IMPROVEMENTS ON CAR WHEELS
Year: 1881

page_text: LETTERS PATENT to Enoch Lewis Taylor, of Philadelphia, in the County of
Philadelphia, and State of Pennsylvania, United States of North America, for
an Invention of "IMPROVEMENTS ON CAR WHEELS."
COMPLETE SPECIFICATION filed by the said Enoch Lewis Taylor at the
Office of the Commissioners of Patents on the 9th May 1881.
ENOCH LEWIS TAYLOR, of the City of Philadelphia, in the County of
Philadelphia, in the State of Pennsylvania, United States of North America,
Civil Engineer. IMPROVEMENTS ON CAR WHEELS."
"
This Invention has relation to certain improvements designed to reduce the
rigidity of the trucks, to remove the strain on the axle, to reduce the grinding in
traversing curves, to reduce the liability to jump the track, and to provide a face
or tread of more or less flexibility to receive and soften accidental shocks, and
which may have a very low degree of sound bearing properties.
In the accompanying Drawings Figure 1 is a vertical section of my improved
car wheel of the web pattern. This wheel consists of the body portion filling and
front wall plate. The body portion is formed with a hub A, rear wall A³, and
tread flange A forming the solid portion of the wheel. This portion is recessed
laterally to receive the tilling C, and the front wall plate B is fitted into the recess
around the hub on the filling, and is secured to the solid or body portion A by
means of the bolts D.
In Figure 2 a wheel is illustrated of somewhat similar character except that it
consists of an outer part and an inner or hub portion, eacli part having like
characteristics of the flange and thread, the tread of the interior part constituting
the hub E, turning in and fitted into the exterior or outer part F, as shown in the
Drawing, the parts E and F having on their inner edges similar flanges a, b, for
like purposes. The flange a on the inner part E is designed to be fitted into a
recess or seat c in the margin of the outer part, said recess being about equal in
depth to one half the flange let into it.
This construction is designed to keep the respective parts in position and to
provide against or prevent spragging the wheels on a curve or when any sudden
lateral strain occurs; to prevent accidental displacement of the outer part I
employ on the front a ring plate G, which is bolted to the hub portion E and
overlaps the outer portion into which its is recessed as indicated at e. When the
wheel is designed for especial service to run silently and without jarring on surface
or elevated roads I prefer to employ a non resonant substances of vulcanized rubber,
compressed fibre, or other suitable material to produce the effect either as a tread
or as a filling, or in both capacities in the same wheel.

page_text: This is
As illustrated in Figure 2 the outer portion of the wheel is boxed or recessed at
m to receive the detachable and removable tread K of this character.
designed to be secured in place by bolts D passing through the body portion and
annular wall plate or front ring H. It is apparent that this tread can be easily
and quickly replaced when necessary.
In Figure 3 is illustrated a modified construction of this wheel, in which a hollow
central portion or web hub A is employed, this inner portion or hub being recessed
to receive a filling I of wood, paper, or. other suitable material for the purpose of
deadening the sound and allowing some elasticity.
Figure 4 is a section of part of the wheel on line 1-2 of Figure 1 to more
clearly show the oil box g, which is cored out on the inner bearing surface of the
outer portion, or it may be cored in the outer bearing surface of the inner
portion of the wheel. In this oil recess is located a curved tube h, which is
arranged at one end in connection with the discharge perforation k, and is bent
outwards at its outer end, so that it takes up oil only at one point in the revolution
of the wheel, thus constituting a motion feeding oil box without waste when the
wheel is not in motion, and discharging into the joint between the sections at but
one point in the revolution of the wheel, so that it needs replenishing only at long
intervals.
Instead of applying the brake to the tread of the wheel in the ordinary way, I
prefer to arrange it to engage a secondary or additional flange or flanges L, L',
Figs. 2 and 3, one of which is formed on the hub of the wheel, as illustrated in
the Drawings. In this manner it is designed to employ a much shorter brake
bar, and by using four rubbers or shoes to increase the pressure upon the wheels.
Having thus fully set forth my Invention what I claim as new, and desire to
secure by Letters Patent is,―
First. A car wheel in the web pattern, in which the hub, the back, and the
flange or tread are made in one piece in combination with a face plate and an
elastic filling, as set forth.
Second. A car wheel in which the outer annular and flanged portion is combined
with and arranged to turn on a central portion having a flange on the same side of
the wheel as the flange of the annular portion of the same, substantially as set
forth.
Third. A car wheel in which an annular portion and its tread of vulcanized
rubber, compressed fibre, or other equivalent is combined with a central portion on
which the annular portion can turn, substantially as described...
Fourth. The combination of the recessed annular portion of the wheel with the
tread, the face plate and the fastening bolts having nuts sunk into the recessed
annular portion of the, wheel, as specified..
Fifth. A car wheel having one or more annular brake flanges, as shown at L, to
be acted on by a short, single, or double brake bar carrying two or four brake
shoes, as set fourth.
Sixth. A car wheel in which a hollow webbed hub, between the walls of which
is fitted a filling of wood, paper, fibre, or other suitable material, as set forth.
Seventh. An oil box so situated and constructed as to need resupply only at
long intervals, and discharging only when the wheel is in motion or in making
_ revolutions, and but at one point in revolving, as set forth.
In witness. whereof, I, the said Enoch Lewis Taylor, have hereunto set my
hand and seal, this Ninth day of May in the year of our Lord One thousand
eight.hundred and eighty one.
