page_text: I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co., Patent Agents,
Southampton Buildings, in the County of Middlesex, do hereby declare the nature
of my 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 the class of cotton gins known as roller gins and it
consists in certain novel features of construction, arrangement and combination of
parts which will be readily understood from the following description.
In the accompanying drawing
Figure 1 is a plan of a machine embodying this invention, one half of each of
two upper cross bars being broken away to show the parts beneath.
Figure 2 is a vertical section on the line x, x Figure 1.
Figure 3 is an end elevation.
Figure 4 is a vertical section of a portion of the upper part of the machine on the
Baine line as Figure 2 but drawn to an enlarged scale.
Figure 5 is a plan of one of the plate pressing levers and portions of the beater
cylinder and breast plate also enlarged, and,
Figure 6 is a rear elevation of a portion of the pin carrying bar and an
attaching cap.
A A are the main frames of the machine connected together by the bars B, C,
the feed table D and the plates E and F, said frames being slotted upon their
upper sides to receive the boxes a, b and a
Gis the ginning cylinder having its periphery covered with leather & and
mounted in bearings in the boxes b, b, shown only in dotted lines in Figures 2, 3.
and 4, said cylinder being arranged with its upper surface slightly above the upper
surface of the feed table D and having a rotary motion imparted thereto in the
direction indicated by the arrow 1 on Figure 3, by means of the belt I leading from
a pulley I¹ on the shaft of said cylinder.
Above the cylinder G and mounted in the boxes a, a is the beater cylinder K,
provided with a series of oblique discs e, e arranged with their peripheries in

page_text: contact with, or in close proximity to, the periphery of the cylinder G, said
cylinder K being revolved in the direction indicated by the arrow 2 on Figure 3,
by means of the crossed belt L leading from the pulley L' on the driving shaft to
the pulley K on the shaft of said cylinder, as shown.
A thin metal breast plate f having its underside curved transversely and its
upper side bevelled towards one edge, rests upon the periphery of the cylinder G
with its bevelled edge towards the feed table, but a short distance to the rear of a
vertical plaue extending longitudinally through the axis of said cylinders G and K.
Said breast plate extends the whole length of the cylinder G and is held in position
thereon by the pad like forward ends of a series of levers M, each pivotted to the
undor side of the bar B and having pivotted to its rear end the bolt N which
extends up and through an open slot ġ formed in the rear edge of the bar B and
has fitted thereon the spring h, washer h¹ and adjusting nut has shown in
Figures 1, 2 and 4.
Each of the levers M has formed in the under side of the pad at its front end a
shoulder i, which abuts against the rear edge of the breast plate f to prevent said
plate being moved to the rear and downward by the revolution of the cylinder G.
The bar C is preferably cast in one piece with the caps C, and has set in its
under side a series of downwardly projecting pins i¹ as shown in Figures 4 and 6,
which while they will permit the cotton seeds to pass then as they are thrown out
over the breast plate fand the pads of the levers M so that they will fall upon the
inclined plate E and thence to the floor outside the plate F, will serve to arrest any
fibre which may be carried over the breast plate f and cause it to be carried around
with the cylinder K and united with the cotton being fed to the ginning cylinders.
A shaft O is mounted in bearings in the boxes c, c and has secured thereon two
or more hubs provided with a plurality of radiating arms. The extremities of the
said arms are connected together by the longitudinal bars or plates j, j, which bars
or plates are arranged to serve as strippers to clean any fibre from the cylinder G
that may adhere thereto after it has passed the breast plate fand cause it to fall
upon the floor inside of the plate F. A rotary motion in the direction indicated by
the arrow 3 on Figure 3 is imparted to said shaft and bars by means of the belt P
leading from the pulley P¹ on the driving shaft to the pulley P on said shaft O.
The boxes c, c rest on the bottoms of the slots formed in the frames A, A, and
the boxes b, b rest upon the boxes c, c while the boxes a, a are adjustable up and
down in said slots by means of the set screws kk. The said set screws work in
threaded holes in the boxes, a, a, after passing through snooth holes in the caps C¹,
and rest at their lower ends upon the boxes b, b as shown in Figure 4 whereby the
cylinder K may be adjusted towards or from the cylinder G.
The bar B is secured to the frames A at each end by the bolts which pass
through slotted holes in said bar and are screwed into said frames so that said bar
may be adjusted towards or from the cylinder K by means of said bolts and slots
and the set screws m, for the purpose of properly locating the breast plate f.
By the use of the series of independently movable levers M, arranged to press
upon the breast plate f, one portion of the plate f may rise to permit the passage of
a bunch of fibre while other portions are held down by the levers not immediately
affected by the passage of said bunch, it being understood that said breast plate f
is made sufficiently thin to permit it to spring under such circumstances.
Having now particularly described and ascertained the nature of the said
invention 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 In a cotton gin, the combination of the ginning cylinder; the breast
plate and the series of spring pressed levers each provided with a shoulder to
abut against the rear edge of said plate all constructed, arranged and adapted to
operate substantially as, and for the purpose, described.
Second-The combination in a cotton gin; of a ginning cylinder; a breast plate,
a series of pivotted levers each provided with a shoulder to abut against the rear

page_text: edge of said plate and a pad to rest upon said plate; a bolt pivotted to each of said
levers and provided with a nut, a washer and a spring; and a bar provided in one
edge thereof with a series of open slots, to receive said bolts, substantially as
described.
Third The combination in a cotton gin, of a ginning cylinder; a breast plate;
a series of spring pressed levers each provided with a shoulder to abut against the
rear edge of said plate and a pad to rest upon the upper side of said plate; and a
beater cylinder provided with a series of obliquely arranged discs, substantially as,
and for the purposes, described.
Fourth The combination of the bed cylinder G, the plate f, the series of levers M
each provided with a nut, a washer and a spring; the slotted bar B; the beater
cylinder K; and the bar O provided with the series of fingers or pins i¹, all
constructed, arranged and adapted to operate substantially as described.
Fifth The combination of the cylinders G, K. the boxes a, a bb, the caps C¹ and
the set screws k, k, substantially as described.
Sixth In a cotton gin, the combination of the ginning and beating cylinder;
a breast plate; an adjustable bar provided with a series of open slots; a series of
levers pivotted to said bar and each provided with a shoulder to abut against the
rear edge of said plate and a pad to press upon the upper side thereof; a bolt
pivotted to each of said levers and arranged to engage with the slots in said bar;
a nut fitted to the upper end of each of said bolts so as to be adjustable thereon and
a washer and a spring mounted upon each of said bolts between its nut and said
bar, substantially as described.
