LOCK.
SPECIFICATION forming part of Letters IPatent No. 291,645, dated January 8, 1884.
Application filed July 16, 1883.
To all whom. it may concern:
Be it known that I, ANDREW B. TODD, a citizen of the United States, residing at Cheshire, (P. 0. address, South Meriden,) in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Locks, of which the following is a specification.
My. invention relates to an improvement in flat-keyed locks; and the objects of my inven tion are to simplify the construction of the locks and to render the same more difficult to pick, and also to so arrange the lock that the bolt is thrown by a lateral movement of the flat key. I attain these objects by the simple mechanism illustrated in the accompanying drawings, in whichi Figure 1 is a side elevation of one form of my improved lock. Fig. 2 is a side elevation of the reverse side of the same. Fig. 3 is a plan view of saidlock with one-half of its case removed. Fig. 4 is a transverse section thereof, the plane of section being indicated by the line a: w of Fig. 3. Fig. 4; is a side elevation of the inner end of the bolt. Fig. 5 is a side view ofmy key. Fig. 6 is a sideelevation of a lock, showing my improvement as adapted for use upon a trunk or chest; and Fig. 7 is a side elevation, with one side removed, of a pad ock containing a part of my improvements.
.L'ut: lock represented in Figs. 1 to 4, inclusive, is of that class which is a door-bolt upon one side, and a look upon the opposite side. If desired, instead of the bolt proper, thisimprovement may be applied to alatch for a bolt having a beveled end, and it could also be applied so as to operate a bolt by the key from either side of the door.
A designatesythe bolt, which is provided with an operating-handle, B, the shank of which works in a longitudinal slot having a notch, a, at its outer end, into which the shank of the handle is depressed by means of the spring b, Fig. 4, whenthe bolt is thrown within the keeper or projected from the lock-ease. This causes the bolt at its inner end to have a swinging movement in addition to its longitndinal movement, thebolt being fitted within the plate at the outer end of the case with Sufficient looseness to permit said movement.
iModel.)
As shown in the drawings, this case is adapted to be let into a mortise made in one side of the door, while the key-hub C will be let through a hole bored in the door to receive it, 5 5 and its end may be covered by the plate or escutcheon D. The hub C is provided with two keyways, which come together in the form of a V, as shown most clearly in Fig. 3, and so as to form a single keyway at the outer end of 6O the hub. One of these keyways is for the insertion and removal of the key while the bolt is within the casing or in its unlocked position, and the other is for a like movement of the key when the bolt is thrown outward or 65 into its locked position. Within these two keyways, which diverge from the singlekey way at the opening, I arrange series of wards, c, which in side view conform to the hitting, or notches in the edges of the key, as most 0 clearly shown in Figs. 4 and 5. This permits the properly-formed key, after being inserted in one of the keyways and carried inward to a proper position, to be moved sidewise or laterally over these wards into the opposite key- 7 5 way.
The inner end of the bolt B is recessed, as shown in Figs. 4 and 4, so as to receive the end of the key, Fig. 5, said recess being pro vided with a shoulder, h, to act as a stop for so the point or corner f on the key and limit the endwise movement of the key. The opposite corner of the key is beveled, as clearly showninFig. 5. henthelock-boltisthrown outward, the shank of its knob 13 falls into 8 5 the notch a of the case, and prevents the bolt from being moved forward until said shank is raised out of this notch. For unlocking the bolt, the key is inserted through the righthand keyway, Fig. 3, when its upper beveled o corner will enter the recess in the bolt, and, acting upon the upper wall thereof, will lift the inner end of the bolt sufficiently to withdraw the shank of the knob B out of the notch a The key will then be limited in its end 5 wise movement by the corner f striking the shoulder h, after which it may be moved sidewise like a lever, carrying the bolt inward into the position shown in Fig. 3, and leaving the key in the keyway through which the line 100 :0 :1; passes. The key may then be removed, if desired. The wards between these two keyto the key as those shown in Fig. 4-.
ways may be made of any desired shape, and they may be readily so formed that the lock cannot be picked by a wire run into either of the keyways, as the same could not be moved laterally by the wards.
In Fig. 7 I have shown the same general plan of a look, so far as the sidewise movement of the key and the wards are concerned, as applied to a padlock. Instead of a longitudinally-moving bolt, I have herein provided a swinging bolt or dog, E, and I have shown only a single keyway, Zr. Upon one side of this keyway I form a series of outwardly-projecting pins or wards, c, which pins or wards will sustain the same relation To unlock this lock,the key is inserted through the keyway it until its point rests upon the shoulder a of the dog E. The key-handle is then lifted, so as to move its inner end downward sidewise, and thereby throw the dog E far enough back to disengage it from the shackle. The wards c prevent the key from being thus moved sidewise until the key is in proper position over the wards. In order to withdraw the key,it is necessary to move it laterally into the same position in which it was inserted. A suitable spring may be employed to hold the dog E into engagement with the shackle, in which case the lock will be self-acting upon closing the shackle.
In Fig. 6 I have shown the exterior of a lock adapted for a chest or trunk, the interior some;
of which is the same as that shown in Fig. 7..
These different illustrations are believed to 3 5 be sufficient to show the general plan of making locks of different classes,which are adapted to be operated by the lateral lever action of a flat key.
I claim as my invention 1. A look provided with a keyway for the insertion of a flat key, by the side of which keyway is a series of wards, in combination with a flat key notched at its edges, and adapted to throw the bolt or dog by asidewise lever action, substantially as described, and for the purpose specified.
2. The combination ofalongitudlnally-moving bolt, the lock-case provided with a double keyway in V form, meeting each other at or near the outside, and the series of wards between said two keyways, substantially as described, and for the purpose specified.
3. The combination ofalongitudinally-moving lock-bolt having a drop motion for looking it in its projected position, the double keyway having a single opening at theouter end, and the key having the beveled corner for raising the bolt preparatory to throwing it, substantially as described, and for the pur 60 pose specified.
