Patented July 10, 191'?.
Application filed April 14, 1917. Serial No. 161,999.
To all whom t may concern:
Be it known that I, HENRY G. VOIGHT, of
locks and it pertains more especially to locks of the type in which a latchbolt is retractable from opposite sides of the door by separate knobs or other manually operable devices, there being suitable stopwork associated with the hub of the outer knob so that the latter may be dogged to prevent opening of the door from the outside through the retraction of the latch.
In some instances locks of this character have been attacked by throwing 'olf the stopwork or night-latch mechanism. by a wire or like instrument inserted between the jamb and the face plate, and it has been proposed to remedy this objection by providing an auxiliary dogging means for the outer hub which is operated automatically on the closing of the door, when the ordinary stopwork is in the operative position, to dog the outer hub independently of said stopwork so that the door cannot be opened by a burglar even if the regular stopwork is attacked and operated in the manner A above mentioned.
One of the primary objects ofthe present invention is to furnish a lock, of the general character last stated, in which the automatic dogging mechanism for the outer hub or its equivalent is especially simple, reliable and easy to manufacture and assemble.
A still further object of the invention is to provide a lock, of the character stated, in which the stopwork is provided with means for positively and automatically locking the automatic hub dogging device in its inoperative position when the stopwork is thrown ofi during the time that the door is open.
To these and other ends the invention consists in the novel features and combinations of parts to be hereinafter described and Claimed shown).
In the accompanying drawing,
Figure 1 is an elevation of a mortise lock embodying the invention, with the cap plate removed, showing the stopwork dogging the outer hub, the door being open.
Fig. 2 is a view similar to Fig. 1 but showing the door closed and the outer hub dogged by the automatic dogging device.
Fig. 3 is a view showing the ordinary stopwork released, with the door closed, the automatic dogging device for the outer hub remaining, however, in the operative position.
Fig. 4 is a view showing the automatic dogging lever for the outer hub, locked in the inoperative position by the stopwork.
Fig. 5 is a detail reverse view of the lower part of the lock, showing the dogging slide, hubs, etc., and
Fig. 6 is a detail section on line 6-6 of Fig. 1. t
Referring to the drawings, 20 is a mor tise lock case having `the customary latchbolt 21, the shank or stem 22 of which is provided at the rear end with a cross head 23 engaged, in the ordinary manner, with the usual knob-actuated retracting yoke 24:. The yoke 24: may be actuated by means of an outer hub 25 and an inner hub 26 connected with the usual knob spindles (not In the form shown, the latchbolt 21 may be actuated by means of a lever 27 engaged with a crosshead 23, and adapted to be operated by suitable key mechanism which it is not necessary to illustrate The outer knob may be dogged by night-latch mechanism or stopwork of the usual type coperating with the outer hub 25 and comprising the customary dogging slide 28,
walking beam 29, and releasing slide 30, the slides 28 and 30 being provided with the usual heads or buttons projecting through openings in the face plate s0 that the stopwork can be actuated from the lock front in the ordinary way. When the door is closed, the latchbolt 21 is automatically dogged in the customary manner by means of a dogging or guarding lever 31 controlled by a guard bolt or controller bolt 32 .projecting through the face plate and y v...so
adapted to be pressed inward by contact with the strike 33, as shown in Fig. 2. As the controller bolt is forced inward by contact with the strike, a lug 3.4, 4carried at the y 5 lower fend of-a,y depending plate 35 on the shank of the spring-pressed controller bolt, is moved rearwardly to permit the clogging lever 31 to be'swung into ldogging position, relativ-'ely toy the latchbolt, by lmeans of 'its ging lever at such a point as to hold it up wou-tof the path-of the latohbolt head.
All of the parts so far :described-are old and wellknown, and form in themselves no part of theipresentdnverrtion.
Y -The :automatic.fdoggingnneansV for i the -outerl hub 25 comprises, preferably, an-y elbow lever 537 pivoted1 on= a post 38= and A'carrying at itselowerf end a klug or :extension v'39 vadaptedto enga-ge the-notch 40 vwhich is :engaged bythe. dogging *slidel 28. rEhe V'lever 37 overlies fthe slide 28, the yoke, f'the :latch- Yhelm-randth'edogging lever 31,:and thelug 39 liescloseto the inner endfof -thedogging slide 28 in- :such relation -to 'the -outer hub .that the *latter can-'berdogged:simultaneously by the slide and by the lever, both of which fmayextend iinto;the .notehf40. A spring 41 `carriedby. lthe ylever reacts against :the -post 42 f (which, incidentally, is the; pvot post for the .deggingf lever) and `tends to hold Ythe lever4 37 :in :the :notch of the outer -hub. The lever is held out of thenotclnhowever, 5whenitheedoor.isaopen by the controllerbolt 32, the lug 34 of which underlies the upper `.end portion of ,the :lever-'37 Land controls it .in :much the .same manner .that :the -bolt dog- .gin-gfflever isicontrolled. For (this purpose fthe.' upper rend; 'portionof lever-37 iis provided -A'with shoulder 37a `whichaengages .the upper surface of lug -34 Awhen/the door is open tofih'old-:up: the ,uppervr end oflthe `lever ysothat .its lower end will be `:freefof rthe hub-25. When,.fhowever, the door is closedyand the controller bolt -is thrust .inj ward, itheA lug 34-moves 'into -arecess 37b and consequently thewspring 41 .lis permitted -`Etofact,thereby forcing the lug 39..into the .notch and' doggingtheouter hub against rotation i Y '-.The-npperend 'offlever 37 is, vprovided .withna :small :notch-44,' adapted to be .en-

Therefore'lthe burglar Acannot gain access to the room, or house, even if he succeeds in throwing ofi' the stopwork.
When the door is open the dogging'lever 37 -`stands-'out of the notch-in thel'ou-ter'hub, f owing-tothefprovision of the controller bolt,
