IMPRCVEMENT IN CAST-IRON WINDOW-SASH-ES.

Specification forming part of Letters Patent No. 15 l, 897, dated June 9, 1874 application liled March 11, 1874.

To all whom it may concern:

Be it `known that I, STEPHEN JONES MEEKER, of Newark, in the county of Essex and in the State of New Jersey, have invented certain new and useful Improvements in Cast-Iron Window-Sashes and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, forming a part of this specification.

Figure l is an elevation, the outer or mainV frame being of wood. Fig. 2 is a vertical section ofthe same. Fig. 3 is a vert-ical section, showing the entire sash of iron. Fig. 4 is an velevation of a horizontal mullion. Fig. 5 is a cross-section ofthe saine. Fig. 6 is a crosss'ection of the cast-iron Inain frame.

My invention relates to the construction of window-sashes out of malleable cast-iron 5 and consists in making it in several parts, one of which is a hollow cross-niullion, secured together by horizontal bolts and by rivets.

Heretofore rolled iron has generally been used for iron sashes for Ere-proof buildings, jails, orl asylums. The cost of' iron in this form, in consequence of labor, is so high as to restrict its use.

In my invention I use malleable cast-iron, casting the several portions of the frame, such as the meeting-rail, side and bottom strips, and horizontal and vertical division-strips or mullions, in separate pieces, so that they may be readily cast and tempered or annealed.

The main frame A may be made either of iron or wood. When made of Wood, as shown in Figs. 1 and 2, the four pieces A, which f compose it, are put together in the usual way,

and secured at the corners. rlhe outer molding-strips B are each cast in one piece, and made malleable, and fitted and riveted together at their corners, as shown at X. The

vertical division-strips or Inullions C are also cast separately, annealed, and :fitted in place between the top and bottom rails, to which they *are secured by rivets, as at Y. The horizontal division-strips or mullions D are cast, made malleable, and tted in a similar manner, but are of short lengths-only the Width of each panedand are cored out so as to be hollow for an iron bolt to pass through, and by means of a screw-nut to clamp the parts together. E is an iron bolt passing through the side strips B and mullions D. A nut, a, on end of this bolt serves to clamp the parts together. The various parts, B C D E, thus riveted and screw-bolted together, are then placed within the window-frame A, and secured thereto by screws Z.- The sash is then ready for the glass.

When the main frame A is made of iron, (common gray iron will answer a good purpose,) it is cast in four pieces, having a 1 1 cross-section, and riveted at the corners, as shown in Fig. 6, having the inner edge cast with a molding or in Inullion form, as shown at m in said figure. The strips C are then put in place and riveted. The strips or lnullions D are then putin place, and the bolt E passed through them, and through strips C and framestrips A, and drawn up tight by nuts Z. The sash is then ready to be glazed.

What I claim as new, and desire to secure by Letters Patent, is-

1. The hollow cross-mullions D, in combination With bolt E, when constructed Vand operating substantially in the manner and for the purposes set forth.

2. The combination of the parts B C D with frame A by means of bolt E and rivets, sub stantially as and for the purposes set forth.

In testimony thatI claim the above-described invention I have hereunto signed myname this 21st day of February, 187 4.

STEPHEN J. MEEKER.
