Year: 1883

of Worcester, Mechanic. for an Invention of "AN IMPROVED LOOM-SHUTTLE"
PROVISIONAL SPECIFICATION left by the said William Youngjohns at the
Office of the Commissioners of Patents on the 25th September 1883.
WILLIAM YOUNGJOHNS, of Kidderminster, in the County of Worcester,. Mechanic,
"AN IMPROVED LOOM-SHUTTLE"
My invention relates to an improved shuttle for use in looms for weaving
carpets or other fabrics
Heretofore shuttles of this kind have generally been made of wood which is
liable to crack or split. And although, in some instances, shuttles have been made
of malleable cast iron their use has not been practicable by reason of their liability
to injure the weft when it is thrown across the shuttle-race
My invention is designed to obviate this defect and thus enable shuttles-made
of malleable cast iron or other suitable metal to be advantageously employed in
place of the wooden shuttles at present in use
In carrying my said invention into practise I make the body of the shuttle of
iron or other suitable metal and secure to its underside a strip of wood or other
material that will not injure the weft. I prefer to make the shuttle of malleablé
cast iron and to form a recess or groove in its underside, in which recess or groove
I fit the strip or piece of wood or other material. This strip or piece should
extend from end to end of the shuttle, or nearly so, and may, if desired, be of
the same width as the metal; the said piece is secured by rivets or other suitable
means.

WILLIAM YOUNGJOHNS of Kidderminster, in the County of Worcester, Mechanic.
"AN IMPROVED LOOM-SHUTTLE"
My invention relates to an improved shuttle for use in looms for weaving carpets
or other fabrics.
Heretofore shuttles for this purpose have generally been made of wood; these
shuttles, although very advantageous as regards their working, are liable to crack
or split long before they are worn out. To obviate this inconvenience, attempts
have been made to employ shuttles made of malleable cast iron, but their use has
been found to be impracticable by reason of their liability to injure the weft as it
is thrown across the shuttle-race.
My invention is designed to construct an improved shuttle which will combine
the advantages of the wooden shuttle as regards its working with those of the iron
shuttle as regards its durability. For this purpose I make the body of the shuttle
of iron or other suitable metal and provide the same on its underside with a strip
or piece of wood or other material that will not injure the weft.
I prefer to make the body of my improved shuttle of malleable cast iron and to
form a recess or groove in its underside, in which recess or groove I fit the strip
or piece of wood or other material. This strip or piece should extend from end
to end of the shuttle, or nearly so, and may, if desired, be of the same width as
the metal, and may be secured to the body of the shuttle by rivets or other
suitable means.
My said invention may be conveniently and advantageously carried into practice
in the manner illustrated in the accompanying drawing, in which
Figure 1 is an inverted plan, and
Figure 2 a transverse section of one form of my improved shuttle.
Figure 3 is a side elevation, and
Figure 4 a transverse section of another form or modification thereof.
a indicates the body of the shuttle, which is made of iron or other suitable
metal, b indicates the strip or piece of wood or other material, and c the rivets for
securing the said strip or piece to the body a.
In the shuttle shown in Figures 1 and 2, the strip or piece b is fitted tightly in
a longitudinal recess or groove a¹ in the body a, but in the shuttle shewn in
Figures 3 and 4 the said strip or piece extends entirely across the body a and
forms the base of the shuttle. The usual longitudinal groove b' is formed in the
bottom of the shuttle to permit the passage of the weft beneath it.
Having thus fully described my said invention and the manner of performing
the same I wish it understood that I claim :-
:-
A shuttle having a strip or piece of wood or other suitable material combined
with a metal body, substantially as, and for the purpose, above specified.
In witness whereof I the said William Youngjohns have hereunto set my
hand and seal this twenty-fifth day of March in the year of our Lord One
thousand eight hundred and eighty four.
WILLIAM. YOUNGJOHNS (L.S.)
