Improvements in Apparatus for Raising, Lowering, and Conveying
or Transporting Loads.
We, JOSEPII TEMPERLEY, and JOHN RIDLEY TEMPERLEY, both of The Temperley
Transporter Company, 72 Bishopsgate Street Within, in the City of London,
Engineers, 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 relates to apparatus for raising, lowering and conveying or trans-
porting loads, and more particularly to apparatus of that kind or class in which a
load-carriage or traveller is arranged to be moved to and fro along an overhead
track, and is provided with automatic mechanism for fastening the traveller to
the track while the load is being raised or while it is being lowered, and for locking
the load-sustaining devices when the load is raised, so that the traveller can be
moved along the track in either direction without lowering the load.
Our said invention has for its object to so construct such apparatus that the
load, after being raised, can be swung or slewed around through a complete circle
or any portion thereof, and can also be moved along the overhead track either
towards or away from the centre of the said circle as may be required. We thus
provide for raising a load at any point within a circular area of predetermined
radius, then locking the load-sustaining mechanism and moving the traveller along
the track in one or the other direction, and then fastening the traveller to the
track, unlocking the load-sustaining mechanism and lowering the load. The load,
after being raised at one point in such area, can therefore be transported to and
lowered at any other desired point within the said area.
For this purpose we attach a horizontal or inclined overhead track in any
suitable manner to a vertical rotatory pole or mast or equivalent support, and
mount upon the said track a suitable load-carriage or traveller provided with
automatic mechanism of the kind above referred to; and we connect the lifting,
hauling or other rope or ropes of the said traveller with one or more winches or
other suitable machines, so that the load can be raised or lowered and the traveller
moved along the said track in one or the other direction at will, the hauling or
hoisting machine or machines being either supported upon a platform which
revolves with the central mast or pivot, or being fixed in any convenient position,
in which case the said rope or ropes must pass down through the said revolving
mast or pivot.
According to one method, we mount the revolving pole or mast in or upon a
suitable step or bearing at its lower end and attach suitable stays to its upper
end in such a manner that it can be turned freely about its vertical axis. We
attach a beam or girder or other overhead track, in any convenient manner, to
this pole or mast at a suitable height, and we mount upon the said track a load-
carriage or traveller provided with single or multiple purchase tackle for raising
and lowering the load, and with automatic mechanism of the kind above referred
to, and having suitable wheels or rollers whereby it runs upon the said track.
We pass the lifting or other rope or ropes over suitable pulleys and connect them

page_text: with one or more winches or hoisting engines which are secured to and turn with
the said pole or mast, so that the load can be raised or lowered in any position
of the said pole or mast and overhead track. In some instances we utilize the
lifting rope for hauling the traveller along the track as well as for raising and
lowering the load. In other instances we provide a separate rope and a separate
winch or the like for hauling the said traveller along the track.
We sometimes employ, in place of the said pole or mast, a revolving platform,
carriage or tower loaded so as to counterbalance the weight of the track and of the
traveller and its load.
In the accompanying drawings we have shown how our said invention may be
conveniently and advantageously carried into practice.
Figure 1 is a side elevation showing one form of our improved apparatus, in
which we employ a revolving mast supported by stays, and
Figure 2 is a side elevation showing another form or modification of our said
apparatus, wherein we employ a revolving tower weighted to counterbalance the
load.
Like letters indicate corresponding parts in these two figures.
Referring to Figure 1, a is a revoluble or rotatory pole or mast mounted in a
suitable step or bearing b at its lower end, and provided at its upper end with a
loosely-fitting ring or annular piece c to which are attached stays & for supporting
the said pole or mast in a vertical position, in such a manner as to permit of its
being freely rotated.
The stays d are shown attached to posts e fixed in the ground and further
supported by stays f securely anchored in the ground; the said stays d may,
however, be attached to other suitable supports. They are provided with the
usual tension-regulating appliances. The pole or masta is stiffened by means of
tension-ropes or rods g and a strut h, which strut is made with a ring or hoop
that encircles the said pole or mast.
end
jis the overhead track which consists, as shown, of a light beam or girder, and
which is pivotally connected to the pole or mast a at a suitable height above the
ground, preferably directly opposite the strut h, as at j. The overhead track j
is also supported by means of tension-ropes or slings k attached at their
to the pole or mast «.
upper
7 is the load-carriage or traveller which is provided with
wheels or rollers running upon the track. The lifting and hauling rope m is
passed around a pulley at the outer extremity of the track j, and around another
pulley attached to the pole or mast a at or near the inner end of the said track,
and is connected with a winding or hoisting machine q supported upon a plat-
form which is secured to and revolves with the said pole or mast. The said
winding or hoisting machine may be constructed to be worked by hand or to be
driven by steam, hydraulic or other power as may be desired. If a stationary
hoisting engine is to be used, the rope m will require to pass down through the
pole or mast a and bearing & before being conducted to the hoisting engine.
We employ in our improved apparatus either a single-purchase or a double-
purchase traveller provided with automatic mechanism controlled by the lifting
or hauling rope, whereby, when the load is raised, the Joad-sustaining mechanism
will be locked so that the traveller can be moved along the track in either direction
without lowering the load, and, when the traveller has arrived at the point where
the load is to be lowered, the said load sustaining mechanism can be unlocked and
the traveller will at the same time be secured in position upon the track. For
example, we can use apparatus such as that described in the specification of former
Letters Patent dated 21st. November, 1892, No. 21,170.
In place of the aforesaid revolving pole or mast, we sometimes provide a plat-
form, carriage or tower traversing on one or more circular rails or swivelling upon
a suitable pivot and loaded with the winding or hoisting machine or in any other
convenient manner so as to counterbalance the weight of the track and of the
traveller and its load.
In Figure 2 we have shown an arrangement of this kind in which a tower a is

page_text: built in any convenient form, for example of lattice-girder work as shown, upon a
platform a supported by rollers or wheels a running upon a circular rail or
tracks so that it can revolve about its vertical axis upon a central pivot b.
On that side of the tower a opposite to the overhead beam or track j, the
platform al is extended as at r to form a support for the hoisting mechanism q
which serves also to counterbalance the weight of the track j and the traveller
and its load.
By arranging the pulley in a position vertically above the central pivot b
and providing suitable idle-pulleys or guide-pulleys, the construction of the
apparatus may be modified so that the hauling rope m can be operated by a
stationary engine. In such case the extension of the platform a¹ would be
loaded in any convenient manner.
It is obvious that chains may be substituted for the lifting or hauling ropes
above referred to, and also that the construction of our apparatus may be some-
what further modified without departing from the nature of our said invention.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:-
1. An apparatus of the kind or class herein before referred to, in which the
traveller is provided with automatic mechanism for the purposes above specified,
and which is constructed in such a manner that a load can thereby be raised at
any point within a circular area of predetermined radius and can be conveyed or
transported to and lowered at any other desired point within such area.
2. The combination of a central revolving support, an overhead track attached
thereto and extending therefrom, and a load-carriage or traveller provided with
automatic mechanism for the purposes above specified, and worked by means of
one or more suitable winding or hoisting machines, substantially as, and for the
purpose, herein before described.
3. The improved apparatus constructed, arranged and operating substantially
as hereinbefore described with reference to the accompanying drawing and for the
purposes specified.
