DOOR LATCH.

Application filed October 6, 1921. SeriaI No. 505,911.

To all whom it may concern:

Be it known that I, ALoUIN E. KINTNER, a citizen of the United States, residing at Painesville, in the county of Lake and btate 5 of Ohio, have invented certain new and useful Improvements in Door Latches, of which the following is a specification.

This invention relates to a door latch, more particularly to a combined latch and in look capable of application to a door, whereby it maybe held closed and also looked, when desired.

One object of the inventionis to pro vide a latch of simple construction capable .3 of being easily applied to a door.

Another object of the invention is to provide a latch of novel construction capable of application to either a right-hand or lefthand swinging door.

Another object of the invention is to provide an improved combined latch and lock of relatively simple construction and capable of ready application to doors of various types.

vide a reversible door latch and to combine therewith a relatively simple locking member correlated to operate in either position in which the latch is placed.

Afurther object of the invention is to provide an improved combined latch and lock capable of application to a sliding door.

A further object of the invention. is to provide an improved latch so constructed that it may. be applied to a right-hand swinging door, a left-hand swinging door or a sliding door, as desired.

Other objects of the invention will be apparent to those skilled in the art to which my invention relates from the following description taken in connection with the accompanying drawings.

In the drawings, Fig. 1 is a fragmentary view of a door frame and door to which is.

Another object of the invention is to pro side of the door.

Referring to the drawings, 1 indicates a door frame. 2 indicates a'door hinged along its left-hand edge to the frame 1 by suitable hinges 3, only one being shown. 4

indicates a latch pivoted at its inner end on r a pivot pin 5, whereby its outer or free end may be engaged with or disengaged from a keeper, indicated as an entirety at 6. The pivot pin 5 may. be secured or mounted upon the door 2 in any suitable manner, but by preference the pin 5 extends through an opening 7 in the door 2 and, is secured therein by a nut 8 screw-threaded on its inner end. In order that the latch 4 may be adapted for a right-hand or left-hand swinging door, I prefer to form it from a substantially U-shaped member 4 andgto dispose the legs P of the U upon opposite sides of the door 2 and to pivot both ends of the member'on' the pivot pin 5. At a point centrally of the base 4* of the U. the metal is bent outwardly and then back on itself, as shown a1t4, to form a projection P which engages and disengages the keeper 6 in the manner to be hereinafter set forth.

Intermediate their ends, the legs 4* of the U-member are preferably bent laterally or outwardly to form handles by means of which the latch may be elevated at either 7 indicates a sheathing preferably comprising a U-shaped member formed from sheet metal, and adapted to fit the opposite sides of the door 2 and guard it against wear or damage due to the operation of the latch 4. Near their inner ends, the side plates 7*, 7 of the sheathing 7 are formed with alined openingsfi", which serve as suit able, bearingsfonthe pivot pin 5. The end wall ofthe member 7 is preferably cut "away, asshown ati7, to form shoulders 7 whiQlLli-mit: the raising and lowering, of; the latch 4; Whern thesheaithing isprov ded, the latch 4 is made of proper size to fit in the cutaway 7 and engage the shoulders- 7 "The j sheathing may be; secured to the fdoor'2 by suitable screws 8:

(fat'which time the latch 4"may engage anddisen'gage th'e'notch but by swinging the. locking member to the position shown in full ines, the shoulder 14 of the arm 14 will overlie the notch 6 and thereby lock the latch a therein.

.Whfin in this latter position, one of the it will be understood that the locking member 11 will in normal position be disposed as shown, in Fig. 7and when it is desired to lock the latch 4,it willbe swung on the pivot 13 until the shoulder 15 of the arm 15 will overlie the. notch 6*. When so arranged, the arm 11 and extension may be secured together by, a pad-lock 17 in the manner already described in connection with the arm 15.

In Figs. 8, 9, 10 and 11, I have shown a slightly modified form of construction particularly adapted for use for latching and. looking a sliding door. In these views, 1 indicates the door frame and 2 indicates the door slidable longitudinally in guides 2"" of any desired construction. In this form 0 construction all the elements of the combined latch and lock are similar in construction to like elements referred to in con-.

nection with the construction shown in Figs. 1 to 7, inclusive, except, the latch, indicated at 4". As shown in Fig. 8, the extension 4* ofthe latch 4; is formed on its lower edge with'a notch 17, the walls of which are' adapted to. engage and disengage the bottom wall of one of the notches 6, 6", of the keeper. 6 Topermit the latch 4" to automatically engage the keeper as the door 2* slidesto closed position, the free end of the extension? is beveled, as shown at 18. In operation, the.beveled edge 18 rides, on the bottom wall of the notch 6' to elevate thelatclr lf, in order that the notch 17 may engage the keeper- The keeper 6* may be applied to the door frame 1* so that either notch 69?, 6 may be usedfor latchingthe door 25'. The latch Q may be locked in latched. position by the shoulder 14 provided, on'the arm 14* ot a locking member llfi'which is similar in construction and operation to the locking member 11 correlated with the latch shown in Figs. 1 to 7, inclusive,

hand and left-hand swin in doors 0111 Y the form of construction shown in Figs. 8 to 11, inclusive, may be used'on either a righthand or, left-hand swinging door, if desired as well as ona sliding door. When the'latter form of construction is applied, to a swinging door, the latch at will operate similar to the latch 4, since that portion of the extensio'n' i disposed between outer side Illa") lid wall of the notch 17 and thebevel edge 18 is adapted to engage the adjacent flange 9* of the keeper 6 and guide the latch extension 4" into the adjacent notch 6 and thus permit the walls of the notch 17-to engage the bottom wall of the keeper notch, as shown in Fig. 8.

It will be understood that my disclosures and the description herein are purely illustrative and are not intended to be in any sense limiting, as widely differing embodiments and applications of my invention will suggest themselves to those skilled in the art without departing from the spirit and scope thereof.
