COMPLETE SPECIFICATION.
An Improvement in Cushioned Car-wheels.
I, BENJAMIN FRANKLIN HAUGH, of 670 North Pennsylvania Street, in India-
napolis, County of Marion, State of Indiana and United States of America,
Car-wheel Manufacturer, 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 to an improvement in cushioned car wheels, and it has for its
object to provide means whereby the elasticity or cushioning capacity of the wheel
will be increased, and also to provide a suitable guard or shield for protecting the
cushion from the oil or drippings that flow from the oil-box of the axle, said guard
arranged to contact with the inner edge of the flange of the tire to form a safety
stop, and will be hereinafter more fully described.
attain these objects by means of the arrangement of the wheel illustrated in
the accompanying drawings, in which ;-
Fig. 1. is a part elevation of the outer face of the wheel or the face next to the
oil-box, showing the outwardly flaring flange for deflecting the waste oil from the
joint between the tire flange and the centre of the wheel.
Fig. 2. is a section of the same through the line (see Figs. 1. & 3.) and,
Fig. 3. is a part elevation of the inner face of the wheel.
Similar numbers of reference designate like parts throughout the several views.
1. designates the centre or main body of the wheel (preferably of steel) having
the hub 2, and the peripheral flange 3. formed thereon and integral therewith and
provided for the purpose of relieving the flange of the tire from any undue or
excessive stress that may be brought to bear upon it, as by a longitudinal blow.
4. designates the tire of the wheel having its tread of the usual or any suitable
form, and provided at or near its outer face and on the face opposite its flange 5.
with the annular and inwardly projecting flange 6. formed integral thereon, said
flange having its inner edge tapered or flared outwardly as shown particularly in
Fig. 2. for the purpose hereinafter more fully described.
Between the bearing peripheries of the flange 3. and the tire 4. is interposed the
cushion 8. (preferably of rubber or other flexible composition) which completely
encircles said centre and extends entirely across the face thereof.
9. designates the shield encircling the outer periphery of the cushion for the
purpose of protecting it from abrasion or wrinkling when forcing the tire over it
and on its centre.
11. designates the outer shield or guard of the wheel centre which is formed
integral on the outer face thereof and having its inner surface flared outwardly
from the outer face of said centre which is provided for the purpose of deflecting
the waste oil from the joint between the flange 6. of the tire and the centre 1. thus
effectually directing the flow of the waste oil outwardly and protecting the cushion
from any oil that might gradually work or ooze through said joint.
It has been found in practice, that, in order to increase the elasticity of the wheel
and consequently its cushioning capacity, the elastic cushion 8. should extend
entirely across the face or bearing periphery of the centre 1. thus bringing said
cushion into close proximity to the joint between the flange 6. of the tire and said
centre 1.
It is evident that this construction of wheel would afford a ready means for the
admission of waste oil to the cushion through the joint 5* were there no means
provided to intercept its flow which would soon destroy said cushion by reducing it
to a plastic condition, for this reason and in order to prevent such I provide the
annular deflecting flange 11. hereinbefore described for the purpose of deflecting

page_text: the said waste oil from said joint 5ª. For the same reason the inner peripheral
edge 10. of the flange 6. is flared outwardly and should correspond with the
inclination of the flare of the inner surface of the flange 11.
The outer periphery of the flange 11. and the inner peripheral edge 10. of the
flange 6. being of like inclination or taper, and the space between these inclined
surfaces being slightly less than the play of the securing rivets 12. in their holes
formed in the flange 6. and through which they pass, it is clear that the flange 11.
will contact with the flange 6. when the cushion 8. is compressed to its limit and
thereby act as a safety guard to prevent undue or excessive stress being brought to
bear on the rivets 12. to shear them, or to the cushion to destroy its elasticity.
I also provide the groove 11* formed on the outer peripheral edge of the flange 11.
for the purpose of forming an oil stop and drip and thereby arrest the flow of waste
oil from the joint 5ª when the wheel is at rest.
The holes of the flange t. of the tire 4. are preferably made larger than the
body of the rivets 12. to supply the requisite amount of clearance or play when the
cushion is compressed to its limit and to ensure contact between the surfaces of
the guard or safety flange 11. and the edge 10. of the flange 6. of the tire at the same
time avoiding any contact between the bodies of the securing rivets 12. and the
edges of their holes in said flange.6.
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 :-
Claim 1st. In a cushioned car-wheel, the combination with the centre and the
tire thereof, having an interposing elastic cushion, of an inwardly projecting flange
formed on the outer face of said tire and having its inner peripheral edge tapered
or flared outwardly, said flange adapted to contact with the outer face of said
centre, an annular and outwardly flaring flange projecting out and over the inner
peripheral edge of said flange of tire, and suitable securing rivets for securing said
tire to said centre, substantially as set forth.
Claim 2nd. In a cushioned car-wheel, the combination with the centre and the tire
thereof having an interposing elastic cushion, of an inwardly projecting flange
formed on said tire and contacting with the outer face of said centre, said flange
having its inner peripheral edge flaring slightly outwardly, as described, an annular
outwardly flaring flange or shield formed on the outer face of said centre and pro-
jecting over and beyond the outer face of said tire, said flange having an annular
groove, as described, formed on the peripheral edge thereof, all combined and
arranged substantially as and for the purpose set forth.
Claim 3rd. In a cushioned car-wheel the combination with the tire and the
centre thereof having an outwardly projecting peripheral thrust flange formed on
the inner face of said centre and au inwardly projecting flange formed on the outer
face of said tire, of an elastic cushion surrounding said centre and extending across
the face thereof and between said flanges, the outer shield surrounding said cushion
and the outwardly flaring flange formed on the outer face of said centre and adapted
to contact with the inner peripheral edge of said flange of tire, substantially as aud
for the purpose set forth.
