I GEORGE. WILLIAM GREEN of Dunedin New Zealand Factory Foreman do
hereby declare the nature of this invention and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:
My Invention is designed to construct oars or sweeps combining strength with
lightness and cheapness and the facility of renewing the parts of the same, and
has for its object the adoption of a metallic blade and a metallic adjustable
rowlock band and feathering flange or vane.
Referring to the accompanying sheet of drawings and to the figures and letters
of reference marked thereon.

Fig. 1 is a side elevation of my complete oar or sweep.
Fig. 2 side elevation of a loom.
Fig. 3 edge view of Fig. 1.
Fig. 4 enlarged section across the rowlock band.
Fig. 5 side elevation (enlarged) of the rowlock band.
Fig. 6 enlarged section on line E F fig. 1.

Fig. 8 enlarged section on line A B fig. 1.
According to my invention I use a wooden loom A having à suitably shaped
handle B and a tapered squared end B' for affixing thereto the metallic blade C.
This I make of metal in one or more pieces, rivetted-or-bolted-together-and-nipping
the square tapered end of the loom A as shewn in fig. 5 the end of the loom
gradually tapering away as shewn-in-fig.-S. but generally the latter. Around and
along the edges of the blade at D, Figs. 1. 7 and 8, the metal of the outer side or
back of the our or scull would be turned up, about at right angles thereto, so that
the inner-side plate or front of the our would lie therein, when the said edges of
the outer plate would be turned down all around and soldered to the inner plate,
thus uniting the two plates together. This joint may however be made without
the metal of the plate being turned over, as for instance, the two plates may be
simply made level with each other at their edges, and then soldered or otherwise
fastened to each other.
The two bent pieces of sheet metal forming the blade C. are united at their
edges D by rivetting brazing or otherwise. and the blade may be screwed-to-the
laam.as.in.fic a

page_text: The tapered end of the loom B¹ Fig. 2 would be made to pass as fur into the
socket as practicable, the farther the better, and in most cases this would have
sufficient holding power or nipping power to keep the blades thereon for use, but
I may use screws as shewn at D Fig. 3, or any other device to secure the blades to
the handles or looms, should it be necessary.
I preferably oval the loom towards its junction with the blade C as shewn in the
cross section Fig. 6.
I substitute for the usual leather rowlock band and button, which in its applica-
tion is a source of weakness to the loom the device shewn as follows E is a metal
cap or clip preferably which may be in two portions having flanges F F capable
of being clamped together by screws G G (three are shewn) the cap or clip passing
round a suitably shaped portion of the loom to receive the same and so that the
said cap or clip may be suitably adjusted longitudinally thereon.
Integral with or attached to the said clip or cap E is a feathering flange or
vane H shaped similarly as shewn and for bearing on the rowlocks or thole pins
of the boat or vessel for guiding the oar or sweep in its feathering movement the
flange or vane H being so shaped as to direct the feathering stroke of the oar or
sweeper. It will be seen that if the metallic blade of my oar or sweep be damaged
or bent it can readily be removed for repair or renewal and that the metal cap or
clip E and feathering flange or vane H can be readily removed by slackening the
screws G G G or adjusted along the loom A to vary. the leverage or fulcrum of the
oar or sweep for different sized boats or vessels.
The blade of the oar or loom sweep can be made of steel, phospor bronze "Delta-
metal" or any other suitable material metal likewise the cap or clip E and the
flange or vane H and the flange or vane H can be covered with leather or like
material the cap E and its flange or vane Ḥ can be fitted to the ordinary wooden
oars or sweeps if desired as an attachment, the usual wooden blade being employed.
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
Firstly. The improved, construction of oar or sweep substantially as described
and illustrated by the accompanying drawings.
Secondly. In an oar or sweep the combination of a wooden loom, a metallic blade
fitted thereto and a cap or clip embracing the loom and carrying a feathering flange
or vane forming the fulcrum of the oar or sweep substantially as described.
•
Thirdly. Applying to the loom of an oar or sweep a metal cap or clip such as E
embracing the loom and longitudinally adjustable thereon if desired, such cap or
clip carrying a feathering flange or vane such as. H substantially as and for the
purposes desired.
