To all whom it may concern:

Be it. known thatI, ARNOLD MoLLnnrrAUnR, a citizen of the United States, residing at New York, in the county of New York and State of New York, have-invented certain new. and useful Improvements in Oil Dispensing Devices, of which the following is a full, clear, and exact description, such as will enable Others skilled in-the art to which it appertains to make anduse thesame.

This invent on relates to apparatus for dispensing liquids, and wlth respect to- 1ts more specific features to apparatus ofthe character described for spraying or atomizing the materialto be dispensed. 7

One of the objects of the invention is the provision of a practical device of the character referredto wherewith liquid, and especially oil, may be atomized and sprayed indesired directions and places.

Another object of the invention is the provision of; a simple andconvenient device for- The invention accordingly consists in thefeatures of construction, combinations of. elements and arrangement of parts which will be exemplified in the construction hereinafter set forth, and the scope of the application of which. will be indicated: in the following claims.

In the accompanying drawings forming part of this specification and wherein similar reference characters refer to similar parts throughout/the several: views,

Figure 1- represents a side elevation of. an

embodiment of the invention, partly in section, for the better disclosure of interior parts; i

Fig. 2 is a. plan view of the device, with the blower removed;

Fig. 3 is adetail sectional elevationof a portion ofthe device;

Fig. 4 isa verticalsection of: a portion of' the device taken through the blower; and

Fig. 5ishows a modifiediform of: blower.

The numeral 1 indicates a reservoir or container for the material to be dispensed, andasthe invention is probably best manifested in connection with liquids-such"as'oil, it will be disclosed in connection with such materialblfipping into the liquid in the container 1* is a conduit 2 having a delivery opening, or nozzle 3. Projecting from the outside of the upper wall, or face, of the container is a hollow sheet metal neck, 4, through which SELlCl COI1ClL1lt 2 projects, said neck being preferably screw-threaded for th'e'reception of' a closing capf5, which is screw-threaded to cooperate with the threads onthe neck 4, and is provided with a suitablepacking, as a felt filling, washeror disk 6, which latter prevents leak to the outside from the nozzle 3 when the, cap is screwed on the neck, and also covers certain openings 23, hereinafter mentionedi The receptacle is preferably closedsave for the neck d and the openingsit contains. Detachably connected to the upper wall of'the container l is a blower, by means of which a. jet of air-may be discharged adjacent oracross-the opening or nozzle 3, so as to pro d'uceadepression in pressure at the nozzle, thereby resulting in the flow of oil through the conduit 2 andout of the nozzle 3, the air jet also serving to break up and thus atomize or spray the oil emitted from the nozzle. In the present embodiment the blower comprises a cylinder 7, within whichis a. reciprocatoryvpiston Shaving a handle 9 wherewith the piston may be reciprocated. The head 10 of the cylinder adjacent the conduit 2 has a small opening'll' disposed to direct the jetof air adjacent or across the nozzle 3, and a flexible stop, embodied in a fish-gut cord 12, is connected to the cylinder andto the piston tolimit the outward stroke offthe piston, and thereby restrain complete withdrawal of the piston from the cylinder. on said" stroke. The inward stroke of the piston may be limited by a] shoulder 13 thereon adjacent the handle 9. In the preferred embodiment the piston. comprises a cup ofleatherll on the end of a wooden plunger 1 5,which latter is integral with the handle 9 and; in transverse dimension, completely fills the blower cylinder. The cup of leather is securedon the front face of; the plunger by a screw-eye16 and washer 17, and the flexible stop 12 maybe connected to V the screw-eye 16 and to an eye or hook 1-8 soldered or otherwise made fast to the re movable head 10 of the cylinder.

