COMBINATION-LOCK.

To all l'ufiiom my concern:

1 Be it known that I, JOSIAH J. DEAL, a 'citizenof the United States, residing at Canton,

'in the county of Stark and State of Ohio, have invented certaln new and useful Improvements in Combination-Locks; andI do hereby declare that thefollowing is a full,

clear, and exact description of the same, ref-,

erence being had .to the accompanying drawings, making a part of this specification, and ,to the numerals of reference marked thereon, --in which 'Figure l is a view showing the lock open, and the locking lever set and locked." Fig. 2 -is'a. view showing the different parts and the locking lever released. Fig. 3 is a view showing the different parts in their posit-ions when the combination has been worked, and the knob spindle released and free to turn. Fig. 4; is a View showing the locking lever in position to be moved by the knob, spindle.

the locking lever and the locking lever knob and its spring. Fig. 9 is a view showing the lock open and the knob spindle free to turn and 'thelockinglever set back and free to turn. Fig. 10 is an edge view of the lock showing the casing in section. Fig. 11 is a View similar to Fig. 9, except the knob spindie is locked against rotation. Fig. 12 is a vi'ewshowing thelock proper applied to an ordinary and common lock. Fig. 18 is a view of the locking lever setting knob or spindle. Fig-let 1s a view showing a por- -tion of the lock casing showing the different spacing dlsks I and a setting disk and also showmgthelockmg disk detached.

The present invention has relation to com-- bination' locks and it consists in the difierent parts a'nd combination of parts hereinafter described and particularly pointed out-in the claims 7 Similar numerals of reference indicate corresponding parts in all the figures of the drawing.

In the accompanying drawings. 1 represents the case, which maybe of the form shown andi's formed of such a size that the ditferent 'partsintended to be located therein Specification of Letters Patent.

can be properly arranged and connected. The case 1 is secured to the ordinary lock case 2- or to a door as the case may be by means of suitable connecting bolts 3 or their equivalents. The outer knob spindle at is provided with the usual knob 5. v To the outer knob spindle a is securely attached or formed integral therewith the spindle head 6, which is provided with the screw threaded aperture 7 into whichscrcw threaded aperture is seated the screw threaded end 8 of the inner knob spindle 9.v The, spindle head 6 is provided with the lateral lug 10, which lateral lug is for the purpose of limitingthe movement of the inner knob spindle 9 by reason of the pin 11 coming in contact withsaid lug, thereby allowing the inner knob spindle tobe rotated at any time and the lug 10 is also for the purpose of coming in contact with the pin 11 so that when the outer knob spindle is rotated the inner knob spindle will be rotated with it.

The easel. is provided with the hollow post 12 upon which post are located any de sired number of spacing disks 13, toothed disks 1%,lock disks 15, said disks being varied as to number reference being had to the number of locking disks designed to be employed. In the present case three lock disks are employed but of course the number may. be increased or decreased without changing the nature of the invention but two lock disks must be employed to bring about a true combination. The spacing disks 13 are provided withthe extensions 16, which extensions are notched for the purpose of'receiv ng the pin .17, which pin is fixed to the case 1. The toothed disks it are provided with the pins 17? which pins are for the purpose of connecting the lock disks 15 by means of the apertures 18, the combinatlon being changed from t me tov tune by placing the pins 17 in. different-apertures formedin the lock disks-15.

'For the purpose of setting-the. locking disks the toothed disks are providedcwith,the

extensions. 1 l9,"- whieh extensions-are. so. 105 c'ated that when r the setting disk. 20, 1s=j r0.-

t'ated thepin 21 will engage the extensions 19 and thereby setthe lock disks so that the predetermined combination can be counted and the knob spindle released. Thelock disks are each provided with the notches22, which notches can be brought into proper .alinement with the notches 23 formed in the spacing disks l3 and the notch 24 formed in the setting disk 20. The dog'25 is 'free to be carried downward by means of the spring 26, which s ring'is located through the aperture 26 formed in the right angled portion of the dog 25 and when carried downward it releases the spindle head 6 together with the knob spindles 4 and 9.

- For the purpose of roviding a means for actuating the setting dlsk 20 the setting knob 27 is provided, which setting knob is pro-- spring so tensioned that it will have a -tend-' ency to move the dog down when free as above described.

The spindle head 6 is provided with the.

stop 34, which stop is for the purpose of preventing rotation of said spindle head 6 and the lock spindles 4 and 9.

To the casing 1 is attached or formed integi'al therewith the lug'or boss 35, upon :which lug or boss is movably mounted the locking lever 36, which locking lever is provided with the hook 37, which hook is lo- .cated below the lateral lug'33 formed upon the dog 25, said hook being for the purpose offfenga ingsaid lateral lug. for thepurpose hereina er described.

The spindle head as provided with the cam In 38, which cam lug'is for the? purpose of engaging the pin, 39, which pin is" connectedto the locking lever 36. 'It will be understood that when the locking lever is located as shown in Figs. 9 and 11 the cam lug' 38 will not come in contact with the pin 39,.but will pass said pin without coming in contact therewith; butwhen the locking lever is brought into the position shown in Figs. 1, 2 and 3 the cam lug 38 will engage the pin 39 and move the locking lever 36 downward as illustrated in Fig. 4, and when the hook 37 has come fully under the lug 33 the spring 40 will move the locking lever up carrying withit the dog 25; but this movement cannot take place until the shoulder 34 has been carried out of the way of the dog and in order to automatically do this the s ring 41 is provided, whichspring forces the spindle head 6 into the positlon shown 1n Fi l.

For the purpose of limiting the back action of the spindle head 6, the pin 42 is prosame into properposition to be a ctuat'ed'b Having For the purpose of actuating the lock for -a given combination, the movable bars 43' areprovided and are located side by side as best illustrated in Fig. 10, their uppexgends being held by the guide 44, which guide is connected to the lock casing 1 in any con- -VI116Ilt 2111(l well known manner. To the loperating bars 43 are pivotally attached the fingers 45, which fingers are for the pur-' 159% of engaging the eeth upon the'toothed [disks 14.

disks 14, thesprings 46 are provided,- which.

springs are connected to the bars 43 and causing the fingers 45 press'against the shoulders 47. When-it" is.

desired to bringthe locking lever 36 out of action the knob 48 is moved upward as illustrated in Figs. 9 and-'11, butwhen it is desired to bring the locking lever into action the knob 48 is pushed down, which knob carries the cam plate 49, Which'cam plate comes in contact with thelockinglever 36, and moves its lower end so asito .bring'thethe cam lug 38 and the pin 39.

For the purpose of automatically lower:

ing the operating bars 43-the springs 50- are provided -the ends of which springs are located in the notches 51 1 formed in the bottom or lower. ends of the bars 43. a It will be understood that the bars 43 should be provided with 'operating' knobs 52, which knobs extend through the casing 1.-

Forthe purpose of moving. the. looking lever back after it has been moved by the knob 48 the setting 'disk'20 is provided with the pin 53 which pin Icomes'in contact with;

moves the lever into the fully described my. invention what I claim as new and desire to secure by,
