Abstract

582,962. Core' &c. making machines. SMITH, A. B., and SMITH, C. R. Sept. 6, 1944, No. 17076. [Class 83 (i)] A machine for moulding cores &c. from sand &c. by pressing or vibrating, inverting and drawing, has a head 3x to carry a core-box table 6 and a pressure plate 18 with its actuating means, mounted on a horizontal rotary shaft 3 and locking means comprising a spring-loaded dog 35 adapted to engage an eliptical cam 36 secured to the head 3x and provided with notches 37 at opposite ends of its major axis, whereby the dog applies a braking pressure before it.locks the head in either the normal or inverted position. The dog 35 may be carried by a lever 39, Fig. 2, and be pressed up by a loose pin 44 which engages recesses in the lever 39 and in a sliding rod 43, pressed up by an adjustable spring 42. The table 6 is supported, when in moulding position, by engaging fixed abutments 8. The plate 18 is carried by a rod 17 sliding in a head 15 arranged to swivel on a tubular arm 4 of the head 3x. A hand lever 23 pivoted to the head 15 through a link 21 and directly to the rod 17 is pulled towards the shaft 3 by a spring 26 arranged in the arm 4. The lever 23 is guided in a slot 32 of a member 31 fixed to the end of the arm 4 during ramming and drawing, but after drawing it can be moved out of the slot along a surface 33 while the head 15 swivels-about the arm 4 to move the plate 18 to one side. The dog 35 may be forced out of a notch 37 by rotating the head 3x by hand or it may be pulled down by a treadle connected to the lever 39.
