Easy-on, easy-off sighting aid mount for a revolver

An apparatus having utility in mounting an auxiliary sighting aid on a firearm, the firearm being of the revolver type and having an axle upon which the revolver's cylinder rotates during firing, and said axle having an extension that is selectively movable by swinging between first and second positions adjacent the revolver's barrel, said first position being associated with a closed cylinder and being very close to the revolver's barrel, and said second position being rotated away from the barrel and being associated with an open cylinder, comprising:

• a. a rigid housing having a longitudinal bore that is sized and oriented to effect a slip fit with the extension of the cylinder's axle when the cylinder is open and the extension is in its second position, and the housing having a size and shape that precludes any interference with the barrel and frame as the cylinder is swung from its open to its closed position, and the housing having a length that causes the housing to be captured by rigid parts of the revolver when the cylinder is closed and the extension has been moved to its first position;
• and
• b. means associated with the rigid housing for holding an auxiliary sighting aid so that it is at least generally parallel to the revolver's barrel when the rigid housing has been slipped over the extension. sliding a part of the rigid mount in a telescopic manner over the revolver's ejector rod while the ejector rod has been temporarily swung outward to a position for loading the cylinder;
• b. maintaining the rigid mount on the ejector rod while the ejector rod is being swung back to a position in which the revolver may be fired;
• and
• c. attaching an auxiliary sighting aid to said rigid mount.

The method of mounting an auxiliary sighting aid on a firearm of the revolver type, and said revolver having a cantilevered ejector rod and a swing-out cylinder, comprising the steps of:

• a. securing a rigid mount for an auxiliary sighting aid on the revolver with a slip fit and without the necessity of making any permanent connections to the revolver, said slip fit being accomplished by the step of sliding a part of the rigid mount in a telescopic manner over the revolver's ejector rod while the ejector rod has been temporarily swung outward to a position for loading the cylinder;
• b. maintaining the rigid mount on the ejector rod while the ejector rod is being swung back to a position in which the revolver may be fired;
• and
• c. attaching an auxiliary sighting aid to said rigid mount.

(Rewritten in independent form). The method of mounting an auxiliary sighting aid on a firearm of the revolver type, and said revolver having a cantilevered ejector rod, comprising the steps of:

• a. securing a rigid mount for an auxiliary sighting aid on the revolver with a slip fit and without the necessity of making any permanent connections to the revolver, said slip fit being accomplished by the step of sliding a part of the rigid mount in a telescopic manner over the revolver's ejector rod;
• b. providing a friction member that is positioned between the rigid mount and the ejector rod, such that removal and installation of the rigid mount requires at least some manual force to be exerted against the resistance of the friction member;
• and
• c. attaching an auxiliary sighting aid to said rigid mount.

The method of mounting an auxiliary sighting aid on a revolver, said revolver having an ejector rod that is movable between open and stowed positions with respect to the revolver's frame, comprising the steps of:

• a. moving the ejector rod to its open position so as to create a significant clearance space around the ejector rod;
• b. connecting a rigid housing to the ejector rod while it is in its open position;
• c. restoring the ejector rod to its stowed position alongside the revolver's frame after the rigid housing has been connected thereto;
• and
• d. mounting an auxiliary sighting aid on the rigid housing, whereby the auxiliary sighting aid can be mounted in a desired relationship with respect to the revolver's barrel by virtue of connecting it to the ejector rod.
