NELSON W. DINGWALL AND CLIFFORD M. BUDD, OF NEW YORK, N. Y.

ADAPTER AND BOOSTER CASING FOR SHELLS.

Specification of Letters Patent.

Patented Mar. 4, 1919.

Application filed July 26, 1918. Serial No. 246,897.

To all whom it may concern:

Be it known that we, NELSON W. DING- WALL and CLIFFORD M. Bonn, citizens of the United States, residing at New York, in the county of New York and State of New York, have invented new and useful Improvements in Adapter and Booster Casings for Shells, of which the following is a specification.

This invention relates to an adapter and booster casing for shells and projectiles, and has as its purpose to provide a structure which is greatly simplified so that the cost of manufacture is very substantially reduced.

In accordance with our invention, the adapter head and booster caslng are made by drawing a sheet of metal into substantially final form thereby doing away with the time and expense of carrying out various operations in machining the parts from bar stock or forgings and joining the parts together.

Since the adapter head and booster casing are integral, no joints are provided therebetween through which gas might leak from the shell into the interior of the booster casing, and this is of particular advantage, as it has been found that where the adapter and booster casing are made separately and then joined together, the gas of a gas shell will leak through the joint into the adapter head and then pass from the head and constitute a source of danger to persons handling the shell.

In the accompanying drawings, we have illustrated several embodiments of our in vention, but it is to be understood that the present disclosure is illustrative only and is not restrictive of our invention and that it is susceptible of various changes which would be within the spirit of our conception without departing from the scope of the appended claims.

In said drawing,

Figure 1 is a longitudinal sectional view of one embodiment of our improved adapter and booster casing.

Fig. 2 is a sectional view taken on a line 2-2 of Fig. 1.

Fig. 3 is a sectional view on an enlarged scale showing the manner of connecting the fuse socket to the fuse socket holder.

Figs. 4, 5 and 6 are views similar to Fig. 1, but show different embodiments of our invention.

Fig. 7 is a view similar to Fig. 1 but illustrates another form of our invention.

Fig. 8 is a perspective view of certain parts which may be used in the adapter head and easing shown in Fig. 7.

Fig. 9 is a longitudinal sectional view of still another form of our invention.

In the drawings, like reference characters designate like parts in the several views. Referring to that embodiment of our invention disclosed in Figs. 1 to 3, inclusive, 1O designates the booster casing having a chamber which receives the booster charge and 11 designates the adapter head. The adapter head and the booster casing are integral With each other and are preferably formed from a single sheet of metal drawn to the shape illustrated, so that the cost of manufacture is relatively low, and no joints between the booster casing and the adapter are presented through which gas may pass. The head 11 is of greater diameter than the booster casing and the openingthrough the head 11 gradually increases in diameter tothreaded for a portion of its length, as at 14, so that it may be screwed into the threaded opening in the nose of the projectile 15 which, for illustrative purposes, is shown in dotted lines. The threaded portion 14, preferably, will be tapered in the event the adapter is to be used in connection with a shell containing gas, but it may be straight, if desired. In the outer end of the adapter head 11 are recesses 16 adapted to receive a spanner wrench when the head 11 is to be screwed into place. i

Fitting within the adapter head 11 is the bushing .17, which takes the place of the usual fuse bushing and fuse socket holder, which parts are now generally made in two pieces. The bushing 17, which is circular in cross-section, tapers inwardly slightly toward its inner end so that it is frusto conical and corresponds in slope to the opening in the adjuster head 11. Adjacent the lower end of the bushing 17 the external surface is reduced and abruptly inclined as at 18. The inclination of the surface 18 is more pronounced than the shoulder 13 of the portion 12 so that there is suflicient clearance 'ment. The-inner endof the bushing l7is bent radially inward to fo rm an internal lip on flange 19, to which is connected :the "fuse socket 20 adapted toreceive the detonati'ng charge." 1. The fuse socket 20 is made of sheet' netal socket is' a; flange 21 formed by spinning thewall of thesoeketioutwardly so as to fold the'spun out: portion uponitseli To secure. the fuse socket in place on the bush therebetween td permit thebushing" 17 to be tightly wedged in place inthefadapter' head without bringing these surfaces into engagepressed to the form of a thimble. Spaced a slight J distance from. the open end of the ing 17, r the open ,end ofthe socket isinse'rted' within the lip. 19' until-the jfla nge, 21 engages the lower 'surfaceof thelip and i 7 then the metal about the open end "of the socketis bent outwardly to forma flange 22 lwhieh'engages'the upper surface f'the It will be seen the above description of the embodiment of the invention shown 2 in Figs. 1 to 3 thatthe humber of separate parts is reduced to a minimum and each I of these parts requiresbut a relatiyelyjfe'w operations in, their manufacture. P The parts may be readily assembled, it being only necesd t pr per, pe sing l7? hasia body .pQrti0n-23 which-tapers 4 so as to fit" snugly; Within the head 11 and" c or ally and inwardly toiprov de a fiange19,' to which th :fujsesocket920 is secured.

thatv the lower .end fof the V threaded so as to explosive and thenthe washer in somerespects,

and a socket carrying adapter shown in' Fig. 1, and the bushing 17 is similar in construction to that shown in Fig. '43 In F ig. 5, parts of the booster casing and adapter head are designated by thesanie numerals as those employed to indicate likeparts in Fig. 1, and the parts of the bushing 17 are designated by the same numerals as the bushing in Fig. 4.

i In the embodiment shown in Fig. 6 the head has a tapering body portion 11 and a skirt 25 surrounding the portion 11 and the skirt is externally threaded as at 26'so that the. adapter may be screwed into. the

threaded opening in the nose of the bullet.

The'bushing 17 is similar to the. bushing 17", as shown in thetwonext preceding embodiments, but in this instance the tapering opening of the head 11" and the bushing are provided with complementary screwthreads 27,- sothat the bushing is screwed into] the head." The threads 27 terminate short ofthe l'owerend of the bushingso bushing, has a wedgelike fit in'theadapter head. n i In that embodiment of ourflinvention shown in 7, the booster easing 10 and the adapter head 11 are formed: fromla single sheet of metal drawn to the shape illustrated, but in this instance, there isasharp internal shoulder 28; betweenthe head and casing," and thejope'ning through the, head is not tapered, but 7 is' of like diameter throughout itslength, The opening through the head,-at its outer end, is "threaded as at I 29,fso asto receive in threaded engagement a bushing 30 which. carries a sleeve31, which sleev'e, inthis embodiment, is integral with the bushing. The bushing 30 isinternally indotted lines. V.

vided. The shape of the socket carrying member 32 is similar to the lower portion of the bushing 17 of Fig. 1. It is, of course, evident that in Fig. 1 the bushing 17 may be divided into three parts, corresponding to

parts

30, 31, and 32 of Fig. 9.

It will be noted that in each embodiment of our invention the adapter head and booster casing are made integral with each other and are preferably formed by drawing a sheet of metal to the desired shape.

What we claim is:

1. In combinatioma booster casing, and an adapter head having a ta ering opening, said booster casing and hea being formed by drawing a single sheet of metal to the proper shape.

2. In combination, a booster casing and an adapter head formed integrally with each other, said head having an interior tapering surface, a bushing for receiving a fuse nipple resting on said surface within said head, and a fuse socket carried by said bushing.

3. In combination, a booster casing, an adapter head having a tapering opening, and a tapering bushing in said opening.

4. In combination, a booster casing having an integral tapering portion at its open end, and a tapering bushing in and making wedging contact with said tapering portion.
