Improvements in Night-light Machines.
I, LUCY HOOKER DAY, of The Novelty Steam Works, Hounslow, in the County of
Middlesex, Manufacturer of Candle Moulding Machinery, Administratrix and
Executrix of the late Arthur Wellesley Day, do hereby declare the nature of this
invention to be as follows:—
The invention has for its object improvements in night light machines whereby
accuracy and simplicity of action are obtained, a method of regulating the size of
the night light is secured,.and means are provided for forming the holes for the wicks
entirely through the body of the night lights by mechanical means.
For this purpose, on a shaft passed between the "piston rods" from one end of
the machine to the other, and on each end of which is fixed one of the toothed
wheels ordinarily employed to operate the racks attached to the main". driving
board," are fixed two counterbalanced levers, one at each end thereof, and such
levers are connected together by a cross bar at one side of the machine, by means of
which the main "driving board" may be raised when required, the counterbalance
weights acting to return the "driving board" to its normal position. By these
means the third toothed wheel ordinarily employed, and to which the ordinary
operating lever is attached, is dispensed with, whilst the main driving board
equally raised from end to end thereof.

For the purpose of adjusting the machine to the production of different sizes of
night lights, screwed dependent rods are fixed on each side of the machine framing,
and such rods pass through lugs from the main "driving board"; adjusting nuts are
screwed on such screwed rods, so that by raising or lowering such nuts, the distance
of travel of the main "driving board " may be adjusted to the size of night light it
is desired to produce.
Also, instead of mounting the perforating wires on fixed bars as heretofore, such
wires are mounted on a supplemental "driving board," which is operated by means
of toothed wheels and racks, to which motion is given by means of a lever fixed to
the axle of such toothed wheels. Thus, after the night lights have been moulded,
and the bottoms of the same have been scraped off flush with the face of the trough,
the perforating wires have a slight motion given to them to complete the perforation
of the night light bodies; by these means the completion of the perforation of the
night lights as heretofore by hand labor, is dispensed with.

Improvements in Night-light Machines.
I, LUCY HOOKER DAY, of The Novelty Steam Works, Hounslow, in the County of
Middlesex, Manufacturer of Candle Moulding Machinery, Administratrix and
Executrix of the late Arthur Wellesley Day, do hereby declare the nature of this
invention, and in what manner the saine is to be performed, to be particularly
described and ascertained in and by the following statement :-
The invention has for its object improvements in night light machines, whereby
accuracy and simplicity of action are obtained, a method of regulating the size of
the night light is secured and means are provided for forming the holes for the wicks
entirely through the body of the night lights by mechanical means.

page_text: For this purpose, on a shaft passed between the "piston rods" from one end of
the machine to the other, and on each end of which is fixed one of the toothed wheels
ordinarily employed to operate the racks attached to the main "driving board," are
fixed two counterbalanced levers, one at each end thereof, and such levers are con-
nected together by a cross bar at one side of the machine, by means of which the
main "
driving board" may be raised when required, the counterbalance weights
acting to return the "driving board" to its normal position. By these means the
third toothed wheel ordinarily employed, and to which the ordinary operating lever
is attached, is dispensed with, whilst the main "driving board" is equally raised
from end to end thereof.
For the purpose of adjusting the machine to the production of different sizes of
night lights, screwed dependent rods are fixed on each side of the machine framing,
and such rods pass through lugs from the main "driving hoard adjusting nuts are
screwed on such screwed rods, so that by raising or lowering such nuts, the distance
of travel of the main "driving board" may be adjusted to the size of night light it
is desired to produce.
Also, instead of mounting the perforating wires on fixed bars as heretofore, such
wires are mounted on a supplemental "driving board," which is operated by means
of toothed wheels and racks, to which motion is given by means of a lever fixed to
the axle of such toothed wheels. Thus after the night lights have been moulded and
the bottoms of the same have been scraped off flush with the face of the trough, the
perforating wires have a slight motion given to them to complete the perforation of
the night light bodies by these means the completion of the perforation of the night
lights, as heretofore, by hand labour is dispensed with.
And in order that the said invention may be more clearly understood and readily
carried into effect, I will proceed aided by the accompanying drawings, more fully to
describe the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a side elevation, Figures 2 and 3 are opposite end elevations, and
Figure 4 is a vertical section, of parts of a night light machine constructed
according to the present invention.
a, a, represent the centre lines of the moulds and pistons, a section of one of
which is shown in figure 4. bis the water box, c is the water supply tube, and d is
the discharge pipe. e is the main "driving board," which carries and operates the
pistons in the following manner.
At the lower end of each hollow piston rod f', is fixed a collar f², which rests on
the main driving board" e, and around each piston rod is a spring, which rests
on the said collar. The hollow piston rods f¹ are passed through a weighting board
or plate, which latter rests on the tops of the springs f³. . represent some of
the moulds, each of which is provided as usual with a descending tube g', by which
it is fixed in the bottom of the water box b, and the lower ends of such tubes g¹
serve as guides to the hollow piston rods f¹.
::
According to the present invention, a shaft his passed between the piston rods f!
from one end of the machine to the other, and on each end of said shaft h is fixed
one of the toothed wheels ordinarily employed to operate the racks i attached to
the main driving board e. On each end of such shaft is fixed a counterbalanced
lever, which levers are connected together by a cross bar 3 at one side of the
machine, by means of which the main
driving board " may be raised when
required, the counterbalance weights * acting to return the main "driving board **
to its normal position.
e
The toothed wheels on each end of the machine gear into each other and into
the racks in the ordinary manner, but by the construction of parts above described, the
third toothed wheel commonly employed, and to which the ordinary operating lever
is attached, is dispensed with, whilst the main "driving board" e is equally raised
from end to end thereof.
For the purpose of adjusting the machine to the production of different sizes of

page_text: night lights, instead of separately adjusting each piston rod on the main "driving
board"
as heretofore, screwed dependent rods are fixed, on each side of the
machine framing, to lugs 6 fixed to the bottom of the water box; such rods pass
through lugs fixed to the main "driving board," and on the lower ends thereof
are placed short tubes j', so that by raising or lowering such tubes j¹ and nuts,
the distance of travel of the main "driving board" e, and consequently of the
pistons f, may be adjusted to the size of night light it is desired to produce.
The short tubes are also provided with set screws j³ for extra security, but if
desired said tubes j¹ and screws ³ may be dispensed with, and the nuts alone
employed.
i
Also, instead of mounting the perforating wires on fixed bars as heretofore, such
wires are fixed to tubes ¹ fitting the lower ends of the hollow piston rods ƒ³, and
mounted on a supplemental "driving board" %, which is operated by means of
toothed wheels m¹ fixed on the ends of a shaft or axle m, such toothed wheels taking
into racks m² fixed to the ends of the supplemental "driving board," and being operated
by means of a lever m³ fixed to one end of the axle m. Thus after the night lights
have been moulded, and the bottoms of the same have been scraped flush with the
face of the trough n, the perforating wires have a slight motion given to them
to complete the perforation of the night light bodies; by these means the completion
of the perforation of the night lights, as heretofore, by hand labour is dispensed
with.
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 1
claim is:
1. In night light machines, the peculiar combination and arrangement of parts
for operating the main "driving board," substantially as herein shown and described.
2. In night light machines, the peculiar arrangement of parts for adjusting the
distance of travel of the pistons, substantially as hercin shown and described.
3. The combination with night light machines, of a supplemental "driving board "
for carrying and operating the perforating wires, substantially as herein shown and
described, and for the purpose stated.
