LOCKER.

Specification of Letters Patent.

1 atented Apr. 6, 1915.

Application filed. August 10, 1914:. Serial No. 856,063.

T0 all whom 'it may concern Be it known that I JOHN GRIESMAIER, a citizen of the United States, residing at Ghicago, inthe county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Lockers, of which the following is a specification.

The locker which is the subject matter of the present application for patent is designed more particularly for use in hotels, restaurants, barber shops and similar places, its object being to provide a safe place for the customers wraps, hat, umbrella., etc.

The invention also has for its object to provide a novel and improved coin or checkcontrolled lock for the locker.

In order that the invention may be better understood, reference is had to the accompanying drawings, in which- Figure 1 is a perspective view of the locker; Fig. 2 is an enlarged vertical section thereof; Figs. 3 and L are elevations of the doors forming the closure of the locker; Fig. 5 is an elevation, partly in section, showing the lock; Fig. 6 is a view similar to the preceding, showing the parts in another position; Fig. 7 is a horizontal section on the line 7-7 of Fig. 5; Fig. 8 is a horizontal section on the line 8-8 of Fig. G; Fig. 9 is a face view of the coin or checkcontrolling means of the lock, and Fig. 10 is a perspective view of a portion of the lock housing.

Referring specifically to the drawings, the locker is a tall boX-like structure having sides 12, a back 13, a top 14 and a bottom 15. The front wall of the locker comprises top and bottom sections 16 and 17, respectively, which are spaced to provide an opening through which access is had to the interior of the locker. This opening is provided with a closure comprising two sliding doors 18 and 19, respectively. In the locker, a short distance above the bottom 15, is a false bottom 20, beneath which is located a shallow pan or dra-wer 21, slidable into or out of the locker through an opening in the bottom front wall section 17. The false bottom has perforations 2Q, and its purpose is to support an umbrella, the latter being stuck into one of the perforations 22. If the umbrella is wet, the drippings will be caught in the pan 21.

The doors 18 and 19 are screened as shown in Figs. l to 4, and they slide, one in front of the other, in grooves 28 formed by strips on the side walls 12, said grooves being separa-ted by a parting strip 21. On the inner face of the top and bottom rails of the lower door 19 are longitudinal ribs 25, and on the outer face of the top and bottom rails of the top door are longitudinal ribs 26. l/Vhen the two doors are slid upward to closing position, the top rib 25 and the bottom rib 26 meet, and if the upper door 18 is locked, the lower door is held by the ribs from being slid downward to open position. All the ribs, except the bottom rib of the lower door stop short of the side edges of the doors so that they may clear the parting strips 21, and said bottom rib serves to prevent the lower door from being slid upward after it reaches its closing position, said rib being then in contact with the bottom of the parting strips, the latter therefore serving as stops to limit the upward travel of the lower door. The parting strips do not extend down to the bottom of the door way but stop a suilicient distance thereabove, so that when the doors are slid downward to open position, they seat below the parting strips as shown in Fig. 2. In order to cushion the doors when they are slid down to open position, a rubber or other cushion 27 is mounted at the bottom of the door way.

The locker will be provided with suitable garment hangers, as shown in Fig. 2.

rlhe following check or coin-controlled locking mechanism is provided: On the outer face of the top section 16 of the front wall of the locker, over an opening in said section, is mounted a plate 2S, on the back of which, and consequently on the inside of the locker, is a coin chute formed by laterally spaced, parallel vertical ribs 29 and a cover plate 30 extending across the latter. The ribs form the side walls of the coin chute and their upper ends, where the coin or check is inserted, are flared as shown at 31 and project from the top 14 of the locker. In the entrance end of the coin chute are mounted two opposed bowed springs 32 which accelerate the drop of the coin or check. rIhe springs spread as the coin or check is inserted, and when the latter is forced past the springs, they draw together and snap the coin or check down the chute. At the bottom of the coin chute is an inclined shelf 38 which deiects the coin or check into a receptacle 34 hinged at its rear end, at 35, in an opening in a horizontal partition 36 mounted in the upper portion of the locker, and cutting off this p'artof the locker from the other part in which the garments, etc., are placed. A suitable lock 37 is provided for holding the receptacle up. Upon unlocking the receptacle and tilting it down, as shown dotted in Fig.V 2, and opening the doors 18 and 19, access may be had to the coins or checks in the receptacle.

1n the plate 28 is a key hole or slot 38, and below the latter the plate has an aperture 39 for a bolt 40 carrying a chain 41 which is connected to the upper door 18 and is of such length that when said door is closed and the bolt is in place and locked, said doorcannot be slid down to open position. The opening of the lo-wer door 19 is prevented by the means hereinbefore described. Y

On the back of the plate 28, to one side of the coi-n chu-te, is mounted a vertical slide 42 comprising` a flat plate held in place between undercut guide ribs 43 on the plate 28. The slide has a vertical slot 44 divided by a cross bar 45 into upper and lower sections, the top of the former being reduced in width, as indicated at 46. The upper slot section registers with the key hole 38, and the lower slot section registers with the aperture 39. The lower end of the slide reduces to a narrow strip 47 having an outstanding flange 48.l Y

To the back of the plate 28 is pivoted a lever, one end 50 of which is below and in line with the coin chute so as to intercept the check or coin falling down the chute. This end of the lever is widened so that the check or coin may not miss the same. The other end 51 of the lever is positioned so that it is in contact with the flange 48. The end 50 is normally positioned across the lower end of the coin chute. A check or coin dropping down the chute, upon striking the end 50, tilts the lever, so that the end 51 swings upward, andas said end engages the flange 48, the slide 42 is carried upward. As the coin clears the lever, it drops on the shelf 33 and is deflected intoy the receptacle 34.

