PROVISIONAL SPECIFICATION.
Improvements in and relating to the Rowlocks of Boats, Dingeys,
and the like.
I, MURRAY PRESTON, of William Street, Deritend, in the City of Birmingham,
Manufacturer, do hereby declare the nature of this invention to be as follows:-
This Invention consists of improvements in and relating to the rowlocks of
boats, dingeys, and the like, my object being to provide means whereby the
rowlocks shall the more readily and easily adapt themselves to the varying positions
of the oars.
My invention comprises the employment of balls or rollers interposed between
the rowlock and the carriage or fixture in which it is placed.
In the construction and arrangement of a rowlock in accordance with my inven-
tion in one convenient manner, I fit the stem with hardened cones or bearing
surfaces, and the carriage in which the rowlock is placed I fit with hardened
cups or bearing surfaces, and between the cones and cups or the bearing surfaces
of the rowlock and carriage I place halls or rollers, enabling the rowlock to move
freely and thus to readily adjust itself to the movement of the oar.
I provide for the adjustment of the cones and cups or the ball or roller bearing
surfaces in any convenient manner, and modify the arrangement of the parts to
meet the requirements of varying services.
