Emergency shower heads have been designed for the protection of personnel working in chemical laboratories, machine shops and other places of employment, where injury byv either fire or chemicals is a possib lity and where it is necessary to have available an emergency shower that is capable of immediately delivering the largest possible volumeof water.. v I

Heretofore shower heads have been. so designedas to deliver water from an inverted bell head. These heads have either had a face plate with perforations therein,

3,008,652 Patented Nov. 14, 1961 2 the center'of the stud.25.. This face member 24 is adjust'ab-le to allow an opening27. between the body 20 and the face member 24. The face member shown indetail in FIGS. 1, 2 and 3 :has-a series of angular vanes 28, 28 thereon. Thesevanes originate adjacent to the stud12'5 and'curve'outwardlytowards the periphery of the face member 24, and fare'machined down on. the outer edges 29 (shown in FIG.- 2). These vanes cause the water flowing .therebetween to take a rotational motionL The'vanes28, 28 having the upper part29 are in contact with the inside of the inverted bell shaped body 20 and having the openings '28atherebetween shown in FIG. 4. Theface member 24 has circular grooves 30 which tend to becomeclogged, due to lack of use, or H It is an object of the present invention to providefan I emergency shower head of the face member type having certain openings through this face member: to allow control of the water within the cur-tainffor'medby'the openings between the face member and the showerliead body Y :'-;..Z

The many'fe'atures of novelty which characterize this invention will be apparent from the description and claims annexed .to and formingpart of this specification.

Reference should be had to the accompanying drawings and descriptive matter for a better understanding of .the

invention, in which is described and illustrated "theipreferred embodiment of the invention. i

FIG. 11 is a sectional view on line 11-11 of FIG. 9.

FIG. 12 is a fourth modification, taken in section on line 1212 of FIG. 13.

FIG. 13 is a plan view of the modification shown in FIG. 12.

The emergency shower head has an inverted bell shaped body 20 (shown in FIGS. 4 and 5) having a water inlet opening 21 in the upper end thereof and having a water outlet opening 22 in the lower or larger end thereof. Mounted across the water inlet is a spider 23 on which is mounted the face member 24 by means of the threaded stud 25 at the center thereof, this being locked in position by means of the screw 26 which is threaded into and 31 cut therein. The'se grooves are cut throughthe facemember but not thro'ugh' thevanes 28. The vanes will therefore hold the face member in assembly after the grooves have been cut. These -grooves 30 and 31 (shown in FIG. 1) have sides 32 adjacent to the axis of the face member out perpendicular,v and opposite sides 33 cut on an angle to. give a w'ider 'stream as shown in FIG. 3. V

' A second modification of this device is shown in FIGS. 6, 7 and 8, wherein thevanes have been omitted and the lugs 34, 34 are placed thereon so as to hold the face member in assemblywhen the grooves 35, 35 are cut therein. These grooves are made in the same manner as the grooves 30, 31 as ShOWn in FIGS. 1, 2 and'3, and have the sides 36, 36' remote from the axis cut. at an angle to'thei face member and the sides 37, 37 adjacent to the axis perpendicular to the face member.

A third modification, shown in FIGS. 9, 10 and ll has short straight vanes '38, 38 on the upper surface of the 'face member, and tend to force the water outwardly in a circular motion. Grooves39, 39 are-cut radially in the face member to allow water to escape therethrough.

Another modification "of this invention is shown in FIGS. 12 and 13, wherein the face member .40 is the same as that shown in FIGS. 1, 2 and 3 except that the circular grooves 30 and 31 are omitted, but the body portion 41' has the deflectors. 42, 42 on the interior surface thereof. These deflectors are not arranged radiallyfwith' respect to the body portion but are arrangedat an angle so as to intercept the water discharged by the face member and deflect it inwardly.

In operation, the emergency shower, shown in FIG. 4, is assembled so that the opening 27 is a discharge port for the water. The source of Water (not shown) is attached bymeans of a' nipple or other connection (not shown) to the water inlet opening 21 and flows into the upper part of the body portion 20 behind the face membin-"24. It is discharged from this part of the shower head through the. opening 27 along the interior surface of the lower part of the body portion. This water is givena. swirling motion by the vanes 28 whichtend to force the water against the inside surface of the lower discharge water within that portion flowing through: the

opening 27. This avoids the hollow'curtain of water heretofore commonly found in emergency showers, as the water flowing through 30 and 31 discharges within the curtain flowing through the opening 27. In order to impart the swirling motion of the water discharged through 27, modifications of the vanes 28 are shown in FIGS. 9, 10 and 11, wherein the vanes 38 cause the same turbulent motion and the grooves 39 admit the water to the central part of the shower. The face member shown in FIGS. 6, 7 and 8 does not impart any turbulent mo tion to the water discharged but does have the grooves 35, 35 therein which admit water to the central portion of the shower.

The modification shown in FIGS. 12 and 13 has vanes 40a on the face member and also has deflectors 42, 42

in the lower part of the body portion. The water discharged through the opening between the face member and the body portion is discharged with a turbulent motion,,where most of it will follow the flare in the lower part of the body 41, but some will be deflected inwardly as it strikes the deflectors 42, 42, which reverses this turbulence, and thereby forces the water inwardly towards the center of the shower.

The above description has defined a novel face plate and several modifications thereof. It has also defined a bell shaped body and a modification of this body comprising an addition thereto of water deflectors. Any of the face plates mentioned above may be used in any of the bell shaped bodies as these are all interchangeable.

While in accordance with the provisions of the statutes, there has been illustrated and described the best form of embodiment of this invention now known, it is apparent to those skilled in the art that changes may be made in the form of the apparatus disclosed, without departing from the spirit of the invention, which is only limited by the claims appended hereto.
