I, WILLIAM HUTCHINSON of Salford in the County of Lancaster Engineer .do
hereby declare the nature of said Invention for IMPROVEMENTS IN DIRECT ACTING
STEAM PUMPS FOR HYDRAULIC PRESSES, AND FOR OTHER PURPOSES to be as
follows:
:―
My Invention relates to pumps for hydraulic packing presses lifts and the like,
or for other purposes, and the object of my Invention is to improve, and simplify
the pumping engine by dispensing with cranks, fly wheels or pulleys.
To effect this the steam cylinder and the barrels in which the two rams work.
are arranged tandem, and I connect the rams one to either side of the piston in the
steam cylinder; the rams pass preferably through cone metal stuffing boxes fitted
both at the mouths of the working barrels, and at the ends of the steam cylinder:
by the use of these cone metal stuffing boxes I am enabled to dispense with
leathers, and employ flax rope or any other packing if preferred.
-
To the piston of the steam cylinder I connect a sliding valve rod, which passes"
through stuffing boxes at each end of the cylinder lids; this rod near each end.
passes through a slot in the lower end of a vertical pivoted lever; four adjustable*
collars are secured to the sliding rod, and as the latter traverses the collars move
the pivoted levers, which are connected by valve rods working in a steam chest to
the valves which control the admission of steam to the main cylinder.
Each working barrel or hydraulic cylinder is provided with inlet and outlet
pipes fitted with ordinary clack valves.
When steam is admitted into the main cylinder and the piston and rams move
in the right hand direction, water is drawn into the left hand working barrel, and
on the return stroke when the piston and rams move in the left hand direction
water is forced from the left hand barrel, and drawn into the right hand barrel,
and this water is forced from the right hand barrel on the reverse or right hand
stroke of the piston.
This pumping engine may be applied to feed hydraulic packing presses, lifts and
the like, or may be used as a pump for raising and forcing liquids.
Dated this First day of January 1881

page_text: I WILLIAM HUTCHINSON, of Salford, in the County of Lancaster, Engineer, do
hereby declare the nature of said Invention for IMPROVEMENTS IN DIRECT-ACTING
STEAM PUMPS FOR HYDRAULIC PRESSES, AND FOR OTHER PURPOSES, and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:―
My Invention relates to. pumps for hydraulic packing presses, lifts and the like,
or for other purposes and the object of my Invention is to improve and simplify
the pumping engine by dispensing with cranks, fly wheels or pulleys.
To effect this the steam cylinder and the barrels in which the two rams work
are arranged tandem, and I connect the rams one to either side of the piston in the
steam cylinder; the rams pass preferably through cone metal stuffing boxes fitted
both at the mouths of the working barrels and at the ends of the steam cylinder ;
by the use of these cone metal stuffing boxes I am enabled to dispense with
leathers and employ flax rope or any other packing if preferred.
To the piston of the steam cylinder I connect a small piston rod which passes
through stuffing boxes at each end of the cylinder lids: this rod near each end
passes through a slot in the lower end of a vertical pivoted lever a shoe formed
adjustable cam is fitted near each end and as the rod traverses it moves the
pivoted levers which are connected by valve rods working in a steam chest to the
valves which control the admission of steam to the main cylinder. I form the
cylinder lids of cylindrical castings the outer ends of which support the pump
barrels.
Each working barrel or hydraulic cylinder is provided with inlet and outlet
pipes titted with ordinary clack valves.
And in order that my Invention may be fully understood and readily carried
into effect I will proceed to describe the accompanying Sheet of Drawings reference
being had to the Figures and letters marked thereon.
Fig. 1 is a longitudinal sectional elevation of my improved direct-acting steam
pump and Fig. 2 an end view of part of the same.
a is the steam cylinder provided with a piston b connected to the rams c and d
which are fitted and work in the barrels e and f respectively: the cone metal
stuffing boxes are marked g. The stuffing boxes are held in their places by bolts
as shown and they bear against soft metal or ordinary packing held in the conical
recesses. The small piston rod h connected to the piston b and fitted with
adjustable shoe formed cams h¹ passes through stuffing boxes g in the cylinder lids
and through a slot in the lower end of each of the levers j pivoted at j and
connected by rods k to the valves which work in the steam chest m and control
the admission of steam to the cylinder a; n is the starting lever.
When steam is admitted into the main cylinder a and the piston band rains c
and d move in the right hand direction water is drawn into the working barrel e
and on the return stroke when the piston b and rams c and d move in the left hand
direction, water is forced from the barrel e and drawn into the barrel and this
water is forced from the barrel f on the reverse or right hand stroke of the piston.
This pumping engine may be applied to feed hydraulic packing presses, lifts and
the like, or may be used as a pump for raising and forcing liquids.

page_text: Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed, I declare that what
I claim is--
1. The arrangement, construction, and combination of parts forming the
improved direct-acting steam pump, substantially as herein shown and described for
the purposes specified.
2. In direct-acting steam pumps for hydraulic presses and for other purposes
the use and application of the cone metal stuffing boxes g as herein set forth.
WILLIAM HUTCHINSON.
