Ehm-GRENADE.
Specification of Letters Patent.
Patented Oct. 21, 1919.
` Application led August 17, 1917. Serial No. 186,704.
To all 'whom t may concern.'
Be it known that I, JOHNl C. MILLER, a citizen of the United States, residing at Wissinoming, Philadelphia., county of Philadelphia, and State of Pennsylvanla, have invented certain new and useful Improvements in Hand-Grenades, of which the fol-` lowing is a specification.
This invention relates to hand grenades adapted to be thrown, in trench warfare, or dropped, asa bomb from an aeroplane.
My object is to prd/vide a simple and re- V liable grenade which can be locked or made secure when being shipped or carried about and readily conditioned for use without danger to the soldier or aviator using it.
A further object is the provision of a hand enade of novel construction wherein lring can only occur by a positive separation of the handle and firing pin from the grenade proper as, for instance, when the parts are set for separation and the grenade is actually thrown or allowed to drop.
In carrying out the last-named object of the invention, I rovide a handle and firing pin adapted to e retained in the hand of the soldier when the grenade proper is thrown or dropped, and combine therewith novel locking means for holding the firing mechanism or hammer until the handle and firing pin have separatedv from the grenade proper.
It has been found necessary in hand grenades to provide for the escape of the as incident to the explosion of the cap whlch ignites the time fuse. In the present invention there is provided a cap of novel form which is provided with frangible means so that when the cap is exploded at the time the renade is thrown, the rangible portion willgbe blown out, allowing the gases from the exploded cap to escape. The construction of the grenade is such that when it is thrown or dropped, the separation of the parts leaves an opening from the body of the grenade t0 the atmosphere and, consequently, the gas vents from the exploded pThe invention contemplates, still further, the provision of a hand grenade embodying certain improved instrumentalities and novel arrangements and combinations of parts appearing more fully hereinafter.
In the accompanying drawings Figure 1 is a side elevation showing'the parts in locked condition, ready for shipplng or handling;
Fig. 2, a longitudinal section with the parts in locked condition;
Flg. 3, an end elevation; Fig. 4, a detail view showing the handle or knob in unlocked condition; Y Fig., 5, an enlarged cross-section on line 5 5, Fig. 2; v
Fig. 6, an enlarged longitudinal section showing the -liring stem in the osition it assumes as it leaves the locking alls; and
Fig. 7, a detail of the explosive cap. The body of the renade comprises a tubula'r part' 1 having lieads2 and 3 detachably screwed thereinto. The head 3 holds a disk tial y semi-spherical flange cap 6 is held between the collar 3 and the disk 4, within which is the time 7. By removing the head 3, the cap 6 can be taken off and the proper length of fuse inserted, according to conditions of use. -One end of the fuse is passed through a screw-threaded 'bushing 8 threaded into a hub on the disk 4, the end of the fuse being flattened out and clamped byl said bushing 8. The other end of the fuse connects with the detonating cap 9, which is set into the disk 4 and lies within the body 1 so that it will explode the explosive charge contained within the space 10 when the fuse 7 has burned up to the cap 9.
The disk 4 is provided with a boss 11 which lits into one end of a tube 12 whose other end is received in a recess 13 in the head 2.
The improved cap 14, which is shown in detail in Fig. 7, is set in a hole in the boss 11 and arranged so that when it is exploded it will ignite the end of the fuse 7. The head of the cap is provided with depressions 15 which extend almost through said head, leaving the thin, frangible portions 16 which are blown out when the cap is exploded, thereby permitting the gas resultingV from the iirin of the cap to `blow into the interior of the tue 12, from which it escapes, as will appear hereinafter. The depressions 15 serve as Spanner holes so that the cap may hammer in retracted position to prevent it from accidentally firing the cap at those times when the grenade is being shipped or handled. To condition the grenade for use in warfare, the pin 20 has toirst be removed.
Slidable within the nipple 18 and through the head 2 and within the tube 12, is a firing hammer having a tubular stem 21 which is provided with an annular groove 22.to receive the pin 20. The hammer is provided with a head 23 having a point 24 adapted to strike the cap 14. Surrounding the stem 21 and located in the tube 12 between the head 23 and the head 2, is a coil spring 25 which is under compression when the firing hammer is in normal position so that when said hammer is released, it will be driven forward to cause the point 24 to strike the cap 14 and explode the latter.
The end of the nipple 18 is provided with al concavity 26. Extending transversely through the stem 21 is an aperture 27. Located in the aperture 27 and proJecting into the conoavity 26 is a pair of balls 28.
Telescoping over, and secured to, the nlpple 18 is a tube 29 which is provided at its outer end with a bayonet slot 30. A knob or handle 31 is slidably received within the end of the tube 29 and has a pin or stud 32 adapted to play in the slot 3() and to-be locked in the portion 30a thereof. A firing pin 33 is slidable through a web or s plder 34 extending across the tube 29, said pin being provided with a pointed end 35 which lies between the balls 28 and keeps them projected into the concavity 26, thereby locking the iring hammer in retracted posltion with the spring 25 under compression. Interposed between the cross-piece 34 and the knob or handle 31 is a coil spring 36 which is adapted to shift the knob 31 on the firing pin 33 until the knob is arrested by the head 37 on saidl ring pin. Y
Normally the pin 32 is in the off-set 30a and the knob 31 is located inwardly in relation to the head 37; the end of the iiring pin 33 is between the balls 28. Consequently the firing hammer is locked and the spring 25 under compression. Assuming, now, that the locking or safety pin 20 has been removed and it is desired to throw or drop the grenade, the knob 31 is turned to brin 'the pin 32 into the longitudinal portion o' the bayonet slot 30. The spring 36 pushes the knob 31 slightly outwardly until the head 37 arrests the knob. The top of the firing pin 33 still remains inte osed between the balls 28. The grenade is t en ready for use. To throw or drop the grenade, the user grasps the tubular handle portion 29 with his hand resting against, or near, the knob 31. As soon as the hand is slid along the tube 29, the knob 31 is withdrawn and pulls with it the firing pin 33, whereupon the balls 28 drop to the interior of the stem 2 1. When'this happens, the spring 25 instantly snaps the hammer to frlng position, thus exploding the cap 14 and igniting the '-fuse 7. The knob 31 and firing pin 33 remain in the hand of the soldier, but the remaining portions .of thev grenade are thrown or dropped. The gas resulting from the explosion of the cap 14 passes by the head 23 and through the stem 21 into the tube 29, thence to the atmosphere. When the fuse 7 reaches the detonator 9, the grenade explodes.
Having thus described my invention, what I claim as new and desire to claim by Letters Patent, is
