Complete Specification Accepted, 29th Jan., 1889
I, WILLIAM TYRALL BROWNE of 76 Prussia Street, Ancoats, Manchester, in the
County of Lancaster, Mechanical Engineer do hereby declare the nature of this
invention to be as follows:-
This Invention relates to the method of and means for operating the knife in
machines employed in the manufacture of surgical lint, and it has for its object to
effect the operation of the knife by simpler means or devices than those hitherto
employed.
The knife has a vertical and an horizontal motion imparted to it. According to my
Invention I derive the motion of the knife bar from a horizontal reciprocating rod
pivoted upon a vertical crank or eccentric rod or lever having an adjustable fulcrum
or pivot. One of these devices is connected to each end of the knife bar.

Improvements in Machinery Employed in the Manufacture of
Surgical Lint.
I, WILLIAM TYRALL BROWNE formerly of 75 Prussia Street, Ancoats, and at
present residing at 1 Abbott Street, Livesey Street Manchester in the County of
Lancaster, Mechanical Engineer, 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 the method of and means for operating the knife in
machines employed in the manufacture of surgical lint, and it has for its object to
effect the operation of the knife by simpler means or devices than those hitherto
employed.
And in order that my Invention may be more readily carried into practical effect,
I have appended two sheets of Drawings. In each of the figures similar parts are
denoted by similar letters of reference.
Fig. 1 is an end view and Fig. 2 is a side view of a machine having my Improve-
ments applied thereto. Figs. 3, 4, 5, 6, and 7 represent details of the Improvements.
The general construction and arrangement of the machine with the exception
hereinafter particularly described, does not differ in any material respect from other
machines of a similar character already in use.
A is the cloth or fabric which has to be converted into lint and which is supplied to
the machine in a roll B. From this roll the cloth passes around the rollers C. D. E. F;
whence it passes under the linting knife G, around the roller H, and taking up
roller I. J is the first motion shaft from which the second motion shaft K is
driven by the worm and worm wheel L. From the second motion shaft the roller F
is driven by the gearing wheels 1, 2, 3, 4, 5, 6, 7, and 8; while the taking up roller
is driven from the same shaft by the pullies 9, 10, the worm 11, and the worm wheel 12
which is mounted on the shaft of the friction roller 13.
The knife G has a vertical and horizontal motion imparted to it and it is the con-
struction, arrangement and combination of devices and apparatus for imparting the
desired motion to the knife which constitute my Improvements, and which are
represented on a larger scale by the detail drawings Figs. 3, 4, 5, 6, and 7.
G is the knife which is mounted upon the slide M capable of vertical motion in
the knife carrier N. At each end of the slide M there is a trunnion O on which is
mounted a bowl P. At each end of the knife carrier there is also a trunnion or pin Q
upon which is pivotted one end of the arm R the other end of which is pivotted to
the swing franie S, Figs. 3, 4, and 5, or an equivalent crank or eccentric rod as shewn
in Fig. 6 and 7. An oscillatory motion of the frame or rod S is derived from the
eccentric T on the first motion shaft or from an equivalent crank pin, and the range
of motion may be regulated by the adjustable fulcrum U which is constructed to
permit vertical motion of the frame or rod S while at the same time preventing its
horizontal motion at the fulcrum. Since the arm R connects the frame or rod S to

page_text: the knife carrier N, the motion of S. will produce a horizontal reciprocating motion
of the carrier and consequently of the knife also. Since also, the bowl P rests
upon the arm R, the motion of S will produce a vertical motion of the bowl and of
the knife with which it is directly connected. The resulting motions of the knife
are: Descent, a forward scraping motion on the surface of the cloth, ascent, and a
retrogade motion, after which the cycle is repeated.
The knife is maintained in contact with the cloth in the first place by its own
weight and additionally, by means of the tension of a spring W which is connected
to the trunnion O and to a pulley Y on the shaft of the ratchet wheel Z. The tension
of the spring may be regulated by turning the ratchet wheel Z in the required
direction. The rotation of the ratchet wheel by the spring is prevented by a pawl
in the usual manner.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
In a linting machine; the construction, combination and arrangement of apparatus
for imparting horizontal and vertical motions to the knife; substantially as herein-
before described and as illustrated by the accompanying drawings.
