IMPROVEMENT IN BLASTING-CARTRIDGES.

Specification forming part of Letters Patent No. 152,053, dated June 16, 1874 application filed February 20, 1874. I 1

To all whom it may concern:

Be it known that I, 'J'ULIUs H. STRIEDING- ER, of New York, in the county of New York and State of New York, have invented a new and Improved Cartridge for Destroying Buildings, of which the following is a specification:

The object of this invention is -to facilitate the destruction of buildings in populated cities and towns during extensive conflagrations, to enable the fire department to arrest the progress of thefiames in case of danger to other structures; and the invention consists in the construction of a new cartridge, which, when placed against the walls of the buildings to be destroyed, and exploded, will secure the desired result without danger to other buildings, or to the attending firemen or other persons. The cartridge is made with perforated ends, and provided with means for connecting several of these cartridges together lengthwise, so that they may be strung along or around the sides of buildings to simultaneously affect the same."

The chief peculiarity of the invention is the placing the cartridge alongside of a wall, when heretofore it was always deemed necessary to cause the explosive material before it was ignited to enter into the matter which was to be disintegrated by the powder or explosive material; but I find that by placing a properly-constructed cartridge, whose shell is made of pasteboard or paper, or other harmless material, against the wall, it will affect such wall in the proper mannerthat is, destroyer crumble itwithout affecting inj uriously any 1uatter with which it is not in absolute contact.

In the accompanying drawing, Figure 1 represents an elevation ofa building along I which my system of cartridges is shown to be extended. Fig. 2 is a face .view, partly'in section, of a series of my improved cartridges connected together.

Similar letters of reference indicate corresponding parts in both figures.

The letter A in the drawing represents my new cartridge. The same is made of cylindrical or other suitable form, of pasteboard, paper, or other such material that will, when exploded, not be apt to injure by its own contact any matter against which it may be propelled. The ends of'this cartridge are made with central perforations, one end, a, being merely perforated, and the other end, 1), constructed with a projecting tube, d. e e are hooks or eyes, which are fastened to the outside of the cartridge, preferably to its heads, to facilitate the proper suspension of the cartridge where it may be required, and also to permit the tying together of a series of adjoining cartridges. Whenever it is found inconvenient to place one of thesecartridges on the ground, I prefer to suspend it by the hooks or rings 00, or by a string thatis fastened to such hooks or rings, in the manner indicated in Fig. 1, although the cartridge will be as effective if-placcd on the ground against the front or side of the building to be destroyed. For the purpose of destroying a house or a large portion thereof, it may often be necessary to use a series of cartridges of my invention, and in this case I fit such series of cartridges together by entering the projecting tube at of one cartridge into the aperture of the head a of the next cartridge, as indicated on the left-hand side of Fig. 2; but between windows and doors, whercnothing could be efl'ected by placing the cartridges, I connect the string of cartridges used by rubber or other tubes f, in the manner indicated in the middle of Fig.2, the tube f being inserted into or drawn over the projection d of one cartridge, and inserted into the perforation a of the next, such tubef extending across. or under the windows and doors, in the manner indicated in Fig. 1.

The cartridges are filled witlrpowder, ni-

tro-glyccrine, giant-powder, or other powerful explosive agent, and the tubes f, if used, are also filled with explosive or highly inflamma ble material. A small vent, g, is or may also be formed in each cartridge, for the purpose of facilitating the ignition of the contents by means of an explodcr. If a series of cartridges tlnisconstrueted are strung along the face of the building in the manner shown in Fig.- 1, and the content-sot one of the cartridges are ignited by-applying a suitable fuse to the vent 1 thereof, then the fire will, by the connections f and d, which are all filled with powder or inflammable or highly explosive material, be

immediately communicated tot-he whole series or string of cartridges, and the explosion will take place practically simultaneously throughout the whole length of the cartridges employed. The effect will be that the walls against which the cartridges are placed will be destroyed by the latter, the power of the explosive agent carrying the ruins or dbris inward, thus protecting attendants, firemen, &c., from danger of injury by the explosion.

But 1 do not intend to confine my invention to the blowing up of buildings only, as it may be used with equal efiect on rocks, vreoks, and for other purposes.

I claim as my invention- The combination of the flexible tub'cf with two cartridges, A A, that have perforated ends and hooks or eyes 0 a, substantially in the manner described.

JULIUS II. STRIEDINGER.
