PROVISIONAL SPECIFICATION left by Joshua Kidd at the Office of
the Commissioners of Patents, with his Petition, on the 7th January
1858.
I, JOSHUA KIDD, of 6, Bridge Parade, Bristol, in the County of Somerset,
Civil Engineer, do hereby declare the nature of the said Invention for " IM-
PROVED APPARATUS FOR REGULATING THE PRESSURE AND SUPPLY OF STEAM, GAS
OR OTHER RARIFIED OR COMPRESSED BODIES, AND FOR CAUSING MORE PERFECT COM-
BUSTION OF THE GASES PROCURED FROM COAL, AND INCREASING THE HEATING AND
ILLUMINATING POWER OF THE SAID GASES," to be as follows:-
My improvements consist in the application of a valve with disc or pressure
surface, made to move through a socket in a box or case, and balanced on
the pressure for regulating the pressure and supply of steam, gas, or other
rarified or compressed bodies, at the bottom of which box I place a quantity
of spirits of turpentine, coal naptha, or other volatile bodies, over which
volatile bodies I pass the coal gas; the effluvia from the volatile spirits com-
bines with the coal gas, and increases the heat and illuminating power, and
causes more perfect combustion of the said gases, as shown in the accompany-
ing Drawings; but I do not confine myself to the exact details of such outline
Drawings, as they will be more fully explained in my Complete Specification.

page_text: I construct, for securing my object, a portable apparatus, of any convenient
shape, square or circular, as my machine for regulating such pressure and
supply as aforesaid, and I proceed to explain the outline Drawings.
Fig. 1 represents a side elevation of my improved apparatus with one side
off; B is the inlet; C, the outlet; D, the disc; E, the valve working against
the aperture F; G, steadying wire attached to valve and disc; H, lower
chamber partly filled with spirits of turpentine, coal naptha, or other volatile
bodies; I, I, holes to admit the gas to pass through the circular chambers
J, J, J, which chamber is constructed in a continuous worm-like formation;
K, the outlet of the circular chamber J, J, J.
Fig. 2 is a modification of Fig. 1, and represents a side elevation of appa-
ratus for regulating the supply of steam and hot air, with the sides off. B is
the inlet; C, the outlet; D, the disc or 'pressure surface; E, the valve; F,
the aperture; G, steadying wire connecting disc and valve; L, weights for
regulating the pressure; M, safety valve; N, steam escape for safety valve;
O, balance levers..
Having given an outline of my Invention, first, I claim the application of a
valve with a disc or pressure surface, made to move or slide through a socket
in a box or case, and balanced on the pressure for regulating the pressure and
supply of steam (as shown in the accompanying Sketch of Fig. 2), and every
application of such valve for such purposes.
Secondly, I claim. the application of a disc and valve balanced on the pres-
sure of gas in combination with a reservoir or receptacle containing spirits of
turpentine, coal naptha, or other volatile bodies described in Fig. 1, for the
purpose of regulating the pressure and increasing the brilliancy of coal gas,
and for impregnating air with the vapours emitted from volatile spirits,
together with the general arrangement and combination of parts.
