Machinery safety guards

Abstract: An easily removable safety guard for application to the barrel of a vertical drilling machine so as to overlie the drill bit comprises a coaxially arranged telescopingly connected, guard body and guard sleeve. The guard body is yieldably and resiliently retained in a mounting ring which is in turn clamped on the barrel of the drilling machine. The guard sleeve, or skirt, depends from the guard body to engage at its underside the workpiece or machine bed plate. The guard body moves progressively downwardly relative to the sleeve during progressive downward motion of the barrel. The sleeve is provided with clear-view panels therein and the guard body includes breaker bars to break off slivers of metal cut from the workpiece. Spring pressed ball catches enable the guard body with its sleeve, to be readily removed from the mounting ring with a downward extraction force.

Guard for isolating recessed ceiling lights from combustible insulation

Abstract: Thin gage pre-creased and pre-punched sheet aluminum is cut to length from a supply roll on the job site where light fixtures are recessed in a ceiling containing combustible insulating material. The thin sheet metal is readily formed into a guard or dam of the necessary size and shape and placed around the recessed light fixture to prevent the insulation material from coming into contact therewith. Bendable tabs along one edge of the sheet material form bottom anchoring elements on the guard which can be stapled to the ceiling structure. The guard or dam is held in its erected form by screws or other fasteners engaging in the pre-punched openings of the sheet material. The guard is open from top to bottom and a generous air space is provided between the side wall of the guard and the light fixture.

Machine tool guard door assembly

Abstract: An automatic programmed machine tool having guard doors is shut down by an interlock system whenever a guard door is opened.

Power press break guard

Abstract: A reciprocating preferably transparent break guard is disclosed for use in connection with a reciprocating machine, such as a bending machine. Adjustable switching means are operatively associated with the machine for controlling the actuation of a hydraulic piston connected to a frame for the guard. When the machine is in its upper position for receiving a workpiece, the switching means causes the piston to be actuated to maintain the guard in its upper position free from interference with the break. When the machine is actuated and starts its downward stroke, the switching means actuates a solenoid to release the piston causing the guard to drop smartly in front of the break thereby preventing the operator from accidentally inserting hands or fingers into the break of the machine. In its lowered position, the machine again actuates the switching means to operate the piston to raise the guard to its upper position. The position of the lower edge of the break guard is adjustable relative to a workpiece receiving surface on the machine to admit a workpiece into the break while excluding the hand or finger of the operator from the break.
