City of Westminster, for the Invention of "IMPROVEMENTS IN PUMPS."
PROVISIONAL SPECIFICATION left by the said Leonce Pierre Othon at the
Office of the Commissioners of Patents on the 11th November 1876.
LEONCE PIERRE OTHON, of 8, Victoria Chambers, in the City of Westminster.
"IMPROVEMENTS IN PUMPS."
This Invention has for its object improvements in pumps.
The pump consists of a flexible india-rubber tube inserted along the inside of a
segment of a circular frame made of wood or metal. The frame carries an axis on
which are fixed cross bars having at their ends rollers, and the working of the
pump is produced by turning a handle which rotates the axis and cross bars. The
rollers at their extremities come in succession against the tube so as to flatten it
against the segment of the frame. The segment of the circular frame upon which
the tube is, is a little longer than the distance between the rollers, so that the action
of the next roller may be brought to bear upon the tube before the other has left or
ceased acting.
By means of the expulsion of the air from the tube suction is produced, and the
forcing effect is produced by the following rollers acting upon the tube; the action
is very powerful although a comparatively small force is required to work the
machine.
The pump has also the recommendation that it can be easily transported from
place to place, and can be fixed ready to work without expense. There are no
valves and the pumps can be made of any size.

IMPROVEMENTS IN PUMPS."
This Invention has for its object improvements in pumps.
The pump consists of a flexible india-rubber tube inserted along the inside of a
segment of a circular frame made of wood or metal. The frame carries an axis on
which are fixed bars or arms having at their ends rollers, and the working of the
pump is produced by turning a handle which rotates the axis and bars. The rollers
at their extremities come in succession against the tube so as to flatten it against
the segment of the frame. The segment of the circular frame upon which the tube
is, is a little longer than the distance between the rollers, so that the action of the
next roller may be brought to bear upon the tube before the other has left or ceased
acting.
By means of the expulsion of the air from the tube suction is produced, and the
forcing effect is produced by the following rollers acting upon the tube; the action
is very powerful although a comparatively small force is required to work the
machine.
The pump has also the recommendation that it can be easily transported from
place to place and can be fixed ready to work without expense. There are no
valves and the pumps can be made of any size.
In order that my said Invention may be most fully understood, and readily
carried into effect, I will proceed to describe the Drawing hereunto annexed.
DESCRIPTION OF THE DRAWING.
The Drawing represents an elevation of a pump constructed according to my
Invention.
a is a standard, which by means of screws or otherwise can be fixed to a post or
other suitable support; it carries an axis b capable of being rotated either by a
handle or in other convenient way; c, c, are arms fixed upon the axis b, they are
forked at their outer ends, and each of them carries a roller d which is free to turn
upon a pin or axis. The standard & has cast with it the circular segment e; this is
of trough-like section, and the vulcanized india-rubber tube flies within it. There
is a hole at each end of the segment c, and the india-rubber tube passes by these
holes from the exterior to the interior. The lower end of the india-rubber tube
serves as the suction of the pump, and the upper end as the delivery, and where
desired it may terminate in a nozzle adapted to throw a jet. As the axis o revolves
the rollers & come in succession into contact with the tube f and collapse it so that
water cannot pass the point of pressure, and one roller does not travel off the tubo
until that which follows has closed the tube behind it.
Having thus described the nature of my said Invention, and the manner of per-
forming the same, I would have it understood that I claim as my Invention of
improvements in pumps the combination of the parts a, b, c, d, e, and f, substantially
as described.
In wituess whercof, I, the said Leonce Pierre Othon, have hereunto set my
hand and seal, this First day of May, in the year of our Lord One thousand
eight hundred and seventy.seven
