This invention relates to a motor engine and steam generator more particularly
adapted for operations requiring a small power, such as for driving sewing machines.
The construction will be readily understood on reference to the accompanying
drawings, Fig. 1 of which shews the motor engine as applied to a sewing machine.
It consists of a small steam engine A with oscillating cylinder supplied with steam
from the generator B of peculiar construction, heated by a lamp C. The engine A
is arranged under the table of the sewing machine or other working machine to
which it is applied, so that the piston rod is connected directly to the crank pin of
the driving pulley and flywheel, the latter thus serving as flywheel both to the
engine and to the sewing machine. The steam supply pipe L is provided at E
with a shut off valve arranged in a convenient position on a level with the table,
so that the engine can be readily stopped by turning the handle of the valve. The
steam generator B is fixed on a frame above the table so that the lamp serving to

of the generator is shewn at Figs. 2 and 3. It is provided at its lower end with
an annular extension b into which projects the cylinder of the lamp c so that the
heat radiated from the latter is usefully employed in generating steam in the
part b. The hot gaseous products of combustion pass from the top of the chimney
glass through the tube o into the hollow chamber d and thence through a number
of tubes e leading up through the water and steam space of the generator to the
open air. A recess f in the top of the generator may be utilised for beating food
or other substances. For preventing loss of heat by radiation, the generator is
surrounded by a jacket of a bad conductor of heat, such as felt. On the tubular
extension b, is fitted a reflector G which can be raised or lowered so as to adjust
the extent of illumination of the table. The arrangement and form of the heating
tubes e may be variously modified, thus they may be straight, serpentine or spiral.
The exhaust steam can be either led into a condenser of any known construction or
may
be otherwise dealt with.

The advantages of the above described motor are:
First. The employment of the lamp both for heating the generator and for
giving light, as also to a certain extent for hoating the work room.
Second. The facility with which this motor engine can be applied to a sewing
machine or other working machine in such manner that it forms no obstruction
when the machine is worked by the treadle.
Third. The absence of danger in working and the dispensing with special
attendance.

ARRANGEMENT OF MOTOR ENGINE WITH STEAM GENERATOR FOR DRIVING SEWING
MACHINES AND OTHER MACHINERY REQUIRING SMALL POWER. A communication
to me from Louis Heinrici residing at Zwickau, Saxony, in the German Empire.
This invention relates to a motor engine and steam generator, more particularly
adapted for operations requiring a small power, such as for driving sewing machines.
The construction will be readily understood on reference to the accompanying
drawings, fig. I of which shews the motor engine, as applied to a sewing machine.
It consists of a small steam engine A with oscillating cylinder supplied with steam
from the generator B of peculiar construction, heated by a lamp C. The engine A
is arranged under the table of the sewing machine or other working machine to
which it is applied, so that the piston rod is connected directly to the crank pin of
the driving pulley and flywheel, the latter thus serving as flywheel both to the
engine and to the sewing machine. The steam supply pipe L is provided at E
with a shut off valve arranged in a convenient position on a level with the table.
so that the engine can be readily stopped by turning the handle of the valve. The
steam generator B is fixed on a frame above the table, so that the lamp serving to
beat the same, also serves to give the requisite light for working. The construction
of the generator is shewn at figs., II and III. It is provided at its lower end with
an annular extension 6 into which projects the cylinder of the lamp C, so that the
heat radiated from the latter is usefully employed in generating steam in the
part b. The hot gaseous products of combustion pass from the top of the chimney
glass through the tube c into the hollow chamber d, and thence through a number
of tubes e leading up through the water and steam space of the generator to the
open air. A recess f in the top of the generator may be utilised for heating food
or other substances. For preventing loss of heat by radiation, the generator is
surrounded by a jacket of a bad conductor of heat, such as felt. On the tubular
extension b is fitted a reflector G which can be raised or lowered, so as to adjust
the extent of illumination of the table. The arrangement and form of the heating
tubes e may be variously modified; thus, they may be straight serpentine or spiral.
The exhaust steam can be either led into a condenser of any known construction or
it may be otherwise dealt with.
Fig. IV shews the same construction of steam generator as above described
with a water level indicator applied thereto. This consists of a float S having a
stem K that passes up into a strong glass tube, connected steam-tight to the top of
the generator and having its interior in communication with the steam space
thereof, so that the position of the rod of the float, moving freely up and down in
the tube, will indicate the level of the water.
The float rod is guided in its motion by passing through the guide n.
The glass tube g is protected and secured by a brass casing having two
longitudinal slots , as shewn in the cross section at Fig. V., and screwed steam
tight into the socket m, fixed on the top of the boiler.
The advantages of the above described motor are:-
First. The employment of the lamp both for heating the generator and for
giving light as also to a certain extent for heating the work room.
Second. The facility with which this motor engine can be applied to a sewing
machine or other working machine in such manner that it forms no obstruction
when the machine is worked by a treadle.

page_text: Third. The absence of danger in working and the dispensing with special
altendance.
Having thus described the nature of this, invention and in what manner the
same is to be performed, as communicated to me by my correspondent, I claim :-
First: An improved arrangement of motor engine for driving apparatus or
machines requiring small power, consisting of the combination of an oscillating
steam engine with a steam generator constructed as herein described and heated
by a lamp, which may, at the same time, serve to give light to the workman,
substantially as herein described.
Second: The peculiar construction of steam generator herein described with
reference to Figs II and III of the drawings, having a lower cylindrical extension
enclosing the chimney of the lamp, the hot combustion gases from which pass up
through a series of smoke tubes leading through the water space of the boiler.
In Witness whereof, I the said, Friedrich Carl Glaser have hereunto set my hand
and seal this thirty first day of March in the year of our Lord, one thousand, eight
hundred and eighty-four.
