PRINTING DEVICE Original Filed Aug. 25, 1964 Jerome H.Leme|son United States Patent C) 3,468,252 PRINTING DEVICE Jerome H. Lemelson, 85 Rector St., Metuchen, NJ. 08840 Original application Aug. 25, 1964, Ser. No. 391,882. Divided and this application Aug. 8, 1967, Ser. No. 660,566

Int. Cl. B41f 17/00 US. Cl. 101--379 8 Claims ABSTRACT OF THE DISCLOSURE A printing device is provided which includes a printing cut or stamp preferably of the self-inking type, and a protective housing which is open at one end and surrounds the printing cut so as to protect same and normally prevent its contact with surfaces surrounding the device. The housing or jacket, in one form of the invention, is made of a resilient plastic material and is longitudinally displaceable when the front end thereof is engaged against a surface so as to permit the printing device supported within said housing to engage said surface. As a result, the ink wetted surface of the printing device will not normally rub or make contact with surfaces surrounding the printing device when it is not in use so as to prevent soiling objects in the vicinity of the printing device.

In another form, the printing device is supported on a member which is movable within a. cavity or opening in a housing so as to permit the printing cut to be projected therethrough against the surface disposed immediately adjacent the end of the printing device either by the momentum of the support for the printing device or other means.

RELATED APPLICATIONS This is a division of application Ser. No. 391,882, filed Aug. 25, 1964, now abandoned, having as a parent application Ser. No. 797,001, filed Feb. 12, 1959, now US. Patent 3,147,011.

SUMMARY OF THE DISCLOSURE This invention relates to a printing device which may have various uses which may include its use as a hand stamp for providing impressions or imprints on paper and other articles by the manual applications of the device to the desired surface and in various other fields including toys and games where the device may be thrown or ejected against a surface to receive an imprint thereof.

It has been known in the art to produce a hand impression device such as a so-called hand held rubber stamp unit which generally includes a handle and the support for a rubber pad or cut shaped to provide the desired print or impression of a Word, phrase or other indicia on a surface when the rubber cut is properly coated with ink. These devices require that the rubber cut portion of the stamp be applied to an ink bearing member such as a so-called stamp pad to apply a sufficient film or coating of ink on the rubber cut portion to permit the outline thereof to be imprinted on a surface when brought to bear against it. Rubber stamps of this type generally do not require means for protecting the cut portion thereof since, after one or two impressions, the ink film is generally used up and, shortly thereafter, the remaining ink either evaporates of dries up.

This invention employs a printing cut made of a selfinking material which contains printing ink encapsulated within the cells or pores of the flexible plastic, which ink may be brought to the surface of the cut by pressure applied to said flexible member such as when it is brought to bear against a surface to receive the desired impres- 3,468,252 Patented Sept. 23, 1969 sion or print. One suitable material is known commercially as Porelon plastic which is manufactured by the S. C. Johnson and Son Corporation of Racine, Wis. This material may be cast or otherwise molded to any suitable shape such as the shape of one or more letters or numbers and may be applied as a flexible blanket or cut to a support so as to serve as a printing device similar to the wellknown rubber stamp but which does not require the application of the cut to an ink pad as it self-contains its own printing ink which may be dispensed from the surface thereof by bearing said surface against the surface to receive the ink. However, such a material has an inherent short coming resulting from its ability to provide a substantial amount of printing ink on all of its surfaces whenever pressure is applied thereto. As a result, a device employing a blanket or cut of such ink containing material, must necessarily be carefully handled and hung or otherwise supported so that the ink bearing portion thereof will not engage other surfaces when not in use. The weight of gravity may be sufiicient to cause a substantial amount of ink contained within the porous ink-bearing plastic to be dispensed therefrom and to flow against and across a surface against which it rests. This may not only cause a substantial amount of the ink to be used but will also smear and stain the surface against which the printing cut rests.

Accordingly, it is a primary object of this invention to provide a new and improved printing device employing a self-inking or ink-bearing porous flexible printing member and suitable protective means therefore which normally prevents dispensing of ink from the member by preventing contact of the member with adjacent surfaces until the device or assembly is properly aligned and handled to effect the desired printing operation.

Another object is to provide a printing device which does not required the application of a printing portion thereof to an ink supplying member or pad yet which may be handled easily without normally dispensing or smearing printing ink therefrom. Another object is to provide an assembly of a self-inking or ink-containing printing cut and a protective means therefore which does not prevent use of the cut yet which permits the cut to be handled and carried in the pocket without smearing the ink of the cut on the clothing of the user.

