Improvements in or Applicable to Looms for Weaving Honey-
comb and Turkish Towels and other Fringed and Terry
Manufactures.
We THOMAS HIRST of 21 Paddock Street, Ardwick, Manchester, Smallware
Manufacturer and JOHN MIDDLETON of Aitkin Street, Levenshulme near Manchester,
Joiner do hereby declare the nature of our 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 improvements upon an Invention for which Letters Patent
No. 2837 and dated 27 Feby. 1886 were granted to us and consists 1st in the
application of an additional lever one arm of which is attached to a weighted cord
coiled round the intermediate warp beam (over which the warps pass at the back of the
loom) and the other arm connected to the levers fixed to the head of the loom so as
automatically to take off the weight from such intermediate beam as required for
weaving terry and putting it on when weaving plain.
2nd in the application of a self-acting stopping device which can be lowered so as
to act upon and close the reed simultaneously with and as soon as the front lever
lowers and stops the terry motion and
3rd the employment of an additional ratchet wheel with pawl capable of elongated
movement for quickening the speed of the cloth roller whilst weaving fringe.
On the accompanying drawing Fig. 1 is a front elevation and Fig. 2 an end
elevation of so much of a loom as is necessary to explain the application of our
improvements which are shewn applied thereto.
In both the views a is the lever fixed to the head of the loom in accordance with
our former invention and which is connected at one end by a cord to the drop box or
revolving shuttle box and at the other end by a cord to the weft fork.
In our present invention we apply an additional or side lever h the front arm of
which is connected with the weighted arm of the lever a so as to rise and fall
therewith and the other arm of this same lever is connected as illustrated to a
weighted cord i the other end of which is coiled round the intermediate warp beam j
(over which the warp passes at the back of the loom) and secured at its other
extremity to the framing p or any other stationary part of the loom.

page_text: In this manner we secure that the weight k affixed to the cord i shall be lifted and
so withdraw the weight from the intermediate warp beam simultaneously with the
weighted arm of the lever a being lowered say when it is required to weave terry and
which weight is again released and exerts its retarding influence upon the intermediate
beam as the, lever a rises once more say when plain weaving is required.
And in order to close the reed simultaneously with the lowering of the front lever a
we apply a self acting stopping device consisting of a catch mounted upon a bracket m
at the back of the breastbeam-which catch is connected by a cord n with the lever a
and is designed when lowered to come in contact with the top of the terry motion
lever rod o and so to stop the terry.
This catch being connected by the cord n to the lever a is released again as soon as
the said lever rises and so puts on the terry motion.
Our further improvements relating to the quickening of the speed of the cloth
roller A as illustrated on a larger scale by side sectional view in Fig 3. consist in
elongating the stud B upon which the ordinary ratchet wheel C of the cloth roller
winding mechanism is mounted so as to accomodate an additional ratchet wheel D
by preference of large diameter. The pawl E for operating this ratchet wheel is
mounted upon the usual swinging arm Fat the back of the slay and at such a height
thereupon as to partake of an elongated movement across several teeth of the ratchet
wheel D at each traverse and so to actuate the same at an augmented speed.
This pawl E however is also suspended by a cord G from the longer arm of the
front lever a and thus is only allowed to catch in the teeth of its ratchet wheel D
when the lever a is "timed" to stop the shuttles and to lift the weft fork say during
the making of the fringe. At all other times the ordinary ratchet mechanism for
operating the cloth roller is in action and performs its functions in the usual
manner.
The application of these improvements to a loom renders it possible to weave
honey-comb and Turkish towels and other fringed manufactures thereupon in any
desired colors and length of fringe in continuous lengths and to effect all the
desired changes automatically and without stopping the loom.
Having thus particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
1st. The improved combination and arrangement of mechanism for automatically
putting on and taking off the weight from the intermediate warp beam substantially
as and for the purpose herein before described and illustrated on the accompanying
drawing.
2nd. The self acting device for closing the reed substantially as and for the purpose
herein before described and illustrated on the accompanying drawing.
3rd. The employment of an additional ratchet wheel and pawl mounted and
suspended as hereinbefore described for operating the cloth roller and driving the
same at an accellerated speed substantially as and for the purpose hereinbefore
described.
