FIREPROOF WINDOW.

i Specification of Letters Patent.

Patented March 27, 1906.

Application filed December 12,1905. Serial No. 291,443.

To all whom it may concern.-

Be it known that I, WILLIAM HENRY MIL- LER, a citizen of the United States, residin at Galveston, in the county of Galveston and State of Texas, have invented certain new and useful Improvements in-Fireproof Windows; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in window construction, and it is more particularly an improvement upon the construction disclosed in my application for United States patent filed September 20, 1905, Serial No. 279,317.

The object of the invention is to simplify the construction so that the same can be made at a great reduction in cost.

Another object is to provide means for automatically closing the lower sash when subjected to a predetermined temperature, said sash being prevented from dropping with such violence as to injure it.

WVith the above and other objects in view the invention consists of certain novel features of construction and combination of parts which will be hereinafter more fully described, and pointed out in the claims.

In the accompan 'ng drawings I have shown the preferred orm of my invention.

In said drawings, Figure 1 is a perspective view of a window frame and sashes constructed in accordance with my invention. Fig. 2 is a vertical section therethrough. Fig. 3 is a horizontal section-through the lower sash and the adjoining portions of the frame. Fig. 4 is a front elevation ofa portion of the top rail of the upper sash and showingin dotted lines the position of the weight-holding receptacle therein- Fig. 5 is asection on line :0 112, Fig. 4. Fig. 6 is a vertical section through the lower portion of the Windowframe and showing in elevation the closure in positiomover the weight-receiving aperture. Fig. 7 is a detail view of said closure. Fig. 8 is a perspective view of the adjoining ends of the fixed and removable section of one of the parting-strips, a portion of the fixed section being broken away to show the end of the removable section therein. Fig. 9 is a perspective view of a portion of the removable section of the parting-strip looking at the same from inside of the window-strip and showing the means for detachably secur- 6-is held within the ing said parting-strip to the window-frame. Fig. 10 is a perspect1ve.view of a portion of the window-frame looking at the same from the inside thereof and showin the manner of permanently fastening the cad-strip to said frame. Fig. 11 is a section throu h a modified form of bead-stri and the ad oining portion of the window-flame. Fig. 12 is a detail view of a nut adapted to be used in connection with the fastening means shown a in Fig. 9; and Fig. 13 is a section on line y y,

Fig. 2.

Referring to the fi ures by numerals of reference, 1 1 are the si es of the window-frame, and 2 and 3 are the head and sill, respectively. all of said parts being connected at their ends by rivets 4, so that a solidlyconstructed frame is produced after the manner described in my application, hereinbefore mentioned.

he inner or adjoining faces of the sides of: the window-frame are provided with channels 5, and in each of these channels is disposed a parting-strip formed of two sections 6 and 7, res ectively, each of said strips being substantially U-shaped. .The upper section channel by means ofbolts 8, which screw into nuts 9, soldered or otherwise permanently fastened inside the side 1 I of the window-frame. The u per sections 6 of the arting-strips extend ownward to a point 0 ose to the center of the window-frame and receive the tapered ends 10 of the lower members 7 of the parting-strips. It is obvious that the u per ends of these members 7 are held secure y in place, because they project into the upper members.6. The lower portions of the members, however, are detachably fastened bymeans of bolts 11, which extend through keyhole-slots 12 in the inner walls of the channels 5 and engage nuts 13, which normally overlap and are soldered to the edges of the contracted portions of slots 12, and therefore prevent the withdrawal of bolts 11. Instead of providing an ordinary form of nut upon the bolts 11, I can use a nut 14, such as shown in Fig. 12, and which has its opposite edges grooved, as shown at 15, to receive the edges of the contracted portion of each slot 12. With this arrangement the nut'will be held against rotating, and loosening of the bolt is practically prevented.

Narrow channels 16 are formed within the adjoining faces of the sides 1 for the reception of bead-stri s 17. The beads of these strips may be 0y indrical, as shown in Figs. 3

it o

and 10, or, if preferred, can be angular, as shown in Fig. 11 at 18. In either caseeach bead-strip is formed of an upper section 19 and a lower section 20, the upper section be ing immovably fastened in place by slitting the walls of the channel, as well as that portion of the strip therebetween, and then folding back the walls and strip, as shown at 21 in Fig. 10. The upper sections of the beadstrips are thus permanently secured without the use of solder or other like means.

The lower portions 20 of the bead-strips are adapted to he forced into the channels 16 and can be detachably held by means of bolts 22, which screw through the lower portions of the channels 16 and the strips therein, said screws being inserted into the sides 1 of the frame from the inside faces thereof, as shown particularly in Fig. 3. A partitioni28 is located within one of the sides 1 and is riveted or otherwise fastened to one of the walls of said side. Another partition 24 is fastened within each side 1 by means of the bolts 8. It will therefore be seen that one partition is located within one of the sides 1, so as to divide said side into two compartments 25 and 25, while two partitions 23 and 24, respec tively, are disposed within the outer side 1 and divide said side into three compartments 25, and 27. The partitions 24 are only employed where the window-frames are very long, and long balance-chainsare necessarily employed in order that weigi'its maybe conveniently coi'mectcd to the b alarms-chains, openings 28 are formed. in the s es 1 and are of sufficient size to permit an ordinary balance-weight to be inserted ther rough. Each of these openings i located between. one of the pa t ing-strips and bead strips and is adapted to he closed by means of a plate 29, having side flanges 30, which are inserted into the openand lit snugly against the sides thpreof. One end 31 of the plateill is inserted iinder the upper edge of the opening 28, while the opposite end of plat- 9 overlaps the lower of the opening and has an aperture a r the reception of a M hiring-bolt lloth sashes arc construe s after the man:

nor described in my former application, the only exception being that the upper sash has a weight-receptaele 35 in its upper rail, whic secured in place by the same rivets which fasten the parts of the upper rail together. This re ieptacle is trougleshaped, as shown particularly by dotted lines in Fig. 4, and is adapted to contain a desired quantity of shot 37, adapted to escape through an openimg- 38, which, however, is normally covered by a fusible closure 39, having a stem extending upward therefrom and above the upper rail of the sash. This upper sash is supported in the ordinary manner by means of balance-weights 41, (shown by dotted lines in Fig. 3,) said weights being; conerases nected to the sash by means of chains. (Not shown.) T he lower sash 42 has a rod 43 extendingvertically through the center thereof, and where a mullion-bar is employed this rod extends therethrou h, as shown in Fig. 2, and where no mullionar is used the rod is located adjacent one face of the glass. In both instances the lower end of the rod is secure-d to the bottom of the lower sash by a fusible tip 44, while the upper end of the rod, which projects above the ower sash 42, has an eye 45, to which is secured one end of a chain 46. This chain extends through the head 2 of the frame and over a'pulley 47, mounted on brackets 48 within said head, and from this pulley it extends over a second pulley 49 within said head and downward into the compartment 27, where it is con nected to a small weight 50.

Ordinary balance-weights 51 (shown by dotted lines in Fig. 3) are connected to the lower sash by means of chains 52, and the we'ghts 50 and 51 combined serve to balance the lower sash and support it in any position to which it may be moved.

The chains 52 are preferably connected to the sashes in the manner shown in Fig. 3, where it will be noticed that the end link of each chain 52 is engaged by the stem of a bolt 53, the head of which is located within the side rails of the sash and is soldered or otherwise fixedly connected thereto, while a nut 54 is disposed on the bolt and serves to clamp the chain-link against the side of the sash.

The partitions and 24 serve to prevent the weights and their chains from becoming entangled, and while the partition 23 is al ways employed the partition 24 may, as heretofore stated, be dispensed with, except where the balance-chains are of considerable length.

in windows of extremely large size the weights of course can be inserted through openings 28, and in such cases it would be necessary to place them in the sides 1 before the masonry has been built around them.

it is to be understood that under ordinary conditions the sashes are perfectly balanced by their respective weights and can be supported by them in any desired position with in the frame.

Should the sashes while open be subjected to a predetermined degree of temperature, the fusible closure 39 will be melted so as to uncover the opening 38, and the shot 37 will escape therethroug i and reduce the weight of the upper sash, so that the balances 41 will promptly raise said sash into closed position. will be melted and release the rod 43 from the lower sash 42. Said sash will therefore be relieved. of the sup port given by weight 50, and as the remaining weights 51 are not sullicient in themselves to support the sash 42 At the same time the fusible tip 44 said sash will move downward into closed position, but will be prevented from dropping violently, because it Will be retarded by the weights 51. r It will of course be understood that various changes in the form and minor detalls may be resorted to Without departing from the scope or spirit of the invention.

What I claim is 1. The combination with a sheet-metal Window-frame having channels in the sides thereof and slots in the Walls of the channels, each having a contracted portion of a sec tional parting-strip in each channel, means for permanently securing one of the sections Within the channel, the second section having one endprojecting into the permanently-secured section, and means engaging-the-Walls of the slots for detachablysecuring said second section within the channel.

2. The combination with a sheet-metal Window-frame having channels'in the sides thereof and slots'in the Walls of the channels, each having a contracted portion of a sectional parting-strip in each channel, means for permanently securing one of the sections within the channel, the second section having one end projecting into the permanentlysecured section, a grooved device slidably mounted Within the contractedportion of the slot, and means engaging said device for detachably securing the second section Within the channel.

3. The combination window-frame having channels in the sides thereof, of a bead-strip seated within and extendin from each channel, the Walls of the channe and the'strip therein being slit and folded to retain the strip.

4. The combination with a sheet meta'l Window-frame having a channel therein, of a sectional bead-strip within the channel, one of said sections and the walls of the channel adjoining it being slit and folded to hold the 4 5 section within the channel, and a second secwith a sheet metal end adaptedto be j ect into the aperture and under one end wall anges upon the plate project-- thereof, side 'ing into the aperture, and an end projection upon the plate adapted to overlap and to be secured to the other end Wall of the aperture.

6. The combination With a sheet-metal- Window-frame, of a parting-strip adapted to be secured thereto and comprising channeled sections, one of said sections having a reduced inserted into the other section.

7. The combination with a Window-frame having partitioned sides forming com artments, and pulleys within the head 0 the ame, of a sash within the frame, a rod slidably mounted therein, fusible means for holdin the rod against movement in the sash, balances within the frame and permanently connected to the sash, a chain connected to the rod and extending over the pulleys into ..one. of the compartments, and an'auxiliary weight suspended in' said compartment by the chain: V

8. The combination with a sheet-metal sash having a top rail formed of interlocking metallic strips; of a trough-shaped receptacle in the top railof the sash and .havin opening in the bottom thereof and through the bottom of the rail, the edges of said receptac'le being permanently secured Within the interlocking portions of the rail; and a fusible closure for the opening.

In testimony whereof I have name to this specification in the two subscribin witnesses.
