Patented sea-1e, 1912.

To all evhom itmc'jconccm ed to be quickly loaded rom a suitable stationary tank containing liquid and thereafter carried to the lace of the fire and discharged by a suita le hand pump. To thisend I have provided a vessel to contain the liquid, as water or brine, a false head therefor normally closing the vessel while adapted to be instantly depressed into it, a )ortable tank normally resting on the false ead and havin a suitable entrance valve, and a pump an discharge hose carried by the tank. With such apparatus, in case of fire, it is only necessary to shove down into the vessel the tank until it is filled with liquid and then carry it to the place of'the fire and operate the pump to discharge the contents. The invention includes not only this broad idea but also the particular features of temporarily holding the false head to the vessel and temporarily securing the tank. to the head and of holding the pump in the tank, all of which will be clear from the descri tion hereinafter given of a preferred embodiment of the invention.

In the drawings, Figure 1 is a perspective view of my fire extinguishing apparatus, the tank being partly broken away to dis close the interior; Fig. 2 is a vertical sec: tion through the upper portion of the vessel and the'lower portion of the tank; Fig. 3 is a horizontal section through the tank looking downward; Figs. 4 and 5 are details showing the construction for temporarily holding the tank to the head, being fragmentary vertical sections, on the lines 4.4 and 5-5 respectively of Fig. 3; Fi' s. 6 and 7 are side elevations of the clamp or holding the pum in place, being respect-ively a front an rear view with the a paratus as shown in Fig; 1; Fig. 8 is a etail, being a vertical section substantially on the line 88 of Fig. 7.

As shown in the drawing, 10"repre'sents a barrel which is the vessel for containing the stored ext-inguishin liquid, which may be water or brine, or 0t er substance.

11, indicates a false head forthe barrel, the same bein shown as a iece of sheet metal flanged ownw'ardly at itsl outer edge at 12; This head is hung on the barrel by suitable metal straps 15. Three of these straps are shown riveted to the head and bent under its flange and then upwardly,

then outwardl and downwardly to provi e hooks "adapts to extend overfthe upper edge of the barrel and thus normally support the head with its load. The hooks are of comparatively light sheet metal so that an additional downward pressure on the head may strai to free'the heail the barrel.

20 indicates a tank which is adapted to receive the extinguishing liquid from the barrel, enabling 1t to be conveyed to the place of use. This tank is preferably in the form of a bucket with a cylindrical wall bottom 21 and a rigid bail 22 at the top which it may be carried. In the bottom of the bucket is a valve 30 controlling an -open-' .ing 24 through the bottom and within the bucket and secured by the bail is a The bucket, with its'pump, normal y stands on the false head 11, as shown in Fi 1.

The bucket is preferably provide on its outer side at the bottom with an outwardly projecting foot rest 25 on which the operator places his foot when working the pump. This foot rest is of use also in tempump 40.

ten the hooks sufficiently V enabling it to drop into porarily securing the bucket to the head 11.

This I accomplish by having an up-turned lip or strap 13 of the false head adapted to lie overthe foot rest. Other straps 14 extend over suitable outward projections on the bucket; Such out-ward projections are I shown in Figs. 3, 4 and 5 as made by U- shaped outward bends 26in the stifi'ening wire 27, which will lie at the base of; the vertical wall where it is curled back to join the bottom 21. The straps 13 and 14 normall hold the bucket on the head 21 but enable it I to be easily detached therefrom.

In caseof fire, a downward ressure by the operator on the bucket straightens out the hooks 15 so that the head and bucket go down into the liquid and the bucket becomes filled through-the opening 24. Then, when the bucket is raisedout of the barrel the valve closes and thebucket pulls loose from the head by straightening the retain-' -1ng straps and, with its contents, may be carried to the place of use. This operation of loading the bucket may be done very quickly. The op'ei'ator'simply takes hold of the top of the bucket Withhis-hands and pushes it down into the barrel, the. bucket automaticallyfilling. The false head thus becomes submerged in the liquid and when the bucketis lifted. out of the barrel the weight of, the water above the projecting portion of thehead insures the straps 13 and 14 bendingto allow the bucket to pull loosefrom the head,

Thevalve which controls the entrance of water into the bucket may be that shown in' Figs. 1,2 and 3 which is shown, described i at 29, to make a scatter the valve.

