Patented Sept. 29, 1931 UNITED STATES PATENT OFFICE JEAN FREDERIC JULES REIBEL, F CHATELLERAULLFRANCE, ASSIGNOR T0 SOCIE I'IE DES ARMES LEWIS, OF PARIS, FRANCE, A J'OINTST'GCK GGMPANY OF FRANCE CONTRIVANCE OR DEVICE FORTHROVIING PROJECTILES OR THE'LIKE Application filed December 2a, 1928, Serial No. 329,015, and in France February 11, 1928.

The present invention has for its main object a contrivance or device for throwing projectiles or the like for any applications, but, particularly, for navigation and salvage. pur- 5 poses, as well as for throwing fireworks of any nature. V

This contrivance or apparatus may more particularly be so devised as to constitute a grappling rope thrower andcomprises in this case the combination of a tubular projectile, constructed for fitting over a guide easily adjustable in position, with means for throwing the said projectile, and with a stress-limit ing and securing system for the end of a grappling rope, suitably coiled for ofiering the minimum of resistance to unwinding.

This invention thusdefined can give rise to a large number of constructional modifications which can differ from each other:

2a (a) By the constitution and the shape of the tubular "projectile, which may be of any type whatever, and variable according to circumstances and applications. It is however specifically indicated, on the one hand, that for the application to salvage purposes, it will be necessary to devise this projectile in such a manner that it can'fioat on water and, on the other hand, that the invention, by way of new industrial product, includes in its scope a hollow projectile of this type or com prising a casing of small density forminga buoy or a float.

(b) By the constitution and the shape of the guide on which fits the projectile, and

which can also be of any kind.

(0) By the means used for ensuring the pointing of this guide, which means may be extremely variable. Thus, incase the device is used on 1and,.the guide can be provided with a simple spade bearing on the ground, the guide being orientated by hand, and, particularly in case the device is used on board a ship, the guide can be horizontally pivoted on a vertically pivoted carriage, which will carry a box in which will be coiled the grappling rope.

(d) By the means for throwing the projectile, which means can be borrowed from the energy of a compressed or-liquefied gas, or again from that of various explosives. In

this latter case, the projectile can be thrown either as the projectile of a pieceof ordnance, or as a rocket. I

(6) By the stress-limiting means securing gral with the same and struck by the mechanism of the throwing device.

These means comprise:

(a) A tube perforated with vent holes and provided with gills, secured on the distortable bottom of the firework and adapted to receive a central percussion throwing cartridge.

(6) In the particular case of the grappling rope thrower, a mortar substantially'consti tuted by an internally calibrated tube and provided, at one of its ends, with an intern ally threaded portion for screwing on thethreaded end of the grappling rope thrower, the striker of which is used for striking the cartridge of the firework when the latter is placed in the mortar.-

It is to be understood that the invention includes in its scope all the constructional modifications of the above mentioned devices, all

their modes-of execution, and all their applications.

The accompanying. drawings illustrate, by way of example only, a form of carrying out the invention.

Figure 6 shows in elevation, with partial section, an improved firework.

Figures 7 and 8 are respectively an elevation and a plan view of the tube adapted to receive the cartridge for throwing the firework.

, Figure 9 is an axial section of the mortar secured on a grappling rope throwerand con taining the firework to be thrown.

In theexample illustrated in Figs. 1 to 5, are to be found the main following members, the new combination of which forms, as stated, the main'part of the invention:

The tubular projectile 1, the bore 1 of which is closed at one end; this projectile is provided, on the side of the orifice of the bore 1, that is to say at the tail end, with lugs 1 for attaching the grappling rope. The latter thus stabilizes the projectile on its trajectory.

The guide 2 for the projectile 1, which fits over this guide; in the example illustrated, the guide 2 is horizontally pivoted at 2 on a carriage 2? which can rotate about a'vertical axis and carries a box 2 in which is coiled the grappling rope.

The means for throwing the projectile 1,

which means substantially comprise an explosive charge arranged at the end of the guide 2; and a striker 3 for determining the explosion of this charge, through the means hereinafter described.

