An Improved Take-up Motion for Looms for Weaving.
Year: 1894

page_text: Date of Application, 6th Nov., 1894
Complete Specification Left, 6th Aug., 1895-Accepted, 6th Nov., 1895
I JOHN GEORGE HARRISON, of 432, Manchester Road, Bury in the County
of Lancaster, Mechanic, do hereby declare the nature of this invention to be as
follows:-
This invention relates to an improved beam and roller motion, for the more
accurate manufacture and winding of fabric in looms, and to dispense with india-
rubber coverings, levers and weights.
I accomplish my object with cog-wheels, and bearings to same, with slot-holes or
grooves for regulating same to any required position.
Each beam or roller is provided at either or both ends with one cog-wheel; and an
intermediate or gearing wheel is fixed on bearings to the end of the frame in such a
position and in such a manner that it keeps both beams or rollers absolutely
parallel throughout the winding of the fabric, which is carried over the brest-beam
by means of the fluted or sand-beam, then passed over the smoothing-bar and taken
up on the lower-beam in the usual manner.
The intermediate wheel is provided with a catch by which it may be thrown out
of gear in case of accident, or when finished the fabric can be instantly drawn back
or pulled off.
Dated this Fifth day of November 1894.
LOWTHER HANSON,
For John George Harrison,
432 Manchester Road, Bury, Lancashire.
COMPLETE DI FUIFICATION.
An Improved Take-up Motion for Looms for Weaving.
I JOHN GEORGE HARRISON of 432 Manchester Road, Bury in the County
of Lancaster, Mechanic, 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 "An improved take-up motion for looms for weaving" for
the more accurate manufacture and winding of fabric in looms, and to dispense with
india-rubber coverings, levers and weights.
I accomplish my object with cog-wheels and bearings to same, with slot-holes or
grooves for regulating same to any required position.
Each beam is provided at one or both ends with a cog-wheel, and an intermediate
or gearing wheel is fixed on bearings to the end of the frame in such a position and
in such a manner that it keeps both beams absolutely parallel throughout the
winding of the fabric which is carried over the breast-beam by means of the fluted
beam, then passed over the smoothing-bar and taken up on the lower beam in the
usual manner.

page_text: And now in order that this invention may be fully understood, I shall proceed
more particularly to describe the same and for that purpose shall refer to the several
figures on the annexed sheet of drawings by letters of reference :-
Fig. I shows the end elevation of that part of a loom which relates to the
improved take-up-motion. The dotted line X represents the fabric, and the arrows
indicate the direction which the fabric takes in its course from the breast beam F
to fluted beam A, round smoothing bar K, on to lower beam A¹.
The cog-wheel B is fixed to end of fluted beam A by means of an ordinary set-
screw C cog-wheel B₁ is fixed to end of lower beam A' and is provided with
slot-hole bearings B", and the intermediate wheel D runs ou a stud d, and is held in
position by means of a sectional groove or bearing E fixed to the loom end H by
bolts J. This wheel D may be set to any part of the sectional groove E and will
always be in gear with cog-wheel B, except when purposely thrown out of gear for
which a catch d' (Fig. 11) is provided.
It is this wheel D also and its connection with the other two B and B¹, which
does away with the necessity of levers and weights, as by this means the two beams
are kept absolutely parallel throughout the winding of the fabric.
The cog-wheel B attached to fluted beam A is acted upon by the usual ratchet
wheel which in its turn drives the intermediate wheel D. This intermediate wheel D
then drives and controls the wheel B' which is fixed to the lower beam A¹ in the
manner stated above.
The two beams A and A' thus connected and controlled must of necessity revolve
at a uniform rate, but as the diameter of the cloth roll increases on the lower
beam A it produces a slightly increased friction upon the fluted beam A.
When greater winding space is required the intermediate wheel D may be
brought into direct line with the two cog-wheels B & B and thus obtain winding
space for 300 or 400 yards of ordinary fabric.
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 :-
An arrangement of cog-wheels constructed substantially the same and for the
purpose stated in the foregoing Specification.
