WILLARD A. SPEAKMAN, OF WILMINGTON, DELAWARE.

LAVATORY-FITTING.

Application filed May 7, 1914.

To all whom it may concern Be it known that I, WILLARD A. SPEAK- MAN, a citizen of the United States of America, residing in Wilmington, in the county of New Castle and State of Delaware, have invented certain new and useful Improvements in Lavatory-Fittings, of which the following is a true and exact description, reference being had to the accompanying drawings, which form a part thereof.

My present invention consists in an improved fitting especially devised and adapted to be inserted in an aperture in a lavatory basin slab, and formed with a passage adapted to receive a tubular waste valve, and with a mixing chamber for hot and cold water and with a delivery spout opening therefrom above the basin slab when the fitting is in place, and having provisions by which hot and cold water supply pipes may be secured to the fitting in communication with said mixing chamber beneath the basin slab.

The object of my invention, considered in one of its aspects, is to provide a simple and compact fitting of the character specified above, which is adapted to be inserted in a basin slab orifice not greatly exceeding in diameter the diameter of the tubular waste valve passage provided in the fitting.

More specifically, the object of my invention is to provide a satisfactory fitting of the general character specified, characterized by the comparative simplicity of, and ease in forming the separate parts thereof, and having a waste valve passage adapted to receive a tubular waste valve of the usual size, while the fitting as a whole is of such size and form that it may be inserted in the central aperture of a standard form of basin slab having three apertures of the size, shape and arrangement commonly employed with separate hot and cold water supply valves mounted in the side apertures and each provided with an independent discharge spout located above the basin slab, and with the central aperture receiving a fitting, the sole purpose of which is to provide a suitable housing for a tubular waste valve. My improved combination mixing nozzle and waste valve fitting thus permits a standard basin slab to be fitted without any change in the slab structure with two different types of fittings, and thereby permits plumbers and plumbing supply houses to reduce the amount of stock kept on hand without correspondingly di- Specification of Letters Patent.

minishing the different styles of apparatus.

The various features of novelty characterizing my invention are pointed out with particularity in the claims annexed to and forming a part of this specification. For a better understamling of the invention, however, and of the advantages possessed by it, reference should be had to the accompanying drawings and descriptive matter in which I have illustrated and described one form in which my invention may be embodied.

Of the drawings: Figure 1 is a plan of a basin slab equipped with my improved fitting; Fig. 2 is an elevation, partly in section on the line 22 of Fig. l; and Fig. 3 is a plan of the improved fitting.

In the drawings, A represents the slab and A the bowl of a lavatory basin of common form. This slab is provided with a central orifice A and two side orifices. The cold water supply valve E is mounted in one of the side apertures and the hot water supply valve E is mounted in the other aperture. The discharge pipes D leading from these valves are located below the basin slab and communicate with the mixing chamber 13 of the central fitting 13 mounted in the slab aperture A. The fitting B comprises an annular head portion B located above the basin slab and provided with a delivery spout B" projecting from its peripheral edge. Connected to the head B and projecting from the lower end thereof is the mixing chamber containing part 13 The mixing chamber B in the part B communicates at its upper end with the passage in the spout 13*, and the part B is bifurcated atits lower end, the bifurcations terminating in threaded bosses B The delivery pipes D from the valves E and E are connected to the bosses B A tubular part B having its upper portion externally threaded is screwed into the head B, which is internally threaded for this purpose. The fitting is secured in place by means of a nut C threaded onto the upper threaded portion of the tubular part B, and the spacing member or elongated washer C interposed between the nut C and the under side of the basin slab A. The washer C is cut away to clear the part B and the bifurcated ends thereof, which curve about the part B, as shown best in Fig. 3. The tubular part B is connected at its lower end to a casing B". The latter is connected by the lateral pipe B to the waste outlet A in the bottom of the basin bowl A, and the lot casing member B is formed with a port in its lower end communicating with the waste pipe G. At the upper end of this port there is formed a seat 13 for a tubular waste valve F, which passes upward through the tubular part B and is provided with the usual head F above the fitting head B. Vith the valve F engaging its seat B the maximum height of water level in the basin bowl is fixed by the height of the overflow ports F in the tubular waste valve F.

It will be apparent to those skilled in the art that the construction disclosed is simple, and relatively easy to make, and is effective for the purpose for which it was designed. The fitting may readily be, and in practice is so proportioned that the part B may be passed through an orifice A of the usual size provided in standard basin slabs primarily designed to receive a simple tubular waste valve fitting, while at the same time the tubular body B is as large as is required to receive a tubular waste valve F of the usual size, and the mixing chamber B in the member B is of ample capacity. The construction is advantageously simplified by having the upper vertical portion of the part B connected directly to the discharge spout 13*, while the curvature given to the bifurcations of the part B not only induces the bulk of the apparatus and thereby makes it possible to pass the part B through a hole A relatively smaller than would otherwise be re quired,'but facilitates the connection of the pipes D to the free ends of these bifurcations.

Having now described my invention, What I claim as new and desire to secure by Letters Patent, is:

l. A fitting adapted to be mountedin an aperture formed in a basin slab or like sup-- port and comprising an annular head internally threaded and having a delivery spout extending from the outeredge of said annular head, a mixing chamber containing part extending from one end of said head adjacent said spout and formed with a chamber therein open at its upper end to said spout, and a tubular part having an externally threaded end screwed into the internally threaded head and adapted to receive a clamping nut, said mixing chamber containing part being flattened adjacent said head, and being formed with lateral oppositely disposed extensions having provisions for securing a pipe to each extension, and curved to fit snugly about said tubular part whereby the fitting canbe mounted in an aperture but slightly larger in diameter than said tubular part and when the latter is detached from said head the mixture containing part thereof may be withdrawn from said aperture.

QVThe combination with an apertured basin slab or like support, of a combination mixing nozzle and waste valve fitting comprising an annular head lying above the fitting with a discharge nozzle spout project ing from the peripheral edge thereof, a tubular part detachably secured to said annular head and forming a housing for a tubular waste valve, a mixing chamber containing part connected at its upper end to said head adjacent said spout and communicating with said spout and extending downward along side of said tubular part through the said aperture and having integral portions at its lower end oppositely curved closely about said tubular part and terminatingin bosses with provisions for connecting hot and cold water supply pipes thereto, a nut threaded on said tubular part below said mixture containing part and an elongated Washer extending between said nut and the under side of said support, and cut away at one side to clear said mixing chamber containing part.
