Improvements in Spinning, Roving, and like Machines.
1, THOMAS FRANCIS DUNN, of 235 Dexter Street, in the City of Pawtucket,
in the County of Providence, State of Rhode Island, United States of America,
Mill Superintendent, do hereby declare the nature of my 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 has reference to improvements in that class of machines for
treating fibrous material in which the material is wound on to spools or hobbins,
either by the rotation of some other mechanism, as a flyer, to wind the material on
to a receiving device, or by the rotation of both of those parts.
The machines of this nature to which my improvements are particularly adapted
aie roving-frames so called.
The object of the invention is to simplify and render more practically operative
To this
the portions of a spinuing or roving machine as hereinafter claimed
end the invention consists in the peculiar features of construction and combination
of parts as will hereinafter be more fully described and pointed out in the
claims.

Sumulat numbers of reference designate corresponding parts throughout.
In roving machines the driving of the spindles and flyers positively, necessitates
a large amount of geauing and shafts between the main drive-shafts and these parts,
whereby much power is wasted in transinission.
To remedy these defects and others, the cone-diving mechanism, the building
devices, and the reversing and other mechanisms brought into use in operating
the machines, or in the doffing process, are heren sought to be perfected.
Spinning, roving and drawing frames are, it is thought, by the present improve-
ments of the spindle-tails and then corelative mechanisms brought to a higher state
of perfection in then functional relation to the material acted upon than as heretofore
coustructed
In the drawings 20 indicates one of the end samsons between which the
mechanism extends, being intermediately supported by smaller frames oi sambous.
On these smaller samsons is supported the table-top 21 the edge portious of which
form the roller-beams, and on the table-top is mounted the usual crecl-fiame 22
having the laterally-extending aims 23-23 and 24-24 between which the
bobbius a-a from the slubbing-frame are rotatably supported, so that the rove
may be drawn therefrom without stretching
The samson 20 is of box-like construction and in it, as well as in the first small
samson 25, is journaled the main-dive-shaft 26 provided at its outer end with the
tight pulley 27 and the loose pulley 28 At its inne end is the twist-gen 29
connected by the ule-pinion 30 with the gear 31 on the upper cone-shaft On the
cential portion of the drive-shaft, or connected therewith, is the differential-genr 32
of any usual construction, which connects by the gent 33 with the change-shaft 34,
suitably mounted, and through the geat 35 with the spindle-diving mechanism to
drive the spindles at a speed determined by the location of the cone-belt on the
Within the samsous 20, to the shaft 26, the flyer-dive-gear 36 18 secured,
this gear connecting through a suitable train of gears with the two rows of flyers to
drive them positively and at a constant speed
coues.
On the upper cone-shaft 37, which is journaled in the small samsons and carries
the upper couc 38, is the gear 39 which is connected through the usual gears
with the front diawing-tolls 40-40 that these may be positively driven.
The rail-lifts 42 are pivotally mounted on studs in the samsous and have lever-
atms 43-43 which project under and support the rails, in operation one rail 18
raised as the other is lowered and vice versa, by this arrangement one rail is mado
to balance the other and the heavy weights used to counterbalance the rail in the
old system are dispensed with. A rack 44 is attached to the lower portion of the
rail-lift and is engaged by the pinion 45 on the rail-lifting-shaft 40 extending
through a portion of the machine in bearings and furnished with the gear 47,-any
number of the tail-lifts may be used.
In the samsons 25 and 25' is mounted the shaft 48 provided at its near end with
the atm 49 On this shaft is 1otatable the sleeve 50 Laving lateral arms, as 51, in
which the lower cone-shaft 52 caying the lower cone 53 is journaled, the cone-
shaft also extending though a radial slot 54 in the samson 25, whereby it may
swing on the shaft 48 and though a collar on the end of the arm 49, being
provided with the gear 55 beyond this collar. On a stud in the arın 49 18 Journaled
the idle-gear 56 which takes into the gear 55 of the lower cone-shaft.
The change-shaft 34 is journaled suitable bearings having the gear 33
engaging with the differential or compound 32, the bevel-gear 57 through which
connection is made to the tiaveise-reversing incchauism and the gear 58 inter-
meshing with the idle-gear 56. The shafts 34 and 48 being in axial alignment it
will be seen that the cone-shaft 52 may be swung upward or downward without
disengaging its gear 55 from the gear 58 of the change-shaft 34.

page_text: The cones 38 and 53 are au auged in the usual manner, that is, with the large
diameter of one opposite the small diameter of the other For transmitting the
motion of one to the other an endless-belt 59 is used, this belt is controlled by a
shipper 60 mounted on the cone-1ack 61 reciprocally supported in the guide 62 and
having the projection 63.
