SPRAY DEVICE Filed Nov. 15. 1944 INVENTOR. C czr'j :Q I. @1117 5' BY- [Z Patented Mar. 11, 1947 SPRAY DEVICE Carl A. Stine, Van Nuys, Calif., assignor to Turco Products, Inc., Los Angeles, Calif., a corporation of California Application November 13, 1944, Serial No. 563,176

My present invention has to do with blast or spray nozzles and has for an object the provision of a nozzle which accomplishes controlled automatic oscillation or vibration of the discharge element in a manner to achieve a blast or spray pattern of considerable and controlled size.

Another object is the provision of a spray or blast nozzle which utilizes the action and pressure of the discharged fluid to play the nozzle about a limited field of oscillation.

It is also an object to provide, in combination with a flexible spray hose, a guard for controlling the oscillation of the discharge end thereof resulting from the action of discharged fluid.

Still further advantages of my invention will become apparent from the following detailed eX- planation of one embodiment which I have chosen for explanatory purposes, for which purpose I shall refer to the accompanying drawings, in which:

Fig. 1 is a side elevation;

Fig. 2 is an enlarged fragmentary longitudinal section;

Fig. 3 is a section on line 3-3 of Fig. 2;

Fig. 4 is a sectional View showing a modified form of guard; and

Fig. 5 is a perspective of a modified guard.

Referring now to the drawings, I show at 5 an air inlet pipe connected by adapter 6 into a conventional control valve I having an actuating lever 8. Into the discharge end of the valve there is connected an elbow 3 in which is threadedly mounted an adapter H3 having a restricted discharge tube ii discharging into a T l2 which has an inlet l5 connected into a syphon line Iii leading. for instance, from a cleaning solution tank not shown. Up to this point in the description, the structure is conventional, the passage of air under pressure through the device acting to syphon the cleaning solution from the syphon line.

Threaded into the discharge outlet of the T there is an adapter 253 having a reduced diameter outer end 2! onto which is secured, as by a clamp 26, a freely flexible rubber hose or tube 25. The hose is suspended from the neck 2! so that it is freely flexible and so that, in the well-known manner, the fluid under pressure passing through and being discharged from the discharge end 25a of the hose will cause it to whip or oscillate in a swinging manner.

I threadedly mount on the adapter 28 the internally threaded smaller end of an outwardly flaring or trumpet-shaped guard 38, which guard has an interior diameter at its smaller end of 5 Claims. (01. 299-18) about twice the exterior diameter of the hose and flares to an interior diameter at its outer end of approximately three times the exterior diameter of the hose, the extreme outer end of said guard having a peripheral flange 32 to catch any spray which might tend to be propelled backwards onto the user.

The length of the hose 25 and the interior shape of the guard depend upon the extent of the are about which it is desired the discharge end of the hose to move, the function of the guard being to control the limits of the arc about which the free end of the hose may move under the influence of the fluid pressure and to prevent the hose from kinking.

By the use of my device the operator may hold the guard stationary while pointing its open end towards the area to be sprayed or blasted and the oscillatory action of the hose in conjunction with the control afiorded by the guard will eflect a coverage of the area to be sprayed equivalent to that which would be aiiorded if the operator manually played the hose back and forth in the con- Ventional manner, except that with my guard a more uniform pattern is obtained.

I find that by reinforcing the discharge end 25a of the hose 25 to give added weight at that point, the oscillatory action of the hose is rendered more smooth by virtue of the somewhat pendulum-like action.

Also, while I show the guard as having a solid side wall, it will be understood that the major functioning parts are the outer end portion which limits the pattern of movement of the discharge end of the hose and the inner end portion which provides a mounting. For instance. a wire frame of the general shape of the guard 30 may be used, as shown in Fig. 5, wherein the frame 40 is comprised of wire rings ll and longitudinal retaining wires 42 welded to the rings.

I claim:

1. A spray device comprising a rigid spray nozzle adapted to pass fluid under pressure, a freely flexible extension tube secured to the discharge end of the nozzle and suspended therefrom where.- by to be swingable in response to action of fluid under pressure discharged therethrough, and a rigid, trumpet-shaped guard having its smaller diameter end secured to the nozzle around the tube and having its larger diameter portion surrounding the discharge end of the tube whereby to limit the swinging movement of the tube.

2. A spray device comprising a freely flexible spray tube capable of passing fluid under pressure and swinging laterally at its discharge end 3 portion in response to action of fluid under pressure passing therethrough, and a guard having a portion surrounding the tube at its extreme discharge end in normal spaced relation thereto whereby to be engaged by the tube during its swinging movement and thereby to confine the movement to a predetermine darea.

3. Theadevice of 'claim ZfWherein the guard is comprised of a plurality o'f''rings of relatively different inner diameters and retaining wires see curing the rings in spaced axial alignment.

4. A spray device comprising, in combination; with a flexible hose adapted to pass fluid under pressure, a relatively rigid circular'gua'rdsecuredtreme discharge end whereby to permit free swinging of the hose at and adjacent its discharge end, within the limits defined by said outer end portion, in response to the action of fiuid under pressure passing through the hose.

5. The device of claim 1 wherein the outer end portion of the guard presents a peripheral flange providing an annular spray shield,
