A. H. MmGLEY. PERCUSSION FUSE FOR EXPLOSIVE PROJECTILES. .APPLICATION FILED MAY 23. I9I7`.

sigisiijj To dll whom t mag/concern: I i' Be it .known that I, AIBERT HENRY MIDG- LEY,a-subject of fthe King of Great Britain and Ireland, andresiding at Warple Way, v.Acton Vale, in; the county of Middlesex, f England, have invented certain new and useful Improvements in and Relating to Pery cussion-,Fuses for Explosive Projectiles, of 1 which thefollowin'g is a specification.

.1This;invention,relates to percussion fuses for explosive: projectiles and more particularly. for projectiles intended to lbe used. with l 3a smooth bore gun, such as a Stokes gun of the :kind-infwhich the striker'andthe cap gar'ecarried by two separate blocks capable 'of:axial,movement relatively to eachother :and 'are keptA in an .inoperative Vposition Y by f a spring anda suitable member interposed fbetween the twoblock's. Y

1 It'has previously been proposed in a perv-cussiony fuse-fin which the two pellets the blocks ecarrying'; the striker and the cap 1 Yrespectivelyy are'V capable of axial movement relatively toeach other, to keep the blocks finianinoperative vposition by a safety memt ber interposed directly between the striker the percussion cap, said safety member ybein'gkept in-its safety position by means Vprovided insidethe fuse holder and being `rOtated therein by said lmeans when the pro,- V.fjectile'is-ired morder to remove the Sportionof the safety member lying directly b'etween -the` striker and the percussion fcap from suchposition; Y

' The invention consistsfin arranging' the V4safety memberin a percussion fuse of the Y'kind ir'stiabove referred to, in such apositinasto-.bei directly-interposed between the striker and the cap and retaining it in its j inthe arrangement according to the present invention the rotation of the shell within the gun is not dependedupon for the removal of the safety member, such removal taking place-during the -flight of the shell through ytheair. The-invention also consists in the provif sion of means for preventing the'fuse being assembledunless thel safety member lies directly betweenthe percussion .cap and the striker, such means preferably consisting Qin the provision of a ridge and corresponding Vdepression on the two blocks respecv Specification of Letters Patent i ,safetyposition by .means provided outside; the` fuse holder. It lwill thus be seen" that- STATES PATENT OFFICE nisEriIiiNRriumeLEY, or' AoroN'yALE, ENGLAN), `AssIcfNc'Jrtolijf01m-inutil? To v VCHIABLES'ANTHQNY VANDERVELL; or AcroN VALE' ENGLAND; Y

The invention is illustrated by wayof ex-l .ample fin the accompanying drawings in which,

Figures 1 and 2 are two sectional eleva- `tions at right angles to each other, and

Fig. 3 is a sectional plan of the im.

proved percussion fuseas intended to be luSed in conjunction .with aV projectile for a -St0kesgun.- .i,

Referring to the'drawings; a. is the holder I a conical seat 'a1 and; is preferably provided with abrass liner. a?, and vZn is a cover which is'fformed; with a conical seat b1 arranged oppositethe seat a1 formedon the'holder a.

of the percussion fuse which is formed with' c is-the block carryingthestriker d and e` -the block carrying the percussio-ncap f, both Ablocks being constructed in the form of short truncated cones lodged in the conical seats b1 and al i respectively 'and axially guide g attached to the block e- The two blocks c and e are kept apart from 'each and e respectively and a safety1 member .preferablyconstructed inthe form of a sector is interposed between the two blocks.

and ,the capbeing preferablyformed with a depression'Y y' fin` order to receive.. the point of the striker d while still positively separating it f'rom the'l cap #.15 The safety meml`ber may be retained in its position by means of a tape 7c which is attached thereto at one end and is wound around the fuse holder a and secured thereto at its other end by means of a safety-pin Z provided with a cord Z1 for facilitatin its removal and engaging in holes provided in suitable metal lugs m m1 attached to the tape la Means are preferably provided for preventing the fuse being assembled unless the safety member is interposed directly between the percussion cap and the striker. Such means may consist of a ridge 01 provided on the block c and a corresponding depres-
