(Cl. 'I0- 97) 2 Claims and an improved means for locking the bolt.

Another object of this invention is to provide an improved door bolt which is very simple in construction'and which can be constructed in the vsides of a sliding door.

A further object of. this invention is to provide an improved door bolt which embodies a minimum of parts so that it can be made at small cost and will not get out oi' order, the bolt being gravity actuated to locking position and all springs being eliminated.

A further object oi' this invention is to provide a bolt oi this kind which may be .locked or unlocked on one side o! the door without the use of a key, and which may only be locked or unlocked on the other side of the door by use oi a key.

The invention consists of the novel construction, combination and arrangement of parts as will be more speciilcally referred to and illustrated in the accompanying drawings, whereinis shown an embodiment of the invention, but it is to be understood that changes, variations and modincations may be resorted to which fall within the scope oi the invention as claimed.

In the drawings:

Figure B is a detail side elevation of a ni: form oi latch and ooit,

Figure 102s a ionglimdinai section of the device in released position. and

Figure 11 is o. sectional view teken on the line ii-il of Figure Si.

Referring to the drawings. and first to Figures 1 to 8 inclusive, the numerals iii and ii designate generally a pair of sliding doors which are slidingly mounted in the opposite sides of a door opening and which embody a construction similar to that set forth in my cio-pending application Serial Number d5d,324, led August lll, R42.-

Thc door It has countersunir in the opposite sides thereof s. pair o! cup-shaped housings l2 and it; The housing i2 comprises on inner circular wall it, a. cylindrical outwardly extending flange l5 and en annular ange i@ which is adapted to engage against the adjacent face of the door i9. The housing i3 opens outwardly in the opposite direction from the housing i2 and comprises an inner circular wall il, a cylindrical side wall i8 andan annular flange id.

An elongated door bolt 2d is disposed between the two spaced apart inner walls i4 and il of the two housings i2 and i8 and is formed at its outer and lower walls 28 and a front wall il. vThe escutcheon 23 is adapted to be secured in an opening or recess 28 formed in the forward or outer edge of the door I0 by fastening devicesds. The i outer or forward wall 2l of the escutoheon 23 is provided with an elongated opening i@ through which the keeper E0 is adapted to loosely engage. The inner wall 24 is also formed with 'e similar opening to the opening Sli. and the inner end oi' the bolt 20 extends medially between the two housings i2 and i3, as shown in Figure 2. A longitudlnelly arcuate bolt operator or handle 3i is disposed within the open side of the housing i2,

and a similar longitudinally. arcuate handle or bolt operator 82 is disposed within the open side an opening 3l formed in the inner` wall il of the lhousing it. The shaft 33 may be secured on by a pin, 33 to the operator 82 and may bel The guide member 23 includes an inner' vertical walljZd, opposite side walls 25, upper secured to the operator 3| by means of a screw 39 which is threaded into the adjacent end of the shaft 33, as shown in Figure 4.

In order to provide a means whereby the bolt 20 may be releasably locked against rocking movement in an upward direction to a released position, I have provided a bolt locking lug 40 which is mounted on a shaft 4I carried by a bearing boss 42. The boss 42 extends inwardly from the inner wall I4 of the housing I2 and the locking lug 40 is preferably substantially rectangular inside elevation, as shown in Figure 1, so that the lower end of the lug 40 will substantially contact with the1 upper straight edge of the bolt 20. In this position of the locking lug 40, which is shown in dotted lines in Figure 1, the boit 20 is held against upward rocking movement to a released position. The shaft 4I is extended outwardly through the inner wall I4, as

shown in Figure 6, and a releasing button or operator 43 is secured as by a fastening member 44 to the extended end of the shaft 4|.

The locking lug 40 is adapted to be resiliently held in either released or locked position by means of an elongated flat spring 45. The spring 45 is provided at one end thereof with an eye 45 engaging a pin 41 carried by the inner wall I4, and a spring tensioning pin 48 is also secured to the inner Wall I4 in a position spaced from the pin 4l so as to force the spring 45 downwardly into engagement with the lug 45. The free end of the spring 45 is adapted to engage a selected side of the lug 40 depending on the position of the releasing button 43 and yieldably hold the lug 40 against turning movement.

