COIN-OPERATED LOCK.

Specification of Letters Patent. Patented an. 21, 1913.

Application filed February 25, 1911. Serial No. 610,788

To all whom it may concern: Be it known that I, ELMER E. Prom, a citizen of the United States, residing at Carmi, in the county of \Vhite and State of .'A further object is to provide a lock having a single rot-ative disk, which disk is operable through tll't medium of a key or knob.

tures of construction, combination and arreferred to, and more particularly pointed With these and numerous other objects in view, m'y invention consists in the novel fearangement-of parts, as will be hereinafter out in the specification and claims.

In the accompanying drawings, forming part of this application, Figurev l isan elevation showing my improved lock applied to a locker door; Fig. 2 is a top plan view with the top of the casing removed, showing the positions of the various parts of the look when the locking. bolt is in its extended position; Sis a similar view showing the positions of the various parts when the looking bolt is at the extreme of itswithdrawnposition; Fig. 4 is a'hori'zontal section as seen on line 1-4, Fig. 2; Fig. 5 is a vertical section as seen on line 55, Fig. 2; Fig.6 is a detail perspective of the key; Fig. 7 is a similar view of the rotating'disk; Fig. 8 is detail perspective of the locking dog; Fig- 9 is a detail perspective of the locking bolt; and Fig. 10is a similar .view of a further detail of the device.

vIn carrying out my invention, I fer to the drawings, in which similar reference' characters designate corresponding parts throughout the several views, andin whichi 1 indicates acasing of my' lock, and 2 a removable toptherefor, the ipperfedgepf which casing *1, is provided withthe c'oiii -i receiving opening 2, said opening leading; to a coin slot 3,.within said casing,-and"ex=- shall re-' coin slot 3 leads to an additional opening in the lower edge of said casing, through which the coin is passed to a coin-collecting box, or the like 4, therebelow. A locking bolt 5 tending along one side edge thereof. This is mounted within said casing and has one end thereof normally extended through an opening 6 in a side edge of said casing, and into engagement with alocking socket 6; A leaf spring 7 has one end thereof secured to the lowerfedge of said casing adjacent the opening '6 therethe side edge containing1 h f y to allow t e rec in, and is bent upwar .end thereof to engage within a groove 8,

adjacent the outer end of said lockingbolt, thereby forcingsaidflocking bolt to its extended position normally. In order to pro- I vide for the limitation of the outward movement of such lockingbolt, a lug or stop 9, is mounted in the lower edgeof said locking bolt adjacent the groove 8 therein, and adapted to contact with the inner face of a side wall of said casing. The inner end of said locking bolt is' mounted in a slot or the like 10, formed on the outer wall of the coin-receiving slot 3, and an additional lug ll-mounted on the rear wall of said casing, contacts with the rear face of said lock ing bolt to cause the same to slide in proper alinementthroughout the operation thereof.

Rotatably mounted on. the rear wall of said casing, in the rear of'said locking bolt,

is irregularlyjshaped disk 12, which disk is provided. on its periphery with a locking lug 13, the outer edge of which is-beveled, as at 1 1, and spaced aishort distance from said lug 13, is an additionalluglli, the outer end of this locking lug being rounded, as at 16, the purpose of which will be hereinafter described. Adjoining said lug 15, on the pe-' ripheryof said disk 12, is. a cam or the like 17 which terminates at the end farthest from the lug. 15, in a notch 18, and the disk 12-is also'provided through its axial center withxa stem 19, the object of said. stem being to reoeive thereon the socket 2O of a key 21.} Said key is-jpr ovided with the a lug'13','with-an opening 25 adapted to receive ..thereinptheslugfig, and it-will'be "seen that when said jkeydsproperly positioned on the sternof the disk, and the lug thereof inserted in said opening, said diskis'a dapted to bev turned with the rotation of said key.

