BICYC LE-STAN D.

srrzcirrcn'rxon forming part of Letters Patent No. 614,431, dated November 22, 1898.

Application filed "August 4;, 1897- Serial No. 647,055- (NO model-l To all whom, it may concern: I

Be it known that I, DOW B. AUSTIN, a citizen of the United States, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Coin-Controlled Looks for Bicycle-Stands; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improved coincontrolled lock adapted to be used in bicyclestands; and its object is to provide a lock having a bolt having much greater throw than usual, and thus adapted to pass across the space between the posts of a bicycle-stand and through the Wheel of a bicycle to secure the latter in place, to provide means whereby the key will be retained in the lock and prevented from operating the same when unlocked until allowed by a coin, and to provide the same with certain other new and useful features hereinafter more fully described, and particularly pointed out in the claims, reference being had to the accompanying drawings, in which- Figure 1 represents a side elevation of a suitable bicycle-stand with my improved lock attached thereto; Fig. 2, a vertical section of the same onthe line 2 2 of Fig. 1; Fig. 3, an elevation of the lock with one side of the case removed; Fig. 4, an enlarged horizontal sectional detail through the eccentric, and Fig. 5 an enlarged detail of the key.

Like letters refer to like parts in all of the figures.

A represents any suitable bicycle-stand having parallel vertical posts between which to place a bicycle-wheel. This stand forms no part of my present invention and is only shown to illustrate the operation of the lock.

B represents the casing of the lock, attached to the stand by any suitable fastenings G and in such a position that when the bolt of the lock is thrown outward it will pass across the space between the posts and through a bicycle-wheel and enter a suitable opening in the opposite post. I secure sufficient throw to said bolt by means of a novel mechanism, in combination witha coin-controlled locking mechanism, as hereinafter described.

The bolt D moves longitudinally in openings in the case B and a guide-block S and is provided with a pin T to engage the case and limit its outward movement, a pin J to engage the operating-lever H, and a lug U to engage and operate the counter V, said counter being of any convenient construction. The lever H is provided with a slotted upper end engaging the pin J to throw the bolt D and is pivoted interinediately at I and provided with a stud K at its lower end to engage the transverse slot L near the middle of a latch L, said latch having at one end an adjustable weight N and at the other end an upturned end 0 to engage a stop P on the lower end of the coin-chute P. Said latch is also provided with a slot L, engaged by a pin M, and is pivoted and longitudinally movable upon the said pin. The lever H is operated to throw the bolt by means of a connec'ting-rod G, pivoted at one end to said lever near the pivot I and having at its oppo site end a strap G, surrounding an eccentric E, mounted on a rotative plug E, jonrnaled in the case and provided with a key-slot E, adapted to receive a flat keyF, provided with projections F at one side, the projection nearest the end having an inclined side, as shown inFig. 5. W'ards Q,supported by the pins Q, engage grooves in said plug and are provided with notches Q to permit the passage of the projections on the key, which projections engage one or more tumblers R to engage the slot E and are held in engagement therewith by springs R.

G is a lug on the case to engage the rod G and prevent its further downward movement.

P is a coin-chute terminating at its lower end above the end 0 on the latch Land provided with an incline I to guide the latch into engagement with the stop P.

X is a curved partition to retain the coin above a door W in the bottom of the case B, said door being pivoted to the case at one end and secured in closed position at the other end by any suitable lock Y.

B is an opening in the case adjacent tothe plug E to permit the passage of the projections F on the key.

