Improvements in Take-up Devices for Looms.
I. ALLEN LEVI SKINNER, of No. 41 Osgood Street, in the City of Springfield,
County of Hampden and State of Massachusetts, United States of America,
Mechanical Engineer, 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 :-
This invention relates to improvements in take-up mechanism for looms, one
object thereof being to provide improved mechanism intervening between the lay-
frame and the take-up or cloth-beam whereby the rotary movement of the cloth-beam
is caused to be exactly coincident with the movement of the woven fabric, whatever
may be the number of picks therein per inch. A second object being to provide
for setting the cloth-beam operating mechanism, when the warp is put into the
loom, to correspond with the number of picks to be woven therein, and indicating
devices in sight of an inspector showing plaiuly what number of picks the take-up
mechanism is set to. A third object, is to provide mechanism for limiting back-
turn of the cloth-beam caused by the warp-strain when the loom is stopped, and
determining the degree of said back-turn according to the requirements of cloth
being woven, to the end that upon starting up the loom again, the first pick made
shall be in proper position relative to the preceding pick, all as hereinafter fully
described, and more particularly pointed out in the claims.
Reference is had to the accompanying drawings forming part of this Specification,
in which-
Figure 1 is an elevation of a portion of the end of a loom, having my improve-
ments applied thereto; this figure illustrating a lever on the end of the stop-motion
rock-shaft of the loom, in proximity to beam rotating mechanism, the purpose of
which is below described.
Figure 2 is similar view of the end of a loom to that shown in Figure 1,
illustrating in connection therewith features of the improvements not shown in
Figure 1, and showing portions of the latter in dotted lines, and a part of the gear
on the end of the cloth-beam shaft.
Figures 3 to 9, inclusive, illustrate detail parts which are fully described below.
In the drawing, A is a part of the frame of the loom at one end thereof.
B indicates the lay-frame carried upon a horizontal shaft d, in the usual manner.
C is a radial arm, also secured ou shaft d, and said arm is formed with a
longitudinal slot therein centrally between its edges. Thus the arm C, moves in
consonance with the lay-frame. A bolt-like arm D, (see Figure 5) having a
nut 14, formed therein whose sides are flattened, as shown, is inserted through said
arm C, in a position to have a sliding motion within said slot, the said flattened
side of nut 14, bearing against the borders of said slot. A screw-rod E, is passed
through the upper extremity of said radial arm C, and through the said nut 14.
A collar e,
is fixed on said screw-rod at the upper end of said slot and thus while
said rod may have a free rotary motion it is prevented from end wise movement.
The said bolt-like arm extends somewhat beyond the front face of said arm C, and
extends rearwardly beyond said arın.
On the outer end of the bolt-like arm D, is a loose pulley F, having a hub F2,
thereon, said pulley having a free rotary motion on said bolt. On the said hub F
is secured a pointer or hand 9, (see Figures 1 and 2) which rotates with said pulley.
Between said pointer and pulley is placed a dial G, having ribs 14*, on its rear

page_text: side (see Figure 9 which is a sectional view of said dial about on line -x, on said
figure) by which it has such engagement with the edges of the arm C, as prevents
it from rotation, but permits it to slide up and down on the face of said arm
carried by the bolt-like-arm D, when the latter is actuated to move up and down
by turning the said screw-bolt E. Two metal, strips or ribbons f, are secured each
by one end at 2, (Figure 5) on the periphery of the said pulley F, each strip being
wound thereon in opposite directions, one extending, as shown, and being secured
to the upper end, and one to near the lower end of said arm C, as shown in
Figures 1 and 2, to the end that when said pulley is carried up or down on said
bolt D, the said pulley and the hand g, are rotated thereby causing said hand to
indicate by the position of the said bolt D, within the slot in said arm, a certain
number of vibratory movements of the lay-frame, or the number of picks woven in
a given length of fabric. Graduation marks are shown on said dial in Figures 1
and 2, to a certain extent, on its face, to indicate the movement of said hand, 9,
and the number of picks, as aforesaid.
The said screw-rod E, has fixed on its upper end a hand-wheel H, whereby said
screw-rod is turned.
The said bolt-like armi D, extends beyond the rear side of the vibrating arm C,
and its rear end enters the horizontal arm of a tubular elbow h.
A lever I, having a cylindrical lower end which enters the vertical arm of said
elbow h, and has a free sliding movement therein, has on its upper end a hub as
shown, projecting upwardly from which are two flat bosses, 15 and 16. (Said
bosses are not shown in Figure 2.)
A shaft K, is supported in a bearing in the frame A, (see Figure 6) and said
lever I, is hung on the end of said shaft and swinging thereon, actuated by the
said vibratory movement of the arm C. A collar 17, retains the hub of said lever
on shaft K.
A pulley k, is secured on shaft K, and has an intermittent rotary movement. The
inner surface of the rim of said pulley, each side of the arms thereof, is finished to
true circle.
