THOMAS E. WALKER, OF DETROIT, MICHIGAN, ASSIGNOR TO CRITTALL CASEMENT WINDOW COMPANY, OF DETROIT, MICHIGAN, A CORPORATION OF MICHIGAN.

WEATHER STRIP FOB, WINDOWS.

Application filed December 3, 1924. Serial No. 753,536.

To all whom it may concem:

Be it known that I, THOMAS E. WALKER, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Weather Strips for Windows, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to weather strips for windows, and more particularly window framesand sashes made of metal, although the weather strips are applicable to frames and sashes made of wood.

My invention aims to provide weather strips that may be easily and quickly mounted m a window frame to insure a perfect fitting of sashes in the frame, so that there will not be any cracks, spaces and loose connections permitting air and the elements to pass through the frame and interfere with the frame and. itssashes as a closure. The

weather strips are arranged in the frame to form channel guides for the sashes and anintimate relation between the sashes and the frame, without interfering with an easy adjustment of the window sashes. Weather strips may also be used on the sill and lintel of the window frame to ensure proper connection of the sashes with the frame when the sashes are closed.

' It is a well known fact that metal sashes cannot be at all times maintained weather tight in a metal frame, particularly if such frame and sashes are of a comparativel low grade. It is in connection with suci frames and sashes that my weather strips may be readily installed to compensate for any poor fitting, andprovision' is made for producing a constant pressure on some of said strips so that the other stri s are brought into cooperative relation wlth the pressure strips to ensure a thorough backing of the sashes within the window frame.

My invention further aims to provide a simple, durable and inexpensive window construction thatwill be hereinafter-specifically described and thenclaimed.

Reference will now be had to the drawings, wherein k I Figure 1 is a front elevation of a window frameembody-ing features of my invention;

Fig. 2 is'an enlarged vertical cross secnovel means is employed for establishing tional view of the same with intermediate parts of the frame broken away;

Fig. 3 is an enlarged horizontal sectional view of a portion of the window frame, and

Fig. 4 is an enlarged elevation of the inner Wall of a stile with a mid rail partly in section.

Reference will first be had to one of the stiles of a window frame, which is best shown in Fig. 3 as being composed of two 2 bars 1 and 2 having flanges 3 and mid rail flanges 4. The flanges 3 are adapted to form the inner and outer side walls of the window frame and attached to said the edges 8 of the angle bars 6 forming a mid rail on the stile. The angle bars 6 are preferably made of material lighter in weight than the 2 bars 1 and 2 and said angle bars are adapted to cooperate with the bars 1 and 21in forming wells 9- for weights or other devices that may be utilized to facilitate adjustment of sashes in the window frame.

Suitably attached to the 2 bars 1 and 2, in parallel with the mid rail, are retaining strips 10 which cooperate with the mid rail in providing parallel sash ways 11. In each sash way 11 is a set of weather strips which are. shiftable iii" a lateral direction with the weather strips of each se cooperating in fol-min a channel guide 12 for the side rail 13 0t the sash 14. Y

The outer weather strips are designated 15 and the inner strips are designated 16, the former being angular in cross section, and the latter substantially Z shaped. The strips of each set are arranged in overlapping relation on eachZ bar 1 or 2 and are slotted, as at 17 so that screws 18 or the like may be attached to the 2 bars 1 and 2 for slidably holding the weather strips for flanges by rivets 5 or other fastening means a against the rails 13 of the sashes and cause said rails to crowd the outer weather strips- 15 against the retaining rails 10. In consequence of this arrangement the inner and outer weather strips will cooperate in packing the sashes relative to the frame stile and since the inner weather strips 16 overlap on the mid rail there will be a comparatively air tight connection between the sashes and the window frame.

The mid rail at suitable intervals is provided with rivets 21 or other fastening when exposed to the elements.

Practically the same manner of packing the side rails of the, sashes14 may be utilized in packing a sash top rail 22 relative to a lintel 23, and the sash bottom rail 24 relative to a sill 25. The lintel and sill are of suitable structural'shapes and are preferably formed with pressed out hollow beads or strips 30 apertured at intervals for transversely arranged colled expansion springs 26 which have the end convolutions thereof bearing against angle weather strips 27 placed in overlapped relation on each head or strip 30 and retained thereon by screws 29 or the like. The weather strips 27 are slidable laterally on the beads or strips 30 and are preferably provided with inclined side walls for snugly engaging in the channel top and bottom rails ofthe sashes, as best shown in Fig. 2. The weather strips 27 will be distended against the rails of the sashes and afford. a sealed connection when the sashes are closed, and when either sash is open the weather strips cannot become displaced because of the screws 29, and it is obviousthat the springs 26 will be housed during an open condition of the sash.

It is believed that the utility of my weather strips willbe apparent without further description, and while in the drawings there is illustrated a preferred embodiment of my invention, it is to be understood that the structural elements are susceptible to such variations and modifications as fall within the scope of the appended claims.

What I claim is s .1. In a window framehaving a sashway, a sash slidable in the frame sashway, said sash having channel "rails, weather strips in the frame sashway forming guides for said. sash, and weather strip holding means carried by said frame and extending into said channel rails.

2. In a window frame having a sashway,

a sash slidable in the frame sashway and opposed weather strips slidably connected to the window frame, said opposed weather strips forming guides for said sash.

3. In a window frame having a sashway, a sash slidable in the frame sashway, and weather strips in overlapped relation in the frame sashway and supported therein for lateral movement and to form guides for said sash.

4. In a window frame, a rail,a retaining strip, a sash slidable between said rail and strip, a non-resilient bodily shiftable weather strip between said rail and sash, a nonresilient bodily shiftable weather strip between said sash and retaining strip, and means located in said rail, operatable against one weather strip to cause said sash to shift the other weather strip.

5. In a window frame, a rail, a retaining strip, a sash slidable between said rail and strip, a weather strip between said rail and sash, a weather strip between said sash and retaining strip, said weather strips being in overlapped relation andsupported for lateral movement .by said frame, and means operatable against one weather strip to cause said sash to shift the other weather strip.
