WEATHER-STRIP.

Specification of Letters Patent.

Patented June 3th, M914.

Application filed March 2, 1914. Serial No. 822,006.

To all whom it may concern ie it known that I, J OIIN F. Poe, a citizen of the United States, residing at Oklahoma city, in the county of Oklahoma and State of Oklahoma, have invented certain new and useful Improvements in Weather-Strips; and .I do declare the following to be full,

'clear, and exact description of the invention,

such as will enable others skilled in the art to which it apperta ii'is to make and use the same.

This invention relates to improvements in weather strips and more particularly to those which are primarily designed for use in connection with window sashes and frames.

The primary object of the invention is to provide adevice of this character which will be simple in construction and efficient in operation and which may readily be applied to any window sash and frame without the necessity of making serious alterations therei n.

A secondary object is to construct one member of the strip in such a manner as to render it readily applicable to the groove in the window frame in which the parting strip is usually employed.

Still another object is to construct the fixed and movable strips in such a manner that escape of air between them will be practically impossible.

lVith the above objects in view, the invention resides in certain novel features of construction and combination herein described and claimed and shown in the drawings wherein Figure 1 is an inside elevation of a portion of a window frame and its upper and. lower sashes, showing the application of my invention; Fig. 2 is a horizontal section on the line 2-2 of Fig. 1; Fig. 3 is a. vertical section on the line 33 of Fig. 2; and Fig. 4 is a detail vertical section on the line 4.4 of Fig. 3.

In the accompanying drawings, 1 have shown my invention as applied to a window frame F which may be of any desired construction as long as it is provided with grooves G for the reception of the parting strips which separate the upper and lower sashes U and L.

The stationary member of my improved weather strip is formed of a single strip of sheet metal having its opposite edges bent in such a manner as to provide substantially parallel. flanges 2 which are adapted to project inwardly from the sides of the frame F when said member is forced into the groove G as clearly shown in Fig. 2.

Coat-ting with the fixed member, are movable members 3 which are also formed of single strips of sheet metal. l'iaving one of their edges secured as at 4 to the sashes U or L while the remaining portions of said strips are bent substantially upon themselves as at 5, said bent portions cont-acting with the inner side of the frame F, their remaining portions being then bent rather loosely around the 'free edges of the flanges 2 as shown at (3 and then extending inwardly inside of said flanges, formed with inwardly extending beads 7 and having their terminals 8 in contact with the inner sides of said flanges 2. By referring to Fig. :2, it will be seen that the only points ofcontact between the movable members 3 and the flanges 2 of the stationary members are at the bends 6.

and at the free terminals 8 of said members 3. By this construction and positioning, the passage of air around the ends of the flanges 2 and past the ends 8, is rendered practically impossible and yet all unnecessary friction is avoided. The beads 7 when the sashes are moved, run freely within grooves 9 formed in the opposite sides of a parting strip 10 which is forced between said beads and the flanges 2 and is held in position by said beads, no other fastening being necessary. It may be noted here also that by the construction and arrangement of the fixed and movable members, no fastening means are required for retaining said fixed members in position within the grooves G, the only points at which the improved strip is rigidly secured being at the points 4 where screws are preferably employed in order to render the various parts readily removable.

The location of the various thicknesses of metal between the contiguous edges of the sashes U and L and the opposite sides of the groove G, in which the parting strip 10 was formerly secured, will necessitate moving said sashes away from said groove to a suitable extent. This necessitates the moving of the remaining strips S which guide said sashes in their movement and also causes considerable space to be left between the lower rail R ofthe upper sash U and the upper rail r of the lower sash L. It therefore becomes expedient to provide a simple means for preventing the entrance of air rail 4-.

through this space and for this purpose, I

have provided a strip 11 of resilient metal which is secured to the rail R by suitable fastening means 12 /along its upper edge while its lower portion is bent in such a manner as to cause its extreme lower edge 13 to contact with the continuous edge of the This means, though simple, effectually point.

In order that the ends of the rails R and 1 may move freely in respect. to the inner edges of the iarting strips 10, I preferably space said chilsa proper distance from said strips. This necessitates the provision of means for preventing the entrance ofair at this point, said means being here shown in the form of fiat metal springs 14 which have their opposite ends embedded in suitable notches formed in the parting strips 10 and secured therein by screws 15 or other suit able fastening means. By reference to Fig. 2, it will be seen that the springs 14 are of the same width as the parting strips 10 and that the ends of the'rails R and 1" as well as the metal stri '11 contact with said springs, when the sas es are closed, and thus effectually prevent the entrance of air. When it is necessary to raise the lower sash or lower the upper sash, the engagement between the ends of the rails R and r and the springs 14 will be released upon a slight movement of said sashes whereupon they will be free to be raised upwardly or downwardly as the case may be.

I have before mentioned the fact that by the specific construction and positioning of the fixed and movable parts of my improved weather strip, no fastening elements are necessary for the purpose of securing the U-shaped strip 1 and the parting strip 10 in position. Attention is again directed to this fact since, in the manufacture of the device, it becomes a very salient feature.

From the foregoing description, taken in prevents the .entrance of air at this connection with the accompanying drawing, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in form, proportion and minor details may be resorted to without de-- parting from the spirit of the invention as claimed.

Having thus described my invention, what I claim as new and desire to secure by Letters-Patent is:

The combination with a window frame having upright grooves formed in its side members and upper and lower sashes slidable on opposite sides of said grooves, of a strip of-n1ctalU-shaped in cross section, in each of said grooves and extending throughout the height of the frame, the free edges of said strip projecting into the interior of the frame, and a movable member carried by each of said window sashes, said movable members being formed of single strips of sheet metal bent upon themselves to one side of their longitudinal centers, their narrower portions being secured to the contiguous sides of said sashes, and their wider portions being bent substantially upon themselves around said free edges of the U-shaped strip and formed into inwardly extending beads, the edges of said wider ortions being in yielding contact with the inner sides. o the inwardly projecting portions of said U- shaped strips, and the beads in said wider portions contacting with the inner edges of said strips, and a grooved parting strip within said U-shaped strips and retained threin by said beads.

In testimony whereof I have hereunto set -my hand in Presence of two subscribing witnesses.
