J'OSEPH H. NEAL, OF BALTIMORE, MARYLAND.
Specification of Letters I Patent. Pang-need June 21, 1916..
1 Application filed January 12, 1910. Serial No. 537,588.
To all whom it'may concern:
Be it known that I, JosErH H. NEAL, a citizen of the United States, residingat Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Bath-Tubs, ofwhich the following is a specification.
This invention relates to cast-metal bathtubs.
One object of my invention is to provide bath tubs with an improved top-roll having therein a water-conduit that shallbe formed in the foundry operations of molding and casting, by the use of a sand-corethe said water-conduit to have such novel structural features as will enable the said sand-core to be readily broken up and removed after the casting operations have been completed.-
Another object of the invention is to rovide a bath-tub with a top-roll water-con uit which will receive its supply of water at the front end of the tub-and said conduit to have such featuresv that the water will flow through the conduit from the said point of supply along both sides of the top-roll without dlscharging, until it has passed the median line between the front and rear ends of the tub, and then such water while it continues to flow after passing said median line shall freely discharge from the conduit and run down the inner surface of the wall at the rear part of the sides and at the end of the tub.
Another object of the invention is to provide a cast-metal bath-tub with a seat formed at one end of the tub and of metal integral with the tub structure, and also to provide the top-roll ofthe tub with a water-conduit that shall discharge water into the tub only at that part which is at the sides or around the said seat.
Another object of the invention is to provide a bath-tub with a top-roll water-conduit and to also provide the tub at its front end with a water-receiving chamber which shall be in communication with said waterconduit, whereby the water supply coming from the pipes under ressure will first enter the said chamber w ere the force of the water will be broken, and then flow from the chamber into the said conduit.
The invention is illustrated in the accompanying drawing in which,
. Figure 1 is a perspective side and top view of the improved bath-tub. Fig. 2 shows on a larger scale, a vertical cross-secto flow, but will also tion taken on the line 22, of Fig. 1, showing the top-roll and the water-receiving chamber. Fig. 3 shows a cross-section of the top-roll and water-conduit, taken on the line 33. Fig. 4 shows a similar section taken on the line H, over the seat.
In making porcelain enameled bath-tubs, the tub is first made of cast-iron in the foundry and is then enameled. Tubs of the class to which this invention relates are made and enameled as just mentioned.
In this invention the top-roll, C, is of special formation in order to produce a waterconduit, 6, havin the desired structural features. The bat -tub, A, the conduit, 6, and the roll, C, are all integral cast-iron. In molding the top-roll at the foundry to form the conduit, 1), a sand-core is used and in order to provide for the removal of the sand-core a slot, 03, is formed along the inward side of the roll, C, and at the top of the wall, 6, of the bath-tub. This open slot extends entirely around the top of the bath-tub except at the front end. It will be seen by reference to Figs. 1, 3 and A of the drawin that in forming the slot the contour an shape of the upper surface of the top-roll is preserved or may be shaped as preferred and the efiect of the slot, 05, is to produce on the top roll a lip, 7, that projects toward the interior of the tub, but stops short of a vertical line coincident with the inner surface of the tub-walls. For one half of the length of the conduit said lip is directly over a raised edge, g, shown in Fig. 3, at the top of the bath-tub wall, e. The top-roll thus made serves all the purposes and advantages which is served by the ordinary top-roll used on other tubs, and in addition this improved roll with its conduit, 6, and open-slot, at, will permit of the sand-core belng readily removed, will allow the porcelain enamel to be a plied within and will also provide for the ow of water in the conduit as 'far along as said raised edge, g, extends which is from the front end to a little past a vertical median line, indicated by the letter, 00. From the point indicated to the rear end of the tub the conduit is without the raised edge, 9, and the shape of the edge at this part 1s like that shown at, h, in Fig. 4. B'y-this construction the water after flowing ast the raised edge, 9, at oint, :23, will continue eely discharge along the lower edge, h, of the conduit and run down the inner surface of the wall, e, at the rear part of the sides and at the rear end.
In the vertical direction the tub is deeper at the front end than at the rear end, as seen in Fig. 1. The deepest part of the tub is at the lowermost horizontal bottom line, i; this dee est part has a rear vertical wall, k, which is in vertical alinement with the median line just forward of said point, :0. The shallow part of the tub is at the uppermost horizontal bottom line, y. This construction forms inside of the tub a seat which is indicated just above the line, j. The so-called seat will be of cast metal integral with the tub structure and comprises the entire high part of the tub-bottom at the rear end. The relative position of this seat with respect to that part of the water-conduit that has the low edge, h, is such that the water will discharge from the conduit and flow down the side and end walls, 0, around said seat. By using hot water the walls and seat will be made warm. A person can sit on the seat above high part, 9', and place his feet in the deeper part at '21.
A pedestal or standard, Z, is under the rear end of the tub and supports the same.
At its front end the tub has a water-receiving chamber, m, formed integral with the front-end wall, 6, of the tub; this chamber is constructed with its lower end open in order to remove the sand-core that must be used in molding the chamber. A plate, a, closes said lower end.
A surface, C, same as the top-roll covers theupper end of the water-receiving chamber and below this top surface said chamber has at opposite sides, a suitable opening, p, see Fig. 2, and said openings communicate with the water-conduit, b. The pipe or pipes, g, which lead from the watersupply, enter the said water-receiving chamber. The water from these pipes, g, is usually under considerable pressure, and as the water must first enter the chamber, m, the force of the water will be broken'or lessened, and then with a reduced pressure the water will flow from the chamber, m, into the conduit, b, of the bathtub. The waste or discharge of water from the tub takes place through pipe, 1'.
Bath tubs of cast-metal are usually if not always coated with vitreous enamel, and therefore the structural features of this tub have all been designed with reference to the practicability of the parts being enameled.
Having thus described my inventionwhat I eulaim and desire to secure by Letters Paten 1s,
1. A cast-iron bath-tub having a 110110 top-roll that contains a water-conduit which has directly over the wall of the tub an edge, 9, higher than the bottom of said conduit said higher edge confining the water to the conduit and extending from the 'front end of the tub to a median line between the said front and rear ends, and which conduit from said median line and extending to the rear end of the tub has a low edge, h, which permits the Water in the conduit to run down the inner surface of the tub-wall. I
2. A cast-metal bath-tub whose bottom is divided into two distinct parts-the frontend part being in a lower horizontal plane than the rear-end part which latter being higher serves as a seat, in combinationwith a hollow top-roll that contains a water-conduit provided with an open slot along the inward side of the roll-said conduit having a raised edge, 9, which confines the water to the conduit and extends from the front-end of the tub back to a point above the front of said seat, the conduit from said seat back to the rear-end of the tub having a low edge, it, which permits the water to'flow from the conduit down the sides of the wallsaround and onto the seat.
3. A cast-metal bath-tub provided wlth a seat at the rear-end of the tub-said seat b'eing integral with the metal of the tub, and also provided with a top-roll water-conduit which receives the water-supply at the front I JOSEPH H. NEAL.
