The present invention relates, 'broadlyyto i improvements in weather-str ps for doors and like swinging. closures, but moreparticularly to improvements in antmnatically'aetuated weather-strips wherein the strip is automatically retraetedvinto a'rec ess in the bottom edgeof the closure when swung'open r and is dropped'to operativeposition when the a and operative positions.

The device inthepresent invention isof a simple and effioientfloharaeter and embodies a hinged strip of metalhaving a riibber strip secured therein, which rubber strip ispressed against the floor whenythe door, or otherclosure, is'in closed position, and is raised clear of the floor when thejolosur'e is opened," the means for actuating the sameg-being wholly automatic and operated through the swinging action of the closure. i

'The primary. object of the invention isto providean automatically operated weathen strip for doors and like closures that is simple; in constructionand positive in its action. i 7 Another object of the invention is to pro ride an automatically operated weather-strip of the Class indicated that will automatically swing clear of thefioor whengthe olosure'is opened and that willbe automatically urge-d position when the closure IE.

' Another object of the invention is the provision of novel means forthe automatic actuation of the weather-strip tobothretracted ing the same, the section being indicated by" I the line 22, in Figure l;

' Thelower edgefof the closure is grooved,

as indicated at 13, providing a tongue 14 on its inner edge extending the full width of the closure,.as'olearly indicated in Figure 3. i The weather-strip 15 isip ositioned in this groove and-has itsrearedge lfjabutting against the tongue 114: when in position on the closure.

The Weather-strip per se coinprises a strip of metal,

said stripil9 being securely held in/place by suitable manner after the ru ()ne endedge of'one of the thestripis bent upland over. the other, as indicated at 20 in Figure '5, whilethe opposite end oi" both sections and18 are bent up at right anglesto t-hebodygof, theistrip at the opposite end thereof to form an actuating 121, F iguzres 2L M 15 Spr ng means 22 is provided for normally in the SeCtl0I1- ;17- df;ftl1Qf Stllp with the upstand ng seot on- .23 projecting upwardly theirefron fas,indicated in Figures 3, 4

preferably galvanized iron, bent 'npon' itself and forming upper and lower gripping members 17 andlS between the free edges of which is inserted a rubber strip v19,.

. thegolainpingiactionof the members 17 and 1, o 18, which are pressed tightlyltogether in any:

bber strip has nemhers l8 of retracting thestrip and embodies an elon- V jgatedsection of steelwire having at Ione end I anupstanding seotion 23and atthe other end hook section4 24.,l,;'llhis spring, as thus: iformed, is inserted through a vslot 25 formed The hook section 24 of the spring lies fiatwise between the sections 17 and 18 of the strip and when said strip is in place the upstanding section 23 thereof projects into a hole 26, Figure 3, provided in the closure for its reception.

In attaching the strip to the closure 9. plurality of openings 27 are provided in the inner edge 16 thereof and a plurality of staples 28 are inserted through these openings and driven home into the inner edge of the closure, as indicated in Figure 3, these sta les forming hinge members providing for ree swinging movement of the strip relative to the closure.

The spring 22 having a torsional ur e tends to normally hold the strip retractec in the groove 13 of the closure and substantially flush with the lower'edge of the tongue 14: thereof.

The arm 21 of the strip when in place upon theclosure, lies flat against the lower free corner thereof, as indicated in Figure 2, with this arm projecting into the path of a stop 29 positioned on the inner sideof the casing member 30, so as to engage the arm 21 of thestrip when the door is in closed position and force the same to the position shown in Figure 3, or in operative position with the rubber strip 19 engaging the floor.

When the closure is opened the arm 21 leaves the stop 29 and the strip is instantaneously forced to inoperative position in the groove '13 by the torsional urge of spring When the strip is in operative position, as in Figure 3, the rubber strip 19, being resilient, presses downwardly against the floor and tightly seals the opening between the lower-edge of the closure and the floor, thus preventing the entrance of undesiralfile drafts through this channel.

The strip, of course,-niay be applied to various closures such as swinging windows and the like, and will serve to prevent drafts from this source equally as well.

Having thus described claim and desire to secure by Letters Patent of the United States,the following:

1. A weather-strip adapted to be liingedly secured to a swinging closure between one edge thereof and its frame, said strip comprising a metal strip bent upon itself to form a clamp, one of the members of the clamp having an end portion bent to overlap the other member of the clamp, an upwardly extending integral arm on one end of said clamp,,a spring rod carried by the clamp, said rod having an arm extending upwardly from the clamp and mounted in a recess in the closure, said rod'having a flat hooked end fitted in the bend in the clamp.

2. A weather-strip adapted to be hingedly secured to a swinging closurebetween one edge thereof and its frame, said strip commy invention I in the closure.

In testimony whereof, I hereunto afiix my signature.
