FLUID STREAM AND SPRAY GUN HAVING A CLEAN OUT PIN Filed Sept. 23, 1949 INVENTOR. HAROLD A. ROSELl/ND,

Patented Jan. 20, 1953 FLUID STREAM AND SPRAY GUN HAVING A CLEAN OUT PIN Harold A. Roselund, Dayton, Ohio, assignor to C. W. Harwin Ina, Dayton, Ohio, a corporation of Ohio Application September 23, 1949, Serial No. 117,461

9 Claims. (01. 299-59) This invention relates to a fluid stream and spray gun of the general type used for dispensing liquids of various kinds and represents an improvement over the gun shown in my earlier Patent No. 1,900,668.

Guns of this type are frequently used in places where they are given very rough treatment and therefore must be designed to withstand much abuse and at the same time must be made to sell in competition with low cost inferior designs. It is an object of this invention to eliminate the need for using a large number of precision parts or parts which are quick to bind if not assembled with care.

Another object of this invention is to provide a low cost dispenser having a very simple and handy means whereby the fluid may be dispensed either in the form of a fine spray or in the form of a fluid stream.

The nozzle opening in guns of this general type frequently becomes clogged either because of sediment which may be present in the fluid to be dispensed or because of dirt entering the nozzle opening. It is, therefore, necessary to provide some convenient means for quickly clearing out obstructions from the nozzle outlet. It is an object of this invention to provide a spray gun in which an improved means is provided for thus clearing obstructions for the nozzle.

More particularly, it is an object of this invention to provide a spray gun in which operation of a single button is used for either cleaning the nozzle or for changing the characteristics of the fluid stream leaving the nozzle.

Other objects and advantages reside in the con struction of parts, the combination thereof and the mode of operation, as will become more apparent from the following description.

In the drawing:

Figure 1 is a vertical sectional view showing the general construction and arrangement of the parts;

Figure 2 is a sectional view on an enlarged scale taken substantially on line 2-2 of Figure l;

Figure 3 is a sectional view on an enlarged scale showing the nozzle construction;

Figure 4 is a sectional view taken substantially online 44 of Figure 3; and V Figure 5 is a sectional view taken substantially on line 55 of Figure 3.

Referring now to the drawing wherein. I have shown a preferred embodiment of my invention, reference numeral I0 designates the main liquid receptacle which is adapted to contain a supply pf liquid to be dispensed. Reference numeral I2 designates a pistol grip type of handle which is provided with a conventional screw threaded connection Hi to the receptacle 0 as shown. A suitable gasket is provided between the upper end of the receptacle l0 and the handle l2 so as to prevent th leakage of liquid at this point. The handle I2 is preferably in the form of a casting which serves not only as a handle but also serves as a support for the pumping mechanism and the dispensing nozzle and nozzle control mechanism. The nozzle I8 is screw threaded or otherwise secured to the outer end of the pipe 20 which in turn is supported adjacent the upper end of the handle l2 and which has its central passage communicating with a central passage 22 formed in the handle I2.

A self aligning piston guide bearing 23 is loosely carried by the lower end of the handle, as shown. The connection between the bearing 23 and the handle is a threaded connection in which the pitch diameter of the threads on the bearing 23 is one to two hundredths of an inch less than the pitch diameter of the threads on the handle. The clearance between the threads constitutes a labyrinth passage through which air may freely enter to replace the oil dispensed but through which only a negligible amount of oil would ever pass. This clearance thus serves a multiple purpose. A set screw 25 is used to prevent unscrewing of the guide after the parts are once assembled.

A tubular extension 24 is threaded to the guide bearing 23 and this extension serves as a pumping cylinder in which a plunger 26 is adapted to operate. The plunger 26 is a conventional cupshaped member as shown in the drawing and is carried by the lower end of a hollow rod 28 which is supported for sliding movement within the guide bearing 23 carried by the handle l2, as shown. Upon downward movement of the plunger, the fluid being pumped rushes past the plunger, but upon upward movement of the plunger, the fluid above the plunger is forced upwardly ahead of the plunger in accordance with well-known principles. Leakage of fluid between the rod 28 and the bearing 23 is prevented by means of a fluid seal 32 which is prefrably in the form of an 0 ring disposed within a circumferential groove formed on the rod 28. The upper end of the rod 28 slides within the central fluid passage and guide recess 22 formed in the handle 12. A similar fluid seal 34 is provided at the upper end of the rod 28, as shown, so as to'prevent any leakage between the rod 28 and.

