JULIUS KELLER, or roim DU L'Ac, Wiscons n.
DETONATOR.
To all whom it may concern:
Be it known that I, JULIUS KELLER, a citizen of the United States, residing at Fond du Lac, in the county of Fond du Lac and State of Wisconsin, have invented certain new and usefullmprovements in Detonators, of which the following is a specification.
The object of this invention is to improve the construction of detonators used in explosive shells.'
In the accompanying drawings, Figure 1 is a longitudinal central sectional view of a detonator embodying the features of my invention. Fig. 2 is an enlarged view of the forward end of a slidable rod comprised in the detonator, showing-a detent attached thereto. Fig. 3 is a section on line 3-3of Fig. 2. Fig. 4 is aperspective view of the detent. p
The detonator comprises a casing 1 adapted to be secured within the body or casing of a shell. Stationarily mounted within the casing 1 is a ring 2 to which is fixed a firing,
Normally the rod 4 is held against sliding movement by means of a compression spring 7, and by means of a detent 8.. Said etent comprises a base9 lying against the forward Specification of Letters Patent.
end of the rod 4, and two fingers 10 lying in contact with opposite sides of the rod. The
end portions of the fingers 10 are bent to provide yieldable projections 11 'which lie in contact with portions 12 that are stationary with relation to the casing 1.
The detent. 8 is secured to and centered shown) against the arms 10 to force the metal of said arms into said recesses, thus producing the bosses'13. It will be seen that the means herein disclosed for securing the detent to the rod and for centering'the detent thereon is very simple and inexpensive.
Upon concussion, the rod 4 is driven forward in the casing 1 through momentum, the projections 11 .yielding or flattening out to allow the rod to slide.
Iclaim as my invention:
A detonator comprising a casing, a rod slidable axially of the casing, a detent for normally preventing movement of the rod, said detent comprising a base lying against the end of the rod and two arms lying at the sides of the rod, said arms being bent to pro-.
. vide yieldable locking projections, stationary.
JULIUS KELLER.
