COMPLETE SPECIFICATION.
Improvements in Vaporizers.
1, JUSTUS OSMAN WOODS, of No. 128 East 12th Street, in the City and State of
New York, United States of America, Gentleman, do hereby declare the nature of this
invention, and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
My invention relates to Vaporizers, wherein the quantity of fluid to be evaporated
is contained in a trough fed from an adjacent closed reservoir, from which the quantity
of fluid in said trough is regulated by the equilibrium between the weight of fluid in
said reservoir, and the external air pressure, by means of an aperture or apertures
near the bottom of said reservoir, and in which the quantity of fluid evaporated from
the said trough is also regulated. And my invention consists in certain means for
regulating such evaporation, fully set forth and claimed in this specification.
In order that persons skilled in the art may understand, construct and use my
invention, I will proceed to describe it, referring to the drawings, in which
Fig. 1 represents a perspective view of a closed receptacle with my improvements
applied thereto.
Fig. 2 represents a vertical central section of the same.
Fig. 3 represents a side elevation with parts broken away to show the arrangement
of the evaporator.
and
Fig. 4 represents a side elevation of my invention, showing the evaporator strips,
Fig. 5 represents a vertical central section of the same, showing the slitted apron.
A represents the closed receptacle, and it is provided with a trough B for the fluid;
this fluid is to be drawn out from the trough by means of evaporators C, as shown in
the drawings. D is a rack securely fastened to the closed receptacle; a, al are hooks
and b, are rods or rollers. These rods or rollers are for the purpose of suspending
and adjusting the evaporator U (as shown in Fig. 3 of the drawings) so as to
regulate the quantity of fluid to be drawn out of the trough by the evaporator; the
rate of the flow or drip will depend upon the height which the fluid must ascend frou
the surface of the fluid in the trough, which rate in such case increases as the roller
is lowered and vice versa.
Figs. 1 and 2 of the drawings show the evaporator attached to the roller b', which
is located in the trough B; the evaporator is suspended from the trough with one end
of it in the fluid in the trough, and the other end hanging over the side.
Dis the flange on the inside of the trough B, with which the claws or hooks
attached to the evaporating apron C engage, to support the apron when it hangs over
the side of the trough.
C is the evaporating apron.
E are the strips, into which the upper end of the evaporating apron C is slitted,
and E' are evaporating strips; F are the hooks or claws, which are attached to each
strip to hold it in the evaporating trough B, on flange D'. G are straps attached to
projections H on the fluid reservoir to suspend it by.
The fluid in the trough is also conducted by the strips E and El, by capillary
attraction and syphonic action, and is evaporated by the surrounding air.
In case too rapid evaporation should occur, some of the strips E and E' are removed
from the trough B.
The quantity of fluid evaporated is thus regulated, to a nicety.
The closed receptacle A has an orifice c at the top for filling it with fluid, and an
orifice c', at or near the bottom thereof to be used as an outflow into the trough.
While the receptacle A is being filled with fluid, the orifice or outflow c¹ should be
closed after the receptacle is filled the orifice c is closed and orifice c' opened, the
Huid will then flow into the trough until the orifice c¹ is covered by it so that no more

uncover the orifice again, by the pressure of the atmosphere against the partial
vacuum left above the fluid in the reservoir. The receptacle A and the evaporator C
may be of various forms. The hole or orifice c may be omitted, as shown in Fig. 4
of the Drawings.
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
I claim is
1st. The combination in a closed evaporating apparatus, of a receptacle having
orifices C, c', communicating with the interior thereof, with a trough having an
evaporator connected with it, substantially as herein before set forth.
2nd. In an evaporating apparatus, the combination of the receptacle having
orifices c,
e communicating with the interior thereof, with a trough, having an
evaporator connected with the trough and rollers b, to regulate the quantity of
fluid to be drawn out of the trough, substantially as specified.
3rd. The combination with the closed fluid reservoir of the trough beneath, the
discharge aperture near the bottom of said reservoir, and within the evaporating
trough, the evaporating strips and the flange for retaining the conducting evaporating
strips in said trough, all combined and arranged, substantially as and for the purposes
specified.
4th. The combination of the covered reservoir provided with the discharge
aperture c', the evaporating trough, provided with the slitted ends of the evaporating
apron to regulate the quantity of fluid for evaporation, substantially as specified.
