Abstract

965,522. Machinery guards. JAMES HOLT (ENGINEERS) Ltd. May 23, 1963, No. 20531/63. Heading F2J. In an hydraulically or pneumatically operated toggle press, lowering of a guard G into a position protecting the work-table a causes a valve C to be opened to admit hydraulic fluid or compressed air to a cylinder D to operate the press, and moves a lever b<SP>2</SP> away from a position in which it prevents inadvertent motion of the toggle links d, d<SP>1</SP>. The toggle link d, which is adjustable in length, is pivoted to a tool-carrying head A movable on vertical slides B. The guard G, having an operating handle g, moves on parallel levers g<SP>1</SP>, g<SP>2</SP> which are rigid with rods b, b<SP>3</SP> pivotally supported in the press frame B<SP>1</SP>. Rod b carries a lever b<SP>1</SP> which depresses an operating plunger C<SP>2</SP> of the valve C when the guard is lowered. Rod b<SP>3</SP> carries a lever b<SP>4</SP> which, when the guard is lowered, contacts the end of the lever b<SP>2</SP> to pivot it, so that the other end of lever b<SP>2</SP> is moved clear of the pivot joint d<SP>2</SP> of the toggle links. The lever g<SP>2</SP> carries a counter-balance weight g<SP>3</SP>. The stroke of the ram in cylinder D can be adjusted by means of an adjustable end wall, in the righthand end (Fig. 2) of the cylinder, controlled by a screw mechanism (not shown).
