HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co, Patent Agents,
Southampton Buildings, London, "IMPROVED HEAT-REGULATING APPARATUS TO
BE USED IN CONNECTION WITH STEAM OR OTHER ENGINES "
[a communication
to him from abroad by Jules Garadot, of Neuville-sur-Saône, in the republic of
France]
This invention relates to an improved heat regulating apparatus to be used in
connection with steam or other engines
In carrying the said invention into practice I provide two metal cylinders having
two chambers and designed to receive steam from a generator, I also provide a piston
serving to increase or decrease the capacity of one of the said chambers; a rotary
endless screw is arranged vertically in the centre of one of the metal cylinders and
serves to cause the piston to ascend or descend by means of suitable gear-wheels
regulated by means of a governor. I also provide a movable rod fixed to the said
piston and sliding by means of a kind of stuffing box through the cover of the
cylinder and along a graduated scale; this rod indicates the quantity of steam
contained in the heat regulating apparatus. A metal tube or pipe is provided
through which pass the gases from the fire-box, which thus serve to heat the two
cylinders. This pipe is situated inside one of the cylinders provided with radiating
wings or plates offering a large heating surface to the steam contained in the
chambers. An aperture or port is formed in one of the metal cylinders for the
admission into the heat-regulating apparatus of the steam from the generator, and-
a pipe is arranged to conduct the steam from the heat regulating apparatus to the
motor cylinder. I further provide a slide valve for alternately opening and
closing the said aperture or port in order to put the said heat regulating apparatus
in communication either with the generator or with the cylinder of the motor.
The slide rod is subjected to an alternate motion by means of an excentric and
transmits the said motion to the said slide valve in such a manner that the said
valve, towards the end of the stroke of the piston of the motor, opens and closes the
said aperture or port rapidly enough for the steam from the generator, after

before the end of its stroke; a waste cock and a damper for limiting the
introduction of the gases from the fire box into the aforesaid tube or pipe are also
provided, as well as a pipe for introducing steam from the generator behind the
piston of the heat regulating cylinder
The heat regulating apparatus as applied to a steam-engine constitutes a metallic
receptacle of variable capacity heated by the gases from the fire-box. By its use
no direct communication between the generator and the motor cylinder can be
established; it thus receives automatically directly from the generator, and in
suitable quantity according to the requirements of the engine, the saturated steam
and the liquid carried away mechanically therewith. This mixture is heated in the
said apparatus until the liquid portion of the mixture is completely converted
into steam and is superheated if required to any desired point. This steam is then
transmitted by means of the slide valve to the motor cylinder and is admitted
thereto at full pressure during the whole length of the stroke of the piston and
escapes from the said cylinder through apertures or ports always open
The improved heat-regulating apparatus is also applicable to compressed gas
engines. In some cases the pistons employed in engines in which superheated
steam and compressed gases are utilized, do not answer well for the purposes of
this invention and allow some of the superheated steam or compressed gases to
escape. In this case the piston will have to be replaced by a piston analogous to
that of a "Deleuil " air pump the use of which is based upon the resistance to the
escape of gases in capillary tubes.
"
It will then be possible to heat the motor cylinder directly with the gases from
the fire-box, the said cylinder thus forming an integral and essential part of the
heat-regulating apparatus.

The form, dimensions, and arrangement of the improved apparatus may be
somewhat varied if desired, according to whether it is required for navigation,
locomotion, or other purposes
