W. o. $111111. STATIONARY FIRE EXTINGUISHING APPARATUS. 110. 423,286. Patented Mar. 11, 1890.
UNITED STATES PATENT OFFICE;
WVILLIAM C. SMITH, OF NEW' HAVEN, CONNECTICUT, ASSIGNOR OF ONE- HALF TO CHARLES E. ROUNDS, OF SAME PLACE. f
STATIONARY FIRE- EXTINGUISHING APPARATUS.
SPECIFICATION forming part of Letters Patent No. 423,286, dated March 11, 1890.
Application filed February 6, 1889. Serial No. 298,883. (No model.)
To all whom it mayconcern:
Be it known that 1, WI LIAM 0. SMITH, residing at New Haven, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Stationary Fire-Extinguishing Apparatus; and I do declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying draw-' ings, which form a part of this specification.
My invention relates to an improvement in that class of stationary fire-extinguishing apparatus consisting of a series of automatic thermostatic sprinkler-heads distributed throughout a building and connected by branch pipes with a water-main common to them all, the object of the present invention being to provide means whereby any disturbance of such apparatus shall be automatically indicated at a point more or less distant from it by a predetermined signal.
With these ends in view my invention consists in certain details of construction and combinations of parts, as will be hereinafter described, and pointed out in the claims.
My invention is applicable to either dryor wet pipe systems of stationary fire-extinguishing apparatus, and may be connected with a valve or movable part aifected by the flow of 0 water located in any pipe of either system.
For the purpose of illustration I have elected to show my invention as applied to a drypipe system and utilizing the inletvalve thereof. a
In the accompanying drawings, Figure lis a view, partly in section and partly in elevation, showing the inlet-valve of a dry-pipe stationary fire n extinguishing apparatus, an automatic signal-transmitter, and connection between such valve and transmitter. Fig. 2 is a diagram showing the electric connections between several transmitters, each adapted to produce a different signal'and severally representing distinct fire extinguishing systems, with a signal-receiver, which, as herein shown, has the form of a gong. Fi 3 is a detached broken view showing the train of a transmitter such as maybe used for carrying out my invention; and Fig. 4 is a detached 0 view in elevation of a sprinkler-head, which is simply shown as a further identification of the fire-eXtinguishing apparatus.
' As herein shown, theinlet-valve A is located in a casing 13, which is interposed in the main pipe of a fire-extinguishing appa- 5'5 ratus of the type specified. A pin C, connected at one end to a frame 1), moving with the valve-stem a of the said valve so as to move therewith, projects through the casing for the entrance of its outer or free end into a small hole D, formed in a head E, located at one end of a connecting-rod F, the opposite end whereof is provided With a head G, having an elongated slot'I-I and adapted to pass through an opening I, formed in the casing .I of an automatic signal-transmitter of suitable construction. A screw K, passing through v the said elongated slot, couples the connectingrod with an oscillating stop-lever L, pivoted at its lower end within the casing J of the trans 7o mitter. The upper end of this stop normally supports the outer end of a rotative arm M, having a handle N for its manual operation, and rigidly secured. to a center shaft 0, to which is attached one end of a coiled springi7 5 P, furnishing the power for the automatic operation of ,thetransmitter. An escape-train Q, driven from the said shaft and controlled by a pallet R, (see Fig. 3,) is employed to r0- tate a make-and-break wheel S, having contact-points T projecting from its edge and normally engaged, under the closed-circuit plan herein shown, by insulated spring contact-fingers U U, connected with the mainline wires V of the circuit, which includes a battery W and a gong X If desired, the gong may be replaced by a register or supplemented by one. or replaced or supplemented by any other form of oral or visual receiver. The said battery and gong are by 0 preference located in the nearest fire-alarm station.
It will be understood that a different arrangement is adopted for the contact-points T of the make-and-break wheels S of the dif- 5 ferent transmitters, so that each transmitter, and therefore each fire extinguishing apparatus, will have a separate signal for its iden tification in the fire-alarm station or Wherever the signal-receiver may be located. Thus in T00 Fig.'2 of the drawings the transmitter numbered 4 has four contact-points arranged at equal distances apart; the transmitter n'um break the circuit three times in quick succession and then break it again after an interval. The signal sent in by these transmitters will therefore correspond to their numbers. The head E, before referred to, is connected at one end with a chain Y, passing over a pulley Z and carrying a' weight A, which will constantly pull against the pin 0 to draw the upper end of the stop-lever L out from under the rotative arm M of the transmitter. A spiral spring B, located within the transmitter and connected with the stoplever, is employed for restoring the same to its normal position and for holding it therein, the said spring being located on the opposite side of the lever from the connecting-rod F and its described attachments. The oscillating movement of the upper end of the stoplever is limited in one direction by the casing J of the transmitter and in the other direction by a stop-pin C. A knob D, mounted in the stop-lever, forms a manual device for operating the same to release the arm M of the transmitter independently of the fire-extinguishing apparatus, whereby, although the transmitter is coupled with such apparatus, it may be used independently thereof to transmit a signal. The elongation of the slot H in the head G provides for sufficient tomatic actuating devices to permit the lever to be manually operated without disturbing the coupling of the stop with the valve. When the outer end of the arm M is resting upon the'upper end of the stop-arm the coiled spring P is wound to sufiicient tension to drive the train and actuate the after which it will bestopped by an arm E and a pin F, as shown by Fig. 3 of the drawings, or in any other convenient way. To test the transmitter, the arm M is lifted by its manual device N above the stop-lever for a sufficient distance to wind the coiled spring enough more to carry the make-and-break wheel around once. If everything is all right, the signal of the particular transmitter will be sent into the receiver once mitter and the circuits is done Without disturbing the st0p-lever or its connections with the fire-extinguishing apparatus and leaves the coiled spring under sufficient tension to carry the make-and-break wheel around three times, the arm M coming back at the end of the testing operation and re-engaging with the upper end of the stop-lever.
Normally the pin 0 of the valve is entered into. the perforated head of the connectingv:rod. Normally, also, the stop-lever stands under the rotative' arm of the transmitter wherein the spring-contact fingers are engaged with a contact-point of its make-andbreak wheel through which a circuit isbe destroyed and the valve will be opened by 1 the superior pressure of water against it. As 2 the valve moves in opening it carries the pin 0 along with it and withdraws the outer end of the same from the perforation in the adjacent head of the connecting-rod, whereby such rod is left free to be moved by the weight A, which pulls it away from the transmitter and withdraws the stop-lever :from its normal position under the arm M, which has held the transmitter-train against the power of its actuating-spring, which now drives the train in, imparting three complete rotations to the make-and-break wheel,which thus repeats the signal, which it represents three times at the fire-alarm station or at any I other place where the signal-receiver may be located. It will thus be seen that no time is lost between the starting of the fire-extinguishing apparatus and the giving of an alarm identifying the apparatus started. The giving of the alarm being purely automatic and immediately responsive to the jstarting of the fire-extinguishing apparatus makes the improvement particularly valuable, especially as it is desirable in case of fire to save every minute of time. lost motion between the manual and the au- I do not limit myself to any particular type 'of fire-extinguishing apparatus or valve or movable part or transmitter, or to operating the apparatus on a closed circuit. I would therefore have it understood that I hold myf self at liberty to make such changes and alterations as fairly fall within the spirit and I scope of my invention.

If desired, any other valve or special movable part located in a pipe of a dry-pipe api paratus may be employed in place of the inlet-valve for utilizing the flow of the water to secure the motion and powerfor releasingthe i apparatus. or special part taking the form of a clappervalve might be used for the purpose.
The arm is then let go. I
