OLE ELYRIA, OHIO HOSE NOZZLE Application filed March 9,
This invention is directed to a novel type of nozzle which is primarily intended to be used in conjunction with a hose or similar water distributing apparatus. The invention has for one of its objects, the provision of a nozzle which is readily susceptible to change so that it may deliver either a socalled full, or continuous stream, or else a spray or spreading stream of the fluid.
In carrying out my idea in actual practice, I employ a nozzle comprising a main body member that is adapted for engagement with a water line. This main body member is reduced at one end, and the end thereof is partially closed, leaving an opening through which the water passes. IVhen a comparatively full stream is to be delivered, this main nozzle member is employed alone.
However, should one be desirous of having the water distributed in a spray, a small device is placed in the reduced portion of the nozzle member prior to its being fastened to the water line. This device substantially closes the bore in the reduced portion, but has spiral grooves on cylindrical surfaces thereof which function to direct the water through the opening in the end of the nozzle in diverging directions, thereby accomplishing the desired result.
To the end of facilitating the change above indicated in the nozzle, the device aforesaid is provided with a handle or gripping member by which it is readily removed or inserted 5 in the bore of the nozzle.
A particular noteworthy feature of the invention is the construction of the closing device for the nozzle, which is hollow in character. This incorporates the property 40 of resiliency into the cylindrical walls thereof which engage with the walls of the nozzle and insure a tight fit between these parts. This sealing effect adds to the efiiciency of the spraying apparatus because it causes all the fluid to be directed through the spirals on the device in the nozzle.
A nozzle provided by my invention is particularly characterized by its simplicity of construction and ease of manipulation, as well as ready replacement of parts should vided with screw threads as shown at 7 for 1928. Serial No. 260,473.
any of them become worn out or ineffective for any reason.
Further and more detailed objects of the invention will in part become apparent and in part be hereinafter stated as the description of the invention proceeds. For a full and more complete understanding thereof, reference may be had to the following description and accompanying drawings, in which Figure 1 is a view in side elevation of a nozzle provided by my invention.
Figure 2 is a vertical section through the nozzle shown in Figure 1, taken about on the line 22 of Figure 1, with the closure device for the reduced portion of the nozzle removed.
Figure 3 is a horizontal section taken about on the line 3-3 of Figure 1, with the closure member in place.
Figure 4: is a detailed view in side elevation of the closure member, and
Figure 5 is a fragmentary View in section similar to Figure 2, but with the closure member in operative position.
Figure 6 is a plan view of the front end of the whirler member.
While a preferred embodiment of the invention is herein specifically set forth, it is to be understood that I am not to be limited to the exact construction illustrated and described, because various modifications of these details may be provided in putting the invention into practice within the purview of the appended claims.
The main body portion of the nozzle is shown in Figure 1 and designated by the reference character A. To facilitate the handling of this member, it may be provided with knurled gripping surface shown at 1. 99 The main nozzle member A comprises a portion 2 of comparatively large diameter and a reduced ortion 3 having its end substantially closed but provided with an opening as shown at 4. By reference to Figure 2, it will be noted that the member A is provided with a bore having substantially two diameters indicated at 5 and 6.
IVhile I have shown the larger bore 5 prothe purpose of attaching the nozzle to a 'atcr line, it is to be understood that I may avail of any known type of connection for accomplishing this purpose. The large portion 2 and reduced portion 3 of the member A define therebetween a shoulder 8, and a packing member 9 rests againstthis shoulder interior of the member A and is provided with an opening so as not to hinder the flow of water. When the device is assembled with a hose, the end of the hose abuts against the packing member 9.
The structure ust described is capable of delivering water in a so-called full stream, but should a person be desirous of distributing the water in spray form, my novel closure member may be employed. Referring to Fi ure 4, this member comprises a hollow cy indrical member 10 which is open at one end and closed at the other, as shown at 11, and has afiixed at the bottom 11, a handle or gripping member 12. Spiral grooves 13 are formed in the walls of the member 10 in any preferred manner such as by deforming the metal. 'hen the member 10 is inserted in the reduced bore 6, the bottom portion 11 substantially closes the bore and causes water to pass through the spiral grooves 13. This gives the water an angular or diverging direction as it passes through the opening 4 and provides the desired spraying action. The open end hollow construction of the member 10 lends thereto the tea ture of resiliency, which effects a tight seal between the cylindrical walls of the member 10 and the walls of the reduced bore 6.
In changing the nozzle to perform the desired function, all that is necessary is to remove the member A from the water line and either insert or remove the closure member 10.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent in the United States, is-
1. A nozzle of the class described, comprising, in COlIlbllliltlOl], a main body mem ber having a bore therethrough, said body member also having a substantially closed end with a small opening therein adapted to have water pass therethrough and with the bore gradually tapering to the opening, means in said bore for directing water through the opening in the body member in a spray, said means consisting of a hollow cylindrical member closed at one end and having spiral grooves in the cylindrical surface thereof, with the open end disposed towards the opening in the end of the body member, the walls of the cylindrical member being in engagement with the walls of the body member defining the bore, and operatin means for inserting the cylindrical meniber in the body member:
2. A nozzle of the class described, comprising, in combination, a main body mem-
