Improved Travelling Crane or Hoist.
WILLIAM THOMAS ROUNSIVELL, Mechanical Engineer, 123, Union Street,
Borough, London, S.E., do hereby declare the nature of this invention to be as
follows:-
The object of my invention is to provide a means of dealing with the lifting
of goods where head room or space between the goods to be lifted and the ceil-
ing or roof will not permit of the ordinary construction of lifting gear, also to
provide an arrangement whereby the lifting is performed by means of a suitable
winding gear fixed stationery at any available space in building, thus dispensing
with the usual "fly ropes," square shafts, and the like. I accomplish this in
the following manner. At one end of the longitudinal girders on which the
traveller runs is fixed a sheave No. 1, in any position in order to conduct the
lifting rope to the lifting machine. Upon the traveller itself I fix three hori-
zontal sheaves, No. 2 at one side of one end, No. 3 at the other end, and No. 4
at the other side of the first end. On the transverse girders I fix the ordinary
travelling carriage such as is in use in foundry cranes and the like. A wire rope,
chain or the like, is run from the lifting machine over the guide sheave No. 1
along the longitudinal girders, around sheave No. 2 across the traveller passing
on its way over the before mentioned travelling carriage, thence on to No. 3
sheave, back again over No. 4 sheave, and thence continued on to the extreme
end of longitudinal girders where the rope, chain or the like is anchored.

WILLIAM THOMAS ROUNSIVELL, Mechanical Engineer, 123, Union Street,
Borough, London, S.E., do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
The object of my invention is to provide a means of dealing with the lifting
of goods where head room or space between the goods to be lifted and the ceiling
or roof will not permit of the ordinary construction of lifting gear, also to pro-

page_text: vide an arrangement whereby the lifting is performed by means of a suitablo
winding gear fixed stationery at any available space in building, thus dispensing
with the usual "fly ropes," square shafts and the like. Another important
object of my invention is the application of hydraulic power either by the usual
multiplying jiggers or hydraulic motors. The hydraulic machinery being a fix.
ture in any convenient part of building no flexible or jointed pipes are necessary
The manner in which I accomplish this is as follows. At one end of the longi-
tudinal girders or traveller rails at A Fig. 2, I make a fixing or anchorage for
attaching wire rope, chain, or the like. On the traveller itself are fixed hori-
zontally 3 sheaves B, C, D. At extreme end of traveller rails is fixed another
horizontal sheave E, Fig. 2. On the traveller is a carriage such as is used in
the ordinary foundry cranes. This carries 2 sheaves F and G. A pulley block H,
Fig. 1, hangs between them. I reave the rope or chain as follows, starting at A
Fig. 2, along parallel with girders around sheave B, Fig. 2, across to sheave C,
Fig. 2. thence back across traveller, down over sheave G Fig. 1, under pulley
block H, up over sheave F, continuing across traveller around sheave D Fig. 2,
and along to sheave E. Fig. 2, from thence it can be run to the lifting machinery
fixed stationery in any suitable position. It will be seen that when the lifting
mechanism is set in motion the rope or chain I, Fig. 1, will raise pulley block H,
Fig. 1, and at the same time the traveller can be moved along as described here-
after, the load still remaining the same height, the rope or chain running freely
around the sheaves. For cross traversing I use a similar set of sheaves arranged
as follows and as shewn in Fig. 2. The traversing rope or chain starts also at A.
and follows the lifting rope along to sheave J, fixed under B, thence to and
around sheave K, back to sheave L, fixed under sheave D), thence to and
around sheave M, fixed under sheave E, rope or chain thence passes to traversing
machine which can either be some form of winding gear or hydraulic jiggers
as used for slewing hydraulic cranes. In order to give the other motion to the
carriage N, Fig. 1, I arrange a similar set of sheaves on the other side and reave
rope or chain in the same manner and as also shewn in Figure 2, starting the
fixed end at 0, around sheaves P, Q, R, S The ends of rope at T, and U, can be
connected to the machine fixed in any convenient place. It is necessary to form
one system for the cross traversing, that is to say, the traversing mechanism
must be arranged so that, as one side pulls the other must pay out. I accom-
plish this preferably by means of 2 hydraulic jiggers, one made to exhaust as
the other pulls and vice versa. It will be seen from the foregoing that the load
can be raised from any fixed machine; the traveller being in any position in the
building, and that the whole of the traveller after the load is raised can be moved
either longitudinally or transversely without altering the height of load, the
arrangement of sheaves allowing the lifting rope or chain to accomodate itself
by running freely around sheaves. For longitudinal travelling any suitable
mechanism can be employed such as hydraulic motor, winding gear or hydraulic
jigger or the like. In actual practice it may be found necessary to arrange the
sheaves differently in order to meet the variable requirements of buildings and
the like. The pulleys need not be fixed one under the other as at B, J, Fig. 1,
but can be fixed at side or under the traveller, still adhering to the same principle
of running the wire rope, chain or the like. I also apply the same combination
of parts and arrangement of sheaves fixed on overhanging gantries for projecting
out of buildings or over barges or the like, the lifting and traversing mechanism
being fixed stationery on shore or in building.
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:
1. The application and combination of parts as herein and before described
and illustrated.

page_text: 2. The application and combination of parts and arrangement of sheaves as
required for overhanging or projecting gantries.
3. The same manner of running wire rope, chain or the like but with the
horizontal sheave arranged to suit the various requirements.
