` To all 'whom it may concern.:

Be 1t lino-wn that ne, Vi'innis FARNS- Wonrn and VILLIAM H. linnn, both citizens of the United States, residing at Petaluma, in the county of Sonoma. and State of California, 'have invented nei' and useful Iniprovements in Coin-Controlled Locks, of which the following is a specification.

r)This invention relate-.fs to locks, und pertains especially to a lock Controlled hy :i slug", coin, or other token.

The object. of the invention is to provide n simple, cheap, practical and elieient look Whiohcan only, be opened upon the depositing of a proper coin or token.

The invention consists of the parts and the construction and combination cf parts as hereinafter more fully deserilied and claimed, having reference to the accompanyin'r drawings, in whiehy 'igure 'i is a front elevation of the invention with the front cover plate broken away and with the lock controlling mechanism in' normal lool-:ed position, with the key in place, the key being shown in section. Fig. 2 is :1 similar view with the parts thrown forward in position t0 retract. the bolt and allow the lief." to b'.- removed. Fig. Bis a detail of the key controlling mechanism lwith the in position ready to unlock the lock the second time. Fig. 4 shows the parts the momentthe coin is dropped and the key retaining means returning to initial position. Fig. is a. vertical section through the mechanism. Fig. tl represents a suitable key.

In the embodiment of the invention n'e have applied it in conjunction with on ordinary spring lock A, of Fig. havingthe usual spring projected holt f2, Fig. l, and the moh shank provided with n keyhole into which a lint key 5 is inserted to operate the holt in the usuel fashion.

Carried by the knob shank or actuating Shrink l is n radial arm 5 which turns when the ltev turns. The backward inotion ot the nrxn 5 is limited by a suitable stop (i, and this nrm Curries a lng 7 adapted to en nge sneeess'ively the shoulders S--l on the sliding plate lo, on the successive oscillations of the nrxn due to the turning ot' the key. r `he plaie l0 is slotted lengthwise, :is shown :it 1l, und fiile-rinus in this Slot on a pin 12 carried bj.' n tired pnrt of the containing means, here represented by the ense 13. Pivoted on the rear end of the sliding and rocking place l0 is n latch member 14 `.which is adapted, when the plate l0 thrown hack- -n ard under the impulse of the Spring 15, t0`

engage `oehind n fixed Stop 1G. `Whenever the latch 14 is engaged behind the fixed stop 16, as shown in Fig. it is impossible to more. the bnr l0 forward; and, in fact, it is impossible to remore the hey, becauselthe key-4 is provided with a slot '-l adapted to receive the lower edge of the sliding plate l0 when the parts are in the position Shown in Fig. l. rhe hitch 14 is fiile-,ruined on bnr 10, as shown at 17, the forward end beingheavier so that it- Will naturally dropdown into the path of the stop 16. The rear end of the hitch 14 has :i curved horn '18, or is otherwise suitably fashioned to forni n sent for :i Coin or other token, ns represented nt 19, when the parts are in the position shown in Fig. 2. v

In practice, assuming that the parts are in the position ehoivn in Fig. l and the hey -2 inserted into the keyhole, in order to operate the lool; a Coin 19 is dropped into the chute 20 and rolls down until it strikes the top of the rear end of the hitch i4, :is Shown in Fig. l. and encounters the reni' vertical wall 21 of the chute 30. The weight of the coin is sutiieient to tip up the hitch 14 into the dotted line position shown in Fig. l. This releases the hitch from interference with the fixed stop lo. .so that the key can be turned in the direction of the arrow. Fig. 2, and to bring the pnrts into the position shown in Fig. 2; this forward n'lovenient. of the bnr 10 being accomplished by the engagement of the lng 7 with the front shoulder S on bnr l0. This tnt-ningr of the` hey is snlhrient hoth to retract the lnteh holt. so that the door or other sealed part may he opened, and :it the saine time it will allow the coin 19 to drop down n step into the position Shown in Fig. the shape of the horn 1S, and the dis tnnce between it :ind the ref ir rigid Wall Q1 of the chute. however, being insnllieient t0 let the coin full further on this lil-st movement of the key. The key nnry than be removed. ln this removal of thekey, the ordinary springlnot. here Shown) in connection .with the hitch holt 2 projects the bolt 2 forward again, so that. the door will Snap closed, and also returns the arm 5 into the po itiou shown in Fig. 3. ln lhi return movement of the arm I the har It) toes not nove. exfept tw' its front etul iS :tt-tell on :eligfhtliY nml liiietl hv the action of the spring' l?, on the lug l2 on har ltl: this lil'ting aetion Se! ving to hringr the lug T on the arm 5 into engagement with the serontl shoulder S) on hz Hi. The ke;v i# then reniovwl.

.it this point it may he statetl that this locking leviee is particulari)- intenslell for use in cloak x'ooinsarul other places where eaeh n'artlrohe or 11 l'etv tleposit hox is provifletl with a spel'ial lock :unl l\'e v. :unl each guest or euStonu-r mav have an individual .vartlrohe or hox antl look out for .iria on'n tl'iings or valuahles. all that i` nerefsary for him to lo heine` to lt-posit a vein :incl turn the key once to open the hox to put in his thing.-;, remove the ke v :uni elo.-e the hox. Then when he \vi he.\f to take his things out again he rein-ert hi A kev into the ke \hole; the coin previamsly tlepositeil still 'being in the position honn in l"ir 'f :unl the ('oiu showing tlntuufh a transparency or window 23 in the easingl which housethe meehanism.

ln unloekinj,r this lock the second time, after insertingr the kev. the har It). h v reason ot the engagenant of the lug: 't' with the rear shollhler 5), is thrown forward a :'tep farther than it tra# the tiret time. So as to allow the eoiu to tlrop (lon'n into the position hotvn in Fig. 4, and tht-nee to he caught into a suit ahle hox or reeeilnaele 2l. Fig. ln this seeontl unlockingn inoreinentthe ha? 1t) thrust So l'ar forward that its front hereletl nose '5 engages a tixetl piu 26 so as to press the front eml ot' the har 1') tlownwarti. roeking it on its pivot 12 and releaeinlg1r the har from the pin or lugr on .irm 5, as shown in Fig. 4. Thereupon the sprin,"r t5 acts` on the har l() to throw it haek until the forwartl shoulder S is intereeptetl hf.' the lug' I. lh leasing the turuinzgr pressure on the key allows the holt to again he projeetetl outward. anti the arm 5 :unl the .wreral parts te: he returned to initial position. represented in Fig. l. :nul with the non-h -t in the ktv caught h v the lower projeeting eclge portion t of the har l0. ln this po.-.ition the key cannot he removetl until :t fresh ruin :d heen lepositecl :intl the parts turned aa shown in Figs. :l :nul 2l.

The housing:l lil may take an)y suitahle form, and may he attaehetl to the door or other thing to whit-h it is applieahle. in any Suitable manner.

From the foregoing it is seen that dropping the, coin into the slot releases the lateh 14 and allows the loot to be opened alul the key to he removed. The coin holds the latch in elevated posit ion so that the lomean lai unloekerl once more alter the key is inserted On the release, of the coin from the latch thev l key is prevented from Withfl rau'al, and the lock cannot he again actuated until the latch is releaaetl hy a. Jfresh coin.

lt. is manifest that. this littlewcleviee is applieahle to --toek ha'ks. or itn|a \r he matle 7U the invention isnot. limited to any specific forni or arrangunent of parts, except in so far as such limitationsl or their inechanieal equivalents' are specified in the claims.