3 the walls of the fluid passage 22. The clearance between the threads on the handle 12 and the guide bearing 23 eliminates the danger of binding between the rod and either the bearing 23 or the handle I 2.

Reciprocation of the piston 26 is produced by operation of the bell crank lever or trigger 36 which is pivotally supported on the handle [2 by means of a fixed pin 39. When the operator applies pressure on the bell crank lever 38, the piston rod 28 is pulled upwardly by means of the connecting link 40 which has its upper end journalled in the bell crank lever 36, as indicated at 42, and which has its lower end arranged to engage a shoulder 44 provided on the rod 28. A coil spring 46 serves to bias the piston rod 28 downwardly at all times and consequently as the pressure on the trigger 36 is relieved, the piston rod 28 moves downwardly.

I Fluid to be pumped enters the lower end of the pumping chamber 24 through a check valve 48 which allows free flow of fluid into the pumping chamber but prevents the escape of fluid therefrom when the piston 26 moves downwardly. As the piston 26 moves upwardly, the fluid which has entered the cylinder chamber 58 is forced through the aperture 54 into the hollow passage 52 provided in the piston rod 28. As the piston rod continues to move upwardly, the fiuid trapped in the chamber 50 isforced up through the passage 52, the passage 22 in the handle [2, the pipe 20, and is discharged out through the nozzle I8. Any air which may be trapped in the pumping chamber 58 may escape through the hole 55 in the side wall of the piston rod 28. A portion of the rod 28 is cut away directly beneath the hole 55 as indicated at 57, so as to allow air to escape even after the hole 55 moves up into the bearing 23.

In order to control the flow of fluid from the nozzle,- there is provided a rotatable element 68 within the nozzle which is provided with a screw threaded connection to the inner wall of the main nozzle housing. The location of the member 60 within the nozzle may be changed by rotating the button 62 which is drivingly connected to the outer end of the plunger 64. The plunger 64 may be either rotated or reciprocated. A spring 66 serves to bias it into the position in which it is shown in Figure 1 of the drawing. However, pressure on the button 62 serves to reciprocate the plunger 64 so that the projecting pin 68 carried by the plunger 64 enters the nozzle orifice 18 so as to clear out any obstructions that may be lodged therein. This reciprocation of the plunger 64 does not change the location of the element 68, as the flattened end portion 12 of the plunger 64 is free to slide within the slot 14 which is'provided in the end of the member 68.

By turning the button 62, the member Bil will be moved toward or away from the outlet orifice in the nozzle, depending upon the direction of rotation of the button. The member Si] is provided with one or more grooves 82 adjacent the outer end which are so arranged that when the member 68 moves toward the orifice, the grooves cause the liquid passing between the member 68 and the nozzle wall to flow in a direction tangential to the walls of the orifice 10 so as to cause the liquid to leave the nozzle in the form of a fine spray. These grooves have no appreciable effect when the element 68 is moved toward the rear and consequently the liquid then leaves the nozzle in a solid stream or let. Thus, when the member 68 is moved away from'the 4 outlet of the nozzle by rotation of the button 62, the liquid will be delivered from the nozzle in a solid stream, whereas if the member 16 is moved up toward the nozzle outlet, the liquid will leave the nozzle in the form of a fine spray.

The member 50 is a hollow screw machine part which may be manufactured very cheaply and still have the necessary accuracy required. Apertures 76 are provided in the side walls of the member 60, as shown, so that the liquid coming through the tube 2i? can find its way to the orifice 18. Both ends of the plunger 64 are flattened, as shown, and loosely fit within slots in the members 68 and 62, as shown. By virtue of this construction, there is no trouble in obtaining proper alignment of the parts and all danger of binding has been eliminated. A suitable seal 18 has been provided on the shank of the button member 52 so as to prevent leakage between the member 62 and the opening in the handle I2 through which the member 62 slides.

A screen 88 has been provided at the inlet to the pumping chamber, as shown, so as to prevent dirt particles from entering the pumping chamber.

Although the preferred embodiment of the device has been described, it will be understood that within the purview of this invention various changes may be made in the form, details, proportion ahd arrangement of parts, the combination thereof and mode of operation, which generally stated consist in a device capable of carrying out the objects set forth, as disclosed and defined in the appended claims.
