FORMALDEHYDE-LAM P.
SPECIFICATION forming part of Letters Patent No. 599,849, dated March 1, 1898. Application filed April 14;, 1897. $erial No, 632,159. (No model.)
To aZZ whom it may concern:
Be it known that I, RICHARD-P. KUHN, a citizen of the United States of America, residing at Alexandria, in the county of Alexandria and State of Virginia, have invented certain new and useful Improvements in Lamps for Generating Gas, of which the following is a specification, reference being had therein to the accompanying drawings.
This invention relates to certain new and useful improvements in lamps, and more particularly to that class which are adapted to generate gas.
The object of this invention is to provide an exceedingly cheap and simple form of lamp which is adapted to generate formaldehyde. This gas is poisonous to the germs of all contagious diseases, and it also destroys moths.
Another object of this invention is to provide a lamp-which is useful to disinfect apartments infected with contagious diseases, and in using the same the room is closed up tight;
The garments and bedclothing to be disinfected should be also placed or arranged around the room in such a manner that the gas can penetrate freely all parts.
With these objects in view my invention consists in the particular construction of the various parts and in'the novel manner of combination or arrangement of said parts, all of which will be described hereinafter and pointed out in the claims.
In the drawings forming a part of this specification, Figure l is a side elevation showing my invention as in an operative position. Fig. 2 is a cross-section taken on a plane just above the perforated disk. Fig. 3 is a longitudinal vertical section. Fig. 4 is a side elevation, with a part broken away, showing the lamp when packed. Fig. 5 is a detail View of the hook and catch.
Referring to the drawings, A representsa pan, having secured therein an inverted pan B, which is provided with a coarse-gauze bottom a. This pan is filled with mineral wool or any other suitable material which is not fusible and is adapted to absorb alcohol. The pan A is provided with a lip b,which affords means for the water between the two pans to run off, thus preventing the same when poured in the groove between the pans from raising to a sufficient height to enter the pan B.
larger end of the sides.
This lip is also adapted to support the flue 0 when in a raised position, said flue consisting of a cylinder hinged within the outer pan approximately near the lip, having an opening covered with mica tonote combustion should it take place, and provided with a swage c at its center to support a perforated disk D, secured therein by asbestos cement. This disk is made of asbestos-board saturated with a solution of chlorid of platinum and alcohol. Other liquors may be used in connection with the chlorid of platinum, but the best result has been obtained by the use of alcohol, This disk may contain a sufficient number of grains of platinum to give the desired result.
Secured within the swage c and extending across the flue are braces made of copper wire to support the center'of the disk, and below the swage is a line of perforations d, arranged around the entire flue at a sufficient height from the bottom to prevent combustion and to admit the oxygen and hydrogen. When heating the said disk, the flue rests on the support secured to the-outer pan, thus admitting the required amount of draft, and when the disk is sufficiently heated the said support is removed and the flue drops in position, the lower edge being immersed within the water, thus forming an air-tight seal.
The flue is provided with a cone or conicalshaped top E, having a handle F, and secured in the top thereof an adjustable sleeve G, said sleeve provided with a lug e, which engages the slot f in the said top. This top increases the draft to such an extent that twice the amount of alcohol is consumed in the same time, thus producing twice the amount of gas. Care must be taken not to increase the draft to such an extent that it will cause combustion. The flue is also provided with a catch g, which consists of an oblong piece of metal having V-shaped sides bent at right angles thereto, and at the end nearest the greatest width of the sides is secured a lip at .right angles to the said piece and sides, the length of which is about one-half the Width of the ed to receive and secrete the hookh, which is secured in the bottom of the pan.
The cylindrical cover or hood H is provided with a handle 2' and is of a sufficient length and width to cover the entire flue whenthe This catch is adaptadjustable sleeve is pushed in and the cone top inverted. The lower edge of the cover reaches the bottom of the groove formed by the two pans and is held therein by the hooks jj, engaging the catches 7t 70. I11 the top of the hood is an aperture Z to prevent the water from being drawn up by suction into the pan B.
Then the lamp is to be used, put into the outside pan about one inch of water. The flue is then raised and the required amount of alcohol is poured over the mineral wool. This readily absorbs the alcohol and prevents any free alcohol from spilling should it be tipped over. It also prevents undue action of the flame should by chance it become ignited. The flue is replaced so that the edge rests on the support in front of pan and the alcohol lighted. The lamp is allowed to burn freely until the platinized disk of asbestos begins to glow slightly, when the support is pushed aside, permitting the flue to fall in place. Now put 011 the cover or hood, and after about thirty seconds remove and observe whether the alcohol has ceased to burn. If not, replace the hood, and again after thirty seconds remove, when the platinized disk should begin to glow and formaldehyde be given off. Then put on the cone top and permit lamp to generate formaldehyde until all of the alcohol is evaporated.
It will thus be seen that I provide an exceedingly cheap and simple form of gas-generator which will sufliciently perform all of its intended functions.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. In a lamp, the combination of an outwardly-fiarin g pan having secured in the bottom thereof an inverted pan provided with a gauze bottom and adapted to receive a suitable absorbing infusible material; the outer pan provided with a lip said lip so constructed as to allow the waterto run oil. before rising to a suiiicient height to enter the inner pan, a fine hinged within the groove formed by the sides of the said pans, and adapted to rest in the said lip when in a raised position, substantially as shown and described.
2. In a lamp, the combination of a line hinged within the groove formed by the outside of the inner pan and the inside of the outwardly-flaring pan, approximately near the lip, said flue consisting of a cylindrical tube having at its center a swage and secured within said swage, suitable supports extending across the flue, a perforated disk resting on said swage and support, substantially as shown and described.
3. In a lamp, the combination of an outwardly-flaring pan provided with a lip having secured therein an inverted pan, a groove formed by the sides of the said pans, said groove adapted to be filled with water, afiue supported within the outer pan, the lower edge of which rests when in the lowered position in the said groove and water, and when in the raised position in the said lip, substantially as shown and described.
l. The combination of a lamp having a fine provided with a movable cone or conicalshaped top, said top having an adjustable sleeve, said sleeve adapted to be pushed in the said cone or conical-shaped top and the top inverted when desired to pack the said lamp, substantially as shown and described.
111 testimony whereof I affix my signature in presence of two witnesses.
RICHARD P. KUI-IN.
