"UNITED STATES 'emr-consume. gappuemu'n mea January 15, laas. serial 110,012,851. i
Be it known that I, THOMAS HAMM, a
citizen of the United. States, and resident of Hawthorne, in the county of Los Angeles and State of California, have invented new and useful I in rovements in a Cement-Gun Nozzle, of which the following 1s a speci-v ication. Y This invention relates to a nozzle for use in .building structures of cement or plastic material by spraying the same under pressure upon a'f ackgr'onnd. The present inparticularly to the tip In operations of this character a mixis4 blown into a nozzle. In its passage through the nozzle, water is supplied thereto and mixed therewith, to form a wet cement-or concrete, which issues therefrom and is directed in a stream and at a high velocity upon the background. -Under these conditions the cement is impacted uponl the background and pneumatically rammed to form a dense cementitiousmass. The nozzles as at `present used, are tapered to a smaller diameter at the exit or discharge f tained by means of the embodiment of my ves invention illustrated in the accompanying drawing, in which: i
Fig. 1 is a side elevation of a nozzle; and Fig. 2 is an axial section therethrough.
Referring more particularly to the drawing, a water 'ring is indicated by 3. It is provided with threaded bores separated by an annular water chamber 4 having spaced openings 5 to direct water inwardly. A. threaded nipple 6 serves for a connection to a water line indicated generally by 7. The nozzle tip may be formed by two sections 8, which when laced together form a cylindrical member avng a bese or. en-
'rnonas um, or- HAWTHORNE caLIrnNrA.
Within the tip is a lining 10, preferably of rubber. This lining has a flange 11 at the bottom, which is clamped between the ring and the base of the tip. The bore of the lining is tapered from its lower end, decreasing in diameter to its junction with a mixing chamber indicated generally by 12. This chamber is formed by flaring the bore outwardly-to a larger diameter then tapering inwardly. Near the upper or outer end annular shoulders 1 3 are formed which 'comprise chokes. The inventive feature resides in the enlarged mixing chamber and f the chokes.
The cementitious ingredients, such as sand and cement are blown througha hose 14 into the ring 3. aber passes through the water line 7 and apertures 5 to the cementand sand. 'lfhe cement, Water and sand isA mixed in their passage along the lower tapered portion of the nozzle and spread as they enter the mixing chamber portion 12. Here a more intimate mixture of the ingredients is obtained. The wetv cement then 'passes through the portion of the nozzle containing the chokes. These contract the stream and at the Sametime assist in mixing. `The cement finally issues in a compact stream without any substantial spreadin What claim is:
1, A. cement gun nozzle having a cylinl droidal passage provided with an. annular choke shoulder adjacent its discharge end. 2. A cement gun nozzle having a cylindroidal linin provided internally with an annular cho e shoulder adjacent its dischargeend. v
3. cement gun nozzle having'a passage with a mixing chamber of larger diameter intermediate its ends, a portion contracting from said mixing 'chamber towards the discharge end of'said nozzle, and an annular cho e shoulder in said passage adjacent said discharge end.
j 4. A cement gun nozzle having a passage .contracting from the inlet end towards the discharge end, a mixing chamber of larger diameter intermediate its ends, and an annular choke shoulder in said passage adjacent the discharge end.
5.A cement gun nozzle having a provided with a passage having amixing ends, a portion contract` chamber of larger diameter intermediate its from said mixing chamber toward the dlscharge end; and an annular choke shoulder in said passage adjacentthe discharge end.
6. A cement gun nozzlehavinuz lining provided with a passa expan g from the inlet 'end toward t e discharge end, a,
' mixing chamber of larger diameter inter mediate its ends, a portion contracting from. said mixing chamber toward the discharge end, and an annular choke shoulder in said passage adjacent said discharge end.
In witness .that I claim the fore oin'g I have hereunto subscribed my name t is 9th 'day of January, 1923.V
