the descent of water during a temporary stoppage of pumping. The valves and
the sides of the valve chauber may be constructed of slate, stone, earthenware or
other durable material not liable to warp or contract.
Except the spindles, bolts and screw-pins which are of copper, the remaining
parts may be of wood, and provided at such places as may be desirable with a
binding of copper or other metal not liable to corrode. The action of the pump is
easy and powerful and the construction is economical.

WILLIAM BULLOCK TIBBITS of Clifton in the County of Gloucester AN
IMPROVED PUMP
This invention relates to an oscillating pump which is adapted for use on board
ship and specially on board of such vessels and in such places where only manual
power is available for working pumps.
Through the upper part of the body of the pump or valve chamber, which, in
form, is a segment of a cylinder, passes an axis or shaft upon the ends of which
projecting through the sides of the chamber, are fitted the pump levers, one on
each side of the chamber, and braced or transversely tied together at their ends.
Upon the portion of the shaft embraced within the valve chamber is fixed a
pair of radiating paddles or arms resembling a bell-crank, and in cach paddle or
arm is formed a valve or flap free to open upwards. Extending across the valve
chamber, and underneath the shaft or axis aforesaid, is a block of wood or other
desired material forming a partition between the radiating paddles or arms.
At
or near the underside of this partition are placed two valves which radiate from
the same spindle or pivot in such inanner that each half of the throat of the pump
is alternately opened and closed by these valves which are formed to mutually
assist one another in the action of closing.
When, by the actuation of the pump levers, the right hand paddle is caused to
rise, the valve or flap therein becomes closed and a vacuum being produced in the
space between the paddle and the throat valve which admits the water from the
pump barrel or tube to that space, this throat valve opens and the aforesaid space
becomes filled with water. Simultaneously, in the descent of the left hand paddle
or arm, the left hand throat valve being closed, the water occupying the space
between it and the corresponding paddle escapes through the open valve or flap in
the latter to the upper side thereof, whence it is, on the return motion of the
paddle, ejected through an aperture or mouth at or near the top of the body of the
pump.
On the return motion of the levers, the valve or flap of the right hand paddle
opens and, the corresponding throat valve being closed, the water passes through the
valve or flap in the paddle and is, in like manner, subsequently ejected. The valve
or flap in the left hand paddle becomes closed and the corresponding throat valve
becomes open, as herein before described with reference to the right hand.
And in order that the said invention may be properly understood, I now proceed
more particularly to set forth, by reference to the accompanying sheet of drawings
and to the figures and letters marked thereon, the mode or manner in which the
same may be used or practically carried into effect.
Fig. 1 on the accompanying sheet of drawings represents a side elevation
of an example of my improved pump. Fig. 2 is an end view, Fig. 3., a vertical
section and Fig. 4., a transverse vertical section. Fig. 5., is a horizontal
section of the valve chamber K, immediately above the throat valves E. E'.
Through the upper part of the body or valve chamber K of the pump which
is, in form, a segment of a cylinder, passes an axis or shaft A, upon the ends
of which, projecting through the sides of the chamber, are fitted the pump
levers N. N. braced or tied transversely together at their ends as shown. Upon
the shaft A, and within the chamber K, is fixed a pair of radial paddles B, B¹,
resembling a bell-crank, and in each paddle or arm is formed a valve or flap, C

page_text: and C' respectively, free to open upwards. Extending across the valve chamber K,
and situated underneath the shaft A, is a block D, of wood or other desired material,
forming a partition between the radial paddles or arms B, B'. Below the partition D
are placed two valves E, E' which radiate from the same spindle e in such manner
that each half of the throat a of the pump is alternately opened and closed by
these valves which are formed to mutually assist one another in the action of
closing.
When, by the actuation of the pump levers N, N₁, the paddle B is moved upwards
on the axis A, the valve or flap C therein becomes closed and, a vacuum being
produced between the paddle B and the throat valve E, this latter is caused to open
and admits water to the intervening space. Simultaneously, in the descent of the
paddle B', the throat valve E' being closed, the water occupying the space between
this valve and the paddle B' escapes through the open valve or flap C₁ to the upper
side thereof, whence it is, on the return or upward motion of the paddle, ejected
through the aperture m¹ and sluice or door M¹ at or near the top of the valve
chainber K.
On the return motion of the levers N, N', the valve or flap C of the paddle B
opens and, the throat valve E being closed, the water passes through the valve or
Hap C and is, in like manner, subsequently ejected through the aperture m and
sluice or door M. The valve or flap C₁ becomes closed and the throat valve E¹
becomes open as herein before described with reference to the paddle B and the
corresponding flap and throat valves.
The pump barrel or tube G may be a fixture in the hold of a ship and may thus
serve as a ventilator when not required for raising water. The pump may be
readily unshipped from the tube, the junction being maintained between it and the
lower part F of the neck of the valve chamber K by means of the movable
frame or trestle 0 in which the valve chamber and contained mechanism is
supported and carried. A throttle or tipping valve H placed in the tube G prevents
the descent of the water during any temporary cessation of pumping.
The valves C, C, E, E¹ and H, and the flat sides of the valve chamber K, as
also a portion of the segmental part L of the same (see Fig. 2) may be made of
slate, earthenware or other material not liable to warp or unduly contract or
expand.
Except the spindles, bolts and screw pins which are preferably made of copper,
the remaining parts may be of wood and may be strengthened at such places as
may be desirable by a binding of copper or other metal not easily corroded.
The construction of the pump is simple and economical, the action is reciprocating
and powerful and the discharge is unintermittent.
Having now described and particularly ascertained the nature of the said
invention and the mode or manner in which the same may be used or practically
carried into effect, I claim as the invention secured to me by the herein before in
part recited Letters Patent.-
The arrangement and construction of the frame and mechanism constituting the
pump substantially as described and shown upon the accompanying sheet of
drawings.
In witness whereof, I, the said William Bullock Tibbits, have hereunto set
my hand and seal, this thirteenth day of December in the year of our Lord
