Loren mya Weddle, Inglewood, cam. Application December 11, 1936, Serial No.‘ 115,408 (Cl. 292-299) 3 Claims. The present invention relates to new and use ful improvements in latches particularly for cabi net doors, gates, etc., and has for its primary object to provide, in a manner as hereinafter set 5 forth, a device of this character which, while positively securing a door, gate‘ or the like in closed position, is adapted to be released with a minimum of effort. I v . Other objects of the invention are to provide 10 a latch of the aforementioned character which will be comparatively simple in construction, strong, durable, highly efficient and reliable in use, compact, and which may be manufactured and installed at low cost. All of the foregoing and still further objects 2 and advantages of the invention will become apparent from a study of the following speci? cation, taken in connection with the accompany ing drawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein: Figure 1 is a view in side elevation of a latch constructed in accordance with the present in vention, showing same installed in a cabinet. Figure 2 is a view in top plan thereof. 25 Figure 3 is a view principally in vertical longi tudinal section, taken substantially on the line 3-3 of Fig. 2. ' Figure 4 is a detail view in perspective of the 30 casing. Figure 5 is a detail view in perspective of the pivotally mounted ring yoke. Figure 6 is a detail view in perspective of the stop. 35 Figure '7 is a detail view in perspective of the member which connects the ring yoke to the operating rod. Referring now to the drawings in detail, it will be seen that the embodiment of the inven 40 tion which has been illustrated comprises a cas~ ing which is designated generally by the refer enoe numeral I, said casing being substantially rectangular in plan and including an integral plate 2 having apertures 3 in its upper and lower 45 end portions which accommodate securing ele ments for mounting the casing in position on a cabinet door 4. The casing I may be of any suitable metal and, as shown to advantage in Fig. 3 of the drawings, said casing is mounted on the Ch 0 door 4 at a point above and adjacent one of the shelves 5 of the cabinet 6. The casing I, it will be noted, is open at its top and bottom and. the plate 2 extends above and below said casing. 55 The upper portion of the plate 2 has formed therein» an opening 1 the purpose of whichrwill be presently set forth. ' Extending between the side walls 8 of the casing I, adjacent the plate 2, is a pin 9 on which a yoke I0 is journaled for swinging movement in a vertical plane. Projecting longitudinally from’ the upper portions of the ends of the yoke Ill are lugs vII which are adapted to rest on the end wall I2 of the casing I. Mounted transversely in the lower portion of the yoke I0 is a pin>I3 on which a gravity actuated ring I4 in the form of a metallic tube is loosely mounted. The ring I4 is engageable behind a stop I5 which is adjust ably secured on the shelf 5. Mounted transversely in an upper portion of the yoke I0 is a pin I6 on which an upstanding plate I‘! is journaled. The plate Il has fonned in its upper portion a threaded opening I8 (see Fig. 7) . The door 4 has formed therein an open ing I9 which is aligned with the opening ‘I in the plate 2. The openings ‘I and I9 accommodate a slidable rod 20 having a threaded inner end portion extending through the opening I8 of the plate M. It will thus be seen that the rod 20 is threadedly connected for adjustment to the 25 plate ll. A look nut 2| is provided for securing the rod 20 in adjusted position. The rod 20 is slidably mounted in a face plate 22 on the outer side of the cabinet door 4. Fixed on the outer end of the rod 20 is an operating knob 23. A coil spring 24 encircles the rod 20 and has one end engaged with the face plate 22 end engaged with the connecting yieldingly resisting outward sliding said rod. It will be observed that and its other plate I’! for movement of the openings 35 1 and I9 are of suf?cient diameter to accommo date the coil spring 24. It is thought that the operation of the latch will be readily apparent from a consideration of the foregoing. To release the door 4, it is only necessary to exert sufficient outward pull on the rod 20 to compress the coil spring 24, thus swing ing the yoke I0 upwardly in the’ casing I until the ring I4 will clear the stop I5 for permitting said door to be swung open. When the outward 45 pull on the rod 20 is released said rod is re turned to its former position by the coil spring 24 and the yoke I0 returns to its lower position with the lugs II resting on the end wall I2 of the casing I. When the door 4 is closed the 50 loosely mounted ring I4 engages and rides over the stop I5 and drops by gravity to locking po sition therebehind, as clearly shown in Figs. 1 and 3 of the drawings. When in this position the ring I4 wedges between the stop I5 and the 55 2V 2,107,066 end wall I! of the casing l thereby positively se curingthe door 4 in closed position. When rid ing over the stop I5 as the door is closed, the ring l4 swings upwardly on the pin l3 into the yoke It). It will thus be seen that little or no effort will be required to close and latch the door while su?icient effort to overcome the ten sion of the spring 24 is all that is necessary to release said door. It is believed that the many advantages of a latch constructed in accordance with the present on the other end of the casing, a pin mounted transversely in the yoke adjacent the open end thereof, a gravity actuated ring loosely mounted on the pin and engageable between the stop and said other end of the casing for securing the closure in closed position, and means for actu ating the yoke for lifting the ring out of en gagement with the stop, said means including an upstanding plate journaled in the yoke, a hori zontal rod extending slidably through the closure 10 and the ?rst named plate, said rod being thread invention will be readily understood and although edly connected to the second named plate, an a preferred embodiment of the device is as illus “operating knob on the outer end of the rod, and trated and described, it is to be understood that ‘ a coil spring encircling the rod and engaged changes in the details of construction and in the ~with the second named plate for yieldingly re combination and arrangement of parts may be sisting outward sliding movement of said rod. resorted to which will fall within the scope of the 3.
