Specification Accepted, 9th Sept,, 1887.
We JOHN NIGHTINGALE and JOSEPH NIGHTINGALE of Paterson in the County of
Passaic and State of New Jersey United States of America, Manufacturers, do
hereby declare the nature of our invention for IMPROVEMENTS IN TAKE-UP MECHANISM
FOR LOOMS and in what manner the same is to be performed to be particularly
described in and by the following statement :-
The object of our present invention is that the cloth beam in looms take-up and
wind the woven fabric on the same at an even rate of speed throughout. We attain
the object sought by the devices illustrated in the accompanying drawing, which will
be hereinafter fully described and pointed out in the claims.
Fig. 1 of the drawing shows in elevation one side of an ordinary loom with our
invention attached. Fig. 2 shows in elevation a portion of the opposite side of the
loom with our invention attached, in which figure a portion of the supporting frame,
crank arms, etc. are removed. Fig. 3 is a part front elevation of the same with our
invention attached in which figure a portion of the frame, shafts, rollers, rods, etc. are
removed. Fig. 4 is a detached sectional view of our invention taken on line x x of
fig. 3 in which figure the roller shaft and frame are shown in elevation. Fig. 5 is a
modification of that shown in fig. 4, and Figs. 6 and 7 are still further modifications.
A represents a loom of ordinary construction in the frame A¹ of which loom is
journalled the usual driving shaft e, which shaft connects with the lay c¹ by means of
crank arms and vibrates lay sword c² with lever h arranged thereon. The lever h
which is pivoted to the lay sword at the top and is arranged in a guide at the bottom,
connects with the teeth of the ratchet wheel by means of a hooked arm ¹ that is
pivoted to the said lever h and actuated thereby and which imparts to the ratchet
wheel an intermittent movement. The ratchet wheel which is journalled on a stud
fastened in the loom frame, connects by its integral pinion with a gear wheel and
actuates said gear with its pinion both of which are journalled on a stud fastened
in the loom frame while a pawl g which engages the teeth of said ratchet wheel f
holds the same from reverse rotation. The gear by its pinion gears with and
actuates a gear wheel arranged on roller F. The draft roller F is journalled in
the loom frame and is provided with a gear wheel E that gears with an intermediate
gear E', which last mentioned, gears with and actuates a toothed wheel D, hereinafter
more particularly referred to. The loom which is constructed as is usual need not it
is thought to be further described herein.

page_text: In suitable bearings, that are arranged in the loom frame we journal a cloth beam
C, on one end of the shaft of which cloth beams we arrange flanges H and H which
flanges are provided on their inner surfaces with a leather friction plate H². Said
plates are fastened to the flanges by rivets.
n³
Between the flanges H, H¹, we arrange a toothed wheel D above referred to. The
toothed wheel D which we journal on the roller shaft and between the flanges H and
H' thereon gears with, and is kept in continuous rotation by an intermediate gear E¹
that meshes with a gear E fixed on the draft roller F. The outer end of the shaft of the
cloth beam C we provide with a screw thread n, on which we arrange thumb nuts n²,
each one of which nuts we provide with a corresponding screw thread to that on
the shaft of the cloth beam which adapts the nuts n' when the same is turned forward
to bring flanges H, H', into frictional contact more or less forcible against the sides
of the toothed wheel D to place a suitable tension on the cloth to cause the same to
wind tightly on the cloth beam C while nut n² is adapted to hold, or lock, nut n¹ in
its adjusted position on the shaft and against the flanges H, H' the latter of which
is fixed on the shaft of the cloth beam C by a set screw H³. The toothed wheel D
which is kept in continuous rotation by wheels E, E¹ by its frictional contact with the
leather plated flanges H, H¹, turns the cloth beam C and winds the woven fabric e on
the same as the fabric is delivered from the draft roller F. As the draft roller draws
the warfes from the roller a' through the loom and the fabric over the roller a and the
operation of weaving is continued. And the tension on the cloth is increased by the
continuous enlargement of the cloth beam by the winding of the cloth thereon. Such
increase of the tension on the cloth caused by such enlargements of the cloth beam,
will cause the flanges H, H', to slip on the wheel D, and thus permit the cloth beam
to decrease its speed in keeping with its growth to take-up and wind the cloth on the
beam at an even rate of speed throughout.
In the modified form of figure 5 the the wheel D revolves on the flange H' that is
keyed on the roller shaft, and having threaded studs to accommodate thumb nuts by
which the flange H is forced against the toothed wheel D. While in figure 6, the
toothed wheel D is made in two separate parts the inner rim of which wheel is in
frictional contact with a leather band K2 arranged in a groove K₁ of the ring or
flange keyed on the roller shaft, the parts of the toothed wheel being fastened
together in the groove and in frictional contact with the leather band by bolts K*
in lugs K of the same, while in figure 7 the toothed wheel is made a part of the
outer flange the inner beveled form of which conforms to the outer beveled form of
the flange B secured to the roller shaft, the parts D, B, being brought together for
friction by nuts n¹. n³ on thread n.
Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed, we declare that what we claim is
First. The toothed wheel D journalled on the roller shaft between flanges H, H¹
and flanges H, H³, having plates H³ adapted to engage wheel D and thumb nuts
n n², screw n all arranged and operating substantially as described.
Second. The combination with the wheel D flanges H, H³, thumb nuts, n¹ n³
arranged and operating as described, of the cloth beam C, the roller F and gears
thereon, lay c¹, c³, and lever h thereon, arm h¹, gear E¹, ratchet wheel f, pawl g,
rollers a, a, the shaft e, arms e³, and gearing substantially as described between the
ratchet wheel and roller F.
