IMPROVEMENTS IN THE CONSTRUCTION OF ROWLOCKS FOR BOATS
Year: 1885

page_text: I GEORGE HUGHES of Temple Works, Temple Street, Wolverhampton in the
County of Stafford, Wrought Ironwork Manufacturer do hereby declare the nature
of my Invention for "IMPROVEMENTS IN THE CONSTRUCTION OF ROWLOCKS FOR
BOATS" to be as follows: -
The object of my invention is to manufacture rowlocks for boats in an improved
manner, and so as to obviate the necessity for using chisels in fixing the plates for
the same.
My improved rowlocks are usually formed of wrought iron, but any other
suitable material may be used, if preferred.
The jaws and spindle are formed in one piece. The upper part of the spindle,
(where it joins the jaws) is made conical; the large end of the frustum being
upwards, next to the jaws. The lower end of the spindle is provided with an eye,
as usual.
The plate in which the spindle works, and which is fitted to the gunwale,-is
formed in segments of circles, so that in fitting a chisel is dispensed with, and drills
or centre-bits only are required to form the holes for the screws and spindle.
The central hole in the plate is made conical to fit the conical head of the
spindle. The latter fits the conical hole in the plate, and the action of the
rowlock, when in use, renders the fit continually perfect, by grinding the surfaces
together.

J, GEORGE HUGHES, of Temple Works, Temple street, Wolverhampton, in the
County of Stafford, Wrought iron-work- Manufacturer, do hereby declare the nature
of my invention for IMPROVEMENTS IN THE CONSTRUCTION OF ROWLOCKS_FOR
BOATS, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
The object of my invention is to manufacture rowlocks for boats in an improved
manner, and also to obviate the necessity for using chisels in fixing the plates for
the same.
My improved rowlocks are usually formed of wrought iron, but any other
suitable material may be used, if preferred.
The jaws and spindle are formed in one piece. The upper part of the spindle,
(where it joins the jaws) is made conical; the large end of the frustum being
upwards, next to the jaws. The lower end of the spindle is provided with an eye,
as usual.
The plate in which the spindle works, and which is fitted to the gunwale, is
formed in segments of circles, so that in fitting a chisel is dispensed with, and drills
or centre-bits only are required to form the holes for the screws and spindle.
The central hole in the plate is made conical to fit the conical head of the
spindle. The latter fits the conical hole in the plate, and the action of the
rowlock when in use renders the fit continually perfect, by grinding the surfaces
together.
And in order that my said invention may be particularly described and ascertained,
reference is hereby made to the accompanying drawing, in which similar letters of
reference indicate corresponding parts.
Fig. 1 is an elevation of the spindle a, cone b, and jaws c c. Fig. 2. is a section,
and Fig. 3 a plan of the socket plate. d is a hole as usual. b¹ is the conical socket
in the plate, e e are countersunk holes for receiving the screws, by which the plate
is secured in the gunwale.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
The manufacture and use of rowlocks for boats having conical bearing surfaces
and sockets with bearing plates so formed as to be readily fitted, substantially as
hereinbefore described and shewn on the drawings.
