PROVISIONAL SPECIFICATION.
Improvements in Boiler and Ram Pumps.
We EDMUND STANSFIELD, Mechanic, of 4 Springfield Cottages, Morley, near
Leeds and JESSE GRAHAM, Engineer, of 5 Springfield Cottages, Morley, near
Leeds do hereby declare the nature of this invention to be as follows:-
Our invention consists of a combined slide and packing case with rings to
dispense with ordinary hemp or cotton packing in boiler and ram pumps generally.
The boiler pump consists of a solid or hollow ram working in a barrel, and this
ram must be made water tight and our invention is to make this ram work without
leakage by means of rings sprung into grooves in the ram and the rings working
against the side of our circular combined slide and packing case which makes the
pump work without leakage of water.

COMPLETE SPECIFICATION.
Improvements in Boiler and Ram Pumps.
We, EDMUND STANSFIELD, Mechanic of 4 Springfield Cottages Morley, near
Leeds, and JESSE GRAHAM, Engineer, of 5, Springfield Cottages, Morley aforesaid,
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:
This invention has for its object the construction of boiler and ram pumps in
such a manner that, hemp and cotton packing applied in stuffing boxes in the
manner as hitherto may be dispensed with, and in lieu thereof, to practically
prevent the escape of liquid from the pump barrel by metallic rings inserted in
grooves in the ram or plunger working in an additional barrel secured to the top
of the pump..
In describing our invention in detail, reference is made to the accompanying
drawing representing the section of a portion of an ordinary boiler or ram pump,
with our improvement added thereto also in section.
The boiler pump A, is of the ordinary construction provided with a space B,
similar to an ordinary stuffing box, in which is inserted a barrel C, bored for the
reception of the ram D, and turned to fit the circumference of the stuffing box
space B.
The ram D may be solid or hollow, reciprocating in the pump A and barrel C,
and in order to prevent the liquid escaping to any great extent from the pump,
annular grooves are cut in the ram D. in each of which is sprung a metallic ring E.
which when inserted in the barrel C. expand against the interior of same, thereby
retaining the liquid within the pump. without the use of a stuffing box, packed
with hemp or cotton, the usual manner, thus dispensing with the time required for
packing the stuffing box and the necessary attention for keeping the gland tight,
to prevent the escape of the liquid.
In order to keep the exterior of pump and surroundings dry, we bore a hole F.
near the top of the additional barrel C. and attach a pipe thereto, by which any
liquid escaping past the rings E. by the ram travelling in the barrel C is conveyed
away.

page_text: Having now particularly described and ascertained the nature of our inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
:-
The combination of a boiler or ram pump barrel A with an additional barrel C.
and ram D. the latter having a number of annular grooves for the reception of
metallic rings E all arranged substantially in the manner and for the purpose as
hereinbefore set forth.
