Improvements in and connected with Anti-ballooning Plates or
Yarn Separators for Spinning Frames.
I, ALFRED DAVIS CHANDLER, of Chelmsford, in the County of Middlesex and
Commonwealth of Massachusetts, one of the United States of America, Machinist,
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:-
My invention relates to yarn-separators for spinning-frames and consists in the
devices and combinations hereinafter described and claimed, the object of said
invention being to provide means of counter-balancing the weight of the separators
and of their supporting and actuating devices; means of varying the limit of
traverse of the separators; means of guiding the separator-rods; means of enabling
the separators to be turned up out of the way in doffing or for other purposes; and
means of holding the separators in a raised position and in other respects, herein-
after stated, to improve the construction of the parts which support and operate the
separating-devices.

tails "b; the ring-rail C; the lifting-rod c, guided in the spindle-rail D and guide-
rail E, the cross-shaft F, turning in brackets f, secured to said guide-rail and
provided with a cross-shaft-arin, the free end of which carries the horizontal

construction and operation.

Each cross-shaft F (one being shown) is provided with a so-called swivel-arm f
to the upper end of which is jointed the swivel f*, connected by a rod f' to the
next swivel, there being in practice as many cross-shafts F as there are lifting
rods c at one side of the spinning-frame. To the swivel-arm nearest the so-called.
builder-cam V is connected one end of a chain which runs over a chain-pulley or
grooved idle-roll v¹ and, at the other end is secured to the upper end of a curved
rack which is adjustably connected to the builder-arm 3, said arm having a
hub, turning on a stud v', projecting from the frame of the machine, and an anti-
friction roll being journalled in said arm below the builder-cam V, and being
held against said builder-cam by a weight f8, adjustably supported on the weight-
lever or weight-arm f' of the cross-shaft-arm f, the downward motion of both said
arms being caused by the pressure of said builder-cam V upon said roll v.
The rack is engaged by a worin ° (indicated by a dotted circle in Fig. 15)
fast on the worm-shaft ' journalled in the builder-arm 3, and the ratchet is also
fast on said worm-shaft and is engaged by a pawl, pivoted on the weighted
pawl-arm, and having an arm vll which is struck by a dagger o, secured on the
frame of the machine, when the builder-arm is raised gradually, to shorten the
traverse of the ring-rail by carrying the lower end of the chain nearer to
the centre of motion of the builder-arm.
The parts which operate the builder-arm and cross-shaft-arm are all of the usual s
construction and operation. It will be seen that the ring-rail is raised by the
falling of the weight f" and falls by its own gravity and the gravity of its connected
parts.
The separators are of sheet-metal and are secured by screws i to the separator-
bar J which is arranged back of the ring-rail, parallel therewith, and has secured
to it as many brackets K as there are separator-rods N. Each bracket Kis
provided with two laterally-projecting pins parallel with each other and with
the axis of the bar J. The pin k enters a slot in the top of the socket L and
serves as a pivot on which the bar J may be turned to raise the separators I out
from between the spindles or to restore said seperators to operative position, the
lower end of said slot being rounded to fit the pivot-pin k'. The socket L has in
front of the slot 1 a projection l', curved concentrically with the rounded lower end
of the slot l, the distance between the lower end of said slot and the curved surface
of said projection being equal to the space between the pins k. When the
separators are turned down into the position shown in Figs. 2 and 5, the pin ³
rests in a depression on the front of the socket-piece at the lower end of said
projection. The foregoing description applies equally to the Improvement in
Yarn-separators for Spinning-frames, described in Letters Patent to me, No. 10,972,
dated June 10, 1892, but the slot in this application is vertical on the front side,
except that it is cut under at the bottom, at 1, to fit the pin k¹, whereas in said.
Patent the corresponding slot has straight parallel backward-inclined front and
rear sides. The reason for making the principal part of the slot / vertical in this
application is to enable the separator-bar and the separators to be lifted vertically,
drawing the pivot-pins k¹ out of the sockets L, when it is desired to remove said
bar or separators for any purpose, without striking a roller-beam, in spinning-
frames where the roller-beam extends so far forward as to be struck by the
separators if said slots / were backwardly-inclined..
Each socket-piece is provided with an upwardly-projecting stop 1, substantially

