FUMIGATING DEVICE Fil ed OCT.. 26, 1929 Patented Aug. 18, 1931 UNITED s'rares Artnr' ori-ice EDWARD THORNDIKE LADD, F LEVISTON, NEW YORK, ASSIGNOR TO ISCO CHEMICAL COMEANY, INC., OF NIAGARA FALLS, NEV ORK, A CORPORATION OF NEW YORK FUMIGATING DEVICE Application led October 26, 1929. VSerial No. 402,613.

My invention relates in general to fumi gating devices, and more particularly to a hermetically sealed chest within which garments may be placed for treatment or storage.

he principal object of my invention has been to provide a device so designed that f when the cover thereof is closed, a definite charge of liquid or gas will be released within it.

Another object has been to provide a fumigating unit which may be easily removed from the chest forrenewal.

Moreover, my fumigating unit is so de? Fig. 2 is a sectional view thereof, taken on' line 2-2 of Fig. 1.

Fig. 3 is a fragmentary, perspective view of my fumigating chest.

Fig. 4 is a fragmentary, vertical, sectional view, taken through the well for the fumigating unit. Y i

Fig. 5 is an enlarged fragmentary, seetional view showing suitable means for hermetically sealingr the cover.

My device comprises a chest 10, of wood or other suitable material, having a hinged cover 11. Suitable means such as a strip 12 of resilient metallicl or rubber material may be secured either to the under co-acting edge of the cover or the upper co-acting edge of 45 the chest so as to hermetically seal the joint between the cover and the chest when the cover is lowered.

In one corner of the chest there is providn ed a well 15 which is preferably formed of a blockof wood 16 into which the well is drilled or bored. The well is provided with a plurality of lateral or upwardly inclined apertures 17 in oneV or both of the exposed surfaces. The well is of such a size and depth as to receive the fumigating unit 20.

The fumigating unit comprises a casingl 21 formed of suitable metal and provided at its upper edge with screw-threads for the screw-threaded reception of a cap 22. The cap 22 slidably carries a plunger 23, having a foot `24@ secured at its inner end, and an operating button 25 secured at its outer end. The bottom wall 26 of the unit is provided with a central aperture 27 through which the fumigant escapes. A screen 28 is preferably arranged in the bottom of the unit whereby particles of the broken glass ampoule 29, used with my device, may be retained within the casing 21. Any suitable fumigant may be used in the ampoule, and depends somewhat upon the treatment to be given the contents of the chest, but I preferably use chlorpi'crin The parts of the fumigating unit are so proportioned in relation to the depth of the well 15 that the operating button 25 will project upwardly to a position where the cover 11 will canse it to be depressed before such cover has reached its closed posi.-

tion, whereby the device is operated.

Obviously, after the garments to be treat- Y ed have been placed within the chest, and an ampoule 29 containing the suitable liquid or gas has been placed within the unit, the cap 22 of the unit is screwed down and the unit is placed within the well 15. The cover Y 11 of the chest is now closed with a positive pressure which causes the foot 24 carried by the rod 23 to be forced into the upper end of the ampoule, thus breaking the same. The gas produced by vaporization of the liquid will pass through the opening 27 of the casing 21 and out through the openings 17, charging the chest and its contents with vapors of the agent used.

. 1f the garments so treated are to be stored, the chest is, of course, kept closed, whereby the fumigating vapors will be retained with` in the chest and the garments contained therein. If, however, the garments are to be treated to disinfect or moth-proof them, they are allowed to remain Within the chest for a suitable length of time after which they are removed from the chest. The fumigating unit is removed from the Well and the cap 22 is unscrewed, whereupon the broken fragments of glass may be removed by dumping them out, and Without their coming in contact with the hands. A new ampoule may 'be placed Within the body, the cap 22 screwed thereon, Vand theunit placed Within'the Well.

The device is then ready for further use.

lhile I have shown my device as applied to the body of the chest 10i, it .is obvious-that it may be carried in any suitable manner by the cover, and the same advantages derived. This, andother modii'ications of the details herein shown and described may be made with out departing from the spirit of my invention or, the scope of the appended claimf, and l do not, therefore, Wish to be limited to the exact embodiment herein shown and described, the form shown being merely a preferred embodiment thereof.

`Having thus described my invention, What I claim is:

1. A fumigating device, comprising a chest, a cover for the chest, a umigating unit carried b v the chest, comprising a single-piece, hermetically sealed, brealzable container, and means engagea'ble with said container for breaking the same when the cover is moved to its closed position.

2. A tumigating device, comprising a chest, a cover for the chest, a fumigating unit carn ried by the chest, comprising a casing having an outlet opening, a screen disposed over the opening, a glass ampoule contain-edwithin the casing and resting upon thescreen, a cap foi-the casing, a slida'ble plunger carried by the Vcap having a foot for engagement With the ampoule, and a button carried at the upper end of the plunger for engagement 'with the cover of the chest w' ien the same is moved to its closed position, whereby the amponle is broken.

In testimony whereof, have hereunto signed my name.

EDWARD THQRNDKE LADD.
