R. J. LENNON May 3, 1966 HOSE NOZZLE Original Filed May 18, 1962 INVENTOR ROBERT J. LENNON BY 65 a ATTORNEY United States Patent 4 Claims.

Matter enclosed in heavy brackets appears in the original patent but forms no part of this reissue specification; matter printed in italics indicates the additions made by reissue.

This invention relates to a hose nozzle and more particularly to a hose nozzle in which the water flow can be controlled by a thumb actuator.

Hose nozzles of the prior art generally utilize a rotatable spray control, a control rod being slided relative to an aperture from which the spray is emitted as the outer body of the nozzle is rotated relative to an inner portion thereof. Such rotatably controlled nozzles have the disadvantage of requiring two hands to effect an adjustment. The rotatable member also tends to become diflicult to rotate after even moderate periods of use, and with rotation thereof the hose coupling tends to become loosened as the spray is adjusted, resulting in leakage which is often quite discomiorting to the operator.

To overcome some of these shortcomings, the pistol grip controlled nozzled was developed. Most pistol grip nozzles. however, require that the operator hold the grip against a biasing spring and the back pressure of the water stream in controlling the spray making it somewhat difiicult to adjust the spray to the desired amount. In addition, most of these devices tend to develop leaks around the actuator parts.

The device of this invention overcomes the shortcomings of the prior art devices by providing a novel thumb actuated spray control. The spray control once positioned will maintain the spray at the desired point without further actuation by the operator. Little force is required to position the actuator in view of the fact that the spray control means is substantially isolated from the eifects of the pressure of the water stream. The possibilities of nozzle leaks are minimized by effectively sealing off the actuator from the water How and by eliminating the necessity for rotation of the nozzle in controlling the spray.

In the device of the invention, a hollow block is contained within the water conduit and fixedly attached thereto. The inner hollowed out portion of this block is maintained substantially in watertight relationship with the corn duit. Control rod means for controlling the water flow from the conduit is slidably mounted inside the block and protrudes through an aperture at the end of the block into the conduit. The end of the control rod which protrudes from the block through a hole surrounded by an O ring is adapted to mate with the aperture formed in the end of the conduit from which the water is emitted. Actuator means which protrudes through the conduit and is located along the outer wall thereof is connected to the control rod within the block. This actuator means is used to slidably position the control rod relative to the aperture through which the water is emitted to regulate the spray. The actuator means is thus isolated from the water ilow and the control rod is isolated from back water pressure by means of the watertight block in which they are fitted.

it is therefore an object of this invention to provide an improved hose nozzle.

it is a further object of this invention to provide a hose nozzle capable of thumb control in which the spray once adjusted will he maintained without the application of pressure to the control.

Re. 26,013 Reissued May 3, 1966 It is another object of this invention to provide an improved hose nozzle of simple construction which is not prone to leaking.

It is still a further object of this invention to facilitate the spray control of hose nozzles.

Other objects of the invention will become apparent from the following description taken in connection with the accompanying drawings of which- FlG. l is an exploded perspective view of a preferred embodiment of the device of the invention;

FIG. 2 is a cross-sectional view of the embodiment shown in FIG. 1; and

FIG. 3 is an enlarged cross-sectional view of the embodiment of FIG. 2 taken along the plane indicated by the line 33 in FIG. 2.

Referring to the various figures, conduit 11 which forms the main body of the nozzle has one end thereof 12 adapted for threadable attachment to a hose fitting. Conduit 11 has a spray diffuser l4 removably attached to the other end thereof from which the spray is emitted. Spray diffuser 14 may be threadably attached to the main portion of the conduit by means of mating threads 15 and 16 or may be attached by other suitable means such as, for example, a press fit design. Fitted in a recess formed in the spray diffuser is an O ring 17. The spray diffuser should be removable from the main body of the conduit to permit replacement of O ring 17 when necessary.

Contained within conduit 11 and fixedly attached thereto is a block 20. Block 20 may be fixedly attached to the inner wall of conduit 11 by means of screws 22 and 23 or other suitable means. Block 20 may also be integrally formed with conduit 11 by means of a casting process. The latter means of fabrication may be found to be more economical. Slidably mounted in a channel 26 formed in block 20 is control rod 24. Control rod 24 is supported for motion along an axis passing substantiaily through the center of aperture 25 in the end of the diffuser 14 which forms the end of the conduit. Block 20 has an aperture formed in one end thereof through which rod 24 passes. An 0 ring 27 is fitted in a groove in the block at the end in which the apcrture is formed. The shoulder portion 24b of the rod is adapted to mate with the end of the conduit surrounding aperture 25 to seal off this aperture when it abuts against 0 ring 17. Ditlusion of the spray is effected by tip portion 24a of the rod.

A thumb actuator 30 for slidably positioning rod 24 in channel 26 is attached to rod 24 by means of a coupling shaft 30a which is fixedly attached to the rod, for example by mating threads or a press fit.

The inner portion of block 20 is maintained in Watertight relationship with the inside of conduit 11, the only possible leakage path therebetween being sealed off by means of the sealing abutment of the wall of rod 24 against 0 ring 27. Thus, there is no means by which water may enter block Jill and therefore no leakage can occur around the edges of thumb actuator 30.

in the device of the invention, the water stream flows from the end 12 of the conduit through passageway 32 formed between the walls of the block and the conduit to the diffuser end of the conduit from which it is emitted. The spray is varied in accordance with the position of control rod 24 relative to aperture 25, the stream being completely cut off when the shoulder portion 24b of this rod is in abutment against 0 ring 17. In view of the fact that there is no significant back pressure of the water stream acting on control rod 24, this rod will hold any position it is slided to by means of actuator 30 without the operator having to hold the actuator.

If so desired, block 20 may be fabricated so that it can be press fitted into the conduit. This can be accomplished, for example, by making the block broader so that the top and bottom walls thereof abut against the conduit walls in a press fit. Passageway 32 then would be split into opposite portions formed between the vertical walls of the block and the conduit.

In place of actuator 30, an actuator which is pivotally supported on conduit 11 may be used with slidable motion of rod 24 being achieved by as the operator pivots the actuator with his thumb.

Although the invention has been described and illustrated in detail, it is to be clearly understood that the same is by way of illustration and example only and is not to be taken by way of limitation, the spirit and scope of this invention being limited only by the terms of the appended claims.
