Specification of Letters Patent.

Patented Oct. 15, 1918.

Application led J une 22, 1917. Serial No. 176,357.

To all whom t may concern:

Be it known that I, PERoIvAL H. ATKIN- SON, a citizen of the United States, residing at Burns, in the county of Harney, State 0f Oregon, have invented a new and useful Lock Mechanism for Public Lockers and the like; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved lock mechanism for public lockers of various public places and the like, or for parcel receiving receptacles or compartments and the like, and an object of the invention is to provide a device of this kind, which will dispense with the services of an attendant or the like.

A further object of the invention is to provide a simple, eliicient and practical device of this kind, having means to be manipulated, by means of a coin or slug (which may be any suitable size desired) for locking said mechanism, thereby releasing a specal key or slug, with which the mechanism may be unlocked.

A further object of the invention is to provide an improved lock mechanism having a pair of tumblers, so mounted and working on pivots, as to be overbalanced by means of a weight, coin or slug, whereby, when the bolt is thrown into engagement with its keeper, said tumblers will lock the bolt in such position. The tumblers will then grip each other in such manner that the objective end of the lower tumbler will require theweight of a slug, coin or the like, to oscillate the lower tumbler, in order to release or unlock the bolt, and when the lower tumbler is oscillated and both tumblers are at neutral positions, the bolt may be moved from its keeper.

A further object of the invention is to provide a pair of chutes or passages for the slugs, coins or special slugs, whereby the tumblers may be actuated, there being means carried by the bolts to cover first one, then the other of the entrances to said passages, to prevent the slugs or coins from being inserted into one or the other'of said passages.

In practical iields, the details of construction may necessitate alterations falling within the scope of what is claimed.

The invention comprises further features and combinations of parts, as hereinafter set forth, shown in the drawings and claimed.

In the drawings Figure 1 is a view in elevation of the improved lock mechanism for lockers of various public places, for instance, such as bath houses, check rooms and the like.

Fig. 2 is a view in elevation, showing the face plate of the casing of the mechanism removed.

Fig. 3 is a view in elevation of the lock mechanism, showing the face plate of the casing removed and the tumblers of the mechanism in their neutral positions.

Fig. 4 is a view in elevation of the lock mechanism, showing the face plate of the casing broken away in parts and illustrating the tumblers as having been moved to their limits justthe opposite to that shown in Fig. 2, and the bolt unlocked and thrown.

Fig. 5 is a sectional view on line 5 5 of Fig. 3.

Fig. 6 is a cross sectional view on line 6 6 of Fig. 3.

Fig. 7 is an enlarged detail view in perspective of the locking bolt.

Referring more especially to the drawings, 1 designates a suitable casing, which consists of two sections, a body or receptacle section 2, and a face plate or top section 3, which may be secured to the body or receptacle section by means of suitable screws a. The body or receptacle section is provided with a marginal flange 5, and eX- tending inwardly from the longitudinal portions a of the flange, are auxiliary flanges 6, which have outturned parts 7, thereby forming coin or slug channels 8 and 9, through which coins or slugs may pass. Mounted in guides 10 formed oppositely to each other in the longitudinal parts 5a of said flange 5 is a locking bolt 11. Substantially midway the ends of the bolt 11, on one face thereof, a recess 12 is formed.

Suitable metallic straps 13 arch over the locking bolt 11, to additionally guide the same, and which straps are secured at 14 to the receptacle section of the casing. On the under surface of the locking bolt 11, adjacent its ends, are notches 15 and 16. A suitable U-shaped tumbler 17-is provided,

