of high speed.
Another object is to provide a skate for the pur

tilting of the foot supporting parts proper.
Other objects are to provide a skate constructed
for the attainment of the objectives above set
forth which is light in weight, strong and durable,
25 and inexpensive to manufacture.
Other and subordinate objects together with the
precise nature of my improvements will be clearly
understood when the following description and
claim are read with reference to the accompany
ing drawings.

the wheels and axles removed.

I0 for receiving the heel is ñxedly secured to the
heel platev 3 in advance of the rear wheel and by
means of the circular socket member 5. The
socket member 5 is provided with a radial concave
portion II forming an under rib on the socket 20
member fitting into the web 6 of the heel plate 3
and secured thereto by a bolt I2 the head of
which is countersunk in said concave portion Il
said bolt being provided with a nut I3.on the
under side of the web 6. The socket member 5 ’is 25
formed with upstanding marginal lugs I4 to
which the heel guard is riveted as at l5. 'I'he
heel guard I0 has secured thereto the usual ankle
strap I6 and buckle I'I.
The toe plate 2 which is of the usual edge con- 30
tour is formed with a center longitudinally ex
tending concave portion I8 forming an under rib
on said plate extending from midway of the plate
to the rear end thereof and ñtting into the web
'6 of the heel plate 3. The toe and heel plates 35
2 and 3 are adjustably connected together by
means of a horizontally extending slot I9 in the
heel plate 3 and a nut and bolt 20 and 2| as
shown in Figure 4.
The front axle 22 is mounted on the toe plate 2 40
by means of a bolster 23 pivoted as at 24 between
a pair of front and rear lugs 25 and 26, of dif
ferent lengths, to rock about an axis inclined
lengthwise of the skate so that tilting of the foot
support I sideways in opposite directions will 45
cause the axle 22 to swing in opposite directions,
respectively. The usual compression member 21,
in the form of a block of rubber, is interposed
between the bolster 23 and the toe plate 2 for 0
holding the foot support I level and the axle in
normal position. The lugs 25 and 26 are struck
downwardly from the tbe plate 2 in front of the
portion I8 to locate the front axle 22 directly
under the ball of the foot so that steering may 55
be readily effected by pressure applied principally
said washer seating against a shoulder 49 on the
by the front part of the foot.
The toe plate is provided with the usual toe
clamps 28 located in front of the front axle 22.
The front axle 22 is underslung and extends
well beyond the sides of the toe plate 2 so that
axle 22. The outer end of the outer race member
large front wheels 29 may be used, a low center
of gravity obtained at the front of the skate and
the front wheels spaced well beyond the sides of
the toe plate. As will be apparent these features
all provide for stability at the front of the skate,
easy riding and quick acceleration to high speed.
The foot support i is supported at its back by a
single rear wheel Sil running between the arms 8
and whereby the support i may be easily tilted
for steering purposes, weight reduced at the rear
of the skate, and side sway incident to tilting of
the foot support reduced to a minimum.
The front wheels, one of which is shown in
20 Figures 1l and 12 are rubber tired and comprise
a pair of opposite metal web plates 3| outwardly
flared at their outer edges to provide opposed co
operating rim portions 32 spaced apart at their
inner edges, and a pair of opposed annular socket
25 members 33 forming therebetween a transversely
round socket 34 extending around the inner edges
of the rim portion 32. The tire 35 comprises a
transversely round outer tread portion 36 seat
ing against the rim portions 32 and a smaller
similarly shaped inner bead portion 3l formed
integrally with the portion 36 and seating in the
socket 34. Bolts 38 secure the plates 33 together
and clamp the tire 36 in the described position.
The web portions 3l are formed with outer and
inner hub portions, respectively, 39 and ¿il? co
operating to form therebetween a chamber lll,
the outer hub portion being provided with an ex
ternal edge bead 42 and an internal edge flange 43,
and the inner hub portion having a radial edge
40 ñange ¿lli surrounding the axle 22. Within the
chamber ill is an anti-friction roller bearing com
prising outer and inner sleeve-like race members
45 and A16, respectively, and roller bearings 41. A
wear washer @13 is interposed between the flange
45, 48 and the inner end of the anti-friction bearing
G5 bears against the shoulders 43 whereby said
race member is held against longitudinal play. A
washer 5D is mounted on the front end of the
axle 22 against the outer end of the inner race
member 46 and within the edges of the flange (i3.
A cotter pin 5I in the axle 22 bearing against the
washer 50 secures the hub portions 39 and 40 and
the parts of the anti-friction bearing in position 10
on the axle 22. The usual dust cap 52 fitting over
the bead 42 closes the outer end of the chamber 4 l.
The foregoing is a detailed description of a
preferred embodiment of my invention and it is
thought that its construction and operation will
be clear therefrom. It is to be understood how
ever that the present disclosure is illustrative
rather than restrictive and that right is herein
reserved to modifications of details disclosed
falling within the scope of the appended claim. 20
What I claim is:
In a skate structure, a frame comprising in
terñtting heel and toe portions, said toe portion
fashioned with a longitudinally extending arcu
ate-shaped web terminating at the sides thereof 25
in oppositely disposed ñanges, said heel portion
fashioned with a longitudinally extending arcu
ate-shaped web receiving said ñrst mentioned
web therein and terminating at the sides there
of in depending ñanges extending in antiparal 30
lelism with said first mentioned flanges, the join
tures of the flanges to one web sea-ted within the
joìntures of the flanges to the other web whereby
to maintain said webs in seated condition against
relative creeping movement when connected to 35
gether, said depending flanges extending longi
tudinally of said frame and terminating beyond
one end of the web thereof in spaced arms adapt
ed to secure a roller therebetween and coacting
with said webs to reenforce said frame interme 40
diate of the ends thereof, and means connect
ing said webs together whereby said portions are
adjustable lengthwise relative to each other.
