Improvements in Spinning or Twisting Machinery.
I, JAMES MARJERISON, of 7, Willoughby Street, Lawrence, in the County of
Essex and State of Massachusetts, one of the United States of America,
Machinist, do hereby declare the nature of this invention to be as follows:-
The invention to be herein described is intended as an improvement on the
class of machines described and shown in the Specification of Letters Patent
No. 6060, dated April 24, 1888 granted to me.
The specification referred to shows and describes a spinning frame employing
caps which are set on dead spindles, and the invention therein contained com-
prehends means for simultaneously removing the caps and the wound bobbins,
in order that the latter may be doffed, and thereafter the tubes on said spindles
have applied to them empty bobbins, and then the caps are returned upon the
tops of the spindles.
In this present invention, have been devised novel clamps or devices to handle
the caps; and also the full or wound bobbins and the empty bobbins.
1.
The clamps shown in said former specification consisted of levers connected
between their ends by a pivot, so that each carried a pair of pliers, but in practice
it was found that such clamps made as levers of the first order could not be
opened sufficiently wide to adapt the clamps to all diameters of caps and of wound
bobbins, and consequently said clamps have been improved.
'
My improved clamps, according to this invention present longer grasping
carried at the ends of two
portions, and said grasping portions are
stud located
on
a
at
a con-
levers mounted at their opposite ends
siderable distance from the line of the spindles, and said levers work
in a guide which controls and steadies them in their movement said
guide co-operating with said levers near their grasping portions, a spiral spring
connected at its opposite ends with both of said levers normally acting to keep
the grasping portions pressed one toward the other, but in a yielding manner,
so that each concaved grasping portion may move independently of the other as
it meets a cap, bobbin, or whatever is to be clamped."
The former patented machinery referred to was without means for holding the.
yarn between a full bobbin and the usual front rolls when the said bobbins were
to be doffed and empty bobbins were to be applied to the spindles, so that a second
set of bobbins could be quickly started.
Herein, however, I have provided for the first time, as I believe, automatic
means whereby, when the clamps have grasped a wound bobbin and removed it.
from its tube on the spindle, the yarn will be caught between the front rolls and
the wound bobbins, and will be put in such position that it may be clamped and
held by the empty bobbins as they are put upon the tubes and spindles, said
clamped yarn being readily wound on the bobbins just applied to the tubes and
spindles when the machine is again started, the tubes being rotated on the spindles
by usual banding common to said patent.
.1

page_text: The means provided for catching the yarn and putting it in position to be
clamped will be hereinafter more fully described.
In the former specification referred to the clamps for engaging the caps to
remove them from the spindles were carried by arms pivotally mounted on the
ends of clamp actuating levers, said arms normally occupying a position turned
back, down and away from the spindles, and they had to be turned up into opera-
tive position, to enable the clamps to engage the caps and remove them from the
spindles preparatory to other clamps engaging the wound bobbins and removing
them from the tubes and spindles.
These cap-holding clamps, having engaged the caps and having lifted them
from the spindles, were again turned back, down and away from the tubes and
spindles, they continuing to hold the caps while the wound bobbins were removed
by other clamps and empty bobbins were put back upon the tubes and spindles
by yet other clamps, after which the arms having the clamps engaging the caps
were again put back into elevated position as described, to enable the clamps
holding the caps to apply them to the tubes and spindles, preparatory to spinning
and winding the yarn on the bobbins just applied, and thereafter the levers carry-
ing said clamps were again turned back, down, and away from the spindles.
This operation was carried on by hand and required much time, and further,
the tipping over backwardly and downwardly of these clamp-carrying arms into
the usual alleyway between the frames seriously obstructed the alleyway which
was very objectionable because the alleyway space in all mills is limited and
should be always kept open and clear.
To obviate this trouble I mount the cap clamps on bars carried at the upper
ends of segmental toothed racks, said racks being fitted in guideways on levers
to be described, and to put said bar carrying said clamps, it normally occupying
its inoperative position, into its operative position, I provide a shaft having gears
to engage the teeth of said toothed racks, said shaft having attached to it at one
end of the frame a hand wheel by which it may be operated,
By this plan the alley-way is not at all obstructed.
I have also provided novel means for supporting the clamps holding the empty
bobbins.
The clamps which hold the empty bobbins to put them on to the usual tubes
carried by the spindles are peculiarly constructed, i.e., they have each a projec-
tion or finger which as the clamps are being turned off laterally from the bobbins
just put upon the tubes, acts to partially rotate each bobbin, the extent of each
rotation being just enough to enable the usual slots at the lower ends of the
bobbins, to engage and slip down on the usual bobbin driving studs or lugs carried
by the tubes, so that said bobbins are always properly seated on their driving
tubes, and in coming to their seats, the heads of the bobbins clamp the threads
then placed in position for said purpose by means of a thread catcher, and hold
the yarn firmly with relation to said tubes as the latter are started to wind the
yarn on a new set of bobbins.
The yarn on the new bobbins is broken off automatically, after a few turns of
the bobbin and tubes, and thereafter the full bobbins are by hand taken out of
the clamps holding them.
The thread catcher is preferably composed of a rocking and sliding shaft
having a series of hooked arms which are adapted to engage the yarns between
the usual guide-board and the wound bobbins, and by a lateral movement of the
thread catcher, they bear the yarns held by them laterally against the tubes, so
that when the empty bobbins come into position on the tubes, the said yarns are
each clamped by the bobbin.
Herein I employ for moving the various clamps, cam plates and levers which
differ but slightly from the cams and levers employed in the former specification
referrel to, the cams herein employed will preferably have longer slots and slightly
differently shaped chiefly to provide for longer bobbins.
The machine frame, the bottom rail extended from one to the other end of the

