Definitions
- wads have been manufactured in the past of various materials such as paper, cotton, wool and plastic. Such wads are ordinarily made in specific sizes corresponding tothe main shell sizes, 10, 12, 16, .410 and 20 gauge which cover a bore diameter size range from 0.775 inch to 0.410 inch.
- Another object is to provide an improved wad which in addition to accomplishing the foregoing objects provides for improved discharge of the shot pellets with a minimum of scattering.
- the present invention provides an improved wad consisting of a combination of two principal members, an outer member and an inner member adapted to be arranged one inside the other; the construction of the said members is such that depending on the position of the inner member inside the outer member, the total wad can be made to adapt to all principal kinds of shotgun shells as aforesaid, high and low inner base shells. At the same time the wad can be made in all diameters of ordinarily-used shells in addition to providing other advantages.

- FIGURE 2 illustrates the elements of wad 6 in some detail as seen in longitudinal medial crosssection, and as will be seen there are two main components, an outer hollow element rather resembling a tumbler with a thick bottom, which will be referred to as outer cup 10. Inside the latter element is a component somewhat similar in appearance to outer cup 10 but of lesser length and of smaller size so that it fits inside outer cup 10, denoted herein as inner cup 11.
- Outer cup 10 has a base of which the extreme lower surface is particularly shown in FIGURES 4 and 6 denoted herein as end 12.
- End 12 of outer cup 10 has a relatively deep annular groove running therearound fairly close to its periphery denoted by 13.
- the effect of groove 13 is to provide a pressure skirt whereby the exploding powder charge adjacent end 12 creates gas which enters groove 13 and pushes the extremities outwardly so as to cause wad 6 to grip tightly upon the inside of wall 4 of shotgun shell 1.
- a gripping effect of the kind described is known in the firearm art but chiefly in relation to projectiles-the so-called Mini effect whereby a projectile is caused to expand outwardly so as to grip tightly upon the inside of the bore of a firearm during discharge.
- End 12 is thin in cross-section except in the region of groove 13 and where strengthening ribs are provided at 14 seen particularly in FIGURE 5, the latter for the obvious purpose of making the wad 6 as strong as possible with a minimum of material.
- a cylindrical flange denoted by 15 of typical length approximately twice the diameter of outer cup 10.
- the external surface of flange 15 is cylindrical in the sense that it is of uniform diameter from one end to the other insofar as this can be accomplished by standard manufacturing methods.
- the inside of flange is not, however, of uniform inside diameter but the inside diameter increases from left to right as seen in FIGURE 2 to provide a distinct thickness taper for flange 15. That is, the flange 15 tapers in thickness from left to right as seen in FIGURE 2 becoming thinner in that direction.
- a taper of approximately 3 along the length of flange 15 is typically used.
- inner cup 11 will be moved within outer cup 10 and a consequence of this along with the taper just referred to is that flange 15 of outer cup 10 caused to expand, and this assists in accommodating whatever internal diameter of shotgun shell may be used.
- flexibility of the flange 15 is such that the tightly packed shot pellet 7 aids in such expansion.
- flange 15 shall have slots such as are denoted by 16 running approximately half the length of flange 15. Four slots arranged in quadrature as particularly shown in FIGURE have been found to be a satisfactory arrangement.
- the inner cup 11 consists of a cylindrical flange 20 which is of uniform outside diameter. Inside cylindrical flange 20 is wall 21 closing the cylinder formed by cylindrical flange 20 at a position approximately a third of the distance along the length of cylindrical flange 20, as seen from the bottom of FIG- URE 7.
- inner cup 11 While the outside of inner cup 11 is of uniform diameter, the inside is not necessarily uniform, and from the standpoint of moulding inner cup 11, it is preferable if the inside surfaces shown at 22 and 23 be slightly tapered. However, this feature is not of special importance and all that is required is substantial uniform inside diameter and a relatively thin cylindrical flange 20.
- Wall 21 is perforated by a small centrally-located hole at 25, the purpose of which is to allow air to escape when two units are put together.
- Wall 21 has rib members 24 somewhat similar to ribs 14 of outer cup 10 already referred to.

WAD FOR SHOTGUN SHELLS Filed March 9, 1967 Jun-m?! INVENIOR HENRY G. R'MPEL www, M, M
United States Patent 3,420,178 WAD FOR SHOTGUN SHELLS Henry George Rempel, 4207 Fraser St., Vancouver 10, British Columbia, Canada Filed Mar. 9, 1967, Ser. No. 621,961 U.S. Cl. 102-95 7 Claims Int. Cl. F42b 7/08 ABSTRACT OF THE DISCLOSURE This application relates to a new and improved wad for shotgun shells. As is well known, shoutgun shells require wadding of some sort to keep the powder in place and ensure that when the shell is fired, the explosion of the powder will be transmitted properly to the shot pellets and will force the latter forward toward the muzzle for a proper discharge of the shotgun.
