Specification of Letters Patent.

Patented Apr. v2, 191s.

Application filed July 24, 1917. Serial No. 182,469.

To all whom it may concern:

Be it known that 1, MICHAEL E. CUDDY, a citizen of the United States, residing at lVaterville, in the county of Kennebec and State of Maine, have invented new and useful Improvements in F ire-Extinguishers, of which the following is a specification.

This invention relates to fire extinguishers, and comprehends a stationary system where by damage resultant from chimney fires may be avoided.

More specifically stated the invention comprehends the provision of a perforated discharge pipe adapted to intersect the smoke passage of the chimney, and which pipe communicates with the supply pipe of the water system, or a pipe leading from some other suitable source of supply.

The nature and advantages of the invention will be better understood when the following detail description is read in connection with the accompanying drawing, the invention residing in the construction, combination and arrangement of parts as claimed.

In the drawing forming part of this specification like numerals of reference indicate similar parts in the several views and wherem:-

Figure l is a vertical sectional view through the chimney showing the invention applied thereto.

Fig. 2 is a fragmentary enlarged sectional view through the extinguisher.

Referring to the drawing in detail A indicates the chimney, one wall of which is provided with an opening 10 to receive a cast iron cylinder or sleeve 11. The cylinder is of a length equal to the thickness of the wall in which it is embedded, and is closed at one end except for a restricted centrally disposed opening 12. Disposed adjacent the opposite or open end of the cylinder are internal lugs 13 adapted to be engaged by cooperating lugs 14 projecting from the closure 15 for the open end of the cylinder. The closure cap 15 is provided with a central opening disposed in axial alinement with the opening 12 in the opposite end of the cylinder, and passed through this pair of openings is a pipe 17 which projects beyond both ends of the cylinder, one terminal of the pipe intersecting the smoke passage of the chimney or flue A and perforated as at 18 for the purpose to be presently set forth. This extremity of the pipe is closed by means of a plug 19 which is threaded: within the open end of the pipe as shown.

The opposite end of the pipe" 17 is-dis posed exteriorly of the chimney A, and is connected to the offset branch 20 of the T- coupling 21. One extremity of the coupling has associated therewith a short length of pipe 22, which in turn is connected by any well known form of coupling or union 23, with a water supply pipe 24 which communicates with the running water system of the building. Associated with the pipe 24 at an appropriate point, is a valve 25 which controls the passage of water through the pipe 24 into the nozzle or pipe 17. In order to prevent chimney fires, when indications of the same are evident, it is only necessary to open the valve 25, when water from the running system of the building, will pass through the pipe 241 into the discharge pipe 17 and subsequently spread against the walls of the chimney through the perforations 18.

Associated with the opposite end of the coupling 21 is a short length of pipe 26 which in turn is connected with a water supply pipe 27 through the instrumentality of a coupling 28 of any suitable construction. The pipe 27 leads from a water supply tank 29 which is arranged at any convenient location, it being understood that the tank 29 is employed only when running water is not available. A valve 30 is arranged within the pipe 27 at a suitable point in its length, the valve controlling the discharge of water from the tank 29 and to the nozzle or pipe 17. It will be noted that by reason of the construction and arrangement of parts, that by closing the valves 25 and 30, and uncoupling the unions 28 and 28, the nozzle may be removed from the chimney for cleaning.

While it is believed that from the foregoing description the nature and advantages of the invention will be readily apparent I desire to have it understood that I do not limit myself'to the exact construction and arrangement of parts herein shown, and that such changes may be resortedto when desired as fall within the scope of What is claimed.

What is claimed is 1. The combination with a support having an opening therein, of a sleeve having a length equal to the thickness of said support and wholly disposed within said opening,

2. The combination with a support having an opening therein, of a sleeve Wholly, disposed Within said opening, sald sleeve being open at one end except for a restrlcted censleeve adjacent its open end; a closure for said open end said closure being adapted to engage against one side of said lugs, fingers projecting from said closure and having offset terminals adapted to engage the-opposite side of said lugs, and said closure having a bore disposed in alinement with said aper-- ture.

In testimony whereof I affix my signature.

10 tral aperture, internal lugs formed on said MICHAEL E. CUDDY.
