A New or Improved Removable Tire, more especially applicable to
Road Vehicles.
I, HOWARD KERR, of Gate Pa, Tauranga, in the Bay of Plenty, in the Colony
of New Zealand, Retired Captain Royal Navy, 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 objects of my invention are to provide a tire which can be easily and
effectually fastened on to the wheels without heating; which can be taken off with
facility for renewal or repair, and the edges reversed when worn, also which can be
easily tightened when it has become loose through wear or exposure. A further
object of my invention is to provide such a tire as can be readily fastened on over
the present tires to renew them, or to increase the bearing surface, or form a
surface suitable for soft ground, and which can be fitted with bars or projections to
prevent slipping on slippery or frozen surfaces more especially in hilly countries.
My invention is illustrated in the accompanying drawing on which,
Figure 1 is a front view of the segment of an ordinary road carriage wheel
shewing my removable tire fixed over an ordinary tire so that either an ordinary
tire can be made use of or the removable tire be substituted for it.
Figure 2 is a sectional view of the same.
Figure 3 is a front view shewing my removable tire as fixed on the felloes of an
ordinary wheel, and having the same width and thickness as an ordinary tire.
Figure 4 shews the joint cover for the same.
Figures 5 & 6 shew an elevation and side view of a tire which prevents slipping
and can be fixed over the tire of a wheel as shewn in Figure 3 in place of a
smooth tire.
Figure 7 is a front view of the segment of an ordinary road vehicle wheel fitted
with a broad removable tire fixed over the usual tire and having strengthening
ribs. The ordinary tire or the removable tire can be made use of as desired.
Figure 8 is a sectional view of the same.
Figure 9 is an elevation of the screw press for squeezing the tires to the felloes.
Figure 10 is a wrench for tightening the bolts.
(a) in Figures 1 & 2 are the ordinary felloes of a wheel having a nave (a¹).
(b) is the ordinary tire. (c) is my removable tire divided at (c¹). (c²) is a lug or
projection formed on the tire (c) as shewn which is slotted so that the bolt (3) may
pass through it and move freely within it. (c) is a lug or projection tapped to
receive the screw (c³). (c) is the head of the bolt (e) drilled (by preference) with
holes to suit the outer end of a wrench shewn in Figure 10.
(d) are clamps formed or fastened on to the removable tire (c) and drawn
together around the felloe (a) and secured by the bolt (d').
By this description of the several parts and by reference to the drawings will
be seen my method of attaching a new and wider tire to a wheel having an
ordinary tire and securely fastening the same in such a manner that it can be
tightened or removed when desired."
(a) in Figure 3 are the ordinary felloes of a wheel having a nave (a¹). (e) is a
metal box let into the felloes and firmly screwed into its place so as to form a
chamber for the lugs (c²) & (c) and screw bolt (c³) which are similar to those
hereinbefore described for Figures 1 & 2.
This chamber is covered by a plate shewn in Figure 4. (f) are plates placed
on each side of the tire and screwed both to the edge of the tire (g) and the face
of the felloes (a). These plates (f) are more suitable when the tire is constructed

page_text: in segments but if in one piece ordinary bolts can be passed through tire and
fellne.
By these means I secure to a wheel a tire made in two segments or in one piece
of the ordinary width and which is readily removable. In fixing this tire to
wood felloes I find it desirable to make use of the press shewn in Figure 9 to
squeeze the tires to the felloes (a), as the plates (f) are being fastened, or the usual
screws are driven.
Figures 5 & 6 shew a form of tire suitable for the wheel shewn in Figure 1 when
the wheels are used in slippery places.
(a) in Figures 7 & 8 are the ordinary felloes of a wheel having a tire (h) fitted
with strengthening ribs (¹) which extend inwards and support the felloes (a).
This wheel bas clips (d) similar to those in Figures 1 & 2 but fewer in number and
also screw bolt (3), but the lugs (c²) & (c) are widened so as to form ribs also to
strengthen the tire.
This tire is placed over the tire of an ordinary wheel and is used to broaden the
wheel so as to be useful for heavy work. It will be evident that my removable
tires may be of steel, wrought iron, cast iron, or any suitable material.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is,―
1. A removable tire (c) made in sections, having lugs such as (c²) & (c) fitted
with tightening bolts such as (c³) and also clips such as (d) as and for the purposes
substantially as described herein and illustrated in Figures 1 & 2.
2. A removable tire (9) made in sections, having lugs such as (c²) & (c) fitted
with tightening bolts such as (c³) and chamber such as (e) with supports such as (f)
or the ordinary screws as and for the purposes substantially as described herein and
illustrated in Figure 3.
3. A removable tire having projections or ribs as shewn in Figures 5 & 6.
4. A removable tire (h) having strengthening ribs (1) clips (d) lugs (c²) & (c¹)
fitted with bolts (3) as and for the purposes substantially as described herein and
illustrated in Figures 1 & 2.
