PROVISIONAL SPECIFICATION.
Improvements in Revolving Lamps used for Illumination and
Advertisement and in Apparatus therefor.
I JOHN HORROCKS of 25, Saunder's Street Southport in the County of Lancaster
Engineer, do hereby declare the nature of this invention to be as follows:-
My invention is applicable to lamps used for illumination & advertisement as described
in my former invention for which Letters Patent were granted to me No. 5043 of the
year 1889.
In the above Specification the lamp pillar was described as being continued upwards
within the lamp body which was caused to rotate around it. My present improvemont
is to attach a vertical stem to the lamp body or to its frame which stem lies within the
lamp pillar & does not project higher than the lower part of the frame of or carrying
the lamp body to which it is firmly attached. The said frame rests upon the top of
the pillar & rotates thereon the friction being preferably reduced by ball or roller
bearings. The stem is hollow & the gas supply pipe passes through it. At or near
its lower end the stem is carried in suitable bearings & is caused to revolve by a motor
& suitable mechanism. The motor may be of any of the kinds mentioned in my
previous Specification or it may be an electric motor. When the electric light
is used for illumination the wires are passed through the hollow stem in place of the
gas pipe.
In a modification of my invention the weight of the lamp body & stem is taken at
the foot of the stem instead of at the top of the pillar where the stem is simply guided
in a suitable journal. In this case an anti-friction footstep may be used or ball or
roller bearings.
When lamps are constructed in accordance with my present invention 1 prefer to
use a rotary hydraulic, electric, or other motor.

Improvements in Revolving Lamps used for Illumination and
Advertisement and in Apparatus therefor.
I JOHN HORROCKS of 25, Saunder's Street, Southport, in the County of Lancaster, .
Engineer, 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
--
My invention is applicable to lamps used for illumination and advertisement, as
described in the Specification of my former invention for which Letters Patent No. 5043
of the year 1889 were granted to me.
In the above Specification the lamp pillar was described as being continued upwards
within the lamp body which was caused to rotate around it. My present improvement
is to attach a vertical stem to the lamp body or to its frame, which stem lies within the
lamp pillar and does not project higher than the lower part of the frame of or carrying
the lamp body to which it is firmly attached.
The accompanying drawing illustrates my presont invention.
A is the lamp body which may be in any of the forms illustrated in the drawings
a is the advertisemsat
accompanying my former Specification before referred to.
space. There is no pillar projecting within the body, but only the gas pipe b or it may
be an electric conductor. The body A is attached firmly to the boss B by the brackets ().

page_text: The boss B is screwed, riveited, brazed, or otherwise rigidly attached to the tube or
stem D which is continued downwards within the pillar E, being free to rotate and
is guided by a suitable journal F at or near its lower end.
A set of ball or roller bearings d are inserted between the boss B and the top of
pillar E or of a suitable cap e fitted thereon. By this arrangement the weight of the
lamp body is taken by these bearings at the top of the pillar, and the stem is merely
kept in position by the guide bracket F. But in some cases 1 place the antifriction
bearings between a collar or boss formed on or attached to the stem D near its lower
end and the upper part of the bracket F. In this arrangement the weight of the body
is taken at this lower point and the cape at the top of pillar is made to serve as a
lateral guide merely.
The bovil wheel G is attached to the stem D and is driven by the motor H through
the train of gearing I to reduce the speed to the slow motion required for the lamp
body. In the drawing a rotary water motor is shewn but I may use un electric or
other motor.
The gas pipe or electric conductor passes upwards within the stem D being kept
in position at its npper ond by the ferrule f
The base E of the pillar is formed with a suitable door, and it will be observed that
all the driving niechanism is below and in a readily accessible position.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
-
I. The vertical revolving stem within the lamp pillar substantially as hereinbefore
described.
II. The hollow vertical revolving stem within the lamp pillar substantially as
herein before described and illustrated in the accompanying drawings.
III. The antifriction bearings placed at the upper part of the stem; the-lower-part
being guided laterally, substantially as hereinbefore described and illustrated in the
accompanying drawings.
IV. The antifriction bearings placed at the lower part of the stem, the upper part
being guided laterally, substantially as berein before described.
V. The rotary motor placed within the base of the pillar, substantially as hereinbefore
described and illustrated in the accompanying drawings.
VI. The train of gearing to reduce the speed placed within the base of the pillar,
substantially as hereinbefore described and illustrated in the accompanying drawings.
Dated this 9th day of December 1890.
