pin when the b impact.

To these and other ends, the invention consists 'n the construction, tion of elements described hereinafter and point- I specification.

A practical embodiment of the invention is illustrated in the accompanying drawing, wherein:

Figure l is a longitudinal sectional view of the fuse with the parts adjusted for delay firing action;

Fig. 2 is a similar view with the for instantaneous firing action;

Fig. 3 is a view showing the fired position with the adjustment of Fig. 2;

Figs. 4 and 5 are sectional views on the corresponding lines of Fig. 1;

Fig. 6 is a sectional view on the line 6-6 of Fig. 3;

Fig. 7 is an inside face view of the plug of Fig. 6.

Referring to the drawing by characters of reference, there is shown a fuse, comprising a body 5 having threads 6 for attaching to it a bomb casing and formed with a flanged head 7 having a. central recess 8. The inner end of the body :arries an eccentrically positioned primer-detoparts arranged iator 9 which is in communication with 0011-,

H, the passage 18 conmovement of a firing erging passages l and aiming and providing for in I2 and the passage l l arranged to conduct he fiash from a primer-delay train l3. A shear in I4 in the body holds the firing pin [2 clear f the primer-detonator and with its outer end xtending into the recess 8.

A striker l carrying a firing pin !6 in its inner id is partially disposed in the recess 8 of the my and includes a fianged head ii overlying Le head 1. Blocks I8 interposed between the eads and I! normally maintain the inner end 001111. 1938, Serial No. 228,117 (01. 10239) 3, 1883, as G. 757) of the striker in spaced relation to the fioor of the recess 8 and hold thev known manner by a cap l9 which has a spindle 2G threaded in the striker. Vanes 2i on the cap serve in the usual manner to provide for rotation threaded in order to free the clear.

A bolt 22 disposed radially of the fuse has its outer portion passing through an opening 23 in the head 'I and its inner portion inserted in an opening 24 in the striker. The opening 26 is in communication with a passage 25 which receives the outer end of the firing pin l2.

blocks it which fall aligned with the passage 25 so that it may receive the end of the firing pin when the striker is moved inwardly.

The bolt is rotatably mounted so that it may be turned to present the passage 26 to the firing pin as shown in Fig. 1 or to present a solid surface to the firing pin as shown in Fig. 2. It is held in either one of these positions of adjustwhich is selectively In Fig. 2 the parts are adjusted for instantaneous action and when the striker is driven rearwardly the severed inner end of the bolt (Fig. 3) drives the firing pin l2 into the primer detonator 9, shearing the pin I4.

is completely un- I claim:

1. In a fuse, a body having a recess in its front part and having passages, a primer-detonator carried by the body at one end of the passages, a primer-delay train in communication with one of the passages, a first firing pin in the other passage, a shear pin in the body and supporting the firing pin with its outer end extending into the recess of the body, a striker having its inner end disposed in the recess of the body, a second firing pin carried by the striker in line with the primer-delay train, a bolt rotatably mounted in the body and having a shearable inner end positioned in the path of the first firing pinto actuate said firing pin, said inner end having a passage arranged to receive the end of the first firing pin in one position of adjustment of the bolt, and means for selectively holding the bolt with its passage in line or out of line with the first firing pin.

2. In a fuse, a body, a -firing pin carried by the body, a striker movable relative to the body, a

bolt rotatably mounted in the body and having a shearable inner end supporting the striker and positioned in the path of the firing pin to actuate said firing pin, said inner end rotatable to clear the firing pin in one position of adjustment of the bolt, means for selectively holding the bolt in the path of or clear of the firing pin, and elements of a second firing mechanism carried by the body and striker.

3. In a fuse, a body, a firing pin carried by the body, a striker movable relative to the body, a bolt rotatably mounted in the body and having a shearable inner end inserted in the striker and positioned in the path of the firing pin to actuate said firing pin, said inner end rotatable to clear the firing pin in one position of adjustment of the bolt, means for selectively holding the bolt in the path of or clear of the firing pin, and elements of a second firing mechanism carried by the body and striker.
