PROVISIONAL SPECIFICATION.
Improved Apparatus for Starting Oars and like Vehiclės.
WALTER REGINALD LAMBERT 41 Whitbread Road Brockley S.E. Electrical
Engineer do hereby declare the nature of this invention to be as follows:-
The object of my invention is to facilitate the starting of cars and like vehicles.
It is carried out as follows:-
Upon the axle or any suitable part of the under frame I pivot a lever, the
opposite end of which is attached in any suitable manner to the drawn bar, which is
coupled up to a draw spring and furnished with a stop.
A pawl or knuckle jointed finger is so hinged to the lever as to engage with
teeth upon the periphery of a pinion, or the wheel or wheels keyed to the axle.
A suitable arrangement is provided, whereby the pawl or knuckle jointed finger
can be turned in the proper direction for starting into motion a vehicle such as a
tram car, or railway wagon, or carriage drawn from either end; but this is omitted
in the case of a vehicle travelling in one direction only.
The operation of my invention is as follows:-
The motive power being coupled to the draw hook, a greatly increased pull is
exerted upon the lever carrying the pawl engaging with the pinion or wheel teeth
upon the axle, and the car is started into motion. The draw spring now reacts,
lifting the finger out of gear, this position being retained by the direction of rotation
of the wheel.
It is obvious that the position of the pawl upon the lever can be so adjusted as to
obtain any desired power.

COMPLETE SPECIFICATION.
Improved Apparatus for Starting Cars and like Vehicles.
WALTER REGINALD LAMBERT 41 Whitbread Road Brockley, S.E. Electrical
Engineer, 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 my invention is to facilitate the starting of cars and like vehicles.
It is carried out as follows:-
Upon the axle or any suitable part of the under frame I pivot a lever, the
opposite end of which is attached in any suitable manner to the draw bar, which is
coupled up to a draw spring, and furnished with a stop. A pawl or knuckle jointed
finger is so hinged to the lever as to engage with teeth upon the periphery of a
pinion or the wheel or wheels keyed to the axle. A suitable arrangement is
provided whereby the pawl or knuckle jointed finger can be turned in the proper
direction for starting into motion a vehicle such as a tram car, or railway wagon,
or carriage drawn from either end; but this is omitted in the case of a vehicle
travelling in one direction only. The operation of my invention is as follows:--
The motive power being coupled to the draw hook, a greatly increased pull is
exerted upon the lever carrying the pawl engaging with the pinion or wheel teeth
upon the axle, and the car is started into motion. The draw spring now reacts

page_text: lifting the finger out of gear, this position being retained by the direction of
rotation of the wheel.
It is obvious that the po: tion of the pawl upon the lever can be so adjusted as to
obtain any desired power.
To enable my invention to be clearly understood I will now describe the same by
means of the accompanying drawings in which-
Fig. 1. is a part front elevation, and Fig. 2. is a part side view of an ordinary road
wagon, fitted with my invention.
Fig. 3. shews my invention as applied to a road car drawn from either end.
In the drawing, a is the body of vehicle, b the wheel, c the hub, d the axle, e the
fore carriage, the turntable, g the spring. Mounted upon the axle d, is a rocking
lever, upon which is pivoted an L shaped lever i, to one end of lever i, is pivoted
an arm, having at its lower end a hinged pawl k, which engages when the parts
are in the position shewn with the ratchet wheel l, keyed to the hub c of the wheel b.
The upper end of lever i, and of lever h, have eyes m m' formed in them, and
through these eyes passes the draw bar n, to which the traces are attached in the
usual manner, a pin o, passes through the eye m', the lever i, and the draw bar n,
to which is fitted an iron shoe p, on which is shut a collar q, the extreme end being
drilled in order that the spring, may be attached to it, the other end of this
spring being anchored to the fore carriage e. The respective parts of the apparatus
are shewn in the position they occupy when a pull is exerted upon the draw bar,
and the pawl k, is in the act of forcing round the ratchet wheel 1, secured to the
wheel. So long as the full strain is exerted upon the draw bar n, the pawl k, is by
the rotation of the ratchet wheel, lifted out of gear; but upon relaxing the strain,
or upon stoppage of the vehicle the spring r, draws back the draw bar n, and the
lever i, lifting the pawl k, clear of the teeth of the ratchet 1, as shewn in the right
hand drawing in Fig. 3, so that the vehicle can be backed.
Upon a pull being again exerted upon draw bar n, the lever i, first lowers the
pawl into the tooth of the ratchet wheel beneath it, see Fig. 2 and then by the
action of collar y, attached to the draw bar shoe p, enables the rocking lever h, to
force round the ratchet. wheel, and start the vehicle. The size of the ratchet
wheel may be varied so as to permit of greater or less leverage upon it by the
rocking lever h. The apparatus producing the result described is fitted to both
wheels of either a two or four wheeled vehicle.
Fig. 3. shews the application of my invention to a road car or other similar single
carriage or wagon drawn from either end. In this case the ratchet 1 is preferably
keyed at about the centre of each revolving axle d, to which the wheels bare
keyed.
The ratchets may however be mounted if convenient upon one and the same axle.
In the left hand drawing, the parts are in the position they occupy when the pawl
is in the act of starting the vehicle; the right hand figure shewing the pawl out of
gear as previously described under Fig. 2.
my
It is obvious that alterations in detail may be made to suit varying types of two
or four wheeled carriages of either class without departing from the spirit of
invention as for instance the ratchet wheel shewn upon the axle in Fig. 3 may
form part of, or be keyed to the hub, spokes or disc of the wheel; the rocking lever
being mounted either upon the hub or the axle as may be convenient, suitable con-
nections being made for connecting the draw bar thereto.
Having now particularly described and ascertained the nature of my said inveu-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The improved combination of parts herein described, actuated by the draw
bar for starting two or four wheeled vehicles into motion from a condition of
absolute or partial rest.
2. In apparatus for starting vehicles into motion from a condition of absolute or

page_text: and
partial rest, the combination of the levers h, rocking upon the axle d or hubs
carrying the pivoted shaped lever i, actuating the arm j, the hinged pawl k which
drives the toothed wheel 1, secured to the wheel or axle, by means of the draw bar n,
collar o, lever h, and spring r, in the way and manner described.
3. In apparatus for starting into motion vehicles hauled from either end, the
combination and arrangement of parts described under Fig. 3 operating upon one
and the same or separate axles as described.
