Description: |
| Most of the patents prior to 1836 were lost in the Dec. 1836 fire. Only about 2,000 of the almost 10,000 documents were recovered. Little is known about this patent. Only the patent drawing is available. This patent is in the database for reference only.
“The rudder head has a short tiller, projecting from it in the usual way. Within this tiller there is a metal nut to receive a screw of three threads, with which the vessel is to be steered. The screw revolves in stanchions, fixed upon the deck, in front of the rudder head. On one end of the screw, which is of iron, and about three feet long, a steering wheel is fixed; so that this part forms a wheel and axle. The screw passes through the nut in the tiller; which nut slides backwards and forwards in a groove, and swivels upon pins, like a compass box. This is the whole arrangement.
To us the plan appears to be inferior to some already in use, on several accounts; particularly, as it seems impossible to put the helm hard up. If steering with a screw in this way, is found to be eligible, we apprehend that a toothed segment on the rudder head, would be far preferable to the sliding nut.”
