Time-Fuse FOR, SHELLS.

Application tiled February 6, 1894. Serial No. 499.253.

To all whom it may con/cern:` f

Be it known that l, HENRY TOLLEY, manufacturer, a subject of the Queen of-Great Britain, residing at IVeaman Street, in the city of Birmingham, England, have invented a certain new and useful Time-Fuse; and l do hereby declare the following to be a full, clear, and exact description of the invention, reference being had to the accompanying drawings, which form part of this specification, and for which invention Letters Patent of Great Britain have been granted, dated the 9th day of May, 1898, No. 5,098. Y

This invention relates to improvements in time-fuses or combined time and percussion fuses to be used primarily in connection with hollow projectiles, whereby the fuse is hermetieally` sealed until the moment of withdrawing the eoned safety-pin, and is also adapted to` ignite the bursting charges of them at a predetermined time after firing.

My invention also relates to that classot fuses having sectional casings-tted with a composition ring and with scale of time-marl'- ings upon one of the parts, which is in communication with the magazine. New the time-settings of such fuses are apt to become disarran ged owing to the shock oi' diseharge that is to say, the shock received upsets the time-setting by loosening and disarranging the position of the composition ring relative to the iiash-hole-so that there is no guarantee that the exploding charge of the shell will be ignited at a predetermined period vafter discharge, as arranged by the setting.

My invention has for its object primarily the rendering of. the time-setting unchange able, whereby the shell fired true to the setting'.

Figure l ol the accompanying drawings represents, partly in vertical section and partly in elevation, a time or percussion fuse constructed according to or having improvements made according to one form oi' my invention. i p

It will be seen that the fuse, which is atitaehed to the fore part of a shell, is composed of two primary parts-wiz., a head or dome part and a body part, with the base part o the former eoned or made alike unto an annular wedge, which takes arm bearing and tits tightly Within a like-shaped eoned socket SPECIFICATION forming part of Letters Patent .Nol 557,454, dated March 31, 1896.

made within the middle ofthe fore part of the body. I

Fig. 2 represents a side elevation of the said 5 5 self-elamping timefuse, Fig. "l, and which 'View shows the time-markings upon the head and also the arrow upon the body part whichv i indicates the position of the Hash-hole in the said body, .so that when the head is turned 6o more or less round relative to the base the composition ring is also turned with the tim markings, and so a greater or less amount of composition is allowed to burn before the powder in the magazine is/ignited from a iiash- 615 hole. Fig. 3 represents in vertical section the pri mary parts of the said time-fuse separately,

showing more clearly the taper or Wedgeshaped outer walls at the base of the head part and also the like wedge-shaped inside 7c,

walls of the socketed body part. lWhen the said parts are together, as inl Figs. l and 2, the concussion due tothe shock of the discharge on tiring tightens or further jams and' hermetieally seals the one component part 75 within the other, hence no liability of derange- .ment of the said parts relative to each other after setting, although the said parts when )ut together are ca able ot' beine' turned for l n z:

setting by a key being applied to the nut- 8o shaped crown of the head. Fig. 4 represents an elevation of the head or dome part separately, showing the ring of composition lying!` within a nearly annular recess formed around the periphery of the coned base of the head. t5l

Fig. 5 is a horizontal section of Fig. l upon the dotted lines .r af, showing the nearly annnlar groove wherein the composition lies and also the position of the flash-holerelative to the detonating fulminate at the eommenee- 9o Fig. is an ment of the ringof composition; inverted plan of Fig. i, showing the eoned base. Fig. 7 represents a top side plan ofthe body part, showing the chambered interior with a coned seating or socket for the recep- 95 tion of a like-shaped base or foot of the head part. Figs. S and 9 arc vertical sectional views of modifications.

The same letters of reference indicate cor responding parts in all the 1i gures of the drawi oo ings.

