Application led October 10, 1919; `Serial No. 829,795.

To all whom t may coneem:

Be it known that I, Ronlrr TEMPLE, a subject of the Kino' of Great Britain, residin f at Bromley, in the county or' Kent, Englan have invented certain new and useful Improvements in Explosivel -Actuated Penctrating Means, of which t e vfollowing 1s a specification.

This invention relates to improvements in explosively actuated penetrating means and has for its object to provide a new and improved device comprising a penetratin member, an explosive actuating charge, an means to detonate the explosive charge, in combination with other structural features hereinafter described.

My invention is especially adapted for use in submarine work, for example, where it is desirable to aix repair plates or the like to the hull of a vessel in a minimum of time and with a minimum of eii'ort,"or where it is desirable to attach projecting means to the hull of the vessel to which or'by which may be secured lines. There vare'nnrnerous other uses to which my invention can' be put.

The embodiment of my invention illustrated in the drawings comprises principally a holder, a barrel and a projectile aflixing member, consisting of a member adapted to bc projected by an'explosive charge into thc metal sheet or body to which it is to be affixed.

Another object of my invention consists in providing a device of the character described in which one holder may be utilized with any number of barrels and projectiles so that the user may attach a new barrel with projectile contained therein with a simple operation.

Another object consists in the provision of mechanism of the character described, in which the user will be' protected from concussion under water.-

These and other objects will'bc more fully described and set forth in the following specification and shown in the accompanying drawings, in which- Figure l is a vertical cross section through a structure lembodyingmy invention, showing the same located against the side of a vessel preliminary to attachment of the missile.

Fig. 2 is a detail showing'the penetration of the projectile after actuation.

Fig. 3 is a transverse horizontal section along the line 3-3 of Fig. 1.",

' mit iow of the line of Fig. 1.

Like characters refer to like elements throughout the drawings, in which a desi `natos what I term the barrel. Located in t e barrel 1s an alxmg projectile member which comprises a fastening means arranged to penetrate'the body to which it is to be attached. This projectile comprises the element b shown as tapered and having spiral grooves to facllitate penetration, and to perenetrated metal into the groove to secure t e rojectile in its aiiixed position, this projecti e being preferably constructed of hlghly tempered steel or the like. Located above/the projectile b is the cup b1 closely fitting the bore of the barrel a, provided with a cup shaped depression forming relatively thin-walls b2. Extending through the bottom of the cup b1 and engaging the upper portlon'A of the projectile b is 4the threaded screw c which normally secures the -projectile b to the cup b as shown'in Fig. l.

An explosive charge of predetermined quan? tity and explosive force indicated by the letter d 1s carried in the cup b1. Located above thc cup secure to the cup b1 and projectile b by Fi 4 is a similar section taken along the b1 Visthe detonator block e normally means of the screw c. `Located. between the detonator block e and the cup b1 above the tough material, such as copper or the like. The barrel ais slightly enlarged to accommodate the block e, forming a shoulder e2 on which the disk g rests as shown in Fig. 1. This detonator block e is provided with a cup or depression inwhich 1s mounted a detonator f, a firing hole e1 leading from the detonator chamber to the explosive charge d.

Located above lthe block e and detonator f is a disk k of copper or the like secured in place by the threaded plug i, which engages a threadedportion of the bore of the barrel a. This lug i is centrally apertured at 'i2 and provlded with a cross slot 2'. for engage .centrally pertured- .0r bored t0 fewer-the,

end of the holder and provided with a longi- `tu inal slot k2 on the lnterior iu which may sli le the lug Z on the sleeve Z. This slot k2 terminates above the bottom of the holder 1 5 und prevents withdrawal of the barrel after onvageineut of sleeve Z with plug The ho der Z: is further provided with an enlarged portion 708 in which is pivotally mounted a detent m mouutedupon the pin IO m1 and havmg a hooked end m2 lnormally engaging the top of the sleeve Z as shown in Fig. l, being maintained in such position by the spring m3 and removable from such position by the handle portion m* which projects outside of the holder k. Screwed into the top of the latter is the handle 7:'1

which also serves to maintain the firing rodjl in the holder inthe seat provided b 'the shoulder i as shown' in Fig. 1. This ring rod is provided' with a firing pin portion y' of considerabl smaller diameter thanythe firing rod andy small opening z" in the bottom of plug' z. A

coiled spring a is located in the holder-'7c f '25 and extends between the top of sleeve Z and.

