WILLIAM HERMAN KLUGE, OF INDIANAPOLIS, INDIANA, ASSIGNOR TO THE COIN CONTROLLING LOCK COMPANY, OF INDIANAPOLIS, INDIANA, A CORPORATION 0F INDIANA.

INDICATOR FOR COIN-CONTROLLED LOCKS.

To all whom it may concern:

Be it known that I, WILLIAM HERMAN KLUGE, a citizen of the United States, residing at Indianapolis, in the county or' Marion and State of Indiana, have invented certain new and useful Improvements in Indicators for Coin-Controlled Locks, of which the following is a specilication.

This invention relates to improvements in coin-controlled locks and the object is to provide an indicator which will be controlled by the same coin that controls the lock and thereby indicate whether the room is occupied or open I accomplish the objects of the invention by the mechanism illustrated in the accompanying drawings, in which- Figure l is a front inside view of my improved lock with the inner plate of the case or housing removed, the view showing the bolt in its outer shot position. Fig. 2 is a like view showing the bolt in its inner shot position. Fig. 3 is a detail in vertical section on the line 3-3 of Fig. 2, and Fig. 4 is a detail in end view of the dial shaft showing all of the parts in front of the bolt plate assembled thereon.

Like characters of reference indicate like parts throughout the several views of the drawing.

10 represents the casing within which the parts of my invention are assembled. It comprises an outer plate 12 having integral sides 11 at right angles thereto, and an inner plate 14 (see Fig. 3), which is removably secured to the casing.

The main bolt of the lock is shown at 16, the body of which is 4flat and comparatively thin and has its bearing against the plate 12. One end of the bolt is reduced in width to form a part 17 which is projected through a suitable opening in the side 11. The opposite end of the bolt is reduced in width to form shoulders which will limit the outward movement, and this end is thickened to form the part 19 which passes through the adjacent side 11 of the casing to engage a strikin plate (not shown). The increase in thickness at this end of the bolt forms the shoulders 21. A lever 23 havinov an upper bent end 22 is mounted on a shat 24 which shaft is supported by the two

plates

12 and 14 of the casing and is extended outside of the latter and terminates with a suitable Specification of Letters Patent.

knob or handle (not shown). The bent end 22 of the lever is attached to one end of a spirally wound spring 27, and the opposite end of this spring is attached to a plate 28 which is secured to the plate 12 of the easing. The plate 28 extends in a downwardly oblique direction to serve the additional purpose of a guide to direct the coins deposited in the lock, into a suitable receptacle at the bottom of the casing. The end of the bent portion 22 of the lever 23 is held in constant contact with the shoulder 21 of the bolt by the spring 27. The lower end of the lever 23 is continued below the pivotal point 24 to contact with a shoulder 25 formed in the plate 28 whereby the movement of the lever in that direction is limited.

30 is a coin-chute, the lower end of which discharges within the casing above the bolt 16. Mounted on the bolt 16 so as to be directly under the discharge end of the chute 30 when the bolt is in its outer shot position, is a continuation 33 of the chute, the upper end of which will preferably be expanded into a funnel to insure the delivery of the coin from the upper section 30 to the part 33. An outwardly and upwardly bent plate secured to the casing has its upper edge extending across the discharge end of the chute extension 33 far enough to prevent the discharge of a coin from said chute eX- tension while the bolt is in its outer shot or locked position. The chute extension 33 has a transverse notch39 in its lower end to permit the upper end of the lever 23 to travel through said chute extension except when prevented by the presence oi a coin 37 therein. When t-he notch 39 is closed by the presence of the coin in the part 33, the lever 23 by contact with the coin will shoot the bolt 16 inwardly of the casing thereby unlocking the door, and as soon as the bolt moves far enough to cause the coin to pass the end of the bent plate 35, the coin will be 'tree to drop by gravity, and. should it fall too far to the front ol the casing it will be directed to the rear by the oblique plate 28. The throw of the lever 23 is arrested by the contact of its lower end against the shoulder 25 of said plate 2S, and a person manipnlating the knob on the shaft 24 will invariably release his hold upon the knob at the arrest of the lever 23 by contact with shoulder 25 so that if the coin has not been previously released, it will be upon this occurrence and will drop to the bottom of the casing. Y

42 is a key mountedin the lock-casing so as not to be removable therefrom, and having its stem extended outside and squared to fit the socket of a removable extension carried by a porter or other attendant who has occasion to Vfrequently enter the room.

Supported by the lock-casing, between the bolt 16 and plate 14, parallel with the latter, is a plate 43 having a round hole to receive the reduced end of a dial-shaft 44. Mounted on the shaft 44 is a pinion Wheel 45 having a blank portion 46 to limit its rotation. The shaft 44 extends through the plate 14 with a sliding fit. Loosely mounted upon the shaft 24 is a plate 48 having a circular segment of which the center of shaft 24 is the axis,rprovided with teeth 49 to engage the teeth of the pinion 45.V Lugs 50 atV each end of the toothed segment help to limit the travel of the plate 48. y

Mounted Von the dial-shaft 44 and Voverlapping the pinion 45 and toothed edge of plate 48 is a washer 52 which is held yieldingly against both of said parts by a spring 53 wrapped around the shaft- 44 and located between the washer 52 and plate 14. By this manner of 'applying the spring the various movable parts are held in proper operative relation without binding, thereby leaving the dial-shaft always free to turn, which is essential for a reliable indicator.

54 is the dial bearing the proper inscriptions as Occupied and Open, and having a stem 55, here shown as square in cross section, to it in a corresponding longitudinal opening in theshaft 44.

Located between the plate 43 and the bolt 16 is abentbar, one end, 56, of which, extends outside of the lock-casing and is provided with a knob 57. The extension 17 of the bolt 16 has a longitudinal slot'58 through which the knob 57 is passed and because of the slot 58 a limited movement of the bolt 16 is permitted without moving the bent bar or lever. After the bolt 16 has been shot inwardlyV to the position shown in Fig. 2, and the indicator mechanism moved substantially to the position there shown, the bolt will'be returned by the action of the spring 27 through leven23, leaving the indicator mechanism undisturbed, and the coins inserted in the chute 30 while the room or booth is occupied will not aect the adjustment of the parts of the indicator mechanism. The end of the inner portion 60 of the bent bar terminates with a lateral extension or bent part 61 which passes through a slot 62 in plate 48 concentric with shaft 24, and the edges of this part 61 will preferably be notched to engage the plate 48 on each sideof the slot to prevent the withdrawal ofthe part 61 except when the Vlatter is turned lengthwise of the slot, which does not occur while the parts are assembled in the finished condition. Y

When the person in the roomor booth desires to retire from same, he will unlock the door by an outward movement of the knob 57. The first periods of this movement will be permitted by the slot 58 without moving I the bolt 16, but when the outer end of said slot is reached, the bolt will be moved so as to unlock the door and at the same time the end 61 of the bent bar orl lever 56-60 will return the segment-plate 48 to the position shown in Fig. 1, which will rotate the shaft' 44 and expose the Open inscription on the dial. The dial will be set to the position of Occupied by inserting a coin in chute '33 and moving the plate 42 by pressing the coin Vagainst it by lever 23 and knob of shaft 24, but the plate 48 will remain in the position thus given it until Vit is moved back by the above outward movement of knob 57 and lever 56-60.

Having thus fully described my invention, what I claim as new and wish to secure by Letters Patent of the United States, is
