Claims. (01. 85-55) This invention relates to ascrew cap, and more particularly'to a screw cap serving as a cover or cap to be applied to the top ofthe screw tohide the metal thereof and to preferably blend, or have an ornamental effect; with the material which the screw secures in place.
My invention is particularly applicable, val
thoughnot limited thereto, to the type. oft screw called a Phillips screw, which at its head is formed with a plurality of intersecting depressions adapted to receive a similarly shaped operating endof ascrewdriverwhich may be operated in a brace, or not, as desired, In automobiles, airplanes, and many other jobs a sheet or strip of facing material is applied to a backing to give to the same an ornamental :and pleasing "finish.
Thetfacing material may be of .wood, plastics, metal or other construction andis more ornamental in appearance than the backing which may also be of any desired material. The facing material is secured to the backing at suitably spaced distances by the screws referred to herein. Without .myinvention the metal of the grooved ends of the screws would be visible, and detract from the appearance of the otherwise ornamental covering material which is secured in place by the screws. However, by the application to the grooved ends of the screws, of my novel caps forming the subject-matter of the present invention, the otherwise exposed ends of the metal screws are covered up and concealed from View byan ornamental cap which may be made to fit in with any desired color or other ornamentation scheme. l
The screw caps of this invention may be made of plastic, wood, metal or other desired material which may be of any ornamental finish desired or thus constructed throughout. While not limited thereto, my invention is especially adapted to screw caps made of plastics, which are readily made in various colors andornamental effects,
. and which screw caps may be removed from the screws when it is desired to remove the screws by unscrewing the same.
' Other objects, advantages and capabilities will later more fully appear.
My invention further resides in the combina- .tion, construction and arrangement of parts illustrated in the accompanying drawing, and while I have shown therein preferred embodiments I wish it understood that the same are susceptible of modification and change without departing from the spirit of my invention.
In the drawing:
,Fig. 1 is a fragmentary front elevation of an instrument board of an automobile to which has been applied an ornamental covering secured in place by screws havingmy novel screw caps fixed thereto. w i Fig. 2 isa, perspective view of a screw adapted to have my screw caps applied 'to cover the grooved end thereof. 1 r r Fig. 3 is an enlarged perspective view of one form of screw "cap embodying my invention.
Fig. 4 is a transverse section on the line 4-4 of Fig/1 on amedian plane .of the screw cap of 3, and f'ra gmentarily showing an adjacent portionof a screw in dotted'lines.
Referring more in detail .to the drawing, one 7 term of screwladapted to have my screw can applied thereto, is shown in Fig. 2, andcompri-ses the body portion I .havinga head 2 formed with the intersecting grooves 3, '4, 5 and 6 tor receiving a similarly shaped operating endtof ascrew driver. This type of screw isgenerally referred to as a .Phillips Iscrew,j "but it is to. be understood that while my invention is especially adapted thereto, it is also applicable toot-her kinds of screws having otherutorms of grooves, the only restriction being that the grooves be of suffic-ient depth and shape to receive and hold the projections on my caps or covers.
The screw caps described will preferably be made of plastic material, although not necessarily limited thereto. Any suitable plastic may be used,
either of the thermoplastic or thermosetting type. Some of the many kinds of plastics, which are referred to merely as being illustrative and not as limiting the invention, may be mentioned as thermoplastic resins, thermosetting resins, phepol-formaldehyde, phenol-furfural, synthetic resins, Bakelite, natural resins such as lignin, vinsol and the like, and others of a similar nature, ureaformaldehyde, phenolic resins, vinyl resins, and
other resins and plastic material obtainable on the market under various trade-names. Wood, metal, composition material, or other materials may be used if desired.
In the form of my invention shown in Figs. 3 and 4, I have provided a cap head 1 of plastic or other desired material, and having embedded in or otherwise secured thereto, projections 15,
which are preferably formed of resilient metal or other suitable material with spaced apart resilient sides capable of being squeezed toward each other when the projections are'forced into the grooves of the screw head." When thus forced into the grooves thematerial of the projections will be sufliciently distorted as to grip the walls of the grooves and hold the cap in place, removable or not, asdesired. If it is desired that the caps be not removable, this can be effected by providing interlocking burrs or ears on the projection l5 and recesses inthe groove walls, or vice versa.
The cap heads may be colored, as desired, to match or blend with the covering surface being secured in place, or. plastic or other material that is inherently of the desired color effect may be used. i
My improved caps 1 are applied to cover the grooved head 2 of screws I which are screwed into threaded openings in a suitable supporting backing to hold in place the sheet of facing material IS, the screw head being tapered and fitting against correspondingly tapered sides in holes in the facing material. The facing material may be spaced from the supporting backing or not as desired. Fig. 1 shows a face view of the facing material as applied to the instrument board of an automobile. Such facing material may be applied to any construction desired.
- Having described my invention, I claim:
1. A cap adapted to cover the grooved head end of a screw holding in place a facing material, a
plurality of fastening elements embedded in the cap and projecting therefrom, each of the fastening elements being formed of resilient material U-shaped in cross-section, the projecting portions of the fastening elements being of a size and shape with relation to the grooves in the screw headthat when pushed into the grooves they will engagethe groove walls to hold the cap in place 1 on the screw and cover the screw head.
3. In a cap adapted to cover the grooved head 5 end of a screw holding in place a facing material,
a cap head, a plurality of fastening elements embedded in the cap head and projecting therefrom, each of the fastening elements being formedof resilient material closed at one longitudinal edge and open at its other longitudinal edge and forming spaced apart resilient sides that normally stand a greater distance apart than the thickness of a groove in the screw head, the projecting portions of the fastening elements beingof a size and shape with relation to the grooves that when pushed into the grooves they will engage the groove walls to hold the cap in place on the screw and cover the screw head.
4. In a cap adapted to cover the grooved head end of a screw, a cap head, a plurality of fastening elements each having a deformed end rigidly embedded in the material of the cap head, the fastening elements each projecting longitudinally out from the inner face of thecap head and being formed with spaced apart resilient side walls closed along one edge and open at the other, the sides of the projecting portions of the fastening elements along the open edge standing a greater distance apart than the thickness of a groove in the screw, whereby when pushed into the grooves the sideswill be depressed to grip the groove sides and hold the capin position to cover the screw 2. A cap adapted to cover the grooved head end of a screw holding in place a facing material, a
plurality of fastening elements embedded in the cap andprojecting therefrom, each of the fastening elements being formed of resilient material U-shaped in cross-section, the projecting portions of the fastening elements being of a size and shape a with'relation to the grooves in the screw: head that when pushed into the grooves they will engage the groove walls to hold the cap in place on ends.
