Abstract
A guard for a power-feed drill having a fluid inducer protects an operator from coming in contact with a rotating drive assembly. The drive assembly is enclosed by a cylindrical housing having a slotted opening through which a fluid inducer connection extends. The guard comprises a rotatable tube concentrically disposed within the housing and sleeved over the drive assembly so as to cover the opening presented by the slot. The fluid inducer connection passes through a helical groove in the tube.
Claims23
A safety guard for a drill having a rotating spindle assembly and a fluid inducer connector displaced during drill feed through a slot in a housing covering the spindle assembly, comprising:
- a cylindrical tube rotatably disposed within the housing and sleeved over the spindle assembly to guard an operator from contact with the spindle assembly through the slot, the tube including a helical groove through which the fluid inducer connector extends, the cylindrical tube adapted to rotate as the fluid inducer connector is linearly displaced along the slot in the housing;
- wherein the length of the tube is greater than the length of the slot.
A guard for a machine tool having a linearly displaceable tool drive covered by a protective shield and provided with a fluid supply connector, the fluid supply connector being displaceable within and extending through a slot in the shield, comprising:
- a tube concentrically disposed between the shield and the tool drive, the tube having a sidewall covering the slot in the shield to prevent operator contact with the tool drive, the tube including a curved groove therein through which the fluid connector extends;
- wherein the length of the tube is greater than the length of the slot.
A guard for use with a portable drill having a powerfeed rotating drive for linearly displacing a rotary drill tool, a protective shield surrounding the drive and having a slot therein, and a fluid connector passing through the slot for coupling the drill tool with a supply of fluid, the guard for protecting a drill operator from contact with the rotating drive through the slot, the guard comprising:
- a guard body covering the slot and disposed between the shield and rotating drive, the guard body having a curved groove therein through which the connector transversely extends, the connector being displaceable through a length of the groove as the rotary drive linearly displaces the tool;
- wherein the length of the guard body is greater than the length of the slot.
A safety guard for a drill having a rotating spindle assembly and a fluid inducer connector displaced during drill feed through a slot in a housing covering the spindle assembly, comprising:
- a cylindrical tube rotatably disposed within the housing and sleeved over the spindle assembly to guard an operator from contact with the spindle assembly through the slot, the tube including a helical groove through which the fluid inducer connector extends;
- wherein the tube is captured between opposing shoulders within the housing.
