1, EDGAR PECKHAM, of the City of Syracuse, County of Onondaga and State of
New York, United States of America, Manufacturer, do hereby declare the nature of
my invention for IMPROVEMENTS IN CAR WHEELS, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:
This invention consists in a novel construction of a car wheel combining simplicity,
with durability and sufficient elasticity to obviate undue jarring of the wheel.
The invention is fully illustrated in the annexed Drawing, wherein Figs. 1 and 2
are respectively outer and inner side elevations of a car wheel embodying my
improvements, Fig. 3 is a transverse section of the same, Fig. 4 is a detached
transverse section of one-half of the web with its reinforcing rings, and Fig. 5 is a
detached face view of a portion of the sectional retaining ring by which the web is
locked on the tire.
Similar letters of reference indicate corresponding parts.
A-represents the car axle, B-the hub of the wheel,--the web and
-D-the tire. The said hub I prefer to form either of cast iron or cast steel and
with a circumferential flange-a-and a circumferential rabbet--at one side of
said flange. The web-(-I form of a single disk or plate of wrought steel and with
a central eye by which it is seated in the rabbet--of the hub.
By means of an annular collar-b-slipped onto the rabbetted portion of the hub,
and bolts-e-e-passing through the said collar-b-, web-C-and flange-a-,
the web is clamped between the collar and flange.
In order to brace the web--I dish the same around its central portion and
conform the adjacent sides of the flange-a-and collar--to the disk of the web as
shown in Fig. 3 of the drawing.
The outer peripheral portion of the web I reinforce by annular plates or rings,-d-
and, rivetted to opposite sides of the aforesaid portion of the web.
The tire D-may be secured to the described weh in any suitable and well known
manner and I wish it to be distinctly understood that I do not confine myself to any
particular means of securing the tire to the web.

page_text: The means illustrated in the annexed Drawing consist in providing the reinforcing
ring-d-with a circumferential flange--which enters into an undercut
flange, g on the inner circumference of the tire, and sectional retaining rings-h-
and placed over the reinforcing ring-e-and entering an undercut groove-i-
in the inner circumference of the tire, the outer retaining ring-h-being provided
with an outward flange which enters the undercut portion of the groove-i-as shown
in Fig. 3 of the drawing.
Bolts --pass through the
plates-d-e-h-and--and intervening
web-C, and are provided with nuts by which the said parts are securely clamped
together.
Having now particularly described and ascertained the nature of my said invention,
and in what manner the same is to be performed. I declare that what I claim is :-
1-A car wheel having a web composed of a single wrought metal disk reinforced at
its periphery by rings extending around the peripheral portion of said disk and
secured thereto, substantially as set forth and shown.
2-A car wheel composed of a hub, a single annular wrought metal disk forming
the web, reinforcing rings attached to the peripheral portion of said web, and a tire
secured to said web, substantially as specified.
3-In a car wheel, the combination of a single wrought metal plate dished around
the center and constituting the web of the wheel, and a hub having a flange and a
collar holding between them the central portion of the aforesaid plate, and having
their inner sides conformed to the dish of said plate to brace the same, substantially in
the manner specified and shown.
