United States Patent 2,998,777 PERCUSS'IVE CAP STRUCTURE John W. Ryan, 11027 "Cashmere Sh, Bel-Air, Calif. Filed Feb. 9, 1959, Ser. No. 791,983 4 Claims. (Cl. 102-865) This invention relates to a percussive cap structure for use particularly in a toy gun.

This invention provides for a percussive cap for use in a single shot or repeating cap pistol, which can be pre-cut to a desired configuration, preferably circular, and held on a strip or sheet of paper or other suitable material by pressure-sensitive adhesive means until removed therefrom for use in the cap pistol or optionally for use while still adhered to the strip or sheet. This invention embraces the use of a pressure-sensitive adhesive material either on the cap itself, or on the backing sheet or strip, whereby, in one form, the cap having a pressure-sensitive adhesive material on one of its faces is self-retaining on the anvil, or optionally on the hammer,

of the toy pistol to be fired as by striking thereof by the hammer of the pistol; or, in another form, the sheet or strip having a pressure-sensitive adhesive material holding the caps thereto is retained on the anvil 6f the toy pistol by means inherent with the pistol; or, in yet another form, the pre-formed cap may be separated from a strip having a pressure-sensitive adhesive material on a face thereof and held on the anvil of the pistol by any suitable means provided in the pistol.

In its preferred embodiment, the invention provides a sheet having pressure-sensitive adhesive material secured on one surface thereof, and one or more charges of fuhninating material, such as gun powder or the like, secured to the opposite face of the sheet and a circular, endless cut made through the sheet, encircling the fulrninating material, whereby the portion of the sheet inside the circular cut and having the charge thereon may be removed from the sheet for self-securement to the anvil of the toy pistol.

Toy pistols, in the past, have been formed with various types of anvils, the more common of these being a fiat seat formed integral with the body of the pistol against which the hammer strikes to fire the cap, a revolving anvil having a fiat side or outer peripheral surface engageable by the hammer of the pistol, or a removable simulated cartridge having a fiat end engageable by the hammer of the pistol. Any of these anvils are suitable for the use of an explosive cap in accordance with this invention. To achieve greater realism, children now prefer to simulate actual loading conditions which is, in reality, an action involving loading individual explosive cartridges within the chamber of the gun. To simulate such action, an individual cap is preferred. However, such individual caps have in the past been cumbersome to handle, to insert into the gun, and to store. Handling of such caps frequently results in spilling or dropping thereof with defacing or loss thereof.

It is therefore an object of this invention to provide a new and improved percussive cap structure in which an individual cap, having a fulminating charge incorporated therein, is easily and securely stored until use, is easily and quickly accessible for use and easily insertable into a toy gun for detonating of the charge by the striking action of the hammer of the gun.

Another object of this invention is to provide a new and improved cap structure in which the individual charges may be secured to a sheet or strip in any desired spacing and used by feeding the strip or sheet on the anvil in any suitable manner provided within the gun.

A further objects of this invention is to provide a new and improved percussive cap structure which is economical to manufacture and capable of mass production.

A general object of this invention is to provide a new,

andimproved percussive cap of the character described which overcomes disadvantages of prior means and meth-' ods heretofore intended to accomplish generally the same purpose.

These and other objects of this invention will be more apparent from the following drawings, detailed descrip' tion and appended claims.

In the drawings:

FIG. 1 is an enlarged fragmentary view, in perspectiv,

of a cap structure designed and constructed in accordance with this invention;

FIG. 2' is a vertical, cross-sectional view as taken substantially along a line 2-2 of FIG. 1;

FIG. 3 is an enlarged perspective view of an individual cap forminga part of the structure illustrated in FIG. 1,

with a portion thereof broken away for greater clarity;

FIG. 4 is a fragmentary view, illustrating one application of the cap structure of the instant invention, with parts broken away for greater clarity; and a FIG. 5 illustrates another application of this invention; FIG. 6 is a fragmentary perspective view illustrating yet another application of this invention.

. Referring more particularly to the drawings, there is The first sheet 11 is removably secured to the second.

sheet 12 by a pressure-sensitive adhesive material 13 provided on an adjacent face of at least one of the sheets 11, 1 2 for temporarily securing one sheet to the other.'

