Original application November 23, 1934, Serial 7 Divided and 'this application March 4, 1935, Serial No. 9,326

4 Claims. (01. 251-40) This invention relates to sprinkler heads for shower baths and has special reference to operat ing means for such heads, the present invention being a division of my copending application for ,Sprinkler head for shower baths, Serial No.

= provide the movable member of such head with a peripheralgroove to receive the pin or eccentric. One difficulty with the ordinary types of such constructions resides in thefact that the pressure of water on the movable parttends to fully open the head.

An important object of the invention is to provide actuating means of the character above noted which will prevent, by friction between certain parts, any movement of the movable part of the head except such movement as may be effected through manipulation of the handle.

A further objection to the usual construction of this character arises from the fact that wear due to continuous use loosens the pin or eccentric in its groove and renders the movable part more liable to shift position as the wear increases.

A second important object of the invention is to provide actuating means of novel construction in which such wear will not affect the holding of the movable part in desired position.

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 drawing and specifically claimed:

In the accompanying drawing like characters of reference indicate like parts in the several views, and:

Figure 1 is a vertical diametrical section through a sprinkler head provided with actuating means in accordance with this invention, the movable part of the head being shown in raised position.

Figure 2 is a similar section showing a modifled form of the invention but with such movable part in its lowest position.

Fig. 3 is a detail end view of the means for raising and lowering the sprinkler head.

In the embodiment of the device as shown there is provided a lower part or body l having a flange ll extending inwardly from its upper part and provided with an internal screw thread for connection with the hollow bonnet l2 connected by a ball and socket joint I3 with the supply pipe M. The lower end of the body carries an inwardly projecting flange having'a bevelled valve seat l5 at its upper edge and .reversely bevelled as at H5 at its lower edge,;this' bevelled portion 16 being provided with a'series of sprinkler grooves or notches l1. 5

The movable member or valve of the head is indicated in general at i8 and at the lowerend of the member 18 there is provided a peripheral groove l 9 above which is a bevelled valve face 20 adapted to seat on the valvefseat l5. Below the groove I9 the movable member is provided with a valve face 2| adapted to engage the bevelled portion l'I. When in its lowest position the valve face 20 'coacts with'the valve seat I5'to close off the sprinkler; when in its fully raised position the valve is open and the face 2| and bevel IT coact to provide a series of fine spray streams; and in intermediate position neither valve face is seated and flushing takes place. Around the central part of the member I8 is a peripheral groove 22 and a guide spider 23 is carried by the upper end of said member l8 to fit in the bonnet l2 and thus guide the movable member.

In one side of the body l0 there is provided a screw threaded opening 24 wherein is screwed a bearing member 25 through which extends an operating shaft 26. A packing gland 21 is screwed into the outer end of the member 25 to compress packing 28 against the shaft 21 and thus make a water-tight fit at this point. An operating handle 29 is fixed on the outer end of the shaft 26. At the inner end of the shaft 26 is an eccentric collar 30 resting against the inner face of the member 25 so as to prevent movement of the shaft outwardly. Extending from this collar and coaxial therewith is an externally threaded pin or eccentric 3| constituting an offset inner end for the shaft and whereon is fitted a nut 32 split on one side as at 33 and of such material as to be sumciently resilient to grip the threaded pin by spring action and thus to maintain friction be-' tween the pin and nut.

Also the nut has flat upper and lower sides which engage the sides of the groove 22 so that the nut cannot rotate in the groove. By reason of this construction the nut constitutes means frictionally engaging the pin or eccentric so that it requires considerable force, such as may be applied by the operating handle 29, to effect, movement of the movable member in the body. Moreover, if the pin or the pin engaging surface of the nut wears the spring clamping effect of the nut will compensate for such wear. Also, if wear occurs between the nut and the groove 22 no injurious effect will be proc a m d as w s:

duced since no ordinary amount of wear will permit rotation of the nut in said groove but the nut will always be held against such rotation. It is to be noted that the provision of the screw connection between the nut and pin affords much greater friction surface than there would be if a plain cylindrical fit existed between these parts.

In the modification shown in Figure 2 the threaded members 3| and 32 are replaced by plain bearing members 3| and 32' the construction being otherwise like the form shown in Fig; ure 1. 1 r

There has thus been provideda simple and efficient device of the kind described and for the purpose specified. I

It is obvious that minor changes may be made in the form and'construction of the. invention without materially departing from the spirit thereof. It is not, therefore, desired to confine the invention to-the exact form herein shown and described, but-ibis desired to include all such as properly come within the scope claimed.

'Having thus described the invention, what is -1'.'In a sprinkler head for baths, a hollow g a a valve controlling the flow of water through said body and having a peripheral groove extending therearound, an operating shaft extending through the side of said body andhaving an eccentrically oifsetinner end entering said groove,

anda resilient split friction member fitting in said groove and frictionally' clamping said offset end, said friction member and groove. being cooperatinglyarranged to prevent rotation of the friction member,- on its, axis in'saidgroove.

2. In a sprinkler head for baths, a hollow body, a valve controlling the flow of water through said body and having a peripheral groove extending therearound, an operating shaft extending through the side of said body and having an ec- 1 centrically offset inner end entering said groove,

and a resilient split friction member fitting in said groove and frictionally clamping said oiTset end, said friction member having flat faces engaging the upper and lower'sides of said groove.

3. In a sprinkler head for baths, a hollow body, a valve controlling the flow of water through said body and having a peripheral groove extending therearound, an operating shaftextending through the side of said body and having an eccentrically offset inner end entering said groove, and a resilient split friction member fitting in body and having a peripheral groove extending therearound, an operating shaft extending through the side of said bodyand having an eccentrically offset lnner end entering said groove, and a resilient split friction'member fitting in said groove and frictionally clamping said offset end, said friction member havingflat faces en-" gaging the upper and lower sides of said groove, said friction member being internally threaded and the offset end being threaded for screw en-v gagement in the friction member.
