Abstract
Abstract This invention relates to a method of and a device for enabling the insertion of a sealing element into a face-cut groove with a minimum of time and effort, together with the accuracy and quality required. This particularly has to do with practical field maintenance of seals while eliminating all problems usually encountered during installation of prior insertable seals. This is accomplished by means of a fixture which holes the seal element by means of an applied vacuum, and the utilization of the fixture to insert the seal element into a groove quickly and accurately.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
59 words
A method of applying a seal element in a facecut groove comprising the steps of conforming the seal element to the outline of the groove, utilizing a vacuum and retaining the outline of the seal, while retaining the outline of the seal element aligning the seal element with the groove, and thereafter inserting the seal element into the groove.
Claim 2
Independent Claim
59 words
A method of applying a seal element in a facecut groove comprising the steps of conforming the seal element to the outline of the groove, utilizing a vacuum and retaining the outline of the seal, while retaining the outline of the seal element aligning the seal element with the groove, and thereafter inserting the seal element into the groove.
Claim 3
Dependent Claim
19 words
The method of claim 1 with said seal element insertion being at least in part accomplished by fluid pressure.
Claim 4
Dependent Claim
42 words
The method of claim 1 with the seal element being transversely deformed by the action of the vacuum thereon to temporarily reduce the width of that surface thereof to be placed in a groove thereby facilitating the insertion of the seal element.
Claim 5
Independent Claim
128 words
A method of applying a T-cross sectional seal element in a facecut groove of a component wherein said groove is of a configuration other than a straight line configuration, said method comprising the steps of providing a seal element inserting member and forming thereon a projection of the same configuration as the groove with the projection also having a groove therein, conforming the seal element to the outline of said projection and seating the seal element on the projection with a portion of the seal element being received in the groove of the projection, aligning the projection with the facecut groove while retaining the seal element on the projection in alignment therewith, and then utilizing the projection inserting the seal element into the facecut groove in seating relation.
Claim 6
Independent Claim
128 words
A method of applying a T-cross sectional seal element in a facecut groove of a component wherein said groove is of a configuration other than a straight line configuration, said method comprising the steps of providing a seal element inserting member and forming thereon a projection of the same configuration as the groove with the projection also having a groove therein, conforming the seal element to the outline of said projection and seating the seal element on the projection with a portion of the seal element being received in the groove of the projection, aligning the projection with the facecut groove while retaining the seal element on the projection in alignment therewith, and then utilizing the projection inserting the seal element into the facecut groove in seating relation.
Claim 7
Dependent Claim
31 words
The method of claim 4 wherein the projection is narrower than the facecut groove and with the projection being inserted in the facecut groove in the positioning of the seal element.
Claim 8
Dependent Claim
31 words
The method of claim 4 togetheR with the step of drawing a vacuum within the projection groove and thereby effecting said maintaining of the seal element in alignment with the projection.
Claim 9
Dependent Claim
61 words
The method of claim 6 wherein the projection groove is deeper than that portion of the seal element received therein, and with the applied vacuum being sufficiently great to draw the seal element into the projection groove and temporarily transversely deforming the seal element and reducing the seal element thereby facilitating the insertion of the seal element in the facecut groove.