A bracket L, (see Figure 6) having a long journal-box m, on its upper end, is
secured to frame A.
The said shaft K, passes through said journal-box m, and has a pinion M,
secured to its rear end. The said pinion M, (see Figure 2) engages with a gear W,
which is fixed on the end of the shaft X, of the cloth-beam of the loom. Directly
back of said pulley k, is a disk N, which is secured on said long journal-box m,
by a set screw 2, or other suitable means, said disk having a circular rib 18, at one
edge of its periphery (see Figures 6 and 7). At the opposite edge of its periphery,
said disk N, has several pins n, inserted therein, which, together with said rib,
serve to retain a ring S, thereon, said ring being adapted to have reciprocating
rotary movement on said disk. A lever R, extends from the upper edge of the
ring S, and on the opposite edge thereof is an arm 19, in which is fixed a forwardly
projecting pin t, and on the rear side of lever R, just above said ring, is a second
pin t, (see Figure 1). Said lever R, also has thereon a hook t, extending over
the face of pulley K, and having its extremity bent inwardly toward said lever.
On said lever 1, on the boss 16, thereon, is hung the arm J, on the extremity of
which is pivotally hung a friction driving shoe j. Said arm J, constitutes a
toggle connection between said lever I, and shoe j. A spring 1, one end of which is
fixed to the inner side of the boss 15, on lever 1, and coiled around a stud ou said
arm, has its free end hooked into a hole in an arm 20, on said arm J, and said
spring acts to hold the friction shoej, uormally in contact with the surface of
pulley k, on which it bears. The relation of said arm J, and shoe j, to the lever I,
is such as clearly shown in Figure 1, that when arm C, swings from the position
shown in Figure 2, to that shown in Figure 1, said shoe, by its said toggle
connection with lever I, through arm J, as described, is forced against the rim of
pulley k, and the latter is caused to turu more or less. Said shoe j, is retracted
irom said pulley when arın C, returns to the position shown in Figure 2.

page_text: On said disk N, are pivotally hung two other arms J, to the rear side of the
arms of pulley k, and on the extremities of said arms are pivoted two other.
shoes p, p, similar to said shoe j, but normally constantly acting through their
connection with the fixed disk N. by the said arms J, J, and the springs r, r, (the
latter connected to said arms and disk in a manner similar to that above described
relative to arm J, and spring 1,) to constitute friction brakes to prevent the rotation
of the pulley k, in a direction opposite to that indicated by the arrow 21, Figure 1.
The said arms J, J, constitute toggle connections between said disk N, and the
said shoes p, p.
In Figure 1, at the right of the upper end of lever R, is indicated the end of the
usual stop-motion shaft T, of a loom, and on said shaft is shown a curved lever T'.
Lever R, in practice, is supported in a position normally in contact, or nearly 80,
with the end of said curved lever T2, when the take-up devices are operating, but is
shown in Figure 1, slightly separated from said lever, to avoid confusion of parts.
A pin in the frame of the machine (see Figure 1) against which said lever R, is
shown to be resting, constitutes a stop for arresting the further movement of said
lever toward the shaft T.
When for any reason the usual stop-motion devices operate to stop the loom, the
arm T, swings against lever R, and swings it to the left, thereby carrying
pins t, 2, and t, against the arms J and J, thereby freeing all three of the said
shoes from frictional contact with the rim of pulley k, thereby stopping the
take-up action, and, consequently, slacking up the warp.
Said arm T' after acting against lever R, as described, is immediately retracted,
thereby letting the take-up mechanism and brakes, actuated by springs l, r, r,
return to their normal operative position, as shown in Figure 1. The hook on
lever R, extends over face of pulley k, and turns under to engage arm J, to
disengage shoej, from said pulley when said lever is swung to the left. This is
the first result of the swing of the lever R, by the stop-motion shaft or when
operated by hand, after which the lever disengages the friction shoes p, p, by striking
the arms J, J, thereby temporarily disconnecting the devices which intermittently
rotate pulley k, therefrom.
In order, when desired, to limit the backward movement given to pulley k, by
the tension of the warp when the brake-shoes are by the action of stop-motion
devices, suddenly disengaged from said pulley k, the devices illustrated in
Figures 7 and 8 are employed, and they consist of an arm 3, (on which are
other devices below described) pivotally attached to the front face of said fixed
disk N, by a screw 4, passing through a slot 5, therein, whereby said arm may be
free for more or less end wise movement, so that the grip of said other devices
carried thereby, upon the pulley k, may be facilitated. A stop-pin 6, is placed in
the face of said disk to limit the downward movement of arm 3. Said Figure 7
illustrated in perspective said arm 3, and its connected mechanism, in engagement
with the rim of the pulley k, there indicated in dotted lines.
Figure 8 shows a section of said pulley and illustrates the devices in a position
of disengagement from said pulley-rim.
