F 4 BY g lwhgw ATTORNEYS APPARATUS FOR CLEANING TEXTILE ROLLS Iohn McQollough, Jr., Gaifney, S. C., assignor to Deering Milliken Research Corporation, Pendleton, S. C., a corporation of Delaware Application June 16, 1952, Serial No. 293,760 2 Claims. (CI. 15-21) This invention relates to an apparatus for cleaning textile rolls and more specially to a machine for cleaning clearer rolls of the type covered with felt or other relatively soft material and which are used on drawing frames, spinning frames and the like for removing accumulations of lint and foreign matter from the usual top rolls thereof.

There are many different types of clearer rolls, but most clearer rolls generally comprise an elongated shaft having reduced journaled portions on opposite ends thereof and which shafts are covered with felt or similar padding. In some instances, the padding extends the entire length of the shaft and, in other instances, the padding is arranged as bosses spaced longitudinally on the shaft. The clearer roll usually rests in engagement with the upper surfaces of top rolls of a spinning frame or the like and any accumulations of lint or other foreign matter picked up by the top rolls will, in turn, adhere to the clearer rolls and will thus be wrapped around the clearer rolls in various degrees of depth, hardness, compactness and matted conditions, with the result that the clearer rolls have to be removed from the machine and cleaned periodically.

it is the primary object of this invention to provide a simple and efiicient machine for cleaning such clearer rolls automatically.

It is another object of this invention to provide a cleaning machine for clearer rolls and the like comprising a rotary brush, the bristles of which are preferably made from relatively fine wire, such as burnishing wire, with a pair of guide members, such as rods or shafts, spaced slightly above the rotary brush and parallel to the axis thereof. A pair of plates or blocks slotted at their upper edges extend between and are slidably mounted on the guide members to facilitate relative adjustment thereof, the slots in the plates being adapted to receive the reduced ends of a clearer roll and the longitudinally adjustment of the blocks facilitating the accommodation of clearer rolls or the like of varying lengths. Suitable means are provided to drive the rotary Some of the objects of the invention having been stated, other objects will appear as the description pro ceeds, when taken in connection with the accompanying drawings, in which Figure 1 is a top plan view of the improved roll cleaning machine with portions thereof broken away to illustrate the manner in which the clearer roll is sup ported during the cleaning operation.

Referring more specifically to the drawings, the numeral 10 broadly designates a frame or enclosure of the machine. The casing or housing for the machine may be of any desired construction and, in this instance, comprises a base formed from angle bars 11, 12, 13 and 14 to which a bottom wall or panel 15 is suitably secured. Each of the longitudinally extending angle bars 13 and 14 has the lower ends of upright angle bars 16, 17, 18 and 19 suitably secured thereto, each of the respective pairs of angle bars 16, 17 and 18, 19 being spanned by respective upper frame members or angle bars 22 and 23 suitably secured thereto.

The upper ends of the front vertical frame members or angle bars 16 arespanned by an angle bar or frame member 24 and the upper ends of the rear angle bars 19 are spanned by an angle bar or. frame member 25 suitably secured thereto. The upper ends of the angle bars 18 are also spanned by a transverse frame member or angle bar 26. A top wall 28 having a transverse opening 31 therein is suitably secured to and spans the distance between the respective pairs of frame members 22 and 23. Suitable side walls are indicated at 29 and 30.

Each of the front upright angle bars or frame members 16 has a vertically grooved guide 32 fixed thereto and each of the rear vertical angle bars or frame members 19 has a vertically grooved guide 33 suitably secured thereto for slidably receiving respective front and rear panel doors 35 and 36. The doors 35 and 36 are provided with respective pairs of horizontally spaced handles 37 and 33 fixed to the outer surfaces thereof for raising and lowering the panel doors 35 and 36 as desired for access to the interior of the housing or casing 10. It will be observed in Figures 1 and 3 that suitable locking means such as a pair of thumb screws 40 slidably penetrate each of the doors 35 and 36 and are threadably embedded in the corresponding transverse frame members 24 and 25 for securing the doors 35 and 36 to the frame of the machine to permit the handles 37 and 33 to be utilized for transporting the machine from one place to another. Of course, when the machine has been transported to a desired location, the locking means 40 may be released to permit the doors 35 and 36 to be raised and lowered.

Now, referring to Figures 3 and 4, there is shown a rotary brush, broadly designated at 42, which is spaced below the opening 31 in the top wall of the housing 10. This rotary brush 42 may be constructed in various ways and preferably comprises a wooden roller 43 having its periphery covered with a spirally arranged strip of base fabric or other flexible material 41 having extending therefrom closely spaced relatively fine bristles 44 which are preferably made from burnishing wire and extend radially from the periphery of the wooden roller 43. The strip of material having the burnishing wire bristles extending therefrom is applied to the roller 43 in much the same manner as card clothing is applied to card cylinders. The wooden roller 43 is fixed on a shaft 45 which extends beyond opposite ends of the wooden roller 43 and is rotatably mounted in bearing blocks 46 suitably secured to the side walls 29 and 30 (Figures 1 and 2).

The rotary brush 42 is driven continuously by suitable means such as an electric motor 47 fixed to the upper wall panel 28 and coupled to the rotary brush 42 by V- pulleys 50 and 51 and a V-belt 52. The upper wall panel 28 is provided with an elongated opening through which the belt 52' extends and which opening is closed by a suitable shield 53 which extends over the upper portion of the V-belt 52 and the V-pulley and is suitably secured to the top wall 28 of the housing 10. Suitable wires 54 and 54a extend to a source of electrical energy, not shown.

