To all whom it may concern:
Be it known that I, SAMUEL Ci-rnis'roriinn SIGMAN, a citizen of the United filtates, residing at Gladwin, in the county of Gladwin and State of Michigan have invented new and usefulImprovements in Door-Locks, of which the following is a specification.
This invention has reference to improvements in door locks and resides in the con struction, combination and operative ar-l rangement of parts set forth in the following specification and falling within the scope of what is claimed.
The accompanying drawings illustrate a simple and satisfactory embodiment of the invention, and in the said drawings:
Figure 1 is a perspective view of a portion of a door having a lock thereon in accordance with this invention;
Fig. 2 is an inner face view of one of the escutcheon plates;

posite the keyhole opening 1'? is arranged a revoluble disk 18 having a single slot 19 of a length equaling that of the keyhole opening 17. It will be apparent that the slot 19 must be brought to aline with the longer slot in the keyhole opening 17 before the key can be inserted, and that the bit of the key contacts with the walls provided by the slot 19 in the disk, so that the turning of the key will also cause the disk to turn, and the key can not he accidentally re moved from the escutcheon plate. It is to be understood that the door 12 is provided with a suitable notch for the disk and for the bit of the key, the inner wall of the said notch terminating'a suitable distance from the side of the lOCk14, and by this arrangement the key may be at all times retained on the inner escutcheon plate 13, if desired.
The body of the lock 13 is of the usual construction, comprising a substantially rectangular flanged casing 20 having a removable side plate 21. The side plate, as well as the casing have alining keyhole openings, and these members, inward of the said openings are provided with revoluble disks 22 respectively, each of the said disks having a slot 23 designed to aline with the keyhole opening, and when the key is inserted through either of the openings the turning thereof will cause both of the disks to revolve or turn, thus closing the keyhole openings in the lock casing and plate'and preventing the accidental removal of the key from the lock, in addition to providing protecting means for the lock, to prevent the inner parts thereof belng surrept1tiously tampered wlth by skeleton keys or other instruments.
In the casing 20, adjacent the lower portion thereof is arranged an auxiliary locking bolt 2 1 disposed to slide between suitable ways and having its under face formed with spaced notches 25. To the lower flange of the casing is secured the ends ofa substantially V-shaped spring 26, and to the inner to turn the bolt in its looking or in its retracted position.
One of the disks 22in the casing 20 has arranged thereover a plate or enlargement 30, suitably notched to receive the upper portion of the disk, and extending laterally from this plate or enlargement is a plurality of pins 31 that are arranged in staggered relation. The inner pin, or the pin nearest the inner end of the casing serves as a pivot for a tumbler plate 32, the said plate being provided with elongated openings receiving the remaining pins 31, so that these pins serve as a guide for the tumbler and limit the swinging movement thereof in two directions. The tumbler, at its upper and inner corner is provided with an outturned lug 33.
Arranged upon the face of the tumbler, but out of contact with the lug 13, and supported upon the pins 31, is a plurality of ward plates 34. These plates 34 are interchangeable and are provided, upon their lower edges with arcuate notches 35, varying in width and depth. The ward plates preferably have one of their faces provided with depressions 36 surrounding the notches 35 therein. Any desired number of ward plates may be employed, and the same being interchangeable may receive the wards on the bits of different keys, only one key, of course, being employed to lock the look, but at the same time the arrangement provides what may be termed a combination so that another key having different sized wards may be employed.
By reference to the drawings it will be noted that the upper central pin 31 projects a suitable distance beyond the re m'aining pins, or in other words is longer than the remaining pins, and this pin contacts with the upper edge of the slidable locking bolt 37 The lower edge of the bolt rests on the upper way for the auxiliary locking bolt 24. The bolt, from the inner edge thereof and upon its outer face is provided with a depressed portion 38, and the said depressed portion is notched or cut away in any desired shape from the lower edge thereof, as indicated by the numeral 39. The notch or cut-away portion is designed to receive therein the first ward of the bit and the depressed portion permits of the turning of the key not provided with the proper wards being turned around the bolt without influencing the same, even should the key have 1ts remaining wards shaped to turn through the notched portions of the ward plates.
The locking bolt 37 has its upper edge provided with two spaced notches 40 and 41 respectively, the lug 33 of the tumbler plate being received in the notch40 when the bolt is in its retracted position and in notch 41 when the bolt is in its projected position.
It is, of course, to be understood that the key 75, in operating the locking bolt first contacts with the lower edge of the tumbler, to swing the said tumbler, upon its pivotal connection with one of the pins 31 upwardly of the casing, and thereafter will contact with the shoulder provided by the notched or cut-away portion 39 in the locking bolt to move the said bolt longitudinally of the casing. The notch in the lower edge of the tumbler is such that the key, when retracting the bolt will not engage with the edge thereof, but the notch 39 in the bolt is such that the key will engage therewith, and thus draw the bolt inwardly to bring the notch 40 in" a position to receive the lug 38 on the tumbler. The key sweep plainly illustrated in Fig. 4 of the drawings is indicated by the numeral 39.
The tumbler is influenced, in bolt engaging position through the medium of a two-arm spring 42, the said spring being centrally bent upon itself to provide a coil or eye 43 that is received on a stud 44 on the casing20, one arm of the said spring overlying the lug 33.
The latch bolt is indicated by the numeral 45 and has its shank provided with an opening therethrough, the end walls of which being beveled in opposite directions to the center thereof. The opening is indicated by the numeral 46 and is designed to receive therein the second arm of the spring 43, the said spring influencing the latching bolt to an outward or operative position. The shank of the latch bolt, upon the inner end thereof is formed with two spaced rearwardly extending curved arms 47 respectively, each of which having an elongated slot 48, and passing through these slots are pins 49 secured to disks 50 that are connected to a hub 51, the said hub being disposed between the arms 47 of the latch bolt. The hub and the disksare provided with alining squared'openings 52 which receive the squared spindle 15 for the knobs 16.
From the foregoing description, when taken in connection with the drawings, the
advantages of the construction and the operation. thereof will, it is thought, be apparent to those skilled in the art to which such inventions appertain, it being understood, however, that I am not to be restricted to the device as illustrated and described, but am entitled to all such modifications as fall within the scope of what is claimed.
Having thus described the invention, what is claimed as new is 1. In a door lock, slotted revoluble disks opposite the key openings therein, a plate in the casing having a notch receiving the disk, staggered pins projecting from said plate one of which being of a greater length than the others, a spring influenced turnbler pivotally arranged on one of the pins and limited in its movement by the remaining pins, notched guard plates interchangeably supported by the pins, a slidable bolt contacting with the longer pin and engaged by the tumbler, and a ledge in the casing providing a support for the lower edge of the bolt.
2. In a door lock, a spring influenced pivoted tumbler arranged over the key openings therein, a slidable locking bolt normally engaged by said tumbler, interchangeable notched ward plates between the tumbler and bolt, and said guard plates hav ing depressions surrounding the notches thereof.
