Improvements in Revolving Dioramas.
I, HUGH DONALD FITZPATRICK, of 70 Wellington Street, Glasgow,
Registered Patent Agent, do hereby declare the nature of this invention to be
as follows:-
This invention relates to revolving dioramas and it has for its object to enable
the spectator, as each picture passes before him, to regulate the light thrown on
the picture, for the time being in view, to suit his fancy.
In carrying out my invention I use a circular stationary frame having a number
of lenses or eye holes in it and inside this frame I fit a revolving frame carrying
stereoscopic boxes with views. This revolving frame, (or the boxes,) has a circular
grooved rail on its underside which runs on rollers or wheels fitted on a flange
carried by the stationary frame. At the back of the boxes and carried by the
stationary frame is a gas pipe having jets in it to correspond to the number of eye
holes or lenses. These jets can individually be turned up or down by means of a
series of spindles one for each flame passed through the stationary frame and
provided with knobs or handles at the end. Each spindle is capable of operating
the lever or handle of a gas tap situated below each gas jet and controlling the gas
supply thereto. The spindle inaychave nuts and a collar device for actuating the
lever or handle.
The revolving frame may be driven by clockwork or by hand.
Fitted to and above the revolving frame is an indicator on which the names of
the different views are painted or shown, and this indicator, as it revolves, indicates
through openings in the stationary frame the name of each view as it appears in
front of the spectator.
Dated this 28th day of March 1895.

COMPLETE SPECIFICATION.
Improvements in Revolving Dioramas.
1, HUGH DONALD FITZPATRICK, of 70 Wellington Street, Glasgow,
Registered Patent Agent, 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 revolving dioramas and it has for its object to enable
the spectator, as each picture passes before him, to regulate the light thrown on
the picture, for the time being in view, to suit his fancy.
And in order that my said invention may be properly understood I have hereunto
appended an explanatory sheet of drawings, whereon,
Fig. 1 is a vertical section of the diorama.

page_text: Fig. 3 is a plan view.
Fig. 4 is a sectional view to an enlarged scale.
Fig. 5 is a view of the regulating device for the gas jets.
In carrying out my invention, I use a circular stationary frame A having a
number of lenses or eye holes A' in it. This frame is supported on a circular
table B, provided with legs, and which is sufficiently broad to enable the spectator
to rest his arms comfortably on a cushion C thereon. Inside this frame I fit a
revolving frame D supported by means of spokes H from the top of a vertical
shaft F and which carries a number of stereoscopic boxes with views. The boxes
have secured to their undersides a circular grooved rail a which runs on rollers b,
or wheels, fitted on a flange or shelf E carried by the stationary frame. At the
back of the boxes and carried by the stationary frame is a gas pipe B' having
jets L corresponding to the number of stereoscopic views. These jets L can
individually be turned up or down from behind and without interfering with the
rotation of the boxes by means of a series of spindles 2, one for each flame, passed
through the stationary frame A, and provided with knobs or handles 1 at their
outer ends. Each spindle, which is screwed at its inner end 3, is provided with
two nuts 4, 4, between which a ring, connected to the lever handle 5 of the gas tap
of the burner, is caught in such manner that by pulling or pushing the handle i
the gas can be turned up or down so as to illuminate the picture to the degree
required by the spectator.
The shaft F, which is hollow, is fitted on the top of a pillar G and has a
bevel wheel e at its lower end which gears with a wheel f on a short shaft
operated by means of a crank handle or by clockwork mechanism contained in a
box i.
Fitted to and above each stereoscopic box is an indicator c carrying an
exchangeable slide d on which the name of a view is painted or shown, and these
indicators, as they revolve, indicate through openings in the stationary frame A
the names of the different views as they appear in front of the spectator.
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
consider novel and desire to claim is :-
A diorama with its revolving stereoscopic views and its individually controlled
gas jets constructed substantially as hereinbefore described with reference to the
drawings annexed.
Dated this 27th day of December 1895.
