To all whom it may concern Be it known that I, AMos A. lVYoKorr,

a citizen of the United States, residing at l v tion with storage spaces, lockers, safetydeposit vaults, and the like, which are customarily rented for occupancy for a iiXed rate perrdiem, or other period of time.

Among other desirable objects, attained,

my present invention is designed to provide a lock which, when unlocked, will prevent.

withdrawal of a key therefrom and which clan be locked only after a coin has been ydeposited therein, whereupon the key may be withdrawn and retained as a check by thev user.

My invention also comprehends the element of time so that, if the goods or articles are left in the locker beyond Va predetermined period for which the lock may be set,

it will be necessary to deposit one or moreadditional coins, depending upon the length of time that the lock has been locked, before it can be unlocked again. Y

Another object is to provide a mechanism which will become operative, only after the maximum'period of time for which the lock is designed has expired, to positively prevent unlocking of the lock bv the key of the user, with the result that the user mustl Further obiects and many of the attendant advantages of this invention will bev readily apparent to `those skilled in the art as the same is better understood by reference to the following description when considered in connection with the accompany-` ing drawings illustrating one preferred embodiment thereof.

Specification. of Letters Patent. Patented Sept, 315, 19141:, Application filed August 7, 1913. Serial No. 783,519.

Referring to the drawings-'Figure 1 is a front view of a lock embodying my invention; Fig. 2. is a transverse sectional view on the line 2-2 of Fig. 1; Fig. 3 is a -longitudinal sectional View on the line of Figs. 1 and 4; Fig. 4 is a rear view of the lock showing the locking bolt .in unlocked position; Fig. 5 is a similar view showing the position of the parts when the locking bolt is in locked position; Fig. 6 is a sec tional view taken on the` line 6-6 of Fig. v4; Fig. 7 is a view taken on the line 7-7 of Fig. 4; Fig. 8 is a sectional View taken on the line 8--8 of Fig. 4; Fig. 9 is a detail perspective view of the two-piece slide and Fig. 10 is a detail View showing one of the 'cams for withdrawing the coin support from operative position. v

On the drawings reference character 11 indicates the lock body or frame provided at its `edges with rearwardly projecting iianges 12 and 13 having slots formed therein to support and guide the locking bolt 14.

This bolt is provided, as shown in dotted lines in Fig. 4, on its front face with a coin groove 15 which, when the bolt is in unlocked position, is disposed in alinement with the lower end of a coin slot formed by a two-part slide, the parts of which are indicated in Fig. 9 by reference characters 17 and 18, slidably secured to the frame -11 by overlying. flanges of rollers 19 mounted on screws 21, or other preferred fastening means. The frame is provided'adjacent its top with a pair of coin-receiving apertures 22 and 23 disposed in alinement with the coin slots 16 and 24, respectively. of the two- -part slide.

The locking bolt 14 is provided at its upper edge with a recess 25 rounded at one side as indicated at 26, this recess being adapted to receive the downwardly projecting finger 27 of the slide and, when the parts are in unlocked position as shown in Fig. 4, `this linger precludes locking movcment of the bolt, the finger being held in engagement in this recess by means of a leaf spring 2S ixed to the frame and pressing against a pin 29 projecting rearwardly from the post 31 of the lower part of the slide. When the parts are in unlocked positionf as shown, a bar or plate 32 formed across the front of the coin slot 24 covers the coin-re- 22. A similar plate o r bar 33 over the coin ceiving aperture 23 so that a coin can be deposited in the lock only through the aperture slot 16 serves to close the opening 22 when the locking bolt is in locked position so that the slide is raised to the positionshown in Fig. 5. The slide is made in two vpartsl in order that the locking finger may not be lifted out of engagement with the bolt by inserting a knife or other instrument through the coin-receiving - apertures 22 or 23 from the outside of the lock, This construction therefore obviates tampering with the lock.

