A connector (10, 110) for joining a plurality of elements (15, 20; 115, 120) having attachment apertures (19, 21; 119, 121) therein including, a pin (25; 125, 125') having a radially extending head (27; 127) and a shank (26; 126, 126') extending axially from the head and having a tapering outer surf
A connector (10, 110) for joining a plurality of elements (15, 20; 115, 120) having attachment apertures (19, 21; 119, 121) therein including, a pin (25; 125, 125') having a radially extending head (27; 127) and a shank (26; 126, 126') extending axially from the head and having a tapering outer surface (29; 129, 129') over at least a portion of the axial extent thereof, a sleeve (35, 135) insertable in the attachment apertures and having a tapering inner surface (38; 138, 138') over at least a portion of the axial extent thereof for engaging the tapering outer surface of the pin, a discontinuity (37, 137) in the sleeve extending at least a portion of the axial extent thereof, and fastener (45, 50; 145, 150) for axially displacing the sleeve relative to the pin selectively to expand and to permit reduction in the diameter of at least a portion of the outer surface of the sleeve.

1. A connector for joining a plurality of elements having attachment apertures therein comprising, pin means having radially extending head means and shank means extending axially from said head means positionable through all of the attachment apertures and having a tapering outer surface over at least a portion of the axial extent thereof, sleeve means insertable through all of the attachment apertures and having a tapering inner surface over at least a portion of the axial extent thereof for engaging said tapering outer surface of said pin means, a discontinuity in said sleeve means extending at least a portion of the axial extent thereof, and means for axially displacing said sleeve means relative to said pin means selectively to expand and to permit a reduction in the diameter of at least a portion of said sleeve means, wherein said means for axially displacing said sleeve means relative to said pin means includes collar means and fastener means extending through said collar means and threadably engaging said pin means. 2. A connector according to claim 1, wherein said head means and said collar means overlie a portion of the elements proximate to the attachment apertures. 3. A connector according to claim 1, wherein said tapering outer surface of said shank means extends substantially the entire axial extent thereof. 4. A connector according to claim 3, wherein said tapering outer surface of said shank means has a progressively smaller diameter from a position proximate said head means to the opposite axial extremity thereof. 5. A connector according to claim 1, wherein said tapering outer surface of said shank means has a progressively smaller diameter from the axial extremities thereof to an intermediate position. 6. A connector according to claim 5, wherein said tapering inner surface of said sleeve means has a progressively smaller diameter from the axial extremities thereof to an intermediate position. 7. A connector according to claim 1, wherein said head means of said pin means is formed integrally with said shank means. 8. A connector according to claim 7, wherein said pin means is formed in two parts and said means for axially displacing said sleeve means relative to said pin means includes fastener means extending through one of said two parts and engages a threaded bore in the other of said two parts. 9. A connector according to claim 1, wherein said discontinuity in said sleeve means is a through slot. 10. A connector according to claim 9, wherein said through slot extends the entire axial extent of said sleeve means. 11. A connecting pin for joining a pair of machine elements including a clevis with spaced legs having attachment apertures therein and a cylinder eye interposed between the spaced legs and having an attachment aperture therein comprising, pin means having radially extending head means, shank means on said pin means extending axially from said head means positionable through all of the attachment apertures and having a tapering outer surface axially thereof, sleeve means insertable through all of the attachment apertures and having a tapering inner surface axially thereof for engaging said tapering outer surface of said pin means, slot means in said sleeve means extending axially thereof, and fastener means extending through collar means and threadably engaging said pin means for axially relatively displacing said sleeve means and said pin means. 12. A connecting pin according to claim 11, wherein said head means and said collar means overlie a portion of the elements proximate to the attachment apertures. 13. A connecting pin according to claim 11, wherein said tapering outer surface of said shank means has a progressively smaller diameter from a position proximate said head means to the opposite axial extremity thereof. 14. A connecting pin according to claim 11, wherein said head means and said fastener means have flats to permit gripping by tools to facilitate relative rotation. 15. A connecting pin according to claim 11, wherein said collar means engages said sleeve means. 16. A connecting pin according to claim 11, wherein said collar means is attached to said pin means. 17. A connecting pin according to claim 11, wherein said radially extending head means and said collar means are larger than the attachment apertures in the spaced legs of the clevis and are positioned proximate thereto.
