1 Claim.

This invention relates to weather strips, and the object is to provide a new and unique weather strip of very simple and inexpensive form that may be secured to a sash or similar structure for spring contact with a companion element as for instance, the frame of a window and which may be applied without necessity of utilizing a fastening means such as nails or screws as has ordinarily been the case and further is adaptable for.

use either with a wood or metal sash.

The commonly known weather stripping in use is usually of such a form and arrangement as to require a considerable amount of metal in comparison to that required in the present invention and further requires to be nailed or otherwise attached by hand to the sash or the frame as the case may be. By my invention the amount of metal utilized is reduced to a minimum and further is adapted to be snapped into place under spring pressure in a groove provided in one of the numbers, and having a portion adapted for yieldable engagement with the companion member thus effecting a saving in both the cost of the material and in the cost of assembly.

Another object of the invention resides in the provision of a weather strip for use with a sliding sash the edge of the sash extending into a groove in the frame, and the weather stripping secured in the edge of the sash and extending toward the groove in the frame whereby the weather stripping is out of sight at all times when the sash is in place.

These and other objects and the several novel features of the invention are hereinafter more 85 fully described and claimed and the preferred form of construction of a metal weather strip embodying my invention is shown in the accompanying drawing in which- Fig. 1 is a section through a metal sash and frame showing the application of my improved weather strip thereto.

Fig. 2 is an enlarged perspective view of my improved weather strip.

Fig. 3 is a section through a wood sash and frame member showing the application of my improved weather strip thereto.

Fig. 4 is a sectional view similar to Fig. 3 showing an alternative form of the weather strip.

In Fig. 1 is shown a cross section of a steel frame and sash members in slidable relationship therewith. In the construction shown, the frame member includes the sash pulleys 1 and 2 supported on the frame 3 and a component part of the frame structure is shown at 4, 5 and 6 which,

below the point of section, are usually united in a single piece and here shown as being separated to provide a slot 7 and 8 for the sash rails 9 and 10 which extend thereinto. These rails 9 and 10 are U shaped in

character having grooves

11 and 12 in their outer edges and on the inner edges are arranged to provide a groove to receive the glass elements 13 and 14. These

grooves

11 and 12 are preferably formed with parallel side walls and are adapted to receive my improved strip by simply forcing a return-bent edge of the strip into the groove not requiring other means of fastening.

The strip consists of a single sheet of metal 15 having a portion 16 at one edge bent to an angle of usually less than ninety degrees with the body, the distance between the outer edge of the bent portion 16 and the body of the strip is nor mally greater than the width of the

groove

11 or 12 in which it is to be seated. Thus, in forcing the strip into the grove the portion 16 is caused to be bent toward the body and thus to force the body to engagement with one wall of the groove with the bent edge 16 lying in contact under pressure with the opposite wall and at such angle as will prevent the ready withdrawal of the strip from the groove. That is, once this bent edge of the strip is forced into the groove, it is very dinicult to Withdraw the same due to the wedging relation of the portion 16 with the wall of the groove engaged by the terminal edge thereof. The opposite edge portion 19 of the strip is preferably rebent upon itself at the terminal edge as indicated at 1'7 and at a distance from the said edge is bent to provide a shoulder or portion 18 that, in the arrangement shown in Fig. 1, is the point of departure of this bent edge portion 19 from the plane of the body 15 and the return-bent terminal edge 17 lies in contact with a portion of the frame members as shown in Fig. 1. This frame member, in addition to having the parts 4, 5 and 6, has a part 20 shaped to provide a wall against which the edge of the member 15 engages while the central part 5 of this section of the frame is likewise shaped as at 21 for engagement by this resilient edge portion of the strip.

There is in the construction shown, a sliding contact of the strip with the stationary portion of the frame, the strip being carried by the sash, but it is obvious that other arrangements of the strip, sash and frame may be utilized without departing from the spirit of the invention, as for instance, the strip may be secured to the stationary member with the resilient portion of the strip engaging the sash rail.

