Title: Improvements in grenades, and the like
IPC: F42C14/02
Filed: 1925-06-25
Abstract: 260,318. Lebensart, S. June 25, 1925. Projectile fuzes. - Grenada fuzes of the type having a universally moyable weight, and a safety device actuated during a preliminary movement of the weight, have a contracting spring ring which progressively controls the safety device. Fig. 1 shows a hand grenade comprising an explosive charge Y which fills the space between a fuze casing R and an externally ribbed outer casing U. The detonator charge X is fired by a primer B' which is pierced by a firing pin A<1> extending from a unit A which can telescope in the fuze casing with respect to a second unit B carrying the primer. Mounted between concave portions on each unit is a spherical weight C which, subject to the control of certain safety devices, can move in any direction to cause ignition. During transport, the fuze casing is closed by a detachable cap H which is turned by projections H<2> to cause a spring G to eject the cap and arm the bomb. The safety devices which prevent firing under the normal shock of throwing, under exceptional shock at the time of throwing, or after a missfire or " blind " impact, are under the control of a coil-spring rihg L the contraction of which, after removal of the projection F<4> on the cap H, is governed in steps by sleeves E, W. M, the ring acting as a stop for the projection A<3> on the firing-pin unit A to prevent the telescoping movement of the units A, B until the safety locks are removed. Fig. 6 shows the ring L after it has escaped from the sleeve M to a waiting position on the sleeve E during the preliminary movement of the weight caused by the shock of normal throwing. If abnormal shock occurs, the ring passes into a groove E<2> and locks the firing pin. If the throw is normal, the ring escapes to the sleeve W after a delay due to the forcing of a split collar E<5>. The ring then occupies the " ready for ignition" position shown in Fig. 9, when the units can telescope to the full extent on impact. If a missfire occurs, the ring escapes to the position shown in Fig. 11 between the sleeves M, W, thereby locking the sleeves against the full collapsing movement which is necessary to cause ignition.
