GERMANY.
POTTERY-MOLDING MACHINE.
Application filed July 31, 1914..
To all whom it may concern:
Be it known that I, CHRISTIAN ECKSTEIN, subject of Germany, residing at Weiden, Bavaria, Germany, have invented certain new and useful Improvements in Pottery- Molding Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to an improved machine for manufacturing vessels from plastic substances, such as clay and the like.
The object of my invention is to provide an apparatus wherein I dispense entirely with the use of a mold and core, the shaping being performed solely with the aid of rolls, which act upon the plastic mass internally and externally. To this end I use, in combination with the usual revolving disk or potters wheel, two or more vertical or inclined rolls for acting on the outside of the work, and a roll or rolls for acting on the inside, the rolls being disconnected from the disk, so that the latter revolves the work between the internal and external rolls, which may, during the operation, be moved longitudinally. In the course of the operation the rolls are adjusted in relation to each other, preferably with the aid of a templet or pattern plate, for the purpose of fashioning the work. The rolls and the pattern plate or templet are exchangeable, and the longitudinal section of the rolls corresponds with the final shape of the object formed. I may provide a horizontal or approximately horizontal roll or rolls above the revolving v disk, to act on the work at the top.
An embodiment of the invention is shown in the accompanying drawings, in which Figure 1 is a plan view, and Fig. 2 a side view, partly in section. Figs. 3 and 4 show details.
- In the drawings a designates the revolving disk, upon which a lump of the suitably prepared plastic mass is placed. A frame 6,

Serial No. 854,231.
pairs of rolls can be drawn apart, to lie at the sides of the lump of plastic material, whereas another roll, designated 7, carried by the frame. Z), is plunged into the lump. The frame also carries a horizontal roll 9. By moving the two pairs of rolls e 6 and 6 6 toward the roll f the work is centered and squeezed so as to become lengthened in the upward direction. The roll f may be vertically movable in the frame, or may be adjustably fixed to the same, and by lowering it on to the work the mass is squeezed from above. The lateral and vertical squeezing operations are preferably performed alternately several times, whereby the mass is suitably prepared for uniform molding.
A templet or pattern plate h is hinged to the table to on which the disk 64 revolves, the templet being fixed by a lug 2 to a spindle 2', which can be fixed by means of a pin 70 to hold the templet in a vertical position, as shown in Figs. 2 and 4:. The arms 0 and (Z are laid against the lateral edges of the templet, and connected to each other by a coiled spring 8, which holds them against the said edges, so that the templet determines the diameter of the article molded by the rolls.
A crank Z, bevel gears n, and worm u enable the roll f to be adjusted in a horizontal direction in relation to the rolls e e e e, for determining the thickness of the wall of article molded. D
By turning the crank m the frame 6, with the rolls, can be raised during the molding operation, so that the mass is driven up between the rolls e e c and the roll 7", and the desired shape is obtained. Some objects may be molded without moving the frame upward. The weight of the frame is balanced by weight (not shown) attached to a cord 1. All the rolls are adjustable and exchangeable, and any desired number of rolls may be used.
What I claim as my invention and desire to secure by Letters Patent of the United States is In a pottery molding machine, the combination of a horizontal revoluble disk adapted to support plastic material, a frame vertically movable in relation to said disk, oppositely disposed rolls for acting against the outer surface of said plastic material, means whereby said rolls are slidably suspended from said frame and are movable toward and from each other, a roll suspended from said frame and adapted to act against the In testimony whereof I hereunto aflix my ifnner surface 05 said plastic material, lglleans signature in the presence of two Witnesses.
or movin sai last named r011 toWar and from eithe i' of said first mentioned rolls, and CHRISTIAN ECKSTEIN' an additional, suspended, horizontal roll Vitnesses:
adapted to act against the upper edge of CARL BAUSCHER,
said plastic material. I J OH. LEONI-IARDT.
