PATENT oFF-lcs f 'f'mrcnronfmnenn noone i L'lplicatioxi"inea, Aprilia Thi's'invention relates to .door 'latches and particularly to latches for swinging doors.v The general object of the invention is the te provision ofia latch for aA swinging 'door having means wherebyA the latch may be opened from op'posite'sidesl of the door, and which is soconstructedzthat a relatively powerful bolt may'befused to hold' the: door closed. Y .Ak further.object is to provide a lock of this character with a sliding bolt, rnovideV a pivoted. combined door handle and latch op f v'erat'ingmeans on the exterior of the door, and

` f a slidinglatch operating means. upon the infy p ter'ior ofthe door, and to provide means .15 Vwhereby the latchmay bev-engaged automatically V by a keeper when the doorisjswung n closed without then'ec'essity` of actuating the 'latch to withdraw thebolt jprior tov closing* fMy invention is illustrated-in the' accom- Figurel is a'secti'o'nal. view .through a door a portion 'of Vay door frame( showing my' improvedlatch attached thereto; y Figure2 `is'a'rear face view ofthe/latch;

Referring to these drawings, A designates' the door proper andB designates the iambof thedoorcut out as at bito receive the boltion the-door when the door" is closed. On the inside face of the door there is attached the over the slotted'wall16; Thefmember 19 and thelbolt-proper 18 are joined toeachotherat 20 and then rearwardly and inwardly extend- *1);501 erd'in'a curve asfat21 to forma handle. l` AThe i980. semi No, V$45,046.

portion 19,y it will be seen,..is shorter than the bolt 18 and both the bolt and the portion 19 are formedwith apertures 22 and 28. When theboltis, shifted yforward to its extreme fori ,t

ward position', the extremity ofthe bolt will engage beneath the lip 13.

Mounted by"a"hinge member 24 .upon the` outer faceofthe door A isa handle 25 which beyond the hinge member is. formed torprol videa shank 26y which extends through a slot 27 Y inthe doory and extendsthrough the slots. 22,an'd 23.` 'Attachedfto' the shank 26 is a vspring 28 which in turnis attached to a stud 29 vprojecting from thefspringhousing 14. It will be obviousnow that the spring 28 will act to Yurge thewbolt to, a proected positioin` but .that when the handle 25 isi/grasped and pulled as if to 'open' the /doorylthe shank 26 will move rearward vagainstthe action `of the Y spring 28 and retract the holt v18 and, of course, the portion 19 and handle. 21. Ifon the other hand, the door is locked and the person on. the inside of the door wishes. to open it, he takes hold of thehandle 21 and simply pulls laterally which will act to re# tract the'bolt against the action'of the spring '28'. Itwill bev seen that the bolt isvvery strongly engaged with the housing because it consists of two parts, namely the boltflS` A and the portion 19 which engages on'opposite sides of the wall 15jand furthermore because the extremity of the bolt is'engaged' beneath the lip`13.

' Thefkeeper whereby the bolt is engaged isillustra'ted in Figure landis mounted upon thejamb B. vrThis keeper comprisesthe casing 3() within which yis disposed two pivoted keepersproper and32, each yof these be-v ing pivoted at`33." The extremities of these keepers are' formed with the divergently beveled heads-34;. Le'affs'prings 35 bear against the keepers and force them toward each oth- 'er' and-*against a central. stop y36 to which thisicross bar at its ends itting `in recesses 391form'edffin' the wall of thecasing. As the dooris movingl to its fully closed position the 'bolt 18 bears against thebeveled faces of the keepersfforces these keepers laterally in op posite directions until the bolt has passed'thel a cross bar 3,7 i's attachedfasby the screw 38,4

It is obvious that the handle 25 may have a slot so Uthat when the handle is closed, it can.

pass over a staple so that the handle `mayl be locked by a padlock passed through the staple and thus the door is lockedgfJ-It*willgbe 'seen lthat with this construction, the 4natural movement ofthe handin opening the door by means of the handle 25 will release they latchv and that on the ,insidev of thed'oor, it is only necessary to pull the latch laterally by means of thev handle 21 to` secure the 'same result."VV v This, lock is very simple, can be cheaply A' manufactured and .has been found. to be par-7 ticular'ly:V effectiveffor barn@ doors, garage Y doors and other heavy swinging doors.

It will be noted Ythat practically all offthis latch is 'disposedfonthe inside of the door,

thus keeping it from exposureto the weather and being tampered with. `Ohne'of they! most important advantages'gofmy invention reysides inthe fact thatthe latch is practically Y un aifectedby anyv ordinary. Vshrin kage or'v expension of the door" due tothe dry'A or wet zweather.' Withfother locks known to ine, when the material'ofthe door lshrinksorI thef material ofthe` door casing shrinks,the.lo'ck will lbe causedl to move back too far from the keeper. sothatit prevents the bolt fromgettinga firm hold and keepingthe door closedl and if o'nthe otherhandthe material of the door expands, it will bring vthelock too close Y to` the retainer which will make" it hardy to jamb which gives it :a good solid foundation close unless Vit iszclosed hand,4that is,y by positive retraction of the bolt. j

My latch will be actuated to latch the door ,closed `without`operating the handle, but

merely by pushingthe door towarda closed position@y -K w Ingmy latch, the Vkeeper, is'disposedron the by which to hold the door shut whereas in most latches'known .to me the keeper is mounted-,upon lthe door casing which soonA becomes loose and renders vthe flock` inefL fici-ent. In myy constructionthedoor is held' closed 'by twokeepers 3l and. 32 which lenf gage fthe bolt land thus there is lno chance.V

for the` door` to openfandvthus act tov hold the 'door'closed so-longas theyare fastA to the door.V vWith other flatches knowny to me,

verylittle '.eifort is required tof ,break` the door 'open' asfthe retainers ,orkeepers are short -as are thefbolts and ordinarily there isfonly a single keeperk for ,the bolt-jto engage with. .fThis is particularly vrtrue when the door'h'asl shrunk in `dry weather." l"llhe Vdoor in that case ish'eld by onlyv a vslight engagementl ofthe bolt `with 'the keeper.

viously slight changes might'cbe made in the details of 'construction without departing the appended-claims. y
