GAS-CONTROLIJ-ING APPARTS.

Application filed April 22, 1910. Serial No. 557.043.

lil/ly invention relates to improvements in gas-controllingapparatus, and my object is to r'ivitle newl and novel apparatus Whereby the supply of gas or 'other liuid entering a building through the service-pipe thereof, may be readily out ofi in luse of fire, or at any other time desired.

The apparatus embodies a self-closing velye for controlling the flow of fluid through the service-rupe, manually-operable ineens whereby said valve may be controlled at 'a point distantI therefrom, 'and fusible incanswhich when subjected to a predetermined degree of heat will melt and permit the valve to automatically close,

ln order that the invention may b'e fully understood, reference Will now be made to the accompanying drawings in which: l

Fiagure l is i side elevation partly in section of iny improved apparatus. Fig. 2 is n detail vertical section on line H-ll of l.r Fig. 3 is a section on line IIL-HI 2, with a portion of a conduit added. is a Central vertical section ot' the uw.: on line .iV-lV of l. Fig', 5 is a detail perspective of a bracket employed (l and 7 are horizontal sections on lines .fb-VI and Vif" -J/'L respectively, of Fig. l. Fig. i f a iront 'elevation ol" aber; employed in carrying out the invention. Fig. S) is an end view of un adjustable elbow 'employed in cau'rvine out the invention.

l designates a service-pipe for conducting Afluid from the main (not shown) into a building, the iront wall Qvof which only is Shown.

3 designates a valve for controlling the How oi fluid into the building through the service-pipe l. baid val ve consists ot" a shell il; having a port 5 for the 1'nxssuge of the liu i x sliding-gate (S for closing' said port.

Yseat 18 clean ot any is provided at its lower end with tubular guide l0, closed by a screw-cap ll, and adapted `to receive 'the lower cud stem 7 as the saine approaches the end ward stroke. rlhe upper portion et has a stutlingbox l2 through which the stein 7 extends and. said upper portion has. riso, a pair oi oppositely-extendingr. diametrically-opposed arms to carry a bracket 1L. Gate 6 is provided with lug; proviecting therefrom and having a beveled side lo lfor engaging a correspon-dir beveled portion 17 of the stein which n lie valve cloaes pushes the gate firmly :n iinst it.V rat l5. the valve-sten@ being breve t inde lltrom springing baci; onder the r "ure exerted by its beveled portion l might interfere 'with I gate. Spring S is assisted. 1n closing; l by a lever 19 ont. a Weight 53C. ,vli

latter is adjustably'socured to the treo end ot the Q1 und .a stt-Screw Q2.

' f and.

`7 bracket upon arnls lil smid bracket may he turned to face the tubulnr extensions in` almost any direction. 'to receive the lower ends of a pair ot conduits 325,

34; designates a nut having a thread 35 extending' into a spiral .Groove in the uilper enlarged portion or stein 7. to actuele said stem as \\ill'l1e1einafter appear.

3l isconnected by o fusible substance l to the hub 37 ol a sprocket-wheel 35%,. which extends between the diametricallybpnosed bifurcated portions L. und i ald thereby from xf'ertical n'wrcmc t 'l :ich the Nut vided with a handle 45 whereby it and the conduits' 33, and attached at their adapted to abut against a staple '53er a' upper ends to a similartape 43 extending halt-way around a sprocket-wheel 44,'A promay be actuated. Sprocket-wheel 44' is mounted-v upon a Ashaft 46 j ournaled in a box 47 pro-` vided. with a hinged door 48, so that access,l

may be had'to the handle 45 `forthe purpose of turning sprocket-Wheel 38 to manually,

close the valve. Door 48 is provided with a staple 49 to receive the slotted end of a hasp 5G loosely secured to theuppr side of 'the box, so that its` slottednd may be placed in position over staple 49, and se cured by a padlock 5 1, to prevent irrespon-y :sible persons fron'i gaining access to handle scrlbed, a'f'se'rviee-pipe 'for conducting fluid y4 5 to tamper with the same. Tamp'ering, with handle-'45, is further guarded' against by providing the saine withfa Astaple 52 "staple 54 in the box, and be locked in engagement therewith by a padlock 55. Door 48 has grooves 56 therein, to weaken the' same, so that; access, may be readily `had-to handle infcasebf door, after which either of the staples thioughavhich the hasp of lock 55 extends, may be'brolcen to 'release the handle '45. Sprocket-wheel 441` is 'of greater diameter than sprocket-wheel 38, so that the latter will be turned one revolution by turning the iornier about t\vo-th1rds of 'a revolution, or

suiiiciently to swing handle '45 from staple 52 to staple 54, as one revolution of sprocket-` wheel 38 is neccssary'to close valve 3v .when the parts are made in about the proportions shown in the drawings. l

Cables 42 which consist preferablyof fire- 'fprooi' material are further protected r`bythe conduits 33, which latter have adjustable elbows 57 so that they may be extended lin any desired direction. Elbows 57 consistof adjustable , sections 58 and 59, which are pivotally connected by bolts 60, carrying grcoved rollers v6l to guide the cables 42 through then conduits.

In practice, the valve is held in the open' position shown in Fig. l by nut 34. Should a fire occur in the building, or should it be desirable for any reason to cut-oit' the flow.

el u'id through the service-pipe 1, any au'- thorizcd person can promptly perform this operation by opening the box 47, lgrasping handle 45, and swinging -it around until stopped bythe staple 54. This movement of the handle rotates wheel 38 and causes i1- thr'gh the intermedi-cy l 4 Parts 2 death@ valve. 'Should ai@ fusibie :would nut 34 `from wheell38, and .permitspri'ng 8,' lever19, and weight 20 tov voriginal p a fire by breaking saidj v1,033,9ise

iv connecting vsubstance f 35 become heated to "the melting pointfbefore thefrewas discovered,l i

thus automatically close the valve. After the yfire had .been extinguished4 and the fusible substance -36 bet-Ween nut 34 and wheel 38 hadr been renewed, the valve could lbe opened bymoving handle 45 back to its 'osition or until its Staple 52 contacted with staple 53. l WVhile I, have shown-the preferred form ro'f my invention, I, of course, 'do notllirhit .myself tothe exact construction and arrangementfof parts as shown and described, as it is obvious that changes can be made without departing from the spirit or scope ofl the appended claims.

` Having thus described my invention, what I I claim is:kv :p

1. -In an apparatus ofthe character deintol a` building, a valve to control the flow' lf-fluidthroughsaidpipe, a Wheel on said 'valve toopen and close the same, means extending' at'a distance from' said wheel for turning the same in either direetiom conduits for. protecting said means, and a bracket adjustably-secured tothe valve, said 'bracketV having tubular portions to communicate with ,the oonduitsand bifurcated portions to prevent lateral movement of the wheel.

*12. In an apparatus ofjthevcharactcr de# scribed, a service-pipe for conducting iluid into a building, a valve tocontrol'the flow 'ofiluid through said pipe, manually-operable means extending ata distance from :said'valve to close the same, a'box inclosing that portion of said means most remote' from the valve, said box havin-g a grooved nreakable portion, and means for 'locking said box in closed position;

3. In an apparatus of the character described, a service-'pipe .for conducting fluid into a building, a valve to control the`,ilo;1sr

vrof fluid `'through said pipe, said'valve having a spiral groove, a nut engaging the groovedportion of said valve to open or close the same, a wheel for actuating said nut, and a bracketfloosely engaging opposite sides ofsaid wheel to prevent the same from moving in any other than Aa rotary direction.

In` testimony whereof I aiiix my signature, in the presence ot two witnesses.
