METALLIC FIREPROOF WINDOW.

SPECIFICATION forming part of Letters Patent N 0. 788,878, dated. May 2, 1905.

Application filed December 26, 1903. Serial No. 186,661.

vT0 all whom it may concern:

Be it known that I, Jonn BOGENBERGER, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented a new and useful Improvement in Metallic Fireproof Vindows, of which the following is a description, reference being bad to the accompanying drawings, which are a part of this specification.

My invention relates to certain new and use ful improvements in metallic fireproof windows, and more particularly to that type of window in which a swinging sash is employed. The object of this invention is to produce a tubular sheet-metal frame thoroughly braced throughout and capable of making practical weather'tight connections, with its swinging sash.

A further object of this invention is to employ an improved form of pivotal connection for a swinging window, permitting the window to be readily adjusted with relation to its pivotal bearing and enabling it to be quickly and easily removed from its mounting.

With the above and other objects in view the invention consists of the devices and parts or their equivalents, as hereinafter set forth.

Referring to the accompanying drawings, in which like characters of reference indicate the same parts in the several views, Figure 1 is a vertical section of a window embodying my invention. Fig. 2 is a horizontal section of one side thereof, taken on the line 2 2 of Fig. 1 above the pivot. Fig. '3 is a similar view on the line 3 3 of Fig. 1, taken through the pivotal connection. Fig. 4 is a vertical section through one of the pivotal bearings. Fig. 5 is an end elevation of the pivot-pin,

' and Fig. 6 is a horizontal section of one side of the window on the line 6 6 of Fig. 1.

In the drawings the window-frame is shown as comprising vertical side casings 8, the top casing 9, and the sill 10, all being made of sheet metal bent in tubular'form. The side a deep central crease, in which is seated a core-plate 15, extending across the tubularstructure and riveted to the shell at the sashbearing 11. The core-plate 1.5 is also riveted in the crease of the back plate 14:, and thus ties the shell and back plate together, besides bracing and strengthening the tubular structure. The crease of the back plate stands out therefrom as a flange to firmly anchor the frame in the surrounding brickwork or masonry.

The top casing 9 is formed of. a single piece of sheet metal bent to form a tubular body riveted together, with the shoulder 13' and a sash-stop 16, having the inclined bearing-surface and the depending outer bent flange 17,

in the crease of which is seated a core-plate 18, which extends across the tubular top easing and is riveted to the top thereof.

The sill 10 is bent up from a single piece of sheet metal, with inclined top and bottom surfaces and an upwardly extending glass seat 19, with an inner bent-over flange 20, holding in its crease a core-plate 21, which is riveted to the bottom of the sill.

A cross-rail 22 extends across the frame from one side casing to the other and is tubular, being bent to form the glass-seat 23, with the shoulder 2a on the inner side thereof, and the inclined upper sash-stop surface with the upwardly-projecting inner flange 25.

A flanged U-shaped strip of metal 26 is mounted on the sash-bearings 11 between the sill 10 and the cross-rail 22 and is bent at its middle portion to form a pair of parallel glassholding flanges 27 and has its side edges bent around and bolted or riveted to the shoulders 12 and 13, respectively.

A window-light 28, preferably of wire-glass, is mounted on the glass- seats 19 and 23 against flange 20 and shoulder 24 and between flanges 27 and is held in place by cleats 29, which are strips of sheet metal bent double at the middle portion, with their side edges bent away from each other to form a T shape in crosssection, the one edge being placed between the edge of the glass and the glass-seat and the other edge bent slightly out of alinement with the first named edge to bear tightly against the glass-seat.

A swinging window-sash is fitted in the upper part of the window-casing and comprises a tubular frame having side stiles formed of U-shaped shells 30, with glass-grooves 31 at their bends and their edges turned inwardly and folded back upon themselves to form slipoints, with the outwardly-turned edges of a bearing-plate 32 and top and bottom rails bent to form glass-seats 33, with shoulders 34 on one side thereof. The outer bearing-surfaces of the top and bottom rails are inclined to fit the inclined sash- stops 16 and 22, respectively, and the top rail is provided with a weatherflange 35 at its inner edge to fit against the shoulder 13, while the bottom rail is provided with a weather-flange 35 at its outer edge to fit against the outer side of the cross-rail 22. Window-lights 28 are also seated in the glassseats 33 and grooves 31 by means of cleats 29 1D the usual manner by employing a mullion 36 of ordinary construction.

The swinging sash is mounted on pivots in the following manner: An angular bracketplate 37, having in its bracket or outstanding member a vertical slot 38, is secured at its other member to the inner face ofeach of the side stiles of the sash by screws 39 threading nto a back plate 40, which is fastened within the stiles by bolts 41. Likewise a socketplate 42 is secured to the face of each side caslng'by screws 43 threading into a back plate 44, which is fastened within said casing by bolts 45, and at its middle portion the socketplate is enlarged, forming a boss which is drilled to produce a socket 46. A pivot-pin 47 has at its medial portion a pair of oppositely-projecting arms 48, which may easily pass through the slot 38 to enable the rounded end of the pivot-pin being seated in the socket 46; but when the pivot-pin is turned a quarter-turn the arms bear against the side of the angular plate 37, so that a nut 49 when turned on the threaded inner end of the pivotpin rigidly clamps said pin to the bracket member of plate 37. It is possible with this construction to adjust the sash in its frame until the desired fit is secured at all parts and then clamp the pivot-pins to maintain that relation.

The slip-joints between the shells 30 and the bearing-plates 32'of the sash-stiles form projecting outer flanges 50 and inner flanges 51 on each side of the sash, said flanges being split at the pivot parts. Above the pivots the outer flange 50 is bent back against the bearing-plate 32 and the inner flange 51 bears against the shoulder 13, while below the pivots the outer flange 5O bears against the shoulder 12 and the inner flange 51 is bent back against the bearing-plate 32, so that when the sash is in its closed position these flanges produce, with the shoulders 12 and 13, weathertight joints the full length of the sash, and the arrangement is such that the swinging of the sash is not interfered with. At the ends of the sash the inclined sash-bearings and the flanges 17, 25,'and 35 complete the weathertight connections. Whenever further adjustment of the sash becomes necessary, it may be readily accomplished by loosening the nuts 49 and adjusting the sash to the desired position and then clamping the nuts again in their new positions on the slotted angle-plates 37. WVhen the sash is desired to be removed, the pivotpins 47 are turned while the nuts 49 are loose, so that the arms 48 may be drawn through the slots 38, when thesash is free to be withdrawn.

From the foregoing it is apparent that a window made in accordance with my invention will be thoroughly fireproof and when the upper sash is closed the entire structure is perfectly weather-tight.
