Patent Images
1. For use in a connection between a drive coupling and a tang end of a pump drive member, an adaptor comprising:
- (a) a bifurcation at one end of said adaptor to enable said adaptor to engage a tang end of such a drive member;
(b) mutually inwardly facing flats one on each part of said bifurcation, for engagement with opposite sides of such a tang end; and
(c) outwardly facing flats, one on each part of said bifurcation, to engage mutually facing flats of an elongate hole or recess in a part of such a coupling; and
(d) a circularly cross-sectioned opposite end of said adaptor to enable that end to be located in a hole or recess of corresponding circular cross-section in such a coupling whereby an axis of the coupling is aligned with that of the pump drive member.

Abstract
An adaptor for use in connecting a drive coupling to a non-splined end of a pump shaft. The adaptor has means at one end thereof for connecting the adaptor to the end of the pump shaft, at least one flat by which the drive coupling can be made rotationally fast with the adaptor, and an opposite end of circular cross-section for location in a hole or recess of corresponding circular cross-section in the drive coupling to align an axis of the coupling with that of the pump shaft.
