Application led November 14, 1906. Serial No. 343,367.
To (LU who/1t t Netty concern:
Be it known that l, ALFRED MAURICE MA- Zan, a citizen of the Republic of France, residing at Jeannette, in the county of lestmoreland and State of Pennsylvania, .have invented certain new and useful improvements in Fuses, of which the following is a specification, reference being had therein to the accompanying drawing.
This invention relates to fuses adapted for use with projectiles.
The primary object of the invention is to provide a fuse of novel construction adapted to be exploded by the release of a hammer within the fuse caused by the meeting of an obstruction by the projectile which carries the fuse.
A further object of the invention is to provide a fuse having a powder chamber formed with perforations to insure a full and free explosion of the powder within the chamber, when the fulminate receives the impact of the hammer.
The invention comprises a hollow cylindrical barrel or casing, a hammer arranged therein, means for securing the hammer within the casing in such a manner as to insure its release when the projectile strikes an obstruction, and a powder chamber and fulinmate.
The construction of the improvement will be fully described hereinafter in connection with the accompanying drawing which forms a part of this specilication, and its novel features will be defined in the appended claims.
1n the drawing, Figure 1 is a central longitudinal section of a fuse embodying the invention, and a portion of a projectile casing to which the fuse is secured, Fig. 2 is a similar view of a inodilied construction, Fig. 3 is a fragmentary longitudinal section of another modification, Fig. 4 is an end view of Fig. 1 on a smaller scale, Fig. 5 is an end view of Fig. 2 also on a smaller scale, and Fig. 6 is a side elevation of the spring-holder for detachably securing the hammer of the fuse within the casing.
The reference numeral 1 designates the rear wall of a projectile to which the improved fuse is to be secured. In Fig. 1 this wall 1 is provided on its inner face with an annular internally threaded collar 2 within which is secured the externally threaded enlarged end 3 of a hollow cylinder 4 constituting the casing of the fuse. In Fig. 2 the rear wall of the projectile is formed with an opening 5 internally threaded to receive the threaded end of the casing 4, which latter in this instance has its rear end flush with the outer surface of the wall l.n
The construction of Fig. 1 is adapted for use with projectiles made of a plurality of connected sections, while that shown in Fig. 2 is designed for general use with projectiles comprising a single piece, or so constructed that the fuse must be inserted through the rear end wall of the projectile.
Within the cylindrical casing 4 is arranged a solid cylindrical hammer 5, provided at each of its ends with an annular rib 6, to reduce the frictional contact between the hammer and the casing. The rear end of the hammer is formed with a threaded socket 7 to receive the threaded end of a stem S, the opposite end of which is provided with an oppositely beveled head 9, adapted to be engaged by the lingers 1() of a conical holder 1 1 formed with an annular flange 12 adapted to lit against a shoulder 13 formed adjacent to the rear end of the casing and to be secured in position by a screw-plug 14 fitting the end of the casing.
Referring to Figs. 1 and 2, the forward end of the fuse casing 4 is closed by a cap 15 having a rearwardly extending threaded liange 16 fitting over the end of the casing and aforwardly extending internally threaded iiange 17 fitting over the adjacent open end of a cylindrical chamber 18 adapted to contain a tube 19 of paper or soft metal, one end of which extends through an opening 20 in the front wall of the chamber 18, while the opposite end extends through a central opening 21 in the cap 15. An integral collar 22 surrounds tne opening 21 on the rear face of the cap 15 to serve as an anvil to receive the impact of the hammer, and over this collar 22 is fitted a cap 23 of soft metal, containing a fulminate 24. The tube 19 is twisted as shown and adapted to contain powder. The time required for the burning of the powder within the tube 19 after its ignition by the explosion of the fulminate 24, depends upon the degree to which the tube is twisted. Upon the forward end of the chamber 1S is fitted an internally threaded powder chamber 25 provided with perforations 26 in the front of the chamber and perforations 27 in the perimeter thereof. rFliese perforations are plugged with parai'lin or other soft material to prevent the powder within the cha1n ber from escaping into the projectile chamber.
The utility and operation of the improvement constructed as above described will be readily understood, Normally the hammer 5 is held in the position shown in the drawing by the engagement of the head of the stem with the spring fingers 10. The instant that the projectile which carries the improved fuse strikes an obstruction the hammer will be released and its impact against the fulminate 24V` will explode the latter, thus igniting the slow burning powder within the tube 19 and then the quick-burning powder withinW the chamber 25.
In Fig. 3 is shown a modification in which the intermediate chamber 18 is omitted, the chamber 25EL being directly connected to the iange 17 of the cap 15. ln this instance the chamber 25L is made of greater diameter than the chamber 25 to permit it to be screwed over the flange 17 to rest flush with the iiange 16 and the .[lange 17 is eXteriorly threaded instead of internally threaded as in Figs. 1 and 2.
The empty space within the chamber 18 receives the gases from the twisted tube or squib and prevents the explosion of said chamber.
What l claim and desire to secure by Letters Patent, is
1. A fuse comprising a barrel, a cap closing the forward end thereof and having a central opening, a powder chamber secured to said cap, a fulminate arranged over the opening in the cap, a hammer within the barrel, a headed stem projecting from the hammer, a plug closing the rear end of the barrel, and a spring-holder for said hammer held in position by said plug.
2. A fuse comprising a barrel, a cap closing the forward end of the barrel, a chamber secured to said cap, a twisted tube or squib within said chamber, a fulminate for igniting said squib, a perforated powder chamber secured to the squib chamber, a hammer within the barrel, and means for supporting said hammer.
3. The combination with a projectile casing, of a fuse barrel or casing, secured there to, a screw plug within the rear end of said barrel, a spring holder secured by said plug, a hammer within the barrel, a stem removably secured to said hammer and engaged by said spring holder, a powder chamber at the forward end of said barrel, and a fulminate adapted to be exploded by said hammer to l ignite the powder within the powder charnber.
In testimony whereof I affix my signature in the presence of two witnesses.