Another object is to provide a new and improved printing device which is easily portable and does not require that it be disposed at a particular attitude or hung up when not in use to prevent ink contained thereon from smearing or transferring to other surfaces. Another object is to provide an assembly of a selfmking printing member and a protective means and support therefore which may be applicable to games and other devices.

With the above and such other objects in view as may hereinafter more fully appear, the invention consists of the novel construction, combination and arrangement of parts as will hereafter be more fully described and illustrated in the accompanying drawings, wherein are shown embodiments of this invention, but it is to be understood that changes, variations and modifications may be resorted to which fall within the scope of the invention as claimed.

In the drawings:

FIG. 1 is a partial view with parts broken away for clarity of an assembly of components defining a printing device having a movable printing member which is normally retracted within said device;

FIG. 2 is a fragmentary view in cross section of a modified form of the device illustrated in FIG. 1;

FIG. 5 is a side View of the end portion of a printing device having a longitudinally deflectable sponge or foamed plastic cover for the printing cut;

FIG. 6 is an isometric view of a printing device falling in the purview of this invention and having the shape of a ball or sphere containing a plurality of cavities in its outer surface, each of which cavities contain a printing member movable therein and FIG. 7 is a fragmentary view in cross section of a portion of the device illustrated in FIG. 6.

There are shown in FIGS. 1 to 7 various constructions in printing devices which may utilize the printing materials hereinabove described for applying an ink imprint on a surface. More specifically, the embodiments illustrated in FIGS. 1 to 7 may be applicable to various toys, games and manually operated printing devices, including printing stamps, impart printing toys, darts and the like.

In FIG. 1 is shown a structure in a printing device comprising an assembly 30 including a base 31 having a centrally disposed bore or cavity 31H in one end thereof. Slidably retained within said bore and axially movable is an assembly 32 of a piston-like member 33 and a printing member 39 disposed in its own base or mount 36. The forward end 34 of member 33 has a bore therein which is threaded to receive the threaded rear portion of mount 36 for printing member or cut 39. The member 39 may comprise a putty-like material as described or any suitable printing cut adapted to receive printing ink on its exposed outer face or retain a quantity of printing ink therein. For example, the member 39 may comprise a porous material such as Porelon containing a printing ink which will leave an impression on a surface against which 39 is abutted.

The assembly 32 is normally retained retracted in the position illustrated in FIG. 1. A nose member 38 XS thread-ably secured to a threaded extension of the forward end of member 31 and has a bore 37 therein through which the nose or mount 36 of assembly 32 is movable and retracted so as to present the surface of 39 inward of the outer surface of the end of 38 as illustrated. A coil spring 35 serves to normally urge movement of assembly 32 to retain said assembly completely within bore 37, as illustrated. The inertia of the assembly 32 provided when assembly 30 is suddenly moved towards a surface 18 operative to compress spring 35 and move the assembly 32 and cause the forward face of 39 to strike said surface. Such an action will require the sudden direction of the end of the assembly 30 against a member containing the surface to receive the imprint whereafter assembly 32 will be retracted by the spring 35 to retract the forward end of 39 inside the outer surface of 38, thus serving to prevent engagement of 39 against any surface disposed immediately adjacent the end of the assembly 30.

In FIG. 2 is shown a modified form of the invention which includes an assembly 40 of a base member 41 having its forward end 42 shaped to frictionally retain a selfsupporting sleeve 43 therein. A groove 41' circumseribing the end of 41 is operative to receive a beaded formation 44 projecting inwardly from the inner surface of 43. The forward end of 43 has an opening for aperture 45' therein and disposed immediately inside of said aperture in a printing member 39 as described secured on its own mount 47 which is secured to a cantilevered spring 46 which is movable when inertially urged by the movement of 47, a degree permitting the forward face of 39 to engage a surface against which the end of 43 is suddenly 4 struck. Notation 48 referes to a bore in the forward end of base 47 for 39.

The printing device 50 of FIG. 3 consists of a base member 51 having a retainer 54 for an ink containing printing cut 39 secured to the forward end 57 of 54 and projecting therefrom. At least partly surrounding the retainer 54 and projecting just forward of the printing cut 39 is a protective cover 58 which is made of an easily deformable material such as a flexible vinyl or polyethylene plastic which will deform both outwardly and rearwardly when the forward end 58' thereof is brought to bear against a surface which is to receive the imprint so that the end or printing face of 39 is permitted to engage the surface. As illustrated, the forward face of printing material 39 is normally disposed in a plane inward of the plane of the end face 58 of defiectable member 58. FIG. 3 illustrates in dashed notation how the wall of member 58 deflects outwardly and rearwardly to permit the front face of member 39 to project beyond the end of 58 to engage the surface to receive the imprint.

