Definitions
- the present invention relates to improved extruding, glazing and firing of clay or ceramic elements. More particularly, the present invention relates to an improved ceramic element which can be extruded, glazed and fired without damaging the outer surface thereof.
- Clay or ceramic elements have been fired in a kiln by passing therealong on rollers.
- One side of such clay or ceramic elements has production marks interfering with providing smooth outer surfaces upon firing, or becomes undersirably roughened by passing through the kiln on rollers.
- providing unique shapes of such elements was limited because not all such configurations could stably pass through the kiln on rollers.
- the bottom surfaces of the prior art ceramic elements illustrated in Figs. 10 and 11 could not be successfully glazed because these surfaces rested against the rollers while passing through the kiln. Uneven surfacing was especially a problem with the prior art ceramic having the curved surfaces illustrated in Fig. 11, because these elements tend to rock while passing along the rollers in the kiln, resulting in uneven firing and subsequent glazing. l
- the present invention solves these disadvantages by versatilely firing the ceramics without damaging the outer surfaces thereof.
- the present invention is directed to a composite having pair of clay or ceramic elements mating and secured together in complementary fashion after being individually passed on rollers through a kiln.
- the outer surface(s) of the composite is glazed either before or after firing in the kiln, in any event before securing the individual elements together.
- the individual ceramic elements are advanced through the kiln on rollers. Previously, it was not possible to successfully glaze the surfaces of the ceramic before or after passing along the rollers, because this surface was unduly roughened.
- ceramics designed to have irregular outer surfaces could not be stably balanced and passed along the rollers through the kiln to ensure comprehensive uniform extrusion, glazing and firing along all surfaces.
- the present invention it is now possible to successfully extrude, glaze and fire the ceramic in a kiln without damaging the outer surface thereof, to provide a uniform ceramic.
- the inner surface of each element contacting the rollers in the kiln now bears the production marks and does not interfere with smoothing or glazing the outer surface of the composite formed thereby.

- Fig. 1 illustrates one embodiment in which the two complementarily-shaped ceramic elements 1a, 1b each have two plateaus 4 each in the shape of a substantially rectangular parallelepiped and having a cylindrical opening 5 therethrough, and a protruding edge 6 in the shape of a substantially rectangular parallelepiped along one side thereof.
- the outer opposite surfaces 9 of the ceramic elements 1a, 1 b are flat after being secured together, and with the joint 7 between the elements formed at perpendicular edges after the elements are secured together.
- the inner tube 2 is inserted into the cylindrical openings, with the end plate 3 being secured against a lateral edge of the elements 1a, 1b by the screws 8 as illustrated, in turn securing the complementary-shaped elements together (best seen in the top view illustrated in Fig. 9 with respect to the embodiment illustrated in Fig. 2 infra).
- each said element opposite the flat outer surface 9 thereof, i.e. , the inner surface having the respective plateaus 4 and valleys 10 therebetween, is rested against the rollers when passing through the kiln.
- One of the elements e.g., element 1b, is then inverted to be secured to element 1a.
- the drawings also indicate preferred dimensions in inches and millimeters (in brackets) of the composite element after being secured together.
- the composite element can have different sizes with different dimensions in similar proportions to one another.
- Fig. 2 illustrates one embodiment in which one 1a of the complementarily-shaped ceramic elements 1a, 1 b has four plateaus 4 each in the shape of a substantially rectangular parallelepiped and having a cylindrical opening 5 therethrough, and the other element 1 b has three plateaus 4 each in the shape of a substantially rectangular parallelepiped and having a cylindrical opening 5 therethrough, and two protruding edges each in the shape of a substantially rectangular parallelepiped along opposite sides thereof.
- the outer opposite surfaces 9 of the ceramic elements 1a, 1 b are also flat after being secured together, with the joint 7 between the elements formed at opposite lateral edges 11 of the composite after the elements are secured together.
- Fig. 2 illustrates glazing of the outer surfaces 9 of the composite before or after each element 1a, 1 b has passed through the kiln and before the elements are secured together to form the composite.
- Fig. 3 illustrates one embodiment in which one 1a of the elements 1a, 1 b has four plateaus 4 each in the shape of a substantially rectangular parallelepiped and having a cylindrical opening 5 therethrough, with two outer plateaus each having a chamfer 12 extending outwardly towards an edge 14 of the joint, and with edges 13 of said element 1a on outer sides of the two outer plateaus also inclined toward the edge of the joint (e.g., in zigzag fashion).
