TRUVIDIONAL DEPOTIVATION
Improvements in Apparatus for Doubling, Twisting, or
Spinning Silk.
We, CORNELIUS CHARLES EDGAR VAN ALSTINE, of 69 Prince Street and GEORGE
WASHINGTON GRAHAM, of 163 Graham Avenue, both in the City of Paterson, County
of Passaic, and State of New Jersey U.S.A., Manufacturers, do hereby declare the
nature of this invention to be as follows:-
The object of our present invention is to provide an apparatus, with means for
twisting the threads to furnish a finished product, and thus avoid the necessity of
subjecting the threads to the process of throwing; of simple, strong and durable
construction, reliable and efficient in operation.
The invention consists in the improved apparatus and its twisting means, and in
the combination and arrangement of the various parts thereof, substantially as will
be hereinafter more fully described.
In the accompanying drawings,
Fig. 1 represents an end elevation of an apparatus of ordinary construction, provided
with my improvements, only those parts of the doubler being shown, which are
necessary to clearly illustrate the nature of my said invention ;
Fig. 2 an enlarged detail end elevation of the right hand upper portion of Fig. 1;
Fig. 3 a detail front elevation of Fig. 2 with certain portions removed and others
broken away;
Figs. 4 and 5 are a front elevation and top plan view respectively of the twister and
its supporting reciprocating bar;
Fig. 6 an enlarged perspective view of the twister or spinner proper, and Fig. 7 a
side elevation thereof.
In said drawings a represents the frame, in which are arranged-and on each side
of the center thereof-the shafts 6 and 60, operated in the usual manner (the driving
mechanism therefor not being shown). On each of said shafts is mounted a pinion b 1
meshing into gear wheel 62, which latter is arranged on the shaft c, carrying the cam
wheel c1, by means of which the antifriction rollers c 2 are adapted to be operated.
The roller c 2 is arranged on the vertical lever c 3 fulcrumed at its lower end as at c 4,
to the frame of the machine.
The upper end of said lever is connected by means of the rod 44 to the
reciprocating bar h 5. On the shaft 60 are mounted at certain intervals a series of
friction wheels d, engaging the friction rollers d 1, which are arranged on a series
of short shafts or spindles & 2, supported in the brackets d3, arranged at right angles
to the shaft d2 and secured to the frame a in any desired manner. On each of
said shafts or spindles d 2 is secured a toothed or ratchet wheel f, adapted to be
engaged by the pawl shaped end of the lever 1, pivoted as at f2 to a projection
of the bracket frame a 2, in a manner hereinafter described.
On each of the shafts d 2, and between the friction rollers d1 is arranged a bobbin
or spool e, of the usual and well known construction.
On the reciprocating bar h 5, which is provided at certain intervals (to correspond
to the number of bobbins) with recesses 20, are secured a series of bracket plates 6,
by means of the screws 12 and 11 respectively, the latter ones penetrating elongated
radial slots h 10, arranged in their respective bracket plates. Each of said bracket

page_text: plates h6 is provided with a central groove or recess 21, in which the grooved
pulley 8 is free to revolve, which pulley is mounted on the hollow shaft h 7, having
its bearings in the said bracket plate and also in the cover 9 of the latter.
Said shaft h7 penetrates the recess 20 of the reciprocating bar 5 and projects
beyond its rear surface. The pulley h8 rests in operative position on an endless
belt passing over the horizontally arranged grooved pulleys i, operated from the
main driving shaft in any desired manner.
The bracket plate 46 is provided at its slotted end with a notch 13, engaged
by the flat spring h14, which latter tends to force the said plate against the
projection 17 of the lever 15, pivoted as at 16 and controlled by the flat
spring 18, all as clearly shown in Figs. 4 and 5 of the drawings. When the pulley / 8
is to be thrown out of engagement with the endless belt i 1, the lever h 15 is pressed
backwards by the operator, and after the bracket plate h6 has been swung upwards
on the screw 12 (serving as fulcrum), by the action of spring 14, the said lever / 15
is released, when its projection 17 engages the slot 10 and thus holds the bracket
plate and the pulley carried thereby out of operative position.
