To all 'LU/tom t may concern.'

Be it known that I, FRANK L. NICHOLS, a citizen of the United States of America, residing at Stamford, in the county of Fairield and State or' Connecticut, have invented certain new and useful Improvements in Munitions rganizations, of which the following is a specification.

The invention relates to a novel bomb or grenade thrower embodying the'employment of the ordinary service rifle cartridge as a propelling agent to, discharge or throw the bomb.

Referring to the accompanying drawings of this specification:

Figure 1 represents a top View partly in section oit' the bomb thrower.

Fig. 2 is a side elevation partly in section.

Fig. 3 is a detail view to a larger scale.

Fig. 1 showsl the appearance of the cartridge after it has been tired. v

In these drawings 10 represents the central portion oi an Army rifle,'with trigger 11, channel 12 for ring pin', and'cartridge shell with-drawing pin 12X. This portion orn the mechanism need notV be particularly described as it is well known inthe art; suflice it to say that :from the point 13'to the point 111, with all the partsy inclusive, the `bomb thrower is exactly the same as a regular service rifle; locks and contiguous parts of rifles that have been damaged from one cause or another can be used for this purpose it desired; this constitutes a salvage and is of value from an economic standpoint; the rifle barrel itselfis done away with. l l

rt the point 13 is provided a screw threaded portion which interm'eshes with the thread 16 of the stock 17, which latter may be of any desired construction; as here engineered this form is suitable, by means of its end or base piece 18, for bracing the implement against the ground, or a trench wall, `or any other convenient support when the implement is to be employed. Y

As before stated the ordinary rifle barrel is eliminated, the lock case proper terminating at the point 14; screwed on to this at 19 is a casing 20 enlarged at its outer end 21 and having attached to it, as by a screw joint 22, the major bore 23 of the implement; the bomb or major missile 24: is shown in place, that is to say, in firing position in said major bore.

It will be noted that below the bomb 24 the bullet tube it side and between it andthe inner end of the major bore 23 is a chamber 25 which is inwardly continued by the smaller chamber 26,' the chambers 25 and 26 combine and constitute the explosive, and expanding, chamber for the gases of the functioned cartridge 27.

This cartridge is shown as stated at 27 and is the ordinary service cartridge of the Army rifle; the bullet or minor missile is shown at 28 and after the cartridge has functioned in the chamber 29, the said bulletpasses into the chambers 26, 25, and from thence through the major missile, or bomb, 24 as will be explained. The casing 29 is fitted into the casing 20 and forms, when the n arts are assembled, a close-litting and interlocked member; the casing 29 constitutes the explosive unit chamber or minor missile bore and it isin line with, and to the rear, o the major missile bore 23.

he manner of utilizing the explosive nature of the cartridge is through a by-pass system engineered as follows: At the point 30 is a port extending through the casing 29 and entering a channel 31. This is effected by boring through the walls of the casing 20 and their through the inner wallet' the channel 3-1 and wall of the casing29; 32 affords temporary means ot entrancev for the boring tool to properly engineer the port or opening 30; this port is disposed to the rear of the bullet 28 when the latter is positioned and the temporary entrance 32 is subsequently permanently sealed by a plug as shown. When the explosive functions in the cartridge, it will shear through the side walls of the cartridge shell and the explosive gases will effect a passage through the by-pass system that is to say, through the port 30, into the channel 3l and from thence to the chamber 25.

When the minor missile, or bullet, 28 is discharged it leaves the cartridge casing, passing' through the chamber 26 into the chamber and from this point enters the bulle-t hole of a collapsible sealer 35 and thence through theA bullet tube 36. When the bullet has entered the bullet tube the explosive gases passing through the port 30 and chamber 31 have arrived in the chamber 25 resulting in the crushing of the collapsible sealer 35. Before the bullet leaves swipes they primer 37. By referring to Fig, 3, the parts are shown yam thereby enabledfto delivera sharper inisl in position ready for firing. 'The shell or envelop 33 of the cartridge covers the port or opening 30, seals it in fact, so long as the cartridge is not functioned;Y when, how- 5 ever, the Ycartridge functions, the explosive force of the gases contained, or generated' in thecartridgefwill shear through the envelop fat., vand in,.th e xarea registering with 'the port 30, and ypermit the explosive gases 10 te enter directly into the channel vSil, and

from theiiceinto the chamber 25'; this spera- .tion` will cause the expulsion Y:of the major missile.

As will be seen from the foregoing the 1 5 minor missile or propelling `unit coordinates 'with va breech lpading'mechanism while the Amajorv :missile is--loaded from the muzzle; 'it will also be seen that the bores and the inissifles are l*centrally Ialined.
