May 23, 1933. ROOT 1,910'Q'125 DOOR HANDLE Filed Jan. 2, 1932 INVENTOR wmwsss Ca lERoo ATTORNEY Patented May 23, 1933 UNITED STATES CARL H. ROOT, OF DETROIT, MICHIGAN noon manna Application filed January 2,

This invention relates to door handles 7 which are particularly adapted'for use on automobiles.

An object of the invention is the provision of a door handle which may be looked a ainst operation either by a key exteriorly the automobile or which may be locked against movement interiorly of the automobile in the usual manner, but which will per- 10 mit the handle to be rocked without lacing any strain upon the locking mechanism.

A further object of the invention is the provision of a door handle having co-operating means upon the usual operating bolt for a lock so that the handle may be rocked for releasing the usual catch for holding the door in position but the handle may be rockedwhen the catch has been set to prevent opening of the door so that where unauthorized persons would attemptto open the door when the same has been locked, the handle will be permitted to be rotated without injury to the locking mechanism.

This invention will be best understood 25 from a consideration of the following detailed description, in view of the accompanying drawingforming a part of the specification; nevertheless, it is to be understood that the invention is not confined to the disclosure, being susceptible of such changes and modifications which shall define no material departure from the salient features of the invention as expressed in the appended claims.

verse passage in the door in which is rocks ably mounted a barrel 18 from .which projects an integrally, formed hand-grip 19; The barrel 18 1s hollow and a ocket extends ignment with the hollow passage inthe barrel 18 to receive alock 20 which has the usual key-slot 21 to receive a key that controls a lock for preventing operation of the usual bolt of The barrel 18, as shown in dotted lines in Fig. 2, is provided with a longitudinal passage or chamber 23v which receives the usual operating bolt 24. This bolt extends through the bearing 17 in the door'16 and is provided with a squared portion 25 which is connected with a locking mechanism for releasing the bolt of the look when the handle 19 is operated to open the door. However, when the operating bolt 24 is locked against movement either by the lock 20 or by some form of lever associated with the door and located interiorly of the car, the handle 19 will be held against rocking or rotative movement. It Wlll be appreciated that where unauthorized persons attemptto enter a car and they find that it is impossible to operate the handle 19 because of the locked condition of the door, such persons will apply sufficient force to the handle to rock the same against thelockin mechanism and thereby break certain o the elementsconnected with the mechanism, mak' ing it necessary for the owner'tosupply an entirely new equipment. In the present case the handle 19 will be permitted to be rocked or rotated after the door has been locked without causing any injury to the mechanism of the locking device.

The inner end of the barrel 18 is provided with spaced notches 26 and similarly constructed lugs 27 which engage respectively lugs 28 and notches 29 in an adjacent or co-operating end of a sleeve 30 which is mounted on the operating bolt 24 and maintained in contacting relation with theinner end of the barrel 18 by means of a coil spring 31 embracing the locking bolt and held in place by means of a nut 32 threaded on the outer end 33 of the locking bolt 34.

The nut can be adjusted for varying the tension of the spring 31 on the sleeve 30.

The sleeve 30 is provided on the sleeve 35 which receives a set screw 36 threaded 5 into a passage in the operating bolt 24. A

washer 37 is received by the bolt 24 and is engaged bythe inner end of the spring 31.

The set screw 36 in the slot 35 permits the sleeve to be shifted longitudinally of the 1 locking bolt 24 but to be held against rotailalivlez1 movement whenever the locking bolt is The barrel 18 is provided with pins 40 diametrically disposed which have their inner ends received within an annular groove having complementarily formed .lugs and notches interfitting with the notches and lugs on the barrel, a nut threaded on the bolt in spaced relation with the sleeve, a coil spring on the bolt between the nut and the sleeve for retaining the lugs and notches in operative relation so that the bolt may be rotated by the barrel when the bolt is free to rotate, a and means connecting-the sleeveto the bolt while providing for sliding movement of the sleeve on the bolt againstthe tension of the spring when the bolt is locked against rotative' movement.

41 in a locking bolt 24, so that the barrel ma be revolved upon the bolt by the pins an prevent reciprocation ofthe barrel on the bolt.

The operation of my device is as follows: 7

It is immaterial whether the operating bolt 24 is locked against rotation by the lock 20 or by an internal locking mechanism which will prevent the normal operation of the handle 19 for releasing the door since the present device will operate equally as well with any of the usual types of locking mechanism for a door.

I If, however, the operating bolt 24 has been 1 locked against movement in some well known manner and an unauthorized person will attempt to open the door through manipulation of the hand-piece 19, the barrel 18 may be rocked or rotated so that the lugs 35 27' on the inner end of the barrel 18 will move outwardly of the respective notches 29 in the sleeve 30 and force the sleeve inwardly against the tension of the. spring 31 until the similarly constructed lugs on the inner end of the sleeve or barrel 18 and the sleeve are restingupon each other. Further rocking. of the hand-grip 19 of the barrel 19 will cause the lugs on one of the elements to slip back. into the respective notches on the other element. It will. be seen that a number of revolutions of the 'handle'19 may be made without in any way affecting the rocking of the rod or placin any strain on the bolt 24. e

The tension of the spring 31 is sufiiciently clear to maintain thelugs and notches of the sleeve 30 respectively engaged with the notches and lugs on the inner end of the bar-rel 18 so that the handle 19 may be revolved and likewise the sleeve 30 is rotating the operating bolt 24 to release the usual locking bolt of the lock when the locking device has been released.

I claim: I u A handle for doors comprising an operating bolt adapted to be locked against rotation, a barrel rotatable on the bolt and provided on the inner end with alternately disposed notches and lugs, a sleeve on the bolt located externally of the barrel and
