Improvements connected with Locks for Cycles.
I, FREDERICK JAMES HOYT, of 53 Dearborn Street, City of Chicago, County
of Cook, and State of Illinois, United States of America, Inventor, 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 locks for cycles, and its object is to improve that class of
bicycles in which a locking device is employed to lock the wheels when the
apparatus is not in use, to prevent the same from being stolen or taken away by an
unauthorized person.
To this end my invention consists in a cycle provided with tubular arms, the
combination therewith of the pedal casing to which the lower converging ends of
the arms are connected, a pedal shaft having its bearings in said casing, a detachable
locking case located between and attached to the converging ends of the said arms
and adapted to brace said arms, said locking case provided with a bolt, and
said pedal casing and shaft each provided with an aperture to receive said
bolt, and a suitable key, as hereinafter more particularly described and claimed.
Thus I obtain great simplicity in construction and operation and, as will be seen,
also great efficiency.
My invention is illustrated in the accompanying drawings in which
Fig. 1 is a side elevation of a bicycle of a well known form showing the front of
the locking case applied thereto and showing pedal shaft in section ;
Fig. 2, a back view in detail of the locking case and bolting parts;
Fig. 3, a transverse section lengthwise of pedal shaft showing connection of
locking bolt therewith;
Fig. 4, a detail longitudinal section of pedal shaft and sleeve.
Referring to the drawings, a a a, b, c, are the tubular parts of a bicycle frame of
a well known form, and in which b, c, are the arms which carry or to which are
attached, a sleeve, d, which forms a bearing for a pedal shaft, e.
In the form of frame shown I secure to the arms, b, c, just above the sleeve, d,
a case, G, which carries a locking mechanism. I have shown a simple well known
form of lock and key, but any desired form of lock and key may be employed that
will force a bolt into a notch, slot or hole in the pedal shaft. The form of locking
mechanism shown attached to the case, consists of a bolt, H, notched at, i, i, and
provided with a back spring, k. P is the key. The pedal shaft, e, is provided
with a slot or mortise, f, into which enters the bolt H, when thrown by the key.
The bolt when unlocked is held in the case above the sleeve, d, and when thrown
it passes through the hole, s, in the sleeve and enters the aperture in the pedal
shaft. The locking case is provided with a suitable key hole and any form of key
corresponding to the character of lock, may be employed.
The location of the locking case as described renders the case a substantial
brace for strengthening the converging ends of the tubular arms.
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 :-
In a cycle provided with tubular arms, the combination therewith of the pedal
casing to which the lower converging ends of the arms are connected, a pedal shaft

attached to the converging ends of the said arms and adapted to brace said arms,
said locking case provided with a bolt, and said pedai casing and shaft each
provided with an aperture to receive said bolt, and a suitable key, substantially as
described.