Figure 7 further illustrates a stop-bar 13, adjustably secured on said disk N,
which provides means for limiting the rotary movement of the pulley k, in the
direction of the take-up (see arrows 21, Figures 1 and 2) so that said pulley, when
the lay-frame is moving very rapidly, (in weaving a great number of picks per
minute) shall not be unduly turned by its take-up actuating devices.
Said arm 3, has pivoted thereon, a latch 7, and on the free end of said latch a
brake-shoe 8, is pivotally connected to it by a shaft 9, which extends through said
latch and shoe, and over the upper edge of the arm 3, and beyond the farther side
thereof.
'
An arm 10, is fixed on the end of shaft 9, as shown, having a notch 22, therein,
for engagement with a pin o, o, on arm 3, when said latch 7, is moved up to the
position shown in Figure 8. The disengagement of the brake-shoc 8, from the
pulley-rim as shown in Figure 8, permits the pulley to be turned in a direction

page_text: opposite to the take-up motion. A spring 12, acts to press the brake-shoe 8, against
the pulley-rim.
The bar 11, on arm 3, constitutes an abutment between which and the shoe 8,
the said rim is clamped.
The operation of the above described parts shown in Figures 7 and 8, which
are connected to disk N, whereby the slacking up of the fabric and warp, when
the take-up mechanism is released. is controlled, and whereby the backward
movement of pulley k, caused by the tension of the warp, is limited, as above
set forth, and whereby the said over-throw of pulley k, is prevented, is as
follows:-
The normal position of the arm 3, and the devices carried thereby, is that shown
in Figure 7. Pulley k, is turned, in taking-up, in the direction of the arrow in said
last-named figure.
When the loom is in operation, the power exerted on shaft K, and in the take-up
devices, is in the direction of the arrow 21. If, by reason of the breaking of a
thread, the stop-motion devices on the loom are brought in action, there always
intervenes a short space of time between such break in the thread and the
operation of the stop-motion through its shaft T, and its arm T², to disengage the
arm having the friction shoe thereon, and thus by the release of pulley k, on shaft K,
relieve the strain on the fabric which is maintained by the said take-up devices.
At times enough movement in the fabric takes place during such interval to show,
when the loom is next started up, a space more or less wide which looks as if one
or more of the shuttle-threads had been left out, whereas it is caused only by
reason of the slight excessive take-up of the warp after the stop-motion devices
have been set in operation and before such devices have released the take-up
mechanism as described.
The devices shown principally in Figure 7 obviate this difficulty,, as
follows:-
As has been said, the power applied to shaft K, is, during the operation of
the loon, in direction of arrow, 21. Now, should the stop-motion devices be set
in operation by the breaking of the thread, as soon as the friction-shoes on
arms J, J', have been released the tension under which the cloth has been taken
up on the cloth-beam immediately operates through gear W, on the cloth-beam
and the pinion M, on shaft K, to reverse said shaft K, and slack up the cloth and
warp to such a degree as may have been determined upon by the adjustment of
the stop-arm 13, and the projection y, on arm 3, which when said reversed
movement of shaft K, in a direction opposite to arrow 21, takes place, come into
contact; and the engagement of the clutch device on arm 3, with the rim of the
pulley, arrests the said reversed movement of shaft K. The fabric and warp may
be slacked up to a greater or less degree as desired by the suitable adjustment of
the stop-arm 13, on the disk N, relative to said projection y, on arm 3.
If the pulley k, tends to throw too far around in rapid weaving, the adjustable
stop-bar 13, is set with its extremity so near the projection y, ou arm 3, that any
excess of movement of pulley k, will swing arm 3, against the end of said stop-
bar 13, and stop the movement of the pulley. The said stop-bar 13, is made, in
practice, of the form and proportions shown in Figure 7, and is secured adjustably
on disk N, by a single screw-bolt through its slot, but if found desirable the bar
and the screw-bolt may be made proportionately heavier.
By seizing the arm 10, on latch 7, and lifting it, and securing it in the position
shown in Figure 8, the devices on arm 3, are rendered inactive.
Figure 4 shows in perspective the upper end of the lever I, the boss 16.
thereon, and a section of the arm J, of Figure 1, and illustrates the preferred
manner of jointing said arm to said lever (all of the arms carrying the frictional
shoes are provided with this adjustment) which is as follows:-
A bushing O, is eccentrically pivoted on said boss, and the arm J, is hung on
said eccentric bushing. It is desirable that suitable means be provided for
carefully adjusting the arms J and J, endwise, in order to insure suitable

page_text: whereby said lever is given a vibratory movement, a disk fixed on the journal-box
of said shaft near said pulley, an arm 3, having an adjustable pivotal connection
with one face of said disk, and having the bar 11, thereon which engages with the
outer surface of the rim of said pulley, a latch pivoted on the side of said last
named arm, a brake-shoe pivoted on said latch opposite said bar, a spring carrying
said brake-shoe against the inner face of the rim of said pulley and a latch-lifting
arm pivoted near the end of said latch, whereby said brake-shoe is lifted out of
connection with said pulley, substantially as set forth.
