Application inea :rune a, 192s. serial no. 113.227..

y Thisiinvention relates to improvements in. door latches of vthe pivoted bolty type, and

while in its broader aspects the present in vention comprehends a latch which mayhave agwide range of utility, it is particularly concerned with pivoted `bolt latches' for -..swinging closure elements. v u Y An object of the invention is to provide a latchy of this character-.which may be con lo veniently locked against operation, a latch which' is automaticallyA acting. when ythe closure'V is swung' to, ,a latch of simple, practical, construction,y which will be rugged,

durable land eliicient .in use, which may be manufactured with. comparative economy,

`andwhich may be readily applied to a. door orl'other closure element. f

flVith'the abovenoted and otherl objects in. view, the invention consists incertain novel features of construction and combina! tions and arrangements offparts, as will be more fully hereinafter sete forth and pointed outr in lthe claims.- The inventionl may. be more fully understood lfrom the `following description in connection Vwith the accompanying drawings, wherein- Y' y Fig. lis a fragmentary vertical sectional view through a door, with my improved latch attached thereto, the dotted lines indieating Vthe position` of the bolt mechanism when ythe .latch is rocked onits pivot .to dis.- engagev the holtfrom the keeper. t y v .Fig 2 is a view similar to Fig.1.,.but showing the :latch ,locked against pivotal movement. j

Instr-ating a further modified form of latch'.

Figs. 10 and 11l are sectional planv views on the lines-10-1O and 11-11 respectively of Fig. 9.' y i. t

Fig. 12 is a view in` outside elevation of the latch of Fig. y9.

- encircling the arm 118 ofthe vthe bolt from the keeper vfrom the outside c, Fig. 7 is .a lsectional plan view onthe line Referring lirst to the form of doorv latch shown in Figs. 1 to 4, it will be noted that I have uS-ed the reference character 10 to indicate a closure frame, and the reference character' 11 to indicate va closure hingedly mounted at one edge (not shown) and adapt-k VServe `as a pivotal mounting for. one arm 18 of the U-bolt 19., :The latching bolt 21 is mounted torockon the end of the arm4 18,` and isengagejd by the other arm. 20 of the Ubolt 19.

i A keeper21 in the'nature of an L-shapedV brack'etjis secured to thek frame 10, and is engageable in a notch 22 in tlie'lower-edge of the bolt 21a. A coiled torsional spring 23.

against the intermediate portion of said bolt and maintains the pivoted bolt 21 spring pressed .into engagement with the keeper 21a.

It will befnoted that the bolt 21 is formed at its inner endwitha camming face 24 which enga-ges with the keeper 21a Vto ele-- vate the inner end of the holt as the 'door is swung to closed position, and when lthe keeperhas. cleared the notch 22, the boltwill be spring pressed into .its latching position. li`l1`us,thev bolt latches automatically as the door isswung to closed position.

AFor effecting manual disengagement of' of the door, the outer end of the bolt is prol vldedwith a handleV member 25 facilitating the manual rocking of the bolt on its pivot 18. Means are also provided for selectively locking the bolt againstpivotal movement and consequently locking the door to the. frame. This meansiincludes a fork 26 intef gralwith a plate 27 and offset therefrom. Platef27 islpivotedatns lower end to the bottom ofthe outer escutcheon plate 13 as indicated at 28, and when swung yfrom the position .of Fig.. 1 to the positionfofF ig. 2,V the yfork26 straddles vthe' outer-end of-the which register with a U-bolt 19 bears bolt closely adjacent an opening 29 therein. Y

By passing the hasp 30 of a padlock 31 through the opening 29, such hasp will entrage with the itorlt to prevent pivotal movement o'l the holt 2l.

ln Fins. 5 to 8 inclusive, l have illustrated a slight modification of the latch in which di lierent means are utilized for sprint;l pressing the latch into engagement with its lieepcr and tor locking' the latchiney holt against pivotal movement. 'Referring non' to these ligures, the pivoted holt 35 extends through aligned slots in the door ll, and the inner and outer eseuteheon plates 3G, il?. ',llhe holt is pivoted on a screw 25S which ei;- tends across the slot in the door. The inner end ot the holt is notched at 3) toi' engagement with a keeper lll secured to the :traine lith and the holt sprintT pressed into engagement with the lceeilier o v a coiled con-- tractile sprim;` -lt anchored to the, outer end oit the holt, and lo a staple or other suitable anchorage li/Z on the outer tace oli the door. llolt operating handles t3 are provided at both the inner and outer ends ot the holt 35.

