LINT CLE ARING MEANS FOR DRAWING FRAMES AND THE LIKE Filed May 18, 1959 2 Sheets-Sheet 2 FIG 7 ""i llllliml v I INVENTOR M'l/iam E Lee BY a 1 ATTORNEYS United States Patent 3,141,200 LINT CLEARING MEANS FOR DRAWING FRAMES AND THE LIKE William Franklin Lee, P.0. Box 14, Glendale, S.C. Filed May 18, 1959, Ser. No. 813,918 12 Claims. (Cl. 19159) My invention relates to lint and dirt clearers or scavengers for textile machines and is applicable to all types of drawing frames, combers, coilers, carding machines and the like to prevent lint, dirt or foreign matter from accumulating in more or less sizeable bunches or masses and getting into the sliver or other work.

For instance in the operation of a coiler, loose fibres separate from the slivers being operated upon and are floated onto such as marginal surface areas of the flared trumpet entries, the trumpet-supporting beam or calender roll cover, and also onto the subjacent coiling mechanism covers through which the slivers are directed from the trumpets.

Such fibres or fly with dust from the air and sometimes oil from machine surfaces will, in the absence of preventive means, accumulate in various sized bunches on the areas mentioned to ultimately topple into the travelling slivers. Thus defective bunch-incorporating rovings and similarly defective yarns made from the latter result; and of course the yarn defects will also appear in subsequently produced cloth.

It is therefore the primary object of the present invention to overcome the difliculty noted by the provision of simple, inexpensive, and highly efficient means which can be readily applied by an ordinary mechanic to the textile machines mentioned without material structural alteration thereof.

More specifically, the invention contemplates an air circulating means for the purpose specified, which will prevent loose fibres, etc., from settling on the surfaces mentioned and which can, for instance, be readily applied to a coiling mechanism cover to be operated by the conventional coiler gear.

Invention also resides in certain novel features of construction, combination and arrangement of the various parts of the apparatus employed, and in modes of operation thereof, as will be readily understood and appreciated by those versed in the art upon reference to the accompanying drawings in connection with the detailed description thereof which follows.

In pursuance of patent statute requirements, the drawings illustrate certain now preferred examples of the invention. However, the illustration herein is to be taken as illustrative rather than limitative, since it is to be understood that my inventive concept is susceptible of other mechanical expressions within the spirit and scope of the subject matter claimed hereinafter.

In the drawings, wherein the same reference characters have been used to designate the same parts wherever they appear in the several views FIG. 1 is an elevational view, partly broken and partly in section, of my lint clearer attachment applied to the coiler mechanism cover of a conventional drawing frame which is fragmentarily illustrated in cross-section;

FIG. 2 is a section on the line 2-2 of FIG. 1 illustrat ing the drive connection with the coiler gear;

FIG. 3 is a front elevational view of the gear case portion of the device, partly broken and partly in section;

FIG. 5 is a view similar to FIG. 4 showing elements of another air circulating member;

FIG. 6 is a perspective showing of the application of a slightly modified form of the invention to a coiler cover; and

3,141,200 Patented July 21, 1964 FIG. 7 is a sectional view on the line 7-7 of FIG. 6.

Referring to the drawings by reference characters and turning to the form of invention shown in FIGS. 1-5, inclusive, the invention is illustrated in connection with a conventional high speed drawing frame.

The fleece 11 is indicated as being passed from between two of the front drawing rolls 10 to a trumpet 12 from which it emerges as a condensed sliver 11a to pass between calender rolls 14.

From the calender rolls 14 the sliver 11a passes through the central hole 15c of the coiler cover 15 to the usual coiling means which is not shown except for a fragment of the driven coiler gear 17. The coiling means delivers the sliver in coil form to the usual. coil-receiving can 16.

The funnel-like trumpet 12 is conventionally mounted with its flared mouth uppermost, as shown, in a hole in the calender roll covering beam or cover 13, as indicated in FIG. 1.

As indicated earlier herein, flying lint, dirt, etc., ac cumulates in bunches on the calender roll covering beam or member 13, the flared trumpet mouth and on the coiler cover 15 unless prevented from doing so, and such lint bunches topple or work into the sliver 11a to more or less spoil same. Thus, ordinarily an attendant is kept pretty busy wiping lint accumulations from the surfaces mentioned. This is not only time consuming and thus expensive, but if the attendant is not careful, lint bunches will get into the sliver 11a which means that the yarn ultimately made therefrom will be of inferior grade.

Coming now to my novel lint-clearing attachment, it will be seen that same comprises a gear case 18 composed of separably connected top and bottom plates 19, 20, respectively. These plates 19 and 20 have opposed inner surface recesses that define the shallow gear-receiving chamber 21.

Gear chamber 21 has a frontal opening, as indicated, so that the chamber housed spur gear 22 will have a portion projecting therethrough to mesh with coiler gear 17 when gear case 18 is assembled with the lower vertical flange portion 15a of coiler cover 15 opposite an opening 15b therein, as indicated in FIGS. 1 and 2.

