S. WILEY HOLDER FOR PYROTECHNIC CARTRIDGES Filed Dec. 30, 1930 INVENTOR. Eamuel Wi 1E BY 17 W ATTORNEY Patented Feb. 16, 1932 SAMUEL WILEY, OF METUCHEN', NEW JERSEY HOLDER FOR PYROTECHNIC CARTRIDGES Application filed December 30, 1980. SerialNo. 505,574.

(GRANTED UNDER THE ACT OF MARCH 3, 1883, AS AMENDED APRIL 30, 1928; 370 G. 757) The invention described herein may be manufactured and used by or for the Government for governmental purposes, without the payment to me of any royalty thereon.

This invention relates to a holder for pyrotechnic cartridges.

In discharging signal cartridges the usual practice consists in placing the cartridge in the barrel of a pistol which contains a conventional firing mechanism. The pistol can only be employed, however, with cartridges of limited size and moderate propellant charge.

The principal object of the present invention is to provide a holder for supporting a large cartridge carrying a heavy propellant charge. Inasmuch as the holder is primarily intended to be carried by aircraft and in proximity to the seat of an occupant a primary consideration in its design has been minimum size and weight. While fulfilling these requirements the present holder is arranged to be adjusted for varying angles of departure, and to permit the operations of mounting and removing the cartridge to be conveniently performed with one hand.

With the foregoing and other objects in View, the invention resides in the novel arrangement and combination of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

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

Fig. 1 is a view in side elevation of the im- 1 proved holder with a cartridge carried there- Fig. 2 is a view in front elevation of the holder;

Fig. 3 is a plan view thereof;

Fig. 4 is a detail longitudinal sectional view shawing the plunger in position for loading; an

Fig. 5 is a view similar to Fig. 4 and showing the plunger in retracted or unloaded position.

Referring to Figs. '2 and 3 the holder comprises a frame including spaced side plates 6 having a flange 7 for receiving a bolt 8 passing through a support member 9 which in the case of aircraft would be the rail surrounding the cockpit. The side plates are preferably connected at their lower extremities by a bar 10 which accurately spaces them and insures their'parallel relationship.

The side plates'fiare provided with aligned apertures 11 constituting bearings for receiving the trunnions 12of a cradle 13 fitting between the "side plates. For purposes of assembly the trunnions'are eachinserted in a socket 14 of the cradle and are conveniently secured thereto by a screw 15.

One of the trunnions is provided with an annular head lfi'positioned externally of the side plate and having peripheral notches or recesses 17 for receiving a lug 18 on a spring 19. The lower end of the spring is secured by a screw 20to a block or projection 21 on the side plate while the upper end of the spring extends through an aperture 22 in the flange 7. The recesses 17 and the lug 18 are complementarily inclined to enable the lug to be cammed out of engagement when pressure is applied to rotate the cradle.

Referring to Figs. 4: and 5 the cradle 13 is essentially a tubular member in which is mounted a bolt 23 of greater length than the cradle. The upper or head portion 24 of the bolt adapted to fit in the socket 25 of the cartridge 26 has a sliding fit in the tube while the reduced stem 27 is embraced by a spring ranged to engage in the annular groove 36 of the cartridge when the cartridge is placed on the bolt and rests against the annular head 37 of the cradle. i I

The bolt is normally retained in the re tracted or unloaded position shown in Fig.

5, both to protect the portion 24 and to prevent interference with the operator. Rotation of the bolt to position the pin 31 in the slot 32 Will enable the spring to come into play and move the bolt forward to the position shown in Fig. 4: Where it is rigidly held upon being rotated to engage the pin 31 in the offset. The cartridge may noWbe placed on the bolt Where it is securely held. by-the catch 34. The cartridge serves as a barrel and carries a firing mechanism 38,.p-being'i'n the present instance a friction igniter, for setting off the propellant charge 39 to project the signal or pyrotechnic charge 40. The

emptycartridge case is ejected by merely 'rehead of the bolt, a pin carriedby the bolt,

and a guidewaywithoffset terminals in the cradle for recivi-ng the pin and limiting movement of the bolt.

2. In a cartridge holder, a frame including side plates, a cradle trnnnioned inthe side plates, means for holding the cradle in position of angular adjustment, a bolt of greater length than the cradle and reciprocal therein, a spring latch in the head of the belt, a; spring normallytending to extrude the head of the bolt, a pin carried by the bolt, and a guide-Way in the cradle for receiving the pin and limiting movement of the-bolt.

3. In a cartridge holder, a support, a cradle trunnioned in the support, means for holding the cradle in position of angular adjustment,

bolt mounted in the cradle for limited reciprocal movement, a spring latch in one end of the bolt, a spring normally tending-to extrude the latch end of the bolt, and means for rigidly connecting the bolt to the cradle at the limits of its stroke.

4. In a. cartridge holder, a support, a cradle trunnioned in the support, a bolt mounted in the cradle for limited reciprocal movement, a spring latch in one end of the belt, a spring normally tending to extrude the latch end ofthe bolt and means for rigidly connecting the bolt tothe cradle at the limits of its.:stroke. 5..)In a cartridge holder, a casing, a bolt in the casing movablelongitudinally to project from one end of the casing, means on said projecting-endoi the belt for holdinga cartridge, and means for rigidly securing the boltto the casing at the limits'of its longitudinal movement. a r
