Improvements in Looks for Bicycles or other Velocipedes.
I, GEORGE RILEY FULLER of 147, State Street, Rochester in the County of
Monroe, State of New York, United States of America, Manufacturer of
Artificial Limbs, de hereby declare the nature of this invention to be as
follows:-
My invention is an improved lock for bicycles or other velocipedes, by means of
which the wheel of the vehicle may be conveniently and rigidly held from
turning by applying the locking device preferably to the periphery of the wheel.
Referring to the drawings:-
Figure 1 is a side elevation of a portion of the fork and the wheel of a
bicycle with my improved lock in place, parts being omitted;
Figure 2 a view of the device seen as indicated by arrow in Figure 1,
parts being broken away and the locking-clamp bearing against the wheel;
Figure 3, a cross-section of the fork taken on the dotted line 3-3 in
Figure 1;
Figure 4, a section taken as on the dotted line 4-4 in Figure 1.
Figures 5 to 8, inclusive, show the device with various pieces successively
added;
Figure 9, a section taken as on the dotted line 9-9 in Figure 1, parts being
omitted; and
Figure 10, a view of the clamp, showing the corrugations.
Referring to the parts shown, A is the wheel of a bicycle or other velocipede,
and B the fork, to which latter part my improved lock is shown as being secured
in position to bear upon the periphery of the wheel.
The lock is provided with a frame C to secure it to the fork, said frame being
secured to the fork by means of a lip a and binding screws b b.
c is a sliding clamp turned laterally over the wheel to press the latter, as shown
in Figure 2. This clamp is in one piece or rigid as to its parts, and rests in the
circular inclosing-case d of the lock, and is formed with an opening e within said
case and internal gear-teeth f Figures 1 and 5. At the opposite side, the clamp
is formed with external ratchet-teeth g, which are engaged by a spring-pressed
pawl h within the case. Centrally within the case is a barrel or cylinder i, rigid
with the case, whose axis coincides with the axis of the case.
k, Figure 5, is a pinion occupying the opening e in the clamp, having its teeth
engaging the internal teeth of the clamp to actuate the latter, said pinion being
concentric with and held to turn on the barrel i.
I is a wrench or handle outside of the case, secured rigidly to the pinion by
fastening-screws n n. By means of this handle the pinion may be turned at any
time in a manner to bring the clamp firmly down upon the wheel, as shown in
Figure 2, to firmly lock the wheel and prevent it from turning on its axis.
The ratchet-teeth are formed in such a manner that the clamp may be moved
freely toward the wheel, but will be prevented by the pawl from moving in the

page_text: opposite direction. Then to lock the wheel it is only necessary to turn the
handle as, for instance, from the position shown in full lines in Figure 8 to
the position shown in dotted lines in the figure-the pawl holding the clamp in
position against the wheel.
Within the cylinder i is placed a movable core o, consisting of tumblers or parts
of a lock of suitable kind to be operated by a key or instrument separate from the
lock, carried in the pocket of the rider of the vehicle, which parts, however,
within the cylinder and the key by themselves, form no part of my invention.
Beneath or back of the clamp c is shown a sliding piece p Figure 1, constituting
an actuator for the pawl, provided with a rigid pin r to bear against the pawl in a
manner to turn the latter away from the clamp. This sliding piece has a part
extending near to or within the cylinder, so that the sliding piece may be moved
against the pawl by the key, the latter being inserted in the key-hole t. The
piece p is provided at one end with a slender spring n to hold it normally back
from the pawl, so that the latter may be free to engage the clamp. Now to unlock
the bicycle it is only necessary to insert the key in the core o and turn the
actuator p against the pawl to release the clamp. The pawl is pressed against the.
clamp by a spring u, rigid with the case d.
The case d is open at one side, but formed with a rigid back v, and is secured to
the frame C by short clamping-screws w. Figures 1 and 9, passed through the
back and threaded in the frame. Figure 5, shows a thin circular plate or
diaphragm a, placed against the clamp cand formed with holes b' over the screws w.
Resting upon this diaphragm is the pinion the tooth portion of which is within
the space e of the clamp, as above described. The ring or part c¹ of the pinion. is
formed with a peripheral groove, as shown in Figure 4, and an involute spring d
occupies said groove in part, having its inner end inserted in the pinion. This
spring has its outer end inserted in a hole e' in the diaphragm, and a pin f', rigid
with the case and projecting through the diaphragm, also serves to hold the
spring.
9, Figures 6 and 4, is a thin plate placed over the spring d' to inclose the
latter between the plate and the diaphragm. This plate rests against a circular
shoulder of the pinion and serves when in one position as a dust-guard to cover
openings leading into the interior of the case. This dust-guard is held to turn
upon its bearings on the pinion, and is provided with a rigid pin h¹ by means of
which it may be turned. It is also formed with holes to', which register with the
holes b¹ in the diaphragm when the dust-guard is in a certain position. Outside of
the dust-guard is the circular cap or cover i¹ for the case, held rigidly to the latter
by screws k¹. This cap is also formed with holes !, registering with the holes 6¹
in the diaphragm, through which an instrument may be passed to turn the screws ir.
One of the holes, is formed with extensions n¹ on opposite sides to accommodate
the pin A¹ in the dust-guard, so that the latter may be turned at any time to either
cover or uncover the holes in the cap. As shown in Figures 7 and 8, the pin
is turned to the left, and the holes leading into the interior of the inclosing-case,
are closed.
Figure 6, shows the dust-guard in full lines turned to the right, in which
position the holes w¹ register with the holes 61 of the diaphragm and l' of the
сар 21.
When these holes all register and the clamp is raised out of the way, a
screw-driver may be passed through them to turn the screws to to remove the case
from the frame C.
The dust-guard is formed with peripheral notches o', Figure 6, so as to clear
the screws, which pass through it and admit of its being turned, as above
described.
The screws k', that hold the cap ¹ to the case d, are threaded in the former and
have their heads resting in countersink-openings in the back of the case and next
the frame C. Figure 9. By this means the heads of the screws are covered by the
frame, which renders them inaccessible and prevents the lock being opened or
tampered with by unauthorized persons; also, when the clamp is brought down