page_text: as in said Patent, except that instead of the separator-bar J striking said stop when
the separators are turned up from between the spindles, the bracket K, shown and
described in this application, is provided with a lateral projection which, striking
against said stop prevents the further backward movement of the separators.
The separator-bar, when in its normal position, is prevented from being disengaged
from the socket-piece by the projection and pin holding the pivot-pin k¹ in the
lower portion of the slot 1, but when the separators are lifted the pins k¹ are in
the position shown in Fig. 6, and allow the pivot-pin k' to be moved back sufficiently
to rise in the slot (.
The projection is arranged between the separator-bar K and the pivot-pin k¹
and is below the top of said separator-bar, as shown in Fig. 5, and therefore allows
of the back of the stop being placed as far forward as the back of the socket L,
and therefore allows the socket to be arranged at a less horizontal distance from
the roller-beam than it was possible to place the corresponding stops and socket in
the device shown in said Patent.
As in said Patent, the socket-piece L has a collar held on the upper end of a
vertical separator-rod N by a set-screw turning in said collar and thrusting
against said rod, there being as many separator-rods as there are lifting-rods, said
separator-rods sliding in the sleeves in m¹ at a stand M secured to the guide-rail E
by bolts m (see Fig. 1) and being raised by the rising of a cross-shaft-arm ", the
stud supporting an anti-friction roll f', precisely like the roll f³ above referred
to but arranged on the opposite side of said arm f¹, each separator-rod being
provided with a foot O (see Figs. 1, 2 and 8), the lower end of which rests on the
anti-friction roll f* during the traverse of said separator-rod. Said stand M and
foot O differ, however, from the corresponding parts shown in said Patent, as will
hereinafter more fully appear.
The stand M between the sleeves m m¹ is provided with a vertical slot m³ to
receive a projection p¹ on an adjustable collar P which surrounds the separator-
rod N and is held at any desired distance above the foot of said separator-rod by a
set-screw Р which thrusts against said separator-rod, said collar P limiting the
downward movement of the separator by striking on the top of the lower sleeve m¹
on the stand M and its projection p' laterally filling the slot m³ and preventing the
separator-rod from twisting or turning on its axis when the separator-bar is lifted out
of the sockets, the collar P also serving as a stop-collar as above stated by striking
on the lower sleeve of the stand M instead of on the top of said stand, as described
in said Patent.
The foot m through which the bolts m² are driven to secure the stand M to the
guide-rail E may project horizontally forward below said_guide-rail while the
sleeves m m are engaged on the back of the stand (see Figs. 1, 2 and 7) or a
similar foot m³ and sleeves m m' may both project forward from the body of said
stand (see M', Fig. 12), the foot then being arranged on the top of the guide-rail,
the last-named construction bringing the separator-rods and separators farther
forward and into a position where they will not strike the lower edge of the roller-
beam in rising, in spinning-frames in which the horizontal distance between the
back of the ring-rail and the plane of the front face of the roller beam is very
short. The stand, when used near the support S of a spinning-frame of the usual
construction, is provided with a hanger m, preferably cast in one piece with said
stand, as shown in Figs. 7 and 12, and from said hanger near the lower end thereof
projects a fulcrum stud m² secured by any usual means to said hanger.
An anti-friction-roll Qturns on a stud q. which projects from a collar g',
djustably held by the set-screw 2 at the desired height on a separator-rod, and
on the fulcrum-stud m7 turns a lever T, one arm t of which is so curved that a
angent to said lever at the point of contact of said lever aud the anti-friction-
oll Q will be horizontal at all times, the other arm t¹ of said lever carrying a
liding weight R, which is held by means of a set-screw r, turning in said weight
gainst said arm t', at any desired distance from the fulcrum m', such distance being
o regulated as to allow the weight of the separator-rods and parts supported

