ABSTRACT:
In a press (10) for briquetting loose ceramic powders into cohesive compacted articles, a shuttle (24) and shoe (26) is employed for receiving an inflow of loose powders and adapted for filling the die cavity with powder. Simultaneously the shoe (26) displaces an ejected briquetted article. The characteristics of the longitudinal movement of the shuttle (24), including its range, speed, and phase of movement, are controlled by a power shaft having a crank shaft (50) coupled to the power shaft through an adjustable plate (39). The adjustable plate (39) is angularly adjusted, and the pivot connection (48) between the crank shaft (50) and the center (54) of the adapter plate (39) is radially adjusted. The described adjustments regulate the range, speed, and phase of movement of the shuttle (24). Between the crank shaft (50) and the shuttle (24) is a rocker shaft (60), rocker arms (66, 68) and struts (76).
The shuttle (24) may be biased against the press (10) by means of a power cylinder (86) and rod (87) which biases the shuttle (24) toward the platen surface (25) of the press (10).
