UNITED STATES t PATENT OFFICE 2,201,963 Y noon HANDLE ASSEMBLY Avagm Wartian, Detroit, Mich., assignor to The Yale & Towne Manufacturing Company, Stamford, Conn., a corporation of Connecticut Application February 2s, 1937, serial No. 127,945

24 Claims.

.two modications of my invention, one modification being' divided out of my application for patent, Serial No. 90,125, led July, 1l, 1936.

Each modication may be used in handle Vassemblies in which the handlelies in Various liush or semi-flush positions relatively to the door on which the .assembly is mounted.

One form of my handle assembly comprises in general, a recess outlining member which is so mounted in the recess of a door as to outline that recess and form a decorative and protective support for a pivoting handle. The handle moves on its pivot out of lthe recess when operated to retract a latch bolt maintaining the recessed door locked. Means are provided for locking the handle within the recess outlining member against unauthorized operation, and it is iin-V possible to remove the handle from the recess outlining member until the said handle locking means have been released. Similarly, it is impossible to remove the recess outlining member from the door recess until the handle locking means are operated. vIn this way, unauthorized removal of the handle assembly will, of course, be prevented.

More particularly, the form of my invention which utilizes a recess outlining member utilizes also an escutcheon member to which my handle is pivoted. This escutcheon may or may not be integral with the recess outlining member. A single means is provided for securing the recess outlining member and the escutcheon to the door, the said means being accessible only after the door is opened through authorized operation of the handle.

As a. further important feature of this modi-V fication of my invention, the recess outlining` member has a cut-away portion with which cooperates a latch bolt carried by the handle. This latch bolt locks the handle to the recess outlining member and against pivoting movement on the escutcheon, the latch being operable to release the handle by a push button or push cylinder carried by the handle. It is desirable to use a latch bolt for locking the handle within its recess so that the handle may be easily Dressed (ctn-s) into its recess and automatically locked therein. Since usual forms of latch bolts do not have the security. I require I have arranged a novel way of mounting my latch bolt so that when it latches the handle within the recess, it is placed in a dead center position so that it really functions quite effectively to maintain the handle within the recess thereafter.

lAs a further feature of this modification of my invention, I so design my handle that that 10 portion extending laterally from the latch carrying portion for hand operation is relatively thin, so that if force is exerted thereon in an attempt to break the latch bolt, it is the handle` which will be broken rst. This, of course, prevents a forcing of the door lock, as will be a preciated by those skilled in the art.

In the` modicatign of my invention, divided out of my application supra, I do not show a recess." outlining member, although one could zo readily be used, should I so desire. In this modiflcation of my invention, the latch bolt locking the handle within the recess so cooperates with means for securing the escutcheon on whichthe handle is pivoted, that the handle cannot be removed :from its recess, nor can the escutcheon be released from its recess and theentire assembly be removed until an authorized person operates the cylinder lock or other means to release the handle from the recess. It is only thereafter that the assembly maybe removed.

For a description of my invention, I shall refer to the drawings, wherein Fig. 1 is a view of my handle applied to a door, certainj parts on the inside of the door constituting a part of the lock being shown in phantom dotted lines. Fig. 2 is apartial section `along lines 2-2 of Fig. 1. Fig. 3 is a partial view of part of Fig. 2 along the lines 3-3 of Fig. 2. Fig. 4 is a section along lines along lines 5 5 and 6 6 of Fig. 1, showing the handle in two of its positions relatively to the escutcheon and the recess outlining member.

Fig. V' is an exploded view in perspective of the '4 4 of Fig. 2. Figs. 5 and 6 are partial sections 40 handle assembly utilizing the recess outlining member. Fig. 8 is a perspective view of the bolt retracting cam of my invention. Fig. 9 is a front view of a Vliiodilication of my invention forming a division of my application supra. Fig. 10 is a section along lines Ill-I0 of Fig. 9. Figs. 11 and 12 are views illustrating the cam action of the sliding cylinder utilized in the handle of my invention.

Referring now more particularly to the drawings, and especially to Fig. 7, one form of my u handle assembly comprises a recess outlining member I0 having an extended portion II adapted to fit under the end surface I2 defining a door recess I3, as is probably best shown in Fig. 2 A bead I4 formed on the recess outlining member I0 is adapted to overlie the face of the recess I3, as is best illustrated in Fig. 1. A handle I5 having a long thin hand grasp I6 and a main body portion I1, is pivoted at I8 to an escutcheon member I9. Ears 20 on the escutcheon member I9 fit behind shoulders 2I of the recess outlining member I0, while end surface 22 of the escutcheon I9 fits against the flat surface 23 at the end of a cut out portion 24 of the recess outlining member I. The remainder of the escutcheon overlies the recess outlining member and secures it in position.