page_text: thereby easily to raise the weighted arm of the lever T, when the free end of the
cross-shaft arm descends, the object of the lever T and its weight being, not to
raise the separators, but to take a part of the strain off from the cross-shaft, which
raises said separators precisely as the ring-rail is raised, that is, by means of the
weighted arm f and weight f³, this being the more necessary because the
separator-bar has a less traverse than the ring-rail and it is desirous to make
the traverse of the ring-rail as uniform and gradual as possible and to obviate
the necessity of increasing the size of the weight fa and the power required to
raise it.
The stud q is provided with an annular groove q³ near its free end, into which
groove a wire 9 is laid and bent around said stud, the wire being of sufficient size
to project from said groove and to form a collar on said stud and the end portions.
of the wire being pinched together, at 9, to retain the roll Qon said stud. In
the same way the lever T is retained on the stud m' by a wire m³ arranged partly
in the groove m' 10 near the free end of said last-named stud. (See Figs. 1, 9, 13
and 14.)
The construction above described allows the curved arm of the lever T
when placed below the guide-rail to swing without striking the support S of
the frame.
Except near the support S, the lever T may be pivoted between the ears m³ cast
on a stand M (Fig 11), in other respects like the stand M, shown in Fig. 7
(except that the hanger m shown in said last-named fig. is omitted as unneces-
sary), the curved arm t of said lever T in this case extending over the lower
sleeve m¹, from which said ears m³ project laterally and the anti-friction-roll Q
being supported by its collar ol between the guide-rail E and spindle-rail D and
the free end of the stud y sliding in the vertical slot just as the pin p¹ of the
collar P is described above as operating in respect to the stand M shown
in Fig. 7, said collar P, where the stand M', shown in Fig. 11, is used, being
arranged above the upper sleeve m of the stand and serving merely as a stop-
collar.
The adjustable foot O (instead of being formed in two parts, the upper of which
is secured on the lower end of the separator-rod and the lower of which is adjust-
able on said upper part, as in said Patent) consists of a single piece and has a
collar o to receive the lower end of the separator-rod N, a horizontal sole o' resting
upon the roll during the traverse of said separator-rod, as above described, and
connected to the collar by extensions o² from said collar. A set-screw o³ turns in
said collar o and thrusts against the separator-rod N, holding the sole of the foot o
on a level with or at any desired distance below the end of said rod N, to vary the
upper limit of the traverse of the separator-bar and separators.
The separator or separator-blade shown is different in form from what is shown
in said Patent and is designed to enable the separator to have a greater depth and
to secure a more perfect separation of the yarns and therefore to allow of a longer
traverse of the ring-rail and a greater speed of the spindles and the use of a
lighter traveller.
The shank of each separator I herein described, when in operative position, is
considerably higher than the middle of the separator instead of being at the same
height therewith, the separator not extending above the shank far enough to
prevent said separator, when near the upper end of its traverse, being thrown into
a vertical position against the roller-beam, but far enough to enable the upper end
of the separator to rise into the space between the nearest adjacent finger-
boards P and between the yarn-guides carried by said finger-boards.
Below the shank the separator reaches down for a distance depending on the
length of traverse, the speed of the spindles, the weight of the traveller, and the
number of the yarn, because the longer the traverse, the greater the speed of
the spindles, the lighter the traveller, or the heavier the yarn, the greater will be
"the balloon" described by the yarn and the greater will be the depth of the
separator required below the shank .

page_text: Separators which are drawn or swing backward from between adjacent spindles
as the ring-rail rises, must necessarily be of comparatively slight depth, to avoid
striking the roller-beam or being struck by the rising ring-rail and sometimes
consists of a plate not over one-eighth of an inch in thickness arranged horizon-
tally. I am enabled to use a blade three and a half inches or more in depth,
because my separator has a vertical traverse and moves upward out of the way of
the ring-rail. Using a separator of great depth, the traverse of the separator
may be much less than that of the ring-rail, because it is only necessary that the
separator should move upward far enough to avoid being struck by the ring-rail
and downward far enough to prevent the interference of the yarns of adjacent
spindles. I can therefore use a much longer traverse of the ring-rail, that is, use
much longer bobbins, run the spindles at a greater speed, use lighter travellers and
spin heavier yarn than would be possible with a separator of slight depth, it being
evident that with a long traverse, or under any of the circumstances above men-
tioned which increase the diameter of the balloon, a separator of slight depth
would allow the yarns of adjacent spindles to interfere above or below or both
above and below the separator.
The shape of the separators I as above described is such that the principal part
of their weight, when in a vertical position would obviously be in front of the
pivot-pin k and would cause them to fall forward. I therefore use a retainer U
of sheet-metal secured to the front of the roller-beam by a screw u which passes
through a slot u in the shank u², said retainer near its free end being rounded,
at u³, towards one of the separators on a separator-bar and adapted to press against
the sides thereof with considerable friction or to enter slightly one of the slots ?³
cut in each separator (to lessen the weight of the separators) and to hold all the
separators on said separator-bar in a vertical position.
In some spinning-frames, the horizontal distance from the vertical plane in which
the spindles stand to the front of. the roller-beam is sufficient to allow separators,
shaped as herein shown and described, to be tipped over backward until the centre
of gravity of the separators is in the rear of their pivot-pins and in such cases the
retainer U may be dispensed with.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
