Specification of Letters Patent.
Patented Dec. 2'7, 1910.
Application filed February 11, 1910. Serial'No. 543.336.
{locking means for fireproof swinging doors upon the eneral construction an arrangement disc osed in my co-pendin application,-Serial Number 530,287, and t e. especial object of the improvements forming the subject matter of this application is to provide locking bars that will lock two hinged doors together and to the frame in which they are hung without the 'aid of springs, and in which the action of gravity is utilized in the locking 0 rations.
A furt er object of my improvements is to provide locking means having as few' parts as possible, and to so combine and ar-- range these that they will operate efi'eetively and easily under all the conditions affecting devices of this character.
An additional objectis to provide means whereby the door arranged to be closed in advance of the other must always be closed in that order.
Various other special objects and advan tages are obtained by my improvements as will readily. appear to those skilled in the art to which this invention relates.
In the accompanying drawing which forms a part of this application, I have shown my im rovem'ents in a preferred form in the to lowing views Figure'l. is a vertical sectional view of a portion of a hollow metal door to which my ocking mechanism is ap lied, the latter being shown in elevation; ig. 2 is a vertical cross-section of the lock-stile of the door shown in Fig. 1, with an edge-view of, the lockin arts; Fig. 3 is a vertical crosssection 0 t e lock-stile of the-companion door to the one shown in Figs. 1 and 2, and Fig. 4 is a vertical section of a portion of the com anion'doorwith its locking bars shown in e evation Referring to the details of the drawing, 5
represe ntslthe"hollow lock-stile of a swinging sheet metal 'door hereinafter called for convenience, the left-hand door and 6, 001- respondingly illustrates the lock-stile ofthe companion door, hereinafter called the righthand door. The meeting edge of the stile of the left-hand door is provided at equidistant points with openings 5*, and the corresponding edge of the right-hand door is provided with openings 6 which register with the openings 5 when the doors are closed. A knob-spindlefi" extends through the stile 5 and is provided with knobs 5 on its ends in the usual manner. Mounted on the spindle within the stile, is a circular plate 7, on which are pivoted two curved links 8 and 9, near the outer ends of which are slots which effect a limitedsliding engagement of the links with a pin 10 projecting from the adjacent side of the latchbar 11. v
The latch-bar 11 extends nearl the entire length or height of the door. t is a flatmetal bar provided along one edge with inclined tumblers or bolts 11 which areadapted to slide easily through the openings 5, the walls of the latter bein inclined to cor respond with the edges of the bolts. The latch-bar 11 is slidingly mounted in three metal straps or keepers 12 which are riveted to one side of the door stile and have slideways adapted to permit lateral as well as vertical movement to said bar. Each of the straps 12 has a slot 12 cut diagonally therein, the inclination of which corresponds to that of the bolts 11'. Slidin 1y fitted in each slot is a pin or bolt 12* whic is fixed in and projects from the bar 11.
At the upper end of the bar 11 a pin 11" is fixed so as to project outwardly toward the contiguous face of the door, and extends This pin is so positioned that when the door is closed against the door stop 19 said pin will pass through the hole 14 and strike" against the pin 11 (the bar 11 being raised) strap 19? of the lintel 1901f the door-frame.
and push the latter with the bar inwardly.
As soon as the pin H" is pushed through the hole in the door it will he l'rcc to slide in the slot I l" and gravity will causolhe liar ll to drop and thereby project the bolts through the openings 5. The deflection ol the bar It resulting from the action of the pin 15 is indicated by full lines, Fig. 2.
In the lock-stile of the right-hand door are slidingly mounted locking-laws"lfi and 16, both of which are preferably square in crosssection, but bar 15 is somewhat heavier than harlG. Bar 15 is pivolally connected with a circular late 15% on the knob spindle 17 by a short link 15*. Bar It; is directly pivoted on said plate at a point nearly diametrically opposite the pivotal connection of the link 15. The lower end of the bar 16 terminates in an outward and downward hook shaped extension 16, which occupies a position oppositethc central opening '6". The bars 1:") and 16 are vertically slidahle in keepers 17 riveted to one side of the stile, and their ends are adapted to be. proected through openof the latter a hole is provided which is ar ranged to receive, when the door is closed a pin 20 which projects from the door stop it) so that its end will strike against. the ha 1' t6 and push it: from the contiguous wall of the stile. It will he noted that the hole 6 in the. top of the. door is out of alinement with the bar 16 when the latter is in its unlocked or unprojeeted position, so that the end of said bar unless pressed by the pin 20, will lie under the portion of the top rail wall adjacent to said hole, and that when in suchposition it will be prevented from passing through said hole. So that, when the. right-halal door is free from contact with the pin 20,
. which it will always be when the door is open, and the bars 15 and 16 are retracted,
gravity cannot act to proj ct the bars, for, though the hea\ier bar.15 in its downward movement would push upward the bar'16 if the'latterwcre not held againstsuch action,
it wouldbeimpossibleiforsuch action-to 'ta kc pluco so longns the upper and of the l)tll"16 abuts against the top wall of the top rail of the door, as indicated by dotted lines, Fig; 3.
It willbe understood, that a very slightdeviation of thebaf's 11 and 16 only is required to elleet the operations above described, and this will be permitted by the nature of the material from which sail bars are made, the location of the keepers 12 and 17 respectively and the slight deflection effected by bending the bars as indicated in Figs. 2 and 3.
When the latch-bar ll is projected, its middle bolt 11" will lie iii-close proximity to the outer edge of the hook 16 as indicated l by dotted lines, Fig. 4, and it will be obvious that when in such position, the bar 16 cannot be moved, its pivotal connection with the plate 1.8 being such that when projected or in locked position, it can only be moved downwardly and its slnipc being such that when moved downwardly,the hook 16 will move outwardly or toward the bolt; 11. llcnce it will be necessary, to effect the opening of the right-hand door, that the latch on the left-hand dooluhe first, operated'to disengage it from the right-hand door. The
ot' the bar 16 is provided for by leaving the strap 17" opcn'at the side toward which such movement takesplace.
The unlatehing of the bar it, may be pre vented by a lock 13 secured within the stile a and so arranged that its bolt, when projet-ted, will impinge against, the rear or inncr edge of said bar, as indicated in Fig. 1.
It will be noted that the relative arrangement of the slotted curved links 8 and 9 and disk-plate T, is such-that. said links will lift the bar irrespective of the direction in which the knob-spindle is turned.
in opening the lefthand door the knobspindle 5 is turned, thus raising the bar 11 and freeing the bolts 11" from the openings (r in the. companion door or in whatever 'openings may-be provided therefor. As the door is swung on its hinges the pressure of the pin It)" will he released from the pin 11 so that the latter will be forced into the hole ll" in the door opposite the upper end of the slot 14, and as soon as the ln enters said hole the pin will be held therein and thus the bar [1 will be held in its inoperative POSI- tion until the left-hand door is again closed. It the lefth'and door should by inadv'er'tence be closed inadv-anceof the right-hand door, the bolts 11* would projectand thus the right-hand door would'lsbrike against; them and closing be made impossible, hence it w ll be. seen the locking mechanism is so conalways be closed and opened in the predetermined order.
