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: Coarse, 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 surpassed; 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.

{85}

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 brasses 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.

LENGTHS OF DRAWING FRAMES, 16-IN. GAUGE.

Above lengths are over all, including Driving Pulley. For widths, see Floor Plans, pages 88 and 89

Drawing Frames are usually made with 4, 5 or 6 deliveries per head or table, and 2, 3 or 4 heads per frame, but can be made with more or less deliveries per head, and more or less heads per frame.

The above figures are for Total Draft up to and including the 3-in. dia. Calender Rolls. When Graduated Pitch Metallic Rolls are used, and it is desired to figure drafts between them, the following equivalents are approximately correct:

1-3/8-in. dia. Roll, 32 pitch, taken as 11/6-in. or 1.83-in. dia. 1-1/4-in. dia. Roll, 32 pitch, taken as 10/6-in. or 1.67-in. dia. 1-1/8-in. dia. Roll, 32 pitch, taken as 9/6-in. or 1.50-in. dia. 1-in. dia. Roll, 32 pitch, taken as 8/6-in. or 1.33-in. dia. 1-1/8-in. dia. Roll, 16 pitch, taken as 10/6-in. or 1. 67-in. dia. 1-in dia. Roll, 16 pitch, taken as 9/6-in. or 1.50-in. dia.

{95}

PRODUCTION CALCULATIONS

The greater production with Metallic Rolls over Common Rolls for a given number of revs. is due to the meshing of the flutes, which increases the effective circum. of the rolls about 33 per cent. This accounts for the difference in the gears driving the Calender Rolls.

Short rules for production in 10 hours based on 20 per cent. allowance for stops, etc., and 1-3/8 in. dia. front bottom roll.

Common Rolls--.852 x R. P. M. of Front Roll x Wt. of Sliver in grains = Lbs. in 10 hours.

Metallic Rolls--1.126 x R. P. M. of Front Roll x Wt. of Sliver in grains = Lbs. in 10 hours.

GEARING COMBINATIONS, DRAFT CONSTANTS AND DRAFTS FOR MACHINES WITH 1-3/8-IN. FRONT ROLL.

The above constant and drafts are figured up to and including the 3-in. Calender Rolls. Draft Gear K is the usual change gear.

When making extreme draft changes the best results will be obtained by following the above arrangements of gearing.

{97}

TABLE FOR NUMBERING CARD OR DRAWING SLIVERS.

8.333/Wt. in grains of 1 yd. of Sliver = Hank. 8.333/Hank = Wt. in grains of 1 yd. of Sliver. 100/Wt. in grains of 12 yds. of Sliver = Hank. Refer to Table of Dividends, page 233. {98}

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 passages 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.

{106}

To facilitate making changes in the Lay Gears, we have provided two change places instead of one. Formerly it was the practice to change the gear on the end of the Reversing Shaft or the one between the Reversing Bevels.

In order to bring the change gears into a more convenient position and at the same time increase the range, we have introduced two additional spur gears. One of these is now the regular change gear, and is on a stud carried by an adjustable Quadrant Bracket. The short shaft carrying the bevel gears is now in a horizontal position instead of vertical.

{110}

Besides providing for two change places, this improvement dispenses with the Back Cross Rail and allows free access to the main gearing. Any part of the gearing can be taken out and replaced with ease.

There is no longer any necessity of changing any bevel gears. There are two spur gear changes, either of which may be used and which give a very wide range. The entire arrangement is very simple and convenient.

Other sizes of Spindles, Long Collars, Bobbin Gear Tops and Rolls will be supplied when necessary.

DRIVING PULLEYS are usually 16 in. dia., 3 in. face.
