It is desirable to afford at least substantial universal movement of the lifting eye relative to the engine. An example of such a lifting eye is disclosed in US. Pat. No. 3,297,293.
SUMMARY OF THIS INVENTION An object of this invention is to provide a noncomplex and economical lifting eye arrangement adapted for attachment to an engine. The lifting eye comprises a pair of annular members each comprising a base portion and a cylindrical hub portion with such hub portions being disposed in back-to-back relationship to define an annular groove on the periphery of the members. A ring member is rotatably mounted in the groove and has a pair of diametrically opposed projections extending radially outwardly therefrom and a U-shaped lifting eye is pivotally mounted on the projections.
BRIEF DESCRIPTION OF THE DRAWING Other objects of this invention will become apparent from the following description and accompanying drawing wherein:
FIG. I is a sectioned front elevational view of a lifting eye arrangement of this invention, attached to an engine block;
FIGS. 2 and 3 are views taken in the direction of arrows II-II and III-III in FIG. 1, respectively; and
FIG. 4 illustrates design parameters for the lifting eye arrangement.
DETAILED DESCRIPTION FIGS. l-3 illustrate a lifting eye arrangement of this invention releasably attached to an engine block 11 by a single bolt 12 disposed on a central longitudinal axis X thereof. Such arrangement comprises a pair of substantially identical annular members 13 each having an annular base portion 14 and a cylindrical hub portion 15 formed integrally on one side thereof. The members are disposed in back-toback relationship to have the hub portions thereof abut each other at flat bearing surfaces 16.
A flat annular bearing surface 17 of the base portion of the lower one of the members abuts a flat upper surface 18 of the engine block to provide a substantial bearing contact therebetween. The outside diameter of each hub portion 15 is substantially less than the corresponding outside diameter or dimension of a respective base portion 14 to thus define a common annular groove 19 circumferentially about the hub portions and axially between the base portions. An annular ring member 20 is rotatably mounted in the groove and has a pair of diametrically opposed and integrally formed lifting lugs or cylindrical bearings 21 projecting radially outwardly thereform beyond members 13.
A downwardly extending flange 22 is integrally formed on the outer end of each lug to define a notch 23 on the underside of the lug. radially between the main body portion of ring member 20 and the flange. A U-shaped lifting eye 24 has a pair of parallel legs 25 and 26 each having a respective flange 22 mounted on an outboard side thereof and each defining an elongated slot 27 therethrough. The lifting eye is mounted on the lugs of ring member 20 at such slots prior to projection of bolt 12 through aligned bore 28 formed through members 13 and securance of the bolt to the engine block.
To facilitate such lateral mounting, it should be noted in FIG. 4 that the axial length L, of each slot 27 is slightly greater than the axial length L; of each flange 22. Furthermore, the axial distance D between the lower end of each flange 22 and bearing surface 17, is
preferably less than the axial distance D between a lower end of slot 27 and bearing surface 17. Such construction and arrangement will prevent removal of the lifting eye laterally past either one of flanges 22 upon installation of the lifting eye arrangement on the engine.
I claim:
1. A lifting eye arrangement disposed on a central longitudinal axis thereof and adapted for attachment to an engine block or the like comprising a pair of annular members each comprising a base portion and a cylindrical hub portion formed integrally on one side of said base portion. the outside diameter of each of said hub portions being substantially less than the corresponding outside dimension of a respective base portion.
the hub portions of said members disposed in backto-back relationship to define a common annular groove circumferentially about said hub portions and axially between said base portions,
a ring member rotatably mounted in said groove and having a pair of diametrically opposed lugs extending radially outwardly therefrom beyond said members,

2. The lifting eye arrangement of claim I wherein said members are at least substantially identical and said lugs are formed integrally therewith.
3. The lifting eye arrangement of claim I wherein said hub portions abut at flat surface portions thereof.
4. The lifting eye arrangement of claim 1 wherein one side of a base portion of at least one of said members. opposite to the side thereof having said hub portion formed thereon, is flat to provide a substantial bearing surface thereat.
5. The lifting eye arrangement of claim 1 wherein each of said lugs comprises a cylindrical bearing.
6. The lifting eye arrangement of claim 1 further comprising a notch defined on an underside of each of said lugs. radially between a respective flange and said ring member.
attaching said lifting eye arrangement to a flat surface of said engine at the flat side of a lower one of said members.
9. The lifting eye arrangement of claim 8 wherein said fastening means comprises a single bolt projecting through aligned bores formed axially through said members and threadably attached to said engine.
