COMPLETE SPECIFICATION.
Improvements in Vaporizers.
I, JUSTUS OSMAN WOODS, of No. 128 East Twelfth Street, of the City, County
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 in which the quantity of fluid to be evaporated
is supplied by capillary absorption or syphonic attraction and consists of a closed
reservoir formed like a bottle with an opening on the top for filling it with fluid, and
another opening or aperture near the bottom for the outflow; in connection with this
outflow is an oblong bulb hollowed on its upper side to form a small trough, said bulb
projects beyond the periphery of the reservoir or bottle, the object of which will be
hereinafter more fully explained; it also consists of an evaporating apron arranged
above the trough and means for supplying fluid to said evaporating apron, as 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 plan or top view of my vaporizer.
Fig. 2 represents a front view of the same.
Fig. 3 represents a vertical central section.
A, is the closed reservoir; in this instance it is made of glass and is provided with
an opening A' at the top, closeable by a stopper A². On the outside of the periphery
of the reservoir or bottle A, is formed an oblong bulb A3 (as shown in Figs. 2 and 3
of the drawings) hollowed on its upper side to form a small trough or receptacle A*,
for the fluid; from this trough a tube A° projects slantingly downwards into
the reservoir A, with its lower end A6, closed, as the reservoir cannot otherwise be
blown. When prepared for use the closed tube A³ is opened so that fluid may flow
from the reservoir into the trough.
B, is the evaporating apron arranged above the opening C, so as to prevent the
dripping of the fluid from said apron. In this instance the apron is secured to a volute
frame B¹, which rests upon the top of the reservoir or bottle.
C, is the opening or aperture near the base of the closed reservoir through which
fluid is supplied by capillary attraction, to the evaporating apron.
D), is the fluid conductor which is secured to the lower end a of the evaporating
apron and extends all the way around it as shown in Fig. 2 of the drawings; the
ends b, b, of said conductor are passed through the aperture C, into the closed reservoir,
from which the fluid is drawn.
Fluid is put into the reservoir through the opening in the top (which is closed by
an air tight stopper) or through the opening near the base, until the reservoir is
filled. The fluid will then flow into the tube A5, and air enters the reservoir until the
fluid has risen above the aperture Aº, when it will cease, being kept back by the pressure
of the atmosphere against the partial vacuum left above the fluid in the reservoir.
The fluid in the reservoir and trough is then conducted by cords or strips D, by
capillary attraction and syphonic action to the apron above, and is evaporated by the
surrounding air.
Having now particularly described and ascertained the nature of my said inven-
ion and in what manner the same is to be performed, I declare that what I
claim is
1st. In combination with the closed reservoir of the discharge opening near the
ottom of said reservoir and the evaporating apron located above said opening.

page_text: 2nd. In combination with the closed fluid reservoir of the discharge opening near
the bottom of said reservoir, the evaporating apron located above said opening and
the conducting cords, substantially as and for the purpose hereinbefore set forth.
3rd. In combination with the closed fluid reservoir of the evaporizing apron
provided at its lower end with a fluid conducting cord, substantially as hereinbefore
set forth.
4th. The closed reservoir A provided with an opening A' at its top, the discharge
opening near its bottom, the oblong bulb A³, the trough A* and the tube A* combined,
substantially as hereinbefore set forth.
Dated this 25th day of September 1890.
