7 Claims.
This invention relates to the art of construction, building repair and the like, and more specically to apparatus for applying cernentitious substances, the primaryv object being to provide improvements in outlet nozzle structure for such equipment.
The most important .object of this invention is the provision of a nozzle for applying cementitious substances 4similar to that disclosed in U. S. Letters Patent No. 2,303,810, dated December 1, 1942, but having reiinements of construction rendering the same not only more .elcient in operation, but more particularly, appreciably longer lasting.
Another important object of this invention is to provide a nozzle adaptable to receive cemenytitious mortar under pressure and having a resilient tubular outlet spout so disposed Within a hollow mortar receiving 'body as to 'be eX- tremely resistant to wear and deterioration due to the action of said mortar thereagainst as it passes through the spout.
A further object of this -invention is the provision of a nozzle having a hollow body tele-- scopically receiving a tubular, rubber-like spout and a sleeve surrounding the spout in spaced relation thereto for holding the spout in place 4whereby the latter is free to -lex as mortar is forced therethrough.
v,Other objects will be made clear or 'become apparent during the course oi the following specification, reference being had to the vaccompanying drawings, wherein-z Figure l is a side elevational view of an outlet nozzle structure for material applying equipment made in accordance with the present invention, certain associated connections thereto being shown fragmentarily.
Fig. 2 is a substantially central longitudinal sectional View taken through the nozzle shown in Fis- 1; and
Fig. 3 is a transverse cross Sectional view taken such as that shown and described in the above identified patent.
The body IB has a Portion .of its length reduced in outside diameter as at I6 to telescopically receive the conduit I4 and an internal bevel I8 is formed vin bore I 2 adjacent the outermost end of said portion to facilitate free passage of the sand and cement mixture from conduit I4 into bore I2 of body I0.
The diameter of the bore I2 adjacentl that end of body I0 opposite to portion I6 is greater than the remainder of bore I2 at 20, presenting a continuous internal shoulder 22 facing outwardly toward said opposite end of body IIJ.
An elongated, resilient member 24 formed from rubber or the like and presenting an outlet spout for the substances to be applied by the nozzle is telescopically received by enlarged section 2li of the bore I2, a portion of member 24 extending outwardly a distance beyond body II). The inside diameter of the member 24 is substantially the same as the diameter of the bore I2 extending lfrom beveled end I8 to shoulder 22, while the outside diameter of member 24 is appreciably smaller than the diameter of section 20 of bore I2.
JA tubular sleeve 26, also extending into section 2t of bore I2 and projecting outwardly from body Il), but terminating inwardly from the outermost end of member 24, has an outside diameter less than the diametergof section 20 of bore I2 and an inside diameter greater than the outside diameter of member 24. This sleeve circumscribes a greater portion of the member 24 as is clearly illustrated.
The relative diameters of section 20 of bore I2, sleeve 26 and member 24, presents a space 28 between section 20 and sleeve'26 and another space '30 between sleeve 26 and member 24, the width of space 28 being substantially the same as the thickness of material from which the walls of member 24 is made.
The innermost end of the member 24 is rebent upon itself, overlapping the proximal end of .sleeve 26 as at 32 and extending as at 34 in overlapping relationto the marginal -edge of said end of sleeve 26. That portion 34 of member 24 is disposed within the space 28 while that portion 32 thereof abuts directly against the shoulder 22. The width of shoulder 22 is substantially equal to two thicknesses of the walls forming member 24, plus the thickness of the vwall of sleeve 26 and the width of space 30.
A manually operable valve 36 capable, when open, of' simultaneously admitting air and water from hoses 38 and 40 respectively, is joined to body IIJ through the medium of an elbow fitting 42. An inlet opening 44 formed in body I0 and communicating with bore l2, threadably receives a fitting 48 to which elbow 42 is connected. An L-shaped pipe 48 having its shorter leg tted into opening 44 in register with the fitting 4E, is disposed With its `longer leg in,l co-axial relationship with bore |2.- The openingv 44 is disposed between portion 'I6 of body IU and section 20 thereof and the long leg of pipe 48 terminates beyond the outermost end of sleeve 26 and spaced inwardly from the free end of member 24.
The hose 40 has connection with a source of liquid such as Water under pressure (not shown) while hose 3B communicates with a source of compressed fluid, also not shown.
In operation, the valve' 3B is opened to simultaneously admit air and water from hoses 38and 40 respectively into member 24 through pipe 48. Suction at the outlet end of pipe 43 created by the compressed fluid from hose 48 will `draw the sand. and cement mixture from This mixture will adconduit I4 into body I0. mix with the water emanating `from pipe 48 at a point spaced outwardly from the outlet end of pipe 48. The mortar of sand, water and cement passing from member 24 can then be applied as desired by manual manipulation of the entire nozzle structure.
It has been found by .actual practice that replacement of member 24 when made and disposed as above described becomes necessary only after long and continued use. The sharpedged, gritty sand-like particles as well as the cement used in the building substance, will Wear away member 24 very slowly compared with like members in other types of nozzle structures. of member 24 against which the material imping'es is freely suspended within body lil, unrestricted flexing thereof is made possible whenever `individual particles of such material contact the innermost surfaces of member 24.
No fastening means for member 24 and sleeve 2li to body l! is necessary other than a simple slipt since the pressure within body lil and member 24 adequately holds such parts assembled while in use. Thus replacement of member 24 and clearing of the entire nozzle is simply and easily accomplished. Furthermore, it
is obvious that cheapness of construction and durability of the entire assembly is one of its most advantageous characteristics.
Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent is:
