COMBINED WEATHER STRIP AND WINDOW GUIDE Filed Feb. 29. 1936 nucm foz Patented Dec. 28, 1937 UNITED STATES COMBINED WEATHER STRIP AND WINDOW GUIDE Edmond J. Feiler, Madison, Wis. Application February 29, 1936, Serial No.'66,480

2 Glaims.

My present invention, in its broad aspect, has to do with improvements in combined weather strips and window guides and its primary purpose is to provide a weather tight member for use with window sashes and the like, and at the same time balance the same so that sash weights and cords may be eliminated, and at the same time the parting stop between sashes may be eliminated, thus affecting a large saving in costs of material and installation, and at the same time providing a more advantageous, efficient and economical assembly. More particularly, it is my purpose to provide a spring bronze (or other non-corroding spring metal) strip which is designed to be quickly attached to the fame, and which has an outstanding spring part which engages in a groove in the sash to keepout the weather and at the same time balance the sash by frictional resistance against dropping of the sash so that the sash will remain raised when opened without the use of weights, pulleys and cords.

My invention also contemplates the provision of spring metal weather strip members for the bottom, top and check rails so that the entire window construction is rendered weather proof, and in this form a strip is used which is preferably of spring bronze and which is attached along one edge and the free edge providing the spring closure.

Among the many advantages of my invention may be briefly defined the following; first, I eliminate weights, pulleys and cords in balancing a sash; second, I provide in the same structure a very desirable weather stripping which is impervious to both wind and water; third, my device is quickly attachable on standard window and sash construction thereby reducing cost of material and labor; fifth, I use a metal-wood frictional contact which is desirable in this type of construction in balancing a sash, and which may be lubricated, and which compensates for any wear taking place in the meeting surface of woodi. e. the groove in the side rails of the sash; sixth, my device is cheap, efficient and has no parts likely to get out of order, and; seventh,

chattering or vibration of the sash is prevented and the sash will not stick in damp weather nor become loose (through drying) in hot dry Weather.

Other objects and advantages will appear as the description proceeds, but emphasis is laid upon the fact that changes in form, shape, size and arrangement of parts is permissible provided same fall within the purview of what is claimed.

In the drawing wherein is illustrated the preferred form of my invention:-

Figure 4 is a view of the type of my invention adapted to weather proof the meeting surfaces of the top and bottom rails of a sash,

Figure 5 is a view of the type of my invention shown in Figure 4 as applied to the check rails, and the top and bottom rails, same being in cross section,

Figure 6 is a plan View of the type shown in Figures 4 and 5,

Figure 7 is a section of the same applied to the check rails,

Figure 8 is a cross section showing my integral double sash guide in position,

Figure 9 is an edge view of my double ribbed strip designed for use with a double sash, and

Figure 10 is a plan view, partly broken away, of the form of my invention shown in Figure 9.

In the drawing where like characters of reference refer to like or similar parts throughout the several vlews;--

The numeral (I) is the outside casing of a window frame (2) the storm stop, (3) the frame, and (4) and (5) the side rails of the upper and lower sashes, and it will be noted that with my invention the parting stop is eliminated, and preferably the upper and lower sashes are brought closer together. In Figure 4 the top and bottom rails respectively of the lower and'upper sashes are shown, and designated (6), and in Figure 7 the check rail is designated (1) These parts are I conventional and a part of ordinary window construction. It will be noted that the weights, pulleys and cords for balancing the sashes are eliminated.

The side rails of the upper and lower sashes are formed with grooves (8) of sufficient depth to receive and clear the ends of the outstanding ribs of weather and guide strips (9). Each combined weather and guide strip (9) has a concave base (l0), and the outstruck rib member (H) has spaced walls and extends midway the side flanges or feet (l2) lengthwise of the strip. The strips are formed preferably of spring bronze and may be formed integral with a one piece base (l2a) for double sash as shown in Figure 8, and A--B in Figure 9, and concave base (10) and the walls of the rib (I I) have considerable fgive so that the pressure against the side rails and against the walls of the grooves (8) is sufiicient to balance the sash and eliminate the necessity of using sash weights, pulleys and cords. Any wear in the groove will be taken up by expansion of the rib to compensate therefore, and the strip also has suificient give to compensate for swelling and shrinking of the sash in various kinds of weather. The meeting surfaces of the ribs and grooves may be lubricated when installed or at any time deemed desirable to do so. The strips are attached by, screws or nails through the flanges or feet (I2) and without the use of special tools.

As shown in Figures 4, 5, 6 and 7 a type of my invention having a spring bronze construction and an attaching flange (l3) along one edge is adapted for use with the top, bottom and-check rails, in which case the free part of the strip, designated (I 4) is concave and stands outto press against the surface of the adjacent sash to form a weather tight closure. The free ends in this form, designated (l5) are slightly turned out.

In applying my combined guide and weather strip the parting stop is eliminated and also the sash weights, cords and pulleys, and the weather 7 strips are merely screwed or nailed into place and the sashes placed with the grooved side rails engaging the ribs. Some lubrication may be used if desirable.

Changes in shape, size, form, arrangement and material may be made to meet diiferent requirements of practice as with different sizes and types of sashes, but such changes are permissible provided they fall within the scope of what is claimed.

.1 claim:-

1. A combined window sash guide and weather strip comprising an'elongated metal body having foot portions at its side edges for attachment to a window frame to hold the strip in place, a

longitudinal medial rib formed on the body and having a relatively narrow top and sides flaring outwardly from the top toward the bottom of the strip, said rib adapted to be' received in a groove of a window with the outwardly flaring side portions frictionally contacting the edges of the groove to seal the same and frictionally resist movement of thewindow, and similarly. formed and shaped upwardly curved web portions between the foot portions and the medial rib and integral therewith and frictionally contacting the side edges of a Window only at the point where the web portions meet the base of the medial rib and designed to contribute to maintainance of a tight closure and frictional support of the window.

2. A combined window sash guide and weather stripcomprising an elongated metal body having spaced foot portions lying flat in the same plane for attachment to ,a Window frameto hold the strip in place, a longitudinal medial rib between the foot portions and connected therewith by web portions. integral with both the rib and the foot portions, the rib formed with a relatively narrow curved topand sides flaring outwardly and downwardly 'iri'opposite directions toward the web thereby to frictionally contact the edges of a groove in a window to seal the same and frictionally resist movement of the window, and the web portions curving upwardly from the foot portions to the sides of the rib to contact the window only at the point Where the 'web portions meet the base of the rib to contributeto maintenance of a tight closure and 'frictionallysupport the window.
