An Improved Cotton-gin Roller.
I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake, and Co. Patent Agents,
45 Southampton Buildings in the County of Middlesex do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
This invention relates to cotton-giu rollers and comprises the improvements herein-
after described with reference to the accompanying drawing. in which:
Figure 1 is an elevation of a cotton-gin roller embodying this invention.
Figure 2 is an enlarged longitudinal section of one end of the roller.
Figure
3 is a transverse section of Figure 2.
Figure 4 is a view of the layers or discs which constitute the body of the roller.
Similar letters of reference indicate similar parts in the several figures.
A is a metallic spindle or shaft constructed with the portion A within the body
and flanges of the roller, squared or rendered non-circular in section. B is the body
of the roller. This consists of a large number of discs or layers made of duck or other
suitable textile fabric each of which has a central hole of the size and shape to fit
the squared portion A¹ of the shaft A. C, Care thick flanges of substantially the
same diameter as the body of the roller, fitting upon the squared portion of the shaft,
and constructed of leather-board, raw hide or other sufficiently stiff non-metallic
material.
D, D are collars or plates secured to the shaft A by means of a pin D¹ as shown in
Figure 2. The said flanges have heretofore been constructed of metal, but it has
frequently happened that the gin-plate, striking against the said flanges has not only
injured the said plato, but has also set fire to the cotton the result being that many
serious conflagrations have been brought about in this manner.
The roller constructed in the following manner. A large number of the discs or
layers having been cut out with a die or the like in the form shown in Figure 1, a
few, say enough to measure four inches in thickness when laid together, are supplied
with cement preferably rubber, on their sides and are then pressed together on a
mandrel by a pressure of say sixty tons, with the effect of reducing the thickness of
the pile of discs from four to about two inches. These compressed discs are then
placed on the portion A' of the shaft and another lot treated in the same manner,
until enough layers or discs, many hundred in number, are placed in position to make
a roll of the suitable length, say three feet eight inches. The flanges C are then
placed in position, and driven up with a press, and then the collars or plates D are
secured to the shaft in the position shown. The surface of the body of the roller is
then made even by grinding or other suitable method, and the spiral grooves Ę cut by
means of a suitable tool.
I am aware that layers or discs of fabric have been employed in a manner some-
what similar to that above described, and also that there have been interposed between
such layers, coatings or dises of vulcanized rubber. In my invention I use unvul-
canized rubber cement, and I especially desire to disclaim the use of vulcanized rubber
for the reasons that dises of vulcanized rubber are liable to catch fire, and, even
when made as thin as possible tend to wear out the roller.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, as communicated to
me by my foreign correspondent, I declare that what I claim is :-
First. The herein described improved cotton-gin roller comprising the following

page_text: paris, riz., a shift A, A, the body B formed of circular layers or discs of textile
fabric compressed and placed upon the said shaft, the collars D, and the non-metallic
Hanges constructed of leather-board, raw-hine or other sufficiently stiff non-metallie
material, the said flanges being placed between the said collars and the ends of the
body of the roller, substantially as set forth.
Second. The herein described improved cotton-gin roller, comprising the following
parts, riz.The shaft A A', the holy B formed of circular layers or discs of textile
fabric having their sides provided with unvulcanized rubber or cement and compressed
upon the said shaft, the collars D, and the non-metallic flangers (constructed of
leather-board, raw-hide or other sufficiently stiff, non-metallic material, the snid
flanges being placed between the said collars and the ends of the body of the roller,
substantially as described.
