l This invention lrelates to atomizers of the character commonly used for the spraying of perfumes or other toilet liqulds, and has parthe pump type of atomizer.

The object of the invention is the provision of a simple, eiiicient and improved atomlzer of this character which is small in size to adapt it to be carried in a 1purse or vanity case and which may be tight y sealed against leakage of its liquid contents and have its pump locked in inoperative position by the movement of a single element. The invention is fully described in the following specification and while in its broader aspect it is capable of embodiment in numerous forms a preferred embodiment thereof is illustrated in the accompanying drawing, in which,-

Figure 1 is a top plan view of an atomizer embodyin the invention, with the parts in sealed an locked osition. Fig. 2 is a central vertical section o the atomizer taken on the line 2-2 in Fig. V1. Fig. 3 is a top plan view of the atomizer with the parts in usable position. Fig. 4 is a side elevation of the atomizer with a rtion in central vertical section and a part roken away and with the parts in the usable position shown in Fig. 3, and Fig. 5 is a cross section on therline 5-5 in Fig. 2.

Referring to the drawing, 1 designates the liquid receptacle of the atomizer which is small in size and preferabl of cylindrical form with its to open to a apt to be closed by a ra hea 2 threaded therein. This sprayea has a central vertically disposed opening'3 therethrough preferably of tapered form to adapt it to receive a conical type of plug valve 4, the lower end of `which has the tube 5 extending therefrom down into the rece tacle 1 tonear its bottom. The upper end ofpthe tube 5 communicates with a recess 6 in the valve 4.

The spray head 2 has a s ray discharge ich is adapted to communicate through a passage 8 Yin the head and a registering passage 9 in the valve the socket 6 when the valve member is in the usable position shown in Fig. 4. The head v2 also h tending crosswisethereof and opening at its to those generally known asas an a1r passage 10 e1:-y

outer end centrally in the bottom of the discharge orifice 7 and has its other end commumcating throu h a tube 11 with the pump member of the evice, as hereinafter described. When the valve 4 is in its open position, a passage 12 therethrough registers at its endswith the separated arts of the air passagel 10 and maintains suc passage open and when the valve is turned to its close position, the passage 12 is moved out of register with the air passage 10, thus effecting a closing of such passage. Nothing new in itself is claimed 'for this construction of atomizer.' y

The air pumping means for the atomizer comprises` a pump cylinder 13 in which a plunger 14 1s mounted for reciprocatory movements. This plun er hasl a stem 15 projecting upwardly thererom through the upper end of the cylinder to adapt the plunger to be-operated in one direction by the ressure thereon of the thumb of a hand ho ding the device. The plunger is actuated in the opposite direction by a coiled expansion spring 16 that is mounted in the bottom of the cy inderand bears upwardly against the plunger.

The air tube 11 extends from the atomizer head 2 down between the atomizer receptacle 1 and pump cylinder 13 and enters the pump cylinder at its lower end. In the present instance the tube 11 extends down through a hollow member 17 which is dis osed between the receptacle 1 and pump cylinder 13 and is recessed at its opposite sides to fit the two members 1 and 13 which are secured thereto.

The valve member 4 has an operating arm 18 projecting laterally from its upper end so as to adapt 1t to project over and enga e the top of the plunger stem 15 when in its depressed position to retain it in such position. is preferabl provided at its outer end with a ball mem er 19 which is ada ted to Seat in a recess`20 in the top of the p unger stem when in engagement therewith, thus tending to retain the ball and stem in engagement.

e arrangement of the passages 9 and 12 in the valve 4 is such that the are turned out of register with the spray liead passages 8 To facilitate such action, the arm 18 I the lower end and 10, respectively, locking engagement 15, as shown in Figs.

when the arm 18 is in with the plunger stem 1 and 2, and are in register with said spra head passages when the valve arm is turne to the open or operative osition shown in Figs. 3 an 4. The swinging movement of the valve arm 18 1s limited by a pin 21 rojecting from the valve at the outer end o the spray head 2 and coacting with o posite end walls of a recess 22 in the spray ead in which it works.

It is apparent that in the use of mivl improved atomizer, the operator first t rows the valve arm 18 to the right to release it from locking engxagement with the plunger stem 15 and to t row the plugx valve 4 into open relation with res ect to t e spray head passa 8 and 10. he operator may then operate the plunger to cause a discharge of air under pressure from the s ray head orifice which effects a drawing up o liquid from the receptacle through the tube 5, recess 6, an passa es 9 and 8, as well understood in the art. en the operator is through using the atomizer, he merely depresses the plunger to of its stroke and then swings the valve arm 18 to the left to effect a closing of the spray head passages and to place the ball 19 in locking engagement with the plung- I wish it understood that my invention is not limited to any specific construction, form or arrangement of the parts, as it is capable of numerous modifications and changes without departing from the spirit of the claims.