page_text: frame, the spindle rail carrying the dead spindles, the builder rail supporting the
band receiving portions of the tube, having suitable lugs to enter the usual
grooves in the lower ends of the bobbins; the cam plate for actuating the clamps
for carrying the empty bobbins, the lever having a pin entering the slot of said
cam plate and fixed to the rock. shaft; the cam plate having: cam grooves and
receiving the pin of a lever loose on said rock shaft, said lever and cam being
employed to actuate the clamps for. taking off the full bobbins, are and may be
all substantially as shown in said former Specification No. 6060 of 1888 with the
exception that the grooves in the cam plates here referred to are somewhat
differently shaped and made somewhat longer to thereby adapt the machine to
longer bobbins.
These present cam plates and other cam plates are suitably erected on the
bottom rail.
The builder or copping rail will in practice be raised and lowered to suitably
wind the yarn in bobbin form by mechanism substantially such as shown in said
former specification, or it may be by any usual builder mechanism commonly
employed in spinning frames.
The bottom roll, and the leather covered top roll, between which the yarn
passes on its way, toward and through the usual eye in the guide-board to the
bobbin, to be wound thereon, are and may be all such as are common in spinning
machinės..
i
Referring now to the devices for handling the empty bobbins, the rock shaft
has fast on it a hub having a projecting arm which receives a pivot on which is
mounted à lever having at its lower end an elongated slot which receives a bolt
so that by loosening said bolt and turning said lever on said pivot, its upper end
will be placed near to or farther from the spindle, as may be desired.
The lever has a stud upon which is mounted the lower end of an arm slotted;
said slot being entered by a guiding stud, so that said arm can turn on said pivot
and move longitudinally, or in the direction of the length of the spinning frame;
a bar having attached to it a series of empty bobbin clamps composed of two
pivotted members.
Each of these members has a concaved portion to embrace properly the barrel
of the empty bobbin and the one part has a projecting lug or finger, and the free
end of this part is kept pressed toward the bobbin grasped by it by a suitable
spring.
:
A portion of the empty bobbin clamp has a horizontally extended lug against
which the lower end or head of the empty bobbin stands when the said bobbins are
applied in said bobbin clamp, said lug enabling the heads of all the bobbins to
be placed at the same level, and also prevent any liability of the bobbins from
being dropped out of the position in said clamps, so that they might strike the
spindle when the arms and levers carrying said bobbin clamps were being put
into position to apply empty bobbins to the spindles.
:
The empty bobbin clamp carrying bar has attached to its underside a slotted
curved plate, said plate receiving a roller or other stud suitably connected with a
bar carrying the full bobbin clamps.
The full bobbin carrying bar has connected to its end a metallic yoke-shaped
piece having a rounded pin embraced loosely by the slotted upper end of a lever
mounted on a pivot carried by a bracket, carried by a rack, said lever being pro-
vided at its lower end with a slot in which is adjustably confined a roller or other
stud adapted to work in an irregular cam groove made in a cam plate having
suitable switches to control the movement of said stud and at the proper time to
vibrate the lever (referred to as having a slotted upper end) so that when the
rock shaft rises, as provided for in said former specification, the roller stud will
travel vertically in said slot, and when it descends, it will strike a switch and
move into the inclined or irregular part of said slot, passing finally into a part
of the slot under the switch.
1.
During this movement of the said lever about its pivot the said full bobbin bar

page_text: is slid longitudinally, carrying with it through the roller the (empty bobbin)
bar on which are mounted the empty bobbin carrying clamps.
The movement of this bar, while the roller is passing from the upper switch
beyond the lower switch is first to the right and then back to the left again.
Whilst the stud is standing in the truly vertical part of the slot in the cam
plate, the empty bobbin clamps stand with their bobbins at the left hand side
of the spindles containing the full or wound bobbins.
As the rock shaft rises, however, taking with it the bar carrying the empty
bobbin clamps, to put the heads of the bobbins about the tops of the spindles, the
roller passes the top switch and as the rock shaft starts to descend, said roller
meets said switch again, and the lever is turned, causing the connected (full and
empty bobbin) clamp bars to be moved quickly to the right, thus putting the
empty bobbin clamps with their empty bobbins directly opposite the spindles con-
taining the full bobbins, it being assumed, as will be described hereinafter, that
the full bobbin clamps engaged the full bobbins and removed them from the
spindles while the stud was rising in the vertical part of the slot, and while the
empty bobbin clamps are opposite the spindle, the curved lever will be moved by
the shape of the cam slot in its cam plate and the clamps and bobbins will be
carried toward the spindles, and said empty bobbins will be put over the tops of
the spindles and onto the tubes carried thereby, by the descent of the rock shaft,
the roller then travelling in the straight part joining the two inclines of the first
mentioned cam pláte and during such movement the rock shaft is also turned
by the later mentioned cam plate in a direction to move the said empty bobbin
clamps away from the spindles, the resulting two movements causing a finger con-
nected with a portion of the empty bobbin clamp, to be drawn off from the empty
bobbin in a diagonal path, so that the said finger operates against the side of the
empty bobbin and rotates it about the tube until the slotted lower end of the bobbin
correctly engages the driving lugs of the band receiving portion of the tube, so
that said bobbin may be immediately thereafter taken up and rotated in unison
with the said tube.
To confine the yarn correctly with relation to the empty bobbin and tube, so
that the yarn may be wound properly on the empty bobbin I mount in the
machine a rod (one end of which is exposed at one end of the machine and is pro-
vided with a suitable hand wheel) carrying a series of thread catchers.
When the operator is ready to doff a lot of full bobbins, the frame then standing
still, he will engage the rod or rock shaft, and will move it toward the left hand
end of the machine into a position at the opposite side of the full bobbin, so that
a little notch in the end of said thread catcher will engage the thread between
the usual thread eyes of the guide board and the fully wound bobbin, and will
carry it to the opposite side of the bobbin, and then the rock shaft will be turned
to move the thread catcher so as to swing it partially round and the full bobbin
is then taken hold of by the full bobbin clamps and the clamps are actuated 'to
remove the bobbins from the spindles.
While the full bobbins are being taken off the spindles, or just after they are
off, the operator pulls the rock shaft rod again to the right, thus leaving or
putting said thread between the catcher and the full bobbin, against the tube above
the lugs, and in this condition, when the empty bobbin is put upon the tube, and
is seated, as has been hereinbefore described, on the lugs, by the partial rotation
of said bobbin on said tube the thread is clamped firmly between the lower end
of the empty bobbins and the part of the tubes carrying the lugs, so that when
the tubes are again started in rotation, the yarn held as stated will travel with the
tubes and will be applied to the bobbins, the first two or three rotations of
the tubes breaking off the yarn between them and the full bobbins then held in
the full bobbin clamps, and thereafter the full bobbins may be removed by hand
in any usual manner from the clamps holding them.
After the tubes have been started in rotation to wind the yarn upon the empty

