operating auto matically upon the locking of the wardrobe by means of the pressure bar. To this end the door carries a plunger tends therethrough and is provided on its outer end withso located as to be engaged'by a short :arm 22 which eXtends laterally from the pressure bar and which, when the pressure bar is swung around to the locking position, engages the knob 21 and thrusts the plunger inward against the tendency of a spring 23 to hold the same in its outward position. The liquideexpelling apparatus comprises a. pump, vided with an inletpassage 25 having there in a valve 26 which opens to permit theflow of fluid. therethrough. from a tank 27 when the piston 28 moves 24. The pump is provided 'alsowith' an outlet passage 29 having therein a Valve 30. which opens to permit the passage of. liquid from the cylinder upward when the piston is moved inward. Thestem 31 ofthe piston 28'extends forward or toward .the front of thewardrobe and has a downturned end .32,

-wheel38 which,

vided' with a handle 39. lifovement'from' the bevel gear wheel 38 is transmitted'and ranged to be engaged by and moved inward by the inner end '33 ofthe plunger 20 when the'plunger is forced in .by the engagement therewith ofthe arm 22 of the 'pressure bar 15. ,A spring 34 tends to draw the piston When the arm engagement with the plunger 20 by the un-, locking of the pressure bar preparatory to opening the wardrobe, the plunger and pis-v ton are at first prevented from-moving out under the, influence of the springs 23and '34 by a. latch 35 which is pivoted at its inner end to a 'hanger or other support 36 and'has its forward end'bent downward to form, a hook 37, this hook having an inclined face so that the plunger 20 may pass under the point of the hook and lift the latch when the plunger is being n1oved,.inward. ,The object of thus locking the plunger 30 is that the door may not be opened vuntil the'means pelling from the wardrobe the fumes of the exterminating substancehave been operated. a At some convenient point, as upon the end. of the showinthere is arranged a centrifugal or other form of blower 371' which may be operated by the turning of a bevelgear for this purpose, is proreduced by means of a bevel pinion 40to a shaft 41 which eXtendst-hrough the rotary part of the blower 371. The outlet 42 of the blower is connectedfto a pipe 43' which opensinto the wardrobe and isiprovided with a valve 44 which is normally held down by. a spring 45 coiled about a rod- 46 which 20- which; eX.-

a knob 21, this /knob being wardrobe through the Cylinder. 24 of which is pro outward in the cylinder 22 is moved out of wardrobe and exterior thereto, as

rod carries also, upon its upper end,'another valve 47 which is normally closed but which, when open,; establishes communication be-- tween an outlet pipe 48 and a pipe 49 which is located in and opens into the upper part ofthe wardrobe. It is evident that the operation of the blower, by revolving the gear 38, would not create a flow ormr into the pipe 43, nor a flow of air outward through pipe 49 so long as the valves 44-and 47 remained closed,- It is also evident that these valves should normally befirmlyfseatedin order that the wardrobe may be maintained perfectlylair tight. For this re ason the spring 45, is made compara-; tively strong, and. positively, acting me chanically operated means are opening these valvesat the proper time. To this end the apparatus is soarranged that the first few revolutions of the rod41 serve to operate ,a device for. lifting the valves from theirseats by moving the, valve rod 46 upward. This rod-lifting; device comprises a worm gear 50 which 'is loosely mounted on a shaft 50 and revolves in the direction indicated by the arrows in Fig. 2 during the operation of theblower. This is caused by the engagement worm 51 on the rod 41 Revolving with the worm gear 50 is a cam plate 52 provided provided for therewith of a During worm gear 50 and cam 52 the rod 46 is held stationary in its raised position with the valves open by reason of the fact that the greater part of the edge of the cam is at a constant distance from, the center thereof.

