JAMES HARTNESS, OF SPRINGFIELD, VERMONT.

WASHBASIN.

To all whom it may concern.'

Be it known that I, JAMES Han'rnnss, of Springfield, in the county of IVindsor and State of Vermont, have invented certain new and useful Improvements in `Wash basins, of which the following is a specilication.

This invention has relation to wash basins, bath tubs, sinks and the like, and more particularly to overflow and discharge contrivances or devices therefor.

In my copending application Serial No. 338,866, tiled April 18, 1907, I have described and claimed an overflow and discharge device which includes, between the main trap and the basin, an intermediate air-containing trap or chamber, the two traps being so related that a column of water may be maintained in the bowl at a height above the water in the intermediate trap equal to the difference in level of the Water in the two columns of the main trap, by trapping a column of air in the inlet limb of the main trap. In the intermediate trap there is a stand-pipe which forms the outlet limb thereof, and which may be raised so as to permit the flow of water directly from the bottom of the intermediate trap into the main trap, so that the contents of the bowl will be discharged. The wall of the stand-pipe forms as it were a dam for preventing the outflow of water from the intermediate chamber so that, in this case, the raising of the stand-pipe is equivalent to lifting a gate at the foot of the dam.

The present invention has for its object to provide certain improvements in such overflow and discharge devices referred to.

I employ, as in the previous case, an intermediate trap or air chamber, but instead of using a stand-pipe as the discl'xarge limb of said trap, I employ a member which constitutes a dam whose lip or overflow point may be raised and lowered. In the embodiment ot' the invention illustrated upon the drawings, this dam consists of a rocking member which forms a discharge limb from which there is a port leading to the inlet limb of the main trap. This rocking member is shown in the form of a cup which has rotatable connec tion with the duct or conduit leading to the main trap, and it may be rocked by a lever from a position where it traps the air in the intermediate trap, to a position where Specification of Letters Patent.

Serial No. 376,077.

it permits a free flow of water from the intermediate trap into the main trap.

Referring to the accompanying drawings,-Figure 1 illustrates a wash basin equipped with my invention. Fig. 9. represents a longitudinal section through the same on the line Q-Q of Fig. 1. Fig. 3 represents a section on the line 3-8 of Fig. 2 and shows the cup in the intermediate trap in its upright position. Fig. 4 represents a similar section and shows the cup in its discharging position. Fig. 5 represents a section on the line 5-5 of Fig. 3. Fig. 6 represents a perspective view of the cup and the handle by which is is rocked. Fig. 7 represents another embodiment of the invention. Fig. S represents an enlarged section on the line S-S of Fig. 7. Fig. 9 represents an enlarged section on the line 9 9 of Fig. 7.

Referring lirst to Figs. 1 to (3 inclusive, a basin is illustrated comprising a bowl a. This bowl has a substantially vertical rear wall (1f, and a downwardly and rearwardly inclined curved bottom wall at', there being an elongated port a at the 'junction of the rear wall a of the bottom wall au. The basin is illustrated as being formed of enameled or porcelain-lined metal and has the usual apron at. Formed on the exterior of the rear wall a', there is an interniediate chamber or trap b, as shown in Figs. 1, 3 and 5. This chamber has top and bottom walls b b2, the side walls Li; L, and its front wall is formed by the rear wall L of the basin. rlhe rear wall 7) is formed with an aperture L for a purpose to be explained. c indicates the main trap which may be of any convenient form provided it has certain proportions hereinafter stated. The main trap, illustrated in Fig. 2, has the inlet limb c and the outlet limb c. These limbs consist of pipe sections which are screwed into the upper end of a closed casing c having a clean-out plug c4. Screwed upon the upper end of the discharge limb c is a union or fitting .c5 having a vent c and having a discharge port c?, which may be connected with the drainage pipe of the house. Secured to the upper end of the inlet limb o, there is a fitting es having a quarter bend as shown. This fitting is clamped to the rear face of the intermediate trap by suitable bolt clamps indicated at cf). Located in the chamber of the intermediate trap is va member forming the discharge limb of said intermediate trap, said member being shown as a cup d. The cup, in this instance, is formed with ar laterally projecting hollow hub or trunnion d which is journaled in the fitting es, and there is connected to the cup a handle or lever d2, by which it may be rocked from the position shown in Fig. 3 to the position shown in Fig. 4, or vice versa. This handle cl2 is shown as projecting through the discharge port as of the basin and extending upwardly therefrom so that it may be conveniently operated. The precise shape of the cup is quite immaterial, since itforms as it were, a tilting dam to stop the flow of water through the outlet from the intermediate trap or chamber, and any other member which performs the same function may be used in lieu thereof. As illustrated, the cup, so far as its general shape is concerned, somewhat resembles a miniature domestic coal hod.

