JACKETED ROLLER-TYPE LINT REMOVER Filed June 20, 1967 l/VVEJVOL Frank 5. 711M157 United States Patent 3,421,170 JACKETED ROLLER-TYPE LINT REMOVER Frank S. Thomas, Jr., 1715 Camden Ave., West Los Angeles, Calif. 90025 Filed June 20, 1967, Ser. No. 647,391 US. Cl. -104 Int. Cl. A421 /00 6 Claims ABSTRACT OF THE DISCLOSURE Related application My co-pending Patent No. 3,363,276, granted Jan. 16, 1968, discloses certain subject matter bearing some relation to the present lint removerapplication.
Background of the invention This invention relates to tacky surface lint removers in general and is particularly directed to providing a tacky roller for lint removal which may be effectively covered during non-use and hence protected from inadvertent contact with its tacky surface, but the covering means of which may be readily removed therefrom.
In recent years there have been developed a number of different types of devices which present tacky surfaces for the removal from fabrics of lint, hairs and other detachable foreign matter. One such device is illustrated and described in United States Patent No. Re. 25,435, issued to Francis P. Norman. The Norman device, however, is pretty much a oneshot lint remover. After the tacky surface has been applied a few times to fabrics, it tends to lose its tackiness and must be discarded.
In an effort to provide a more re-useable type of tacky lint remover, a number of designs have been contrived to employ a roll of tape having an outwardly tacky coating. One form of roller type lint remover employing such a tacky tape is illustrated and described in my aforementioned copending application, Ser. No. 496,787, now Patent No. 3,363,276. The roll of tape is journalled on some type of shaft or spindle and the tape cylinder with its tacky surface is rolled over fabric areas which it is desired to have cleaned of lint, hairs and detachable foreign matter on the fabric. However, after a certain amount of such rolling, the exposed tape surface loses its tackiness and one circumference of the tape must be peeled from the roll and cut off before re-use.
More recently there have appeared on the market a number of roller type lint removers which do not utilize any tacky tape rolls, but instead, employ cylinders which are coated with a tacky substance. These tacky coated cylinders are employed in the same manner as the tape type rollers described above, but when the tacky coating adsorbs a certain quantity of lint, hairs and foreign matter, the cylinder must be scrubbed with soap and water to remove the thus-picked up lint, hairs, etc. When the water is shaken off, the cylinder will again be found to be tacky and capable of re-use as a lint remover.
Both of these two types of roller lint removers, however, have required provision for some type of removable yet re-useable covering for the exposed tacky surface of 3,421,170 Patented Jan. 14, 1969 the cylinder (whether in the form of a tape roll, or washable substance). What has generally been employed is either a metallic surfaced flexible sheet with minimum adherence to the tacky surface of the cylinder, or some other type of flexible sheeting which can be wrapped around the cylinder and peeled off when a person desires to re-use the lint remover. These sheet-type coverings have generally been unsatisfactory since the sheet may become torn or lost. Manufacturers of tape-type roller lint removers generally solve this problem by supplying a new covering sheet wtih each replacement roll of tape, hoping that the sheet will not become lost or torn before the tape roll is completely used up. Such a solution is not available to those manufacturers of the permanently tacky cylinder types of lint removers. One manufacturer of the latter type of lint removers, therefore, has attempted to provide the necessary covering for his tacky cylinders by an elaborate closeable housing for the cylinder which housing, when opened up, serves as a handle as well as a mounting for journalling the tacky cylinder and exposing the latter for use. Such a housing is not only complicated and subject to being broken, but must be expensive to manufacture since the price of this lint remover is several times that of the tape-type roller lint removers.
Summary of invention The present invention provides a roller type lint remover construction which is adapted to employ either the tape roll or the permanently tacky cylinder as the lint pickup device and includes a cylindrical sleeve-like plastic jacket which serves to cover the exposed tacky surface of the tacky cylinder during non-use, thus obviating the necessity of applying a metallic or other flexible sheet to the tacky surface at the conclusion of useage to prevent such surface from coming into unwanted contact with some other object. To dispose the sleeve-like jacket in such a manner that the inside wall of the jacket is maintained out of contact with the tacky surface of the roll or other tacky coating on the cylinder, the tacky roll or other cylindrical element is supported at its ends by a pair of flanged discs having rims with outside diameters at least slightly greater than the outside diameter of the roll or other cylindrical element. These discs are centrally orificed and serve to journal the assembly on a shaft or spindle which, in turn, is supported by a handle. The inner wall of the sleeve-like jacket is coated wtih a silicone to inhibit any adherence of that wall to the tacky coating on the cylinder which the former protects from unwanted contact.
