WATER-NOZZLE-FOR IM PACT WATER-WH EeLe-P SPECIFICATION formingpart of Letters Patent No. 731,570, dated June 23, 1903.
Application filed April 8, 1902. Serial No. 101.863. (No model) To all whom it mayconcern:
Be it known that I, GEORGE JI-HENRY, Jr., a citizen of the United States, residing in the city and county of San Francisco, State of California, have invented certain new and useful Improvements in Water-Nozzles for Impact Water-Wheels; and I do hereby declare the following to be a full, clear, and exact description of the same. IO This invention relates toa certain newand useful water-nozzle for use in connection with that class ofwater-wheels known as impact-wheels or those propelled by a jet of water orimpact-stream ejected against a-se- I5 ries of impelling-buckets attached to the periphery of the wheel.
Theinvention also consists in certain means whereby the outlets of the nozzle maybe con-' trolled to vary the area of the discharged 2o streams or to regulate the outlet-openings of the nozzle.
To comprehend the invention, reference should be had to the accompanying sheets of drawings, wherein- Figure 1 is a side view in elevation, disclosing the invention as applied to a tangential water-wheeh'the casing for the'wheel and nozzle being in section. Fig. 2 is a vertical sectional end view taken on line was of Fig 3o 1 of the drawings. Fig. 3 is adetail end view' of the nozzle cut-off and its adjusting mech anism. Fig.4 is a top planview of the cut off bandtfor the nozzle. Fig.5 isasectional view ofthe bandor plate. Fig. 6 is a detail 3 5 view of one of the g'uidesfor the cut-off band f and Fig. 7 isa plan view of one of the. guides,
showing a portion of the cut-oif baud or'plate therein. t
In the drawings the numeral 1 is used to 40 indicate a casing or housing of any suitable typefor the water-wheel 2, located therein; which wheel issecured to the shaft 3, working through the casing. To the periphery of this wheel issecured a series of water-buckets 4, preference beinggiven to the centrally-divided class of buckets.--
Within the housing-or casing 1 is arranged the watennoz'zle 5, which in the present case completely encircles'the water-wheel 2. This is located a distance from the water-wheel, so
place its openin s 10 in or out of as ,to give a clearance-space 6 for free rotation of the wheel within. 7 V p The water-wheel nozzle is illustrated-as be ing formed integral with coupling-section 6', which extends outside of the casing or housing and forms connection with the water-line or en pply-pipe. (Not shown.)
The water-nozzle 5 is formed with a series of outlet openings 7, arranged an equidistance apart, each opening in the present case being provided with a nozzle-tip 8, through which the water escapes. By this arrangement of a water-nozzle with a series of outletopeningsanumberofimpact-streamsorwaterjets are simultaneously discharged tangen- 6; tially against the buckets of the water-wheel.
In front of the outlets of the nozzle is located. aslide cut-0d 9, whichin the present case consists of a circular band. This cut-Oif 9 is provided with a series of openings 10, which are designed to register with the outlets of the nozzle. The cut-off works within the guide- .way formed by the flanges 11 of the plates 12 and the face of the nozzle-tips. However, any suitable form of guideway or support for the slide cut-0E may be utilized. To one portion ofthe slide cut-01f is secured the rack 13,
with whichmeshes a rack-pinion 14, attached- .toinner end portion ofpross-rod 15. This [rod extends through thecasing or housing 1 and, is supported by uprights'1611'6. Toithe endof the rod 15, projecting beyondsupport "16,,is attached a band-wheell'fifby means of which the rod is turned toactuate the rackpinion, so as to operate theslide cut-01f to re y with the outlets of the nozzle, the nozzle tips when used being considered a portion of the outlets of the nozzle 5. Bymeans of this cut-ofi mechanism the outlet-openings of the nozzle are controlled or regulated to increase or decrease the area. of the impact-streams discharged therefrom onto the water-whom buckets. I
The water-nozzle may only partially'encir- 5 cle the water-wheel; but I prefer to extend the same therearound. By 'so encircling the wheel the force of the impact-streams is evenly distributed, thereby approximately balancin g the .wheel throughout its work.
Section 6' of the water-nozzle is provided with a controlling-gate (not shown) which is raised or lowered by mechanism 18 in order to admit or cut oflf the supply of water to said nozzle from the main-line pipe.
' Having thus described the invention, What is claimed as new, and desired to be protected by Letters Patent, is-
In com bination with an impactwheel, a water-nozzle provided with a series of outletopenings, a nozzle-tip for each outlet-opening, plates secured to the nozzle on opposite sides of the nozzle-tips and projecting outwardly to a point beyond the discharge ends of said tips,
inwardly-turned flanges at the free ends of [5 the plates, and a cut-off slidable between said plates and between the flanges thereof and the discharge ends of the nozzle-tips; substantially as and for the purpose described.
In witness whereof I have hereunto set my 20 hand.
