comiNATIoNLA'rcH-Loex.

To all wliom it may concern! delphia, Pennsylvania, have invented certain Improvements in CombinationLatch- Locks, of which the following is a Aspecification.

My invention relates tothat class of ,comiV l bination locks inv which the retraction of the bolt is eiected-by the knob through the medium of the tumblers and bolt-operating mechanism, and the projection of the bolt is dueto the action ofa spring or springs, the objects of my invention beingto provide for the automatic ejection of the dog "iii-om the notches of the tumblers and the dispersal. of thelatter when thelbolt is projected' byV the action ofthe spring, and to provide, in a box or chest lock, for they automaticprojection of the bolt, the ejection of the dog.` fromV the notches of the tumblers, and the dispersal of the latter when thelid is closed. These objects I attain in the'manner hereinafter set "forth, reference being had to the" accompanying drawings, 1n which Figure 1 isa transverse sectionon the 'line a-a, Fig. 3, but on an enlarged -scale, and

be governed by the, sense ofsight. The lock can, however, also be operated by the .sense ofy hearing or the sense of touch, the knob 4 beingmovable axially in the barrel 3,

`and the knob spindle dbeing also free to slide axially 'in .a Atubulary h'ub 7 projecting v Letinto suitablerecessesin the inner face A of the knob @are afpair of balls 9, or in place of theV same, fixed lugs or4 studs may be formed on or secured to the inner face of the knob. Formed in or rigidly secured to the interior of the barrel V3 is an annular plate 3a, in which are. formed a seriesof conntersunk openings or depressions 10,

correspondin in number with the figures or numbers of e dial when the latter is employed, whereby, when the knob lV isi-moved lnwardly, the balls 9 will engage these openings or depressions and the proper movements of the knob to effect the desired adjustment of-the tumblers ofthe lock -will be indicated both to the sense of hearing and to that of touch, as said balls 9, on the rotation of the knob enter the 'openings or depressions 10 in succession and produce a clicking sound,

so ,that the lock can be operated in the dark as, well` as when a dialA is visible to the operator. These features ofthe lock,how

ever, constituteno part of my present invention, being shown, described and claimed in y prior application, No. 316,511, dated May 12,1906. l

'A spring 6 interposed between the annular .plate: 'a and a disk'14 on the knob spindle 5 tends to'nrmally maintain the balls 9 in en` gagement with'the countersunk depressions or openings'lQ, but slight longitudinal movement of the knob spindle, restricted by the. headof a screwf13 at the inner end of said spindle, permits such outward movement of the knob as to eiiect withdrawal of the balls 9 from the openings 10, and the lockcan then -be' operated by sight alone.

The disk 1li-'engages a reduced or'flattened portion of the knob spindle 5, and it is there fore compelled to turn with the latter, and thus constitutes a driving disk for the tumblers. "f Y The driving disk 14 has a series of-slots 15 anda series ofnotches 16, one for each slot, and with any of the slots '15 may engage a pin n 17 projectin from a supplementary driving disk 19, willich is mounted so as to be free to turn on the htib 7 of the' face plate. Between the main and supplementary driving .disks are interposed tumblers 20, each ot which has a peripheral notch 22 and also al segmental slot or slots 21 for-'thereception of the driving pin 17, the length of each slot and the relation of a peripheral notch thereto determining the adjustment of the dierent tumblers necessary in order to bring their notches into line in opening the lock. The supplementary driving disk 19 also has a peripheral notch 22, and therefore acts as a tumbler in the same manner as the tumblers 20. These tumblers, like the disk 19, are free to turn on thehub 7, but are prevented, by washers 23, from imparting motion one to another except through the medium of the driving pin 17, the washers being interposed between the successive tumblers and between the first tumbler and the supplementary driving disk 19, and being prevented from rotating by reason'of the engagement of Slotted lugs 24 thereon with a l-ug 25 projecting inwardly from the face plate 1.

Between the supplementary driving disk 19 and the face plate of the lock is interposed a bolt thrower 26, which can turn on the hub 7 and is' provided with projecting teeth 27 and 28 forengagement with the bolt plate 31, which has in the present instance twobolt lugs 32 and is guided between a ange of the lock plate 1 and 'a slotted rib 34 project` l ving from the inner face of the same;Y the'bolt plate being intended to lbe movedY in' one direction by the bolt thrower 26, and in the opposite direction by a spring 29 connected at one end to a stud 30 on the bolt plate 31.l

and at the other end to a the face plate of the lock.

