noon ATTACHMENT.

Specification of Letters Patent.

Patented Aug. 2, 1921.

Application filed February 12, 1919. Serial No. 276,612.

To all whom it may concern Be it known that I, FRANK O. SwnNsoN, a citizen of the United States, residing at Austin, in the county of Travis and State of Texas, have invented new and useful Improvements in Door ttaehments, of which the following is a specification.

This invention relates to a weather strip attachment for doors, and has for its object to provide means whereby the strip will be automatically brought in tight engagement with the carpet strip of the door frame, when the door is in closed position and which will further automatically move away from the carpet strip upon the opening of the door, so as to provide no obstruction to the free opening or to the free closing of the door.

A further object of the invention is to produce a weather strip which may be readily applied to any ordinary constructlon of swinging doors or the like, the construction of Weatherstripping being of a simple nature, and the arrangement of the parts thereof being such as to insure automatic action in projecting the strip below the door when the door is closed and in elevating the strip above the lower edge of the door when the door is open.

Other objects and advantages will present themselves as the nature of the invention is better understood, reference being had to the accompanying drawing, in which:

Figure 1 is an elevation of a door and easing therefor, parts being broken away to illustrate the application of the improvement, the door being in its closed position.

Fig. 2 is an enlarged detail sectional view approximately on the line 22 of Fig. 1.

Fig. 3 is a sectional view approximately on the line 3-3 of Fig. 2.

Fig. 4 is a view similar to Fig. 1, but illustrating the weather strip in retracted position, as when thedoor is open.

Fig. 5 is a sectional view approximately on the line 55 of Fig. 4:.

Fig. 6 is a perspective view of the operating rod.

Fig. 7 is a similar view of one of the yokes employed.

Referring now to the drawings in detail, a swinging door is indicated by the numeral 10 and the casing for'the door by the numeral 11, while 12 indicates the carpet strip.

The door has its lower edge plowed longitudinally providing the same with a continuous pocket 13, and the ends of this pocket may be closed by suitable plates 11, or if desired the pocket need not extend the entire width of the door, in which instance the plates 14 may be dispensed with.

The top wall of the pocket, adjacent to the ends of the door is bored, to provide sockets 15 and in these sockets are secured springs 16 that have their outer convolutions secured in eyes 17 that are centrally' formed in substantially U-shaped yoke members 18. The limbs of the yokes have their ends also provided with eyes, the said limbs straddling the upper portion of a substan tially cross sectionally rectangular weather strip 19, and securing elements 20 passing through the eyes and entering the said weather strip. By this arrangement the weather strip, which it should be stated extends the entire length of the pocket 13 is drawn upwardly in the said pocket so that the outer edge thereof, which is preferably provided with a compressible facing, is elevated above the lower edge of the door.

Secured to the top wall of the pocket 13, adjacent to the ends of the said pocket are brackets 21 having openings therethrough which provide bearings for the longitudinally movable operating rod 22. The rod 22 projects through one end of the pocket '13, the said projecting portion being preferably provided with a flat head 23, and this end of the rod is normally projected through the said. pocket by the influence of a spring 24 which is arranged on the rod and which exerts a pressure between one of the brackets 21 and a pin or lug 25 on the said rod. The rod is arranged above the strip 19 and is movable through the arm or limbs of the yokes 17.. The rod, adjacent to the ends thereof, has secured upon the lower face thereof angle elements which provide cam members and which are designated by the numerals 26. The upper edge of the strip 19 is provided with similar cam members 27, the outer beveled edges being at an opposite inclination from those of the cam members 26.

In the rabbet provided in the casing 11 in which the door 10 is hung, is secured a contact plate 28 disposed to be engaged by the head 23 of the rod 22 when the door is in its closed position. Such engagement forces the rod inward of the pocket, causing the cam surfaces 26 thereof to travel over the cam surfaces 27 of the strip 19, and conse outwardly of the pocket 13 against the tension of the springs 16. When the door is swung to its open position the head 23 will be free of contact with the plate 28, permitting the spring 24 to expand, moving the rod longitudinally to bring the camelements thereon out of engagement with the cam elements on the strip and allowing the springs 16 to draw the strip inward of the pocket. i V v Itis of course, obvious that the contact plate 28 may be dispensed with and that I am not to be limited to the details of the construction above set forth, but am entitled to all such changes therefrom as fall within th scope of what is claimed. 7

Having thus described the invention, what is claimed as new, is

In combination with a hinged door provided with a pocket disposedlongitudinally v of its base and communicating'with sockets formed therein adiacent to its ends, a coil spring secured in each of said sockets, a depressible weather strip disposed in said pocket, U-shaped yoke members connected to said springs and secured to said strip, brackets secured to the inner wall of said pocket, a longitudinally movable operating rod'carried by said brackets, provided with a flat head, and guided by said brackets and projecting through one end of said pocket, a lug extending from one side of said'rod, a spring surrounding said rod and exerting a pressure between said lug and one of said brackets, cam elements formed on the up.- per edgeof said strip,':cam elementsformed on the lower face of said rod and adapted to engage the first mentioned cam elements to force the weather strip outward against the tension ofthe last mentionedspring.

In testimony whereof I afiix my signature.
