PROVISIONAL, SPECIFICATION left by the said Alfred Vincent Newton
at the Office of the Commissioners of Patents, with his Petition,
on the 3rd April 1873.
I, ALFRED VINCENT NEWTON, of the Office for Patents, 66, Chancery
5 Lane, in the County of Middlesex, Mechanical Draughtsman, do hereby
declare the nature of the said Invention for "AN IMPROVED SHUTTLE
MOTION FOR Looms," to be as follows:-
This Invention, which is more particularly designed to be applied to
narrow ware looms, consists in a novel construction and arrangement of

page_text: the shuttle operating mechanism, whereby, among other advantages,
provision is made for a very rapid motion.
In carrying out the Invention the loom may be constructed and
organized to weave several webs at the same time, as is common with
narrow ware looms, but it is proposed generally with a view to running
at greater speed to construct and organize looms with the Invention so
that each loom shall weave only a single web. In any case, however,
the raceway and shuttle motion will be provided entirely separate and
distinct for the weaving of each web and will be the same either in a
loom for weaving a single web, or in one for weaving two or more
webs together, in the latter case merely requiring to be duplicated or
multiplied according to the number of webs to be woven.
'
The shuttle consists of a thin flat frame, the sides of which are curved
to correspond with a segment-shaped raceway. This raceway is formed
in a flat plate, through the centre of which works a boss that receives a
reciprocating motion from a cam on the cam shaft of the loom for the
purpose of driving the shuttle. The sides of the shuttle are provided
with flanges which work in grooves formed in the sides of the raceway.
Near the opposite ends of the shuttle its inner side is notched or re-
cessed to receive the ends of two fingers or drivers which are carried by
the boss before mentioned, and are free to slide endwise therein. These
drivers cross each other in the central boss to allow of their engaging
with the shuttle outside of the shed, and their rear ends are fitted with
these
bowles which enter a cam groove made in the race plate. So long as
bowles, one or both, remain in the main or concentric portions of the
cam groove their drivers will engage with the shuttle, but as one or other
bowle enters an offset of this groove its driver will be released from the
shuttle, thus leaving it free to pass through the open shed. An opening
is made in the ráce plate from the front edge thereof to a point in the
rear of the raceway wide enough for the free passage of the warp. and
for the lay for beating up the work.

WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Third day of April, in the year of
our Lord One thousand eight hundred and seventy-three, in the
thirty-sixth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Alfred Vincent, Newton, Her special
licence that I, the said Alfred Vincent Newton, my executors, ad-
ministrators, and assigns, or such others as I, the said Alfred Vincent
Newton, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times thereafter
during the term therein expressed, should and lawfully might makė,
'use, exercise, and vend, within the United Kingdom of Great Britain
and Ireland, the Channel Islands, and Isle of Man, an Invention for
"AN IMPROVED SHUTTLE MOTION FOR LOOMS;" being a communication to
me from abroad by Charles Irwin Kane, of Milford, in the State of
Connecticut, United States of America, upon the condition (amongst
others) that I, the said Alfred Vincent Newton, my executors or
administrators, by an instrument in writing under my, or their, or one
of their hands and seals, should particularly describe and ascertain the
nature of the said Invention, and in what manner the same was to
be performed, and cause the same to be filed in the Great Seal Patent
Office on or before the Fourteenth day of October One thousand eight
hundred and seventy-three.
NOW KNOW YE, that I, the said Alfred Vincent Newton, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement, reference being had to the Drawing hereunto
annexed, and to the letters and figures marked thereon (that is to say):
This Invention, which is more particularly designed to be applied to
narrow. ware looms, consists generally in a novel construction and

