July 27, 1943. c. F. YosT FIRE EXTINGUISHING APPARATUS Filed May 8, 1940 /Nww www. NW www,

Patented July 27, 1943 y This `invention `relates' toflre apparatus of the portable type and, more particularly to vthe motor type', of engine in which the pumping apparatus svactivated from theengine ofthe truck.

In the majority of instances, the `(attent of the fire is such that the immediately available supply of water will be sufficient to extingush it promptly andwith little damage to the premises. With the' ordinary apparatus-it is "necessary to employ for such hres either'jagchernical apparatus or to end a plurality,ofciiecigivalvd inrets r5.1 Leading from eaeumanifoiatc the banal t is a valved inlety pipe I6, and, associated With the tank are low and'l'iighpressure pumps'l'l and I`8 respecrs in corrrmumqauon withfmelmterier'ef tank connect ythe vrire 4apparatus with Va hydrant o1- u other sourceof water, before'an'y supplycan oe had at the fir e, `ths,l 4in manycases', resulting delay 4and consquent; g'rov'vth of a I niuor emilia-f gration to one ormajor proportions;

important object ,of the present is to'provide af re apparatus including' afstruc#` y ture such that a supply of Water is immer iiatelyy available, and Without attachment ci thev appa-- ratus to a hydrantor other source, andvvhich` apparatus maybejrriadj the source for ali nec-A essary hose lines "in any but 'thejmost cxtreme cases.

A second object is the provision .ofanapparatusof` this type'having means vfhereby the' pressurev at the linesmaybereadily 'and closely controlled and jin which a pluralityl4 'of diier'ent pressures may `loe simultaneously j`prvided.' the invention is the produ tion of lapparatus `QI ,thisfcliafaoter 'which is;

Another objectjof simple in its construction and operation, and may b'e readily incorporated in f lretrucls of the usual construction;

`These and other4 wherein, `for the Vpurpose of illustration, have shown a preferred embodiment of my invention and wherein:

rig.` 1 is asideflv @illustrating nre apparatus constructed in' accordance with 'my' invention; and f y I I F152 is a diagrammatic plan vieu/"showing eiateawith me tankatipnosfit sides" thereof aremanifolds ,I2 which` may, be' conveniently ar' ranged at the sidesof thelood-y ofthe vehicle, as f illustrated in Fig". l. Each 'manifold I2 has at one end thereopreterably the forward end, a plurality of valved outlets I4 and at its opposite @jaar am `by' the sofi-1 Y s'truction'shown in the accompanying drawing".

' thejhose lirie's4 already laid to the re,` and will ymicted to each" II] 4and its Adischarge 2Q Vin communication *With both of man Holdsy I2 through a conduit 'ZI having `che' c'k--valv'ed` communication with the manif oidsatfzz.A l i The highpressurepur'np I8` is provided with an inlet header 23 adapted fo'r -cpnnectionjwith the hydrant 'or other 'sourcej'of water and connected with tank I6 through" fafv'lv'ed vbranch line 24.

The discharge 25 of this pump is connected to a manifold 26, the ends o fwhich areprovided with onefor n ioreJ valve outlets 2l to which hose lines'i mayjlbe'attached. AThis manifold 26 is connected with" ma I iifolds'` i2" through valved branches 29.- Pumps'll and AINBA of course, be driven either directlyfrorn-theinotor of the truck I I, or by separatemotors, as desired.` 'f` It will be obvious that apparatus vor this type will be extremely flexible in its operation. Arriv-` ing' ata rajpuinp I1 rnay be set in -operation and hose lines attached to outlets I4 utilized to deliver the contents of tanl-I tothe re. If it appears that the fire Yis of such serious nature that the contents, of the tank will 'notjprove sfcient to extinguish the same, the inlet header 23 of pump" I8 may becorinected to one or more hydrants to supply-`additiohal Water, or such hydrants,` if available, maybe connected tothe inlets [5 of manifolds I2". A second engine arriving' on the scene may connect an outlet I4 of a manifold I2 to the manifold I2' ofthe engine first to arriveon' thescene,` as` by connecting line lhandthis procedure maybe vfollowed by all succeeding engines. v Thisv will render the Water carried or supplied by' those' 'engines available at avoid the'necessity of leading fresh lines thereto. 'I 'hs turn, will prevent entanglement and confusion ofthe-lines, andadura-stain a much moreorderly procedure. Through a series of the connections 3G, Walter may beftransported for a considerable distance, 4 from a pondA or creek, as is often necessary in rural districts' Where hydrant connections areoften not availahlafor so poorly supplied with .vvatefr that;a'jsuflicientarnount cannot be btair'ied'threfrorn.

with an assisting engine; ler1 engines; conf' riia'nifol" viusthat therel w1.l"always -be4 `available a sufl'lcient amount of Water' to' coinicaletel'y supply hose and the pressures delivered to the manifolds I2 are 100 pounds on each manifold, the valve line' I 6 of one of the manifolds may be' opened 'so that4 the pressure in the manifold is reducedto 80 pounds. Pump I8 may be operated tovdeliver a; pressure of 50 pounds to its manifold 26. It will .j be understood that at this time the check valves l of branches 22 will be closed due to the fact that the `pressure in eitherunanifold-will exceed the mean pressure delivered by pump I'Iand.

pump I'Iv is at this time discharging through its relief valve 3I into the tank I0. If the supply to-eithenmanifold I2 suddenlyfails, pump Il will immediately becomey effective to deliver water tothat .manifold so `that therewill be no failure of water at the. re, eventhough the pressure may be somewhat lower than that desired.

The pressure gauges employed, together with the .valve systems, venable a single .'operatorrto control all discharge pressure and water fromv the controlling engine, anyexcess pressure delivered being bled through line I6 into tankv It!` and, if necessary,`wasting through the overflow Illa. f

Sincethe constructionillustrated is, obviously, capable of considerable modification without ole-l parting from the spirit of Amy invention, I do not wish to be understood as limiting myself thereto except asfhereinafter claimed.
