ROLLER SKATE ATTACHMENT
Clarence A. VVhited, Jenkins, Ky.
Application April 2, 1945, Serial N0. 586,059
6 Claims. (Cl. 280-1137)
This invention relates to roller skates, the pri
mary object of the invention being to provide a
traction device attached to the skate in such a
way that the traction device may be swung to a
2
metal material in such a way as to provide ?anges
15 along its longitudinal edges, the ?anges l5
being inclined inwardly toward each other, to
position beyond the rollers of the skate, to permit Cr grip the traction pad 56, which may be in the
form of a leather or rubber block.
the person using the skate to walk over polished
loors, and up or down steps, without danger oi
slipping.
The ends of the main plate l4 are extended
upwardly at right angles, and provide ears H,
which are formed with openings to receive the
washers I8 and I9, which washers are mounted
on the axle 'i, at opposite ends thereof, the wash

Figure 6 is a vertical sectional view through a

Referring to the drawing in detail, the body
portion of the skate is indicated by the reference
naracter 5 and includes front and rear brackets
B which‘ support the axles ‘I on which the wheels
8 are mounted.
Forming a part of each bracket 6, is an axle
housing 9, the axle housings being of widths to
space the wheels 8 on their axles.
The rollers, forming a part of the skate, are
provided with tubular sections 1B formed with
annular flanges H at their ends, the ?anges ll
acting to hold the roller sections l2 in place, the
sections l2 being provided with the usual ball
bearings l3.
The traction device, forming the subject matter
of the present invention, comprises a holder em
bodying a metal plate constructed to provide a
main plate l4 stamped out of a length of sheet
move it to its active or inactive position.
A laterally extended ?nger piece 25 is formed
on the pivoted latch arm 23, and affords means
whereby the latch arm may be moved from its
position within a notch of the washer Hi to re~
lease the traction pad housing for pivotal move—
ment.
From the foregoing it will be seen that due to
the construction shown and described, the trac
tion pad housings may be moved to their active
positions as shown by Fig. 1 of the drawing,
where they extend beyond the rollers of the skate
so that the person using the skate may walk on
polished floors, or steps, without danger of slip
ping.
When it is desired to use the skate in skating,
the traction pad housings may be swung to the
positions shown by Fig. 3 of the drawing where
they are out of the way, allowing free use of the
rollers.
What is claimed is:
