Improved Look for Cycles.
CHARLES SANGSTER, Cycle Engineer, 14 Whitevale Dennistoun, Glasgow,
do hereby declare the nature of this invention to be as follows:-
In carrying out this invention & referring to the drawing herewith, (which
shows its application to the steering column of a cycle for the particular purpose
of locking the steering wheel to prevent its turning in the frame). A, is the frame
loop, upon which are two lugs to receive the bolt B, which passes through them,
upon this bolt are 3 or more nibs or catches & upon the bolt B are mounted 3 or
more circular washers C, having keyways to receive the nibs or catches on bolt &
are also recessed at both ends to allow of free turning, when the recesses are on a level
with the nibs or catches on bolt B. The handle bar clip D has also a lug to receive
the bolt B. The circular washers C are figured or lettered, so that, when a pre-
arranged word or sign is formed, the slots or keyways will all come into line & the
bolt will then be free to be raised or lowered as required for locking or unlocking
the machine. If required I may also place a spiral spring between the lower lug
or frame loop A and the shoulder of bolt, so as to give a firmer action.

COMPLETE SPECIFICATION.
Improved Look for Cycles.
I, CHARLES SANGSTER, formerly of No. 14, Whitevale, Glasgow, in the County
of Renfrew, North Britain, but at present of No. 43, Raglan Street, Coventry, in
the County of Warwick, Engineer, 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 :-
This invention relates to an improved lock for cycles, and has for its object to
enable the steering post by means of a simple device to be readily locked against
rotation in order to prevent the unauthorised use of the machine.
For this purpose, I form upon the loop or bearing for the steering post, which is
carried by the backbone or frame, two lugs and upon the steering bar clip, or, it
might be upon the head or steering post, I form a third and corresponding lug, and
I bore these several lugs to receive a bolt or key hereinafter more fully referred to.
Within the lugs of the loop or bearing, I mount with capability of endway move-
ment, a bolt or key in such manner that in one position the upper end thereof
engages the hole in the lug of the steering bar clip, or steering post and thereby
locks the steering post with the frame.
Upon this bolt or key, I form several bits or projections, and I mount upon such
bolt between the lugs of the loop or hearing a corresponding number of apertured
cylinders or washers, each of which is formed with a key way or slot, correspond-
ing with the bits or projections of the key, and the ends of these cylinders or
washers are recessed to receive the bits or projections and permit the cylinders or
washers to be freely turned in either the raised or lowered position of the bolt
or key.
The washers or cylinders are, upon their exterior, milled to facilitate the turning
thereof, and they are correspondingly figured or lettered so that when the bolt or
key is raised until its upper end engages the aperture in. the lug of the steering
post, the cylinders or washers may be turned until the slots or key-ways are out of

page_text: turning thereof and they are correspondingly marked with circles of figures or
letters so that when the bolt or key c. is raised until its upper end engages the-
aperture 63 in the lug of the steering bar clip 61 as indicated at Figure 4. the
cylinders or washers d. may be turned round until their slots or key-ways d' are
out of alignment with the bits or projections ¹ of the bolt or key c. when the
steering post b. will be securely locked against rotation, a flat spring d³ interposed
between the washers or cylinders d. and the upper lug a' serving to prevent the
rattling or shaking thereof.
The figures or letters upon the cylinders or washers d. are arranged after the-
manner of a permutation lock so that when a pre-arranged word or sign is formed
thereby the three being in a given vertical line the key ways or slots d' are all in
alignment thus permitting the key or bolt c. to be raised or lowered and the steer-
ing post b. to be locked or unlocked, and in locking the steering post b. the cylinders
or washers d. are turned into various irregular positions, so that a person ignorant
of the pre-arranged word or sign would find it difficult or impossible to form the
required combination of figures or letters to unlock the device.
In order to hold the bolt or key c. firmly against accidental rotation, and to-
automatically withdraw the same from the aperture 63 of the lug 6 of the steering
bar clip upon the key-ways or slots d' of the washers or cylinders d. being turned
into alignment with the bits or projections c¹ thereof, the upper end of the bolt or
key c. is formed with a feather or projection c* which fits a corresponding key-.
way a* formed in one of the lugs a² of the loop or bearing a whilst the lower end
of the bolt or key c. is formed with an enlarged head and a coiled spring c³ is.
interposed between such head and the lower lug a' of the loop or bearing a¹ and
which automatically acts to draw the bolt or key c. downward in its unlocked
position as represented at Figure 3. and which is compressed by the action of
raising the bolt and locking the steering post as indicated at Figure 4.
Although I have herein before shown and described the locking bolt or key c. as.
carried by the loop or bearing a' of the frame a. and the aperture 63 to receive the
same as formed in the lug 6* of the steering bar clip 6, I would have it understood
that this arrangement of parts may if desired be reversed, that is to say, the lugs a
might be formed upon the steering bar clip 6' and the lug b' might be formed upon.
the loop or bearing a¹.
Or, the lug b' instead of being formed upon the steering bar clip 61 might be
formed upon the steering post b. and the device might in other respects be somewhat
modified without departing from the spirit of the invention.
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 :-
:-
1. In a lock for cycles, the combination of a sliding bolt or key provided with
several bits or projections thereon, several cylinders or washers mounted upon the
bolt or key, and slotted to correspond with the bits thereof, suitable bearings for
the bolt or key upon one part to be locked and an aperture or the like upon the
other part to be locked adapted to engage the bolt or key, substantially as herein,
shown and described.
2. In a lock for cycles, the combination of a sliding bolt or key provided with.
several bits or projections thereon, several numbered or lettered cylinders or washers.
mounted upon the bolt or key and slotted to correspond with the bits thereof and
formed with recessed ends, suitable bearings for the bolt or key upon one part to be-
locked, an aperture or the like upon the other part to be locked adapted to engage
the bolt or key, and a spring for steadying and automatically withdrawing the bolt.
or key, substantially as herein shown and described.
