Abstract
Abstract An apparatus for safely jacking up a portion of a vehicle for common maintenance work or to change a tire and the like, the apparatus comprising at least one adaptor bracket secured to the frame of the vehicle at the position at which it is desired to engage the jack thereto, and a screw-type jack having a sleeve adapted for telescoping movement about a threaded shaft in a vertical direction with the bottom end of the shaft pivotally secured to a self-aligning base for adjusting to various types and inclinations of ground surfaces on which the jack is rested, and with the outer cylindrical sleeve of the jack having a collar affixed thereto with a lifting arm pivotally attached at one end to the collar with the other end projecting radially outwardly from the collar and adapted to be engaged in a recess provided therefor in the adaptor bracket for safely elevating the vehicle in a jacking type movement. The pivot axis of the self-aligning base is normal to the axis of the lifting arm such that when in use the jack is self-aligning on the base in a direction toward and away from the vehicle to assure positive engagement of the lifting arm with the bracket.

Claim 1
Independent Claim
379 words
Jacking apparatus intended for use with a vehicle for the safe and positive jacking of the vehicle to an elevated position for performance of maintenance on the vehicle, changing a tire of the vehicle, and the like, the apparatus comprising: at least one lifting adaptor bracket affixed to the frame of the vehicle and having a front end and a back end, the front end projecting outwardly of the vehicle and defining a recess therein; a screw type jack having a threaded shaft with a tubular cylindrical sleeve member telescopically received on said shaft for reciprocal movement therealong, a handle operatively attached to the jack to effect the reciprocal movement of the sleeve member; a self-aligning jack base member affixed to the bottom end of said jack and adapted to engage a supporting surface in a selfaligning manner for support of the jack thereon; and a lifting arm having one end affixed to said jack sleeve member with the opposite end projecting outwardly therefrom and adapted to engage said recess of said lifting adaptor bracket and operable in a manner to elevate the vehicle by means of said bracket when said sleeve member is moved vertically upwardly along said threaded shaft of said jack; said lifting adaptor bracket comprising an elongated body member haviNg an inverted substantially U-shaped cross-section formed of a horizontal base member and depending vertically downwardly projecting leg portions, said base member and said leg portions defining interiorly thereof the elongated slot forming recess, said body member having a front end and a back end, a hardened steel pin spaced inwardly from said front end a substantial distance and extending intermediate said leg portions, a supporting member having one end affixed to said back end portion of said body member with the opposite end projecting substantially vertically upwardly therefrom and adapted to be secured to a portion of the frame of said vehicle, a second support member having one end affixed to the front end portion of said body member with the opposite end projecting upwardly therefrom and adapted to engage a rigid portion of said vehicle and selected from the portions including the vehicle bumper, the vehicle frame, and the like whereby the front end of said body member is directed outwardly of said vehicle.

Jacking apparatus intended for use with a vehicle for the safe and positive jacking of the vehicle to an elevated position for performance of maintenance on the vehicle, changing a tire of the vehicle, and the like, the apparatus comprising: at least one lifting adaptor bracket affixed to the frame of the vehicle and having a front end and a back end, the front end projecting outwardly of the vehicle and defining a recess therein; a screw type jack having a threaded shaft with a tubular cylindrical sleeve member telescopically received on said shaft for reciprocal movement therealong, a handle operatively attached to the jack to effect the reciprocal movement of the sleeve member; a self-aligning jack base member affixed to the bottom end of said jack and adapted to engage a supporting surface in a selfaligning manner for support of the jack thereon; and a lifting arm having one end affixed to said jack sleeve member with the opposite end projecting outwardly therefrom and adapted to engage said recess of said lifting adaptor bracket and operable in a manner to elevate the vehicle by means of said bracket when said sleeve member is moved vertically upwardly along said threaded shaft of said jack; said lifting adaptor bracket comprising an elongated body member haviNg an inverted substantially U-shaped cross-section formed of a horizontal base member and depending vertically downwardly projecting leg portions, said base member and said leg portions defining interiorly thereof the elongated slot forming recess, said body member having a front end and a back end, a hardened steel pin spaced inwardly from said front end a substantial distance and extending intermediate said leg portions, a supporting member having one end affixed to said back end portion of said body member with the opposite end projecting substantially vertically upwardly therefrom and adapted to be secured to a portion of the frame of said vehicle, a second support member having one end affixed to the front end portion of said body member with the opposite end projecting upwardly therefrom and adapted to engage a rigid portion of said vehicle and selected from the portions including the vehicle bumper, the vehicle frame, and the like whereby the front end of said body member is directed outwardly of said vehicle.
Claim 3
Dependent Claim
248 words
The apparatus as set forth in claim 1 wherein said sleeve member is provided with an annular collar member affixed thereto and spaced a slight distance upwardly from the bottom end thereof, a pair of flange members affixed to said collar member and projecting radially outwardly therefrom in a direction adapted to be pointed toward said lifting adaptor bracket when the jack is in operative position relative thereto, one end of said lifting arm disposed intermediate said flange arm portions and pivotally connected thereto by a pivot pin extending through the flange portions and lifting arm in a direction normal to the axis of the sleeve member, the opposite end of the lifting arm projecting outwardly therefrom and swingable about said pivot between a storage position disposed adjacent to said sleeve member side wall surfaces and an operative position extending radially outwardly of said sleeve member, a flange member affixed to the bottom surface of said lifting arm, a brace member having one end pivotally affixed to said lifting arm bottom flange with the opposite end projecting away therefrom and pivotable thereabout, a socket member defined on said sleeve member adjacent the bottom end thereof and formed in the plane of movement of said lifting arm, the free end of said brace member adapted to be engaged in said socket member when said lifting arm is in the operative position projecting outwardly of said sleeve member for engagement with said body member slot of said lifting adaptor bracket.
Claim 4
Dependent Claim
91 words
The apparatus as set forth in claim 2 wherein the outer end portion of said lifting arm is provided with a recess in the lower lip portion thereof, and wherein said lifting adaptor bracket body member is provided with a hardened steel pin spaced inwardly of said bracket front end and extending transversely between said bracket leg portions, said recess adapted to engage said pin to indicate the proper position of insertion of said lifting arm into said slot preparatory to the lifting of the vehicle by operation of said jack.
Claim 5
Dependent Claim
112 words
The apparatus as set forth in claim 3 wherein said self-aligning base member is comprised of a substantially flat platform adapted to be rested on a ground surface or the like, a flange member affixed centrally of said platform and projecting vertically outwardly from the top surface thereof, and said bottom end of said shaft being pivotally connected to said platform base portion by a pivot pin extending through said flange portion and said bottom end shaft portion in a direction normal to the plane of movement of said lifting arm whereby said jack is pivotable relative to said base in a direction toward and away from the vehicle to be elevated.