After "the blower has been. operated fora sufficient length of time to insure the blowingout of all the fumes from the wardrobe, and the. substitution therefore-of air from the exterior, the worm gear and carn'come around to such a position as 'to permit the cam follower 54 -to drop into the notch 53,

and thus permit the valveirod 46 to descend and the valves to, close. will preferably extend to a chimney, ventilating shaft or the like in order that the fumes may. not be discharged into the room in which the wardrobe is located. If preferred, this pipe may beextended into a suitable device for absorbing the gases, such as a receptacle containing water, with the pipe so arranged as to discharge below the The outlet pipe 48 surface of the-waterand permitjthe fumes to pass up through the latter.

The shaft 5,0.on which the gcari5O and I cam 52 'aremounted extends in toward the center of the wardrobe and carries upon its inner end a cani56 which, when the'cam 52 has revolved to such a position that the cam" follower is about to fal'l'into' the notch 58, positionin which it is shown in Fig. 4, at which position"further movement' reaches the will'cause the cam 56 tovpass underlatch 35 and raise these-glue, thus permitting the plunger 20 to 'move out from under the latch and uhlocltthe door. In order that this unlocking movement may be effected quickly, the worm gear 50 and cam 52 are, as above stated, mount-allows upon the shaft 50 movement being imparted to the shaft from the worm gear through a pin 57 1 wl'uch projects from the side of the worm gear and engages the sideof an arm which is fast on the shaft 50 and carries a ball or other suitable weight 58. "hlVhen the 'sh'aft 50 and ball 58 have reached the position shown in Figs. 2 and hjfurther movement of these parts in the direction ,indicated b'ythe arrow in Fig. 2 will carry'the ball past a line extending vertically through thecenter thereof and the center of'the shaft; thus pernuttlng the weight to fallforward and come into enga ement with a second pin '59 which extends from the face 'of theworm gear. When the weight thusffansx forward it quiekly'carries the shaft around for a further short distance and-causes the cam 56fto pass underand raise thelateh 35, which ieleases the plunger. 20, latch again falling to the posltion shown inFig. Thefdoorls now 1L locked and. may be opened 'When thephingermoves outward after being re f leased by the lifting ofthe latch the spring 3% draws the piston QS'out'to the limit ofits movement, thus drawing a quantity ,of'liquid into the cylinder from the tank 275 Whenthe door is again closed therotation of the pressure bar 15 to the looking position brings the arm 22 into engagement with-the j plunger 20 and thrusts the same, inward. The engagement of the piston stem 3i with the inner end of the plunger causes the piston to be driven in, and the inward movement of the piston forces liquid from the cylinder, up through the outlet [29 of the pump in a small stream, which, issu ng from the upper end of'thepassage 29, impinges against the under side of a bell-shaped defleeting plate 59 which sprays the liquid and throws the same down pen an evaporating pad 60, which may be ceinposed'of felt or similar material, from WlllCll the ll'qLUQCl va device is inu leased from'the latch35.

or the veriinicidal liquid will be contained in the pump. The clothing or other articles having been hung or ot erwise placed in p0:

sition in the wardrobethe doorthereof will be closed.

To lock the door the handle 171 will be swung aroundto the position opposite that shown in Fig. 1. This movement causes'the arm 22 carried by the pressure bar to engage the knob 21 of the plunger 20, forcing the same inward. At

the pins 20 of the locking devices upon the door to be firmly seated against the cork strip 12 which extends around the doorway. Theinwalrd movement of the plunger 20 is transmitted to the piston 28 through the piston stem 31, and a certain quantity of the vermicic'lal liquidisforcedout of the pump cylinder Qtand sprayed upon the evaporating pad GOQVEVZLPOI'QHOH ofthis liquid chargesthe air within the wardrobe with the fumes of the liquid, u 'lnch'results in the killing of anymoths or other vermin which may have gained access tothe wardrobe whilethe door was open or been carried into the wardrobe upon the articles that were Some of v the substances I which may be used for this purpose mayno t'; befcapable of killi' ig, when vaporized, the

"When the wardrobe is to be opened this cannot be done until thefumes have first been expelled from the same.fln;order to open the Wardrobe the pressure bar will first be revolved and the devices at the ends thereof unlocked by throwing the handle,