The most efficient operation of the device is manifested when the conduit 2 is quite small in diameter so that the liquid to be dispensed naturally fills a substantial portion of the conduit above the level of the liquid in the container. Under such circumstances a jet of relatively light force is suflicient to cause the'emission of the liquid from the nozzle. The operative effect of a jet of normal force on the nozzle may be varied by adjusting the discharge opening 11 relative to said nozzle, the operative effect being less when the opening 11 is relatively remote from the nozzle and increasing as the opening 11 is placed nearer and nearer thereto. To provide for varying the operative effect the blower is mounted on the container, so that it may be adjusted toward and from the nozzle, and a construction is preferably employed which, not only permits of such adjustment, but also provides for thedetachable connection of the blower and container. The upper surface of the container is provided with a slide way which may be. embodied in a plate 19 soldered to 7 said upper surface and having inturned flanges 20 providing undercut grooves for the reception of a similar but oppositely flanged plate 21 fastened to the cylinder of the blower. By this construction it will be perceived that the blower may be adjusted toward and from the nozzle 3 by merely sliding the same inwardly or outwardly relative to the plate 19, the flanges of the

plates

19 and 21 cooperating in a resilient manner, being of sheet metal, to frictionally clamp, or retain the blower in any desired position of adjustment. At the same time it will be perceived that the plate 21 may be shifted outwardly so as to completely escape the end of the plate 19, and thus the blower may be detachedfrom the container. 7

The utilization of a conduit tube 2 of relatively small cross section as before described causes the oil to naturally assume a position in said. conduit above the level of the main body of liquid in the container, due to capillary attraction, and a slight reduction in the volume of the container, as by a bending of the lateral walls inwardly will or made rigid relative to each other. Preferably also the horizontal longitudinal axis of the container is much longer than the transverse axis, so that the container is of an elongated character horizontally and may be readily inserted in corners and places otherwise not readily accessible.

The nozzle of the conduit 2 is disposed adjacent one end of the container and the blower is adjustable toward and from said nozzle longitudinally of the container, and preferably the diameter of the cylinder of the blower is not greater than the transverse horizontal axis of the container, so that the blower lies on the container between the planes of its lateral walls, as does the nozzle 3, the whole forming a structure which is very convenient to handle and which may be efiiciently packed with others into a modi cum of space. The container may be filled through a small opening in its lateral wall which is afterward sealed with a drop of solder, or it may be filled in any other suitable manner. I

Resulting from the operation of the device, or by reason of leakage, oil is not infrequently retained at the nozzle 3, which is beyond the neck 4, and flows down the out side of the tube of the conduit 2. Successive portions of such unused oil would soon contaminate the exterior of the apparatus rendering it greasy to the feel, slippery, and otherwise uncomfortable to use To dispose of this oil the upper face of the neck 4 is depressed, providing a cup 22 for the reception of such oil. Furthermore the cup is provided with openings 23 communicating with the interior of the neck 4 whereby the oil received in the cup 22 may flow into the neck 4, and thence into the main interior portion of the container through the openings 24 in the upper face of the container within the neck 4, which latter openings in connection with the openings 23 also serve for the entry of air into the space above the liquid in the container. passes through the bottom of the cup 22 and the upper face of the container, and is secured thereto and braced in position by said cup and face. i

To operate the device the container is filled withoil, the screw cap 5 is removed, and the piston is reciprocated to cause successive jets of air across the nozzle 3. The reduction of pressure at the nozzle will cause the oil to rise and be emitted from the nozzle, whereupon the air jet will spray or atomize the emitted oil. In operating, the container is grasped in one hand and the blower operated by the other, and even should the operator involuntarily grip the container tighter than may be necessary, the lateral walls of the container will not move inward so as to cause the oil to be thereby ejected from the nozzle. Any drip or un- The conduit 2.

utilized oil will be caught by the cup 22, andwill eventually find its way back to the main reservoir through the

openings

23 and 24.

Instead of using the cord 12 to limit the outward movement of the piston, the wooden plunger 15 may be reduced in diameter for the greater portion of its length providing a shoulder 30 cooperating with an outer head or shoulder 31 on the cylinder, this outer end of the cylinder being spun or otherwise folded inward to provide the shoulder or head 31, as shown in Fig. 5.

Thus by the above described construction are accomplished, among others, all the objects hereinbefore referred to.

As many changes could be made in the above construction and many apparently widely different embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

It is also to be understood that the language used in the following claims is intended to cover all of the generic and specific features of the invention herein described, and all statements of the scope of the invention, which, as a matter of language, might be said to fall therebetween.
