various purposes.
I form two hollow cylinders by preference of onc casting, one cylinder
being short and of large diameter, horein-after called the large cylinder,
and the other cylinder being longer and of small diameter, hercin-after
called the small cylinder. The latter opens into the lower part of the
former, making an angle of about forty-five degroos therewith. A piston
in the small cylinder is fitted to the lower end of a screwed piston rod
having a handle at its top, which said screwed piston rod works in a
screw box at the top of the cylinder. The large cylinder is also furnished
with a piston. The two cylinders being filled with water, oil, or other
liquid or semi-liquid substanco, constitute a small hydraulic press, tho
depression of the piston in the small cylinder by the turning of its
screwed piston rod raising the piston in the large cylinder with great
force.
The combined cylinders described aro supported in a recess or socket
in a bed plate, to one end of which an arm or lever is jointed, the said
arm or lever having a dome or cavity in it, which is occupied by the
large cylinder and its ram or piston. The small cylinder passes through
a slot in the side of the dome. When the piston of the small cylinder
is at its highest position the piston in the large cylinder is at its lowest
position, and the lever lics upon and parallel with the bed plate. By
placing the bed plate and end of the lever under the rail or other body
to be lifted, and depressing the piston of the small cylinder by its
screwed piston rod the end of the lever and the rail or other body resting
upon it is lifted with great force to the required position.
By reversing tho motion of the screwed piston rod the lever is allowed
to descond to its normal or required position.

O Office within six calendar months next and immediately after the date
of the said Letters Patent.
NOW KNOW YE, that the said Joseph Tangyc, do hereby declare
the nature of the said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement thereof, that is to say :-
My Invention consists of the construction and combination or arrange-
ment of parts herein-after described of machinery or apparatus for
raising or lifting the permanent way of railways, and for lifting heavy
bodies for various purposes.
I form two hollow cylinders by preference of one casting, one cylinder
being short and of large diameter, herein-after called the large cylinder,
and the other cylinder being longer and of small diameter, herein-after
called the small cylinder. The latter opens into the lower part of
the former, making an angle of about 45 degrees therewith. A piston
in the small cylinder is fitted to the lower end of a screwed piston
rod having a handle at its top, which said screwed piston rod works
in a screw box at the top of the cylinder. The large cylinder is

page_text: •
also furnished with a piston. The two cylinders being filled with
water, oil, or other liquid or semi-liquid substance constitute a small
hydraulic press, the depression of the piston in the small cylinder by
the turning of its screwed piston rod raising the piston in the large
cylinder with great force.
The combined cylinders described are supported in a recess or socket
in and are jointed to a bed plate, to one end of which an arm or lover is
jointed, tho said arm or lever having a dome or cavity in it which is
occupied by the large cylinder and its ram or piston. The small cylinder
passes through a slot in the side of the dome. When the piston of the 1
small cylinder is at its highest position the piston in the large cylinder is
at its lowest position, and the lever lies upon and parallel with the bed
plate. By placing the bed plate and end of the lever under the rail or
other body to be lifted, and depressing the piston of the small cylinder by
its screwed piston rod, the end of the lever and the rail or other body 1
resting upon it is lifted with great force to the required position.
By reversing the motion of the screwed piston rod the lever is allowed
to descend to its normal or required position.
Having explained the nature of my Invention I will proceed to
describe with reference to the accompanying Drawing the manner in
which the same may be performed.
Figure 1 represents in side elevation, Figure 2 in longitudinal vertical
section, Figure 3 in plan, and Figure 4 in end clevation (partly in cross
section) a machine or apparatus for raising or lifting the permanent way
of railways and for lifting heavy bodies generally, the said machine or
apparatus being constructed according to my Invention. The same
letters of referenco indicate the same parts in the several Figures
of the Drawing.
a, b, are the combined cylinders of the machine constituting with
their pistons a hydraulic press. The small cylinder & makes an angle of
about 45 degrees with the large cylinder a. The said combined
cylinders a, b, are connected at their base to the bed plate o of the
apparatus by the screw pin or axis d passed through the said base of the
cylinders and the raised sides of the said bed plate. Upon the said
axis & the cylinders a, b, are capable of a limited motion. The lower part
of the cylinder 6 opens by the passage a² into the lower part of the
large cylinder a; e is the piston in the small cylinder 6 provided with

page_text: the usual cupped leather packing; fis the piston rod of the said piston e.
The said piston rod f. is screwed and passes through a screw box g fitted
on the top of the cylinder b. By turning the handle of the piston
rod the pistone may be raised or lowered in the cylinder 6; i is the
ram or piston of the large cylinder a, the said ram having a rounded
head. Its lower end is provided with the usual cupped packing as repre-
sented. The small cylinder and the connecting passage a³ are filled
with water, oil, or other liquid or semi-liquid substance; . is the lifting
arm or lever of the apparatus, having the shape represented and jointed
> by the pin to the heel c² of the bed plate c. The said arm or lever c is
dome shaped, the large cylinder a and its ram or piston occupying the
central cavity in the said dome-shaped arm or lever. The small
cylinder 6 passes through a slot c³ in the side of the dome k. A saddic
piece or frame m on the bed.plate c acts as a stop to the arm or lever k.
The said saddle piece m also constitutes a handle by which the
machine or apparatus may be carried about. When the parts are in their
normal position, as represented in the Drawing, the end ³ of the arm or
lever-k rests on the bed-plate c, the ram or piston i of the large cylinder a
being at its lowest position and the piston.e of the small cylinder 6 being
O at its highest position. When the several parts are in the positions
represented the machine or apparatus is ready for use for lifting the
permanent way of railways and for other lifting purposes.

t
In using the machine or apparatus for raising the permanent way of
railways the wedge-shaped end c' of the bed plate.c. and thọ end "³ of
5 the lifting arm or lever / are placed under the rail or sleeper to be lifted.
By turning the screwed piston rod f in a direction proper to cause it to
advance in the small cylinder b the pistone is depressed in the said
cylinder b, and the liquid or semi-liquid matter in the said cylinder is
forced into the large cylinder a and the ram or piston i raised in the said
O large cylinder a with great force. By the raising of the ram or piston i
the arm or lever / is raised and turns on its centre and the rail or
sleeper resting on the end is lifted with great force to the required
position. As the ram or piston i rises the combined cylinders a, b, turn
on their centre d, the small cylinder 6 moving in the slot c³ and
5 approaching a horizontal position, and the large cylinder a taking an
inclined position.

may be withdrawn from under the rail or sleeper. The machine or
apparatus is used in a like manner for lifting other heavy bodies.
Having now described the nature of my Invention and the manner
in which the same is to be performed, I wish it to be understood that I
do not limit myself to the precise details herein described and illus-
trated, as the same may be varied without departing from the nature of
my Invention; but I claim as my Invention the improvements in
machinery or apparatus for raising or lifting the permanent way of
railways, and for lifting heavy bodies for various purposes, hercin-before ]
described and illustrated in the accompanying Drawing, that is to say,
the combination of the hollow cylinders a, b, and their rams or pistons,
constituting a hydraulic press, with the lifting arm or lever k, k³, and
bed plate c, c³, c³, c², the several parts of the machinery or apparatus
being constructed, arranged, and worked substantially as described and 1
illustrated.
In witness whereof, I, the said Joseph Tangye, have hereunto
set my hand and seal, this Fourth day of September, in the
year of our Lord One thousand eight hundred and seventy-
four.
