PROVISIONAL SPECIFICATION.
Improvements in or applicable to the Tyres or Rims of Wheeled
Vehicles.
:-
I, JOHN FRANCIS HALL of Norbury, Sheffield in the County of York, Steel
Works Manager, do hereby declare the nature of my invention to be as follows:-
This invention has for its object to give the wheels of traction engines, wagons,
and other vehicles a better grip upon the roadway and to enable the wheels of
vehicles to more readily leave the sunk lines or metals of tramways.
I propose to attach thereto, or form upon the face of the tyre, or the rim of the
wheel when a tyre is not used, any given number of grips or "shoes," of a con-
figuration which may vary from a V to a U. With grips or shoes so constructed
the wheel has a much better hold of the roadway, and has not the same tendency
to cut up the road as when fitted with straight strips placed diagonally.
When the shoes are V shaped, and are used upon narrow wheels they tend to
lift the wheels out of the sunk tramway lines.
Dated the 3rd day of July 1891.

COMPLETE SPECIFICATION.
Improvements in or applicable to the Tyres or Rims of Wheeled
Vehicles.
I, JOHN FRANCIS HALL of Norbury, Sheffield, in the County of York, Steel
Works Manager, 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 :-
This invention has for its object to give the wheels of traction engines, wagons
and other vehicles by means of grips or shoes a better grip or hold upon the road-
way, and also to enable the wheels of vehicles to readily leave the sunk lines or
flange-grooves of tramway lines.
I have illustrated my invention in the annexed sheet of drawings in which
Fig. 1, plan and edge view of a piece of tyre with detachable grips or shoes
pointed or angular.
Fig. 2, similar views with solid grips.
Fig. 3, similar views, showing detachable arched grips.
Fig. 4 similar views, showing solid arched grips.
Figs. 5 and 6, showing double grips pointed and arched.
In carrying out my invention I form upon the face of the tyre A, and either solid
therewith as shown in Fig. 2, or attached thereto as in Fig. 1, any desired number
of grips or shoes, either of angular or pointed form as those marked B, Figs. 1
and 2, or of a curved or arched form as those marked C, Figs. 3 and 4, or of any
form modified between the two, or of either of the said forms multiplied in the
manner shown in Figs. 5 and 6. With tyres having shoes or grips so constructed
the wheels of a vehicle have a much better hold of the road, and have not the
same tendency to cut up the roadway as the diagonally placed straight bars.
When the grips are angular as shown in Figs. 1 and 2, and are used upon narrow
wheels they are useful in lifting the wheels out of the sunk tramway lines.
The clips may be rolled solid with the tyres and therefore be of the same

page_text: material, or they may be stamped, rolled or cast of steel and be secured to the tyre
either permanently by rivets or so that they can be detached and replaced.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same may be put into practice, I declare that what I
claim is :-
1-A wheel tyre or rim for vehicles provided with. angular or arched grips or
shoes, either solid with the tyre or attached thereto substantially as hereinbefore
described and shown in the drawings.
2-A grip or shoe of angular or arched form secured to the tyre or rim of a
wheel for the purpose specified and substantially as herein before described, and
illustrated in the drawings annexed hereto.
Dated the 31st day of March 1892.
