This invention relates tov sprinkler heads for shower baths.
One important object of the invention is to provide a sprinkler head arranged to produce a ne frusto-conical spray on the exterior of a human body and a more condensed spray within such frusto-conical spray, the same being formed centrally of the shower head.
A second important object of the invention is to provide a sprinkler head of this description wherein these sprays will intersect to completely cover the person beneath the spray witha lm of cleansing water.
A third important object of the invention is to provide a head of this description wherein, by properly positioning a valve controlling the spray, any sediment collecting from the water supply to the spray will be cleared from the spray valve.
A fourth important object of the invention is to provide a central spray with a swirling motion which will spread the same out to intersect the sprinkler spray.
A fth important object of the invention is to4 provide-means whereby this spray may be regulated at any point by a single valve without shifting of the valve when released manually.
A sixth important object of the invention is to provide means whereby this spray may be positioned at various angles to the supply pipe.
With the above and other objects in view as will be hereinafter apparent, the invention consists in general of certain novel details of construction and combinations of parts hereinafter fully described, illustrated in the accompanying drawings and specifically claimed.
In the accompanying drawings like characters of reference indicate like parts in the several views, and:
Figure 1 is a side elevation of such a spray head with its connection to the supply pipe, the valve handle being shown in full lines in its intermediate position and in dotted lines in the extreme positions.
Figure 2 is a diametrical section taken through the central line of Figure 1 with the lower part of the controlling handle omitted, the valve being shown in its intermediate position.
Figure 3 is a section similar to Figure 2 but with the valve shown in its raised position.
Figure 4 is a view similar to Figure 2, but with the valve shown in its lowermost position.
Figure 5 is a bottom plan view of what will be hereinafter termed the bell of the valve.
Figure 6 is a detail end view of the valve raising and lowering mechanism.
Figure 7 is a detail view taken sectionally through the lines l-l of Figure 4 but showing only the slots producing the swirling motion of the central distributing part.
Figure 8 is a modified form of one part of the invention wherein the spray is produced in a slightly different manner from that shown in Figures 2 to 5.
Figure 9 is a bottom plan view of the modification shown in Figure 8.
Figure 10 is a section through the upper part of the valve showing a modification of the swirl producing chamber.
Figure 11V is a section on the line I I-I I yof Figure 10.
In the embodiment of the invention herein i1- lustrated there is provided a lower or body part I0 which will be preferably called a bell and this lower part has at its upper end an inwardly extending ange portion II provided with internal screw threads I2. At the lower part of this bell there is provided an inwardly extending iiange I3 which is beveled so as to provide a frustoconical part I4 and from the inner edge of this flange I3 rises a rib I5 having an inwardly extending flange I6. The inside face of this iiange, as shown in Figures 2 to 4 is provided at its upper part with a valve seat I'I of inverted frustoconical form while at its lower part it is similarly provided with a valve seat of frusto-conical form I8 having therein spaced spray notches I9, these notches being circumferentially spaced around the surface I3.
Screwed into the threaded part I2 is a nipple I9a wherein is formed a central passage 20 provided at its upper end with an enlarged portion 22 adapted to receive packing 23. The upper end of this nipple Isa is externally screw threaded to receive a packing gland 24 shaped to hold a ball member 25 having a central passage 26 communieating with the passage 20. 'I'his ball member 25 is connected by a coupling 21 with a supply pipe 28 wherethrough the device receives its water supply.
Within the bell is mounted a valve member which is built up from a central member 29 having an axial opening 30 therethrough which is aligned with the passages 26 and Y2li. 'I'his member 29 has at its upper end a flange 3I and at its lower end a flange portion 32 arranged to provide between these flange portions a groove 33 having parallel or substantially parallel upper and lower sides. At the upper end of the opening 30 there is provided a chamber 34 of considerably greater diameter than the opening 30 and into ber 34 and thus will pass out through the passage Cal 30 in a rotative manner. The lower flange 32 is provided with a beveled face 39 adapted to seat, when the valve is lowered, on the seat l1. At the lower end of the passage 30 the valve passage is enlarged to provide a screw threaded opening 4i] wherein is screwed the stem 4l of a lower valve member having an opening 42 therethrough aligned with the passage 30, flanges 43. being provided to enable this screw threading to be effected. 'Ihe periphery of this member 4| is beveled to provide a valve seat 44 which seats against the grooved part of the flange I6.
In one side of the bell there is provided a screw threaded opening 45 wherein is fitted a bearing member 46 through which extends an operating shaft 41. A packing gland or stuffing box 48 is provided to prevent leakage at this point and an operating handle 49 is attached to the outer end of the shaft 4l so that when the operating handle is swung from the full line position shown in Figure 1 to the dotted line position shown therein the valve will be actuated. This shaft 41 has at its inner end an eccentrically disposed screw threaded portion 50 on which is fitted a split nut 5| having at upper and lower sides which engage the upper and lower sides of the groove 33 so that the split nut resists turning on the eccentrically disposed part 50, the split nut being arranged to grip the part 5U firmly.
In place of having the grooves I9 made in the bell flange it may be desirable to modify the part 4l as shown in Figures 8 and 9 wherein this part is indicated at 4l' and grooves i9 are formed in the peripheral portion thereof rather than in the bell itself.
It will be observed that in either case, whether the notches Vi9 are formed in the bell, or the notches i9 are formed in the periphery of the lower part of the valve, these notches are of uniform depth and width throughout. This not only tends to ease and economy of manufacture, but also renders the flushing action for clearing out sediment much more effective.
In the modification shown in Figures 10 and 1l the part 35 is made solid without the diagonal slots 38 to produce the swirling action. in the chamber 34 and the chamber 34 is provided with tangentially arranged openings 38y which produce the same effect as the slots 38.
In either case, in the operation when the handle is swung to its central position the parts assume the position shown in Figure 2. Then, if the water supply is open, water will flow down through the central passage 30, being given a swirling motion by the beveled or diagonal passages 38, and out at the lower vend of the passage 42 so as to spray outwardly in a conical form. In this position any sediment that may have collected in the small grooves or spray notches l@ will be freely washed out thus leaving the valve free to seat. If it be desired to have a combined outward spray and central spray the valve handle 49 'is shifted to move the parts to the positions shown in Figure 3 whereupon there will be an outward spray as indicated by the dotted lines in that figure and also there will be an inward spray as similarly indicated, it being noted that these sprays will intersect. On the contrary, if one desires merely to have a central spray, as for washing the head, the handle t9 is shifted until the parts are brought into the position as in Figure 4. In this position the outward spray is cut o, as can be clearly seen, and only the inner spray is allowed to operate.
There has thus been provided a simple and eicient device of the kind described and for the purpose specified.
It is obvious that minor changes may be made in the form and construction of the invention without departing from the material spirit thereof. It is not, therefore, desired to confine the invention to the exact form herein shown and described, but it is desired to include all such as properly come within the scope claimed.
