Specification of Letters Patent.

Patented May 27, 1919.

Application led December 1,1, 1917. Serial No. 206,634..A

To all whom t may concern:

Be it known that I, CLARENCE JANES, a citizen of the United States, residing at Oneida, in the county ot' Madison and State of New York, have invented new and useful IImprovements in Projectiles, of which the following is a specification.

This invention relates to projectiles of the type designed to be charged with high eX- plosives,.and the object is to provide means for preventing the premature tiring of the charge.

.A further object is to provide, a magazine adapted to maintain a stationary position, so far as rotary movement is concerned, during the ight of the projectile, whereby the shock incident to the sudden rotation of the body portion of the shell, imparted b v the rifling of the gun, shall be avoided, and the charge maintained intact until set .otl by the operation of the firing mechanism.

A, still further object is to provide in a. shell having a body portion `comprising an outer casing, a separate nose portion and a separate breech portion, means for mounting a magazine independently of allofsaid elements, 'said breech portion and nose portionbeing connected by a longitudinal member coincident with the main aXis of the shell and permitting' rotation independently of the magazine.

In the accompanying drawings:

/Figure 1 is a view in elevation with parts iown in ldotted lines.

y Fig. 2 is a view in longitudinal section.

' Fig. 3 is arear end view.

Fig. 4 is a section on the line 4-4 of Fig. 2,.

Fig. 5` is a section on the line 5 5 of Fig. 2. y

Fig, 6 is a sect-ion on line 6-6 of Fig. 2.

Fig. 7 is a section through the tiring device.

Figs. 8 and 9 are details inlel'evation of another form of charging device for the magazine.

The body portion of the shell includes an outer casing designated 10 havingl connection at 12 with a nose portion 14, and having connection at 15 with a breech portion or base portion 16. A shaft 1S extends longitudinally of the shell and coincident with the main axis thereof, the forward endof. the shaft A*beingl mounted Within the nose portion and tie rear end thereof mounted in the base portion.

being The structure including the casing 10, the shaft, the nose portion and base portion constitutes the rotary unit, this unit also inl yfor spacing the latter and the magazine from the nose portion mounted as speciiied below. This spacing function serves to retain the magazine .in such position that the firing device carried by the magazine is normally out of contact with the nose portion and therefore iii inoperative position (the firing pin por se being mounted as shown in Fig. 7). The sleeve 2O is provided with a longitudinal slot 22 engaged by a pin or the like 23 carried by theI shaft and preventing the rotary movement of the sleeve with reterence to the shaft.

The magazine 25 is provided with end portions 2G and 27 having cent-rally located vapertures therein within which is-mounted a sleeve 28 forming a rigid element of the magazine and permitting the entire magazine to rotate with reference to the inner` sleeve 20. llVh'ile reference is made to the rotation ot the magazine with reference to tlieshaft and theinner sleeve, for conven' ience, it is of course understood that the body portion proper rotates independently of the magazine during flight.

Ball bearings are provided to permit of the rotation of the body portion with 'the minimum degree of friction, the race inembers for these bearings being designated respectively 31 and 32, the members 3l being` carried ,rigidly by the inner sleeve 2O and the members 32 by the end portions of the magazine. The seriesjof balls within the bearings is shown at 34: at each end of the magazine. i

End portion. 2G of the magazine is provided with a firing device including a resiliently mounted tiring pin 35 operating within a tubular member 3G secured in position by a lock nut 37.V A tubular flanged member 3S surrounds one en d ot the tubular member first named and serves as a spacing device between the adjacent end portion of the iifiagazine aud the nose portion of the shell. The tubular member 36 is provided Vwith laterally extending openings or ports communicating with the main bore Of- -in Fig. s.

said tubular member, and a screw 39 retains the'percussion cap in position to receive the im'pact of the firing pin.

The breech portion 16 is provided with a bore 45 terminating at the outer end of said breech portion in an enlarged bore or recess 46 adaptedto be closed by a screw plug 47. A tubular member 48 is mounted Within'the bore, is movable longitudinally therein and constitutes a filling tube. The enlarged end 50 extends within a recess 5l of the screw plug, and the opposite end ofthe filling tube is adapted to telescope with reference to a tube 53 extending through end member 27 of vthe magazine. The filling tube and the tube 53 are in engagement, only durin the filling operation, being normally hel out of engagement by.a spring 55. After filling the magazine, the' t'ube 53 is closed by introducing any suitable material in condition through the filling tube. y.

When the projectile is rotated upon 'engagenkient with the rifling ofthe gun, the body portion, portion and base, the shaft and the inner sleeve, are rotated independently of theA magazine, the latter acting in a measure as a balanced and stationary object havingsufficient inertia to resist rotation, such as Would ordinarily be imparted by the rotation of the body portion.

In Figs. 8 and 9 I have shown a 'form of filling device comprising a tubular member 48,"having Va flange 50 and having its 0E- posite end tapered in order that it may t between the members-60 and 61 pivoted at 62 and normally retained in closed position by means of a U-shaped spring 63 mounted atA 64.

The tapered portion of the filling tube is l forced between pivoted members 60, 61, and

the tube may then enter the fillingaperture This aperture is closed upon the Withdrawal of the tube and when elements 60V 61 assume their normal position, illustrated What is-claimed is:

1. In a projectile, body ortion, a nose magazine mounted Iin t supportin latter to 'ave a movement independent of the magazine, a firing device connected with a casing including a said magazine and operated by impact WithA the nose of the projectile, and 'means for charging the magazine, comprisinga longitudinallly movable tube mounted in the. base.

2. In 'a projectile, a casing including a body portion, avnose ortion and a breech portion. a shaft exten ing through the body including casingv 10 thenose portion andbase, a e casing, meansfor' the caslng for permltti-ng'the sleeve and shaft being rotatable with refer` ence to the magazine and the sleeve. and magazine being slidable 'longitudinally on thel shaft, and means operable upon such longitudinal movement for firing a charge.

4. In a projectilea casin a shaft cxtending longitudinally thereov a sleeve havportion respecing a limited. movement longitudinally of the shaftand non-rotatable' with reference thereto, resilient means carried by the shaft and controlling the longitudinal movement of the sleeve, and a magazine inclosing said shaft and sleeve, the shaft and sleeve being rotatablewith reference to the magazine.

5. 'In a projectile,'a casing, a shaft cx' tending axially thereof, a sleeve surroundin'g said shaft and non-rotatable with reference thereto, an' outer sleeve surrounding the sleeve first named, l'a cylinder for containing a charge, end Walls for the cylinder serving to rigidly mount the outer sleeve, permltting the casing, shaft and inner sleeve to rotate' with reference t'o the outer sleeve 'i and cylinder. j f 6. In a'projectilc, a-magazine, tion' rotatable independently of y zine, and a firing devicegoperated by the longitudinal movement of the magazine Within the body portion.

casing, a nose portion, means permitting the rotary and longitudinal movement of the casing and nose portionwith reference to the magazine, and means whereby the charge may be fired as lthe result of said longitudinal movement. l 8. In a projectile, ay casing including a base, a magazine Within the casing,i and with reference -to which the. casing is rotatable, the .magazine being movable longitudinally in the casing, and a tube for filling the magazine' and movable longitudinally through the base. l

In testimony whereof I afiix my signature.