The hollow shaft 7 and its pulley h8 are provided at one side with the open
slots m3 and m 2 respectively, of a size large enough to admit the insertion of the
threads to be twisted. Said slots are capable of being brought in alignment with
the slots m 1 and m 11 arranged in and penetrating one side of the bracket plate 6
and its cover 9 respectively. On the forward end of the shatt 7, is arranged a
wire forming loop m, which loop stands substantially in the center line of the
hollow shaft and at right angles thereto. On the opposite end of said shaft is
also arranged a wire forming a loop m 10, which latter is substantially in the center
line of said shaft and in alignment therewith.
.
"
By preference the hollow shaft 7 is lined with porcelain or any other suitable
material, to prevent the threads, while passing through, from becoming bruised or
otherwise impaired. The threads t, 1
, to be twisted, pass from the
bobbins u, ul
(which latter are arranged on the bracket frame a 1 in the
usual manner) over the rod t 3, through loop 1 and over rod 2, into and through
the loop m-thence through the hollow shaft h7, loop m 10 onto the bobbin e. The
rods 2, 3 are supported in the bracket frames a 3; whilst the loop g 1 is carried
by the spring wire 9 which latter is arranged in such a manner, that when the
thread passing through its respective loop g', breaks, will drop down upon the lever f1
and thus throw the latter into engagement with one of the notches of the toothed
wheel, and thus stop the rotation of the same, and the shaft and bobbin connected
therewith.
When the wire g drops down, its rearwardly projecting arm 2 (Fig. 2) presses
against the hooked arm r1 of the angle lever, (Fig. 5) which latter is pivoted as
at 2 to the reciprocating bar h5, and bears with its other arm 3 against the pivoted
lever h 15, and thus throws said lever 15 and its pin 17 out of the path of the
frame 6. The latter by the action of the spring 1 14 (Fig. 4) is thrown upwards on
its fulcrum 12, and thus the grooved pulley 8 brought out of engagement with the
driving belt i 1, whereby the twister is stopped-simultaneously with the bobbin e.
As the hollow shaft h7 carrying the loop m-(at right angles to the center line of
said shaft) is revolved, the threads, upon passing through said loop m are twisted
together and in that form are wound upon the bobbin. When the twister is to be
threaded the slots m 3 and m 2 of the shaft 7 7 and pulley 8 are brought in alignment
with the slots m 1 and m 11 of the bracket plate 46 and 9 respectively, as will be
*** manifest.

CORNELIUS CHARLES EDGAR VAN ALSTINE, of 69 Prince Street, and GEORGE
WASHINGTON GRAHAM, of 163 Graham Avenue, both in the City of Paterson, County
of Passaic and State of New Jersey, Manufacturers, 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 :-
The object of our invention is to provide a doubler with means for twisting the
threads to furnish a finished product, and thus avoid the necessity of subjecting the
threads to the process of throwing; of simple, strong and durable construction,
reliable and efficient in operation.
The invention consists in the improved doubler and its twisting means, and in the
combination and arrangement of the various parts thereof, substantially as will be
hereinafter more fully described and finally embodied in the clauses of the claims.
In the drawings filed with the Provisional Specification,
Fig. 1 represents an end elevation of a doubler of ordinary construction, provided
with our improvements, only those parts of the doubler being shown, which are
necessary to clearly illustrate the nature of our said invention;
Fig. 2 an enlarged detail end elevation of the right hand upper portion of Fig. 1;
Fig. 3 a detail front elevation of Fig. 2 with certain portions removed and others
broken away;
Figs. 4 and 5 are a front elevation and top plan view respectively of the twister and
its supporting reciprocating bar;
Fig. 6 an enlarged perspective view of the twister or spinner proper, and Fig. 7 a
side elevation thereof..
In said drawings a represents the frame, in which are arranged and on each side
of the center thereof-the shafts b and 60 operated in the usual manner (the driving
mechanism therefor not being shown). On each of said shafts is mounted a pinion 61
meshing into gear wheel 62, which latter is arranged on the shaft c, carrying the cam
wheel c1, by means of which the anti-friction rollers c 2 are adapted to be operated.
The roller c 2 is arranged on the vertical lever c 3 fulcrumed at its lower end as at c 4,
to the frame of the machine.
.
The upper end of said lever is connected by means of the rod h4 to the
reciprocating bar h 5. On the shaft 60 are mounted at certain intervals a series of
friction wheels d, engaging the friction rollers d 1, which are arranged on a series
of short shafts or spindles d2, supported in the brackets d 3, arranged at right angles
to the shaft d 2 and secured to the frame a in any desired manner.
