OUTLET GUARD.
Application filed July 24, 1925.
This invention relates to outlet guards for liquid receptacles particularly adapted to guard the outlets ethic extingu shers oi the types containing a liquid held within the receptacle and another liquid adapted to react with the first mentioned liquid to pro duce a gas, the last mentioned liquid held within a container carried in the receptacle or otherwise normally separated from the first mentioned liquid, the fire extinguishers being adapted to be put into operation by 111* verting them or otherwise causing the two liquids to come in contact with each other, whereby a g: s is generated which creates a pressure acting to discharge the l1qu1d contents of the receptacle through the outlet opening, the latter usually arranged at the top of the receptable and above the normal level ot the liquid in the receptacle. Such lire ezi'tinguisbers may be of the pressure type or the foam type.
l i ith fire extinguishers of the pressure or foam type it has been found diiiicult to prevent the escapc of liquid from the receptacle when subjected to undue shaking or ag tation, such, for example, that resulting from the movements of a railway car or other vehicle upon which the extinguisher is carried.
An object of the invention is to arovide an outlet guard which is adapted to be connected to the inner wall of the tire extinguisher adiacent the outlet thereof and is so constructed as to prevent escape of the liquid due to slopping action thereof.
Another object of the invention is to provide a guard or" the character mentioned which, while it functions eilectively to prevent the'escape or liquid by slopping action,
is readily accessible for cleaning without.
uncovering its strainer or moving any part oi it from normal position, a rd which, while it will effectively prevent undue escape 0t liquid when the extinguisher is not in use, will nevertheless permit an unr stricted flow of the liquid through the outlet when the e1:- tinguisher put into operation.
Other objects and advantages of the in vention will become apparent from the following description when taken in connection with the accompanying drawings in which- Figure l is an elevation, partly in section, of the upper portion of a fire extinguisher- Serial No. 45,782.
having my improved out-let guard applied thereto.
Figure 2 is a vertical sectional view through the outlet guard and the fire extiu guisher outlet.
Figure 3 is aface View of the outlet guard.
Figure ii: is a face view of a baffle plate.
Figure is an edge elevation of the ballle plate as viewed from above in Figure 4-.
The drawings show a fire extinguisher ot the type adapted to be normally held or car ried in an upright position and to be inverted to effect a mixing of the liquids when it is desired to place the extinguisher in operation. The receptacle 5 of the extinguisher herein shown is provided with the usual removable cover 6 and with the outlet 7, the latter carrying a discharge hose 8 and coinmunicating with the receptacle 5 at the up per end thereof above the normal liquid level.
The outlet 7 is provided with a flange, as shown in Figures 1 and 2, and is adapted to be brazed or otherwise suitably connected to the wall of the extinguisher. Over the inner end of the outlet 7 is positioned the outlet guard embodying my invention and shown as comprising a balile plate 9, which is socured, as by soldering, to the inner wall of the extin uisher, and is so formed as to pro vide an overhanging deflecting wall 10 which carries an annular seat 11 and is con nected to a concave-convex centrally located shield portion 12 by means of radial arms 13, between which are formed arcuateshaped openings 14', This centrally located shield portion 12 is located at such a dis tunes from the opening of the outlet, and the openings between the radial arms 13 are of such width, as to provide an ample runway for liquid to the outlet opening when the receptacle is inverted. It will be noted that the shield portion 12 is somewhat larger than the opening of the outlet 7 and that this is arranged concentrically with the entrance to the outlet 7. By reason of the fact that the shield portion is positioned directly in trout of the opening of the outlet and overlaps it in all directions, it affords an effec tive obstruction to any liquid which may be unduly directed toward the outlet from the front or convex side of the baffle plate. The deflecting wall 10 is, as shown most clearly in Figure 2, so extended that a plane coincident with the front edge thereof is further from the outlet opening than the plane of the outer edge of the shield portion 12, and thus the deflecting wall overlaps the entrance to the outlet in planes at right angles to the axis of the opening. It is obvious that the deflecting wall 10 will elfectively obstruct and throw back away from the outlet such liquid as may be unduly directed toward the entrance to the outlet along the wall oi: the receptacle within the range of contact with the deflecting wall, and that any splashing liquid which approached clear of the deflecting wall and which escaped the backfiow caused by the deflecting eifect of this overhanging wall, would be obstructed by the shield portion 12.
