ATTORNEY Patented Sept. 17, 1929 UNITED STATES PATENT OFFICE SIDNEY COHEN, OF NEW YORK, N. Y., ASSIGNOR TO DEFENDER LOCK COMPANY, INC.,
013 NEW YORK, N. Y., A CORPORATION OF NEN' YORK COMBINATION DOORLOCK Application filed February 18, 1929. Serial No. 340,940.
This invention relates to locks intended more particularly for. application to the doors of buildings, cabinets and lockers, the invention having for an object the provi- 5 sion of a novel and improved combination lock which can be readily manipulated, and which when used on the door of a building, permits of opening the door from the inside without setting of the combination.
Another object of the invention is to provide an improved lock construction of the character described comprising few ,and simple parts which shall be readily assembled to form a strong, rugged, compact, yet neat 15 appearing structure, which shall be relatively inexpensive to manufacture. and practical and eflicient to a high degree in use.
For further comprehension of the invention, and of the objects and advantages there- 2 of, reference will be had to the following de-' scription and accompanying drawing, and to the appended claims in which the various novel features of the invention are more particularly set forth. 4
Other objects of the invention will in part be obvious .and .in part hereinafter pointed out. This invention is similar to that disclosed in the applicants abandoned application, Serial No. 4,650, filed Jan. 26, 1925, and allowed October 7, 1927.
Fig. 1 of the drawing is a fragmentary outside face view of a door having my improved lock applied thereto. 7 V 4 Fig. 2 is a longitudinal vertical sectional view, this view being taken centrally of the lock.
Fig. 3 is a horizontal-sectional View of the door with the lock in elevation.
Fig. 4 is a transverse sectional view taken on the line l l of Fig. 2.
Fig. 5 is a face view showing a modified form of lock.
Fig. 6 is a transverse sectional View taken on the line 6-6 of Fig. 5.
1 Fig. 7 is a top view of a modified form of bolt.
In the drawing the reference numeral 10 indicates a portion of a door, and 11 a portion of the stile of the door frame the latter having 5 an ordinary keeper member 12 sunk in a that bear on the inner ends of the leg of the mortice therein. formed with a suitable mortice 13 covered on the inside by a small shutter 10' hinged as at 13 to the door and normally locked by a bolt 13*. On the inner face of this shutter is mounted a casing 14 of elongated rectangular form. This casing is shown here as having one solid end and the other end in the form of a cap 14- having a stud 15 projecting longitudinally through the casing and screwed into the solid end of the latter. The bolt is in the form of a U-shaped member 16 having a double-beveled front end whose central transverse part 16 is adapted to take into the keeper 12. The legs of this bolt are formed with notches 17 in which are engaged the edges of a series of permutation rings 18 that surround the stud 15 and are located in a sutiable cylindrical chamber in the casing 14. These disks are formed with notches such as 19 that are adapted to be brought into registry with the legs of the bolt to free the latter, and with flattened surfaces such as 20 on opposite sides to permit of adjustment of the rings to release one leg of the bolt without interference with the other leg.
The bolt 16 is urged to locking position by means of the coiled expansion springs 22 bolt, the latter being here shown as formed with sockets to receive these springs, which are held against buckling by pins 23 projected from the casing 14:. To withdraw the bolt, when the combination is set to free the legs from the engagement of the rings '18, .a pair of studs 25 are fixed to the bolt legs and pass outward through suitable slots 26 and have a handle 27 fixed'to and connecting their outer ends. The rings'18 register with a slotted aperture 28 in the casing 14 and have extended finger pieces 29 whereby they may be manually rotated to proper position.
