LOCK.
SPECIFICATION forming part of Letters Patent No. 664,422, dated December25, 1900.
Application filed November 15, 1899. Serial No. 737,141. (No model.)
1'0 ctZZ whom it may concern:
Be it known that 1, WILLIAM B. MOORE, a citizen of the United States, residing at Ohicago, Illinois, have invented Improvements in Mortise-Locks, of which the following is a specification.
My invention relates generally to improvements in mortise door-locks; and the primary objects of my improvements are to provide a lock of this character which may be readily converted from a right-hand to a left-hand lock, thus avoiding the necessity of making one pattern for right-hand doors and an another pattern for left-hand doors; to provide an invertible as well as a reversible lock in the same pattern; to provide a lock which may be changed from a cylinder-lock to a key or tumbler lock; to provide a lock which when used as a cylinder-lock the cylinder will be above the door-knob and when used as a keylock the keyhole will be below the knob; to pro vide a lock in which the latch or bolt locking parts operate by gravity; to provide a lock in which the latch'or bolt locking parts operate by gravity equally as well when the lock is inverted as when in its normal position; to provide a look in which the latch or bolt will be locked automatically by the closing of the door, and to provide a lockin which the latch also performs the function of a bolt.
In carrying out the foregoing objects and others of economy of construction and simplicity of operation I provide a reversible front or face plate in order that my lock may be used on doors having beveled edges and reversible operative parts of novel construction and arrangement, as will be described hereinafter and as illustrated in the accompanying drawings, which form a part of this application for patent, and in which- Figurel is a side elevation of my improved lock in the cylinder-lock form, the cap-plate being removed to show the operative parts,
which are in their normal position taken tion of the reverse side of the parts shown in Fig. 3. Fig. 5 is a cross-section of the front vcylinder-lock form.
or face plate and the adj usting-plate applied thereto. Fig. 6 is an elevation of the look when used as a key-lock, the method of applying the keyhole-plate being shown. Fig. 7 is an elevation of the look when used in the Fig. 8 is a rear elevation of a sliding bar for releasing the lockingplate; Fig. 9, a detail of the key-plate; Fig. 10, a detail of the cylinder.
Referring to the drawings, 1 represents a lock-case, to which are secured a cap-plate l and a face-plate or front 2. In order to apply my reversible lock to a beveled-edge door, it is necessary to provide a reversible front, and this I accomplish by interposing between the front and the edge of the case a beveled plate 3, such plate being removably attached, so that it may be discarded if the lock is applied to a door having a straight edge instead of a beveled edge. The inner side of the front has formed thereon studs 2 the ends of which are threaded to receive suitable nuts, and these studs pass through elongated slots 3 in the plate 3 and also through suitable holes formed in the lugs 7 upon the lock-case, s01 that by screwing up the nut-s the front bev-j eled plate and case are secured together. In
order to change the angle of the front, it is only necessary to unscrew the nuts, remove the front, turn over the plate 3, and then restore the parts to their former position.
When used in the cylinder form, I mount on the square shank or spindlef of the cylinder F a disk or hub A, in which a square opening a is formed for the spindle f, thus effecting the rotation of the hub with the cylinder. Extending from the periphery of the hub A is an arm a, which is so positioned that upon the forward rotation of the hub the said arm will strike against and push rearwardly the end (1 of the lever D, the lower portion of which is pivoted on a stud 5 upon the case and is provided with an angular extension (1. The same movement of the lever D is also obtained through themedium of the hubs H H, which are mounted through their central perforations h on the square shank of the doorknob K, which is of the usual form. The hubs have shoulders 71 formed thereon,which abut against shoulders (Z on the lever D, thus operating the lever when the hubs (or either of them) are rotated forwardly upon their axis.
The hub -H has a notch h in its periphery at a point directly opposite the inner end i of the hub-locking bolt 1. This bolt 1, together with its companion bolt 1, is pivoted to a lever J, mounted on a stud 6 upon the case, extends through the plate 3 and the front, and by being pushed backward or forward serves to lock or release the hub H, constituting the well-known method of preventing the unlatching of the door by turning the outsideknob. As this feature of my lock is of the usual construction and operation, it need not be described in detail in this connection, it forming no part of the invention.
A spring 12,having one end secured against the lug 7 and bent over the pin 6, has its other end bearing against the end d of the lever D, so that the normal tension of thespring is to throw the opposite end of the lever forwardly. A spring 13, secured to the lugs 8 and bent to form a bowed portion near its center, bears against the lower end of the lever J and retains it in its adjusted positions in a well-known manner.
To the under side of the lever D, near its end (1, is fixed a pin cl in position to engage the slot 19 in the latch-bolt B and the slot 0 in the lockingplate C, said pin normally pressing against the forward side of said slots, and thus forcing the latch-bolt B forwardly. The latch-bolt B has the usual beveled end b extending through suitable openings inthe plate 3 and the front and is adapted to engage the socket in the strike when the door is closed. The latch-bolt is made reversibleand is formed with a square slot 12 near its rear end and an oval slot 1) just forward of the center. A pinb extends through the latchb'olt at a point just back of the shoulder 11* formed by the end I), which is thicker than the body of the latch-bolt, said pin project- 'ing equally on each side of the latter. Pivotally mounted on the lower end of the pin b is a gravity locking-plate O, whichin the form "shown serves also as a tumbler and fits snugly to the under sidebf the latch-bolt. In the upper side of the locking-plate C a pin 0 is fixed in position to fit loosely in the oval slot b in the latch-bolt; and near the rear end of said plate is formed a triangular slot 0 which when the locking-plate and-the latch-bolt are in position cornes directly under-the square slot 1) in the latter and surrounds the pin d i'n'the lever D; At right angles with the body of the -locking-plate an extension 0 is formed, in the'rear side of which is a notch c, and in the lower rear corner a lu'g or shoulder c is formed with a slanting edge toward the'front of the case, said lug serving as a stop for the key when one is used.
