v SAFETY ATTACHMENT FOR CAR-STOVES.

SPECIFICATION forming part of Letters Patent No. 371,350, dated October 11, 1887.

Application filed March 18, 1837. Serial No. 231,406.

To ctZZ whom it may concern.-

Be it known that I, GEORGE A. OGLE, of Baltimore, in the State of Maryland, have invented a new and Improved Safety Attachment for Car-Stoves, of which the following is a full, clear, and exact description.

This invention relates to fire-extinguishing attachments for car stoves, the parts being so arranged that when subjected to a powerful shock orjar the ball or weight will be dislodged and will fall upon a receptacle containing chemicals, which,when freed,will flow to the tire, there to generate ammoniacal vapor or carbonic acid gas, wherebythe the will be immediately extinguished.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.

Figure l is a central sectional elevation of my improved fire-extinguishing attachment for car-stoves, a portion of the stove-body being shown in section. Fig. 2 is a sectional plan view taken'on line :0 0c of Fig. 1, and Fig.

3 is a detail view illustrating the construction of the flanges of the telescopically-connected tubes constituting a portion of the attachment.

In the drawings,'10 represents a stove-body, of which the fire-pot is shown at 11, the grate at 12, and the ash-pit at 13. Two or more outwardly-extending tubes, 14, are connected with the stove-body, preferably upon opposite sides thereof, the tubes being arranged for communication with the fire-pot of the stove by way of fines 2, as clearly shown.

The tubes 14 are each provided with telescopically- united sections 15 and 16, the interlocking flanges of the sections 15 and 16 being shown at 3 and 4 and arranged so that by giving the section 16 a quarter-turn it may be removed from the section 15, but so that the two sections will be held together when their flanges are thrown into register.

Vertical tubes 17 extend upward from the tubes 14, the bores of the tubes 17 and 14 communicating, and at a point near the upper end of each of the tubes 17 there is formed a socket, 18, adapted to receive and hold a heavy metallic ball, 19, the sockets being so (No model.)

proportioned that the balls will not fall therefrom except when the car is subjected to a heavy jar. The upper ends of the tubes 17 are covered with perforated caps 20, which serve to ventilate the tubes 14, additional ventilation of said tubes being provided for through the medium of short tubes 21, which lead upward therefrom, said tubes 21 being provided with perforated caps 22, as illustrated.

Within the tubes 14 there are placed receptacles 30, which contain the chemicals by which the ammoniacal vapor or carbonic-acid gas is produced, the receptacles being preferably made of any fragile material-such as glass-which will be broken by the fall of the balls 19 or by the collapsing of the telescopic sections 15 and 16 when said sections are subjected to a strain such as that resulting from the telescoping of the car. In order that the receptacles 30 may be protected from the heat, and at the same time from any excessive rattling, I line the tubes 14 with asbestus packing, as shown at 6.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. The combination, with a stove, of tubes arranged in connection therewith and adapted to IBCtiVB chemical-holding flasks and communicating with the fire-pot thereof, upwardly extending tubes leading from the firstnamed tubes, and weights held in sockets formed at the upper portion of said tubes, substantially as described.

2. The combination, with a stove, of pipes 14, having telescopically-connccted sections 15 and 16, tubes 17, extending upward from the pipes 14, connecting with the fire-pot of the stove, the tubes 17 being provided with sockets 1S, and weights held by the sockets, substantially as described.

3. The combination, with a stove, of tubes 14, provided with ventilating-tubes 21 and arranged to communicate with the fire-pot of 5 ICC 4:. The combination, with a stove, of tubes arranged to communicate with its fire-pot, ventilating-fines arranged in connection with said tubes, an asbestus packing or lining fixed 5 within the tubes, chemical-receptacles carried by the tubes, and weights for crushing said receptacles when the stove is subjected to any undue shock or jar, substantially as described.