At the faithe end-portion of the guide 62 is movably mounted the reciprocating-
od 64 held in its forward position by the spring 65 bearing against the projection 66
on the back of the guide and against the iod, and having the finger 67 adapted to
be engaged by the projection 63 of the rack, and the step 68 for supporting the
shipper-weight 69 connecting with the automatic shipper-iod 70 by means of the
pivoted bell-crank-lover 71 so that the dropping of the weight 69. by the removal
of the step 68, will actuate the rod 70 to ship the dive-belt from the pulley 27 to
that marked 28 by means of the shipper-lever 72,-the connection between the
rod 70 and the shipper-lever allowing sufficient play to permit of the shipper-
lever being moved in this same direction by hand without affecting the weight 69
oi its level.
The connection being now established from one cone to the other it will be seen
that as the drive-shaft 26 is rotated the upper cone 38 is driven at a constant speed
through the gears 29, 30 and 31, at the same time the front roll will be likewise
rotated through the gear 39 and the top-roll-gears, while the flyer-driving-mechanisin
will be similarly operated through the gear 36 on the duve-shaft. In thus driving
the diawing and winding devices the usual provision for reducing the speed of the
bobbins in proportion to the increase in diameter of the same by the yarn wound
thereon is necessary, this being effected by the shifting of the belt to dine fioni
the larger diameter of the upper cone and the smaller diameter of the lower cone
to the smaller diameter of the upper cone and larger diameter of lower cone and
to utilize this change of speed through the change-shaft 34, the gears between this
and the lower cone, thence through the compound or differential gear 32 to the
gear 35 and through the same to the spindle-driving mechanisin.
At the further end of the upper cone-shaft 37 is secured the bevel gear 73 which
intermeshes with the bevel-geai 74 on the upper end of the dog-shaft 75. This
shaft 75 is vertically journaled in bearings and is furnished with the gear 76 and the
arm 77 which swings around the axis of this gear,-on the aim is journaled
the gear 78 to which the tension-gear 79 15 secured, as the tousion-gear takes into the
cone-rack 61 and serves to opeinte the same to determine the speed of the spindles,
it will be evident that the size of the tension-gear is of material importance to
the tension excrted by the spindles on the roving
To effect the positive removal of the tension-gear 79 from the rack, I provide
the outer end of the aim 77 with a pin 80 which engages in the cam-groove 81 of
the cam 82 which is jounaled in the bracket-arm 83 secured in the fiame and is
otated by the hand-wheel 84, whereby the atm 77 is shifted to disengage the
tension-gen from the tack, while the cam-groove is of such a shape as to lock the
pin 80 at both ends of the groove
The releasing of the tension-gear from the cone-ack is necessary when the
cone-rack is shipped backward at the time of dofling. To accomplish this the
lower cone must be first raised from contact with the coue-belt
For this purpose
I furnish the lower cone-shaft at the larger end of the coue with the ratchet 85
and between this ratchet and the cone I place the bearing 6 which is called by
the pivoted lever 87. Below the lever 87 is pivoted the bell-crank-lever 88 one
arm of which bears against and sustains the lever 87 while its depending arm is
engaged by the cam 89 mounted on a shaft jou naled at the lower portion of the
machine and baving a square end 90 with which a crank may engage. The rotation
of the cam in one duection serves to actuate the levers 88 and 87 to raise the cone
and its ratchet 85 to a position where the pivoted-pawl 91 may engage the ratchet
and prevent the notation of the cone in the duection indicated by the arrow in
Figure 9 of the drawings
When the lower cone has been thus elevated and is sustained, a key or crank is

page_text: applied to the end 92 of a shaft Journaled in bearings adjacent to the cain 89 and
having a bevel-gen 93, the rotation of this shaft and gear is imparted though the
bevel-gear 94 to the vertical-shaft 95 and its gear 96 to 1eciprocate the rack
backward, it being understood that at this time the tension-gear 79 18 disengaged
from the lack.
Returning now to the dog-shaft 75, and referring to Figure 5 of the drawings,
it will be seen that the gent 74, at the upper end of the shaft, has spaces 74-74
which are not provided with teeth, when, therefore, this gear is rotated sufficiently
to bring either of these spaces opposite to the gen 73 the connection between
these gears will be broken and the rotation of the gear 73 will have no effect on
the gear 74, thus occurs twice in each rotation of the dog-shaft 75 and its gear 74.
To rotate the shaft 75 when the teeth of the gear 73 arc in the spaces 74' of the
gear 74, secure to the lower end of the shaft 75 an eccenti ic 97 having the pins 98
and 99 extending therefrom. To the samson 25' s pivoted an arm 100 having a
curved bearing-end 101 adapted to alternately bear on the pins 98 and 99 and
though the spring 102 to exert a pressure thereou tending to rotate the dog-shaft,
the curving inner edge of the arm serving as a cam riding on the pins alternately
to throw the free end of the aim outward in position to engage the pin as the
dog-shaft is positively notated from the gear 73. Embinuing the eccentric 97 18
the strap 108 basing the connecting-1od 104.