page_text: bobbins just applied to them, the operator by hand turns the rock-shaft rod to
again put the thread catchers in their inoperative position.
Caps substantially like those represented in said former Specification No. 60GO
of 1888, are adapted to be engaged by cap holding clamps composed of two like
jaws at the ends of lever arms pivoted on a stud each of said jaws presenting, a
concaved portion with an outflaring lip.
Said stud rises from an arm secured to the bar or rail said arm having attached
to and rising from it a guide or support in which the said lever arms are free to
move, said guides supporting said arms near their concaved portions.
Each of these lever arms has a suitable stud over which is caught the opposite
end of a spring, said spring controlling both parts of said clamp and enabling
either arm to move if required in excess of the other arm, to properly fit the cap.
The bar or rail just referred to has attached to it at suitable intervals segmental
rack bars which fit suitable guideways carried by the upper ends of levers mounted
to turn loosely on the rock shaft, each of said levers having at its lower end, a
projecting arm having a slot in which is placed a roller or other stud which enters
and slides in a groove in a cam groove plate, said plate having a switch controlled
by a spring.
The levers just mentioned have suitable bearings to receive a shaft provided
with pinions one for each segmental rack.
Said shaft has mounted on it loosely the hub of an arm having a pin entering
a hole in the part of a guide plate attached to the upper end of the one of the said
levers and said shaft, at the right hand side of the hub of said arm, has fixed on
it a collar.
A spring surrounding said shaft acts normally to draw it toward the left keep-
ing the pin in the hole in the said guide.
During the time that the spinning frame is spinning yarn and winding the
same, the segmental bars stand in their lowered positions, leaving the clamps
down in position nearly opposite the bobbins being wound, and when it is desired
that the clamps shall engage and remove the caps, or it may be
a flyer instead of a
then
cap,
а
the operator engages suitable hand
wheel on said shaft turns it causing gears in engagement with the
teeth of the segmental rack bars mentioned to elevate the cap clamps and then the
rock shaft is raised, whereupon the roller stud referred to rises in the said slot
and meets the switch which acts to quickly turn the clamps toward the caps,
forcing the clamps onto and so as to embrace the caps firmly, said caps engaged
by the said clamps being removed from the upper ends of the spindles as the
rock shaft continues its rising movement.
The cap holding clamps hold the caps firmly, and when the rock shaft is again
lowered at the proper time, the full bobbin in the meantime having been removed
and an empty bobbin having been applied to the tubes on the spindles, the said
caps are put upon the tops of the spindles, and after the rock shaft has arrived in
its lowermost position and the said levers mounted thereon have been moved to
the left to pull the clamps laterally from the caps, the operator engages an arm,
moves it to the right, thus removing a pin carried by said arm from underneath
the rack bar where it stood to hold up said rack bar during the operation of
doffing, the removal of said pin from underneath said rack bar permitting the
rack bar to descend again into its normal position.
During the descent of this rack bar its teeth remain in mesh with the teeth of
the said gear, the teeth of which being long enough to remain in mesh with said
rack bar, notwithstanding the longitudinal movement of the gear with the shaft,
the spring permitting this movement of the shaft.
arm
Clamps for engaging the full bobbin and removing the same from the tube on
the spindle are each composed of two concaved jaws carried each by an
mounted to turn on a stud screw in the underside of an arm attached by a suitable
screw to a bar. said arms having each a suitable stud or groove with which are

