Warehouse and Platform Trucks and other similar Vehicles.
I, ALFRED DUGDALE of 61 Plymouth Grove Manchester Engineer do hereby
declare the nature of this invention to be as follows:-
My invention has for its object the construction of truck wheels with elastic tires
protected by metal bands or rims which while giving an elastic tread shall not
increase the draught, nor subject the rubber or other elastic material used, to the
wear occasioned by contact with the ground or floor.
This I propose to effect by making the wheels of metal or a combination of wood
and metal and with one fast and one loose flange. I fit these wheels with rings of
rubber, or I use a length of coiled rubber, preferably of square or rectangular
section, and wrap it round the periphery of the wheel and cut it to the length
necessary to encircle it. This rubber may be made hollow by having a hole
through it longitudinally to lighten it and give it greater resiliency.
I then place the rubber inside a metal tire or ring made with an internal channel
or groove of suitable size and shape to receive it and place this combined metal
and rubber tire on to the wheel and I attach the loose flange to the principal part
of the wheel by bolts, screws or rivets, in such a manner as to hold the rubber tire
between the two flanges.
Dated this 27th day of December 1895.

Improvements in or applicable to the Construction of Wheels for
Warehouse and Platform Trucks and other similar Vehicles.
I, ALFRED DUGDALE of 61 Plymouth Grove, Manchester, Engineer do bereby
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 the construction of truck wheels with elastic
tires protected by metal bands or rims which while giving an elastic tread shall not
increase the draught, nor subject the rubber or other elastic material used, to the
wear occasioned by contact with the ground or floor.
This I propose to effect by making the wheels of metal or a combination of wood
and metal, and with one fast and one loose flange. I fit these wheels with rings of
rubber or, I use a length of spirally coiled rubber preferably of square or
rectangular section and wrap it round the periphery of the wheel and cut it to the
length necessary to encircle it. This rubber may be made hollow by having a hole
through it longitudinally to lighten it and give it greater resiliency.

page_text: I then place the rubber inside a metal tire or ring made with an internal channel
or groove of suitable size and shape to receive it, and place this combined metal
and rubber tire on to the wheel, and I attach the loose flange to the principal part
of the wheel by bolts screws or rivets in such manner as to hold the rubber tire
between the two flanges, or I make the wheel in halves each with a flange on it, and
bolt them together with the metal and rubber tire between them.
The nature of my said invention and the manner in which the same is to be
carried into practical effect will be readily understood on reference to the drawing
hereunto annexed and the following explanation thereof.
The drawing represents a transverse section of a part of the wheel when fitted
with the protecting metal tire.
A is the outer metal protecting ring or tire.
B is the rubber ring inserted into the channel of ring A.
C is the principal or main part of the wheel with a fixed flange.
D is the loose flange, which is attached to C by bolts one of which is
-shown at E.
In putting the wheel together I first take the rubber ring B, or a length of
rubber sufficient to encircle the body of the wheel and spring it into the channel
of the metal ring A, and place it upon the wheel as shown in the aunexed drawing,
-and then I attach the loose flange D to the main part of the wheel by bolts, screws
or rivets as may be convenient.
Having now particularly described and ascertained the nature of my inveu-
tion and the manner in which same is to be performed, I declare that what 1
.claim is :
The method of applying an outer metal tire for the protection of the rubber and
elastic tires of truck wheels, in combination with a flanged wheel made in halves or
with a loose flange, substantially as hereinbefore described and illustrated by the
drawing annexed.
Dated this 29th day of September 1896.
