Our invention relates to improvements in dry vapor sprays, and it consists in the combinations, constructions, and arrangements herein described and claimed.

An object of our invention is to provide a dry vapor spray which may be operatively connected with a moving element such as a door, whereby the device may be positively and automatically operated as when opening and closing the door.

A further object of our invention is to provide a device of the type described in which novel means is employed whereby a dry insecticide or deodorant may be employed, and in which novel means is used for forcing vapor from the device.

A further object is to provide a device of the type described which is ornamental in appearance, simple in construction, and in which means is provided whereby insects such as moths and the like'may be effectively controlled.

Other objects and advantages will appear therewith. In Figures 1 and 2 we have,

shown a bracket 3 as being mounted upon the casing 1 through the medium of screws 4.

The bracket is provided with a. plurality of openings through which supporting rods 5 project, whereby the rods ma be rigidly asno sembled in connection "wit the bracket through the medium of nuts 6. The op 0- site ends of the rods are threaded and disposed within threaded openings in an end plate 7. The latter closes one end of a casilfg C8 8 which is provided with a closure 9 having a central opening 10.

A perforated member 11 is secured to the closure 9 and is provided with a cap 12.1m-

ing perforations 13 therein. The member 11 provides a receptacle for the insecticide as will be explained hereinafter. In referring to Ifigure 2 it will be noted that a piston l i tomatically operated, and a device whereby a room and its contents may be efiectively conditioned to prevent insects such as moths andthe like. The device also provides a convenient deodorizing mechanism.

In Figures 6 and 7 we have shown a slightly difierent form of our device in which a cylinder 21 is connected with a bracket 22 having pivotal action upon a supporting bracket 23 through the medium of a bolt or rivet 24. The supporting bracket is mounted upon a frame or casing 25 having a coo rating moving element such as a door 26. he cylinder 21 is provided with a piston 27 having a piston rod 28 passing through a closure plug 29. The plug is securely fastened to the end of the cyhnder 21 and is provided with a plurality of openings through which bolts or screws 30 ma be passed for securing the plug to the brac et 22. One end of the casing is'provided with a multiplicity of perforations 31. This end of the casing is provided with a closure 32 having perforations 33. The casing is provided with a partition 34 having a central opening 35. The outer end of the piston rod.28 is operatively connected with a bracket 36 which is carried by the door 26.

- 7, that during the opening and closing of the door 26, the cylinder 21 will be caused to oscillate a certain distance. In this form of our device we have shown the insecticide as simulating sticks 37 which may be arranged within the perforated chamber of the cyl-.

Figures 8 and 9 show a modified form of bracket which may be employed for securing our device upon its supporting structure. Figure 8 discloses a bracket 38 having suction pads 29 secured thereto. In Figure 9 We have shown a slightly difierent form of our bracket which is also provided with suction pads as indicated at 40.

In actual use we apply a certain amount of lue upon-the suction face of the pads wherey the latter may be firmly secured upon a.

supporting structure. This feature eliminates the necessity for using bolts or screws in connection with finished woodwork. Ordinarlly, however, the devices are permanently mounted and are in themselves ornamental which, of' course, permits screws and the like to be employed.

We claim:

1. A device of the type described adapted to be operated by a swinging door and comprising cylindrical means carried by a stationary supporting structure, a piston means disposed within the same and passing to the exterior thereof, a moving element, connecting means secured to said moving elements Lemmas and located between the latter and said piston means whereby the piston is actuated when the moving element is moved, said cylindrical means being provided with an insecticide-containing chamber having an opening ,therein, and partition means disposed between the insecticide-containing chamber and said piston means and having an opening therein.

2. A device adapted to be operated by a swinging door ofthe type described comprising a cylinderprovided with a plurality of supporting rods fixed to a supporting stationary structure, a piston disposed within said cylinder, a piston rod connected .with the piston and extending to the exterior of the cylinder, a sliding block guided by said rods and connected with the piston rod, a moving element, and an arm secured to said moving element and connecting the latter with said sliding block.

3. A device adapted to be operated by a swinging door of the type described comprising a cylinder provided with a plurality of supporting rodsfixed to a supporting stationary structure, a piston disposed within said'cylinder, a piston rod connected with the piston and extending to the exterior of the cylinder, a sliding block guided b said rods and connected with the piston ro a moving element, an arm secured to said moving element and connecting the latter with said sliding block, and a perforated insecticidecontaining chamber associated with said cylinder.

4;. A device adapted to be operated by a swinging door of the type described comprising a cylinder provided with a plurality of supporting rods fixed to a supporting stationar structure, a piston disposed within said cy 'nder, a. piston rod connected with the piston and extending to the exterior of the cylinder, a sliding block guided by said rods and connected with the iston rod, a moving element, an arm secured to said moving element and connectin the latter with said sliding block, a per orated insecticide-com taining chamber associated with said cy]in der, and a partition disposed between the insecticide-containing chamber and said piston and having an opening therein.

5. A device adapted to be operated by a swingin door of the type described comprising a cylinder provided with a plurality of supporting rods fixed to a supporting stationary structure, a piston disposed within said cylinder, a piston rod connected with the sliding block, a perforatedinsecticide-containing chamber associated with said cylinder, a partition disposed between the insecti- EUGENE GOHN.
