T 0 all '107mm 'it may concern Be it known that We, FRITZ Vs'rnn and MAX JUNGBAUER, both of Augsburg, Germany, have invented certain new and useful improvements in Carding-Engines, of which the following is a speciication.

This invention relates to apparat-us for cleaning the card clothing of earding engines by suction and its object is to provide improved means whereby the card clothing may be cleaned or stripped by suction alone Without the assistance of rotating brushes or air under pressure as has hitherto been proposed.

lt is well known that in the process of cai-ding textile ibers the short angular Wires of the carding engine cylinders become clogged with fibers or impurities which must be removed periodically. This removal of all impurities that become embedded in the card teeth is called stripping Carding engines usually. employ a Amain carding cylinder and a doifer; it is the main cylinder that actually performs the carding operation, While the doii'er merely removes the carded fibers from the points of the teeth ofthe main cylinder. |This diiference of func-- tion causes the matter embedded in the teeth of 'the cylinder and dolier to diifer very considerably; z'. e., the material that clogs the teeth of the main cylinder consists of seeds, leaf and short-staple cotton, and these materials become'very firmly matted and embedded in the wires of the card clothing and are therefore very diliicult to remove satisfactorily. Thev material that clogs the teeth of the doiier isof a very diiierent nature-particularly all of the heavier irnpurities (leaf, seeds, etc.,) having been rcmoved by the main cylinder-a-nd consists almost entirely of short-staple cotton and dust, which is not very firmly embedded and therefore is not ditticult to remove, this being due, as stated above, to the work of the dotier, viz., the removing of the already carded fibers from the nia-in cylinder.

Prior to the present invention rotating brushes were used to remove the embedded materials from the teeth of the card cylinder. In thisoperation the -ibrous portions of the embedded material clung to the wire teeth o f the brush, but the' greater bulk of the heavier portions of the embedded materials and the Whole of the dust were thrown into the atmosphere, which Was thus polluted. Many attempts have heretofore lbeen made to utilize suction for collecting the materials (dust, leaf, and seeds) thrown linto the atmosphere by rotary brushes; in Vsome eases suction nozzles have been arranged near the brush, but such constructions have had no commercial success; in .other cases 'the brush hasbeen inclosed in ia. -canopy or hood to catch or retain the winst, etc., which Was then carried away through suction pipes connected to the interior of the hood, and such arrangements, although removing the dust, have not obviated the disadvantages of the rotary stripping brush. vantages are (l.) It is impossible to clean the carding surface of the cylinder completely With a brush. The carding surface consists of bent wlres usually set in a rubber-faced. fabric and if the rotary brush were set deep enough to reach the fabric in Which the teeth are manently. (2.) The Wires or teeth of the card clothing are bent at an obtuse angle, so the rotary brush besides blunting the points is liable to injure the Wire teeth themselves they are mounted. v

(3.) lt is impossible to use a rotating brush While the cylinders are rotating at full speed. The carding engine must be stopped, and the cylinder subsequently rotated slowly While the stripping brush is being applied. From this it will be gathered that it is much tant commercially to clean the main cylinder than it is to clean a dolfer; a. doifer could be easily stripped in several Ways, but the cleaning of the main cylinder was for years a diliicult matter.

One of the objects of the present invention is to provide means whereby the carding cylinder may be cleaned by suction While the same is running at full speed.

A further object is to provide means for and for shifting the same so as to traverse the entire cylinder surface.

The invention Will be hereinafter fully set forth and particularly pointed out in the claims'.

The chief of these disad and to loosen them in the fabric in whichmore difficult and also much more imporlined the said fabric Would be injured perproviding a suction opening 'of small volume In' the faccomp nying drawings'Figure 1 is a diagrammati jside elevation of a carding engine showing one vway in which the improvements may be applied g' Fig. 2 is aV front elevation, 'partlyin section, of the traverseV mechanism, the nozzle being showny y in cross section; and Fig. 3 is a side eleval ran ed parallel with and adjacent to the nozzle car ing surface b of the engine.

Each nozzle N is mounted upon a carriage t which consists of a collar provided with a guide 1in adapted to engage with adoublethreade screw s; the said carria e slides upon a fixed tube u which incloses t e screw s and which is formed with a .longitudinal slot through which the guide pin projects in order to engage with the threads of the screw s, rotation of the carriage u on the tube u bein thereby prevented. uitable ing the carriage t and nozzle N to reciprocate in front of the card clothing b.

The operation is as follows: While the cardin engine cylinder is in motion the il? is traversed across the carding surface b, the pump having been set in operation. The result is that, owing to the hi h pressure suction set u and maintained gy the ump, and the re atively small volume of t e suction nozzle theiibers, neps, dust, and other foreign matter embedded in the card clothing b are drawn through the nozzle N, effectively cleaning the card clothing b as indicated in Fig. 2, whue the fibers, i

naps, dust and other foreign matter are collected and prevented from' getting into the pump by the filtering action of the col-` lecting box. v v f lof a screw extendin along gcardmg surface,l a screw ,rotatable` in the z sleeve, a nozzle of small volume slidable on the sleeve and having va pin .through the slot and engagmg t e screw, yand means for creating a suction in the nozzle.

1. In a carding machine, the combination entirel across and parallel with the car ing sur ace,^a suction nozzle of.- small volume mounted on the screw, means for rotating thescrew to move thel nozzle longitudinally therein, and means for creating a suction'm said nozzle. l

'2. In a carding machine, the combination L with the carding surface thereof, of a suction nozzle of small volume, means for moving the nozzle entirely across said'surface in a plane parallel therewith, and means for creating a suction in said nozzle.

3. In a carding machine, thev combination with the cardin surface, of a xed sleeve extending entire y across said surface and provided with a longitudinal slotl extending the whole working breadth of the rojecting 4. In a carding engine the combination with the cardi-n surface thereof,'of suction means provide with asuction opening of jsmall volume opposite `said surface, and' f means for causing sald suction opening to traverse said cardmglsurface irrespective of l the speed of movement of the latter.

5. rEhe combination, with the Vmain cylinj derpof a Cardin machine of an air nozzle of 1small 'volume irected against the idle side of said cylinder, means to produce a suction 'current through' said nozzle, and means to traverse said nozzle progressively to all parts of said cylinder as the latter rotates.