Each of the side panels or side walls 29 and 30 have a pair of spaced vertically extending slots 55 and 56 in that portion of the upper edge thereof which bridges the opening 31 in the top wall 28 and which slots are slidably penetrated by the ends of horizontally disposed guide members 57 and 53 which are shown in the form of rods or shafts. The ends of each of the shafts 57 and 58 are provided with reduced threaded portions 61 which slidably penetrate an adjustment plate or block 62 and each reduced portion 61 has a nut 63 on the outer end thereof for securing the ends of the guide members 57 and 58 to the adjustment blocks or plates 62. The adjustment plates or blocks 62 are provided with a pair of vertically extending adjustment slots 64 therein which are penetrated by screws 65 for securing the corresponding adjustment blocks or plates 62 to the corresponding side walls 29 and 30 of the housing 10.

The guide members 57 and 58 are spanned by a pair of longitudinally spaced roll support members or plates 66 and 67 which are slidably mounted on the guide members 57 and 58 and are adjustably secured thereto by any suitable means such as set screws 70 (Figure 4). Each of the roll supports 66 and 67 is provided with a transverse vertical groove 71 positioned substantially midway in the upper edge thereof for reception of the journal portions 72 at opposite ends of a clearer roll or the like 73 having a felt covering or felt covered bosses 74 thereon. The guide members 57 and 58 are closely spaced above the rotary brush 42 and may be adjusted relative to the rotary brush 42 by means of the adjustment blocks 62 so that the bottoms of the grooves 71 in the roll support 66 and 67 may support the roll 73 in a predetermined position relative to the rotary brush 42.

Thus, the roll 73 may be accurately positioned so that the bristles 44 of the rotary brush 42 barely touch the felt or other covering material during rotation thereof in order to remove accumulations of lint and other matter from the covering material 74 on the roll 73. This insures that the felt or other covering material or padding will not be ripped, out or damaged in any way by the bristles 44.

It is evident that rolls of various diameters and lengths may be cleaned with the present apparatus by vertically adjusting the guide members 57 and 58 relative to the rotary brush 42 in accordance with the diameter of a particular roll 73 to be cleaned and, also, by adjusting the supports 66 and 67 relative to each other along the guide members 57 and 58 to agree with the length of the roll 73 to be cleaned.

In order that the supports 66 and 67 may clear the bristles 44 of the rotary brush 42, the lower surface of each of the supports 66 and 67 is cut away, as at 76 as is clearly shown in Figures 3 and 4, this lower surface 76 of each of the roll supports 66 and 67 preferably be ing curved to conform substantially to the curvature of age path of travel of the bristles 44 on the rotary brush Retarding weight means in the form of a hinged cover or drag bar 80 is provided to retard rotation of the roll 73 as the cover thereon is being cleaned by the rotary brush 42. The drag bar 80 extends at least the full length of the rotary brush 42 and normally rests in frictional engagement with the clearer roll being cleaned and substantially closes the opening 31 in the top wall 28. This drag bar 80 should preferably be of a relatively light material, such as wood and the like to merely retard rotation of the clearer roll 73 while permitting roll 73 to be rotated by the brushing action of the bristles 44 of the rotary brush. The drag bar 80 may be supported '4 in any desired manner and, in the present instance, a frame member 81 in the form of an angle bar is suitably secured to the front portion thereof and a pair of strap members 82 are secured to the member 81 and extend rearwardly and are hingedly connected, as at 83, to the upper wall 28 of the housing or casing 10 adjacent the rear edge thereof. A suitable handle 84 is preferably provided on the cover or drag bar for raising the same to substantially the broken line position shown in Figure 3 to facilitate removal and replacement of clearer rolls. in actual practice, it has been found that when the bristles 44 of the rotary brush 42 are formed from burnishing wire, the rotary brush is virtually self-cleaning, the lint and other foreign matter being removed therefrom due to the action of centrifugal force only.

However, in the event that the rotary brush 42 becomes heavily embedded with lint and the like, the centrifugal force may be insufiicient to thoroughly clean the rotary brush 42. I have, therefore, provided a plate 86 which extends longitudinally beneath the rotary brush 42 and is provided with a plurality of closely spaced teeth 87 thereon which project into the path of travel of the bristles 44 of the rotary brush 42. This plate 86 may be supported in any desired manner and in the present instance I have provided a pair of brackets 90 whose upper ends are suitably secured to the plate 86 and whose lower ends are suitably secured to a base plate 91 which is, in turn, suitably secured to the bottom plate 15 of the housing 10.

It is thus seen that I have provided a unique apparatus for cleaning individual rolls of varying lengths and diameters and wherein a rotary brush is provided in combination with means to accurately position the roll to be cleaned relative to the bristles of the rotary brush to thereby entirely remove any accumulations of lint or other foreign matter from the felt covering or padding on the rolls without injury to the felt covering or other padding.

In the preferred simplified construction, the cleaning apparatus is light in weight and is readily portable from place to place by means of the handles 37 and 38. This permits efficient utilization of the apparatus adjacent the machines having the clearer rolls thereon.

In the drawings and specification there has been set forth a preferred embodiment of the invention and, although specific terms are employed, they are used in a generic and descriptive sense only and not for purposes of limitation, the scope of the invention being defined in the claims.
