Abstract
Abstract There is provided herein a receptacle base with self-aligning conical stud which is mutually retained by a pin containing an internal, concentrically mounted hydraulic actuator to permit maximum locking and unlocking force in minimal space. Double eccentric bushings in conjunction with double axial nuts provide three mutually perpendicular adjustments for the stud and receptacle. Conical male and female lock members provide repeatability of location one member to the other which in conjunction with the three mutually perpendicular adjustments minimize the required accuracy of location of the several elements which comprise the mechanism.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
224 words
A locking mechanism and actuating means therefor comprising: a pin mounted adjacent one of its ends on a first structure and having a frustoconical head pierced by a transverse aperture adjacent its other end; a receptacle mounted on a second structure and defined by an internal frustoconical surface complemental to said pinhead with a similar transverse aperture therethrough adapted to align with the aperture in said pin end when the pin end is located therein; a container mounted on and projecting from one side of said receptacle and having an opening therein in alignment with the receptacle aperture aforesaid; a bolt mounted for reciprocation in said container to and from positions totally within the container and extending therefrom through said opening therein and totally through said receptacle transverse aperture; seals associated with the adjacent portions of said bolt and said container; a port in said container communicating with opposite surfaces at the end of said bolt; and a fitting mounted in each said port for the operative connection thereto of a source of fluid under pressure whereby fluid entering one of said ports forces said bolt to its extended position aforesaid through said receptacle aperture and pin aperture when the pin end is located therein while fluid entering the other of said ports forces said bolt to its contracted position totally within said container.
Claim 2
Dependent Claim
224 words

Claim 3
Dependent Claim
43 words
The invention of claim 1 including a plurality of eccentric bushings surrounding said pin and mounted for rotation on said first structure to thereby establish central openings having a predetermined disposition of its axis for location of the longitudinal centerline of the pin.
Claim 4
Dependent Claim
36 words
The invention of claim 1 including a pair of nuts threadably mounted on said pin on opposite sides of said first structure to establish and maintain the location of said pinhead relative to said first structure.
Claim 5
Dependent Claim
36 words
The invention of claim 1 wherein multiple of said locking and actuating mechanisms are associated one with another and connected to common fluid pressure lines whereby the actuation of all of the mechanisms occurs in unison.
Claim 6
Dependent Claim
55 words
The invention of claim 2 wherein two eccentric bushings are employed one disposed within and substantially coextensive with the other with the internal diameter of the inner bushing approximately equal to the outside diameter of said pin and the external diameter of the inner bushing approximately equal to the internal diameter of the outer bushing.
Claim 7
Dependent Claim
32 words
The invention of claim 1 wherein said first structure is pivotally mounted on said second structure for swinging movement relative thereto whereby said pinhead is located in and removed from said receptacle.
Claim 8
Dependent Claim
35 words
The invention of claim 1 wherein: said container is a cylinder with its opening at one end thereof; said bolt carries a piston head; and said ports communicate with opposite sides of said piston head.
Claim 9
Dependent Claim
87 words
The invention of claim 7 wherein: said cylinder includEs an internal, stationary piston head proximate its said open end; said bolt is tubular having a length substantially equal to that of said cylinder, an internal diameter substantially equal to the overall diameter of said stationary piston head and an effective external diameter substantially equal to the internal diameter of said cylinder; and said bolt piston head is disposed at all times between said stationary piston head and the end of said cylinder remote from its open end.
Claim 10
Dependent Claim
36 words
The invention of claim 8 wherein one end of said tubular bolt is generally conical and disposed at all times on the opposite side of said stationary piston head with respect to said bolt piston head.
