To allv whom t may concern.'
Be it known that I, MAX LEVINE, a citi- Zen of Russia, residing at Brooklyn, in the county of Kings and. State of New York, have invented certain new and useful. .lmprovements in Locks, oi which the :following is a full, clear, and exact specication.
This invention relates to door locks, and has for its object to provide an improved sliding bolt lock having a `plurality of locking bolts adapted to move in unison-and adapted to `provide great resistance to attempts to force the lock.
Another object is to provide e sliding vbolt lockrin which the bolt has three stages or positions of movement, one fully retracted, another Vprojected to an intermediate stage in which vsaid boltJ may act as fa. spring lecl; or night latch, and VVanother tullyiprojected stage in which said bolt can only 'be' retracted by a positive actuation of a key or knob. A further object is to lprovide means for retainingthe bolt in its fully-retractedposition in the casing, so that the door may be L yfreely o ened Without turningthe key l'or specification, and then more specifically de-V fined inthe claims at the end-oi'l the Ldescription.

Figures 14 and 15 areside and :pla-n views, respectiyelyof the main pivoted member oi' the tumbler, andV Figure 16 is a plan View of the supple-4 mental' part lof `the tumbler, as shown in detailv in F lgures '5 yand 6, assembled with Y eo on the line 'XI- XI Y the mein tumbler membershown in"Figures 14 and 15.
The bolt 1 illustrated in detail in Figure 18 is mounted to Slide in a casing 2 being guided on posts 8 extending from the iront Wall 4t of said casing through slots in the upper and vlower portions ot the inner or -2 frame part of said boltp Said kbolt is,4 also guided inthe casing y$2/ by the 4three bolt members 6 working in slots? inthe end Wall 8 of said casingy The posts 3 have :angular portions or vblocks Se attheirxen'ds ladjacent `the-front Wall 4.0i the' casing for spacing the bolt framel trom; said Wall, as
best shown Vin Figure 2. When the bolt members 6 are' `projected `from the casing they 'are adapted to engagefslotsfin a keeper il;
9 of suitable construction and. lWhich maybe fastened tota doorjamb tby Imeans or 4screws 10, the lock casingQ being 'securedztothe door 11, Figure i2, byy screws 12' also shown lin ures 1 yand@ but omitted from/the tether yiews'forthe salient clearness.
The bolt'frzime 1 Vispreiierably `made of duced end `portion lournaledin the' knobfl-S on the vfront'w'all of thecasinjgtQ, While the other end of' sa1d1sp`1njd-le has lan engular 'notch 19alarrangedaXially thereof and engagedby a connecting lb'ar'l) carried by Y and actuated by a cylinder lock secured by bolts 21 to the rear plate or wall 22 of the casing 2 and adapted to be arranged on the outer face of the door 11, as indicated in Figure 2, the spindle 17 being thus rotatable by the key 23 of the cylinder lock 20. Said rear plate 22 is secured to the posts 3 by screws 53'.y Said spindle 17 has a radially projecting roll back 24 for actuating the bolt asv hereinafter explained. The kn-ob 18, which is ournaled in the front wall of the casing 2, also carries a roll back 25 which is adapted to actuate the bolt in dependently of the rollback 2l on the spindle 17, so that said bolt may be actuated either by the knob on the inside of the door o1' by 'the key to the cylinder lock on the outside et the door.