- the other element 1 b has three plateaus 4 each in the shape of a substantially rectangular parallelepiped and having a cylindrical opening 5 therethrough, and two protruding edges each in the shape of a substantially rectangular parallelepiped along opposite sides thereof and having an inner zig-zag surface 16 angled outwardly towards the edge 15 of the joint.
- the composite has flat outer surfaces 9 after the elements are secured together, and with the joint 7 formed at corners on the same side of the composite.
- the individual elements 1a, 1b are formed by extrusion in a die, prior to firing in a kiln.
- the zig-zag edges formed by chamfer 12 and edges 13, 14 of element 1a can be formed by machining or cutting with a tool after extrusion or even after firing, with zig-zag surfaces 16 and edges 15 of element 1b also formed by machining or cutting with a tool after extrusion or even after firing.
- the elements 1a, 1b shown in the embodiment illustrated in Fig. 2 can be machined to form the zig-zag corners in the embodiment illustrated in Fig. 3.
- Fig. 4 illustrates one embodiment in which one 1a of the elements 1a, 1b has four plateaus 4 each in the shape of a substantially rectangular parallelepiped and having a cylindrical opening 5 therethrough, and the other 1b element has three plateaus 4 each in the shape of a substantially rectangular parallelepiped and having a cylindrical opening 5 therethrough, and two protruding edges 17 each in the shape of a substantially rectangular parallelepiped along opposite sides thereof.
- the composite has convexly-shaped opposite surfaces 18 after the elements are secured together, with the joint 7 formed at opposite lateral edges of the elements 1a, 1b.
- These surfaces 18 are inherently unstable when passing along rollers in the kiln.
- the present embodiment which positions the opposite internal surface having the plateaus 4 of each composite element 1 a, 1 b against the rollers, ensures these curved surfaces 18 are smoothly, uniformly fired within the kiln and subsequently glazed.
- Fig. 5 illustrates one embodiment in which one 1a of the elements 1a, 1b has four plateaus 4 each in the shape of a substantially rectangular parallelepiped and having a cylindrical opening 5 therethrough.
- the two outer plateaus each have a longer inner lateral side 19 and shorter outer lateral side 20, designed to facilitate mating with the other element 1 b.
- the other element 1 b has three plateaus 4 each in the shape of a substantially rectangular parallelepiped and having a cylindrical opening 5 therethrough, and two protruding edges 21 each in the shape of a substantially rectangular parallelepiped along opposite sides thereof.
- the composite has substantially V-shaped opposite surfaces 22 after the elements are secured together, with the joint 7 formed at opposite lateral edges of the elements. As with the embodiment illustrated in Fig.
- these surfaces are also inherently unstable when passing along rollers in the kiln.
- the present embodiment which also positions the opposite internal surface having the plateaus 4 of each composite element 1a, 1b against the rollers, ensures these surfaces 22 are smoothly, uniformly fired within the kiln and subsequently glazed.
- Fig. 6 illustrates one embodiment in which one 1a of the elements 1a, 1b has four plateaus 4 each in the shape of a substantially rectangular parallelepiped and having a cylindrical opening 5 therethrough, and the other element 1b has three plateaus 4 each in the shape of a substantially rectangular parallelepiped and having a cylindrical opening 5 therethrough, and two protruding edges 21 each in the shape of a substantially rectangular parallelepiped along opposite sides thereof.
- the composite has rippled or corrugated opposite surfaces 23 after the elements are secured together, with the joint 7 formed at opposite lateral edges of the elements.
- the trenches 24 formed between the ripples or corrugations were normally ruined by contacting the rollers during firing. However, as with the illustrated embodiments supra, the present embodiments prevents these trenches 24 from being ruined by positioning the opposite, internal surfaces having the plateaus 4 of each ceramic component against the rollers when firing.
- Fig. 7 illustrates one embodiment in which one 1a of the elements 1a, 1b has four plateaus 4 each in the shape of a substantially rectangular parallelepiped and having a cylindrical opening 5 therethrough, and the other element 1b has three plateaus 4 each in the shape of a substantially rectangular parallelepiped and having a cylindrical opening 5 therethrough.
