DOOR LOCK Filed Aug. 4. 1930 '3 Sheets-Sheet 3 TTTTTT EY Patented July 26, i932 UNITED STATES PATENT OFFICE This invention relates to a lock whichis v mainly designed for use in connection m'th the doors of motor vehicles, though the invention is not to be limited to any particular use, the general object of the invention being to provide means whereby the handle of the lock can be pushed into a recess in the lock face or in a recess in the door itself so that the handle willbe out of the way and will prevent movement of the handle to open the door and the possibility of obtaining a hold on the handle with the hands, fingers or tools in an attempt to tamper with .or .destroy the locking mechanism.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawin s and specifically pointed out in the appen ed claim.

In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughoutthe several views, and in which Figu showing the improved lock m use.

Figure 2 is a view of the iImer face of the door with the lock thereon.

Figure 3 is a section on line 3-3 of Figure 1.

Figure 4 is a similar view but showing the handle pushed into the recess.

Figure 5 is a section on line 5-5 ofFigure 3.

V Figure 6 is a section on line 66 of'Fig ure 3. Figure 7 is a view ofthe cylindrical member for transmitting the'turning movement of the handle to the bolt.

Figure 8 isa view of the cam carrying member.

Figure 9 is a sectional view through the handle and its shank.

. In these drawings,-the numeral 1 indicates the late which is fastened to the outer face of tlie door A, which is shown as tL-d door of a. motor vehicle. The major portion of the plate fits in a recess in said face of the door and this portion of the plate is formed with 7 end of the lock barrel. re 1 is afragmentary view of a door,

a recess 2'. A cup-shaped member 3 is rotatably arranged in the other or inner face of the door and carries a cam 4 for engaging a recess 5 in the bolt 6 of the door and a cylinder 7 is placed between the plate 1 and the member 3 and has one end rotatably arranged in the annular flange 1 formed on the inner face of the plate 1 and its other end is formed with the notches 8 for receiving the projections 9 on the member 3. The opposite end of the cylinder 7 is also formed with the notches I0 and intermediate its ends the cylindrical member is formed with a hole 11.

A handle 12 is provided with a shank 13 which passes through a hole in the plate 1 and extends into the member 7 and said shank has a pin 1 passing therethrough which has its ends engaging the elongated slots '15 in the member 7 so that the member 7 will be turned when the handle is turned.

A lock barrel 16 is mounted in the shank and handle and is held therein by a pin 17 engaging an annular groove 18 in the reduced the barrel is provided with an eccentric pin 19 which engages a hole in a lock bolt 20 slidably and transversely arranged in the inner end of the shank so that when the barrel is turned by a key, the lock bolt 20 is projected and retracted. This latch bar can be projected to engage the notch 10 to hold the handle in its outer position, as shown in Figure 3, or it can be retracted and the handle pushed inwardly and then the lock bolt rojected into the hole 11 to hold the hand e in the recess 2, as shown in Figure 4.

A spring 21 is placed in the member 7 and has one end seated in the member 3 and its other end bearing against the inner end of the shank 13 so that the spring tends to hold the handle in its outer osition, as shown in Figure 3. The bolt 6 1s normally held in its projected position by a spring 22, as shown m Figure 2.

From the foregoing it will be seen that the bolt 6 can be moved inwardly into inoperative position when the handle is in its outward position, as shown in Figure 3, due I to the fact that the lock bolt 20 engages the The inner end of notch 10 in the member 7 for as the handle is turned, the lock bolt 20 W11]. cause the member 7 to turn and the turning movement of said member 7 is communicated to the member 3 through the engagement of the notches 8 with the projections 9 so that said member 3 will be turned and thus cause its cam 4 to engage the bolt 6 to retract the same. By pushing the handle inwardly after the 10 lock bolt 20 is retracted and then projecting the latch bar into the hole 11, the handle is held in the recess 2 so that-it will be out of the way and it will be impossible to mani ulate the handle in an attempt to nnloclic t e door. The usual means can he provided for opening the door from'the inside and I place a gasket 23 in a groove in the shank receiving opening of the plate 1 to eliminate any tendency to rattle when the handle 12 is extended or depressed.

It is thought from the foregoing descrip tionthat the advantages and novel features of the invention will be readil apparent.

' It is to be understood that c anges may be 25 made in the construction and in the comloination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.

What I claim is In combination, a recessed plate mounted within the outer face of a door and having an annular flange at its inner side, a cup shaped member rotatably arranged at the inner face of said door and having a cam, a

sliding bolt within the door and engaged by said cam, a cylinder fitted within the am nular flange and having notched ends and an intermediate hole, a handle having a shank passedthrou h the plate and slidably fitted in said c lin er to permit the handle to move into an out of. the recess in said plate, a cross pin mounted in the shank and slidably engaged in the cylinder, a lockbarrel in the she an operatin lock holt controlled by said lock barrel and engageable either in the 7 hole or the notch at the outer end of the cylinder, and a lu on the cup-shaped member engageahle wlth the notch in the inner end of the cylinder. 59 In testimony whereof I afix my signature.
