To all whom it may concern:

Be it known thatI, HART S. DE PUY, a citizen of the United States, residing at Seattle, in the county of Kingand State oWashington, have invented certain new and useful Improvements in Hydraulic Steering Apparatus, oi which the following is a specification, reference being had therein tothe accompanying drawings,

Figure 1 is a plan view of portions of a marine vessel provided with steering apparatus construct-ed in accordance with my invention; Fig. 2, a longitudinal section view one of the powercyliuders illustrated in the foregoing View; and Fig. 3, a fragmentary plan view of the valve and its controlling mechanism with the valve cylinder shown in section.

The object of this invention is the provision of a simer'ation, and which can be interchangeably employed wheel as ordinary or bypower-nieans'which is likewise controlled from the pilot house.

With these ends in view the invention consists in the novel construction, adaptation and combination of parts which will he hereinafter particularly described and claimed` In the drawings, the reference numeral 5 designates a rudder-stock to which is fixcdly connected a quadrant 6, as ordinary. 7 is a steering Wheel located within the pilot house, or at -any other suitable place upon the vessel, and is connected with saidquadrant by tiller lines 8 and 9 which are guided by pulleys 10, so that the lines will ,bc lcd downwardly from the wheel, thence transversely, thence longitudinally and finally transversely to'thcir connection with the quadrant. Included 'within the lorc-and-ait portions of said lines are rods 8 and 9l which respectively extend axially and loosely through vtubular piston-rods l1 of hydraulic er cylinders 12 which are rigidly secured to the Those piston rods have lixcdly con` n :lcd to one ond ol cach u piston l3,'scc llig. 2, which are suitably packed as by annular cup-leathers 13 to make a non-leokzthle lit with the cylinders. (lne head 14; of nach cylinder is provided with a stnlling box 14" through which thtl tubular piston-rods pass, and the opposite heads l5 are centrally upcrtured, as at l5, to allow the cable portions of thel steering lines` unobstructodly passing therethrough in thc operations oi the apparatus.

lu practice the cylinders are desirably constructed oi wrought iron pipe having screw ihrcadcd ends which I register with internal threads o the two heads. At the ends of each ol rods 8 and 9 which are adjacent oi said apertured heads is a collar lt'i adapted to be engaged hy the. respectivo pistons and move those. rods therewith, together with the connected steering pars ol the lines, y when the pistonis propelled thnreagainst hy thc'iorcc vof the power medium acting'- upon the opposite sides of the pistons. 17 represents a pump actuated desirably by steam which is admitted or throttlcd, dcsirably, by any of the Well known regulating valves, indicated by 177 which is controlled by the pressure had within the Water supply pipe 18 leading from the pump and whereby the water is continuously maintained at a suitable pressure to meet'the service required. This supplyv pipe leads to a valve cylinder .19 and from thence by pipes 2O and 20 to said power cylinders whereinto they communicate as by a port 14 in the head 14 of each. The valve-cylinder, see Fig'. 3, is provided desirably with a-liner 21 `to furnish a renewable smooth wearing surfacefor the valve and is perforated as at 21 21( and 217 positioned opposite the respective said pipe connectionswith the cylinder and serve as water portsltherefor. `v4The valve cylinder is likewise 'provided with water outlet openings 22 through which and thepipe -23 communication' is had with -a water reserillustrated embodiment of the invention is of the dou- `Pivotally connected by a pin 28 with the outer end I of the valve rod is a lever 29 having its opposite ends similarly connected by pins 30 andllwith links 30 and 31. The latter of these links make pivoted connection with an arm of the adjacent of two-levers 32* and 33 mounted upon rotatable, but otherwise nonmovable'fulcrums 32 and 33 and are'connected by reach rods 34 and 35 so that they will vibrate in unison.

Fulcrum 32/ is comprised of a vertical spindle extended upwardly through suitable journal boxes and is provided with a handle bar 36 withineasy' reach oi the steersman and whereby the latter can manipulate the valve to admit the power medium to either of the hydraulic cylinders and release it from the other and thus swing the rudder to either side predeterminately. The link 30, aforesaid, operatively connects the arm' of. the lever 29, opposite to that connected with the lever 33;

` with a crank-arm 37 secured to the rudder-stock, or

through other intermediate connections which will impart an equivalent motion to this lever. 'lhe purpose of the mechanical connection between the rudder stock und the valve is to allow the latter being operated by said lever handle when movement is to be imparted thereto by the stcersman and thus control the flow of the power medium to swing the rudder through the thrusting of the pistons of one or the other of the hydraulic cylinders acting against the opposing collar 16. When the rudder is swervedfhowever, the arm `37 cornes into play and moves the lever 29, about the pin 7 5 voir 24, which; in.turn,is connected with the cylinder 2 of the pump by a pipe 24 l The valve employed in the 31 as its axis,' to cause the'valvc being brought into such position as to intercept the further llow of the power medium into or from the r0 poctivo power cylauch power cylindor into proxiniiiy of the hoods i4, :is' indicated by hrokon linos lil in 2, Whcroupon tho rods 8 and 9 may ho movod with tho tilloi linos from the Stooi'ing \vlicol and indopondontly of the powor pistons dnd still, rol (Llodiar 36 as an indimitor to disclose the angular position olf the rudder.
