20 Claims.

being movable independently of the outside handle so that the outside handle may remain-locked and yet not interfere with the operation of the inside handle.

It is a feature of my invention that the outside handle is adapted for swift assembly and disassembly relatively to the door on which it is carried. A further feature of my invention resides in the mounting of the handle and its operating means as a simple and single unit on a door lock whereby to eliminate the need for the usual mounting of a series of individual parts.

Thus, through the use of my invention itis possible for the manufacturer of an airplane to apply his locking mechanism to the door in an exceedingly simple and efiective manner and without the necessity of mounting on the door a series of small parts individually applied to the door.

I have thus described generally the more important features of my invention in order that the relation of my invention to the prior art may be better understood. Those skilled'in the art will readily appreciate from the detailed description that follows, that the basic concept of my invention may be utilized with mechanical means difierent from those that i shall herein describe, and that my invention should not be limited to the structures set forth in this application.

Referring now to the drawings,

Fig. 1 is a view of a portion of a door taken from the outside thereof showing the locking handle of my invention applied to the door, and illustrating the locking means that are applied on the inside of the door and are actuated by the locking handle.

Fig. 2 is a section taken along lines 2-2 of Fig. 1.

Fig. 3 is a section taken along lines 3-3 of Fig. 2.

atively to the plate III are designated by reference numerals I l and Ila. Secured to the surface plate III of the door is what may be termed anescutcheon or mounting member for the outside handle. This escutcheonor mounting member is designated by reference numeral I2 and is formed with a grooved horizontally extending portion l3, and a, relatively large end bearing portion II. A continuous flange I 5 of the es- Fig.4 is a section taken along lines 4-4 of Fig. 2.

Referring now more particularly to the drawings, the surface of the door to which my lock is shown applied is in the form of a steel plate des ignated in Fig. 2 by reference numeral to. Inside mounting plates for supporting the lock relcutcheon or mounting member I2 is secured against the outside surface of the door surface plate Ill, and a series of holding screws I8 carried by the plates H and Ila are driven into threaded bores lGa of the'mounting member I2, so that the escutcheon or mounting member I2 is thus readily secured. to the door, all as will be apparent.

At the end of the horizontally extending portion I3 01 the mounting member l2 there is mounted a locking key plug ll adapted for rotation relatively to the mounting member upon the proper positioning of the series of usual key set tumblers l8. The key plug l I is equipped with a pin l9 that is adapted in the standard manner known in the art to retract and project a sliding'lo'cking bolt 20. It is the function of the locking bolt 20 when in its dotted line position, to enter a notch 2| in a handle 22 so as to lock the handle 22 in its full line position of Fig. 2. When the bolt 20 is moved into its full line position the handle 22 is of course released and may move to its dash and dotted line position of Fig. 2, all as will be made more apparent hereinafter.

Carried on the mounting plate ll of the door are devices adapted for operation to project and retract the five bolts 25, best illustrated in Fig. 1.

Each of these bolts, as best illustrated in Fig. 2, is pivoted through a pin 26 to a plate-like device 21 that I term a crank for convenience in describing the apparatus, it being obvious that many types of bolt operating devices may be used as equivalents thereof. This crank 21. ha a square opening 28 whereby it may fltpn a square spindle 29. The spindle 29 is made integrally with a thimble 30 that is mounted at 3| for gotation on the mounting plate I l A square opening 32 is formed in the thimble 30 for a purpose to be presently indicated. Secured for rotation with the thimble 30 on the spindle 29 is a control and limiting plate 33 which through its shoulders 34 limits the rotation of the spindle 29. A spring 35 cooperates with dwells 36 on the-control and limiting plate 33 for yieldingly maintaining the said plate 33 and the spindle 29 in either one of 2 two positions corresponding to the dwells 26 and determined by shoulders 24. Y

A retaining member 31 that is best shown. in Figs. 3 and 4 is adapted to hold the control and limiting plate 33 and the several parts described, in their operating position. For the particular purpose the retaining member 21 is formed with tabs 38 that enter openings in the bearing plate ll so that it may be secured to the plate ll,- all as is quite apparent from the drawings. Spacers and washers such as those shown in the drawings may be used to hold the several parts in their relative positions. It may be well to indicate that the assembly of the part used to rotate the crank plate 21 is merely illustrative of a particular group of parts preferably utilized b me.