page_text: connected the opposite ends of a spring normally acting to keep said jaws closed,
but permitting them to yield as the acting free end of sáid jaws meet the surface
of the wound bobbin as the said jaws are being moved toward the said bobbin to
grasp it frictionally.
+
The said bar carrying these clamps is mounted on the upper end of a suitable
pivoted arm on a pivoted lever on an arm of a hub loose on the rock, shaft the
lower end of said lever having a slot which is entered by a bolt said bolt serving
to secure said lever in any desired adjustable relation to the lever mounted loosely
on the rock shaft and having a roller or other stud entering the cam slot in the
cam plate.
The just mentioned pivoted lever is adjusted, when desired, to normally keep
the front edges of the jaws or clamps substantially close to the surface of the
wound mass of thread on the bobbins, so that when said clamps are moved to
embrace and grasp the wound bobbins, the extent of movement may be reduced
to the minimum.
Assuming that the rock shaft is in its lowest position and the stud is in the
bottom of the slot in the first mentioned cam plate; then in this condition the
clamp will stand a little below the spindle rail and as the rock shaft is raised;
the said pin soon arrives opposite the said little projection and as said pin travels
through part of the slot the clamps will be moved towards the right, to engage
the full bobbins, and as the rock shaft continues to rise the said pin will rise
through part of said slot, the clamps at such time, in engagement with the full
bobbins, acting to lift them vertically off from the tubes and spindles, the caps
having been previously removed, and finally, when the full bobbins have been
fully removed, the pin passes the free end of the switch and immediately there-
after the weight of the full bobbins removed from the tubes and spindles is
sufficient to cause the levers to turn on the rock shaft until the pin meets the
straight side of said cam plate.
Now it has been described that the empty bobbin carrying clamp moves to the
right to bring its bobbins into position opposite the spindles from which the full
bobbins have just been taken, and during this movement the bar carrying the
full bobbin clamps, they containing full bobbins, is also moved with it to the
right, the jointing of the pivoted arm to the pivoted lever permitting of this move-
ment.
The main shaft is supported in suitable bearings from the bottom rail.
This shaft may be driven by power in any usual manner to operate the machine,
so that it will rotate a certain number of times in one direction, and then it may
be reversed to rotate a certain number of times in the opposite direction.
This shaft has a pinion and when said shaft is rotated to move the pinion in
one direction the rack carrying the rock shaft is raised in order that the different
levers and devices carried by it may be raised in the act of removing the caps and
taking off the full bobbins, and when the shaft is lowered, the empty bobbins may
be put on and thereafter the caps put in position on the tops of the spindles.
To do this the main shaft has substantially two rotations in one direction and
then two rotations in the opposite direction.
This shaft in practice is put under such control that it may be stopped at any
position, no matter what its direction of rotation.
:
The dead spindles are confined to the builder rail in novel manner.
Usually each spindle has been held in place by a set screw inserted in the rail,
its end acting against the spindle.
According to the invention herein described each spindle has its lowest end
provided with a screw thread which is screwed into a threaded part of a split or
clamping nut provided with a clamping set screw which may be set up to hold
the lower end of the spindle in adjusted position.
The split nut has adjustably attached to it by a set screw a lipped finger.
The spindle may have its foot set in a threaded hole and the spindle may then
be put up through the hole in the builder rail until the nut meets the underside of

page_text: the said rail and the lipped. finger will then be confined in position with its lip
on the upper side of the rail, and the spindle when adjusted to put its top at the
proper level will be held firmly by turning in the set screw..

Improvements in Spinning or Twisting Machinery.
I, JAMES MARJERISON, of 7, Willoughby Street, Lawrence, in the County of
Essex, and State 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:-
The invention to be herein described is intended as an improvement on the
class of machines described and shown in the Specification of Letters Patent
No. 6060, dated April 24, 1888 granted to me.
The specification referred to shows and describes a spinning frame employing
caps which are set on dead spindles, and the invention therein contained com-
prehends means for simultaneously removing the caps and the wound bobbins,
in order that the latter may be doffed, and thereafter the tubes on said spindles
have applied to them empty bobbins, and then the caps are returned upon the
tops of the spindles.
In this present invention I have devised novel clamps or devices to handle
the caps; and also the full or wound bobbins and the empty bobbins.
The clamps shown in said former specification consisted of levers connected
between their ends by a pivot, so that each carried a pair of pliers, but in practice
it was found that such clamps made as levers of the first order could not be
opened sufficiently wide to adapt the clamps, to all diameters of caps and of wound
bobbins, and consequently said clamps have been improved.
My improved clamps, according to this invention,, present longer grasping
portions, and said grasping portions are
carried at the ends of two
levers mounted at their opposite ends on a stud located at a con-
siderable distance from the line of the spindles, and said levers work
in a guide which controls and steadies them in their movement, said
guide co-operating with said levers near their grasping, portions, a spiral spring
connected at its opposite ends with both of said levers normally acting to keep
the grasping portions pressed one toward the other, but in a yielding manner,
50. that each concaved grasping portion may move independently of the other as
it meets a cap, bobbin, or whatever is to be clamped.
The former patented machinery referred to was without means for holding the
yarn between a full bobbin and the usual front rolls when the said bobbins were
to be doffed and empty bobbins were to be applied to the spindles, so that a second
set of bobbins could be quickly started..
Herein, however, I have provided for the first time, as I believe, automatic
means whereby, when the clamps have grasped a wound bobbin and removed it
from its tube on the spindle, the yarn will be caught between the front rolls and
the wound bobbins, and will be put in such position that it may be clamped and
held by the empty bobbins as they are put upon the tubes and spindles, said
clamped yarn being readily wound on the bobbins just applied to the tubes and
▾

page_text: spindles when the machine is again started, the tubes being rotated on the spindles
by usual banding common to said patent.
The means provided for catching the yarn and putting it in position to be
clamped will be hereinafter more fully described.
In the former specification referred to the clamps for engaging the caps to
remove them from the spindles were carried by arms pivotally mounted on the
ends of clamp actuating levers, said arms normally occupying a position turned
back, down and away from the spindles, and they had to be turned up into opera-
tive position, to enable the clamps to engage the caps and remove them from the
spindles preparatory to other clamps engaging the wound bobbins and removing
them from the tubes and spindles.
These cap-holding clamps, having engaged the caps and having lifted them
from the spindles, were again turned back, down, and away from the tubes and
spindles, they continuing to hold the caps while the wound bobbins were removed
by other clamps and empty bobbins were put back upon the tubes and spindles
by yet other clamps, after which the arms having the clamps engaging the caps
were again put back into elevated position as described, to enable the clamps
holding the caps to apply them to the tubes and spindles, preparatory to spinning
and winding the yarn on the bobbins just applied, and thereafter the levers carry-
ing said clamps were again turned back, down, and away from the spindles.
This operation was carried on by hand and required much time, and further,
the tipping over backwardly and downwardly of these clamp-carrying arms into
the usual alleyway between the frames seriously obstructed the alleyway which
was very objectionable because the alleyway space in all mills is limited and
should be always kept open and clear.
To obviate this trouble I mounted the cap clamps on bars carried at the upper
ends of segmental toothed racks, said racks being fitted in guideways on levers
to be described, and to put said bar carrying said clamps, it normally occupying
its inoperative position, into its operative position, I provide a shaft having gears
to engage the teeth of said toothed racks, said shaft having attached to it at one
end of the frame a hand wheel by which it may be operated.
By this plan the alleyway is not at all obstructed.
I have also provided novel means for supporting the clamps holding the empty
bobbins.
The clamps which hold the empty bobbins to put them on to the usual tubes
carried by the spindles are peculiarly constructed, -.e., they have each a projec-
tion or finger which as the clamps are being turned off laterally from the bobbins
just put upon the tubes, acts to partially rotate each bobbin, the extent of each
rotation being just enough to enable the usual slots at the lower ends of the
bobbins, to engage and slip down on the usual bobbin driving studs or lugs carried
by the tubes, so that said bobbins are always properly seated on their driving
tubes, and in coming to their seats, the heads of the bobbins clamp the threads
then placed in position for said purpose by means of a thread catcher, and hold
the yarn firmly with relation to said tubes as the latter are started to wind the
yarn on a new set of bobbins.
The yarn on the new bobbins is broken off automatically, after a few turns of
the bobbin and tubes, and thereafter the full bobbins are by hand taken out of
the clamps holding them.
The thread catcher is herein shown as composed of a rocking and sliding shaft
having a series of hooked arms which are adapted to engage the yarns between
the usual guide board and the wound bobbins, and by a lateral movement of the
thread catcher, they bear the yarns held by them laterally against the tubes, so
that when the empty bobbins come into position on the tubes, the said yarns are
each clamped by the bobbin.
Herein I employ for moving the various clamps, cam plates and levers which
differ but slightly from the cams and levers employed in the former specification

