The swinging end |32 of said spring is adapted to bear against either the Aiange |53 or |54. Referring to the modification indicated in Figs. 12, 13 and 14, the disc shaped lock bolt similar to 33, is indicated at 03a. Tapering projections |00 extend from one face of the bolt 33a and similar oppositely positioned tapering projections |05 extend from the opposite face of said bolt. The main member of the housing of the lock b olt similar to 43 is indicated at 49:6. Tapering cavities 14a are indicatedf in the member 492:. The main member of the cover of the housing for the lock bolt 38a is shown at 90a. Tapering cavities 84a. oppositely positioned to the cavities 14a but similar thereto are indicated for the main cover 30a.

In the drawings the door is indicated in its closed position with the lock bolt 33 having its outer face 90 bearing against the vertical face 33 of the locking seat of the keeper 23 as indicated in Figs. 4 and 6.4 In this position the outer face 41a of the main member 43 of the housingl abuts against the stop 39, and the door 40 is securely locked in its closed position and is prevented from rattling. The end |4| of the spiral spring |40 abuts against the heel 94 of the nose 93 of the lock bolt 88 to maintain the latter in locked position. The lock bolt 83 in this position bears against the inner face 33 of. the main member of the cover of the housing of the lock. The balls 99 and 93 at the closed position of the door are respectively located in their cam cavities 14 and 34 as indicated in Fig. 7, that is to say. the balls 99 are at the peaks 11a, and the balls 93 are at the crowns 31.

If the lock is to be opened from the outside, the second operating lever .|50 must be positioned in its lowere'd position as indicated in full lines in Fig. 3, and the operating handle ||4 is turned in the direction of the arrow A, Fig. 1, and thereby the operating lever |00 is swung in the same direction as indicated by the arrow A, Fig. 3.

The ilange |02 of the operating lever |00 will' bear against the nose 92 of the lock bolt 83 and the latter will be turned in the direction of the arrow C, Fig. 3. and the locking nose 9| of the lock bolt 93 rises out of contact with the face 33 `oi. the keeper 23.r` The direction of the movement of the lock b'olt 38 in Fig. l is indicated by the arrow D'. At the same time the balls 98 move from the crowns 81 of the cam cavities 84 to the peaks 31a, and. the balls 33 move from the peaks 11a to the crowns 11 of the cam cavities 14 as indicated in Fig. 8. By the coaction of the b alls with the camcavities 34, as just described, the lock bolt 33 as it swings in the direction of the'arrow C, Fig. 3 moves laterally in the direction of the arrow E, see Fig. 4, and the door 40 can be easily swung open as indicated by thearrow O, Fig. 4.

When the door A4|! is in its closed position the aucuns? tains thev operating lever |00 in its rfised position when not actuated lby the operating handle.

If the second operating lever |59 is located in the position indicated in the dotted lines in Fig. 3, the door' can not be swung open from the outside by means of the operating handle I Il.

After the door is open the tension ofthe spring |40 automatically locates the lock bolt 88 in the position indicated in Fig. 3. When the door is swung to its closed position without the use of thevoperating handle the lock bolt 88 approaches the keeper 28, the bottom face 9Ia of the nose 9| slides up the inclined face 30 and then drops to the inclined face 3| and slides up the latter until seated in the seat having the faces 33 and 34. When the lock bolt 88 is being seated as just described, it swings in a direction opposite to the arrow C, Fig. 3 and opposite to the arrow D, Fig. 7. By the coaction of the balls 96 with the cam cavities 'I4 the said balls 96 move from the crowns Il to the peaks 11a and the door moves laterally in the direction of the arrow E,

by virtue of which the door 4|] is positioned with the outer face 41a of the member 46 bearing against the stop 39. 'Ihe door may also be closed by using the operating handle H4 or |68.

If the door is in its closed position as indicated in Fig. 4 and it is to be swung open from the inside, the operating handle |68 is swung in the direction of the arrow M, Fig. 2, to swing the operating 4lever |50 in the direction of the arrow M, Fig. 3, by reason of which the longitudinal ilange |52 bears against the nose 93 of the lock bolt 88 and the latter turns in the direction of the arrow C, Fig. 3, as already described and the balls 9E and 98 will be positioned with respect to their cam cavities as shown in Fig. 7 as already'described and the lock bolt 88 will move in the direction of the arrow E, Figs. 4 and 6, as described, and will leave the keeper 28 of the lock as described. While the operating lever |58 is swung in thedirection of the arrow M the iiange 353 is bearing against the end |82 of the spring it.

It will be noted that the lock bolt 88 can be positioned with its locking nose in engagement with the locking face 32 of the keeper 28, and in such a case the door Ml will be positioned partly open.v Y

Attention is called to the fact that the mechanism of this invention and especially the means of moving the-lock bolt laterally can be applied to a latch. With the modification indicated in Figs. l2, 13, and 14, the lock bolt 88a is moved laterally by the coaction of the projection with the cavities 14a, and the coaction of projections |U5 with the cavities 84a. v

'I'he door 40 may be constructed in various ways and. in swinging connection with a. stationary structure or with a moving vehicle.

Various modifications may be made inthe invention and the present exemplications thereof are to be considered illustrative and not limitative thereof. Y
