To a whom it may concern:

. Be a known that I, D m-111mm, of Philadelphia, in the State ofv Pennsylvania, have invented certain new and useful 7 quired to be madeof such a s stem in compliancewiththe rules of the with, so that an ational Board of'Flre Underwriters. I i

The system hereinafter described comprises an alarm-valve arranged to close an electric circuit through an electric alarm-bell whenever the sprinklers are operated, and my recorder is operatively connected theremovement of' the valve mechanism whic .suflices to operate said alarm contemporaneously effects the operation of my recorder and makes a record of such operation upon a'strip of paper or'other suitab e fabric which is continuously progressed by'a suitable clock mechanism.

The form of recorder hereinafter. described comprises a casing for the clock mechanism provided with a lock which prevents access to the record-strip and the portion of the clock mechanism which progresses it, but permits the clock mechanism-to be wound,

: set, and'regulated from the exterior of the My invention comprehends the various novel features ofconstruction and ar-' -rangment hereinafter specified and claimed.

' In the accompanying drawings, Figure I is a front elevation of a recorder conveniently embodying my improvements. Fig. 11 is a rear elevation of said recorder, showing an electric circuit including the alarm-valve of the sprinkler system. Fig. IIIis a vertical sectional view of the recorder-cas mg the electric recording mechanism lnclosed therein; I In said figures, 1 is'therecorder-casing,

a which comprises the chamber 2, containing the recording. mechanism, and the chamber 3, in which therecord-stripis stored. Said chamber 2 is provided withthe door 5, which is bin ed to the casing 1 at 6 and'provided with t ejlock 8. 1 a

The clock 10 is fixed in theficasing 1 with show-- to close said circuit 42 by'the ravens whe' Patented March 26, 1.907

its winding-spindle 11 and, setting-spindle accessible from the rear of the cas'inggas i dicated in II. The rearwardlyrejects", ing portion of said "clock is @Qflhtmfin casing members 14 .15, and, as'indicated dotted lines in Fig. 1 theicasing ma'lnli ,{6o

permit of the re lation'offthe cloc mechf j anism without giving access to ,the, chamber 2,containing the recordin mechanism. ,1

The clock-face 18 projects through the door 5, as-indicated'in'FigJLfand is su ported in fixed relation with" the casing 1 f y the standards 20. 't The arbor 22 of the hour-handof the clock is conveniently provided with a rubber facing: or sleeve 24, 'opposed by the roller '25, mounted u on thespring' 2.6, andthe recordstrip 28, W h is primarily wound in a roll mounted upon the stud 30, extends between said sleeve 24 and roller 25 and is continu ously progressed in the direction indicated, by the arrow by the .rojt'ation' 'of the clock mechanism. Said s't'rip 28is embraoedvb the frame 32, in which [the lunger 331s mounted for reci rocat'zion'wit its ointed 11 per end normal y withdrawn from t e path o the strip by the sprin 34. f As shown in plunger 33 against thesti'ess "'of the spring '34 f a v of the armature 38.

As indicated in Fig.-'II,1,the electroma' etgg'o 40 ls'incl'udedin the circuit 42'w1th the' '5 and perforates the strip '28 at each vibration i tery 43 in parallel relationwithithe alafiiiibell 44', the arrangement beingjsuch that bration of the armature 4b" of said b p m serves to make andb'reak thecircuit thr gh the magnet 40 and-puncture therecord-stri f 28, and thus record the o eration of said bel Said circuit 42 includest e alarm-valve ifiof the sprinkler'system, which valieis arrang' the valve-flap 50 is moved the? direction? of the: arrow marked thereon: 1 It is understood. that the aforesaid movement the alarm-valve is dccasionedby'thegflow water "therethrough whenever any sprinkle inthe system is operated; W The rules of .the-NationalyBoard *of Fire" '15 maybe upturned upon litslhingpiil fiv toil Underwriters, above referred to provide that 7 every automatic sprinkler system shall be I obstructing the how of fluid in said tested daily by closing the circuit through the alarm-valve circuit, and it is to be noted that such closure of the circuit 42 (indicated in Fig. II) efl'ects the operation of the alarmbell 44 and contemporaneously records the vibration thereof by puncturing the strip 28.

The device above described is operated as follows: A quantity of the recording-strip 28 suiiicient to last any required length of time is mounted upon'the stud 30 within the chamber 2 and the latter closed and secured with the lock 8. The clock 10 being maintained in operation, each test of the sprinkler system or the alarm-circuit thereof is recorded upon the strip 28 by the imprinting or perforating action of the plunger 33,- and the record-strip is continuously progressed and deposited within the chamber 3, awaitir' a; the visit of the inspector representing the Board of Fire Underwriters, who alone is provided with a keylto the lock 8. At any desired intervals said inspector may open the door 5, withdraw the perforated strip 28 from the chamber 3, and note the record of tests made thereon.

I do not desireto limit myself to the precine ails elf-construction herein set forth, it is obvious that various modifications may be made therein without departing from the essential features of my invention.

1. The combination with an automatic sprinkler system including a valve normally obstructing the flow of fluid in said system; of a recording device, comprising mechanism arranged to chronologically progress a record-strip; a plunger arranged to imprint said strip; a spring arranged to normally retract said plungervfrom the path of said strip; an electromagnet an armature for said magnet distinct from said plunger, arranged to operate said plung'erto imprint said strip; an electric circuit connecting said valve with said electromagnet an electric signaling device comprising an electromagnet bridged across said circuit in parallel relation with the electromagnet of said recording device; an armature for said magnet of the signaling device; a battery in said circuit between said bridge and said valve; whereby when said circuit is closed by said valve, said signaling device contemporaneously interrupts the circuit leading to said recording device and produces anaudible signal; a casing comprising two chambers, one inclosing said recording mechanism and the other arranged to receive the imprinted portion of said strip; and, means normally maintaining closed, the chamber containing said recording mechanism said chamber for the imprinted portion of the strip being normally accessible, substantially as set forth.
