.application filed February The invention relates to a door handle having embodied therein a lock for the door; and the object of the lnvention generally stated is to produce a handle lock which is simple in construction, effective in operation and capable of being manufactured at a low cost.

' More specifically the invention has for a primary object the provision of a lock in a door handle which is adapted to mterengage with the door proper in the operatlon of locking the door in closed position. x 7

Another object is the provision of a lock which in the lockingposition is adapted to interengage with the door proper to prevent its removal from the door.

A further object is to provide a construction for the handle which lends itself readily to the incorporation therein'of the look.

In the accompanying drawings, I have illustrated a preferredembodiment of my invention, but: it should be understood that it iscontemplated that various changesimay be made in the construction and arrange ment set forth without departing from the spirit and scope" of the invention asexpressed in the appended claims.

p My improved handle comprises a tubular stemgenerally designated by the numeral 7 and h a.vingragidly secured at its outer end a cross bar 8. The stem is constructed in the form of two metal stampings providing two inter-fitting sections 9 and'9, for convenience in assembling the locking means. The two halves have interfitting tongues'and notches Figure 1 of the drawings is a fragmentary 5, 1926. Serial No. 86,115.

two sections are thus secured together by the

inter-fitting tongues'and notches

10, 10 and by the bar 12 connecting "the wing portions 11, thus forming the tubular stem 7 and cross bar 8.

At the other or inner end of the stem the two sections 9 and 9 are extended to form arms 13 between which the square lockoperating rod or shank 14 is entered. These arms are preferably channel shaped as shown at 15 (Fig. 6) so as to iit the shank 14 snugl and the parts are rigidly secured together by rivets 16. r

A suitable shell or covering 17, formed from either pressed metalor a moulded composition such as rubber or bakelite encloses the stem 7 andcross bar 8. 1

18desi'gnates a portion of an automobile door having a frontv panel 19 provided with a hole 19 of substantial size opening into a recess or chamber 18 in the door. Opening rearwardly from the chamber 18 is a hole 20 through which the rod or shank 14 extendsi'or operative association with the usual latch (not shown). An .escutcheon plate QL'prei'erably in the form of ametal stamping, encircles the stem 7 of the handle and. is secured to the door by means of screws 22. This .escutcheon plate forms with the panel a cl'iamber 23 for enclosing a part of the locking means. i l i V a I The locking means comprisesa pivoted member or pawl 24 mounted on one of the rivets 16 within a slot 25 formed in the outer end of the latch-operating shank 14, and movable within a hemispherical portion of the recess or chamber 18. Said pawlhas a tail piece 26 projecting from one side of the stem between the arms 13, and this tail piece of the pawl is adapted to be moved into and out of engagement with the door to lock the handle against, turning. Herein the tail piece 26 is arranged to engage in a notch 27 formed in the panel 19 at one side of the aperture 19. 1 The means for operating the pawl 24 may comprise a key-operated cylindcrxlock 28 of ordinary construction mounted within the tumblers normally engaging in slots 28 in the stem. At its inner end the cylinder has a disk 29 carrying an eccentric pin 30 which engages in a notch 31 formed in the forward edge of the pawl .24, the latter as shown in Fig. 2 being of substantial thickness. The arrangement is such that when the cylinder 28 is turned by means of a key, the pawl swung to carry its tail piece 26 either into or out of engagement with the notch 27 in the panel. Obviously, when thus engaging in the notch 27, the handle is positively locked against turning.

As may be seen in Fig. ,3, one side, 14?, of the split shank 14 is preferably formed somewhat longer than the opposite side, 14", to provide a stop against which the eccentric pin '30 is adapted to abut. This abutment insures that in either locked or unlocked position of the pawl the eccentric pin will be positively in engagement with the notch 31 in the pawl. The shorter side, 14 of the shank permits the passage of the pin 30' in the locking and unlocking movement thereof. To prevent the handle trombeing removed from the door when locked, I also utilize the pawl 2 1. For this purpose the pawl has a transverse pin 32 which in the locked position of the door engages with the inner side of the panel at opposite sides ofthe notch 27 of the aperture 19. Thus it will be seen that the pawl not only locks the handle against turning,but effectively prevents the removal of the handle from the door rendering unnecessary the use of the usual fastening means in the end otthe handle shank. To prevent withdrawal of the handle from the door when the pawl is in its unlocked positioml provide a collar 33 rigidly secured to the arms 13 on opposite sides of the shank 14, as by means of a pair of wings34 which are fastened by the rivet 16 which forms the Y pivotal axis of the pawl 24:. Bet-ween this collar and the escutcheon plate 21 is a stilt coiledspring 35 acting to hold the inner end of the shell 17 ot' the handle in operative relation to the OTCH'tChGOH plate and thereby retaining the handle in the door.

The construction provided is, it will be seen, extremely simple employing few parts and capable of manufacture at small cost and capable of being quickly and easily assembled. T-he locking pawl is firmly secured to the handle and by engaging with the door proper serves eiiectually to hold the handle against turning-and to prevent itsremoval from thedoor. r

I claim as my invention:
