Improvements in Cop and Bobbin Winding Machines.
We, OSWALD LEVER, of No. 2805 North Second Street, in the City of
Philadelphia, State of Pennsylvania, Engineer, and Machinist, and WILLIAM
SMITH GRUNDY, of No. 2809 North Second Street, also in said City of
Philadelphia, State of Pennsylvania, Engineer and Machinist, both in the
United States of America, 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 :--
Our invention relates to cop and bobbin winding mechanism, and consists, first,
in the combination with sets or groups of vertically arranged spindles and their
actuating gearing, of driving devices adapted to directly gear with and simul-
taneously actuate each, member of each set or group separately but with
uniformity and precision; second, in the supporting and actuating devices driving
and operating the vertical spindles; third, in the combination therewith, and with
the frame of the machine, of the stop mechanism operating on the breaking of a
thread to disengage the driving gear of the particular spindle carrying such
thread; and finally of the combination and arrangement with the yarn guides, their
actuating devices, the frame supporting the same, and the rotating spindles, of the
yarn-supplying devices and the mechanism for supporting and adjusting the
same.

brackets D', (see Figures 2 and 10) secured to the frame. These brackets
(see Figures 6 and 10) support the spindle driving bearings. The cogs D and
their brackets are so arranged in groups or sets in the frame on the opposite side-
rails A that their peripheries will all mesh with the cog gearing on the periphery
of the central cog C2, which in turn is driven as aforesaid by the main driving
shaft B. Secured to or made integral with the brackets D¹ are sleeves A³ which
support the tubular shafts A carrying the spindles A7.
The said side-rails A12 A12 each support a series of projecting spool supports A²
upon which are mounted the spools A³. They also support the said spindle
bearings hereinafter more particularly described and shown in detail in cross
section in Figure 6.
Mounted on each of the uprights A of the frame are supports A* carrying the
guide rod c¹. On each of said uprights A is also mounted a vertical arm A³ in
which a shaft K is journalled, the said shaft actuating the several yarn-guides C
in the series and which shaft is vibrated by the rod B³. At the upper part of
said. vertical arm A5 is also mounted the usual tension device c³. The rod B' (see
Figure 11) imparts a lateral reciprocating movement to the shaft X through a
bell-crank lever X' (see Figure 1) the said shaft. X carrying the lower yarn
guide c and its stop pin B5 which operates as hereinafter described.
The yarn guide with its stop pin B15 are journalled on the shaft X, and this
journal bearing while free to rotate on the said shaft is fixed against longitudinal
movement thereon, by means of collars, pins or other equivalent devices. The
shaft X has a lateral reciprocatory movement of a fractional part of an inch
produced by the rod B* actuating it through the bell crank lever X (see Fig. 1).
On the breaking of the yarn, the yarn guide c will fall (as shown by dotted lines
Fig. 10) thus carrying its stop pin B forward in line with the cam B. The
shaft X having a fateral reciprocatory movement, as before mentioned, will carry
the stop pin of the yarn guide mounted thereon, into contact with the cam and
upset it (as shown in Fig. 3) and thus release the spring controlled rod A and dis-
connect the gear D with the driving shaft of the spindle as before mentioned. The
parts are restored to their normal position by re-threading the yarn guide, and
raising the pivoted cam B5 by means of its handle D2 (see Figs. 5 and 11). The
arms A are projecting stationary posts on either side of the frame and 'support
the guide (see Fig. 1) which directs the course of the several strands of
yarn from the series of spools A³ to the wheels on the end of the several yarn
guides c'.
An extension A% of the upright A (shown in Fig. 12) is provided to support
the yarn reel E which is mounted on the end of an arm E¹ the other end of which
is pivoted at e in a double frame E² E³ which is slotted in an arc of a circle on
each side at E* E* terminating in a recess e¹. The yarn reel arm E¹ has an
operating handle E³ affixed to it, and a projecting pin e², the latter adapted to fit in
the slot E and recess e. This construction enables the yarn reel to be raised and
lowered in an arc of a circle by grasping the operating handle of its supporting
arm, and when raised the reel is adjustably locked in position by the pin e resting
in the recesse¹ of the slot E. The double frame E² E supports a similar yarn
reel and operating mechanism on each side.
The spindle A (see Figures 6 and 10) is square at its lower end and rests in a
square journal (see Figures 7, 8.and 9) in the tubular shaft A8 which rests in and
upon the sleeve A' which is secured to or made integral with the bracket D'.
The shaft A is recessed on its under end at to receive the pin A10 fixed on the
:face of the cog D. Said cog is mounted on the brackets D' (see Figure 2) and
actuates the spindles A mounted on the tubular shaft A8 and the said shaft A³
beneath the .cog has a collar F which has its bearing in a pronged arm F on the
base of the spring rod A carrying the stop mechanism hereinafter described. The
spring 9 encircles the rod A between the said prong F and an extension 6' of
the sleeve A and tends to withdraw the pins A10 of the cog D from the recesses b
in the shaft A when the rod A is no longer held up by the stop mechanism B³

page_text: hereinafter described.
Said stop mechanism 1S shown in normal position in
Figure 4.
The cop forming cup H is constructed integral with its supporting bracket H
and H2 and is secured through the bolt hole H³ to the supporting rail H* provided
therefor (see Figure 10). The rod A passes through a recess in the base H2 of
the cup supporting bracket and above and resting or the same are secured thereto
devices (shown in detail in Figures, 34 and 5 and in connection with the tension
devices in Figure 10) for throwing the spindle out of gear when a thread breaks.
These devices consist of a short cam B provided with a handle D, and pivoted in
a recess on the end of a bar screwed to the top end of the rod A. This cam is
shown in normal position in Figure 4, holding up the rod A®, and keeping the
driving cog D in register with the tubular shaft A. In Figure 3 it is shown
thrown down, whereby the rod AⓇ is released and the driving cog D thrown out of
register with the tubular shaft A. This is accomplished on the breaking of a
thread, by means of the stop pin B" which is mounted loosely on the shaft X and
in this stop pin is fastened by a set screw, the end of the yarn guide c, so that when
the thread breaks the yarn guide drops (as shown in Fig. 10) striking against and
upsetting the cam B' releasing the spring controlled rod A. A handle D² on the
cam enables it to be restored to normal position.
The operation of the device is as follows:-
Power being applied to the shaft B through the pulley. B', the horizontal cog C²
drives the several cogs D in the group or series with which it is geared, separately
but directly and with uniformity and at a minimum expenditure of power; and the
stoppage of the separate driving gear of any spindle in the group will not affect
the continued operation of the remaining spindles in the group.
Two or more of
such groups or sets, of preferably four spindles each, may be thus mounted and
driven from a single shaft; and the same shaft, by means of the eccentric B2 and
its rod B³ fixed upon one of its ends, will, with equal uniformity and precision,
operate the several yarn guides for each spindle in each of the several groups or
series of spindles through the shaft K and in unison with the mechanism actuating
the spindles.
Yarn is supplied from the small spools A³ (see Fig. 1) but preferably from and
by means of our improved yarn supplying devices shown in Figure 12. The
spindles are driven as described and form cops of yarn thereon, by means of the
cop-forming devices in the usual manner.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. The combination with one or more sets of vertically mounted cop and bobbin
forming spindles arranged in groups, vertical tubular shafts supported indirectly
from the frame and actuating said spindles, a horizontally rotating driving cog for
each of said tubular shafts, and a central horizontal driving cog, gearing with each
of said spindle driving gears, whereby all the spindles in a set or series are adapted
to directly gear with and be uniformly but separately driven by said central
horizontally rotating cog, substantially as described.
2. The combination with the supporting frame A A¹ A" the horizontal driving
shaft B, its gearing C¹, horizontal cog gearing C C2 driven thereby, a series of
