COIN-CONTROLLED LOCK.

Application filed August 31, 1912.

To all whom it may concern:

Be it known that I, OLIN A. DOZIER, a citizen of the United States, residing at Athens, in the county of Clarke and State of Georgia, have invented a certain new and useful Coin-Controlled Lock, of which the following is a specification.

This invention relates generally to coin controlled locks, and particularly to looks adapted for use on the doors of lockers or other compartments located in railway stawithdrawn after the insertion of a coin and the lock-bolt has been automatically shot to lock the door, and it consists of the parts and combinations of parts hereinafter described and claimed.

In the accompanying drawings, forming a part of this specification, Figure 1 is a side elevation of the front side of the lock showing the housing for the tumblers partly broken away, and the bolt of the lock in its unlocking position; Fig. 2 is a similar view, from the opposite side, with the side casing removed; Fig. 3 is an elevation of one side of the division plate with the operative parts I removed; Fig. 4 is a similar view with the.

parts in place and the bolt shown in dotted lines in its locking position; Fig. 5 is a de tail perspective view of the locking bolt; Fig. 6 is a detail perspective view of the tumbler housing; and Fig. 7 is a vertical section through the housing and the barrel for the key.

Similar letters refer to similar parts throughout all the views.

This invention may be applied to any preferred or suitable style of lock in which the bolt is normally held retracted or in its unlocking position and under the influence of a spring adapted to protract or throw the bolt into its locking position immediately upon the release of the bolt. In the drawings is shown a simple style of such a lock comprising a bolt A, a spring a, for operating or throwing the bolt, tumblers b, and a housing 0 for the tumblers and spring, the

latter being so arranged as to normally tend to protract the bolt when the latter is released by the mechanism hereinafter de scribed.

As shown the bolt A is supported and arranged to slide on posts (Z and its longitudinal movement is limited by a post d extending into a longitudinal slot 9 formed in the bolt, said post (Z also serving as a pivot pin for the tumblers. The posts (Z and d are secured to and project from a division plate B and to which plate the housing 0 is also secured.

The plate B serves as a division plate between the actual locking mechanism and the means for operating the same, and is formed with a recess f at its edge near the top at one end adapted to receive the head of a plunger C, the shoulder g of said recess forming a stop to limit the inward movement of the plunger. In rear of the recess f a slot h is formed in the plate B to receive and guide a pin '2', which connects the tail of the plunger C to the short arm j of a lever D arranged on the opposite side of the plate and pivoted on a post 7c projecting therefrom. The lever D is normally held outward by a spring t engaging the same, and is formed with a. laterally extending arm Z having its end slightly inclined to adapt it to fit against the edge of the coin K used to operate the look, as shown in Fig. i, and

as will be explained hereinafter. The plate B is also formed with a longitudinally ex tending slot on to receive a pin a projecting laterally from near the rear end of the bolt A and extending through said slot m and into a longitudinal slot 0 formed in the arm ,2) of a lever E fulcrumed on a post 1 projecting from plate B. The edge of the lower wall of the slot 0 is formed with a recess 0 adapted to receive the end of the pin 91., the said pin engaging the end of said recess 0 to hold the bolt in its unlocking position. The arm 7) of the lever E is held in contact with the pin 11, by a spring 8 pressing thereagainst and a post 8 is arranged below said arm to limit its downward swing or movement.

As stated both levers are spring operated, the lever D being held out of the path of the coin K by the spring t, which also, through the connecting pin i, normally holds the plunger C in its protracted position as shown in Fig. 1. The arm p of the lever E is normally held up and in engagement with the pin n of the bolt by the spring 5, said pin, when bolt is in its unlocking position, resting in the recess 0 and against one end of the said recess in order to hold said bolt against the action of the bolt spring a until the lever E is shifted or turned on its fulcrum to release said pin a. The plate 13 is also formed with an opening at for the end of the stem of the key F and a coinciding opening is formed in the rear casing of the lock. The bolt is formed with a notch (Z to receive the bit of the key F.

The housing 0 is formed or provided with a barrel K in the outer end of which a groove M is formed to receive a circular plate or disk L in which akeyhole is formed. The walls of the groove M are formed with a notch or slot P to coincide with the bit slot of the keyhole when said disk is turned so that said slots are in alinement, there y permitting the insertion and withdrawal of the key. a

As shown spacing bars I, J, and J are arranged along the edges of the division plate B to which a side plate may be secured to inclose the key releasing parts, and a similar plate may be secured at the opposite side of the plate B to inclose the locking bolt and plunger.

A vertical coin chute w is formed at one side of the division plate, the end walls of which are formed by the spacing blocks, 1, J, and J and the edge of the elongated arm of the lever E, the opening w being for the insertion of the coin and the opening 'w for the escape of the same into a receptacle, not shown.

The distance between the edge of the le- I ver E and the key stem controls the size of the coin that may be used to operate the lock. Thus, if the lock is designed to be operated by a nickel the opening 14 for the key stem is so located that a nickel cannot pass between it and the adjacent arm of the lever E, but will rest partly on the key stem and against the lever E, and can only pass after the plunger C has operated to press the lever D against the coin and, through the latter, turn the lever E on its fulcrum and against the pressure of its spring 8, thus releasing the pin a from recess 0 and permitting the spring a to throw or protract the locking bolt A, and the coin to pass down the chute, whereas a coin of less diameter will not be arrested and will pass through the chute.

In operation, the doors of the lockers provided with the lock are left open when not in use, with the locking bolt retracted and with the key in the lock. A person desiring to store a parcel in the locker first places the same in the locker and then inserts a coin in the coin chute and pushes the door shut.

' In shutting the door the plunger 0 strikes against the stile of the door casing and is forced inwardly and through its pin 2' turns the lever D against the pressure of the spring t and causes the end of the lever arm Z to engage the edge of the coin. The coin re sts'on the key stem and against the lever E and as the lever D is turned its arm Z forces the coin against the lever E and turns the same on its fulcrum until the pin '21. of the locking bolt is released from the end of the recess 0. When the parts are the position described the coin is released and drops downward, and the release of the pin 7% permits the spring a to throw the bolt A into its catch on the door casing stile and locks the door. The protracting of the lookin bolt causes the key F tosmake a quarter turn, by reason of the engagement of its bit with the notch (Z of the bolt, carrying with it the disk L, so as to bring the key bit to a horizontal position and in line with the notch P in the rim of the barrel K, so that the key may be withdrawn and carried ofi by the person depositing the coin.

VFhen it is desired to open the locker the key is inserted in the barrel K and given a turn so as to operate the tumblers to re-- lease the locking bolt and to retract the latter, thus permitting the door to be swung open. The act of turning the key throws the bolt into the position shown-in Fig. 1, with the bolt held against protraction by the engagement of its pin n with'the end of the recess 0, and brings the key bit to a vertical position in the notch (Z of the bolt thus holding the key against being turned or withdrawn, untilacoin is dropped 7 in the chute and the door swung closed.

It is obvious that changes may be made in the arrangement and location of the parts and equally good results obtained without departing from the spirit of the invention and it is not desired that the invention be restricted to the exact location or arrange ment shown.

Having thus described my invention what I claim is:

,1. A coin controlled lock comprising a casing, a plunger reciprocable in said casing and normally projecting therefrom when the door is open, a spring operated locking bolt, a latch member arranged to hold the locking bolt releasably against protraction, and a coin controlled connection between said member and plunger and arranged to move the member to releasing position upon retraction of the said plunger by contacting with the door stile.