As best indicated in FIG. 3, gear 22 is fast on the vertical shaft 23 which is journalled in, and extends above, the upper end of the upstanding sleeve form bearing 24 that rises from top plate 19 and is functionally integral therewith. This shaft 23 carries the vertically spaced air circulators, or impellers which are generally indicated at 31, 32 and will be referred to in detail hereinafter. The impeller 31 is located adjacent the top of the coiler cover 15 and the impeller 32 adjacent and above the plane of the top surface of the trumpet-carrying calender roll cover or beam 13.

In carrying out the invention according to FIGS. 1-5, the gear case-providing plates 19 and 20 are secured together by two end bolts 26 and a rear bolt 25. These bolts 26, 25 extend through opposed plate-provided apertures and receive nuts 26a, 25a, respectively.

Also to be noted is the fact that opposed end portions of plates 19 and 20 have bolt aperture-surrounding cutouts which cooperate to define a bearing seat 27 opening from the related gear case end. Each bearing seat 27 receives the inner bearing end 28a of an elongated attaching lug 28 which bearing end is pivoted on the adjacent plate-securing end bolt 26.

As will be understood, the attaching lugs 28 secure the gear case 18 to the lower vertical flange 15a of the coiler cover 15. Thus lugs 28 extend well beyond the adjacent gear case end as indicated in FIGS. 2 and 3, and are apertured as at 29 to receive bolts 30. These bolts 30 extend through the coiler cover flange 15a to engage interior nuts 30a, as shown.

Taking up now the details of the illustrated impellers 31 and Y32, and dealing first with the smaller lower impeller 31, it will be seen that same includes the relatively thick disk form base 33 having the upstanding concentric sleeve 34 which receives the gear driven shaft 23. Base 33 is vertically adjustable on shaft 23 and is secured in different adjusted positions by a set screw 35.

The preferably leather-like or other flexible blades 38 are received in opposite outwardly opening base-provided slots 36 and are secured therein by screws or pins 39. These pins 39 are received in base-provided slot crossing holes 37 and, as shown, each blade 38 has a hole 38a through which the related pin 39 extends.

In the case of the upper or larger impeller 32, its mount is the elongated and preferably cylindrical member 40 which has opening from its lower end the elongated concentric shaft (23) receiving bore 41. Bore 41, as shown, terminates short of the inner end of the blade-receiving cross slot 43 which opens from the upper end of mount 40.

Exteriorly open and tapped transverse holes in mount 40 open into bore 41 and cross slot 43, respectively, to receive the respective set screws 42 and 46. Set screw 42, of course, secures mount 40 in various vertically adjusted positions on shaft 23; and set screw 46 retains the impeller blade 44 and its mount 40 assembled.

Impeller blade 44 is preferably of leather or other flexible material having a material degree of stiffness, and it provides the enlarged end wings 45 as shown.

Referring now to the invention as expressed in FIGS. 6 and 7, the gear case 5!) differs in certain respects from that indicated at 18 in FIGS. 1 and 2 in that it provides thick and elongated bottom plate 51 and a smaller top plate 54.

Also the bottom plate 51 provides the open sided chamber 52 for gear 53 that is fast on the shaft which latter projects up through top plate hole 54a and the upstanding and functionally integral top plate carried bearing 56.

Gear 53 and shaft 55, of course, correspond to elements 22 and 23, respectively, in FIGS. 1 and 2; and shaft 55 carries the impellers 31 and 32 as in FIGS. 1 and 2, the description of which is by reference made a part of this description of the FIG. 6 and 7 modification.

Bolt and nut assemblies 57 secure the gear casing-providing plates 51, 54 together as indicated, but do not mount attaching lugs such as 28, 28a in FIGS. 1 and 2.

The coiler cover 58 of FIG. 6 is the same as shown at 15 in FIG. 1 except that its lower vertical flange portion 58a (which has cut out 581)) is provided with the horizontal outwardly projecting posts 59 adjacent opposite ends of flange cutout 5812. As indicated in FIG. 6, these coiler cover flange-carried posts 59 have the transversely extending holes 59a adjacent their outer ends to receive the shanks of screws 61, having wing nuts 61a. The head-adjacent portions of the screws 61 project transversely through holes in the fixedly carried upstanding posts 60 of the lower gear casing plate 51. Thus posts 59, 60 and wing nut-carried screws 61 function to hold gear case 50 and coiler cover 58 assembled with the gear 53 in mesh with the coiler gear 17 as in FIGS. 1 and 2.

For purposes of this specification the coiler cover 15 (of FIG. 1) and 58 of FIGS. 7 and 8 are to be considered as portions provided by the fragmentarily illustrated drawing frame of the art machine (see FIG. 1 particularly).

The operation of both forms of the invention will be evident. The coiler gear 17 acting through gear 22 (FIG. 1) or gear 53 of FIG. 7 drives the impeller-carrying shaft and the impellers 31, 32 set up a circulation of air in the region of coiler cover 15 (or 58) and trumpet 12. This prevents lint accumulations on or near said surfaces and the use of flexible impeller blades 38, 45 is preferable to avoid possible injury to attendants.
