We JOHN WILLIAM BUCKLEY of Charles Lane, Sheffield- in the county of York,
Engineer, and ARTHUR THOMAS ALLEN of Paradise Square, Sheffield aforesaid
Engineer do hereby declare the nature of this invention to be as follows:-
Our Invention of improvements in lifting appliances refers more especially to
Apparatus for lifting or raising railway rails, but may be used for other similar
lifting purposes.
In constructing an Apparatus according to my invention, I cast or otherwise
produce a vertical tubular guide, having an extended hollow base fixed upon a strong
baseplate; the front of the tubular part is cut away from the top downward leaving
an opening into the centre opening through which the lifting claw projects.
The lifting Screw rests at its bottom end in a suitable recess, or step, in or upon
the base plate, and the top of the screw is held in position, by an end plate attached
to the said tubular guide, and upon the body of the screw a strong lifting claw is
fitted; the body part or nut being tapped, or cast, with a screwthread corresponding
to that of the screw, and the claw being made to project through the side opening
and thus the combined lifting claw and nut is prevented turning round.
The screw is rotated by means of a wheel secured upon its lower end and enclosed
in the hollow of the base, the said wheel being driven by a pinion the axis of which
projects from the base, and is squared or otherwise prepared to receive a handle.
Instead of the vertical tubular guide we make the base plate with a recess to
receive the wheel and pinion, and support the top of the screw by means of an arm
projecting from a standard.
The nut is made with a flange and two flat sides, and the screw is rotated by a wheel
and pinion as before described.
The lifting foot or claw consists of two bars (or a double lever), the back ends being
secured to the standard by a strong bolt or equivalent means, and the front ends being
secured together in a similar manner-or it may be made in one solid piece. The
flat sides of the nut are held between the double part or sides of the lever and the
lower edges rest upon the flange of the nut. A self adjusting face to counteract the
circular motion of the lever may be used if desirable.

page_text: We JOHN WILLIAM BUCKLEY of Charles Lane, Sheffield, in the County of York,
Engineer, and ARTHUR THOMAS ALLEN of Paradise Square, Sheffield aforesaid,
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 :-
Our invention of improvements in appliances or Apparatus for lifting purposes
refers more particularly to Apparatus for lifting or raising the rails of Railways, but
which may be also used for other similar lifting purposes.
The annexed sheet of drawings illustrates an Apparatus made according to our
said invention, and for the purpose above mentioned representing a side elevation of
such an Apparatus, part of the base being removed to show the interior.
In carrying out our invention, we make a suitable base A to receive and enclose a
wheel B, and pinion C, and to carry a standard D. The said standard D projects
forward over the base A as shown for the purpose of supporting the top end of the
lifting screw E, which is firmly secured to the wheel B, and also the spindle F, of
of the pinion C; both the screw E and the spindle F take a bearing in the
base plate A.
To the vertical portion of the standard D we attach two arms G, one upon each
side, and capable of a vibrating or axial movement upon a strong joint pin H; the
forward ends of the arms are curved to receive the segmental sides of the lifting
cradle I, which is provided with a vertical guide piece J, sliding upon the end of the
standard D.
A strong nut or screwthreaded block K, fits upon the screw E and is provided with
projecting sides upon which the arms G rest, and we prefer to curve the upper side
as shown to reduce any friction at this point. The arms G prevent the nut from
turning round with the screw E, and therefore upon the screw being caused to revolve
by the action of wheels B and C set in motion by a handle applied to the square head
of either E or F, it follows that the nut will either rise or fall upon the screw and
raise or lower the arms G and cradle I, according to the direction in which the handle
is turned.
When a comparatively light weight is to be raised, and the movement is required
to be quick, the lever is applied to the head of the screw E, but where great lifting
power is required the lever is applied to the pinion spindle F, the weight to be lifted
in all case resting on the cradle I, which by reason of its segmental configuration will
accommodate itself to the varying position of the double arm G as it rises or falls.
Although we have shown the wheel and pinion as ordinary outside toothed gearing,
we may if desirable use an internal toothed wheel for the purpose of causing both
the spindle F, and the screw E to turn in the same direction, instead of in opposite
directions, when lifting or when lowering.-

page_text: As a modification of the above described apparatus we may dispense with the
arms G, and form a claw or lifting foot upon the nut K; the screw in this case would
be enclosed in a fixed tubular column provided with an opening through which the
claw or lifting foot would project, and which would allow of the desired vertical
movement.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1-The lifting Apparatus, substantially as hereinbefore described and as illustrated.
2-A lifting apparatus consisting of a base A; a screw E, having a wheel B, in
gear with a pinion C; the said screw having a nut K, upon which one or more arms G
take a bearing, and support a Cradle I, for the purpose specified, and substantially as
described and illustrated.
3-As a lifting apparatus, the modification in which the arm or arms are dispensed
with substantially as hereinbefore described.
