PROVISIONAL SPECIFICATION.
Improvements in connection with Wheels and Brakes suitable for
Autocars and other Vehicles.
We, HENRY SINGLETON CARR, of 4 Sydenham Place, Otley Road, Bradford, in the
County of York, and ERNEST SCHUTT, of 5 Manor Row, Bradford, aforesaid, Machinists,
do hereby declare the nature of this invention to be as follows:-
This invention has for its object the arrangement and combination with wheels
suitable for autocars and other vehicles of certain mechanism arranged and applied in
such a inanner so as to prevent the wheels of the vehicle skidding or sliding on hard
frosted and slippery ground, also to so arrange the same that the vehicle is better
enabled to ascend a gradient in such weather and to arrange and combine with the
vehicle, brakes for engaging with the slippery ground which are so constructed as
to prevent the sliding or skidding and retard the progress of the vehicle.
In carrying out our invention we attach to the rim or other convenient portion of
the wheel a circular plate having a number of inclined plains formed thereon, resting
upon each of which is a bar made sharp at the outer end, each bar being retained in
its required position by a plate and spring or the like.
On turning the before mentioned circular plate round in either direction, the
before mentioned bars are made to protrude some distance beyond the circumference
of the wheel, or are liberated so that they may be pressed back facable with the
surface of the rim or tyre of the wheel, the circular plate being held in its required
position by a pawl or other means applied to and connected with some portion of the
wheel. When the pointed bars protrude, the sharp ends engage with the hard frosted
ground, and thereby prevent the vehicle slipping. On the release of the pawl or the
like the circular plate is liberated and can be moved back to its original position.
The brake shoe is arranged with a number of prongs and the shoe is operated by
means of levers in a manner that when breaking or retarding the progress of the
vehicle, the prongs are made to engage with the hard frosted slippery ground.

performed, to be particularly described and ascertained in and by the following
statement:-
E.
This invention has for its object, the arrangement and combination with wheels
suitable for autocars and other vehicles, of certain mechanism arranged and applied
in such a manner, so as to prevent the wheels of the vehicle skidding or sliding on
hard, frosted and slippery ground; also to so arrange the mechanism that, the vehicle
is better enabled to ascend a gradient in such weather, and to arrange and combine
with the vehicle, brakes for engaging with the slippery ground, by so constructing.
them as to prevent the sliding or skidding and retard the progress of the vehicle.
In describing our invention in detail, reference is made to the accompanying sheet
of drawings, in which Fig. 1 represents a front elevation of a wheel arranged
according to our invention.
Fig. 2 is a side elevation of a car provided with our improved brake, and to which
the hind wheels arranged according to our invention are fitted.
Fig. 3 is a detached detail of a bar and spring fitted around the wheel, a portion of
the bar is cut away to show the recess or spring bed, and
Fig. 4 is a detached detail of our brake shoe.
In carrying out our invention we attach to the rim A. or other convenient portion
of the wheel, a circular plate B. arranged and shown in the drawings to pass through
the arms or spokes C. of the wheel, but the said plate may be supported by staple
plates attached to the spokes or to the rim A. of the wheel. In the circular plate B.
one or more slot holes D. may be cut and a pin E. passed through the respective
spokes or staple plates as the case may be, and around the outer circumference of the
circular plate B. a number of inclined planes F. are formed, resting upon each of
which is a bar G. made sharp at the outer end at G. each bar passing through the
rim A. and retained therein by a pin H. in the respective bars near to the inner
circumference of the wheel rim A.
In order that the bars G. may retain the required position in the rim A, that is to
say so that they do not project beyond the distance propelled by the inclined planes,
each bar G. is recessed and provided with a plate spring J. shrunk into the recess in a
manner that, on the expansion of the spring J. the bars are pressed against the rim
and retained by friction.
On turning the before mentioned circular plate round in either direction, the
bars G. are made to protrude some distance beyond the circumference of the wheel,
or they are liberated, so that they may be pressed back until the outer ends at G¹.
are facable with the circumference or tyre of the wheel, the circular plate B. being
held in its required position by a pawl K. mounted to a bracket attached to the
wheel rim.
The circular plate B. may be moved in its path by means of a light lever arranged
in the form, of a crank, one end of which is placed in a hole L. in the rim, the arm of
the lever engaging with a peg or pin M. so that on applying pressure to the lever and
pin, the circular plate is moved a distance that the pawl K. engages with another
notch N. or it may be released therefrom, and the spiral springs O. allowed to contract
and move the said circular plate to the position that the ends of the bars G. rest in
the bottom of the respective inclined planes.
By arranging the hind or driving wheels of the autocar in the manner described,
there is no possibility of the vehicle skidding as the pointed bars G. engage with the
frosted surface, also by the said pointed bars engaging with the frosted slippery
ground the wheels will not slip on ascending a gradient to such an extent, as is the
case with wheels having smooth tyres, thus enabling the vehicle to ascend more
rapidly.
The brake may consist of one or more shoes P. each secured by a rod to a lever
mounted on a shaft supported by a bracket Q, the lever R. is secured to the said
shaft and operated by the hand wheel and screw shaft as shown, but it will be obvious
that the lever in place of the screw may be utilized for operating the brake shoe or
shoes and bringing them into contact with, or away from the slippery ground, the

ground.
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed; we declare that what
we claim is:-
1. A wheel provided with a number of pointed bars G. operated by a circular
plate C. mounted and arranged substantially in the manner as shown and described
and for the purpose as herein before set forth.
2. The combination with a vehicle of one or more brake shoes P. provided with
prongs for the purpose as herein before set forth.
