CURTIS MAXON, OF LOS ANGELES, CALIFORNIA.
PATENT `OF FICE.
i LATCH.
Application mea July 7, 1924. serial. No. 724,622.
To all whom @'15 may cof/wem:
Be it known that I, CURTIS MAxpN, a citlf/.en of the United States, residing at Los Angeles, county of Los Angeles, State of California, have invented new and useful Improvements in Latches, of which the following is da specification.
This invention is a latch for cupboard doors and the like, controlled by a push button movable perpendicularly to the surfacepf the door and actuating operating mechanism which extends through the door. It is `the object of the invention to provide bolt mechanism for a latch of this character, movable across the rear surface of the door for projecting or retracting said bolt transversely to the direction of movement of the operating mechanism, whereby said bolt may engage or disengage a retaining catch mounted on either the door frame or a shelf of the cupboard.
i, It is a further object of the invention to provide extremely simplied operatingv mechanism for shifting the bolt of the latch' transversely to the direction of movement of the operating mechanism ;r and tofautof matically returnthe boltof the latch to engaging positionupon release of said operating mechanism.
It is a still further object of the invention to readily center the operating mechanism and maintain the parts in operative engagement after initial adjustment thereof; and
to also provide for adjusting th'bolt mech-.
anism transversely of the operating means, so as to conveniently adapt the latch to a door having either astraight or rabbeted edge, without necessitating adjustment. of the operating mechanism.' The invention will b e understood from the following description of the. accompanying drawings, in which, y f
Fig. 1 is a horizontal section through the latch mounted. on a cu board door. 3 Fig. 2 is a rontelevatlon ofthe operati ing mechanism of the latch.
Fig.' 3 is .a rear elevation. of the latch mechanism partly broken away. v F Figl is a detail section on the line of ig. 5. isa 'front elevation of the retaining washer of the operating mechanism.
Fig. 6 is a transverse section onthe line G--6 of Fig. 1.
,y Fig. 7 is a' section similar to Fig, 1 showing the latch mechanism adjusted for use` upon a door having a rabbeted edge.
In the drawings, the frame of a cupboard door is shown at 1, with a door 2 adapted to swing to closed position in said frame as shown in Figs. 1 and 7.
A hole 3 for the operating mechanism of 'the back of the door l axially offset central portion' 5' adapted to be received in theend ofhole 3 at the front of the door for centerin said washer. An operating rod 6 is s 'dably mounted in 7l radially corrugated as shown at 9, and the engage said corrugations, in order that the spring may hold the push button and rod against rotation relative to washer 4 after initial adjustment of the parts.
A casing 11 is mounted on .washer 4, so'
as to enclose rod 6, spring 8, and lthe inner end of push button 7, the outer end of s anl `jpus'h button extending outwardly be ond .saidcasingformanual engagement an' being held against displacement by a. shoulder 12 on the end of the casing 4en agmg a cooperating shoulder 13 on thepus button. Casing 11 maybelield in positlon lby screws,
.14 extending -through the same and washer 4' into. the rail ol. door 2.
an axial `bore in the washer, the end of the ends 10 of Vsald spring `arey bent so as to The surfaces of offset 5 andfpush button" i which engage the ends of spring v8 are v The casing for the bolt (ofthe latch is.` l*
I shownat 15, mounted onthe inner surface of the rail'of the door by' anges 16 projectinglaterally from said casing and fixe to the door rail by screws 17 The casing 15 -has an open base, and 'the-length thereof '-disassembling the latch.'
extends transversely of the door rail with said open base overlying hole 3 and extending beyond the same transversely of the vertical door rail. v
A closure plate 18, shown as lU-shaped in cross-section, is mounted in the open base of casing 15, said plate having a recess 19- A boit 2e is. longitudinali-f slidabie-incasing 15, said bolt being preferably square in cross-section with its front end projecting through a similar squared aperture in the end of the casing. The rear end of the bolt forms a shoulder24 inside of the casing, with a in project'in longitudinally therefrom t roughl a suita le aperture in 26, comprises an arm 26 .the rear .end of casing 15. A coil spring 26* encircles pin 25 with its respective ends abutting ,against shoulder 24 and the rear wall of the casing,0 for normally projecting the lfront end'of the bolt from casing 15 and transversely of the vertical rai of door 2. a
The means for retractin the boltlongitiidinally of casing 15 an transversely of.
the 'door rail, against the tension of spring versely from the bolt ins' edf casing 15 -casin Arm 26is adjustable len and extending through one' or the other o slots 20-21.m to hole 3 in'alinement with operating rod6. Arm 26 and rod 6 have` end abutment surfaces 27,. inclined `as shown in Fig. 1, relative to the directions of move- 4' ment 'of both the bolt 23 and said operatwardly 'against the. tension of spring 8, arm 26 will be'shifted laterally .-relative -tosaid ing rod, so that when the rod is-.pusl'ied i11- ope'rating'wd for retracting bolt 23 into 23, as by providing a threa ed 'stud `28 on the end of saidarm adapted .tobe received .in one orithe other of threaded bores 29- arm 26 mounted in one or the other therespaced .longitudinally of said bolt. lhe threaded bores 29' are so positioned that with of, said iarm 'will roject through either slot 20 or 21,. the e on ation of saidslots permitting movement o the arm and bolt for retraction'l or p ro'ection of the latter, with the ends of sai slots and vpartition 22 limiting said movement of the bolt.
When mounting the latch upon a.. door, hole 3may be bored at'an'y desired height and in the usual spaced relation from the rejecting transedge of the door, the pushbutton operating mechanism being mountedv concentricallycasing 15 is shifted transversely of the verti cal door rail relative to hole 3, until arm 26 over said hole as previously described. The
secured to bolt23 at either of the threaded I bores 29 and projecting through one or the other of slots 20-21', is in alinement with operating rod 6.V The casing is iixed in adjusted position by screws 17, said adjustment of the casing alining the forward end-of'. the bolt 23 when in its projected position, with the edge of a door having either a straight edge as shownin Fig. l, or a rabbeted edge as shown in Fig. 7 without changing the position of the push button operating mechanism of the latch, relative to the` edge of the door.
A retaining catch adapted to be engaged yby the bolt of the latch when said bolt is inprojectedv position, and adapted to be disthe door having either a straight or rabbeted edge, I
without changing the position of the push button operating mechanism of the latch.
Vwhich extends th'ough saididoor. c
It will be apparent thatvarious changes may be made in the construction, combination, and arrangement of parts as thus deof the invention.
I claim:
