ROVISIONAL SPECIFICATION.
Improvements in Drag, or Pacing, or Tension Regulating Apparatus
for the Warp Beams of Looms.
I, JOHN MORRISON, of Kirkton, Forfar, in the County of Forfar, North Britain,
Factory Manager, do hereby declare the nature of this Invention to be as follows, that
is to say:-
My said Invention comprises improved apparatus for applying and adjusting the
drag or pacing of the warp beams of looms for the purpose of regulating the tension
of the warps.
My improved apparatus comprises the following parts which are placed on one
end of a warp bean; namely a disk made with a tubular boss having internal ribs to
engage in notches or grooves in the end of the beam; a second disk fitted loosely on
the boss and having circumferentially ratchet, wormwheel, or spur teeth; a third
disk also loose on the boss of the first disk; and beyond the third disk a plate
which is bolted to the end of the boss of the first disk. Pins are screwed through
the plate so as to press the third disk more or less towards the first disk and
thereby grip the second disk more or less forcibly. Plies of flannel or other suitable
material are placed between the first and second and second and third disks. A
pawl, or a worm, or other detent is carried by or attached to the loom framing
and engages with the circumferential teeth of the second disk and keeps that disk
stationary, although it can be turned into any position when required on relieving
the detent. The second disk being held stationary as described causes resistance
to be frictionally opposed to the rotation of the other disks and of the warp beam
on which they are set; and such frictional resistance can be adjusted with great
nicety by means of the screw pins which are screwed through the end plate.
In some cases, my improved apparatus may be applied to both ends of a
warp beam.

COMPLETE SPECIFICATION.
Improvements in Drag, or Pacing, or Tension Regulating Apparatus
for the Warp Beams of Looms.
J., JOHN MORRISON, of Kirkton, Forfar, in the County of Forfar, North Britain,
Factory 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, that is to say:-
My said Invention comprises improved apparatus for applying and adjusting the
drag or pacing of the warp beams of looms for the purpose of regulating the tension
of the warps.
In carrying out my Invention I interpose an adjustable frictional appliance between
the warp beam or a part fixed thereon and a ratchet-toothed or other ring which
is stationary whilst the loom is working.
An example or modification of my improved apparatus is shown on an accompanying
sheet of explanatory drawings, figure, i, being a side elevation showing the back part
of a loom, figure, 2, a vertical section as at right angles to figure, 1, and figure, 3, a
sectional elevation as viewing the drag appliance from the inner side. In these
[D77

page_text: drawings the same reference letters are used to mark the same or like parts wherever
they are repeated.
The modification of my improved apparatus shown in the drawings comprises the
following parts which are placed on one end of the warp beam, A; namely, a disk, B, made
with a tubular boss, C, provided with internal ribs, D, to engage in notches or grooves
in the end of the beam, A; a second disk, E, fitted loosely on the boss, C, and having
circumferential ratchet teeth, F; a third disk, G, also loose on the boss. C, of the first
disk, B; and beyond or at the inner side of the third disk, G, a plate, HI, which is
bolted to the end of the boss, C, of the first disk, B. Pins, J, are screwed through
the plate, H, so as to press the third disk, G, more or less towards the first disk, B,
and to thereby grip the second disk, E, more or less forcibly. Plies of flannel, or other
suitable material are placed between the first and second disks, B, E, and between the
second and third disks, E, G, and these plies may be charged with black lead or other
substance to reduce the frictional action. A pawl, K, centered on a stud on the loom
framing is arranged to engage with the ratchet teeth, F, of the middle disk, E, and
hold that disk stationary, whilst allowing it to be turned for winding back the warp
upon the beam; the pawl being lifted out of gear when it may be required to turn the
beam in the unwinding direction.
The second or middle disk, E, being held stationary as described, causes resistance
to be frictionally opposed to the rotation of the other disks, B, G, and of the warp
beam, A, on which they are set ; and such frictional resistance can be adjusted with
great nicety by means of the screw pins, J, which are screwed through the end plate, F.
When the boss, C, is internally larger than the beam end, A, it may be fixed and
centered thereon by means of three radial screws tapped through the boss.
The

be entirely of iron, or mainly of wood, but in the latter case I
prefer to have the part on which the disk, B, with its tubular boss, (, is placed sheathed
with iron. Instead of the middle or second disk, E, being made with ratchet teeth, F,
with which a pawl, K, engages it may be made with worm wheel teeth or with
spur teeth, having in gear with them a worm or pinion by means of which the disk
can be turned when required.
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 :-
1. The improved tension regulating apparatus to be applied to one or each end of
the warp beam of a loom and consisting of a disk arranged to be stationary and to be
adjustably gripped between a pair of disks placed on and turning with the warp beam
substantially as herein before described.
2. The application to the warp beam of a loom of a frictional tension-regulating
device operating between the beam or a part fixed on the beam and a disk or ring
which is stationary during the working of the loom the pressure of the said frictiona
device being adjustable, substantially as herein before described.
