Specification of Letters Patent,

Patented Dec. 14, 1909. Divided and this application f 'ied March 24,

Serial No. 485,446.

To all whom it may concern:

Be it known that I, RnINHoLD Sonoma., of Stamford. in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Locks; and l do hereby declare the following to be a full, clear, and exact description vof the' invention. such as will enable others skilled in the art to which appertains to make and use the same.

My invention relates to an improvement in locks, and is a division of application No. 449,317. tiled b v me lAugust 19th, 1908.

The object of this invention is to provide improved means for indicating both on the inside and outside, the condition of the lock, and it consists in the parts and combination ot' parts as will be more fully described and pointed out in the claims.

ln the accompanying drawings, Figure 1 is a View ot' 'the lock from the outer side showing two ke'v cylinders and an indicator. Fig. 2 is a similar view from the innerl side showing the thumb piece by which the latch bolt is locked from the inside. Fig. 3 is a vieuv ot' the lock with the cover plate removed. showing thc auxiliary bolt retracted and the latch bolt unlocked and free to be retracted by the knob or by either theupper or lower cylinder lock. Fig. 4 is a similar view showing the parts in their positions when locked from the inside by the thumb piece the Jface plate of the lock case and its outer escutcheon being removed and shown to the right of the lock case. Fig. 5 is a view showing the slide 45 in its intermediate position, and Fig.4 6 is a view inl section of the outside indicator.

1 represents a lock case, 2 the latch bolt and the auxiliary bolt, the latch bolt and the auxiliary bolts being forced outwardly by syn-ings in the ordinary manner.l

4 is a lever actuated by the hub or roll back 5, through which the s indle 6 of the knob 7 passes, the free end oiP lever 4 engaging cross head 8 'on the inner end of the stem 9 of the latch bolt.

10 is a deadlocking. lever mounted on the This lever is 14 and l5, the first of which lies in the path of cross head 16 on the stem 17 of the auX- iliary bolt 3,'and when the bolt is projected,

is engaged by said cross head and' bolts deadlocking member 13 of lever 10 out of the path of bolt 2, thus leaving the latter free to be forced'inwardly as the door is closed In the operation of thelock, the auxiliary bolt 3 1s adapted to engage the strike plate and be held retracted when the door is closed, and when in such retracted position, it releases 'thefdeadlocking `lever 10, thus permitting the spring 18 to turn the latter in a direction to bring the end of the arm 13 in rear of the bolt 2, (which when the door is closed, 'has entered its seat in the strike plate) thus deadlocking the bolt against retraction, by a. thin instrument in sei-ted against the bevel face of the bolt intermediate the face and strike plates of the lock.

19 is the actuating lever of the upper cyl-- inderV lock. This lever is pivotally mounted on the pin 20,and is provided with a spring 21 which tends to hold shoulder 22 ot the lever 1.() away from the cross head S of bolt 2, its movement away from said crosshead, being limited by the fixed stop 23.

Mounted on pin 1l, and resting in front of and against the deadlocking lever 10, is the cam lever 24, provided at its free c nd, on its inner side with a lug 25 resting 1n contact With the inclined face 26 at the free end ot bolt actuating lever 19, and at its free end, on its outer side With an integral lug 24a, adapted to be engaged by the cam 27 on the inner end of the revolving plug 28 ot' the upper cyligpder lock 29a, hence when the plug 28 is'turiied by its proper key,..its cam 27 engages lug 24, and turns cam lever 24, thus moving its 1ug"2 in contact Wlth the inclined face 26 of lefver This engagement of the lever'24 withlever 19, turns the latter on its pivot 20 in a ,direction to cause its shoulder 22 to engage and move the cross head 8 rearwardly in a directiony to retract bolt2.

