T all whom t4 ina/y concern:

Be it known that I, STEPHEN KE'rTLn, a citi- Zen of the United States of America,'and a resident of Chicago, in the county of ook and State of Illinois,.have invented certain new and useful Improvements in Spraying' or Atomizing Apparatus, of which the following is a specification.

The present .invention relates to that class of hand appliances in which a blast of air is employed for spraying, atomizing, and pufiing liquid or pulverulent materials for personal application, fumigation, and other similar pur poses, and has for its object to provide a simple, durable, and eiiicientstructural arrangement and combination of parts whereby the atomizing, spraying, or puiiing operations are effected in a uniform and eiiicient manner, all as will 4hereinafter more fully appear, and be particularly pointed out in the claims.

In the accompanying drawings, ,illustrative of the present invention, Figure 1 is a vertical sectional elevation'of the present appliance, illustrating the arrangement of the same 4 in the simpler form of a puffing apparatus for pulverulent material, such as insect-powder. Fig. 2 is a similar View of a more complex form of the present apparatus adapted for atomizing or spraying liquid material, such as disinfectants, cc. Fig. 3 is anfenlarged detail section'of the jet-nozzle of the apparatusl illustrated in FigQ. Fig. 4 is afdetached perspective View of the spring by which a return movement is imparted to the flexible diaphragm of the air blower or mover. i

Similar numerals of reference indicate like partsin the several views. 'i

Referring to the drawings, 1 represents a casing having closed side `and bottomy and an open-topped rim 2 for the attachment of the bellows-diaphragme hereinafter described.

3 is a central tubular neck on the bottom of the casing 1, adapted forthe attachment of a closing-cap a or of the attachingneck 5 of a iiuida'eceptacle in the varied uses of the apparatus, as hereinafter'more particularly described. i

G is a lateral tubular neck at one side of the (No model.)

casing 1, adapted for the attachment of a clos'- ing-plug 7 or of an outlet-nozzle 8 in the like varied uses of the apparatus, as hereinafter more fully set forth.v

9 is a check-valve of any usual form controlling an air-inlet opening 10, preferably arranged in the bottom wallof the casingl, as shown. l

11 is a check-valve arranged in a removableseat 12, which is adapted for insertion in the aforesaid tubular neck 3 of the casing l when the same is used in connection with a separate fluid-containingvessel for atomizing and spraying purposes. Such valve opens downwardly from its scat `and is adapted to prevent any reflux of air through the neck 3 in the operation of the apparatus..

13 -is a collar fitting the upper end of the neck 3 and the casing .1. i

14 and 15 are inner and outer flexible diaphragme, of leather or other equivalent mate rial and preferably in the drawings andhaving their margins secured to the open rim 2 of the casing 1, as

.shown in Figs. 1 and 2.

16 is a spring cap-plate havingbearing beneath the inner diaphragm 14 and forming an abutment'for the Lipper end of the coiled spring hereinafter'described. y

-17 is an intermediate bearing-plate arranged ona median line of the apparatus and between ythe inner and outer diaphragms 14 and 15.

18 is an outer bearing-plate secured tothe upper surface of the outer diaphragm and which in ordinary cases is secured to such diaphragm by a fastening means which extends from the plate 18 t5 the intermediate plate 17. In some cases, however, a cementing of the plates 18 and 17 to the outer diaphragm 15 may be depended upon as a connecting means between the parts.. Theouter bearing-plate 18 is extended mainly for the attachment of the actuating means 19, by which the diaphragme of the dome shape .shown Solv are repeatedly depressed in the actual use of the apparatus, and such actuating means may be'of any usualand' suitable form and either a thumb-ring 20, secured` directlyto the plate'` 18, as illustrated in Fig. l, or a headed pushrod 21, as shown in Fig. 2, and where certain uses may so indicate a lever mechanism may be employed to actuate the said push-rod.

