Improvements in Loom Shuttles and Tongues.
I ABRAHAM Woon of 55 Bridge Street, Ramsbottom, in the County of
Lancaster, Jeweller, do hereby declare the nature of this invention to be as
follows:-
My said invention relates to improvements in the manufacture of loom shuttles
and in the mounting and supporting of the tongues thereof. According to my
invention I construct the shuttle from thin sheet steel or from other sufficiently
light, strong and malleable metal capable of being pressed or stamped to the
requisite shape. At present I am of opinion that thin sheet steel is the most
suitable for my invention. In carrying out my improved manufacture I press or
stamp a strip or portion of sheet steel by means of suitably formed matrices or
moulds into a shape or form equivalent or corresponding to one half or side of a
shuttle and by similar means press or shape the other half. I then braize the
two halves together, thus forming a complete hollow metallic shuttle. The tips of
the shuttle might be formed from the material of the shuttle itself or I might
braize or otherwise secure solid tip points to the shuttle ends. The shuttle tongue
is formed with a flat sheet metal butt which may be folded on itself so as to lap
over and embrace the cross pin upon which it is pivotted or the upper portion may
be braized or rivetted to the said flat butt. The tail of the shuttle tougue butt is
formed with a projection which works in contact with a flat spring secured to the
inner side of the hollow metallic shuttle. A perforation or recess is formed in
the said flat spring and when the tongue is lying within the shuttle in its proper
normal position the projection from the butt snaps into this recess or perforation in
the spring, so that the tongue is held securely in its normal position. To raise the
tongue into a position which will admit of the cop being placed thereon I press the
flat spring towards the side of the shuttle and so release the projection on the butt
from the recess. The tongue can then be turned upon its pivot and the sidelong
pressure of the spring on the projection holds the tongue at any position into which
it may be turned. The said spring might be on one or on both sides. The bosses
to receive the pivot pin may be separately braized to the inner sides of the shuttle
or they may be made in one with a cross piece which would be secured within the
shuttle. When such a cross piece is used it serves as a cross stop to prevent the
shuttle tongue from being turned down beyond a certain point. The pivot pin is
inserted from the outside and is fixed by a pin driven through the butt and through
the pin. The pivot may be dislodged and driven out through a smaller hole on the
opposite side of the shuttle.
The eye through which the yarn is led from the cop through the side of the
shuttle may be formed by curling over one corner of a stay piece fixed across the
interior of the shuttle at the leading end.
The advantages of such a shuttle as I have described are many. It may be no
heavier and might be made lighter than the wooden shuttle. In prime cost it
compares favourably with the wooden shuttle and lasts a much longer time. It
does not warp, twist or split like the wooden shuttle and travels over the
ends with greatly less friction and with less risk of breaking and cutting
the ends.

page_text: The light thin material of which my improved shuttle is made leaves much more
space in the interior of the shuttle and enables a much bulkier cop to be placed on
the tongue.
Although as already said 1 at present consider thin sheet steel to be
the most suitable material from which to make my improved shuttle, any other
sufficiently light, strong and malleable metal might be used.

improvements in Loom Shuttles and longues.
I ABRAHAM WOOD. of 15 Bridge Street, Ramsbottom, in the County of
Jancaster, Jeweller, 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 and accompanying drawings:-
My said invention relates to improvements in the manufacture of loom shuttles
and in the mounting and supporting of the tongues thereof. According to my
invention I construct the shuttle from thin sheet steel or from other sufficiently
light, strong and malleable metal capable of being pressed or stamped to the
requisite shape. At present I am of opinion that thin sheet steel is the most
suitable for my invention.
My invention will be best understood by a reference to the annexed sheet of
illustrative drawings.
Fig. 1 shows the two separate stamped halves A and B of the shuttle.
Fig. 2 shows the said two separate halves in cross section.
Fig. 3 shows the complete shuttle formed of the two halves A, B braized
together and fitted with eye and shuttle tongue.
Fig. 4 is a longitudinal section of Fig. 3.
Figs. 5 and 6 illustrate the spring tongue.
Fig. 7 shows the bearings and spring for the tongue.
In carrying out my improved manufacture I press or stamp a strip or portion of
sheet steel by means of suitably formed matrices or moulds into a shape or form
equivalent or corresponding to one half or side A of a shuttle and by similar means
I press or shape the other half B. These two sections are shown lying side by side
and separate in Figs. 1 and 2. I then braize the two halves A, B together, thus
forming the complete hollow metallic shuttle shown in Figs. 3 and 4.
The tips C of the shuttle might be formed from the material of the shuttle
itself, but I prefer to braize or otherwise secure solid tip points C to or in the
shuttle ends. When this is done I form orifices at the shuttle ends to receive the
said tips C. The tips are formed as most clearly shown in Fig. 4, the tip being
checked midway so as to present a shoulder C. When the two halves of the
shuttle are put together, the halves clip the tips at the checked portion, so that
the tips are securely held, the checked shoulder preventing shifting in one direction
and the inclined portion in the other direction. The shuttle tongue D is also
stamped from thin sheet steel, and is formed with a flat sheet metal butt D' which
may be folded on itself so as to lap over and embrace the cross pivot pin E upon
which it is pivotted, but I prefer that the upper portion D² should be braized or
rivetted to the said flat butt D¹.
By prolonging the front end of the upper portion D2 and causing it to overhang
as clearly shown in Fig. 4 a recess is formed to receive the free end of the spring D³
which is thus boxed in and shielded. The end of the shuttle tongue butt is formed
with a projection D³ which works in contact with a flat spring F secured to the

