LATGHING AEEANGEMENT EOE noons on` WINDOWS.

To .all whom t mag/concerns 1 Y I- Be it known that I, PETER FRANTZ,aoitizen-of the United States, andfresident .of Sterling, Whiteside County, Illinois, -have invented a certain newand useful Imp-rovement' in Latching Arrangements for'Doors o'rxWindows, lof specication. n l f This f invention .relates Vto .latching devices for' doors and windows, .and .-inore 'particulafrly to. those involving the use ofY bolts" for p securing the. upper or lower end ofthe' door,

or of the swinging window, or bothr thev top` and-bottom, inthe well known manner.

Generally stated,I the'object of the inv-en-` l tion is to provide novel; and improvedmeans for moving the boltfrom the latching -position thereof, when. it is desired to open' the door or window, Yand whereby the handle `by which'the door or window vis. opened and closed," may .be turned orV oscillatedf to frey lease the bolt fromiits lockingengagement with the doorway, or whereby azplurality' of bolts may be thuscontrolled, depending rupon thecharacter ofthe door or window, or similar structure,i'1pon.which` the invention is employed. It isalso an object to provide certain details and features of construction andco-mbinations'tending/to inf'zreaser the general efficiency and desirabilityl of a latching lbolt arrangement of this particular character;

To these and 'other usefulends, the invention consists inthe matters `hereinafterl set forth and claimed, and as .shown in the accompanying drawings; in which,-

Fig. 1A is an inside 'elevationY of a'latching bolt .arrangement applied to a swinging. door, involving the use' of'a bolt at'the top. and vanother one for thebo-tt'om of the door, involving the principle of the invention.

Fig. 2 is an enlarged vertical section on line 2-2Y in 4Fig.` 1.;

` .Fig. 3isan enlarged horizontal'section on line *3-3 in Fig. 1. .'fFig; 41 i's an lenlarged on line 1 4l in Fig. 1.

Fig.'^5f is avertical section on'line15Y-5 "Fig- 6 is adetail view ofa portion of the handlemechanism for controlling the latching bolts. .l f Y' Fig. 7 is a similar Yview'of. anotherY por. tionof said handle'mechanism. -5As thus illustrated, the inventionfcomhorizontal section which thexfollowing is. av

i prises a vdoor 1 mounted to swing outward, yinany suitable or desiredmanner. Latchingbolts having casings 2 are mounted at'y top and bottom of said'door on the inner surface thereof, andeach casing `is provided with afsliding Vbolt 3, these bolts having their outer. ends rounded-or beveled at 4 to enable vthem to automatically slide over' thestrike piecev 5 or other" means for engage'ment with lfthe bolt, thereby to latch the door in closed position. Each bolt has a reduced portion Y6 forminga stem which slides in the guide formedlby `the end piece? of theecasing2 of the latching bolt device, and a'coil spring 8 is yapplied tofsaid stein 6, between the vshoulderl 9 and theV guide 7, whereby the .spring of each ylatching bolt device tends to keep the bolt in locking position. Chains 10are`connected t0 the outer ends of the stems 6 of the latching bolts, and yby pulling on' these chains,` the springs 8 of the two bolts will" be compressed, and the outer engaging end-portions ofthe bolts will'he disengaged from theirstrike pieces; whichlatter arepsecured to "the doorway in fixedY position Vin any suitable orl desired manner. The handle chains`10, wherebyI to ncontrol the .two 'latching bolts, comprises an inside grip or loopshaped handle'. 11 which is fixed on a bifurcated member 12,y which latter extends through the opening 13 `formedin the door. This 'member112'tis heldin position for rotation,I but against endwise .'di'splacement, the bracketMwhich-isy secured to theidoory ing 17 will exert a pull on each chain, thus releasing the latching bolts from their locking engagement with thestrike pieces on the doo-iframe, so that' thel door can be opened by means ofV said handle. V Outside the door a similarh'andle 18 Vis providved,iwhich is fixed on the outer end of lthe Vmember '19, this member 'being bifurcated, as shown, to

.. receive the said member 12 in interlocking rotation of one handle engagement, whereby y The member 19 is held will turn the other.

