used as shower heads One of the objects of the invention is to provide al shower head in which a variegated spray may be obtained quite unlike the spray delivery of the customary present-day type of head.
shower Another object of the invention is to provide a shower head in which the regulator for the spray and the cut-off means therefor are combined and operated by a lever conveniently accessible.
Another object of the a shower head which invention is to provide will be substantially free from scale and foreign matter and consequently will not clog and be difficult to manipulate.
Still another object vide a shower head which is of the invention is to prosimple in construction, not subject to inoperativeness and comparatively cheap With these and to manufacture.
other objects and. advantages in mind, attention is directed to the drawing, in
Figure 1 is a side er head;
Figure 2 head takenon the line Figure 3 is a section a screw 27, and said elevational view of me shewlwith a cylindrical wan as at 2s above which is 80 is a sectional view of the shower 2-2 of Figure 1; al view of the shower head taken on the line 3-3 of Figure 2, .looking in the direction of the arrows, and
Figure 4 is a top view of the spray regulating ring.
Referring more particularly to the drawing,
in which like numbers indicate like parts, there is provided the usual which is an elbow inlet pipe 1 at the end of 2 externally screw threaded 3. Within the sock- Y therein to allow adjustability of the shower head.
curely positioned the winged socket sleeve shower head may be se- The shower head comprises an enclosing member 5 of substantially bell shaped contour near the lower end of which on the insideis a substantially cylindrical surface 6, and extending downwardly therefrom a flared skirt member '7. Inside and adjacent the top of the enclosing member 5 is secured suitable means such extends downwardly a post or rod 8 by any as arms 9.
ber and is provided with a screw threaded socket at its lower end. is a spider 11 provide Sliding upon the said post,
d with a lateral extension The post -8 within the enclosing mem- 12 having a slot or groove 13 therein. Attached to the lower end of the spider is a spray regulating ring 14. It will be noted that the top edges of said ring are beveled as at 15, and there are provided annular tapered notches or grooves 16 extending through the bevels and partially down the sides of the ring. On the side of the enclosing member there is provided an apertured projection 17, which, it will be noted, extends through to the inside of the enclosing member 5. A shoulder 18 is provided near the inside opening of the aperture, and the outside opening is internally screw threaded'to receive a packing nut 19. A stem 20 rotates within the apertured projection 1'7 and is provided with a 70 flange 21 which abuts against the shoulder 18. Packing 22 and a washer 23 are provided about the stem.
Projecting from the stem is an eccentric pin 24 which flts within the slot or groove 13. A 'I5 handle 25 is attached to said stem in any suitable' manner.
A disc 26 is secured to the post 8 by means of disc is comparatively thick a beveled surface 29.
Assembling of the device is very simple. The spider is slipped onto the post 8 and so positioned that the' groove 13 is in line with the apertured projection 17. The stem 29 with the 35 eccentric pin 24 is directed into said apertured projection with the eccentric pin fitting into said groove. The disc 26 is fastened to the post 8 land the device is ready for operation.
Obviously when the handle is turned, there,J centric pin will slide the spider up and down the central post 8 and the spray regulating ring will move between the substantially cylindrical surface 6 and the disc 26. When the spray regulating ring is in its most inwardly position, the spray will be completely shut off. As it is moved outwardly, a fine spray results and in its most outwardly position, the spray will increase in volume with no increase in velocity.
The beveled edges at the top of the spray regulating ring together with the annular tapered 'notches or grooves direct the water downwardly into a most desirable type of spray.`
It will be observed that the probability of the 105 Yshower head becoming clogged with scale or forthereby cleansing the annular grooves.
The simplicity of the device is at once apparent and its advantages can be easily observed.
It will be understood that the embodiment of the invention disclosed herein is illustrative and not restrictive and that various changes in the form, construction, and arrangement of parts may be made within the spirit and scope of the following claims.
