IMPROVEMENTS IN SHUTTLES FOR LOOMS
Year: 1884

page_text: I JAMES EARNSHAW of Whitehaven Villas Cornholme Todmorden in the County
of Lancaster Shuttle Manufacturer do hereby declare the nature of my said
invention for "IMPROVEMENTS IN SHUTTLES FOR LOOMS" to be as follows:-
This invention relates to shuttles used for looms particularly to the part known
as the tongue or spindle which carries the cop which is fitted centrally in the slot
of the shuttle.
As at present attached, to the shuttle one extremity is fitted upon a fixed pin
which is transverse to the slot of the shuttle upon which the tongue or spindle
freely works so as to be rotated for the purpose of placing the cop on the spindle
and is retained in its normal position by means of a spring.
At the part where the tongue is fitted on the pin in the shuttle as fixed at
present the shuttle is recessed to receive the extremity of tongue or spindle and it
is well known that by constant use in rotating the tongue or spindle the sides of
the shuttle or recess in contact with the extremity of the tongue easily wear,
thus creating a vacancy between the tongue or spindle and the shuttle at that part,
consequently causing an unsteadiness or unstability of the spindle with relation to
the shuttle.
My invention has for its object to obviate any irregular oscillation or unstability
of the tongue with relation to the shuttle, and consists of a steel or other suitable
metal metal bush or piece, provided with an aperture, prepared to receive a metal
or pivot inserted one in each side of the shuttle at the part suitably to connect the
tongue or spindle.
Onė extremity of the tongue or spindle is provided with a metal pin, which
has a swelled piece between its extremities and fitted into the tongue, the swelled
piece of the pin has a screw thread thereon or is plain as desired the pin is thus
screwed or otherwise fitted, thus forming a pivot on each side of the tongue and
enter into the apertures in the metal pieces or bushes between which the tongue
closely fits.
The bushes or metal pieces having their surfaces in suitable contact with the
tongue or spindle form a more durable support than provided as heretofore, and the
pin being fitted to the tongue instead of the shuttle, a more rigid condition of the
spindle is maintained within the shuttle being aided by the spring.
The manifest advantages are that the damaging of the yarn in its passage from
the cop on the spindle is obviated, consequently a great saving of expense and time
will be effected in maintaining an efficient shuttle and and dispensing with the
frequent stoppages of the loom as is the case with shuttles as heretofore constructed.
Dated this 25th day of January one thousand and eight hundred and eighty four.

I JAMES EARNSHAW of Whitehaven Villas Cornholme Todmorden in the County
of Lancaster shuttle manufacturer do hereby declare the nature of my invention
for "IMPROVEMENTS IN SHUTTLES FOR LOOMS" 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 shuttles used for looms particularly to the part known
as the tongue or spindle which carries the cop being fitted centrally in the slot of
the shuttle.
In order that my invention may be better understood I refer to the accompanying
sheet of drawings.
Fig. 1 is a longitudinal section of a shuttle at C. C. Fig 2.
Fig. 2 is a plan shewing the part where the tongue is fitted to the shuttle in
section.
Figure 3 is an end view in section at A. A. Figure 20.
Figures 46 and 11 are cross sections at B B. Figure 10 shewing my various
arrangements of attaching the tongue to the shuttle.
Figs 5. 7. 8. 9. 12. 13. 14 and 15 are parts and connections which I employ in
carrying out my various arrangements of attaching the tongue to the shuttle which
will be more particularly referred to in the following description in conjunction
with Figs 4. 6. and 11. to which they respectively belong.
My improvements consists in securing the pin D to the tongue E as shewn in
Figs 1. and 2. more particularly in Fig 11. which is drawn to a larger scale. I
also insert in the apertures F of the shuttle hollow steel or other suitable metal
bushes G. G Figs. 2. 11. 12. 13 one on each side of the tongue the same being
fitted tight on the sides of the shuttle and in contact with the sides of the head H
of the spindle stability of the spindle with relation to the shuttle is secured being
free to move in its proper direction when required for the purposes of placing the
cop thereon it is well known that by constant use the sides of the recess of the
shuttle wherein the extremity of the spindle is fitted or the sides of the head of the
spindle or the aperture through the head of the spindle casily wear in each case
manifestly causing an unsteadiness of the spindle with relation to the shuttle my
improvements are designed to obviate this and is effected by my method of securing
the Pin D to the spindle and in case that the sides of the bead H or bushes G. G¹
should wear the metal bushes G. G' may be forced or pressed against the head
thus maintaining the spindle E in a firm and central position. The bushes or:
inetal pieces having their surfaces in suitable contact with the spindle a more
durable support is provided than heretofore and again the pin being fitted to the
tongue instead of allowing the tongue to rotate on the pin as heretofore a more
rigid condition of the spindle is maintained within the shuttle being aided by the
spring I Fig 4 shews another arrangement of securing the spindle I to the shuttle
which consists of a metal pin D secured fast to the spindle having a head at
one extremity this mode of securing the spindle obviates the necessity of employing
apertures on each side of the shuttle to allow the passage of the pin the pin D is
inserted from one side a small aperture is provided on the side K which may be
used when it is desired to disengage the pin from the spindle the object of providing
the pin K suitably with a head obviates the tendency of the pin from working out.
Fig 6. shews another of my arrangements and consists of providing the metal
bushes G. G' with screw threads also providing the part of the pin D which is
fitted to the head of the spindle with a screw thread and may be operated upon

page_text: when fitting the same from the side as shewn in Fig 10. by the arrangement the
bushes G. G are firmly screwed to the shuttle and the tendency of the pin D to
disengage with the spindle obviated it is obvious that I use if desired pins secured
to the spindle having a screw thread thereon at the part where connected to the
spindle or plain as may be required.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is
First In shuttles used for weaving looms the securing of the pin to the spindle
and the use of the metal bushes substanially as and for the purposes herein set
forth and fully described.
Secondly In shuttles used for cotton looms the pin D and the metal bushes G G¹
substanially as and for the purposes herein set forth and fully described in the
various modifications of the annexed drawings.
