bodying my invention.

Figure 2 is a rear elevation of the latch shown in Figure 1.

Figure 3 is a top plan view of the con struction shown in Figures 1 and 2.

Figure 4: is a view similar to Figure 1 but showing the dog in operative position.

Figure 5 is a view similar to Figure l but showing the position of the parts when the bolt is retracted.

Referring now to the drawings, the numeral 1 designates a latch case plate that is preferably secured to the inner side of a door and is provided at one edge with a laterally extending flange 2 that is secured to the outer edge of the door. Slidably mounted on the case plate 1 is a bolt 3 having a flat shank A and an enlarged head 5. As shown, the head 5 extends through a suitable opening 6 in the lateral flange 2 of the case plate and is adapted to engage asuitable keeper (not shown) upon the door jamb of the vehicle body, while the shank 4 extends between spaced guide lugs 7 struckout from the case plate 1 and is provided at spaced points throughout its length with an upstanding eX- tension 8 and a lateral projection or lug 9. As shown, this shank is adapted to move behind a suitable cover plate 10 and is normally held in projected position by means of a helical spring 11 anchored on the case plate.

For retracting the bolt against the tension of the spring 11 I preferably provide a suit able roll-back 12 that isadapted to be operated from the outside of the door, and a vertical spindle 13 that is adapted to be operated from the inside of the door. As shown, the roll-back 12 is engageable with the forward extension 8 of the bolt shank and is provided with a hub 14 that is journaled in aligned openings in the case plate and cover plate, preferably immediately in rear of the lateral flange 2. Any suitable means (not shown) may be engaged with the square opening 15 in the hub 14 for rocking the roll- 7 back against the extension 8 to retract the bolt. The spindle 13 is preferably ournaled on the case plate 1 between spaced struckout bearings 16 and is provided intermediate its ends with a suitable crank portion 17 that is 1 adapted to be engaged with the lug 9 for retracting the bolt.

Thus, with this construction, the rail-back 12 may be-moved to the rear against the extension 8 to retract the bolt without effecting the spindle 18, likewise the latter may in turn be rotated so that the crank portion 17 thereof will be engaged with the lug 9 toretract the bolt without effecting the roll-back. The spring 11 will always exert a pressure through the lateral projection 9 of the bolt shank against the crank portion 17 of the spindle to hold the latter in operative position, however a supplemental coil spring 19 is preferably provided at the upper edge of the case plate to prevent any objectionable play of the spindle and to take care of any rattling thereof in the bearings 16. As shown, this spring 19 is preferably coiled about the spindle 13' and is terminally secured to the spindle and case plate, so that the spindle will always be held snugly in the bearings 16. In order that the outside operating means may be rendered inoperative from the inside of the vehicle, I preferably provide a dog 20 that is pivoted upon the case plate 1 between the spindle 13 and roll-back 12 and is adapted to engage a lateral portion 21 of the roll-back 12 to prevent the latter from retracting the bolt. lVith the presentinvention the dog 20 is moved into the path of the lateral projection 21 of the roll-back by means of an actuating. arm 22 that is preferably pivoted at its rear end upon the case plate and is pivoted at its opposite or forward end to the dog 20. In order that the dog 20 may be rendered effective by the manipulation of the inside retracting means the spindle 13 is mounted for rectilinear movement in the bearings 16 and the actuating arm 22 is preferably provided with a longitudinally extending slot 23 that receives a ring or washer illrigidlyauraliioihupiullc'13ubouiln crank portion 17. Thus with this construction, the spindle 13 may be pressed down wardly by means of a suitable handle (not shown) so that the washer 24; will swing downwardly the arm 22 which in turn will lower the dog 20 in rear of the lateral projection 21 of the roll-back 12.

In order that the dog 20 may be rendered ineffective automatically upon the rotation of the spindle 13 to retract the belt, I preferably mount upon the pivot 25 connecting the arm 22 to the dog 20, a suitable roller 26 that is adapted to travel upwardly along the upper edge or" the extension 8 when the bolt is retracted. Hence, the curved upper edge of the extension 8 will serve as a cam for the roller 26 and will cause the dog 20 to be raised out of the path of the shoulder 21 of the rollback when the bolt is retracted (see Figure 5). This upward movement of the dog 20 will cause the arm 22 to move upwardly and to simultaneously lift the spindle 13, to normal or neutral position as shown in Figure 1 oi the crawing.

If desired the dog 20 may be rendered inettfective by the manipulation of the spindle 13. This may be accomplished by merely lifting the spindle 13 by its handle from the lowered position shown in Figure 4 t0 the raised position shown in Figure 1.

From the foregoing description it will be readily apparent that the spindle 13 may be operated in either raised or lowered position to retract the bolt. When the spindle is lowered to actuate the dog the washer 24 will engage the rounded projection 26 at the lower edge of the slot 23 in the dog actuatin arm 22. On the other hand when the spindie 13 is raised by manipulation of its handle the washer 24 will engage the rounded projection 27 at the upper edge 01": the slot in the dog actuating arm 22. hen the dog 20 is raised automatically by engagement of the shank extension 8 with the roller 25, the pro jection 26 at the lower edge of the slot 23 in the arm 22 will engage the washer 24-. on the spindle 13 and will raise the latter to normal position. Inasmuch as the arm 22 is mounted upon a fixed pivot 28 and the dog 20 is limited in its upward movement by the engagement of the rearward extension 29 with the upper case plate bearing 16. it will be apparent that the slotted connection between the arm 22 and the spindle 13 will necessarily limit the rectilinear movement of the spindl'. If desired, the spindle 13 may be do tachably held in raised position by means of a suitable leaf spring 30. As shown, this spring 30 is preferably anchored upon the back of the cl se plate 1 and is provided at its lower end with a returnbent inwardly projecting finger 81 that is engageable with an annular recess 32 in the spindle 13 adjacent to the lower end thereof.

Whileitislrlievcil.that;tunHalon l I i going description, the nature and advantages of the invention will be readily apparent, I desire to have it understood the.
