Referring to the drawings and first to Figs. 40 l to 8 inclusive, the automobile body I has a usual or suitable door 2 swinging on vertical hinges 3. Mounted in the door is a suitable casing 4 within which is mounted a latch bolt 5, an opening bol-t B and'a closing bolt 1 which 45 slide in suitable orices in the casing 4 and engage with the striker plate 8 mounted upon the door jamb 9. The latch bolt and opening and closing bolt-s are operated by an arm I0 mounted upon a shaft II journaled in the casing and having a', square section i2 which engages in. a square hole in the arm IU to prevent relative turning. The arm I0 extends on both sides of the shaft and forms in effect two angularly displacedv arms. To the inside end of the shaft n is exeal the arm la by willen the shaft; Il may be turned. The arm I3 may be connected by suitable linkage I4 with a, handle I5 so as to be operated from a distance at a more convenient location. The outer end of the shaft Il has fixed to it the handle I6 for turning the shaft from the ex-terlor of the door. The latching bolt 5 tends to be forced into extended position by reason of a coiled spring I1 having one end secured to the pin I8 fixed in the casing 4 and the other end of the spring engaging with -a pin I9 fixed on the latch bolt 5. The outward movement of the latch bolt under the iniiuence of the spring is limited by the pin I9 coming against the. casing i.

In its extended position the nose of the latch bolt engages in the notches 26 and 2| in the striker plate 8, the notch 20 being adapted to receive the nose of the latch bolt and hold the door when the last has not been completely closed, while the latch bolt nose engages in the notch 2| when the door has been approximately completely closed. As is usual with latch bolts the outer face of the nose of the latch bolt is flat and adapted to be opposed by abrupt shoulders on the striking plate to prevent opening of the door without retracting the latch bolt, while the rear face of the latch bolt and nose is beveled andthere are corresponding beveled faces on the striker plate to cause the latch bolt to be automatically retracted and snap into the notches of the striker plate as the door is closed.

The latch bolt 5 is retracted against the spring I1 by the arm I0 operating on it through the closing bolt 1. The closing bolt 1 has xed upon it a pin 22 which is embraced within the fork formed by the projections 23 and 24 at the upper end of the arm I0. The turning of this arm in the direction as indicated by the arrow (Fig. 2) will cause the bolt 1 to be retracted and bear against the upstanding projection 25 upon the latch bolt 5 whereby the latch bolt will be retracted along with the bolt 1 until its full retractive position is reached as shown in Fig. 4.

The opening bolt 6 is retracted and extended by means of the pin 26 fixed in the bolt and extending into the recess 21 in the end of the arm II). In the position as shown in Fig. 2 the opening bolt is in retracted position as is also the closing bolt, while the latch bolt is in extended or securing position. In the position as shown in Fig. 4 the movement of the arm in the direction of the arrow has withdrawn the latch bolt to its retracted position but the width of the recess 21 has permitted this to be done without moving the opening bol-t 6. In the position as shown in Fig. 4, however, the arm has come against the pin 26 and further movement of the arm in the saine direction, and into the position as shown in Fig. 5, results in the extension of the opening bolt 6 which causes its diagonal outer end face 28 to wedge against a corresponding diagonal face 29 on the striker plate 8 and wedge the door slightly open as shown in Fig. 6. From this position the door is readily opened to the desired extent, any initial sticking or jamming of the door being overgomes by the Wedgng action of the opening olt When the operating force is removed from the handle, the Spring I'I will throw the parts into the position as shown in Fig. 2, so\ that the door will automatically latch in the usual manne when pushed toward closing position.

If now the arm I0 is moved from this position by rotating it by means of one of the handles in the direction of the arrow of Fig. 7 (the opposite to that in Fig. 2), the projection 23 will bear against the pin 22 and move the closing bolt 1 into extended position as shown in Fig. 7, the diagonal outer end face 30 of the bolt coming against the corresponding diagonal face 3| on the striker plate and operating to wedge or cam the door inwardly thereby taking up any possible looseness between the door and its frame, occasioned by Wear or otherwise. This wedging of the door against the frame will securely hold it tightly closed and prevent rattling. The closing bolt is held in its position of wedging the door shut by reason of the fact that the projection 23 of the arm I0 is vprovided with a recess at its end in which the pin 22 lodges (see Fig. '7) when the closing bolt is fully extended and holds it in that position. On reversal of the rotationl of the shaft II, from, the position as shown in Fig. '1., and its movement to the position as shown in Fig. 2 will withdraw the closing bolt, further movement will withdraw the latch bolt and further movement will extend the opening bolt to initially open the door. On the closing of the door the latch bolt will automatically snap into engagement with the striker plate as stated, and when the door has been closed a turning of the shaft Il into the position as shown in Fig. '1 will result in the Wedging of the door tightly against its frame and prevent rattling.