Many kinds of wads have been manufactured in the past of various materials such as paper, cotton, wool and plastic. Such wads are ordinarily made in specific sizes corresponding tothe main shell sizes, 10, 12, 16, .410 and 20 gauge which cover a bore diameter size range from 0.775 inch to 0.410 inch.
It is a principal object of the present invention to provide a universal wad in the sense that it may be used with all principal types of shotgun shells, high inner base shells and low inner base shells and all variations in between.
Another object is to provide an improved wad which in addition to accomplishing the foregoing objects provides for improved discharge of the shot pellets with a minimum of scattering.
Other objects and advantages will be apparent from a reading of the present specification and the appended claims, and will be apparent to a person familiar with firearms and ammunition of the kind under discussion.
Although the definition of the present invention is to be'taken from a reading of the appended claims, it may be stated that the present invention provides an improved wad consisting of a combination of two principal members, an outer member and an inner member adapted to be arranged one inside the other; the construction of the said members is such that depending on the position of the inner member inside the outer member, the total wad can be made to adapt to all principal kinds of shotgun shells as aforesaid, high and low inner base shells. At the same time the wad can be made in all diameters of ordinarily-used shells in addition to providing other advantages.
The present invention will now be described by way of example with reference to the accompanying drawings.
In the accompanying drawings,
FIGURE 1 shows a cross-sectional view of a shotgun shell in which a wad made in accordance with the present invention has been fitted, the shotgun shell shown being, apart from the wad, quite conventional;
FIGURE 2 shows a cross-sectional view of the wad by itself;
FIGURE 3 shows a further cross-sectional view of the wad in which there is a juxtaposition of the two principal elements as compared with FIGURE 2;
FIGURE 4 shows a partly cross-sectional view of the outer part of the wad;
FIGURE 5 shows a top plan view of that part of the wad as illustrated in FIGURE 4 looking downwardly upon FIGURE 4;
FIGURE 6 shows a bottom or reverse plan view of that part of the wad illustrated in FIGURE 4 looking upwardly toward FIGURE 4;
FIGURES 7, 8 and 9 are the same kind of views as FIGURES 4, 5 and 6 respectively, only they illustrate the inner part of the wad;
FIGURE 7 shows a partly cross-sectional view of the inner part of the wad;
FIGURE 8 shows a top plan view of that part of the wad as illustrated in FIGURE 7 looking downwardly upon FIGURE 7;
FIGURE 9 shows a bottom or reverseplan view of that part of the wad illustrated in FIGURE 7 looking upwardly toward FIGURE 7;
FIGURE 10 shows a somewhat exaggerated crosssectional view of the wad to illustrate the manner in which the wad is deformed so as to be adaptable to diflerent shotgun shell diameters.
Referring now to the accompanying drawings wherein the same reference numerals denote like parts in all figures, and referring first to FIGURE 1, a shotgun shell of conventional construction, apart from the wad of the present invention is shown generally at 1. Shotgun shell 1 has a conventional base 2, which in this example is shown with a low inner base. The priming cap 3 is in the center of base 2. The side wall is at 4 of the usual hollow cylindrical construction. The propellant charge is at 5 and is typically smokless powder. The wad in accordance with this invention is shown at 6 and will be further described below. The shot pellets denoted as 7 are kept in place by the closed end of the shell denoted as 8. As stated previously, every element described up to the present time, except for wad -6 are perfectly conventional.
The construction of the wad 6 can be understood with particular reference to the remainder of the drawings, FIGURES 2-10. FIGURE 2 illustrates the elements of wad 6 in some detail as seen in longitudinal medial crosssection, and as will be seen there are two main components, an outer hollow element rather resembling a tumbler with a thick bottom, which will be referred to as outer cup 10. Inside the latter element is a component somewhat similar in appearance to outer cup 10 but of lesser length and of smaller size so that it fits inside outer cup 10, denoted herein as inner cup 11.
Extending outwardly of end 12 of outer cup 10 on the same side of end 12 as ribs 14 is a cylindrical flange denoted by 15 of typical length approximately twice the diameter of outer cup 10. The external surface of flange 15 is cylindrical in the sense that it is of uniform diameter from one end to the other insofar as this can be accomplished by standard manufacturing methods. The inside of flange is not, however, of uniform inside diameter but the inside diameter increases from left to right as seen in FIGURE 2 to provide a distinct thickness taper for flange 15. That is, the flange 15 tapers in thickness from left to right as seen in FIGURE 2 becoming thinner in that direction. A taper of approximately 3 along the length of flange 15 is typically used.