Pivotally mounted on the rear wall of said casing is a dog 26, said dog having the end ofthe head 27 thereof provided with a .notch or the like28, and when said notch is in effective position, the same receives therein the locking lug 13. ,The head 27' of said dog 26bein'g a slight bit heavier than the ste n 29, is adapted to normally'drop downwardly, and said dog is so positioned within the casing that when said head drops downwardly on the disk '12, the stem 29 thereof, is positioned within the C0111 slot 3.

' When properly disposed in locked position i the notch 28 of the dog 26 receives the locking lug 13, as above stated, and when-in such position, a leafspring 30 having one end thereof secured to the upper edge of said casing is bent downwardly and into engagev ment with one side of the lug 15. Atfsuch time, an additional spring 31.having one end thereof secured to thelower edge of thecasing, is bent upwardly into engagement 'vv 1th the periphery of thedisk 12, and disposed within the notch 18. When the dog is in locked position with the disk12, and the locking bolt in its extended position; a notch 32 in said locking bolt is so positioned as to have. the vertical wall 33 thereof imme-' diately adj acentthe opening 25 of said disk,

so that when the'key is properly introduced in said disk so that the lug thereof is engaged with said opening25, the extended portion 22 of said key is adapted to engage said vertic'al'wall 33, and draw said locking bolt i nwardly. As long as the notch 28 of the dog. 26 locked position with the lug 13, said key cannot be turned, but as soon assufiicient weight has been placed on thestem 29 of the dog to raise the'head 27 from its effective position, said key may 1 be turned to withdraw said locking bolt. As

the lower end of the stem 29 is disposed within the coin slot 3 when the head thereof is in locked position, it-will'be seen that any coin, which,is of suflicient weight to overcome the weight of the head, will allow the head to be removed from its efiective position, whereby the key may be turned to withdraw the locking bolt.

Mounted on said locking'bolt, adjacent its inner'end is a depending spring 34:, which is bent, so as-to be in the path of the stem 29 of said dog, thereby limiting the movement thereof in one direction, and rigidly'mounted on the rear wall of said casing is a member 35 having one end thereof extending over said disk 12, the end of said member 35., extending over the disk, being provided with a lug 36, which is adapted to extend Within the groove 24' of the depending .por-

' 5' 'tion 22 as the key 21 is 'truned past the same. It will be seen, therefore, that this member 35/actsas a-guide for the proper key 21, and at the same time acts as a stop for other keys, which may be inserted there in maliciously.

In operating the lock, it must be stated that the same is normally in locked position with the key locked therein. To open the lock therefore, a coin, of a predetermined size andhmount, is dropped through the coin opening 2', and as the same falls into" the slot 3 it contacts with the lower end of the stem 29 of the dog 26, the weight of the coin being suflicient to overbalance the weight of the head 27, and thereby swing the dog on its pivot, and removing the notch 28 from its effective position, on the lug 13.

Then by turning the' key 21-the extended portion 22 thereof will engage the vertical wall 33 of. the locking bolt 5 and draw thesame inwardlyto separate the sections of thelock, that is the locking bolt from the lockingsocket. Should the sections of the lock be upon the door and side wall of a locker or the like 35, it will be seen that the door of'said locker may be then opened and articles desired for checking may be placed therein. A continuation of thevturning of said key will, of' course, allow the extendedas the case may be. As the coin is dropped into the slot and comes into contact with the lower end of the stem 29 of the dog, the same is not adapted to drop immediately to the coin box below saidlock, as the spring 34 carried by the locking bolt, will limit the movement of the lower end ofsaid'dog to retain the cointherein .for a short period. At the time, however, that the locking bolt is freed from the key in the turning thereof, the cam 17 of the'disk comes into contact 'with theend of the head of the dog and swings the same slightly on its pivot, thereby allowingthe coin to be dropped through to-the coin box below. By the coin remams ing in the slot for a'short period, as stated, the notch in the end of the head of the dog will remain upwardly-c out of contact withbotlr of the lugs 13 and 15 as the same are being turned through the turning of the disk. As the key is turned half the circuit of its path the same will come into registration with the key-hole 37 in thetop 2, where by the keymay beremoved from thelock,

