ADOLPH HELLINGER, OF ST. LOUIS,MISSOURI.

REGULATING PROPELL ERS OF VESSELS.

SPECIFICATION forming part of Letters Patent No. 474,169, dated May 3, 1892.

Application filed January 1 6, l 8 91.

To all whom it may concern:

Be it known that I, ADOLPI-I HELLINGER, a citizen of the United States, residing in the city of St. Louis and State of Missouri, have invented certain new and useful Improvements in Marine Governors, of which the following is a full, clear, and exact description.

My invention relates to means and devices for regulating the speed of revolution of the screw-shaft of propellers under the varying conditions under which it has to work, due to rough sea.

It has for its object the automatic regulation of the screw, so as to prevent the too-rapid revolution or racing of the same occasioned by the screw being raised out of the water by the pitching of the vessel in an uneven sea.

It consists in regulating the amount of motive fluid supplied to the screw-engine and in applying a brake to the screw-shaft, both of which are operated by means of the devices hereinafter described and controlled by an electromagnet, the electric current for which is supplied by the closing of an electric circuit by means of a pendulum swung in such a manner as to be operatively susceptible to the pitching of the vessel.

In the accompanying drawings, in which like letters of reference denote like parts in the several figures, Figures 1 and 2 are side elevational views of the stern of a steam-propeller with a portion of the hull removed, showing in Fig. 1 the several parts of my invention, hereinafter described, in their relatively normal positions, or as when the screw is normally immersed in the water, and Fig. 2 showing the relative positions of the different parts of my device as when from the pitching of the vessel the screw rides out of the water. Fig. 3 is a cross-section taken as on the line 3 3 in Fig. 1, and Fig. dis a detached detail View of the direct application of the action of the electro-magnet to the throttlevalve without the intermediate mechanism shown in Figs. 1 and 2.

A represents the cylinder of the screw-engine, and B the shaft of the screw 0. To the shaft 13 is rigidly secured the brake-drum D.

Serial No. 377,977. (No model.)

F is operated by being secured on one end of the piston-rod G of the piston H, which is made to oscillate within the cylinder Iby the admittance of steam or other motive fluid above or below the piston H. To the piston H is also attached, so as to operatewith it, the rod K, which is adjustably connected with and operates lever to of the throttle-valve IV for controlling the supply of steam to the screw-engine.

The admittance of steam to the cylinder I above and below the cylinder H is controlled by means of the sliding valve M,'and this inturn is operated by the electro-magnet N, to which the operative current is furnished from the battery 0 by. closing the circuit P. The closing of the circuit P may be effected by circuit-closing devices automatically operated by the pendulum S, as hereinafter described. The pendulum S is pivotally mounted by being hung on the pivot-pin U, so as to swing in a plane parallel to the keel T of the vessel, and this pivot U is secured to the rockframe V, which has pivot-bearings at o o in a line parallel to the keel T of the vessel, whereby the frame V, and with it the pendulum suspended therefrom, is permitted a motion of revolution in a plane at right angles to the direction of the keel. The object of this is to permit the pendulum to always freely assume a perpendicularly-dependent position without i being influenced by the rolling of the vessel.

To the pendulum S is attached the arm 5, which carries on its end the two contact-m.aking springs a a. To the frame V is rigidly attached an arm, which terminates in the areshaped contact-plate Y, described from the center of the pivot-pin U as a center. To this frame V is also pivotally secured the adj ustable arc-shaped contact-plate Z, which is pivoted on a center corresponding with the pivot-pin U. i This contact-plateZ is electrically insulated from the rest of the frame V, and it is only when the contact-spring a touches it in the swing of the pendulum, the contactspring a always being in contact with the plate Y, that the circuit P is closed. The object of making the contact-plate Z adjustable is to make circuit for comparatively different degrees of movement of the pendul inn-as, for instance, might be required when the vessel is differentlyloaded and the screw leaves the Water with a proportionately-slighter pitch of the vessel.

"In Fig. t I have shown the armature-lever n of the magnet N connected to the throttlevalve lever by means of the connecting-rod n, so that any movement in the armature-lever a is transmitted directly to the throttlevalve WV. This arrangement may be found of advantage in cases when the shaft-brake can be dispensed with.

In operation, the circuit P being closed by the devices shown and described in the manner and for the reasons specified, the current from the battery 0 will instantly causethe armature of the magnet to be attracted. This willcause the armature-levern to operate the sliding valveM against the reactive tension of the spring 6, (to the position shown in Fig. 2,) so as to open the port 0% to the top of the cylinder H for the ingress of the motive fluid from some suitable source, as the boilers, from the pipe II, at the same time forming communication from the lower end of the cylinder through the port m to the open air. This will force the brake F against the drum D, which will tend to stop the rotation of the shaft B. In the downward movement of the piston H the rod K, secured to it, operates the throttle-valve'lever in, controlling the supply of steam flowing through the supply-pipe IV to the cylinder A of the screw-engine. When the vessel regains its normally-horizontal position, the pendulum S resumes its normal position, (that shown in opening the circuit,) and the tension-spring 6 will draw the armature-lever n and with'it the sliding valve M to the position shown in Fig. 1, which admits the steam to the under side of the piston I-I,

thereby relieving the drum D of the pressure of the brake F and turning on a full head of steam to the screw-engine cylinder A.

I claim-- 1. In devices for the regulation of propellers for steam-vessels, a throttle-valve for controlling the supply of motive fluid to the screwengine, and a brake capable of being applied to the screw shaft, said throttle-valve and said shaft-brake being operated by being mechanically connected with a piston, said piston being operated by motive fluid under the control of electric appliances, the operative current to said electric appliancesbeing furnished by closing an electric circuitby devices operated by contrivances susceptible of and capable of being actuated by the varying depths to which the stern of the vessel is immersed in the water, combined and operating substantially as described, and for the purposes specified.

2. In devices for the regulation of propellers for steam-vessels, the combination, with a throttle-valve WV and shaft-brake D, with piston H and piston-rods G and K, cylinder I, valve M, magnet N, circuit P, and battery 0, rocking frame V and attached rigid arm Y and adjustable arm Z, pendulum S, and pendulu m-ar1n s and attached contact-sprin gs aand a, operating substantially as described, and for the purposes specified.

3. In a marine governor, the combination, with a throttle-valve WV, of piston H, pistonrod K, cylinder I, valve M, magnet N, circuit P, battery 0, rocking frame V, having rigid arm Y and adjustable arm Z, and pendulum S, having arm 3, provided with contact-springs CL a, substantially as and for the purposes specified.

In testimony whereof I a ffix my signature, in presence of 'two witnesses, this 30th day of December, 1890.

ADOLIH HELLINGER.
