Definitions

  • This invention comprises china or ceramic sanitary ware such as toilets, lavatories, bidets, and urinals ⁇ and similar articles which are made from materials having at least two contrasting colors and may be provided with an appearance resembling natural stone or marble.
  • the invention also includes the process and apparatus for making such articles. Two or more ceramic ware-forming slips of different colors are combined into a unitary stream but not completely blended when poured into the cavity ofa moisture-absorbing mold. Special pouring and filling techniques are employed to facilitate the approximate repetition of a design in the formed article for those who desire to be able to repeat a particular design.
  • pouring and blending may also be controlled so as to avoid initial contact between the unitary slip stream and the visible or marketing surface of the mold forming the finished product where a product of a particular ap pearance is desired. This results in a natural stone or marblelike appearance of the finished product, and the particular design can be generally repeated in subsequent articles.
  • Pouring may also be controlled so as to contact the marketing surface where such marbilized appearance is desired. For those who desire variation from product to product, this can be accomplished by varying color and slip compositions and by mold manipulation ⁇ PATENTEU .mn 1 ma 3,634,179 SHEU 01 0F 11 I g 1 u.
  • sanitary ware made from ceramic ware china such as lavatories, toilets, toilet tanks, urinals, bidets and other items of sanitary ware used in residential bathroom and public rest rooms were usually made in white colors, the color derived from a glaze coat applied to the body and the gloss achieved through the firing process.
  • slip was poured into plaster molds from the top until the mold cavity was filled, and after the desired wall thickness has been obtained, the excess liquid slip was drained from the mold.
  • An important object of this invention is to provide an improved article of vitrified sanitary ware, wherein the article has a natural stone or marble appearance and also the hardness of vitrified china.
  • a further object is to provide a mold having a cavity for forming a product of vitrified china or ceramic ware from poured slip, having a stone or marbleized surface, and from which the cast article can be removed, worked on, glazed and heat treated in a kiln, in the same manner as conventional articles of vitrified sanitary ware.
  • a further object of this invention is to provide for a process and method for making marbleized sanitary ware having the appearance of natural stone or marble.
  • Another object of this invention is to provide a method for effective veining of the slip cast clay body of vitrified sanitary ware.
  • Another object of this invention is to provide a new and improved method for the manufacture of ceramic and sanitary ware, which will permit a variety of design configurations to be made and which can be generally reproduced consistently.
  • a further object is to provide a new and improved method for making ceramic sanitary ware which will permit design configurations to be made different for each product by vary ing the color ratios and mixture of slip and by manipulating the mold, controlling the amount of colored slip and areas where the composite slip is introduced into the mold cavity.
  • a further object is to provide a water-absorbing mold for slip casting wherein multicolored slip is fed into predeter mined areas of the mold cavity to effect particular styles of veining.
  • a further object is to arrange a slip casting mold so as to enable a composite multicolor slip to be poured into the mold cavity against a cavity wall that does not form the marketable surface of the article and allows the marketable surface to gain initial contact with the multicolor slip as it rises in the mold cavity due to the continued pouring of the slip.
  • FIG. l shows a pair of water-absorbing plaster of paris molds having a cavity therein with the pouring funnels in place and the mold is partially filled with multicolor liquid slip.
  • FIG. 2 shows the mold after it has been completely filled with slip of two different colors, but prior to the excess slip being drained therefrom.
  • FIG. 3 shows partially dehydrated slip remaining in the mold after the excess liquid slip has been drained therefrom.
  • FIG. 4 is a top view showing the natural marble appearance of a ceramic basin formed by the apparatus and process shown in FIGS. l-3 wherein the pouring hole has been off set to one side of the lavatory.
  • FIG. 5 is a top view showing the natural marble appearance of the ceramic lavatory formed by the apparatus and process shown in FIGS. l-3 wherein the pouring hole has been centered relative to the sides of the lavatory.
  • FIG. 6 shows an alternative method for pouring two different color slips through the area which will form the waste opening of a lavatory to form a lavatory having a natural stone or marble appearance.
  • FIG. 7 shows the stone pattern achieved by pouring slips of two different colors in the manner shown in FIG. 6.
  • FIG. 8 shows a mold positioned at a tilted angle, so that slip can be poured into the mold without initially contacting the surface of the male mold member which will form the marketable surface of the finished lavatory.
  • FIG. 9 shows the natural marble pattern achieved by pouring slips of two or more different colors in the manner shown in FIG. 8.
  • FIG. l0 shows a mold cavity being filled with an incompletely blended multicolored slip through the drain hole of an inverted mold.
