SPECIFICATION forming part of Letters Patent No. 549,448, dated November 5, 1895.

Serial No. 542,403. (No model.)

To all whom t moby-concern:

Be it known that we, LEON DEPP and MosEs SCHLATTER, citizens of the United States, residing at Inman, in the county of McPherson and- State of Kansas, have invented certain new Aand useful Improvements in Weather- Strips; and we do hereby 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.

Our invention relates to improvements in weather-strips, and has particular relation to hinged strips employed in connection with doors.

The invention consists of certain novel constructions, combinations, and arrangements of parts, all of which willbe hereinafter more particularly set forth and claimed.

In the accompanying drawings,forming part of this speciication, Figure l represents a central vertical section through a door and casing, with our improved weather-strip applied to the former, said strip being shown in its lowered position. Fig. 2 represents a central vertical section through a door, showing the strip in its raised position. Fig. 3 represents a detail side elevation of one side of the door-casing, showing the inclined undercut, which forces the strip into its lowered position. Fig. 4 represents a detail perspective view of one side of the casing and the floor, showing the projections or buttons which take the place of the inclined undercut and the carpet-strip for lowering and raising the weather-strip; and Fig. 5 represents a detail top plan view of said weather-strip.

A in the drawings represents the door-casing, A the door, and B the hinged weather- The weather-strip is preferably made of wood and is beveled at its rear edge and hinged to the outside of the door near the bottom by any suitable hinges b. The strip extends the entire width of the door and is provided at its outer edge with a longitudinal diagonal groove adapted to receive the packing-strip b', of rubber, felt, or similar material. We preferably attach a strip bito the door above the hinged strip to act as a stop to limit the upward movement of the latter, but this strip is not essential, as the spring strip holding devices accomplish the same result.

link b5, pivoted at one end between said split portions, and a bowed spring b, having one end passed through an aperture in the outer end of the short link and the other end turned downward at an angle to enter a recess in the strip B, a plate b7 being attached to said strip over said'end of the spring to secure it in place.

The shape and tension of the spring is such that when the strip B is forced into an approximately horizontal position the upper end y of the link b5 is thrown to the rear of its center or pivotal point, with the result that the tension of the spring tends to force said link farther to the rear of its center. To depress the front edge of the strip B it is necessary to use force until the outer end of the link passes forward of its center, when the action of the spring will tend to throw the link still farther forward of its pivotal point, which will result in the front edge of the strip being depressed until its packing edge contacts with the floor, where it is held under springpressure.

In the ordinary construction of doors there is a bottom sill f and side stiles j f2, and in such a construction we utilize the inclined face of the sill f to force the strip B upward.

as the door opens, and the spring will hold the strip in such raised position out of any contact with the floor until the door is closed. The stiles f f2 are undercut on each side to permit the strip B to pass into the casing as the door is closed. The said strip comes in contact with the undercut portion of the stile f as the door is closed and thus said strip is forced into its lowered position and kept so under spring-tension, thus forming an approximately air-tight joint between said strip and the floor.

The outer end of the strip B is beveled, as at bs, and the casing cut away, as at a', so that the door can close without the end of the strip coming in contact with the casing. Vhen the doorway is provided with neither sill nor stiles, the devices shown in Fig. 4 are employed to raise or lower the hinged strip as the door is opened or closed.

IOO

The device for raising the strip consists of a projection or block 7L, having an inclined top surface and provided with apertures through which screws pass to secure the same to the fioor. The strip B strikes the incline surface in the same manner that it strikes the sill when the door is opened.

The device for lowering the strip consists of a-n angular bracket J, having screw-holes j, and secured to the casin g in an inclined position, so as to occupy the position ot the stile This bracket acts in the same manner as the undercut portion of the stile f to force the strip downward when the door is closed.

lith our invention we secure approximately an air-tight joint between the bottom of the door and the ioor and at the same time provide means for automatically lift-ing the devices forming said joint into a raised position out of contact with the iioor, upon the opening of the door. VWe also provide means for automatically depressing said strip when the door is closed and keeping it in sueh depressed position in contact with the ioor under spring-pressure.

\Vhen our device is applied to very large doors it is not necessary to cut away the casing, as at a, as the swing of the door is great enough to allow the hinged strip, which is the widthot' the door, to pass almost straight into the doorway. The beveled end b5 can also be done away with when the device is used in connection with such a door.

lYe contemplate forming one member of a hinge on the plate 11T and another on the plate Z13, and by joining these members form one of the hinges for the said hinged strip B.

llavin g now described our invention, what we claim as new, and desire to secure by Letters Patent, is

l. The combination with a door, of a weather strip hinged thereto, a link pivoted on said door and a spring connecting said link and said strip whereby the latter may be sprung into either a raised or lowered position and remain so under spring pressure, substantially as described.

2. The combination with a door, oli' a weather strip hinged thereto and provided at its outer edge with a rubber or like packing strip, a link hinged to said door, and a bowed spring connecting said weather strip and link; the construction and operation being such that the link is thrown to the rear ot its pivotal point when the weather strip is elevated and vice versa when it is depressed and held so by the spring thus holding the weather strip either up or down under spring pressure, substantially as described.

3. rlhe combination with a door, of a weather strip hinged thereto, a link pivoted on said door, a spring connecting said link and said strip whereby the latter may be sprung into either a raised or lowered position and remain so under spring pressure, a door sill for forcing said wea-ther stri p upward, and door stiles having undercut portions adapted to force said strip down, substantially as described.

i. The combination with a door of a weather strip hinged thereto, a link pivoted on said door, a spring connecting said link and said strip whereby the latter may be sprun into either a raised or lowered position and remain so under spring pressure, and means for automatically raising and lowering said strip as the door opens or closes, substantially as described.

In testimony whereof we hereunto affix our signatures in presence of two witnesses.
