ADOLPH SOLEIVI, OF DULUTH, MINNESOTA, ASSIGNOR OF ONE-HALF TO LUDVIK SOLEM.

METAL WEATHER-STRIP.

Specification of Letters Patent.

Patented Mar. 2'7, 191?.

Continuation in part of application Serial lilo. 830,994, filed April 10, 1914. This application filed July 15,

To all whom it may concern:

Be it known that I, AooLrrI SOLEM, a citizen of the United States, residing at Duluth, in the county of St. Louis and State of Minnesota, have invented new and useful Improvements in Metal l Veather-Strips, of which the following is a specification.

My invention relates to a metal weather strip and has as its principal object the provision of an appliance for the exclusion of wind, draft, dust and smoke through windows or between window sashes and frames.

A second object of my invention is to provide means for making window sashes operate up and down easily and smoothly in their allotted sash ways or grooves in the window frame.

A third object of my invention is to provide means for always holding the window sash perpendicular or parallel with the sides of the .window frame.

A'fourth object of my invention is to pro vide means for keeping the window from ,rattling or shaking when the same is subjected to wind or other disturbances.

A fifth object of my invention is to provide a metal window strip which shall so cooperate with the sides of the sash that the sides may be removed or replaced when desired without removing-the weather strip or destroying the same.

In the accompanying drawings Figure 1 is a cross sectional view of the sides of a window frame with the usual stops or bead strip and the side stiles of the window sash, the metal strip being applied thereto according to my invention.

Fig. 2 shows a perspective view of the weather strip shown in Fig. 1.

Fig. 3 is a horizontal sectional view show ing a slightly different arrangement of the weather strip and also showing a strip of slightly different proportions.

Fig. 3 of this application is identical with Fig. 4 of my copending application No. 830,994, filed April 10, 1914.

Referring more specifically to the drawings, 1 is the side or jamb of the window frame. 2 designates the stiles of the two sashes and 3-3 are the window panes. 4t designates the blind, partings and inside stops or beads which create the sash-ways or grooves in which the window stiles 2 slide up and down. 77 designates as a whole the weather strips as shown in Figs.

Serial No. 10,002.

1 and 2. The metal strips such as 7 are all of one piece of metal cut to the desired shape, and include a relatively short portion 11 which extends at right angles to the wind w frame 1 parallel to the plane of the 6 sash. Adjoining the portion 11 is a portion 8 which extends at right angles and runs along the inner face of the window frame between the frame and the vertical edge of the sash. The strip then bends at right angle to the portion 8 running alongside the blind or parting stop as the case may be to a point 10 where it bends again at right angles extending thence perpendicularly to the plane of the sash into a rabbet 5, the rabbet 5 being of a general L shape as shown, the inner end of the rabbet being rounded out on the side toward the window frame. The inner point 9 of the strip reaches almost to the inner end of the rabbet 5, although I prefer to leave a small clearance between the strip and the sash at this point so that the sash may run easily. From the point 9 the strip is doubled upon itself on the side toward the frame and extends back to the point 10, from which point it is bent at right angles toward the frame. It will be seen that the strip at the point 9 bulges out into the rounded out portion of the rabbet 5 on the side toward the frame; that the sash will catch the inner rounded end of the strip whether the window is pushed back and forth in a direction perpendicular to the frame of the sash or in a direction parallel thereto, and that the window will be prevented from rattling.

Moreover, the sash extends into the sash wav 12 provided by he strip so that it provides an effective shield for wind, dust or smoke when the window may have shrunk or expanded as a result of atmospheric changes, since one part of the strip is always securely hooked into the window frame.

It will, moreover, positively guide the sash parallel with the sides of the window frame although the sash itself may shrink away from the frame, since the sash-way 12 is surrounded on three sides by the metal of the strip and this last sash way will follow the window, whether it contracts or expands,

on hinges or hangers such as storm sash, cel- 11o moved or replaced without removing the weather strip or destroying the same. 7

Referring more particularly to Fig. 3,

the sash 15 are both shown in position where the rabbet 14; extends inwardly from the 7 central parting strip or bead. Moreover, the

inner end of the strip 12 where it extends into the rabbet 14 and is folded back on itself is curved outwardly so as to leave a space 18 which is of suffieient dimensions so that the strip is installed to contact with the inner rounded out portion of the rabbet 14 at this point. The strip 12 is also slightly shorter than the strip 7 as will be plainly seen.

Having thus described my invention I claim 1. The combination with a window frame and a sash therein .of a vertical bead strip projecting at right angles to the frame alongside the sash, said sash having a recess opening only against said strip, said recess extending inwardly from its point of openmg and also toward the frame, and a metal weather strip fastened to the frame and extending across the edge of the sash, between the sash and first mentioned strip, and into said recess, the weather strip being doubled back outward toward the frame within said recess and having a rounded portion extending into the portion of said recess which extends toward the frame whereby adj ustable movement of said sash in any direction is permitted.

2. As an article of manufacture a metal weather strip having a relatively long side adapted to sit between the window frame and the vertical edge of the sash, a portion extending at right angles to said first mentioned portion, a portion extending at right angles to said second mentioned portion, and a doubled back portion lying between said first mentioned and said third mentioned portion forming a rounded projection extending toward said first mentioned portion whereby a sash-way is provided surrounded on three sides by metal and having a restricted mouth.

8. The combination with a window frame and a sash therein of a vertical bead strip projecting at right angles to the frame along side the sash, said sash having a recess opening on the side toward said strip, said recess extending inwardly from its point of opening and also extending from the point of opening toward the frame, and a metal weather strip between said sash and bead strip and extending into said recess, said weather strip being doubled back toward the frame within said recess and having a laterally extending rounded portion extending into the portion of said recess which extends toward the frame from the point of,
