Be it known that l, llriNui' (i. Voioii'r, citizen of the United States, residing at New Britain, county of Hartford, Coiiiieetieut, have invented certain new and useful [Inproveineiits in (orridor Door Locks, of which the following" is a tail, elear, and exact description.

This invention relates to improvements in looks, and is particularly .2 .ehil in connection with corridor-doors for hotels and the like. In such looks it is d looking deviee for the inner side of the door, which device when thrown into action makes it ii'npossible to operate the latch-bolt by means of anything but a s ieeial key, called a giai'id mastenkey, which Will operate both the bolt-actu dead-loeking ineaiis. By this arrangement the guest may have one key adapted ate a single look from the outside of the door, but not the deadlock. The floor attendant may have a master-key adapted to operate the bolt-retracting means in any group of looks, but not any lock which has been deadlocked from the inner side of the door. The proprietor may have a third key, which is termed the grand ii'iasterl :ey, by which he may unlock any door on any floor wl'iether it is deaddocked or not. The construction is also such that when the door is dead-locked no key but the grand inastor-l-tey will have any eil'cct whatever upon any of the locks, and any one atten'i 'iting to use a key excepting said grand inastenkey may insert the same in the keyhole and turn it freely without meeting any obstruction. This relieves all strain on the look mechanism and all danger of breaking a key. These objects and others are attained, as will be apparent to mechanics skilled in the art from a reading of the following description.

In this construction the outer side of the lock is l E l l i F l l l esilatie to have a deadating means, as well as the 3 side of the door only, so tl l l to oper- I opened from the outer side by the use of a Specification of Letters Patent.

By this means the dogging device may be moved into and out of action.

12 is a lever pivutally carried by the slide H. One end ol' this lever engages the latch-bolt 3, while the other end, (when the slide is in l the position shown in Fig, ll is within the range of action of a cam Iii, operated by a key inserted in the luck 'l'rom the outer side of the door. When, however, the slide is in the position SllUWll in Fig. 2, this end ol the lever 12 will be out of the range of action of the cam 15' \Vhen the grand mastenkey is introduced in the lock 12 from the outside and turned, the cam 13 will on the lirst turn lift the tumbler 9 and then shift the slide S to the position shown in l ig. 1. A further partial turn ill cause the can] 13 to lift the lever 12 and draw the bolt 3 'lhus in all instances the lock may be operated from the outside by the use of a grand niaster-lwy, a 'l'eature of great value, particularly in the case of aeeident to the occupant ol' a room who has previously dead-loclnwl the door and who needs assistance Now as to the use of the change-key and master-key. These keys are adapted to lock 1. \Vhen the room is cn'ipty, the parts stand as in Fig. 1.. When in this state, the latchbolt may be retracted by either of said keys.

14 is a lever pivoted at 14. (inc end of this 1e ver is connected ith slide 8, so that said lever will be rocked as said slide moved t and fro 14" is a bell-crank lever pivoted ta the lever 14v 14 a nose on 14", which nose bears against lever 7. 14 is one arm of said bell-wrank, which arm stands elevated or depressed according to the position of the dogging-slide Now it a user of a room en ters the same and dead-locks the slide he thereby sets the parts as shown in Fig. The arm 14 is thereby moved out of the range of action of cam. 15 on lock 1.. Hence at such times the latch-bolt I} cannot be retracted by any key inserted in said lock. At such a time only the holderoi a grand mas ter-key can get in. Such a key, as above described, is adapted t) lock 2 and by the use of same the dogging-slide may be iirst retracted and then the latclvbolt.

hat is claimed is-- 1. In a lock, a latch-bolt, a'deaddoctnng dGViCG,"TTlBILl1S to actuate said dead-locking device from the inner side of the lock, means independent of the first and outside of the lock to actuate said dead-locking device and retract the bolt, and additional and independent means for retracting the bolt from ot' actuating the dead-locking device, and a hnul -contr\illed spindle for retracting the latch-bolt independently of either of the'lirst mentioned means 3. In a lack, a latch-bolt, a dead-lock therefor, means to actuate said dead-lool from the inside ot a door, and two independent key- 'ontrnlled means for actuating the latch-bolt from the outside oi the door, one of i said keywontrolled means cooperating with the deadlock whereby the latter may be ast oil preparatory to retracting: the latch bolt by the said means.

1. in a lock, a latch-bolt, a dead-lock therefor, means to actuate said dead-lock from the inside of a door, two independent l ey-eontrolled means or actuating the latchbolt from the outside of the door, one of said key controlled means coi'iperating with the dead-lock whereby the latter may be retracte ed preparatory to retracting the latch-bolt by the same means and a lilli'llJ-CUIIU'OllECl spindle accessible tron: one side of the door and operatively connected with the latchbolt.

5. in a lock, a lateleholt, a knob-spindle opmatively connected with the latch-bolt, a dead-locking device for said bolt, means at the inside of the door for operating the same, and two independentlykeycontralled means on the outside of the d nor for operating said latch, one of said lastsmentioned means also operating the dead-locking device.

6, In a lock, a latch-bolt, a dead-lock therefor, means for operating said deaddock from the inside of the door and including a roll-back onerahle from the outer side of the door only tor operating said dead-lock, said means being operativcly connected with said latch-holt when the dead-lock is oil, and additional and independent means externally of the door for retracting the latch, including kcy-contralled mechanism discore nected from the latch when the dead-lock is HENRY (i.
