The opposite ends Simplification of installation and perfect harof members It and H are also inwardly bent-' and the portion 2| of the former is welded or formed integrally with a bearing portion which, in the form shown, comprises a circular block 22 of about the same thickness as the glass plate. This portion may rotate in any suitable female bearing or journal, e. g., a sleeve which may, as shown, be a block 23 of the same thickness as the glass and having an opening for the reception of the portion 22. The block is mounted in opening 24 in panel l2, the edges of the opening being protected by a packing 26 of more or less plastic or adhesive material to prevent direct contact of metal and glass. 6

Block 23 is secured from displacement by means of clamping plates 21 and 28, having openings 29 and 3| pierced therein for the admission of handles l6 and I1. One of the plates, e. g. 21, may be secured to block 23 by welding while the other is releasably secured, for example by means of screws 32 shown in Figs. 2 and 3. Screws may even be employed to secure both plates, if so desired.

Handle ll may be secured to block 22 by welding, or as shown in Fig. 5, the rear face of the block may be formed with a lug 33 adapted to fit within a notch in a disc 34, to which the extremity of the handle I1 is welded or otherwise secured. When the structure is assembled, plate 28 secures the key from outward displacement.

In order to secure the handles I6 and H in position to act as simple latches, plates 21 or- 28 may be provided with lugs 35 and 36, engaging lugs 35a and 3611 upon the portions 2| which function as stops to limit the extremity of their are of swing to the position shown in Fig. 2.

If itis desired, positively to lock the handles from displacement, suitable locking mechanism may be provided. The locking mechanism may behoused in block 23 and the notches formed in bearing 22. For example, the lock may be of the tumbler type and include a lock cylinder 31, corresponding substantially to that in an ordinary night latch. The cylinder which is disposed in openings 38 and 39, formed respectively in block 23 and plates 2! and 28, includes clamping plates 4| and 42.' These are secured together by studs 43 welded to plate 4|, and by screws 44 threaded through plate 42 into the studs.

The internal mechanism of the lock is not a part of the present invention, and since it is well understood by those skilled in the art, it is not deemed necessary to describe it in detail. It includes suitable tumblers or equivalent devices (not shown) disposed in a rotatable barrel 46, best shown in Fig. 2 and operatedv by means of key 41, which is inserted through key hole 48 in the end of the barrel.

The barrel 46 at its inner extremity carries a pawl 5| designed to engage a lug 52 upon the side of a locking bolt 53 for the purpose of retracting the latter. The bolt at its upper extremity is provided with an enlarged portion 54, sliding in a passageway 56 in block 23. Notches 51 are formed in the outer periphery of bearing 22 in position to be engaged by the extremity of bolt 53 to lock the handles I6 and IT in either of the positions shown in Figs. 2 and 3.

' The bolts 53 may also be actuated from the rear face of the door by a thumb latch mechanism. This mechanism comprises a thumb knob 58 attached to a stem 59 which rotates in an 'opening in plate 42 and at its inner extremity attaches to barrel 46 to actuate the later independently of the key.

Assembly and operation of the mechanism is self-evident. Assuming that the openings 24 have been provided in the doors l2, and that the latter have been hung. The packings 24 are placed about the edges of the openings and blocks 23, having bolts 53 in position in passages 56, are secured in the latter. Subsequently plates 2'! are slid upon handles l6 and bearings 22 are slipped into position in blocks 23. The handles having plates 28 thereupon are then secured by setting discs 34 upon bearings 22. By threading screws 32 through the plates into blocks 23, the various parts are secured from dis placement. The next operation of assembly involves securing cylinders 31 in place in openings 38 and 39, and then securing plates 42 by means of screws 44. Finally knobs 5B are secured to stems 59 and assembly is complete.

Where the bars I6 and I! are to function as simple handles they are rotated to vertical position, as shown in Fig. 3 and secured in that position by actuation of bolts 53 to engage the appropriate notches 51 in the members 23.

If the bars are to function as latches or locks, they are rotated to the diagonal positions shown in Fig. 2 and are there secured by the lock bolt in notches 51.

The construction is extremely simple and compact and requires but a single simple opening in the glass, which opening is easily formed by sandblasting. No mortise in the edge of the glass for thebolt is required. 3 1

The embodiment of the invention herein shown is merely exemplary, numerous modifications may be made therein without departure from the spirit or scope of the claims.

,What I claim is:

1. A latching device for double swinging doors of temperedglass comprising a block adapted to be mounted inan opening in a door, the block having a circular opening extending therethrough, a rotatable block mounted in the latter opening, handles rigidly secured to the latter block and being laterally bent to provide a member of C shape, the ends of which are adapted to engage upon opposite sides of a second door, and means to secure the first-mentioned block in place in the opening in a the door, said means comprising a plate secured to the block and providing a flange engaging the portions of the door adjacent the opening, a second plate secured to the opposite side of the block by means of a screw fastening and providing a second flange engaging the remaining side of the door, said plates having openings therein through which the handles extend the rotatable block being formed with notches about its periphery and detent means disposed in the first-mentioned block and selectively engaging the notches to secure the rotatable block from rotation in a predetermined position.

2. A combined handle and securing device for double doors, which doors comprise two panels, each panel being mounted to swing in a doorway about its edge, remote with respect to the other panel, said devices comprising a pair of 3 handle members, one for each panel, and being approximately of C shape, the intermediate portion of each member being journaled in a bearing block disposed in an opening formed in its corresponding panel, each member having its extremities projecting from opposite sides of its panel across the edge of the adjacent panel and constituting locking means securing the panels against rotation and being rotatable in its bearing block to a position out of its locking relation.

3. A construction as defined in claim 2 in which means is provided selectively to secure the handle members from rotation when functioning either as a lock or when rotated to a position out of locking relation.

4. A construction as defined in claim 2 in which notches are formed in the intermediate portions of the rotatable members and movable detents are provided in the bearings adapted to engage the notches selectively to secure the rotatable members in predetermined position.

5. A latch construction for a door panel, which panel has an opening formed directly therethrough adjacent to one edge, the edge being free to swing about the opposite edge as an axis, said latch construction comprising a member approximately of C shape, the intermediate portion of which is journaled in a bearing block in the opening, the bearing block being secured by plates attached thereto and clamping opposite sides of the panel, the member being rotatable from an approximately vertical position in which it acts as a handle, to position in which it engages upon opposite sides of a second panel adjacent to the swinging edge to lock the door panel in closed position, the intermediate portion of the member being notched and movable detent means housed in the bearing block selective to engage the notches and secure the member in either of its positions of adjustment.
