IMPROVEMENTS IN REMOVEABLE TYRES FOR THE WHEELS OF VEHICLES."
Year: 1882

page_text: LETTERS PATENT to John Haynes, of Silkstone Common, near Barnsley, in
the County of York, for an invention of "IMPROVEMENTS IN REMOVEABLE
TYRES FOR THE WHEELS OF VEHICLES."
PROVISIONAL SPECIFICATION left by the said John Haynes at the Office of
the Commissioners of Patents on the 18th March 1882.
JOHN HAYNES of Silkstone Common, near Barnsley, in the County of York.
"IMPROVEMENTS IN REMOVEABLE TYRES FOR THE WHEELS OF VEHICLES."
My invention relates to improvements in removeable tyres for the wheels of
Vehicles more especially those vehicles which may be used for farming and other
similar purposes, and which are required to run on the soft land or soil as well as
on the macadamised roads, and the object of my invention is to provide a light
tyre that shall be easy of application and attachment to the ordinary wheels of
carts and other similar vehicles, and that shall be of greater width than the tyres
of such ordinary wheels and thus by increasing the bearing surface, shall prevent
the wheels from sinking into the soft earth and thus avoid causing undue labour
to the horse.
In carrying out one arrangement of my invention as applied to the wheels of a
cart for farming purposes (for example) I make the removeable tyre in two parts
or halves or it may be in a single piece of a 5 section, or other very similar
section Each part of the removeable tyre is provided with suitable lugs attached
to the inside of the outer or projecting flanges and fitted with Screws-bolts and
nuts, or their equivalents so that they can be readily drawn together and securely
tightened and held upon the wheel of the cart.
The central groove or annular recess receiving the ordinary tyre or rim of the
wheel, and the outer flanges projecting on each side of the wheel.
By this arrangement when the wheel is on the hard road it runs upon the
central or narrow projecting part of the tyre, but when upon soft soil, it sinks till
it rests upon the broader flanges, and is thus prevented from sinking deeper into
the earth and thereby cutting up the land, and putting heavy work upon the horse.
In a second arrangement of my invention the moveable tyre may be made flat on
the outside, and with two flanges or ribs on the inside (TT) the rim of the cart
wheel being held between the said flanges and secured in a similar way to that
hereinbefore described.
My Invention is also applicable to Bicycles, Tricycles, and similar carriages
which may be required to run on the sands at the seaside, or upon other soft
ground.

"IMPROVEMENTS IN REMOVEABLE TYRES FOR THE WHEELS OF VEHICLES
"
My Invention relates to improvements in removeable Tyres for the wheels of
Vehicles and more especially for Carts and Wagons used for farming purposes and
other similar work, and which are often required to run alternately on macadamised
roads, and on soft land or cultivated soil-and the object of my invention is to
provide removeable tyres that shall be easy of application and attachment to the
ordinary wheels of such carts or other vehicles, (so that a Farming man or
labourer may attach them without the aid of a Smith or Mechanic) and that shall
be of greater width than the ordinary wheels to which they are to be applied, and
thus by increasing the area of the bearing surface shall offer greater resistance, and
thus prevent the wheels from sinking into and cutting up the soil, as well as
affording relief to the animal.
use,
My Invention of removeable tyres which may be readily attached for occasional
and afterwards be removed; in contradistinction to the fixed or permanent
tyres of vehicles is also applicable to Bicycles, Tricycles and similar carriages to
enable them to be used on the sands at the sea side, or upon other soft ground,
and in order that my invention may be fully understood I will now refer to the
annexed sheet of Drawings simply premising that the same letters of reference
indicate the same or equivalent parts in all the figures Fig: 1 represents a
removeable tyre of the section as shown on an enlarged scale in Fig: 2.
Fig 3 shows the plan of tightening up an securing it.
j
Figs 4 and 5 represent a tyre of a different section and Fig: 6, a plan of
tightening and securing the same. Fig: 7 represents a tyre made from a flat bar
with intermittant lugs or stays rivetted or screwed on, instead of a continuous
flange as in Figs; 4 and 5. Fig; 8 shows a section of same. Fig; 9 represents a
piece of light tyre suitable for a Bicycle or Tricycle.
In carrying out my invention as applicable to Carts and similar wheeled Vehicles,
I form a tyre preferably by rolling, of the section as shown in Fig; 2 having a
recess or groove A to fit onto or over the ordinary tyre of the wheel, and with two
flanges B B of any desired width, a good proportion being to make each flange of
the same width as the groove A.
The tyre may be made in a single piece (or in halves) and after being sprung
over the wheel, can be tightened on the wheel, and firmly secured by the means
shown at C in Figure 1, and enlarged in Fig; 3. D and D₁ are two lugs rivetted
or secured by other means to the flanges B of the tyre, E is a screw passing
through a slotted hole in the lug D and screwing into the tapped hole in D-but
a bolt or wedged cottar or similar device may be used.
This tyre is most suitable where the Vehicle is required to run alternately on
hard and soft ground, as on the hard ground the wheel runs on the narrow part of
the tyre at A, but when on soft ground it sinks till it rests on the flanges B B.
The tyre as shown in Fig: 4 is made of the section as in Fig; 5 having two
internal flanges F F, either formed out of the solid or separately and attached to G,
thus offering a broad flat surface at G to the ground-The fastening shown enlarged
in Fig; 6 is formed of two brackets H provided with slots and stays I I, the
BCrew E works through two nuts J, J, which are provided with side lugs to
prevent them turning round when tightening up the screw E they are also rounded

page_text: on the inside, so that they may always bed solid to the brackets H-The fastenings
as above described and shown in Figs, 3 and 6 may be used for either of the
sections as described.
The tyre shown in Fig: 7 can be made from a plain flat tyre bar, any desired
number of the lugs K being securely fastened to the inside of the tyre-either of
the fastenings before described may be used.
For Bicycles and similar Carriages the Tyre shown in Fig; 9 is most suitable-
I prefer to make it of thin sheet steel rolled to this section, the trough L is to
cover the rubber tyre of the Bicycle-Fastenings as before described may be used
to secure this tyre which may be made in one piece.
Having now described and fully ascertained the nature of my said invention and
the manner in which it may be carried into effect I would observe in conclusion
that what I consider to be novel and original and therefore claim as secured to
me by the herein before in part recited Letters Patent is-
Removeable Tyres for temporary attachment to the ordinary wheels of Vehicles
more particularly Carts and Wagons used for farming and similar purposes which
are required to travel alternately on hard and soft ground and for Bicycles and
Tricycles and similar carriages for running on the sands and other soft ground,
substantially as hereinbefore described and illustrated or any mere modification
thereof.
In witness whereof I the said John Haynes have hereunto set my hand
and seal this Second day of September in the year of our Lord One thousand
eight hundred and eighty two.
