ADJUSTABLE NOZZLE TIP Filed Sept. 9, 1931 m ll l} mvgmon CCE'. Jacks on ATTORNEY Patented June 28, 1932 UNITED STATES PATENT OFFICE CLYDE E. JACKSON, 01 TRACY, CALIFORNIA, ASSIGNOR OF ONE-HALF '10 ALEXANDER NOWAK, 0F TRACY, CALIFORNIA ADJUSTABLE 'NQZ ZLE 'I'IP Application filed September 8, 1931. Serial Nof561,880.
This invention relates to nozzles used in the forceful spraying of materials such as cement, and similar materials in a semiliquid condition and which tend to settle,
and when the material is mixed with the necessary amount of water just prior to being discharged from the nozzle.
The principal object of my invention is to provide a nozzle for the purpose arranged so that a better mix will be obtained as the material is discharged; one which holds the material in a compact area and tends to pre-. vent the same from separating from the water; one which may be adjusted tocontrol the volume of discharge and one which may also be adjusted to increase the pressure of discharge if such has become excessively low. I
A further object of the invention is to produce a simple and inexpensive device and yet one ..which will be exceedingly effective for the purpose for which it is designed.
These objects I accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claims.
In the drawing similar characters of reference indicate corresponding parts in the several views:
Fig. 1 is a side elevation of my improved nozzle.
Fig. 2 is a cross section on the line 2-2 of Fig. 1.
Fig.3 is a fragmentary longitudinal section as on the line 33 of Fig. 1, showing a hose depressing finger in its retractive position.
Fig. 4 is a similar view showing the finger partly depressed.
Fig. is an end view of the nozzle showing the device for flattening or broadening out the end of the nozzle hose.
Referring now more particularly to the characters of reference on the drawing, the nozzle comprises a length of flexible resilient hose 1 the rear portion of which is mounted in and surrounded by a rigid metal sleeve 2. The sleeve on its rear end is provided with a threaded portion 3 wherby connection may be made with the; feed hose or pipe leading from the source of supply.
Intermediate.its ends the sleeve is provided with a plurality of longitudinally extending slots 4. These are arranged in equally spaced relation about the sleeve and are cut so as to extend spirally about the sleeve as plainly shown in Fig. 1. Projecting through and fitting'the slots from end to end are depressing fingers 5, which are pivoted at their rearends outwardly of the sleeve in connection with ears 6 formed on the adjacent portion of the sleeve. The fingers 1n- "crease in depth from their pivoted end toward the other, so that whentheir outer edges are parallel to the sleeve their inner edges are depressed inwardly of the sleeve in sloping relation thereto; and when their innerv edges are flush with the bore of the sleeve, their outer edges diverge relative to the sleeve from their pivoted ends. Said inner edges are preferably convexly curved both lengthwise and transversely as shown so as not to tend to out through or damage the hose which the fingers engage when they are depressed.
The outer edges of the fingers are threaded as at 7 in such relation to each other that the threads of all the fingers for a certain portion of their length will be simultaneously engaged by a hand turned nut 8 mounted thereon. The bore of the nut is of such size that it will engage the fingers adjacent their pivoted ends; and when so engaged will allow the inner edges of the fingers to lie flush with the bore of the sleeve or against the hose as shown in Fig. 3. The natural outward resilient pressure of the hose tends to hold the fingers constantly out and in engagement with the nut. Since of course the nut is nonexpansible the rotation and advancement of the same along the fingers will cause the latter toward their free ends to be depressed into the hose as shown in Fig. 4. This will diate the ends of the nozzle, the material is straightened out before it reaches the end of the nozzle andits discharge is therefore not accompanied'by an excessive throwing out laterally of the mixture as would otherwise be the case and which would interfere with the proper control or direction of the mixture.
In addition to the mixing of the material thus obtained, it may be desired for the nozzle to discharge a fiat instead of a rounded spray. I may therefore mount a rigid collar 10 on the outer end or tip of the nozzle hose. This collar is of oval form so as to permit of a horizontal flattening and consequent relative widening'of the hose at its tip. Such flattening is accomplishedwhen desired by a thumb screw 11 mounted in the top of the collar and engaging a flat washer or saddle 12 which bears on top of the hose. Turning down of the screw therefore will shift the hose from its normal round shape to one of a horizontally oval and relatively flat form to whatever extent may be desired.
From the foregoing description it will be readily seen that I have produced such a device as substantially fulfills the objects of the invention as set forth herein.
vWhile this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended claims.
Having thus described my invention what I claim as new and useful and desire to secure by Letters Patent is:
1. An adjustable nozzle comprising a length of flexible hose, and means associated with the hose to depress the same at will to form longitudinally extending spiral ribs therein.
2. An adjustable nozzle comprising a length of flexible hose, means associated with the hose to cause material being forced therethrough to be given a whirling movement beiiore being discharged from the nozzle, and means to place said first named means in or out of operation at will.
3. An adjustable nozzle comprising a length of flexible hose, and means associated with the hose to depress. the same at will to form longitudinally extending spiral ribs length of flexible hose, a rigid sleeve about the hose, said sleeve having longitudinally extending slots cut spirally therethrough, fingcrs fitted in said slots, the inner edges of said fingers bearing against the outer periphery of the hose, and their outer edges diverging lengthwise from one end relative to their inner edges, means pivoting the fingers at said one end on'the sleeve, and rigid means engaging the outer edges of all the fingers and movable therealong for depressing the fingers relative to the sleeve.
6. An adjustable nozzle comprising a length of flexible hose, a rigid sleeve about the hose, said sleeve having longitudinally extending slots cut spirally therethrough, fingers fitted in said slots, the inner edges of said fingers bearing against the outer periphery of the hose, and their outer edges diverging lengthwise from one end relative to their inner edges and being threaded, means pivoting the fingers at said one end on the sleeve, and a nut about all the fingers and engaging the threads of all the'fingers simultaneously, said nut being of a size to fit the fingers adjacent their pivoted ends.
7. An adjustable nozzle comprising a length of flexible hose, a rigid sleeve about the hose, said sleeve having longitudinally extending slots cut spirally therethrough. fingers fitted in said slots, the inner edges of said fingers bearing against the outer periphery of the hose, and means to depress all said fingers relative to the sleeve simultaneously.
8. An adjustable nozzle comprising a length of flexible hose, a rigid sleeve about the hose, said sleeve having longitudinally extending slots cut spirally therethrough, fingers fitted in said slots, the inner edges of said fingers bearing against the outer periphery of the hose, means pivoting the fingers at one end on the sleeve, and means to depress the fingers toward their opposite ends varying amounts.
In testimony whereof I aflix my signature CLYDE E. JACKSON.