As used hereinafter in this specification and in the claims, the term pressure-sensitive adhesive shall be deemed to refer to an adhesive material that readily adheres to a surface against which it. is pressed but which may be readily separated therefrom by pulling and without tearing or damage to the members held together thereby. Such pressure-sensitive adhesives are well-known and need not be described in further detail.

The sheet 11, as herein illustrated, is provided with at least one, and preferably a plurality of charges '14 of 'a fulminating material, such as commonly used in toy caps and comprising a chlorate-sulphide-phosphorous compound or the like. The charges '14 are secured in spaced relationship on the sheet 11 as by an upper sheet 16 of a relatively thin flexible material, such as paper or the like, secured permanently to the sheet 11 asby a permanent adhesive. The sheet 16 is secured against the sheet 11 at portions 17 surrounding the charges 14 thereby to completely enclose the charges 14 and sandwich them between the

sheet

16 and 11 within pockets 18 formed therebetween. The pockets 18 may be optionally pre-formed, if desired, or formed during the operation of securing the sheet 17 to the sheet 11, the sheet 16 being substantially more flexible than the sheet 11 and thereby forming a bulge, as best seen in FIGS. 2. and 3.

An endless cut 20, preferably circular in configuration, is formed around each charge 14 and spaced therefrom and extending through the

sheet

16 and 11 to form discrete cap units referred to by the numeral 19, each unit being removable from the sheet 12 as by lifting of one edge thereof and peeling away'from the sheet 12, as indicated by cap 19' of FIG. 1.

The pressure-sensitive adhesive material 13 is preferably secured to the face 21 of the sheet 11, opposite the face 22, upon which the charges 14 are secured. In' this maner, discrete cap units 19 removed from thesheet 11 retain the layer of pressure-sensitive adhesive material p 3 13 secured thereto, whereby the cap unit 19 may be secured, 'by pressing, to any suitable anvil of a toy pistol for detonation of the charge 14 by the striking force of a hammer of the pistol against the anvil. Each sheet may be optionally provided with pressure-sensitive material on adjacent faces, if desired.

Referring to FIG. 4, a portion 23 of a pistol is shown having an anvil 24 integral with the pistol and having a relatively flat face 25 on which a cap unit 19 may be temporarily secured by pressing the cap unit 19 on the face 25 with the pressure-sensitive adhesive material in contact with the face 25 and aligned with the hammer 26 of the gun. Actuation of the hammer 26 to strike an anvil 24,, causes the charge 14 embedded between the

sheets

11 and 16 to detonate.

If desired, the pressure-snsitive material may be secured to the sheet 12, whereby cap units removed therefrom retain little if any of the adhesive material. In the instant form, a cap identical to the cap 19 but without pressure-sensitive adhesive material, may be inserted into a conventional cap-retaining means illustrated in broken lines 27 of FIG. 4 for positioning the cap in the path of the hammer 26 to detonate the charge. The cap 19 may be optionally stuck to the striking face of the hammer if desired, for firing thereof against the anvil.

Referring to FIG. 5, an anvil 3.1 is illustrated in the form of a simulated cartridge. The cartridge includes a shell 32 provided with a flat end 33 to which a cap unit 19, having pressure-sensitive adhesive material 13 secured to the face 21, as previously described, may be adhered for detonation of the charge 14 thereof as by a hammer, similar to the hammer 26 of FIG. 4.

As illustrated in FIG. 6, cap units 19, having pressuresensitive adhesive material 13 secured thereto, .may be spaced on a strip 34 of paper, or other suitable material, for storage of the caps 19 thereon or optionally for feeding of the caps 19 in any predetermined spaced relationship over an anvil of the rotating or other type.

To facilitate removal of the caps 19 from the structure 10, the

sheet

11 or 12 which does not have the pressuresensitive adhesive material secured thereto preferably includes a glossy surface adjacent the juxtaposed sheet to prevent excessive adherence thereto.

While I have herein shown and described my invention in what I have conceived to be the most practical and preferred embodiments, it is recognized that departures may be made therefrom within the scope of my invention, which is not to be limited to the details disclosed herein but is to be accorded the full scope of the claims so as to embrace any and all equivalent devices and methods.
