p HYDRAULIC SUPPORT Fon DEFLECTING NozzLEs.
To all whom w may' concern;-
.Be itlmown thatl, GEORGE J HENRY, Jr., a'citizen of the United States, residing in the cit and county of San Francisco, State of (la ifornia, have invented certain new and useful- Improvements in Hydraulic Su ports for Deflecting Nozzles; and I do;l1ereii act descriptionof the same. ,y The-present invention is more particularly designed for use'in connection with adeflect-- `ingn'ozzle forv controllin the discharge of alpropelling stream onto t e buckets or vanes fof Van ordinary tangential water-Wheel, the l'object yof the invention being to'support the outer end of thedeflecting nozzle and hold should be f the same in any of its adjusted positions by means of ressure from the main or line pipe supply t ereby dispensing with the heavy adjustable weight-.ordinarily em loyed for counterbalancingthe Weight of t e said delectab'le nozzle and making the nozzle more 'sensitive andresponsive to the action of the governor mechanism which actuates the same than is possible by the use of .such countertherein, said cylinder and piston being sectioned vertically, connection between the pis- -ton and the nozzle, and connection of the piston-stem .and an actuating rock-shaft, also communication between the cylinder andthe main or line pipe. Fig. 2 lis a detail view,
' partly iii section, of .the valve 14 hereinafter referred to.
Inl the drawings the numeral 1 is used to designate an ordinary tangential water-wheel with the bucket 2 applied to the periphery thereof, and 3 a movable nozzle or deflectable device for directing an impelling stream onto v.or ofl" ofthe bucket 2 of the wheel .This i, nozzle 3 is pivoted to the end of the imam or line pipe 4, which sup lies water to the nozzle `3.' These parts are o the usual construction and the Working thereof well understood te 'those skilled in the art.
To the outer end portion of the deilectable nozzle 3. is attached the upper end of the` i Specication of Letters Patent. Application flied october 15. 1994.
xde- .clare the following tobe a full, cleaij'nd eX- Patented Jan.'23, 1906.
serial No. 228,550.
jointed piston-stem 5, said stem at its lower 'end carrying the piston 6. It will be understood that the connection between the istonstem 5, the deflectable device 8, and t e pis- 'ton 6 is a' jointed one in order that the said piston-stein may be `free to swing in accordance With the arc described bythe movement ofv the-deflectable device 3. I This piston Works within the-,stationary pressure-cylinl H der 7, it being supported therein b the body of li uid 8. `In tpe present case' th liqui consists o Water delivered into the said-cylinder 7 under'pressure from themain or line-pipe 4, communication between the said line-pipe and the cylinder 7 being estab-- lished by means ofthe branch supply-pipe 9, the flow of water being regulated by the controlling-valve 10.
The nozzle 3 is operated bythe movement of a rock-shaft 11, which rock-shaft is connected to the governor mechanismy (not shown) by any ysuitable form of connection. From the rock-shaft 11l extends a crank-erin 12, which crank-arm forms connection between the said rock-shaft and' the lpiston stein or rod 5, so that as the rock-shaft is moved to raise or lower the crank-arm l2 the piston stem or rod is carried therewith.'
To relieve theA cylinder 7 of its liquid during the downward movement of the piston 6 upon the nozzle being deflected, rather than force the liquid back into .the main or line pipe 4, there is provided an escape or outlet pipe 13, which leads from the lower end of the said cylinder. In this escape or outlet pipe there is arranged any suitable forni of an escape or safety valve 14, which valve is unseated or raised from its seat by the pressure of the retained liquid exerted thereon upon the downward movement `of the said piston, which pressure exceeds that of the maintained pressure from the main or pipe line 4. The resisting pressure ofthe valve 14 e body of.
may be varied by simply increasing' or decreasing the tension of the spring 14', which may be accomplished by adJusting the cap As the nozzle 3 is raised or elevated it is ifeld in such adjusted position by the waterpressure admitted into the cylinder 7 back of the piston from the main or line pipe 4.
The described hydraulic support for the deflectable nozzle is extremely sensitive to any variation as to the nozzles position and IOO value where` quick adjustment orchange of the nozzle is required to direct a greateror less area oi the impact-stream onto the buckets of the wheel tomeet the requirements of sudden load changes placed onto the wheel.
The diameter of the piston operating in cylinder 7 should be made such that the pres.-
ing valve 14 as to permit of a slight discharge, A
the pressure exerted against the piston 1n cylinder 7 may be reduced, thus providing an adjusting means to counterbalance the delectable nozzle.
Having thus described the invention, what is claimed as new, and desired to be protected by Letters Patent, is
1. The combination with a deilectable nozzle for water-wheels, of hydraulic means for supporting the said nozzle when at rest, and mechanism for controlling the position of the nozzle. l
2. The combination with a deilectablenozzle for water-wheels, of a cylinder, a piston working therein, a liquid-support within the cylinder for the piston, oi. connection between the piston and the nozzle, a rock-shaft, and means for imparting the movement ol the rock-shaft to the nozzzle in order to adjust the position thereof:
3. AThe combination .with a defiectable nozzle, of a main or line pipe to which the same is pivoted, a pressure-cylinder, of connection between the said cylinder and the main or line pipe, a piston working within the cylinder, connection between the piston and the nozzle, and means for imparting movement to the saidnozzle so as to place the stream dischar ed therefrom in whole or in part onto the buc ets of a water-wheel.
4. The combination with a deilectable nozzle, oi a main or line pipe to which the same for such reason renders the same of great is pivoted,
l a pressure-cylinder, of means for admitting iluid under pressure thereto, a piston Working within the said cylinder, connection between the piston and the nozzle, and means for moving the nozzle so as to direct the stream discharged therefrom in whole or in part onto the buckets of a water-wheel.
5. The combination with a deilectable nozzle, of a main or line pipe to which the same is pivoted, a pressure-cylinder, of connection between said cylinder and the main or line pipe for admitting fluid thereto under ressure, a piston woiring within the cylin er, a valved outlet for the said cylinder, connection between the piston and the nozzle, and means for adjusting the position of the nozzle vso as to direct the stream discharged there- Jirom in whole or in part onto the buckets of a water-wheel.
6. The combination with a water-Wheel, of a main-line supply-pipe, a delectable device located at the outer end of the supply-pipe for changing the position of the jet issuing therefrom, oi hydraulic means for balancing said device, and mechanism for controlling the pos1tion ofthe deilectable device.
7. The combination with a water-wheel, of a main-line supply-pipe, a deflectable device located at the end of' the supplypipe for changing the position of the jet issuing therefrom, and fluid-actuated means for balancing said deiilectable device.
8. The combination with'a water-wheel, of
a main-line supply-pipe,- a deflectable nozzle pivoted to the outer end of the suppl -pipe, said nozzle being rigid throughout its llangth, mechanism for varying the position of said nozzle to direct the jet issuing therefrom ontof .or off the buckets of the water-wheel, and. fluid-actuated means for balancing the said nozzle.
