Hammell and Frederick K. Comiskey,
Detroit, Mich., assignors to Eureka Williams Corporation, a corporation of Michigan ApplicationFebruary 19, 1945, Serial No. 578,716 2 Claims. (Cl. IGZ-37.6)
This invention relates to dischargers and particularly to an expendable.self-contained signal discharger and flare.
Cllrincipal objects of the invention are to prov1 e: A
A new and improved form of signal discharger;
A newand improved form of expendable, selfcontained signal discharger and are;
A simple. and inexpensive, but efficient, construction for a self-contained signal discharger and flare.
Other and further objects of the invention will be apparent from the following description and claims and will be understood by reference to the accompanying drawings, of which there is one sheet, which, by way of illustration, show preerred embodiments and the principles thereof and what we now consider to be the best mode in which we have contemplated applying those principles. Other embodiments of the invention embodying the same -or equivalent principles may be used and structural changes may be made as desired by those skilled in the art without departing from the present invention and the purview of the appended claims. W-e also contemplate that of the several different features of our invention, certain ones thereof may be advantageously employed in some applications separate and apart from the remainder of the features.
In the drawings Fig. 1 is a longitudinal sectional view of a device embodying one form of the invention:
Fig. 2 is a cross section taken along the line 2-2 of Fig. 1; and
Fig. 3 is a longitudinal sectional view of a modified form of the invention.
As illustrated in Figs. 1 and 2, the device comprises a tubular member I having an internal bore I2 and forming the case of the flare projectle as well as the barrel of the discharger therefor. One end of the member I0 is closed by relatively heavy integral walls to denne a chamber I4 for accommodating an expelling charge of explosive IB, the rear wall I8 of the chamber being apertured to receive and retain a primer or detonator 2D for the charge I6. The front of the powder chamber is closed by paper and felt washers 22 and 24 respectively, through which a fuse 26 extends from the powder charge I6 to the nare' projectile 23, the fuse 26 being connected to the projectile 2B and related thereto so as to ignite the flare projectile after the same has been expelled from the discharger by the explosion of the charge I6.
The outer periphery of the wall defining the powder chamber I4 is formed to provide a continuous groove 30. A cup-shaped metal stamping 32 is formed to telescopically receive the closed end of the member I0 and is provided with a plurality of inwardly and rearwardly extending prongs 34 projecting` into the groove 33 and cooperable with the rear wall thereof for securing the cup-shaped member 32 to the member I0. The resilience of the material of which the cup-V shaped member 32 is formed makes it possible to slip the cup-shaped member on over the end of the member I0, at which time the prongs will yieldand thereafter snap into the groove 30 for securing the member '32 relative to the member I0.
The cup-shaped member 32 has a firing pin 36 suitably mounted therein and positioned to engage the exposed end of the detonator 20 when a sharp blow is imparted to the member 32 in a direction toward the member I0 for firing the charge I6. A spring 38 is operatively positioned between the bottom of the member 32 and the outer face of the end wall I8 of the member I0 for yieldingly maintaining the same separated.
A safety comprising an interrupted spring coil 40 having one end 42 projecting inwardly through an opening in the member 32 and bearing against the end wall I8 normally functions to prevent accidental firing of the device. A tape 44 carried by the spring 40 is provided for conveniently removing the end 42 from its obstructing position as illustrated so as to permit the firing of the discharger.
The projectile 28 is positioned in the bore I2 of the member I0 in such a way as to be expelled therefrom upon firing of the charge I6. Suitable disks 46 of paper, cork or other suitable material frictionally fitted in the open end of the bore I2 are provided for holding the projectile 28 in thel bore I2 of the member Il! until the firing of the charge I6.
In the embodiment illustrated in Fig. 3, the construction is much the same as that illustrated in Figs. l and 2 except that the tubular member H0 is formed by a piece of tubing in the rear end of which is positioned a standard 10gauge shell II2, the rim II4 of which seats on the end of the tubular member IIB. The cap IIB of the shell is pressed into the tube so as to be secured therein. The projectile IIB in this case is confined within the paper shell |23 of the shell II2. provided witha groove 30 in which the tabs project The tubular member I I0 is |38 similar to the groove or prongs 34 of the cup-shaped shell 32 selves ofsueh changes and alterations which fail within the purview of the following claims.
We claim:
1. A discharger for signals and the like comprising a tubular member having a bore closed at one end thereof, said tubular member having an exterior peripheral grooveat the closed vend thereof, a cup-shaped stamped metal merriberk telescopically and slidably associated with the grooved end of said tubular member and having integral inwardly extending springs in the form of prongs projecting into said groove for securing said members against sliding movement inone direction while `permitting sliding movementin theother vdirection relative to one another and w'i't'nthe closed end of said tubular member ispacec'l` from the bottom of said cup-shaped member, said cup-shaped member mounting a ir'ing ypin in said space `and saidtubularmember having" an explosive charge and a detonator therefor positioned to be struck by saidffirin'g `pin uponfaotuation thereof occasioned by rapid movementor said cup-shaped member in said other di-A rection relative v'to said tubular member.
2. A discharger for signals and theiike 'comprising atubular member having a, Abore closed atonesend thereof, 'said tubular-l'memberf'haiving an external shoulder means at the closed end thereof, a cup-shaped stamped metal member telescopicaliy and slidably associated with the closed end of said tubular member and having integral inwardly extending prongs engageable with said shoulder means for securing said members against sliding movement in one direction While permitting sliding'movement in the other direction 'relative -rto one another and with the closed end of said tubular member spaced from the bottom of said cup-shaped member, said cupshaped member mounting a firing pin and said tubular member having an explosive charge and adetonator therefor positioned to be struck by said ring Vpin upon actuation thereof occasioned by rapid movement of said cup-shaped member in said other direction relative to said tubular member.
