Complete Accepted, .22nd..Feb., 1887.
I, HENRY LONG, of 12, Armoury Square, Stapleton Road, in the city and county of
Bristol, engineer, do hereby declare the nature of this invention to be as follows :-
This invention consists in an improved direct-acting steam pump in which the
piston rods of the steam cylinder and the pump respectively are attached directly to
opposite ends of an intervening link or frame, and in which the fly wheel, in addition
to acting as a balance for assisting the engine over the dead centres, operates the
slide valve. The eccentric sheave is made in one piece with the crank which is driven
by means of a connecting rod attached at one end thereto, and at the other to the
link or frame aforesaid.
The thrust or stroke of the engine is maintained in the proper plane by a guide rod
fixed to the main frame of the engine and passed through a sleeve secured to or made
in one piece with the link or frame which, as aforesaid, the piston rods of the steam
and pump cylinders are attached. Excepting a space for the passage of the piston
rod, that end of the steam cylinder at which the stuffing box is situated is cast closed
and a steam joint thereat is consequently avoided.

I, HENRY LONG, of 12, Armoury Square, Stapleton Road, in the city and county of
Bristol, engineer, 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 consists in an improved direct-acting steam pump in which the
piston rods of the steam cylinder and the pump respectively are attached directly to

page_text: opposite ends of an intervening link or frame, and in which the fly wheel, in addition
to acting as a balance for assisting the engine over the dead centres assists to operate
the slide valve. The eccentric sheave is made in one piece with the crank which is
driven by means of a connecting rod attached at one end thereto, and at the other to
the link or frame aforesaid. The thrust or stroke of the engine is maintained in the
proper plane by a guide rod fixed to the main frame of the engine and passed through
a sleeve secured to or made in one piece with the link or frame to which, as aforesaid,
the piston-rods of the steam and pump cylinders are attached.
The occurrence of a steam joint at the stuffing-box end of the steam cylinder is
obviated by casting the cylinder closed at that end leaving only an orifice for the
piston-rod.
Referring to the accompanying sheets of illustrative drawings, the figure on sheet 1
represents a front view of a pump constructed in accordance with this invention. The
figure on sheet 2 represents a transverse vertical section, partly in elevation.
The piston-rod a of the steam cylinder and the piston-rod of the pump cylinder d
are connected to the link e. The thrust or stroke of the piston rods a and c is
maintained in the proper plane by means of the guide rod passing through a sleeve
formed on the link e and carried in brackets attached to the frame. By thus
coupling the piston-rods of the steam cylinder and the pump to an intermediate link
such as e, a smooth and even working is obtained and construction is simplified.
The eccentric sheave is formed on or bolted to the disc crank secured to the shaft/
to the outer end of which is fitted the fly-wheel which in addition to assisting the
engine over the dead centres operates the slide valve to the spindle a of which the
eccentric rod » is connected. The crank is connected to the link e by the connecting
rod k¹.
()
The stuffing box end of the steam cylinder is cast closed except that an orifice
for the piston-rod a provided. A steam joint at the said end of the cylinder is thus
obviated.
Having now particularly described and ascertained the nature of this invention,
and in what the same is to be performed, I declare that what I claim is :-
1. In a steam pump wherein the steam and pump cylinders are directly opposed,
coupling the piston rods of the said cylinders to an intermediate link such as e guided
in its motion by means of a guide rod such as; held in brackets such as y, or guided
by equivalent means, substantially as hereinbefore described with reference to the
accompanying sheets of illustrative drawings.
2. In a steam pump, the employment, for imparting motion to the slide valve of the
steam cylinder, of an eccentric such as i formed on or secured to a crank such as k,
and assisted to operate by the momentum of the fly-wheel m whereby, through the
medium of a connecting rod and spindle, the slide valve is reciprocated substantially as
hereinbefore described.
3. The use in a steam pump of a cylinder such as having the stuffing-box end
closed except an orifice for the passage of the piston rod, whereby the necessity of a
steam joint thereat is obviated, as hereinbefore described.
4. The combination of parts constituting the improved steam pump constructed,
arranged and operating substantially as hereinbefore described.