Mounted on pin 11, in contact With and in front of cam lever 24, is the auxiliary deadlocking lever 29. This lever 29 is provided with three arms or members, the arm 30 of which is provided With a pintle 31 carrying one end'of the connecting bar 32, the opposite end of said bar being pivotally connected to pintle 33 on cam lever 34, pivoted near the'lower end of the lock case 1,- and in a position where itsfree end 35 may be engaged, and the lever moved,r by the cani 36 carried by the 'plug 3T of the lower cylinder lock 88. Lever 29 is also provided with a lug 40, which rests above and in contact with the upper edge of cam lever 24.

The upper cylinder lock 29 together with the lower cylinder lock 38, are accessible only from the outside of the door, the upper lock being operable by one or a plurality ot' keys,

y such as guests or change key and anV emergency key, and the lower lock being oper able by one or a plurality of keys, such a's maids and master keys.

From the foregoing it will be seen that the bolt Q may be retracted by the lower lock 38 through lever '34, bar 32, auxiliary deadlocking lever 29, lug 40, can". lever 24 and bolt'actuating lever 1 9, While `the bolt 2 may be retracted by the upper lock through cam lever 24 and bolt actuating lever 19. When the bolt 2 is not deadlocked, it may also be retracted by the knobs from either side of the door. i

When the door is closed, and the bolt deadlocked by the lever 10, the latter must, in order to release the bolt, be moved out of the path of the latter by'mechanism actuated by the thumb piece. from the inside, or by the keys of the cylinder locks 29a or 38, from the outside. This is accomplished by the key locks from the outside 'through the arm 15, on lever 10, normally 'resting in the ath of the free end of the bolt actuating ever 19. This lever 19 as previously exlained, is actuated by both locks, and as it 1s turned its free end engaging shoulder 41 on arm 15 of lever 10, turns the latter in a direction to elevate the deadlockiug arm 13, and holds it in such position until the lever 19 has been released.

f The bolt is actuated from the inside by the knob, and is locked from the inside by the thumbpiece 42. This thumb piece is conneeted to the hub 43, to which is pivotally connected one end of the link 44, the opposite end of said link being connected to the slide 45. This slide 45 is mounted in the lock case above the bolt Qand is adapted to be moved toward and away vfrom the face plate 46 of the lock, by the thumbr piece 42, and is yieldingly held in its several positions 48 formed lin the lock case near the top thereof. There are three notches 4S in the lock case, and when the toothed end ol the spring 47 is in thel notch 't'wthest removed from the face plate 46, the arm 13 of deadlocking' lever 10, will be held out of the path of the bolt by the engagement oit' the slide 45 with the arm ll o the deadlocking lever 10 thus holding arm 13 of the latter 'out ot' the path or bolt 2 and permitting the latter to be freely actuated by the knob from either side olthe door; when the toothed end of nearestthe face plate of the-lock, which is the position into which the parts are moved by the thumb piece when lockingv the door from the inside, )the shoulder 50, to be hereinafter referred to, on the slide 45 rests in 4the path of armrl on lever 29 thus deadlocking the latter and preventing the bolt from being actuated lby the lower cylinder lock, which a:- previously explained, `is adapted to be actuated by the inside key and by a master key. T his last position described, represents the position of the parts when the guest is in his room and the door looked.

lVhcn the door is closed and the slide 45 is in its position against the face plate 46 ot' The lock, the bolt n'ill vbe deadlocked against the knobs and also against the lower lock 3S, but may be opened by the guests key or emergency key in the upper lock. When the door is open. the auxiliary bolt., as before explained, holds the deadlocking' arm 13 ot' lever l0, out ot' the path of the bolt lt. Y

when the door is open. the slide 45 be moved by thumb piece 4Q, either through accident or design, into its position adjacent the face plate 46, and the door be thef-lfciosed, the direct `pressure oi the head of the bolt against the slide, will overcome the friction o'l the spring 4T and forcibly push the slide. rearwardly to its innermost position. The slide in its inward movement, makes contact with the short arm 14 of deadlockingl lever l0, thus turning the latter vin a. direction to carry its arm 13 out of the path ot' the bolt 2 so that When the door reaches its closed position, the bolt Will be unlocked or free to be retracted by 'the knob.

