' LOCKING HANDLE FORIJOORS.

Application filed February i7, 19%. Serial no. am.

Ihis invention relates to locking door handles, especially such as are adapted for use on motor vehicles, although the construction of lock disclosed is not by any means 7 limited to use on this type of devices.

In looking door handles of this type as now generally constructed the use of a pin tumbler or cylinder lock requires a relatively wide handle or cross bar in order to secure sufficient room for mounting this type of lock in the handle. In order to overcome this objection handles have been made in which the cross bar is offset so that its center line is placed to one side of the center line oi? the latch operating spindle in an attempt to secure more room. This arrangement allows the use of a somewhat narrower cross bar but is objectionable as being unsymmetrical and even with this arrangement a wider handle is required than is desirable. In order to overcome these objections and allow the use of this type of loci: with a narrow handle, and with other objects in view I have devised the construction shown in the accompanying drawing donning a part of this specification, similar reference characters being employed throughout the various figures to indicate corresponding elements. In this drawing,

Fig. I is a longitudinal section through a vehicle door handle embodying my invention, the section being taken substantially on line l1 oi"? Fig. 2.

Fig. 2 is a front elevation thereof.

Fig. 3 is a partial plan view and partial section, the section'being taken substantially on line 33 of Fig. I, and

Fig. 4- is a trontelevation of a portion of the cross bar before the pin tumbler lock cylinder is mounted in position and before the vulcanized covering is applied.

In Fig. l is shown a portion ot' a vehicle door having the usual opening ll there through for passage of the latch operating spindle 12. Ihe latch is not shown as it terms no part of the present invention. The

handle comprises a shank l3 and a cross bar it which terms the grip "for operating the latch. 'Ihe shank 13 extends through and is mounted-to turn in a suitable escutcheon l5 which is secured to the taco oi the door by suitable screws passing through the openings 16.

In this type of handleit is preferred to have the hey opening in the outer wall or face of the cross bar 14: as this is more convenient and provides a neater appearance. In the old construction, however, either some special form of lock was required on account of the limited space available for mounting it, or it a pin tumbler or cylinder look was used, which is the more desirable look as it is safer andemploys arelatively small flat key, a relatively large cross bar was required to accommodate this look because of the lateral arrangement of'jthe, pin tumblers, or the-cross bar had to be ofl'set with respect to the axis oil the spindle. With my present construction I overcome both of these objections and employ a pin tumbler or cylinder lock with the narrow type of handle and without ofisetting the crossbar.

In this construction a pair of openings 1? and 18 are drilled in the handle from the outer wall of the cross bar and. extending in a direction longitudinally of the shank 13 or spindle l2. Ihese two openings are arranged so that they communicate with each other and overlap to some extent as shown in Fig, l. A .plug 19 is mounted in the opening 18 which plug is provided -with transversely drilled openings20 for mounting the pin tumbler springs 21 and drivers 22 for thepin tumblers 23, and thd side of the plug 19 toward the cylindrical opening 17 is grooved as shown at 24 to form a corn tinuation of this cylindrical opening. The plug may be mounted in the handle with a forced tit, but I also preferably provide a securing pin 25 extending transversely through the body of the handle and the plug to prevent this plug working loose and moving out of the correct position. The pin tumbler lock cylinder 26 ie mounted in the cylindrical opening 17 and is adapted to rotate therein, and it has lateral openings for the pin tumblers 23' which cooperate with the notches in the sides of the key 27 in the usual and well known manner of this type of lock. Adjac :nt its inner end the cylinder is provided with an annular groove in which the ends oi securingpins are seated to retain this cylinder in the handle and at its inner end the cylinder is provided with a lug 29 having a lost motion connection through a block 30 with the locking bolts 31 for. operating the same as the cylinder is rotated by the key. This bolt is mounted to slide laterally in the It to project one end in one of a series of notches 32 in the escutcheon 15 to lock the handle against rotation. After the plug 19 and the securing pins 25 are mounted in position the hard rubber or similar material 33 may be applied to the handle for the finishing effect. This material, as indicated, will conceal the pin 25 and the plug 19.

It will be apparent from the foregoing description that as the pin openings 20 in the plug 19 are relatively short they may be very accurately drilled, so that there is no difficulty in mounting the pins in proper position in the handle. Also as the plug 19 requires a relatively small space and may be mounted on any side of the cylindrical opening 17 it may be mounted either above or below this opening in a direction longitudinally of the cross bar as indicated, and therefore, the cross bar need be of no greater width than is required for mounting the pin tumbler lock cylinder 26. This construction allows the use of a pin tumbler or cylinder lock in the narrow type of handle, and furthermore, as will be apparent, there is no necessity of offsetting the cross bar 14: of the handle with respect to the shank 13 or spindle 12.

Having thus set forth the nature of my invention, what I claim is:

1. In combination, a door handle having a pair of overlapping cylindrical openings therein, a pin tumbler lock cylinder mounted to turn in one of said openings, a cylindrical plug mounted in the other opening at one side of said first opening and forming a holder for pin tumblers to coact with said cylinder, a movable locking pin, means coacting with the pin to lock the handle, and

an operative connection from the cylinder to said pin. r

2. In combination, a door handle having a drilled opening therein, a plug mounted in said opening, pin tumblers mounted in said plug, said handle being also provided with a cylindrical opening overlapping and formed partly in the plug, a pin tumbler lock cylinder mounted to turn in said cylindrical opening and coacting with said pins, and a locking bolt controlled by said cylinder.

3. In combination, a door handle comprising a shank and a cross bar, said cross bar being provided with a drilled opening lead ing from the outer wall thereof, a plug mounted in said opening, pin tumblers mounted in said plug, said bar being also provided with a cylindrical opening leading from said outer wall which overlaps and is formed partly in the said plug, a pin tumbler lockcylinder mounted to turn in said cylindrical opening and coaeting with said pins, and a locking bolt controlled by said cylinder.

4. In a look a body member provided with a drilled opening leading from one wall thereof, a plug mounted in said opening, pin tumblers mounted in said plug, said body member being also provided with a cylindrical opening leading from said wall which overlaps and is formed partly in said plug, a pin tumbler lock cylinder mounted to turn in said cylindrical opening and arranged to coact with said pins, and a locking bolt controlled by said cylinder.

5. In combination, a door handle having a shank and a cross bar, said handle being provided with a cylindrical opening leading from the front wall of-the cross bar and extending in a direction longitudinally of the shank, a plug mounted in the handle extending substantially parallel with said opening at one side thereof, said plug being provided with a groove in one side thereof forming a continuation of said opening, pin tumblers mounted in said plug, a pin tumbler lock cylinder mounted to turn in said opening and arranged to coact with said pins, and a locking bolt controlled by said cylinder.

6. In combination, a door handle having a shank and a cross bar, said handle being provided with a cylindrical opening leading from the front wall of the cross bar and extending in a direction longitudinally of the shank, a plug mounted in the handle extending substantially parallel with said opening at one side thereof, said plug being provided with a groove in one side thereof forming a continuation of said opening, a securing pin extending transversely into said plug, pin tumblersmounted in said plug, a pin tumbler lock cylinder mounted to turn in said opening and arranged to coact with said pins, a locking bolt controlled by said cylinder, and a hard vulcanized covering on said handle concealing said securing pin and said plug.

In testimony whereof I affix my signature.

JOSEPH GOODMAN.