leather 31 rests normally on the highest and claimed in my divisional application No. 708,998, filed July 12, 1912. Such valve consistsof a disk 3O, preferably of metal, having beneath it a pad 31, which is preferably a disk of leather held in place by an under dislr or washer 32 and the central bolt 33., Su-rrounding the opening 24 in the base of the bucket ,is'the sleeve 28, which is rolled over outwardly at its upper end, as shown The point. of the curled-over edge29. Secured to the valve 30 is a sheetgjmetal strap 35 which bends downwardly and projects beneaththecurled edge, 29 to center-the valve,

as well as, to limit its upward movement. Th1s strap 35 1s shown as having four arms like a Grreekcross.v At its center this cross,-

is held by thefbolt. 33. At the edges of the 'disk 30 the arms of the cross bend downwardly at right ,angles and then bend in- Wardly beneath the edge 29. Itis to beenderstood that agreater or less number of arms than the four shown maybe employed on this strap,.if desired. Notonly does this strap maintain the disk in proper position byrallowin it to casily'move upwardly to limit its li t, but enable.v thedisk to be removed entirely whenever desired, one or two of the arms bemg simply sprung outwardly at its lower end enough to clear the edge29.

1; The pumpcarried by the bucket and designated 40 in the drawings may conveniently be lot the differential type shown, wherein there is:a vertical barrel terminating at its lower end in the housing 41 carrying asuit able intake check Valve. Operating in-the barrel-is a plunger forming a continuation of i form. The pump is provided with a suitable discharge tube 47 leading from it at the which: takes onl base of the air chamber'and to this pipe is connected a hose 48' which has a nozzle 49.

To hold the pump firmly in the bucket, as wellas'to properly position the discharge hose and also to enable the pump to be conveniently removed whenever desired I may form thebail 22 in the peculiar manner and provide it with the clamp, shown particularly in Figs. 6, 7 and 8, and which is shown, described and claimed in my divisional application No. 708,997, filed July12, 1912. 1 will now describe such structure. At the base of the air chamber 45, where it joins the pump barrel, is an outwardly pro'ectin annular shoulder 46. The bail 22 is torme with a substantially semi-cylindrical portion 50 which is adapted to snugly embrace Nithin the one side of the pump barrel. semi-cylindrical seat thus provided is a peripheral groove 51 adapted to receive substantially half of the projecting shoulder 46. On the opposite side of the pump barrel 40 is a clamp plate 60 which likewise has a semi-cylindrical body. At one edge this clamp has an ear 61 which projects between an ear 52 of thebail and the main body of the bail53 adjacent to the point where it is secured to the bucket. A pin 55 passing through the ears and into the portion 53 hinges the clamp to the bail. A suitable thumb-screw 58 passes loosely through an opening in an ear 62 on the clamping plate and screws into'a threaded opening 54 in the bail. The bail plate 50 is provided near its upper edge with a notch 57 in which rests the discharge tube 47. Accordingly, when the thumb screw '58 is tightened, thepump is clamped in place. It cannot move up or down, due to the projecting shoulder 46 in the groove 51, nor twist in the bearing, the discharge tube in the recess 57 preventing any twisting movement. Accordingly, the pump is held in the desired position. By screwing out the thumb-screw 58, however, the clamp plate may be turned back and the pump, with the hose, entirely removed,

whenever desired.

It ,will be seen from the above description that my fire extinguishing apparatus is sim ple and cheap in construction. It requires no special charging and is alwayssubstantially ready. for use. It. is only necessary to push the bucket do\vn. into. the barrel,

then carry it to te place of use and operate the pump. In such operation the operator placeshis foot on the projecting foot rest 25 and raises and lowers the plunger by means an instantflof time and use. This is accomplished by simply bending back to the original position 1e straps 1.5, 13 and 14 on the head and replacing the head with the stra s 15 overhanging the upper edge of the barrel and replacing the bucket on the head with the straps 13 and 14 overhanging the lateral rejections of the bucket. The free ends the straps 13 and 14 all project in the same direction-so that, when the bucket is being replaced, the strap 13 will stand in the opening ofthe foot rest 25 with its free end toward the arch of the foot rest and the straps 14 will stand at the rear of the projections 26 "with their free ends toward them. Accordingly, a rearward shove of the bucket in thls position brings all three straps over the correspond- 15 mg projections of the bucket, holding the bucket in place until next used.

It should be noted that, while I have described the pump and its holding device for the sake of completeness, the present invention is independent thereof. My self-loading tank may be employed with or without the pump, as desired. Also it should be noted that though the admission valve shown is admirably adapted for this purpose, I am not limited in the present application to such admission valve. For claims on the specific structure of the admission valve and on the pump holder shown reference should be had to the two divisional applications above mentioned.
