I, WILLIAM HENRY GITTINS of 46 Belmont Road Liverpool in the County of
Lancaster Baker do hereby declare the nature of my said invention for IMPROVE-
MENTS IN PORTABLE CRANES FOR LOADING AND UNLOADING WAGGONS AND OTHER
KINDRED PURPOSES to be as follows:-
This invention has for its object a crane that will be always ready to lift or
lower, instead of after each lowering having to be raised again before lowering.
The invention consists: 1st. in forming the crane with a double jib like a scale
beam on the top of a column, and passing a chain or chains (or ropes) from each
end round one or more pulleys in such manner that exactly as rope or chain is
paid out at one end, it is drawn in at the other, consequently by turning the winch
handles in either direction, either end of the jib is raised, or lowered and anything
suspended to it is raised or lowered too. 2nd. The winch is also arranged with
clutch so that it can be used by means of bevel gear and vertical spindle to rotate.
the crane on its axis on the ballasted trolly to which it is pivotted in any usual
manner, such as by means of a fixed standard in the rotary one. 3rd. In place of
the jib rising and falling it can be locked in place by locking pins, either in a hori-
zontal or oblique position and used with pulleys at its ends in the usual manner.
If the jib be horizontal the two chains or two ends of the chain being paid out and
wound in from each jib end alternately, the same result occurs as when the jib see-
saws, but the same height of lift cannot be secured. 4th. The upright or column
of the crane can be telescopic, and raised and lowered with rack and pinion or
other mechanical appliance.

I, WILLIAM HENRY GITTINS of 46 Belmont Road, Liverpool.in the County of
Lancaster, Baker, do hereby declare the nature of 'this invention and in what
manner the same is to be performed, to be be particularly described and
ascertained in and by the following statement:-
This invention is best described by aid of the accompanying drawings in which
Figure 1 is an end view, and
Figure 2 a side view of a crane constructed with a double, jib A A like a scale
beam on the top of a column B and having a chain or chains' CC (or ropes) from
each end round one or more pulleys D D in such manner that exactly as rope or
chain is paid out at one end, it is drawn in at the other, consequently by turning
the winch handles E in either direction, either end of the jib is raised or lowered,
and anything suspended to it is raised or lowered too.
The jib A is constructed so as to turn freely in a vertical arc upon journals at F
as shown. It is supplied with pulleys G and H G H for the chains C also with
hooks I and if desired with additional lengthening piece J for use when the
length of the jib is required to be increased. K are stop holes for holding tho jib
rigid if desired by pins. L telescopic end of column armed with rack M and
pinion apparatus N for adjusting the height of crane before lifting. The rack and
pinion can be locked by ratchet or any other convenient mechanism. 0; 0, are
multiplying gear as in an ordinary winch, D D barrels for ropes CC. P barrel
fixed to same for brake strap, Q platform on which the crane can rotate hori-
zontally in the well known manner being supported therein on friction rollers or
ball bearings and supplied with circular rack and pinion ratchet gear or other well
known mechanism for turning the crane round horizontally. R is a handle for
drawing the crane about. By lowering it the workman presses the other end
against a stout curved horizontal bar S, and thus presses down on the shaft T and
wheel U and raises the main front wheels X off the floor. The shaft T slides in
vertical slide bearings, and has the runner U running in bearings in its forked end;
V eyelets to which the ends of the chains C (lengthened out beyond what is shown
in the drawing) are secured when raising, and lowering by the movement of the
jib. X X front wheels, YY hind wheels, Z platform, which can be made as a
tank, and filled with ballast.
The mode of action is as follows:-
If the crane is to be used with a stationary jib as set forth in the drawing, the
pins K K are inserted by winding on handle E in alternate directions, the
chains C and C¹ are alternately raised or lowered with their weights. If then C is
raised and the weight deposited on the cart by swinging round the crane, C¹ is
in lowered position ready to be attached to a fresh article and by raising C¹ C
is lowered, and so on. If on the other hand it be intended to use the raising and
lowering of the jib, to raise and lower the goods the chains C C¹ are made the right
length to hook onto eyes V V by winding on the winch, then the jibs A A' are
alternately raised and lowered, and the goods are held and raised and lowered with

page_text: it by attachments to hooks I I' or J as the case may be, further a third method of
use can be employed. The hook on I¹ can be attached to V₁ by a short chain so,
that the jib stands at a steep angle, a pulley is then attached to J, and the chain C
lengthened and led over the same and used as an ordinary crane chain.
If the crane has to be removed to another part of the floor the handle R is
depressed, wheels X raised from the ground thereby, and the crane becomes
tricycular on wheels U, Y, and Y, and can be pulled about and guided in any
direction by varying the angle at which the wheel U stands.
I have herein described the best form known to me of carrying out my invention,
but it can be modified in detail without altering the principle involved.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is
1st. The portable cranes for loading and unloading waggons and for other
kindred purposes having double jibs arranged to oscillate in their centres and to
work, substantially as described.
2nd. The arrangement for actuating portable cranes which consists in a winch
with two chains or ropes or two ends of the same chain or rope each led up from
the winch barrel to a separate jib head or end and so wound that as one is paid
out, the other is wound in, substantially as described.
3rd. A double jib crane so arranged that it can rise and lower on opposite sides
alternately, by the movement of the double jib or by the movement of the double
chain on the respective stationary ends of the double jib.
4th. A double jib crane formed with telescopic column, substantially as
described.
