LINT REMOVER Filed Nov. 12, 1963 2 Sheets-Sheet 2 United States Patent 3,225,373 LINT REMOVER Frederick N. Kishany, Port Huron, Mich, assignor to Diorama, ind, Cincinnati, Ohio, a corporation of Ohio Filed Nov. 12, 1963, Ser. No. 322,686 9 Claims. (Cl. 15104) This invention relates generally to lint removing devices, and refers more particularly to a roller type device for removing lint from clothing and similar fabrics.

One of the essential objects of this invention is to provide a roller type lint removing device in which a sleeve bearing a tacky material can be removed and replaced readily and without requiring disassembly of the device.

Another object is to provide a lint removing device having a rotatable cylindrical core which is compressible at one end to enable the sleeve bearing the tacky material to be readily slipped on and off the core by an endwise movement.

Another object is to provide a lint removing device having a tubular cylindrical core of flexible material which is open at one end and has one or more slots extending longitudinally from the open end, to enable the core to be radially reduced at the open end and the sleeve to be slipped on and off the core by an endwise movement.

Another object is to provide a lint removing device wherein the core has a radially outwardly extending flange at the open end normally blocking endwise removal of the sleeve, the core being suficiently compressible to enable the sleeve to clear the flange when the sleeve is slipped on and off.

Another object is to provide an elongated core having a pair of diametrically opposed members extending parallel to the axis of rotation of the core in supporting relation to the sleeve, the members being sufliciently flexible to permit the sleeve to be slipped on and off by an endwise movement.

Another object is to provide a lint removing device having means for severing lengths of tacky material wound convolutely upon the sleeve.

Other objects and features of the invention will become apparent as the description proceeds, especially when taken in conjunction with the accompanying drawing, wherein:

FIGURE 9 is an enlarged view taken on the line 9-9 of FIGURE 7.

Referring now more particularly to the drawing, and especially to FIGURES 1-5, the lint removing device 3,225,373 Patented Dec. 28, 1965 ice there illustrated comprises a handle 10, a core 12 rotatably mounted on the handle, and a sleeve 14 fitted on the core. The sleeve 14 may include a tube 16 of cardboard or like material having a long strip 18 of adhesive convolutely wound thereon. The strip or tape 18 will be tacky on its radially outer surface to pick up lint on clothing or similar fabrics, and the tackiness will serve to stick the overlying turns of the spiral tape to one another.

The core is essentially an elongated hollow tube or cylinder having a cylindrical wall 20 and being closed at the inner end by a transverse end wall 22. The outer end of the cylinder is open. The cylindrical wall 20 of the core is slotted at diametrically opposite sides. The slots are designated 24 and extend lengthwise of the cylinder from the open outer end slightly more than halfway toward the closed end thereof. The remaining elongated portions of the cylindrical wall 2% between the slots 24 are diametrically opposed to one another. These portions or members are designated 26 and 23.

The core 12 is made of a flexible resilient material, and in the present instance is made from a suitable plastic having these characteristics. Hence the

elongated members

26 and 28 can be flexed toward and away from each other. Normally, that is in their free state, these

members

26 and 28 will extend in a lengthwise direction parallel to the center line of the cylinder. Their outer surfaces will be of the same cylindrical shape as the unslotted portion of the Wall 20. However, these members are not attached at their free or outer ends so that they may be flexed radially inward with only a slight application of pressure.

The inner end of the core 12 a continuous radially outwardly extending annular flange 3%) which is in effect an extension of the end wall 22. This flange extends beyond the outer cylindrical surface of the wall 20 to provide an end abutment for the sleeve 14. Each of the

flexible members

26 and 28 has at its free end an enlarged nose portion 32 defining a shoulder 34 which projects radially outward to provide an end abutment for the opposite end of the sleeve on the core. This enlarged nose portion 32 will be seen to have a tapered outer surface 36 to enable the sleeve to be easily slipped on the core, as will appear more fully in the description that follows.

The handle 19 is an elongated hollow member which can be conveniently gripped in the hand. The core 12 is mounted on the handle so that it can rotate about its own axis and also about the longitudinal center line of the handle.

As shown in FIGURE 2, the core 12 has an integral boss 38 in the interior thereof which extends from the end wall 22. A headed fastener 41 extends through the boss, through a hole in the end wall 22 and through a hole in the end of the handle. The fastener has its integral head 42 abutting the inner end of the boss 38, and its opposite end is press-fitted into the hole at the end of the handle. Suflicient clearance between the core and the handle permits free rotation of the core about the fastener.

