WARPER LINTTV CLEANER.

Application filed November This invention relates to a pneumatic mechanism for maintaining a warper free from lint and fly at those places where a collection of lint and fly is injurious to the operation of'the warper. 1 T

The invention has for its main object to provide means for blowing a draft of air along the dents of the warper combs toward the free ends so as to maintain the combsfree from fly and lint.

The invention has for its further object to provide a warper lint cleaning mechanism of the pneumatic type which will be simple. practical and eflicient in its operation and prevent the collection of fly and lint particularly on the warper com s.

These and other objects and features of the invention will appear more fully from the accompanying description and drawings and will be pointed out in the claims.

As the invention only has to do with the lint cleaning feature and as the general construction and operation of warper-s are well known and familiar to those skilled in the art, and as the invention may be applied to various types of warpers, it is'suflicient here to illustrate only those parts of a single type of warper with which the invention is particularly concerned.

In the drawings: 1

Fig. 1 is a side elevation of'a warper partially in cross section and with many of the parts omitted, and having embodied therein a preferred form of the invention. A

combs.

Fig. 3 is a detail in side elevation, broken away, of a portion of a warper similar to that shown in Fig. 1, but showing a slightly different form of combs with the blowers arranged to blow the air along the dents and toward the freeends thereof.

In a warper, the warps are taken usually from a creel and wound on a warp beam. Such warpers are provided with combs for separating and guiding the warps, with drop wires for stopping the warper if a warp breaks and with other instrumentalities upon which moreor less fly and lint is likely to collect, and this is particularly true of the warper combs which are usually located at the rear and front of the warper.

The warper illustrated in Figs. 1 and 2 1, 928. Serial No. 316,423.

comprises side frames 1 and is shown as V supporting suitable guide or lease rods 2, a rear combr3, a bank of drop wires'4. a

front comb 5 and a suitable front guide roll 6. The warps 7 are laid from the creel through and over these various instrumentalities and wound up on the warp beam 8 mounted at the front of the warper.

The combs 3 and 5 are made up of a transverse row of dents 9 herein shown as round wires having vertical shanks with the-p01 tions 10 inclined upwardly and away from V a vertical plane extending laterally of the warper. J In both combs the inclined portions 10 of the dents are shown as extendrection oftheir inclination, thus maintaining them free and clear of fly and lint and blowing any fly and lint that tends to collect-thereon well forwardover the front of the warper. r I

The nozzle at the front of the warper is shown as a box-like structure 11 mounted on the frame and extending transversely of the warper in the rear of the front comb and having its mouth 12 open at the base of the dents 9 and inclined in the same direc- Another nozzle 13 of similar structure, shape and position is shown at the rear of the rear comb.

' dents toward their free ends and in the di- A main conduit shown as a large pipe 14 is mounted onrthe frame preferably about midway between the nozzles 11 and 13 and extends parallel therewith. Branch conduits 15 connect the main conduit and the nozzles ateach side and are preferably so. arranged that they open into the nozzles at regular intervals transversely or laterally of the warper.

Air under pressure is supplied to the main conduit and thence to the nozzles and may be obtained from any suitable source. As illustrated, ablower l6 is mounted at the rear of the warper and connected by a pipe 17 to the main conduit, but any suitable means mayb provided for thus supplying the required air under pressure.

The construction. illustrated. in Fig. 3. in.- volves the. same principles,. but; a slightly different form of comb. Herein the combs 18 and 19 at the front and the back: of thewar'per comprise straight dents 20, but the combs as a whole areshownsetiat an angle" so as topoint upwardly and forwardly. In this case the nozzles 21 have their mouths 22 extending close to andparallel with the dents so that the draft of air issuing therefrom is projected along the dents to ward their free ends. The relation of the nozzle to the combs is a most important feature and it may not even be necessary to incline the dents because with the: air draft projected along the dentstowardtheir' free ends, the combs will be: cleared of fly and lint and the draft caused by the moving warps, especially with the high. speed 4 It will thus be seen'that a strongvair is blown from each nozzle along the warperdentstoward the free ends thereof in 7 an upwardly and preferably in. atransversely inclined direction. This-renders it imposand as it has no moving. parts, it does .not

interfere in any way with the operation of t'hewarper. The main and..branchconduits may l e-located at any suitable position since their only function-is to transmit theaair under pressure to-the nozzles.

blast of sible for any fly or lint to collect on the warper combs and throws the lint and fly clear of thewarpen It is-found in practice thatthe agitation of the-other. elements and:

the movement of the air-resulting from the draft-thus produced maintains the-other ele-,

and lint. 7
