To all whom i may concern.'

Be it [known that we, FRANK MoLEs'rA, Jaco M. MoLns'rA, and DWIGHT S. Conn, citizens ot' the United States, residing, respectively, in laris township, in the county of Kent and State of Michigan, in Paris township, in the county of Kent and State of Michigan, and in the city of Grand Rapids, in the county of Kent and State of Michigan, haveinvented a new and useful Improvement in ySpray-Nozzles and Mountings Therefor, set V.darth in this specification and illustrated by the accompanying drawing, forming a part hereof.

Our invention relates to an improved spray nozzle and mountingt'herefor and more particularly to that type of such devices as are employed in connection with revoluble lines of pipes forming part of a showering systemfor use in greenhouses, gardens, etc.

The objects of our invention are toipro.

vide a spray nozzle and mounting therefor which may be easily and securely applied to a line of pipe; rende s the repeated removal and replacement of t ie nozzles for cleaning or change of size easy and practical; enables nozzles of the deiector type to be easily-and accurately set with respect to the direction of their discharge; provides simple, durable and tight joints that are not liable t'o get out of order, and accomplishes these objects with parts that are simple and easily produced. These and. other objects of our invention will more fully appear from the following description.

Our invention consists essentially of the various novel features of construction, combination and arrangement of parts hereinafter more fully described, and particularly pointed out in the appended claims, and the accompanying drawing illustrates severalv variations in the forms which the parts may have without departing from the essential common principles of the invention.

A spray nozzle and mounting constructed in accordancerfwith our invention comprises in combination a pipe having a screwthreadedl orifice in the wall thereof; a` bushing having a screwfhreaded portion adapted to screw into the said orifice inthe pipe and make a tightjoint,therebetween; a head on said bushing whereby the bushing may be turned by a suitable tool to screw the bushing into or remove it from the pipe; a socket in the bore of said bushing, and a nozzle having a stem portion adapted to pass through the bore of said bushing and provided with suitable 'surfaces t engage the said socket and be secured therein by the frictional contact of the engaging surfacesthe contact of said engaging surfacesl forming a tight joint between the socket and stem of the nozzle. v

An additional feature of our improved spray nozzle and mounting consists in making the head portion of the nozzle larger in diameter than the, stem which passes through the bushing and-'to have the bottom face of the head portion somewhat spaced apart from the top face of the bushing so that 1asuitable tool may be applied in thefreces's thus formed to lift and free the nozzle from tight engagement in the socket when it is desired to remove the nozzle from the bushlng.

Referring now to the drawingz Figure l is a side elevation of a piece of pipe having our improved bushing, and a nozzle therein, secured in the wall thereof; Fig. 2 is a transverse section on line ABof Fig. l.; Fig. 3 is an exterior side viewofthe nozzle shown in section in Fig. 2; Fig. l is a central sectional elevation yof a collar, similarlyV shown inthe assembly in Fig. 2, whichis employed in this Jform of our improved mounting; Fig. 5 is a central sectional elevation of the bushing employed in this form o .our i-m- `proved mounting, showing the Aform of socket therein; Fig. 6 is a top view f Fig. 7; Fig'. 7 is a central sectional elevation of a bushing and nozzle therein of a second form of our improved mounting; Fig. 8 is an exterior side View of the nozzle shown in section in Fig. 7 Fig. 9 i-s a central sectional elevation of the bushing employed in the -second form of our improved mounting,

To overbushing, which provision enables the nozzles to be set facing any desireddirection; suite able contacting surfaces on the stem of the nozzle to engage suitable surfaces of the bushing to enable suiiicient friction to be,

set up between the said contacting surfaces as to hold the rozzle securely in place by friction alone against its expulsion by the pressure of the water in the pipe, and this friction grip provides for the'repeated easy removal and perfect and easy replacement of the nozzle in the socket of the bushing when conditions so require, thus perfectly satisfying that requirement of service.

The parts of our improved mounting are shown full size, for the designated service, by the drawing and an inspection of the drawing will show that the parts are simple in Vform and capable of being easily and cheaply made.

In practice, the bushing of our improved mounting is screwed into the tapped orice in the wall of the pipe, until a. leak-v tight joint is made therebetween, then the nozzle is placed in position /with its face in the desired direction and a light rap or blow on y(top 22 of the nozzle drives the contacting surfaces together so tightly as to setl up sufiicicnt friction therebetween to clamp the stem of the nozzle securely and thus hold the nozzle in place against such pressures as are ordinarily used in this service. l

ln the form of our improved mounting shown by Figs. 1, 2, 3, d and 5, the soft metal ring 9 is compressed between shoulders S and 19, when the force of the blow on head acts to drive the said shoulders together, and `this swaging action causes the soft metal of the ring to How laterally and its side surfaces to thus make intimate contact `with the respective surfaces to which they are opposed, thus sealing the stem of the nozzle in the bushing leak-tight and secu-re by the friction set up betweeithe lateral contacting surfaces of the mounting. The soft metal of ring 9 will readily hold to permit of withdrawing the stem of the nozzle repeatedly therethrough and as readily yield to swagings to repeatedly close the joint as securely as at first.

In all of the forms of mountings shown by the drawing the stem 12 of the nozzle makes a close yet free fit in the lower part of the bore fi'of the bushing, which provision assists in making all forms of the mounting eifective.

In the form of contacting surfaces shown in Figs. 7, 8 and 9 the zone-shaped surface 25 makes linear annular contact with the surface of the slightly conical socket 24; and a rap on the head or top of thev nozzle forces the contacting surfaces together so intimately as to produce a leak-tight and suiiiciently secure joint therebetween.

The form of contacting surfaces shown by Figs. 10, 11 and 12 produces annular contact between the annular edge 31 and the slightly conical surface 26, and, as-dthe parts of our improved mounting (except ring 9 are preferably made of a malleable compo.- sition of metals, as brass, the effect of a rap on top 22 of the nozzle is to force the contacting surfaces 26 and 31 intimately together and thus make a leak-tight and secure friction joint therebetween.

The form of contacting surfaces shown by Fics. 13, 14e and 15 is truly and slightly conical, and cone 2S accurately fits into conical socket 27, so that when forced together by a rap on top 22 of the nozzle the conical surfaces come into such intimate contact'as to form a leak-tight and adequately secure joint for the purpose.

In the form of mounting shown by'Figs. 17, 19 and 2O an annular marginal collar 29 of the form shown is provided on the top of the bushing and an annular shoulder 30 is provided on the nozzle to contact with the top edge of the said collar to the end that when these parts are forced together by a rap on top 22 the collar 29 will be swaged andcompressed tightly around the stein 12 so as to form a leak-tight joint therebe tween to adequately secure the nozzle in the bushing.

lVhile we have shown several of the forms which the contacting surfaces in our; im proved mounting may be given we da not limit ourselves to the specific formsshown and described, but would include as within the scope of our invention all forms f frictional contacting surfaces which produce a leak-tight and sufficiently secure .joint tol serve the purpose, substantially as described.
