3 Claims. 1

This invention relates to improvements in sink fixtures, and has to do primarily with means for mounting a swinging spout in such a fixture.

One of the objects of the invention is the provision of such mounting means adapted for assembly without the use of tools.

Another object is the provision of such a mounting which is devoid of any visible fastening, and therefore presents a clean and attractive appearance.

Still another object is the provision of a mounting embodying both a snap ring and a gasket, the arrangement of parts being such that when the snap ring is forced into place for retaining the swinging spout in the body of the fixture, it causes pressure to be exerted on the resilient gasket for compressing the latter to effect good sealing contact with the relatively rotatable parts, and enabling the gasket to take up any looseness lengthwise of the joint which might otherwise be present.

Other objects and features of novelty will appear as I proceed with the description of that embodiment of the invention which, for the purposes of the present application, I have illustrated in the accompanying drawing, in which Fig. l is a fragmental elevational view, partly in vertical section, of a sink fixture embodying the invention.

Fig. 2 is a sectional view at right angles to the section of Fig. 1, showing the spout only.

Fig. 3 is a sectional view in the same plane with that of Fig. 2, showing only the body of the fixture, and

Figure 4 is a detail view of a spring ring employed in connection with the invention.

In the drawing a fragment of the central part of the body of a sink fixture is shown at IU, hav-- ing hot and cold water intakes II and I2. In. the middle of the upper wall [3 the body of the fixture comprises an upwardly opening cup l4, through the bottom of which there is an axial opening 15. An annular ledge i6 is thus provided at the bottom of the cup I4. This ledge is utilized for the support of a resilient gasket or packing ring I! which, in its original uncompressed condition, extends radially inward slightly further than the wall of opening l5, as indicated in Fig. 3. The cup l4 somewhat above the level of gasket I? has a groove I8 cut therein, and the upper internal edge of the cup is preferably beveled, as indicated at I9.

20 is a spout which is adapted to swing through a limited arc. It is provided with a depending trunnion having an upper relatively large diameter portion 2i and a lower small diameter portion 22, with an annular shoulder 23 at their juncture. In the large diameter portion there is formed an annular groove 24 that has a depth approximately twice its width. The smaller portion 22 of the trunnion has a rotary fit in the opening l5, and is of slightly greater diameter than the natural internal diameter of gasket [1, so that when the trunnion is forced down into its assembled position it compresses the gasket ll radially and tends to expand it lengthwise of the joint. The bore 25 of the trunnion is open at all times and serves as a connecting water passage between the intakes H and I2 and the interior of spout 20.

A split spring ring 26, preferably of circular cross-section, may be expanded sufficiently to enable it to be forced over the large diameter portion 2| of the trunion and into the groove 25. Its cross-sectional size is such as to cause it to fit snugly within the side walls of that'groove. In the assembled condition of the fixture approximately one-half of the cross-section of the ring stands within the groove and the other half projects therefrom. The groove is deep enough however to accommodate the full cross-section of the ring when the latter is compressed during the act of mounting the spout in the body. Groove l8 in the body however is just deep enough to accommodate half or approximately half of the cross-section of the ring. The width of groove I8 is of course the same as that of groove 24, and the two grooves match up or register in the assembled condition of the fixture.

In assembling the parts the workman first places gasket I! in the body 14, causing the gasket to engage shoulder It. Then the ring 26 is mounted in groove 24 of the spout, after which the trunnion 2|, 22 is pushed part way down into the cup N, that is until the ring 26 engages the beveled edge 19 at the rim of the cup. In getting the trunnion into this position the small diameter portion 22 will have been pushed through the gasket I! and at least part Way through the opening l5 at the bottom of the cup. Bevel 19 tends to center the ring 26. The operator then strikes a light blow with his hand against the top of the spout in line with the trunnion, which causes the ring 26 to be cammed inwardly into the deep groove 24 so as to pass the interior wall of the cup above groove l8 and down into register with the latter groove, whereupon the ring snaps outward again into the position illustrated in Fig. 1. By this action the gasket [1 which has already been compressed radially is also compressed lengthwise of lthe joint, and when the spring ring snaps into position to lock the spout to the body it serves also to hold the gasket I"! in its compressed condition, efiectively sealing the rotary joint against leakage. The mounting of the spout is thus effected Very quickly and easily without the use of tools, and a fixture of neat appearance without visible fastenings results. Whemthe =tru1mion is oscillated backgand forth its action is smooth, since theresilient gasket ll, acting upwardly against shoulder 23, takes up whatever slight looseness lengthwise of the joint might otherwise develop because of manufacturing tolerances or because of wear.

While I have described the ,cup 1'4 as formed in the upper Wall of body I and opening upward- 1y, it will be obvious that it could equally well be made a part of the lower wall, opening'downwardly. In other words the fixture :would be equally effective if the structure shown in the drawing were inverted, .and the claims should -besso construed.

Havingzthusdescribedtmyinvention, I claim:
