SPECIFICATION forming part of Letters Patent No. 652,052, dated June 19, 1900.

Application tiled February 18, 1899. Serial No. 706,006. (No model.)

To cil/ZZ whom t may concern;

Be it known that we, CARL VICTOR SUP- PN, residing at Vienna, in the Province of Lower Austria, and BLA SZENDI, residing at Buda-Pesth, in the Kingdom of Hungary, E1npire of Austria-Hungary, subjects of the Emperor of Austria-Hungary, have invented certain new and useful Improvements in Steering Devices for Ships; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and'use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention has relation to steering-gear for ships; and it has for its object the provision of means whereby the shifting and holding fast of the helm or steering-wheel can be effected with the least possible exertion or ap- To this end the steering- Wheel spindle from which power is transmitted to the barrel on which the rudder-chain is wound is connected, by means of suitable gearing, with a weighted lever, which when the steering-Wheel is in the amidship position stands on its dead-point above its axis of rotation, and hence exerts no power on the steering-wheel spindle and therethrough on the rudder-chain barrelA and rudder. When, however, the steering-wheel spindle is revolved in one or the other direction, the weighted lever is moved out of its dead-point through the connecting-gearing and at once exerts power upon said spindle and therethrough upon the rudder. The power exerted by the lever is in direct ratio to the increase of the deviation of the rudder, and consequently in direct ratio to the forces to be overcomenamely, the power exerted by the water on the rudder.

That our invention may be fully understood, we will describe the same, reference being had to the accompanying drawings, in Which- Figures l and 2 are side and end elevations, respectively, shown partly in section; and Figs. 3 and 4 are side and endelevations, respectively, also shown partly in section, of a slight modicat-ion in the arrangement of the with a sprocket-wheel b2 on the spindle that carries the barrel b for the rudder-chain b. The pinion c3 meshes with a gear-wheel CZ on spindle S,which also carries a pinion d', in gear with an irregular or cam-shaped gear-wheel d2 on spindle s@ Said cam-shaped gear d2 meshes with an irregular or cam-shaped gear d3 on spindle f', that carries the weighted lever f.

As hereinbefore stated, when the rudder isi in a normal position or amidship the weighted lever f is on its dead-point above its fulcrumspindle f, as shown, while the interrneshing parts of the cam-shaped gears d2 d3 are, as shown, of such contiguration that when the steering-wheel spindle is rotated in one or the other direction, whereby the lever f is carried over its dead-point, said lever will exert .a gradually-increasing power on said steering-wheel spindle and therethrough on the rudder-chain barrel and rudder, which power is in direct ratio to the deviation of the rudder from its amidship position, and hence in direct ratio to the power exerted by the water on said rudder, as hereinbefore stated, thus enabling the steersman to steer the ship with the least possible exertion on his part. In practice the weight f 2 on lever f is made adjustable lengthwise of the lever by any of the ordi-nary means used for this purpose, so that the power exerted by the lever can be regulated in accordance with the speed of the ship and the varying forces exerted by the water on the rudder resulting from speed variations.

The described steering-gear may of course be variously modified in so far as the relative arrangement of parts is concerned to suit the conditions of use. Thus, for instance, the

rudder-chain barrel may in some cases re- IOC quire to be located above the after or steering deck. In this case we mount said chainbarrel b on the steering-wheel spindle 011, as shown in Figs. 3 and 4, and We may locate the weighted lever f at some point distant from said apparatus--as, for instance, below the after or steering deck or wheel-house, as shown in said Figs. 3 and 4.

The arrangement of the gearing through which the power is exerted by the Weighted lever f on the steering-wheel spindle c is substantially as shown in Figs. l and 2. The pinion cS1 on steering-wheel spindle 011 Vmeshes with a gear-wheel d. on spindle s11,which carries the pinion C121, in gear with the cam-shaped gear (Z22 on spindle S21, which cam-gear meshes with cam-gear dss on spindle ff. When I[he weighted lever f H is located below the steering apparatus, then the spindle fm, that carries the cam-shaped gear ds, has secured on either v side of said camgear a crankf, connected by rods f6 with cranks f4 on the fulcrum-spindle fi, on which the weighted lever fu is mounted, said fulcrum-spindle having its bearings in a suitable stand f3, as clearly shown.

The operation of the steering-gear when modified in its arrangement is the same as hereinbefore fully set forth.

We claim- 1. In a steering-gear for ships, the combination with the rudder and steering appliances, of means for balancing or substantially balancing the forces of resistance transmitted nation with the rudder and steering mechanism, of appliances for balancing the forces of resistance transmitted to said mechanism through said rudder, said appliances organizedV to vary the power of the steering mechanism in accordance with the variations of Vsaid forces of resistance, substantially as s'et forth.

4. In a steering-gear for ships, the combination with the rudder, the steering-wheel spindle and the rudder-chain-winding drum or wheel geared to said spindle; of abalancing-weight displaced by the rotationl of the steering-wheel spindle and operating to balance or substantially balance the forces of resistance transmitted through the rudder to the steering-chainand winding-drum, for the purposes set forth.

5. In a steering-gear for ships, the combination with lthe steering mechanism, of the two intergeared cams d2 (Z3, transmitting-gearing connecti-ng cam d2 with the steering-spindle, and a weighted lever, the fulcruln-spindie of which is connected with and revolved by cam d3, substantially as and for the purposeset forth.

6. In a steering-gear for ships, the combination with the steering-wheel spindle and the steering-chain-Winding drum geared to said spindle, of the two intergeared cams d2 d3, transmitting-gearing connecting cam d2 with said steering Wheel spindle, and a Weighted lever on .the spindle of cam d3, substantially as and for the purpose set forth.

In testimony that we claim the foregoing as our invention we have signed our names in presence of the ysubscribing witnesses.
