page_text: I JAMES FOYELL LOVELOCK CROSLAND of 67 King Street Manchester in the
County of Lancaster 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 relates to portable hydraulic force pumps such as are employed for
testing the strength of steam boilers and for other analogous purposes and the object
of the invention is to increase the portability of such pumps, and to afford a ready
means of mounting and setting up such pumps for use with facility and despatch and
of dismounting and packing the same for removal and transport, at the same time that
the weight and bulk are considerably reduced.
The invention consists principally in so constructing and arranging the stand or
pedestal upon which the pump is mounted that the latter when dismounted can be
readily packed in the interior thereof so that the said pedestal serves for two purposes,
namely for a frame or base to support the pump when in use, and also as a case for
packing the same for transport; and thus the necessity for a separate stand or frame
and case is obviated and both the bulk and the weight to be carried from place to
place are geatly diminished.
The manner in which my invention is carried into practical effect will be readily
understood on reference to the annexed sheet of drawings and the following explanation
thereof.
Fig. 1. on the drawing is a front elevation representing the hydraulic force pump
mounted on the pedestal ready for action.
Fig. 2 is a side view of the pedestal alone, and Fig. 3. is a front view of the same
with the pump dismounted and packed in the inside thereof ready for transportation,
the door being removed to show the same more clearly.
Fig. 4. is a sectional detached plan view hereinafter referred to.
The pedestal a is shown on the drawing in the form of a truncated pyramid and
made of wood, which form and material I prefer as combining lightness and rigidity
with great portability, but I would here remark that the sides may be vertical if

page_text: preferred and that it may be of an octagonal or other convenient form in ground plan
if thought desirable, and it may also be made of sheet metal panels, with a light frame
of angle iron.
I cast the cylinder of the pump with a base plate c having (by preference) four
lugs as shown by the detached plan view at Fig. 4. by means of which it may be
bolted firmly to the top of the pedestal a (as shown at Fig. 1) by the four bolts and
"butterfly" nuts d when required for use; and to dismount the pump all that is
required is to unscrew these four nuts.
The pump can then be placed inside the pedestal a as shown at Fig. 3. the base
plate of the cylinder sliding beneath the two fixings e and the loose lever or handle f
being removed and supported by the fixing g. The suction and delivery hose are also
removed from the pump and are placed inside the pedestal but these are not shown on
the drawing to avoid confusion of lines.
The holding down bolts being also reversed as shown, the door of the pedestal can
be shut and locked and the whole is then ready for transportion as shown at Fig. 2.
A recess with a movable cover may also be formed as shown at h to carry spare
union joints or other small detached pieces or articles.
Having now particularly described and ascertained the nature and object of my
said invention, and the manner in which the same is to be performed I declare that
what I claim is
The combination with a portable hydraulic force pump of a pedestal so constructed
and fitted that when the pump is dismounted therefrom it may be readily and securely
packed therein for transportation substantially as hereinbefore described and illustrated
by the drawings annexed.