Inorder to further obstruct undue passage of liquid from the extinguisher into the outlet 7, a perforated concavo-convex guard plate 15 is provided. This guard plate is adapted to be suitably connected, as by means of solder, to the batl'le plate 9, this guard plate having a flange 16 adapted to rest upon the annular seat 11 of the baffie plate 9. The perforations in this guard plate 15 provide ample passageways for the liquid during normal operation of the extinguisher, but the portions of the guard plate between the perforations obstruct the passage of liquid by splashing and the guard plate, as a whole,
acts as a strainer. By reason of the coact-ion of this guard plate 15 with the other fea tures of my invention it does not have to be covered or externally shielded and is therefore readily accessible for cleaning.
In order that the outlet guard, in its entirety, may be fitted snugly to the wall of the extinguisher, both the baffle 9, and the guard plate 15 are cut away at the top, as shown most clearly in Figures 3 and at, to accommodate them to the neck 17 or other obstruction at the upper end of the extinguisher.
What I claim is 1. An outlet guard for liquid receptacles, comprising a baffle plate attached to the receptacle and positioned in front of the out let, and a perforated guard plate positioned in front of and attached to the battle plate and spaced therefrom.
2. An outlet guard for liquid receptacles, comprising a baffle plate permanently attached to the receptacle and positioned in front of the outlet, and a perforated guard plate positioned in front of and permanently attached to the baffle plate and spaced therefrom.
3. An outlet guard for liquid receptacles, comprising a bafiie plate attached to the receptacle and positioned in front of the outlet, a deflecting wall on the baffle plate extending inward from the wall of the receptacle, and perforated guard plate positioned in front of and attached to the hafiie plate and spaced therefrom.
4. An outlet guard for liquid receptacles, comprising a baffle plate attached to the interior of the receptacle and positioned in front of and spaced away from the outlet, a deflecting wall on said ballle plate extending inward from the wall of the receptacle, and a perforated guard plate positioned in front of and attached to the baffle plate and spaced therefrom.
5. An outlet guard for liquid receptacles, comprising :1 baths plate attached to the interior of the receptacle and positioned in front of and spaced away from the outlet, a deflecting wall on the baffle plate extending inward from the wall of the receptacle, and a perforated guard plate positioned in front of and attachet to the baliie plate and positioned within the deflecting wall.
6. An outlet guard for liquid receptacles, comprising means for preventing the contents of the receptacle from entering the outlet when subjected to a slopping action, said means comprising a baiile plate attached to the inner wall of the receptacle and positioned in front of the outlet, at deflecting wall on the bathe plate extending inward from the wall of the receptacle, and a perforated guard plate attached to and posi- 'ioned in front of the baffle plate and spaced therefrom, the deflecting wall serving to divert liquid from the perforated guard plate when the liquid is subjected to a slopping action.
7. An outlet guard for liquid receptacles comprising a baiile plate having a concaveconvex shield portion positioned in front of the. outlet and a concavo-convex perforated guard plate positioned in front of the shield portion and spaced therefrom and a deflecting wall adjacent the guard plate and outlet, the bailie plate and the guard plate being anchored with respect to each other and with respect to the outlet.
8. An outlet guard for liquid receptacles, comprising a hailie plate having a shield portion positioned in front of the outlet and provided with a deflecting wall, and a perforated guard plate positioned in front of the shield portion and spaced therefrom, the guard plate being seated upon the baffle plate intermediate the shield portion and the deflecting wall.
In testimony whereof, I have afiixed my signature to this specification.