page_text: arrangement of the shuttle operating mechanism, whereby, among other
advantages, provision is made for a very rapid motion.
In carrying out the Invention the loom may be constructed and
organized to weave several webs at the same time as is common with
narrow.ware looms, but it is proposed generally with a view to running
at greater speed to construct and organize looms with the Invention, so
that each loom shall weave only a single web. In any case, however,
the raceways and shuttle motion will be provided entirely separate and
distinct for the weaving of each web, and will be the same either in
a loom for weaving a single web; or in one for weaving two or more
webs together, in the latter case, merely requiring to be duplicated or
multiplied according to the number of webs to be woven.
Having thus specified the object and nature of the Invention its.
description will be proceeded with in reference to the accompanying
Drawings.
Fig 1 represents an irregular, vertical, longitudinal section of a.
narrow ware loom having the improvements applied; Fig. 2, a top view
of the shuttle race and shuttle; Fig. 3, an under view of the same,
showing also the shuttle driving mechanism; and Fig. 4, a section
at the line x, x, in Fig. 2. Similar letters of reference indicate
'corresponding parts.
•
In these Figures A is the raceway in which the shuttle B works.
This raceway is segment-shaped, and its plane is parallel or nearly so
with that in which the web C is woven, and perpendicular to the harness
motion D: Said raceway, which is stationary for use in combination
with a lay or beater E,. having a reciprocating motion, is made entirely
open above and below and with the bearing surfaces b, b, of the shuttle
formed by grooves and rebates in opposite lines in a plane parallel with
that in which the web is woven, or perpendicular to the harness motion.
In the outer edge of the raceway there is an opening c, c, wide enough
for the free passage of the warp w.
The shuttle consists of a thin flat frame, the two sides of which are
curved to correspond with the bearing surfaces b, b, its ends being of a
straight or other form. The side which works in the inner bearing 6
has guides or slots u, u, in its under surface to receive the shuttle
driver or fingers G, G, and said side is preferably arranged to project
slightly beyond the other parts of the ends of the shuttle frame to

page_text: facilitate the entrance of the shuttle into the warp. The bobbin F,
which carries the weft, is arranged lengthwise of the shuttle to work in
close proximity to the outer circle of the raceway. Parallel with the
bobbin is a wire or rod d, round which the yarn is wound to produce
upon it the necessary friction and tension as it passes from the bobbin
to the eye e, which is arranged at the centre of the length of that
side nearest the inner circle of the raceway. To the shuttle frame
also is attached a friction spring f, which presses upon the yarn on the
bobbin.
The fingers or drivers G, G, consist of two flat rods, which pass across
each other through straight guides or grooves provided for their
reception in a disc or boss H which works in a bearing in the raceway
plate I, said disc or boss being concentric with the curved raceway:
The boss H has imparted to it an oscillating motion by which the
fingers G, G, being carried back and forth with a circular motion
by the boss are caused to impart to the shuttle the necessary motion in
the raceway. In the under side of the plate I, or in a plate secured
thereto is a stationary cam-like groove h, h, i, shewn in Fig. 3, the
portions h, h, being corresponding arcs of circles concentric with the
raceway and shuttle driving boss H, and united by an offset i. The
fingers G, G, are each furnished with an antifriction roll k, which is
received within the cam groove, and which run therein as the fingers
oscillate with the boss H. As the rolls pass into and from the offset i
of the groove they produce longitudinal movements of their respective
fingers G, by which the latter are alternately withdrawn from and
caused to re-enter within their respective guides or slots u, u, such move-
ments taking place at the proper time to withdraw each finger in turn
from the shuttle in time to prevent. it from coming in contact with the
warp, and to keep it out of contact during a suitable portion of its
oscillating motion to prevent its interference with the passage of the
shuttle, one finger G at least being always in operation in the shuttle.
The boss H carrying the fingers or shuttle drivers G, G, may have its
oscillating motion imparted to it by any suitable means, as, for instance,
by an arm m and rod 1, operated by a lever K having its fulcrum at n,
and gearing by a stud o with a revolving grooved wheel or cam L.
Opposite to and in line with the opening c, c, in the raceway is a recess r
for the entrance of the lay or beater E, which passes through the
opening c, c, crosses the stationary raceway and enters the said recess r
to beat up the filling.

page_text: The harness D of the loom is intended to be arranged in a vertical
position as near to the end S of the plate I as is practicable, allowing
room for the lay or beater which works in front of it to pass back as
far as is necessary from the raceway.
Having now set forth the nature of the Invention of "An Improved
Shuttle Motion for Looms," as communicated to me by my foreign
correspondent, and explained the manner of carrying the same into
effect, I wish it to be understood that under the above in part recited
Letters Patent I claim,-
First. The oscillating and longitudinally sliding shuttle fingers or
drivers G, G, arranged in relation with each other, and with a segment-
shaped raceway for operation in combination with a curvilinearly
reciprocating shuttle, substantially as specified.
Second. The combination of the curvilinearly reciprocating shuttle B
provided with slots or guides u, u, on its inner side, the segment-shaped 1
raceway A open above, and below, and the oscillating and longitudinally
sliding shuttle fingers or drivers G, G, the whole being arranged for
operation in relation with each other and with the warp, essentially as
shewn and described.
In witness whereof, I, the said Alfred Vincent Newton, have 2
hereunto set my hand and seal, the Third day of October, in
the year of our Lord One thousand eight hundred and seventy-
