REVOLVING FLAT CARDS.

Our Cards are extensively used, and have won for themselves a high reputation for the quality and quant.i.ty of work they will do, the small percentage of waste made, and their durability and simplicity.

CHARACTERISTICS.

1--Rigid Bend, mathematically correct at all stages of wear of the wire.

2--Perfect concentricity of Flats to Cylinder. Cylinder Pedestals are adjustable.

3--Arrangements for adjusting Flats whereby accuracy to the thousandth part of an inch is obtained.

4--Better quality of yarn made from the same cotton, or equally good yarn made from cheaper cotton.

5--Card Clothing throughout is of best Hardened and Tempered Steel Wire, Plough Ground or Needle Pointed.

6--Patent Doffer Slow Motion, to facilitate piecing up of broken sliver.

7--Patent method of securing Clothing to the Flats; neatest, cleanest and most effective.

8--Patent Top Flat Grinding Arrangement for grinding from the working seating of the Flats.

9--Patent Flat Stripping Motion, which insures perfect stripping without damage to the Clothing on the Flats.

10--Back Bends or Circles for supporting Flats and preventing sagging and stretching of chains.

FLAT GRINDING MOTION

{63}

The following paragraphs briefly describe some of the points of advantage in the design and construction of our machines:

CYLINDERS AND DOFFERS are carefully balanced at a high speed and are ground after being turned, making a perfectly true surface for the Card Clothing.

GOOD SELVAGES--Both Cylinders and Doffers are clothed to the extreme edges, which prevents ragged selvages.

PROTECTION OF CLOTHING--The Doffers are provided with f.l.a.n.g.es to protect the Clothing, keep the edges firm and prevent the wire from being knocked down. Turned iron f.l.a.n.g.es on the Bends, and Segment Rings fixed to the inside of the lower part of the framing protect the edges of the Cylinders all the way round. The Doffers are made 1/8 in.

wider than the Cylinders in order to keep the edges of the latter clean.

PREVENTION OF ACc.u.mULATION OF FLY--The Segment Rings which are fitted close to the edges of the Cylinder project in such a way as to form a circle two inches larger than the diameter of the Cylinder. The Underscreens are attached to these Segment Rings, and this arrangement makes it impossible for fly to collect inside the Screens or about the edges of the Cylinders and Doffers.

ELECTRICAL TESTS--All Bends and Flats are tested at our works by special electrical apparatus, and this method of testing gives greater accuracy than can be obtained in any other way. More accurate Bends and Flats make closer settings possible.

PERCENTAGE AND ALL CASING-OFF PLATES are made of steel, polished inside and out, and bent to conform to the surface of the cylinder.

Each plate is set by gauge to the Cylinder, and the closing up of all air s.p.a.ces makes the acc.u.mulation of fly and cloudy carding impossible.

ADJUSTMENTS--Convenient adjusting arrangements with setting screws and lock nuts are provided for the Knife Plates, Doffers and Licker-ins.

These are all on the outside of the machine and are accessible and easily adjusted.

LICKER-IN SHIELDS--To prevent the acc.u.mulation of fly around the bearings and pedestals and the climbing of oil over the ends of the Licker-in onto the clothing, we supply stationary shields at each end.

UNDERSCREENS AND FEED PLATES--Our Underscreens are specially heavy and well constructed, and our Feed Plates are very carefully finished and fitted. We supply special Underscreens and Feed Plates for long staple cotton.

ADJUSTABLE CYLINDER PEDESTALS--The bearings for the Cylinders are made of phosphor bronze and the pedestals are adjustable either vertically or horizontally. This is a very important point, because the concentricity of the Cylinder with the Bends can be maintained as the bearings wear. The construction of our Card side is such that a very rigid support is given to the pedestals.

FLAT RELEASE--This is a very simple and convenient attachment to the Flat Driving Arrangement, which makes one of the worm gears loose on its shaft and enables the Flats to be easily turned by hand with a suitable wrench.

CONICAL BUSHINGS--The Cylinders are fastened onto the shafts by means of split conical bushings which are forced into place and prevent any possibility of the Cylinders working loose.
