MODE 0F HANGING WINDOW-SASH.

Specification of Letters Patent No. 15,447, dated July 29', 1856.

To all whom it may concern:

Be it known that I, CROMWELL P. WEAVER, of the city of Philadelphia and State of Pennsylvania, have invented a new and Im proved Mode of Hanging Vindow-Sashes; and I do hereby declare the following is a full, clear, and eXact description of the same, reference being had to the accompanying drawing and to the letters of reference marked thereon.

My invention consists in so connecting window sashes to bars arranged to slide in.

recesses in the j ambs of the window frame, that the said sashes may be removed and replaced with facility. f

In order to enable others skilled in the art to make and use my invention I will now proceed to describe its construction and operation.

On reference to the drawing which forms a part of this specification Figure l, is an elevation (looking from the inside of a window frame, with sashes hung in my improved mode; Fig. 2, the same as Fig. l, with part of the frame removed; Fig. 3, a side view in section on the line 1-2 Fig. 2; Fig. 4, a transverse sectional plan, of part of the frame the sashes being both up; Fig. 5, a top view of part of the frame and sashes, with the lintel removed; Fig. 6, a perspective view of the sliding bar for one sash and Fig. 7 a perspective view of the sliding bar for the other sash. Figs. 4:, 5, 6, and 7 are drawn to an enlarged scale.

The same letters of reference allude to similar parts throughout the several views.

The frame of the window consists of the lintel A the two hollow j ambs B, B, and the sill C. The side pieces b and b of the jambs project beyond the cross piece c so as to form a recess for receiving the sliding bars D and E which together lit accurately, but so as to move freely, therein.

On each of the sliding bars D is a projecting strip d one end of which lits with a shoulder against the side b of the j amb, the other end forming a lip against which rests the side of the sash F. On the top of each of the sliding bars D is secured a light metal lip e which projects a slight distance over the top of the sash F when the latter is in its place, it has also a metal strip f at the bottom, and on this rests the bottom of the sash.

Each of the sliding bars E has a projecting strip zagainst which bears the sash Gr it has also on the top a light metal lip i which projects over the top of the said sash when the latter is in its place, and also a metal strip on which the sash rests.

On the bottom bar of the sash F (see Fig. 3) is a projection Z against which bears the sash G, and the latter has a similar projection la at thetop bearing against the sash F. The bottom sash G has a spring latch m on each sidethe point of which ts an orifice in the flange of the metal strip j on thebottom of the sliding bar E from which the latches can be withdrawn and replaced at pleasure. Each of the sliding bars E hasa tongue n which fits in a groove in the cross piece e of the hollow j amb.

Each of the sliding bars D has a projecting bracket p to which one end of the cord R is connected., This cord passes upward and over a pulley T then downward and around the pulley SY then upward and over the pulley I-I then downward ,again until it reaches a projection o on the sliding bar E to which projection the cord is attached. The pulleys H and T run loose on pins attached to a plate which is secured permanently to the cross-pieces c of the hollow jambs, and the pulley S is hung on a pin in a staple projecting from the counter-bal ance weight I.

The sliding bars D and E being placed in the recesses formed on the inside of the jambs, and the cords connected to the same as described, the two bars are first slid up to the top as seen in Fig. 3, the sash F is then put into its place by inclining it so as to catch the metal strips e e it is then easily pushed home so that the bottom of the sash rests on the strip f; the sash G is now connected to the sliding bars F in a similar manner, and the points of the spring latches m allowed to catch into the holes in the strip j.