The operation of my device is as follows: When the bolt is projected from the case, as shown in Fig. 3, the key-slot in the plug, the

opening B, and the notches Q in the wards are all adjacent to each other, and the key maybe removed or inserted. The rod G rests on the lug G, and the tumbler R engages the key-slot in the plug, and thus prevents retraction of the bolt, except by a suitable key, which key, when inserted in the slot E, lifts the tumbler from engagement with the slot and releases the plug, the key turning with its projections F at the respective sides of the wards. Thus as the plug is turned, rotating the eccentric and retracting the lever II, the forked end of said lever travels sufficiently to fully withdraw the bolt D within the lock. The lower end of said lever moves the latch forward, and its upturned end 0 is raised by the weight N into engagement with the stop P, being guided to place by the incline P. The latch L now holds the various parts in the position indicated by dotted lines in Fig. The projections of the key are now turned away from the opening B and, engaging the inner side of the case, prevent withdrawal of the key until again turned to project the bolt D. A coin of suitable weight inserted in the chute P will pass down and engage the end 0 of the latch N and disengage the same from the stop P. The bolt D can then be projected by turning the key to the first position described and the key removed. Thus while a bicycle is secured by the lock the key is released, and when the bicycle is released the key is retained, and a coin must be inserted before another bicycle can be secured by the lock. The counter is turned one point every time the bolt is withdrawn, and thus indicates the number of coins that should be found in the lower part of the lock when the door Wis released by a suitable key inserted in the lock Y.

Having thus fullydescribed my invention, what I claim, and wish to secure by Letters Patent, is-

1. In a coin-controlled lock for bicyclestands, a locking mechanism having a limited movement, a bolt having a much greater movement, a pivoted lever connected to said bolt at a distance from its pivot and connected to the locking mechanism near its pivot, and coin-released mechanism for holding said le ver, substantially as described.

2. In a coin-controlled lock for bicyclestands, a locking mechanism having a limited movement, a bolt having a much greater movement,a lever pivoted intermediately and engaging said bolt near one end and also connected near its pivot to the locking mechanism, a latch pivoted to the other end of said lever, a stop engaged by said latch, and a coin-chute above said stop, substantially as described.

3. In a coin-controlled lock for bicyclestands, a casing, a longitudinally-movable bolt in the same, a lever engaging said bolt,

means for locking said lever and releasing the same by a coin, and an eccentric to operate said lever, substantially as described.

4. In a coin-controlled lock for bicycle stands, a bolt having an extended longitudinal movement, a lock having a much less movement, a lever having a pivot and engaging said bolt near one end, and connected to said lock near said pivot and operated by said lock, a latch connected to said lever to hold the same, and a coin-chute, substantially as described.

5. In a coin-controlled lock for bicyclestands, a bolt to engage and hold the bicyclewheel, a pivoted lever engaging and moving said bolt, a latch connected to said lever, a coin-chute adjacent to said latch, a key-operated rotative plug, an eccentric mounted on said plug, a strap on said eccentric a rod connecting said strap and the lever, substantially as described.

6. In a coin-controlled lock for bicycle stands in combination with a longitudinallymovable bolt to secure the bicycle, and a pivoted lever to operate said bolt, and a lock connected to said lever to operate the same, a coin-chute having a stop near its lower end, a latch having a longitudinal slot and a transverse slot and engaging said stop, a pin in the case engaging the longitudinal slot in the latch, and a pin on said lever engaging the transverse slot in the same, substantially as described.

7. In a coin-controlled lock for bicyclestands, the combination of a longitudinallymovable bolt having a pin, a lever having a slotted upper end engaging said pin, an intermediate pivot, and a pin at its lower end, a coin-chute and a stop, a latch having a longitudinal slot engaging a fixed pin, and a transverse slot engaging the pin in the lever, and an adjustable weight, and an upturned end engaging the stop, a key-operated rotative plug, wards and tumblers engaging the same, an eccentric on said plug, a strap on said eccentric,and a rod connecting said strap and lever, substantially as described.

8. In a coin-controlled lock for bicycle stands, a case having journal-openings and a lateral opening, a rotative plug journaled in said openings and having a key-slot, wards having notches, said lateral opening, slot and notches beingin line when the device is locked and out of line when the same is unlocked, and coin-released mechanism to hold the device in unlocked position, substantially as described.