It may thus be seen that the construction of the present invention is readily adaptable for use with either the tape lint remover or the permanently tacky cylinder lint remover. Among its further advantages are its economy in manufacture, the relative indestructibility of the covering for the tacky surface, the facility with which the sleeve-like jacket may be removed and replaced, and its aesthetic appearance.
Description of the drawing In the accompanying drawing:
FIG. 1 is an elevational view of the complete assembly of the preferred embodiment of the invention.
FIG. 2 is an exploded view in perspective of the assembly of FIG. 1.
FIG. 3 is a section on the lines 33 of FIG. 1.
Description of the preferred embodiment Referring to the drawings for an illustration of the preferred embodiment of the present invention, a handle 10 is integrally molded of plastic, such as medium impact polystyrene, with a shaft or spindle 12 which is thereby firmly supported by the handle. The outermost extremity of the shaft is provided with an enlargement 14, the function of which will be explained at a later point in this specification.
There is then rotatably mounted on the shaft or spindle 12 an assembly 15 which comprises a tacky cylindrical element 16, a pair of supporting flanged discs 18, 2t) and a sleeve-like cylindrical jacket 22, the detailed construction, functions and interrelationship of all of which are as follows: In this illustrated embodiment, I have shown as the tacky lint pick-up cylindrical element the one which is provided with the permanently and washable tacky surface of the type more recently marketed by several manufacturers and which per se does not comprise any part of the present invention. It should be understood, however, that there could be substituted for such permanent and washable tacky surface type cylindrical element, one of the tacky tape type rolls which have been on the market for several years and is shown and described in my aforementioned prior co-pending application Ser. No. 496,787.
The element 16 is rotatably supported on the shaft or spindle 12 by a pair of polystyrene discs 18, 20, each of which includes a flat centrally disposed radiating portion 24, an axially extending portion 26 and a radiating flange portion 28. The portion 24 is centrally orificed at 30 to enable the shaft or spindle 12, including its enlargement 14, to be passed therethrough and to serve to journal the assembly 15 on the shaft or spindle 12. The polystyrene or other plastic material selected for molding the discs 18, 20 should be sufliciently flexible after molding to permit enough distention of the discs under modest hand pressure to permit the enlargement 14 of the shaft to be passed through the orifices 30 in the discs. However, after the enlargement 14 has passed through both discs as shown in FIG. 3, the enlargement serves to prevent retraction of the shaft 12 through disc 18, until modest withdrawal pressure is applied for that purpose.
The axial portion 26 of the discs 18, 20 has an out side diameter approximately equal to the inside diameter of the cylindrical element 16, thereby to enable each of said discs to be forcertted within the hollow area of the element 16 to the point where the end of the latter abuts the radiating flange portion 28 of the disc. This radiating flange portion 28 not only serves as a limit for the insertion of the disc into the hollow area of the cylindrical element 16, but by its radial dimension further serves to support the sleeve-like jacket 22 a sufi'icient distance from the outer tacky surface 32 of the element 16 to permit the jacket 22 to be axially moved back and forth across the surface 32 without adherence thereto. The jacket 22 may be molded of a flexible polystyrene or polyethylene and, if coated with a thin layer 24 of silicone, will not adhere to the tacky surface 32 even though separated therefrom by only .025". The latter dimension may therefore be selected as the excess of the radius of the radiating flange portion 28 over the radius of the element 16 (including its outermost tacky coating 32). The advantage of employing such a very small radial differential is that the flexible sleeve-like jacket 22 may be molded of a relatively thin wall and still receive some support from the tacky coated cylindrical element 16. With the silicone coating 34, it will be found that even when the sleeve is squeezed radially inwardly to the point of contacting the tacky coating 32 on the element 16, when released, the memory of the plastic will draw the sleeve wall radially outwardly and off of the tacky coating 32.
When thus maintained in a disposition not in actual contact with the tacky surface 32, the plastic sleeve 22, the inside diameter of which is slightly in excess of the outside diameter of the rim of the flange portions 28 of the discs 18, 20, may be moved axially with respect to these rims and the tacky coated surface 32 of the element 16. To prevent the sleeve from being pushed over tit) In use, a roller type lint remover constructed in accordance with the present invention may be readily assembled by simply snapping the roller assembly onto the shaft or spindle 12 and then sliding off of the cylindrical element 16 the jacket 22. With this construction either a tape type tacky roll, or the newer washable tacky cylinder may be employed as the cylindrical element 16. The tacky surface is at all times protectable by simply sliding over it axially the flexible sleeve-like plastic jacket 22, and the latter not only is relatively durable, but is easy to remove and replace, has a neat appearance, is inexpensive to manufacture, and does not adhere to the tacky surface of the actual lint removing roll.
There will undoubtedly occur to persons skilled in this are many variations in materials, dimensions and constructional details for embodiments of the present invention but I intend to comprehend all such variations within the scope of the following claims to this invention.