It will be evident that it is necessary to regulate the intervals at which the
spring 102 is permitted to act on the aim 100 and thence through the pins to
rotate the dog-shaft and through the connecting-10d 104 to reverse the tiaverse
motion, or the traverse would be limited to the time of the half rotation of the
dog-shaft 75 and the traveise being constant no tapening of the bobbins would
occur.
To regulate the rotation of the dog-shaft 75 I secure to the shaft the oppositely-
extending dogs 105 and 106 which aie adapted to be intercepted in the rotation of
the dog-shaft by the regulator. The regulator consists of a bracket 107 supported
by an arm which is secured to a portion of one of the spindle-rails or other
tiaversable part of the machine baving an up and down movement equal to that of
the spindle-iail, or soine proportion theroof In the bracket 107 18 mounted a shaft
having the upper square portion 108 and the lower oppositely-threaded portions 109
aud 110,-
-on these screw-threaded portions are the intercepting fingers 111 and 112
which, by the rotation of the screw-threaded shaft, work in opposite directions
thereon, being prevented from rotating with the shaft by the shape of the bracket.
The square shaft 108 is fice to move upward or downward in a squaro bearing of
the gear 113 but is rotated by this geni which is suitably journaled and is duiven
through the gears 114 and 115, the one engaging in the gear 113 while the other
interineshes with the cone-inck.
It will be seen that as the lack is duiven for ward it will cause the gears 115,114
and 113 to 1otate, thus rotating the shaft 108, and, through the action of the
oppositely-extending screw-threads, the fingers 111 and 112 will be gradually
drawn together so that at each rotation of the shaft 108 the obstruction to move-
ment of the dogs 105 and 106 is reduced, the building of a layer of yarn on the
bobbins being in process while the dog-shaft is thus held from rotation.
When the dogs 105 and 106 are allowed to sing past the regulating fingers 111
and 112, the spring 102 tends to rotate the dog-shaft, through its connection there-
with, and, by means of the eccentric 97 and its strap 103 the connecting-rod 104
is reciprocated and nets to reciprocate the shaft 116 carrying the broad-faced
pinion 117 in engagement with the pulley 47 of the rail-lifting shaft
On this shaft 116 are also secured the oppositely-beveled gears 118 and 119,
which are adapted to be alternately engaged by the bevel-gear 120 to drive the
shaft 116 alternately in opposite directions and through tho gears 117, 47 and 45
and the shaft 46 to transmit this change of direction to the rail-lifter 12, the gear
120 being in turn driven though the gear 121 taking into the gear 57 so that the
rail-lift is opeinted in a reduced degree at each leversal thereof.

page_text: The creel arms 24-24 extend beyond the creel-boards 178-179, so as to form
supporting bearings on which the shipper rods 180-181 slide freely, the shipper-
rods are attached at the driving end of the frame to the shipper lever 72
The
covers 122-123 to protect the shipper-iods from lint and dirt extend the length
of the creel and have openings 124 at intervals through which the handles of the
shipper rods project the upper edge of the covers are attached to the creel-
boards 178-179, the lower edge being held by the flanges 182-183 on the ends of
the creel-arms 24-24 This location and arrangement dispenses with stands levels
and other supporting parts used in the old way and allows one fourth more roving
On
to be placed in front of the frame where it is more accessible to the attendunt
the outer portions of the table-top 21, which form the roller-beams, are mounted
the roller-stands 125 of the usual construction and carrying the top and under rolls.
Bearing on the reduced portions of the ical and intermediate top-1olls 126 and 127
une the saddles 128 provided with shortened sturups 120 having eugagable portions
at their lower ends. On the reduced portions of the front rolls 130 rest the hook
portions 131 of the curved sin rups 132 also having engagable lower ends, and in
these ends of the strups are engaged the ends of the yoke 133 having a series of
perforations to receive a pin on pivot by means of which the connecting-luk 134
may be adjustably secured to the yoke 133 to bring a strain at the center of the
yoke or at either end.