A is the time-fuse, iitted to or screwed into the fore part of a shell. The said fuse consists ot' two primary parts-viz., ahead a and a part b. The head aconsists of ahol- V'low dome ct', having a solid and nut-shaped crown a2 and a coned or annular wedge-shaped base or foot as, adapted to take and t tightly within a like cone-shaped annular socket or seating b', formed or sunken within the midt dleof the fore end part b2 of the said body part b, which has a screwed tail end or-shan b3, by which the same is connected to the fore part of the shell c.

Referring back to the head part, the same is fitted with a 'nearly annular recess a4 for the reception of the composition d, which starts from the detonating fulminate e', located at the bottom of a detonating chamber e, having fitted and working within it a plunger e2, having a needle e3, and kept in its ing the pin e4, also closes the hole in the metal d5 vacated 'by 'the safety-pin on the said plunger being thrown forward when iii-ed.

' The head part a is attachedly connected to the body part Pb by keep-screws f passing through screweanies'in thesidesbrme Sarti f b'ed'y part, and with -the inner ends of the same taking into the annular groove or chan-- 4nel d, sunken around the conical base part a3. YThis channel a,6 has a clearance sufficient to admit of the coned base of the head going fully home into the cone-shaped socket of 'the .body part.x New this body has a vhash-hole l It-has also a vent b4 for escapeof `gas from g made through the walls of vits inner side and before which the c'arrow comes and which passes to a powder-charged channel h, leading to a powder-charged magazine i in communication with the interior of 'the shell.

the composition d, and by the burning of a greater or less'porticn of whichthe time for A. the bursting of the shell is regulated,'so that las the time-markin gs a? are turned relatively to the position of the arrow so a greater or less amount Vof lcomposition d is allowed 'to burn before thesame-reaches 'the Hash-hole g. The position of the composition is represented by the markings.- i' V Figlj represents a further form of my 'inven'tion. f In this arrangement the composiv vtion is embedded within a nearly all-round channel of. a supplementary ring coming upon the top side of the .headand with the boundary edges made taper in common with 'the outside walls of the body, and kept clamped #fully home by the inside coning of the mouth of. the head.

ais the head, consisting of a dome-shaped fore part having'aturning-nut a2 at its crownA l and with the base or mouth as inside coned at a', which takes in common upon the coned sides or'edges'm2 of a composition-carrylng ring m'and upon the coned sides b2 of the head b, having a flash-hole g and channel h leading from it to the magazine, which is in communication with the bursting charge of the shell, The nearly `all-round composition ring is marked d, and d2 is an interposed washer or wad.` The ring m is prevented from rotating by a keep-screwfmhile the said head is attachedly connected to the body part by the upper end of the stock bs. of the latter taking into a recess a5 in the'inside crown of the former, and with pins or screws f'taking laterally through the walls'o the said head and through an annular recess 'b4 cut around the stalk b3, thus admittingo'f the inside'contact-surface of the head being slightly removed from the bodywhen required for timesetting.

I wish it to be understood that lay no claim to the composition ring, 'time-burning scale,

detonating adj uncts, and other parts found in fuses no w in use; but,

Havingfully described my invention, what I desire to claim and lsecure by Letters Patv l. In a time or 'percussion fuse, the combination with the primary and component 'sections, one of which is formed with a coneshaped socket while the other is cone-shaped to fit said socket, of a composition ring itted into an annular space -on the coned face of one of said sections and retained in position y and hermeticallyfsealed by the wedging action of the said sections, .substantially 'as described. l

In a time percussion fuse, the combination of the body part b, having aconeshaped socket and retaining-screws f, f, with the head part a, cone-shaped to it said socket and'having the annular groove a, Vfuor the re'- ICO ception of said screws, said groove having .4

suiicient clearance'to'ad'mit of the head part i I IO going fully home in said socken-substantially as described. v

In testimony-that I claim the foregoing I have hereunto set myhand this 9th day of January, 1894. m"-
