LATCH.
Application led Hay 8,
The present invention relates to an improved automobile door latch, and has lfor an object to provide a latch of this character, having both an inside and an outside operi ating handle, and in which the outside handle may be rendered ineiective in its operation by means controlled from .the inside. The latch is especially `adapted for use upon doors of closed cars, being applied to all but one of the doors, and which latter is adapted to be locked from the outside.
/Heretofore it has been the practice to lock the outside handle, or the latch bolt, against movement, either through manipulation of the inside handle, or lthrough separate inside locking means, so that by4 exerting a.
suliicient force upon the locked outside handle the locking means could be forced or broken, and the latch bolt retracted to open the door. It is proposed, in the present emloodiment of the invention, to render operation of the outside handle ineffective to operate the bolt, without locking it against turning, however, and which cannot be forced to eiiect retraction of the bolt. A further object is to provide a latch in which the outside handle is rendered ineffective through a movement of the inside handle in reverse direction to the normal retracting movement, so that in order to restore the operative relation of the inside handle, it is only necessary to move the inside handle in its normal retracting direction. Y
Another object is to provide a latch construction in which the inside handle mechanism is adapted to operate directly with'the bolt independently of the outside retracting means, while the outside handle mechanism operates u on the bolt through an intermediate mem er.
It is particularly proposed, in the present embodiment, to provide a latch including a latch bolt having a retracting element normally engaged with the outside handle rollback, and which is adapted to be disengaged therefrom through manipulation of the inside handle to `render operation of the outside handle ineective. "a l With the above and other objects in view, an embodiment of the invention is shown in the accompanying drawings, and this embodiment will be hereinafter more fully described with reference thereto, and the in- A ventionwill be finally pointed out in the claims.
1926, Serial No. 107,542.
In the drawings:
Fig. 1 is a plan elevation of an automobile door latch, according to the present embodiment of the invention, and showing ythe same in its normal operative relation; Fig. 2 is a transverse sectional view,ftaken along the line 2--2 of Fig. 1; y Fig. 3 is a longitudinal sectional view, taken along the line 3-3 of Fig. 1;
Fig. 4 is a plan elevation, with the Vcover plate removed, and showing the parts in the relation in which operation of the outside handle is rendered ineffective;
Fig. 5 is a transverse sectional view, `taken along the line 5-5 of Fig. 4; and
Fig. 6 is a perspective view of the outside handle retracting element employed.-
Similarreference characters indicate corresponding parts throughout the several figures of the rawings.
Referring to the drawings, the embodiment of the invention shown therein comprises a sheet metal `iframe or base plate 10 having a face flange 11 bent therefrom at one end, in which a rectangular opening 12. is i provided, a lip flange portion 13 of the metal cut from the opening being bent inwardly in parallel spaced relation to the plate 10 to form a bearing for the latch bolt.
The latch bolt 14 is slidably engaged at its relatively thick nose portion 15 in the opening 12 and near its inner end is engaged by guide flanges 16 and 17 struck up from the plate 10, and adapted to guide the bolt in its longitudinal movement, a coil sprin 18 being engaged with the inner end of sai bolt and normally pressing it to its projected position.
The bolt is retained against displacement by means of a lat cover plate 19, flanged at its upper and lower edges, as at 20, and secured to the plate 10 by lugs 21 inserted through slots 22 inthe plate 10 and bent over upon the outer surface of said plate.