  • FIG. l1 shows the pattern resulting from a mold filled in the manner shown in FIG. l0.
  • the articles of chinaware I have used to illustrate the invention are lavatories which have a natural stone or marble appearance. Instead of lavatories, the mold could have been shaped to form toilets, bidets, tanks, urinals or other items of ceramic ware which today are made in solid colors.
  • FIG. l I have shown a pair of water-absorbing matched molds l0 and l2 for forming a lavatory wherein the veining will extend from one corner of the lavatory up on one side and across the basin and up the opposite side of the basin.
  • These molds have a cavity formed therein which is of the shape of the product to be formed. Molds of this type are well known in the slip casting art and are usually made from plaster of Paris.
  • the two molds are held together at their peripheral flanges 14 by suitable means such as C" clamps I6, or other similar holding means. These C clamps are opened and closed by a suitable clamp screw 17 in a manner well known in the art.
  • a suitable drain hole ll is provided to drain excess slip from the mold cavity.
  • a plastic plug 15 is inserted into the hole ll to plug the same when it is not desired to have slip drained from the hole l1.
  • the C" clamps are opened. This permits the female 10 and male l2 molds to be separated to release the molded article which is then in a state commonly known in the art as greenware. It is suiciently solidified to hold its shape, but soft enough to be readily deformable and cuttable by a knife or other suitable cutter.
  • the inverted female mold 10 is provided with an opening 18 adjacent the area of the lavatory which is to become the drain hole of the lavatory into which a funnel 20 is inserted.
  • One or more vent holes 22 are provided in the upper portion of the mold l0 to allow air to escape as the slip rises in the cavity 24.
  • a pouring hole 26, into which a tall funnel 38 is inserted is provided at the base of the inverted mold member l0 which will form the back edge. All initial pouring is effected through this funnel 38 to accomplish certain appearance affects in the final product as will be more fully explained hereinbelow.
  • the pouring hole can be off set to either side of the back ledge of the lavatory or it can be centered.
  • slips Two or more slips, either of different colors, or of neutral and colored slip are poured together from different suitable sources of supply. I have shown pouring pails 30 and 32 as being the sources of supply. The poured slip streams join physically together at the bottom mouth of the funnel 28 without effecting a uniform blending of the slips with each other.
  • the slips employed may be of the usual well known compositions employed for making ceramic sanitary ware.
  • a basic neutral slip composition which can be used for this purpose is:
  • Inorganic colors are added to one or more separate batches of said slip which are poured together in the manner shown in FIG. l so they join in a common stream but do not become uniformly blended with each other.
  • Such stains or pigments are obtainable on the operi market and are known as body or glaze stains, sold by various companies listed in trade directories and journals.
  • the amount of coloring that is added to a batch of slip has to be varied in accordance with the degree of color and contrast that is desired, in a manner similar to the way one adds color to paint.
  • the pails or containers 30 and 32 have been employed for purposes of illustration, other means such as pumps, metering valves, supply hoses, etc., could be used instead for feeding slips of different colors to the funnel 38.
  • the important factor is that there should be no uniform blending of the different colored slips taking place as a result of the feeding operation.
  • the slip By depositing the slip on the side of the mold which is opposite to the marketable surface, the slip will distribute itself horizontally and as it rises in the cavity the slip then first comes into contact with the marketable surface of the mold. This results in striations or veining which has depth in the body of the final finished product and will show up in a manner similar to the way veining is formed by nature in sedimentary rock so that the ceramic article appears to be made from natural stone or marble.
  • the combined slips deposited inside of the cavity 24 rise upwardly in the cavity 24 from the bottom of the cavity.
  • the first contact of the slip with the marketable surface 13 of the plaster mold l2 will be as the slip rises upwardly from the bottom and not by pouring the slip directly on the male mold.
  • FIG. 1 shows the slip rising in the mold cavity 24 and at this time the cavity is partially filled with slip.
  • the male portion l2 of the mold forms the finished marketable surface 13; that is, the surface of the finished product that will be permanently visible to the consumer.
  • the first contact of combined neutral and colored slip with the male mold member l2 will be as the slip arises upwardly in cavity 24 and not as it runs down the side of the mold surface.
  • the colored slip as it rises and as it moves horizontally in its initial contact with the marketable surface of the mold leaves streaks or striations, due to the stretching out of the colored slip as it moves in the mold cavity, thereby leaving striations of color along the mold surface.
  • the filling funnel 38 fits tightly in the hole 26 in which the funnel is positioned, so very little, if any, slip leaks out at this junction.
