LAVATORY.
Application filed August 9, 1924. Serial No. 731,121.
The present invention relates to lavatories, and more particularly to lavatories made of clay or other plastic material.
An important feature of this invention is the combination of a solid or single wall basin and a support at the back thereof for supporting the basin and preventing it from sagging when the lavatory structure is in the green state and during firing.
Another feature of the invention is the cast-in overflow at the back of the basin.
A. further feature of the invention is the provision of recesses and holes for the accommodation of fittings.
Additional features of the invention will be apparent from the following description:
In the drawings,
Figure 1 is a view partly in plan and partly in horizontal section of a preferred 20 form of lavatory embodying my invention;
Figure 2 is an inverted plan view of the lavatory;
Figure 3 is a vertical section on the line TTT-ITI of Figure 1;
Figure 4. is a sectional view of the lavatory on the line TVIV of Figure 3, and
Figure 5 is a vertical section on the line V-V of Figure 1.
The basin 2 of the lavatory from the apron i 8 down to the waste outlet 4 is formed solid except at the back thereof where a cast-in overflow passage 5 is provided. The bowl is surrounded by the usual horizontal ledge or slab 6 and extending vertically from the rear edge thereof is a back 7 having a thickened hollow rim 8. It will be apparent that the back 7 may or may not be provided. The apron 3 is also formed hollow.
The solid or single wall portion of the basin is produced by the method known in the art as double casting, that is to say, the walls of the plaster of Paris mold are placed close enough together to draw the moisture out of the clay so that the clay cast solid 4" between them. However, at the back of the basin the walls of the mold are placed at a distance apart such that the clay is left in a liquid state in the central portion of the molded wall and can be drawn out to form the outlet passage 5. This method of casting is what is known as single or hollow casting. In order to remove this liquid clay, the basin is tilted at an angle sufficient to insure proper drainage and an opening a is formed at an upper corner of the basin, and a drain opening d, as shown in Figure e of the draw ings is provided. Thereupon the liquid clay drains from all of the cavities to the drain opening. These holes a and (Z are then plugged up and the lavatoryis set on its back to dry from the green state and is afterward fired, still resting on its back.
In order to support the basin while being dried from the green state and also during firing I cast the lavatory with a supporting arm 9 at the central portion of the back wall of the basin. This supporting arm is flush with the back 7 and extends downwardly from said back and from the portion of the apron 3 at the rear of the lavatory. The lower end of the arm is in substantially the same horizontal plane as the lower surface of the basin at the waste outlet t. Formed in this supporting arm and opening out through the rear face thereof is a relatively large recess 10. Communicating with this recess are two aligned holes 11 and 12, the hole 11 extending through the ledge 6 at the rear of the basin and centrally thereof and the hole 12 extending through the lower portion of the arm 9. These holes are provided primarily for the reception of the operating rod for the usual pop-up valve for controlling the waste outlet 4. It will be noted that these holes are accessible from the back of the lavatory through the recess 10, this being an important feature in that it enables a plumber to readily obtain access to these holes for making his fittings. Extending through the ledge 6 at the back of the lavatory and at opposite sides of the supporting arm 9 are the usual cock-holes 13 and 14: for the hot and cold water pipes. These holes may be of uniform diameter throughout or may be tapered at one side as indicated respectively at 13 and 14 in the drawings to provide the desired play for the cock connections. The under surface of the lavatory is counter sunk around these holes for the reception of the fittings, as indicated by the reference numeral 15. Transverse openings 16 extend through the supporting arm 9 and communicate with the recess 10 and with the counter sunk recesses 15. When a universal fitting is used, the pipe for the-common cold and hot water spigot comes up through the hole 12 and the holes 16 are utilized for the passage of the operating mechanism from the hot and cold water buttons to the valve which is located in the recess 10. These hot and cold water buttons project up through the cock-holes l3 and 14;?
idling.
The waste outlet 4 and the holes 16 in the supporting arm 9 and the hole 171 leading from the basin to the overflow passage 5 are cut when the clay is green. The cock-holes 13 and 14L however are formed bycoresi in the mold.
It has heretofore been customary in the art to attempt to support the lavatory during firing by the use of a separate-prop or block. This, however, has not been satisfactory, while the integral support or arm 8 forms an efiicient support facilitating hanlVhileI have shown and described a preferred embodiment of my invention, it will be understood that changes may be made in thedetails of construction without departing fromthe spirit of tlreyinvention or scope of the appended claims.