- the outer surfaces 25 of the respective elements 1a, 1b are asymmetrically slanted as illustrated, to form a bulge or protrusion 26 at one end thereof, these bulges or protrusions 26 situated diametrically opposite one another as illustrated when the elements 1a, 1b are fastened together.
- the plateau remote from the bulge or protrusion 26 has a longer lateral side than the plateau immediately adjacent the bulge or protrusion 26, with the element 1b having three plateaus 4 having two protruding edges 21 each in the shape of a substantially rectangular parallelepiped along opposite sides thereof.
- the composite has asymmetrically inclined opposite surfaces 25 after the elements are secured together, with the joint 7 formed at opposite lateral edges of the elements, i.e. , between the large and small curved lateral ends 27, 28 as illustrated.
- these surfaces are also inherently unstable when passing along rollers in the kiln.
- the present embodiment which also positions the opposite internal surface having the plateaus 4 of each composite element 1a, 1b against the rollers, ensures these surfaces 25 are smoothly, uniformly fired within the kiln and subsequently glazed.
- Fig. 8 illustrates one embodiment in which the elements 1 are essentially identical and each are in the shape of a semi-cylinder having a flat inner surface 29, an curved outer surface 30 and holes 5 for receiving tubes 2 and screws 7.
- the flat inner surfaces 29 are placed against the rollers in the kiln to be be stably passed therethrough for firing, ensuring uniform, undamaged glazing of the outer curved surfaces 30.
- the glaze is brushed on a smooth surface or combed onto a rough surface (e.g., Fig. 6).
- the ceramic elements are each fired in the kiln at temperatures of about 1100°C-1200°C for several hours a day.
- the tube 2 and plate 3 are each made of aluminum or stainless steel, while each element is ceramic or terra cota.
- Fig. 12 schematically illustrates an end view of an additional embodiment in which both parts 1a and 1b have better support when produced on a roller kiln. More particularly, the corners 26 are sharp, unlike the bulges or protrusions 26 shown in the embodiment of Fig. 7.
- Fig. 13 illustrates an embodiment similar to Fig. 12, in which the front edge (from the viewing direction on the right) of each element 1a, 1 b is cut as shown, before the two elements 1 a , 1 b are joined together.
- the cut joint forms a hairline joint 7 as shown which is (due to manufacturing tolerances) much less visible than the joint 7 shown in the other embodiments.
- Fig. 14 schematically illustrates an end view of a further modification in the embodiment illustrated in Fig. 13, in which to conceal the joint line from the front view (from the right in Fig. 14), the joint 7 formed between elements 1a and 1 b is not located in the front of the joined composite. Additionally, elements 1a and 1 b each include respective support legs or tabs 31 a, 31 b that will ultimately be cut off before joining the two elements together. The surface of one 1 a of the elements 1 a, 1 b can be rippled as shown.
- Fig. 15 schematically illustrates an end view of a further modification in the embodiment illustrated in Fig. 14, in which additional supports or tabs 32a, 32b of the individual elements 1a, 1 b are cut off or notched before assembling the two elements 1a, 1b together. This also allows for an additional metal support to be inserted into the joined composite as illustrated.
- Fig. 16 schematically illustrates an end view of an embodiment in which the two symmetric individual elements 1a, 1b form a new trapezoidal shape when joined together. Additionally, due to the specifically-designed shape of the elements 1a, 1b, an additional metal support can be inserted in the middle of the composite and retain the two elements 1a, 1b together by using clips 33 as shown.
- Fig. 17 schematically illustrates an end view of an embodiment in which the two symmetrical individual elements form a rectangular parallelepiped shape when joined together. Additionally, due to the specifically-designed shape of the elements 1a, 1b, an additional metal support can be inserted in the middle of the composite and hold the two elements 1a, 1b together, by using clips 33 which are inserted into the core slots/holes
- Fig. 18 schematically illustrates an end view of an embodiment in which the two symmetrical individual elements 1a, 1b form a rounded triangular shape when joined together, i.e. , have a rounded apex. Additionally, due to the specific design of the elements 1a, 1b, an additional metal support can be inserted in the middle and hold the two elements 1a, 1b together by using clips 33 which are inserted into the core slots/holes of the elements 1a, 1b (hidden from view).
