COIN-CONTROLLED LOCK.

SPECIFICATION forming part of Letters Patent No. 493,209, dated March 7, 1893. Application filed September 24,1892. Serial No. 446,759- (No model.)

To all whom it may concern;

Be. it known that I, WILLIAM EGLIN, a subject of the Queen of Great Britain, residing in the city and county of Philadelphia,State 0f Pennsylvania, have invented a new and usefullmprovementinCoin-ControlledLocks, which improvement is fully set forth in the following specification and accompanying drawings.

My invention consists of a lock which requires the insertion of a coin in order to open the same, so that a room or apartment to the door of which the lock is attached maybe entered, said coin being adapted to pay for a service in said room, such as the use of a water closet therein, toilet paper &c. i

The invention embodies the construction of the lock whereby the bolt is operated by the coin which has vertical upper and lower ends, and an intermediate inclined portion, and is advanced thereagainst by the operation of the exteriorknob.

It also embodiesthe employment of means for indicating that the room is occupied, and further of means for prevention of Athe descent of a coin, should one be inserted when the room is occupied,a party having failed to notice the indicator.

It also embodies means for operating the bolt from within the room so that the occupant may open the door, and the indicator is restored toits normal or inoperative position.

Figure 1 represents a view of the interior of a lock embodying my invention. Fig. 2 represents a section on line x, Fig. 1. Fig. 3 represents a section on' line y, y, Fig. l. Figs. 4, 5, 6 and 7 represent views of portions thereof, showing different positions of parts. Fig. 8 represents a perspective view of a iinger which is employed to close the chute of the slot when the room is occupied.

Similar letters of reference indicate corresponding parts in the several figures.

Referring to the drawings: A designates the casing of a lock, the same having the bolt B, and the knob or handle O on the exterior thereof, the spindle D which carries said knob, the interior knob or handle E, the spindle F which carries the said knob E, and the chute G which is open at top and bottom, the open top forming the slot H to receive a coin.

t Secured to the spindle D and rising therefrom is the dog or arm J, and secured to the spindle F and depending therefrom is the dog or arm K.

In the side of the bolt B is a recess L, one wall M of which is oblique or inclined, and which when the bolt B is in normal position, is within the chute G, as will be seen in Fig. l, it being also noticed in said ligure that the space between the base of said incline and the side of the dog J is about equal to the diameter of the coin introduced into the chute. Near the inner end of the bolt B on the side thereof, is a shoulder N, which engages with one limb P of a lever Q, which is mounted on the casing A, and has its other limb R in engagement with a pin orstud S on arising and falling indicator or plate T., which is guidedin the casing A, and provided with pins V, which enter and are adapted to play in oblique slots in the lock casing.

W designates a spring which is secured to the casing A and the stud S for returning the plate T, and consequently the lever Q to its normal position.

X designates a spring which bears against the bolt B for returning the latter to its normal position, and Y designates a spring which bears against the dog J.

On the dog J around the spindle or axis D thereof, is a collar -Z, and adjacent thereto and below .the vertical upper portion and at the lower end of the inclined portion of the chute is a stud Z, which parts are located below the space between the dog J and inoline M, and form a temporary support for the coin. t

Within the casing, forward of the plate T is a sliding dog A whose side next to said plate has a shoulder B for engagement of the lower corner of the said plate, as shown in Fig. 7. The side of the dog opposite to the shoulder B has a hook C which is adapted to be engaged by the nose D on the hub of the dog K, said dog A having a slot E to receive the guide pin F which is securedv to the walls of the casing A, said pin sustain- K ing the spring G which bears against the dog A for returning the same and consequently the dog K and knob E, each to its normal position.

IOO

On the bolt B near the front thereof, is a shoulder Il', with which engages the dog K, whereby the bolt B may be thrown back by the proper operation of said dog K.

Projecting forwardly from the plate T, is a finger J which when the'plate T is raised, is carried into the chute G, see Fig. 5, but

whose normal position is outside ol said` chute, as will be seen in Fig. l.

The operation is as follows, the parts being in position shown in Fig. 1. A coin of a proper denomination is deposited in the slot I-I, and enters the chute G, whereby it is directed to the incline M, and it rolls down the same into the space L,where it is temporarily arrested by the collar Z and stud Z. The knob C is now turned, whereby the dog J is pressed against the coin, and the latter is pressed against the side of the boltI at the base of theincline M, by which action motion is imparted to the bolt B, which being shot back, permits the door to open. When the coin fully enters the chute G, it having cleared the collar Z and stud Z', it is no longer controlled and so drops into the chute and is directed by the same to a box or place of collection, see Fig. 4. As the bolt moves it operates the lever Q, whereby as the stud S is pressed inwardly by the limb R thereof` the plate T is raised and indicates that the room is occupied. As the plate rises, it rides on the end of the dog A', see Fig. 6, untilit clears said end, when said dog under the action of the spring G is advanced in the present case to the right, and the shoulder B engages the plate T, and holds the latter in its elevated position. The iinger J which has been carried by the plate is projected into the chute G, so as to form a barrier to the descent of a coin that may be improperly introduced into the chute, it being noticed that the position of the plate T indicates that the room is occupied, and it is useless to deposit the coin for the purpose of opening the door, as the latter is locked by the bolt which has meanwhile returned to its normal position. When the occupant of the room desires to leave the same, he turns the inner knob E, whereby the dog K presses against the shoulder H of the bolt B, and withdraws the latter, so that the door is opened. Vhen the knob is let ge, the bolt returns to its normal position, and the door may be pushed closed or shut from the outside. As the knob E is operated the nose D on the hub of the spindle F thereof is pressed against the dog A', thus moving the latter in the present case to the left, whereby the shoulder B' clears the angle or corner of the plate T, when the latter is no longer controlled by said dog A', but as it is now controlled by the spring WV, it is lowered and returned to its normal position, by which operation the linger J emerges from the chute G or sutliciently therefrom, and thus presents no obstruction to the subsequent insertion of a coin and passage of the same through the chute Jfor the purpose ot moving the bolt when the opening of the door to permit entrance into the room or apartment is desired.

It will be understood that the coin is adapted to pay for a service in the room or apartment, such as the use of a water closet therein, toilet paper &c.

The attendant of the room or owner of the business involved may operate the bolt B by means of a key which may properly reach a shoulder on the bolt, such as K through the openings or hole II in the casing.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
