'v its outlet end.v An' internal screw thread I8 is Myinvention relates to improvement in liquid dispensing nozzles of the type generally used for dispensing motor fuel. Nozzles of this character are provided with nozzle-suspending means adapted for suspending the nozzle upon a bracketl formedlon ya connection head which is secured on the upper end of a standard, or supply pipe, and to which head one end of a hose is attached, with the opposite end of the hose attached to a nozzle, whereby the nozzle may be readily suspended upon the bracket when not in use.
'Ihe object of my invention is to provide a nozzle with a strainer for straining the liquid as it is discharged from the nozzle, and provide novel means for mounting the strainer upon the nozzle.
A further object is to associate the strainer and the nozzle-suspending means in such a manner that the nozzle cannot be suspended upon the bracket unless the strainer is properly replaced upon the nozzle after it has been removed for cleaning purposes.
These together with various other novel features of construction and arrangement of the parts, which will be more fully hereinafter described and claimed, constitute my invention.
Referring to the accompanying drawing:
Fig. 1 is a longitudinal sectional view of my improved nozzle, showing devices in elevation and adapted for suspending the nozzle.
Fig. 2 is an enlarged sectional perspective view of the strainer and the sleeve upon which the strainer is secured, shown detached from the nozzle.
Fig. 3 is a perspective view of the smooth end after the sleeve and strainer have been removed.
Fig. 4 is a sectional perspective View showing a modified form of the nozzle-suspending means.
In the drawing in which like reference characters refer to like parts, Fig. 1 shows a dispensing device which includes a standard or supply pipe 6, secured in an erect position and connected with a source of liquid supply. A fitting in the form of a head I is connected with the pipe 6, a hose 8 is connected with the head, and a nozzle I is connected with the free end of the hose in the usual manner.
The head 1 is provided with a bracket I2 for suspending the free end of the nozzle upon the head 1, when the nozzle is not in use. Said bracket I2 is provided with a side opening I3, through which the flanged end of the nozzle I0 may be readily inserted and supported by lips I and I6, forming part of the bracket I2.
In carrying out my invention I employ a nozzle I0 having a smooth outer cylindrical surface at screen, or strainer, V2,2
formed in the nozzle, as shown in Fig. 3.
-A sleeve 20 is provided with an external screw thread 2I and is adapted to be engaged by the thread I8 of the nozzle. A cylindrical wire mesh occupies the bore of the,
sleeve y2I1`iand is secured to the sleeve by means of solder 23. l
The strainer 22 fits loosely into the outlet end of the nozzle I0 and extends into the latter a sufficient distance beyond the sleeve 20 to present a large filtering or straining surface. The
inner end of the strainer 22 is pinched together and secured by solder 24.
The sleeve 20 is provided with a flange 25, or other suitable protuberance, which extends beyond the periphery of the nozzle, and forms bracket engaging means, adapted for suspending the nozzle from the bracket I2, as shown in Fig. 1.
The sleeve 20 and the ange 25 are preferably made in one piece, as shown in Figs. 1 and 2. The sleeve and flange may be formed separately, as shown in Fig. 4, wherein the sleeve 28 is provided with an enlarged head 28, adaptedfor engaging a flange, or washer, 3U, and securing the same upon the end of the nozzle. washer, 30 projects beyond the diameter of the nozzle and forms the bracket engaging means by which the nozzle may be suspended upon the bracket I2, when the sleeve and strainer are secured upon thenozzle.
The novel means for mounting the strainer upon the nozzle insures the replacement of the strainer upon the nozzle after the strainer has been removed for cleaning the same. By combining the sleeve and strainer as a removable unit, and arranging the sleeve for controlling the position of the flange'25, or the flange 30,' relatively to the nozzle, the nozzle cannot be suspended upon the bracket I2 until the sleeve and strainer are properly attached to the nozzle.
Should the attendant neglect to attach the sleeve, carrying the strainer 22, to the nozzle it will be impossible for him to suspend the nozzle upon the bracket I2, due to the smooth surface of the nozzle at its discharge end.
My invention insures the nozzle always being provided with a fuel strainer properly installed in the nozzle.
Various changes in the construction and arrangement of the parts may be made without departing from my invention.