page_text: referred to, the cams herein shown having longer slots and being slightly
differently shaped chiefly to provide for longer bobbins.

The machine frame A, the bottom rail A¹ extended from one to the other end
of the frame, the spindle rail A2 carrying the dead spindles 133, the builder rail d²
supporting the band receiving portions of the tube 24, having suitable lugs 26,
to enter the usual grooves in the lower ends of the bobbins ; the cam plate f³
for actuating the clamps for carrying the empty bobbins, the lever f having a
pin fentering the slot of said cam plate and fixed to the rock shaft e; the cam
plate h¹ having cam grooves and receiving the pin 15 of a lever h loose on said
rock shaft e, said lever and cam being employed to actuate the clamps for taking
off the full bobbins, are and may be all substantially as shown in said former
Specification No. 6060 of 1888 with the exception that the grooves in the cam
plates here referred to are somewhat differently shaped and made somewhat longer
to thereby adapt the machine to longer bobbins.
These cam plates and other cam plates to be described are suitably erected on
the bottom rail.
The builder or copping rail will in practice be raised and lowered to suitably
wind the yarn in bobbin form by mechanism substantially such as shown in said
former specification, or it may be by any usual builder mechanism commonly
employed in spinning frámes.
The bottom roll A, and the leather covered top roll A5, between which the
yarn passes on its way toward and through the usual eye in the guide board A6
to the bobbin, to be wound thereon, are and may be all as common in spinning
machines.
In Figs. 2, 7, 8, and this guide board is shown by full lines as turned up in
its inoperative position for doffing, but it is shown by dotted and full-lines in
Figs. 2 and 3 as turned down into its operative position.
Referring now to the devices for handling the empty bobbins, the rock shaft e
has fast on it a hub having a projecting arm h³ which receives a pivot h6 on which
is mounted a lever h having at its lower end an elongated slot which receives a
holt 8, so that by loosening said bolt and turning said lever hon said pivot 16,
its upper end will be placed near to or farther from the spindle, as may be desired.
The lever has a stud 8* upon which is mounted the lower end of an arm h
slotted as at 10, said slot being entered by a guiding stud 12, so that said arm
5 can turn on said pivot and move longitudinally or in the direction of the length
of the spinning frame, a bar 13 having attached to it a series of empty bobbin
B

page_text: clamps composed of two members 14 and 15, the member h¹5 being pivotted to
the member h14 at 16:
Each of these members has a concaved portion to embrace properly the barrel
of the empty bobbin d, and the part has a projecting lug or finger h, see
Fig. 4, and the free end of said part 5 is kept pressed toward the bobbin grasped
by it by a suitable spring h¹8.
The portion 14 of the empty bobbin clamp has a horizontally extended lug 20
against which the lower end or head of the bobbin d stands when the said bobbins
are applied in said bobbin clamp, said lug enabling the heads of all the bobbins
to be placed at the same level, and also prevent any liability of the bobbins from
being dropped down out of the position in said clamps, so that they might. strike
the spindle when the arms and levers carrying said bobbin clamps were being put
into position to apply empty bobbins to the spindles.
The bar 3 has attached to its under side a slotted curved plate ha, said plate
receiving a roller or other stud 2 suitably connected with a bar 123 carrying, the
full bobbin clamps to be described.
The bar has connected to its end a metallic yoke shaped piece h2*, see
Fig. 9, said yoke having a rounded pin which is embraced loosely by the
slotted upper end of a lever has, (Fig. 1) mounted on a pivot h25 carried by a
bracket 50 carried by the rack D³, said lever being provided at its lower end with
a slot in which is adjustably confined a roller or other stud 26, said stud being
adapted to work in the irregular cam groove 27 made in a cam plate 28, said
plate having suitable switches 29 and 30 to control the movement of said
stud 26, and at the proper time to vibrate the lever 24, so that when the rock
shaft rises, as provided for in said former specification, the roller stud will
travel vertically in said slot, and when it descends, it will strike the switch h
and move into the inclined or irregular part 40 of said slot, passing finally into
the part 41 of the slot and thence under the switch 29, into the lower straight
part of said slot.
During this movement of the lever 24 about its pivot
slid longitudinally, carrying with it through the roller
is mounted the empty bobbin carrying clamps.
the said bar his
the bar h¹³ on which
It will be noticed that the movement of this bar, while the roller 2 is passing
from the switch beyond the switch 29, is first to the right viewing Fig. 1, and
then back to the left again.
Fig. 1 shows the stud 26 standing in the truly vertical part of the slot in the
cam plate 28, the empty bobbin clamps at such time standing with their bobbins
at the left hand side of the spindles B³ containing the full or wound bobbins.
As the rock shaft 6 rises, however, taking with it the bar 3 carrying said
clamps, to put the heads of the bobbins about the tops of the spindles, the
roller passes the switch 30, and as the rock shaft e starts to descend, said
roller meets said switch again, and the bar 2 is turned, causing the connected
bars 23 and 13 to be moved quickly to the right, thus putting the empty bobbin
clamps with their empty bobbins directly opposite the spindles containing the
full bobbins, it being assumed, as will be described hereinafter, that the full
bobbin clamps engaged the full bobbins and removed them from the spindles
while the stud h26 was rising in the vertical part of the slot, and while the empty
bobbin clamps are opposite the spindle, the lever f will be moved by the shape
of the cam slot in the cam plate f³, and the clamps and bobbin's will be carried
toward the spindles, and said empty bobbins will be put over the tops of the
spindles and onto the tubes carried thereby, by the descent of the rock shaft (,
the roller 28 then travelling in the part 40 of the cam plate h2, and during such
movement the rock shaft e is also turned by the cam plate f³ in a direction to
move the said empty bobbin clamps away from the spindles, the resulting two
movements causing the finger h", connected with the portion 5 of the empty
bobbin clamp, to be drawn off from the empty bobbin in a diagonal path, so

