in order to afford the requisiteu'igidity to the standards 28 and 29 aud to frevent their s reading under'j the stl-esa r'ol-v supporting tile load, I,prefe'rably provideo liquely'dis posed stay-rods 32 and *33 connected to the socket members'24 and 25 and to thestand:

To facilitate the rotary movement of the'lifting elements as ju'st'described, I have found it expedient to provide each standard at its-lowefex tremity with a wheel or roller, such', forex ample, as shown in Fig.5, wherein :ncaster 35 having a shank. 36 .the standard37 'iseinployed, a cotter pin 38 the revolution of the Seated'. inthe base'of passlng'through the exposed portion of the a shank of the caster dislodgment thereof.

It 'wilhbeunanifest that in addition to the eflicncy of my invention as a jack or lifting device'in making roadside repairs or adjustments, itfalso 1s perticu irly edvnntugeous as a substitute for turn-teb1es, such as are now employed in garage equipment. By the provision of swiveled rollers,

such as'illustrated in Fig. 5, when the vehicle has been jacked up, as shown in Fig. 4, it may be readily moved in any direction to facilitate storage, cleenin and the like. in the latter connection, if esired, the veunauthorized use by locking the pawl 40 in engagement with the ratchet 39 by meens'of a pad-lock, shown at 45, passing throu h e as 46 an '47; as shown in Fig. 7. y t is means, it will be evident that no one but possessing the key to the lock will torestore the lifting elements to make use of the'vehicle,

There are many other avenues of use for my invention and it is obvious that there may be immy changes made in structural details without departing from the spirit and scope of my invention, the application herein shown being simply employed for the purpose of furnishing a clear and comgmal iensi ve description.
