Improvements in Locks for Bicycles and other Velocipedes.
I EDWIN KEMP HANLEY, of Elmira Chemung County State of New York, United
States of America, Railroad Dining Room Manager, 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 an improved lock for bicycles, tricycles, tandem and all
that class of wheels and has for its object to provide a means whereby the wheels may
he quickly and conveniently locked and wherein the lock will be at all times attached
to the bicycle in position for use in such manner as to constitute an ornament and
wherein only a small key need be carried by the rider.
The invention consists in the construction and combination of the several parts and
in the combination of the lock with a bicycle or vehicle of that class as will be herein-
after fully set forth and pointed out in the claims.
Reference is to be had to the accompanying drawings forming a part of this
specification in which similar letters of reference indicate corresponding parts in all
the figures.
Fig. 1 is a side elevation of a bicycle illustrating the application of the lock and
Fig. 2 is a plan view of the brake and guide levers and the attached lock.
Fig. 3 is a plan view of the lock with the cap-plate removed and a transverse section
through the head and
Fig. 4 is a front elevation of the lock and a partial elevation of the brake lever.
In carrying out the invention the lock is constructed with a suitable casing A. of
greater width at the rear end than at the front end a¹ the rear end being.made
preferably more or less rounding and the front end more or less concave.
Centrally and longitudinally within the casing a bolt B is held to slide between
guide posts and the sides of the casing at the front end, in which end an opening b
is provided to permit the egress of the bolt. "The forward end.faceb² of the bolt is
concaved to correspond with the concavity of the casing and to conform to the contour
of the bicycle head C. In one longitudinal edge of the 'bolt near the rear end, a
substantially V-shaped recess is produced and near said recess in front of the same
a key post d is vertically secured in the casing whereby when the key is inserted over
the post one tumbler of the bit will enter the recess and by engagement with. the walls
manipulate the bolt as illustrated in dotted lines Fig. 3°
A pin D is vertically secured centrally of the casing and to the rear of the bolt
projecting above the same upon which pin a plate E is pivoted at one end, the body
and other end of the plate being adapted to rest upon the upper surface of the bolt.
About centrally the plate E which for convenience we designate a "locking
plate" an aperture.e is produced essentially rectangular in form and from the opposing
side walls of the said aperture aligning horizontal studs eland e³ are projected. At the
rear end of the locking-plate, upon that side removed from the key-post one end of a
spring E¹ is secured, the other and free end of which spring is made to bear against
the guide post bupon that side of the locking plate. The locking plate is of a
sufficient width to normally partially cover the bolt recess. Near the rear end of the
bolt upon the upper face, a boss F is produced extending upward into the aperture
of the locking plate. Longitudinally in the bolt, a slot is made and smaller
aligning slots are also produced in the top and bottom sides of the casing.
In the operation of the lock when the key which is provided with two tumblers,
the lower one being the longer is inserted over the post, the upper tumbler will move
the locking plate to one side before the lower tumbler acts bringing the boss on
the bolt in alignment with the space between the studs and as the lower tumbler
carries the bolt forward when the boss passes the studs the upper tumbler disengages
A

page_text: from the locking plate and the said plate resuming its normal position brings the.
forward side of the stud e in substantial contact with the boss on the bolt whereby
the bolt is locked in an extended position as illustrated in Fig. 3. In applying the
lock to a bicycle or similar machine a wedge shaped gib H is passed through the
slot in the casing and bolt to an engagement with their forward walls, and the lock,
key-hole upward, is entered by means of the aforesaid slot, over the perpendicular
arm h of the brake-lever H¹ the gib coming in contact with the face of said arm
opposing the head C bringing the front end of the bolt directly opposite the head as
shown in Fig. 1. or as illustrated in fig. 3.
When the lock and gib have been sufficiently wedged upon the lever the gib is
secured to the lever by a set screw has shown in Fig. 4.
When the rider dismounts he applies the brake on the rubber tire and turns the
key in the lock, the bolt of which is thereby forced against the head of the machine
keeping the brake in contact with the tire. Thus it is rendered impossible to ride the
machine without throwing back the bolt.
.
The lock is no trouble to the rider as it is always in place the weight upon the
machine practically amounts to nothing and the attachment may be made an ornament
by nickel-plating or finishing it to correspond with the part to which it is secured.
The key-hole K is made double in order to foil any one attempting to fit a key
to the same.
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 bicycle or similar machine the combination with the brake-lever and head
of a bolt-lock secured to the former, the bolt whereof directly engages the head,
substantially in the manner and for the purpose specified.
2. The combination with the brake lever of a bicycle or similar vehicle, of a lock
having its casing provided with aligning slots to receive one arm of said lever,
substantially as described.
3. In a bicycle or similar machine the combination with the brake-lever and the
head of a lock held borizontally upon the lever provided with a sliding bolt adapted
to engage the head, a gib interposed between one edge of the lever and the opposing
edge of the lock and means substantially as described for actuating the bolt.
4. In a bicycle or similar machine the combination with the brake-lever and head,
of a lock provided with a slotted casing, a slotted sliding bolt having a concaved
front end and boss upon the upper surface and an essentially V-shaped recess in its
longitudinal bead, a spring, actuated locking plate, bearing upon said bolt and
provided with a central aperture to receive said boss and stop arranged in said
aperture, a key post opposite the recess in the bolt and means substantially as
described for securing the lock to the brake-lever.
