Improvements in Shuttles for Looms.
We WILLIAM ROCKE of 206 Ordsall Lane, Salford, in the County of Lancashire,
Mechanic, and WILLIAM PROSSER 13 Walmer Street Salford in the County of
Lancashire, Mechanic do hereby declare the nature of this invention to be as
follows:-
Our invention relates to shuttles used in looms for weaving and which is provided
with a tongue on to which is placed to cops of cotton, wool, or other suitable weaving
materials. The said tongues is provided with a spring one end of which is braized to
the outer or pointed end of the said tongue. The other end of the said spring is
secured loosely in the lower part of the tongue in which it is allowed to move freely
in a suitable opening.
The said tongue is formed on the lower part in a square shape through which passes
loosely a pin, which is secured to the shuttle, against the flat surface of the said
tongue presses a suitable spring to keep the same in its required position either hori-
zontal when in use, or vertical when it as to be provided with a fresh cop.
The object of our invention is to make such a shuttle more easier to handle, simpler
in its appliances and more economical when in use by reducing the waste of cotton,
wool, &c. resulting by the replacing of the cops when the shuttle is empty.
To effect this improvement we employ the same kind of shuttle and tongue as now
in use with the exception that the spring on the tongue is made without tension and
lies flat against the said tongue when in a vertical position but when the tongue is
provided with a fresh cop and is pressed downwards to its proper position for use, the
spring is then forced outwards and thus keeps the said cop firm in its position. This
is done in the following manner.
We place a spring near the pivoted end of the tongue. One end of the said spring
is fastened to the shuttle by suitable means, whereas the other end rests against the
tongue spring when the said tongue is pressed down to its working position; and by
this means the spring is provided with a tension to keep the cop firm in its place, but
this tension is released as soon as the tongue is turned to a vertical position and
by this arrangements the said cops can be placed onto the said tongue very easy,
without any force or damage to the cop thus avoiding all waste which is in the
ordinary shuttles at present in use very considerable.
To keep the said tongue in its place when in working position we provide the
shuttle with a lever pivoted to the said shuttle. One end of the said lever is provided
with a catch which lies against the tongue to prevent the same from shooting out-
wards. The other end of the said lever is provided with a suitable spring so as to
keep the catch always against the tongue, but as soon as the spring is pushed inward
the catch is withdrawn the tongue is released and the aforesaid spring will force the
tongue outwards and the same is ready again to receive a fresh cop.
By this improved arrangement simplicity, economy, in working and durability, is
effected.

Improvements in Shuttles for Looms.
We WILLIAM ROCKE of 206 Ordsall Lane Salford in the County of Lancashire
Mechanic, and WILLIAM PROSSER, of 13 Walmer Street Salford in the County of
Lancashire 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 :-
Our invention relates to shuttles used in looms for weaving which is provided
with a tongue and spring onto which is placed the cops of cotton wool or other
suitable weaving material and the object of our invention is to make such a shuttle
more easier to handle, simplier in its appliances, and more economical when in use
by reducing the waste of cotton wool &c. resulting from the replacing of the cops
when the shuttle is empty.
In order that the full nature and novelty (and mode of putting our said invention
into effect, or practic) may be properly understood we shall now proceed to describe
the several figures on the sheet of drawings which we have hereunto appended for
the purpose of reference, letters indicating the same parts in all the figures where ]
shown.
Fig. I represents longitudinal section of shuttle showing the tongue and spring in
working position.
Fig. I represents part section of shuttle and shows the tongue and spring ready to
receive the cop of cotton, wool, or any other substance used for weaving.
Fig. III represents the tongue and spring.
Referring to these figures our improvements consists as follows:-
To the shuttle a, is pivoted the tongue b, by means of the pin 6' on which it is
allowed to move freely; to the free end of the tongue b, is braised a spring c one
end of which fits loosely into the opening 6.
The shuttle a is also provided with a suitable shaped spring d which is kept in its
position by a pin d¹.
The spring d is so shaped that it will extend into the opening 6" of the tongue b
and at the same time resting against the square end of the tongue b, as shown.
The shuttle is further provided with a screw e, unto which is fitted a conical
shaped ring E¹ and resting against the spring d.
The actions of these improvements are as follows.
When the tongue is in a vertical position as is shown in Fig. II the spring c
is without any tension and lies flat, or nearly so against the tongue b, and the cop
of cotton, wool, or other weaving material is easily placed in its position on the
tongue b, thus avoiding the displacing of the layers which often happens when there
is to much of a tension on the spring c. Now if the tongue is pushed down into an
horizontal or working position the free end of the spring c comes in contact with
the rounded end of the spring d and puts a tension on the spring c which keeps the
cop firm in its place. The spring d also resting against the square end of the
tongue b, keeping the same in its proper position. The screw E with the conical
ring E is for the purpose of putting more or less tension on to the spring c
which is essential when finer or coarser yarn is used by regulating the screw E
further in it moves the spring d slightly forwards and thus puts more tension on
the spring c if screwed in the opposite direction it will reduce the tension on the
spring c.
Having now particularly described and ascertained the nature of our inven-
tion and in what manner the same is to be performed we declare that what we
claim is
I. The general construction or arrangement and combination of the parts of a

page_text: shaped opening 61 and the spring d extending into the same all substantially as
described in referring to and shown in the accompanying drawings.
II. In shuttles used for weaving the screw E with a conical ring E' or its
equivalent for regulating the tension of the tongue spring c substantially as described
in reference to and shown in the accompanying drawings.
