COIN-CONTROLLED LOCK.

To all whom it may concern:

Be 1t known that we, J OEL SMITH and ROLLIN C. HOPKINS, citizens of the United States, residing at Batavia, county of Kane, and State of Illinois, have invented certain new and useful Improvements in Coin-Controlled Locks, of which the following is a specification.

Our invention relates to looks, and particularly to coin controlled looks.

The object of our invention is to provide a lock especially adapted for lockers and similar uses, which can only be operated to lock the door after having deposited a coin or slug therein, and in which the key can only be removed. after the bolt is driven to lock the door.

A further object of our invention is to provide a look as mentioned, which cannot be locked a second time, after having been looked and unlocked, without depositing a second coin or slug.

A further object of our invention is to provide a device as mentioned which shall be of simple construction, of low cost to manufacture and one which shall not readily get out of order.

A further object of our invention is to provide a lock characterized as above which may be readily applied to any door and adapted for use with almost any style look.

Other objects will appear hereinafter.

\Vith these objects in view our invent-ion consists generally in a lock having a reciprocating bolt, a pin normally locking said bolt against reciprocation, means operable by a coin or slug for disengaging the pin from the bolt, said means being further operable by the driving of the bolt, for depositing the coin.

Our invention further consists in a device characterized as mentioned, in combination with a stop arranged behind the keyhole to prevent the removal of the key from the look when the bolt is retracted.

Our invention further consists in various details of construction and arrangements of parts all as will be hereinafter fully described and particularly pointed out in the claims.

Our invention will be more readily understood by reference to the accompanying drawings forming a part of this specification and in which,

Figure 1 is an elevation of a lock embodying our invention in its preferred form, illus- Specification of Letters Patent.

trating the same secured to a door, and with a portion of the casing removed, and Fig. 2 is a similar detail view illustrating the parts in the positions they assume after the coin is inserted.

Referring to the drawings, 1 indicates a portion of the door and 2 the casing of a lock secured thereto. 3 indicates the bolt of the lock which may be of any ordinary or preferred form and operated by the key, 4:. Behind the keyhole, 5 we arrange a stop, 6 for the key. It is obvious that the key cannot be removed from the lock except after the bolt is driven to lock the door, as any movement of the key in one direction will drive the bolt and its movement in the opposite direction is arrested by the stop before reaching the keyhole.

Pivotally mounted as at 7 above the lock is a three armed lever, 8. To the end of one arm, 8 of the lever is connected a pin, 9, the end of; which enters a hole, 10 in the bolt, 3, when the. lever is in normal position. The pin, 9'extends through a hole, 11 in the top of the casing, 2, and it is evident that as long as the end of the pin is in the hole, 10 the bolt cannot be reciprocated to lock the door.

Extending in the opposite direction from the arm, 8 is a long arm, 8, the end of which extends into the coin chute, 12. When a coin is inserted it rests upon the end of the arm, 8 and the weight of the coin swings the lever into the position shown in Fig. 2, withdrawing the pin, 9 from the hole, 10, after which the bolt may be freely reciprocated. The initial downward movement of the arm 8" is limited by the third arm, 8' which extends into a slot, 13 in the flange, 14 formed upon the bolt, 3. The slot, 13 is but long enough to permit sufiioient movement of the lever, 8 to withdraw the pin, 9 from the hole, 10, the end walls, 13 13 of the slot serving as stops to limit the movement of said lever.

Before the coin is inserted, a weight, 15 on the arm 8 holds the arm 8 in engagement with the stop, 13 and when the coin is resting upon the arm, 8 it overbalances the weight 15 and brings the arm 8' into engagement with the stop, 13". The limited initial movement thus allowed to the arm, 8 is not sufficient to permit the coin to drop, but as the bolt is reciprocated or driven to lock the door, the arm, 8 is permitted further movement, as it is obvious, this further movement causing the end of the arm, 8 to drop a sufficient distance below the bottom edge, 12 of the side Wall of the chute, to drop the coin into the coin receptacle, 16. After the bolt is driven the key may be removed from the look. When the arm, 8 is relieved of the weight of the coin, the weight, 15 tends to return the lever, 9 to normal position, but its movement is limited by the arm, 8 and the stop, 13. When the bolt is retracted to unlock the door, the pin, 9 drops into the hole, 10 securely locking the bolt against further reciprocation until another coin is dropped into the chute.

17 indicates a casing secured to the door and adapted to cover the complete mechanism and to contain the coin receptacle, 16 which may be locked therein in any suitable manner. It is obvious that the casing, 17 and the casing 2 may be made integrally if desired.

From the foregoing description it will be seen that the device may be applied to any door and used with almost any style of lock having a reciprocating bolt. It is also obvious that the device is particularly adapted for use upon doors of lockers in gymnasiums and other similar places.

Having described our invention what we claim as new and desire to secure by Letters Patent is:

1. In a device of the class described, a lock having a reciprocating bolt, in combination with a lever pivotally mounted adjacent to said bolt, a pin connected to one end of said lever and normally locking said bolt against reciprocation, a coin chute, the opposite end of said lever from said pin extending into said chute, forming a stop for the coin, and a suitable connection between said lever and said bolt for limiting the initial movement of the former and for further moving said lever as the bolt is driven, as and for the purpose specified.

2. In a device of the class described, a lock having a reciprocating bolt, in combination with a coin chute, a lever pivotally mounted adjacent to said bolt and having one end ex tending into said chute, a pin connected to the opposite end of said lever and normally locking said bolt against reciprocation, a third arm on said lever and a pair. of stops on said belt for said third arm, as and for the purpose specified.

3. In a device of the class described, a lock with a coin clutch, a lever pivotally mounted above said bolt and having one end extending into said chute, a pin pivotally connected to the opposite end of said lever and normally locking said bolt against reciprocation, said bolt being provided with an aperture to receive the end of said pin, a longitudinal rib on said bolt and a third arm on said lever extending downwardly, and said rib being apertured to receive the end or" said third arm and forming stops for the same, substantially as described.

4. In a device of the class described, a lock comprising a case and a reciprocating bolt, in combination with a coin chute, a lever pivotally mounted above said case and having one end extending into said chute, a pin pivotally connected to the opposite end of said lever and normally locking said bolt against reciprocation, said bolt and said case being apertured to receive said pin, a third arm extending from said lever into said case, said case being slotted to receive the same, and means on said bolt for limit ing the initial movement of said arm and thereby said lever, substantially as described.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses:

JOEL SMITH. ROLLIN G. HOPKINS.
