This inventionrelatesto signals, andmore particularlyto thermally operated signalsarranged to indicate an undesirable tempera# ranged to emit a continuous'audible alarmthroughout thel duration of an undesirable temperature. 'n l A further` object is to ,constructl a signal for operation by a difference in fluidpressure derived from an internal combustion'engine.
f 4Another object is" to secure an. improved controllingmeans fora signalof this type.
Other objects relating to details of construction and economies of manufacture will lows,"1s a duct 16 which turns and extends appear hereinafter. i
The invention will be better understood from the description of'one practical ,embodiment thereof illustrated in the accompanying drawings'in which, f Y
"Figure 1 1s a sectional view of a signal ap-v pliedto the radiator cap of an automobile,
kand adapted'to soundv an alarm to indicate undesired temperatures existing in the radif ator.v
Figure 2 is a side elevationpartly in section of the apparatus yof YFigure 1 taken on theline 2-'-2 thereof, and, y
Figure isi-a fragmentary view' of the valve l'shown in Figure 1 in its otherA extreme position, y .v j
The motor for operating the 'signal consists of a .base comprising a downwardlyextend ing web 1 and a flat horizontalupper head 2. Secured to the upper head is aflexible bel# lowsor diaphragm 3 which is pressed outwardly-by a coil "spring 4. 'Pivoted' to they head, as by al bracket 5 is an arm`6 which is connected to the central portion of the bellows as by the rivet and washers shown at and which carries at l,its outer end a weight 8 acting asa hammer to ring the bell, andV a depending arm 9 by which the valvemechanism to be hereinafter described is actuated. 'Thef .motor base is'supported in an inverted cupk shaped frame 10 which engages the` edgesof the head of the motor base, andY which sup# port carries upon vits upper end'a post 11 to which is secured a bell 12 by means of a screw 13 or the like, the support beingfperforated as vat .14 to allow the hammer 8 toextend therethrough and impinge upon the inner surface 'of the bell. The lower edge ofthe sup'-V portis connectedy to a ring 15 vhinged to a lower ring 16, by apivot pin 17. 4VThese partsl 1 A are adaptedv tobe mounted upon the radiator spout of an automobile in the manner of the ordinaryhinged cap.
` Extending downwardly within web 1 from the space enclosed by the head and thebelvspring returns the parts to their normal posi-l tions, causing the yhammer to impinge upon the bell and thus emit the signal desired.
Adj'acent'the opening 19 is a transverse .duct 2O extending through the vertical web and below duct 20, a duct 21 extends through theweb and an extension thereof which may be formed as shown integrally with the ring 15. This duct extendstothe bearing sur'- rounding the pivot pin, its end opens through the side of the bearing, and communicates with a duct 22 which is connected by a pipe 'or hose 23 to a source of difference of fluid pressure, for instance, the intake manifold ofthe motor ofthe car. Communication between ducts20 vand 21 is controlled by a slidevalve24, actuated by Ja th@IHOSMC` g() device, shown as a capsule 25'containing an and 21'. Thus the source fluid pressure is in is controlled by a valve 27 which consists of# communication withV duct 2O only outside of the desiredtemnerature range, Y
Communication between ducts k18 and 2O a plate pivoted at 28 and formedZ with an internal channel 29 adapted to overlie the ends ,of these two, ducts in one position. rllie movementof thevalve is limitedrby a bifurcated .end 30, the furcations. of whichv alternately engage a pinE 3:1, 'so tliatat one extreme of itsmovement/thecliannel overliesthe ends of both .ductsand at the other eXtreme the lug 32 integral, with the valvesoverlies the endv of ductg while duct, 19, is opened to theoutside air; Betweenthe fureations there is an upturnedlug', whichgis connectedby a, tensionr spring 34 to the end of armv 9.
The operationof this valve'is as follows n With the parts in position asshown in Fig-l urenl, communicatioi1A established,between ductsv 1,8, and 20and` between 2O and 2l and airA is'withdltawn by the suction., of. the yintake manifold, causing the bellowsL to `collapse and retract the hammer.y Asthishammen isre-` tracted, the directionlof thetension uponlug y 33 is changed from passing abovethe axis of;V
the pivot,as shown in Fig. 1,lto passing below the same, as shown in Eig. 3. This Lchange of'direction Acauses ,the valve ,'27 to rotateabout the pivot. (as far as permitted bythe ,pin 3l) into ytheposition vshown inFigure, in which position the end of ductl 18.V is Vopened while the endof.. duct 20 is closed. The opening ofv duct "lkrelieves the vacuum withinthe bellows and allows the spring tofexpand the same, causing the hammer to impinge upon` the bell. As lthehammer moves upwardly,
the direction o f the tension upon lug 33 passes.v
from belowvthe axis ofthe pivot to above the saidA airis, causing the valve to snap back to` its original position,this cycle being repeated-l aslong asvalve 24 remains iiil a position to keep open the communication 'between ducts 20 and 21. Thusv acontinuous audible alarm is emitted as long as temperaturesl not with#` .a inthedesired range obtain in the radiator.
`While we have described the illustrated embodiment of. our invention in some par-l ticularity, obviously many changes and variar tQls may be made therein without 'depart- .f ingfrom the spirit ofthe invention, and we,
therefore, do not limit ourselves to the precise details illustrated and described but claim as our invention all embodiments thereof coming within the scope of the appended claims.
