COMPLETE SPECIFICATION.
Improvements in Skates.
I, SAMUEL LOUIS SCHWARTZ, residing at 675 8th Avenue, of New York, in
the County and State of New York, United States of America, Merchant, 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
Specification:
This invention relates to roller skates, and the object thereof is to provide an
improved device of this class constructed as described in the following Specifica--
tion, in which a series of rollers are supported in a longitudinal bottom piece and
free to move therein.
The invention is fully disclosed in the following Specification of which the
accompanying drawing forms a part, in which,
Fig. 1 is a side elevation of my improved skate;
Fig. 2 a section thereof on the line a, .
In the practice of my invention, I employ a body piece A, of substantially the
same general form as the runner of an ordinary club skate, to the upper part of
which are secured the usual foot plates and screw operated clamps and other
devices for securing the skate to the foot.
The lower part or side of the body piece A is provided with a flat bottom B,.
formed by outwardly directed flanges on each side thereof, and secured thereto at
each end, by means of angle irons, or similar devices C, is a plate D, of the same
width and form as the bottom B, said bottom and plate being connected by screws
or bolts E, as will be readily understood.
Between the bottom B, of the body A, and the plate D, is a longitudinal slot F,.
which extends the full length of the skate, aud mounted rigidly therein are a
number of shafts G which extend through said slot and have mounted on each end
a roller H, as clearly shown in Fig. 2.
The length of the shafts G, between the rollers H, is slightly greater than the
width of the bottom B, of the body piece A, and the plate D, in order to permit
of the free movement of the rollers which are revolvably mounted upon their
shafts and the bottom or support for the rollers is preferably slightly convex, or
downwardly curved.
As thus mounted the roller shafts are rigidly secured within the slot F and the
rollers extend below the bottom plate so as to clear it and provide sufficient space
between it and the surface on which the skate, is operated. I may however, in
place of the slot F, employ an integral bottom piece having holes formed therein
adapted to receive the shafts which would be free to revolve, but could not move
longitudinally.
I provide a series of rollers arranged in pairs on shafts extending entirely along.
the bottom of the skate, the arrangement being such that one or more of said pairs.
of rollers are always in contact with the surface on which the skate is moving and
generally several pairs thereof.
With a skate thus constructed greater speed and also greater ease of movement.
may be attained and the parts are not so liable to get out of order and need
repairs as is usual in this class of devices.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
A roller skate having a longitudinal and continuous bottom in which is.

page_text: mounted a number of pairs of rollers, on shafts, which extend there-through and
which are free to revolve therein, substantially as shown and described.
2. A roller skate having a longitudinal and continuous bottom in which is a
longitudinal slot, through which pass a number of shafts each of which has
mounted thereon, at each end a roller, the arrangement being such that the shafts
are free to move in said slot, substantially as shown and described.
3. A roller skate having a longitudinal and continuous bottom piece, flat on its
lower side, a plate of substantially the same form secured thereto in such manner
as to leave a longitudinal slot between the bottom piece and plate, and a number
of shafts loosely mounted in said slot, each of which has a roller on each end
thereof the shafts being free to revolve and move longitudinally in the slot,
substantially as shown and described.
