LATCH BOLT.

Application filed April 16, 1925.

This invention relates in general to imgu-orements in latch mechanisms,

It is the principal object of the invention to provide a latch construction which can be economically constructed and installed and which will operate in an efficient mannerwhen so installed.

It is a more specific object to provide a latch member which can be stamped from sheet r aterial if desired with the resultant economy of time without in any manner sacrificing the usefulness of the completed construction.

Other and more specific objects will appear from the following description considered in connection with the drawings in which:

Fig. 1 is a horizontal section through a portion of an automobile door showing our invention applied thereto the section being taken substantially on the line 1-1 of F 2.

Fig. 2 is an elevational view thereof.

Fig. 3 is a section similar to Fig. 1 showinp; the latch member in latching position.

Fig. 4; is a perspective view of the operating latch member.

Referring to the details of the drawings there is shown certain portions of an automobile frame member 5 having an opening 6 therein. The frame member 5 may be a portion of an automobile door having the side member 7 constituting the abutment portion thereof at the free or swinging edge of the door. It is to be understood that the frame part 5 may be any suitable supporting frame member to which we may apply the latch mechanism hereinafter described.

The latch member indicated generally at 8 includes the base portion 9 and the latching extension 10 arranged at an angle to the base portion. The angular extension preferably has a slightly reduced width relatively to the base portion 9 of the latch in order to form the shouldered portions 11 thereon which operate .to space the latch member with respect to the frame member 5. The angular extension 10 of the latch member has an inner end or base portion 10 of substantially the same proportions as the opening 6 in the frame. The extension 10 is arranged to be passed loosely through the opening 6 in the frame 7 and Serial No. 23,814.

is limited from outward movement therein by the shoulders 11 and from rearward movement by reason of the angular arrangement of said extension.

The control for the latch comprises a spring member 12 which may be mounted between the base portion 9 of the latch and the frame part 5 and secured in position with. respect to one of these members. The operator therefor includes the transverse operating shaft 1 L connected to the handle member (not shown) in the usual mannei; the shaft 14- having rigidly mounted thereon the outwardly extending arm 15 arranged to slidably engage against the face of the latch member so as to move the parts to un latched position as shown for example in Fig. 1. The shaft 14 and arm 15 are held in inoperative position or in position to permit the latch member 8 to function by any desired spring arrangement that shown comprising the engaging spring 16 supported by the frame as at 17 and engaging against the free end of arm 15 to move the same to the dotted line position shown in Fig. 2. The

springs

12 and 16 operate in conjunction to cause the latch mechanism to function automatically but permit manual control thereof for unlocking the same.

It will be seen that according to the above described construction the latch member 8 is formed as an angular plate which may be quickly and easily stamped from a plate of sheet metal. The assembling of the latch is likewise facilitated since before the operating arm 15 is installed in position the latching extension 10 can be passed through the opening 6 so as to bring the shoulders 11 against the edge of said open ing. The operating arm is then mounted in position shown for example in Fig. 3 and the latch is ready for use. It is prevented from sliding outwardly through the opening by means of the shoulders 11. and from sliding back into the frame member by reason of the angular arrangement of the extension 10. The latch member so constructed is readily displaced for automatic action thereof as when the door is merely pushed shut. The tension of. the spring 152 is easily overcome by rotation of tie operating shaft 14- and the consequent sliding of the free end of the arm 15 along the face of the base portion of the latch. lVhen the controlling handle is released the

springs

12 and 16 return the handle and latch to latching position as shown in Fig. 3.

While we have .shown and described herein a certain specific construction it is to be understood that this is merely illustrative and that the spirit and scope of our invention is set forth in the appended claims.

We claim as our invention:

1. In combination with a frame parthaving an opening therethrough, a latch member comprising a supporting base and a locking extension, said extension passing freely through said opening and adapted to pivot on said frame part adjacent said opening, and means movably engaging said base for controlling said latch member.

2. In combination with a housing having an opening there-through, a latch member comprising a base and a locking extension, said extension passing freely through said opening and adapted to pivot on said housing adjacent said opening, a limiting shoul der formed on said base normally engaging said housing adjacent said opening to prevent the same from passing through said opening, and means for controlling said latch member.

8. In combination with a frame parta latch member comprising a supporting base and an angular locking extension, said latch member engaging and being pivotally sup ported by said frame part adjacent the junction of said base and said angular extension, and means to control said latch member.

at. In combination with a frame part having an opening therein, a latch member rockably supported in said opening and compris ing a plate having a base portion and an angular extension, the. free end of said GK- tension being movable toward or away from said frame part when said latch member is rocked and constituting the latching portion of said latch member.

5. In combination with a frame part, a latch member comprising a supporting base portion positioned within said frame. part and an angular'extension positioned without said frame part, said latch member being loosely. supported adjacent the base of said angular extensioi'ifor pivotal movement with respect to said frame part, and man ually controlled means operating upon said base portion to control the movements of said latch member.

6. In combination, a frame member pro vided with an opening therein, a relatively flat latch member positioned on said frame member and having a portion thereof projecting through said opening and supported thereby, the base of said projecting portion being of substantially the same proportions as said opening to permit the latch member to rock in said opening but preventing any material bodily movement thereof in said opening.

7. In combination with a frame part, a latch member rockably supported thereby said latch member being formed from a single piece of sheet material and including a base portion and an integral extension angularly arranged with respect to said base portion, a stop element formed on said base portion, said stop element and the angular arrangement of said extension normally retaining said latch member on said frame part, and means to control the movements of said latch member.

8. In combination with a frame part pro vided with anopening, a latch member rock-- ably supported by said frame part and coin prising a body part and an angularly ar ranged locking extension integral therewith and adapted to extend through said openthe angulararrangement of said extension forming a shoulder normally engaged with said frame part adjacent said opening for preventing said latch member from moving bodily into said frame part, and means carried by said latch member for preventing said latch member from moving bodily outwardly through said opening.

9. In combination with a frame part having a slot therein and an operating member associated therewith, a latch member comprising an element projecting out through the slot in said frame part and a base part lying within said frame, said base part being mounted in position to be enraged by said operating member, said latch member being rockably supportedby said frame part for rocking movement ins'aid slot and occupy ing substantially the entire slot at alltimes.

10. In combination with a frame part, a supporting plate carried thereby and includ ing two angularly arranged surfaces, a latch bolt supported by said plate and including a part adapted to lie flat against one of said surfaces when in non-latching position and to be'moved outwardly therefrom into latching position.

11. In a latch mechanism, mounting plate having a narrow slot therethrough, a

bolt loosely passing through said slot and supported therein for pivotal movement about an axis extending lengthwise of said slot, said slot being relatively narrow compared with the length of the projecting face of said latch permitting said bolt to pivot in said slot from or toward said plate into latching or unlatching position respectively.