  • the cavity 24 has been completely filled with slip, as shown in FIG. 3, all cavity portions thereof will be filled and excess air will have escaped through the vent openings 22, and through the waste opening I8.
  • Water is absorbed from the poured slip by the walls of the plaster of paris molds l0 and l2. As such water is absorbed into the plaster of paris molds l0 and l2, the reserve slip in the funnels 20 and 38 descends to make up for this water removal. As the water is removed, the solids are drawn to the mold surface by the capillary action of the water migrating to the outer surface of the mold. In this manner, a build up of solids is effected on the mold walls which ultimately forms the green ware when the molds are separated to remove the formed article.
  • the slip is allowed to remain in the mold cavity 24 a length of time sufficient to permit the desired amount of water to be absorbed from the slip which results in walls of the article building up to the thickness desired.
  • the plug l5 is then removed from hole ll and the excess slip still remaining in a liquid form then runs out through the hole ll.
  • an overflow passageway 25 is formed, as shown in FIG. 3 which connects with the drain outlet 18.
  • a hole 27 is cut in the upper edge of the basin with a knife or cookie cutter, when the clay is firm enough to work, to form an overflow entrance from the basin into the overflow passageway, in a manner well known in the art.
  • the formed green ware shown in FIGS. 4 & 5 made from a composite slip of two different colorings, poured in the manner and with the apparatus shown in FIGS. l-3 has marble or stone like appearance such as shown in FIGS. 4 or S depending on the location of the pouring hole.
  • lt is also possible to vary the intensity of the contrasts by changing the amount of coloring in the colored slip and in the neutral slip.
  • a mixed slip 70 from two separate colored slip sources of supply 72 and 74 can be poured with the mold right side up, directly through the funnel 77 into the drain opening 76 formed in the male mold member 78 made from plaster of paris.
  • Conventional vent openings 80 and 82 are formed in the male mold member 78 to allow air in the mold cavity to escape as the poured slip rises in the cavity fills the same with multicolored slip.
  • the poured slip cornes into contact with the marketable surface 86 of the mold as it rises in the mold cavity.
  • the veining and striations will tend to extend from the drain opening and will radiate from this opening in concentric circles and will tend to be symmetrical on opposite sides of the article of sanitary ware. Excess slip is drained from the mold cavity in the manner previously described, by removing the plug 79.
  • FIG. 7 shows generally how the symmetrical striations and veining will appear when slip is poured in the manner just described.
  • slip is poured through the top edge of the mold while the male and female mold members are supported at an angle in a manner shown.
  • the simultaneous pouring ofthe several colored slips from pails 50 and 52 is effected through an opening 54 formed in the male mold member 56.
  • the male member 56 and female member 58 are held together by suitable C" clamps 60 and 62 in the same manner as shown in FIG, l.
  • Vent holes 64 and 66 are provided to allow excess air to escape from the mold cavity 68 when the pouring is being effected.
  • the embodiment shown in FIG. 8 shows how slip can be poured without depositing any of the poured slip mixed with the color slip directly on to the marketing surface of the mold member.
  • FIG. 9 shows the pattern of the final product after it has been removed from the mold shown in FIG. 8.
  • FIG. 10 shows how partially blended different colored slips can be poured from suitable sources of supply and 92 into the inverted mold through the drain opening 94.
  • Suitable vent holes 96 and 98 are provided to enable the mold cavity 100 to be completely filled with partially blended multicolored clip.
  • the plaster of Paris molds 102 and 104 are aligned with each other by means of dowel balls 106 and 108 and are held together by suitable clamps 110 and 112.
  • the poured material comes into contact initially with the marketable surface of the mold and runs down the sides of the male mold.
  • the pattern configuration shown in FIG. 1l will be obtained in this arrangement.
  • an additional head is also poured into the funnel l10a to provide for shrinkage due to water absorption. This keeps the mold cavity completely filled with slip, despite the shrinkage and permits the slip to remain in the mold for the amount of time required to allow the product walls to build up to the thickness desired.
  • the excess liquid slip is then drained from the mold by removing pin 101 from drain hole 103, thus leaving a hollow cavity in the finished article which can be used for the overflow.
  • suitable holes, for draining, overflow and fittings are then cut in the formed product.
  • the molded product which is then in a form known as green ware is then sent through a kiln for heat treatment of about 2,300 F. in a manner well known in the art to vitrify the same.
  • a kiln for heat treatment of about 2,300 F.
  • An article of ceramic sanitary ware as described in claim l comprising several partially blended slips of different colors, having vein structure resembling natural stone and a glazed finish on the finished sanitary ware article.