page_text: inner side of the hollow metallic shuttle by means of rivets as shown. A perforation
or recess F1 (see Fig. 7) is formed in the said flat spring F and when the tongue D
is lying within the shuttle in its proper normal position (as shown for example in
Fig. 4) the projection D³ from the butt snaps into this recess or perforation F¹ in
the spring F so that the tongue is held securely in its normal position. To raise
the tongue into a position which will admit of the cop being placed thereon, such a
position for instance as is indicated in Fig. 7 of the drawings,
press the flat
spring F towards the side of the shuttle and so release the projection D³ on the
butt from the recess F¹. To facilitate this pressing aside of the spring F I form
it with a thumb piece or curl F2 upon which the thumb is placed to push the spring
to one side. The tongue D can then be turned up on its pivot and the sidelong
pressure of the spring F on the projection D³ holds the tongue at any position into
which it may be turned. A cross pin H prevents the tongue from being turned
round further than into the vertical position shown in Fig. 7. The said spring
might be on one or on both sides in which latter case the projection D³ is also on
both sides as shown in Fig. 5.
The bearing bosses G to receive the pivot pin E, which carries the tongue, may
be separately braized to the inner sides of the shuttle but preferably they are made
in one with a cross piece G¹ which is secured within the shuttle by braizing. In
fixing this cross piece I let the ends or one of the ends project through the sides of
When the
the shuttle, so that when braized in position it remains very secure.
cross piece G¹ is used, it serves as a cross stop for the shuttle tongue butt D' and
prevents the shuttle tongue from being turned down beyond a certain point, viz.
beyond the horizontal position shown in Fig. 4. The pivot pin E is inserted from
the outside through the bearing bosses G and is fixed by a pin I driven through
the eye of the butt and through the pin E. The pivot may be dislodged and driven
out through a smaller hole on the opposite side of the shuttle. The eye of the
butt D is formed with semi-circular wings D' which project over the bearing
bosses. The eye through which the yarn is led from the cop on the shuttle tongue D
through the side of the shuttle, may be formed by curling over one corner of a
stay piece K fixed across the interior of the shuttle at the leading end as plainly
shown in Figs. 3 and 4. The ends of the eye piece K may project through the
sides of the shuttle as in the case of the cross piece G¹ for the purpose of giving it
a more secure hold. As the lower side of the shuttle might in course of time wear
away, I could if thought desirable make the shuttle in the first instance with a
removable shoe or sole secured to the under side of the shuttle and capable of
being renewed when it became worn. This removable shoe or sole is illustrated in
the sectional view Fig. 8. The shuttle is made without the flat ledge on each side
of the underside, and I make the separate sole L, with upturned side flanges L'
which slip inside of the hollow shuttle and are braized to the shuttle sides.
Although I have described my improved shuttle as composed of two stamped
halves braized longitudinally together, it is nevertheless to be understood that
although I think this to be the most practicable form of construction, such a
shuttle might be dished or pressed from metal in two halves or ends to be braized.
together with a cross or diagonal joint. I might also in some cases make the
shuttle from more than two parts.
The advantages of such a shuttle as I have described are many. It may be no
heavier and might be made lighter than the ordinary wooden shuttle. In prime
cost it compares favourably with the wooden shuttle and lasts a much longer time.
It does not warp, twist or split like the wooden shuttle and travels over the ends
with greatly less friction and with less risk of breaking and cutting the ends. The
light, thin material of which my improved shuttle is made, leaves much more space
in the interior of the shuttle and enables a much bulkier cop to be placed on the
tongue. Although as already said I at present consider thin sheet steel to be the
most suitable material from which to make my improved shuttle, any other
sufficiently light, strong and malleable metal might be used.
