Improvements in Swivel-shuttle Looms for Weaving.
I, HENRY BERNOULLI BARLOW, of 17 St. Ann's Square, Manchester, in the
County of Lancaster, Patent Agent, do hereby declare the nature of this inven-
tion which has been communicated to me from abroad by Otto Walter Schaum, of
2260 North Eighteenth Street, Philadelphia, Pennsylvania, one of the United
States of America, Manufacturer of Textile Machinery, 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 swivel shuttle-looms and has for its object to provide
an improved construction of the carrier blocks which hold the shuttles and an
improved mode of attaching such blocks to the swivel batten beam.
Much difficulty has heretofore been met with in looms of the character referred
to in getting at the swivel shuttles in order to remove them or the blocks containing
them from the beam or to replace the bobbins in the shuttles. This present inven-
tion consists in securing the carrier block to the beam by means of clamping
plates hinged together so that each block can be readily turned up. from a position
beneath the supporting beam to one alongside of it without detaching it from the
beam. Preferably I attach a spring to the hinge, arranging it to throw the block
out from the beam. It further consists in the particular way in which a number
of parts making up the carrying block are secured together to form such block
and it will be understood that, save in certain details of construction this present
invention is applicable to single shuttle blocks as well as to those carrying two or
more as shown in the drawings. Reference being now had to the drawings which
illustrate this invention, and in which,
Figure 1 is a side elevation of a portion of a loom illustrating the position of the
swivel shuttles with respect to the reeds and shed.
Figure 2 is a front view of the swivel batten beam with the attached shuttle-
carrying blocks.
Figure 3 is an end view of a portion of the beam and block attached thereto.
Figure 4 a cross-sectional view taken on the line 1-2 of Figure 3 and showing
in dotted lines the position to which the shuttle-carrying block can be thrown by
the spring.
Figure 5 is a cross-sectional view on the line 3-4 of Figure 4 drawn to a some-
what larger scale; and
Figure 6 a sectional view taken on the line 5-6 of Figure 4.
A is the frame of the loom; B the lay; C the warp beam; D the take-up roll;
E the shed; F the reeds; G is the swivel-batten beam which, in practice, is moved
at proper intervals vertically, or vertically and horizontally; the mechanism for
actuating the beam forming no part of this invention I have not thought it necessary
to illustrate it. HH H, etc., are the shuttle-carrying blocks, which in operative
position, are secured at regular intervals along the bottom of the beam G as shown
in Figure 2. 1 secure the said blocks to one side of the beam by means of clamping-
plates Land L' united by the hinge L' so that the block with its contained shuttles
can be thrown from the position shown in full lines in Figure 4 to the position
shown in dotted lines in the same figure or to an intermediate position; it will be
understood that each carrier-block is independently hinged to the beam. The
block may be held in operative position by any convenient means; thus, a catch N
pivoted on the opposite side of the beam G to that on which the hinged clamp is
secured can be advantageously made to engage a latch pin M on the block; a
light spring N' holding the pivoted catch in position and the upper end of the
catch projecting above the beam so that it can be made to release its hold upon

page_text: the block by a light pressure of the finger (see Figure 3). It is sometimes advisable
to provide a catch as shown at R (Fig. 4) to catch and hold the block when turned
away from the beam; a spring S however, arranged to throw the block out from
the beam when released by catch N will answer all necessary purposes. In the
bottom of the block H are grooves formed by planing out longitudinal slots in
the bottoms of the parts which make up the block, into which grooves extend the
shanks O of the shuttles O; the tops of these shanks support or are formed into
racks O¹ which engage with pinions I pivoted in the blocks and extending above
the tops thereof so as to engage rack bars G¹ moving in grooves at the bottom of
the beam G. Pinions I are arranged in the block so as to engage each shuttle.
In the above features of construction the blocks are generally similar to those
which have heretofore been used but in the special features of construction
which I am about to describe the blocks shown in the drawings are, I believe,
new with me.