page_text: that the said finger h operates against the side of the empty bobbin and rotates
it about the tube until the slotted lower end of the bobbin correctly engages the
driving lugs 26 of the band receiving portion of the tube 24, so that said bobbin
may be immediately thereafter taken up and rotated in unison with the said tube.
At this point I will describe the manner of confining the yarn correctly with
relation to the empty bobbin and tube, so that the yarn may be wound properly
on the empty_bobbin.
To do this I mount in the machine a rod a20, one end of which is exposed at
one end of the machine where it is provided with a suitable hand wheel, not
shown, by which to turn it.
This rod has fixed on it in suitable manner a series of thread catchers aª¹.
These thread catchers normally occupy when the frame is running regularly,
the position shown by dotted lines in Fig. 2, and full lines Fig. 3, a thread catcher
lying near one side of each of the separators 22, as represented in the full line
position Fig. 3.
When the operator is ready to doff a lot of full bobbins, the frame then standing
still, he will engage the rod or rock shaft a20, and will move it toward the left
hand end of the machine, from the position Fig. 3, into the position at the
opposite side of the full bobbin, so that a little notch a2+ in the end of said thread
catcher will engage the thread between the usual thread dyes of the guide
board A and the fully wound bobbin, and will carry it to the opposite side of the
bobbin, and then the rock shaft a will be turned to move the thread catcher
from its dotted line position Fig. 2 into the dotted line position Fig. 3, and the
full bobbin is then taken hold of by the full bobbin clamps and the clamps are
actuated to remove the bobbins from the spindles.
While the full bobbins are being taken off the spindles, or just after they are off, the
operator pulls the rod a again to the right, from the dotted line position Fig. 3
into the full line position in Figs. 1, 2 and 4, thus leaving or putting said thread
between the catcher and the full bobbin, against the tube above the lugs 26, and
in this condition, when the empty bobbin is put upon the tube 24 and is seated,
as has been herein before described, on the lugs, by the partial rotation of said
bobbin on said tube the thread is clamped firmly between the lower end of the
empty bobbins and the part of the tubes carrying the lugs, so that when the
tubes are again started in rotation, the yarn held as stated will travel with the
tubes and will be applied to the bobbins, the first two or three rotations of the tubes
breaking off the yarn between them and the full bobbins then held in the
full bobbin clamps, and thereafter the full bobbins may be removed by hand in
any usual manner from the clamps holding them.
After the tubes have been started in rotation to wind the yarn upon the empty
bobbins just applied to them, the operator by hand turns the rod a to again put
the thread catchers in their inoperative position, as represented by dotted lines
in Fig. 2 and full lines in Fig. 3.
The caps 33, substantially like those represented in said former Specification
No. 6060 of 1888, are adapted to be engaged by the cap holding clamps 620 com-
posed of two like jaws at the ends of levers 62 pivotted at their outer ends each
on a stud 623, each of said jaws presenting, see Fig. 5, a concaved portion with
an outflaring lip 621.
The studs 623 rise from arms 624 secured to a bar or rail w, each of said arms.
presenting at its inner end a rigid guiding loop 625 in which the levers 622
are freely movable, said loops guiding and supporting said levers between the
studs 623 and their concaved acting portions or ends.
Each of these levers has a suitable stud over which is caught the opposite
end of a spring 626, said spring controlling both parts of said clamp and enabling
either lever to move, if required, in excess of the other lever to thereby enable
the jaws to properly adapt themselves to the cap.
The bar has attached to it at suitable intervals segmental rack bars 687 which