and which comprises the side arms 18 and 19, the lower terminals o f which are pro vided with laterally bent parts and 21. Projecting upwardly and centrally from the arch 22 of the U-shaped tumbler, is an eX- tension or tongue 23, which is mounted upon the pin 24, thereby pivotally mounting the tumbler, so that it may oscillate in the manner hereinafter set forth. Near the opposite ends ofthe arch 22 of the U-.shaped tumbler, upwardly projecting lugs 25 and 26 are provided, adapted to alternately engage the notches 15 and 16 of the bolt 11, in the manner hereinafter set forth. The auxiliary flanges 6 are provided with cut away portions or openings 27 and 28, which will alternately receive the laterally bent portions 20 and 21 of the arms 18 and 19 of the tumbler 17. Pivotally mounted upon a pin 29, which projects from the inner face of the back wall of the receptacle section is a tumbler or oscillatory member 30, which is provided with downwardly curved ends or p0rtions 31, which play between the auxiliary 'flanges 6 and the face plate section 3 of the casing. In order that the curved portions 31 may play in the channels or passages 8 and 9, the outward-ly bent parts or flanges 7 are cut away, as shown at 32 and 33. The lower part of the receptacle section of the casing, as shown at 34, is designed =to receive the coins, which are used to operate the mechanism. One of the ia-nges 6, below the cutaway portion 28, is provided with an additional cutaway part 35. A partition 36 rises, upwardly from the lower part .of the marginal flange 5 of the receptacle casing, thereby dividing off a compartment 37 for the slug 5 that enters the channel or passage 9, and which slug may be removed from the compartment through the opening 38 of the face plate section of the casing. The face plate section of the casing is provided with an opening 39, which, as shown, is covered by a closure 40, which may be locked in any suitable manner. By unlocking the closure 40, the coin deposits may be removed from the compartment or magazine 34. Secured at 41 te the locking bolt 11, is a bar 42. rIhe upper part of the bar 42 inclines upwardly to one side and terminates in a horizontal portion 43 having a bent part 44, which, when the locking bolt is in locked position, covers the entrance opening to the coin passage or channel 8, thereby preventing a coin from passing into said channel. The lower part of the bar 42, at its lower end, has a .la-tleral portion 45, which is provided with an outwardly turned tongue or lug 46, which plays in the cutaway part of one of the flanges 6. Theextension ortongue 23 extends through the recess 12. A rocking member 47 has its shan-k 48 ymounted in suitable bearings .of ,the receptacle and face pla-te sections .of the casing. ..48 et said rocking inember .47 has a .lateral The inner .end .of the Shank extension 49, over which a metallic strap 50 arches to guide the extension or part 49 as the member 47 and its shank are rocked. rlhe end part 51 of the extension 49 engages the notch 52 of the locking bolt 11.

On the outer face section 3 of the casing is a suitable key or slug entrance controlling mechanism 53 of any conventional construction. An example of this mechanism 53 can be found in the application of I). H. Atkinson, filed September 27, 1916, Serial Number 122,458, therefore, so far as the operation and rthe structure of this mechanism is concerned, it is immaterial and entirely unnec essary to enter into a lengthy disclosure of the same inthe present case. However, it might be said that the mechanism of the aforesaid co-pending application is designed mainly to provide an entrance controlled mechanism, whereby the entrance opening 54 may receive a specially designed slug, whereby the presen-t lock mechanism may be operated for a predetermined period, so as to limit the rental 0r the use rof the locker, and which entrance opening lmay be altered in sh ape to receive varied shapes of slugs.

In using this mechanism, the door of the locker is normally unlocked, preferably open. The person to use the locker may drop a coin through the channel or passage 8 at its upper end. However, the entrance opening to the passage 8 may be provided with a .mechanism similar to 53, and in this case the person to use .the locker may buy or purchase a. special slug, which may be passed through the channel or passage 8. In either case, however, the coin, slugor weight, as indicated at a, contacts with one of the curved parts 31 of the oscillatory tumbler 3.0, thereby moving the same to a substane.

tially neutral position, as shown in Fig. 3, until the terminal of' the y.curved portion 31 (which is so engaged by the coin or slug) contacts with the lateral portion 2() ofthe arm 18 of the U-shaped tumbler 17, ,thereby overbalancing the tumbler 17 to its neutral position, as shown vat 23. When these parts are so operated, the coin a is supported, as shown in Fig. 3. The operator then rocks the member 47, causing the extension 49 to throw the bolt 11 to a locked position, as illustra-ted in Fig. 4. Vhen the bolt is moved to this position, lthe coin further over balances the tumbler 30, allowing the coin to drop into the compartment 34, and owing -to the extremity 5,5 of the curved portion 31 having .been in engagement with the lateral part 20, the tumbler 17 is tilted from its neutral position in Fi-g. 3 to the position shown in Fig. 4, until the lug -26 engages the' notch V16, thereby holding ,the bolt in its locked position. When the bolt is moved to the positlon shoWll in Fig. 4, the lateral lug .46 (which Supports the elugor Weight ,as Shown in Eig .3) is more@ .fram the rath of the slug b, releasing the same and allowing it to fall into the compartment 37, where it may be removed by the person or operator who in the rst instance purchased cr rented the locker. When the operator or person renting the locker desires to open the same after inishing bathing or for removal of that which is being temporarily stored therein, deposits the slug b in the passage 9 through the entrance opening 511. The slug will then contact with the curved portion 31 at the right hand end of the tumbler 30 and cause the tumbler 30 to become overbalanced until its extremity 56 will contact with the lateral lug 21 of the arm 19 of the tumbler 17, in a manner similar to the engagement of the extremity with the lateral part 20. Just so soon as this is accomplished the tumbler 17 becomes overbalanced until its lug 25 engages the notch 15, that is when the bolt 11 has been moved to the position shown in Fig. 2, in which case, the various tumblers will assume the positions shown in Fig. 2, with the bolt locked in an unlocked position in readiness to be unlocked by a coin of another person purchasing the locker.
