually cleansing the cotton therefrom, and materially improving the quality of the same.

Vhat I claim as new, and desire to secure by Ictters Patent, is-

1. '.lhe reticulated toothed feeding-cylinder B, constructed and operating substantially as herein set forth, for the purpose specified. y j

2. The combination of the adjustable pulley K with the belt u which operates the feeding-cylinder, and the belt or band J which operates the ginning-saws, in such manner that the tension of the said belts may be adjusted or regulated by changing the position of the aforesaid pulley, substantially as herein set forth.

3. So arranging the lever D, in relation to the pawl g, and in connection with the breast E,that the same moi'ementofthe lever which raises the breast shall simultaneously stop the movement of the feeding-rollers e, substantially as herein set forth.

1 1. The belts u and J, operating in connection with the' pulley K, and arranged to aetuate the feedingcylinder, ginning-saws, and brushing-cylinder, substantially as herein set forth.