page_text: .
fit suitable guideways 628 carried by the upper ends of levers 629 mounted to turn
loosely on the rock shaft es, each of said levers having at its lower end, as herein
shown, a projecting arm 630 having a slot in which is placed the roller or other
stud which enters and slides in a groove 63 in the cam groove plate w, said
plate having a switch 6 controlled by a spring 633.
The levers 629 have suitable bearings to receive a shaft b provided with
pinions 635, one for each segmental rack 627.
The shaft 63 has mounted on it loosely the hub of an arm 636 having a
pin 637 entering a hole in the part of the guide plate 28 attached to the upper
end of the lèver 629, and said shaft, at the right hand side of the hub of said arm,
has fixed on it a collar 638.
A spring surrounding said shaft 64 acts normally to draw the said shaft
toward the left viewing Fig. 1, keeping the pin 637 in the hole in the said guide.
During the time that the spinning frame is spinning yarn and winding the
same, the segmental bars 627 stand in their lowered positions, leaving the
clamps 20 down in position nearly opposite the bobbins being wound, and when it
is desired that the clamps shall engage and remove the caps 33, or it may be a
flyer instead of a cap, then the operator engages a suitable hand wheel on the
shaft 6, turns it, causing the gears 63 in engagement with the teeth of the rack
bars 67 to elevate the cap clamps and then the rock-shaft is raised, whereupon
the roller stud w² rises in the said slot and meets the switch 62 which acts to
quickly turn the clamps toward the caps, forcing the clamps onto and so as to
embrace the caps firmly, said caps engaged by the said clamps being removed
from the upper ends of the spindles as the rock shaft e continues its rising
movement.
Fig. 8 shows the cap removed from the spindle and partially elevated, but the
said cap will in practice, be carried up above the rolls A5 or until the roller
stud warrives in the upper end of the cam slot 631.
The clamps 20 hold the caps 33 firmly, and when the rock shaft is again
lowered at the proper time, the full bobbin in the meantime having been removed
and an empty bobbin having been applied to the tubes on the spindles, the said
caps are put upon the tops of the spindles, and after the rock shaft has arrived
in its lowermost position and the levers 629 have been moved to the left viewing
Fig. 8, to pull the clamps laterally from the caps, the operator engages the
arm 66, moves it to the right, thus removing the pin 677 carried by said arm from
underneath the rack bar 627 where it stood to hold up said rack bar during the
operation of doffing, the removal of said pin from underneath said rack bar per-
mitting the rack bar to descend again into its normal position.
During the descent of this rack bar its teeth remain in mesh with the teeth
of the said gear 63, the teeth of said gear being long enough to remain in mesh
with said rack bar, notwithstanding the longitudinal movement of the gear with
the shaft 6, the spring 63 permitting this movement of the shaft b
I will now describe the action of the clamps for engaging the full bobbin and
removing the same from the tube on the spindle.
These clamps I have lettered 460; one of them is shown in plan and detached
in Fig. 6, and it is composed of two concaved jaws carried each by an arm mounted
to turn on a stud screw in the underside of an arm 21 attached (as by a
suitable screw) to a bar h23, said arms having each a suitable stud or groove with
which are connected the opposite ends of a spring hol, said spring normally acting
to keep said jaws closed, but permitting them to yield as the acting free end of
said jaws meet the surface of the wound bobbin as the said jaws are being moved
toward the said bobbin to grasp it frictionally.
The bar 3 carrying said clamps is mounted on the upper end of a suitable
arm pivoted at (26 on a lever pivoted at 28 on an arm of a hub 2 loose on
the shaft e, the lower end of said lever 27 having a slot which is entered by a
bolt 30, said bolt serving to secure said lever in any desired adjustable relation

page_text: to the lever h mounted loosely on the rock shaft e6 and having the roller or other
stud 15 entering the cam slot in the cam plate h¹.
The lever 7 is adjusted, when desired, to normally keep the front edges of the jaws
or clamps substantially close to the surface of the wound mass of thread on the
bobbins, so that when said clamps are moved to embrace and grasp the wound
bobbins, the extent of movement may be reduced to the minimum.
Assuming that the shaft 6 is in its lowest position and the stud 15 is in the
bottom of the slot in the cam plate h¹; then in this condition the clamp h60 will
stand a little below the spindle rail A2, and as the rock shaft eo is raised, the pin 15
soon arrives opposite the little projection 2, and as said pin travels through the
part of the slot marked the clamps 60 will be moved from the position Fig. 7
to the right, to engage the full bobbins, and as the rock shaft e continues to rise,
the said pin will rise through the part 4 of said slot, the clamps
at such time, in engagement with the full bobbins, acting to lift
them vertically off from the tubes and spindles, the caps having been
previously removed, and finally, when the full bobbins have been fully removed,
the pin 15 passes the free end of the switch c35, and immediately thereafter the
weight of the full bobbins removed from the tubes and spindles is sufficient to
cause the levers 7 and h to turn on the rock shaft ef until the pin 15 meets the
straight side 36 of said cam plate.
Now it has been described that the empty bobbin carrying clamp moves to the
right to bring its bobbins into position opposite the spindles from which the full
bobbins have just been taken, and during this movement the bar 3 carrying the
full bobbin clamps, they containing full bobbins, is also moved with it to the
right, the jointing of the lever 25 to the lever 27 permitting of this movement.
The main shaft D is supported in suitable bearings D' from the bottom rail A³.
This shaft may be driven by power in any usual manner to operate the machine,
so that it will rotate a certain number of times in one direction, and then it may
be reversed to rotate a certain number of times in the opposite direction.
This shaft has a pinion D2, and when said shaft is rotated to move the pinion
in the direction of the arrow near it in Fig. 9, the rack D³ carrying the rock
shaft e is raised in order that the different levers and devices carried by it may
be raised in the act of removing the caps and taking off the full bobbins, and
when the shaft is lowered, the empty bobbins may be put on and thereafter the
caps put in position on the tops of the spindles.
To do this, the shaft D has substantially two rotations in one direction and
then two rotations in the opposite direction.
This shaft in practice is put under such control that it may be stopped at any
position, no matter what its direction of rotation.
The spindles B³ are confined to the builder rail in novel manner.
Usually each spindle has been held in place by a set screw inserted in the rail,
its end acting against the spindle.
Herein each spindle has its lowest end provided with a screw thread 101 shown
in Fig. 8, which is screwed into a threaded part of a split or clamping nut 102
provided with a clamping set screw 103 which may be set up to hold the lower
end of the spindle in adjusted position.
The nut 102 has adjustably attached to it by a set screw 105 a lipped finger 104.
The spindle may have its foot set in the threaded hole 106 and the spindle may
then be put up through the hole in the builder rail until the nut meets the
underside of the said rail and the lipped finger will then be confined in position
with its lip on the upper side of the rail, and the spindle when adjusted to put
its top at the proper level will be held firmly by turning in the set screw 103.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
1: The use in a spinning machine having a series of dead spindles, carrying