A key-cylinder 34 mounted in the casing 35, bothI of which may be of well known or coin resting upon the casing 35 in the coinl groove of the locking bolt and, whenl the key-cylinder is turned, through the lnstrumentality of a key 39 inserted thereln, to

swing the arm 36 from the position shown' in Fig. 4 to that shown in Fig. 5, the coin acting upon the linger raises the slide to release the nger-from the recess 25, thereby permitting the bolt to .be moved to locked position. When the parts are in this locked position the aperture 22 is closed by the bar 33 andthe aperture 23 is opened to permit the insertion of a coin therein which will drop through the coin groove 24 and through the groovevl in the locking bolt alined therewith into a coin chute'beneath the bolt, which will be later described.

Beneath the locking bolt aA latch 41 is slidably mounted in suitable guideways formed in a bracket 42 attached to the main frame and this latch is normally urged into engagement withthe bolt by a coiled expansion spring 43 interposed between the lower guideway and a collar 44 on the latch. When the bolt is in unlocked position` as shown in Fig. 4 the upper end of the latch engages iny a shallow notch 45 to yieldingly retain the locking bolt in unlocked position and prevent rattling of the same. When the bolt is inl locked position .as shown in Fig. 5 the upper end of the latch engages in a notch 46 formed in the lower edge of the locking bolt and prevents-movement of the bolt tonnlocked position. Itwill be manifest, however, from an ins ection of Fig. 5 that when the bolt is in ockedy position la slight initial movement toward unlocked position `is permitted before the inner wall ofthe notch 46 abuts against the latch. This initial unlocking movement is utilized to release the latch by means of releasev mechanism vwhich will now be described.

A bell-crank lever 47 pivotally mounted at 48 has one arm 49 thereof attached at 51 to the lower end of the latch 41. The other arm 52 of the lever projects upwardly adjacent to one side of the coi-n chute 53 and, in effect, forms a portion of` one side wall of said chute. A second bell-crank le'ver 54 pivoted at 55 has one-arm 56 disposed opposite to the arm 52, the arm 56 also formingv a portion of one sidewall of the coin chute 53. The other arm 57 of the bell-.crank lever 54 is urged into engagement with the surface 59 which permits the bell-crank lever 54 to assume the position shown in Fig. 5 when the bolt is in locked position'. Initial unlocking movement of the holt will rock 'the bell-crank lever so that the arm 56 through the lintermediary of a coin in the chute will actuate the arm 52 and thereby cause the latch 41 to be withdrawn to release the bolt. It will thus be manifest that theY lock can be locked through the intermediary of a coin inserted through the aperture 22 and that when the bolt moves to locked position the coin will drop from the groove in lthe locking bolt into the coin chute and so long as the' coin is sustained in position between lthe arms 52 and 56 of the bellcraik levers 47- and 54, respectively, the lock may be unlocked without any more coins.- Y

As is well known, it is customary in the checking of articles to charge for the length of time that the articles are checked, the

' usual charge in railwaystations, -or similar places, being ten cents for each twenty-four hours. 'When lockers equipped with my invention are used in lieu of the ordinary checking system, it is obviously essential that the storage charges likewise be proportional to the length of time that the articles are stored. I have, therefore, pr0- vided mechanism which will preclude undepositing locking of the lock and the release of the ars ticles stored until'coins proportional in number to the time that the articles have been stored are deposited in the lock." Wit-h this' end in view, the coinchute is provided on its rea"face with an elongated longitudinally, extendingslot; and a head 61, Figs. 4,.

5 and 8, pivotally mounted at-62 upon a rev ciprocal rack-bar 63, is provided with apin 64 projecting through said slot into the chute in position to support the coins therein.A A coiled expansion spring 6 5, bearing at its lower end against a rack-bar guide 66 and at its upper end against a shoulder 67 on the bar normally sustainsthe coin lsupport in 'm moet the elevated position shown in Figs. 4 and 5 to support a coin between the bell- cranklever arms 52 and 56.

