rado', have'invented new and useful Im'- provements in Locks, of which the following is a specification. This invention relates to locks and more particularly to coin controlled locks.

'O ne 'of' the principal objects of the invention is the-provision of 'allock' of this character, ha ving 'meansj whereby the key may be withdrawnfromthe lock only by'a coin being used of the proper denomination; A further -"object of the invention is the provision ofa combined key and coin controlled mechanism for securing" the lock I will be understood that this type of l oc'k is against operation until a coin of the proper denomination is used in connection with the key, so as toprevent the release of the locking mechanism and the locking of the look. It

especially adapted for use in connection with lockers and'the like in public places-where. a' person can deposit any articles and, by using-a coin of the. proper denomination, can operate the ,lock'to'lock the cupboard or locker and thenfobtain the key for opening the same when itf is desired to remove the e articles. The operation of unlocking the lock automatically:- secures the same in unlockedposition and holds the "key against removal until another'ccin is deposited.

Further objects of *the invention-will 'api pear as the following spe'cificdescription is read in connection with the accompanying this appliv 3 ing end is; made somewhat wider than the drawings, which form a part of cation, and in which Figu lines in all the figures indicating the door.-. Fig. 2' is atop plan'yiew. Fig-.;is-a vertical sectional View showing .the keyin.

I Fig. 7 is a perspective view the casing is mounted the ordinary bolt 4 and tumbler controllers 5. The lock has a cylinder extension 6 which projects through re 1 is a rear elevation of the: device shown attached to a door,'the'-dot' and dash the front of the door and mounted in the cylinder is a key-plunger 7 slotted at 8 to receive a key 9. I

An auxiliary casing 10-T-is mounted -.upon the cylinder and'connectedto the front plate .s ecificauo i 6. fl iatentf Patented May 28,1912. App 1ieation filed Augustfi, 1911. iseriai No.'643-,1'0 2.

and has secured therein a spring 11 having a cam outer face 12 adapted tobe engaged by the key, for. depressing thespring. The

spring passes through a slot 13 in the cylinder 6 andfis adapted toenter the slot 8 when the key 9 'is removed therefrom, so as to hold the plunger in position against turning untilthe key is inserted, which action depressesthe spin and permits rotation of the .plunger and t eretraction ofthe-bolt 4.

' I The casing l'O is providedwith an extension '14 which is raised from -.th'e plate 2 and is of such a width as to permit one leg 15 ofa U-shaped locking member 16to slide therein. The leg 15 of the locking member has its lower end reduced, as shown at 17, to

passthrough' an opening 18 in the casing 6 and enter an arcuate slot 19 formed in the plunger and having shoulders 20 at theends thereof. The opposite'end of the locking member-16 is indicated; at 21 and lies upon' the inside of the casin 3 and is parallel with the leg 15', the lock ng member passing "through a slot 22 in the plate' 2 which is.

coincident with the channel in" the extension 14 ofthe casing 10.

' The lower end of'the leg 21 is provided with an arcuate linger 23 against which the coinfindicated' at 2a, is adapted to rest.

When'i'n' operative position the coin. is positioned-between the finger 2.3 and the proje'cting end 25 of the. key 9.- This projectordinaryikeys of this typie sothat when the keyfis 'turned in the-lock the length of the sl ot 19 it will raise the coin a sutficient disanally forced downwardly by a leaf spring 26 which is secured to the front plate and lies over the top or connecting portion of the lock member.

When the key is placed in the lock and displaces the spring 12 the plunger 7 may be turned to the position shown in the Figs. 3 and 5 where it will abut one end of a stop 27 carried by the cylinder 6. In this position the leg 15 of the locking member will have its reduced end 17 entered in the socket or channel 18 so that the plunger is positively prevented from turning, except for a shortdistance. When a coin is inserted in" the deposit chute 28 it passes through t he same and rests upon thefiatside of the key' extension 25 and is held in such position by the finger 23 which it lies beneath. U

' the coin and consequently the looking 'di ib" 16 andthus release its reduced end from-the 4:, where it-is released'from' the flange '29.

When; the key is in this position it is engaged with the opposite-endof the stop 27 and theguidingor positioned ward. isreleased from the flange 29 and the key in aline ment with the "slot 3- 1, formed in the flange 29.1 After the keyrhas' been turned around so as to aline with the-slot 31 and removed from-the plunger, the-coin drops into ya -coin chute 32. This chute 32 is carried by a cas- 1 fing -33Zwhich'cou-ers the locking member 16 andwthelremaindjer of the lock and. is pro vided with a door 34 in its bottom which closes the inon'eyvpocket -35 therein and is provided with aseparate lock 36 by which "1 the-.dooris fastenedl This lock 36 is con- .trolled only by the pass key which is carried by the owner-or agent of the person owning the lockers.

Having thus described the invention, what I claimsa's new is 11111 combination, a look having a bolt, and a slotted key plunger, means for se curing the key plunger against turning in a direction to project the bolt, means for holding afcoin, and a key" for throwing the securing means to inoperative position through the intermediary of a' coin and for projecting the bolt said key directly engag- I ing the coin.

V lock including albeit, a key for projecting and retracting. said bolt, means to secure 'the'bolt against projection, and an Opera'- tiye connection between the key and the-.se