page_text: bobbin receiving tubes, of a bar having a series of clamps in which are placed a
series of empty bobbins, said clamps normally occupying a position out of line
with relation to said spindles and their tubes, said bar and its clamps being
movable longitudinally to put the clamps in line with said spindles and to there-
after carry said clamps toward said spindles in order that the bobbins held by the
clamps may be put on to the spindles and their tubes, substantially as described.
2: The use in a spinning machine having a bar provided with a series of
clamps to hold empty bobbins, of a secondary bar occupying a position parallel
with relation thereto, said two bars being united together by a roll-and-slot con-
nection, and a lever, and means to operate it to slide said two bars in unison in
the same direction, and another lever and connections to move the bar carrying
said clamps laterally with relation to the secondary bar and toward the spindle,
to place the bobbins carried by said clamps upon the spindles, substantially as
described.
3. The use in a spinning machine having a series of spindles of a bar having
a series of clamps, each clamp containing a lever provided with a finger, said
clamps holding each an empty bobbin, and means to actuate said bar and clamps
to place the bobbins carried thereby on the tops of said spindles, the fingers of
said clamps, as the clamps are being pulled off laterally from said bobbins after
they have been applied to said tubes and spindles, effecting a partial rotation of
said bobbins on said tubes, to enable the notches in the heads of bobbins to engage
the driving lugs of the tubes, substantially as described.
4: The use in a spinning machine having a guideboard or device to hold the
yarns, and having a series of dead spindles, carrying tubes to receive bobbins ;
of a series of clamps to engage a series of filled bobbins and remove them from
said tubes and spindles; and a thread catcher to engage the threads between said
full bobbins and said guideboard, substantially as described.
5: The use in a spinning machine having a guideboard or device to hold the
yars, and having a series of dead spindles, carrying tubes to receive bobbins; of
a series of clamps to engage a series of filled bobbins and remove them from said
tubes and spindles; and a thread catcher to engage the threads between said full
bobbins and said guideboard, and a series of empty bobbin clamps, means to
carry and actuate said empty bobbin clamps to apply said empty bobbins to the
tubes and spindles after the removal of the full bobbins, and cause the head of
each empty bobbin to clamp the thread while held by said thread catcher, the
latter bending the threads about the tubes preparatory to the descent of the
bobbins into driving position, substantially as described.
6. The use in a spinning machine, of a bar having a series of clamps each
having a spring jaw, and a stop, the bobbins carried by said clamps being seated
on said stop and held between the jaws of said clamps by means of a suitable
spring, substantially as described.
7: The use in a spinning machine having a series of dead spindles, and a series
of bobbin driving and carrying tubes mounted thereon, of a thread catcher, means
to move it from its inoperative position downwardly across the vertical path of
said spindle, such movement of the thread catcher causing the thread engaged by
it to be partially wrapped or bent about said tubes, substantially as described.
8: The use in a spinning machine having a series of separators, and a series
of spindles provided with bobbin receiving tubes, of a thread catcher having a
movement from one toward the other of said separators, to thereby engage the
threads located between said separators at one side of the spindles and tubes, and
carry it to the opposite side of said spindle and tube, substantially as described.
9. The use in a spinning machine, of a clamp carrying bar or rail, a series of
arms having guiding loops and secured to said bar or rail, a series of clamps con-
sisting each of two levers pivotted at their extreme outer ends on one of said arms,
said jaws or levers presenting at their inner ends concaved faces, said levers
moving freely in said guiding loops and being supported thereby near their con-
caved portions, substantially as described.

page_text: 10. The use in a spinning frame, of a series of spindles, a series of levers having
guides for the reception of rack bars, a bar or rail, a series of clamps carried thereby
and adapted to engage a series of caps used in connection with said spindles, a series
of rack bars depending from the bar or rail carrying said clamps and entering said
guides, and means to engage said rack bars to raise and lower them and their
clamps with relation to the levers carrying said clamps, substantially as described.
11. The use in a spinning machine for automatically doffing wound bobbins and
replacing them by empty bobbins, of the following instrumentalities, viz.:-a
series of dead spindles provided with bobbin carrying and driving tubes; a series
of caps supported by the tops of said spindles; a series of clamps to engage the
caps of said spindles; a series of clamps to hold a series of empty bobbins; a series
of clamps to engage the series of full bobbins preparatory to removing them from
the tubes of the spindles; and means to move each of said set of clamps in such
time and order that the caps will be engaged preparatory to lifting them from the
spindle, that the full bobbins will be thereafter engaged and removed from the tubes
of the spindles, the clamps carrying the caps being, during such operation, further
elevated, the clamps carrying the empty bobbins being then put into position
above and so as to place said bobbins upon the tubes of the spindles; means to
thereafter put the caps upon the spindles; a guideboard having a series of yarn
guiding eyes; a thread catching device to engage the thread between said guide-
board and said full bobbins while yet retained in the clamps which engage and
remove them from the tubes of the spindles, said thread catchers keeping the
thread in such position with relation to said tubes that the empty bobbins, as
they come into fully operative position on said tubes, may by their heads effectu-
ally clamp each of of said threads and hold them while the rotation of the tubes is
again started preparatory to spinning and winding the yarns upon the empty
bobbins carried by said tubes, substantially as described.
12. The construction and use of a clamp to engage and present empty bobbins,
said clamp having spring jaws which may yield as the bobbin is inserted into or
removed from said jaws, the other of said jaws having a stop to receive against
it the head of the bobbin, to thereby put the heads of all the bobbins at one and
the same level, substantially as described and shewn by the drawings.