22 is an inclosing housing for the diaphragms, having a depending skirt which tits Figs. 2 and 3 of the drawings, will consist oi .I interior ot' the receptacle 27 at a point above a smaller liquid-conducting tube33,which at `casing l, as shown.

said spring the same is composed of two inner `receptacle heretofore referred to and which `bottom neck 3 of the air-blast casing 1 and l l l l the periphery of the main casing l, as shown in Fig. 2, and is secured theretoby screws 3. i 24 represents holding handles orgrips on 1 the 'upper part of the housing 22 for convenience in holding the apparatus during themal nipulation of the same. l 25 is a spiral spring which has the form of' l an inverted cone, with its upper end bearing against the under side ot the-cap-plate 16, aforesaid, while its lower end surrounds the collar v13 and bears upon the bottom of the In a preferred form ot coils formed from a single piece of wire and united together at top by a transverse integral member 26, as shown in Fig. 4. f

27 is the separate fluid-containing vessel or may be of any usual and suitable shape and formed of glass, porcelain, metal, or other uncorrodable material. Such receptacle is provided with a filling-orifice 28, closed by a suitable plug 29, with the before-mentioned attaching-neck at top for engagement with the with an outlet-nozzle 30, of any usual construction, and through which the liquid contents of said receptacle is discharged in a sprayed or atomized condition for a wide num ber of uses, among which may be mentioned the spraying the person with perfumes or medicants, washing Wounds, applying liquid insect-extermivnators, &c. Such outlet-nozzle 30, however, in the preferred construction, as shown in an external air-tube' 3l, connect-ing with the the nbrmal liquid level in the same and provided at its discharge end with a conc-shaped jet-head 32.` Vithin said air-tube is arranged the end adjacent td the 4outlet of jet-head 32 is flattened to form a restricted outlet 34x, as shown in Fig. 3, while the other end of said' tube extends to near the bottom of the receptacle 27 as shown in Fic'. 2.

In the use of the present invention, with the parts arranged as shown in Fig. 1, with such arrangement adapted for use in putting Ainsect-eXterminating powders and' the like the tubular neck 3 is closed by the cap 4, the valve 1l and its seat 12 having been removed and the outlet-nozzle 8 attached to the tubular neck 6. As so arranged the powder to bc pulled is placed within the interior ot the casing l, preferably through the tubular neck 3. Then by an alternate depression and release ofthe diaphragms aforesaid by the hand or thumb 'of the operator the powder will be puffed through the nozzle 8 in a very perfect manner.

In the use o'f the present invention with an arrangement of parts as shown in Fig. 2 and adapted for use in -spraying or atomizing liquid substances the nozzle 8 is removed and the lateral tubular neck 6 closed by the lillin'gplug 7. The cap 7 isalso removed from the tubular neck` 3 and the valve ilv and valvescat 12 inserted in place, atter which the receptacle 27 is screwed into place upon the neck 3. By a manipulation in the diaphragme in 'the manner above mentioned a constant pressure of air is created within the receptacle l27 to discharge the contents of same a gradual and uniform manner and which discharge as it passes through the jet-head 32 is atomized in manner usual to such type of ietheads.

Having thus full y described my said invention, what I cla-ini as ne\ and desire to secure by Letters Patent, is---- l. In an atomizing or spraying apparatus ot' the character herein described, the combination of acasing having an open rim at top, inner and outer flexible diaphragme, marginally secured te said rim and adapted tot manual actuation, a valved air-inlet to said casing,

3. In an atomizing or spraying apparatus of the character herein described, the combination of a'casing having an open rim at top, inner and outer flexible diaphragms, marginally secured to said rim and adapted for manual actuation, a valved air-inlet to said casing, an outlet-passage from said casing provided with a removable valve-seat and valve, a lig uid-receptacle connected with said outlet-pas'- sage, and a discharge-nozzle on said receptacle, substantially as set'torth.v
