To all whom it may concern:

Be it known that I, DANIEL HOYT, a citizen of the United States, residing at East Orange, county of Essex, State of New J ersey, have invented certain new and useful Improvements in Weather-Stripping; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to weather stripping means for windows generally, but more particularly for car windows of steel cars.

Heretofore, in car window sashes made either of wood or metal, the sash has been made so as to work freely in the guideways in order to allow for raising and lowering with facility, and also swelling or shrinking of the sash or guideways, the lack of uniformity in materials used and defects in workmanship, all had to be taken into con sideration. It is of course necessary that the sash should not rattle and that it should be so equipped with weather stripping or analogous means as to exclude dust and air. Diflerent kinds of locks and springs have been used to hold the sash firmly in the sash frame, and various kinds of weather stripping have been employed to assist in excluding dust and air.

One of the objects of the present invention is to equip the sash with weather stripping when the parts of the window frame are made of metal, care being taken that the sash will fit snugly within the window frame even where there is considerable variation in the size of sash.

Another object of my improvement is to equip the edges of the sash with felt, or like material, in such manner as to obviate the necessity of employing any special contrivances to cause the sash to fit snugly within the frame.

Another object is to make a weather strip of felt, or like material, having a rigid, flat body portion adapted to be secured to the flat edgesof a sash, and guides to guide the edges of the felt in any direction to contact any desired adjacent surface.

A further object of my improvement is to do away with the necessity of any weather stripping appliances except in direct connection with the sash itself.

It will be understood that felt, or material of like character, has no special rigidity of itself and wherever it is desired that it shall contact it must be carried closely adjacent the contact surface by some auxiliary means. Further, as this material is soft, spongy and pliable, it is preferable that it has a means of holding and securing' itto a window sash such as a metallic container or housing.

In describing my invention, I have hereinafter made use of the word felt but I wish it tobe understood that I use the term simply for the sake of briefness and clearness in description, since any suitable material of a soft spongy nature may answer the purpose, and I, therefore, do not wish to confine myself to felt as a material in connection with my invention.

In the accompanyin drawing Figure 1 is an inside elevation o a car window sash as it appears when fully equipped with my novel weather stripping-Fig. 2 is an enlarged cross sectional view, taken on the lines 2-2 of Fig. 1-Fig. 3 is an enlarged cross sectional view'taken on the lines 3-3 of Fig. l-Fig. 4: is a detail perspective view of my improved weather stripping in the form such as I prefer to utilize for the side edges of a window-Fig. 5 is a detail perspective view of my improved weather stripping in the form such as is utilized in instances like that shown at Fig. 3, and Figs. 6 to 13 inclusive are detail sectional elevations showing modified forms of my improved weather stripping.

Similar numerals of reference denote like parts in the several figures of the drawing.

1 indicates the side posts of the window frame, 2 the inside sash stops, 3 the outside sash stops, and 4 the movable sash, such as are employed in steel car constructions.

The improved form of weather strip whichI preferably use for the side edges of the sash is shown in Figs. 2 and 4, in which 6 indicates in cross sectional view a flat metal strip which extends the entire length of the sash and is formed with a flange or guide 8 at one side, and for convenience I will designate this strip as the guide strip. On this guide strip I place a strip of heavy felt 5 wider than the guide strip, and on this strip offelt I place another metal strip 7 of the same length as the guide strip but spaced from the flange 8. A strong pressure is then placed on the strip 7 to clamp the felt tightly to the guide strip, and the three strips 5, 6, and 7 are then securely riveted together, making a complete weather strip ready to secure to the fiat side edges of the sash. When the strip of felt 5 is compressed between the strips 6 and 7 one edge of the felt is turned at right angles to the strip 7 being guided in this direction by the flange 8 of the guide strip, and I have designated this angular projecting portion of the felt by the numeral 5. The opposite side of the guide strip having no angular portions, the edge 5 of the felt projecting therefrom extends horizontally from the guide strip. The weather strip thus constructed is secured to both side edges of the sash-4,-preferably with screws, the guiding flange 8 being flush with the outside surface of the sash; the sash is then inserted in the window frame between the posts 1, 1, with thelsash stops 2, 2, removed.

The projecting felt portion 5 being compressed between the sash and each sash post causes the felt to mold itself in the sash guideways, maintaining the sash firmly between the posts, with a resilient, dust-proof weather strip extending the entire length of the sash. By having the felt edge 5 turned at right angles to a cross section of the sash, the latter is allowed to be pressed tightly against the outside stops 3. After the sash has been placed in position in the window frame the inside stops 2 are secured in place.

It will be noted, by referring to Fig. 2, that the felt edge 5 extends considerably beyond the inner face of the sash, and that in securing the inside stops in position this felt edge 5* will be compressed to a considerable degree, which presses the sash firmly against the outside stops 3 and thus prevents lateral movement of the sash as well as rattling, and afl'ords an extra precaution against all dust entering the car. It will be noted that between the felt edge 5 and the felt edge 5 there is an air chamber 9 which latter materially assists in drying out the felt if for any reason it becomes wet. There is resiliency enough in the felt to care for any swelling or shrinking that may occur either in the sash or frame, and also allow for any inequalities in materials which compose the sash or frame, and the sash may be raised readily and smoothly.

Window sills for cars are generally formed on a bevel or pitch, of about twenty degrees to thirty degrees, and the bottom edges of sashes are beveled to correspond to the bevel of the window sills. I make my weather stripping for the bottom of the sash on the same principle and apply it in the same manner, as in the instance of the side edges of the sash, but there are slight variations in order to allow for the shape of the bottom edge of the sash, without the necessity of cutting, fitting or grooving of the sash. The. flat body of the guide strip 6 has, in this instance, two guiding flanges, one formed at an acute angle to the body portion and denoted by the numeral 12, and the other formed at an obtuse angle to the body portion and denoted by the numeral 13. so that when the weather strip is secured to the bottom edge of the sash the guiding flanges 12 and 13 will extend vertically downward and in a plane with the inner and outer faces of the sash.

As the bottom of the sash extends into the sash guideways between the inside and outside sash stops, it is important that the guide strip does not extend beyond either theinner or outer faces of the sash, so that the weather strip may extend across the entire Width of the sash and between the inside and outside sash stops. The guiding flanges 12, 13, will guide the free edges of the felt so that they will project vertically downward, as denoted by the numerals 14., 15.

When the sash is closed the weight of the sash compresses the felt on the Window sill in two separate contact lines, as clearly shown in Fig. 3, and the inside felt edge 14.- will contact the sill cap 11 as well as the window sill 10, and at the side extremities of the sash these projecting felt portions 14, 15, will contact both the inside and outside sash stops. The felt, being resilient will mold itself to all inequalities of the window sill making a dust and air proof joint.

Again, referring to Fig. 2, it will be clear that any dust, dirt, &c., should it manage to pass between the stops 3 and the felt body and between the latter and the post 1, which is quite improbable, will be pocketed in the space 9 and will thence drop down onto the outside window sill 10, and in no event can pass the felt body that impinges against the inside stops 2.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is The combination of a window frame having side posts carrying inside and outside sash stops forming guideways for a sash, a sash movable in the guideways, said sash narrower than the width of the guideways and of lesswidth than the distance between the opposite posts, the side edges of said sash equipped with a felt weather strip so ar-' In testimony whereof I afiix my signature rangedf that it will compensate getwegn the in presence of two witnesses.
