Abstract
Abstract An apparatus for homogeneously joining together the cut surfaces of a seag ring of elastic material, which has been cut open radially on one side, particularly for stern tube seals in ships, utilizing a body member and segment provided with apertures corresponding to the contours of the sealing ring and utilizing clamping means for fastening the ends of the sealing ring, the cut surfaces of which have been provided with an adhesive, the body member receiving the ends of the divided sealing ring being made in the form of a shaped body divided in the radial direction of the sealing ring, with its parts being relatively movable towards and away from one another in a substantially tangential direction.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
174 words
An apparatus for homogeneously uniting the ends of a sealing ring split radially on one side and provided with adhesive comprising two body members, each member defining a guide slot therein and a profile of a portion of the sealing ring to be united, two segments coacting with said members each of which defines a guide slot therein and the remaining portions of the profile of the sealing ring to be united, each body member and segment when assembled defining an aperture shaped to the contour of the sealing ring, means on each of said body members for effecting relative movement between said body members towards and away from each other in a direction tangential to said ring in said apertures to clamp said ring with its adhesive coated ends pressed together to effect a homogeneous joint between them, and two slide bars each of which is slidable within a said guide slot in a body member and cooperating segment when said member and segment are aligned for securing said segments to said members.
Claim 2
Independent Claim
174 words
An apparatus for homogeneously uniting the ends of a sealing ring split radially on one side and provided with adhesive comprising two body members, each member defining a guide slot therein and a profile of a portion of the sealing ring to be united, two segments coacting with said members each of which defines a guide slot therein and the remaining portions of the profile of the sealing ring to be united, each body member and segment when assembled defining an aperture shaped to the contour of the sealing ring, means on each of said body members for effecting relative movement between said body members towards and away from each other in a direction tangential to said ring in said apertures to clamp said ring with its adhesive coated ends pressed together to effect a homogeneous joint between them, and two slide bars each of which is slidable within a said guide slot in a body member and cooperating segment when said member and segment are aligned for securing said segments to said members.
Claim 3
Dependent Claim
40 words
The apparatus according to claim 1, wherein said means comprise at least one protrusion on one body member and a recess in the other body member to receive said protrusion to ensure relative linear movement between said shaped body members.
Claim 4
Dependent Claim
22 words
The apparatus according to claim 2, wherein said means include a control element for controlling said relative movement of the body members.
Claim 5
Dependent Claim
34 words
The apparatus according to claim 3, wherein said recess is a threaded bush and said control element is a threaded spindle cooperating with said threaded bush to effect relative movement between said body members.
Claim 6
Dependent Claim
17 words
The apparatus according to claim 1, including means to slidably secure said slide bar to said member.
Claim 7
Dependent Claim
22 words
The apparatus according to claim 5, wherein each slide bar carries at one end a control knob for moving said slide bar.
Claim 8
Dependent Claim
29 words
The apparatus according to claim 1, wherein the guide slot of each segment is beveled so that each slide bar can apply a clamping action against said body member.
Claim 9
Dependent Claim
20 words
The apparatus according to claim 1, wherein both segments are identical and each is joined to a different body member.
Claim 10
Dependent Claim
40 words
The apparatus according to claim 8 including two body parts each of which is attached to a body member by a threaded screw which extends through each said body part and engages in a threaded recess in each body member.
Claim 11
Dependent Claim
26 words
The apparatus according to claim 9 including a support provided on the rear of each body part which extends in the direction of said body member.
Claim 12
Dependent Claim
28 words
The apparatus according to claim 1 including a heater integral with each of said body members and a handle provided on each body member adjacent to said heater.
