PROVISIONAL SPECIFICATION.
Improvements in and in connection with Wheel-jacks, applicable to
Vehicles generally.
I, HARVEY HEAD MATHEW WEST of Prince of Wales" Oxford Road
Wind-or Innkeeper do hereby declare the nature of this invention to be as
1:
The object of this invention is to make the wheel jack self locking, and also easily
adapted for small and large wheels without the removal of any of the parts.
For this purpose, construct a base and upright of any convenient shape and
dimensions of either wood or metal. The upright is either slotted for the greater
part of its length or constructed of two parallel bars or posts, in or between which
the lever works. In the longer arm of the lever a slot of any length is formed,
along both sides of which, teeth or notches are cut where required, the shorter arm
is either curved or cut away to any desired shape to receive the axle of the vehicle.
This lever is pivotted to the upper end of the upright or main support. To any
part of the upright a metal or other loop is pivotted which loop passes through the
slot in the longer arm of the lever handle. When using the jack, both hands may
be used to raise the wheel, as the loop engages in the teeth or notches in the slot,
locking the lever at any required height. To adjust the jack for either large or
small wheels, the lever is simply reversed on its pivot, the long and short arms thus
changing positions, without removing any part or bolt, the action of the lever being
the same on either side. The whole inay be constructed in detachable parts for
convenience of storage.

"
I, HARVEY HEAD MATHEW WEST, of The Prince of Wales" Oxford Road
Windsor Innkeeper, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
The object of this invention is to construct a wheel jack that shall be self locking
in any position, easily adapted for both large and small wheels without the removal
of any of its parts, and also convenient for storage or transport, all its several parts
being detachable.
In
For this purpose I construct a base of any convenient shape and dimensions.
any part of this base, but preferably near the centre, a hole or socket is cut, in
which the ends of an upright or standard fits. This upright should be constructed
preferably in one piece, being slotted from the top downwards for the greater part
of its length, in this slotted portion of the upright the lifting lever works, the same
being pivotted at or near the upper end of the standard or upright. The upright is
firmly affixed to the base by means of a suitably formed rod or bar fitting over the
solid part below the slot, and extending any requisite distance on either side to the
base to which it is firmly bolted preferably by means of thumb screws or other like
method. In the longer arm of this lifting lever a slot is formed of any required
length, along both sides of which any number of teeth or notches are cut.

The

page_text: shorter arm of the lever is cut or formed into any convenient shape to receive the
axles of either small or large vehicles, and covered where required with india rubber
or other like substance to prevent slipping, and consequent damage to painted or
polished surfaces. To any part of the standard or upright, but preferably near the
base, a loop of iron or other suitable metal is pivotted, this loop being formed of
such a length as to pass free over the top of the standard to which it is pivotted.
This metal loop passes through the slot formed in the longer arm of the lifting lever.
By the use of this my invention both hands are free and can be used to raise the
vehicle, as when at the required height by releasing the lever, the loop engages
automatically in the teeth or notches in the same, thus locking the lever in any
position.
The adjustment of the jack for large or small wheels is very simple, the lever
being reversed from one side to the other on its pivot, each part thus changing
positions without the removal of a single bolt, the locking action of the lever and
loop being the same on either side. By the removal of the four bolts by which the
whole apparatus is held together, the several parts become detachable, and may be
packed for transit or storage in small compass. The base, upright, and lever, may
be made of either wood or metal as required. In the accompanying drawings,
Fig. 1 represents a side elevation, and Fig. 2, an end elevation of my invention, in
both of which the same letters refer to corresponding parts. A is the base on which
the standard B is fitted. C is the lever pivotted at the bolt D, in the longer arm
of which, the slot E (Fig. 1), with the teeth or notches F F is formed in which the
Joop Gengages as shown at II (Fig. 1). I. I. are the rubber coverings for
preventing slipping and damage to the vehicle to be lifted. The upright standard B
is held firmly in position by the bent iron stay rod which is bolted to the base
as shown by the bolts or screws K, K. The foop G is pivotted on the bolt L. The
movements of the various parts in reversing the lever is shown by the dotted lines
in Fig. 1. By the removal of the nuts and bolts K, K, D and L which are
preferably fitted with thumbscrews or flynuts, every part of the apparatus becomes
detachable, and can be packed flat with the base board occupying but little space.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is :-
1. The self locking arrangement applied to wheel jacks as hercin set forth, and
illustrated.
2. The adjustable and detachable wheel jack constructed in the manner, as herein
set forth, described & illustrated.
Dated this 29th day of May 1891.
