Application fled April 8,
This invention relates to latches designed primarily for use in connection with the doors of closed automobile bodies, and especially to latches of the type'comprisrng a latch bolt, outside operating means 1ncluding a handle at the outer side of the door for retracting the bolt, separate inside operating means includin a handle at the inner side of the door or retractin the bolt, and means, operable by manipufation of the inside operating means, for preventing retraction of the bolt by the outside opcrating means.
general object to provide a latch of this type of simple, inexpensive, and compact construction which can be easily assembled and in which the proper operation of the severalparts is insured.
The more partlcular objects of the invention, together with means whereb the latter may be carried into effect, W] 1 best be understood from the following description of a preferred embodiment thereof illustrated in the accompanying drawings, in which:
Fig 1 is a plan view of the latch. Fig. 2 is an elevation looking from the outer side of the door and with the cover plate removed, the s indle of the outside operating mechanism eing shown in section. Figs. 3 and 4 are sections taken on the lines 3-'-3 and 4-4, respectively, Fig. 2..
- The latch casing comprises two spaced parallel plates including a base plate 10 and acover plate 11 having hooked lugs 12 engaging slots 13 in the plate 10, whereby said plates are held in assembled relation. The base plate 10 is formed with guides 14. for a sliding latch bolt 15 having longitudinally spaced projections 5 and 6 roviding bearing surfaces which cooperate w1th the outside and inside operating mechanisms, respectively, the operative end 17 of thelatch bolt projecting through an opening in an angular end portion 18 of the base plate 10. The end 17 of the latch bolt is normally PIOjBCtQdlIllZO operative position by a coil spring 21 one The invention has for-its 'or other non-circular cross section an engages a correspondingly shaped opening in 192a. Serial n. 100,612. I
bolt normall projecting from said free edge.
The outsi e operating means comprises a handle 24 located at the outside of the door, said handle being mounted on a spindle 25 which extends through the door and is opcratively engaged with a roll-back 26 which cooperates with the bearing surface at the end of the projection 5 on the latch bolt.
The roll-back. 26 is formed with a hub por- 0 tion 27 journalled at its ends in the plates 10 and 11 and is of a thickness substantially corresponding to the spacing of said plates so as to be engaged by the latter at opposite sides. The spmdle 25 is preferably of uare with an enlarged non-circular portion 7 lo- I cated between said plates and onwhich is mounted an. operating member 32 having a' projectlon 33 which constitutes a roll-back cooperating with the beari'n' surface on the projection 6 of the latch bo t. The spindle 29 is journalled in an escutcheon plate 34 i which may be secured b bolts or-screws 35 to clinch nuts 36 carried y the base plate 10. The mechanism for preventing retraction of the latch bolt by the outside operating means comprises a dog 37 pivoted at one end, as at 38, to the base plate and having its free end extended into roximity to the out-' side roll-back 26. The dbg 37 is of less thickness than said roll-back and its free end is normally disposed o posite or in the path of movement of a note 39 in the latter so as not to interfere with the retraction'of the 190 latch bolt by the outside operating mechanism. The free end of the dog is engaged by a. leaf 5 ring 40 carried by a pin 41 projecting rom the base plate 10, said spring tending to depress the free end of the do out of the path of movement of the note 39 and into a position to restrain the rollback 26 against operation. In this connection it will be seen that the do ging means operates to restrain the roll-bac of the out- 110 Y side operating mechanism while leaving the latch bolt itself tree, so that the door may.
gagement of a projection 42-formedthereon' intermediate its ends with the periphery of a cam portion 43 of the operating. member 32. Said eriphery is, formed with'a notch 44 adapted, when said operating member is turned into one angular position, to receivethe projection 42 and permit the spring 40 to depress the free end of the dog 37 out of the path of movement of the notch 39 and into operative position.
7 Since the end of the dog '3l cooperates with the notch39 in'the outside roll-back 26, said dog is of less thickness-than said roll-back, and the operating member 32'may also be made of a thickness corres onding substantially to that of the dog.. 1% order therefore to hold said member against move ment longitudinally of the sleeve 30, as well tion, the portion 45 of the cover plate 11 adjacent said. sleeve is preferably dished in.
wardly, as shown in Fig. 4, to engage the outer face of said operating member and the 30 enlarged portion 31 of said sleeve.
The arrangement of the parts above de scribed is such that when the operating member-.32 is turned in a counter-clockwise direction from the neutral positionshown in Fig. Ethe roll-back portion 33 thereof will operate to retract the latch bolt. When said member ,is turned in the opposite or clockwise direction from the position shown,
the projection 42 enters the notch 44, thereby permitting the spring 40 to move the free end'of the dog 37 out of the path of movenent of the notch 39 and into position to engage the outside roll-back 26.
In order to prevent accidental dogging of the latch by impact of the projection 6 upon the 'roll-back'33 when the latch is retracted and suddenly released, means are provided for yieldingly arresting the operating member 32 in its neutral positionwhen moved thereinto-from either direction. Said means as shown comprises a leaf spring 46 secured at one end by a lug or fastener 47 to the base plate ,10, said spring having adjacent its free end ,a centering projection 48 adapted to engage a-recess 49 in the rollback 33 when said operating member is in neutral position. Said spring is also preferably formedintermediate its ends with a second centering projection 50 adapted to engage the notch 49 when the member 32 is turned in a clockwisedirection into dogging position, thereby insuring the entry of the projection 42 into the notch 44 and assisting the spring 40 in yieldingly holding the parts in dogging position against accidental disroll-back 33. v
Having thus described my invention, I 1 claimz.