page_text: upon the wheel to lock it by means of the handle 1, as above described, it covers
the screws w, as shown in Figure 5, so that while the wheel is locked and left
standing no person can loosen said screws w, and remove the case from the frame C
to unlock the wheel.
I form the frame with a perforated projecting lug pl at its rear surface, Figures 2
and 3. This lug is formed with an opening and the clamp is provided with a
pin to enter said opening when the clamp is brought down upon the wheel to
lock the latter. By this contrivance links t¹ of a chain may be held by the pin,
so that the vehicle may be chained to a post or other fixed part (the chain passing
around said post or fixed part) at the same time that the wheel is locked by the
clamp. I form the surface of the clamp in contact with the wheel with teeth or
corrugations u', Figure 10, to sink into the rubber tire of the wheel, so as to more
firmly hold the latter. The involute spring d', acting upon the pinion, serves to
throw the clamp up off the wheel when the clamp is released from the holding-
pawl by the key, as above stated.

COMPLETE SPECIFICATION.
Improvements in Locks for Bicycles or other Velocipedes.
I, GEORGE RILEY FULLER of 147 State Street, Rochester, in the County of
Monroe, State of New York, United States of America, Manufacturer of
Artificial Limbs, 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 is an improved lock for bicycles or other velocipedes, by means of
which the wheel of the vehicle may be conveniently and rigidly held from turning
by applying the locking device preferably to the periphery of the wheel.
Referring to the drawings filed with the Provisional Specification,-
Figure 1 is a side elevation of a portion of the fork and the wheel of a bicycle
with my improved lock in place, parts being omitted;
Figure 2 a view of the device seen as indicated by arrow
in Figure 1, parts
being broken away and the locking-clamp bearing against the wheel;
Figure 3, a cross-section of the fork taken on the dotted line 3-3 in Figure 1;
Figure 4, a section taken as on the dotted line 4-4, in Figure 1;
Figures 5 to 8, inclusive, show the device with various pieces successively
added;
Figure 9, a section taken as on the dotted line 9-9 in Figure 1, parts
being omitted, and
Figure 10, a view of the clamp, showing the corrugations.
Referring to the parts shown, A is the wheel of a bicycle or other velocipede,
and B the fork to which latter part my improved lock is shown as being secured
in position to bear upon the periphery of the wheel.
The lock is provided with a frame C to secure it to the fork, said frame being
secured to the fork by means of a lipa and binding screws b b.
c is a sliding clamp turned laterally over the wheel to press the latter, as shown
in Figure 2. This clamp is in one piece or rigid as to its parts, and rests in the
circular inclosing-case d of the lock, and is formed with an opening e within said
case and internal gear-teeth f, Figures 1 and 5. At the opposite side, the clamp is
formed with external ratchet-teeth g, which are engaged by a spring-pressed pawl
within the case. Centrally within the case is a barrel or cylinder i, rigid with the
case, whose axis coincides with the axis of the case.
k, Figure 5, is a pinion occupying the opening in the clamp, having its teeth

