Specification of Letters latent, Patented 10,
v fA pplicati on filed December 9, 19 14. ammo. 876,236.
Be it known lthatlI, Josiarn T'HoiaPsoN PARKER, a citizen of the United States, re-
- siding at'l/Vashington, District, of Columbia,
have invented certain new and useful Improvements in Projectiles-for Ordnance, of which the following is a specification.
The object of this invention is to so construct the projectile that with a given weightof metal and a. given charge,it can be fired. to a greater distance, may be fired-more 'ac-. curately and will have a greater penetrata, ing power. the latter being due to its having less atmospheric resistance in. its. flight through the air, as'more fully hereinafter; set forth.- r
In the drawings annexed, Figure 1 is a side elevation of a projectile as itappears in flight; Fig. 2 a sectional elevation ofa projectile as it appears before firing; and Fig. 3 a plan view of the plug detached. i
' The projectile body 1 is of the usual shape G'XCQPtillilt This provided with a hole or passage 2, circular'in cross-section and extending centrally from the point of the projectile to the base thereof. Atfixed tothe base is'a circular metal plug'*3 having a tapered portion 5 which lies against the base of the projectile around the passage 2,,t'he. edge of this tapered portion terminating short of the edge of the projectile. plug is provided with a central lug; which"? fits in the passage 2, and the bodyof the plug is thickened centrally. The plug is held in place against the base of the projec tile by a thin metal cap (3 which is shaped to fit the face of the plug and has its outer edge bent to form an annular flange ,8 which hugs the base-end of the projectile, this flange being beaded to fit into a groove 7 formed around the projectile near its base. Around the flange 8 is fitted a metal baiid 9. \Vhen the projectile is fired, the pressure of air through the passage against the plug and against the band 9 will be sufiic ient to throw ofl' the plug, the cap and the band, and thus leave the projectile free from these devices during its flight. It will be understood that the parts 8 and 9 will clamp the plug to the projectilewith sufficient firmness to permit the projectile to be handled and transported without dislodging the pa rts,but not with sufiicient firmness to pretion of the The vent the-air 'ressure caused by the travlij .of the projectile from. throwingitheseparts oif the projectile as soon as the projectile issues from the bore of the gun. The parts 8 and 9 will perform the'additional func tion of a packing for the shell, and the purpose in centrally thickening the plug is to enable t to withstand the pressure of explosion at the point where the greatest strain,
will come, namely, coincident with the bore 52. j The lug 4 assists in holding the plug in position during handling andtransporta- I device and strengthen the plug centrally thereof. Byemploying a thin metal cap to fasten the plug 1n position and having the outer edge of this cap hug .the base end of the projectile, it will be -sen that it will be a simple matter toobtain the desired degree of clampcases theannulus 9 may be dispensed with .-ent,irely as is obvious. It will be seen that projectile -by"means of. screws '-'l0 or other fastening means.
.I c1a1m I" A jprojectile having a,central channel ext'ending through it, a plug applied to its rear end and provided with a projection enteringsaid channel, the plug being thickened also tends to" .ing, action" upon the" projectile. In some I centrally, a cap embracing and inclosingtherearpface of thel gplu'gand having its annular edge embracing the rear end of the projectile and interlocked therewith, and vanannular bandfitting over the said embracing edge of the capl 2. A projectilegiprovided with a longitudinal central channel and an external annular groove near itsfrear end, a plug fitted against" the rear end of the projectile, a cap inclosing the plug and the rear' end of the projectile. the cap being provided with an an nular bead fitting in the aforesaid groove, and an annular band fitted around the beaded edge of the cap.
3. A projectile provided with a central longitudinal passage through it and also with an external annular groove near its base end, a plug covering the rear end.of
said pa's sage; and a thin' metal cap covering 'afiixed my si'ghatu're in the-presence of two and embracing the plug and having its outer Witnesses.
edge flan ed this fian e embracin the base j end of th? p cojectile 231d bent S6 is to enter JOSEPH THUMBS-ON PARKER and interlock with the aforesaid. annular Witnesses: v g'roove in the projectile. \VALTER B. B RROW,
