To all whom it may concern?.

admission fee deposited in the lock in the.

shape of ai coin will render the same operable to the person depositing the coin.

A 'further objectA of the invention is to provide a lock of simple and urable con# struction which' cannotbe easily tampered with'and opened without iirst depositingv a coin of predetermined size and value there- .in, in the -manner provided for by thelconstruction of said lock. y

accomplish the objects 'of the invention by the mechanism illustratedin the accompanying drawing, in whiche-` Figure l is an edgeeview -of a portion of a= door bearing my improved lock. Fig. 2 is a vertical section of my improved lock separate from .the door, on the line 2 2 of Fig. 3. lock with the inner plate of the case or housing removed, the view showing the bolt and its associated parts in the locked positionof the bolt. Fig. 4 is a like View showing the bolt in its drawn or unlocked position. Fig. is a view of the bolt similar to that shown in Figs. 3 and 4 as it appears -when removed from the casing and other parts of the lock. Fig. G is atop plan view of the bolt shown in Fig. 5, and Figg' is a section of the bolt on the line 7-7 of Figs. 5. and 6.

Like characters of reference indicate like parts throughout the 'several views of the drawing.

'8 represents a door of. any 'usual and suitable construction to the room, booth or receptacle to be locked, and my improved lock is shown here as a rim l'ock which is secured to the inner side of the door by means sheet-metal casing 10 which comprises sides A Fig. 3 is a front inside view of the and' ends 11 at right angles te and preferably integral with.aJ plate 12. The sides and en ds 11 have inwardly projecting lugs 13 which afford means .for the'attachmcnt pf le; plate 14 .which closes the casing ofthe oc l 16 represents the'bolt, the body of which against the' inner side of the plate 12. One end of the bolt is reduced in width to form a part 17 which projects through a suitable opening in the side ll-and this extended -portion is provided with a hand-knob 1S which is accessible to a personen the inner side of the door for moving the bolt. The opposite end of the bolt is also reduced iu width to form shoulders to arrest the movement of' the bolt in that direction. This portion is thickened however in the opposite direction to form the part 19 which passes through the adjacent side ,11 of the casing and is the part' of the bolt which engages a striking plate (not shown) if usual co'ustruction on they frame of the door and locks against said striking )late in the usual manner. To cause' the inward ldirection automatically by the closing of the door thisv thickened vportion 19 is rbeveled as shown at 20.

The. difference in thickness between 'the' body 16 of the lock and the end 1 9-l forms a shoulder 21, and bearing against th'e shoulder 21 is the upperv bent end 22 of a lever 23. A shaftl 24 is mounted in the tivo plates 12 and 14 of the casing and the lever 23 is mounted in a fixed manner on said shaft so as to be oscillated by a rocking movement of the shaft. The diameter of the shaft 24 for that portion ofthe vshaft which lies between the plates .l2 and 14 islarger than the extensions of the shaft in veither direction whereby shoulders are formed to prevent longitudinal movement of the shaft. This sha-ft 24 extends through the door 8 and is provided with a handle 26 on the outside of the door for the manual rocking of the shaft.

The bent end 22 of thelever 23 is attached ported by the plate-12 of the casing.4 The edge ,of the plate 29 acts as a guide and 'is flat and comparatively thin andfrests' oltto be shot in ansupport for the lower end of the lever 23' and the lug 28 acts as a stop to limit. the outward swing of said lower end and consequent movenifent'iiofftflie lever-.23 and handle 26.

Supported by the' upperrend4 Y11 'of the lock-casing is a coin chute 30 the lower end of vWhlc'h 'discharges Within the casing above the bolt 16. The chute extendsobliquely out through the; casing and through the door'9' and is indicated and protectedby means of 'a suitable metal esoutcheon 31 wnichjwilllbe slottedand 'may be provided with ya suitable legend directing the deposit of a'coin.

therein. Mounted on the bolt 16 directly under the fdischarge vend of4 the' chute 30,v lwhen the bolt is shot in its locked position is a continuation of the chute, and the upper end of thepartis expanded into a unnelj'shape to catch and insure the delivery of a coinfromthe chute 30 to the extension 33. An angle plate is secured -to the plate 12 of the lock-casing and the upper horizontal member ofthe 'angle plate pro- I t 26 I,on the rock shaft 24. '..Contact between 'jects across ythe discharge end of thechute 'the lever and coin' whenaboye situated is v notch .allows [the upper endl of the S5.'

The inward move-- ment ofI the bolt v16 is ,arrested by Contact of shoulders 40 with the sides l11 of the casing, andv the person manipiilating the handlev 26. ywill almosty invariably release vthe handle vuponA theV arrest ot' bolt 16 by this Contact ofthe shoulders 40' soft-hat, if the coin has not been previously released it will receptacle 41 there plaoed. to receive portion42 ofthe s1de'11 ot the casing will` be removable to ff-lithi.Y

`acces'slto the coin receptacle 41 whereby' the latter may be taken from the casing to permit the removalv of .the yaccumulation of coins therein. Thisremovable plate 42 iv'ill have a lower lug 43" to engage the inner side of the part 1'1to prevent the removal of platen-42, @nd secured to the inner side of the plate 42. 1s a lock 44 enough'itocause the coin tov pass the end of 4,16 to receive theward having a bolt. 45 whichI isV .shot upwardly against the inner side of part 11 lto prevent the removal of the portion 425 while the bolt of lock 44 is in its outer position.

In some instances it is desirable to pro vide means for retracting the-bolt 16 to unlock the door without depositing a coin in theslot as above described. This ocours,":t'or example, where the lock is used on toilet room doors and it is necessaryfor a porter 75, or attendant to enter the toilet room fre-7 quently for'rthe. purposeof cleaning the interior of the room. This contingency l provide for by forming a notch '46 in th bolt of a key is' key 47 is mountedv v not to b'e removed. efrom and 'has its A stem extending out .ti ough the door 8 and squared to fit the socket of areinovable extension 4'carried by the personl who desires -to ventertheroom. This auxiliary-key may be lomittedif desired. i y

The'foperation of my devicey Ais lastollows.- lVhenf'the door is locked. and itis desired to unlock same a. coin of the designated size 'is introduced into the chute 3() `and failing bygrayity is. arrested by the shelf 35 in the path'ot the upper end of lever 23. The person'depositing the coin grasps thefhandle 26in'1mediately after" making his deposit 95 and by means of the handle rocks the shaft 24 to inovethe upper end of lever 23 against the coin and by continued pressure shoots the bolt 16 inwardly of the lockthereby unlocking the door. lWhen 'the person on the inner side of the locked door desires to f'unlockthe doorfhe is enabled to do `so by vgraspingthe knob-18'and moving the bolt back by a proper pressure. y

Having thus fully describedmy inven- 'los ltion what I claim as new and wishto secure by'Letters Patentof the United States.r is* 1f; In a coin-controlled lock, the. combina-v .tionof a' casi'ng,fa coin clnitedischarging Iwithin said/casing, a bolt under the dis- H0 charge end` of the chute having a' shoulder and also a chute extension which latter alines with the first chute when the bolt in its outer shot position, means including a stopto expose a coin at the lower end of saidchute extension and an arm-adapted to be moved 'to-shoot the bolt inwardly by con- -=`t`act with saidv exposed coin and outwardly by Contact with the shoulder on the bolt.
