Application March 19, 1943, Serial No. 479,765 2 claims. (o1. '2d-.68)

My invention relates to doors, and has a'mong its objects and advantages the provision of an imprdved door seal.

In the accompanying drawing:

Figure 1 is a face view of the bottom end of the conventional door illustrating my invention applied thereto.

Figure 2 is a sectional view along the line 2-2 of Figure l.

Figure 3 is a fragmentary sectional view of the door in apartly opened position.

Figure 4 is a sectional View along the line 4-4 of Figure 1.

Figure 5 is a sectional View of the bottom end of the door.

Figure 6 is a perspective view of aseal actu-` ating wing, and

Figure 7 is a face view of a guide plate and spring attachment.

In the embodiment of the invention selected for illustration, the door il) is provided with a groove l2 in its lower end face M. Inside this groove is mounted a sealing plate it having angular slots i8 loosely receiving correspondingly angled wings 20 attached at 22 to the door It. Recesses 26 are formed in the end face M for the ears 28 on the wings 2t to bring the ears flush with the end face of the door. Figure 6 illustrates the ears 28 of that wing 2li spaced so that the sealing plate i6 may move therebetween for engagement with the sill 3D. Each ear 28 is provided with an opening for the reception of one of the fastening screws 22.

While the slot i2 is relatively narrow to guide the plate it in its vertical movement, the door is cut out at 32 to provide accommodation for the wings 2t. Figure 5 illustrates the position of the plate it when the door It is opened. In this position, the shoulder 3ft at one end of the plate engages a stop plate 36 secured to the vertical edge 38 of the door. A slot il!) is provided in the plate 3S for accommodating a projection 42 on the plate it. A tension spring tft is connected at one end with the plate 36 and at its other end with the plate it to yieldingly hold the latter in the position of Figure 5.

The door frame structure iti is recessed to receive a plate 48 made secure by screws 5t. The plate 48 is located for engagement with the projection t2 as the door lll is being moved to a closed position. With the door lt opened, the tension of the spring llt pulls the sealing plate I 6 into engagement with the stop plate 36 and elevates the plate l5 by reason of the angularty of the slots I8 and the wings 2i). As the door swings to a closed position, the plate la engages the extension 42 and shifts the sealing plate It in the opposite direction to bring its lower edge into engagement with the sill im and thereby provide an eiective weather seal.

Without further elaboration, the foregoing will so fully illustrate my invention, that others may, by applying current knowledge, readily adapt the same for use under various conditions of service.

I claim:

1. A door provided in its lower edge with a groove, a sealing plate located within said groove and provided with slots inclining upwardly from its lower edge, the groove being slightly wider than the thickness of the sealing plate and provided opposite the slots of the sealing plate with widened portions, wings of greater width than the groove and fitting in said widenedportions thereof, the wings being each provided at its lower edge with a pair of spaced ears located at opposite sides of the groove .and secured to the lower edge of the door, the wings extending acrossthe groove and arranged at an inclination similar to that of the slots and fitting in the slots to support the sealing plate for downward or upward movement with relation to the lower edge of the door, a slotted stop plate secured to one vertical edge of the door with its slot in registration with one end of the groove, a coil spring secured to the sealing plate and to the stop plate, a shoulder on the sealing plate contacting the stop plate, and a projection onl the sealing plate extending through the slot of the stop plate.

2. A door provided in its lower edge with a groove, a sealing plate located in said groove and provided with slots inclining upwardly from its lower edge, the groove being slightly greater in width than the thickness of the sealing plate, wings located in said groove and extending entirely across the same, the wings being inclined similar to and ltting in said slots to support the sealing plate for angular downward or upward movement with relation to the lower edge of the door, relatively spaced ears on the lower ends of the wings secured to the lower edge of the door, the ears of eachwing being located at opposite sides of said groove to permit the passage of the sealing plate between the same, means acting on the sealing plate during the closing of the door to effect the downward movement of the sealing plate, and means acting on the sealing plate during the opening of the door to effect the upward movement of the sealing plate.
