IMPROVEMENT IN GONCUSSION-FUSB FOR EXPLOSIV SHELLS.
T0 ALL WHOM IT MAY CONCERN: i
Be it known that we, ANDREW J. SIMPSON, of the city and county of Philadelphia, 'and State of Pennsylvania, and JIIN J. JnNlzzncK, ofthe city and countyof Washington, District of Columbia, haveinvented anew :1nd useful Improvement in Concussion-Fuses; and we do hereby declare the following to be a full, clear, and exact description of the nature thereof, which will enable others -skilled in the art to which it appertains to fully understand and construct the same, reference being made tothe followingdrawings, making part of this specification, in which o Figure 1 represents aside view of the fuse, illustrating our invention.
Figure 2 is a transverse vertical section of the same, taken through the middle of its length.

This-invention relates to a new and useful improvement in fuses, of that class which is attached to projectiles which are exploded by the fulminate being ignited' when the projectile reaches its destination. It consists in providing atapering or cylindrical case, with a plunger, to which is attached a Wire, one end encased within the fulminate, contained in a chamber, which is rmly secured to the inner or lower end of the fuse-oase, so that when the projectile is discharged` and strikes any object, the plunger, by its inertia, will slide or rush forward in the fuse-case, carrying 'the wire with it, thus 4igniting the fulminate, exploding a small quantity of powder in the case, blowing out the bottom rivet, communicating with the powder inV theprojectile, v.and exploding the same, las will be hereinafter more fully described.
i In the drawings A represents theA encasing-tube or fuse-case, of a tapering or cylindrical form, and hollow from its lower'- or inner end to a point about one-sixth fromrits other end. The inner periphery is likewise tapering, and has, for a distance ot" about one-third of its length, a' screw-thread cnt thereon, in which dt the screw-threads of the`fulminatechamber B. This chamber is hollow, receiving a tube, C, into which the firlminate is introduced, and has an opening, a, on its upper and lower end, through which passes the frictiom wire b, afterbeing encased Within the fulmnate. The friction-wire is hooked at both ends. The lower end or hook catches under thevtube C, and prevents the accidental withdrawal of the wire at the other end. The upper hooked eird is somewhat above the tube, and catches above the plunger B, which fits snugly in the hollow of the fusecase A. The plunger is provided with a central perforation, through which passes the friction-wire, thus holding-the plunger on the fulminute-chamber. We interpuso a flexible washer, c, between them, for preventing any untimely ignition of the `fulminate by concussion or jarring. A pin, passes through the case A and the fulminate-chamber B, and supports the fulminate-tube- C immediately against .the hooked end of the frictionwire. The space e, below this, is lled with powder, which rests on a rivet or head fwhich is iiush with the bottom of the fuse-case A, as readily seen in iig. 2, and prevents the said powder from dropping out. The pin d, while supporting the fulminate-tube, will prevent its iiying back during ilght. It will be seen that, by the plunger iitting .snugly in the hollow of the case, there will be no ignition of the fulminate by lateral motion of the plunger, and any accidental jars or shocks will be checked or broken by the washer. The conical form of the case A renders unnecessary any device for holding it in the oharging-aperture of the projectile. It can be readily packed, and no parts of the fulnrinatel are exposed, and the fuse is not liable to accidental explosion.
The operation-is as follows: The case .is inserted to its fullest extent in the charging-aperture of the projectile. When the la'tter is discharged and reaches its destination, -it is stopped by impingement againstthe object which it strikes. The plunger, by its inertia, will move forward in the fuse-chamber, drawing the friction-wire with it; and as part of the wire is embedded in the'fulminate, the latter will be ignited and explode the powder in the case, blow out the rivet at the bottom of the ease, and communicate with the charge in the projectile and explode it, as is readily perceived. The simplicity and practicability of the device are plainly evident. The cylindrical case is closed' on all sides, and thus none ofthe internal parts are exposed, and its outer face is unbroken and can readily be inserted in the charging-apertureof the. projectile. It requires no devices or means for retaining it in place. i v
Having thus described our invention, -what we 4claim as new, and desire to secure by Letters Patent, is
In combination with the tapering closedA case A We claim the plunger D fitting snugly therein, the fulminatechamber B, fulminate-tube C, friction-wire b, washer c, pin d, and powder-chamber e, all arranged therein, and constructed as herein describedfor the purpose specified.
To the above we have signed our names, this 14th dayof March, 1867.
