Application filed August 27, 1924. Serial No. 734,485.

To aZZ whom it may concern:

Be it known that l, VIc'ron VJARVINEN, a citizen of the United States, residing at Astoria, in the county of Clatsop and State of Oregon, have invented certain new and useful Improvements in Rudder-Shaft Bearings, of which the following is a. specification.

This invention relates to boats of various kinds more particularly to the smaller class of motor driven boa-ts employed in industrial pursuits such as fishing, or hunting, and in pleasure boats, and the like, and has for one of its objects to provide an improved means for supporting the rudder post of the boat, to protect the same from the action of sand and grit, and to prevent sand and grit from lodging in the step of the post.

With these and other objects in view the invention consists in certain novel features of construction as hereinafter shown and de- Figure 3 is a transverse section of the same.

The improved device may be applied without material structural change to motor driven boats of various sizes and forms, and it is not desired to limit the invention in any manner in this respect, but for the purpose of illustration is shown applied to a conventional boat of this class, the hull or body being represented at 10 with an overhanging stern portion 11, and the propeller at 12.

Attached to the keel portion of the hull 10 is a shoe element 13, the latter extended rearwardly of the stern post- 14: and connected at its rear end by a brace 15 to the overhang 11, as shown.

Attached to the upper face of the shoe 13 is a step device, represented as a whole at 16 with an upwardly arching bottom portion 17 and an upwardly directed socket 18 communicating at its lower end with the arching portion. The arching portion extends entirely through the step from side to side, so thatthe water flows freely therethrough and effectually prevents the sand, grit and the like from settling in the step or its socket.

The rudder of the boat is represented at 19 and the rudder post at 20, the latter eX- tending at its lower end below the lower line of the rudder and engaging the socket 18 of the step and bearing by its lower end on the upper face of the shoe 18, as shown more clearly in Figures 2 and 3.

A part of the lower end of the post 20 is thus constantly exposed to the flow of the water through the arching portion of the step, andall the tendency of sand grit or the like to settle in the socket and engage F the post is obviated. The post is thus effectually protected against abrasion or wear from this source, and its life thereby prolonged.

The improved device is simple in construction, can be inexpensively manufactured, and preferably of cast iron, which effectually resists the'action of salt water.

The preferred embodiment of the invention is disclosed in the drawings and set forth in the specification, but it will be understood that modifications within the scope of the claimed invention may be made in the construction without departing from the principle of the invention or sacrificing any of its advantages.

Having thus described the invention, what is claimed as new is:

1. An attachment for vessels comprising a shoe element adapted to be attached to the bottom of the keel and extending rear wardly of the stern post of the vessel, a brace connected at one end to the rear end of the shoe and adapted to be coupled at the other end to the body of the vessel, a step attached to the shoe with its lower face having an upwardly arching portion and with a socket communicating with the arching portion, said socket adapted to receive the post of the rudder of the vessel with the lower end of the post bearing on the shoe beneath the socket, and said arching port-ion open at the sides and providing a channel through the step to prevent the lodgement of matter against the post.

2.]An attachment for vessels comprising a shoe element .adapted to be attached tothe bottom of the keel and extending rearwardly of the stern post of the vessel, a

step attached to the shoe with its lower face having an upwardly arching portion and with a socket communicating with the arching portion, said socket adapted to receive the post of the rudder of thevessel With the lower end of the post bearing on the shoe beneath the socket, and the arching portion open at the sides and providing an open channel tl'irough the step to prevent the lodeernent of matter against the post.

3. An attachment for vessels comprising a step for a rudder post adapted to be attached to the vessel and including a socket and an upwardly arching portion providing a channel through the step to prevent the lodgement of matter against the post.

In testimony whereof, I affix my signature hereto.

VICTOR JARVINEN.
