Abstract

273,006. Jones, W. H. March 26, 1926. Guards, controlling.-A pivoted guard 6 for a power press &c. is operated from the slide 3 or other reciprocating part by a link 10 connected to a cranked arm 11 and, by a slot 13, to a pin 12 on the connecting-rod 5, so that the guard is displaced, as shown, on the upstroke, and returns by gravity or a spring 9 to the vertical guarding-position on the downstroke. The lost-motion connection 12, 13 allows the stroke of the slide 3 to exceed that of the link 10, and thus to be varied according to the class of work. Downward movement of the guard is limited by a stop 14. A pin may be inserted in a hole 15 to hold the guard out of action.
