PROVISIONAL SPECIFICATION.
Improvements in Cycle Treads.
I, WILHELM RACHLER, of VIII, Albertgasse, No. 23, Vienna, Austria,
Saddler, do hereby declare the nature of this invention to be as follows:-
My invention relates to improvements in cycle treads, and its object is to prevent
the wear and tear consequent upon the use of wood as a material for cycle treads,
and also the loss of power consequent upon the use of an elastic material such as
india rubber.
In carrying my invention into effect I build up the tread by superposing layers
of leather one upon another. Any suitable means for holding them together may
be made use of.
A wood core may be inserted in the centre of the tread..

Improvements in Cycle Treads.
I, WILHELM RACHLER of VIII Albertgasse No. 23 Vienna Austria Saddler,
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
statement :-
My invention relates to improvements in velocipedes and refers to the coverings,
casings or treads which are usually fixed over the pedals of such machines.
Heretofore the pedals were generally covered with india-rubber, which besides
being expensive had the particular defect due to its resiliency that much of the
power exerted in working the pedals was lost.
Now my invention has for its object to remedy such defects by providing a
cheaper casing or covering made of leather and preferably of bend leather which is
very durable and soft to the tread without being as resilient as india-rubber.
In the accompanying drawings
Figs. 1 and 2 are respectively a front view and a longitudinal section of my
improved leather covering.
Fig. 3 is an end view corresponding to Fig. 1.
Fig. 4 is another similar end view.
Figs. 5 and 6 show respectively in front and in end view a modification of my
invention. As clearly shown in the drawings my improved pedal casing or covering
consists of two leather strips or picces aa which are either placed one above the
other or one by the side of the other, that is to say that when more than two are
used they are arranged either in superimposed or in adjacent rows. These pieces or
strips are secured together by means of glue, pegs, nails such as bb, or they may be
rivetted, sewn, or connected together in any other suitable manner.
The casing or cylinder formed by means of these strips or pieces preferably of
bend leather is hollow in the centre as shown at d to allow of the insertion there-
through of the axes of the pedals.
These strips or pieces may be fixed upon a hollow wooden core such as c (Fig. 4)
through which the above mentioned axes would pass.

page_text: Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. For the pedals of velocipedes, the arrangement of a leather covering or casing
forming the tread of the pedal and consisting of a number of leather pieces or strips
placed in superimposed or adjacent rows and connected together by glue, nails,
rivets, stitches or the like, such covering or casing being hollow in the centre to
allow for the insertion therethrough of the axis of the pedal, substantially as
described and shewn and for the purpose set forth.
2. In coverings or casings of the kind above claimed the fixing of the leather or
pieces upon a hollow wooden case substantially as described and shown and for the
purpose set forth.