It is contemplated that inner cup 11 will be moved within outer cup 10 and a consequence of this along with the taper just referred to is that flange 15 of outer cup 10 caused to expand, and this assists in accommodating whatever internal diameter of shotgun shell may be used. In addition, the flexibility of the flange 15 is such that the tightly packed shot pellet 7 aids in such expansion. To liberate the shot to be expelled in a body from the wad it has been found desirable that flange 15 shall have slots such as are denoted by 16 running approximately half the length of flange 15. Four slots arranged in quadrature as particularly shown in FIGURE have been found to be a satisfactory arrangement.
Although exact dimensions are subject to variation and keeping in mind that the purpose of the device described controls to a large extent the size, it has been found satisfactory if the dimensions of outer cup 10 are as follows:
Inches Overall length 1.375 Overall width 0.720 Inside diameter of flange at open end 0.670 Inside diameter of flange 15 at closed end 0.650 Length of slot 16 0.625 Width of slot 16 Referring now to inner cup 11 particularly shown in FIGURES 7, 8 and 9, the inner cup 11 consists of a cylindrical flange 20 which is of uniform outside diameter. Inside cylindrical flange 20 is wall 21 closing the cylinder formed by cylindrical flange 20 at a position approximately a third of the distance along the length of cylindrical flange 20, as seen from the bottom of FIG- URE 7.
While the outside of inner cup 11 is of uniform diameter, the inside is not necessarily uniform, and from the standpoint of moulding inner cup 11, it is preferable if the inside surfaces shown at 22 and 23 be slightly tapered. However, this feature is not of special importance and all that is required is substantial uniform inside diameter and a relatively thin cylindrical flange 20.
Wall 21 is perforated by a small centrally-located hole at 25, the purpose of which is to allow air to escape when two units are put together. Wall 21 has rib members 24 somewhat similar to ribs 14 of outer cup 10 already referred to.
As in the case of outer cup 10, dimensions are subject to variation. By way of example an inner cup 10 to fit the dimensions set forth above for outer cup 10 have been found satisfactory:
Inches Overall length 0.705 Overall width 0.672
Distance from upper side of inner cup 11, as seen in FIGURE 7 to upper edge at extreme top as seen in FIGURE 7 0.450 Size of hole 25 FIGURES 2 and 3 show how outer cup 10 and inner cup 11 fit together. FIGURE 3 is very similar to FIG- URE 2 except that inner cup 11 is reversed in longitudinal position. FIGURE 2 represents the relative positions of outer cup 10 and inner cup 11 when wad 6 is to be used with high inner base shells, while FIGURE 3 represents the relative positions of outer cup 10 and inner cup 11 for use with low inner base shells. FIGURE 1 illustrates a high inner base shell, and as will be seen the wad 6 is in FIGURE 1 as shown in FIGURE 2. The object is to have wall 21 at roughly the same distance from either end 'of the shell regardless of whether the shell is high base or low base and it will be seen that this is accomplished by the present invention.
The gripping action of wad 6 is important in either position. It will be obvious that having regard to the pressure of shot 7 as well as the taper of the inside diameter of outer cup 10, outer cup 10 can be caused to bulge and have its outside diameter increased in a region of outer cup 10 depending on the position of inner cup 11.
The distortion of outer cup 10 contributing to the gripping action of wad 6 is shown in exaggerated form in FIGURE 10 wherein outer cup 10 is now represented by cup and wherein the taper of the inside is exaggerated. The inner cup 11 is now shown as inner cup 111. The effect of the pressure of shot 7 should not be overlooked in achieving the gripping action referred to.
As may be seen, as inner cup 111 is moving in a downward direction as seen in FIGURE 10, outer cup 110 is caused to bulge as at 113 thereby increasing. the outside diameter of the wad 6, and the effect is similar whether outer cup 10 and inner cup 11 are in the relative positions shown in FIGURE 2 or 3.
The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:
1. A wad for shotgun shells comprising an outer cup member and an inner cup member, the outer cup member comprising a first hollow cylinder having internal and external cylindrical surfaces and a base closing one end of said cylinder, the inner cup member comprising a second hollow cylinder having internal and external cylindrical surfaces and a partition member disposed internally of said second member at a position closer to one end of said second cylinder than to the opposite end thereof, whereby said second cylinder is divided into two chambers of unequal volume, the relative dimensions of the internal cylindrical surface of said outer cup member and the external cylindrical surface of said inner cup member being such that the two said surfaces have a sliding fit therebetween, whereby the inner cup member may be assembled in said outer cup member with either end of the inner cup member adjacent the base of the outer member providing wads of alternative volumes.
