UNITED STATES PATENT OFFICE.
GOTTLIEB YUNKER, OF NEWARK, NEW JERSEY, ASSIGNOR TO NEWARK CORNICE AND SKYLIGHT WORKS, A CORPORATION OF NEW JERSEY.
AUTOMATIC FIRE-WINDOW.
Specification of Letters Patent.
Patented Nov. 20, 1906.
To all zul/t0n@ t TV1/Ly concern:
Be it known that I, GOTTLIEB YUNKER, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Automatic Fire-VVindows, of which the following is a specification.
This invention relates to automatic firewindows, and more particularly to the upper sashes of such windows and means for quickly alllid effeotually closing the same in event of a The objects of the invention are to simplify such closing means 5 to reduce the labor and cheapen the cost of manufacturing the same to secure a construction which shall be largely hidden or concealed, and thus to improve the appearance of the window; to obtain maximum efficiency, and to secure other advantages and results as may be hereinafter set forth.
The invention consists in the improved automatic fire-window, substantially as herein described and claimed.
Referring to the accompanying drawings, in which like numerals of reference indicate corresponding parts in each of the several iigures, Figure 1 is an elevation of a window of my improved construction from the outside thereof, the upper sash being shown lowered. Fig. 2 is a vertical section showing the upper sash cut centrally and the lower sash partly through one of its panes, as upon line x x, Fig. 1. Fig. 3 shows in elevation a single-pane sash to which my invention is applied, and Fig. 4 is a top-edge view or plan of the same.
In said drawings, 2 indicates a windowframe of any construction suited to fire-windows referably of sheet metal. This frame provi es at the inner faces of the upright sides channel 3 4 for the upper and lower sashes 5 6 to run in, said sashes being also formed of sheet metal, with panes of glass 7 mounted therein. The said sashes are free to slide vertically past one another, as is common in windows, and in the drawings I have shown said sashes as balanced or connecte'i by chains 9, which run over pulleys 10, stationed at the upper part of the windowframe. It will be understood, therefore, that opening or closing one sash causes a similar movement of the other sash, and the two sashes will stand normally at any point where they are left.
In carrying out my invention to secure means for automatically closing such a window as described in case of fire I have hollowed or recessed the rail or lower transverse portion 22 of the upper sash 5 from its bottom upward, as clearly shown at 23 in Fig. 2. This recess is adapted to receive and normally contain a weight 11, which may be simply a bar of cast-iron or other suitable material.
At the top of the said sash 5 is arranged an inverted-Ushaped bracket 12, from which depends a fusible link 13, said link lying above the top of the window-sash and being arranged in vertical alinement with the middle upright bar or mullion 14 of the sash. This bar or mullion is of course formed of sheet metal, like the rest of the sash, and therefore hollow, and inside of the same I arrange a rod 15, connected to the weight 11 at its lower end and at its upper end to the fusible link 13.
If at any time when the window is open, a iire breaks out and sweeps through the said window, it will melt the fusible link 13, and thus release the weight 11. This will destroy the equilibrium of the sashes, and the overbalancing lower sash will consequently close the window. Obviously a recess 16 must be provided in the upper part of the window-frame to receive the bracket 12 when the upper sash is closed.
It will also be obvious that in case of window-sashes having no center bar or mullion 14 I can equally well arrange the rods which support the weight 11 in the opposite vertical side pieces or stiles 17 of the sash, as shown in outline at 18 in the drawings. The brackets 19 for the fusible links 20 are then similarly disposed upon the top of the sash and recesses 21, provided in the windowframe. Furthermore, it will be understood that my invention can be applied to windows having other than balanced sashes, since the particular means herein described could be utilized to close the upper sash alone, and other means-such, for instance, as shown in Patent No. 810,595, issued January 23,1906h be employed for the lower sash.
Another construction for sashes having no mullions is illustrated in Figs. 3 and 4 of the iraWingS, where 24 indicates. such a sash having a large central pane of glass 25. Here the rods 26 for the weight 27 run up through IOO the stiles 28 and at their upper ends have chains 29 29 connected thereto,which extend inwardly toward each other through grooves or recesses'30 30 in the top of the sash,
A bracket 31 is mounted centrally upon the top edge of the sash, and from it depends by one arm 33 a three-armed fusible link 32, Whose two lower arms 34 34 are connected one to each of the said chains 29 29. Thefeet 35 of the said bracket extend across the grooves 30 30 in the sash and serve to confine the chains 29 therein. Other detail modifications could obviously be made without departing from the spirit and scope of my invention, and I do not wish to be understood as limiting myself by any of the positive descriptive terms herein employed except as the state of the art may require.
Having thus described the invention, what I claim is- 1. In a window, the combination with a sash, of an exposed fusiblelink carried on the top of said sash, connecting means extending downward on said sash from said link, a-
weight supported by said means upon the bottom of the sash, and counterbalance means for said weighted sash.
2. In a window, the combination with a sash having in its lower part a downwardlyopening recess, of a weight in said recess, an exposed fusible link on the top of said sash, means extending from. the said link to said weight and supporting the same, and means counterbalancing said weighted sash.
3. In a window, the combination with a frame, of a vertically-slidable sash and means for causing the same to move upward, said frame being recessed above said sash, a bracket upon the top of the sash adapted to enter said recess, a fusible link supported by said bracket, and a detachable weight at the lower part of the sash supported by said link.
4.' The combination with a sash having a recess at its lower part and a hollow upright portion, and means for causing said sash to move upward, of a detachable weight in said recess, an exposed fusible link at the top of said sash, and connecting means extending through said hollow upright portion from the weight to said link.
5. The combination with a sash having a recess in its lower edge and a hollow center mullion, and means for causing said sash to move upward, of a weight in said recess, an exposed fusible link at the top of the sash, and a connection between said weight and link extending through the said mullion.
6. In a window, a frame recessed at its top, a sash having its lower edge longitudinally recessed and having a hollow upright portion, means for causing said'sash to move upward, a weight concealed in said recess of the sash, a bracket upon the top of the sash, and a fusible link depending from said bracket and connected through said hollow upright portion with said weight, said bracket and link being adapted to enter the frame-recess and be concealed.
7. In a window, a sash having in its lower part a downwardly-opening recess, a weight in said recess, a bracket extending upward from the top of said sash, a fusible link depending from said bracket and being exposed above the top of the sash, means on the sash connecting said link and weight, and counterbalance means for such weighted sash.
8. In a window, the combination of upper and lower sashes counterbalancing each other, the upper sash having on its top an exposed fusible link and on its bottom a loose weight connected to said link.
9. In a window, a sash having at its lower edge a longitudinal groove or recess with closed side walls, a weight concealed in said groove or recess, a fusible link carried on the sash and exposed above its upper edge, connecting means extending between said link and weight, and counterbalance means for the weighted sash.