Against the back of the plate 28 is mounted a housing which incloses and supports the remaining parts of the lock which will now be described. This housing comprises two laterally spaced vertical plates 52 and 53, respectively, having at their rear vertical edges outstandingy flanges 54 which are bolted or otherwise secured to a supporting arm 55 carried by the back 13 of the locker. The forward vertical edge of the plate 52 abuts against the back of the plate 28 over the slide 42, said edge having a recess 56 to accommodate the Slide.

On the plate 52 are mounted' two vertically spaced, horizontal guide strips 57, the

plate 52.

spacebetween the same being in alinement with themkey hole 38. To the rear of these guide strips' isy mounted a series of main tumblers, which are angular, each tumbler comprising two arms 58 and 59, respectively. The tumblers are pivotally mounted, side by side, on'a pin or stud 60 carried by the The arms 58 of the tumblers point upward, and the arms 59 are horizontal and point toward the slide 42. The upper end of the arms 58 are in line ,with the ace between the may be engaged by the key 61, said ends being reduced. to different widths and the inner end of the key being correspondingly shaped as shown at162, in Fig. 8. Thus a special key, corresponding to the arrangement of tumblers, or the combination, is necessary. The proper key, when inserted through the key hole 38 and pushed against the upper ends ofthe tumbler' arms 58, will swing the latter as one on the pivot 60. The strips 57 guide the key to the tumblers.

The tumbler arms 59 have bottom hooks 63 at their forward ends to engage an abutment 64 on the inner end of the bolt 40 and thus prevent withdrawal of the latter. However, when the tumblersare operated to disengage the hooks from the abutment, the bolt may be withdrawn and the door 18 is then free to be slid down to open position. The plate 53 carries a guide 65 for the bolt.

Above the arms 59 of the main tumblers is mounted a series of auxiliary tumblers 66, which are substantially U-shaped, the two branches pointingl downward. These auxiliary tumblers are pivotally mounted at the connecting portion of their branches on a pin or stud 67 carried by the plate 52. The rear branches seat on the top edges of the branches 59 of the main tumblers, said edges being slightly recessed to form a seat, as shown at 68. The forward branches of the auxiliary tumblers terminate in a forwardly extending finger 69 designed to enter thel slot 44 to engage the bottom of the cross bar 45 and hold the slide 42 elevated. When the fingers 69 are withdrawn from the cross bar, the slide is released so that it may drop by gravity.

The function of the slide 42 is to prevent withdrawal of the key 61 after it is inserted in the lock; The shank of the key, adjacent toits bow or handle has a reduced neck portion 70 forming transverse notches in opposite edges of the shank. The opposite side walls of the reduced upper end 46 of the slot 44 are designed to seat in these notches,

key cannot be and when thus seated the withdrawn. v

Proper return springs 71 for the main and auxiliary tumblers are provided. The main tumblers swing between stop lugs 72 on the .Y

plate 52. y Y Y.

O'n the plate 53' is an outstanding horizontal rib 73 positioned to seat in a longitudinal side slot 74 in the bolt 40 when the latter is inserted into the lock. r1`hus, the bolt can only be inserted one way, which is sure to be the proper way. The bolt also has a bottom rib 75 to take a reduced bottom portion 7 6 of the aperture 39, which prevents lateral motion of the bolt which might injure the main tumblers.

A pin 77 carried by the plate 28 and extending into the slot 44 serves as a stop to prevent the slide from dropping down too far.

lThe key hole 38 has a reduced bottom portion 7 8 which acts in conjunction with a lug 79 on the under side of the key 61 to insure the proper insertion of the key.

The operation of the lock may be summariZed as follows: When the bolt 40 is out of the lock, the door 18 is free to be slid down to gain access to the locker. The coin actu ated lever 50, 51 is normally in the dotted line position shown in Fig. 9, the slide 42 being down and the part 46 of the slot 44 locking the key 61 in the key hole 38. The last previous insertion of the key operated the main and auxiliary tumblers and placed the same in the position shown in Fig. 6, the main tumblers having been swung to release the bolt, and the auxiliary tumblers having been swung to release the slide so that it was free to drop down to lock the key. The lock is now inoperative as the key cannot be removed. lt a person now wishes to use the locker, and after placing the garment, hat, etc., therein, he drops a coin or check of the required denomination into the coin chute, and after raising the doors 18 and 19, the bolt is inserted. As the coin or check drops down the chute and strikes the part 5() of the lever, the slide 42 is pushed upward to release the key, and the bolt is locked by the hooks 63 of the main tumblers. The lingers 69 of the auxiliary tumblers also come under he cross bar to lock the slide against downward movement. rIhe bolt is now locked, and the key may be removed and kept by the person using the locker until said person wants to remove the garment, hat, etc., the parts being in the position shown in Fig. 5. To unlock the bolt, the key is inserted to operate the main tumblers, whereupon the parts again assume the position shown in Fig. 6, and the bolt is unlocked, the key being again locked as hereinbeore described. The bolt being unlocked, it may be withdrawn to open the locker doors, and the parts are now ready for the next Person desiring to use the locker.

It will be seen from the foregoing that G'opes of this patent may be obtained for the locker doors cannot be locked without inserting a coin or check. 1f a key is lost or stolen, the lock can be opened to change the combination and a new key supplied, thus rendering the original key useless.
