COIN-CONTRCLLED LOCK.

To all whom t may concern.'

'Be it known that l, Geenen G. F. Bos' ings.

The object of this invention is to provide an improved coin-controlled lock for cheek rooms, toilet rooms, telephone booths and 'thelike The nature of the invention will be understood from the accompanying drawings and the following description and elaims.

'In 4the drawings, Figure 1 is an elevation of the front edge of the door and lock thereon, the upper and lower parts of the door being broken away. Fig. 2 is the outside elevation of the lock and the portion of the door attached thereto. Fig 3 is a sectitm on the line 3-3 of Fig. 2 but on a larger scale showing the dilferent positions of the coin by dotted lines, and the partsl being shown in their operative. position. Fig. 4 isfa section on the line ljl- 4 of Fig. A 1 through the loek but on an enlarged scale7 and showing the lock in normal condition. Fig. 5 is the same with the means for indicating and also controlling the eoin slotbeing omitted. Fig. (3 is a section on the line Fig. 7 a section on the line 7*7 of. Fig. (3, showing the coin in the locking position. Fig. S is the saine as Fig'. 7 with the knob actuated and the boltwilhdrawn. 'Fig-@ds a horizontal section on the line`9--9 of Fig. 1, through the lock and` a portion of the door and showing the parts in normal position. Fig. l0 is the same as the central part of Fig. 7 with the parts in position after vthe door has been closed or locked and the coin discliarged. F 11 is a section on the line 11--11 of Fig. t).

In detail, there is shown in the drawings a door 10 to which. there is secured a leek case 11 and t2 is the outside knob which is secured on theknob shaft- 13 by a screw 14.

as shown in Fig. 3. The outer end of the knob shaft 13 has a tubular opening 15. The central part of the knob shaft has normally a vertifal slot 1G through it and the inner end of the knob shaft is likewise tubular and internally threaded to hold the Specication of Letters Patent.

adjusting screw 17. The knob shaft has a shoulder 18 which engages the inner surface outside of the easing so as to prevent the outward withdrawal of said knob shaft, and the screw 14- -has its head vlocated in said tubular opening 15, and the body of the screw passes through a reduced opening in the eXtreme outer end of the knob shaft, whereby it is impossible for anyone to re' move the knob from the outside. ln order to operate the screw 14, the screw-driver is inserted through the door and the knob.

shaft freni the inside before the adjusting screw 17 is in place and before the plug 20 hasbeen inserted in the opening through the door which leads from the inner surface of the door through to a chamber 21 therein. There is an enlargement of the knob shaft 22 which tits against the inner surface of the inner wall of the casing. The extreme inner end of the knob shaft is externally threaded for a nut 23 which lies in the recess 21 of the door. Therefore, the knob shaft cannot be moved in either direction and it is firmly held in place in the walls of the casing, and the knob shaft also holds the walls of the casing in place and suitably spaced apart. The width of the coin .slot 16 in the knob shaft is modified by the screw 17 to suit coins of any denomination. On the inner half of said knob shaft within the easing there is a sleeve or tumbler 25 which has longitudinal slots 2G on the opposite sides of it to correspond and register with the coin slot 1G in the knob shaft. Said tumbler and knob shaft have intkpemlent rotary movement limited 4by the length of. the Aslot 126, see Fig. 10, through which the arm 27 from the knob shaft extends and to which the spring 2S is connected, said spring extending downward and being secured at 29 to the inner wall of the casing. The function of the spring 2S is to returnthe parts to their iormal position after they have been operated.

There is a plate 31 secured to the inner wall of the casing and extending toward the outer Wall. To said plate 31 a counter 32 .is secured which projects through the opening in the end Wall of the casing and there discloses numerals indicating the number of times the leek has been operated.Y The counter has a shaft 33 which is actuated by movement of the arm 34.

