PROVISIONAL SPECIFICATION.
Improvements relating to Revolving Lamps or Lanterns.
WALTER HENRY PRICE of No. 33 Chester Road, Sunderland, in the County of
Durham, Sign Writer do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in revolving lamps or lanterns of the kind
referred to in my previous Patent No. 7920 dated 30th May 1888.
In carrying out my invention the rod on which the lamp revolves works in upper
and lower bearings, the upper bearing being adapted to slide in a socket in such a
manner that as the bearing points of plumbago or other suitable lubricous material of
the revolving rod wear, the upper movable bearing automatically falls so as to
compensate for the said wear, the said movable bearing also allowing for any
expansion which may take place. The bearing ends of the revolving rod preferably
rotate on glass or like material.
By this arrangement I am also enabled to employ heavier lamp or lantern frames
than hitherto and with glass sides.
Another advantage derived from my improvements is that the lamp frame can be
placed in position in its bearings or removed therefrom in a much simpler manner
than hitherto.

COMPLETE SPECIFICATION.
Improvements relating to Revolving Lamps or Lanterns.
WALTER HENRY PRICE of No. 19 Alice Street, Sunderland, in the County of
Durham, Sign Writer 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
:-
This invention relates to improvements in revolving lamps or lanterns of the kind
referred to in my previous patent No. 7920 dated 30th May 1888.
In carrying out my invention the rod on which the lamp revolves works in upper
and lower bearings the upper bearing consisting of a socket or tube so that as the
lower bearing point of the revolving rod wears the rod falls so as to compensate
for the said wear. By these means provision is also made for any expansion which
may take place.
In order to enable the invention to be fully understood I will proceed to describe
the same by reference to the accompanying drawing in which figures 1, 2 and 3
are vertical sections of revolving lamps constructed according to my improvements.
Referring to figure 1 the lamp frame a having vanes or fans b, is attached to a
rod c, provided at either end with tips of plumbago or other suitable material. The
rod c, is held in position by means of an arm d, attached to the burner bracket
and provided at its upper part with a socket or bearing e, in which is a loose
bearing of glass or other suitable material; the lower part of the rod works in
a socket g, on the burner bracket, provided with a bearing h, of glass or other
suitable material.
The arrangement shewn in figure 2, is the same as that illustrated in figure 1
except that instead of employing a loose bearing such as f, the lower part of the
socket e, is turned inwards so as to leave a small opening i, which forms the

page_text: bearing for the upper part of the rod
or other suitable metal at each end.
" the rod being provided with points of steel
With these arrangements, in order to remove the lamp from the arm it will be
obvious that it is only necessary to raise the frame and move it to one side when
the frame and its supporting rod can be easily and quickly removed.
Figure 3, shews an arrangement of my improved revolving lamp or lantern in
which I dispense with the use of the supporting arm.
In this arrangement the upper part of the frame a, is formed with a recess j. in
which is fixed the rod c, (the lower part being provided with a point of steel or
other suitable metal) working in a sleeve or tube, fixed to the burner bracket.
The rod c, is longer than the sleeve k, so that when placed in position the
upper part of the sleeve reaches nearly to the top of the recess j; the sleeve is
provided at its lower part with a suitable hearing piece, and the upper part is
turned inwards (similarly to the socket e, in figure 2) to form an opening, of
sufficient size for the rod c, to work freely therein.
By my improvements the wear of the rod and the bearings will be found to be
inappreciable and a more regular action of the lamp is obtained in consequence of the
weight of the lamp being taken by the bottom hearing which is kept relatively cool.
Moreover I am enabled to employ heavier lamp or lantern frames than hitherto thus
allowing of using glass sides.
It will be obvious that instead of the rod being provided with a point at the bottom
such point can be formed on the burner bracket and the rod can be made with a
conical recess at the bottom in order to rotate thereon.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what 1
claim is :-
1. A revolving lamp or lantern consisting of a frame mounted on a revolving rod
working loosely in top and bottom sockets or bearings the lower bearing serving to
support the weight of the lamp and the upper bearing serving to hold or steady the
rod substantially as hereinbefore described and illustrated in the several figures of the
accompanying drawing.
2. The manufacture and use of the improved lamps or lanterns hereinbefore
described and illustrated in figures 1, 2 and respectively of the accompanying
drawing.
