We, NICHOLAS ROSENBLATT, and SERGIUS AIISCHARUMOFF, of Liteiny 49, St.
Petersburg, Russia, do hereby declare the nature of this invention to be as
follows:-
Our invention relates to improvements in rubber tyres for vehicles.
In carrying out our invention we employ a rim or felloe of suitable form
adapted to hold the rubber tyre in place. This tyre may have a groove or a
number of recesses on its inner face with which recesses communicate other holes
at right angles thereto such holes passing through the rubber to the outer face
or tread in which may be formed if desired recesses communicating therewith.
Through the holes at right angles to the length of the tyre are placed the shanks
of studs or headed pins or plates the heads of which may seat in the recesses in
the outer face or tread while the inner ends of the shanks may be split so as to
be turned down over a washer or otherwise as desired such turned portions seat-
ing in the recesses in the inner face, the arrangement being such that the studs
may move up and down with the compression of the rubber. Or in place of the
split ends the studs may be held in the rubber in other ways. The heads of the
studs are preferably slightly convex on the head side or they may be of other
shapes. The arrangement affords a more or less complete metallic tread while
also providing a cushioned wheel which will not throw mud sideways as is the
case with ordinary rubber tyres.

We, NICHOLAS ROSENBLATT, and SERGIUS ASCHARUMOFF, of Liteiny 49, St.

manner the same is to be performed, to be particularly described and ascertained:
in and by the following statement: --

or tread in which may be formed if desired recesses communicating therewith.
Through the holes at right angles to the length of the tyre are placed the shanks
of studs or headed pins or plates the heads of which may seat in the recesses in
the outer face or tread while the inner ends of the shanks may be split so as to
be turned down over a washer or otherwise as desired such turned portions seat-
ing in the recesses in the inner face,, the arrangement being such that the studs
may move up and down with the compression of the rubber. Or in place of the
split ends the studs may be held in the rubber in other ways. The heads of the
studs are preferably slightly convex on the head side or they may be of other
shapes. The arrangement, affords a more or less complete metallic tread while
also providing a cushioned wheel which will not throw mud sideways as is the
case with ordinary rubber tyres.
In order that the invention may be clearly understood reference is made to the
accompanying drawings in which Fig. 1 represents a vertical section of a part
of a wheel provided with an elastic tyre; Figs. 2 and 3fare front and side viewś
respectively of a metallic pin having a large head and forming part of the tyre;
Fig. 4 is a top view partly in section of the pin; Fig.
represents a face view of
the tyre as it would appear.if laid out in a horizontal plane.
The metallic rim à may be of ordinary form, as shown it partially embraces
with its sides 6 the elastic tyre c. The tyre is provided with a groove or series
of recesses d on its inner face. Through the tyre c, at suitable intervals are
radial perforations equal in diameter to the external diameter of the pins which
are inserted in these perforations the outer face of the tyre may be formed with
shallow cavities corresponding in form to the inner face of the heads f of the
pins at the points where such heads will rest.
The metallic pins are split on the upper or inner ends the external surfaces
of the heads being slightly convex and normally protruding beyond the surface
of the tyre c.
The split ends, of the pins v after being inserted in the tyre, are
bent outwardly as at'm, m.
⚫ is a socket for the spoke of the wheel.
It will be seen that by the use of this invention the elastic tyre does not come
into immediate contact with the ground while the benefit of its clasticity and
resiliency are secured.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is;
I
In tyres for carriages and other vehicles, and in combination an elastic tyre,
pins inserted in said tyre and having large, slightly convex heads which project
beyond the external surface of the tyre, and means for holding such pins to the
tyres, substantially as described.
