SECTION OF DRAWING FRAME SHOWING ELECTRIC STOP MOTIONS
{99}
EXPLANATION OF ELECTRIC STOP MOTIONS.
Our improved Magneto or Dynamo for producing current to operate the Stop Motions is designed on the "Induction" principle, so that the current is generated in the stationary winding, and no brushes or collectors are needed. This type of machine is very simple, requires little attention, and gives a steady current, no matter how much dirt, lint or oil collects on same.
The Drawing Frame is divided into two parts by means of insulations (indicated by the solid black portions of cut on opposite page). One part, shown with double cross lines, is connected to the Magneto through the down-rod A, and the other part through the down-rod B.
It will be seen that in the case of each Stop Motion the parts are kept from touching each other by cotton pa.s.sing between them (cotton being a non-conductor of electricity) or are brought into contact with each other by rollers lapping up or by the pressure of the cotton in the full cans.
The machine stops when the electric circuit is completed, allowing the current to flow through Magnet T, which attracts finger U into engagement with Revolving Clutch V, and by a mechanical arrangement shifts the belt on to the loose pulley.
As the frame stops, the part X forces the finger U away from the Clutch, and the current is broken by the piece Y which moves out of contact with the spring Z. When the frame is running, Y is in contact with both the springs Z and J. As the machine stops, the movement of Y takes it out of contact with Z, but J should always press against Y.

STOP MOTION No. 1--C is the top electric roll which rests in Cap Bar D, and E is the bottom electric roll. As long as the sliver remains between the rolls they are kept apart and there is no circuit. When the sliver breaks or a can runs out the rolls come together and the frame knocks off.
STOP MOTION No.2--The Top Clearer Cover H has a screw K on the under side. If the cotton laps around the top or bottom front roll, the top roll is lifted and comes in contact with screw K, which completes the circuit and the machine stops.
STOP MOTION No. 3--The cotton sliver prevents the calender rolls L and M from touching each other. If the sliver breaks, the rolls touch and the machine stops instantly.
STOP MOTION No. 4--When the cans at the front are full and cotton presses against the coiler top N, it is lifted into contact with the spring O, and the circuit is completed, stopping the machine.
STOP MOTION No.5--The Underclearer P presses against the bottom electric roll E. In case the cotton laps around E or P, the screw Q is lifted and touches the Back Plate G, completes the circuit and the frame knocks off.

SLUBBING FRAME (RIGHT HAND)
{103}
SLUBBING, INTERMEDIATE, ROVING AND JACK FRAMES.
These frames are so well known to the users of Cotton Machinery that no general description is necessary. They have extra heavy framing, are made entirely by special tools, and all parts are exact duplicates. They are of superior construction and finish, and will stand the highest speeds without vibration or breakage. They contain many valuable patented improvements, some of which are described below.
PATENT SWING--Well supported and with one (large) Carrier Gear only.
IMPROVED DIFFERENTIAL MOTION--This motion effects a great saving in power, wear and tear, and gives more accurate winding and consequently evener and better work. See page 106.
IMPROVED LAY GEARING dispenses with all bevel change gears, gives two change places instead of one, is simple and convenient, and allows free access to the main gearing. See page 109.
IMPROVED METHOD OF LIFTING AND LOWERING BOTTOM CONE DRUM--Both ends of the cone are raised or lowered together from the front of the machine.
The belt is kept at a uniform tension from one end of the cone to the other. A patent locking device secures the cone in its proper working position, after doffing, preventing all movement or vibration.
IMPROVED METHOD OF TIGHTENING THE CONE BELT does away with frequent taking-up. When slack, the belt may be tightened in a few moments by means of a Quadrant Bracket. Over 5 in. of stretch can be taken care of without re-piecing. A great saving is effected in labor, stoppages and cone belts.
WINDING BACK THE RACK AND CONE BELT is done from the front of the machine.
IMPROVED SYSTEM OF BALANCING THE TOP OR BOBBIN RAIL--This rail, with its gearing, collars, bobbins, etc., is now supported under its center of gravity by a set of levers, thus relieving the slides and racks of this weight. This system prevents friction and wear of slides, also the tendency to dwell at the changes of the traverse both top and bottom.

ROVING FRAME (RIGHT HAND)
{105}
If slides wear, the Long Collars tilt forward, the top rail, spindles, bobbins and flyers vibrate, causing bad work and loss of production.
This is prevented by our improved system.
PATENT REVERSING AND LET-OFF MOTION entirely prevents the roving running over the ends on the changes. The speed of the bobbin changes simultaneously with the reversal of the lifting rail and thus overcomes the liability of stretching the roving.
FULL BOBBIN STOP MOTION is very effective in its action and prevents overfilling the bobbins. The frame cannot be started after the completion of a set until doffed and the rack has been wound back.
IMPROVED TOP CLEARERS--These are made of polished steel, very light and easy to clean. The hinging is so arranged that any clearer can be easily removed.
LONG COLLARS OR BOLSTERS are fastened in a vertical position by an improved method which prevents their working loose. They are bored throughout their entire length, thus reducing the liability of dirt acc.u.mulating inside and causing the spindles to bind.
PATENT RECESSED SELF-LUBRICATING SPINDLE FOOT--This has proved one of the most successful inventions, and is in extensive use. It ensures constant lubrication, prevents wear, and is easily kept clean.
BEARINGS INLAID WITH BRa.s.s--All Bobbin and Spindle Shaft Bearings, Roller Stands and Slides are inlaid with bra.s.s.
[Ill.u.s.tration]
DRIVING ENDS OF BOBBIN AND SPINDLE SHAFTS are case hardened and are in short lengths, so that they can be easily taken out even when frames are placed end to end with narrow pa.s.sages between them. This is a great convenience, as it avoids the necessity of having to remove a great many shaft gears. The shafts can be lifted out with the gears on them.
AUTOMATIC PANEL LOCKING ARRANGEMENT prevents the frame from being started if any of the gearing end panels are not in place.
