My invention comprises latch-operating mechanism, the operating members of which, on opposite sides of the door,.-are both arranged to be operated to raise the latch, i. 6., to release the door, by movement of the operating member inthe direction which thedoor swings to open.
The object of my invention is to provide A an improved, simple and effective latch for use on emergency doors. I willnow proceed to describe my nven tion with reference to the accompanying operating mechanism, particularly adapted drawings, wherein two embodiments, thereof are illustrated, and will then point out the novel features in claims In the drawings: Figure 1 shows an exterior elevation of..a door fitted with my improved latch-mechanism;- Fig. ,2 shows a fragmentary interior elevation, on a larger.
scale, of the portion of the doorcarrying- .such latch mechanism, and particularly illustrates the interior 1atch-operat iigdevice. Fig.3 shows a fragmentary trans;
verse section through the door and latchoperating mechanism, the section vvbeing taken on the'line w-w of Fig. 2. Fig. 4
shows a side elevation of an alternative form of latch mechanism; and Flg. 5 shows a transverse section of such latch mechanism I p on the line g y.of Fig. 4.
- Referring first to Figs11, 2 and 3, 1 designates the door and 2, 2 hinges therefor. 3, 3 indicate ordinary gravity-depressed latch-bars for holding this door closed and 4, 4 illustrate the ordinary latch-bar catches or striking plates for-these latch-bars. I have indicated that the three latch bars 3 are connected by a vertical link 5; this being .a common arrangement for fire doors and the like, and being an advantageous ar 'rangement in that. one latch-operating mechanism serves for all three latch. bars. 6 designates a handle for raising the latch 'lar casing 14.
.frolfi the oustide of the door,and 7 designates a handle or operating bar for raising the latchfrom the inside of the door, this bar 7 ,being a bar extending horizontally" across thefidoor, through a greater or less Patented June 18, 19.12;.
portion of its width, s preferredsaid bar7" being connected at its ends, by links 8, to a squared pivot-shaft 9 suitably supported and passlng through a correspondingly squared orifice in a lever 10 extending transversely through the door directly beneathone of the latch-bars It will be seen that motion of the. interior operating member? in the direction of the arrow shown in Fig. 3, will raise the lever 10, and in so doing will raise the latch-bar or bars v3. It will also be seen that, normally, the weight of these latch-bars 3, and of their connecting link 5,
acts downwardly upon the lever -10 to hold the bar 7 out and to hold thelatch-bars3 in.
locking position. The exterior operating member 6 is suitably pivoted to the door and is provided with a cam portion 11 arranged to act upon the under side of lever 10; whereby, when said member 6 is-.I I1oved in the direction of the arrow, that is to say, in
the direction in which the door swings'when opening, the lever 10 is raised, so raising the latch-bar or bars 3. It will be seen therefore that whether the door is to be 0' ened from the outside, orfrom the inside, .t e latch-operating member to. be operated r ,to open. that 'do'oris moved in the direction in which thef'dooristo inove a; open. the, alternatlve construction, shown.1n
Figs. 4' and 5, "the latch-bar3 isheld depre'sse'dnormally, not only by gravity, but also by the action of a spring 12. The latch operating mechanism is the same as that shown in Figs. 1, 2 and 3. This construction shown in Figs. 4 and 5 is desirable in some cases, since it permits the inclosure of the principal portion of the latch-operating mechanism, and also the, inclosure of the latch, within a casing, 13, giving the latch the appearance of a'rim lock. When such construction is used, it is generally preferable'to inclose the latch-bar catch in a slim- What I claim-is lfiA'door latch mechanism comprising in combination one or more latches adapted to beraised to release a door, and operating means therefor comprising a pivoted member extending transversely beneath one of said latches, and an operating member connected to said pivoted member and arranged when moved in the direction of opening of the door to raise said plvoted member and thereby the latch or latches,
and another operating member upo'n the opposite side of the mechanism pivotally supported and having 'a' cam portion engaglngsaid transversely extending pivoted 1 member and arranged, when said second operating member is moved in the direction 0 7 opening of the door, to raise said transver'sely extending pivoted member, and
