Patented Oct, 1.4, 1930 PATENT I OFFICE JOSEPH BAB'IA, OF MARTIN'S FERRY, OHIO TUB Application filed August 14, 1929 Serial No. 385,730.

My invention relates to tubs, and more particularly to such tubs as are especially adapted for rinsing clothes, dishes, or other articles which have been previously washed.

When such articles are rinsed in a tub, the

water contained therein soon becomes contaminated with the dirty residual wash water from the articles Washed which results in the formation of a scum of dirt and grease on the top of the water and a corresponding decrease in the rinsing etliciency thereof.

According to the present invention, I prevent the rinsing water from thus losing its etticiency by the provision of means-for cone tinuously removing the scum from'the surface of the water while articles are being rinsedin the tub.

An object of the invention isto provide a tub with inlet means adjacent the bottom thereof for continuously introducing the water into the tub, and outlet means adjacent the top of and extending substantially around the tub 'for draining water therefrom at the same rate at which it enters, and at the same time efiectively removingthe scum from the top of the water. Other objects will become apparent from .a reading of the following description, the appended claims, and the two views illustrated in the drawings, in which:

Figure 1 is a top plan view of a tub embodying my invention; and

Figure 2 is a vertical sectional view taken on the line 2-2 of Figure 1.

In the drawing, whichillustrates a practical embodiment of my invention, there is shown a rinsing tub A, generally oval shaped in cross section and including a bottom 1, side walls 2, and end walls 3. The side and end walls are curved and merge with each other to form a continuous wall to be generall referred to throughout the remainder o the description and i'nthe claims as'a side wall. The bottom wall 1 is provided around its outer edge with a U-shaped seat. 4 in which the lower edge of the side wall is positioned, the side wall being secured in the seat 4 by solder, rivets, or other suitable means.

For reasons to be hereinafter set out in detail, it is desirable that means he provided for admitting water to the tub adjacent its bottom and for discharging or draining ofi water from the tub adjacent its top. To this end I provide inlet means generally designated B in the bottom of the tub and outlet means C adjacent the top thereof and extending around the side wall.

The inlet means B includes-a coupling 5 comprising a body portion 6 and a peripheral flange.7 adjacent but spaced from the upper end thereof. The upper end of the coupling is positioned in an opening 8 in the bottom of the tub, and the peripheral flange 7 is arranged to abut against'the bottom 1. Rivets 9 passing through the flange and the tub bottom serve to securely connect" the coupling 5 to the tub bottom 1, although the couplin 5 may be secured to the tub by other suita'le means such as solder. The coupling is hollow throughout its len h, thus providing an inlet opening 10 for t e tub and the lower end portion of the body 6 is exteriorly threaded to receive a hose'coupling 11 on a flexible water supply hose 12.

In some locations, it is often diflicult to procure rinsing water which is absolutely free from entrained dirt, and, in order that any such matter present in water flowing in through the hose 12 be prevented from entering the tub, Iprovide a strainer comprising a plug 13 having its lower or outer end portion threadably mounted within the coupling 5 and its upper or inner end portion extending into the tub, the plug having a longitudinal passage 14 extending inwardly from the outer end of the plugand open to the interior of the tub at the inner end of the plug, and a lateral passage 15 extending through the inner end of the plug and communicating with the assage 14 and with the interior of the tub. lhe inner end portion of the plug is substantially ball shaped, this ball shaped portion being disposed adjacent a flange 16 which abuts against the bottom of the tub when the plug is screwed into place. Intermediate the ball shaped end of the plug and the flange 16 is a recessed circumferential seat 17. A strainer cloth 18 is positioned over the inner end of the plug and over the seat 17 and is held in place by means of a string or wire 19 which passes around the cloth and the plug and, when drawn tight, binds the cloth in the seat 17. Any solid matter contained in the water entering through the hose 12 will be prevented from passing into the tub by means of the strainer-cloth, and if the amount of sediment in the water is great, so that the strainer cloth becomes-clogged up, the cloth may be readily removed for cleaning or replacement without its being necessary to empty the tub.

