(Cl. 292-52) 1 2 This invention is directed to the production of a practical, simple, effective and durable latch of from which, at one edge, a post a is turned at right angles. The post 9 when the latch is closed is adapted to enter the open inner side of the casing or housing described substantially midway be the type known as a cupboard latch which may be used on the doors of kitchen cabinets, cupboards and the like. tween 2. Said thepost front is and narrowed back l atand a distance 2 as shown from in the Among the objects and purposes of the present foot portion 8, as indicated at |53, and then form invention are the production of a latch ofthe ed into a head i I which is wider than the narrow type specified, made of sheet metal parts which or neck portion Iü, and has inwardly converging are economically and expeditiously produced and assembled and with which a secure holding of the 10 inner edges i2 joining with the sides of the neck portion iii, while at its free end it has converging door in closed position is obtained, and with the edges I3 as shown. production of a tighter grip of the latch upon its Within the housing two pivotally mounted jaw keeper when any force is applied to the door in a members are located. Each is made from sheet direction tending to cause its opening, so that the latch is disconnectable only by manual operation 15 metal having a side I4 from which at the free end thereof a jaw I5 is turned at right angles. At of the handle portion thereof provided for disen its opposite end a flange 55a is turned at right gaging the latch from its keeper. Economy in pro angles substantially paraileling the jaw l5 and duction, simplicity in structure and special effec said ñange I5a is return bent at right angies to tiveness in operation are objects of this invention as will appear from an understanding thereof had 20 provide an ear I6 shorter than the side Ill. Tail piece I1 is integral with the flange êäa and eX from the following description, taken in connec tends laterally therefrom at one side edge and is tion with the accompanying drawing, in which, bent at an angle thereto as shown. Fig. 1 is a longitudinal section through the latch The two jaw members are placed together as substantially on the plane of line I--i oi Fig. 2. Fig. 2 is a transverse section substantially on 25 shown in Fig. 4, with the ears I6 on one jaw mem ber located at the inner side of the side i4 of the the plane of line 2-2 of Fig. I looking to the other jaw member.

Fig. 4 is a perspective view of the pivoted latch 30 at the outer sides of the front and back of the housing or casing. A coiled spring i9 is located jaws, and ` around the pin I8 between the ears l@ and has end Fig. 5 is a perspective View of the operating arms 2Q extending in opposite directions, one handle or plate therefor. under the bend between each ilange |50. and tail Like reference characters refer to like parts in piece Il, as in Fig. 3. The force of the spring is the different ligures of the drawing. exerted to normally turn the jaws E5 toward each In the latch construction, a housing or casing other thereby bringing the flanges l5@ together, of sheet metal is provided having what may be said flanges Iiia coming into edge abutting con termed a front side I, a back side 2 parallel there tact, as in Fig. 3 to hold the jaws l5 partially with, a top 3 integrally connected with said iront and back and ends ll, the side of thev housing op 40 separated when the latch jaws are disconnected from the keeper. posite the top 3 being open. From the back 2 a When the door is moved to closed position the flange 5 is turned at right angles to lie against inner adjacent edges of the jaws I5 engage the the outer face of and near the free vertical edge of a door Ii of a cupboard, cabinet or the like, inclined edges E3 of the keeper, being initially which door is normally hinged in the usual man 45 held separated a sufñcient distance that they pass to either side of the nose of the keeper and ride ner for swinging between open and closed position against said edges I3, passing along the parallel and vice versa, in its closed position having an side edges of the head I I of the keeper and thence overlapping riser, as shown in Fig. 2, which bears underneath the inclined edges l2 of the head against the face of the door jamb or casing 'i ad jacent the edges of the opening in the case or 50 (Fig. 1). The inner faces of the jaws I5 bear against said edges I2 of' the keeper head and. the cabinet to be closed by the door Ii. force of the spring is exerted to move said jaws The keeper is permanently secured to the door toward each other with the exertion of a camming jamb or frame 1. It is made from sheet metal, action on the jaws which causes the door to be having a flat foot-piece 8 preferably screw con nected to the outer side of the door casing 1 and 55 held tightly closed. Any force which may act on 2,409,794 3 the door tending 'to open it with the jaws of the latch engaged with keeper head Il is ineffective to move the door, as there is no component of such force which can be resolved in a direction to turn the jaw members away from each other about the pivot pin I8. For manual release of the latch from the keep er an operating handle member is provided, com prising a plate 2| of sheet metal which at one of its edges is extended to provide two spaced apart angles having legs 22 and 23 at right angles to each other, said legs 22 being in substantially the same plane as the plate 2l and from the inner edges of each of which a tongue 24 extends as shown. Initially the tongues 24 are turned to . parallel the legs 23. With such initial shape the angle members 22-23 and the tongues 24 may be passed through channel slots 25 cut in the back 2 of the housing or casing immediately with in the top 3 (Figs. 1 and 3). After this has been done the tongues 24 are bent toward the top 3 of the housing, as shown, thereby locking the op erating member against disengagement, but per mitting a limited pivotal movement in the slots 25. Said angle extensions 22-23 lie over the tail-pieces l1. With the latch engaged with the keeper, as in Fig. 1, an engagement against the inner side and at the outer end of the plate 2| will move the legs 23 into contact with said tail _posite sides thereof, spring means acting on said jaw members to normally move the jaws toward each other, each of said jaw members at the end thereof opposite where the jaws are located hav ing a laterally extended tail-piece, and manually operable means extending through a side of the housing and pivotally mounted'thereon for en gaging said tail-pieces on operation of said means to swing said jaw members to move the jaws away from each other. 2. A latch construction comprising, a housing adapted to be secured to a door and having an opening at a, side adapted to be presented to a door jamb when the door is in engagement there with and receive a keeper connected to said door jamb, said keeper extending into the housing through said opening, two jaw members, each of said jaw members comprising a side, a jaw turned substantially at right angles from one end of said side of each jaw member, a flange turned in the same direction from the other end of said side of each jaw member and an ear bent from said flange parallel t0 the side of its respective jaw member, said jaw members being located one with the side thereof against the inner side of a side of said housing and the other against the inner side of the opposite side of said housing, a pivot pin passing through said sides and ears of the jaw members and carried by opposite sides of the pieces I1 and turn them about the pivot pin I8 30 housing, each of said jaw members having a tail to separate the jaws l5 from each other a dis piece extending outwardly from said ñange por tance sufficient to disengage from the head Il of tion thereof, and spring means mounted on said the keeper. The door is thereupon opened. Upon pivot and having end portions passing under closing the `door the latch jaws automatically . neath Said flanges and tail-pieces and engaging engage with the keeper and hold the door in thereagainst operating to move the jaws of said tightly closed position. jaw members toward each other until adjacent The construction described is made substan edges of said ñanges come into contact stopping tially wholly of sheet metal parts which are read said jaws of the jaw members at their adjacent ily formed in large quantities by use of suitable , dies, the assembly is quick and easy, the jaw edges at a short distance from each other. 3.