. The striker 3 is placed at the end of the uide 2 and is held'in its rear josition by a b 7 u spring 3 interposed between the striker 3 and the stop nut 3*. A rod 3, guided in the inner bore of the guide 2, serves to actuate the striker when it receives the impulse of cock 3 movable in the tail member 3 A spring 3 is interposed between this cock 3 and the bottom of the tail member; a cocking socket 3 allows to pull the cock 3 back wards for cocking it in combination with a detent 3 sub ected to the action of the spring 3.

The cocking socket 3 is provided with a rod 3 which enters a long hole 3 1n the slide block 3 and can also enter radial slots 3" and 3, for constituting a safety device.

The stress-limiting and securing system, between the grappling rope and the projectile 1, constituted, in the example shown, by a conical coil spring 4, that is to say having a variable flexibility, so that the pull exerted on the grappling rope when the projectile starts on its trajectory should be progressive and avoids the rupture of the said grappling rope.

The grappling rope 5,'coiled in the box 2, but which might also be coiled on the ground.

The operation is as follows:

The explosive charge contained in a shortened hunting cartridge is placed in a cartridge-carrier 3, perforated with holes, which is secured at the end of the guide, or fits over the guide 2 of the projectile 1. The grappling rope 5, suitably coiled, is attached to the spring 4.

The cocking socket 36 is then slightly rotated on its axis for coming out of the slot 3*; it is then pulled backwards,.thus drawing along the cock 3 and stretching the spring 3. When opposite the slot 3, the cocking socket 3 is turned for entering the said slot, the cock 3 hooks over the detent 3 The apparatus is in the cooked position, with a safety means realized by the en.- gagenient of the rod 3 into the slot 3.

The apparatus is then suitably pointed in the direction of the objective.

The firing is eifected by bringing forward the cooking socket into the slot .3, that is to say in the firing position; then, by pressing on the detent 3 thus releasing the cock 3. The latter, pushed by the spring 3, strikes against the rod 3 which pushes the striker 3. The charge explodes and the projectile is fired, drawing along the grappling rope and carrying the end of the same to destination.

In the example of Figs. 6 to 9, the firework 6 to which are applied the improvements forming the subject-matter of the invention is of a current design having the general shape of a cylinder centrally recessed at its base for receivinga primed time cartridge 7 for the ignition of the pyrotechnical substances contained in the body of the firework when thelatter is atthe top of its trajectory.

A cup 8, made of tin plate for instance, the bottom of which is internally reinforced by a disc 9 made of a soft metal such as lead,

fits over the firework at its base and bears on the latter through the medium of a washer 10 and of a disc 11 provided with a central point 12 or striker for the primer 7 In accordance with the invention, a steel tube 13 provided with a flange 14 and gills 15 (Figs. 7 and 8) is secured through the flange on the cup 8 by means of small nails which pass through perforations l6 ofthe flange 14, discs 9 and 11 and washer 10 and enter the wooden part 17 of the firework.

The tube-13 is provided with vent holes '18 and receives a throwing cartridge which may be a hunting cartridge loaded with balistite.

The mortar is constituted by a steel tube 19 (Fig. 9) internally calibrated and fitting trally perforated for the passage of the striker.

Then the cartridge is struck, the defiagration distorts the lead disc 9 and the point 12 strikes the primer 7 of the time cartridge. The gases produced by the explosion of the cartridge escape at the same time through the vent holes and enter the mortar for driving out the firework from the latter, as well as the tube 13 and the case. The firework rises in the air whilst the time or delay cartridge burns for determinging its operation at the top of its trajectory.

The new industrial products constituted by improved fireworks are not necessarily in agreement with the example of construction illustrated in Figs. 6, 7 and 8. They may differ from each other particularly:

By the mode of action of the cartridge on the striker for the primer of time or delay cartridge.

By the constitution of the cartridge-carrying tube 13 and of the means for securing the latter on the firework. The tube might, for instance, be deprived of gills, although experience has shown that these latter are advantageous.

These new industrial products, particularly remarkable in that they are driven out from the mortar with the throwing cartridge, are, whatever may be their constructional arrangements, included in the scope of the invention.
