Application'Octob'er 16, 1951, Serial No. 251,531

Claims; (CI. 20-65) Fig. 1. The back plate 4 is provided nearits center with a vertical slot 6, Fig. 4. Within the sectional casing 2a is a split rotatable cylinder opens outwardly, or a door that opens inwardly.

A still further object of the invention is to produce an efficient device that will fit tightly the door and jamb, as well as sealing the door against drafts and other disagreeable conditions. Further, this device will function'with or without a door-sill.

The invention of this application is an improvement upontheinventio-n disclosed in my United States Patent N 0. 2,565,393, issued August 21, 1951.

With the foregoing and other objects in view, this invention comprises certain novel constructions, combinations, and arrangements of parts as will be hereinafter fully described, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims.

In the drawings:

Figure 1 is a view in front elevation of a device constructed in accordance with this invention, showing same applied to a door that is intended to swing inwardly.

Figure 2 is a fragmentary end view of a door frame and a (1001' to which my invention is applied.

Figure 3 is a view in end elevation of the device in a closed position.

Figure 4 is an enlarged sectional view, taken on line 4-4, Fig. 1, and looking in the direction of the arrows.

Figure 5 is a view similar toFigure 1, showing a modified form of the device applied to a door that is adapted to swing outwardly.

Figure 6 is a View in end elevation, showing the door frame and door with my device applied thereto, in an open position.

Figure '7 is a view in end elevation, showing the device of Figure 6 in a closed position.

Referring to the drawings, in which the preferred specie of this invention is shown in Figures 1 to 4, I designates the door frame and 2 the inwardly swinging door.

The device comprises a sectional casing 211 consisting of a cover plate 3 and a back plate 4. These two plates are held together by screws 5,

or sleeve '1. This sleeve 1 is provided with a transverse slot 8. A comparatively flat spring!) has its upper end in slot 6. -The lower portion of spring 9 is in the slot 8 and presses against the lower end of the slot, as clearly shown in Fig. 4. An elongated-seal In is mounted on the split sleeve 1 and extends the entire length of said sleeve. spaced longitudinal grooves ma selectively engageable by one edge of said'split. This structure permits adjustment of seal H] in and out of the sleeve '1. e

A nut I l is placed in the upper portion of slot 5, with the springs bearing against same. A

screw 5 extends through the upper portion ofthe cover plate 3 and through spring 9 and the nut ll, whereby the spring 9 i's-held in an excellent position. I

The rotatable sleeve '1 is provided on its ends with lugs I2, which are adapted to engage adjustable screws 13. When the door 2 is moved to a closed position, the lug I 2 comes in contact with the screw l3, resulting in the sleeve being rotated, from the position shown in Fig. 2 to the closed or sealing position shown in Fig. 3. As

soon as the door is beginning to move to an open.

position, the spring 9 will begin to rotate the sleeve 1, whereupon the seal ID will begin to move upward until it is in its open position, as shown in Fig. 4.

The embodiment shown in Figures 5 to 7, is substantially the same with reference to the spring construction, as described for the embodiment of Figures 1 to 4. In this embodiment, the lugs or triggers 12a are placed in a relatively higher position on the ends of the rotatable sleeve 1, and the screw l3a is also placed parallel on the door frame I so that the trigger or lug 12a will strike against the screw 13a, causing the seal ID to be moved to a closed or sealing position when the door is entirely closed. On the outer ends of the back plate 4a are formed rightangled brackets [4. These brackets l4 serve to hold the rotatable sleeve securely within the sectional casing.

One of the advantages of my construction is that the seal can be cut off at either end to fit a job, irrespective of the width of the door. This can be more readily accomplished when using the seal device of Figures 1 to 4.

While I have described the preferred embodiments of the invention and illustrated the same The seal l 0 is provided with transversely in the accompanying drawings, certain minor changes or alterations may appear to one skilled in the art to which this invention relates during the extensive manufacture of the same, and I, therefore, reserve the right to make such changes or alterations as shall fairly fall within the scope of the appended claims.

What I claim is:

1. In a device of the class described, the combination of a sectional casing comprising a cover plate and a back plate, said back plate provided with a transverse slot, a, rotatable split sleeve in said casing, said sleeve provided with a slot registering with said first-mentioned slot, a spring fastened to said casing and positioned in said registering slots and exerting pressure at all times on said sleeve, and said sleeve being provided with a seal, said seal consisting of an elongated strip extending through the split of the sleeve and provided with transversely spaced longitudinal grooves selectively engageable by one edge of said split.

2. In a device of the class described, the combination of a casing provided in its back with a vertical slot, a rotatable split sleeve in said casing,

said sleeve provided with a slot registering with said first-mentioned slot, a spring fastened to said casing and positioned in said registering slots and exerting pressure at all times on said sleeve, and said sleeve being provided with a seal, said seal consisting of an elongated strip extending through the split of the sleeve and provided with transversely spaced longitudinal grooves selectively engageable by one edge of said split.

3. In a device of the class described, the com-- bination of a casing, a rotatable split sleeve within said casing, a spring mounted on said casing and extending into said sleeve, said spring at all times exerting pressure on said rotatable sleeve, and a seal carried by said rotatable sleeve, said seal consisting of an elongated strip extending through 4 the split of the sleeve and provided with transversely spaced longitudinal grooves selectively engageable by one edge of said split.

4. In a device of the class described, the combination of a sectional casing, a comparatively fiat spring secured between the sections of said casing, a rotatable split sleeve within said sectional casing, said rotatable sleeve provided with a slot, said spring extending into said slot and exerting continuous pressure upon said s1eeve,and a seal carried by said sleeve, said seal consisting of an elongated strip extending through the split of the sleeve and provided with transversely spaced longitudinal grooves selectively engageable by one edge of said split.

5. In a device of the class described, the combination of a casing provided with right-angled brackets extending from the back of said casing, a rotatable split sleeve within said casing, a spring carried by said casing and pressing continuously against said sleeve, and a seal carried by said sleeve, said seal consisting of an elongated strip extending through the split of the sleeve and provided with transversely spaced longitudinal grooves selectively engageable by one edge of said sp it.