I form each block of a series of parts or plates as H¹ H³ H³, etc., (see Fig. 5);
two parts being used for a single shuttle carrier block, three for a double shuttle
block, and so on. On the abutting faces of the parts making up the block I form
circular grooves or depressions of a size sufficient to receive pinions of the desired
thickness, said depressions being concentric with parallel transverse perforations h
which are formed through each part so as to register with the perforations in the
abutting parts. The pinions being placed in position in the circular depressions
formed to receive them, and the parts H¹ H2 etc., being placed together, a hollow
tube J is passed through the perforations in the parts of the block and through
the centre of the pinion wheels for which it serves as an axle or bearing. The
parts having been assembled are then secured together preferably as shown in
Figure 5, by means of screw-bolts K which pass through the tubes J and the
threaded ends k of which screw into a plate or plates on the outside of the block;
preferably they screw into threaded perforations / formed in the part L of the
hinged plates L L'
In order to bring the centres of the wheels or pinions I closer together or, in
other words, to shorten the length of the carrier blocks, it is convenient to stagger
the two pinion wheels upon each swivel shuttle and where this construction is
adopted form in the face or faces of each of the separate parts of the carrier
block, first, a circular depression large enough to receive the pinion I, said
depression being concentric with one of the transverse perforations; while about
the other perforation I form the circular depression of a size which will fit
neatly about a hub extension I which I form on each pinion wheel; in this way
each pinion I is centered not only by the tubular bearing upon which it rests but
also by the bearing of its hub extension I¹ on the circular depression /².
Having now particularly described and ascertained the nature of this said inven-
tion, and in what manner the same is to be performed, 1 declare that what I
claim is :-
First: The combination of the beam G with separate and independent swivel-
shuttle-carrying blocks H arranged to carry the swivel shuttles and hinged clamps
connecting them to the beam, all substantially as described and so that the blocks
can be thrown up to the side of the beam.
Second: The combination of the beam G with swivel-shuttle-carrying blocks H
arranged to carry the swivel shuttles; hinged clamps connecting said blocks to
the beam, and springs arranged to hold the blocks normally to the beam while
permitting them to be turned out from it, all substantially as described, and so
that the blocks can be thrown up to the side of the beam.
Third: The combination of the beam G with swivel-shuttle-carrying blocks H
arranged to carry swivel shuttles, hinged clamps L L' connecting the blocks to
one side of the beam and a catch arranged to engage and hold the blocks on the
opposite face of said beam substantially as specified.
Fourth: The combination of the beam G with swivel-shuttle-carrying blocks H

page_text: arranged to carry swivel shuttles, hinged clamps L L' connecting the blocks to one
side of the beam and a catch R arranged to catch and hold block away from the
beam, substantially as specified.
Fifth: A swivel-shuttle-carrying block H made up of two or more parts grooved
on their abutting faces to receive pinions I and on their bottoms to form grooves h*,
in combination with transverse bearing rods running through the sections
substantially as specified.
Sixth: A swivel-shuttle-carrying block H consisting of two or more parts
grooved on their abutting faces to receive pinions between them and on their
bottoms to form grooves, in combination with tubes J passing through said
blocks, pinions I journaled on said tubes and situated in the grooves of the blocks,
and binding bolts K extending through tubes J and arranged to clamp the parts of
the blocks together, substantially as specified.
Seventh A swivel-shuttle-carrying block H consisting of two or more parts
grooved to receive pinions between them in combination with tubes J passing
through said blocks, pinions I journaled on said tubes, and situated in the grooves
of the blocks and bearing rods extending through said tubes substantially as
specified.
Eighth A block H made up of a series of parts H₁ H' etc., said parts having
parallel registering perforations hand on one or both faces a circular depression h¹
concentric with one transverse perforation and of a size to receive a pinion I and
a circular depression * concentric with the other transverse perforation and of a
size to receive the hub I' of a pinion in combination with staggered pinious I
having hubs I', tubes J passing through perforations h and serving as bearings for
the pinions, and clamping bolts K arranged to clamp and hold the parts of the block
together.