Let us assume that the lock is designed to give the user a twenty-four hour period of service for a coin of predetermined denomination. If the lock should be left in locked position for more than twenty-four hours a second coin should be deposited before the lock can be unlocked and the goods released and an additional coin should be deposited for each subsequent twenty-four hour period that the lock remains in locked position. lVith this end in view Ihave provided mechanism for controlling the position of the coin support so that it travels downwardly in the chute substantially the Width of one coin during each twenty-four-hour period, with the result that additional coins must be deposited to fill the coin chute to bring the uppermost coin in operative position between the arms 52 and 56 before the lock can be released.

The time-controlled mechanism comprises a driving shaft 68 mounted in suitable bearings 69 on the frame 11, which shaft is continuously driven by any suitable motive power. In the present instance I have shown a beveled gear 71 fixed to the upper end of shaft 68 adapted to mesh with and' be driven by a beveled pinion 72 mounted on a shaft 73 connected with any suitable source of power. When a bank of lockers or similar devices are-v equipped with my invention the shaft 73 will be extended and geared to each driving shaft 68 so that all the driving shafts will be actuated from the main shaft 73. Beneath and in alinement with the driving shaft 68 I have supported in a .stubbearing 74 a driven shaft 75 which receives motion from the driving shaft through suitable clutch mechanism. l/Vhile the clutch mechanism may be 4of any preferred coning shaft, the driving member 81 being adapted to engage with the driven member 76. A coiled expansion spring 84 normally holds the driving member of the clutch in the position shown in Fig. 4 and the driven member is moved longitudinally to close and open the clutch through a link 85 pivotcd at its lower end to a ring 86 rotatably con` nected with the driven member 76 and pivoted at its upper end at 87 to the extremity `of the bell-crank lever arm 49. When the lock is in unlocked position asshown in Fig. 4, the clutch member 7 6 will 'be held out of engagement With the member 8l by the latch bolt. Vhen the locking bolt is moved to locked position, howeverfthe latch 41, under the influence-of the spring 43 is urged into the deeper notch 46, thereby elevating the outer end of the arm 49 to move the clutch member' 76 into operative relation with the member 81. The driven shaft 75 is, therefore, continuously driven from the driving shaft 68 so long as the locking bolt 14 remains in locked position. The driven shaft is equipped adjacent its lower end with a worm 88 meshing with and adapted to drive a worin-wheel 89 (Figs. 4 and 6) loosely mounted on a collar 91 carried by a stubshaft 92. The outer face of the wormwheel 89 is provided with clutch teeth 93 and a clutch member 94, splined on the collar 91, is provided with similar clutch teeth 95 adapted to engage with the clutch teeth 93 and lock the rotatable collar 91 to the worm-wheel so that they will rotate together. A pinion 96 is fixed to the collar 91 in position to mesh with and drive a gear wheel 97 meshing with the rack-bar 63. The clutch member 94 is controlled by a lever 98 fulcrumed at 99 upon a bracket 101 and carrying at its upper end a roller or follower 102 which is normally urged against the rear face of the locking bolt 14 by a leafspring 103. The rear face of the locking bolt is provided with a depression 104 providing an inclined orcamsurface 105. When the locking bolt is in unlocked position the l roller 102 rests in the depression 104 and the clutch member L94 is disengaged from the worm-Wheel 89 as shown in Fig. 6. When,

however, the locking bolt is moved to locked.

four hours as 'constituting the period for.

purpose o-f illustration, it will be' manifest that the mechanism might be designed and timed to move the coin support the width of a coin during a longer or shorter period of time, if desired. It will be manifest that when the coin support has been lowered the width ofv one coin the look cannot be unlocked until another coin has been deposited `which will be supported, by the coin already in the chute, in, operative position between the bellcrank lever arms 52 and 56 so that the latch 41 will be released upon initial unlocking movement of the locking bolt. If the lock is left in looked position for more las than two twenty-four Vhour periods the coin support willl have traveled downwardly a distance which will require the deposit of two coins before an operative connection between the lever arms 52 and 56 can be established,.and eachsubsequent twenty-four hour period that the lock remains in locked position will necessitate the deposit of an additional coin. Y It will. be understood that when the lock is in locked position the coin-receiving aperture 22 is closed and the aperture 23 is opened so that the coins required to permit release of the lock are inserted through the coin-receiving aperture 23 and drop do-wnwardly in the coin groove 24 through the groove 15 in the locking bolt and into the coin chute VThe mechanism shown in the present instance is designed to provide for four twenty-four hour periods; in other words,