The operation of the device is as follows Assuming that water is standing in the main trap c, at the height indicated by the dotted lines a; and that the cup or discharge limb of the intermediate trap is in the position shown in Figs. 1 and 8 when water is admitted to the bowl, the water flows from the bowl through the port t3 into the intermediate trap or air chamber, and, when the level ofthe water reaches the top lip of port a3, the air in the chamber is trapped; then as the water rises in the intermediate chamber, air is forced outwardly through the port Z3 in the hollow trunnion cl into the inlet limb c of the main trap o. This depresses the column of water in the inlet c and raises it in the limb c2. As the water continues to flow into the bowl, the height of the column of water in the bowl increases until it reaches its maximum height, which, measured above the level of the water in the intermediate trap, is equal to the difference in levelof the water'in the inlet limb c and the outlet limb c2 of the main trap. In Fig. 2 the water is shown at its maximum height in the bowl. Should water continue to flow into the bowl it will not overflow therefrom, since it will pass out through the intermediate trap and through the discharge limb or cup therein. If water be delivered to the bowl in large quantities at this time, it will tend to drive the air out of the limb c, through limb c2, and efl'ect a rapid discharge of the water. The water may be discharged from t-he bowl, however, by swinging the lever Z2 to the left in Fig. l so as to tilt the cup to the position shown in Fig. 4, so that the water may flow directly outward through the port (Z3.

llhere the discharge device is to be employed in connection with a staple bowl or a bowl of the usual shape, it may be constructed as shown in Figs. 7 to 9.- In this case, the bowl e has a centrally arranged discharge port through which extends a thimble e. Below the basin is the intermediate trap or air chamber f, which is illustrated as being cast integrally with the main trap g, said main trap having the inlet limbs g g2 respectively, with a clean-out as at g3. The cup h which is substantially similar to that shown in Fig. 6, has a lateral port 71, extending into a lateral annular flange which is journaled in the lateral mouth of the inlet limb g of the main trap. There is an opening in the side of' the intermediate trap h which is closed by a cap t'. A spindle z" passes through said cap and has a squared end entering a square socket in the side of the cup t. In the end of the spindle there is a pin 3 and a spring 2, which forces said pin against the side of the cup so as to hold its lateral flange ft2 against its seat in the mouth of the inlet limb g. Connected to the outer end of the spindle there is a lever y' to the end of which is loosely pivoted a rod j which extends upwardly through the apron of the basin, and is provided with a knob jz by which it may be raised and lowered. The operation of this discharge device is similar to that already described in connection with Figs. 1 to 6 and need not be explained in detail. In both of these embodiments of the invention there is in connection with the bowl and the main trap, an intermediate air-containing trap or chamber with a discharge limb formed by a dam whose lip may be raised or lowered, and a port leading from said limb to the inlet limb of the main trap.

It is quite evident that a variety of changes may be made in the construction of the device without departing from the spirit and scope of the invention, and in this case I desire to have it understood that the phraseology which I employ is merely for the purpose of description and not of limitation.

I-Iaving thus explained the nature of my said invention and described a way of constructing and using the same, although without attemptingto set forth all of' the forms in which it may be made, or all of the modes of' its use, I declare that what I claim is l. The combination vwith a bowl and a main trap,of afixed intermediate air chamber, a dam in said chamber forming a discharge limb communicating with said trap, and means for raising and lowering the lip of the dam to trap the air in said chamber or permit the flow of water over said lip through said discharge limb.

2. The combination with a bowl and a main trap, of a fixed intermediate air chamber, a rocking member in said chamber having a port communicating with the inlet end of said trap, and a lever connected to said member to rock it.

3. The combination with a bowl and a main trap, of a fixed intermediate air cham ber having a trap member which forms the outlet limb thereof, said trap member being provided with a lip, said limb having a port communicating with the inlet limb of the main trap, and means for moving the lip of said trap member.

4. The combination with a bowl and a main trap whose outlet limb is of a length to receive a column of water equal to the desired maximum column of water in the bowl, of a fixed intermediate air chamber which constitutes a trap, the inlet of said chamber communicating with said bowl, a member constituting the outlet limb of said intermediate chamber which communicates with the inlet limb of the main trap, and means for rocking said member from a posil tion where it traps water in said chamber to a position where it permits a free flow of water thereover from said chamber.

5. The combination with a bowl and a main trap, of an intermediate immovable air chamber, a cup-like member in said chamber having a discharge port communieating with said trap, means for mounting said member to move about an axis passing through said port, and means for rocking said member about said axis.

In testimony whereof I have affixed my signature, in presence of t-wo witnesses.
