, To all whom it may concern:
- g body 3.
- primer 2 Be it known that I, EDWARD W. FNEWELL, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented new and useful Improvements in Percussion- Fuses for Projectiles, of which the following is a specification.
This invention relates to percussion fuses,
and more particularly to the type adapted to be employed in connection with pro ectiles which are detonated by impact.
The principal object of my invention is to provide a percussion fuse of the above character of few parts and adapted to be cheaply manufactured.
Other objects and advanta es will appear in the following more detai ed description of the invention.
In the accompanying drawing; Figure 1 1s fuse'embodying my invention and applied to a projectile, showing the parts in normalposition; Fig. 2 a similar view, showing the parts as positioned just after impact of the projectile; Fig. 3 an elevational View of the trip member for the firing plunger; and Fig.
4 an end view thereof.
According to my invention, a cage l-is provided, havin a primer 2 mounted at the ;rear end thereo and adapted to'be screwed into the forward end of the projectile Within the cage 1 there is mounted a firng plunger 4, positioned, to strike the when released, and preferably cup shaped to contain a coiled spring 5 having its outer end abutting the interior wall 0 the nose 6 of the projectile,
* nose 6.
the spring being held in position by a rod 7 screwed into the For eflecting the retraction of the firing plunger 4 and the compression of spring 5 U upon impact of the projectile a longituinally movable inertia member 8 is rovided having a pluralitytof resilient wlngs 9, positioned as shown in Fig. 3 when not restrained.
The wings 9 areprovided with inwardly extending flanges 10 at the inner ends for.
engaging over the inner end of the flanged ends of the a central sectional view of iapercussion I spring and t en said p unger,
.thenose 6, having first compressed the wings 9 so that they 11 of the cage.
The cage is now screwed into thecan enter the reduced bore rojectile body 3, the parts beingpositione d as shown in Fig. 1.
When the projectile is fired and'hits, the impact thereof causes a forward movement of the inertia member 8, carrying with it the firing plunger 4 and thereby compressing the spring 5.
' As the member wlngs 9 are freed mm the restricted lbOI'G 11 of the cage and fly out into an enlarged bore 12 thereof, so that the flanges 10 are freed from engagement with the end of the firing plunger and said lunger being released, is shot rearwardly y t e action of the compressed spring 5, so as to strike the primer 2 and thus detonate the projectile. x The opening formed by the flanges 10 for the passage of the plunger may serve as a guide for the plunger, if desired.
The improved fuse mechanism; 1s also adapted to be employed in connection wlth tor edoes, since the construction" is water ti t.
I claim as new and desire to secure by Letters Patent, is:
8 moves outwardly the aving now described my invention, what fuse mechanism mounted therein and comprising a firing plunger said plunger, and a. Iriember movable by inertia upon impact of the projectile for first retractin the plunger-to compress said plunger, thereby movement of the plunger by the spring.
2. In an explosive projectile, the combina tion with a body portion and a nose, .of a fuse mechanism mounted therein and comrisin .a firingplunger, a spring acting'on and a member movable by a spring acting on adapted to release the I permitting the reverse,
inertia upon impact of the projectile for retracting the plunger to first compress said spring and then adapted to release the plunger to permit'movement thereof by the spr g- Y 3. In an explosive projectile, the combinationwith a body portion and a nose, of fuse mechanism comprisi g a firing plunger, a
spring mounted between the nose and said plunger, and a movable member normally engaging said plunger and operated by inertia upon impact of the projectile for moving said plunger to compress the spring, said member being released from engagement with the plunger near the end of its movement. I t r 4. In an explosive projectile, the combination with a body portion and a nose, of fuse mechanism comprising a firing plunger, 3.
spring mounted between the" nose and said plunger, and a member provided with sprin wings, normally confined to engage said plunger and adapted to-release the plunger upon movement'by inertia under impact of the projectile.
In testimony whereof I hereunto set my hand. t
EDWARD W. NEWELL.