The .means` :tor locking` the holt :flg'ainst reciting; movement in this instance includes a channel piece let pivoted at to to the holt on the .inside el the door. .idiacent the channel piece` a pair ot openings it are provided in the loolt. lith the channel piece swung; to the position of Fie'. the shackle t? ot' the padlock Al-S may he conveniently hurle in the lower openinil` Ll@ andnormal operation of the holt may he had. 'It however, the channel piece del is swung; through amiroximatelv 90@ to the position ot Fig'. 5,

and the shackle ot the padlock shifted into the upper opening' 1GH it will he seen that the channel meinten' elieetivelv hloclis pivotal movement ot the holt. Anv attempted roel:- ingr movement thereof to tlisenegago it t'roin the heepen causes the shackle of the padlock to torce the channel member against the inner escnteheon plate.

In Fifi t] to l2 inclusive l have Aillustrated a :turther modilication ot" the invention, in which the holt 5t) is in the nature ot a relativelv wide plate rocking); in aligned slots till in the door 'il and the inner and outer escnteheon plates In this instance `the e ulcheon plates are connected liv a U-liolt ou the intermediate portion ot which overlies the outer tace o'l the outer eseutcheon plate, and the legs of which pass through the inner escutcheon plate ind are retained hv nuts 35. The intermediate portion ot the U-holt passes through an opening; 55 in the latch 5t) and servesI as a pivot therefor.

A coiled cont actile sp1-ingr at 5T to the inside olf the door and engaged at 5S with the inner portion ot the latch 5t), urges the latch into engagement with a keeper 59 secured to the traine l0. Oper- G anchored ating` handles (30 and (3l. are |.n'ovided at the inside and ontside ot the latch. In order to loch the latch against pivotal movement, it is merely neces-'sari' to pass the shackle G2 olf a padloch til througth an opening (lll in the lower edge ol" the outer end olf the latch :30. This padlock engages the escutcheon plate o?) to prevent movement ot the latch about its pivot tiet, ln the l'orm ot the inmiitions previtmsly deserihed. the slots in the esentcheon plates univ serve as au etiective stop to limit the springt pressed movement ot the latehinfg holt when the holt is not engaged with the lieeper. ln the itorm shown in li`ief.-1. t) to 12, cross pins T5 secured to the latch engage the escutcheon plate to limit the spring; pressed movement of the holt when the door opened.

lllhile l have shown certain ot the pre- `l'erred emhodimentiii o'l the invention, it will he evident that numerous changes and alterations` might he made in the general `form and arrangement ot parts described withoutdepartine Afrom the invention. llence l. do not wish to limit` in vsellA to the details set lforth. het shall consider nrvr-rcl'l' at livhertv to malte such maneges and alterations as Yfairly tall within the spirit and scope, oit the appended claims.

l claim: i

l. The iiomhination with a closure 'trame and a swinging closure, ol eseuteheon plates secured to opposite il'aces ol' the closure near the 'tree edge ott 'the latter, said escutcheon plates and closure having' alie-ned slots therein, a holt pivoted intermediate its ends and extending' through the slots, a keeper on the trame, spring means urging' the holt into engagement with the keeper, and means tor selectivel)v locking; the holt against pivotal movement, includingl a `lorked element piroted to one oit the eseutcheon plates and adapted tostraddhi the-holt and he held against movement to inoperative position hy a padlock i-'hacltle passed through the holt. i A
