METHOD OF SECURING COMPONENTS OF A CAP MEMBER TO ONE ANOTHER Original Filed March 1, 1961.

'22 JCODM M25 20 3 2| [6 I I I5 I 4 W mun 2 E 5 I I INVENTORS 24A HENRY RUSK/N BY ERNEST S. VIOLA F-E M A T TORNE Y United States Patent 3,301,731 METHOD OF SECURING COMPONENTS OF A CAP MEMBER TO ONE ANOTHER Henry Ruskin, Bayside, and Ernest S. Viola, Westbury, N.Y., assignors to Swingline' Inc., Long Island City, N .Y., a corporation of New York Original application Mar. 1, 1961, Ser. No. 92,616, now Patent No.- 3,l56,058, dated'Nov. .10, 1964. Divided and this application Sept. 4, 1963, Ser. No. 306,433

. 4 Claims. (Cl. 156293) v This invention relatesto a method of Securing components of a cap'member to one another so as to form a cap. The instant application is a divisional application of my copending application, Serial Number 92,616, filed March 1, 1961', now US. Patent 3,156,058. The cap construction itself is claimed in the parent application. The cap of this invention finds particular application when utilized as the driver actuating portion of a staplingmachine, The capconstruction of the parent invention mayalso be employed for typewriter keys, push buttons or any other application where indicia are borne by a member and where permanency is desired.

The cap of the parent invention is simple and inexpensive to manufacture. The parts of the cap are held to one another permanently and durably. Mechanical impact upon thecap will generally not break it and the indicia are permanently readably and protectively disposed upon the cap at all times. The method of this invention produces a cap quickly and inexpensively. The cap is of pleasing appearance and looks expensive.

Other objects and advantages of the instant invention may also become apparent to the reader of this specification. v

The cap of the parent invention may be briefly described as comprising a body member having a recess therewithin and a top member having indicia thereupon disposed within said recess and 'adhesively secured thereto. The cap is preferably made of a plastic, preferably a dissolvable thermoplastic material, and the top member of the cap is preferably made of a transparent plastic. Raised indicia are preferably out into the cap portion extending upwardly from the lower surface thereof, a layer of. solvent dissolvable paint is disposed upon said lower surface, and an intermediate member preferably intervenes between the top member and the bottom of the recess within the body member.

The method of forming the cap of the instant invention may be briefly described as comprising the steps of obtaining an intermediate member impervious to the action of a solvent, which solvent should have the capacity of at least partially dissolving the paint layer upon the lower face of a top member. The intermediate member is then impregnated with the solvent and placed in overlapping relationship with the painted surface of the top member. The solvent is thereafter applied to the securable surfaces of the top member and to a body member therewithin, and the surfaces are placed in overlapping relationship until adhesive securement of the parts to one another is obtained.

The invention will be further described by reference to the accompanying drawings which are made a part of this specification.

FIG. 1 is a top plan view of the top member of this invention.

FIG. 2 is a plan view of the intermediate member of this invention.

FIG. 3 is a side exploded perspective view of the top member and the intermediatemember ofthis invention.

FIG. 4 is a plan view of the top member and intermediate member of this invention with the parts in assembled relationship.

FIG. 5 is a side exploded perspective view of the top member, intermediate member and body portion of the instant invention.

FIG. 6 is a top plan view'of the top member, intermediate member and body portion of the instant invention in assembled relationship.

FIG. 7 is a'side'view of the instant invention utilized as a cap for a stapling machine.

FIG. 8 is a sectionallview of the form of the invention shown in FIG. 6 taken along lines 88 of FIG. 6.

FIG. 9 is a sectional view of the form of the invention shown in 'FIG. 7 taken along lines 9-9 of FIG. 7.

Referring now to the form of the invention shown in the accompanying drawings for a detailed description thereof the cap 11 of this invention is formed with a top member 12, an intermediate member 13, and a body portion 14. Body portion 14 is formed with a-recess 15 which is open at the'top thereof and is formed with a bottom 16 and side portions 26.

Top member 12 bears indicia 17 (consisting in the modification shown of the words JOHN DOE) which indicia are cut into the lower face 18 of the top member 12 and extend upwardly therefrom but do not project through the upperface 19 of top member 12. Top memberlZ also has a paint layer 20 below its lower surface 18 thereof and'a downwardly extending tail portion 21 at the rear thereof. Top portion 12 is also formed with side portions 22.

Body portion 14 of cap 11, in the modification shown in the drawings, is utilized as a cap for a stapling machine and bears a support portion'23 and a driver 24 secured thereto. However, it is pointed out, that the cap construction of this invention could also be applied to other devices by obvious modifications of the construction thereof.

Body portion 14 of cap 11 is preferably made of cellulose acetate butyrate resinous material and top member 12 made of the same material. In the preferred modification top member 12 is substantially transparent.

Intermediate member 13 is preferably made of a fibrous material such as cotton, paper and the like. Generally intermediate member 13 is woven into such design as will serve as proper background material for indicia 17.

With the foregoing description of the instant invention, the method of making the same will now be explained.

Body portion 14 is prepared with a recess 15 therewithin, top portion 12 with indicia cut thereupon, and intermediate portion 13 are also prepared. Top member 12 is thereafter painted on its lower surface preferably with a conventional lacquer paint so that the indicia 17 appear to have a three-dimensional aspect within top member 12. The above steps are conventional and well known in the art. Intermediate member 13 is then dipped into a material which Will partially dissolve paint layer 20 and is applied, in a proper fixture, to paint layer 20 so that, where intermediate portion 13 has a woven effect, top member 11 will take the woven appearance of intermediate portion 13 as indicated in FIG. 4.

Where the paint used constitutes a lacquer, acetone is the solvent employed.

The application of intermediate member 13 to top member 12 must be very carefully done and both portions should be brought together in a fixture at right angles to their longitudinal axes and carefully.

After the above assembly is carried out, and where cellulose acetate butyrate is employed as the plastic, ethyl acetate is then applied to the side portions 22 of top member 12 and to the bottom and side portions of recess -15.

This step partially dissolves the plastic. The parts are then carefully brought together in a fixture at right angles to their longitudinal axes and held into position until adhesive securement of all three members is obtained.

Before concluding this specification some of the terms used herein and in the appended claims must be specially defined since the meanings used are somewhat at variance with the technical definitions thereof.

The term dissol-vable, as: usedto define .the paint used herein, means that the adhesion of the paint to the surface upon which it is applied maybe broken.

The term dissolvable as used to define the plastic which is used to manufacture parts of the instant invention, meansthat such plastic canbe softened and made sticky so that one member can be adhered to the other member.

The term solvent, as used in this specification, means a material which can break the adhesion of the paint to the surface to which it is applied and/ or which can soften the plastic parts of the instantinvention.

The foregoing specific modifications of the inst-ant invention as set forth in the specification herein are for illustrative purposes and for purposes of example only. Various changes and modifications may obviously be made Within the spirit and scope of this invention and would occur to those skilled in this art.