Both roll backs arranged in the plane ot the bolt frame 1 and are adapted to engage in notches 26 and27 in a horizontal'bar 28 ot said trame below the slot 16. Below said bar 28 there is another horizontal slot V29 in ysaid bolt frame, Y
A tumbler 30` has its main member 31 arranged between the front wall of the casing 2 and the bolt frame 1, and pivoted at one end to a stud 31 onsaid front wall. Said main portion or member of the tumbler has a laterally extending lug 32 on its tree end projectingr through the slot 29 below the bar `28 of the bolt trame. A supplemental tumbler member 33 is arranged in rear ,of
the bolt frame .1 and is secured to the main tumbler member by a screw 34; engaging said lug 32 anda superposed laterally proj ectingy Y beingurged upward to engage one ot said notches by a spring 39 attached to a'post 41.-()k on the front wall of the casing 1 and bearing at its tree end u oon the under face vand supplemental portions or members/31V Vco of the lug 32. An abutmentY or lug Ll1 on said front wall of the'casing ispositioned to limit theupward movement ofthe free end of the tumbler to the proper level for the catch or tooth 36 to engage in one of the notchesv 37 and 38. When in this nor mal position, as shown in most of the figures of the drawing,`the upper edges of the main yand 33 ot thetumblerare arranged slightly below the level ot the upper edge et the barV 28 of thebolt frame, and said tumbler members overlap the notches 26 and 27, so that Vwhen either of the rollbacks 24E or 25 is rotated about the aXis of, the spindle 17 by means of the key to the cylinder lock 20 ory sition ,of the tumbler when swung down-- ward by one Voit the roll back preparatory to moving the lock frame by engaging with one of the notches26 or 27 is indicated in dotted lines in Figure 11. f
In Figures 3, 4, and' 7 the bolt frame 1 is shown in vits intermediate position with the three bolts 6 yprojected Vtar enough to permit them to serve as a nightlatoh or spring lock.V YIt will be' no-tedvthat the rear faces or corners of the free ends of said bolt members 6 are beveled oil', as at 42, and that the notch 38 in the lower edge oi' the bar f 28 of the bolt frame is wide enough to permit said spring action of the lock bolt. Thus,
when the bolts are arranged in this intermediate position and thedoor carrying the lock is closed, the beveled ends 42 of said bolt members 6 will ride on the edge of the keeper and automatically retract said bolt Vagainst the action of the spring 14 until said members 6y register with the slots iny the keeper 9, whereupon said spring advances the bolt to engage said slots in the keeper and thereby lock the door automatically. A coiled spring 43 is preferablyV arl ranged between the post l0 and a lug 44 on the lower edge portion of the bolt frame 1 for counterbalancing the action of said bolt frame under the tension of the spring 14 which is more! spring 43. v
The bolt frame may be advanced from the position illustrated in Figure v 7 to that shownin Figure 9l by revolving either" of the roll backs, as already eXplained,said roll backs engaging the ynotch 26 in the bar 28 to effect this movement and also engaging the tumbler to release the catch 36 from the notch 38 andY seat it in the notch 37 which powerful than said f llt? is just wide enough to admit said-catch' f and consequently holds the bolt frame against reciprocation when the bolt members are in their fully advanced position,
Figure 9. It will thusbe seen that Awhen the bolt is in its fully advanced position it cannot act as a spring lock, butV must be retracted by the key or knob. l Y
. The bolt frame may be moved from Vthe vposition shown in Figure 7 to that shown in Figures 8 and 11 by revolving either of lill) tractedposition by a vertically movable latch i l5 consisting of a lug oni a plate46 having a handle or knob 17 extending through a slot 4S in the front wall of the casing 2 for actuating said latch. The plate 46 may be further guided by a stud 49 on the `tront Wall of the casing engaging in a slot 50 in said plate, as best shown in Figure 9. Said plate may also have a depending portion 51 to cover the slot 48 in the` front wia-ll of ythe casing in which the knob 47 Works. lVhen the bolt is fully retracted, the latch plate 46 may be moved downward, as shown in Figures 11 and 12, to 'bring the latch proper or lug 45 into the path of a stud or projection 52 on ythe bolt frame 1, thus retaining the latter in its fully retracted posit-ion until said latch i-s raised to the position illustrated in Figures 9 'and 10. In this Way the bolt may be fastened Wholly Within the casing 2 so that the door may be :t'reely opened from the outside as Well as from the inside Without using a key or turning the knob 18.