The releasing button 43 is preferably disposed in only one of the housings shown in Figure 2 so that when the locking lug 40 is in locked position the operator 32 cannot be rocked so as to swing the bolt 20 to an upper released position. The bolt 20, when in locked position, is adapted to engage through an opening 58 formed in a keeper generally designated as 50. The keeper 56 comprises an inner plate 5I which is adapted to be secured as by fastening members 52 to the outer edge of the door I I. The plate 5| has extending outwardly therefrom a keeper housing including a forward wall 53, upper and lower walls 54 and 55, and opposite side walls 55 and 51. The walls 55 and 5l and the two walls 54 and 55 are spaced inwardly from the outer marginal edges of the plate 5| so that the fastening members 52 may be secured in position outwardly of the keeper housing or member 50. The keeper 50 includes an elongated slot 58 within which the hook 2| of the bolt 20 is adapted to engage and the opening 30 is of a size sumcient to permit the keeper housing 50 to engage within the escutcheon member 23, as shown in Figure 3. f

Referring now 'to Figures 9, 10i and 11, there is disclosed a slightly modified form of this invention. the changes between the form shown in Figures 9, 10 and 11 being only with respect to the locking lug which is designated 40 in the preferred form of this invention. In other words. the form of inventionshown in Figures 9, l and 11 includes a pair of housings I2a` and |3a similar in every detail to the housings I2 and I3, and also includes a pair of operators for the door -bolt 20a which are similar in every detail to the operators 3| and 32.

The inner wall Ila of the housing I3a is formed.

asomar mounted on a pivot member I. The bolt 20a is releasably held in locked position by means of a pivoted locking lug 52 which is mounted on a shaft 53 journaled through-the inner wall I4a of the housing IIa. A lock releasing button or operator 44a is secured to the shaft 53 and is disposed interiorly of the housing |24. 'I'he lug 52 comprises a polygonal body which is formed withiiat faces 54 and 55 disposed on an obtuse angle relative to each other and also a flat tace 55 disposed on an obtuse angle with respect to a fiat face 55a positioned between the face 55 and the face 55. The lug 52 is formed with a key slot 5l extending inwardly from the edge 5,5 thereof. and preferably the lug 52 is formed with s. cam-shaped member Il extending from the edge 55.

The locking member 52 is yieldably held in either locked or released position by a longitudinally bowed spring l5 which is secured at one end thereof to a pin 1|. A spring tensioning pin 'I2 engages the Spring 15 between the ends thereof, and preferably. the spring 'I5 outwardly from the pin I2 is of substantially inverted V configuration so that the free end 13 thereof will be disposed in a position for' engagementwith either the flat face 54 or lthe flat face 55, depending on the relative position of the locking member 52. A key I4 may be inserted through the keyhole slot 55 when the locking member l2 is in a locking position and the key I4 then turned as-shown in Figure l0 so as to engage in the key opening 51. This turning of the key T4 will swing the locking member upwardly to the position shown in Figure 10 thereby positioning the ilat face 55a in upwardly spaced relation with respect to the upperedge of the locking bolt 20a.

The bolt 25a may then be rocked upwardly by the handle lia or a similar handle disposed in the housing Ila as described with respect to the bolt 25. The bolt 2l and the bolt 20a gravitatingly move downwardly to a. locked position, and the forward ends of these' two bolts are formed with a cam 'l5 so that the bolt 20 will ride over the lower end of the`keeper opening 55 and the hook 2| will then gravitatingly drop downwardly with the bolt 2l on the inner side of the keeper 55 in a locked position, as shown in Figure 3.

This latch and bolt or lock is of simple construction and is soformed that it can be readily countersunk in the opposite sides of a slidingv door as embodied in my co-pending application and the latch may be locked from the inside of the room by means oi the locking member 40 which is operated by turning the operator 43 to a substantially horizontal locking position. Where a key is desired the locking member 52 may be used with the latch device as shown in Figures 9, 10 and 11, the key being extended through the outer housing Ila for engagement with the locking member l2.

What I claim'is:

1. A door latch and lock comprising a pair of outwardly opening annular cup-shapedhousings adapted to be countersunk in opposite sides of a door with the inner walls of said housing spaced apart, an elongated door bolt disposed between said housings and extending horizontally therefrom, a pair of longitudinally arcuate operators disposed one in each housing, a reduced diameter stud carried by each operator -journalled in an inner wall. a polygonal shait'xed to each of said operators and also fixed to said bolt whereby rocking of a selected operator-will rock-said-bolt upwardly to released position, a. locking lug for said boit, xneans pivotally supporting said lug from one of said housings above said boit, an-
