IMPROVEMENTS IN PUMP GEAR FOR FISHING SMACKS AND SUCH LIKE VESSELS
Year: 1884

page_text: We JAMES PLASTOW and EDWARD RICHARDSON both of Fish Docks Grimsby
Fish Salesmen do hereby declare the nature of our invention for "IMPROVEMENTS
IN PUMP GEAR FOR FISHING SMACKS AND SUCH LIKE VESSELS." to be as follows:-
This Invention has for its object improvements in pump gear for fishing smacks
and such like vessels.
In vessels of this class serious loss of life occurs from the necessity for coming
on deck in rough weather to work the pump.
The gear which I will proceed to describe admits of the pumps being worked
from below, either by steam power or by manual labour.
A pair of pump cylinders are inserted into openings provided for them in the
deck of the vessel so that the water may be delivered from them on to the deck of
the vessel as is usual.
Between the pump cylinders a frame is fixed upon the deck and in it a slide is
fitted to move vertically.
The slide has a cross head formed upon it, and rods carrying the pump buckets
descend from the cross head one at either end.
Another rod descends from the centre of the slide through the deck by an
opening which is rendered watertight by a packed gland.
This rod receives movement by a connecting rod from a crank axis below the
deck, or an eccentric may be employed in place of a crank.
The axis can be driven by means of the steam engine employed in getting the
nets; or when the steam is not available or where a steam engine is not provided
the pumps can be worked from below deck by means of a hand lever.
Dated this 2nd day of January 1884.

Another rod descends from the centre of the slide through the deck by an
opening which is rendered watertight by a packed gland.
This rod receives movement by a connecting rod from a crank axis below the
deck, or an eccentric may be employed in place of a crank.
The axis can be driven by means of the steam engine employed in getting the
nets; or when the steam is not available, or where a steam engine is not provided
the pumps can be worked from below deck by means of a hand lever.
In order that our said invention may be most fully understood and readily
carried into effect we will proceed to describe the drawings hereunto annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a longitudinal section showing the general arrangements in a fishing
smack to which our invention is applied.
Figure 2 is a side elevation to a larger scale of a portion of the pump gear.
Figure 3 is a front elevation partly in section of the same.
A A are two pump cylinders, they pass through the deck of the vessel and
communicate at their lower ends with suction pipes which descend to the bilge.
B is a standard fixed to the deck between the two pump cylinders.
C is a slido capable of moving up and down in the standard B. This slide is
made in two parts bolted together and each part carries an arm to which the rod
carrying one of the pump buckets is attached. The two parts of the slide also
embrace and are firmly connected with another central rod D, which passes down
through a stuffing box E in the base of the standard A to the underside of
the deck.
F is the cover of this stuffing box; when in place it is held down by bolts, but
the drawing represents this cover as somewhat raised in order that it may be more
clearly scen.
The lower end of the rod D is jointed to a connecting rod G which at its lower
end is connected with a crank pin upon the engine shaft H. The engine is
arranged in the manner usual in these vessels, and it drives the capstan I, which is
employed in getting the nets and in doing other work on board the vessel.

page_text: K is a hand lever which is provided for working the pumps when the steam
power is not available; it has a rocking fulcrum at K¹, and it is jointed at K² to
the rod D.
When the hand lever is to be employed the rod D is unjointed from the
connecting rod G, and the hand lever is connected up in its place."
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed, we declare that what
we claim is
First. Our improvements in pump gear for fishing smacks and such like vessels
consisting in connecting the pump buckets with arms upon a slide which is able to
move up and down in a standard on the deck and is actuated by means of a rod
passing down from the slide down to the underside of the deck, where it receives
motion either by steam or by manual labor, substantially as herein described.
Second. Our improved pump gear for fishing smacks and such like vessels
substantially as herein described.