' the bottom of the firing rod jl as shown in Fig. 1. An aperture 7c is provided'in the upper portion of the barrel av to" permit evress of water from the holder k in actuation of the device.'

The'exte'rior of the barrel a, at the muzzle is externally threaded and engaged by the nut q which is internally apertured to '.iiorin a prolongation of the bore ot the barrel a of less diameter for a purpose to be hereinafter described.v An4 internal shoulder q2 is provided inthe nut g in which is seated a isk g1 of copper, or the like nminally clos-- ing the bottom of the bore oi thc barrel 40 against ingress of water, the upper portion of the bore being sealed by the disk L. Lo-

cated between the disk 91 and the muzzle of the barrel a is the block o 'centrally apertured to form a reduced continuation'of the bore of the barrel and' secured in place by the nut g. v The block o is provided' with a seat 01 and also serves to maintain a disk y) heldy against the muzzle of the barrel a., this disk p being centrally aperti-nedl at p1 to permit relatively easy penetration thereof by the projectile b.

. In the use of my device, for example,

where it is desired t'o secure. a repair plate 'r to a side r1 of a ship or some other submerged body, the holder and muzzle be- 'ing in assembled relation, as shown in Fig. 1, are placed by the user with the end 'of the nut g against plate r which may have a predrilled hole therethrough after which,

o'while grasping the handle k1 the user may disengage the detent 'm from engagement with the top of the sleeve Z, after which the holder c may be forced downwardly' upon the barrel a against the action of th'e s )ring u'ntil'theiring' pin j strikes the disk ,de-

capable of penetrating the- -pressure off the explosive charge until same has built up'tofa desired point, when the screw c will fracture at the notched portionl c1 and the rojectle b with the cup b* will be projected) downwardly 'in the bore of thel barrel a as viewed i n Fig. 1. The sides of the cup b1 being comparatively thin. -will be maintained in close contact with the bore so owing to the expansionI of the. gases, and as l have constructed the cup b1 and the p1o. 'ectile Z) of relatively small mass, they will e rapidly driven thro-ugh the bore of the barrel a, the projectile b passing' through 85 disks p and (j and through the plate fr and side of the vessel r1.' As the projectile and cup arel a proaching the final position shown in 1g'. 2, the bottom of the cup- 'b1 will strike the. copper disk p and he ref.. tarded thereby during. a vrelatively short distance of travel until the bottomof the cup 711 is seated upon the shoulder o1 of block o. When the travel of the cup b1 is terminated ,i

y bv the shoulder o1, the force of the projec holder Ic and be unscrewed from the top of plug t', after which the holder and sleeveI Z may be removed andV a new barrel with projectile, etc., substituted.

l'n the initial assembly of the structureVllO 'v ,the plug i may be engaged by a screw driver in the slot i and rotated to assembled position. As stated before, the disks h and q maintain lthe bore of the barrel a free from water,

l thereby preventing'l dampening of the eX- plosive charge. -Also the impact or concussion from the explosion will not transmitted to the water or to a diver -or other user, this being prevented aty one end of the bore of the barrel by the disk lzy and the other 'end bythe cup b1 and the projectile -b as viewed in Figa 2'.'

I yThis device' is vcapable 'ofnse' not only where it lis desired to attachrepair or other' 125 plates to the sideof a vessel or the like but also where it is desired to aliixy lines, -cables,

or ythe like, for various purposes', in which event it is only necessary to place the end of the barrel against the-side-o the 'body .130

i, into which the projectile is to be driven, as

will be obvious. In this manner laborious and time-consuming drilling, riveting or the like is avoided.

It will also be obvious that there are many other uses to which my invention may be put, and many modifications and improvements-Which may be made, so that I do not wish to be restricted to the use or form shown in the accompanying drawings and described in the specification, except as defined in the appended claims.
