This invention relates to lire extinguishers ofthe hind that comprise a manually-operf able pump for discharging the liquid contents of the container through a hose.

way that the han piece on the upper end or' said plunger can be used as a handle `for Vcarrying the extinguisher. y

Another object is to provide a `fire extinguisher of the type referred to in which the cylinder or barrel of the pump `is provided at its upper end With a part arranged on the outside of the liquid container of the extinguisher and equipped with a hose connection, thereby simplifying the construction and reducing the cost of manufacturing the extinguisher, as well as makinlg it possible to have an inclined outlet, as distinguished `from a right-angular outlet from the pump barrel to the discharge hose.`

Figure l of the draWiIfgsis a vertical sec tional view oi a hre extinguisher constructed in accordance With my invention.

Figure Q is' a perspective view of the removable member in theloiver end of "the pump barrel that carries the strainer4 or screen and the cage'forfthe inletvalve of the pump; and

Figure 3 is a perspective view of the hand piece on the upper end of the plunger of the pump.

Referring to the drawings which illustrate the preferred form of my invention, A designates the liquid container of my iinproved ire extinguisher, which preferably consists of a cylindrical-shaped member provided With a bottom 1 and a dome-shaped top 2, B designates a verticallydisposed pump cylinder or barrel arranged inside of the liquid container A and provided at its upper end with a part C arranged on the upper side of the top 2 of the container A and provided with a. hose connection 3, D designates the hollow plunger of the pump Which projects through a stuffing box E carried by the part C on the pump barrel, said plunger being of conventional form and provided at its lower end with a piston having a reduced portion of less diameter than the pump barrel so as to permit the liquid in the plunger to escape from same into the barrel through ports 20 in the reduced portion of the piston, F designates a hand piece rigidly connected to thequpper lend of said plunger and G designa-tesa hose at tached to thehose connection 3 at the upper L end of the pump barrel. o

` One object of` my. invention is to provide a lire extin uisher ofthe type reiterredtoV that is equipped with a. novel means for` locking the plunger or' the pump in such aV In order that the hand piece on the hand vided for locking said hand pieceto the stuilingbox E. Injthe form of my invention herein illustrated 4the Kmeans referred to consists of a4 `pin 4 that is adapted tobe inserted through aligned holes in lugs 5 on the stuiiing box .E in such a Way that it is positioned in a slot or groove 6v in the hand piece F, as shown in Figure l, thereby prei venting the pump plunlger and the hand piece F thereon from` turning or reciprocating relatively tothe pump barrel or to the liquid Icontainer A` of the extinguisher.

plunfrer of the ump may be used as a,` le to carry t e container means is pro-` `lli/Then it is desired to use the pump the pin l is withdrawn from engagement with the lugs 5 and the slotted portion of the hand :pico-*Ig F, thereby permitting the pump plunlger .cylinder B of the pump. 4The locking deto be reciproca-ted in the barrel or vice d is upreferably connected to a chain` or from becoming lost when it is not in use,

the chain 7 beingv herein illustrated as connectod to a handle 8 on. the container A and secured toa filling plug 9 inthe top 2 ofthe container through which the liquid is introduced into the container A.

By providing the member C at the upper end of the pump barrel with a hose connection 3 that is arranged on the outside of the liquid container A, I overcome the necessity of forming a hole in the side Wall of the liquid container, and another advantage that results from such a construction is that the duct l() that connects the pump barrel with the hose G can be arranged in an upwardly-inclined position instead of at right angles to the pump other flexible element 7, so as to prevent it i by a disk-shaped, perforated element that is substantially Hat and set Hush in the lower end of the member H and said mem ber is provided with an externally screwthreaded portion 14: that is screwed into the lower end of the pump barrel B, as shown more clearly in Figure 1. The cage for the vball check valve 13 is formed by a pair of integral lugs l5 that project upwardly into i cage for thecheck valve 13.

the pump barrel and each of which is provided with a slot or bifurcation 16, as shown in'Figure 2, thus forming four upwardly-projecting fingers that form a Usually the memberV H is formed from a casting, and after the check valve 13 has been positioned between the upwardly-projecting lugs 15 on said member, the ngers formed by the vertical slots in said lugs are bent inwardly slightly over the check valve, as shown in Figure 2, so as to limit the upward movement of said check valve relatively to its lseat. Such a construction is inexpensive to manufacture, and as the screen or strainer 12 is Vpositionedl in close proximity to the bottom lof the container A, practically allv of the liquid in said container can be` pumped outL of same by operating the Aplunger of the pump.`

The liquid container A is provided at itsvlower end with a combined Jfoot piece and handle I that consists of a loop or bale lequipped with an angularly-disposed part --or crank portion 17 which is surrounded by a bracket 18 on the container. When the device uI is not in use it can be folded up against the side of the container, as shown in broken lines in Figure 1, and when the pumpV of the extinguisher is being used, said device I can be 'swung downwardly into the position' shown in full lines in Figure 1, so as to serve as a foot piece on which the user can exert pressure with his foot so as to hold the liquid container A stationary when theplunger of the pump is being reciprocated. Gwing to the tact that the device I is provided with an angularly-disposed part lor crank portion 17 which turns in a bea-ring or bracket 18 on theside of the container A, it is impossible for said device I to swing into a position under the bottom of the container or underl the lower edge of the container, and thus prevent the container from bearing evenly or resting squarely on the'loor or other supporting structure on which it rests.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

In a tire extinguisher, a liquid container, a pump cylinder in said container provided at its upper end with a member arranged on the outside of the top of said container piece, and a removable locking pin that` is adapted to be inserted through said lugs and positioned in the slot in said hand piece, for the purpose described.v
