Abstract
Abstract A ball stud removing tool for removing a ball from a stud on which it is press-fitted, wherein a cup-shaped shield surrounds the stud adjacent the ball; comprising a first member having an externally threaded upper end and a yoke-shaped lower end, the free ends of the yoke being dimensioned to embraceably engage the ball below its diameter so that it may be pulled from the stud. A second sleeve-like member is received over the first member after assembly of the latter on the ball, its threaded portion extending through an aperture in the upper sleeve end. An internally threaded nut is then threaded onto the first member, which is thereby retracted into the sleeve, drawing the ball from the stud.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
192 words
A tool for removing a ball from a stud upon which the ball is press-fitted, wherein a cup-shaped shield surrounds the stud in the area adjacent the ball, comprising a first member having a threaded upper end and a bifurcated lower end defining a pair of rigid parallel arms spaced throughout a major portion of their length a distance greater than the ball diameter, the free ends of said arms having inwardly extending protuberances defining arcuately shaped surface portions conforming to the curvature of said ball and adapted to embraceably support the ball therebetween, a second sleeve-like member slidably receivable over said first member and insertable within said cup-shaped shield, said second member having a partially closed upper end apertured to receive said threaded end of the first member, and nut means threadably engageable with said first member threaded end, said first member being tiltably receivable within said shield with said arms thereof embracing said ball and thereafter rotatable into alignment with the stud axis for reception of said second member, whereby the ball may be withdrawn from the stud by threaded engagement of said nut with said first member threaded length.
Claim 2
Dependent Claim

A tool for removing a ball from a stud upon which the ball is press-fitted, wherein a cup-shaped shield surrounds the stud in the area adjacent the ball, comprising a first member having a threaded upper end and a bifurcated lower end defining a pair of rigid parallel arms spaced throughout a major portion of their length a distance greater than the ball diameter, the free ends of said arms having inwardly extending protuberances defining arcuately shaped surface portions conforming to the curvature of said ball and adapted to embraceably support the ball therebetween, a second sleeve-like member slidably receivable over said first member and insertable within said cup-shaped shield, said second member having a partially closed upper end apertured to receive said threaded end of the first member, and nut means threadably engageable with said first member threaded end, said first member being tiltably receivable within said shield with said arms thereof embracing said ball and thereafter rotatable into alignment with the stud axis for reception of said second member, whereby the ball may be withdrawn from the stud by threaded engagement of said nut with said first member threaded length.
Claim 3
Dependent Claim
49 words
A tool as defined in claim 1 characterized in that said first member has an upper extremity surmounting said threaded length having a cross-sectional area less than said threaded length for reception of said nut means thereover, said extremity defining opposed flats engageable by a wrench or the like.
Claim 4
Dependent Claim
37 words
A tool as defined in claim 1 characterized in that said stud and cup-shaped shield are fixed to a support, said sleeve-like member having a lower end portion receivable through the shield into abutment with said support.
Claim 5
Dependent Claim
40 words
A tool as defined in claim 1 characterized in that said free ends of said arms of said first member terminate in arcuately shaped extremities extending transverse the longitudinal axis of the member and within the plane of said arms.