The means C for discharging water from the tub includes an outwardly curved portion 19 formed in the side wall and extending completely around the tube and a perforate ring 20 shaped to conform throughout its length to the inner face of the side wall and having an inwardly curved portion 21 spaced from the adjacent side wall portions to form a discharge conduit 22 which is fixed with relation to and which extends continuously around the side wall. The outwardly curved section 19 of the side walls is provided with an outlet, connection 23having flanges 23; se-

- cured to the section 19. The connection 23 is formed with a tubular threaded outer end to receive a hose coupling 24: on a flexible hose 25.

In order to provide a strong and durable connection between the side wall of the tub and the ring 20, the walls are formed with a seat extending completely around the tub and comprising spaced upper and lower aligned seat portions 26 and 27, respectively, which receive flanges 28 and 29 on the ring 20 extending respectively above and below the curved portion 21 thereof. The side wall of the tub is also provided with a pressed rib 30 upon which the lower edge of the flange 29 rests. The ring 20 is secured in position in the seat in the side wall by means of solder, rivets, or other suitable means.

In order to effect a continuous removal of the scum from all parts of the surface of the water it is necessary that all of the surface water be kept moving. To cause this movement of the entire surface of the water, a continuous or substantially continuous horizontal dischar e opening extending substantially around t e-tub must be provided, since, if only a single opening located at one point in the side wall is used, only that part of the surface water which is closed to the opening will be kept moving and the dirt and grease on other parts of the surface will form as a film which will adhere to the side Wall and consequently will not be removed from the tub. For this reason I provide the ring 20 with a series of spaced openings 31 of restricted area which are arranged in a common horizontal plane and which, as a series, extend substantially around the tub. When water is su lied to the tub continuously through t e iiose 12, it will finally reach a levei little above the bottom edges of the openings 81 and will then flow into the conduit 22, from which it will be drained through the hose 25. Since the openings 31 collectively extend all around the tub, water will drain from all points of the surface to the sides of the tub and will consequently keep the surface scum moving so that no film of scum will become lodged against the tub side wall. By using a series of individual 0 enings of restricted area, the velocity of t e water flowing towards the openings is greater than it would be if a single openin or slot extending completely around the tu were provided, and the scum will be effectively broken and will readily travel with the water out through the openings.

If water should be introduced into the tub at a rate somewhat greater than normal, the openings 31 might not present sutficient area to allow the water to drain off as fast as it enters. For this reason I provide the ring 20 with another series of spaced openings 32 extending substantially around the tub and disposed in a plane above the plane in which the openings 31 lie. In order to'avoid weakening of the ring 20 through the cutting of a multiplicity of openings therein, the openings of the lower series and the openings of the upper series are staggered with respect to one another. It is obvious that if water isadmitted to the tub more rapidly than it may flow out of the lower series of openings, it will rise until it reaches the upper series of openings, at which time the openings of the lower and upper series will together provide a discharge area suflicient to discharge wafoter at the same rate at which it enters the tu From the foregoing it will be apparent that a tub embodying my invention greatly simplifies the work of rinsing previously washed articles of various kinds. The rinsing operation may be completely erformed in a single tub which is always ull of clean water. When using my improved tub it is not necessary to empty the tub and refill it several times, as is the case with ordinary tubs.

I claim:

1. A tub comprising a side wall; a bottom; an inlet opening for said tub located adjacent the bottom thereof; a discharge conduit extending around said side wall adjacent the top of the tub and having an inner face forming a portion of said side wall; a lower series of spaced dischar e openings in the inner face of said conduit and extending substantially around the tub in a common plane; and an upper series of spaced-discharge openings in the inner face of said conduit and extending substantially around the tub in a common plane above the plane in which the lower series lies.

2. A. wash tub comprising a side wall; a bottom; means for admitting fluid to the tub adjacent the bottom thereof; a horizontally disposed recessed seat extending around the inner face of the side walls; and a ring shaped to conform to said inner face of said side wall and having spaced flanges positioned on said seat, said ring having a perforate intermediate portion spaced from the side wall of the tub and oonjointly forming therewith a conduit extending around the tub.

3. A tub comprising a side wall; a bottom; discharge means in said side wall adjacent the top of the tub and extending substantially around the tub; an inlet opening in the tub;

a plug having its outer end portion mounted in said opening and having its inner end portion extending into the tub; a passage in said plug extending inwardly from the outer end thereof and having an inner end arranged to communicate with the tub adjacent the bottom thereof, said plug being provided with a recessed seat located between the inner end of the passage and the outer end of the plug;
