Improvements in the Tyres of Wheels.
FRANK STANLEY WILLOUGHBY, 12, Mosley Street, Manchester, Merchant, do
hereby declare the nature of this invention to be as follows:-
My invention has reference to the Patent granted to me No. 21760/9 and is an
improvement in the formation of the clasped on shoes or protective armour with
which under that patent the face of the rubber round a wheel is covered.
According to my present invention I in lieu of shaping the ends of the shoes
rectangular to their sides form them more or less on the slant for example if looked
at from the top or face the shape is that of a parallelogram with acute and obtuse
argles in contradistinction to a right angled parallelogram.
Another form is where the clasped on shoes are furnished at their ends with
protruding pieces and corresponding hollows, the protruding piece in one shoe
engaging the hollow in its neighbour so arranged that while the resilient or
inward movement of the tyre is not destroyed the lateral displacement of an
individual shoe is prevented.
Another form is where the clasped on shoes are flexibly united to each other by
pins placed transversely through their engaged ends which in this application
may take somewhat the form of links the shoes being thus formed into a chain
like armour capable of resilient or inward movement but prevented from individual
lateral displacement, but inasmuch as the sides of this chain are also turned
inwards it is secured to the rubber by its clasp and does not depend upon its con-
tinuity to keep it in its place on the rublier, such continuity however, is of
assistance in the case where an excessive side strain happens to come upon an
individual shoe.
Another form is where the ends of the shoes instead of being shaped to butt-end
to each other are shaped slanting in a vertical direction so that the slanting end
of one overlaps the slanting end of its neighbour this will prevent the tilting
of the aft end of a shoe when the fore end comes in contact with the ground as the
wheel revolves. Looked at from the side the shape of these shoes is that of a
parallelogram with acute and obtuse angles in contradistinction to a right angled
parallelogram. This slant in a vertical direction may be used in combination
with the transverse slanting and other forms previously described and also in the
case where the shoes are flexibly united by transverse pins.

page_text: performed, to be particularly described and ascertained in and by the following
statement:-
My invention has reference to the Patent granted to me No. 21760/ and consists
in a special formation of the clasped on "shoes or protective armour with which
under that patent the face of the rubber round a wheel is covered.
According to my present invention I in lieu of shaping the ends of the shoes
rectangular to their sides as in Figure 1 form them more or less on the slant as in
Figure 2 for example if looked at from the top or face the shape is that of a
parallelogram with acute and obtuse angles in contradistinction to a right angled
parallelogram.

Another form is where the clasped on shoes are furnished at their ends with
protruding pieces and, corresponding hollows, the protruding piece in one shoe
engaging the hollow in its neighbour as in Figures 3, 4 and 5 so arranged that
while the resilient or inward movement of the tyre is not destroyed the lateral.
displacement of an individual shoe is either prevented or rendered more difficult.
Another form is where the, ends of the shoes; instead, of being shaped to butt-
end to each other as in Figure 1 are shaped slanting in a. vertical .rection as in
Figure 6 so that the slanting end of one overlaps the slanting end of its neighbour
this will prevent the tilting of the aft end of a shoe when the fore end comes in
contact with the ground as the wheel revolves. Looked at from the side the shape
of these shoes is that of a parallelogram with acute and obtuse angles in contra-
distinction to a right angled parallelogram. This slant in a vertical direction
may be used in combination with the transverse slanting and other forms
previously described and illustrated in Figures 2, 3, 4, and 5.,
Having now particularly described and ascertained the nature of my invention 1
declare that what I claim is:-
The application to or combination with the rubber tyre of any wheel of short
detached metallic shoes or wearing plates of the improved shape or configuration
herein described, and substantially illustrated, such improved shape shoes being
secured to the rubber by being clasped thereon by their inturned edges in the
manner fully described and illustrated in my Patent No. 21760-1892.
Dated this 10th day of September 1897.
