Abstract
Abstract There is disclosed a vehicle transporting apparatus comprising a mounting for attachment to the rear of a transporting vehicle, a rearwardly extending boom one end of which is pivotally connected to the mounting for up and down swinging movement of the boom on the mounting, the free end of the boom having mounted thereon two supports for the wheels of a vehicle to be transported, which supports are spaced horizontally apart in a direction transverse to the direction of travel of the vehicle, power means connected to the boom to effect swinging movement thereof between a loading position where the supports rest on the ground, a transporting position where the supports are raised a short distance above the ground, and a stowed position where the boom extends upwardly from the mounting, and releasable detent means between the boom and the mounting to retain the boom in one or more of said positions.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
230 words
A vehicle-transporting apparatus comprising in combination: a. a mounting for attachment to the rear of a towing vehicle, b. a longitudinally extending boom the forward end of which is pivotally connected to the mounting by a boom pivot, c. a hydraulic ram between the boom and the mounting to effect up and down swinging movement of said boom about said boom pivot, d. two supports, mounted adjacent the rearward end of the boom and spaced apart across said boom for receiving the wheels of a vehicle to be transported, e. said ram having its line of action on the other side of said boom pivot said supports, f. releasable detent means between the boom and the mounting to retain said boom alternatively in a loading position in which said supports rest on the ground, a transporting position in which said supports are raised a short distance from the ground, and a stowed position in which said boom extends upwardly from said mounting further said detent means comprise a movable catch member on one of said boom and said mounting engagable with an abutment fixed relatively to the other of said boom and mounting, and said movable catch member further comprises a pivotally mounted lever, pivotal movement of which swings one end thereof into an operative position in which it is engagable with said abutment upon swinging movement of said boom.
Claim 2
Dependent Claim
230 words
A vehicle-transporting apparatus comprising in combination: a. a mounting for attachment to the rear of a towing vehicle, b. a longitudinally extending boom the forward end of which is pivotally connected to the mounting by a boom pivot, c. a hydraulic ram between the boom and the mounting to effect up and down swinging movement of said boom about said boom pivot, d. two supports, mounted adjacent the rearward end of the boom and spaced apart across said boom for receiving the wheels of a vehicle to be transported, e. said ram having its line of action on the other side of said boom pivot said supports, f. releasable detent means between the boom and the mounting to retain said boom alternatively in a loading position in which said supports rest on the ground, a transporting position in which said supports are raised a short distance from the ground, and a stowed position in which said boom extends upwardly from said mounting further said detent means comprise a movable catch member on one of said boom and said mounting engagable with an abutment fixed relatively to the other of said boom and mounting, and said movable catch member further comprises a pivotally mounted lever, pivotal movement of which swings one end thereof into an operative position in which it is engagable with said abutment upon swinging movement of said boom.
Claim 3
Dependent Claim
39 words
The apparatus of claim 1 wherein there is provided a manipulating member, a part of which is operatively connected to the other end of said lever and is movable linearly in a direction to effect pivoting of said lever.
Claim 4
Dependent Claim
36 words
The apparatus of claim 2 in which said lever is spring-urged towards its said operative position, said manipulating member being arranged to pivot said lever to an inoperative position against the action of the spring means.
Claim 5
Dependent Claim
24 words
The apparatus of claim 3 in which said catch member is incorporated in the boom and said abutment is fixed relative to said mounting.