The latch bolt has formed upon itsouter surface a pair of transverse ribs 23 and 24, the rib 23 being spaced with relation to .the inner surface of the nose 15, and the rib 24: being spaced with relation. to theinner end of the bolt.` and being respectively enga d in slot openings 25 and 26 in lthe cover p ate The inside handle roll-hach 2? is adapted to engage directly with the rib 24, its 4hub 28 being rotatably supported in apertures in 110 the plates 10 and 19, and being movable in lcollinter-clockwise direction to retract the The outside handle roll-back 29 llas its hub 30 rotatably supported in apertures in the plates 10 and 19, and normally engages the upper end portion 31 of an intermediate gate member 32 hingedly connected at its lower end to the latch'bolt, being provided for this purpose with bent hinge forming ears 33 and 34 engaged about a shaft 35 secured at its ends in the inner end of the nose portion 15 and in the rib 23 ofthe bolt, respectively, a spring 35 coiled about said shaft having one end bearing upon said gate member and yieldingly pressing its end 31 into engagement with the plate 10, said end being bent into offset relation, whereby it engages flatly upon said plate. The gate memer is provided with a substantially semi-circular cut-out portion 36 at its forward edge, which embraces the hub of the roll-back 29. In the normal operative relation of the parts, the outside handle roll-back 29 engages the end 3l of the gate member, and thereby operates to retract the bolt, as shown in dotted lines in Fig. 1.
In order to render operation of the outside handle inetfective, throughmanipulation of the inside handle, there is provided, intermediate the gate member and the inside handle roll-back, a bell-crank lever 37 pivotally mounted upon the plate 10 by means of a rivet stud 38. The long arm of this lever extends at its forward end above the upper end of the gate member, and is provided with a knife-edge camming portion 39 adapted upon depression of the lever to enter beneath the end portion 31 of the gate member to thereby raise it away from the surface of the plate 10 to a point where the outer handle roll-back will move beneath 'said portion, as shown in Fig. 4. A bevel edge portion 40 provided on the portion 31 facilitates engagement of the lever end therewith. The short arm 41 of the lever is connected at its lower end by a helical spring 42 to a lug 43 provided on the hub of the outer handle roll-back, and has the double function of yieldingly maintaining the outslde handle roll-back in its normal position in cont-act with the flange 11, and of tending rotate the lever in clockwise direction, that 1s, to disengage the same from the gate member.
A lug 44 is bent from the lever and engagesthe periphery of the inside handle rollack 27 at a point between the circumferential surface 45 at one side and a cam rise surface 46 at the other side, a notch 47 being provided adjacent said surface 46.
The operation is as follows: As shown in Fig. 1, in which the parts are in their normal operative relation, they latch bolt is retracted rom the inside by the inside handle, the roll-back 27 being rotated in counter-clockwise direction, and bearing directly upon the fiange or rib 24 of the bolt. It is retracted from the outside by the. outside handle, the roll-back 29 being rotated in clockwise direction, and through pressure upon tbe gate member 32, as shown in dotted lines, Fig. 1, retracting the bolt.
In order to render operation of the outside handle ineffective to retract the bolt, the inside handle is moved through a partial rotation in opposite direction to its noi-mal retracting movement, (Fig. 4) bringing the cam portion 46 into engagement with the lug 44 and thereby rotating the lever 37 to bring its forward end beneath the upper end of the gate member, the latter being thus moved out of operative relation with the out side handle roll-back 29, this relation being yieldably maintained, as shown in Fig. 4, through engagement of the lug 44 in tbe notch 47. Upon actuation of the outside handle in this relation, the roll-back 2f) moves beneath the gate member, and such actuation is therefore ineffectual to retract the bolt.
The normal operative relation of tbe outside handle is 'restored upon moving tbe inside handle in retracting direction, tbe initial movement disengaging the lever 37 from the gate member, which moves under the action of its spring into operative relation with the outside handle roll-back, and the continued movement causing retraction of the bolt.
Under all conditions the latch bolt is free to be retracted independently of the handles, that is, by pressure directly applied at its nose, as in slamming the door closed.
I have illustrated and described a preferred and satisfactory embodiment of the invention, but it will be obvious that changes` may be made therein, within the spirit and scope thereof, as defined in the appended clalms.
Having thus described my invention, what I claim and desire to secure by Letters Patent is 1. In a latch, a latch bolt, retracting means for said bolt including inside and outside manually operable means,'a retracting member interposed between said outside retracting means-and the bolt and connected to said bolt, and means associated with said inside retracting means adapted upon manipulation of the latter in a non-bolt-retracting direction to remove said retracting member from operative relation with said outside retracting means.
