CARD cLotueTINGr` FOR CARDING ENGINES.

Application led July 18, 1921, Serial No. 485,734. Renewed .Tune 17, 1925.

To all whom t may concern:

Be it known that I, Pnosrnn OGER, a subject ot the King or' Belgium, residing at Roubaix, in thejRepublic of F rance, have invented new land useful Improvements in Card r Clothing lforv Carding Engines, oi' which the lfollowing is a specilication.

This invention relates to the card clothing employed for the`4 rollers of carding engines, generally designated by the name 0i' llyers andthe :function of which is, as is welllrnown, to strip the cylinderl of the carding engine.`

In card 'clothing' hitherto employed for the flyers of carding engines7 the setting of the clothings is e'ii'ected parallel with the axis of the flyer, the hooks of the clothing being directed in planes at right angles to the axis of the flyer. These clothings, by working between the clothingsot the cylinder, remove' more or` less' completely the wasteand materials which accumulate between the clothings of thel cylinder, but are unable vrto remove the waste and materials which lodgebetweenthe teeth oi' the clothings of the cylinder, situated in the same plane. VIt therefore becomes necessary at certain times to stop the working of the machine in order to carry out a complete stripping of the cylinder. U

The present invention has forits principal object `to obviate this disadvantage, that is-to say to obtain a more complete stripping of the clothings of the cylinder by permitting the clothings of the'flyer to exercise their action evenbetween the teeth of the clothings of the cylinder situated in parallel planes at right angles to the axis of the cylinder. e

With this object in view my invention essentially consists ina special arrangement of the hooks of the clothing of the flyer whereby the ends of the hooks are caused to act between the teeth placed in the same plane on the cylinder, as will be hereinafter pointed out in the appended claims. p f* Referring to the annexeddrawing:

Fig. l shows diagrammatically the arrangement and mode of the setting employed hitherto for the clothing of the iiyers and the cooperation of these clothings with those of the cylinder ot the carding engine.

Fig. 1a is a front view of a part of a clothing of the usual construction.

Fig. l? gives a'section taken on line A-B and Fig. lc a section on line C-D in Fig. la.

Fig. 2 and Fig. 3 are longitudinal sections oit a flyer showing diagrammatically the arrangement of the hooks of the clothings according to the invention. Fig. 2a is a iront .view of va part of a clotl ing provided with the setting shown diagrammatically in Fig. 2.

Fig. 2b is asection taken on line E-F and Fig. 2c a section taken on line G-H in Fig. 2a. Y l

Figs. 4. and 5 are front elevations of flyers showing the clothing on the surface of said iiyers.

Figs. 6 and 7 show diagrammatically another mode ofthe setting which can be used inthe arrangement shown in Figs. 2 to 5. Fig. 6"L is a front view of a part of a cloth- Jling provided with. the setting shown in Fig. b'is a section taken online I-J and Fig. 6c a'section taken on Aline K-L in Fig. 6a.

In the ordinary clothing for flyers of carding 'engines, the settingis effected, as is well known parallel with the axis of the flyer, or, in'other words a plurality of wires (Fig. l) provided with two'branches b at right angles with a central part @are xed on or passed through ay supporting material 79 (Figs. la lb le), such as leather for nstance, in such a mannerthat the branches project from the supporting .material gi which is then placed on the surface of the yer with the central part a of the wires parallel with the axis of the flyer.

The projecting branches form then hooks b1 which are situated in planes parallel with each other and at right angles to the axis. -The result isk that the points or teeth of the hooks b act solely between the parallel rows c formed by the hooks oiPA the clothing of the cylinder of the carding engine as shown diagrammatically in Fig. l (in which the points of the hooks of the clothing of the carding engine have been shown) but'cannot 'exercise their actionin the spaces d comprised between the successive points or teeth ci' the same row of the clothing of the cylinder.

This disadvantage is avoided, according to my invention by giving to the hooks bl a lateral inclination that is to say towards the right or towards the left, with respect to the axis of the iiyer as is shown in Figures 2 and 3 which represent sections of the flyer e mounted on its shaft f. Under these conditions the inclined hooks b1 penetrate into the spaces d (Figl.) of the clothing of the cylinder of the carding engine and are able to remove the waste and the materials which accumulate during the working of the carding engine.

The two inclinations7 to the right and to the left may naturally be combined on the same flyer and the clotliings may be advantageously arranged in the form of chevrons g and' h adjacent to each other, as shown in Fifg. l or again in the form of chevrons leaving between them uncovered intervals i on the surface of the flyer as shown in Fig. 5.

Under these conditions, the lateral action, due to tlie inclination becomes reinforced, the stripped material having a tendency to collect at the ends of the flyer. ln practice, this action may be combined with ato and fro movement of the flyer, from left to right and from right to left.

The lateral inclination of the hooks b1 can be obtained by aid of the usual sett-ing as it is shown in Figs. 2 2b and 2C. In this case the central part a of the wire (Fig. 2a) extends longitudinally in contact with the back of the supporting material p, parallel to the axis of the flyer upon which the clothing is placed, and the branches are passed through said supporting` material as .it is the case in Figs. lFL 1*"13 but the hooks 1 ininstead of being formed in the same planes as the part b2 of the branches Z) which passes through the supportingl material y) and at right angles to the axis of the flyer are deflected laterally at b3 as it will appear from a comparison of Figs. 2a 2b and 2C in such a manner that the points or teeth of the hooks end in planes at right angles to the axis of the flyer but parallel to the planes containing the part b2 of the branches passing threugh the supporting material.

rlhe same result however can also be obtained with the form of hooked wires shown in Figs. lfL lb le, that is with the usual form of hooked wires by adopting the setting shown diagrammatically in Figs. 6 and 7 which is effected at a suitable angle relatively to the axis of the flyer so that the teeth of the clothings hooked in the ordinary way are no longer situated in planes at right angles to the axis of the flyer but rather in oblique planes parallel with each other. This mode of setting is further illustrated in F igs. 6, 6l and 6C. As it will appear from a comparison of the said figures, the central part a of the wire is again placed on the back of the supporting material p but the. branches b are passed through said supporting material on two parallel lines traced at different levels on the supporting material in such a. manner that the hooks b1 are directed laterally although being formed at right angles to the central part a just like in the case shown in Figs. la 1b l".

lit should be noted that the arrangement described might be also carried out by means of two cylinders covered with a strip of clothing forming very pronounced spirals, one covering running towards the left and the other towards the right, and further that the arrangement may also be combined with the ordinary system of setting, the same cylinder or iyer being provided on its periphery with parts of clothing set in the ordinary way (Figs. la lb, le) and parts set towards the left and right (Figs. 2 and 3) according to the effect desired to be obtained.

Vilhat l claim is:

l. Card clothing for fancy rollers of carding engines in which the teeth of the rows running perpendicularly to the lateral edges of the fabric are inclined toward one ofthe said edges, whereby the said teeth are adapted to act between the teethY of the clothing of the main cylinder which are situated in parallel planes at right angles to the axis of the main cylinder of the cardingengine.

2. ln combination with a fancy roller of a carding engine, a card clothing covering the said fancy roller, the said clothing comprising rows of teeth, the points of the said teeth being inclined laterally in the longitudinal diametral planes of the fancy roller containing the said .rows of teeth, whereby the said teeth are adapted to act between the teeth of the clothing of the main cylinder which are situated in planes parallel to each other but at right angles to the axis of the main cylinder of the carding engine.`

ln testimony whereof l have signed my name to this specification in the presence of two subscribing witnesses.
