Abstract
A manual rescue tool is disclosed. In one embodiment, the rescue tool has a hydraulic pump assembly having a hydraulic manifold block and an extension tube assembly extendable by the hydraulic pump assembly. The extension tube assembly may be mounted to and supported by the manifold block. The rescue tool may further include a first end tool operably connected to a first end of the extension tube assembly and an end plate assembly rotatably mounted to the manifold block.
Claims18
A manual rescue tool comprising:
- (a) a hydraulic pump assembly comprising:
- i. a manual hydraulic pump;
- ii. a hydraulic manifold block in fluid communication with the hydraulic pump;
- iii. a cylinder tube mounted to the hydraulic manifold block, the cylinder tube defining an interior volume that is in fluid communication with an outlet side of the manual hydraulic pump;
- iv. an oil reservoir tube mounted to the hydraulic manifold block, the oil reservoir tube and the cylinder tube defining an oil reservoir in fluid communication with an inlet side of the manual hydraulic pump;
- v. a cylinder rod having a first end and a second end, the first end having a piston slidable within the cylinder tube;
- and
- (b) an extension tube assembly comprising:
- i. an outer support tube mounted to the pump assembly hydraulic manifold block;
- ii. an inner support tube slidably received within the outer support tube, the inner support tube being operably connected to the second end of the cylinder rod;
- (c) a first end tool operably connected to the inner support tube of the extension tube assembly.

A hydraulic pump assembly comprising:
- (a) a manual hydraulic pump;
- (b) a hydraulic manifold block in fluid communication with the manual hydraulic pump;
- (c) a cylinder tube mounted to the hydraulic manifold block, the cylinder tube defining an interior volume that is in fluid communication with an outlet side of the manual hydraulic pump;
- (d) an oil reservoir tube mounted to the hydraulic manifold block, the oil reservoir tube and the cylinder tube defining an oil reservoir in fluid communication with an inlet side of the manual hydraulic pump;
- and
- (e) a cylinder rod having a first end and a second end, the first end having a piston slidable within the cylinder tube;
- (f) wherein the cylinder tube has a bypass feature configured to allow hydraulic fluid to flow from the interior volume of the cylinder tube into the oil reservoir when the piston is moved within the cylinder tube beyond the bypass feature.
