LOCK.

Specification of Letters Patent. i Patented 1 22, 1921 Application filed April 30, 1919. Serial No. 293,701.

To all whom it may concern:

Be it known that I, HENRY D. GnrMns, a citizen of the United States, resident of Cleveland, county of Guyahoga, and State of Ohio, have invented new and useful improvements in Locks, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other invention My invention relates to looks and particularly to an improvement in dead or dormant locks, 1'. 0., the bolt or bolts are actuated in both directions by manually operatedmeans and not in one direction by automatically operating means such as springs. More particularly, my invention relates to looks in which two movable bolts are provided, the actuation of one bolt resulting in the locking and unlocking oi the keeper and the actuation of the other bolt resulting in the separation or bringing together oi the keeper and the cooperating locking means.

The annexed drawings and the following description set forth in detail certain means embodying my invention, the disclosed means, however, constituting but one of the various mechanical forms in which the principle of the invention may be applied.

of a fragmentary portion of the lock, the

tumblers being removedy Fig. 6 represents an elevation taken from the plane indicated by the li VI .V1

Fl 2' r a u o %1g.7 represents a view similarto Fig. 2

of a fragmentary portion of the lock. from which the tumblers have been removed;

Fig. 8 representsa side elevation of the lock closed, various elements being shown retained thereby which it is desired shall not be removed or tampered withby unwarranted persons;

r Fig. 9 represents a fragmentary elevation in which one set of two sets of tumblers has been actuated by the key through a portion oftheir path of movement, resulting in a beginning or the unlocking movement of the latch and cooperating means; y

i Fig. 10 represents a view similar to Fig. 9 in which the unlocking of the latch and cooperating locking means has completely taken placeand inwhich the separation of thei bolt and latch has partially taken place; Fig-.11 represents an elevation of the actuating key. y Referring to the annexed drawingsfl provide a suitable casing or main support 1 provided with a front cover 2 adapted to be secured to the main portion 1 by means of small tongues, not shown, struck up from the material of the cover 2 and inserted through the slots 30f the main casing l and bent over back of said main casing 1. Suitably mounted upon said main casing l is a stud or pin 4 adapted to project through the eye 5 of a keyhole formed in the cover 2, said keyholehaving a slot portion 5. The stem ofthe key 6 is adapted to be i111 sorted through the eye 5 upon the pm at, the slot 5'receiving the shank 6 of said key provided with bits hereinafter fully described, ior actuating the bolts, tumblers and other allied mechanism hereinafter fully described. 1

Supported upon the casing 1 immediately abovethecover 2, is a rail 7 formed with a horizo ntal longitudinally disposed slot 8, in which a vertically disposed bolt arm 9 carrying a horizontal,longitudinally disposed bolt 10 is adapted to play. Said rail 7 is formed adjacent its other end with a hole 11 through which a verticallydis posed bolt 12 formed with a head portion 13 is adapted to play. Said head member 13 isformed with a laterally disposed slot 14 intersecting one side thereof and of a greater width at the bottom, indicated by the ordinal 16, than it is at the top, indicated bythe ordinal 15, Fig. 6. The head 13 thus formed is adapted to act as a latch and to cooperate with locking mechanism I 7 slot 23 formed in bolt nism for thus actuati w ll now be descr bed,

formed upon the outer end of the'bolt 10.

Thiscotiperation is effected by reason of the fact that said outer end of the bolt 10 is of a shape plainly shown in cross-section in Fig. 4:, the ordinal 17 denoting the tapered shoulders thereof. 'Thesetapered shoulders cooperate with similarly tapered walls 14E of the opening'ld, so that when said shoul ders 17 and Walls 14: are alined, and the bolt ,10 and bolt 12' are in the position shown in 1,'the latch 13 and bolt 10 can not be separated. 7

It is evidentfrom the mechanism hereinbefore described that, in order to unlock the mechanism when it is in the position shown in Fig. 1, it Will be necessary first to raise the bolt 12so that the locking mechanism 17 of thebolt 10' canbe freedfrom the narrow portion l5.of the slot 1 1 in the latch 13 and then, having thus'potentially unlocked the mechanism, posltively separating the bolt 10 and latch 13, tothe position shown: in Fig. 2. The detail of the mechag-the boltslO and 12 Ther'e is secured to the bottom of the bolt 12, a plate18 having a notched front edge 1 indicated by the several portions 19, 20; and 21. f The bit 24: of the key shank 6- is adapted to actuate said plate 18 by means of acting uponthe notched portions 19, 20 andf21,'proper alinement and guides for the consequent actuation v of the bolt 12 being -furnished bythe pin 22 secured in the case 1 and adapted to play in an elongated 12. A further suitable alinement is provided by means of the "pin 25 'seouredto the case 1 and adapted .toiplay in the slot' 26 formed in the plate 18. 'There is carr-ied upon-the. plate 18 a I projection'for stump 18 whose purpose will now be described in detail. Before the key "bit 24*ca'n play upon the plate 18, it is necessarythat the, proper cooperative actions'of' a set of tumblers 27 now to be described, shall take place. .There are provided anydesired' number of tumblers 27 in this set and, for purposes of illustration,

