.To a/ZZ whom t may concern:

Beit known that we, THOMAS KNoWLEs, cotton-spinner, of No. 287 Blackburn Road, Bolton, in the county of Lancaster, and ROGER TATHAM, machine-maker, of Rochdale, in the said county, England, have invented certain new and useful Improvements Applicable to Oarding-Engines in which R evolving Flats are Employed, (for which We have obtained British Patent No. 2,912, dated February 27, 1888,) of which the following is a speciiication.

Our invention relates to those carding-engines in which revolving iiats are employed; and our invention consists in 'arrangements of apparatus for grinding the flats em ployedk in such'carding-engines.

For the purpose of our invention We cause the ,back7 of each end of the iiat about to be ground77 to travel along an inclined sur face and pass between the inclined surface and a fixed guide. Each of the inclined surfaces and iixed guides is mounted upon or connected in any suitable manner to one of the bends or side frames, or any other suitable part of the carding-engine, so as to be capable of being adjusted in position.

For convenience of description we shall hereinafter in vmany instances only refer to theapparatus situate at one side of the carding-engine, although the arrangements of apparatus in Which our invention consists and the apparatus used in conjunction with our invention are, in so far as may be necessary, applied alike to each side of the carding-engine. v

In the accompanying drawings, Figure l is a front view, and Fig. 2 a side view, showing so much of a carding-engine as is requisite to illustrate our invention. Figs. 3 and 4 are diagrams, on a larger scale, illustrative of certain details of the working ot' our invention.

The same letters of reference are applied to corresponding parts in all of the gures.

Secured to the bend of the carding-engine is a bracket a. To a projection a', formed upon the bracket a, is secured the curved bracket b, along the upper edge b of which the revolving iiats c travel when away from the main cylinder of the carding-engine.

i Mounted upon the bracket ct and secured thereto by the bolts d2 and nuts cl3 is a bracket e. The said bracket e is formed with a part e', the lower edge of which is formed with two surfaces e2 es, connected by an inclinedy surface e4.

Secured to the bracket a by the nut f is a studf, mounted upon which and free to be turned thereon is a lever g, one end g 0f which is formed with a flat or nearly-dat surface g2, extending from A to B, and inclined surfaces g8 g4. The other end of the lever g is provided with a weight g5, which tends to turn the end g of the lever g in the direction indicated by the arrow O. In place of the weight g5, a spring or other equivalent for such weight g5 may be employed.

Mounted upon the bracket a, and secured thereto by means of the bolt d and nut d', is a bracket h, which supports, so that it may be turned therein, one end of the axle j of the grinding-rollcrj.u The bracket h is provided with screws and nuts, by means of which the grinding-roller can be adjusted' into the required position; but as such screws and nuts are similar to those ordinarily in use for similar purposes we have omitted them from the drawings in order to avoid confusion. One end of each of the flats c while away from the main cylinder of the cardingengine passes between the end g of the lever g and thebracket e.

c c2 c3 are flats. The iiat c is about to be ground. The iat c2 is being ground by the grinding-roller j, and the dat c3 has been ground. The motion of each of the flats c in the direction indicated by the arrow D causes,

each of such Hats c to pass beneath the grinding-roller j. The' portion of each of the flats c which at times is against the surfaces I e2 e* e3 of the bracket e is that portion c4 of the fiat c which is supportedby the iiexible bend or other bend when the said flat c is at work.7 The movement of the flats c in the direction indicated by the arrow D will cause the portion c5 of each of such ilats c to travel along the inclined surface g4.and the surface g2 of the lever g. The weight gswill cause the end c6 of the flat c to be pressed against the surfaces e2 e3 of the bracket. The movement of the tiat c in the direction indicated by the arrow D will cause the edge 'c7 of the fiat c to pass along the surface e3 and the edge c8 to travel along the surface e2. While the edge c7 is traveling along the surface e3, and while the edge o8 is supported on the su rface e2, the Wire surface c9 of the Hat c will be operated upon bythe grinding-rollerj,which is caused to rotate in the manner in which grinding-rollers are ordinarily caused to rotate.

Fig. 3 is a detached view showing, upon a larger scale, the grinding-roller j and a section of a iat c being ground, the surfaces e2 e3 and inclined surface e4 being shown detached in order thatconfusion maybe avoided. The surface c3 is formed at such a height above the surface e2 that when the edge c7 of the flat c is traveling along the surface e3 and the edge es of the flat c is traveling along the surface e2 the fiat @will be tilted in the direction indicated by the arrowT E, so that the surface F F of the Hat c will be parallel to Vthe surface e2 and the surface e3, and that the card-wire surface c9 of the flat c willbe ground parallel to the surface F F of the ilat c, to which the card-wire a9 is attached. After the wire e9 of the flat c has been operated upon by the grinding-rollerj a continued movement of the flatc in the direction indicated by the arrow D will carry the flat c clear ot' the surfaces e2 e3 and the surface g2 upon the lever g. By causing the edges c7 @sof each flat c to travel along the surfaces e2 e3 while the flat c is being ground, We insure that the Wire of all the flats shall be ground uniformly in relation to the surfaces by which such flats are heeled when at Work.

The diagram Fig. 4 shows on a larger scale the advancing edge of a fiat as being about to commence to pass along the inclined surface e4, and indicates the mannerin which the part c10 of the card-clothing of a flat which may from any cause be too near the advancing edge of the tlat or may project too much from the foundation of such card-clothing will be ground so as to be brought into the condition requisite for proper working and so that it will not comeinto contactwith the card-surface of the main cylinder to agreater extent than the corresponding portion of each of the other flats. It will be seen from Fig.

4.- that before the edge c7 of the flat c commences to pass along the inclined surface e4 the angle 010 of the card-clothing upon the said flat c will, it' it is too near to the advancing edge of the iiat or projects too far from such fiat c, come into contact with the grinding-rollerj and receive a grinding and be ground down to the required extent. As soon as the edge c7 of the fiat ccommences to pass along the inclined surface e4 further contact between the card-surface of the dat c and the grinding-roller j will not take place until the edge c7 of the flat c arrives in contact With the surface c3. The angle c10 of the cardsurface of the dat c will thus be ground at an angle to the remainder of such card-surface.

The amount of cardingsurface to be presented to the main cylinder by the flats operated upon by the grinding-roller may be regulated by the extent to which the angle cl0 of the flat isl ground by the grinding-roller being varied. The extent to which the angle 010 of the flat is ground may be varied by the relative positions of the inclined surface c4 of the bracket e, and the point of contact between the angle c1@ of the VHat and the grinding-roller j being varied by the bracket e or the grinding-roller being moved in the direction indicated by the arrow G or in the direction opposite thereto into the required position.

If desired, special means for facilitating the movement of the grinding roller j or bracket c may be provided.

l-Iaving fully described our invention, what We claim, and desirev to secure by Letters Patent, is-

The hereinbefore-described arrangements of apparatus for grinding the flats employed in carding-engines in which revolving iiats are employed, which arrangements of apparatus consist in fixed parts provided with surfaces e2 and e3, formed parallel with each other and separated from each other by a diference of level such that a flat held against the surfaces e2 and e3 will have its card-Wire surface parallel to said surfaces e2 and e3 and in levers, such as g, by means of which the flats being ground may be successively held against the surfaces e2 e3, and arranged, employed, and operating in conjunction With a grinding-roller, substantially as and for the purposes hereinbefore described.
