Abstract

This article describes a two-piece mounting device for mounting a control device, such as a cathode-ray tube, to a machine and for allowing complete freedom of movement, within design parameters, for positioning the control device for ease of viewing. The device provides both rotational and rocking movement to adjust position in two dimensions and allows quick assembly/disassembly from the machine. The figure shows a base piece 10 which is to be fastened to the top of a machine and a swivel piece 11 which is to be fastened to the bottom of a control device. Base piece 10 contains a concave spherical surface 12 which mates with a convex spherical surface 13 on the underside of swivel piece 11.

Locking Head for Sliding and Rotational Control Device

This article describes a two-piece mounting device for mounting a control device, such as a cathode-ray tube, to a machine and for allowing complete freedom of movement, within design parameters, for positioning the control device for ease of viewing. The device provides both rotational and rocking movement to adjust position in two dimensions and allows quick assembly/disassembly from the machine. The figure shows a base piece 10 which is to be fastened to the top of a machine and a swivel piece 11 which is to be fastened to the bottom of a control device. Base piece 10 contains a concave spherical surface 12 which mates with a convex spherical surface 13 on the underside of swivel piece 11. To join the pieces 10 and 11 together, piece 11 is lowered onto piece 10 with opening 15 accommodating bushing 14 which is raised above spherical surface 12. Slot 16 fits through tab 17, and a corresponding slot (not shown) in piece 11 fits through tab 18 thus allowing the two spherical surfaces 12 and 13 to mate with one another. When properly positioned, piece 11 can rotate in either direction but is limited to a total of 270OE by stop surfaces 19 and 20 which meet side surfaces 21 and 22 at the extent of rotation allowed. Piece 11 also slides or rocks on surface 12 to tilt the control device a desired amount. Ribs 23 and 24 together with bushing 14 limit the amount of tilt. Note that bushing 14 contains a lip 25 exten...