.1 have shown a set of two tumblers 27 in the accompanying drawing. These tumblersare pivoted upon the pin25 and are resiliently held by me'ans of bent wire springs {31 secured to said tumblers in the manner plainly shown in the accompanying {drawings and bearmgat. one end upon a pin; 32"seci1red in'case 1.v These tumblers ;are' provided with communicating slots 28,

29 ;-and 30. They are also provided with ofthe tumblers 27, the stump 18 secured to the plate 18 is adapted to travel from the slot portion 28 to the slot portion 29 or vice versa, and through the intermediate slot portion 30. These slot portions 30 of the several tumblers of a set form one coutinuous vertical aperture so that it is evident that the key-bits must actuate the several tumblers the exact distances required in order that the stump 18 may pass through all of the said slot portions 30 simultaneously. It is evident that when the lock is in a closed position and it is desired to unlock the same, the key will occupy the position relative to the plate 18 and the tumblers 27, shown in Fig. l. The actuation of the key to the position shown in Fig. 9 will result in the contact of the bit 2% and the upper wall of notch 20 and in the partial vertical actuation of the bolt 12 plainly shown in said figure and the actuation of the tumblers 27 to the point where the stump 18' is passing through the slot portions 30, assuming that the keybits 2% and 33, and the notches 19, 20 and 27 have been properly coordinated. A further actuation of the key will result in the bit 24 further pushing against the upper wall of the notch 20 of the plate .18 and moving the plate 18 and bolt 12 to the position plainly shown in Fig. 2. This has resulted in the potential unlocking of the latch 13 and the cooperating locking members 17 on bolt 10. It is now necessary to positively separate the bolt 10 and latch 13. This is effected by the mechanism now to be described.

Guided upon the case 1 by means of slots in which pins 36 secured to said case are adapted to play, is a movable plate 34- formed with notches 37, 38 and 35) adapted to cooperate with the bit 24- of the key 0. When the bolt 10 and latch 13 are in the position where the bolt 10 is in the wider portion 16 of the slot 11'. v 0., potentially unlocked, then the bit 24- is adapted to pass the notch 37 of the plate ii-and intersect the far wall of the notch 38 and move the plate to the left, Figs. 2 and '7, until said bit escapes from the notch 38 and is freed from'theplate 34: through the notched portion 39. This action takes place, if the proper cofiirdination is effected between the bits 33 of the key and notches 11 and slots 42, 4:3 and 44 of a set of tumblers 11, the proper actutation and coordination of said tumblers resulting in the movement of a projection or stump 40 secured to the plate 3-4: from position 4-2 to position 43, through intermediate position 44:. The relative arrangement and actuation of this set of tumblers is similar to that of the set of tumblers 27 heretofore described. These tumblers are also resiliently held by means of bent uvire' springs 45 bearing upon pin 46 se lllU lUF)

cured to the case 1. It is now evident that,

may be moved away from the latch 13 from which it is potentially separated, to the position shown in Fig. 2L This connection is effected by the mechanism now to be described. A rack segment 47 is formed upon the upper edge ofthe plate 34; and the same is gear connected to a pinion 48 mounted upon a pin 49 secured to the case 1. This pinion 48 meshes with a smaller pinion 50 secured to the face of a pinion 52, both of which are mounted upon a pin 51 secured to the case 1. This pinion 52 meshes with a second rack segment 53 secured to a plate 5st in turn secured to a plate 55 to one end of which also the bolt arm 9 is secured. These plates 54 and 55 are secured to the case 1 by a pin 56 and are movable thereacross and guided thereon by means of said pin and slots 57 formed in said plates 54 and 55.

Of course, the lock hereinbefore described and hereinafter claimed and shown in the accompanying drawings, may be utilized to secure any appropriate article from un warranted interference and a conventional form of such articles is indicated by the ordinal 58, Fig. 8. It is found that the lock will very conveniently lend itself to the proper securing of automobile parts.

It is evident from the accompanying drawing that the locking of the mechanism will be the reverse of that which has just been described, the sets of tumblers 41 and 27, respectively, being in such position that said locking operation results in the passage of the stumps 40 and 18, respectively,from the slots to the slots 42 and from the slots 28 to the slots 29, respectively, through the intermediate slots 44 and 30, respectively, in sequence, the relation of the notches 39, 38 and 37, and 21, 20 and 19, being such that, in sequence, the bit 24: will pass the notch 39, intersect the far wall of the notch 38,1I1OVQ'thG plate 34 to the right, then pass the notch 37 and the notch 21, intersect the far wall of the notch 20 and move the plate 18 downwardly, and then pass the notch portion 19, thewhole resulting in the movement of the bolt 10 and latch 13 to the relative positions plainly shown in Fig. l and the possible release of the key stud 6 from the look through the eye 5 and slot 5.
