1 Claim.

An object of my invention is to provide a spray oller which is simple, durable and comparatively inexpensive to manufacture.

AV further object is to provide a spray oller of -compact design comprising a container for oil or the like, and a fitting associated therewith having a discharge nozzle' for sprayed oil, an intake valve for compressed air for placing the contents of the container under pressure, an intake tube .depending within the container, and a control valve for the flow of oil, the container having a supporting handle adjacent to which the control element of a control valve is located for convenience in controlling the flow oi' oil from the l5 container to the nozzle.

A still further object is to provide a nozzle construction which is adjustable for producing either a needle spray or a wide spiral spray, the nozzle being also adjustable to intermediate positions for thereby adjusting the spread of the spiral spray.

With these and other objects in view, my in-4 vention consists in the construction, arrangement and combination of the various parts of the device, whereby the objects contemplated `are attained, as hereinafter more fully set forth. pointed out in my claim, and illustrated in the accompanying drawing, in which:

Figure 1 is a side elevation of my spray oller I) with the container shown in section.

i Figure 2 is an enlarged, vertical, sectional view through the tting at the top of the container and the nozzle connected therewith.

Figure 3 is a sectional view on line 3-3 of Figure 2.

Figure 4 is a sectional view of the nozzle on a still larger scale showing the parts in a different position than Figure 2.

Figure 5 is an enlarged perspective view of a `4() bushing used in the nozzlew Figure 6 is a sectional view similar to the left end1 of Figure 2, showing afmodltied construction; an

Figure 'I is an eniargedsectional view on the line 'I--i of Figure 6. 1

On the accompanying drawing Ihave used the numeral I0 to indicate `a container for oil or the like I2. A handlel I4-is welded to the container I0 for the purpose of conveniently supporting the spray oller when it is in use.

Soldered or brazed inwthe top of the container IIJ is a threaded bushing Ii. A nozzle fitting, generally referred to as A, is threaded in the bushing I6.- The fitting A comprises a body portion I8, a nozzle sleeve 2li having a second nozzle f passageway 46.

sleeve 22 threaded thereon, a control valve body 24, and an intake valve 26-jfor compressed air. The sleeves .20, 24";and ZBare screw threaded into 'the body member I8.'

The fitting 26 includes an ordinary tire valve l 28 and a dust cap. 30. The dust cap can be removed and a tirev chuck engaged with the tting 26 to introduce compressed air into the container i0 through a passageway 32, which, as shown in Figure 3, is independent of lthe bore 34 of the member I8. The bore 34 has communicating therewith an intake pipe 36 depending within the container I0 and terminating in a` strainer or screen 38 adjacent the bottom of the container.

The nozzle sleeve 22 is provided` with a discharge orifice 4U and is packed relative to the sleeve 20 by a spring urged packing 42. Within the sleeve22 I provide a bushing `44 having an oil passageway 46 and a spiral groove 48 in the periphery of the bushing and by-passing the 2U A point kelement 50 is mounted in the outer end of the sleeve 2li and is adapted for seating against the edge of the passageway tt, as shown in Figure 4. The point element is suitably per te forated to permit the passage of oil therethrough when the point element is so seated.

For coactionywith the inner end of the sleeve 20 I provide a valve member .'52` normally seated by a spring M. This valve may be unseated by a lever 56 which, when pushed downwardly as indicated by the arrow a in Figure i, retracts a stem 58 connected with the valve member W. Suitable packing isprovided yat 6U to prevent leakage of oil around the stem iti. um

In Figures 6 andi I `show a modified construction which eliminates the necessity of providing the bushing it with its spiral groove 48.

In these figures a fitting A ls illustrated, having a sleeve 20a terminating in a pointed or iii tapered element 50a.` A groove. 48a is formed in the inclined portionoi the pointed element 50a, the cross section ci the groove being shown in Figure 7.

il. tapered here lita ci a head ma is machined M3 at the same angle as the pointed element 50a, so that when. therhead iiia is screwed onto the sleeve 20a as far asit will go, the surfaces 46a and Sila seat relative to each other. ,m

Practical operation The fittings A` or A can be removed for partially llingth'e-Ycontainer I0 with oil. The fittingmaythenfbe replaced and air introduced thrughjtheiitting 26, thus placing the contents 55 of the container under pressure. Subsequently when the valve 52 is opened, with the parts in the position of Figures 2 or 6, a needle spraywill result. The passageway 46 in Figure 2, or the space between the tapered point 50a and the bore 46a, offer less resistance to the owpf oil than the annular grooves I8 or 48a, and consequently the oil flows around the

points

50 or 50a and then through the nozzle openings 40 or 40a, resulting in a needle spray b or b', as indicated in Figures 2 and 6.

When the point 50 is seated, as in Figure 4, however, the oil must travel through the spiral groove 48 and in so doing rotation is imparted to it and centrifugal force causes the spray to corne out in a cone shape, as indicated at c. By

' partially closing the point element against the Some changes may be made in the construe--v tion and arrangement of the parts of my device without departing from the real spirit and purpose of my invention and it is my intention to cover by my claim any modied forms of structure or use of mechanical equivalents which may be reasonably included within their scope.

I claim as my invention:

In combination with a container for oil or the like, a fitting connected with the top thereof and comprising the following elements: a nozzle projecting horizontally in one direction therefrom, a control valve for controlling the flow of :fluid from said container to said nozzle and having a stem, an operating lever pivoted to said control valve stem, projecting horizontally in the opposite direction from said fitting and having a projection engaging the end of the control valve, an intake pipe connected with the bottom of said iitting, depending within said container and terminating adjacent the bottom thereof and an intake check valve at the top of said fitting for receiving compressed air and discharging it into said container, and a handle on said container so located withrespect to said lever that said lever may be readily swung about its pivotal connection with the thumb when said container is being carried by means of said handle whereupon said projection engages said control valve and effects pulling of said control valve stem outwardly relative thereto and thereby opening of said control valve.
