COIN-CONTROLLED? LOCK.

srncrnrcATIoN refining part of Letters Patent No. 651854, dated June 19, 1900.

Application led May 2, 1898i Serial No. 679,421. (No modeL To ILZZ whom t may concern:

Be it known that l, EDWARD M. HARRISON, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Coin- Controlled Lock, of which the following is a specication.

My invention relates to locks whose action is controlled by the introduction of ordinary coins or of thin disks of suitable material other than coins which may serve the same purpose. My object is to provide a simple combination of parts for this purpose having a high degree of eflciency and which may be produced at a low cost, thus adapting it to a wider range ot' use than is possible with the more costly kinds of locks.

My new look is hereinafter fully described, and illustrated in the accompanying drawings, in whichv Figure l is avertical section of the case on broken line 7 8, Fig. 4, and showing'an elevation of the operative mechanism attached to the inside front cover of the case looking in the direction indicated by arrow 9, Fig. 4. The mechanism is shown in the open or unlocked position in Fig. l. Fig. 2 is same section and elevation as Fig. l, but with a key in the keyhole and turned around to a vertical position opposite to the position it had when first inserted and causing the operative parts of the lock to assume the position necessary to expel a coin or disk from the coinslot, and thereby operate the key-latch. Fig. 3 is a vertical section of a portion of the lockcase as in Fig. 1 with the operative parts in elevation and in the locked position.V Fig. 4 is a plan of the lock-case, showing a loop or hasp pivotally attached thereto. Fig. 5 is a plan of the keylatch,which is fully described hereinafter. Fig. 6 is a side elevation of the end of the hasp or loop, showing a notch in which the locking-bolt engages.

Similar letters indicate like parts throughout the several views.

The main body of case A in this instance is rectangular in form; but the top portion thereof is provided with a projection in which is located the coin-slot B, which is in communication with the interior of the case.

At C is a bolt which is mounted to slide -means of spring E.

longitudinally in bearings at Cand C2. Bolt C is provided with a slot, (indicated by the broken lines 03,) down through which is disposed a pin D, which is firmly secured to the side of the lock-case and projects outwardly beyond slide-bolt C, and its outer end serves as a pivotal center upon which is mounted the key-latch E, the latter being yieldingly held against the pressure of the key F by Projecting from the inside of caseAis a pin G, upon which is mounted a safety-detent H, which is yieldingly held in the severalA positions shown by the action of spring H.

At J is a shaft pivotally mounted in the two lugs J and J2, which project from the case,

the shaft terminating at the top endin adouble handle K, which may be grasped to turn shaft J, and therebyinsert the terminal end of hasp L into and through hole Ain the case, where the hasp may be engaged by sliding bolt C and held in the locked position, as shown in Figs. 2 and 3, or the terminal end ot' the hasp when disengaged from the locking-bolt C may be withdrawn by a movement of the handle K the reverse of that above described, when the hasp will stand in the openposition.

In operation when the parts are in the unlocked position (shown in Fig. l) if a coin M is dropped into slotB it will fall to the position shown, resting against the side Wall of the slot at one side and against the lower terminal end H2 of detent H and under the hook at the end E2 of key-latch E, the coin being prevented from further descent by the terminal end H2 of detent H being in contact with the wall of the slot. If now key F is inserted in keyhole F, Fig. l, and turned in the direction indicated by` arrow N, it will first contact with the lower edge of key-latch E and lift the left-hand end portion E4 and cause the opposite end portion at the hook E2 to descend and force coin M downwardly between the wall of the slot and the end H2 of detent H,

which action releases the detent from the notch P in bolt C and permits the bolt to slide outwardly or from right to left, Fig. 2, to the position shown. tion at Q on bolt C will engage with detentlever H and turn it to the position shown, when the coin is released and may fall down In the meantime a projec- IOO 3o center to the open position.

through the slot and out of the case into anyv into complete engagement with the notch L at the end portion of hasp L, thus locking it in position.v The continued turning of key F in the same direction from position shown Vin Fig. 2 to that shown in Fig. 3 will not only to cause the locking-bolt C to move to its extreme outer position, but finally permit the arm or end Vportion `E4 of key-latch E to descend by virtue of spring E and a side pro jecting portion thereof, E5, Fig; 5', fall in be` I5 'hind the upward projection C4 of bolt C, and

eiectually prevent the bolt from sliding backwardly from the locked position shown in Fig.

3. In unlocking the key is inserted'and turned in the opposite direction, (indicated by Vzo the arrows,( the key-latch being first lifted psitiongindieated by the broken lines'hthe key-latch and the safety-detent Will be free under the pressure of springs E and H t0 assume the positions shown in Fig. l, when the hasp L may be turned around on its pivotal The usual notch in the locking-bolt C in which the key operates is so limited inV Width that the key Cannot be removed after the lockingbolt is throwuback to the unlocked position, (shown 35 in Fig. 1;) but,as before stated, after the in- 'sertion of a coiuany movement of the key in the direction indicated by arrow N is transmitted first to lever E and through the coin to the end H2 of the detenta-arm, which is 4o forced away from the -Wall of the slot, and

thus releases the detent from the lockingbolli."v A i I claim as my inventionl `1. In a coin-controlled lock, a case having a hasp mounted thereon, a hasp locking-bolt mounted Within the case, a detent mounted within the caseV and adapted to engage the bolt and prevent it engaging the hasp, and a lever operated by a key adapted to operate the 5o detent and release the locking-bolt through the medium of a coin, substantially as hereinbefore stated. l

2. vIn a coin-controlled lock, a case having ahasp mounted thereon, a locking-bolt mount- 5 5 ed within the caseand adapted to engage the gaging the hasp, and also vserving as la stop for a coin, a lever Within the caseand operated by a key and adapted to operate the detent through the medium of a coin within the case, whereby the locking-bolt is released and is adapted to be operated by the key into lock# ing engagement with the hasp, substantially as hereinbefore shown and described.

3.' The combination with a casing and grip# arm., of a bolt arranged to lock the grip-arm, coin-actuated mechanism and key-actuated mechanism having independent operative re lation with the bolt, and means for operatively connecting said mechanisms through the medium of a coin, substantially as de scribed.

4. The combination with a casing and griparm, of a bolt arranged to lock the grip-arm, coin-actuated mechanism and key-actuated mechanism having independent operative relation with the bolt, means for operatively connecting said mechanisms through the medium of a coin, and means for preventing the withdrawal of the key before the establishment of such operative connection, substane tially as described.

5. The combination of a casing, a grip-arm adapted to engage and hold a bicycle, a bolt arranged in the casing and adapted to be moved into locking engagement with the griparm, a dog arranged to hold said bolt against movement and adapted to be moved out of engagement with the bolt by the turning of the key, and a coin-controlled dog ,also arranged to hold said bolt against movement and actuated rby said key-actuated dog to release said bolt, substantially as set forth.

6. The combination of a casing having a coin-chute, a bolt arranged in the casing and adapted, when'released, to be moved by a key, a dog arranged to hold the bolt against movement and having a part projecting into the coin-chute in position to be engaged bya coin inserted therein, and a part actuated by the movement of a key and adapted to engage the said coin and force the same in operative engagement With said dog to move the dog out of engagement with the bolt, substantially vas set forth.

In testimony that I claim the foregoing I have hereunto set my hand, this 29th day lof April, 1898, in the presence'of witnesses.
