TRAVELLER TABLE FOR RING SPINNING FRAME.

The speed, kind of cotton, etc., affect the weight of traveller, and consequently it is impossible to make up a table to cover all conditions, but the sizes given above will serve as a basis to select from. Lighter travellers should be used for higher speeds and vice versa. Each 1,000 revolutions of spindle makes a difference of one or two numbers in travellers.

REELS.
Reels are usually made with 50 or 60 spindles each, but can be made either longer or shorter. The common gauge is 3-1/2 in., the length of which with 50 spindles is 16 ft. 8-1/2 in. and width 3 ft. 9 in.
Machines are made for 54-in., 60-in., 72-in. and 90-in. skeins, usually 54 in.
Driving pulleys are 12 in. x 2 in.
The usual speed with 54-in. swifts is 130 revs. We give below production table for 54-in. skeins.

RING TWISTERS.
FOR DRY OR WET TWISTING.
Our Ring Twister resembles our Spinning Frame, both in construction and design, and the descriptive matter on pages 140 and 151 apply to this machine.
The marked success of our Spinning Frame led us to build a Twister embodying the same improvements and special features which have been so much appreciated. All parts are machined, and are interchangeable.
LOW FRAMING AND HEAVY RIGID CONSTRUCTION--The frames are built very low, are extra heavy in all their princ.i.p.al parts and are designed and constructed so as to stand high speeds without vibration, thus preserving the spindles, insuring light running and reducing the cost of repairs.
DRY AND WET TWISTING--We build machines for either Dry or Wet Twisting.
When for wet work the bottom and top rolls are covered with bra.s.s, and bra.s.s troughs are provided for the water. The yarn is submerged by means of gla.s.s rods which are easily raised or lowered.
ARRANGEMENT OF ROLLS--Machines are built with any of the following arrangements of Rolls:
Single Line Bottom Rolls, and Single Line Top Rolls.
Double Line Bottom Rolls, and Single Line Top Rolls.
Double Line Bottom Rolls, and Double Line Top Rolls.
SPINDLES--Any of the improved modern high-speed spindles are supplied as required. We do not make any Twisters with common or old style "Two Rail" spindles.
KNEE BRAKES are furnished when required.
GAUGES AND RINGS--We build machines from 2-1/2-in. gauge with 1-1/2-in.
rings up to 5-1/2-in. gauge with 4-1/2-in. rings. Any desired form or style of ring will be furnished. All of these rings are made from high-grade steel of special a.n.a.lysis, hardened by improved methods and accurately finished.
