Water.
:1A ifurther fobject lof -the vvinvention `is to profvide aJ-'simple andwinexpensive device, and ."yet ioneawhich will'lbe exceedingly 'y effective for the mpurlznose =for which itisdesigned.
V1R.felrng now lnore f Yinaifteillarly 1' to the feharrfeifeneeohtliedawings#thesprinkler comprisesafwg'nelly cylindrical body I adapted, when in use, to be `(.jlisposed with its axis vertical; saidbody lieingt'foirnedfwith an upper *Chamber *bandi aflower feh'ainber E3 V=lseparatedl by a. horizontal partition 4. t l
At its -1ower-end the --body I -s tapped for threading engagement w'th'the upper end of a vertidal stand pipe 5, through which-a i"tgater Stream i'sadapted'to'bedlverdfundebessure, *into the-lowerchamberl Y nlug "'6 is "threaded into the initially open, upper effe kof the-body 1 and," ludesrja bearing "nk 1 through "weichetubular-Stem *srextends in axially sldable, rotatable relation. The upiiowing upwardly in the stem 8 and into the reduced-diameter bore l2, causes said stem to rise from its normally lowered position of Fig. 1, to its raised operative position of Fig. 2, in which latter position the head 9 is exposed for operation. The above describes the novel manner in which the pop-up feature of the head 9 is accomplished. With the stem B, and its head 9, popped up or raised to operative position, rotation is imparted to said stem and head as follows:
Opposed bores 2I lead from opposite sides of the lower chamber 3 into vertical Vwater passages 22 formed in the body I on opposite sidesV thereof. At their upper ends the vertical water passages 22 each communicate with a corresponding duct 23 which leads into theupper chamber I, adjacent its upper end. on opposite.
sides thereof and substantially tangential to the vanes It of the rotary impeller I5.
It will be seen that with water under pressure Yflowing from chamber 3 through opposed bores 2| into the vertical water passages 22, and thence Vthrough the tangential ducts 23, such water will be projected, as pressure streams, against the vanes I6, causing relatively high speed rotation of said impeller I5. This high speed rotation of the impeller I5 is not fully imparted to the stem 8, but rather a relatively slow rotation of said stem results by reason of the undulate cam I9 running in frictional engagement with the bosses I'I. There is of course a high slippage between the undulate cam I9 and the bosses Il, which accounts for the desirable relatively slower rotation of the stem 8, as compared to said impeller I5.
By reason of the fact that the enlarged annular bottom flange i8 forms a closure between the lower ends of the vanes I6, a downward pressure is exerted on said ange when the device is in operation, which downward pressure maintains the undulate cam IS in proper working engagement with theY opposed bosses Il'.
After the water leaves the tangential ducts 23, and works the impeller I5, said water flows, within the upperA chamber 2, Ydownwardly to entry into the stem 8, whence it flows upwardly with the jetted stream from nozzle 20 for discharge' through the sprinkler openings of the head 9.
After use of the sprinkler and shutting on of the water pressure, the stem and impeller unit fall yback to their starting positionsA rby gravity,
at which time the head 9 is again'in its protected position Vin the bearing neck l.
It will'be recognized that by reason of the described structural arrangement,popping up and rotation of the head @i is automatically accomplished, upon introduction of water under pressure, into the sprinkler; and further, the design of suchsprinkler is such that foreign substance such as sand, which may enter the sprinkler during use thereof, cannot cause any blocking or malfunctioning of the device.
j y From the foregoing description it wil be readily seen that there has been produced such a device as substantially fullls the objects of the invention as set forth herein.
While this specification sets forth in detail the present and preferred construction of the device,
still in practice such deviations therefrom m'ay be resorted to as do not form a departure from the spirit of the invention, as dened by the appended claims.
Having thus described the invention, the following is claimed as new and useful, and upon which Letters Patent are desired:
'1. Inra `sprinkler head which includes a. hollow body having a water inlet and a nozzle member mounted for rotation relative to the body and which nozzle member has a stem projecting into said body; a means for effecting rotation of such nozzle member, such means comprising a water actuated impeller turnably mounted on the stem within the body, and a slip-drive connection between the impeller' and stem operable to rotate the stern at a relatively slower speed than that of the impeller, the stem of the nozzle member being movable vertically through the upper wall of the body, the side wall of the body being provided with transversely disposed bores adjacent its upper end, the impeller normally lying below the horizontal plane of the bores when the stem Vis in its lower position, and said impeller being lifted into said plane upon vertical movement of the stem, and conduit means for supplying water `which nozzle member includes a tubular stem projecting into such body; a means forelecting rotation of such nozzle member, such means comprising a water actuated impeller turnable on the stem within the body, conduit means to admit Water under pressure into the body andV against said impeller, a boss mounted on and projecting radially out from the bottom ofthe stem and a downwardly facing. undulate cam on the impeller bearing against the boss. Y
4. In a sprinkler head which includes a hollow body and a nozzle member mounted for rotation relative to the body and which nozzle member includes a stem projecting into the body and being movable vertically relative thereto; armeans for effecting rotation of the nozzle member, such means including a second hollow body about the first body, means to admit water under pressure into the second body, a water nozzle opening through the bottomof the rst body into the second body, the stem restingadjacent said nozzle when in its lower position and being liftable vertically in response to water under pressure moving throughsaid nozzle, opposed boresinthe side wall of the first body adjacent the top wall thereof and opening communication betweenthe first and second bodies, an impeller mounted about the lower end ofthe stemY and connected in driving connection therewith, said impeller being disposed below the planeof. thevopposed bores when the stem is in its lower position, such impeller being carried vertically into the Aplane of such bores when the stem moves vertically.
