CARD CLOTHING.

The English system of numbering Card Clothing is now generally used by Cotton Mills. We give below the numbers and points per square foot:

Numbers Pts. per Square Foot 80s 57,600 90s 64,800 100s 72,000 110s 79,200 120s 86,400 130s 93,600

The following numbers are generally used for Cylinders: Coa.r.s.e, heavy work, 80s and 90s; medium to fine work, 100s and 110s; fine work, 120s and 130s.

Doffers are usually 10 numbers higher or finer than Cylinders.

There is considerable variation in the Clothing used for Tops. Some prefer thinner set than the Cylinders, others about the same as the Cylinders, and a few the same numbers as the Doffers.

DRAWING FRAMES.

The Howard & Bullough Patent Electric Stop Motion Drawing Frame has proved one of the most successful machines ever invented, and there are large numbers of deliveries at work in every Cotton Spinning country.

We build both Electric and Mechanical Stop Motion Frames, but the great majority of our orders are for machines with Electric Stop Motions.

The quality of sliver produced by these machines cannot be surpa.s.sed; a great saving in waste "single" and roller laps is effected, and production is increased.

Machines stop:

1st--When sliver breaks at back or a can runs out.

2d--When top or bottom front roll laps up.

3d--When sliver breaks in front.

4th--When cans are full.

5th--When back electric roll or clearer laps up.

On account of the positive and quick action of the Electric Stop Motions, machines can be run at a much higher speed, in case of necessity, than Mechanical Stop Motion Frames.

The tops of Electric Stop Motion Frames, being free from the many small parts and projections which are a necessity on Mechanical Stop Motion Frames, are much more easily kept clean, and "fly" is not carried into the sliver, besides which a great many delicate and troublesome Mechanical Stop Motion parts are done away with.

FRAMING AND CONSTRUCTION--The machines are built with low, rigid framing. Can tables set into or on top of the floor.

BOTTOM FLUTED ROLLS are made in one length and are irregularly fluted so as to prevent cutting of top rolls. The usual diameters are 1-3/8 in. front, 1-1/8 in. second, third and fourth lines.

TOP ROLLS are usually 1 in. dia. on iron. The front line can have Loose Boss or Loose Ends; the latter are now in extensive use and are generally preferred.

ROLLER STANDS are made with separate adjustable slides or bearings, so arranged that the top and bottom rolls move together when setting for different lengths of staple. The Roller Stands and Slides have bra.s.ses cast in them for roller bearings.

CALENDER ROLLS are made of steel, turned, ground and polished.

DRAFT GEARING--All Draft and Roller Gears are cut. Changes of Draft are very easily made, and the gearing is well protected with polished covers.

COILERS are made for cans 36 ins. long, 9, 10, 11 or 12 ins. dia. as required.

TENSION--Our fine pitch gearing for the take-up of the sliver between the fluted rolls and the Calender rolls enables a nice adjustment to be made for either ordinary or metallic rolls, and reduces the stretching, sagging and breakage of the sliver, preventing stoppage and waste.

TRUMPETS--These are made separate from the calender plates and can easily be taken out. This method is an advantage over the old style, as trumpets wear in time and when worn do not sufficiently condense the sliver. With this system they can easily be replaced.

BACK GUIDES for both Electric and Mechanical Stop Motion Frames are designed so as to separate the slivers and keep kinks from going into the rolls, thus preventing lumpy and uneven work.

CLEARERS--Both top and bottom rolls have Clearers. We apply a patented and very successful Clearer to the Calender rolls which prevents fly from sticking to them and being carried in to the sliver.

WEIGHT RELIEVING MOTION--This is applied to all frames for taking the pressure off the rolls when the frames are stopped.

All rolls are weighted separately. Usual weights are 20 lbs. front line; 18 lbs. second line; 16 lbs. third line; 14 lbs. fourth line.

TRAVERSE MOTION is applied to all frames with leather covered top rolls.

METALLIC TOP AND BOTTOM ROLLS--The front bottom roll is usually 1-3/8 in. dia., and the other three lines of bottom rolls as well as the top rolls, all 1-1/8 in. dia.

Front and second lines are usually 32 pitch; third line 24 pitch and back line 16 pitch. The top rolls have Loose Ends. Weights usually 14 lbs. on all lines.

ERMEN TOP CLEARERS--The cloth of these Clearers revolves over 2 rolls (one of which is positively driven) and comes in contact with all the top rolls. This revolving clearer is placed inside of our top clearer cover, and is stripped by a Comb through an opening in the top of the cover. This clearer meets with great favor in fine mills, where combed long staple cotton is worked.

DRIVING PULLEY AND SPEED--The Driving Pulley on the Bottom Shaft is usually 16 in. dia., 3 in. or 4 in. face and can be placed at either end of the frame. The usual speed of this shaft is 250 r. p. m., which gives a calculated speed of 363 r. p. m. of Front Roll. One rev. of shaft equals 1-5/11 of Front Roll.
