A NEW OR IMPROVED PORTABLE HYDRAULIC TEST PUMP to be as follows
Year: 1884

page_text: PROVISIONAL SPECIFICATION.
I JOHN JAMES ROYLE of 27 & 29 King Street West, Manchester in the County
of Lancaster Mechanical Engineer do hereby declare the nature of my Invention
for "A NEW OR IMPROVED PORTABLE HYDRAULIC TEST PUMP to be as follows :—
"
This invention has for its object the construction of a portable direct acting
Hydraulic test pump and consists of a ram of small diameter sliding loosely within
an outer tube of larger diameter At the lower end of this outer tube is a foot
valve and strainer and at the upper end an annular valve box which also forms a.
portion of the gland through which the ram passes and is made tight by a
cupped" leather. This valve-box is conveniently formed to receive (1) a union
and tail piece for delivering the fluid under pressure (2) a check valve for
preventing the return of the fluid (3) a pressure gauge for indicating the pressure
and (4) a relief valve for discharging the fluid when the pressure is no longer
required the whole forming a very compact and comparatively light and portable
arrangement.
"
In using the pump I provide a "stirrup' or foot support affixed to the pump
barrel at suitable angle to support the pump when placed in a bracket or other
receptacle. The foot of the operator is placed in the stirrup and the pump operator
by working up and down the ram of which is provided with a suitable handle for
the purpose. By making the ram of small diameter and a long stroke and so
disposing it that the whole weight of the operator can be brought to bear directly
over it I obtain a very powerful and simple pump free from levers and complicated
parts, and very handy and portable.
In order to obtain additional discharge from the pump as for filling up large
apparatus previous to "proving" I arrange an additional bucket and valve at the
end of the ram capable of being disconnected when the pump is to be used for
proving only.
When desirable the stirrup before mentioned may be dispensed with and the
pump fixed permanently in a suitable tank.

I JOHN JAMES ROYLE of 27 and 29 King Street West, Manchester in tho
County of Lancaster Mechanical Engineer, do hereby declare the nature of my
invention for "A NEW OR IMPROVED PORTABLE HYDRAULIC TEST PUMP," and in
what manner the same is to be performed to be particularly described and
ascortained in and by the following statement :—
In the accompanying drawing Fig 1 represents a side exterior view and Fig 2
a side sectional view of an hydraulic test pump embracing my improvements and
Fig 3 is a plan half in section and upon an enlarged scale of the same pump
shewing the construction of the improved annular valve box. This invention has
for its object the construction of a portable direct acting hydraulic tost pump and
consists of a ram a of small diameter sliding loosely within an outer tube 6 of
largor diameter as illustrated.
At the lower end of this outer tubo b is a foot valve c and strainer d and at the
upper end an annular valve box e which also forms a portion of the gland f
through which the ram passes and which is made tight by a "cupped" leather g.
This annular valve box is conveniently formed to receive (1) a union h and tail
piece i for dilivering the fluid under pressure; (2) a check valve ; for preventing
the return of the fluid; (3) a pressure gauge k for indicating the pressure and (4) a
relief valve for discharging the fluid when the pressure is no longer requirod.-
the whole forming a very compact and comparatively light and portable
arrangement.
In using the pump I provide a "stirrup" or foot support m affixed to the pump
barrel and at a suitable angle to support the pump when placed in a bucket or
other receptacle (shewn dotted in Fig 1.
The foot of the operator is placed in this stirrup m and the pump is operated
by taking hold of the handle n and so working up and down the ram until the
desired pressure is obtained as indicated by the pressure gauge. By thus making
the ram of small diameter and of a long stroke and so disposing it as aforesaid
that the whole weight of the operator can be brought to bear directly over it
I obtain a very powerful and simple pump free from lovers and complicated parts
and very handy and portable in use.
In order to obtain additional discharge from the pump as for filling up largo
apparatus previous to proving I arrange an additional bucket and valve to bo
screwed on or otherwise secured upon the end of the ram and thus capable of being
disconnected therefrom when the pump is to be used for proving only.
When desirable the stirrup before mentioned may be dispensed with and the
pump fixed permanently in a suitable tank,

page_text: Having thus particularly described and ascertained the nature of my invention
and in what manner the same is to be performed I declare that what I claim as
my invention and desire to secure by Letters Patent is
The improved construction and arrangement of hydraulic test pump with an
annular valve box through which passes the direct acting ram of small diameter
and which also forms the outlet for the flaid under pressure the same being fitted
with a check valve, relief valve, and pressure gauge substantially as and for the
purposes herein before described.
