Claim 1
Independent Claim
137 words
A differential handling tool for differentials having a flange thereon and a neck spaced in longitudinally therefrom: A. a support plate; B. a flange receiving means for said support plate; C. neck support means on the support plate; D. hold down means for securing the differential on the flange receiving and supporting means and the neck rest means; E. the flange receiving means including a pair of members extending laterally of the base plate and having oppositely arranged recesses for reception of the differential flange; F. said members comprising vertical, generally triangular body plates having their hypotenuse sides facing toward each other and the longitudinal center of the support plate; and G. and a channel member secured to the hypotenuse side of each body plate, said channel members defining the recesses for reception of the differential flange.
Claim 2
Dependent Claim
137 words
A differential handling tool for differentials having a flange thereon and a neck spaced in longitudinally therefrom: A. a support plate; B. a flange receiving means for said support plate; C. neck support means on the support plate; D. hold down means for securing the differential on the flange receiving and supporting means and the neck rest means; E. the flange receiving means including a pair of members extending laterally of the base plate and having oppositely arranged recesses for reception of the differential flange; F. said members comprising vertical, generally triangular body plates having their hypotenuse sides facing toward each other and the longitudinal center of the support plate; and G. and a channel member secured to the hypotenuse side of each body plate, said channel members defining the recesses for reception of the differential flange.
Claim 3
Dependent Claim
51 words
The invention defined by claim 1, including guide means defining a guide channel in which the bases of the triangular body plates are received and in which said body plates are adapted to slide toward and away from each other; and means for adjusting said body plates relative to each other.
Claim 4
Dependent Claim
185 words
A differential handling tool for differentials having a flange thereon and a neck spaced longitudinally therefrom: A. a support plate; B. flange receiving means for said support plate; C. neck support means on the support plate; D. hold down means for securing the differential on the flange receiving and supporting means and the neck rest means; E. said hold down means comprising an elongated flexible element having its ends connected to respective sides of the base plate and adapted to extend over a differential disposed on the flange receiving means and the neck support means; means for adjusting the effective length of the hold down means; F. there being a longitudinally extending side member along at least a portion of each side of the support plate, said longitudinally extending members having holes therein the holes of one of said members being aligned with corresponding holes in the other of said members; said elongated flexible element comprising a chain; hooks at the ends of said chain adapted to be hooked into holes of said side members; and G. a turnbuckle for tightening and loosening said chain.