, againstzendwisedisplacement by the bracket plate 20,"the latter having an opening pro'- lviding la swivelsbearing 21 in which the member `19 is freetoturn.. This bracketv 20 Y upon the circumstances.

is secured to the door by screws 22, as shown, and thus the two handles are connected aX- ially, so that .turning of one handle will turn the other, but by removing the screws 15 and 22, the handles can be disconnected from each other and from the door. y

Inside the door, the portion 23 of handle 11 is formed with diametrically opposite notches 24 to engage a locking bolt 25 in the casing 26, said bolt being controlled by the handle 27, in the usual or any suitable manner. By having the two notches 24, t-he arrangement can be used either on a right or left door, and the bolt 25 will be'arranged to engage one notch or the other, depending Thus, when the latching bolts 4 are in locking engagement with their respective strike pieces on the doorway, the door is held in closed position, and when the locking bolt- 25 is in engagement with one of the notches 24, the outside handle 18can be turned to unlatch and open the door.l The person inside of the building can do this, of course, by operating the handle 27 to release the bolt 25 from its lock'7 ing engagement with the portion 28, thereby to permit rotation of the handle 1 1, and the consequent withdrawal of the bolts 4 from latching engagement with their strike pieces.

ln addition, the bracket 20 may have a lower portion 28 provided with an opening 29, and the handle 18 may have an opening 8O adapted to register with the opening 29, so that a padlock 31, of any suitable charac-V r ter, may be applied to these two openings to hold the handle18 against rotation. Vith this arrangement, of course, the doormay be locked from the outside, and may be unlocked from the outside thereof, by means of said padlock. When the door' is closed from the out-side, the ,locking bolt 25 can be withdrawn and held in its casing 26, so that it Will not spring into the notch 24 when the handle 18 is released andatter the door is closed. This leaves the door in condition to be opened, from; the outside, when the padlock 31 is unlocked and taken oit, for then by turning the handle 18 the two bolts 4 will be withdrawn from locking engagement with the strike pieces 5, which arefixed on the doorway at the top and bottom thereof.

rll`hus the rotation of the handle 11, or of theV handle 18, will serve to exert a pull on both chains 10, so that both latching bolts 4 will be disengaged from latching engagement with their strike pieces 5, and thus either handle 11 or 18 is adapted not only to be rotated to unlatch the door, but is also adapted for use as a. grip in opening and closing the door.

After the handle mechanism is unlocked, either handle is then simply rotated to unlatch the door, and "without releasing the vhand 'from either handle, the door'is then opened in the desired manner. Also, when the door is closed, by means of either handle 11 or 18, the latching bolts 4 are automatically pushed into their casings 2 by engagement of their rounded or beveled portions 4 with their strike pieces 5, and thenv the bolts spring into position behind these strike pieces, in the manner shown. Consequently, of course, the springs 8 of the two latching bolt devices employed in this way at the top and bottom of the door serve to hold the handle mechanism in normal position, for rotation of either handle is yieldingly opposed by the springs of the latching bolt devices, when the handle mechanism is not held against rotation by the ordinary latch bolt 25, or by the ordinary padlock 31, as previously explained. The entire latching bolt and handle mechanism by which the bolts are controlledis easily and inexpensively applied to the door, and the construction of the handle mechanism andlatching bolts is such that they are adapted to be inexpensively constructed from metal, mostly sheet metal, thus reducing the cost of production. i

The screws 15 and 25 are covered by the handles 11 and 18 and cannot be taken out while the handles are locked in this position.

lVithout disclaiming anything, and without prejudice to any novelty disclosed, what I claim as my invention is: Y
