This invention is a latch characterized, in its preferred form, by a flanged bolt adapted tooscillate about its axis as we'llas to reciprocate longitudinally in a pressed metal housinghavinlg reversely disposed cams for per-, ating. the bolt in reversed positions therein in combination with a keeper adapted tobeengaged by the boltso, as to be drawnup and held against lateral or longitudinal movement with relation to the bolt.

The primary ob ect of my improved constructionis to provide a simple and strong device that cannot be opened from the outside and canbe applied to slidlng orswinging doors, windows or the like, seas tosecure them in closed position, as also'to draw them the lines l*l of Fig. 3; Fig. is a section- 211 view taken through the housing and bolt on the line 5 5 of Fig. 3; Fig. 6 shows. a brokensection of a door together with an elevation of the keeper and a section of the bolt disposed therein in the unlocked position. and Fig. 7 is a view similar to Fig. 6

i with the bolt turned in locked position.

The latcln-in, the form thereof illustrated in the drawings, comprises a sheet metal housing cut and pressed to shape so as to provide in an integral construction the flat parallel bearings 1 lying ;in a plane and the arch 2 connecting them and extending parallel thereto. This arch hast-he trans.

verse sections 8 separated therefrom on para allel lines 4: and bent downwardly to semicylindrical form to provide bearings for cooperation with the semi-cylindrical bear ings 5 formed by the crown of the. arch.

An opening 6 is formed in the arch midway of its length and has the oppositely in clined edges or cams 7 having the terminals.

7 which. may be approximately at right angles to the'length of the arch. A bolt8 is adapted to move longitudinally and rock in the bearings 4" and 5 and a stem orihandle 9 isfixed, to the bolt transversely thereto so asgto project through the openingfi and act against a cam]. An end of thei lQlt has thereon the flange or cam 10 which is adapted to pass througlran opening 11in for engagingthe keeper so as to prevent the withdrawal of the bolt therefrom. a

The housing has a lug 13 cut and bent up from the bearing 1 adjacent tothe contracted way between the cams 7,this lugcontaining an openingl adaptedfor the passage oi the 'yoke 15 of" a lock 16 for securing the stem or, handle 9to"the yoke and fixing the bolt'6' in the securingposition.

Itwill be: observed that as the terminals 7 of the'cams 7 are disposed substantially at right angles to the bolt 8 they effect an approximately square engagement with tl e stem or handle 9 to retain the same in position for holding the bolt in the secured position- The. housing, by reason of its symmetrical construction, is adapted for use with the bolt in reversed positions so that the latch is applicable to right or left hand connection. v

As illustrated in to oscillate upon the hinges 18 is secured in the closed position to the jamb 19 by means of my improved latch. This is effected by passing the screws 20 through the holes 21 in the housing bearings 1 and thence into the jamb to secure the housing thereto. The

keeper 22 is screwed to the inner face of the a door adjacent to thedamb by. passing through the'holes 23 in the keeper and into the door the screws 2st, the opening 11 in the keeper being disposed so that theflanged end of the bolt will pass therethrough in the elevated position of the stem or handle 9 and turn in a socket 25 in thedoor large enough topermit such flange. to engage the keeper. i I

The door being closed and the handle 9' being elevated, the bolt 8 can be shot for ward so that the flange 10 passes through the opening 11. The handle 9 is now turned downwardly and the cam I a draw the bolt back in the housing so that J 7 acts thereon to as the flange turns into position for engaging the keeper 12, it is pressedjagainst, the same to draw the door firmly against the jamb, the handle engagingthe section 7 Fig. 1, a door 17 adapted 7 a'keeper 12 and to be turned into position lower end of the openingG so as to lie mi'dat the bottom of the cani7 tohold it in the desired securing position, where it can be secured by lock 16. It will be understood that a door, window or the like, when thus secured, is held firmly against its hearing so that a device cannot be entered between the two to undo the lock, rattling is prevented and an approximately air tight or Water tight joint can be made.

As illustrated in Fig. 2, the latch is applied to a sliding door 26 by fixing the housing bearings 1 to the jamb 27 and fixing the keeper 22 to the inner face of the edge of the door adjacent to the jainb, by which the flange 10 on the end of the bolt 8 can be engaged Within the keeper not only to lock the door against sliding, but also to draw it tightly against its jamb so as to prevent the entry of an opening device to form a tight joint and to prevent rattling.

It will be understood that the parts 17 and 26 may be windowsas Well as doors and that the latch has the same advantages in securing windows as doors.

Having described my invention, I claim:

1. A latch having a pressed metal housing comprising bearings connected by an arch I having sections bent downwardly'therefrom to provide with said arch a way, sald arch having a cam formed therein, transversely to the length thereof, and a bolt adapted. to

rock and move longitudinally in said way, said bolt having a device projecting laterally therefrom so as to coact'with said cam, whereby said bolt is moved longitudinally when it is rocked.

2. A latch having a keeper provided with bearings, one of said bearings having a lug thereon, and an arch connecting said bears ings, said arch having sections bent down, wardly therefrom to form therewith away 1
