I, JAMES BRUNT of 55 Ward Street Hanley, in the County of Stafford, Engineer,
do hereby declare the nature of this invention to be as follows:-
My invention consists chiefly in improvements in the construction of that class of
pumps known as direct acting steam pumps, but may be applied to other kinds.
In the construction of these pumps two Cylinders are usually employed, one
containing a piston moved by steam or compressed air, and one containing the bucket
or ram which operates on the water or whatever is to be pumped. The piston, and
bucket or ram, as the case may be, are connected together by a rod working through
packing boxes and Glands placed face to face in the covers of each Cylinder.
My invention consists first in the construction of a ram case or chamber, having
an internal packing box in the middle of its length, and also of a gland by which
packing rings of any description may be tightened or adjusted upon and round the
ran, enabling the ram to act or force when moving in either directions.
The Gland is constructed to extend to the outer cover of the ram case, and is
perforated with holes or slots through which any liquid may pass freely as the rain
moves to and fro. Also there are provided in the cover or door of the ram case,
one or more screws working through packing boxes or otherwise by means of which
the Gland may be moved forward to tighten or adjust the packing rings upon
the ram.
The second part of my invention consists in an improved arrangement for directing
the steam or compressed air to either side of the main piston alternately, and for
exhausting the saine.
For this purpose I employ a circular valve fitting in a circular chamber, out of
which. passages or pipes extend to the ends of the main Cylinder. The central part
of this valve having ports or passages so formed and arranged that communication
may be alternately opened and closed, between either side of the piston and the main
supply, and between either side of the piston and the atmosphere.
The ends of this valve serving as pistons, and having rings of metal or brass,

page_text: fitting in grooves, these pistons to be operated upon by pressure of steam or air, the
whole moving to and fro as the pressure against either end is alternately increased or
relaxed.
The valve may be made rigid and in one piece, or of two or more parts fitted
together, as may be found convenient or desirable. It may also be made elastic or
expansive to compensate for wear.
The valve case may be made separate from the main Cylinder and fitted on. The
valve and case or either of them may be made of steel or brass or any suitable metal.
I accumulate pressure against the ends of the valve by connecting the ends of the
case or chamber in which it works, with the main supply, by means of pipes of small
diameter, in which are placed small cocks or valves, each of which may be more or less
open as required.
I exhaust either end of the valve case or chamber alternately, by means of a small
circular sliding valve having motion from the crosshead of the pump or from any
other convenient part.
Another improvement consists in the employment of adjustable guide bars, with
accurately planed surfaces upwards, extending from cylinder to cylinder and the
placing of them on either side of the main rod, so that any liquid dropping from the
rod or lands shall fall between them, and not interfere with lubrication.
Upon these guide bars, by means of a crosshead secured to the main rod, I balance
the main moving parts of the pump, and thus confine the friction arising from the
weight of those parts to an adjustable and easily lubricated surface.

COMPLETE SPECIFICATION.
An Improved Construction of Steam and other Pumps.
I, JAMES BRUNT. of 55 Ward Street Hanley, Staffords, Engineer, do hereby declare
the nature of this invention and in what manner the same is to be performed, to
he particularly described and ascertained in and by the following statement:-

pumps known as "direct acting steam punips," but may be applied to other kinds.
In the construction of these pumps two Cylinders are usually employed, one
containing a piston moved by steam or compressed air, and one containing the bucket
or ram which operates on the liquid to be pumped.
The piston and bucket or ram as the case may be are connected together by a rod
working through packing boxes and glands placed face to face in the covers of each
evlinder.

This invention consists chiefly in improvements in the construction of that class of
pumps known as "direct acting steam punips," but may be applied to other kinds.
In the construction of these pumps two Cylinders are usually employed, one
containing a piston moved by steam or compressed air, and one containing the bucket
or ram which operates on the liquid to be pumped.
The piston and bucket or ram as the case may be are connected together by a rod
working through packing boxes and glands placed face to face in the covers of each
evlinder.
My invention consists first in the construction of a ram case or chamber having an
internal packing box in the middle of it- length and also of a gland by which packing

page_text: ings of any description may be tightened or adjusted upon and around the ram.
nabling the ram to act or force when moving in either direction.
The Gland is constructed to extend to the outer cover of the ram case and is
perforated with holes or slots through which any liquid may pass freely as the ram
moves to and fro.
Also there are provided in the cover or door of the ram case, one or more screws
working through packing boxes or otherwise, by means of which the gland may be
moved forward to tighten or adjust the packing rings upon the ram.
The second part of my invention consists in an improved arrangement for directing
the steam or compressed air to either side of the main piston alternately, and for
exhausting the same.
For this purpose I employ a cylindrical valve fitting in a cylindrical chamber out of
which passages or pipes extend to the ends of the main cylinder.
The central part of this valve having ports or passages so formed and arranged,
that communication may be alternately opened and closed between either side of
the piston, and the main supply, and between either side of the piston and the
atmosphere.
The ends of this valve serve as pistons and have rings of metal or brass, fitting
in grooves. These pistons are to be operated upon by pressure of steam or air, the
whole moving to and fro as the pressure against either end is alternately increased or
relaxed.
This valve may be made rigid and in one piece, or of two or more parts fitted
together, as may be found convenient or desirable.
It may also be made elastic or expansive to compensate for wear.
The valve case may be made separate from the main cylinder and fitted on.
The valve and case or either of them may be made of steel or brass or any suitable
metal.
1 accumulate pressure against the ends of this valve by connecting the ends of the
case or chamber in which it works, with the main supply by means of pipes of small
diameter, in which are placed small cocks or valves, each of which may be more or less
open as required.
I exhaust from the side of the valve case or chamber as shown in Fig. 5, by means
of a small sliding valve, having motion from the crosshead of the pump or from any
other convenient part of the pump.
Another improvement consists in the employment of adjustable guide bars, with
accurately planed surfaces upwards, extending from cylinder to cylinder, and the
placing of them on either side of the main rod so that any liquid dropping from the
rod or glands shall fall between them and not interfere with lubrication.
Upon these guide bars by means of a crosshead secured to the main rod, I balance
the main moving parts of the pump, and thus confine the friction arising from the
weight of those parts to an adjustable and easily lubricated surface.
