Abstract
Abstract This invention relates to a safety device for the removal of caps from radiators and the like, and provided mechanism for the remote manipulation of a cap for its removal and which incorporates a deflection shield that turns any dangerous flow of fluid in harmless directions, whereby a person can safely open a radiator even when under abnormal pressures that would present dangerous conditions.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
170 words
A fluid-deflecting cap remover having an operating axis to be disposed coincidental with the axis of the caps of radiators and the like, and comprising, a manually positionable handle-shaped body, a fluid deflector of curvilinear semicylindrical configuration fixedly carried by and at the lower end of the body and having a top section tangentially normal to and overlying the operational axis of the body and extending laterally to one side of the body and having one side section depending below the body from the lateral extremity of the top section to shield lateral projection of fluids dispersed along and laterally from the axis of the cap, an operator extended through the body and rotatably movable in a bearing therein and with a manually engageable handle fixed thereon above the deflector, and a cap coupler fixed to the operator beneath the deflector and manipulatable with the operator to remove the cap by movement of the same rotatably about and along said operating axis and into aligned turning engagement with the cap.
Claim 2
Dependent Claim
170 words
A fluid-deflecting cap remover having an operating axis to be disposed coincidental with the axis of the caps of radiators and the like, and comprising, a manually positionable handle-shaped body, a fluid deflector of curvilinear semicylindrical configuration fixedly carried by and at the lower end of the body and having a top section tangentially normal to and overlying the operational axis of the body and extending laterally to one side of the body and having one side section depending below the body from the lateral extremity of the top section to shield lateral projection of fluids dispersed along and laterally from the axis of the cap, an operator extended through the body and rotatably movable in a bearing therein and with a manually engageable handle fixed thereon above the deflector, and a cap coupler fixed to the operator beneath the deflector and manipulatable with the operator to remove the cap by movement of the same rotatably about and along said operating axis and into aligned turning engagement with the cap.
Claim 3
Dependent Claim
28 words
The fluid-deflecting cap remover as set forth in claim 1 and wherein the deflector is comprised of flexible material adapted to accommodate the device to otherwise obstructed positions.
Claim 4
Dependent Claim
31 words
The fluid-deflecting cap remover as set forth in claim 1 and wherein the body comprises a tubular sleeve surroundingly spaced from and thereby insulated from the bearing which carries the operator.
Claim 5
Dependent Claim
45 words
The fluid-deflecting cap remover as set forth in claim 1 and wherein the operator comprises a shaft with axially spaced stops for free limited reciprocation within said bearing, whereby the deflector carried by the body and the coupler carried by the operator are independently manipulatable.
