SPR-AYER Application inea May i7,

This invention relates tornew and useful improvements in a sprayer.

The invention has for an object the provision of a device of the class mentioned l which is of simple durable'construction, de-

pendable in use and efficient in action, and which can be manufactured and sold at a reasonable cost.

It is conventional to make sprayers which consist of liquid containers and spraying means, but the spraying means on such containers are not capable of elhciently spraying downwards. Such spraying is very' desirable in many cases, particularly by persons engaged in dampening or wetting cloth operated upon a table in various industries. lt is very necessary that the spray be directed downwards upon the goods for the proper dampening. In many types of the present sprayer, when the discharge is directed downwards a stream of water is obtained instead of a spray. The reason for this is that the water reaches the air passages of the spraying means and is then discharged in a stream. It is another object of this invention to provide a sprayer which can spraydownwards and upon ceasing of thespraylng operation not to drip. It is proposed that the sprayer be so arranged that by siphonic action all of the liquid from the spraying nozzle would run back into the container. It is also proposed that the siphonic back flow be started by a natural swinging ofa portion of a tube projecting into the liquid 1n the container for the passage of the liquid to the spraying nozzle. e i

Another object of this invention is to provide a novel handle for the above sprayer.

For further comprehension of the invention, and of the objects and vadvantages thereof, reference will be had to the following description'and accompanying drawing, and to the appended claims in which the various novel features of the invention are more particularly set forth.

The sprayer consistslof a liquid container 10 for resting upon some support, spraying means 11 on said container and including a bent discharge nozzle `12 directed downwards 60 Y and a lateral discharge bulb 13, a lateral handle 14 projecting from said container 10 and extendingabove said bulb 13 vso that the bulb may be squeezed with ones four fingers and the 'container moved with the same hand, 55 and a supply tube lvextending from said container upwards to said nozzle 12 ,and including a lower section 15a movably supported so as to shake during moving of said container and' cause siphonic. iiow of the 7 liquid back into the container uponrelease of said bulb. f

The liquid container l0 shown onv the drawing is a vessel having a flat bottom 16 for resting upon a table or other support and formed with a neck 17 at its top. The main portion 18 of the vessel is large and located near the bottom so that it is stable when Aresting upon a flat surface. The neck 17 'terminates in a threaded portion for receiving a threaded hollow member 19 supporting the said discharge nozzle 12. The hollow member 19 is also formed with a downward extending beak 20' extendingv partially through the neck 17 of the container. A lateral branch 21 connects with the hollow member 19 and'is intended for receiving a flexible tube 22-connected with ysaid discharge bulb 13. The bulb 13 is of conventional design c and is providedwith a valve so as to be capable oftaking any air from the atmosphere and discharging the air through the tube 22 upon being alternately squeezed and released. The discharge nozzle 12 includes a removable tip 23 Yformed with a very fine aperture at itsV front constituting the spraying j opening. The hande 14 is made froin'sheet metal and is slightly curved so as to partially encircle the bulb 13;.v The front vvportion of the handle is flat and isadapted for vengaging upon the threaded portion of the hollow member 19. This member is formed with a liange 24 at the top of the threads so that the handle may be clamped upon the neck of the container. Necessarily the handle 14 is formed with an aperture 25 so as to be capable of being engagedupon the threads of the member 19. \j

The said supply tube 15 is a very thin tube and extends from within the container 10 completely through the lnozzle 12 and terminates but a very short distance to the rear of the aperture formed in the tip 23. lVhen the bulb 13 is squeezed, air is forced from the bulb into the hollow member 19 and'tlien along the discharge nozzle 12 so as to encircle the tube 15 and iinally at the free end of the tube causes suction which draws liquid from the container. The air also mixes with the liquid drawn from the container and forms a spray which is discharged through the tip. The movable lower section 15ay oi: the supply tube 15 is resiliently and flexibly held in place by a piece of adhesive tape 26. As clearly shown in Fig. 4, the section 15a is spaced slightly from the top portion of the tube and thetape 26 is turned several times around the adjacent ends of these sections so as to hold the sections together and allow the passage of liquid completely through the tube. The resiliency of Jthe tape is depended upon to produce the resilient hanging of the lower section ot the tube. lVhile adhesive tape has been called for accomplishing the resilient connection with the lower section of the tube, this is not intended as a limitation since other resilient connections may easily be substituted. The lower section l5a is bent so as to terminate in the vicinity of the side of the container 10. 1t is calculated that when thel container is moved by the handle 14 the section 15a will freely swing and iii' its end is arranged close to the inner side of they container 10 will strike against the container and produce shock which will cause the siphonic back low of the liquid into the container when discharge ceases.

The operation of the sprayer may be traced by first assuming it to be at rest upon a table and assuming an operator working upon cloth or other material on 'the table which periodically must be sprayed.' l/Vhe-n occassion arises, the operator may lift the spray by simultaneously grabbing the handle 14 and the bulb with one hand. This allows t-he operators other hand to be free so as to smooth out the cloth or perform any other operation. Upon squeezing ofthe bulb 13 a tine spray is discharged, and this spray is discharging downwards without the necessity y of tilting thevspray, since the dischargenozthe lateral branch 21 and be discharged in a stream instead of a spray.

Upon close examination of the bent nozzle 12 it will be noticed that there is a high point, and a lead from the container to this high point, and a discharge from this high point to lthe atmosphere. Normally during the handling of the'container, capillary action is depended upon to hold the liquid within the tube 15 extending through the bent portion of the nozzle 12, but when the container isl placed to rest upon a support shock is produced by the swinging of the tube section 15 which breaks thetcapillary action so that the Y portionof the liquid would split at the high point if it were not 'for siphonic action, and a portion would discharge or drip from the tip 23. The liquid due to `siphonic action will flow back into the container. It shock were not produced'when the container was placed to rest upon the support the liquid would remain within the tube and dripping wouldV take place. The end of the section 15a is depended upon to strike the inside of the container and produce necessary shock to break the capillary action while back flow takes place.

, The edges of the front portion of the handle 14are bent downwards as indicated by numeral 14EL and at the sides connect with bent around sides 14b of the central portion of the handle. The flexible tube 22 extends from said lateral branch 21 through an aperture 14c kin the central portion of the handle and connects with said bulb 13 which is located on the bottom of the rear portion of the handle. Itis this rear portion of the handle which is slightly curved for fitting against the bulb, and also for fitting into the palm of Vones hand so that the bulb may be squeezed with ones thumb, orones four tingers, or thumb and four fingers combined.

While I have illustrated and described my invention with somedegree of particularity, I realize that in practice various alterations therein may be made. lI therefore reserve the right and privilege of changing the form of the details of construction or otherwise altering the-arrangement of the correlated parts without departing from the spirit or the scope of the appended claims. i