In a form of the device illustrated in FIG. 3, the side wall of the cover member 58 may be shaped to permit easy deflection thereof as illustrated at 58". In another form, the wall of 58 may be divided longitudinally to define a plurality of wall sections which will outwardly and rearwardly deform to permit the printing member 14 to abut a surface to receive the imprint thereof, yet will retain the shape illustrated after removal of the front end 58 from the surface receiving the member. Notation 59 refers to the beaded rear end of member 58 which is shaped to be frictionally retained when forced over the forward end of the base member 51, preferably being retained in a grooved 53 therein. Said base member 51 may include a handle or other means for effecting the prepositioning of the printing device relative to a surface to receive an imprint. If retainer member 54 is frictionally retained in a cavity or recess in the end of base member 51, then the assembly illustrated in FIG. 3 may be disassembled for replacement of retainer 54 with another similarly shaped retainer having either a different printing member retained against the end thereof or a replacement printing member for the member 51 when it is used up or in the event that it should become damaged. In other words, the assembly illustrated in FIG. 3 may be utilized in a variety of different manual or automatically operated printing devices where it is desired to replace cuts or type.

There is shown in FIG. 4 a printing device 60 consisting of a support or base member 61 which is preferably made of rigid material such as plastic or wood and having a forward end 64 on which is secured a printing cut 39 having a forward end or face in the shape of the desired imprint. The cut 39 is preferably made of flexible, ink containing material and is adhesively bonded or otherwise secured at its rear face to the front face of the forward end of support member 61. The cut may also be otherwise secured to the forward end of member 61, preferably in a manner so as not to normally compress the material thereof which contains ink within the cells of the material as said material is of a character as described and comprises a micro-porous plastic opertive such that said ink may be forced to flow to the surfaces of the plastic when the plastic is compressed. US. Patent No. 2,777,824 describes a flexible plastic material which may be formulated to encapsulate a variety of liquids such as inks which may be dispensed upon compression of the material against a surface.

Disposed adjacent to the compressible printing cut 39 and secured to the forward end of base member 61 is a deflectable member 65 which is preferably made of a suitable flexible plastic material such as polyethylene, polyvinyl chloride, polypropylene, or the like. Member 65 is shown having a side wall 66 shaped with a plurality of deflectable accordion-like portions 67 and preferably, although not necessarily, circumscribes the printing memher 39. The forward end of deflectable member 65 normally protrudes beyond the end-face of the printing cut 39 and the side wall thereof normally protects the face or side walls of the cut 39 from making surface contact with objects which the device 61 may rest against while on its side or when positioned with the end thereof disposed downward.

The rear portion 62 of member 64 may be secured by any suitable means to the forward end of base member 61 such as by frictional retention thereon, adhesive bonding or by means of fasteners. It is shown with a beaded formation 69 frictionally engaged in a circular groove provided in the cylindrical surface of 61.

FIG. 15 illustrates another structure in a printing member which includes an ink containing portion or cut of the type described. The assembly 70 includes a base member 71 having a forwardly projecting portion 74 against the face 75 of which is adhesively bonded a printing member 76 of the ink containing type described. Laterally disposed around portion end 72 of 71 and member 76 is a member 77 made of highly flexible plastic such as sponge rubber, cellular flexible polyurethane, vinyl or the like. The member 77 extends just beyond the front face of ink containing plastic member 76 and has lateral portions disposed adjacent 76 which serve as means for preventing contact of 76 with adjacent surfaces until 77 is longitudinally compressed when 70 is urged in the direction of a surface abutting the front face 78 of 77. The material comprising 77 is such that it will return to its normal shape so that the front face 78 thereof will normally protrude beyond member 76 as illustrated. The member 77 may completely circumscribe member 76, protrude partly there-around or may be segmented or provided as a plurality of portions which normally prevent contact of the forward face of 76 with a surface adjacent 78.

FIGS. 6 and 7 illustrate details of a printing device 80 in the shape of a ball or sphere having a shell 81 shaped witth a plurality of indented portions 83 each of which supports a mount 86 for a printing member as described. The bore defined by indented portions 83 permits the axial movement of the assembly including mount 86 and printing member 87 when the ball is directed against a surface at the proper attitude to cause 86 to inertially project printing member 87 beyond the surface defined by wall 81. Member 86 is movably secured to a projection 84 from the bottom of formation 83 by means of a coil spring 85 secured to both. The structure illustrated in FIGS. 6 and 7 may be applied to others of the illustrated structures without departing from the spirit and scope of the invention and the various other structures may also be partially or totally interchanged with each other to provide printing devices and structures operative to protect a printing member from objects which would ordinarily engage the surface of the member without said protection yet are also operative so as not to prevent the movement of the printing member in a manner to effect an imprint on a surface thereby when necessary.