Referring now to Figs. 9 to 16 of the drawings, the casing 4' is mounted in the door 2', the striker plate 8 being mounted on the jamb 9. The apparatus comprises, like the device of the foregoing Figures 1 to 8, a rotatable shaft 32 having a square section 33 entering within a square hole in the arm 34, whereby the arm is turned with the shaft. One end of the arm has the fork formed by the projections 35 and 36 within which is embraced the pin 31 fixed on the sliding bolt 38 adapted to cooperate with the striking plate to wedge the door closed (see Fig. 15), the sliding latch bolt 39 tends to be extended by the spring 40 and is limited in its extended movement by the pin 4I thereon coming against the casing 4', the latch bolt 39 having an upstanding projection 42 at its rear end adapted to be engaged by the rear end of the bolt 38 as the last is moved to the left in Fig. 9, to retract the latch bolt. The other end of the arm 34 has a fork formed by the projections 43 and 44 within which is embraced the pin 45 on the door-opening bolt 46,

the recess between the projections 43 and 44 being of the apparatus of Figs. 1 to 8; instead, however,

of operating handles or levers upon both ends of the shaft 32, there is an operating handle 41 at the outer (outside the door) end of the shaft only, and by means of the handle 41 the parts referred to are operated in the same manner as the similar parts are operated from the handle I 6 of Fig. 3.

To operate the parts from the inner side of the door a separate operating shaft 48 is journaled in the casing 4' and is operated by a handle 49 fixed upon the shaft. Also fixed upon the shaft is the dog 50 which-operates the parts as 75 the shaft 48 is turned and also serves to effect locking of the parts as will appear from-the following:

The dog 50 is held against accidental displacement, but remains in any position to which it may be moved, by means of a coiled spring 3i having one end bearing against the casing 4' and the other against the dog 50. If, from the position of parts as shown in Fig. 9, the handle 49 and its connected shaft 48 and dog 50 are turned in a counterclockwise direction as viewed in that figure, the lower end of the dog will come against the lower end of the arm 34 and move it into the position as shown in Fig. 11 wherein the latch bolt 39 has been retracted. The further movement of the handle and dog in this same direction causes the dog to move the arm 35 into the position as shown in Fig. 12 wherein the dooropening bolt 43 is forced against the striker plate 9', as shown in Fig. 13, and the door is forced open.

If, from the position as shown in Fig. 9, the handle 49 and dog 50 are turned in a clockwise direction, the upper end of the dog 50 will come against the upper portion of the arm 34 and force the same into the position as shown in Fig. 14, at which point the bolt 38 for wedging the door shut will be extended so as to wedge against the striker plate as shown in Fig. 15, and the detent 52 at the upper end of the dog 50 will enter the notch 53 in the arm 34, which will prevent movement of the arm in a counterclockwise direction. Under this condition it will be seen that the bolt 39 engages with the striker plate to lock the door shut, and it can be unlocked only from the interior of the car (by the handle 49) and cannot be unlocked from the exterior of the car (by the handle 41). It will be' seen that the bolt 38 is held in extended and locking position by means of the projection 35, and that therefore the latch bolt 39 cannot be retracted from its locking position. Any attempt by means of the handle 41 to movethe arm 34 in the counterclockwise direction from the position as shown in Fig. 14 will be resisted by the dog 5l).v 'I'he .bolt 38 will thusy be securely held in locking position by theI bearing of the pin 31 against the arm 34 which is in turn locked by the dog'- 50 as referred to. However, the turning of the shaft 48 in a counterclockwise direction from the position as shown in Fig. 15,will result in turning of the dog 50, withdrawal of the detent 52 from the notch 53 and the movement of the arm 34 in such direction as to retract the bolt 38 out of locking position as shown, for instance in Fig. 9, and .further turning of the shaft 43 in the direction as stated wm result in the retraction of me latch bolt 39 into unlocked position ,as'shown in Fig. 11. It is therefore clear that in the manner Just described the door may be locked so thatit may be unlocked from the inside only.

It may be` desirable, las for instance where children are in the car and might accidentally open the door and fall out, to lock the door so that it cannot be unlocked from the inside. To.

accomplish this result the arm 34 may be turned by the shaft 32 in a clockwise direction (Fig. 16) into the position of Fig. 16 where the pin 31 will lodge in the concave seat upon the end of the projection 35 whereupon the locking bolt 38 will be securely held in locking position by the arm 34 forming a strut between the pin 31 and the shaft 32, upward movement of the bolt 39 being prevented by the top of the casing 4' in proximity to which it is. l. Any turning 0i the shaft 4B in al counterclockwise direction in an attempt to move the arm 34out of restraining position would simply result inthe lug 54 at the lower end of the dog 53 being brought against the end of the projection 43 on the arm 34, whereupon the dog and arm would be jammed between their two centers, and the movement arrested. Further movement of the arm 34 in-a clockwise direction is prevented .by the concave portion 55 of the arm coming against the hub 55 oi' thedog 50. Movement of the arm 34 in the counterclockwise direction (Fig. 16) to remove the pin from the concave seat could readily be effected byturning the shaft 32 by the handle 41. The continued turning of the arm would cause the locking bolt' 33 to be retracted by the projection 36 coming against the pin 31 until the bolt is fully retracted and the door unlocked. I

In most of the positions in which the dog 50 may be located, the movement 'of the locking bolt to unlocking position by the continuous turning of the arm 34 is as referred to,as in the majority of cases the detenty 52 would not come into registry with the notch 53 to arrest such movement. In some cases, however. as for instance if the arm 34 is moved into the locking position of Fig. 16 from the-position of parts of Fig. 14, the detent 52 will enter the notch 53 on counterclockwlse movement and the movement will be arrested. It will then be necessary to turn the shaft 48 from the yinside 'to release the arm and permit the completion of the unlocking operation.

While the invention has been illustrated in.

what are considered its best applications it may have other embodiments without departing from its spirit andis not therefore limited to the structures'shown in the drawings.
