Year: 1884

page_text: PROVISIONAL SPECIFICATION.
I, JOHN WILLIAM HALLMAN of 15 Commercial Street Middleton West
Hartlepool (Shipbrokers) Waterclerk, do hereby declare the nature of my Invention
for IMPROVEMENTS IN BOATS' ROWLOCKS to be as follows:-
The rowlocks to be cast of brass or made from wrought iron to be afterwards
galvanized, as required. The rowlock is worked on a swivel in a socket which in
shipping is self locking falling as it does between the two shoulders of the angle
brass or iron to which it is fastened by means of a crosspin at the bottom of the
Bocket which works in the two holes in the angles. The angles are screwed or
bolted fast to the gunwale. The rowlock is instantly unshipped by lifting up the
socket, and as easily reshipped by lifting the socket up again.

page_text: JOHN WILLIAM HALLMAN of 15 Commercial Street Middleton West Hartlepool,
Shipbrokers Waterclerk do hereby declare the nature of my Invention for
IMPROVEMENTS IN BOATS ROWLOCKS and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
To be made of brass or wrought galvanized iron as ordered. The rowlock
works on a swivel in a socket, is self locking, and being fixed between two
hanging pieces bolted to the gunwale cannot be lost. The rowlock can be raised
into position (locked). or dropped (unlocked) instantly.
In order that my Invention may be more clearly understood, I shall now proceed
to describe it with reference to the accompanying Drawings in which the same
letters refer to corresponding parts in the several views.
Figures 1. 2 & 3 respectively shew side, and end elevations and plan of rowlock
when "shipped." A is the rowlock which swivels in the socket B. so formed that
it may slip behind top of guide-brackets E. bolted to the gunwale of boat F and
carrying a tailpiece provided with two pins D working in slots in the guide
brackets E. The socket B is held in position by pins & sliding in slots in the
guide-brackets above pins D on tailpiece, the pins G being on bridgepiece H which
has a' projection capable of being hooked in under the gunwale.
The rowlock is "unshipped" as shown in Figures 4. 5 & 6 by unhooking
bridgepiece H and lifting socket B until clear of the top of guides E when it can
be swung over and allowed to hang against the side of the boat and may be
secured in that position by again hooking the bridgepiece under gunwale.
Having now particularly described and ascertained the nature of my Invention
and in what manner the same is to be performed, I declare that what I claim is :-
The combination of a swivelling rowlock with a socket sliding behind top of
guide brackets secured to gunwale of boat and having a tailpiece guided between
the brackets which carries at its lower end pins engaging in slots in the guide-
brackets the socket being held in position by pins which project from a bridgepiece
into the slots above the pins on end of tailpiece of socket, the said bridge piece
having a projection which can be hooked under gunwale-the whole substantially
as described in Specification and shewn on accompanying Drawings.
Dated this 10th June 1884.
