 Method and apparatus for molding ceramic ware

Details
Inventors: Benavidez, Carl R.;

Primary Examiner: Parrish; John A.

Attorney, Agent or Firm: Brown & Martin

A method and apparatus for molding ceramic ware includes a support table having a horizontal axis of rotation with a plurality of molds attached to opposed surfaces of the table for orientation in the vertical upright and vertical inverted positions. A fluid molding material is poured into the mold when in the open upright position and is permitted to set up to the extent of forming a shell and then inverted to pour the remaining molding material from the mold, while molds on the opposed surface are disposed in the upright position for receiving mold material.

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT Turning now to the drawings, there is illustrated in FIG.
1, an apparatus in accordance with the present invention.
The apparatus, designated generally by the numeral 10, includes a base or frame member which may be constructed of any suitable material, and includes a pair of substantially parallel side rails 12 and 14 connected at their ends to generally upwardly extending support members 16, 18, 20 and 22.
A pair of end rail members 24 and 26 secure the upwardly extending support members together at the base and may be secured to the ends of the base members 12 and 14.
The upwardly extending members are secuted together at the top by means of a pair of brace members 30 and 32.
A pair of journal brackets 34 and 36 are secured to the upper ends of the upwardly extending support members and each include a journal slot 38 and 40 respectively.
A support member or table of a generally rectangular configuration as in the illustrated configuration includes a plurality of cross frame members including a pair of end frame members 42 and 44 with intermediate cross members 46.
These cross members are disposed between and secured, such as by nails, bolts, screws or the like, to a plurality of planks or boards 48 defining an upper surface and planks or boards 50 defining a lower support surface.
These upper and lower or opposed support surfaces being spaced apart provide for ease of attachment of molds to the support structure.
The apparatus can, of course, be constructed of any suitable material.
A pair of journal pins 52 and 54 are secured to the end members and are detachably or removably positioned within the journal slots 38 and 40.
With this construction, the support table or a plurality of support tables may be utilized with a single base support structure.
A support table is simply lifted off the base support structure and another one put in its place.
This feature and the importance thereof will be discussed more fully later.
The table is thus capable of rotation about a horizontal axis thus presenting either one of the table support surfaces 48 or 50 upward or downward and thereby supporting a mold or plurality of molds in the vertically oriented upper upright or inverted positions as will be described
