- LOCK.

To all whom tima/y 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 Improvements in Locks; and I do4 hereby declare thel following to be a full, clear, and exact description of the in'- vention, such as will enable others skilled inI the art to which it appertains to make and use the same.

My Vinvention relates to improvements in locks designed particularly for use on doors between rooms.

For hotel and similar uses it is desirable to have a lock so arranged that adjoining rooms may be used en suite or as separate rooms and the object of theinventionisto provide a lock which may be used as an ordinary knob latch, with means operable from each vside of the door whereby it may he locked from either side. j

A A further object is to provide means whereby the llocking means can be dead locked either in thelr operative or inoperative' position. i

With these and other ends in view my invention consists in the parts and combina- `tions of-parts as will be more fully explained and pointed out in the claims.-

In the accompanying drawings, Figure 1 is a view in elevation of my improved lock, the cover plate being removed.h Fig. 2 is a view in section on line m as of Fig. 1. Fig. 3 is al view'in section on the line y--y 0f Fig. 1; and Fig. 4 isa view on the l-ine z-z of Fig. 1. v

'In the drawings, I have lshown the lock composed of an inside plate `1 an outside plate 2 and an inner case 3 containing the lock mechanism. y

The knobs 4 are mounted in the plates 1 and 2, and each knob is connected to and 'actuates a hub or roll back', which latter. in turn enga es theturnedends 6 of the tail iece 7. his tail piece is connectedv by the ink 8 with the latch bolt 9,' and is operated bythe hubs or roll backs to retractthelatc'h bolt 9, the latter being yieldingly held in itsa projected position by the spring 10.

` plane of the turned end or stop l' would `have it understood however that my improvements to -be hereinafter described are applicable to other types of locks hence I do not confine the use ofthe inven- 'tion to the type of lock shown, and above described.

Mounted in the lock case 3 above and below the latch bolt 9, are the bolts 11, each of .which is actuated by a cam hub 12 mounted in the loc'k case, one on each sideV 'of the door, as shownin Fig. 3.V Each cam hub is rotated by a thumb piece 13, one of which s mounted in the outer plate 1 and the other in the inner plate 2, and each thumb piece is provided wlth an angular -shank 14, which fits within the angular opening 16 in its respective cam hub 12. The cam 12a of each cam hub'12, vrests within a recess 17 in its bolt, the end walls of the recess, at 18 being cut away as shown, so as to form seats for the ends of the cams 12a, both when the bolts are projected and also when they are rei tracted, thus deadlocking the bolts in their two positions.

Each cam hub 12 is yieldingly held, its two. positions, as shown in Fig. l',

b a spring 19 secured to the post 20 on its bolt 11, and bearing at -its free end against the shoulder 21 formed integral with the hb 12. These springs prevent any accidental rotation of the hubs, and operate to hold the cams against their seats 18, thus deadlocking the bolt in its two positions.

Each bolt 11 is provided withan inwardly projecting lug 22, located behind and in the 23 of .plate 24 secured to the latchl tail piece7. When either bolt 11 is projected, its lug 22 rests close up to, and in the path of the stop 23 carried' by. the tail piece, and prevents the latch bolt from being retracted by. either.

A v Specification of Letters Patent. i Patented 'May 24,191.0, `Application ma June 10,1999. serial No. 501,418.

Loosely mounted on the rear end of lock' case 3 is the sliding plate 24a provided with the forwardly projecting arms 25 terminating in bent ends 26 which form deadlocking abutments.

These deadlocking abutments4 are adapted to be moved into thev` path of movement behind both bolts, when the latter are projected and thus deadlock thelatthe knob cylinder 28, connecting bar 29 and hub 30. This hub is provided with a cam 31 which is moved by the turnin of the hub 30 into position between the s oulders 32 formed by slotting the sliding plate 24a. With the parts in the posit-ion shown in Fig. 1. one bolt is locked in its projected position and the other in its retracted position, and the cam 31 is shown (in dotted lines) in a position to engage the upper shoulder :52 of plate, 24. By continuing the movement of the cam, by the key as above explained, the plate 24 will be moved upwardly thus carrying its abutments 26 up into a plane above the bolts, thus freeing the latter and permitting either bolt lto be actuated by its thumb piece. By now turning the cam 31 in the opposite direction, the sliding plate will be moved to its position to deadlock one or both bolts.

The sliding plate is held in its two positions by the bend in spring 33 engaging recesses 34 in one edge of sli ing plate 24.

IVith this lock both dead bolts may be left free to be actuated by the thumb pieces; or they may be deadlocked in the retracted position thus converting the lock into an ordinary knob latch, or they or either of them may be deadlocked in their projected positions by the key thus preventing the door from being opened except by the use of the proper key.

It is evident that many slight changes might be resorted to in the relative arrangement of parts shown and described without departing from the spirit and scope of my invention hence I would have it understood that I do not wish to confine myself to the exact construction and arrangement of parts shown and described, but,

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

1. In a lock, the combination with a latch bolt and knob mechanism for actuating same,

of a dead bolt, a cam for moving the dead bolt to its two positions and for deadlocking it in each position, means for turning the cam, and cooperating projecting members on the dead bolt and latch mechanism, whereby when the dead bolt is projected, the knob mechanism of the latch will be deadlocked.

Fig. 1, I have shown one dead bolt` :amacay i 2. `In a lock, the combination with a latch bolt, and knob mechanism for actuating same, of two dead bolts, independent means for moving each dead bolt to its two positions and for deadlocking it in each position and cooperating projecting members on the latch mechanism and both dead bolts, whereby when either bolt is projected the knob mechanism of the latch will be deadlocked.

. 3. In a lock, the combination with a latch bolt and knob mechanism for actuating same, of two dead bolts, independent means for actuating the bolts, coperating projecting members on the latch mechanism and both bolts whereby when either bolt is projected the knob mechanism of the latch will be deadlocked, and a single mechanism actuated by a key for deadlocking both bolts.

4. In a lock, the combination with latch mechanism,-of a dead bolt, means for actuating same, co rating means on the latch mechanism an bolt, whereby when the bolt is projected, the latch mechanism will be deadlocked, and key actuated mechanism carried by the lock casing for deadlocking the bolt in its two positions.

5. In a lock, the combination with latch mechanism, of two dead bolts, means for independently actuating the bolts, coperating means on the latch mechanism and both bolts whereby when either bolt is projected the latch mechanism will be deadlocked, and a single mechanism actuated by a key for deadlocking both bolts irrespective of their positions.

6. The combination with latch mechanism, of a dead bolt, means for actuating same, coperating projecting members on the latch mechanism and dead bolt whereby when the bolt is projected the latch mechanism will be deadlocked, and key actuated mechanism adapted t'o engage said dead bolt in advance of its rear end for locking same in its retracted position and also adapted to engage the bolt in rear of said first mentioned point of engagement for locking the bolt in its projected position.

7. The combination with latch mechanism, of a bolt, a cam actuated by a thumb piece for shifting said bolt, the said cam also acting as a dead lock for the bolt, a spring for yieldingly holding the cam in its two positions, and a key actuated device directly engaging the bolt for deadlocking it in its two positions.

8. The combination with latch mechanism, of two bolts, cams actuated by thumb pieces for shifting the bolts, and a key actuated deadlocking device adapted to be shifted to directly engage and 'deadlock both bolts, either in their projected or their retracted positions.
