Improvements in or relating to Vehicle Wheel Rims of Wood.
I, JAMES CHARLES HOSKINS VAUGHT, of Philipsburg, in the County of Granite
and State of Montana, United States of America, Millman, do hereby declare
the nature of this invention to be as follows: -
The purpose of the present invention is the provision of a joint in the con-
struction of vehicle wheel rims of wood which will obviate Hattening of the
wheel at the joint between the rim sections, prevent the splintering or breaking
off of corner portions of the wooden sections and which will secure an equal
distribution of the strain and result in the formation of a rim of about equal
strength and capability of resisting strain at all points throughout its length.
The wooden rim sections of the vehicle or wagon wheel are jointed on obliquo
lines by beveling the contiguous ends of adjacent sections so as to secure a
maximum amount of strength and obviate the cracking or breaking off of inner
corner portions of one of the rim section ends. The number of sections entering
into the formation of a rim is immaterial so far as the spirit of the invention is
concerned, because the improvement resides, as heretofore stated, in the parti-
cular manner of forming the joint. One of the rim sections has its end
beveled outwardly from the inner side and the other section has its matching
end correspondingly beveled inwardly from the outer side, whereby when the
two sections are fitted together they will meet and form an oblique joint. This
formation of the joint prevents the corners of the sections from chipping or
breaking off.
The section having the outwardly beveled end is formed with an opening
adjacent to the joint for the reception of the tenon of a spoke, the shouldered
end of the spoke engaging with the inner side of the section and holding it
from inward movement when said section is lowermost and sustaining the weight
of the load. The inward bevel of the adjacent section abutting against the out-
ward bevel of the section is supported thereby. The two sections are held in
alinement by means of a dowel pin passing obliquely through registering open-
ings formed in the matching beveled ends thereof. This dowel pin also enters
the spoke tenon thereby securing it and the sections in firm relation and resulting
in the formation of a substantial joint.
A plate overlaps the joint and is fitted against the inner side of the rim
sections and is bolted to the end portions bordering upon the joint in the usual
manner. This plate has its edge portions flanged to embrace the side portions
of the rim sections near their inner periphery, thereby supplementing the action
of the dowel pin in preventing lateral displacement of said sections. This
plate has an opening near one end, through which the tenon of the spoke adjacent
to the joint passes. This plate is essential in the construction of light wheels
for buggies, sulkies, and carriages, but in the manufacture of heavy wheels for.
wagons and drays the plate may be dispensed with, the matching of the beveled
ends of the rim sections and the overlapping tire being sufficient to hold the
sections in proper position.

page_text: The shoulder at the base of the spoke tenon engages with the inner side of
the said plate adjacent to the opening therein, but in some instances it may be
desirable to have the shoulder bear directly against the inner side of the rim.
This may be effected by having the opening in the plate sufficiently large for
the shouldered end of the spoke to pass therethrough. In order to prevent the
opening in the plate from weakening it to such an extent as to destroy its effec-
tiveness, said plate is formed with a flange surrounding the opening and encir-
cling the spoke adjacent to its shoulder. This flange also embraces the joint
between the spoke and rim.

Improvements in or relating to Vehicle Wheel Rims of Wood.
I, JAMES CHARLES HOSKINS VAUGHT, of Philipsburg, County of Granite and
State of Montana, United States of America, Millman, 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:-
The purpose of the present invention is the provision of a joint in the con-
struction of vehicle-wheel rims which will obviate flattening at the joint between
rim-sections, prevent the splintering or breaking off of corner portions of the
sections, and which will secure an equal distribution of the strain and result
in the formation of a rim of about equal strength and capability of resisting
strain at all points throughout its length.
For a full understanding of the merits and advantages of the invention refer-
ence is to be had to the accompanying drawings and the following description.
In the drawings,
Figure 1 is an elevation of a portion of a vehicle-wheel having its rim sections
jointed in accordance with this invention.
Figure 2 is a view similar to Figure 1, showing the joint in section.
Figure 3 is a detail view in perspective of the plate overlapping the joint
and secured at its ends to the subjacent end portions of contiguous rim-sections.
Corresponding and like parts are referred to in the following description and
indicated in the views of the drawings by the same reference characters.
The rim-sections of the vehicle or wagon wheel are jointed on oblique lines
by bevelling the contiguous ends of adjacent sections, so as to secure a maximum
amount of strength and obviate the cracking or breaking off of inner corner
portions of one of the rim-section ends. The number of sections entering into
the formation of a rim is immaterial so far as the spirit of the invention is
concerned, because the improvement resides, as heretofore stated, in the par-
ticular manner of forming the joint. One of the rim-sections, as 1, has its end
bevelled outwardly from the inner side, and the other section, 2, has its matching
end bevelled inwardly from the outside, corresponding with the bevel of the
section 1, whereby when the two sections are fitted together they will meet and
form an oblique joint 3. This formation of the joint prevents the corners of
the sections from clipping or breaking off.
The section 1, having the outwardly-bevelled end, is formed with an opening 4
adjacent to the joint 3 for the reception of the tenon 5 of a spoke 6, the shouldered
end of the spoke engaging with the inner side of the section and holding it
from inward movement when said section is lowermost and sustains the weight

page_text: of the load. The inward bevel of the section 2, abutting against the outward
bevel of the section 1, is supported thereby. The two sections are held in
alignment by means of a dowel-pin 7, passing obliquely through registering open-
ings formed in the matching beveled ends of the adjacent rim-sections. This
dowel-pin also enters the spoke-tenon 5, thereby securing it and the sections
in firm relation and resulting in the formation of a substantial joint.
A plate 8 overlaps the joint 3 and is fitted against the inner side of the rim-
sections and is bolted to the end portions bordering upon the joint in the usual
manner. This plate has its edge portions flanged as shown at 9, to embrace the
side portions of the rim-sections near their inner periphery, thereby supple-
menting the action of the dowel-pin in preventing lateral displacement of said
sections. This plate has an opening 10 near one end, through which the tenon 5.
of the spoke adjacent to the joint 3 passes. This plate is essential in the con-
struction of light wheels for buggies, sulkies, and carriages; but in the manu-
facture of heavy wheels for wagons and drays the plate 8 may be dispensed
with the matching of the bevelled ends of the rim-sections and the overlapping
tire being sufficient to hold the sections in proper position.
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. In the construction of wagon and vehicle wheels, rim-sections having their
matching ends obliquely jointed, the rim-section having the end outwardly
bevelled being formed with an opening adjacent to the joint for the reception
of the tenon of a spoke, and a dowel-pin extending across the oblique joint and
fitted into registering openings formed in the matching ends of the adjacent
rim-sections, substantially as set forth.
2. In a vehicle or wagon wheel, rim-sections obliquely jointed, the section
having its end outwardly bevelled being provided with an opening adjacent to
the joint, a spoke having its tenoned end fitted into the said opening, and a
dowel-pin extending across the oblique joint and passing through the matching
ends of adjacent rim-sections and entering the tenoned end of the aforesaid
spoke, substantially as set forth.
3. In a vehicle-wheel the combination of rim sections jointed on an oblique
line, the section having the outwardly-bevelled end being provided with an
opening contiguous to the oblique joint, a spoke having its tenoned end fitted
into the said opening, a dowel-pin extending across the oblique joint and entering
the tenoned end of the spoke, a plate overlapping the joint and having its side
portions flanged and embracing the sides of the rim-sections, and provided near
one end with an opening for the reception of the tenon of the aforedescribed
spoke, and means for securing the ends of the plate to the rim-sections bordering
upon the said oblique joint, substantially as set forth.
