MENTS, on ONE-HALF To PAULINE s. sEccoM n- I DRAFT nn NOISE sror Application filed March 27, 1929. Serial No. 350,288, I The bar (2-3) is slidably mounted'and This invention relates to draft, weather and noise stops for combination with doors, Windows and other closures anddivers structures. v

I am aware that it has been proposed to mount different forms of draft stops in grooves along the edges of doors and the like to prevent draft and noise from passing the edges when the structure is in closed posi- 0 tion. 2 i a It is an important object of the present invention to greatly simplify stops ofthe kind above referred to. 7

Another object is to provide an insertible 5 stop of few and substantial parts capable of easy installation and so operative as to make a good seal or closure by uniform contact with an adjacent engaged abutment, as a floor, or sill or stile or other part. Unless the effeco tive packing piece is pressed to position-by equal force one or'the other end of the piece will not seat and a draft escape is possible.

It is also desirable that the effective piece be brought to fully retracted position so as not 5 to drag at any part.

Other objects,advantages and features of- 7 construction and combination and details of means and the mode of operation will be made manifest in the ensuing description of the o herewith illustrative embodiment; it being understood that modifications, variations and adaptations may be resorted to within the spirit, scope and principle of the invention as it is more directly claimed hereinafter.

Figure 1 is a sectional elevationof the installed stop. 7

Figure 2 is a cross-section. Figure 8 is a sectional plan. Figure 4 is a perspective of the detached stop.

The present device includes a stuffing bar preferably formed of an inverted channel section 2 in which is secured a suitable mat 3 of packing material, of which felt is an appropriate type. mat is adapted to be pressed against acontiguous surface, as a floor, to stop noise and draft passage from one chamber to another,

or from the exterior to the interior of a room.

The bottom face of the is swung in a direction to of the bar-.1 Y Means are provided for, the unifronrup ward pull on the bar to retract, it to an ineffectivenormal positionand which means is adaptable without change to doors of various 'widthslto which stock strip of bar2 may be cut as desired. This means includes an elongated'leaf spring 6 niedially fiiied at 7 to the-top of the barv2'and havingits free ends supported on bridges 8-8 fixed in the shell 4 at such height that the bar when retracted by the spring will be clear of the floor, or sill if any.

The stufling bar is automatically pressed to effective position, as the door is closed on its hinges, by a ramrod 10 whose inner end is attached to a. lever 11 on a pivot or shaft 12 arranged just-above the medial part of the spring and operating on acam 13 fixed on the shell 2. The lever has a cam roller 14:

working on the cam.

WVhen the door is open.( Fig. 1) the spring. not only lifts the stufling bar but also rocks the lever. lland thrusts'the'rod 1O outward 7 so that its striker sleeve 15, adjustable by screwing along the rod, projects-well outside of. the hinged edge of the door D. 'A stop pin 16 limits the outward thrust of the rod.

As the door ismoved' to closed position the striker sleeve 15 engages a striking plate 17, fixed in the jambJ, and the rod is forced in against resistance of the spring 6 and the stufling bar is forced down to floor engaging positi0n, and is held so as long as the door is closed. 1 I r The pivot 12 is so disposed as to the cam 13 that as soon as the door opens the lever 11 push the rod outward again.

The striker sleeve 15 provides for the vari-.

'ation of the effective length of the rod to regulate action of the bar according to uduptutions.

The spring 6 is shorter than the bar so that it may he installed in narrow doors and is equally elfective in cases when the bars are cut from long stock to fit doors ct greater Width. I i

hat is claimed is:

A draft and noise stop strip comprising an elongated shell-having Qnopen bottom and adapted to be sunk in at grooved-edge cs'rrying parh an inverted channel section slide:

bly mounted for rise and fall in the shell an d having a packing exposed at its bottom, a bridge-like cam fixed medially to the top of the shell and a leaf spring secured under the bridge and having outwardly directed free ends, cross-hangers c in v the shell aboveithe packing section and on Whichsaid spring; ends rest and hichform top stops for the channel section, lever pivoted medially of its length and having on its lower end a roller engaging the top of the cnmte be actuated thereby through the spring; said lever being connected to and outwardly thrusting, a push rod, said rod projecting from the shell to engage a fixed abutment When the carrier is moved to a given position and whereupon, the packing device is bodily depressed to effective position; the spring having the dual function of lifting the packing and of projecting the push rod. o r l CLAYTON FIWYATT.
