REVOLVING FLAT CARDING ENGINE.

Appnaaon mea February 41927, seriarNo. 165,801, @man Great Britain February 1s, 192e.

These improvements relate to revolving lfiat carding engines wherein a greatly reduced number of revolving flats'are used in accordance with the system fully disclosed 5 in the prior Patent No. 1,567,541.

My invention is an improvement in or modification ot' the invention described in the said former Patent 1,567,541.

The object et the present invention is to produce a much simpler card which, whilst being cheap to inake, shall yet be equally et- .icient as compared with an ordinary revolving flat card with its full complement of flats, and shall occupy less over-all space than an ordinary card, and be easier to work as regards setting, grinding, etc. For instance the number of setting points can be reduced to two or three.

According to my present improvements I do not use two cleaning or combing mechanisms but only one, that is, a single cleaning or combing mechanism fed from an ordinary lap over a normal dish feed. By virtue oit the greatly reduced numb'er of flats this dish feed can be arranged appreciably alcove the level of the centre of the main cylinder so as to carry the taker-iny as close to the chain of flats as may be desirable in orderl that a back plate orsheet of ordinary narrow width, or even less than ordinary width, can be used, so that the material is almost immediately subjected to the action of the flats and all practical diliiculties as to the fitting of thc back plate or sheet are overcome. I use a laproller on which the lap to be fed rests and the level of the lap centre is about on the same level as the rear of the chain ot' flats and this allows me to make provision ilor supporting an extra lap in the iframe-work of the card and almost immediately below the lap supplying the material to be acted upon. I use two sets or crossrails one in liront of the eXtra lap and one below, or as found convenient, which with the elevated frame sides carrying the takerin secure greater lateral stability which is most desirable.

The attached drawings clearly illustrate the improvements:

Fig. 1 being a side elevation.

F ig. 2 is a sectional elevation, and,

Fig. 3 a plan.

According to the construction of card il-` lustrated and which embodies my improvements, I use a main cylinder a which is smaller in'diameter than usual, as for instance 1t may be 410". It might be considerably larger in diameter than 40 orit may even be less. The diameter of the ordinary or normal cylinder is about As in the Patent 1,567 ,5f-11, I still use a considerably reduced number of flats, say about 15, some 13 of which are in working position on the cylinder, the llats being marked b. Just below the level of the flats is the simple single cleaning orcombing mechanism clearly illustrated consisting of lap roller c (overwhich the lap Gis disposed), dish feed d, fluted roller e and taker-in f, the latter being for example about 9 in diameter;

but it may be greater or less. The shaft C" for the lap C is disposed in vertical slots C2 formed in brackets C3 carried by the machine frame. Mote knives g are used and a dirt grid g" with the taker-in f, and the takerin can be brought so close up to the flats as to allow of a very narrow back plate or sheet 7L being used, as is clearly illustrated, and such back plate or sheet may be even narrower than in the ordinary card. By reason of the position of the simple cleaning and combing mechanism a considerably augmented space c'- or dirt and impurities results, the full depth from the dirt grid of the taker-in to the floor being available, thus reducing the liability of the fly and impurities driven out by the taker-in f being drawn or sucked back by air currents between the grid bar spaces. A plain sheet lo encloses a section ofthe main cylinder and may extend to the floor. Dirt `grids Z are located below the main cylinder and a doller mi of some 22 or more or less may be used. The side frames below the simple single elevated cleaning and combing device are shaped to form brackets n2 and provided with slots n3 forming bearings to receive the lap rod n of an extra lap a which can thus be located below the lap in use.'

Two sets of crossrails are provided, the one set in front of the extra lap being marked 0, and the set below o.

The setting points may be two or three, as already mentioned, as against five in an ordinary card, this representing an important simplilication..

The improved construction of card in.-v

volves some changes in the driving arrangements, and these changes are clearly illustrated. I show the fluted roller e ot the elevated' cleaning and combing mechanism driven trom the side shaft j) by a short upright shaft p having bevel gear,- the upper bevel wheel driving the plate bevel c on the fluted roller c. For the doi/'ller drive, I am not able to drive direct by a strap onto the pulley on the dandy lever, as is usual, and so I drive by a vertical belt g from the pulley on the licker-in shaft to a pulley (l suitably carried. Another pulley q2 drives by a strap .Q3 the pulley g4 on the dandy lever, which pulley y* through the usual gear wheels actuates the doffer m. rllhe elevated licker-in is shown as driven by a crossed belt r from the main cylinder shaft.

rllhe complete card including coiler can and the full laps as illustrated occupies a longitudinal. space ol about 9-5 as against an over-all longitudinal space ot IOL-l in the case of an ordinary standard card.

The entire combination results in the obtainment of a considerably simpler but equally etlicient and more compact card, at once cheaper, moi-estable, and one which in use reduces practical di'lliculties such as setting, grinding, etc..to a minimum. These advantages are combined with a considerably augmented free space for dirt, ifly, droppings and impurities on the underside of the taker-in, that is, more space than now obtains on a standard carding engine.

I declare-that what I claim is l. In a revolving flat carding engine, the combination with a main cylinder and a chain of flats comparatively small in number disposed in cooperative relation to said main cylinder, of a single cleaning mechanism comprising` a taker-in roll supported tor rotation in contact with said cylinder above the horizontal center line thereand combing of, a horizontally extending plate disposed rearwardly in juxtaposition to said taker-in roll, a fluted roller mounted :tor rotation above said plate adjacent to said taker-in roll, a lap roller mounted for rotation adja-' cent to the rear edge ot said plate, a pair of slotted brackets disposed above said lap roller, a completely formed lap mounted :tor rotation-in said brackets in contact with said lap roller, a narrow back plate enclosing that portion of the main cylinder between the chain of flats and the taker-in roll, and driving mechanism tor said cleaning and combing mechanism.

2. In a revolving tlat carding engine, the combination with a main cylinder and a chain of Aflats comparatively small in number disposed in cooperative relation to said main cylinder, of a single cleaning and combing mechanism comprising` a taker-in roll supported for rotation in contact with said cylinder above the horizontal center line thereof, a horizontally extending plate disposed rearwardly in juxtaposition to said taker-in roller, a 'tinted roller mounted for rotation above said plate adjacent to said takerin roller, a lap roller mounted torrotation adjacent to the rear edge of said plate, a pair ot slotted brackets disposedabove said lap roller, a completely termed lap mounted for rotation in said brackets in contact with said lap roller, a narrow back plate enclosing that portion ot the main cylinder between the chain of 'Hats and the taker-in roll, a second pair of slotted brackets disposed at a lower level than said first pair for supporting an extra lap, and bevel gear driving mechanism from the side shaft ofthe card for driving the single cleaning and combingmechanism.

In testimony whereof I have signed my name to this specification.
