WEATHER-STRIP.

Specification of Letters Patent,

Patented Dec. 3, 1907.

Application led April 5| 1907. Serial NO- 366.616.

To all 'whom it may @encerrar Be it known that I, ALBERT BUJEwsKI, a citizen of the United States, residing at St. Louis, in the county of St. Louis Oity and State of Missouri, have invented a new and useful Weather-Strip, of which the following is a specification.

This invention relates to a weather strip to be applied to windows and doors for preventing the entrance of cold air and rain, the main object of which invention is to produce a weatherI stripof suoli construction that when secured to the side or sides of a window sash or door, it will when the sash or door is opened, beautomatically drawn awayfroin the window or door frame and permit the sash to be raised and lowered or the door to be opened without frictional contact of'the weather strip with the said frame, but on fully closing the window sash or door, suitable devices will be broughtinto opera tion to force the weather strip tightly against the window or door frame and effectually exclude all cold air and rain.

In the accompanying drawings :-Figure 1 is a view inelevation of a part of a window sash with my invention applied thereto, a portion being shown in section. Fig. 2 is a cross sectional view on the line 2-2 of Fig. 1, enlarged. Fig. 3 is a vertical central sectional view of the invention detached from a window sash. Fig. 4 is a view of the lower part of a door with the weather strip attached to the bottom thereof. Fig. 5 is a cross section on the line 5 5. Figs. 6 and 7 are respectively views of the rear and front edges of the bottom of a door showing the securing plates for sustaining the weather stri l Siinilar numerals ofA reference are employed to indicate corresponding arts throughout the several iiguresof the rawings.

t window sash indicated by 1 is grooved in one or both sides, as at 2, from the bottom to or near the top thereof into which groove is inserted a channel bar 3 made of wood or metal, having a straight bottom 4 and parallel sides 5 perpendicular to the bottom 4. i

Within the channel bar 3 and bearing against its bottom'4 is a longitudinally movable operating bar 6, its sides bearing against the sides of the channel bar 3 and extending from the bottom of said channel bar to near its top.

Resting against the outer side of the operl ating bar 6 and extending the full length and width of the channel bar 3 is a fixed separating strip 12, on the inner face of which at each side is a flange 13, each flange tting a suitably formed rabbet in an edge of the operating bar 6. The separating strip 12 is held in place in the channel bar by means of nails or screws 14 or other suitable means, as shown, and has its outer face recessed at 15 as clearly indicated in the drawing, the purpose of these recesses will be disclosed later.

, Next the separating strip 12 and in contact therewith except when the window sash is completely closed is a rectangular rod 16, the full length of the channel bar 3, and provided on its outer face throughout its entire length with a groove 17 in which is securely seated a resilient packing 18, preferably rectangular in cross section, projecting slightly beyond the outer face of its containing rod 16, For convenience in describing the invention, the rod 16 and its resilient packing 18 will be called the weather strip. On the inner face of the weather strip project a plurality of cam studs 19, extending through openings 20 in the separating strip 12, and so disposed that the cam surface on the lower side of each stud is, in the relaxed position of the parts, just above a roller 10. From this it may be observed that when the operating bar 6 is raised, the rollers 10 acting on the cam studs will force the weather strip outwardly.

Secured to the back of the rod 16 opposite each recess 15 in the separating strip 12, is a fiat spring 21 fastened in place by a screw or rivet 22 passing through its center. The ends of each s ring, which are free, extend under flat resilient metal plates 23 fastened at one end to the separating strip 1'2 within each recess 15, forming thereby a spring connection between the separating strip 12 and the weather strip 16.

When this weather strip is used in connection with a window sash, one or both sides of screws 14. An aperture 30 is made in the said sash are grooved and a channel bar 3 seated in each groove and secured in any desired manner. The coiled spring 8 bearing against a part 24 of the sash frame l tends to keep the operating bar 6 pressed downward and the rollers l0 away from the cam studs y 19, thereby permitting the flat springs to recoil {ijhand draw the weather strip into the channel bar 3. In this position the window may be raised and lowered with the greatest ease as the resilient packing 18 is entirely out of contact with the window frame. When the window sash is closedjjLthepin 9 coming in contact with the bottom of' the window frame holds the operating bar stationary, while the remaining parts of the device are descending. As the cam studs 1-9 come in contact with the rollers 10, the weather strip is forced laterally from the channel bar against the sides of the window frame.

What has been said heretofore in connection with placing this device on a window sash is equally applicable when applied to doors and other closing devices. In attaching the weather strip to a door, and especially on the bottom edge, a groove 25 is first made in the bottom edge of the door of a' size to receive the channel bar or casing 3 of` the weather strip. The weather strip eX- tends from the front edge to the rear edge of the door, and is held in place within said groove by a plate 26 set into the front edge of the door and a plate 27 ilush withthe rear edge. Screws 28 secure the

plates

26, 27 to the door, but for attaching the weather strip to the plates, screws 29 pass through said plates into the ends of the separating strip l2 fastened to the channel bar 3 by nails or rear plate 27 through which the pin 9 projects, so that when the door is closed, the

, pin 9 striking the door frame slides the operating bar 6 endwise and forces the resilient packing 1S against the door sill.

I clairn:-

1. A weather strip comprising a casing, a longitudinally movable bar, a transversely movable bar, a ixed separating strip between the two bars, coperating means carried by the two bars for causing one of 'said bars to move the other in a direction transverse to the movement of the iirst mentioned bar, and interlocking spring plates fastened to the separating strip and to the transversely movable bar.

2. A weather strip comprising a casing, a longitudinally movable bar, a transversely movable bar, a fixed separating strip between the two bars provided with through openings and exterior recesses, cooperating means within said openings carried by the two bars for causing one of said bars to move transversely when the other is moved longitudinally, a spring plate centrally iastened to the transversely movable bar opposite each recess in the separating strip, and other spring plates in the ends of said recesses arranged to overlap the ends of the spring plates on the transversely movable In testimony that I claim the foregoing as my own, I havehereto affixed my signature in the presence of two witnesses.
