Fizz? ,Zd/dZd 7/. BY /%W 77 wz/si United States Patent 3,177,512 TYPE CLEANING DEVICE Philip Balaban, 19500 Sorrento, Detroit 35, Mich. Filed Apr. 3, 1962, Ser. No. 184,877 4 Claims. (Cl. 15-104) This invention relates to cleaning devices, and particularly to a rotatable type cleaning device having a renewable tacky peripheral layer thereon.
removes the lint and particles of material from the face of the type. The device embodies a handle having a stub shaft extending therefrom on which a cylindrical body is rotatably supported. The body has a transverse slot therein for receiving one end of the tape which is wound thereon. The tape which encompasses the roller has a tacky surface and an extending portion with an adhesive face. The adhesive face projects through the slot of the roller and secures the tacky strip on the outer periphery thereof. One end of the tacky strip is secured to the adhesive strip to which the opposite end is secured when the ends are in abutted relation. The adhesive strip joins the abutted ends of the tacky strip together in cylinder form and retains it fixed to the surface of the roller. By grasping the handle and running the roller over the type or other element, any particles in the recesses thereof are picked up by the tacky surface and are removed therefrom. The type or other element is maintained clean by the use of the roller and a perfect impression is obtained thereafter on the paper when the type is imprinted thereon through the printing ribbon.
Accordingly, the main objects of the invention are: to provide a cleaning device having a cylindrical tacky surface which removes lint and particles which accumulate in recesses of an element; to provide a handle with a protruding stub shaft on which a hollow roller having a center sleeve is rotatably supported for applying a tacky surface to type face for removing particles therefrom; to provide a handle having a laterally extending stub shaft with an enlarged head over which a flexible sleeve at the center of a roller is forced and retained for rotation on the shaft to have a tacky surface thereon pick up particles of material collected on the face of elements which are cleaned thereby, and, in general, to provide a cleaning device which is simple in construction, positive in operation and economical of'manufacture.
Other objects and features of novelty of the invention will be specifically pointed out or will become apparent when referring, for a better understanding of the invention, to the following description taken in conjunction with the accompanying drawing, wherein:
FIGURE 1 is a perspective view of a type cleaning device embodying features of the present invention;
FIG. 2 is an enlarged sectional view of the structure illustrated in FIG. 1, taken on the line 2-2 thereof;
FIG. 3 is a sectional view of the structure illustrated in FIG. 2, taken on the line 33 thereof;
FIG. 4 is a broken plan view of a tacky strip which is applied to the periphery of the roller of the device of FIG. 1; and
FIG. 5 is a broken sectional view of the structure illustrated in FIG. 4, taken on the line 55 thereof.
In the figures, a disk portion at the end of a handle 11 has a stub shaft 12 extending outwardly therefrom. The stub shaft has a slightly enlarged head 13 for locking a roller 14 thereon. The disk, handle and stub shaft are a unit which is preferably molded from metal, plastic or other material in a die having a recess of like form. The roller 14 is hollow having a peripheral wall 15 and a centrally disposed sleeve 16 joined by a web at one end. The plastic material of the roller is of a flexible type, such as polyethylene, polypropylene and the like, which permits the sleeve to expand over the head 13 when forced onto the stub shaft 12. The head locks the roller on the stub shaft against outward movement. A shoulder 17 at the inner end of the stub shaft 12 is abutted by a corner 18 at the inner end of the sleeve 16. The roller 14 is freely rotatable on the stub shaft 12 after being assembled thereon.
The peripheral wall 15 has a slot 19 thereacross through which an end of an adhesive strip 21 secured to one end of a tacky strip 22 extends for engaging the inner peripheral wall of the roller to which it adheres. The strip 22 is then wound around the outer surface of the wall 15 and abutted against the end adhered to the strip 21 to which it is secured.
The tacky strip 22 is illustrated in FIGS. 4 and 5 as having ends 23 and 24 the length therebetween being equal to the peripheral length of the outer surface of the wall 15 of the roller. The adhesive strip 21 is secured to the undersurface of the strip 22 adjacent to the end 24 leaving the extending end 26 covered by a removable protecting layer 27. The layer 27 is removed when the tape is to be employed so that a portion of the end 26 may extend through the slot 19 in engagement with the inner surface in a manner to have the other portion thereof facing upwardly on the outer surface of the roller adjacent to the slot 19. The end 23 of the strip 22 engages the upwardly facing portion of the strip 21 when abutted against the end 24. The strip 22 is maintained in cylindrical form on the surface of the wall 15 secured against rotation thereon by the portion of the strip 21 adhered to the inner surface of the wall of the roller.
When the strip 22 has been applied to the outer surface of the wall 15 of the roller 14, it is moved over the face of the type by the manipulation of the handle 11 advancing the roller thereof. A slight pressure on the roller urges the tacky material of the strip 22 downwardly thereof so as to extend in areas downwardly from the top thereof into contact with any foreign particles which may have collected on the type face or other elements having recesses therein. The tacky material on the face 22 is of substantial depth and of such a nature as to be usable repeatedly without leaving any residue upon the face of an element being cleaned. The material in the recesses of the element is picked up by the tacky surface and removed therefrom. Only after extensive use will it be necessary to remove the strip 22 and apply a fresh strip to the roller by a simple operation which is performed in a very short time.
What is claimed is:
1. In a device for cleaning the type face of a typewriter, an element having a body from which a stub shaft extends in one direction and a handle extends in another direction, said stub shaft having an enlarged integral end thereon, a roller having a slotted peripheral wall, a single end wall and a central flexible sleeve extending within said peripheral wall from said end Wall, said sleeve extending over the stub shaft for rotation thereon and secured by said enlarged end, said sleeve being adapted to be flexed when passed over the head of said stub shaft, and a strip of material having a main portion of tacky material and an edgewise projecting adhesive edge portion, said edge portion extending through the slot of the peripheral wall and adhering to an inner portion of the roller and having a portion which secures the opposite end of the strip to the adjacent end thereof when in engagement with the 7 outer peripheral surface of the roller.
