Improvements in Vaporizers.
I, HENRY PITT ROBERTS of Jamestown, in the County of Chautauqua and
State of New York, United States of America, Merchant, do hereby declare the
nature of this invention to be as follows:-
11
This invention relates to a certain new and improved vaporiser.
The object of the inventor is to provide an improved vaporiser exceedingly
simple, cheap, durable, and compact in construction, and adapted for use in sick-
rooms, bedrooms, water-closets, railroad-cars, etc. These objects are attained by
and this invention consists in certain novel features of construction and in com-
binations of parts hereinafter more fully described.
According to one construction the vaporiser is particularly adapted to rest on
some object and allow the deodorizing-liquid to evaporate and diffuse throughout
the air of the apartment. The base of the vaporiser is preferably flat on the
bottom. This base has a central cylindrical receptacle open at the top and an
outer reticulated cylindrical casing extending between and rigidly secured to said
base and an upper cap. There is a tubular, preferably reticulated, wick carrier,
the exterior of which is covered by a tubular wick stretched thereon.
This carrier extends through a circular opening in the top cap, its lower end
surrounded by the wick extending into the before mentioned vessel. The opening
in the upper cap is surrounded by an annular screw threaded flange, and the wick
carrier is rigidly secured to and depends from a screw cap that covers the opening
and is screwed to the said flange of the cap. This cover is provided with an
opening communicating with the upper open end of the wick carrier, and this
opening is normally closed by a removable screw closure. Any suitable volatile
deodorizing liquid is poured through the opening in the wick holder into the vessel
below, after which the screw closure is secured in place and the article located in
the place it is desired to deodorize. The deodorizing liquid is drawn up by the
wick extending into the vessel, and by capillary action saturates the entire wick.
and becomes thereby diffused throughout the air of the room as the same passes
through the perforated casing in contact with the wick.
According to a modified construction the vaporizer is so constructed that it can
be secured to the wall of a water closet of a railroad car or other place and
comprises the same essential features as the vaporizer hereinbefore referred to.
A pipe extends from the bottom of the lower cap which forms a receptacle to
the urinal. The wick carrier instead of being perforated and open at the bottom.
is imperforate and closed at the bottom to form a vessel, and a long strip of wick is
employed with its two ends extending from the top down into the interior of the
wick carrier or vessel from opposite sides, the wick extending longitudinally on the
exterior of the carrier and across the bottom of the same. The liquid being.
placed within the wick carrier or vessel, as before described, the wick becomes
saturated and some of the liquid drops into the bottom cap and, together with the
fumes thereof passes down into the urinal and deodorizes and purifies the air
around the same.
Secured to opposite ends of the apparatus are rings or supporting brackets to
support the same.
It is evident that various changes might be made in the form and arrangements
dosomibed without departing from the spirit and scope of my
norto

page_text: invention; hence I do not wish to limit myself to the precise construction herein
set forth.

Fig. 3 is a cross section.
Fig. 4 is a detached elevation of the wick and its carrier.
Fig. 5 is an elevation of a somewhat modified construction of the vaporizer.
Fig. 6 is a longitudinal section.
The article illustrated in Figures 1 and 2 of the drawings is particularly adapted
to rest on some object and allow the deodorizing liquid to evaporate and diffuse
throughout the air of the apartment. The base a of the article is preferably Hat
on the bottom. This base has a central cylindrical receptacle b open at the top.
c is the top or upper end of the article, and d is the reticulated outer
cylindrical casing extending between and rigidly secured to said base and upper
cap c.
dis the tubular, preferably reticulated, wick-carrier, the exterior of which is
covered by the tubular wick e stretched thereon. This carrier extends through a
circular opening in the top cap c, with its lower end surrounded by the wick
extending into vessel. The opening in the upper cap is surrounded by an
annular threaded flange, and the wick carrier is rigidly secured to and depends
from a screw-cap f covering the opening and screwed on said flange of the cap c.
This cover is provided with an opening g into the upper open end of the wick
carrier, and this opening is normally closed by the removable screw-closure h.
Any suitable volatile deodorizing liquid is poured through opening g and the wick
holder into vessel b, the closure is then secured in place and the article located in
the place it is desired to deodorize. The deodorizing liquid is drawn up by the
wick extending into the vessel b, and by capillary action saturates the entire wick
and is thereby diffused throughout the air of the room as it passes through the
perforated casing in contact with the wick.
The article shewn in Figs. 5 and 6 is particularly adapted for securing to the
walls of the water-closets of railroad-cars or other places, and comprises the same
essential features as the article shewn in Figures 1 and 2. A pipe i extends from
the bottom of the lower cap, which forms a receptacle to the urinal.
The wick carrier instead of being perforated and open at the bottom is
imperforate and closed at the bottom to form the vessel b, and a long strip of wicke
is employed with its two ends extending from the top down into the interior of the

page_text: wick carrier or vessel from opposite sides, and the wick extending longitudinally
on the exterior of the carrier and across the bottom of the same.
The liquid
being placed within the wick-carrier or vessel, as before described, the wick
becomes saturated and some of the liquid drops into the bottom cap and, together
with the fumes thereof, passes down into the urinal and deodorizes and purifies the
air around the same.
kk are rings or supporting brackets secured to opposite ends of the article to
support the same.
It is evident that various changes might be made in the form and arrangements
of the parts described without departing from the spirit and scope of my
invention; hence I do not wish to limit myself to the precise construction herein
set forth.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. A vaporizer comprising a vessel to contain the liquid, one or more wicks
held extending into said vessel, and a reticulated casing surrounding the wick and
allowing the air free access thereto, as set forth.
2. As a new article of manufacture, a vaporizer comprising the reticulated
casing, end caps for the same, a removable wick support in the casing, and a
wick on the exterior of the carrier extending into the liquid vessel, as set forth.
3. As an article of manufacture, a vaporizer comprising a vessel to contain the
liquid, a wick extending into said vessel and exposed to the air throughout its
entire or substantially its entire length, a support for and upon the exterior of
which the wick is located, and an outer open casing, substantially as described.
4. As an article of manufacture, a vaporizer consisting of the rigidly-connected
end caps, the liquid receptacle being in the lower cap, the hollow wick-carrier
between and supported by one or both of said caps, and a wick on the exterior of
said carrier extending into the liquid-receptacle, substantially as described.
5. In combination, the perforated casing, end caps therefor, a hollow wick-
carrier depending from the upper cap, a wick on the exterior of said carrier
extending into the liquid-vessel, and a cap for closing the vessel, substantially as
described.
6. In a vaporizer, the combination of the liquid-holding vessel, the hollow wick
extending thereinto, a receptacle in the bottom of the vaporizer beneath said
wick, the pipe extending down from and draining said receptacle, and the securing
rings or brackets for supporting the article, for the purpose set forth.
