To all whom, it may concern:

Be it known that TAPLEY W. YOUNG, a

I citizen of the United States, residing at \Vash agency provided to arrest the concussion imparted to ington, in the District of Columbia, have in-j vented certain new and useful Improvements in Dynamite Shells; and I do hereby declare the following to be a full, clear, and exact dcsc'ript-iou of the invention, such as will enable others skilled in the art to which it appertai'ns to make and use the same. My invention relates to projectiles of the class designed to contain a charge of highlyexplosive compound, such as dynamite, and

the metallic shell by the initial charge before it hasibeen communicated to the dynamite, else there will be great'dang'er of an explosion of the latter before theshell is ejected from the cannon.

To provide a vessel forv containing the explosive compound which will not be subject to the dangerous effects of undue concussion resulting from theexplosion of the charge of gunpowder behind the shell in which the vessel is placed is the objectotmy invention, which consists-in the novel construction and arrangement of parts, which will first be fully described in connection with the accompanying drawing, and-then clearly pointed outin theclaims. a i

In thedrawing, which is a vertical section of a shell containing my improvement, A represents an ordinary metallic shell. v

Bis the vessel for containing the explosive compound, preferably bottle-shaped, as shown.

0 represents the outer casing of the vessel B, the said casing being of a size and shape to snugly fit the bore .of the shell. j

D D represent annular rims connecting vessel'B and easing 0, being preferably formed integral with those parts, and through these rims, at suitable intervals, are perforations d, for a purpose which will formed,- integral with one of the annular rims, and is made somewhat thicker than the rim, as seen in the drawing, so as to, offer greater resistance to diaphragm E. 3

The space between the bottom of the vessel and the bottom of thebore-of the shellis (iii vided. by a diaphragm, E, joined to the casing, thus leaving an air-cushion, F, in the bottom of the shelL- r The vessel, casing, rims, and diaphragm are In fitting the shell for use these parts can be when they will at once expand and assume their proper forms.

The mouth of .the shell and also the inouth all made'of elastic material, such as rubben the air driven against it by the dcflection'of. I

compressed sufiiciently to enter at the mouth,

of the vessel are closed by a metal screw-,

plug, A, the lowerend of which is considera blyv reduced in diameter, and over'this reduced portion is fitted a rubber stopper, G. The flange b around the mouth of thevessel takes into a recess, a, in the top of the shell, over which is placed an annular ring,"H, flush with the top of the shell,'for securing thefvessel at that point.

Rearwardly inclined perforations I are formed through the uppcrs'portion of the shell and easing, as show perforations preferably corresponding in num her with the perforationsin each of the rims D.

The 'desired quantity u in the-drawingfthese.

of dynamite or other I like'explosive compound having'be 'p e presently appear. 5o The bottom of vessel B is charge of powder. When the explosion of the powder takes place, the concussion innparted to the bottom of the shell causes an impactof the airin the cushion against diaphragm E, which, beingelast-ic, is thereby deflected in a manner shown in dotted line.

This sudden deflection drive the air above of the diaphragm will it outwardly and 11pwardly through the'perforations d outside and around the vessel 0, when-it will escape from not. be filled full, the compound would of course have motion within it, and therefore,

theshell through perforations '1. Thus there .will be no such impact on the vessel at any,

explosion of its contents. Should the vessel to avoid itscoming in'conta'ct with any hard 1' '2 v assess substance, I have attached the rubber stopper -'end of the perforation communicating. with.

to the metallic screw-plug. Y

In order to render the explosion of the dynamite or other like compound certain, I prefer to use a fuse of some description, that which 'I have illustrated being a desirable one on acthe chamber is placed what may be called a" .plu-nger, .m, having a nipple formed upon it for carrying a pe'rcussion-cap.- The chamber is closed at the top by a screw-plug, a. When ters Patent, is-

the shell strikes, the plunger is by its momentumv thrown against the plug a with sufficient forceto explode the cap, whereby fire is com municated to the powder forming the fuse,

the explosion of which will detonate the dynamite.

. Having thus described my invention, what I claim as new, and desire to secure by Let- 1. Incombination with a metallic ordnanceshell, an elasticcasing' fitting the bore of the shell,"an inner elastic vessel, and perforated annular rims connecting the vessel with the casing,- for the purpose above set forth.

2. In combination with a metallic ordnanceshell, an elastic casing fitting the bore of the shell, an inner elastic vessel, and perforated annular rims connecting the vessel with the .ing the body of. the

casing, the bottom of the vessel being thicker than and formed ,integral with one ofsaidrims, for the purpose stated.

1 3. In combination with a metallic ordnanceshell, an elastic casing fitting the bore-of the shell, a bottle-shaped inner elastic vessel, the neck of which is attached to the casing, and annular elastic perforated rims connectsubstantially as described.

4. In combination with a metallic ordnanceshell having rearwardly inclined perforati ons in its forward end, an elastic vessel hav-' ing an outer perforated casing adapted to fit the bore of the shell, the vessel and easing connected by perforated annular rims, and a vessel with the casing,

diaphragm extending across the casing below the vessel, substantially as described, and for the purpose set forth.

5. In combination with a metallic ordnanceshell having rearwardly-iuclined perforations 1n itsforward end, an elastic, casing fitting the bore of the shell, an inner elastic bottlewith a rubberstopper,

shaped vessel provided perforated elastic an n ulai rims connecting the vessel with the casing, a diaphragn'i extend ing across the casing belowthe vessel, and means for detonating the contentsof the vessel, substantially as described, and for the purposes above set forth.

In testimony Whereof I afiix my signature in presence of two witnesses.
