PROVISIONAL SPECIFICATION.
Improved Means for Holding Thrums in Looms.
I, JAMES LONGWORTH, of 192 Morris Green Lane, Middle Hulton, near Bolton, in
the County of Lancaster, Weaving Manager, do hereby declare the nature of this
invention to be as follows:-
The object of my Invention is to provide a means whereby the thrums may be
more securely held in their place, and yet be more easily withdrawn by the
weaver.
The principal feature of this Invention consists in the application of continued
pressure to the thrums, by means of a spring or an elastic band or a weight, in
connection with a frame of wood, or iron, or other suitable material.
A small board may be used, say, about 2 feet long 2 inches broad and an inch
deep several holes are bored in this board, near the ends, two abreast. Two cords
are passed through two or more of these holes and fastened to a spring which, when
the thrums are put under the cords, presses them against the face of the board.
Dated this 27th day of August 1889.

COMPLETE SPECIFICATION.
Improved Means for Holding Thrums in Looms.
I, JAMES LONGWORTH of 192 Morris Green Lane, Middle Hulton, near Bolton,
in the County of Lancaster, Weaving Manager, 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:—
The object of my Invention is to provide a means whereby the thrums (thrums are
lengths of twist to piece to broken threads in the warp) may be more securely
held in their place and yet be more easily withdrawn by the weaver.
The principal feature of this Invention consists in the application of continued
pressure to the thrums by means of a spring an elastic band, or a weight, in
connection with a frame or apparatus of wood, or iron, or other suitable material.
In making the frame or apparatus of wood, I take a small board a Fig. 2 on
the accompanying Sheet of Drawings of any convenient size, say, two feet long,
two inches broad and half an inch thick. I bore several holes 6 near the ends of this
board say, two, four, or six, two abreast, and from half an inch to an inch asunder
crosswise of the board, and about two inches lengthwise of the saune. Through two,
or any even number of these holes, at one end of the board I pass a cord e of
hemp or cotton, or of any other suitable material.
I pass another similar cord through the same number of holes at the other end
of the said board. I now attach the two cords to, by preference, a spiral spring d
Fig. 1 at the under side of the board. I now put a bunch of thrums, e Fig. 2 under
the cords, which I tighten up to bring the spring into action, and which press the
thrums against the face of the board, and continue to do so as the bunch of thrums
decreases in size with a constant and almost uniform pressure.
In order to provide an easy way to insert the thrums under the cords, I connect one
of the said cords to the spring by an S shaped hook Fig. 1, which can be readily
unhooked, thereby slakening the spring and the cords.
In case it be desirable to insert the thrums under the cords without detaching them
from the spring, it may be done by cutting a slot g Fig. 3 from the edge of the
board to each hole, thereby making it possible to get the cords out of the holes
without detaching them from the spring, and which renders it quite easy to get the

pull them into thier original possition in the holes.
The frame or apparatus may now be attached to the loom in any way convenient
to the weaver, for instance by tying it to the loom top, or hanging it therefrom, or
by fixing it to any other convenient part of the loom.
In using an elastic band it is simply used in place of the cords and the spring
mentioned above.
In using a weight it is attached to the cords instead of the spring.
When an iron frame is used it may be bolted to the top or to some other part of
the loom, or, in making a new loom it may be attached to the same in the process
of casting.
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
1st. The application of continued pressure to thrums by means of a spring, an
elastic band or a weight, in connection with a frame of wood, or iron or other
suitable material, as set forth in the foregoing statement.
2nd. Any form of frame or apparatus to attain the object mentioned above by
substantially the same means.
Dated this 27th of May 1890.