There is a further variation of the invention shown in Fig. 3 more particularly adaptable for usewithwood sash or complemental wooden members between which there is an interstice required to be sealed. In the structure shown in Fig. 3, a sash rail is shown at 25 and a frame at 26 havin a groove 27 formed between a stop member 28 for engaging one side face of the rail and an integral portion of the frame member 29 engaging the opposite side face of the rail in which the rail is slidable. The edge 30 of the sash facing the bottom of the groove or sash way 27 is formed with a longitudinal groove 31 near one of its side faces and the bent edge 16 of the strip is insertible therein to secure wedging and tension engagement in the groove after the manner above described with the metal sash and frame.

A further variation in form of the invention is shown in Fig. 4. In this case a wood sash and frame are utilized as an illustration of one of the uses of the weather strip, the recessed frame member 26 having a sash rail 25 slidable therein in which is provided the groove 31 as in the structure shown in Fig. 3. The strip has the same form of body 15 and downturned end 19 as in the previous structure shown in Figs. 1, 2 and 3 but the groove engaging edge is formed of an outturned edge member 16 connecting with a portion 40 bent relative to the body to lie in engagement with one wall of the groove opposite to that occupied by the portion 41 shown in Fig. 3, the part 16 forming a V in relationship to the part 40 and the part 16' wedging against the wall of the groove due to the said edge 16 being defiected toward the portion 40 by insertion of this edge into the groove.

The functional relationship of the parts of the strip with the

respective members

25 and 26 is identical with that of the strip shown in Fig. 3 but in the structure shown in Fig. 4 the deflection of the body portion or flange 15 toward the grooved face of the rail tends to draw the portion 40 of the strip tightly to engagement with the wall of the groove 31, while in the case shown in Fig. 3 the similar portion 41 of the strip has a tendency to draw the said portion away from its wall by deflection of the body 15. While this makes no material difference in the successful operation of the strip it serves to indicate one of the variations in form of the strip within the scope of the invention as defined by the appended claim.

For this particular type of insulation illustrated in Fig. 3, the body of the strip may be bent as at 32 so that the body 15 of the strip extends at an angle to the face of the sash in which the groove 31 is formed and the terminal edge 19 extends toward the said face with the bent portion 18 thereof lying in spring contact with the bottom of the sash way in the frame and thus sealing the interstice between the two members.

The principal feature of the invention, as will be observed from the foregoing, resides in the formation of one of the edges of the strip for a wedging relationship in the groove to permit this edge of the strip to be forced into the groove to thus place the edge 16 under tension and in a wedging relation with a wall of the groove and the remaining portion shaped or bent to spring contact with the surface of the companion member and while the point of contact is not the same in the two instances of construction shown the structure of the strip is practically identical and of identical function in both cases.

It will be evident from the foregoing that the various objects of the invention are attained by the construction described, and it is further to be understood that various departures may be made by varying the form of the strip in cross section both for engagement with the groove and for yieldable contact with the member companion to the grooved member without departing from the spirit and scope of the invention as set forth in the appended claim.

It will be further evident that since the weather-stripping is secured in the peripheral edge of the sash and extends toward the groove in which the edge of the sash slides that the stripping will be hidden from view when the sash is in place.

Having thus fully described my invention, its utility and mode of operation, what I claim and desire to secure by Letters Patent of the United States isi A metal strip for closing an interstice between a sash and a frame therefor in which the frame is provided with a longitudinally extending opening and. a part thereof providing an inclosure on one side of the opening and the sash provided on its edge facing the frame with a U shaped groove, one leg of which is of greater length than the other and extending through the opening of the frame into the inclosure, said strip being formed of resilient metal having one edge thereof bent longitudinally to lie at an angle to the body and adapted for insertion in the groove whereby the said bent edge is placed under tension to hold the strip in the groove, the remainder of the strip having a body portion lying in contact with the inner face of the longer leg of the U groove and bent at its'terminal edge to lie in yieldable contact with the wall of said inclosure.
