PERGIVAL EVERITT, OF LONDON, ENGLAND.

COIN-OPERATED LOCK.

SPECIFICATION forming part of Letters Patent No. 374,785, dated December 13, 1887.

Application led .Tune 16, 1887. Serial No. 5241.494. (No model.)

To all whom, t may concern:

Be it known that I, PERCIVAL EVERITT, a subject of the Queen of Great Britain, and a resident of London, England, have invented certain new and useful Improvements in Coin- Operated Locks, and is applicable to water and other closets, lavatories, and the like,of which the following is a specification. l

Figure 1 represents the inside of a door of a water or other closet, and to this door I apply the devices whereby the door, which is normally locked, may be unlocked by the deposit from outside the door into a receptacle inside the door, through a suitable slit or slot made in the door,of a coin, token, or the like. Fig. 2 is a top view showing the door partly in section, and also showing a small part of a door-frame in section.

The parts not necessary to be described are omitted from the drawings.

On the inside of the doorA,I arrange alockbolt, a, and a latch-bolt, b, each of which is secured to its respective rod or bar a or b', and these bolts are shown in the position usually styled half-shot,7 and c d are bell-crank levers, one end, o', of lever c being pivoted to rod a', and one end, d', of lever d being pivoted to rod b. The other arm, c2, of lever cis slotted to receive the lower end of a link, e, which is jointed to the shorter arm of alever, f,which carries at its other extremity the coin or token receptacle j. The upper or remaining end or arm of lever d is pivoted at d' to a vertically-movable rod, g, held in a guide, h, and is provided with a pin, i, projecting backward toward the door. Thelevers are shown at about the center of their travel. Any suitable slit, k, cut through the door, with or without a chute connected to it, serves to guide into the receptacle j the coin or other token of predetermined weight and size. The weight of the coin carries down the lever f,

and the receptacle discharges its coin in the same manner as in my application, Serial No. 226,251, allowed on or about April 29, 1887, or as is usualin other devices of such character; and the devices for effecting such discharge need not therefore be here repeated.

Now, upon depositing the coin of proper size and weight in the slot 7c it passes into the u receptacle j, and by its weight carries down its longer arm (this lever being fulcrumed at f.) This movement lifts link e, and bythe means of pine thereonthe arm c2 of lever c is raised, and thereby its other arm, c', draws backward bar a and its bolt a. Vhen the weight of the coin has carried lever f low enough to bear upon the pin i on the slide-rod g, this movement of rod g actuates the arm dL of lever d,and either draws b ack or permits a person on the outside ofthe door, by turning the ordinary latch knob orhandle, to open the door. Vhen the coin, after the receptacle has descended,has dropped ont of such receptacle, the lever f, being thus lightened, goes back t'o its normal position, and the bolt a also is forced back to a position which again locks the door, and which again requires the deposit of a proper coin or token before it `can be opened.

I claim-- The combination,with a door havingaeoinreceiving opening, of a coin receiving and discharging boX, its Supporting-lever, the link e, levers c d, rods or bars a a b b', and the sliderod g, all substantially as and for the purpose set forth.

Signed at New York city, in the county of New York and State of New York, this 13th day ofJune, A. D. 1887.
