JOHN S. MAOMULLEN AND MORTON" L. MGREYNOLDS, OF SAN FRANCISCO, CALIFORNIA.

DISPENSING DEVICE.

Application filed April 30, 192 5.

To all whom it may concern:-

Be it known that we, JOH S. MACMUL- LEN and- MORTON L. MoRnYNoLDs, citizens of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented new and useful Improvements in Dispensing Devices, of which the following is a specification.

This invention relates to improvements in dispensing devices and has particular reference to a device which may be employed in public buildings, such as theatres and the like for. the purpose of dispensing a perfume or deodorant or like fluid.

The principal object of this invention is to produce a simple device which may be attached adjacent a door so that the opening and closing of the door will cause the fluid to be dispensed.

.A still further object of this invention is to produce a device of this character which is extremely simple and therefore cheap to manufacture.

Another object of this invention is to produce ajdevice which will operate when the door moves in either direction. 1

An additional object is to produce a device of this character which is neat in appearance and one which will not mar the beautyof the room in which it is placed.

Other objects and advantages will be apparent during the course of the following description. v v

In the accompanying drawings forming a part of this specification, and in which like numerals are employed to designate like parts throughout the same, I Y

. port 19 closed Serial No. 27,002.

Figure 9 is a fragmentary detail view showing the nozzle of our device.

It is well known that after a number of people'have been present in an amusement house for some time that the air often becomes stale, Furthermore, there is generally present in toilets and like places a certain amount. of foul air. These inconveniences have heretofore been overcome by sprinkling or spraying deodorantsin the referred to places.

We have. found that by placing a device of thisicharacter near an entrance door to a theatre or toilet that every time the door is opened the deodorant will be dispensed through the atomizing nozzle and that the actual draft of the door, as well as the circulation of air caused by the person passing through the door will more evenly distribute the deodorant than it is possible to distribute with the ,old hand pump arrangement. v

In the accompanying drawings wherein for'the purpose of illustration is shown a preferred embodiment ofour invention, the numeral 5 designates a casing adapted to be attached to the wall as by brackets 6. Within this casing is positioned a receptacle 7 which forms a tank within which the deodorant is placed. This tank has secured thereto and extending to the bottom thereof, a tube 8, which tube extends forwardly and has a depressed portion 9. This depressed portion forms a trap adjacent the end thereof, which end is shown at 11 and terminates in a, nozzle 12 supported by a bracket 13 upon the casing 5.

, This nozzle has secured thereto a tube 14 to which is attached a rubber tube 16. To the" opposite end of this tube is secured a tube 17 which enters one side of a bellows designated as a whole by the numeral 18. This bellows may be constructed in any convenient manner and has'the usual intake by a flap valve 21.

A" shaft 22 extends across the casing 5 and serves to support the bellows 18 through hinged members 23 and 24. A coiled spring 26 encircles the shaft 22 and has its opposite ends contacting the bellows as shown at 27 and 28, the result being that this spring normally tends to keep these portions of the bellows in contact with each other.

Operating arms 29 and 31 are connected to the opposite side of the bellows and extend below the casing 32 and 33, respectively. A bumper pad 34 is positioned so as to lie between the ends of the levers 29 and 31 as best shown in Figures 1, 6 and 7 The lower extremities of these levers are bent at right angles so as to pivotally support tips 36 and 37 which are pivoted at 38 and 39, respectively. Each of these tips is provided with a lug 41 which contacts a pin 42, the result being that those tips can swing in one direction only.

A pair of links 43 and 44 are pivoted together as shown at 46 and have their free ends pivoted to the pivot points 38 and 39. The link 43 is provided with a cam end 47 while the link 44 is provided with a spring portion 48.

A yoke 49 is adapted to slide along the link 44 and has a wedge 51 adapted to be interposed between the end of the yoke and the spring 48.

A set screw 52 is also carried by the yoke,

the purpose of which yoke is to adjust the tension or flexibility of the spring 48 when contacted by the cam 47, as best shown in Figure 8. Attached to the door indicated by the numeral 53 is a bracket 54 having a roller 56. The result of this construction is that when our device is attached to the side of a door as shown in Figure 5, the openingof the door will cause the roller 56 to come into contact with the tip 36 and to contact the tip 37 as this tip cannot revolve upon its pivot 39 due to the pin 42, the result will be that the roller will push against this tip and move the lever 31 in the direction of the left hand arrow of F igure 1.

This will open the bellows 18, thus drawing air through the port 19 past the flap valve 21.. As soon as the roller 56 has left its contact with the tip 37 by passing beyond its arc of movement the spring 26 will commence to function and tend to move the arm 31 back to its normal position. This will cause air confined within the bellows to be expelled through the tubes 17, 16 and 14 and from the nozzle 12. This will cause the deodorant to be drawn from the receptacle 7 through the tube 8 and due to the injector action a thin stream will be blown out of the nozzle 12. In order to prevent too rapid a closing of the bellows the links 43 and 44 will function and as the spring 48 contacts the cam 47 greater resistance will be offered. This resistancewill gradually drop to zero as the lever 29 moves to its normal position.

hen the door moves back, the same action will take place with the exception that the tip 37 will be passed and the tip 5, through openingsthe lever 29 and cause the the same function as above 36 connected to same to perform described. 7

It is to be understood that the form of our invention herewith shown and described is tobe taken as a preferred example of the same, and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

Having thus described our invention, we claim 1.. In a device of the character described, a receptacle, a tube extending into said re ceptacle and adapted to conduct a fluid therefrom, a bellows positioned adjacent said receptacle, a nozzle secured to said tube, means for conducting air from said bellows to said nozzle, a pair of levers connected to opposite sides of said bellows, and means for moving either of said levers for the purpose of causing said bellows to force air therefrom.

2. In a device of the character described, a receptacle adapted to contain a fluid, a tube extending into said receptacle, said tube having a nozzle formed at its opposite end, a bellows positioned adjacent said receptacle, a spring secured to the opposite sides of said bellows and adapted to normally maintain said bellows in closed position, means for conducting said air from said bellows to said nozzle, a lever connected to each side of said bellows, and means for operating said levers for the purpose of expanding said bellows against the tension of said spring.

3. In a device of the character described, a receptacle adapted to contain a fluid, a tube extending into said receptacle, said tube having a nozzle formed at its opposite end, a bellows positioned adjacent said receptacle, a spring secured to the opposite sides of said bellows and adapted to normally maintain said bellows in closed position, means. for conducting air from said bellows to said nozzle, a lever connected to each side of said bellows, and means for operating said levers for the purpose of expanding said bellows against the tension of said spring, a pivoted tip secured to the lower extremity of each of said levers,

said tip being movable in one direction only,

and retarding means positioned between the lower extremities of said levers, for the purpose specified. 4 V

In testimony whereof We affix our signatures.
