IMPROVEMENTS IN LOOMS FOR WEAVING
Year: 1878

page_text: LETTERS PATENT to Thomas Stanley Carus, of Blackburn, in the County of
Lancaster, Pattern Maker, for the Invention of "IMPROVEMENTS IN LOOMS
FOR WEAVING."
Sealed the 6th December 1878, and dated the 18th June 1878.
PROVISIONAL SPECIFICATION left by the said Thomas Stanley Carus at
the Office of the Commissioners of Patents on the 18th June 1878.
THOMAS STANLEY CARUS, of Blackburn, in the County of Lancaster, Pattern
Maker. "IMPROVEMENTS IN LOOMS FOR WEAVING."
This Invention of improvements in looms for weaving relates, firstly, to apparatus
for stopping or receiving the blow of the shuttle and picker at each end of the
"pick; "and secondly, to the mode of holding and securing the spindle or rod upon
which the picker slides to and fro; my said improvements being designed for "over
pick" looms.
According to the first part of my Invention I dispense with the leather check
straps usually employed, and substitute therefor at each end of the slay a metal
finger arranged to operate in conjunction with a spring. The metal finger when at
rest stands in an upright position, being supported at its lower end upon a pivot.
When the picker strikes the upper end of the finger it will recede with the force
of the blow as far as the tension exerted by a spiral spring, to which the finger is
attached, will permit; the finger will then return to its former position, which is
determined by a stop, against which the finger rests. The spiral spring is attached
at one end to the lower part of the finger, and at its other end to a hook or pro-
jection, which is adjustable, so that the tension of the spring may be altered as
required. The pin upon which the finger is pivotted projects from a bracket
fastened to the lower part of the slay, and to an arm extending from this bracket
the adjustable hook or projection for regulating the tension of the spring is secured
by a screw bolt and nut.
Another arrangement of the finger and spring consists in making the pin, upon
which the finger is pivotted, to extend some distance through the lower part of the

page_text: finger. A spiral spring is slipped over the elongated pin, and is caused to press
against a boss, forming the lower part of the finger, by a nut screwed upon the
outer end of the pin. The inner side of the boss is provided with one or more
clutch teeth, the latter being taper or inclined on one side and square (or parallel
to the axial line of the pin) on the other, and these clutch teeth fit into corre-
sponding teeth in a boss on the bracket, from which the pin or pivot projects.
Thus, the finger may be moved backwards, as in the arrangement first described,
the square part of the clutch teeth answering as the stop on the return movement
of the finger, whilst the pressure of the spring upon the inclined surfaces of the
clutch teeth keeps the finger always against the stop, except when the finger is
struck by the picker, when the spring serves to cushion the blow.
According to the second part of my Invention upon the two ends of the rod or
spindle upon which the picker traverses to and fro I fit screw nuts. The spindle is
passed through holes in suitable .brackets or stands affixed above each end of the
shuttle box, and the nuts are screwed up against these brackets from the outside,
thus holding the spindle firmly and securely in position.
Lock nuts may be employed to prevent the nuts from becoming loose through
the vibration of the slay.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Thomas Stanley Carus in the Great Seal Patent Office on the 17th
December 1878.

This Invention of improvements in looms for weaving is designed for over
pick" looms, and relates to the check motion or apparatus for stopping or receiving
the blow of the shuttle and picker at each end of the pick.
According to my Invention I dispense with the leather check straps usually
employed, and substitute therefor at each end of the slay a metal finger arranged
to operate in conjunction with a spring.
In the accompanying Drawings Figs. 1 and 2 shew my Invention applied to the
slay of an ordinary over pick loom.
Figs. 3 and 4 shew my improved apparatus in plan views detached from the
slay.
Referring to the arrangement shewn in Figs. 1 and 3, a is the metal finger,
shewn (in Fig. 1) as when at rest standing in an upright position; it is supported
at its lower end upon a pivot or pin b. When struck by the picker c the end of
the finger will recede with the force of the blow as far as the tension exerted by
the spiral spring d, to which the finger a is attached, will permit (see dotted lines
in Fig. 1); the finger & will then return to its normal position, which is determined
by a stop or projection e, against which a corresponding stop or projection e¹ upon

page_text: the finger rests. The spiral spring d is attached at one end to the lower part of
the finger, and at its other end to a hook or projection g, which is adjustable (sec
Fig. 3), so that the tension of the spring may be altered as required. The pin b,
upon which the finger a is pivoted, projects from a bracket h fastened to the
lower part of the slay, and the adjustable hook or projection 7 for regulating the
tension of the spring d is secured by a screw bolt and nut k to an arm; extending
from the same bracket h.
In the arrangement shewn in Figs. 2 and 4 the pinion b, upon which the finger a
is pivoted, is made so as to extend some distance through the lower part of the
finger (see Fig. 4). A spiral spring d is slipped over the elongated pin b, and is
caused to press against a boss l, forming the lower part of the finger, by a nut m
screwed upon the outer end of the pin b. The inner side of the boss is provided
with one or more clutch teeth, the latter being taper or inclined on one side and
square (or parallel to the axial line of the pin b) on the other, and these clutch
teeth fit into corresponding teeth in the boss of the bracket, from which the pin
or pivot b projects. Thus the finger a may be moved backwards, as in the arrange-
mont first described, the square part of the clutch teeth answering as the stop on
the return movement of the finger, whilst the pressure of the spring & upon the
inclined surfaces of the clutch teeth keeps the finger always against the stop, except
when the finger is struck by the picker c, when the spring serves to cushion the
blow.
In Fig. 1 I have shown the ordinary mode of holding the picker spindle n
Another mode is shown in Figs. 2 and 5, but this I do not wish to claim as a part
of my said Invention.
Having now described the nature of my said Invention, and explained the
manner of carrying it into practical effect, I would have it understood that I do
not claim as of my Invention or the exclusive use of the several parts herein-beforo
described or referred to, except when the same are used in and for the purpose of
my said Invention; but what I consider to be novel and original, and therefore
claim as the Invention secured to me by the herein-before in part recited Letters
Patent is,
1. Constructing the check motion with a finger arranged to arrest the motion of
the shuttle, substantially as herein-before described.
2. The arrangement shewn in Figs. 1 and 3.
3. The arrangement shewn in Figs. 2 and 4.
In witness whereof, I, the said Thomas Stanley Carus, have hereunto set my
hand and seal, this Thirteenth day of December, in the year of our Lord
One thousand eight hundred and seventy-eight