. the coin support is designed to travel downwardly a distance equal to the width of lfour coins, but it will be obvious that the length of the coin chute and the rack-bar mightbe increased to take care of any desired number of periods.

. In order that all of lthe coins in the lock may be deposited in a till, or other accessible position, each time the lock is unlocked, I

have provided means for withdrawing theA coin-supporting pin 64 from the coin chute each time the lockingbolt is moved to unlocked position, thereby permitting the coins in the chute to drop into a till or collection box (not shown) at the bottom of the chute. As previously explained, the head 61 carrying the coin-supporting pin 64 is pivoted at 62 on the upper end of the rack-bar and a leaf-spring 100 normally holds the coin-supporting pin in operative position in the chute. At the rear of the coin chute upon flanges projecting therefrom, I have .pivotally mounted at suitable intervals cam-shaped dogs -106 which are normally held in the position shown in4 Fig; S by expansion springs 107 (Fig. 10) pressing'against the tails 108 of the dogs. The head 61 is equipped with a pair of laterally projecting wings 109 which are disposed at an inclination, as sho-wn in F ig. 8, and when the .head is lowered these wings travel beneath the dogs 106. ll'hen, however, the locking bolt is unlocked thereby releasing the clutch 94.` as has been previously described, Ythe expansion spring returns the coin support to its upper normal position and, upon the upstroke of the head, the wings 109 ride over f the cam-shaped dogs 106 thereby withdrawing the coin-supporting pin 64 from the chute. After the head has passed the dogs the pin is returned to normal position in the chute by the spring 100'as willbe readily I understood. It Awill be manifest that the so that vthe rack-bar 63 carrying the .coin

support can be returned to normalposition by the spring 65.

The mechanism is so proportioned and timed that during the first twenty-four hour period the coin utilized to effect movement of the locking bolt to locked position will remain vin operative position between the arms 52 and 56 so that thelock can'be unv locked 4without depositing any more coins. When' the twenty-four hour period has eX- pired the coin will have traveled downwardly out of operative relation with the arms'52 and56 and the wings 109 will have rack-bar and the coins in the c hute'will be f deposited in the till. 7

In order that the single coin -in the chute may be released in case thel lock is opened during the first twenty-four hour period,. I have provided an arm 111 secured to and depending from the locking bolt 14 and providedy at its'lower end with a cam-shaped head 112 which is adapted to engageowith an upward extension 113 of the head 61 likewise provided with a cam-shaped front face adapted to be engaged by the head 112 which, upon unlocking movement ofthe bolt, swings 'the head 61 rearwardly to withdraw the coin- The extension 113 is of supporting pin. suiiicient length to be engaged by/the head 112 at any time that the lock may be unlocked during the first twenty-four hour period. During' subsequent periods the pinis withdrawn bythe dogs 106, as has been previously l*explained`` It is desirable, in the event that thelock is leftin locked position for a longer period of time thanis provided for by the length of the coin chute andthe stroke of the rackbar` that the continuously operating drive shaft be disconnected from the mechanism to obviate breakage or injury of the parts; 1With this end in view I have provided a lever- 114 fulcrumed on the frame at 115 and loosely connected at one end to the longitudinally slidable driving member 81 of the clutch and at its other end to a link 116 slidable in suitable guides 117 and provided at its lower end with a toe 118 projecting at the rear of the coin chuteinto the path of travel of one of the wings 109 on-the head 61.` When the head approaches the downwardlimit of its travelv the wing 109 en' gages the toe 118 carrying the link 116 downwardly with it to thereby rock the lever 114 and disengage the clutch member 81 gear wheels 9'6 and 97 and returnl movement of the rack-bar. rlhe parts, therefore, remain in this position with the coin-support at the lower end of its travel until the coin chute is filled by the deposited coins, the upper coin then serving to establish an operative connection between the arms 52 and 56 to release the latch 4:1, as has been previously explained. When the locking bolt is returned to unlocked position the clutch 911 is automatically opened permitting the rackbar to be returned to its upper position by the spring 65, the coin-supporting pin G4 during its upward travel being withdrawn from the coin chute to permit the discharge of the coins therefrom.

