11 Claims. (Cl. ZBO-11.26)
In the drawings,
My invention relates to roller skates and it has
vfor its object the provision of a new and improved
form and arrangement of parts by which a maxi
mum of strength is provided by the use of a mini
s mum amount of metal and whereby the manu
facture, plating and assembly- of the parts may
be eiïected with the least trouble and expense.
Itis one of the objects of my invention to pro
vide an improved resilient mounting for the axle
l0 by which. the supporting wheels of the skate are
connected with the framework,` and to provide
an improved arrangement of connecting means
between the frame and the outside sleeve forminga part of such resilient mounting. It is another
15 object of my invention to provide an improved
arrangement of extension bar and associated
parts by which the toe plate and the heel plate

It is another object of my invention to pro
vide an improved arrangement of bracket means
by which a downwardly open channel is formed,
the sheet metal forming the top wall of the chan
nel being curved l'downwardly so as to close one
end of the channel and serving thus to give the
channel a high degree of strength with respect to
transverse pressure thereon. Another object is
40 to provide a channel as above specified with the
wall portions in angular relationship to each

upper portions of the brackets merging at their~
lower ends into the walls of the channel.

prove devices of this type in 'sundry details here

which I have accomplished my several objects
are illustrated in the accompanyinß drawings and
are hereinafter speciiically described.- That which

tion and being provided with downwardly extend
ing ñanges I1 along its side edges. as is clearly
shown in Fig. 2. The heel plate Il is connected
with supporting wheels Il of any approved type 35
carried by an axle bolt Il bymeans of suitableconnecting parts as hereinafter described cooper
ating with brackets 20 and-2 I, as is clearly shown
in F18. 2.
'
The bracket 2l is shown. in Fig. 8, the other 40
bracket 2l being similar except that they are re
versely formed for use at opposite sides. As
shown in Fig. 8, the bracket 2l comprises a verti
cally disposed plate portion 22 having a trans
versely disposed ilange portion 2l` at itsupper 45
edge. The two brackets 24 and 2l are secured to
the bottom face of the transverse frame or heel
plate i8. being securely welded at several placesto the plate Il and also to each other at points
along the vertical plate or web portions 22v which 50
stand in face to face engagement with each other.
At a distance below the ilanges 23, each of the
brackets lis oifset outwardly so as to provide a

ribs 25 being pressed in the vertical plate or web
portions 22 from the upper edges of such vertical
I plate portions and extending downwardly at- an
angle so as to merge into the top wall portions
25 as is clearly shown in Fig. 8. At their for
ward ends, the brackets are provided with over
io
lapping lugs 21 and 28, see Fig. 9. which are ef
fectively connected together as hereinafter de
scribed for reinforcing the structure. At their
lower edges, each of the brackets 2l and 2|` is pro
vided with a downwardly extending arm 23 which
is provided with a collar 30 formed integrally
therewith, the two collars 30 of the two brackets
15
being opposltely disposed in axially aligned posi
tion with respect to each other. Each of. the
brackets is provided at its lower edge with an in
wardly extending ñange 3l which is continued
downwardly along the front face of the arm 28 to
20 a point adjacent the collar 38.
At the forward end o'f the skate, a toe plate 32
is provided having downwardly extending ñanges
33 along its side portions and a downwardly ex
tending flange 34 across the front end. The
transverse frame or toe plate 32 is supported by
wheels 35 of any suitable type mounted upon an
axle bolt 35 connected with the toe plate 32 by
means
as
hereinafter described
comprising
' brackets 31 and 38 as is best shown in Fig. 3.
30
The brackets 31 and 38 are arranged in general
similarity to the brackets 2li and 2|, the two
brackets 31 and 38 being similar to each other
except for reversed arrangement for enabling
them to be used at opposite sides in cooperation
36 with each other. As is best shown in Fig. 7, each
of the brackets 31 and 3l comprises a vertically
cured ilrmly in position therein by means of spot
welding or in any other suitable manner. The
sleeve 41 is preferably rolled out of ñat stock and
is provided at .one end with an inwardly turned
flange 48, as is clearly shown in Fig. 6, the oppo
site end of the sleeve 41 initially being left open
in cylindrical form as shown in Fig. 6. In the
formation of the skate, the transverse frame or
heel plate I5, the brackets 2li and 2| and the
sleeve 41 are ilrst ñrmly secured together by spot-I
welding with the sleeve 41 in the condition shown
in Fig. 6. .The transverse frame or toe plate 32,
the’brackets 31 and 38, and a sleeve 41 such
as that shown in Fig. 6 are likewise ñrmly secured
together preferably by spot-welding with such
sleeve 41 in position within the collars 44. The
parts are then in condition for plating which is
preferably effected at this stage of the assembly.
After"th'e two units comprising the end por 20
tions of the framework are plated, each of the
sleeves 41 is provided with an assembly such as
that shown in Fig. 5 comprising a rubber sleeve
48 having an axle member 50 mounted therein
also in the form of a Vsleeve having its middle por
tion expanded into the form of a ball as indi
cated at 5|.'the conformation of the rubber of
the sleeve 48 being such that the rubber when
held against radial expansion serves enectively
for preventing the withdrawal of the axle member
5t. The end portions of the sleeve 48 however
are flared so as to enable the axle member 5l
to have free swinging movement with respect
to the sleeve 41 about the ball 5i as a fulcrum.
'I'he axle member 58 is preferably formed out of
dat stock and is of a size to receive snugly the
disposed plate portion 3l provided at its upper axle bolts Il for mounting the wheels I8 in posi
edge with a transversely disposed flange 4I, the tion thereon. After the .sleeves 58 and 48 have
two brackets 31 and 38 being secured to the toe vbeen inserted into position within the sleeves 41,

45 Below the vertical plate portions 38, the two
For connecting the end portions of the frame 45
brackets are offset outwardly so as to provide a
work of the skate, I have provided an exten
sion bar 53 in the form of a downwardly open
of the channel at each side being disposed sub
channel, the channel bar 53 being of a size and
stantially parallel with the flange 4l and beingI shape to ñt snugly within the downwardly open

55 As is best shown in Fig. 7, the top plate portion As is clearly shown in Fig. 9, the lower edges of'
4| of each of the brackets is curved downwardly the side portions of the channel bar 53 abut 55
at the forward end of the bracket so as to close against the flanges 3i of the‘channel 24. In likethe front-end of the channel transversely serving manner the side portions of the bar 53 abut
thus to strengthen the channel formation greatly against inwardly extending ñanges 31a formed on
60 with respect to transverse pressure thereon, the the lower edges of the brackets 31 and 38. The
curved shoulder portion by which the closure of relation is such, by reason of the snug ilt of the
the channel is effected being formed in a down
extension bar 53 within the channels of the
wardly extending arm 43. At its lower end, the framework, that the extension bar reinforces the
