Abstract
6012. Heath, A. W., Freeman, R. J., and Phillips, S. March 10. Guards, controlling.-The guard for a power or other press is arranged so that the two hands of the operator are required for starting the press, and means are also provided for closing the guard should the ram accidentally fall. The starting-lever j is returned to the out of gear ' position by a spring and is retained in that position by means of a weighted detent k, which is released by a projection a<1> on the guard a when the guard is moved to the closed position against the action of a spring. Thus, in starting the press, one hand of the operator is required to retain the guard, while the other hand is employed in moving the lever j. A quadrant f adjustably connected to the press ram e. carries a roller engaging a lever c pivoted at one end to a bar b carried by the press and engaging through a roller c<3>, an inclined plate d on the guard. Should the ram fall, the lever e is depressed and forces the guard to the closed position, removing the operator's arm out of danger. The sudden movement of the guard causes abnormal depression )f a buffer n and enables a detent o to engage a pin p on the guard to retain it in the closed position. Specification 9423/13 is referred to.