Surface 22 of the escutcheon member I9 lies against a plate 25 forming the outer edge of the door on which the assembly is mounted. A screw 26 traverses the edge plate 25 of the door and enters a screw threaded bore leading into the escutcheon I9 from its surface 22, thus securing the escutcheon to the edge of the door. It will be appreciated that because of the relation of the escutcheon to the recess outlining member as previously indicated, the end of the recess outlining member adjacent the edge of the door will beheld securely in the recess of the door. At the lsame time, the portion II of the recess outlining member will hold the other end of said member within the recess I3. In eiect, what I have is an interlocking overlapping connection II, I2 which has somewhat the character of a bayonet joint. This connection. is held against release by the screw 26, which is accessible only when the door is opened. Since the door may not be opened except by an authorized person, as will be indicated later, I obtain a very effective locking of my assembly relatively to the recessed door, as will be readily appreciated.

For convenience in manufacturing, which, incidentally, I consider a forward step in the art, I form the recess outlining member I0 of sheet metal while escutcheon I9 is made a separate die casting. I can readily, as a step backward, form the recess outlining-member and the escutcheon of one piece.

I shall now refer to Figs. 5 and 6 for a descripl tion of the operation of my handle. There it Will be seen that the handle I5 has a portion 21 extending beyond pivot I8 on which the handle is mounted relatively to the escutcheon I9. Portion 21 of the handle is adapted to operate a bolt retracting cam 29 when the handle is swung from its position of Fig. 5 to its position of Fig. 6. The handle I5 has mounted on a pivot pin 30 thereof, a latch bolt 3l which cooperates ywith the surface 32 of the opening 24 of the recess outlining member I0 for securely locking the handle against movement outwardly from the recess outlining member. Furthermore, the pivot 30 is so arranged relatively to the latching surface of latch 3l that the said latch will be maintained in an effective dead center relation to resist the release of the handle from the recess outlining member I0, as will be readily understood by those skilled in the art.

A spring 33 carried by the main body I1 of the handle tends-to maintain the latch 3| in its dead center locking position, while also forcing the arm 3Ia of the latch 3l against the end of a cylinder lock 34. This cylinder lock 34 is adapted for sliding movement relatively to the main handle body I1, -this movement being controlled by a pin 35. A cam 36 carried on the end of the cylinder 34 -and rotatable under the control of a key in a manner well understood by those skilled in the art, cooperatesryth a slot 31 in the handle body I1 in one position thereof for maintaining the cylinder against sliding movement. This is probably best illustrated with reference to Fig. 12. In three handles of an automobile a simple push button will be used, but on the fourth handle a key operated cylinder is used, as is usual in this art.

When a key is inserted in cylinder 34 and the cam 36 rotated from the position of Fig. 1l to the position shown in Fig. 12, the cylinder 34 will be freely slidable so that it may act on the arm 3Ia of latch' 3l, to rotate the latch into release position against the force of spring 33. Immediately upon the release of the latch 3| from the recess outlining member, a spring 38 acts on the said handle to eject it from its recess, the degree of movement imparted being substantially that shown in dotted lines in Fig. 2. Thereafter, the handle may be grasped and a full rotationimparted thereto so that the bolt retracting cam 29 may function to retract the lock bolt, as will be indicated presently.

It will be readily appreciated that a simple push of the handle from the dotted line position of Fig. 2 or the position of Fig. 6 back into the recess outlining member I0 will automatically cause a relatching of the latch 3I for locking the handle within the recess. It should also be indicated at this time that the hand grasp I6 of the handle I5 is made of such strength that should anyone attempt to jimmy the handle. out of the recess, the said hand grasp I6 will break before the latch bolt 3I will give way.

In Figs. 9 and l0, I show a modification of my invention in which no recess outlining member I0 is utilized. There, a handle 40 is pivotally secured at 4I to an escutcheon plate 42. The handle has a relatively long hand grasp which is drilled out as at 43 for housing a latch bolt 44, which is spring pressed outwardly by a spring 45 and locks under the surface 49 of one end of the recess. The latch bolt 44 is retracted somewhat in the same manner as latch bolt 3| in my first modification, there being a latch retracting bell crank lever 46 pivoted at 41 to the handle and operated by the pushing in of a cylinder 34, which is the same cylinder as used in the previous modification, and being locked to the handle by a locking cam 36 in the same way as in the first modification.

The escutcheon 42, instead of being secured.

through an end surface to the edge of the door as in Figs. 2 and 5, is secured by a pair of screws at the front of the door, the screws cooperating with holes 48 in the said escutcheon. In addition, it has an ear 50 tting under the surface 5I of the end of the recess opposite the end cooperable with the nose of the latch bolt 44. It is obvious that with the latch bolt 44 locked under the surface 49 at one end of the recess of the door, and with the ear 50 of the escutcheon under the surface 5I at the other end of the recess, endwise movement of the assembly as a whole relatively to its recess will be impossible.

Therefore, even though the screws fitted through the holes 48 be loosened and removed, it will be impossible to remove the assembly from the door. Only upon the authorized retraction of the latch bolt 44 by operation of the cylinder 34, will it be possible to release one end of the assembly from the end surface 49 of the recess.
