Application filed February 3, 1921.

To all whom it may concern.-

Be it known that 1, WILLIAM LEON, a citizen of the United States, residing at Niagara Falls, in the county of Niagara and State of New York, have invented certain new and useful Improvements in Keyless Locks, of which the following is a specification.

My invention relates to keyiess lock, and more particularly to locks for doors trunks, chests, etc.

One of the objects of my invention is to provide a lock which can be easily and conveniently manipulated without the use of a key and wherein provision is made for actuating the same from either side of a door.

Another object of my invention is the provision of a keyless lock of this type which embodies a principle permitting the use of permutation mechanism comprising a single series of tumblers or a plurality of series and in which provision is also made for readily changing the concerted order of the tumblers so that a diiferent adjustment or manipulation of one or more of the tumblers of the series, or each of the series will be required to operate the look.

A. further object of my invention is the provision of a simple, inexpensive and durable device of this kind which is selfcontained and readily insertable or removable from a door or other object and in which the principle involved can be readily embodied in various modifications.

With these and other objects inaview to appear hereinafter. the invention consists in the novel features of construction, and in the arrangement and combination of parts to be hereinafter described and more particularly pointed out in the subjoined claim.

In the drawings Fig. 1 is a perspective view of a portion of a door showing one form of my invention applied thereto.

2 is a vertical section through the door and co-operating door jamb showing my improved keyless lock in sectional elevation.

Fig, 3 is a detached perspective view of a portion of the lock plate and one of the slotted sleeves carried therel v forming part of a telescopic rod.

Reference being had to the drawings in detail, like numerals refer to like parts throughout the several figures. 7

The numeral .11 designates a door. 12 a door jamb having a bolt-receiving pocket 13 and a bolt or latch plate 141- secured thereto. said bolt or latch plate being provided with the usual opening which registers with the pocket 13 so as to allow the belt of the lock to pass through said opening and enter said pocket. The door is mortiscd from its edge, as at 15. and one or both sides thereof, as may be desired. it is provided with an opening or openings 1.6 formed through one or both side walls of the mortise 15.

"in the drawings 1 have shown a lock which can be manipulated from both sides of the door and consequently both side walls of the mortise are provided with the openings 16 but it will be apparent that in a lock adapted to be manipulated from one side of the door only, the opening 16 is formed in one side wall only of said mortise.

The lock comprises a lock plate 1 which is secured to the edge of the door in a manner to close the front end of the mortise 15, and this plate is provided with a bolt opening 18 and with two inwardlvprojecting sleevelike members 19 provided with transverse slots 20 along diametrically opposite lines, the slots being arranged in two longitudinal series with the slots of one series registering with those of the other.

21 designates a frame which s preferably L-shaped with one arm 22 thereof disposed horizontally and preferably in slidable contact with the upper wall of the mortise and horizontal section 2, the door ami) section similar to its other arm 23 disposed vertically. Said frame has a lock-bolt 24: secured thereto which extends outwardly therefrom and the outer end of which is guided for movement in the bolt opening l3 of the lock plate 17.

Detachably secured to the vertical arm of the said lock frame are two supporting spindles or rods 25, each of which is entered in one of the sleeve members 19, and each having a series of pins 26 extending therethrough and projecting therefrom at diametrically opposite points. The opposite ends of said pins extend through the slots 20 at opposite sides of the sleeves 19 and proj ect a distance outwardly beyond the surface of said sleeves. The supporting spindles or rods 25 are preferably reduced at their inner ends to provide a shoulder which bears against the vertical arm of the lock frame, the reduced portion thereof extending through said arm and having a retainer pin 27 passed therethrough so as to securely hold said spindle on said frame and prevent longitudinal movement thereof.

The lock plate 17 and vertical arm 23 of the frame 21 may, in a broad sense, be termed supporting elements or members since they support the sleeve-like members 19 and the supporting spindles or rods 25, and said sleeve-like members and supporting spindles or rods may be termed telescopic rods, since said spindles or rods are adapted to slide with said sleevelike members.

