Abstract
Abstract An automatic tilting safety transmission adapter base assembly for facilitating removal and installation of vehicle transmissions. The apparatus is comprised of upper and lower contiguous plate members having hinge means and stop means arranged in a manner respective of a jack head mount means which enables the assembly to be removably affixed to a jack head, and the upper plate member to be affixed to a transmission by bolts, so that the transmission can be removed at an angle relative to the vehicle and which avoids side loads being imparted into the jack. The stop means are located adjacent the hinge means and prevents the contiguous plate members from pivoting away from one another an amount which would allow the center of gravity of the transmission to pass over center of the adaptor base.

Claim 1
Independent Claim
251 words
An automatic tilting safety transmission adapter base assembly for removing and installing vehicle transmissions comprising upper and lower contiguous plate members, hinge means pivotally connecting a marginal edge portion of said contiguous plate members together so that the plate members are free to be pivotally moved respective to one another; stop means connected to said assembly for limiting the angular displacement of one plate member away from the other, said plate members being free to pivot toward and away from one another within the limits of said stop member; a jack head mount means for removably securing said lower plate member to the head of a jack assembly; a plurality of elongate swingable brackets, means forming spaced apertures in said brackets; one aperture being for attachment to a transmission; a plurality of apertures formed in the marginal hinged end portion of said upper plate, bolt means swingably securing one apertured portion of said bracket to said upper plate; and a cut-out in the hinged end of said lower plate member for enabling the plates to be pivoted together with the lower plate member freely clearing said bracket and said bolt means; whereby: said base assembly can be affixed to a jack head by said jack head mount means, said brackets can be affixed to a transmission, and the transmission can be removed or replaced respective of a vehicle while the plate members freely pivot apart so that the transmission can assume an angular disposition relative to the vehicle and the jack.

An automatic tilting safety transmission adapter base assembly for removing and installing vehicle transmissions comprising upper and lower contiguous plate members, hinge means pivotally connecting a marginal edge portion of said contiguous plate members together so that the plate members are free to be pivotally moved respective to one another; stop means connected to said assembly for limiting the angular displacement of one plate member away from the other, said plate members being free to pivot toward and away from one another within the limits of said stop member; a jack head mount means for removably securing said lower plate member to the head of a jack assembly; a plurality of elongate swingable brackets, means forming spaced apertures in said brackets; one aperture being for attachment to a transmission; a plurality of apertures formed in the marginal hinged end portion of said upper plate, bolt means swingably securing one apertured portion of said bracket to said upper plate; and a cut-out in the hinged end of said lower plate member for enabling the plates to be pivoted together with the lower plate member freely clearing said bracket and said bolt means; whereby: said base assembly can be affixed to a jack head by said jack head mount means, said brackets can be affixed to a transmission, and the transmission can be removed or replaced respective of a vehicle while the plate members freely pivot apart so that the transmission can assume an angular disposition relative to the vehicle and the jack.
Claim 3
Dependent Claim
49 words
The apparatus of claim 1 wherein said stop means is affixed to said upper plate, said stop means having a vertical downwardly disposed wall from which there is affixed an inwardly directed wall which abuttingly receives the lower plate thereagainst when the upper plate member is pivoted away therefrom.
Claim 4
Dependent Claim
49 words
The apparatus of claim 2 wherein said vertical downwardly disposed wall includes a continuation thereof which is apertured to form part of said hinge means, a pin attached to said lower plate means, said pin having a free end portion extending through said continuation of said downwardly disposed wall.
Claim 5
Dependent Claim
30 words
The apparatus of claim 2 wherein said lower plate member has a pin welded thereto which extends outwardly therefrom and into engagement with said vertical wall form said hinge means.
Claim 6
Dependent Claim
68 words
The apparatus of claim 2 wherein said upper plate member has a series of apertures formed in the area which is superimposed upon said cut-out when the plates are brought into abutting engagement, so that a fastener means can be placed within one said aperture and affixed to one said bracket to theReby enable a transmission to be removably fastened to the upper plate member by said bracket.
Claim 7
Dependent Claim
58 words
The apparatus of claim 2 wherein said upper plate is provided with apertures at the end opposed to said hinge means and said lower plate member is shortened relative to said upper plate at the end opposed to said hinge means to enable the lower plate member to freely clear the brackets placed in the last said apertures.
Claim 8
Dependent Claim
42 words
The apparatus of claim 6 wherein the free marginal end portion of said lower plate member is in the form of a truncated triangle, to provide a working area for brackets which are attached to opposed sides of the upper plate member.
Claim 9
Dependent Claim
42 words
The apparatus of claim 2 wherein said inwardly directed wall of said stop means is inclined relative to said upper plate means, with said inclined wall being parallel to said lower plate when said lower plate member abutingly engages the inclined wall.
