Improvements in Rotary Pumps.
I, ALBERT PERCIVAL KILPATRICK, of 21 Rectory Square, White Horse Lane,
Stepney, in the County of Essex, Engineer, do hereby declare the nature of this
invention to be as follows:-
My invention relates to improvements in rotary pumps, which consists of a suitable
shaped flanged box or cylinder with flanged covers, and to each cover is formel
projecting bearings in which a horizontal spindle revolves. At the top of the box or
cylinder on the left hand side is the delivery port and below the level of the said
delivery port on the right hand side of the box or cylinder is the suction port. At the
back of the delivery port inside the box or cylinder is a small chamber and in this
said chamber is a flat roller or disc which rises and falls as the shaped disc on the
horizontal spindle revolves.
The disc on the horizontal spindle has two opposite projections which travel round
the water space in the box or cylinder, each projection forcing the roller (or valve)
upwards to pass the water into the delivery port, the said roller falling again on the
disc into the water space.
The spindle is driven by a handle or a pulley.

page_text: My invention consists of a suitably shaped flanged box or cylinder a with flanged
covers, and on each cover is formed a projecting bearing e in which a horizontal
spindle d revolves. At the top of the box or cylinder a on the left hand side is the
delivery port e and below the level of the said delivery port e on the right hand side
of the box or cylinder a is the suction port f. At the back of the delivery port e
inside the box or cylinder a is a small chamberg and in this said chamber is a flat
roller or disc which rises and falls as the shaped disc or revolving centre i on the
horizontal spindle d revolves.
The disc or revolving centre i on the horizontal spindle has two opposite pro-
jections which travel round the water space in the box or cylinder a, each
projection j forcing the roller h (or valve) upwards to pass the water into the delivery
port e, the said roller falling again on the disc or revolving centre i into the
water space.
The spindle d is driven by a handle or a pulley.
The travel of the water from the suction port through the water space k in the
flanged box or cylinder a and out at the delivery port e is indicated by arrows both
in Figs. 1, and 3.
If preferable as in Figs. 3, and 9; I construct a flanged box or cylinder a with
a differently shaped flange m and a well n at the base. Above the well n there is an
opening or slot o. The shaped dise or revolving centre is provided with movable
blades p resting on india rubber or any other springs q so that as the ends of the
blades wear away the springs a force the said blades forward so as not to impede
the action of the pump.
At each end of the shaped disc or revolving centre I cut a circular groover and in
this said groove r I place a ring s which fits into a corresponding groove cut in the
adjacent cover.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. In rotary pumps, the combination of the various parts of the apparatus
constructed in the manner described in the above specification for the purpose
specified.
2. In rotary pumps, the combination of the flanged box or cylinder a flanged
covers projecting bearings c spindle d delivery port e suction port chamber g
roller revolving centre projections ; water space k and handle 1, substantially
as herein described and according to Figs. 1, 2, 4, 5, 6, 7, and 8, of the accompanying
drawing.
3. In rotary pumps, the combination of the flanged box or cylinder a flanged
covers b projecting bearings c spindle d delivery port e suction port f chamber g
roller revolving centre projections ; water space k handle flange m well n
opening or slot o movable blades p india rubber or other springs a circular grooves r
and rings s, substantially as herein described and according to Figs. 2, 3, and 9, of
the accompanying drawing.
