SPECIFICATION forming part of Letters Patent No. 539,975, dated May 28, 1895.

Application filed March 16, 1895 Serial No. 542,005. (No model.)

to the letters of reference marked thereon,

forming part of this specification.

My invention consists in the improvement in windows for locomotive cabs and other structures, hereinafter set forth and explained and illustrated in the accompanying drawembodying my improved Windows.

ings, in which- Figure 1 is aside viewof a locomotivecab Fig. 2 is a vertical section of the same on the line 1 l in Fig. 1, looking in the direction of the arrow. Fig. 3 is a detail view on the line a: 00 in Fig. 1, showing a section of my improved window.

r The object of my invention is to construct awindow for locomotive cabs and other structures, so that at all times it will be free from any accumulations of frost ordampness,

. which will in any wise obstruct or intercept window.

In previous instances double windowshave the view of a been used, the space between the two glasses being filled with water or other transparent fluid, heated by means of steam pipes or other heating mechanis'm connected therewith for that purpose, or filled with a transparent noncongealable fluid, such as alcohol or benzine.

I construct my improved Window with double glass, and between the edges of the glass I place a packing of some absorbent material, by means whereof the dampness in the air contained'between the two glassesis speedily absorbed, so that it becomes abnormally dry, and is retained in that state, thereby effectually preventing the accumulation of any frost or-dampness upon either the outside or person looking through such inside panes of glass, so that at all times the 'placea strip of highly absorbent material-for example a folded strip F' of prepared felt packing, so that the inner edges f thereof overlap the edge of the outside glass E; and upon these folded edges f of the packing I place the inner glass G, so that the edgesfof this packing keep the two glasses E and G a short distance apart, and form a semiair tight packing around the edges of said glass. The larger part of this packing forms a fold) and projects beyond the edges ofthe glass and substantially fills the groove d of the frame; To the inside of the frameD Isecure :astop H by means of screws h, the inneredge a of which stop projects over upon the edge of the inner glass G, and clamps it down upon the edgefo'f'the packing F, so as to hold the glasses G and E firmly in place in the frame D. In the stop H, directly over the fold f of act upon'the packing to dry any moisture out I of the packing which it may absorb from the air inclosed between the glasses E and G.

Having thus fully described my invention, so as to enable others to construct and use the same, What I claim as new, and desire to secore by Letters Patent of the United States, is-
