4 Claims.

My invention relates to fluid fixtures.

In fluid fixtures it is desirable to provide an outer surface or finish which is durable as to its wearing quality-and also neat in appearance. In order to provide such fixtures, it has generally been the practice to form on a fitting a plating of stainless metal such as chromium.V Such xtures have been unsatisfactory because the plating is thin and easily injured, due to the soft base formed by the fitting, which is usually cast of brass or white metal. It has also been proposed to cast fittings entirely of stainless metal such as archromium alloy, but such methods are impracticable because the costisprohibitive. Moreover, imperfections such as blowholes in the castings produce unsatisfactory fixtures.

One object of my invention is to provide an improved fluid ixture having an outer surface of metaLvsuch as a stainless alloy, which is strong, durable and not easily injured.

Another object of my invention is to provide an improved fabricated fluid xture wherein a shell pressed from sheet metal forms the outer surface of the fixture and houses a fitting or fittings constituting the internal part or parts of the fixture.

The above and other objectsand novel features of my invention will become apparent from the following description and the accompanying drawings, in which,

and

Fig. v5 is a sectionalview of the fluid-delivery conduit shown in Fig. 1 after it has been bent to shape so that it will fit Vin the shell shown in Figs. 3 and 4.v

In the description which follows and inthe claims, I have employed the term fitting broadly to include the enclosed internal part or parts, and the term fixture to include the external housing and the internal part or parts constituting the fitting.

Referring to Figs. 1 to 5, inclusive, the fabricated fluid xture embodying my invention is generally employed on modern type wash basins and includes a fitting comprising a water delivery conduit I0 and a waste-stopper control member or y rod II.- The delivery conduit I0 is preferably a seamless tube bent at I2 to form the horizontal spout portion I3, which is of elliptical cross-section and bent downward at its outer end, as indicated at I4, so as to direct the delivery orifice I5 properly over the basin. The vertical downwardly extending portion I6 of the delivery conduit may be threaded at its lower end to receive a connection Il which in turn is connected to a suitable source of water under pressure. Where the delivery'conduit ID is intended to deliver av tempered mixture of hot and cold water, as is usually the case with this type of fixture, the connection is preferably a T, for receiving hot Water-'on one side and cold water on the opposite side. YThe waste-stopper control rod II moves vertically within a guide bushing or tube I8 which' is threaded at its upper end to receive a nut I9.

When the normal friction between the guide bushing I8 and rod tain the rod in any desired position, the nut I9 may be employed to tighten a small packing of fibrous material I9a wound around the rod II. The upper end of handknob 20, and the lower end thereof may be connected in any suitable manner to the stopper lever of the basin.

Inaccordance with my invention, I provide an improved fabricated fixture by arranging a shell II is not sufficient to main--V the rod is provided with a I 2 I. formed of ductile sheet metal about the above The shell 2| comprises a longitudinal portion y 22 and a hemispherical dome 23. The longitudinal portion 22 forms an annular tube of elliptical cross-section which surrounds and con- K tacts the spout shown in Fig. 2. The

thereof to receive the threaded upper end of the I3 of the delivery conduit I0,Vas

hemispherical dome 23 is provided with a threaded opening 24 at the top- *shape o x3p1ess the walls of the trough portion` stopper red II exten-ds.` duit I Il, which may be formed of either seamless guide bushing I8 to which is secured the nut I9. As will'be noticed in Fig. l, the lower end of nut I9 is recessed at 25 so that the nut will seat over the upturned edge of the shell at the threa-ded opening 24, thereby providing a neat appearance to the fixture. rIhe dome 23 encloses the upper end of the guide bushing I8, the portion of the .spoutfiadja'ent the bend I2 of the delivery'conduit Hij-and the'bend I2"of the delivery conduit.

