Be it known that we, CHARLES C. FREE and NED F. HEATH, citizens of the AUnited States, residing at Denver,in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in Bicycle-Locks.; and wedo hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the artto which it appertains to make `and use the same.

This invention relates to bicycle locks, and has for its object to provide means for securing one or both wheels of a bicycle against movement, of the chain wheel, or any part of the running gear, or movement mechanism which is contributory to the movement of the machine.

With these and other objects in view, the invention consists of the construction and arrangement of the several parts which will be more fully hereinafter described'and claimed.

In the drawings: Figure 1 is a side elevation of a portion of a bicycle, showing the improved lock applied thereto in one of different ways in which it can be applied. Fig. 2 is a top sectional plan view. Fig. 3 is .a

front or face sectional View. Fig. 4 isa detail perspective view of a portion of the locking chain and a round head carried thereby.

. to indicate corresponding partsin the several views.

Referring to the drawings, the numeral 1 designates a casing having at the back thereof a pair of hinged clamping jaws 2 with oppositely disposed lips 3 at their terminating i ends adapted to be engaged by a bolt, rivet or other fastening device tow.; secure the said clamping arms over a portion of the frame.

` @It will be understood that these clamping vsame fast in the casing.

cated a stud 8 on which is `mounted a rotatable chain pulley 9 having` aspring chamber lO in the rear thereof, to receive a spring 11,

one end of which is secured to the said pul. ley and the other end to the rear of the c as- 6o adapted to pass out of the chain slot in thej6`5 lower portion of the casing heretofore referred to and having thereon eithera round or an angular or a square head l5, as fully shown in the accompanyingl drawings, the,

said head 15 being larger in diameter thanjo the chain slot and preventing the entire ingress ofthe chain within the casing.I The said chain is employed to lock the parts of the bicycle or analogous machine againsty f movement and when it is desired to use the` ,75

saine, it is drawn outward from the. casing and causes a rotation of the chain pulley and fa winding action of the spring, and after the'- ehain has been drawn out and caused to engage the movable part of the bicycle or'other 8o machine which it is adapted tolock, the round or square head of the free end of the` chain is caused to engage the slot in the upperend .p

of the casing and passes througha'similar j opening 16 in a spring actuated latch 17 which 85 engages the groove in the head andholds th'e When it is desired to release the head from the latch,a key 18is inserted in the key-hole in the face plate, and by turning the said keyL to bring the opening therein in such position as to permit the head to be withdrawn, it being understood, that the opening in the latch is larger than the head and that` the spring action of said latch causes the wall of the 95 opening to engage the groove in the head and lock the same against withdrawal, until released by the key as stated. 1 1

The chain pulley heretofore described is a frictional pulley, and the edge thereof is enmo gaged by a frictional brake pawl19',whichis. spring actu ated and normally in engagementu the latch is operated 9o with the periphery of the said pulley. This'. brake pawl is fulcrnmed at a suitable pointfand has an end' projecting beyond its fulcru'm to which is, attached the inner end of" a push rod 20,having a' suitable head on the lenter end. When it is desired 'to release'the chain from a securing 'position and store it within the casing of the lock, the push rod 2O is operated to release the brake pawl and permit the chain pulley to operate through the medium of the springA and to wind the zeA Achain thereon automatically, and thereby store said chain within theA casing.

While the lock has been'shown applied to a bicycle, it will'be understood that it'cau be construction can be madeand substituted for those shown and described, without in the Ving witnesses.

least departing from the nature or spirit of the invention'.

Having thus described the invention,what is claimed as new is In a lockofvthe character described, the combination oli a spring actuated chain pulley, a chain in l connection `therewith and adapted to be wound thereon and having a head on thefree end thereof, a lock for enconsist'ing of a spring actuated pawl haring a push rod attached to one end thereof and extending through the casing of the lock, substantially as and forthe pu rposes specified.