Should the look be left in locked position ,beyond the length of time provided for by the coin chute this fact should be brought to the attention of the attendant in order that the user may be required to pay the additional charges due before his goods can be released. I have, therefore, provided an auxiliary locking device which, when the rack-bar reaches the end of its downward movement automatically engages the locking bolt and`holds the bolt against unlocking movement until the auxiliary locking device has been released .by the attendant. To accomplish this purpose I have mountedl an auxiliary lock in the form of a slide 119 upon the flange 12 of the frame, the slide being retained in position by bolts or pins 121 engaged in slots 122. The upper end of the slide isprovided with a recess 123 so that the top of the slide overlies the locking bolt. A notch 124 is provided in the upper edge of the locking bolt' in position to aline with the. overlying upper end'of the slide when the locking bolt is in locked position. An expansion spring 125, interposed between a bracket 126 and the lower end of the slide 119, normally holds the slide in the elevated position shown in Fig. 4. The lower end of the slide is inturned to provide a toe 127 projecting into the path of travel of one of the wings 109 of the head 61, so that when the head approaches the downward limit of its travel the wing engages said toe and moves the slide downwardly against the force of the spring 125 to engage the overlying upper end in the notch 12.4, thereby preventing unlocking movement of the locking bolt. A loc`k128, comprising a spring-pressed bolt 129 is positioned' above the upper end ofthe slide-119 and when said slide is depressed into engagement with the locking bolt the bolt 1,29 is disposed over the upper end of the `slide and precludes disengagement of the slide from the locking bolt. The attendant in charge of the lockersis provided with a key which fits the lock 128 and this key must be utilized-to unlock this lock and release the slide before the locking bolt can be moved to unlocked position. After the attendant has released the auxiliary lock 119 the user deposits the maximum numberof lcoins provided for by the coin chute and opens the lock in the manner previously described.- In order that the attendant may know when the head 61 has reached the downward limit of its travel so that he may begin to compute the overtime charge, I have provided a sight opening 130 in the front face of the frame opposite the position that a coin will assume when the head is in lowered position. A similar sight opening 131 may be provided, if desired, opposite the upper position of a coin in the chute. To prevent tampering with the lock or disfiguration of a coin opposite these sight openings, I contemplate covering them with glass, or lother transparent material. It will be obvious that, if it should beso desired, an elongated slot might be provided in the frame extending from one end to the other of the coin chute through which the coins might be observed.

For the purpose of preventing twisting or injury to the key in case the lock should for any reason become stuck or fail to operate, I prefer to extend the end of the cylinder 34 outwardly as indicated by reference character 132 (Fig.l 2) so that the sides of the key nead will be engaged by this extension to take the torsional strain which may be exerted upon the key.

. It is believed that my invention and its mode of operation will be fully understood from the foregoing without further description.

While I have referred throughout the specification to coins as an intermediary for locking and unlocking thev lock, it will be manifest that slugs, or other suitable articles, might be employed, if desired, and that the lock may-be designed for coins or slugs-` shown and described aremerely illustrative tion of a locking bolt,.mechanism for operating' said bolt, a coin-releasable device for normally preventing locking movement of Isaid bolt., and a coin-releasable device for normally preventing unlocking movement of said bolt, said devices being arranged to be successively released by a single coin upon initial movement of said bolt in opposite directions respectively.
