T0 all-whomz'tmay concern: 1

Be it known that L'Loor's H. GoRoWrrz, a subject of Russia, and a resident of the city of, NewYork, borough of Manhattan, in the-county of New York and State of New York, have invented .a new and Improved Fastener for Doors and thelike, of which scription. V V

This invention relates to improvements in Securing devices and more particularly to looks for doors, dormer windows, and other hinged closures, an object of the invention being to i provide: an! improved :iastener which: secures the door in closed position or r in partially open'po'sition and which effectually prevents entrance when the :tastener is in either of said positions.

A further objectflis :to provide-'andimproved constructionw and-arrangement of fastener which takes. the place of and dispenses with the necessity for the ordinary chain incominon use and which, when the fastener is released from its door closing position, Wlll automatically assume a positionifor locking the door in partially open which it is intended.

' inventionjc'onsists in-ce'rtain novel features hereinafter described and pointed out intlie position, so that ifany attempt is madeto force, the door from the outside after it is unlocked, such an attempt will result infailure as the fastener will automatically position itself to secure the door in a partially or limited open position.

it further object is to provide a fastener which can be readily positioned on any door, I dormer window, or other lunged closure,

which Will be neat. andattractive in appearance, which can be easily operated by a child. as well as an adult, which will be strong and durable in" use, and which will most efiiciently performthei functions for With these and other objects in view the of constructiomand combination and RI? rangements of parts as wlll' be more fully claims; f V v In the accompanyingdrawings-- I Figure 1 s a vlew in front elevation illustrating my improved fastenerin position to secure the door when the latter 'is closed:

proved'fastener in connectionwith a door,

it is obvious that it might be used in' con nection with a dormer "window or any other hinged closure. s

"1 represents the} door and 2 the" door frame or j amb,-the latter provided with-the ordinary flange'or bead?) at its outer por tion, against which the door 1' closes so as to prevent the insertion of a tool or "other devicetomanipulate the fastener.

4 represents a plate which is secured to the door 1 means of screws 5101* other securing dev1ces,and at one endprojects be-,

yond the freefedge ofthe door-and isbent outwardly and formedf with "a dove-tailed recess 6,.whereby azpairiof opposed'angular lugs 7 are formed on the end of the plate and:,pos1t1o'ned .at-right angles to the plate forapurpose which will hereinafter appear.

A bracket'8 is "secured, to the frame'or jamb2 by means of screws 9 or other securingfdev ces, and is located in substantial alignment with'the .plate'et." This bracket a locking lever 11 between them, and a rivet 8 is madeyvith a pair of outwardly projecting, perforated lugs. 10 receiving one end of 12 -is; projected through the "lever. and 1 through the perforated. lugs --to provide. a

pivotal'fconnection for the lever with, the bracket.- A j' r The end of this lever adjacent the bracket 8 is formed with a bevelledfor inclined projection, 13, against which the'free. endof a spring 14 engages. 'l his'spring 14 is secured to the-bracket; 8 meansof a rivet/:15 or f other securing device, and by reason of, its engagement with. the leven-ll tends to swing the lever to a position to lock thei d'oor in p t a it e a d also tends to f hold the leve'rineither or both of its other positions, as will be hereina'fter pointed out. This lever ll'isof a wid th just slightly less than the distance betweenithe adjacent T and from a point slight acts'fas a stop or. abutment against which tlfe plate 4 engages to limit the opening so? on the; plate l," V ylre noved from the rivet 121' said lever is made-j wi-th integral 'g-laterally projecting flanges'16,which arei v movable in. the 'dove-tailed reces's 6 of sa'id plate 4', andia crosshead or [integral pin. 17 fisjforme d onthe free endof the lever llland;

engagement of the plate 4 with the lever 11, it will be noted that the angular lugs 7 prevent said lever from pivotal movement after the door begins to open, as the flanges 16 will engage the lugs if any attemptat pivotal movement is made.

A honsing 18'is formed upon or fixed'to the plate 4 adjacent one end and in said housing a latch bolt 19 is mounted to move longitudinally. A. coiled spring 20 is located in the housing 18 and bears at one end against the'rearend 21 of the housing and at its otherend against a lug 22 formed on the latch bolt 19. I he rear end ofthis latch bolt. projects through an opening 23 in the housing and has a pin 24 fixed thereto, and this pin 24 not only operates to limit the forward movement of the latch bolt, but serves the purpose of a finger hold to per- Init a withdrawal of the latch bolt.

Theforward end of the latch bolt 19 is bevelled, as shown at 25, so that when the free end of the lever 11, where the crosshead or pin 17 is provided, is pressed against said latch bolt, itwill force the latch-bolt rearwardly until the lever 11 is in looking position when said latch bolt will spring forwardly and secure the lever in such position.

The bolt 19 is provided on its inner face with a lug 26 adapted-to engage a crosspin 27 in the housing 18 to limit the rearward movement of thebolt. A pair of interlocking lugs 28'are formed on plate 4 and behind these lugs 28 the crosshead 17 is held by the latch bolt 19'when the door is closed. These lugs28prevent any'possibility of longitudinal movement of the lever if any attempt is made to jimmy the door as any pressure ofa jimmy between thedoor and the frame would tend to draw the lever longitudinally, which action would be prevented by the lugs 28. v

The operation is as follows: Assuming the parts to be in the position shown inFigures 1 and 2', with the latch bolt 19 engaging over the free end of the lever 11, the door will be securely locked in its closed position. When the latch bolt l9 iswithdrawn to release the free' endof the lever '11, said lever will swing outwardly to the position shown in Figure 3, the spring ll'serving to force the lever to this position.

If a person outside of the door attempts to force the door open, this operation will be limited by the length of the lever 11 as the lever will beaccommodated in the recess "(3 of plate e and the projecting end of the plate 4 will engage thecrosshead or pin 17 to limit the opening movement of the door.

By reason of the bevelled inner end 13 of the lever 11, the spring 14: will normally swing said lever to aposition to lock the door when partially open, so" that it is not 14 until it is again desired for use as a locking means. This complete swinging of the lever to the left is permitted because the flanges 16 terminate short of the pivoted connection 12 and provide ample space between the inner ends of said flanges and the .door jamb or "frame to allow'the lever to swing free of the lugs 7 of plate 4, but this space is only suflicient for this swinging movement when the door is completely closed, so that it is utterly impossible to release the lever from its locking position except when the dooris completely closed.

To lock the door in closed position, it is simply necessary to swing the lever 11 against the plate 1, forcing the latch'bolt 19' rearwardly until the lever is in locking posit-ion when said bolt will swing forwardly and effectually lock the door.

'While I have illustrated what I believe to be a preferred embodiment'of my invention it is obvious that various slight changes might be made in the general form andarrangement of the parts described without departing from the invention, and hence I do not limit myself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claims.
