1 Claim'.

This invention relates to improvements in multiple door locks particularly adapted for automobile bodies of the commercial type, although not limited to such use.

The principal object of the invention is to provide an improved and simple locking mechanism having a plurality of locking bolts operated by aisingle handle and having a snap action so that the lock will be positively moved either into fully cpe-ned or fully closed position.

Other objects and advantages of the invention will appear from the following description.

rlf'he invention may best be understood by reference to the accompanying drawing, in which Fig, l is a perspective fragmentary view of an automobile body to which an embodiment of my invention has been applied.

Fig. 2 is an enlarged fragmentary side View of the door and lock shown in Fig. 1, with the mechanism in unlocked position.

Fig. 3 is an inside face view of the door and lock shown in Fig. 2.

Fig. 4 is a detail section taken on line 4-4 of Fig. 2, and showing the locking mechanism in locked position.

Fig. 5 is a detail perspective View of the cover plate forming part of the locking mechanism.

Fig. 6 is a fragmentary detail View from the outside of the door showing the locking handle in closed position.

In the embodiment of the invention illustrated in the drawing, I6 indicates the rear door of a commercial automobile body to which my improved locking mechanism is appiled; II, II indicate opposed door frame members having suitable keeper plates I2, I2 in position to be engaged by the end locking bolts I3 and |33; and I4 indicates a suitable abutment adapted to be engaged by a swinging bolt or locking piece I5 at the center of the door. The abutment I4 may be either a fixed door frame member, or the edge of another swinging door having as usual separate latch or fastening means therefor.

The locking mechanism includes an elongated base plate 24J disposed adjacent the inner edge of the door approximately at the center thereof, and a cover plate 2| having its central portion spaced in parallel relation thereto. In the form shown, the plates 20 and 2| are both secured-to the door by bolts 22, 22 at opposite ends thereof. An outer plate 25 is secured to the exposed face of the door, and a shaft 26 having a handle 21 mounted thereon extends through said outer plate, door l0 and base plate 26, and bearing aperture 2|a of the cover plate 2|. (See Fig. 4.)

193s, lserial No- 195,803

A locking piece I5 consisting of a relatively flat rectangular piece of metal is fixed on the inner end of the shaft 26, as by a set screw 28 passing through a boss 29 projecting from the outer face o-f said locking piece I5, as viewed from the interior of the doo-r. It will be observed that the locking piece I5 is pivotally mounted on shaft 26 nearer one end of the base plate 26 and cove:l plate 2|, so that the elongated locking portion I5a of said locking piece may be swung inwardly beneath the cover plate 2| when the locking piece is in unlocked position, as shown in Fig. 3.

The locking piece I5 has a pair of pivot pins 36 and 3| mounted in bosses 36*l and SIE, respectively, disposed at opposite sides and in alignment with the pivotal axis of the locking piece I5 and at an angle of approximately 45 degrees to the longitudinal axis of said locking piece, as clearly seen in Fig. 4. The pins 30 and 3| project beyond the cover plate 2| at opposite sides thereof, in. the form shown herein, the said cover plate having arcuate shaped notches 34 and 35 formed in its opposite edges to accommodate the pins 30 and 3|, respectively, and form stops to limit the pivotal movement of said locking piece. A pair of tie rods 36 and 31 are pivotally mounted on the outer ends o-f pins 30 and 3|, respectively, and extend in opposite directions along the edge of the door to locking bolts I3 and |321. Each of said locking bolts is longitudinally slidable in an elongated guide member 38 secured adjacent the edge of the door I0.

Each of the rods 36 and 31 is preferably connected to its respective bolt I3 and I3a by inserting its outer end in a drilled hole 46 extending lengthwise of said bolt and securing the rod and bolt in proper adjusted position by a set screw 4I. In the form. shown herein, a portion of the side wall of each :guide member 38 is cut away as indicated at 42, to accommodate the set screw 4I carried by the locking bolt as the latter is moved into its extended locking position.

A leaf spring 45 is interposed between the outer face of the cover plate 2| and the inner faces of the rods 36 and 31, and is held in place by pins 36 and 3| which pass through opposite ends thereof so as to swing bodily with the locking piece I5. Said spring 45 is normally flexed outwardly at its ends so as to urge the rods 36 and 31 outwardly and also urge the locking piece I5 toward said plate in order to take up play and prevent rattle of the parts.

The pivotal movement of the locking piece I5 is partially controlled by a coil spring 48 mounted on a guide rod 49, which rod is pivotally connected on pin 50 carried by the locking piece I5, and has its opposite end 4I!a slidably mounted in an aperture 5| formed at the lower shoulder 52 of cover plate 2|.

The arrangement of spring 48 is such that when the locking piece I5 is swung to one extreme position, as for instance in the locking position shown in Fig. 4, said spring and its guide rod 49 are swung therewith to one side of a dead center line extending between the shaft 21 and the bottom end of spring 49 where it engages the shoulder 52. The spring 48 is normally kept under compression so as to urge the locking member into its locked position. When the locking piece is swung by manual operation of the handle 26 to unlocked position, an additional compression is imposed on the spring until the latter passes the dead center line, after which said spring assists in completing the swinging movement of said locking piece into its fully Although I have shown and described one particular embodiment of my invention, it will be understood that I do not wish to be limited to the exact construction shown and described, but that various changes and modifications may be made without departing from the spirit and scope of my invention as defined in the appended claim.

I claim as my invention:

In a locking mechanism, a frame including a base plate spaced in parallel relation therewith and a cover plate, a manually operable control shaft rotatably supported in said base plate, a pivotally movable locking piece fixed on said shaft between said base plate and said cover plate and having a portion thereof swingable into extended locking position beyond said frame, a pair of pivot pins carried by said locking piece and extending on opposite sides of said cover plate, a pair of push rods pivotally connected to said pins and extending in opposite directions from said frame, reciprocably movable locking bolts connected at the outer ends of said push rods so as to be operative simultaneously with said locking piece, and a leaf spring interposed between the outer face of said cover plate and the ends of said push rods and movable with the latter to yieldingly urge said locking piece into bearing engagement with the under face of said cover plate.
