tntrd Semilla wi @llllw S. KEPNER, OF PO'ITSTOWN, PENNSYLVANIA.
Lette/rs Patent No. 92,841, dated July 20, 1869.
IMPRovI-:D WINDOW-SASH.
The Schedule referred to in these Lettere Patent and making pa'rt of the s'ame.
A l Figurel. remeseuts afnult elevation cfmy improved window-frame and self-balanced shaft, and
Figure 2, a vertical crosssection of the same, on the line x x of iig. 1.
Letters of like name and kind refer to like parts in each of the ligures.-
In ventilating a room in' winter, where self-balanced sash are used, much difliculty has, been experienced in so arranging them as to permit the upper sash to be dropped without correspondingly raising the lower sash; and of the many devices used for the purpose of' overcoming this dificulty,'non`e have been free from serious objections, such as complication of parts, increased cost, Ste.
'Io removethese objections is the design of my invention, which consists in increasing the height ol' the casing or bead-strip upon the inner side of the sill, as will hereinafter be fully set forth.
In the annexed drawing- A A represent the sides, B the sill, and C the top of the windo\\'iiame, of usual construction.
Sliding vertically withinsaid frame are two sash, D D', of ordinary form, which comlterbalance each other, by means of cords, dd, secured to the upper right and left-hand corners o f each, and passing over pulleys Il E, suitably pivoted upon the inside of the frame, near its top, the length Ofsaid cords being such as to just close the upper sash, when the lower sash is shut down upon the sill.
lf desired, the sash may be connected by means of a single cord, secured to the top rail, midway between its ends.
It will be evident that when thus suspended, if one sash is moved, a corresponding opposite motion will be imparted to the other sash,rso that it will be impossible to lower the upper sash for the purpose of ventilation without in the same degree raising the lower sash, and admitting a draught of air.
To obviate this ditculty, I increase the height of the casing .or ,bead-istripE upon the sill, as muchas it isldesire'd to lower the upper sash, usually about two inches, which allows the lower sash to be raised to a height equal to such increase, and the upper sash correspondingly lowered, without producing an opening below said sash, by which means the heated Aand impure air is allowed to escape om the room,
Without the admission of a current of cold air, from the lower part of the window.
This arrangement -electually removes all objections to this manner of suspending sash, and is especially applicable to the windows of sleeping-rooms, where ventilation is desired without a draught of cold air, with its injurious and often fatal results, and, from its cheapness, its general adoption is deemed certain.
Having thus fully set forth the nature and merits of iny'invention,
What I claim as new, and desire to secure by Letters Patent, is-
'Ihe casing or beading-strip F, when raised or increased in height, as shown, in combination with the self-balanced sash D and D-,'substan.tially as and for the purpose specified.
In testimony that I claim the foregoing, I have herel unto set my'hand, this'24th Aday of yMay, 41869.
` S. KEPNER.