Secured to the inner side of the case at 'pointsjust above and below the upperand lower edges of the latch-bolt B are elongated lugs 4, which serve as guides for the said latch-bolt when. it is pushed inwardly and as stops for the locking-plate when it falls belo-w't'he plane of either of said lugs.
When the pin 0 is directly in the center of the oval slot b it, the pin b, and the pin 01 will be in the same line, and the latch-bolt and the locking-plate will move in the same horizontal plane and are normally held in this position by the bar E. The latter forms a part of what I term a locking latch-bar. It has a beveled front end 6, which projects through suitable openings in the plate 3 and the front 2 and is formed with steps or shoulders e on the upper and lower sides, on one of which the lower edge of the latch-boltrests and is thereby supported in its slidingmovement.
At each end of the bar E is a notch e 6 the former embracing the post 10 of the case and the latter partially surrounding the pin 0 of the plate 0. A portion of the bar is cut away, leaving a shoulder E, against which bears one end of a'spring 6 which is wound about a post 10 and has its opposite end bearing against the bottom of the case, thus causing the normal tension of said spring to bear against said shoulder and shoot the bar eoutwardly, which position will be maintainedso long as the door is opened. In this position the bar E by its forward pressure upon the pin 0 and by the sides of its notch e will furnish a support for the locking-plate and maintain it in its horizontal position. When the bar E is retracted by the pushing inwardly of its forward end 'e, the notch e leaves the pin 0 thus releasing the locking-plate, so that it will fall'by gravity thedistance permitted by the pin d and when it has so fallen the notch 0 will be below the "lower lug 4 and the rear end of the locking-plate will strike against said lug when an attempt is made to retract the latch-bolt, thus effectively locking the latter until the latch-bolt is raised to its for- 'mer and normal position. This return of the locking-plate to its horizontal position in line with the latch-bolt may be accomplished in two different ways. If a key be used, the locking-plate may be raised until its notch c registers with the lug 4, and the same result would be accomplished if several plates were used, each having a suitable notch to receive the lug 4. The plate will also be raised by turning the lever D-backwardly, thus'causing the 'pin d to bear against the upper sloping edge of the slot 0' in said plate and continuing the movement until the notch c registers with the adjacent h1g4 and the pin strikes against the rear wall of the slot 19 and thus retracts the latch-bolt B. When the door is opened, the latch-bolt will be shot forward by the actionof the spring'12 on the lever D and also by the action of the spring 6 on the bar E, which will also be shot forward, the notch e returning to its'norinalposition about the pin 0 When the door is closed against the strike S, the latch-bolt end b will enter the socket provided therefor; but as no opening will be provided for the'end e of the bar Ethe latter will be pushed inwardly, aud'when in "such retracted position the operation above described will take place.
If it should be desired to operate the look by means of a key in place of a cylinder, I remove the cylinder and the hub A and apply the key-plate K, ways being provided therefor in the back and cap of the case. Said plate may be held in position on the case by being sprung into the ways or by a screw is passing through a suitable opening in the bottom of the plate and into a threaded opening in the bottom of the case. By inserting a suitable key and turning it until it strikes against the lower edge of the plate 0 the latter will be raised until the notch c registers with the log at, and by continuing the movement of the key it will impinge on the shoulder 0 and thus retract the plate and with it the latch-bolt B, thus unlocking the door, which has been automatically locked by the closing thereof, as heretofore described.
Should it be desired to use the lock in the cylinder-lock form,the key-plate K is removed, and the cylinder, with the hub A mounted on its spindle f, is inserted in the case, the arm Ct being in position opposite the end d of the lever D, so that upon the rotation of the cylinder the lever D will be operated in the same manner as by the hub H, which has been described. The casing of the cylinder, which is of the usual form, will be fitted to the opening f in the cap-plate.
I am aware that reversible and gravity locks are common; but it will be noted that my improved look, while possessing the gravity features, is invertible as well as reversible, thus providing that when used as a key-lock the keyhole be below the door-knob, and when used as a cylinder-lock the cylinder containing the keyhole be above the door-knob in the usual manner. I am aware that reversible latches are common; but it should be observed that my reversible latch performs the function of the usual bolt employed in most locks in addition to the latch. I am aware also that locking-plates have been used which work by gravity, but the same have been pivoted to the lock-case,while in my lock the said plate is pivoted to the latch-bolt. Attention is invited to the peculiar construction of the hub A, in that both sides are alike, thus permitting the application of the cylinder from either side of the lock.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. In a l0ck,a sliding latch-bolt and invertible means for locking same in its projected position in connection with stops secured to the lock-case, said means being pivotally secured to said latch-bolt and operating by gravity to lock the latch-bolt in said position.
