DOOR LATCH.

Application filed February This invention relates generally to latches designed particularly for use with vehicle doors and consists of certain novel features of construction, combinations and arrangements of parts as will be more fully de scribed and particularly pointed out in the appended claims.

in the accompanying drawings;

Figure 1 is a horizontal sectional view through a vehicle door with a latch embodying my invention attached thereto.

Figure 2 is a perspective view ofthe latch.

Figure 3 is another perspective view of the latch.

Figure is a side elevation of the latch with. the outside cover plate removed.

Figure is a side elevation of the latch with the inside cover plate removed.

Referring now to the drawings in which like characters of reference designate corresponding parts throughout the several views, the numeral 1 designates a door, preferably of a vehicle body, having a pillar 2 provlded at its inner edge with a channel-shaped portion 3 which constitutes a run-way for a ver tically movable glass panel 4-.

In order that a latch may lie-mounted and operated upon the pillar 2 without interfer- .ing with the vertical movement of the glass panel i, 1 preferably provide a case plate 5 that is preferably U-shape in cross section and that preferably straddles the channel-shaped guide-way 3. As shown, the inner section 6 of the case plate preferably supports a swingingly mounted latch bolt 7 and the mside operating means therefor, while the outer section 8 preferably supports the outside operating means for the bolts.

In detail, the bolt 7 is preferably stamped from sheet metal and is provided with an upstanding shank portion 9 and a forwardly extendinsr head 10. As shown, the shank 9 is preferably provided at its lower end with hub 11 that is journaled in aligned openings in the inner case plate section 6 and cover plate 12 secured thereto, while t-he head is preferably beveled at its outer end and 1s adapted to engage a suitable keeper 13 upon a door iamb of the vehicle body.

In order that the bolt may be retracted from either the outside or the inside of the door, the shank 9 is preferably provided at diametrically opposite points of the hub 11 with torwardly andrearwardly extending 16, 1925. Serial no. 9,685.

arms 14 and 15 respectively which are adapted to be actuated by a roll back 16 upon the outer section 8 of the case plate, and a lever 17 upon the inner section 6 of the case plate. As shown, the roll baclr 16 has a hub 18 journaled in aligned openings in the outer case plate section 8 and cover plate 19 secured thereto and is provided at its forward edge with a lateral extension 20 that extends across the transversely extending portion 21 of the case plate, and is normally engaged by a corresponding lateral extension 22 of the arm 14. Any suitable means may be engaged with the square opening 23 in the hub 18 for rocking the roll-back 16 so that the lateral eXtension 20 thereof will raise the lateral extension 22 of the arm 14 and cause the latter to retract the bolt. The lever 17 normally engages suitable spaced lugs 24 and 25 respectively on the forward edge of the arm 15 and is preferably provided at its lower end with a flat rounded head 26 that is pivotally mounted on the inner section (3 of the case plate between the shank 9 and rearwardly extending arm 15. Any suitable means such as the helical spring 27 engaging the rearwardly extending arm 15 may be employed for normally holding the bolt head 10 in projected position and also for holding the lateral extension 22 of the arm 14 in operative posi tion with respect to the lateral extension 20 of the roll-back 16. Thus, with this construction, the roll-back 16 may be actuated from the outside of the door to retract the bolt without affecting the lever 17 and the latter may in turn be swung to the rear against the arm 15 without affecting the rollback. In order that the outside operating means may be rendered inoperative from the outside of the vehicle, I preferably provide a dog 28 that is pivoted on the outer section 8 of the case plate and is adapted to swing behind a lug 29 on the roll back 16 to prevent the upward swinging movement of the extension 20. This dog 28 is normally held out of the path of the lug 29 against the struck out lug 80 on the case plate section 8 by means of a coil spring 31 anchored on the case plate section 8 and may be moved by any suitable means into operative dogging position. As shown, the dog 28 is preferably actuated by a suitable cam 32 rigidly secured to the rotatable cylinder 33 of an auxiliary lock 3% which is preferably anchored. in a tubular housing 35 projecting laterally from the cover plate 8 and any suitable means such as the screw 36 threadedl Y en a m the laterall attachin b b a: V a

flan 'e 39 of the case Jlate ma be em lo ed .forholding the lock 3d within the housing 35.

In order that the outside operating means may be rendered inoperative from the inside of the door, 1 preferably provide a dog- 10 that is adapted to be moved by the inside operating lever 17 into operativedogging' position behind a shoulder 11 of the boltshank 9 for preventing the bolt from being retract- "edfro'inthe outside of the door. As shown,

this dog 40 is preferably pivoted on a pin 42 anchored upon the-inner section 6 of the case plate and is normally held outof the pathof the bolt shank by means of a suitable spring a3 secured to the case plate section 6. More- 'overthe forwardly extending portion 10 of the bolt is provided'at its upper edge with a recess portion 4.4 to receive the dog 10 when" the bolt is retracted. W'ith this construction, the dog may be detachably held in operative dogging position by means of the lever 17. As shown, a suitable leaf spring is' anchored upon the inner face of the cover plate 12 andis provided at one end with an inwardly extending rib 46 that is engageable with a suitable depression 47 in the outer face of the'lever 17 when the latter is in its for whereu Jon the sarin 18 will automaticall t) move the dog 10 upwardly out of the pathof the shoulder 4-.1. The roll-back 16 may then be operated from the outside of the door if desired for retracting the bolt. I

To prevent the lever 17 from rattling, 1 preferablyprovide a suitable spring a8 that is anchored upon the inner section 6 of the case plate and consequently holds the lever 17 against the spring-pressed dog 40 and rib 46 of the'leaf spring -15. Thus, the spring 4-3 as well as the sprin g cooperates with the spring 18 for normally holding the lever 17 against rattling.

From the foregoing descriptlon, it will be readily apparent that a latch of this type may be mounted upon a' door pillar having a very small cross section, consequently the vision of the occupants of the vehicle'is materially' increased. Moreover, the arrangement is such that the bolt 10 may be retracted from the outside of the door without interrupting the vertical movement of the glass panels. It will also be'apparent that the outside operating means may be operated independently of the inside operating means for retracting the bolt. It will also be noted that the inner cover plate 12 cooperates with the inner section 6 of the case plate for holding the lever 17 in proper position between the shank 9 and arm 15. Moreover, a lug 50 is provided upon the roll-back 1G for engagement with a struck out lug 51 on the outer.

section 8 of the case plate for limiting the downward swinging movement of the rollback 1 6.' Inasmuch as the spring27 normally urgesthe bolt 10 forward, it will be readily apparent that the forward swinging movement of the bolt is limited by the engagement of the lateral extension 22 with the lateral extension 21 of the roll-back 16.

While it" is believed that from the fore going description the natures and advantages of my invention Will be readily apparent, l
