BICYCLE-LOCK.

SPECIFICATION forming part of Letters Patent No. 558,467, dated April 21, 1896. Application filed September 4, 1895. Serial No. 561,387. (No model.)

said yokes inclose said tires and revolution of the wheels.

The operation will be readily understood from the foregoing description, when taken in connection with the accompanying drawings. The rings M are mounted on the rods N and O of the bicycle-frame, and are free to slide thereon, except when the lock is applied or in use. In order to apply the lock, it is only necessary to depress the hinged ends of the bars A and B into a horizontal position, as shown in dotted lines in Fig. 1,when the locking-latch K will enter the casing D through the slot G and engage with the lockbolt E, as shown in Fig. 3, in which position the machine will be locked, and the wheels thereof cannot revolve by reason of the yokes P, which press upon the tires thereof, and whenever it is desired to unlock the machine it is only necessary to apply a properly-constructed key and throw back the bolt E and raise the bars A and B to the position shown in full lines in Fig. 1. The rings M may be so formed as to be detachable from the rods N and O, and it will thus be seen that I ac- T0 ctZZ whom it may concern: prevent the Be it known that I, HARRY 'lanvrrv ADAMS, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Bicycle Locks, of which the following is a specification, reference beinghad to the accompanying drawings, forming a part thereof, in which similar letters of reference indicate corresponding parts.

This invention relates to bicycle-locks; and

the object thereof is to provide an effective struction and operation and which may be readily attached to a bicycle-frame without changing the construction thereof.

The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which- Figure 1 is a side elevation of a bicycle provided with my improved lock; Fig. 2, a plan view of the lock, and Fig. 3 a sectional detail thereof.

In the practice of my invention I provide two similar bars A and B, which are hinged together at one end, as shown at C, and secoinplish the object of my invention by means cured to the hinged end of the bar Ais an obof a device which is simple in construction and operation and which is also comparatively inexpensive.

My invention is not limited to the exact form and arrangement of parts shown and de scribed, and I therefore reserve the right to make all such alterations therein and modifications thereof as fairly come within the scope of the invention.

Having fully described my claim and desire to secure by entlong rectangular casing D, in which is located a sprin geoperated lock-bolt E, provided with a projecting shoulder F and a longitudinal slot G in the top thereof.

Secured to the hinged "end of the bar B is a casing H, which is open on the lower side thereof, and preferably open at its outer end, and secured to the top thereof is an inwardlydirected latch K, adapted to operate in connection with the lock-bolt E, and formed in the top of said casing His akeyhole L,through invention, 1 Letters Patwhich a properly-constructed key may be m- 1.
