(Cl. 2841-1126)
This invention relates to new and useful im
provements in roller skates an-d more particularly
to skates of the type constructed and arranged to
permit the person skating thereon to describe
5 curves of substantially small radii.
The principal object of the present invention
is to provide a skate of the character set forth,
embodying certain improved structural features
and arrangements together with novel means for
absorbing shock imparted to the front wheel as
sembly or mounting by impact or collision with
15
distance and has its forward edge portion turned
up or flanged as indicated at I I to provide a flat 5
end surface portion I2 for engagement with the
surface over which the skate is travelling when
said skate is tilted onto the front wheel assembly
by the skater as illustrated in Figure 2 of the
drawing, thus guarding against or preventing the 10
fore part or tip of the supporting section I from
an object or obstruction for the purpose of pre
contacting or scraping against such skating
venting crystallization of the metal in the ele
surface.

The front wheel assembly comprises a spindle
supporting bracket I3 which includes upper and 15
lower webs or portions I4 and I5 arranged in
relatively spaced parallel relation with respect to

Another object of the invention is to provide
a skate of >the stated character constructed to
include a member yarranged. to engage the surface
being skated upon when the skate is tilted up
onto the front wheel assembly for the purpose of
2O preventing the forepart or tip of the foot support
from contacting such skating surface.

Other features and objects of the invention and
the details of construction thereof are set forth
hereinafter ~ and shown in the accompanying

means of rivets or the like I0. As shown, the

As shown in Figure 1 of the drawing, the rear

In the present instance, the inner end of the
upper iiange or web portion 33 of the bracket
29 is turned upwardly as indicated at 34 to a
position adjacent and parallel to the upturned
portion I9 of the lower web I5 of the spindle
bracket I3 and this upturned portion 34 of
bracket 29 is slotted or notched as at opposite
sides thereof adjacent said web portion 33 as in
dicated by reference numerals 35, the arrange
ment being such that the upper projecting por
tions 36 of said portion 34 above the notches 35
therein function to positively limit rotation of
the bracket 29 and spindle 24 by engaging the
adjacent face of the upturned portion I9 of the
25 spindle bracket I3 after said bracket 29 and spin
dle have pivoted or rotated a predetermined dis
tance in either direction.
As shown particularly in Figure 4 of the draw
ing, the annular portions 3l! of a pair of arms 38

looselyY embrace the spindle 24 intermediate the
supporting webs I4 and I5 of bracket I3 and
these arms 38 engage or project through the slots
or notches 2l, and 35 at opposite sides of the
upturned portions I9 and 34 of the brackets I3
35 »and 29 respectively.V An upstanding Vlug 39 is
provided at the outer edge of each of the arms
38 and the inner edges of said lugs 39 are under
Y cut or notched to receive the extremities of a
spring 40 which is coiled about the spindle 24
40 and functions to yieldingly maintain said spindle
24, bracket 29 and wheels 32 in axial alignment
yet permit the pivoting of these elements with
porting section I as shown in Figure 5 to absorb
shocks imparted to the front wheel assembly, the
pivotal suspension of said bracket I3 from the
bracket 6 effected through the pin I8 permitting
the bracket I3 and wheel assembly to pivot
slightly relative to said bracket 6 against the 15
yielding resistance afforded by the springs 4I.
Pivotal movement of the bracket I3 and wheel
assembly is quite restricted, however, as- clockwise
movement thereof with respect to the drawing
is positively limited by engagement of the for 20
ward `edge portion of the-upper web vI4 of >said
bracket with the underside of the flat Vportion 1
' of the bracket 6 while movement in the opposite
or counterclockwise direction is positively limited
by engagement of the upper vextremities of the 25
lugs 4I with the underside of the foot section I
but between these fixed limits pivotal movement
of the bracket I 3 and wheel assembly is permitted
against the yielding resilience of the springs 42
which tend to urge these members in the ñrst 30
mentioned or clockwise-direction and effectively
function to absorb, at least in part, any shock
or impact upon the >front wheel assembly of the
skate.

While a particular embodiment of the inven 35
tion has been set forth herein for descriptive
purposes, it is not intended that said invention
shall be precisely limited thereto but that modifi
cations and changesY may be incorporated and
embodied therein Within the scope of the annexed 40
claims.
I claim:
'
'
respect to brackets I3 and 6 in a direction and
' VVl. In a skate including a foot support, abrack
degree depending upon the location and amount
et secured to the lunderside of said foot support,
a spindle support pivoted to said Vbracket for lim 45
ited movement in a plane substantially perpen
dicular to the Vplane of the foot support, a spindle
rotatably mounted in said spindle support, a
wheel-axle rotatable with said spindle, mecha
nism tending to resist rotation of said wheel axle 50
45 of pressure applied to the foot supporting sec
tions I and 2 by the skater, the extent or degree
of such pivotal movement being positively limited
by the projecting portions 36 of the upturned
portion 34 of bracket 29 which engage the up
turned portion I9 of said bracket I3 as above de
scribed.
'
The upturned portion I9 of the bracket I3 ex
tends between the arms 38 and Yfunctions as a
centering means for the relative pivotable ele
55 ments of the front wheel assembly when in nor
mal position, and when these latter elements piv
otv in either direction, said upturned portion I9
maintains the opposite arm 33 in its normal posi
tion axially with respect to the skate while the
60 other arm 38 is actuated vby means of the up
turned portion'34 of the bracket 29 which ro
tates with> the spindle 24.V This rotation occurs
against the action of the spring 40 and by main
taining the other arm 38 in its normal position
65 the extent of compression of the spring 40 is
increased, thus building'up a greater force in
said spring 40 Vfor the purpose of returning the
pivoted elements of the wheel assembly to their
normal position axially of the skate.
For the purpose of absorbing shock imparted
to the wheel assembly and’preventing crystalliza
tion of the metal in the various component parts
thereof ' caused by impact or collision of the
wheels 32 Ywith relatively stationary or heavy ob
75 jects' or obstructions, a pair of lugs 4I are