An inside handle 39 is secured as through a screw 39a for rotation with the spindle 26. A further screw 40 that is in threaded engagement with a threaded bore 4| of the spindle 29 serves to hold the handle "against endwise removal from the spindle. It is obvious of course that rotation of the handle 85 will rotate the spindle 26 to project or retract the several bolts 25 through crank plate 21 and that this will lock the door or release the door for opening.

I shall now describe the manner in which the outside handle 22 retracts and projects the several bolts 25, it being now clear that the inside handle operates independently of the outside handle when moving the bolts 25. v

The bearing portion l4 of the handle mounting member I2 is formed preferably with a circular opening 45. A handle bearing member that I prefer shall take the form of a cylinder 46, is

adapted for insertion into the opening 45 and with its end surface 41 preferably against the mounting plate Ii. Once the cylinder 46, which functionally is really a bearing for the rotation of the'handle 22, is inserted in the opening 45. a retaining screw 46 is threaded into the mounting member 46 through a slot 49 of the bearing portion l4 of the handle mounting member l2. 'It is obvious of course that the screw 46 will thereafter hold the cylinder 46 against movement outwardly of the opening 45, and that the said screw 46 may also limit the rotation of the cylinder 46 and the handle 22 mounted thereon.

The handle 22'is mounted on a pivot shaft 50 relatively to the cylinder bearing 46 as is probably best illustrated in Figs. 2 and 4. The ends of the pivot shaft 50 are of course maintained covered when the cylinder 46 is within the bearing opening 45 of the handle mounting member l2 as best seen from Fig. 4. The handle 22 is thus adapted for pivotal movement from its full line position of Fig. 2 to its dash and dotted line position of Fig. 2 whenever it is released by the bolt 20.

The cylinder 46 is preferably formed with an opening within which is adapted to slide a square spindle 52. This square spindle 52 is guided at its upper end relatively to the opening 5| by a plate 52, and is guided at its lower end by an opening 54 in the bottom of the cylinder 46. A spring 55 maintains the plate 52 in the extreme upper position illustrated in Figs. 2 and 4, in which position it bears against the surface 56 of the handle 22. Because of this relationship of the parts the spring 55 not only serves to maintain the square spindle 52 in its upper full line position of Fig. 2 and preferably entirely within the cylinder 46, but also yieldingly maintains the handle 22 entirely within the groove 22a of the handle mounting member l2. In this position of the parts the handle 22 is of course substantially flush with the surface of plate ll of the door and the flange II of the escutcheon or handle mounting member I2. In an assembly of this type it is desirable that the handle 22 lie in the groove 2211 so that no tool may be inserted to pry the handle out of the groove 22a.

When the handle 22 is moved to its dash and dotted line position of Fig. 2. the square spindle 52 will move downwardly from its full line position to bring'the square spindle 52 into the square opening 82 in the thimble I5. Thereafter, rotary movement of the handle 22 will effect the rotation of the cylinder 46 in the bearing opening to rotate the square spindle 52, the thimble 36, and the spindle 25. This rotation of the parts will of course rotate the crank plate 21 to retract or proiect the several bolts 25. Shoulders 34 of the limiting and control plate 25 will of course limit the rotation of the handle 22, and the spring 25 will yieldingly maintain the handle and the several parts in one of two positions-corresponding to the dwells 25.

It will now be apparent that anyone on the inside of the door may retract or project the bolts independently oi the condition of the outside handle. It will also be apparent that the outside handle 22 may be used to project or retract the bolts 25 when it is desired. it will also be obvious that the assembly of my locking mechanism is extremely simple, since once the escutcheon or handle mounting member I2 is applied to the door, the mere insertion of the cylinder bearing 46 of the handle 22 into the opening 45 will immediately effect an operating assembly of the parts of my invention.
