This is a substitute application of my prior 'applicationfiled September 3, 1938, Serial No. 228,4 1. a. This inven on relates to. a novel. composite structural assembly which/may be unitarily referred" toasa so-called keyless lock operating deyicecorw means, and it has-particular reference to a manuallyv regulated and. controlled handle equipped structure susceptible of being attached was automobile door or equivalent closure in sucha way as to provide a convenient oscillatory device for actuating thelook bolt of .a conventionaldoor lock construction.

a conventional swingable automobile door and includes-a mortise lock having a casing l4 and the usual-locking-bolt 05. The device of structure shown in Figure 2 constitutes the handle mean for controlling or actuatingthislock. l -..Theimproved handle means or structure comprises two essential or" main units, that is, the manuallycontrollable handle unit It zand the mechanically. controlled shaft and lock operatingunit H. The part ll comprises a polygonal stem or shaft l8 which hasoperating connec-' tion with the lock means M as shown in Figure 1. This isprovided at the left hand end'with a; cup-like head l9 which is in efiect'a coupling socket and-provided in itsrim with an aperture or opening 23 whichfunctions as a keeper hole. The unit l6 comprisesa suitable hand'grip 2| having a shankZZ terminating in a reducedextension Elicylindrical in cross sectional shape as shown betterin Figures 5 and-6. This extension has a "longitudinal slot 24 formed therein to serve as anaadapter or receptacle for the radiallyprojectible and retractible trip lever or finger 2%. Referring to Figure 11 it will be observed that this particular element comprises a fiat strip of metal constructed to fit in the adapter slot 25 andto project beyond the right hand open end thereof as illustrated in Figure 3., It

has a disk-like head 26 at one end provided with an. elongatedslotil slidably fulcrumedin-place as indicated at 28 in Figure 3. The free swingable end thereof indicated at 29 constitutes the finger portion and fits into a kerf 30 in a coupling or keeper pin 3|. This is in effect a plunger and is mounted in a suitable guideway in the extension 23. That is to say, the pin is slidable at right angles to the longitudinal dimension of the extension 23 and this sliding movement is effected by the action of the trip lever 25. When projected the pin 3| is engaged in the socket or aperture 29 which as before stated functions as a keeper and this constitutes the means for coupling the two parts It and I! together for rotation in unison. Incidentally when the parts are assembled, it is evident that the extension 23 projects telescopically and rotatably into the cup or socket |9. Referring again to Figure 11, I call attention to the features 32 which may be conveniently described as longitudinally spaced detents. Then referring to Figure 3, I call attention to the flat spring 33 located in the slot 24 and interposed between the bottom of the slot and the adjacent edge portion of the trip lever 25. It will be noted that one end portion of the spring is formed into a curl or coil as at 34 where it surrounds the head 23 and is properly anchored in place.

The parts l6 and I! are swivelly joined together as indicated at 35. This is simple collar and pin arrangement and includes a protective shell 35 suitably fastened on the head Hi. This serves to cover the features 20 and 3| to render them inaccessible.

Novel combination tumbler means is provided to keep the parts 25 and 3| normally retracted or retracted when occasion demands so that no matter how much the handle 2| is turned this will have no effect on the door lock bolt l5. This is a so-called combination means and the essential features thereof are shown in Figure 4. The numeral 31 for example designates what may be described as the master tumbler or annulus which rotatably surrounds the extension 23. This is in abutting relation with the shank 22 and the enlarged portion thereof is knurled and formed into a finger grip as indicated at 39. The adjacent reduced portion 39 is calibrated or graduated to serve as a rotary indicator for coaction with the fixed or relatively fixed index 46 as shown in Figure 1. The companion tumblers or rings are indicated by the numerals 4| and 42 respectively.

These tumblers have coacting detector and driving lugs 43 properly located for progressive and collective coordination. On the inner periphery of these tumblers I provide registerable notches 3211, these being adapted to receive the detents 32 when projected by the spring 33. Located between the tumblers are spacing washers M held against rotation by keying projections 45. All of these parts when assembled are housed within a shield or sleeve 46 as shown in Figure 1 which is attached to the door by a suitable attachin flange 41. This protects and encloses the vital mechanism of the construction.

Manifestly, when the notches 32a in the various tumblers are out of alignment with each other and are out of registry with the longitudinal open edge of the slot 24 they serve to cam the trip lever 25 into the slot 24 holding it in this retracted state against the tension of the spring 33. At the same time the plunger or pin 3| is held retracted and naturally there is an idling coupling between the two parts i6 and IT so that rotation of the handle 2| does not effect a movement of the shaft or stem [8. This is the unlocked state of the structure. When it is desired to lock the parts l6 and IT together to rotate as a unit it is obviously necessary to liberate the trip lever so that its complemental spring serves to project coupling pin 3| into the keeper socket 20. To do this it is necessary to bring all of the notches 32a in the respective tumblers 31, 4| and 42 into alignment or registry with the detents 32. By referring to the dialing or indicator means it is possible to turn the master tumbler 31 in such a way as to pick up and turn the next adjacent tumbler so that it in turn actuates the final tumbler 42 and by a proper combination of turn or rotary adjustment, known only to the user of the lock, it becomes possible to register the notches 32a as shown in Figures 3 and 4. Obviously, the minute that these features come into registry with one another this liberates the depressed spring projected lever 25. In so doing, the detents literally jump into the notches 32a and this allows the plunger or pin 3| to project itself into the keeper hole 29, Naturally, this pin couples the two parts it and I! so that they may rotate in unison to positively control the movement of the locking bolt I5. The gist of the invention, as I see it, has to do with the adoption and use of the companion parts l5 and I1, these being swivelly joined together, one part I? being provided with a keeper 20 and the other part IS with a spring projected trip controlled coupling pin 3| which under predetermined conditions and controlled by the tumbler means is liberated to join the two parts I6 and I1 together for rotation in unison. Novelty is also predicated upon the coordination existing between the manually controlled tumbler mechanism mechanically coordinated with the detent elements 32 on the spring pressed finger or lever 25, whereby it is permissible to positively depress or liberate the trip lever whenever occasion demands. Consequently, the mechanism is under the complete control of the authorized user and obviates the need of having a key, as is customary.

It is thought that persons skilled in the art to which the invention relates will be able to obtain a clear understanding of the invention after considering the description in connection with the drawings. Therefore, a more lengthy description is regarded as unnecessary.