Pivoted to a pin 35 on the bolt thrower 26 is? a lever 36 provided with a dog 37, said lever being acted upon by a spring 38 in such manner that the dog 37 has a normal tendency to move inwardly or toward the axis ofthe knob spindle. A On a pin40 in. the lock case swings a hooked arm 41 which partially embraces the hub 7, as shown in Fa'g. 6, and is normally 'maintained in contact with said hub by means 'of a spring 42.

A pin 43 on the bolt plate 31 serves as a pivot for a trigger 44, whose free end, when post 30, secured to the lock is open, is caused, by the action of a spring 45, to project through a slot 4G in the guide rib 34, as shown in Figs. 3 and G, the end of the trigger thus retaining the bolt plate 31 in the unlocked position againstthe action of the spring 29. `When, however, the lid of the box or chest is closed, one of the hasps strikes the projecting end of the trigger '44, and depresses the latter to suchan extent that lit is disengaged from the outer wall of the slot .46 of the guide rib 34 and fails to longer retain the bolt plate in .the open position, the spring 29 then moving the holt plate from the position shown in Fig. il tothat shown in Fig. 2, thereby eil'ecting the ejection of the dog from the notchesl of the tumblers and the dispersal ol the latter as hereinafter set forth.

'Vhen the lock is locked and the bolt plate `3l projected the parts occupy the relation shown in Fig. 2, the vinner end of the dog 37 resting uponthe peripheries of the tumblers and driving disks, but when by proper manipulation of the knob 4 the notches 22 of the tumblers and a notch 1G oiE the driving disk have been brought into line with each otherand with the inner end otthe dog 37, the latter will, by the action et a spring 38, be caused to enter said notches, and further movement of the driving d isk will therefore be imparted to the dog and thence to the bolt. thrower 26 which carries the same, and consequently to the bolt plate 31 so as to retract the bolt lugs 32, as shown in Fig. 3. l

Then the dog 37 enters the notches ot the driving disk and tumblers, it is brought in front of the inner end of the arm 41, as shown in Fig, S, andas the dog is moved forwardly it carries said-arm 4l with it, the arm swinging on its pin 4() until, because oi the different arcs of travel of the arm and dog, they clear each other, whereupon the arm is immediately restored to its normal position by the action ol the spring l2, as shown in ltig. 3, thus bringing under the dog 37 the outer face ot the arm -ll which is jnclined in respect to the are ol'l travel ot the inner end of said dog 37 when the latter .is in engagement with the notches ot the `thrower, the inner end of the dog 37, will ride on the inclined face of the arm 41 and will be forced by the latter ',out of the notches ot' the driving disk and tumblers, and the latter will, by their momentum, be dispersed or disarranged to such an extent as to carry their notches outof line with one another, and thus compel a readjustiment of the tumblers through the medimn of the knob bcfore the lock can be again opened.

In Fig. S -I have illustrated the application of my invention to amordinary l'orm of latch lock having a beveled bolt 32, the lock plate 31l having a slot 3l" whereby it is guided on lche pin 40 upon which'the arm 41 is mounted, the action of the lock in other respects being the same as that of the lock which l have described at length in the preceding portion ofi this specification. i

I claim l. In a spring lock, the l'omhination of a bolt, notched tumblers, a dog engaging the same and remaining. in engagement therewith when the bolt is retracted, and automatic means independent of the tumblers and acting directly upon the dog to effect ejectment of the same and permit dispersal of the tumbler-s by rotation of the same when the bolt is projected.

2. In a spring lock, the combination of a bolt, notched tumblcrs, a dog engaging the same and remaining in engagement therewith when the bolt is retracted, a bolt thrower carrying said dog,'and means independent of the tumblers 'and acting directly upon the dog to effect automatic ejectment of the same and permit dispersalof the tumblers by rotation of the same when the bolt is projected.

In a spring lock, the combination of a "bolt, notched tumblers, a dog for engaging the same, anda dog-engaging device which is moved out of the way by the dog in the opening movement of the lock and engages and ejects said dog when the bglt is 'projected. y

et. In a spring lock, the combination of a bolt, notched tumblers, a dog for engaging the same, and a pivoted and spring-actuated dog-ejectorv which is mgoved out of the Way by the dog in opening the lock, and acts upon said dog to eject the same from the notches of the tumblers when the bolt is projected.

5;'In a springlock thev combination of notchedtumblers, a dog for engaging the same, and a dog-engaging device having a free end normally projecting into the path .of the dog but swinging in a plane eccentric to said path, whereby it is automatically freed from engagement with the dog as the latter moves forward, said free end of the ejector having a cam formation which acts lupon the dog to eject the same from the notches of the tumblers as it moves backward.

Intestimony whereof, I have signed my naine to this specification, in the presence of two subscribing witnesses.