The sleeve 14 is slipped on and off the core over the outer end thereof by an endwise movement. Specifically, the

elongated members

26 and 28 are flexed radially inward, or towards one another, to enable the end of the sleeve to be started over the tapered nose portions 32 defined at the free ends of the members. The tapering surfaces 36 enable the sleeve to be slipped over the nose portions by a small amount of endwise pressure, and these tapering surfaces will provide a camlning action to flex the

members

26, 28 inward a little more if necessary to clear the sleeve. When the sleeve is positioned on the cylindrical wall 26 of the core in the position shown in FIGURES l, 2 and 4, the flexible members 26,

28 snap radially outward so that the shoulders 34 provide an abutment for the outer end of the sleeve. The sleeve fits snugly on the cylindrical surface of the core in coaxial relation therewith, between the flange 3t and shoulders 34. The sleeve is removed by an en-dwise movement in the opposite direction, after having flexed the free ends of the

members

26, 28 radially inward to the dotted line position of FIGURE 4.

Obviously the tacky surface of the outer convolution of the tape 18 will lose its effectiveness in time. In order to present a new, fresh surface, the outer convolution of the tape must be torn off. For thi purpose there is provided an elongated, thin, flexible, resilient strip 56 which may be of metal or plastic, for example, and might be of a gauge similar to that employed in ordinary steel measuring tapes. The strip has the arched or concave-convex cross-section, shown in FIGURE 5, throughout its length. One end of the strip 50 is permanently secured to a spindle 52 which extends across the free ends of the

members

26 and 28 of the core. The opposite ends of the spindle are reduced to provide journal portions 54 which are axially slidable and rotatable in transverse openings in the enlarged nose portions 32 of the

flexible members

26 and 28. Hence these journal portions do not interfere with the flexing of the

members

26 and 28 between the solid and dotted line positions of FIGURE 4. The strip has an opening or hole 56 near the spindle, shaped as indicated in FIGURE 4, and the opposite or free end of the strip has a narrow tab 58.

When not in use, the strip 50 is folded in a loop within the core, as illustrated in FIGURE 2, and the tab 58 is inserted through the hole 56 to releasably latch or hold the strip in this position. When it is desired to sever a length of the tape 18 from the sleeve 14, it is only necessary to manually remove the tab 58 from the hole, and withdraw the strip 50 from its position within the core by pulling straight out on the free or tab end of the strip. The strip is then laid across the end and along the length of the cylindrical surface of the core and sleeve, as shown in FIGURE 3, and with one longitudinal edge of the strip placed against the tape as a cutting edge, the tape may be torn off at any length desired. The tacky surface of the tape serves to hold the tearing strip in place when being used. Also, the underlying layers of tape hold the outermost layer and tearing strip rigidly in place, because of the characteristic tack, thereby permitting the use of a less rigid tearing strip than would ordinarily be required.

Referring to FIGURES 6-9, the device there illustrated is substantially the same as the device in FIGURES l-5, except for the means which facilitate the tearing off of a length of the tacky material, which is different in this embodiment. Accordingly, corresponding parts of the device are designated by the same reference characters.

In this embodiment, the elongated, thin, flexible, resilient strip 70 is like strip 50 previously described. In other words, it may be of metal or plastic for example, and might be of a gauge similar to that employed in ordinary steel measuring tapes. The strip 70 likewise has an arched or concavo-convex cross-section, shown in FIGURE 9, throughout its length.

The strip 70 has one end 72 permanently secured to the end wall 22 of the roller. As shown in FIGURES 7 and 9, the end wall 22 has a slot in which the end 72 of the strip 70 is disposed and secured by any suitable means. The strip 70 extends inside the roller to form its anchored end 72 within the hollow interior of the roller, and when not in use substantially the entire strip is disposed in a loop within the roller. In this inoperative or stored position illustrated in FIGURE 7, the free end 74 of the strip projects through slot 76 in the end wall 22 to the outside of the roller. The free end 74 of the strip 70 is enlarged, and preferably of a shape or size such that it will not pass through the slot 76.

In order to use the tear strip 70, the free end 74 is grasped to extend the strip from the inside of the roller, and the strip is then laid along the length of the core and sleeve, as shown in FIGURE 8. The strip will have its concave side against the tape, in the same manner as the tape 50 shown in FIGURE 5, and one longitudinal edge of the strip will serve as a cutting edge. The tape 18 may, accordingly, be torn oft" easily and at any desired length.
