IMPROVEMENTS IN APPARATUS FOR GIVING MOTION TO
Year: 1884

page_text: I, THOMAS HERON, of 4 Pump Street, London Road, Manchester, in the County
of Lancaster, Gas Burner and Lantern Manufacturer do hereby declare the nature
of my said invention for "IMPROVEMENTS IN APPARATUS FOR GIVING MOTION TO
" to be as follows:-
ADVERTISING SCREENS AND SIMILAR LIGHT ARTICLES
This invention has for its object the construction of apparatus to be worked by
hot air, for the purpose of giving motion to general advertising screens, and other
similar light things which it is desirable to put in action.
The invention consists of a circular sheet of tin plate or other suitable metal
having a number of curved radial cuts from near the centre to the periphery. Each
of the pieces cut is also twisted so that the whole forms something like a many
bladed screw propellor, or fan, having a circumferential rim attached. Extending
from the rim downwards there is a light frame, round which a screen of canvas or
other thin material is stretched, and upon the outer side of this screen advertise-
ments, announcements, pictures, or other matter may be displayed for exhibition.
To the general centre of the vanes or curved pieces of metal before described, a
spindle is fastened. The toe of the spindle works in a step fixed to a suitable base
plate, and the spindle is upheld in a vertical position by supports, which while
keeping it upright also admits of its revolving freely-To the lower part of the
spindle, there may be fashioned a crank, or it may have attached to it an eccentric
or toothed wheel.
To use the apparatus it is necessary to place one or more gas flames, a lighted
lamp, or some other means of producing heat beneath the vanes, when the ascending
current of hot air in escaping from the openings between the vanes will cause the
whole of the inovable parts to revolve and, so display whatever is attached to the
screen. By connecting to the crank an arm, to the eccentric a rod and strap, or by
gearing to the toothed wheel, additional rotary, reciprocating or other motion may
be imparted to machinery requiring but small power to drive it.
One of the uses to which the foregoing arrangement may be applied is the
exhibition of the advantages attending the use of my Patent Duplex Gas Burner,
by causing two ordinary burners to approach and recede from each other, and thus
demonstrate the increased quantity of light to be obtained from two burners when

page_text: appropriately connected. For this purpose there is attached to the spindle an
eccentric strap and rod the latter being fixed to a gas supply pipe, having a gas
burner, and which works backwards and forwards in a cylinder to which gas is
supplied. Upon motion being imparted to the spindle the movable burner is
caused to advance to, and recede from, a fixed burner, with the result as before
described.

I THOMAS HERON of 4 Pump Street, London Road, Manchester in the county of
Lancaster Gas Burner and Lantern Manufacturer do hereby declare the nature of
my said invention for IMPROVEMENTS IN APPARATUS FOR GIVING MOTION TO
ADVERTISING SCREENS AND SIMILAR LIGHT ARTICLES" and in what manner the
same is to be performed to be particularly described and ascertained in and by the
following statement:-
-
This invention has for its object the construction of engines or apparatus to be
worked by hot air for the purpose of giving motion to general advertising screens
and other similar light things which it is desirable to put in action.
The invention, which is clearly represented on the annexed drawings, consists of
a circular sheet of tin plate or other suitable metal A having a number of curved
radial cuts from near the centre to the periphery. Each of the pieces cut is also
twisted so that the whole forms something like a many bladed screw propeller or
fan, having a circumferential rim B attached. Extending from the rim B down-
wards there is a light frame round which a screen of canvas C or other thin
material is stretched and upon the outer side of this screen advertisements,
announcements pictures, or other matter may be displayed for exhibition.
To the general centre of the vanes or curved pieces of metal A before described a
spindle D is fastened. The toe E of the spindle D works in a step F fixed to a
suitable base plate and the spindle D is upheld in a vertical position by a support G
which while keeping it upright also admits of its revolving freely. To the lower
part of the spindle there may be fashioned a crank or it may have attached to it an
eccentric or toothed wheel.
To use the apparatus it is necessary to place one or more gas flames, a lighted
lamp or some other means of producing heat beneath the vanes when the ascending
currents of hot air in escaping from the openings between the vanes will cause the
whole of the movable part to revolve and so display whatever is attached to the
screen. By connecting to the crank an arm, to the eccentric a rod and strap, or by
gearing to the toothed wheel additional rotary reciprocating or other motion may
be imparted to machinery requiring but small power to drive it.

page_text: One of the uses to which the foregoing arrangement may be applied, is the
exhibition of the advantages attending the use of my Patent Duplex Gas Burner
by causing two ordinary burners to approach and recede from each other and thus
demonstrate the increased quantity of light to be obtained from two burners when
appropriately connected. For this purpose there is attached to the spindle an
eccentric strap H and rod I, the latter being fixed to a gas supply pipe J having a
Gas burner K and which works backwards and forwards in a cylinder L to which
Gas is supplied. Upon motion being imparted to the spindle D the movable
burner K is caused to advance to and rece le from a fixed burner M with the result
as before described.
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
The improved apparatus for giving motion to advertising screens and similar
light articles as hereinbefore described and as shown in the annexed drawings.
