A communication by WILLIAM BUSCH, of Marktplatz, Hamburg, Germany
I, CARL BUSCH, of 243, Cleveland Street, Birkenhead, in the County of Chester,
Manager, do hereby declare the nature of this invention to be as follows:-
This invention has for its object an arrangement of lifting jack, and is specially
designed for lifting the bodies of tiamcas off then wheels though it may also be
used for other purposes
It consists essentially in a standard formed of two columns or beams a shoit
distance apart, having a firm broad base On this standard is a bracket at a con-
venient height, and ciank On the shaft of this crank is a bevel wheel gearing
into a similar bevel wheel on a vertical shaft. This vertical shaft has a bearing
near the top supported on the standard, and a spui wheel geaning into another
spur wheel on a shaft having ball bearings on the top of the standard This
shaft is screwed to near the bottom, and is supported in a foot-step in the bottom,
80 that it can revolve. On this screwed shatt I place a nut so constructed as to
support one end of a stout beam which is placed under the car when it is required
to be raised There is a similar apparatus at the other end of this beam to sup-
port the opposite end thereof, the length of the beam being equal to at least the
width of the car In some cases however one end of the beam might be sup-
ported on a stationary abutment and the other end only provided with the lifting
jack arrangement The screwed shaft has preferably a solid head in a circular
grooved race in which 'the balls of the ball bearing travel, the bracket attached
to the standard carrying a similar lace for the balls to run on The bottom of
the shaft works in a foot step, which, together with the ball bearings at top,
resist the downward pressure due to the weight of the car body
The mode of action is as follows:-
The beam is placed under the car body, and two standards (if two be used)
adjusted to the beam The crank handles are now 1otated raising the beam and
thus raising the car body off the wheels If desued two apparatus may be
applied to the car body so as to lift both ends off the wheels. The ends of the
beam have preferably a claw arrangement to prevent it accidentally slipping off
the supporting nuts that use and fall by the rotating of the sciew
In thus describing the invention, I wish it to be understood that certain altera-
tions may be made therein without departing from the general idea.

I, CARL BUSCH, of 243, Cleveland Street, Birkenhead, in the County of Chester,
Manager, do hereby declare the nature of this invention and in what mannei
the same is to be performed, to be particularly described and ascertained in and
by the following statement:—
This invention has for its object an arrangement of lifting jack, and is especially
designed for lifting the bodies of tramcars off then wheels though it may also be
used for other purposes.
The invention will be understood from the following, description reference being
had to the accompanying drawings, in which,
Fig 1 is a side elevation;
Fig. 2 a front elevation,
Fig. 3 an enlarged view of part of the apparatus with the gearing and bearings
It consists essentially in a standard formed of two columns or beams A a short
distance apait, having a fim broad base B On this standard is a bracket C at a
convenient height and a crank D On the shaft of this crank 16 a bevel wheel E
gearing into a similar bevel wheel F on a vertical shaft G. This vertical shaft
has a bearing H near the top supported on the standard A, and a spur wheel 1
gearing into another spur wheel Jon a shaft K having ball bearings L on the top
of the standard A. This shaft is screwed to near the bottom, and 18 supported
in a footstep M in the bottom, so that it can revolve On this screwed shaft K
I place a nut L' so constructed as to support one end of a stout beam A which
18 placed under the car when it 18 required to be raised The nut is arranged
between the two columns so that it cannot rotate There is a similar apparatus
at the other end of this beam to support the opposite end thereof, the length of
the beam being equal to at least the width of the cal. In some cases however
one end of the beam might be supported on a stationary abutment and the other
end only provided with the lifting jack arrangement. The screwed shaft K has
Preferably a solid head N with a circular grooved race in which the balls of the
ball bearing travel, the bracket attached to the standard carrying a similar race ()
for the balls to run on The bottom of the shaft works in a foot step, to secure
perfect alignment, the downward pressure due to the weight of the car body
being carried upon the ball bearings at the top
The mode of action is as follows:-
The beam 18 placed under the car body, and two standards (if two be used)
adjusted to the beam. The crank handles are now rotated raising the beam and
thus raising the car body off the wheels. If desired, two apparatus may be
applied to the car body, so as to lift both ends off the wheels
beam have preferably a claw arrangement to prevent it accidentally slipping off
the supporting nuts that rise and fall by the rotating of the screw
The ends of the
In thus describing the invention, I wish it to be understood that certain altera-
tions may be made therein without departing from the general idea
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed as communicated to me by
my foreign correspondent, I declare that what I claim 19-
1. A lifting jack comprising a standard, a vertical screwed shaft with nut
thereon arranged to rise or fall as said shaft 18 rotated, a second shaft geared to
the screwed shaft, and means for rotating said shaft ao as to raise or lower the
nut, in combination with a beam adapted to be passed under the object to be lifted

page_text: and the respective ends supported on the nuts of a pair of lifting jacks or one
end supported on a stationary abutment and the other end on the nut of a lifting
jack substantially as described
2. In lifting jacks, the arrangement of ball bearings on the rotary shaft that
carries the nut in such manner as to allow for rotation and yet resist the downward
pressure due to the weight of the object which is being lifted or supported sub-
stantially as described
3. An arrangement of lifting jack for lifting objects such as tramcars from off
their wheels and other purposes, constructed, arranged and operated substantially
as herein before described with reference to and shown in the drawings annexed.