In the drawings I have shown four pairs of slots 20 in each sleeve-lik member 19, each pair being comprised of opposite registering slots, and four pins 26 in each supporting spindle or rod 25, but these may be diminished or increased in number, as may be desired.

Surrounding each sleeve-like or outer rod member 19 are four inner tumbler members 28, each of which is provided with a bor 29 of a size to permit free rotation of said outer rod member, each tumbler member being counterbored, as at 30, to form an annular pin-way or groove and from said in-way or groove a longitudinal groove 31 extends, which at times will receive the projecting ends of the pins 26, as will be hereinafter described. By counterboring the inner tumbler member, forwardly-itaei11g shoulders 32 are formed therein.

Each of the inner tumbler members is also provided with an external longitudinal projection or rig 33 serving as a key, and being preferably l-shaped. Surrounding each of the inner tumbler members 28 an outer tumbler member 34, which is provided with a circular series of internal longitudinal V- shaped notches 35 serving as key ways. On the outer periphery of said. outer tumbler member a circular series of letters, figures, or other characters 36 are formed, one letter or other character being provided for each in the outer tumbler member.

In the preferred form, the diameter of the outer tumbler is somewhat greater than the thickness of the door so that with the lock positioned centrally in the door, or more particularly, with the telescopic rods positioned centrally within the mortise ot the door, the outer tumbler members project beyond opposite faces of the door.

The openings 16 formed in the door are closed by plates 37, which may be fastened to the door in any suitable manner, preterably so that the outer plate can be removed only when or after removing the inner plate, as and in the manner commonly provided for in the better class of out-door locks of usual construction now commonly employed.

Each plate 37 has two slots 38 formed therein. through which the outer tumbler members 3i can be manipulated, each plate having indicating or guise marks 39 with which predetermined characters on the outer tumbler members are adapted to be alined so as to position the lock mechanism to permit opening or the door. The lock bolt 2% is provided with a longitudinal opening 40, one longitudinal wall of which is provided with a series of gear teeth ll. Passing through the door and the plates 37 and projecting outwardly a distance from both plates is an operating spindle d2 having knobs 43 secured to opposite ends. Ata point midlength, this spindle is provided peripherally with teeth 4.4K which are .in mesh with the gear teeth l1 in the slot 40 and by means of which the lock trame and the inner members o1"- the telescopic ends secured thereto can he moved outwardly and inwardly.

With the parts in the position shown in Fig. 2; the lock oolt 24-, projected outwardly through the opening 18 in the lock plate i7 and extends into the pocket lI-lin the door jamlnthe tumblers being posh tioned to prevent rot tion of the operating spindle 4-2. l l ith the tumblers so positioned, the inner members are moved iorwardly in the outer members ii) of the telescopic rods with the pins 26 of s; 'd inner members engaging the front ends of the slots 2(), said pins projecting into the annular grooves or key ways 30, as clearly shown in Fig. 6. With the projecting ends of each pin thus arranged the inner members of the telescopic rods are held against forward movement by the inner end of the tumbler memberdirectly in advance and against rearward movement by the shoulder of the inner tumbler member with which it dircetly coacts.

With the pins rojecting within the pin ways 30 of the several tumblers, said tumblers are free to be rotated, but before it is possible to withdraw the lock latch 2% from the pocket 13 in the door jamb, it will be necessary that the longitudinal grooves 31 in the inner tumbler members be brought into alinement with the projecting ends of the pins 26, and to accomplish this, the operator must know the exact character of each tumbler which must be brought into alinement with the indicating or guide marks 39 on the outer or inner plate 37. When the tumblers are rotated so that all longitudinal grooves 31 therein are alined with the pins 26, the knobs 43 are free to rotate, and upon rotating said knobs, the operating spindle 42 to which they are secured will cause the lock bolt to be moved inwardly, which bolt being secured to the frame 21 will cause the inner members of the telescopic rods to move inwardly and the pins to enter the longitudinal grooves '31 in the inner tumbler members, as clearly shown in Fig. 7. With the parts in the positions last described, rotation of the tumbl r members is prevented, and the door is free to be opened or closed.

It is, of course, to be understood that any suitable spring or other catch device may be used in connection with this improved loclr. either as a separate unit, or as a part of this locking mechanism. It is also apparent that this locking mechanism can be arranged so that the tumblers are accessible from one side of the door only, and that any catch device employed can be ogerated from both sides of the door, so that the door may be held closed, although not locked. More over, in the event of the tumblers being accessible from one side of the door only, a key lock may be employed at the other side of the door in addition to this improved lockingmechanism.

Vl henever it is desired to change the combination, it is simply necessary to remove one or more of the outer tumbler members and place the key of the co-acting inner tumbler it would be possible to manipulate the locking mechanism. Therefore, the combination of one series of tumblers could be changed and the combination of letters on the other series of tumblers left intact; or if desired, both series can be changed so that if a combecomes known to others, it will be found a simple matter to change the combination to any degree desired, even to include an entirely new set of letters or characters.

ln 10, 45 designates a trunkor chest having cover 16, the cover being mortised, as at 15 and having a frame 21 provided with a slide bolt 2% at the inner end of the frame. In this modification the lock plate 17 is provided with an inwardly extending arm l7 to which the outer member 19' of the telescopic rod is secured. To the frame, above the slide bolt 2%, the inner member 25 of said rod is secured, and surrounding said outer member are shown tumbler members 33 of the permutation mechanism. This mechanism, which includes outer and inner tumbler members and the outer and inner members 19 and 25, respectively, of the telescopic rod, is identical with the permutation mechanism illustrated in the preceding figures of the drawings.

The trunk or chest to is provided with a pocket 13, and closing said pocket is a latch plate 14: having one or more openings 48. The lock bolt 24: is provided at its lower edge with one or more hookshaped projections 49, which are adapted to pass through the openings 18 in the lock plate 17 and through the openin s 48 in the latch plate, which latter openings register with the openings 18 in said lock plate. When the frame 21 is moved to the right hand end of the mortise 15, as shown in Fig. 10, the tumblers and projecting ends of the pins of the permutation mechanism will be in positions corresponding to those shown in Fig. 6, so that the toothed portion of the spindle e1 cannot be rotated to actuate the slide bolt 24. It is, of course, to be understood that the tumblers will be accessible from the exterior of the cover in a manner similar to that shown in Fig. l, and that when manipulating the tumblers and the proper combination of characters thereon are brought into concert and in line with some indicating or guide marl; on the cover 46, the lock can be actuated, or in other words, moved toward the left, and when so moved the hook ends of the projections 49 can be withdrawn through the openings 48 in the latch plate. 14.

The sleeve-like outer member of each telescoping-rod may also be consider d as a housing for a portion of the inner member, or the supporting spindle or rod 25, as more specifically termed.

Having thus described my invention, what I claim is The combination with a door having a mortise therein, of a keyless lock entered in said mortise and comprising a lock plate closing the outer end of said mortise, a supporting member spaced from said lock plate, a telescopic rod connecting said supporting bination which is being used to open the door member with said lock plate and comprising an outer sleeve-like member having a plurality of longitudinally disposed slots therein and an inner member having pins projetcing therefrom and extending outwardly through said slots, a lock bolt on said supporting member guided in said lock plate and having a longitudinal slot therein provided with gear teeth in one of its Walls, and

tumblers surrounding said sleeve-like outer 10 member, each tumbler havlng an mternal annular groove and a longitudinal groove opening into said annular groove, said pins projecting into said annular groove when said lock bolt is in looking position and into said longitudinal grooves when said look bolt is in unlocked" position, and a spindle provided oircumferentially with teeth meshing with the teeth in said slot.

In testimony whereof I affix my signature.

WILLIAM LEON.
