5 Claims.

. This invention relates toman impositive `llock or door catch for use on cabinets, cupboards,

closets or the like, and particularly when such.v

, articles are made of sheet metal. vd

vide a device of the class described which is adapted to be operatively mounted on a sheet metal article of the class described without the use of the usual securing means, such as screws,

i bolts, rivets, welding or otherwise.

Another important object of my invention is to make a door catch of simple construction which can be made economically and which will operate silently and efficiently.

Other objects and advantages of my invention will either become apparent from the description thereof written in connection with 'the accompanying drawing, or willl be speciiicaliy referred to hereinafter. l 20 Figure 1 of the drawing is a plan view illustrating, by way of example, the manner of mounting my improved eatchon the bottom rail of a sheet metal cabinet or the like.

Figure 2 is a sectional view taken on line 2-2 4g5 of Figure v1 andlooking in the direction of the arrows.

Figure 3 is a front view of the device shown in Figure l with the right hand door removed.

Figure 4 is a view of the outline of an openy 30 ing pierced in the face of the bottom rail of a cabinet suitable for cooperating with my catch to retain the same in operative position.

Figures 5 to 8 are side and plan views respectively of t'wo hingeably cooperating outside and as inside members comprising the part of my catch which is secured' to the cabinet as distinguished from the door.

Figures 9 and 10 are detail views of the manner of assembling the outside and inside mem- 0 bersr shown in Figures 5 to 8.

Figures 11 and 12 show my improved catch as assembled and prior to mounting or Abeing nally secured to the cabinet or other article on which it is to be used, as shown in Figures l, 2 and 3.

45 Referring now. to the drawing, and particularly- An important 'object of my invention is to proas at 2i and 22, to formshoulders 23 and 2d. The portions of the side pieces remaining between the notches 2| and 22 are bent outwardly to form respectively a lug on the end of the side i 6 and a lug 2t on the end of the side I'i. 5 It will bev noted, for reasons to be hereinafter referred to, that the inside surface 2l of the lugs 25 and 2S are spaced from the' shoulders 23 and 2d a distance approximately equal to the gauge of the metal from which the rail 62, to be hereinafter described, is formed, leaving the lugs 25 and 26 connected, as it were, to the sides i'and il by a neck 28. A lug 29 is struck out of the side i7 and bent inwardly, as shown, for a purpose to be hereinafter described.

Referring now to Figures 7 andr 8, it will be seen that a second U-shaped or inside member i B ismade of a single strip of sheet metal which is bent to form a pair of side pieces 3i and 32 connected at one end to amore or less circular shaped base 33, having an inside curvature similar to that of the rounded end 20 of the lugs i9 above described. A portion of the base 3 3 is swaged or otherwise bumped or bulged outwardly to form a knob 3d projecting in the direction of the longitudinal axis of the member 30 and adapted to cooperate with the base i3 `of the member l5. The free ends of the side pieces 3| and 32 are formed with inwardly curved portions 35 having outwardly extending ends 36 adapted to engageably cooperate with a suitably formed keeper 3l, secured in any suitable way to the doors 38, all as shown. in Figures 1 and 2. The keeper here shown is cylindrical and made to resemble, somewhat, the head of a pointed collar button, although it will be understood thatkeepers of other forms may be used. Clearance notches 39 are formed on opposite edges of the side 32 of the inside member 3@ to facilitate the assembly of the device.V

Referring now-to Figures 9 and 10, it will be `understood that the outside and inside members I5 and 36, above described, may be assembled by disposing the member 30 between the sides of the member i5 and moving the former in the direction of the arrow shown in Figure 9, until the inwardly projecting hinge lugs i9 on the member i5 have passed through the notches 39 on the member 3d, afterwhich the member 30 is moved bodily to the right whereby the side 32 proximate the base 33 is disposed between the hinge lugs i9 and the base i8 of the member i5, whereupon the member 3G is then rotated in the direction illustrated by the arrow in Figure l0 to hingeably connect the same to the memberIS. 'Ihe two members II 'and Il are finally assembled as shown in Figure l2 with the sides ofeach member disposed normal to the the other, by opening the sides I6 and i1, f i enough to permit the lug Il to be disposed between the sides Il and I2 of themember Il. Figure il illustrates how the lug Il will limit the oscillating movement of the member Il between two extreme positions when said manber Il is ilnally hingedly assembled on the lugs I 8 to the member I5, as above described. It will be understood that the purpose of the knob M is to insure that the base of the member Il iits snugly, albeit hingeably, between the base Il and lugs I 9 of the member Il.

Referring now to Figure 4, it will be seen that a generally rectangular hole or opening li is pierced in a rail I2 in which the lock or catch is to be positioned. It will be understood that the lock may be located on any other suitable part of the cabinet or cupboard and that the manner here shown for mounting the same is merely illustrative. The hole 4I comprises notches Il formed `opposite each other in the short sides thereof, whereby abutments u are formed for the purpose of cooperating with the shoulders I3 and 2l of the member Il to secure the lock in` operative position on the cabinet. The width of the. hole Il is approximately equal to the width of the sides i6 and I1 while the length of the hole 4I is somewhat less than the distance between the flared ends of the sides II and i1 whereby the member I5, with the member Il assembled-therein, may be pressed into the hole Il against the resilient pressure offered by the sides I6 and I1 against the abutments 44 until the surfaces 21 of the lugs 25 and 2i come into engagement with the surface of the rails I2, whereupon the sides I6 and I1, being resilient, will spring outwardly and dispose the shoulders 23 and Il beneath the abutments u with the neck 2l disposed in the notches-I3 of the hole Il and prevent the withdrawal of the catch from the rail 42.

Referring now to Figures 1 and 3, it will bev seen that I have illustrated diagrammatically how a pair of impositive locks like those above described may be mounted proximate the center' and on the bottom rail of a cabinet having two doors 30 hinged respectively at points remote from the center of the cabinet by means not shown. A depression 46 is formed in the lower forward edge of the rail to enable one to take hold of the inside of the door and open the same by withdrawing the keeper 31 from between the ends 35 of the member 30 when the same is mounted on the cabinet, as above described.

Other advantages of my improved lock are that the inner member 30 is adapted to move from side vto side, as shown in Figure 1l, and align it' self so as to properly cooperate with the keeper 31 and make it unnecessary to use extreme care in properly mounting the keeper with respect t0 the front edge of the door. Moreover, the width of the member 30 and its outward ends is larger than the keeper member so that the lock is adaptv ed to cooperate therewith if the cabinet becomes twisted slightly or the keeper located at slightly varying distances from the lower edge of the door. 'I'he binding action between the knob u on the member 30 and the base il of the member I5, is preferably made to prevent the former from rattling with respect to the latter and at the same time insure proper movement thereof and that the catch will operate quickly in adjusting itself as occasion requires.

Vside and automatically adjust itself without scraping the finished surface of the member on which it is mounted. y

Various modifications in the configuration,

-eomposition and disposition of the component elements which' in combination constitute my improved impositive lock may occur to those skilled in the art, hence the foregoing description of my invention is intended as an aid in understanding the scope of the appended claims and not to unnecessarily limit the same.