The tumbler 25 has 4a bolt-withdrawing casing 11 and 111. That portion 45 inside arm '35 projecting radially therefrom, as shown in Fig. 5, with one surface curved in position to engage the pin 3G on the bolt 37 and withdraw it when the knob 12 is turned. ,lVhen the spring 23 returns the parts to their normal position the arui 35 engages the shoulder 38 of the bolt and throws it into locking position. The bolt is guided by the usual opening in the end wall of` the casing` and also by lugs or projections 39 and 4() on the inner wall of the easing, see Fig. The bolt is held against the inner wall ot' the casing by the arm The return iiioveiiien't of the arm 35 is limited by the stop lug 30 which extends from the inner wall of the casing, see F ig. 5.

In the outer wall ofthe casing, near the upper end, there is a coin Islot 40, see Fig. 3, through which va coin 41 may be inserted. When said coin is inserted it extends through a slot 42 in a plate 43 which serves to close and open said slot as well as to indicate when it is closedor opened. Normally said slot in the plate 43 coincides with the slot 40 where` by the coin can be inserted.. The coin moves between two parallel guide plates 44 which extend outwardly from the inner surface of the inner wall of the casing, as shown in Fig. 5, and extend down to a point lower than the bolt 37, but wherethey extend over the bolt 37 they extend over so as not to interfere with the movement of the bolt; This coin chute forms vert-ical passageway for the coin, which registers with the coin slots 26 and 1G in the tumbler 25 vand the enlarged portion of the knob shaft.

The inner knob shaft 140 is located somewhat above and to thev right of the outer knob shaft 13. Said shaft 140 has a squared vouter end fitting into a corresponding slot in the inner knob 141 which is held on said shaft by a sci-ew 142 against the shoulder in the` outer end of the tube 143 through the center of .said knob shaft, as shown in Fig. 11. This shaft has rounded portions 144 thereon to form bearings in the walls of the the casing is square in cross section and/near the rear wall `111 of the casingA a finger 46 projects in a downward and-inward direc tionto engage a lug. or projection 47 on the inner end of the bolt 37, and will,` when thel inner knob is turned', cause the withdrawal Thatend of the shaft near the of the bolt. -out'er wall of the casing l1 is slotted to receive and hold, by means of the screw 48, a

piece ofsheet meta-l 49 similar in shape tov the ward of a key. This strip is adapted toy clear the wallsof the casing andhas a projection 50 concentric with the tube 143 and projecting even with thev end thereof, which projection serves as a pivot for the key which p thc casingl il, whereby the bolt may be withmay be inserted through the key-hole 51 in drawn without inserting' a coin iu the Slot- 40. The ward-like strip 49 serves to engage H and move the plate 43 back to its normal position and open the coin slot 40 whenlthe inner knob is tui-ned. The plate 43 is pivotally connected by the link 55 with'the arm 34 on the shaft of the counter 32. plate 43 is nioved by the movement of the outer and inner knob, the caused to register.

A door :'iti at the lower front portion of the casing has downwardly projeeting lugs 58 on tliei'eai'side which will engage: a rim of th'c casing, and by means ofa lock GOvronthe upper and iinieigiside of said door the defer iii-ay be held in place in the front casing-1,1 and will lie flush with said casing.vr This counter will be Thus, as the door affords means, whereby the coins which and fall through the coin chute into the coin slot 16 of the knob shaft 13 where it will be held against an edge on the lower side of said coin slot 16, as shown in Fig. 7. When the outer knob 12 listurned,the edges of said coin-slot will pinch or'engage the coin, and by turning'the knob'fa-rther the coin will en gage the edges of the slots through the tumbler'25 and the plate43 and-will cause them to turn. Vthen the knob 12"l is turned to its extreme position the'plate 43I will close the coin' slot and throw the lever 34( of ,the counter to the right, While the bwyltvi'thdrawing arm 35 0n the tumbler 2553 vill cause the withdrawal of the bolt and allow the'door to be opened. Upon releasing the knob the spi-i g 28 will cause the return of the bolt 37, the knob shaftand tumbler to their normal posit-ions and the coin will drop through the slot in the tuinbler25 and' into the lower portion rof the lock case at the rear of the door 56. But the plate 43 will not be returned to its normal position and will keep the coin slot 40 closedfuntil the rear knob is turned. This action will push the plate 43 t0 its normal position-and open the slot 40 and will give the final or registering stroke to the arm 34 of the counterl and cause'it to register. I