page_text: engaging the internal teeth of the clamp to actuate the latter, said pinion being
concentric with and held to turn on the barrel i.
7 is a wrench or handle outside of the case, secured rigidly to the pinion by
fastening-screws nn. By means of this handle the pinion may be turned at any
time in a manner to bring the clamp firmly down upon the wheel, as shown in
Figure 2, to firmly lock the wheel and prevent it from turning on its axis.
The ratchet-teeth are formed in such a manner that the clamp may be moved
freely towards the wheel, but will be prevented by the pawl from moving in the
opposite direction. Then to lock the wheel it is only necessary to turn the handle l,
as for instance, from the position shown in full lines in Figure 8 to the position
shown in dotted lines in the figure, the pawl holding the clamp in position against
the wheel.
Within the cylinder i is placed a movable core o consisting of tumblers or parts
of a lock of suitable kind to be operated by a key or instrument separate from the
lock, carried in the pocket of the rider of the vehicle, which parts, however, within
the cylinder and the key by themselves, form no part of my invention.
Beneath or back of the clamp c is shown a sliding piece p, Figure 1, constituting
an actuator for the pawl, provided with a rigid pin to bear against the pawl in
a manner to turn the latter away from the clamp. This sliding piece has a part
extending near to or within the cylinder, so that the sliding piece may be moved
against the pawl by the key, the latter being inserted in the key-hole t. The
piece p is provided at one end with a slender spring to hold it normally back
from the pawl, so that the latter may be free to engage the clamp. Now to unlock
the bicycle it is only necessary to insert the key in the core o and turn the actuator p
against the pawl to release the clamp. The pawl is pressed against the clamp by
a spring u rigid with the case d.
The case d is open at one side, but formed with a rigid back v, and is secured to
the frame C by short clamping-screws 10, Figures 1 and 9, passed through the
back and threaded in the frame. Figure 5 shows a thin circular plate or
diaphragm a', placed against the clamp c and formed with holes 6' over the screws to.
Resting upon this diaphragm is the pinion k, the tooth portion of which is within
the space e of the clamp, as above described. The ring or part o' of the pinion is
formed with a peripheral groove, as shown in Figure 4, and an involute spring d
occupies said groove in part, having its inner end inserted in the pinion. This
spring has its outer end inserted in a hole e' in the diaphragm, and a pin, rigid with
the case and projecting through the diaphragm, also serves to hoid the spring.
9', Figures 6 and 4, is a thin plate placed over the spring to inclose the latter
between the plate and the diaphragm. This plate rests against a circular shoulder
of the pinion and serves when in one position as a dust-guard to cover openings
leading into the interior of the case. This dust-guard is held to turn upon its
bearings on the pinion, and is provided with a rigid pin by means of which it
may be turned.
It is also formed with holes w¹, which register with the holes b
in the diaphragm when the dust-guard is in a certain position.. Outside of the dust-
guard is the circular cap or cover for the case, held rigidly to the latter by
screws k. This cap is also formed with holes ", registering with the holes 6' in the
diaphragm, through which an instrument may be passed to turn the screws w. One
of the holes l' is formed with extensions n' on opposite sides to accommodate the
pin ¹ in the dust-guard, so that the latter may be turned at any time to either
cover or uncover the holes l' in the cap ¹. As shown in Figures 7 and 8, the pin
is turned to the left, and the holes leading into the interior of the inclosing-case
are closed.
Figure 6 shows the dust-guard in full lines turned to the right, in which position
the holes register with the holes 6 of the diaphragm and 1 of the cap i'.
When these holes all register and the clamp is raised out of the way, a screw-
driver may be passed through them to turn the screws w to remove the case from
the frame C,

page_text: The dust-guard is formed with peripheral notches o¹, Figure 6, so as to clear
the screws, which pass through it and admit of its being turned, as above
described.
The screws ¹, that hold the cap to the case d are threaded in the former and.
have their heads resting in countersink-openings in the back of the case and next
the frame C, Figure 9. By this means the heads of the screws are covered by
the frame, which renders them inaccessible and prevents the lock being opened or
tampered with by unauthorized persons; also when the clamp is brought down
upon the wheel to lock it by means of the handle 1, as above described, it covers
the screws w, as shown in Figure 5, so that while the wheel is locked and left
standing no person can loosen said screws w and remove the case from the frame C
to unlock the wheel.
I form the frame with a perforated projecting lug p'at its rear surface, Figures 2
and 3. This lug is formed with an opening and the clamp is provided with a
pin s to enter said opening when the clamp is brought down upon the wheel to
lock the latter. By this contrivance links t' of a chain may be held by the pin,
so that the vehicle may be chained to a post or other fixed part (the chain passing
around said post or fixed part) at the same time that the wheel is locked by the
clamp. I form the surface of the clamp in contact with the wheel with teeth or
corrugations u¹, Figure 10, to sink into the rubber tyre of the wheel, so as to more
firmly hold the latter. The involute spring d', acting upon the pinion serves to
throw the clamp up off the wheel when the clamp is released from the holding-
pawl by the key, as above stated.
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
