Abstract
563,299. Machinery guards. THOMPSON, J., and DARLING, M. H. Jan. 29, 1943, No. 1509. [Class 80 (iv)] A guard for presses has a safety member 1 which moves upwards to obturate the tool's zone and an operator-displacing member 22 which moves outwards from the said zone during the working stroke of the press. As shown, the member 1 is moved by a cable 15 which is fixed at 14 and passes round a pulley 12 movable with the press ram and over a pulley 10 fixed to the machine frame. The member 22 is a bar to which are pivoted links 23, 24. Link 23 is pivoted at 25 to the bottom of the member 1 and link 24 is pivoted at 27 to the machine frame, the two -links 23, 24, being nearly in a straight line when the guard is in its lowered position. Thus during the early part of the movement of the guard to its operative position the bar moves rapidly outwards to displace the machine operator if he is too close. The length of the bar 24 and the position of the pulley 12 are adjustable.
