MAXIMILLIAN W. WUES'II-IOFF, OFHSAN FRANCISCO, CALIFORNIA.
Application filed February 18, 1925.
T 0 all whom it may concern:
Be it known that I, MAXIMILLIAN 1V.
VVUnsrriorr, a citizen of the United States, residing at the city and county of San Francisco and State of California, have invented new and useful Improvements in Vaterspouts, of which the following is a specification. This invention relates to connections for water spouts or taps, and more particula ly to a connection for the china or porcelain spouts used in connectionrwith bath tubs and the like.
IIeretofore there has been difficulty in )ro oerl connectin ceramic s outs to the water pipes, owing to the fact that threads can not be formed directly on the ceramic spout, and any metal sleeve or bushing fitted tightly into the china or porcelain spout is liable to cause cracking, due to unequal expansion of the different ma.- terials, which condition is aggravated where the same spout is used for both hot and cold water.
In and by the present invention I overcome this ditliculty by providing a threaded metal sleeve fitted loosely in the porcelain spout and having means for preventing turning of the sleeve, while permitting endwise movement thereof.- This sleeve bears at its inner end against a rubber packing ring carried within the spout and surrounding the water pipe to which the spout is to be connected. IVhen the sleeve is threaded on to the end of the water pipe it is drawn tightly against the packing member, and this packing member in turn forces the spout tightly against the wall, and at the same time forms a watertight connection between the water pipe and the inner end of the spout.-
One form which my invention may assume is exemplified in the following description and illustrated in the accompanying drawing, in which Fig. 1 shows a vertical sectional view of a spout embodying my invention, in position upon a water pipe and seated against a Wall;
Fig. 2 shows a cross section taken on the line 22 of Fig. 1;
Fig. 3 shows a perspective view of a spout embodying my invention, and a bathtub associated therewith.
lvIerely by way of illustrating one application of my invention, I show a bath tub Serial No. 9,965.
10 and a single spout 11 for supplying both hot and cold water to the tub. Of course there may be separate spouts for the hot and cold water, but the more modern practice is as shown in the drawing. This spout is formed of china or porcelain to harmonize with the rest of the bath room, and in practice is seated against a wall 12, a slight distance above the tub.
Inside of the spout I arrange a metal sleeve 13 which is of smaller diameter than the bore of the spout, thus leaving a considerable space between to allow for unequal expansion and contraction of. the spout and sleeve. To prevent turning of the sleeve within the spout, while at the same time permitting endwise movement, I provide keys 14 on the sleeve, fitted into keyways formed on the interior of the spout. The metal sleeve 13 is threaded interiorly and is adapted to connect with a water supply pipe 15.
The inner end of the spout is enlarged and has an inturned flange 16 to seat against the wall 12. Between the inner end of the sleeve and the flange 16, and surrounding the water pipe 15, is a rubber gasket or packing member17. In operation the sleeve is inserted in the spout and thereafter the rubber packing member is put in place. Then the spout and rubber gasket are slipped over the end of the water pipe, and the sleeve is threaded into the end of said pipe by turning the spout. The spout will thereby be clamped securely against the wall by pressure of the sleeve upon the rubber gasket, which gasket in turn bears upon the flange 16. The gasket when compressed will. form a water-tight fitting between the pipe 15 and the inner end of the spout.
From the foregoing it will be seen that I have provided a simple and inexpensive connection for a china or porcelain spout, which connection is water-tight and provides for unequal expansion and contraction of the ceramic spout and the metallic sleeve.
Various changes in the construction and arrangement of the several parts may be employed without departing from the spirit of my invention as disclosed in the ap pended claims.
What I claim as new and desire to secure by Letters Patent is:
1. The combination with a metallic supply pipe of a ceramic spout for co-operation therewith, a metallic sleeve fitted slidably but non-rotatablyin said spout, said sleeve being threaded for connection with the supply pipe, and a rubber packing member surrounding said supply pipe and lying between the inner end of the spout and the adjacent end of said sleeve.
2. The combination with a metallic supply pipe of a ceramic spout for co-operation therewith, said spout having an enlarged inner end formed with an inturned flange to seat against a supporting wall, a
metallic sleeve of smaller diameterthan the spout, fitted slidably but non-rotatably therein, and threaded interiorly for connection with the supply pipe, and a rubber packing member surrounding the supply pipe and having an enlarged head portion lying between the sleeve and the inturned flange at the base of the spout.
3. The combination'with a metallic supply pipe of a ceramic spout for co-operation therewith, said spout being formed with an inturned flange at its base, adapted to seat against a supporting surface, a sleeve of smallerdiameter than the bore of the spout, formed with keys fitted in keyways on the spout, and a rubber packing member surrounding the supply pipe and having a portion lying between the flange at the base of the spout and the sleeve, said sleeve and supply pipe being threaded for connection with each other.