The complete casing 14 is pressed toward the door frame by the'spring 81 fixed to the end thereof and bearing on a plate 31, and is arranged for retraction in the mortice 13 when the bolt is to be released from the inside without setting the combination. and to The edge of the door is this end a pin 32 is fixed to the casing and projects inward to the inner face of the door through a slot 33 in the latter. This pin has slidable thereon a knob 34 formed with a finger 35 that fills the slot 33 to hold the casing against retraction, a spring 36 in the knob retaining the latter in locking position. The finger 35 is formed on its inner face with a projecting stud 35 that may be engaged in a socket 35 in the shutter 10 to hold the casing in position with the bolt retracted. When the bolt is to be retracted from the inside the knob 34 is first pulled to free the finger 35, fromthe slot 33, and then moved to retract the whole casing, and with it the bolt. If it is desired to have access to the lock to change the combination, the shutter 10 may be swung to move the lock out of the mortice in the door, a slotted aperture 39 being provided in the outer part of the door to accommodate the handle 27 during thi movement.
In the form of the invention shown in Figs. 5 and 6 of the drawing the bolt 40 is formed with a square shank that extends centrally through the casing 41 and is formed with notches 42 in its corners adapted to be brought into registry with like notches 43 in the permutation rings 44 by rotary movement of the latter. The bolt is normally pressed outward by an expansion spring 45 and is retracted, when the combination is set, by means of a stud 46 fixed thereto and projecting outward through a slot 47 in the casing.
The latter is formed with the slotted apertures 48 and the rings with setting fingers 49 projecting therefrom through this aperture.
In Fig. 7 of the drawing I have indicated a construction for the legs of the bolt in which each leg is provided with a bar 52 slidable transversely therein and pressed laterally inward by springs 53, this bar having ratchet teeth 54 that engage the permutation rings, permitting the bolt to be slid inward to locked position irrespective of the setting of the permutation rings.
It will thus be seen that there is provided devices in which the several objects of this invention are achieved and which are well adapted to meet the conditions of practical use.
As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiment above set forth, it is to be understood that all matters herein set forth or shown in the accompanying drawing are to be interpreted as illustrative and not in a limiting sense.
Having thus described my invention, what I claim as new and desire to protect by Letters Patent of the United States is as follows:

A lock comprising a movable casing, a bolt in said casing having notched side leg portions, permutation rings engaglng said notched side leg portions of the bolt to hold it advanced, and separate means adapted to be projected on opposite sides of a door to which the bolt is applied for moving the bolt gack in the casing and the casing back in the 2. In combination with a door, a casing set therein, a bolt carried by said casing having notched side leg portions, a series ofpermutation rings engaging sai'd'notched side leg portions of the bolt to hold it advanced, and a member attached to the bolt and projecting through the face of the door for retracting the bolt.
3. In combination with a door, a casing set therein, a bolt carried by said casing having notched side leg portions, a series of permutation rings engaging said notched side leg portions of the bolt to hold it advanced, and a member attached to the bolt and project ing through the face of the door for retracting the bolt, and resilient means urging the bolt forward.
4. In combination with a door and door frame, a casing set in the door frame, to be movable toward and away from the said frame, a spring urging the said casing toward the said frame, a bolt sli'dable in the said casing, permutation locking means for the said bolt, and manually operable devices connected respectively to the bolt and the casing for selectively retracting either the bolt or the casing, the device for retracting the casing normally holding the latter in advanced position, and consisting of a pin projecting from the casing through a slot in the door, and a knob slidable on the pin and having a finger adapted to-lie in and along the said slot to prevent movement of the pin along said slot.
5. A look comprising a casing, a notched bolt in said casing, permutation rings engaging said bolt to hold it advanced, and separate means adapted to be projected on opposite sides of a door to which the bolt is applied for moving the bolt back in the casing and v the casing back in the door, said bolt having a movable ratchet toothed bar engaged by said rings and permitting free inward movement of the bolt.
6. In combination with a door, a casing set therein, a bolt carried by said casing, a series of permutation rings engaging said bolt to hold it advanced, and a member attached to the bolt and projecting through the face of the door for retracting the bolt, and a shutter hinged to said door and having said casing mounted thereon.