Nem the outer portions of the table-ton arc secured a series of slotted studs 135
in which the hooked ends of the levels as 136 may engage, these levers extend
through the links 134 and are furnished with weights 137 adjustable on the levers
to uciense or diminish the pressure on the saddles
Formed in part with the saisons, or secured in the machine in any suitable mannerat
both sides, are vertical guides as 138, and traversably mounted in these guides are
bracket-plates as 139,-to the bracket-plates are pivotally secured the eais 140 of
the hollow spindle-1ails 141, these rails have also the depending arms 142 provided
with roller-bearings 143 which ride on the armis 43 of the ail-lift 42, the said arms
Leing adapted to serve as a track, as many of these tail-lifts being employed as is
necessary to effectually support the spindle-tails. To each of the bracket-plates 139
18 suitably seemed au arm 144 having a ring-bearing 145 at its outer end and
in this ring-bearing is rotatable a disk 146 in which is eccentrically secured the
shalt 147 having a squared end to receive a key or crank; this shalt being jominaled
in the cais 148 of the spindle-tail, it will be evident that by the sufficient totation
of the shaft and of the eccentric-dishs 146, the lower portion of the spindle-rail
may be drawn towards the samsons, causing the tipping outward of the upper
portion of the ail and the spindles carried thereby.
The spindle-rails are generally circular cross-section but may bo of any
desuable shape, then naiiow portion, from which the attaching eais extend, is
preferably of strong and durable construction, while the front portions may consist
of removable couvex-covers 140 by the opening of which access may be had to the
Interior of the rail. To the lower portion of the rail is secured a series of bearing-
brackets 150 in which the shaft 151 18 Journaled,-at the upper portion the rail has
the thickened portion 141' through ninch perforations are formed to allow for
the working of the upper portion of the spindle-geni Connecting this upper
portion 14 with the lower portion and the inner side of the rail 141 are the
Hanges or binces 154 disposed at intervals along the rail and adapted to strengthen
the same transveisely The rear o main wall of the spindle-inil is perforated at
inter vals, the perforations being covered by the plates 156 pivoted to the rail and
having projections or finders which enter the perforations when the plates 156 are
swung into positions to close the perforations, the projections serving as locking
devices to hold the plates 156 in this position, immediately below the perforations
covered by the plates 156 and extending into the same are secured the inclined
oiling tubes 155 formed in part with the spindle holster-beaung and oil-wells 153
which are axially disposed with reference to the perforations in the portion 141 of
the 1ail.

page_text: In the bolster bearings 153 are journaled the spindles 157 provided with the
spindle-gear 161 the upper portion of which is cone-shaped and extends though
perforations in the portion 141' of the rail and is provided with the pin 158 to
iotate the bobbin, the spindle-gear 161 being duiven by the gear 152
This mangement allows the bobbin to rest on and be rotated by the spindle-gear
and dispenses with the bobbiu-gear and long extra bolster and allows a spindle to
be used that is but one-fifth the weight of the old spindle.
The diving mechanisin between the shafts 151 and the gear 35 is of the usual
character consisting in gears journaled on movable bearings so that at all times
dining the traverse of the spindle-rails, driving connection is maintained with the
shafts 151 and the beveled-gear 152 mounted on thus shaft
By reference to the drawings, Figure 10, it will be seen that the spindle-tail is
adapted to contain the spindle-shaft with its driving-connection to the spindles and
to protect them from flying lint and dust which generally surrounds machines of
this character when in operation.
Secured to the machine, intermediate the spindle-tails and the diawing-rolls, is a
flyer-rail, or support for the flyets, which is primarily adapted to support the flyers
in operative positions independent of the spindles, this rail is preferably fixed, but
may be arranged in any suitable manner to accomplish the objects for which the
machine is designed.
In the preferred construction the flyer-1ails are secured just below the roller-
beams having inclined portions 162, to serve as covers to protect the flyer-driving
mechanism, and the rails proper 163 having the depending bearing-sleeves 164 and
lips 165 also serving to protect the diving mechanism.
Below the inclined portion 162 of the flyer-rail the bearing-brackets 160 are
secured to the machine-frame and in these brachets are Jomualed shafts, as 167,
driven through trains of gears 168-168 from the gear 36 on the main drive-
shaft 26. On the shafts 167 are mounted bevel-gears 169-169 which engage in
the pinions 170 of the stud-gear 171 rotatably mounted on the studs 172 which are
secured in the inclined portion of the flyer-rail
The flyers are of the usual construction in so far as they have hollow legs
through which the roving may pass one of the legs of each flyer being provided
with a compiesso-arm. In its preferred form the flyer 173 has an axially-disposed
tubular guide 174 which is journaled in one of the bearing-sleeves 163 of the flyer-
rail and having an upper flange 175 serving as a beating to rotatively sustain the
flyer in position.
To the guide 174 is secured the cup-shaped-gear 176 which cambiaces the lower
portion of the beamng-tube 163 while its pinion-teeth utcimesh with the
geal 171.
Below the gears 176 is a dip-tiough 177 through perforations in which the
guides 174 extend; this trough being adapted to catch any lubricant from
the gears 171 and 176 to prevent its falling on to the Loving on the bobbins
