Improvements relating to Wheel Tires.
I EDMUND FRANCIS ELDREDGE of New York, State of New York, United States of
America, Gentleman 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 :-
My invention relates especially to devices employed on the wheels of carriages,
buggies etc. to deaden the noise produced in driving over hard or rough surfaces and
to contribute to the ease of the motion of the vehicle.
To attain the desired end my invention consists essentially of a tire made of india-
rubber or equivalent material said tyre having in its centre a steel core, perforated for
the reception of bolts or screws for securing the rubber tire to a metal tire concave
upon its outer face, and flat upon its interior for the purpose of firmly holding the tyre
and at the same time permitting my improvement to be applied to any style of
existing wheel, and my invention also involves certain other novel and useful com-
binations or arrangements of parts and peculiarities of construction and operation all
of which will be hereinafter first fully described and then pointed out in the
claims.
In the drawings Fig. 1 in a plan view of a vehicle wheel wherewith my improve-
ment is employed. Fig. 2 is a cross sectional view at line of Fig. 1. Fig. 3 is a
cross sectional view illustrating a method of securing the tire to the wheel and Fig. 4
is a cross sectional view at line y y illustrating a hidden method of securing the tire to
the wheel.
Like letters of reference indicate corresponding parts in all the figures.
A is the hub of the wheel and B the spokes C are the fellies, Dis the ordinary iron
or steel tire E is a tire of steel having its inner face flat and its outer face concave, as
particularly illustrated in Figs. 2. 3 and 4.
F is a rubber tire preferably ovoid in form and containing a steel core G having
screw threaded perforations therein at short intervals for the reception of screws or
bolts H which pass through the steel tire E. By this construction the rubber is
rigidly held against possibility of stretching and cannot become loose and the steel
tire E holding the rubber against any lateral or side movement.
In applying my improved tire to the ordinary wheel, if the tire D is rounded upon
its edges through wear, the wheel may be placed in a lathe and trued up upon its face
and holes bored through the tire and fellies at intervals around the wheel. The proper
size of steel tire E bearing its rubber face F is then passed thereover and if it is desired
to permanently secure my rubber tire in place springs L are inserted in each perfora-
tion and pins K thereover, thus when the tire is slipped into place, the pins K will be
forced into the perforations in the tire E holding the same in place. When desired
the perforations may be made to pass entirely through the fellies and screws M used
as illustrated in Fig. 3.
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. The combination with a vehicle wheel provided with a metal tire of a solid metal
tire and a rubber tire ovoid in cross section and provided with a continuous metal
core perforated for the reception of fastening bolts by which it is secured to the solid
metal tire said metal tire being concave upon its outer face and flat within and having
its edges at right angles to its inner face and upon the same plan as the tire of the
vehicle wheel substantially as shown and described.

page_text: 2. The combination with a rubber tire constructed and arranged as set forth and
having perforations in the metal tire to which the rubber is secured, of concealed
holding devices within the fellies, adapted to enter said perforations substantially as
shown and described.
3. A rubber tire having a core of metal a metal tire to which said rubber is secured
said metal tire being perforated as set forth the fellies of a wheel having perforations
which coincide with the perforations in the metal tire and spring actuated radial pins
located in said perforations the whole combined and arranged substantially as shown
and described.