rlhe bolt is locked from the inside solely by the thumb piece and is locked from the outside 'by turning the plug of either cylinder lock in one' direction, and is unlocked loo from the outside bv turning the plug of the lock in the opposite direction.

vlt will be seen that when the door is closed and the slide 45 is in its position farthest removed from the face plate -l-6."the deadlockingl arm 12:3 of the deadlocking lever 10 will be held out of the path of the bolt 2, by the venga gement of the slide 45 with the arm llt ot the desn'llockinglever 1'0, thus leaving' the bolt 2 freel to be actuated by the knobs. lf the door be closed with the parts in the position last described, and the guests, maid s or other key be inserted and turned to the left, a Awhole revolution, or in the direction opposite to that which it turned to unlock the lock, the arln 29" ot the auxiliary deadloclring lever 2t), shifts the slide 45 toward face plate 4G in center notch. a distance. sutticientto release the arm 14 and thus per- 5 mit the deadloclting lever to turn until, its arm 13 is in a position to deadlock the bolt. When the door is locked from `the inside by the thumb piece 4Q. the shoulder 50 on the slide forms an abutment for the arm 51 on they auxiliary deadloeking lever 2S). and

"a's tlilelower lock 38 transmits motion to bolt actuating lever through lever Etat, bar R2. .auxiliary deadloclting lever Q9, and cam l .ile've'r stinthe order namethit follows that 15 if theauiili'aiy deadlocking lever be dogged bythelid'e plate, the bolt cannot be retracti'ed byfthe lower lock, but istree to be retracted by an emergency key or the guests key introduced in the `upper lock, which opcrates directly through cam lever 24 and bolt -retracting'lever 19. f

JA For.- the purpose otl indicating on the ininthe-outer escutcheon plate :36 above the npper lock-29. This plug has an angular outer end' which rests in ahcorrespondingly shaped opening in escutchepn plate 56, the shape ot the vplug' and the opening in the escutcheon plate, preventing the plug from rotating i 4o `aattfer the parts have been assembled. The

- plug passes tlii` 'igh the door in rear ot the escutelzeon. 'plate f5.6, and its inner screw ,threaded eind` is vscrewed into the plunger G1 mounted in the sleeve 56a carried by, andv 4.5` projecting inwardly from the loclrjcase. i -This plunger (3l 'is provided at itsinner end with a head 57 against which one end, ot the spring bears, the spring tending yto normally hold the .plug retracted with its 5o outer end approximately tlush with the outer face ot the escutcheon plate jt'whieh is its normal position when the door is not locked. The slide is provided with a tail piece 55) provided at itsI rear end with a4 cam G0 adapted when'the slide 45 is moved to its position adjacent to the t'aee plate 4G ot the lock to engage the plunger ol and move the latter outwardly causing the. outer end ot plug 55 to project. beyond the escutcheon 6o plate, and indicate by its position., which can be seen by the cha mbermaid or other person on the outside, that the room is locked from the inside.

By making the indicator ot two parts eX- tensible by reason of their threaded connection, the indicator may be adjusted as to length so as to be accurately fitted to doors ot ditl'erent. thiekiiesses.

1When the door is locked from the outside by a key. the slide l5 is only pushed one tooth, which is not sufiieient to cause the cam toerigagc the plunger. consequently when the indicating plug isv in. and the door locked,'it indicates at once to the maid that the roomis empty.

It is evident that eliangesin the construe tion and relative arrangement of the several parts might. be made without avoiding my invention and hence I would have it. understood that I do not restrict myself to the particular construction and arrangement' of parts show-n and described, but- Having fully described my invention what I claim as new and desire to secure by Letters-Patent, i t-f 1.
