PROVISIONAL SPECIFICATION.
Improvements in Shoes or Slippers for Road Vehicles.
I, JOHN DRINKWATER ROBINSON, of No. 34 Osgathorpe Road, Pitsmoor, Sheffield,
in the County of York, General Carrier, do hereby declare the nature of my Invention
for "IMPROVEMENTS IN SHOES OR SLIPPERS FOR ROAD VEHICLES"
to be as
follows:-
Shoes or slippers for Road Vehicles have hitherto been constructed in one piece
so that when the sole or wearing part becomes too far worn for use, the whole
is discarded.
By my improved method of construction I make the shoe or slipper in two
parts, namely, an upper part which fits on to the wheel of the vehicle and a lower
part or sole which forms the wearing surface.
The upper part is made with a dovetailed recess or groove, on its lower surface,
tapering towards the trailing end, the lower part or sole being made with a
corresponding projection or tongue so that it may be inserted into the upper part,
being kept securely in position by the tapering of the recess or groove previously
referred to.
By this method of construction when the lower part or sole of the shoe or
slipper has become too far worn for use, it may be replaced by a fresh one at
less cost than by an entirely new shoe or slipper.
As a modification of the foregoing when the shoes or slippers are required to
be used in frosty weather the lower part or sole may be constructed with suitable
grooves, indentations or serrations on its wearing surface so as to increase the
friction of the same.
.
My improved shoes or slippers may be made in any suitable metal or metals or
metallic substance or material, that is to say, both parts may be made of the same
material, or one kind of material may be used for the upper part and another kind for
the lower part.
The essential feature of my Invention is the employment of interchangeable soles
or wearing parts of shoes or slippers for road vehicles substantially as herein
described.

Improvements in Shoes or Slippers for Road Vehicles.
I, JOHN DRINKWATER ROBINSON, of No. 34 Osgathorpe Road, Pitsmoor, Sheffield,
in the County of York, General Carrier, do hereby declare the nature of my
27 and
Invention for "IMPROVEMENTS IN SHOES OR SLIPPERS FOR ROAD VEHICLES
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :—
Shoes or slippers for Road vehicles have hitherto been constructed in one piece so
that when the sole or wearing part becomes too far worn for use, the whole is
discarded.
By my improved method of construction I make the shoe or slipper in two parts,
namely an upper part which fits on to the wheel of the vehicle and a lower part or
sole which forms the wearing surface.

page_text: referred to.
The upper part is made with a dovetailed recess or groove on its lower surface,
tapering towards the trailing end, the lower part or sole being made with a corre-
sponding projection or tongue so that it may be inserted into the upper part, being
kept securely in position by the tapering of the recess or groove previously
By this method of construction when the lower part or sole of the shoe or slipper
has become too far worn for use, may be replaced by a fresh one at less cost than
by an entirely new shoo or slipper.
As a modification of the foregoing when the shoes or slippers are required to be
used in frosty weather the lower part or solo may be constructed with suitable grooves,
indentations or serrations on its wearing surface so as to increase the friction of the
same.
My improved shoes or slippers may be made in any suitable metal or metals or
metallic substance or material, that is to say, both parts may be made of the same
material, or one kind of material may be used for the upper part and another kind for
the lower part.
The essential feature of my Invention is the employment of interchangeable soles
or wearing parts of shoes or slippers for road vehicles substantially as herein
describod.
The nature of my Invention will be better understood on reference to the accom-
panying sheet of drawings in which,
Fig. 1 represents a side view or elevation of my improved shoe or slipper the two
parts. being in position ready for use.
Fig. 2. being an end view of the same.
Fig. 3. represents the upper part of the shoe or slipper with the lower part or sole
removed.
Fig. 4. is an end view of the same.
Fig. 5. is a plan looking on the top and,
Fig. 6. is a plan looking on the bottom of the same, showing the groove or recess.
Fig. 7. is a side view or elevation of the lower part or sole as it appears detached
from the upper part.
Fig. 8. is an end view.
Fig. 9. is a plan showing the projection or tongue and
Fig., 10. is a plan showing the underside with a plain wearing surface on the
same.
Fig. 11. is a similar plan showing one of the methods of roughing the wearing
surface by means of grooves, indentations or serrations by which the friction of the
wearing surface may be increased.
募
The same letters refer to similar parts throughout the several views.
a, is the, upper part of the shoe or slipper.
b, is the lower part or sole of the same.
c, is the dovetailed recess or groove.
d, is the projection or tongue which fits into the groove.
e, is the trailing end of the shoe or slipper.
ff, are grooves indentations or serrations on the under surface of the sole.
As a modification of the mode of construction shown in the foregoing figures, the
projection or tongue, d, in the lower part or sole and the recess or groove, c, in, the
upper part of the shoe or slipper, may be made to extend for part of the length only
instead of the whole length as shown.
Having now particularly described and ascertained the nature of my Inven-
tion and in what manner the same is to be performed, I declare, that what I
claim is;
(1). Constructing the shoes or slippers for road vehicles in two parts viz. an upper
part which fits onto the wheel of the vehicle and a lower part or sole which forms the
wearing surface, such sole or wearing part being easily attached to or detached from
