PROVISIONAL SPECIFICATION.
An Improved Terry Motion in Looms Used in Manufacturing
Towellings.
We, JOHN HAYDOCK, Engineer and Machine Maker and WILLIAM ROSSETTER
Manager, both of the firm of Wm. Dickinson & Sons, Phoenix Iron Works, Blackburn
in the County of Lancaster 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:
Our invention relates to mechanism on or connected with the crank shaft or going
part of the loom, for operating upon the stop rod, and forming the required loops
for towelling.
We employ a small pinion on the crank shaft of the loom, which gears with a
larger pinion or change wheel on a stud attached to the loom frame, this pinion carries
a stud, projection, or swell, which as the wheel revolves come in contact with a
pivotted lever or catch, which is in close contact with an arm from the stop rod, when
this arm comes in contact with the lever or catch, the reed is thrown back, and so it
does not properly beat up, leaving a space in the piece, when the arm clears the lever,
it brings the duck bill under the heater and beats up forming the loop. By using
change wheels on the stud the number of picks put in before the loop is formed can
be increased or diminished.
Or instead of the pinion wheel on the crank shaft we employ an eccentric and strap
on the crank shaft with a connecting rod carrying a catch, which comes forward to
the finger on the frog; there is also a catch on the stop rod which comes in close
contact with the frog, the connecting rod is connected to the pivotted lever or catch
beforenamed and when the catch comes in contact with the finger of the frog, it draws
the frog forwards bringing it in contact with the finger on the stop rod and pushes back
the reed as before described.
Or the studs or projections of the wheels may act directly on the rod from the
eccentric for operating upon the frog as before described; or a pivotted lever may

page_text: have one end connected to the slay or going part, its other end carries an arm to
which is attached the lever carrying a catch to engage with the frog finger, this lever
is operated in a similar manner as before described, by a projection or stud upon the
gear wheel placed in a suitable position.

COMPLETE SPECIFICATION.
An Improved Terry Motion in Looms Used in Manufacturing
Towellings.
We JOHN HAYDOCK Engineer and Machine Maker and WILLIAM ROSSETTER
Manager, both of the firm of Messrs. William Dickinson and Sons, Phoenix Iron
Works, Blackburn in the County of Lancaster, do hereby declare the nature of the said
Invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
Our invention relates to mechanism on or connected with the crank shaft or
going part of the loom, for operating upon the stop rod, and forming the required
loops for towelling.
We employ a small pinion on the crank shaft of the loom, which gears with a
larger pinion or change wheel on a stud attached to the loom fraine, this pinion carries
a stud, projection or swell, which as the wheel revolves comes in contact with a pivotted
lever or catch, which is in close contact with an arm from the stop rod, when this
arm comes in contact with the lever or catch, the reed is thrown back, and so it does
not properly beat up, leaving a space in the piece; when the arm clears the lever it
brings the duck bill under the heater and beats up, forming the loop; by using change
wheels on the stud, the number of picks put in before the loop is formed can be
increased or diminished as desired.

page_text: pinion B carries a stud, projection, or swell F which as the wheel revolves, comes in
contact with a pivotted lever or catch G which is in close contact with an arm H,
from the stop rod J, when this arm comes in contact with the lever or catch G,
the reed is released or thrown back, and so it does not properly beat up leaving
a space in the piece; when the arm H clears the lever, it brings (by ineans of
the spring 0) the duck bill K under the heater L which makes the reed fast
and beats up forming the loop, by using change wheels on the stud E the number
of picks put in before the loop is formed, can be increased or diminished as
desired.
On a fast reed loom see Fig. 3 fixed in a bearing attached to the slay sword N
upon each side of the loom, we place an eccentric P, to which is fixed the crank
arm R which connects the crank and slay-sword the eccentrics are fixed upon a
shaft S, which passes across the loom, at the end of each shaft we fix the
arm H which comes in contact with the pivotted lever G and operates as before
described.
By this means when the lever H is not in contact with the catch G, the
spring moves it and the eccentrics upon their shaft, so preventing the slay from
fully beating up until the catch G again comes in contact with the arm H as before
described.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is
1. For Joose reed looms the combination of the wheels A. and B, lever or catch G
operating (by means of a projection, swell or stud F) upon the arm H, pivotted on
the stop rod, and releasing the reed, substantially as and for the purposes shown and
described.
2. For fast reed looms, the combination of the wheels A and B, lever or catch G
operating (by means of the stud or swell F) upon the arm H, and eccentric P, as and
for the purposes shown and described.
3. The arrangement of apparatus whereby the number of picks put in before
the loop is formed can be regulated as required, substantially as shown and
described.
4. The general arrangement of apparatus substantially as shown and described.
