57 52 60 58 5 H: I i 40 I gfi 4 I! is 1m :1 65 J 56 E 61 r 6 5 55 5627i B archers I ing. When so positioned, the forward end of the its forward edge outwardly flared as at 26. The

strike is preferably made of a strip of metal having an intermediate portion bent to provide a large V-shaped head 27 and a shank portion 23 j extending from outwardly turned ears 29 adapted to be secured to the inner facing .of the door as by screws 30. The outwardly flared ends of the jaws guide the head 2! and when the head is 'fully inserted between the-jaws, the latter grip the shank 28 in back of the head 21.

The jaws 23 are mounted for pivotal movement during the passage of the strike in and out of locking position, and one of the principal features of the invention resides in the simple manner in which the jaws are so supported. .To-this end, the side walls 16 of the box-like housing are provided with integral lugs 32 at their front edges, bent toward each other. sothat they are positioned in end-to-end but spaced relation (see Figs. 4 and 5). The lugs 32 thus provide opposite edges or marginal portions and the jaws 23 are shaped to fitover such edges and to be retained in abuttingrelation therewith by spring means I mounted within the box-like housing. .In the preferred form, the jaws are bent on transverse lines. intermediate their ends to provide grooves 33 in which the edges of the lugs 32 are located.

To hold the jaws against shifting movement relative to the'edges of the lugs 32, the grooved-portion of each jaw is centrally apertured as at 34' to fit over tongues 35 extending from the edges of the lugs 32 into the intervening space,

With the foregoing construction, the jaws are assembled into the box-like housing by inserting them in the space between the tongues 35 and then moving them laterally to insert the tongues into the apertures 34 and to position the grooves 33 over the edges of the lugs 32. To' hold the jaws in such position, as mentioned above, a spring is mounted withinthe housing tending to separate the jaws. In its preferred form the spring, indicated at 40, i a compression spring of barrel-like form and is mounted between and bears against the inner ends of the jaws. To hold the spring in position and prevent it from slipping off the jaws, each jaw is provided with an indentation or boss 4| over which'the end of the" spring "fits. The spring 40 thus presses the inner ends of the jaws flatwise again stops formed by theside walls l6 and holds thejaws in position on theedges of thelugs 32. The sprin 40 also serves to resist separating movement of the jaws 'by the strike.

' In operating the device, when the door is being closed, the head 21 of the strike engages the outwardly flared ends 26 of the jaws and, because of their slant, the strike forces the jaws apart,

thereby compressing the spring 40. The maximum separation of thejaws occurs when the enlarged portion of the head 2'! is entering between the jaws, as illustrated in Fig. '3. After the enlarged portion'of the head 21 passes in between the Ueshaped portions 24 ofthe jaws, the

jaws are slightly spaced to permit easy entrance of the strike, and the spring is under an initial tension. 7 g

Should the strike be slightly misalined with the jaws, the head 21 of the strike will cause one slightly misalined strike as they will on a strike accurately centered with respect to the jaws.

The assembly of the various parts of the catch is such that very little labor is required. The two jaws are first inserted in the space between the tongues 35 and are then moved laterally so that the tongues 35 are inserted into. the apertures 34 of the jaws and the grooves 33 of the jaws rest against the edges of lugs 32 on the front wall of the housing. The bottom of the housing is open so that the spring may then be inserted' therein and positioned between the jaws with its end seated over the bosses 4 I. The spring 40, by its spreading action on the jaWs, holds them in pivotal engagement with the-edges of the lugs 32 and on the tongues 35. The spring thus has the double function of retaining the jaws in place in the housing, as well as to resist separatingmovement of the front portions of the jaws by the strike. r

In the modified form of catch shown in Figs.

6, 7, and 8, the shape of the jaws and the manner of supporting them in the base structure is the sameas in the case of the preferred form.

Thebase s tructure is formed to be mounted within the wall 50 and to be supported by and attached to' the front edge flange 5|. The base structure is preferably made of one piece of metal and comprises a base piece or flange 53 adapted to be mounted on the front face of the edge flange 5| of the wall. The base piece 53 is provided with a central aperture 54. to permit a strike to extend therethrough. To secure the catch to the wall the base piece may alsobe provided with a pair of holes 55 through which screws may extend for threading into apertures 56 formed in the wall flange 5|. 7 4 1 1 Extending inwardly from the'base piec 53 is an extension 51 having formed atits inner end a box-like structure 58th support the strike-receiving jaws. In the'present instance such boxlike structure comprises side wal1s:60 and a rear wallell. Thesideflwalls tii, asin the catchof the-preferred form of :construction, areprovided with lugs 32 each having a tongue-33 to support the jawsin the sameqmanner as inthe preferred formb Since the box-like portion 58 in .thisform net structure, theiside walls 60 :are provided with lugs 62 bent inwardly overthejaws 23 to prevent them from being dislodged by accident and servingto guide the jaws and hold them against turning-Imovement on axes parallel to the springllll.

To permit the catch to be inserted into the interior of the wall 50, "is provided with an aperture 63 of suilicient size to permit me box-like structure 58 to-pass therethrough w l Ihe strike, indicated at 64, utilized with this form-of catch is preferably of rounded form rather A than beingbent from a strip, and is pro- "is' not mounted against aflat face of the eabihaving a box-like portionopen at its frontface, said box-like portion being provided with lugs vided with a stud 65 secured inthe door 52 as by threading it into an aperture therein. The modified form of catch shown in Figs. 9, 10, and 11 is adapted to be mounted in'a cabinet 'insucha manner that thestrike andjaws move laterally relative to each other. Thusthe catch may be mounted on theinside of a'dcor in while the strike is mounted on the adjacent frame II. In this form offcatch, the base structure is substantially thesame as the base structureshown inrthepreferred form, but the attachihgears, here indicated at 12, may, if desired, be reduced in sim. J

-. .LSince the catch is designed for a strike which moves transversely of the-jaws, that is, a strike scriptionthat I have provided a catch, the base structure oi'which maybe varied. so thatithe "catch may be mounted in different wayslon either cabinets made of wood or sheet metal. Also, the

or transversely of. the

jaws.

heretindicated atwfarebent a short distance j along a line extending longitudinally of the jaws to: rovide: a V-shape in cross section, as illustrated in Fig. 10. The V-shape form provides outwardly flared portions so that the strike in entering therebetween will force the jaws apart to permit it to pass between thejaws. When the.

doonof the cabinet is fully closed, the jaw-re- :ceiving portion. of the strike lies between two jaws and in the space between the jaws and the rearsurfaceofthedoor. i

Thestrike in itspreierred form, as illustrated in-Fig l'l, comprises a flange 14 adapted to be secured. to the adjacent edge surface of the wall H. wThe-fiange1tis providedwith an integral portion. extending perpendicularly from the edge of the: wall and rounded into a cylindrical portion,