For clamping the dome 23 to the shelf 26v an outwardly extending flange 28 at its upper end is provided. The liang'edlendof this bushing is welded to the inside of the Vrdome at 29, slightly above its lower edge, soV that V'a putty ring may easily be formed when the fixture is secured to the shelf of the basin. In'forder. to provide a strong and unitary fixture structure, the lower end of the guide bushing Itiand the vertical portion I6 of? the delivery conduit I0, both of which extend through the `clamping bushingV 2'I., are tack welded toeach Otherand also to the inside wall of the bushing Z'Iat 30, andy 3l, respectively.l The clamping bushing 2I, is externally threaded to receive aclanfiping` nut, 32 to, secure theiixture tightly to` the basinl shelf 26. ItV canthus be seen that I have provided a unitary uidxture .which is risidin construction and which effectively encloses and supports thev internalpartsor iittings.` Moreover, the Stainless Sheet.: metal vfonrllne the outside surface of the xture insures a nish which is neat. inappearan, not easily injured, and. does, :net uear away after continued use f,

I prefer to make the ixture structure described above by forming the she l 1 2 l fromductile sheet metal, such as a stainless metal alloy, in suitable dies. When the shell 2I is received from the dies, the bottom thereof lis opensc that the longif tu-dinal' portion 22 is in the shape of atrough. At the porti-on of the dome and spout at and adjacent their junction, the side` walls of the shell as received Vfrom theA diesV the'oth'er portions, as indicated at 33 in Fig. 3, .order to compensate for the closing of the dome circle'in thefinal wrapping of the shellV around the inner parts. A threaded opening 24v is' formed in the dome' 23, through which the After' the deliver;7 conorA welded tubing, is cnt to proper length, I preferably shape it in suitable dies to obtainr theY bends at `I2and I4 andthe elliptical shapeof thespout I3 an-d'delivery,oricer l5. is so shaped that it will t snugly within the hollowV interi-or of the longitudinal trough portion 22, of the shell 2i. The lower end of the vertical portion Iiir of the delivery conduit is then threaded s o that it can receive theconnection I 'I A fter the delivery conduit is properly shape-d 2 and threaded, I place the spout .I3 in the longi- Y tudinal trough portion 22 .of the shell 2|, and with,` these parts snugly fitting each other, I

22 of the shell so that their edges, 3 4 and 3 5 are almost injuxtaposition on. the undersideY of the horizontal spout I 3.0i the delivery conduit I0.

I then screw the guide bushingl I8;. outwardly through'thegthreaded opening 24 in the dome4 23,

andthe flanged end 28 of the clamping bushing 21,' isI positioned within and slightly `above the lower edgev ofl the dQme are deeper than .The smut-v 2 3, so` that the guide j bushing ,Ill` andsvertical portion IIofr the deliv.-

ery conduit extend through the clamping bushing.

With the different elements just described held in suitable devices, I fabricate the entire structure in a single welding operation. I unite the abutting edges of the trough portion 22 of the shell 2| at 36, as indicated in Figs. l and 2, from theY point 3'Iv at the delivery orifice I5 to the' point 38 atthe'lowenedge ofV the dome 23. I then continue the Welding operation by welding the clamping bushing 2l to the dome 23 at of a wash basin, a clamping bushing 2'I having 29, either tack welding or entirely welding the junction between the inner wall of the dome 23 and flange 28 of the clamping bushing 2l. The guide bushing I8 and vertical portion I6 of the delivery conduit are preferably tack welded to each other and to the clamping bushing at 3B and 3|., respectively., After the welding operation,` the welded parts may be finished off smoothly by grinding.

In viewaof` the foregoing, it will` be clear that Ihave provided asim-plied and improvedfabricated uid fixture construction.` The various fitting partsv Ycan be readily machined in any de-y sired in anner,A and` thel shell forming the nondetachable enclosing Astructure canY be readily made of pressed `sheet metal. fabricate the xt'ureelements by welding, the elements of the fixture can also b e readily fabricated togetherv by brazing or by any other suitart that modications may be made without dedescribed my in partingfrom the 'spirit and scope of my invenj tion.'
