Nov. 10, 1931. e. QUITSCHALLE SUSPENSION DEVICE FOR FIRE, EXTINGUISHERS riginal F'il ed July 7, 1927 aw-wa k E. .Il

Patented Nov. 10, 1931 UNITED STATES PATENT orr ca onone consensus; on rmxow, nnan'nnanm. GERMANY SUSPENSION DEVICE .FOR FIRE EXTINGUISHERS Original application fled July 7, 1927, Serial No; 204,080, and in Germany .Iuly 21, 1926. Divided and this application filed November 26, 1928. Serial No. 322,028.

This invention relates to a suspension device for' portable, as well as manually operable fire extinguishing apparatus and is a division of my United States application, Serial Number 204,080, filed July 7, 1927. The invention'has for its object to provide 'an' approved suspension device for fire extinguishing apparatus including a blow bolt for use, in themanual operation of the extinguisliing apparatus in combination with a bin ed member normally supportin the blow olt in inoperative position but Ee capable'of beingswung laterally to a position to permit manual depression of the blow bolt.

The invention is illustrated diagrammatically and'by way of example on. the accompanying drawings in which-the upper part" of Figure 1 shows a vertical section through the suspension device and the lower part is a side-view of an extinguishing apparatus suspended from said. device, whereas Figure 2 is a representation of a completev fire extin'guishing plant in which the extinguishing apparatus 1s suspendedfrom said suspension device. p

In Figure l'm "denotes a. vertical plate aflixed to a wall (Fig. 2) separating a room in which the extinguishing apparatus is housed from the room in which a fire could arise\ A .T-shaped member V1:. is aflixed to the wall m. The vertical part of this member is hollow and the extinguishingap aratus is suspended from' the lower half of t is hollow part, for-instance by means of. lateral pins forth from the neck of theo projectin closing cap 1 of the receptacle a and engaging suitably located and shaped slots in the lower' end of the member n. These slots are open 40 also laterally, but, here covered with a sleeve n encompassing said lower end and contacting with a packing ring- 32 provided upon the cap 7' so that the extinguishing liquid escap-- in'g eventually through the orifice 70 cannot I 46 escape at the lower end of the member n.

-I prefer to have the apparatus. carried also by a clip 11. aflixed to the wall plate m. i denotesa tubular mandrel, the upper end of which isplosed by a thin sheet-metal piece 50 s' which is inserted into a collar 8 and can be ing above the mandrel r is a blow-member M which is provided with a shank 10 en aged and normally held in raised position y an arm's hinged to the wall plate m as at 11.

If a fire should break out the fuse 2 which establishes a connection between the respective room-and the fire-extinguishing apparatus will be ignited and the ignition will be propagated to the cartridge. 16. The gas under pressure produced by the ignition of the carv tridge drivesthe mandrel 1' downby pressingforcibly and suddenly upon the'top disk 1" of the same, whereby the sheet-metal piece held by the collar s will be pierced. Instantly thereafter the gas under pressure will rush into the tubular mandrel i and act upon certain members located in the top of the vessel a which is filled with a fire extinguishing liquid surrounding a cartridge adapted to produce a gas by which said liquid will be driven upwardly into the tubular mandrel or tube 2'. The members located in the top of said vessel a are shown and described in my United States patent application concerning especiallythe fire extinguishing apparatus pro er, Serial Number 204,080, filed July 7, 192 The large amount of gas under presre now generated will force the extinguishing liquid through the tube 2' into the lower chamber of the vertical part of the T-piece n,

and then further through the pipe :19 and its branches to the sprays 1 Fig. 2, through and by which said liquid will be thrown'upon the fire and extinguish it. a, Fig. 2, denotes aside when the blow member u will be free to be knocked down upon the mandrel r '7", the efi'ect being then the same as if the cartridge t would have been exploded, in that the sheet-metal piece 8 will be pierced and the force of the blow transmitted to the tube or hollow mandrel i and further through the rod 9 of the cartridge 0, by the intermediary of the bottom of the cartridge closing member (1.

I claim: 1 A suspension for-fire extinguisher apparatus comprising a hollow member adapted to receive an extingi'luisher apparatus, a blow bolt movable in said ollow member, a hinge member engaging and normally retaining the blow bolt in inoperative osition and ada ted to swing laterally 'to release said blow bolt. In testimony whereof I aflix my signature.