On each of said shafts or spindles d2 is secured a toothed or ratchet wheel f,
adapted to be engaged by the pawl shaped end of the lever f1, pivoted as at f2 to a
projection of the bracket frame a 2, in a manner hereinafter described. .
On each of the shafts d 2, and between the friction rollers d' is arranged a bobbin
or spool e, of the usual and well known construction.
'
On the reciprocating bar h 5, which is provided at certain intervals (to correspond
to the number of bobbins) with recesses 20, are secured a series of bracket plates h 6,,
by means of the screws 12 and 11 respectively, the latter ones penetrating elongated
slots 10, arranged in their respective bracket plates. Each of said bracket plates.h6
is provided with a central groove or recess 21, in which the grooved pulley h 8 is free
to revolve, which pulley is mounted on the hollow shaft h 7, having its bearings in the
said bracket plate and also in the cover 9 of the latter. Said shaft h 7 penetrates
the recess 20 of the reciprocating bar h 5 and projects beyond its rear surface. The
pulley 8 rests in operative position on an endless belt i 1 passing over the horizontally.

page_text: arranged grooved pulleys i, operated from the main driving shaft in any desired
manner.
The bracket plate 46 is provided at its slotted end with a notch 13, engaged by
the flat spring 14, which latter tends to force the said plate against the projection h 17
of the lever 15, pivoted as at h 16 and controlled by the flat spring / 18, all as clearly
shown in Figs. 4 and 5 of the drawings. When the pulley 8 is to be thrown out of
engagement with the endless belt i 1, the lever h 15 is pressed backwards by the
operator, and after the bracket plate h6 has been swung upwards on the screw h 12
(serving as fulcrum), by the action of spring h 14, the said lever h 15 is released, when
its projection 17 engages the slot / 10 and thus holds the bracket plate and the pulley
carried thereby out of operative position.
The hollow shaft h 7 and its pulley / 8 are provided at one side with the open slots m 3
and m 2 respectively, of a size large enough to admit the insertion of the threads to
be twisted. Said slots are capable of being brought in alignment with the slots m 1
and m 11 arranged in and penetrating one side of the bracket plate h6 and its
cover 9 respectively. On the forward end of the shaft, is arranged a wire forming
a loop m, which loop stands substantially in the centerline of the hollow shaft and at
right angles thereto. On the opposite end of said shaft is also arranged a wire
forming a loop m 10, which latter is substantially in the center line of said shaft
and in alignment therewith.
By preference the hollow shaft h7 is lined with porcelain or any other suitable
material, to prevent the threads, while passing through, from becoming bruised or other-
wise impaired. The threads t, t 1, . ., to be twisted, pass from the bobbins u, u 1, . .,
(which latter are arranged on the bracket frame a 1 in the usual manner) over the
rod t 2, through loop 9 1 and over rod t 3, into and through the loop m-thence through
the hollow shaft h7, loop m 10 onto the bobbin e. The rods t2, 3 are supported in the
bracket frames a 3, whilst the loop g 1 is carried by the spring wire g which latter is
arranged in such a manner, that when the thread passing through its respective
loop g, breaks, will drop down upon the lever f1 and thus throw the latter into
engagement with one of the notches of the toothed wheel f, and thus stop the rotation
of the same, and of the shaft and bobbin connected therewith.
When the wire g drops down, its rearwardly projecting arm g 2 (Fig. 2) presses
against the hooked arm 1 of the angle lever r (Fig. 5) which latter is pivoted as at r 2
to the reciprocating bar 5, and bears with its other arm r3 against the pivoted
lever h 15, and thus throws said lever / 15 and its pin h 17 out of the path of the frame h 6.
The latter by the action of the spring 14 (Fig. 4) is thrown upwards on its
fulcrum h12, and thus the grooved pulley 8 brought out of engagement with the
driving belt i 1, whereby the twister is stopped-simultaneously with the bobbin e.
As the hollow shaft h7 carrying the loop m-(at right angles to the centerline of
said shaft) is revolved, the threads, upon passing through said loop m are twisted
together and in that form are wound upon the bobbin. When the twister is to be
threaded the slots m 3 and m 2 of the shaft h 7 and pulley h8 are brought in alignment
with the slots m 1 and m 11 of the bracket plates h6 and h 9 respectively, as will be
manifest.
We do not intend to limit ourselves to the precise construction shown and
