This invention relates to improvements in' shells or other projectiles for guns.
The object of the invention is to provide a projectile for guns whereby the friction'between the sides of the projectile and the inside of the gun-barrel will be reduced to a minimum.
A further object is to construct a projectile of this character which will be simple in construction and may be inexpensively produced.
With these and other objects in view the invention consists of certain novel features of construction, combination, and arrangement of parts, as will be more fully described, and particularly pointed out in the appended claims.
In the accompanying drawings, Figure 1 is a side elevation of a projectile constructed in accordance with the invention. Fig. 2 is a longitudinal sectional view, and Fig. 3 is a vertical cross-sectional view of the same.
Referring more particularly to the drawings, 1 denotes a projectile which may be in the form of a shell or in the form of a solid shot or bullet. As shown in the drawings, the projectile is in the form of a solid shot having an elongated slightly-tapering body portion formed at one end with a point 2 and at its other end an annular shoulder or flange 2. In the sides of the shot are formed a series of longitudinal radially disposed grooves or channels 3, which extend from near the inner flanged end of the shot to the forward end of the tapered portion of the same. The grooves or channels 3 are dovetail shape in cross-section, and in each of the same is arranged a strip or block 4 of wood or other suitable material. The blocks 4 are of dovetail shape in cross-section and are adapted to be slipped into the grooves or channels 3 from the forward or pointed end of the bullet. The thickness of the strips or blocks 4 is somewhat greater than the depth of the grooves 3, thereby causing the outer sides of the blocks to project radially from the sides of the shot to the height of the collar or flange 2.
The forward ends of the blocks are beveled off to correspond with the pointed end of the shot.
In the drawings are shown four of the blocks 4, arranged at diametrically opposite points around the'shot. This number, may, however, be increased or diminished, as desired.
When the shot is placed in the gun-barrel, the blocks engage the inner sides of the same, thereby preventing the body of the shot from engaging the inner side of the gun-barrel, except at its rear flanged or shouldered end, thus greatly diminishing the friction between the shot and the inner wall of the gunbarrel, and in order to further eliminate such friction the blocks are saturated with oil or other suitable lubricant. The flange or shoulder 2 is necessary on the inner end of the shot to overcome the windage between the shot and the inner wall of the gun-barrel.
While wood has been particularly described as the material of which the blocks are composed, it is obvious that I may form the same of any suitable porous material which will absorb oil or other lubricant.
From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explantion.
Various changes in the form, proportion, and the minordetails of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. A projectile consisting of a body portion pointed at one end and provided with longitudinally disposed dovetailed grooves formed circumferentially in the sides of said body portion and extending from near one end of the body portion to the taper of the point, and wooden strips of dovetail form inserted in said grooves and having applied thereto a lubricating material, said wooden strips extending beyond the surface of the body portion, substantially as described.
2. A projectile consisting of a slightly-tapered body portion, pointed at one end and provided with an annular flange or shoulder formed on the rear or inner end of the same, longitudinally-disposed dovetail grooves extending from the shoulder to the point, and
oiled Wooden blocks or strips arranged in said my hand in presence of two subscribing Witgrooves, the inner ends of said blocks bearing nesses.
eminst said shoulder and the outer ends bein 1 tgpered to lie flush with the surface of th: HOMER BEALE point of the projectile, substantially as de- Witnesses:
