Application filed November 1, 1905. Serial No. 285,465.

To all whom it may concern:

Be it known that I, CHARLES A. BERRY, of Stamford, in the county of Fairfield and State of Connecticut, have invented certain new and useful Im rovements in Combined Rim and Mortise l declare the following to be a full, clear, and

" ject exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in combined rim and mortise lock, the 0b of the invention being to provide a simple and eficient lock that can be applied to a door without any" extensive or etri mental cutting.

'A further object is to provide a lock of comparatively simple and inexpensive structure, in whichthe latch bolt may be dead locked against movement by the outside knob, or against both knobs and key, thus making it possible to deadlock the bolt against the holder of a key to the lock.

With these-and other ends in view my inventi-on consists in the parts and combinations of parts and in the details of construction that will be more fully explained and pointed out in the claims.

In theaccompanying drawings, Figure 1 is a view in elevation of the inner face of the lock showing the bolt free to be actuated by either knob or the key. Fig. 2 is a view in longitudinal section on the line w-w showing the lock applied to a door. Fig. 3 is a similar View in transverse section on the line 31- of Fig. 1. Fig. 4 is a View in front elevation. Fig. 5 is a view in elevation of the inner face of the lock showing the bolt in its keeper and the outer knob deadlocked. Fig. 6 is a view showing the knob and key mechanisms deadlocked. Fig. 7 is a view showing the latch bolt retracted by the inner knob. Fig. 8 is a perspective view of the latch bolt. Fig. 9 is a similar view of the strike plate or keeper. Fig. 10 is a view of the deadlocking mechanism for the outer knob, and Fig. 11 is a view of the meeting ends of the knob spindles. Fig. 12 is a- View in side elevation partly in section showing another form of deadlock for the latch. i 13 is a view in plan of same showing 1: e dead locking tumbler in the position it occupies when the door is open, leaving the latch bolt operative and Fig. 14

ocks; and I do hereby is a similar view showing the dead locking tumbler being raised by the outer knob.

The lock casing consists of a rectangular section 1 provided centrally at its front edge with a forwardly projecting portion 2 which latter forms the housing for the latch bolt 3. This portion 2 of the casing is provided at its outer edge with a right angled flange 4:, which latter is designed to rest within a mortise in the edge of the door, and is provided with an opening in which the latch bolt rests and moves. Connecting the flange 4.- with the sections 1 and 2 of the lock casing, are the triangular shaped ribs 5. These ribs are preferably cast integral with the plates 1 and 2, and rest on opposite sides of the bolt, and within a correspondingly shaped mortise formed in the front at the outer edge of the door.

Sections 1 and 2 of the lock casing, are provided with a depending flange 6 which extends from one end of flange 4:, around sections 2 and 1 to the other end of flange 4, as shown in Fig. 1. This flange 6, is of suilicient depth to house the lock mechan-- ism, but as the latter is simple with few overlapping parts, the casing thus formed is comparatively shallow, and when applied to a door all the mechanism of the lock rests to the outside of the inner face of the door, as clearly shown in Fig. 2.

The locking bolt is composed of the pivoted or rocking section 3, the sliding section 7 and the pivotedtongue 8. The section 3 is hollow longitudinally and open at its top to receive the pivoted tongue 8 and the sliding section 7. The tongue 8 is pivoted to the section 3 near the pivot of the latter and conforms in shape to the contour of the outer edge' of the rocking section 3 of the bolt, so that when the parts are in their normal positions, the-outer face of the tongue rests flush with the outer face of section 3. The sliding section 7 is also pivoted at 9 to the rocking section 3, and is rigidly secured at its rear end to sliding stem 10 of the locking bolt. When the bolt is in its noriual position this sliding section stands out beyond the face of the rocking section 3 as shown in Fig. 3. lVhen the locking bolt is retracted, the pivot 9 of the sliding section moving in the are of a circle concentric with the pivot of the locking bolt, causes the sliding section to move inwardly or away from the strike plate of the kee er 12, and as the bolt enters the keeper, t is sliding section is forced outward y into contact with the strike plate which tends to pull the door tight against its stop in the act of closing.

The pivoted tongue 8 is pivotally connected at 13 with the sliding plate 14. This plate 14 rests adjacent to the sliding section 7 of the locking bolt, and is provided with a bent end 15 which passes through an elongated slot 16 in the stem 10 of the bolt. It will thus be seen that when the stem 10 is drawn inwardly, the locking bolt as a whole will turn on its pivot 17 and be retracted, and when the stem is released, the parts will return to the position shown in Fig. 3.

Pivotally mounted on screw 18 secured to plate 1 of the casing, is the deadlocking lever'19, the outer end of which rests just in rear of the shoulder 20 of the stem 10 of the latch bolt. When the parts are in their normal position as shown in Fig. 3, the rear end of plate 14, (which as before explained is pivotally connected to the tongue 8) rests against shoulder 20 on the stem 10 of the bolt, and the side of the plate 14 rests flush with the side of stem 10, the two parts forming a bearing against which the toe 21 on deadlocking lever 19 slides. As the door is closed, the centrally located tongue 22 on the strike plate keeper 12, engages the pivoted tongue 8 of the latch bolt and moves same inwardly as shown in Fig. 5, thus carrying the face of plate 14 against which toe 21 of lever 19 bears, rearwardly, permitting the toe to move in behind shoulder 20 on the stem 10, and deadlock the latch bolt, and revent it from being retracted b a knife b ade or other instrument intro uced between the keeper 12 and flange 4 of the lock casing. When however the latch bolt is moved by one of the knobs or its key, the shoulder 23 on the movable .end of lever 24 engages the cam shaped end 25 of lever 19, thereby withdrawing the toe 21 of lever 19 from behind shoulder 20 and leaving the latch bolt free to be retracted.

Plate 14 connected to the pivoted tongue 8, is normally restrained against inward movement by the spring 26, while the stem 10 of the bolt is yieldingly held in its normal position by the spring 27.

Pivotally mounted on the sleeve 28 is the lever 24. This lever is cut away to receive the knob, s indles, and hubs of the cams 29 and 30 an is provided with the shoulders 23, 31 and 32. The shoulder 23, as before explained actuates the lever 19, and also engages thetoe 33 of the stem of the latch bolt, so that when said lever 24 is turned by either knob, or key the shoulder 23 enga 'ng the toe 33 retracts the bolt. The shou der 31 and' 32 of lever 24 are engaged by; the opposite ends of cams 29 and 30, so t at a the toe 45 thereof turning movement of either knob in either gigection, will turn lever 24 and retract the o t.

The knob spindle, is made in two sections 34 and 35 revolubly connected end-to end, so that either knob and its section of spindle may be turned without the other. The section 34 of the spindle passin through the door carries cam 29, while t c section 35 of the spindle which passes through lock casing carries cam 30.

Cam 29 is provided on its edge with a recess 36 in which lug 37 on the cam locking lever 38 is moved to deadlock the latch bolt against the outer knob 39. This lever 38 is pivoted at 40, and is actuated by the lug 41 on spindle 42, the latter being provided with the small finger knob 43. By turning knob 43 lug 37 can be moved into recess 36 of cam 29 and positively deadlock the latch bolt against the outer knob 39.

Lever 24 may also be actuated by a key lock 4O shown in Fig. 2. This lock is of the pin tumbler variety and its key cylinder is connected by the extension piece 41 with the rotary post 42 carried by the casing. This post is slotted at its outer end to receive the extension piece 41*, and hence necessarily turns when the lock is actuated by its key. This post is provided at its lower end with a cam 43 adapted to engage toe 23 of lever 24 for retracting the latch bolt, and with a cam 44 adapted to engage toe 45 of the slide 46. This slide is actuated by a button 47 and when moved as shown in Fig. 6, revents rotation of the post 42*, while the ower end of slide passes to the rear of lever 24, thus not only deadlocking the latch bolt against the key, but also against both knobs. With this construction, button or stop 47 may be operated when the door is open, thus dogging the operation of the knobs and key, but at the same time leaving the latch bolt free to move, so that the door may be closed, but when the door is once closed all the unlocking elements of the lock remain inoperative until the stop has been removed, thus releasing the knobs and key mechanism, so that they may again operate.

The lock casing is provided on its inner face with two integral hollow sleeves 28 and 28, preferably short tubes forced over stumps on the plate 1. These sleeves are adapted to receive the posts 48 formed integral with the escutcheon plate 49. This late fits against the outside of the door, whi ethe casing carrying the locking mechanism is secured to the inner face of the door, and the parts are secured together by the screws 50 passing through the casin into posts 48. By this arrangement the Fool: can be applied to a door of anythickness not less than the length of sleeves 28 and 28, the extension piece 41 carried by the lock, being of sufiicient length latch bolt and the keeper. In this construction instead of em loying a swinging tongue carrying a plate lihving ashoulder against which a toe on a lever abuts, I provide the sliding plate 7 resting against the flat face of the sliding section 7 of the latch bolt.

This plate 7 normally rests with its outer end flush with the outer end of the latch bolt 3, and is provided with a lip 7 which latter is designed to engage a portion of the strike plate on the keeper as the door is closed and be moved inwardly by such contact. The inner end of this plate 7 a is provided with a bent end 7 which latter passes through a cam slot 19 in the deadlockin tumbler 19. This tumbler 19 is pivoted to the stem 10 of the bolt 3, the bent end 7 passing through a slot in said stem. The tumbler 19 is forced in the direction of the knobs by the spring 19 and is provided at its free end witha shoulder 19 which latter when the door is closed and the parts in their normal position rests in line with the shoulder 20 and absolutely prevents an in ward movement of the latch bolt.

As shown in Figs. 13 and 14, the tumbler 19 is in a position to permit of a rearward movement of the latch bolt, the shoulder 19 being in a plane above the path of shoulder 20*; In Fig. 13, which represents the position of the parts when the door is open, it is shown held in unlocking position by the spring 55 which when unopposed holds the plate 7 as shown in Fig. 12, with the end 7 thereof bearing against the inclined wall of the cam slot 19*. As soon however as the door is closed, the flange 7 b of plate 7 engages the strike plate of the keeper, and forces plate 7 and its bent end 7 inwardly, and as the bent end enters the inclined portion of the cam slot, it releases the tumbler l9 thus permitting the latter to drop until its shoulder 19 is in a position to engage the shoulder 20. v

In Fig. 14 the tumbler is shown elevated by the cam 29 engaging and moving the lever 24. In this figure the cam 29 is shown in the act of turning, the toe 31 of said lever having engaged the depending shoulder 19 of deadlocking tumbler 19*. This shoulder 19 is of suflicient length to rest on toe 31 during the continued opening movement of the cam 29 and thus hold the dead locking tumbler elevated until the knob has been released.

To apply this lock to a door it is simply necessary to mortise the edge to receive the flange and triangular section of the casing,

king the latch against movement,-

and bore four holes for the sleeves, lock and knob spindles. By means of the improvements described,

the latch bolt when in its locking position,

may be deadlocked against the outer knob, or deadlocked againstboth knobs. and the key mechanism and also against any instrument introduced against the bolt between the keeper and the lock casing.

Having fully described my invention what I claim as new and desire to secure by Letters Patent, is

1. The combination with a latch bolt, key and outer knob mechanisms for retracting said bolt and means for dog ing the key and outer knob mechanisms, 0 a deadlocking tumbler pivoted to the stem of the bolt, and a sliding plate also carried by the bolt and adapted when the door is open to engage the deadlocking tumbler and hold it in an inoperative position, and to release said tumbler when the door is closed. 7

2. The combination with a latch bolt, and outer knob a device for dogging said bolt when the latter is in its locking position, and a'key mechanism actuated from the outside of the door, of deadlocking mechanism whereby the outer knob may be deadlocked, and additional deadlocking mechanism for both the key and outer knob, and means on the inside of the door for actuating said key and outer knob deadlocking mechanism.

3. The combination with a latch bolt, knobs mechanism and an independent key mechanism, of a lever common to the knobs and key mechanism for retracting the bolt and means for dogging said lever against the knobs and key mechanism, the said latch bolt when thus dogged being free to move when the door is open, so as to permit the door to be closed, without first freeing the knobs.

4. The combination with a pivoted latch bolt and its sliding stem, of a lever pivoted to and carried by said sliding stem, longitudinally sliding means carried by said bolt and actuated by engagement with the strike plate, for holding said dead locking lever in an inoperative posit-ion when the door is open, and knob actuated mechanism also engaging said dead locking lever for releasing same when the knob is turned.

5. The combination with a face or escutcheon plate having an edge flange extending wholly around same, of a latch bolt, a lever for retracting same, the said latch bolt having a loose connection with the lever whereby it may be moved independently of said lever, knob and key mechanisms engaging said lever and adapted to move same in a direction to retract the bolt and means for deadlocking the knob and key mechanisms, all of said movable parts being assembled on and carried by the escutcheon plate.

6. The combination with a face or escutcheon plate having an edge flange extending wholly around same, of a latch bolt, means for dogging same when in its locking position, lever for moving said dogging means to release the bolt, the said latch bolt having a loose connection with the lever whereby it may be moved independently of said lever, and knob and key mechanisms engaging the lever and adapted to move same in a direction to release the bolt, and means for deadlocking the knob and key mechanisms, all of said movable parts being assembled on and carried by the escutcheon plate.

7. The combination with a latch bolt and a lever for retracting the same, the said bolt being movable independently of said lever, of a key mechanism comprising a lock having a movable cylinder and means connecting the latter with the bolt retracting lever, and. dogging means for preventing the rotation of said cylinder and also for locking the lever against movement.

8. A lock comprising a casing, a latch bolt,

three bolt-operating devices, means for actuatingeach bolt-operating device independently of the others comprising knobs and a ear/nee key-o erated spindle and means for locking all oi said bolt-operating devices against movement, substantially as described.

9. A look comprising a casing, a latch bolt, three bolt-operating devices connected in operative relation with the bolt, and means for actuating each bolt-operating device 1ndependently of the others, the said actuating means comprising two knobs which are independently connected with two of the bolt-operating devices, a centrally located key-operated spindle connected with the other bolt-operating device and means for locking either one or both of the bolt-operating devices connected with the knobs or for locking both the bolt-operating devices connected with the knobs and the bolt-operating device connected with the key-operated spindle, substantially as described.