and asthe boltat thisitimehas been again forced into its extended position, as stated 7 above, to lock with the locking socket, therefor, said lock carmot-be opened except with the key which has been removed. Hence and will draw the should this lock be applied to a locker or the like for the safe checking of hats, coats, canes, and the like, it will be seen that by first inserting the coin and unlocking the lock, such articles may be placed within said locker, the door locked and the key removed. 'When it is desired to again open the door of the locker, the key may be inserted through the key-hole and the opening 25 0f the disk "12, being in position will receive the lug 23, of the key. By further turning the key, the lug 13 will come into contact with the lower end of the spring 30,

same upwardly into engagement with the outer end of the head 27 of the dog, and as the spring extends below said outer end the same engages the beveled face 1A, of said lug and prevents the notch 28 from engaging said lug. At this .time, the key is again in position to engage the vertical face 33 of the notch in the locking key, said lug 13-will pass the notch 28 in view of the spring 30 at this time, thereby allowing the locking bolt to be again withdrawn. As the locking bolt is withdrawn, however, the lower end of the spring 34 carried thereby, will engage the lower end of the stem 29 of the dog 26 to swing said dog on its pivot and position x the head downwardly into engagement with a portion of the disk, that portion of the disk that is adapted to be engaged, being the lug 15. .As this lug 15 is engaged by the notch 28 of the dog, it will be seen that the turning of the key is limited at'this time, and at the point of limitation, said locking bolt will have been completely withdrawn, allowing the door of the locker con taining this portion of the lock, to be opened, and articles therein removed. Upon the release of the hold on the key, however, at this time, the locking bolt will again be forced to its extended position through the spring 7, turning the key and disk therewith, said disk being capable of turning in view of the curved face 16 of the lug 15. As

the locking bolt is forced back to its extended position, the spring operated thereby, will, of course, release its engagement with the lower end of the stem 29 of said dog and allow the head 27 to drop toits normal position by means of gravity to again engage the lug 13, which has been moved back to its original position through the turning of the key and disk.

From the foregoing, it will be seen that the locking bolt may be twice withdrawn from its locked position throughthe introduction of a single coin in the slot, thereby making it possible for a locker or the like, containing such a lock to be first opened to insert articles for checking, then closed to remain locked and the keyremoved. No other key but the one belonging to the lock is'then capable of opening bolt, and by further turning thev the same, so that when a person desires to remove the articles from the locker, the key may be again inserted and the locking bolt again withdrawn .to open the door. As stated this is all accomplished by the insertion of one coin, and when. the locking bolt is again extended after its second withdrawal, it will be seen that thekey Will be held within said lock and cannot be removed until an additional coin has been inserted. It will further be seen that this device is adapted for use in all places wherein it is desired to check articles of wearing apparel or the like, thereby eliminating the necessity of providing an attendant for checking such articles. It will still further be seen that I have provided a lock of the character described in which there are extremely few operating parts, thereby making it less complicated than the usual locks of this character, and it will, doubtless, be appreciated that it is extremely effective in operation. I

By changing the member 35 in size and shape; by changing the size, shape and position of the opening 25, and by providing lugs of different sizes, shapes and positions on the disk 12, the style of key for operating the lock may be changed. Although I have shown and described my improved lock as adapted to be applied to a locker or the like, it must be stated that the same is equally well adapted for use in connection with a door'of a theater or other place of amusement wherein a charge is made for entrance thereto. This lock, when used in such a connection, must necessarily omit the lug 15 on the disk 12 and the spring; the cam 17 is positioned nearer the lug l8 and an ordinary knob for a door is used instead of the key 21, thereby converting the device into a single-acting lock. With thisconst'ruction the locking bolt is allowed to be withdrawn and disengaged but once with the insertion of one coin, as, will be appreciated, is necessary when applied to a pay-as-you-enter door.
