Abstract
Abstract An attachment for use with a conventional jack which jack includes a base portion and a ram portion carried therein and adapted to move relative to the base portion along the longitudinal axis thereof. The jack attachment includes a socket member having a cavity formed therein for receiving the ram portion of the jack. An elongated member having opposite end portions is fixedly secured at one end portion to the socket member and extends therefrom in axial alignment with the longitudinal axis of the jack and includes a transverse notch formed in the opposite end thereof. A second elongated member having opposite end portions includes a cavity intersecting one end portion thereof sized and shaped to receive the first elongated member therein and includes a flat plate formed on the opposite end portion thereof lying in a plane substantially normal to the longitudinal axis of the jack. An L-shaped edge portion is formed along one edge of the flat plate. In another form, the present invention includes a socket member for receiving the ram portion of the jack and further includes a second socket member formed thereon extending away from the jack. The second socket member has a cavity formed therein sized and shaped to receive one end portion of a first elongated member with the opposite end portion of the first elongated member having a transverse notch formed therein. An alternate second elongated member has a substantially flat plate formed on the opposite end thereof lying in a plane substantially normal to the longitudinal axis of the jack and having an L-shaped edge portion formed along one edge thereof.

Claim 1
Independent Claim
185 words
A jack attachment for use with a conventional jack of the type which includes a base portion and a ram portion, having an upper end, adapted to move relative to the base portion along a longitudinal axis comprising: socket means sized and shaped for longitudinally slidably receiving the end of the ram portion therein into abutting relation; a first extension fixedly secured at one end thereof to said socket means and extending therefrom in substantial axial alignment with the longitudinal axis of the jack, said first extension comprising: a socket formed in the opposite end portion thereof; an elongated member having a first end portion slidably received in said socket and abutting said socket means and having the opposite end portion thereof extending from said socket means in substantial axial alignment with the longitudinal axis of the jack; and means for engaging the object to be moved formed on the opposite end portion of said elongated member, said means comprising a transverse notch formed in the opposite end portion of said elongated member, said notch being substantially normal to the longitudinal axis of the jack.
Claim 2
Dependent Claim
185 words
A jack attachment for use with a conventional jack of the type which includes a base portion and a ram portion, having an upper end, adapted to move relative to the base portion along a longitudinal axis comprising: socket means sized and shaped for longitudinally slidably receiving the end of the ram portion therein into abutting relation; a first extension fixedly secured at one end thereof to said socket means and extending therefrom in substantial axial alignment with the longitudinal axis of the jack, said first extension comprising: a socket formed in the opposite end portion thereof; an elongated member having a first end portion slidably received in said socket and abutting said socket means and having the opposite end portion thereof extending from said socket means in substantial axial alignment with the longitudinal axis of the jack; and means for engaging the object to be moved formed on the opposite end portion of said elongated member, said means comprising a transverse notch formed in the opposite end portion of said elongated member, said notch being substantially normal to the longitudinal axis of the jack.
