PROVISIONAL SPECIFICATION.
Improvements in Shuttle Action for Looms.
I, THOMAS ALBERT BRIGGS CARVER, of Heigham, Aubrey Road, Hornsey,
in the County of Middlesex, Bachelor of Science and Civil Engineer, do hereby
declare the nature of this invention to be as follows:-
My invention relates to the construction and arrangement of the shuttle driving
mechanism of a loom in such a manner as to utilise the work performed in stopping
the shuttle at the end of each stroke for aiding its propulsion in its succeeding
stroke. For this purpose, I provide at each end of the shuttle race a spring and
a detent so arranged that the shuttle, as it is being stopped, extends or compresses
the spring and is held until, by means of connections worked by a cam or its
equivalent, the spring is still farther strained and the detent is released, whereupon
the shuttle is propelled by the spring along its return stroke.
Dated this 8th day of January 1896.

I, THOMAS ALBERT BRIGGS CARVER, of Heigham, Aubrey Road, Hornsey,
in the County of Middlesex, Bachelor of Science, and Civil Engineer, do hereby
declare the nature of this invention and in what manner the same is to he
performed to be particularly described and ascertained in and by the following
statement:-
My invention relates to the construction and arrangement of the shuttle driving
mechanism of a loom in such a manner as to utilise the work performed in stopping
the shuttle at the end of each stroke for aiding its propulsion in its succeeding
stroke.
For this purpose I provide at each end of the shuttle race a spring and a detent
so arranged that the shuttle, as it is being stopped, extends or compresses the
spring and is held until, by means of connections worked by a cam or its equivalent,
the spring is still farther strained and the detent is released, whereupon the shuttle
is propelled by the spring along its return stroke.
Fig. 1 of the accompanying drawings is a side view, Fig. 2 is a sectional plan
shewing mechanism according to my invention for operating as above set forth,
Fig. 3 is a transverse section.
I mount at each side of the loom a pair of sliding rods A, B, connected rigidly
together by a crosshead C; the rod B extends from one side of the loom to the
other where it is likewise fixed to the crosshead there. The rod B in any convenient
point of its length is jointed by a pin working in a slotted hole to a lever arm D
which is moved by a cam on any convenient revolving shaft of the loom to make a
stroke to the right and to the left alternately for every pick. On each of the
rods A, B, is a helical tension spring E, having its oue end attached to a boss F
adjustable on the rods A or B, and its other end attached to a crossbead H in the

page_text: centre of which there is a disc of leather or other suitable material to receive the
blow of the shuttle. On each side of the shuttle, when it is at the end of its stroke,
there is a bar G which may be of wood or of metal faced with leather or equivalent
material, each mounted on radii M and N so as to move as a parallel ruler, and
both urged so as to close towards each other by a spring K. The two radii M
have arms projecting beyond their pivots in the path of adjustable tappets P
projecting from arms of the crosshead C.
The apparatus operates as follows:
The lever arm D being in the dotted position, the shuttle coming from the right
passes between the bars G opening them apart and strikes the crosshead H which
yields to the left extending the springs E. The shuttle is prevented from
immediately returning to the right by the parallel bars G which clamp it.
The arm D now making its stroke to the right, moves the rods A, B and their
bosses F thus farther straining the springs E, and at this movement is terminating,
the tappets P strike the projecting arms of the radii M M thus withdrawing the
clamping bars G and releasing the shuttle which is now propelled by the springs E
to the right side of the loom to be acted on there in the manner described.
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed, I declare that what I
claim is :-
Apparatus for arresting and propelling a loom shuttle, constructed and operating
substantially as described with reference to the accompanying drawings.
