Improvements in Velocipede Locks.
I, MAGULER BUTLER, of Aqueduct Building, Aqueduct Street, Rochester,
County of Monroe, State of New York United States of America Machinist
do hereby declare the nature of this invention and in what manner the same is to
he performed to be particularly described and ascertained in and by the following
statement :-
My invention relates to devices for securing a bicycle in such a manner that it
may not be readily purloined ; and the object of my invention is to provide a lock
for bicycles that may be conveniently carried as a fixture on the machine and
locked in such a manner that one of the wheels of the bicycle may be prevented
from revolution and which may be quickly and easily operated.
I attain this object by means of the mechanism illustrated in the accompanying
drawing, in which:
Fig. 1, is an elevation of my lock with parts of the front plate broken away.
Fig. 2, is a section along the line 1-1 on Fig. 7.
Fig. 3 is a detail view of the sliding bolt 5.
Fig. 4 is a view of the key.
Fig. 5 is a detail view of the spring 9.
Fig. 6 is a detail view of the locking bolt 8, and
Fig. 7 is a view of a bicycle with my lock in position, parts of the bicycle
being broken away.
Similar letters refer to similar parts throughout the several views
To each of the sections of a bifurcated post 11, 11, I secure the lock by means of
the clamps 4, which are secured at their ends by the bolt 4* or in any suitable
manner, the clamps 4 being capable of springing about one of the sections of the
bifurcated post 11, and having a lug 4 adapted to enter the T slot 12 in the arins 3
secured to the lug, said lug 4b having a head which will enable it to pass into
the slot 12 and when placed in position therein, the head on said lug will
overlap the sides of the arms 3, adjacent to the T slot 12 and hold the arms firmly
i: connection with the clamps 4.
I usually arrange four clamps to each lock engaging with the sides of the
bifurcated posts in the manner shown in Fig. 7, in such a manner that the lock
proper surrounds the tire and felly of the forward wheel of a bicycle.
The lock proper is composed of a circular tube I open a short distance at 13.
Within the tube I place a sliding bolt 5 semicircular in form adapted to move
easily within the tube I. To one end of the sliding bolt 5, I attach a spring 7,
the other end of said spring 7 being secured to a lug or other rigid support 14 in said
tube and so arranged that the tension of the spring will tend to draw the sliding
bolt 5 within the tube leaving the opening 13 unobstructed. Near one side of the
tube adjacent to the opening 13 I arranged a locking bolt 8 pivotally supported and
so arranged that said locking bolt may engage with the indent 15 in the periphery
of the sliding bolt 5, when the sliding bolt 5 is drawn against the tension of the
spring 7, closing the opening 13.
In contact with the locking bolt 8, I arrange a spring 9 adjusted in such a manner
that the locking bolt 8 will be by the operation of said spring forced in contact with
the side of the sliding bolt 5. I also arrange certain tumblers 16 in connection with
the end of the locking bolt 8 opposite that which is arranged to come in contact

page_text: with the side of the sliding bolt 5, which tumblers may be caused to engage with
the key 10 adapted to be inserted within the recess occupied by the locking bolt 8
to move on its pivot against the tension of the spring 9, forcing the locking bolt 8
from contact with the indent 15 in the sliding bolt 5.
To the side of the sliding bolt 5 I arrange a handle 6, which moves within a slot
in the side of the tube I".
The operation of my lock is apparent. When the lock is in position on the
bicycle, the wheel may be prevented from rotation by drawing down the handle 6
against the tension of the spring 7, causing the sliding bolt 5 to close the opening 13
and come in contact with the spokes on the wheel beneath the tire, preventing the
wheel from rotation; said sliding bolt will be held in position by the locking bolt 8,
which will catch the sliding bolt at the indent 15 therein. To release the sliding
bolt, it is simply necessary to insert the key 10, the mere insertion of the key
releasing the locking bolt from contact with the sliding bolt, when the spring 7
will immediately and forcibly withdraw the sliding bolt, and the machine is ready
for operation.
Having now particularly described and ascertained the nature of this said
invention and in what manner the same is to be performed I declare that what I
claim is
1. In a lock for bicycles, a circular tube baving part broken away leaving an
opening therethrough, a sliding bolt adapted to reciprocate within said tube,
a spring attached to said sliding bolt, said sliding bolt adapted to close said
opening against the tension of said spring, with a lock adapted to hold said sliding
bolt in said position, substantially as described and for the purpose set forth.
2. In a lock for bicycles, a suitable ring, a recess in said ring, a sliding bolt
adapted to move in said recess, a spring attached to said sliding bolt and secured to
said ring within said recess, a part of said ring broken away, a means for attaching
said lock to the bifurcated post of a bicycle in such a manner that the lock may be
held in position with the tire and felly of the forward bicycle wheel encircled by
said ring and so arranged that when the lock is closed, the revolution of said wheel
is interfered with, substantially as described and for the purpose set forth.
3. A bicycle lock consisting of a recessed ring, sliding bolt located in the
recess, and a spring detent, substantially as described and for the purpose set
forth.
4. A bicycle lock consisting of a ring, a recess therein, a bolt, spring detent, and
a spring attached to the bolt and adapted to be put in tension by sliding a bolt and
locking the device, substantially as described and for the purpose set forth.
5. In a bicycle lock, a ring, a bolt recessed therein, a spring put in tension by
the locking of said bolt, an arrangement for mounting said bolt consisting of clamps
adapted to fit about the two arms of the bifurcated post held in position by suitable
pins or bolts, a lug on each of said clamps adapted to pass within the T shaped
slots within the arms secured to said ring, substantially as described and for the
purpose set forth.
