Patented July 18, 1933 PATENT HARLEY M. PURDY, or wABAsn, mniaimj SPRING-PBESSED WEATHER STRIP AND ITS SPRING-PRESSED ACTUATOR Application filed May as, .1930. Serial in); 456,503.

This invention relates to double doors, and especially to an astragal or spring pressed weather strip and its springpressed .actuator. i One object of the invention is to eliminate d'ifliculties encountered with the ordinary astragal over the crack or opening between two door-members of a: double door, where the astragal or weather strip is fixed on one'of the door-members, and where the door-meniher that has-the astragal can not be closed while the door-member having-no vastragal is closed. In such ordinary construction, the

astragal is likely to be broken or defaced by $5 striking or being struck by a belt or latch of the lock of the door. I Y i Another object is to provide a double door with an astragal having yielding means to hold it out of the way ofthe door-member 29 which has no astragal thereon. 1

Another ob 'ect is to provide an effective spring-pressed means to automatically press the astragal in its weather-excluding position and to hold the door-members against rattling in consequence of the wind blowing against them.

Other objects and important features are pointed out or implied in the following description, in connection with the accompany- 39 in; drawings in which:

Fig. 1 is an elevation of a double door provided with my invention, as viewed from the interior of a room closed thereby, the mid dle part of the door-frame, door and astragal. being broken out, and a part of the threshold beingshown in section; r

Fig. 2 is an elevation showing the doorframe from the opposite side or outside, .a part of thcfra ne andthreshold being broken off-parts of the threshold being in section. and the door-members being open and having their middle parts broken out. 7

Fig. 3 is a horizontal sectional view, the section being taken along line 33 of Fig. 1.

Fig. lis a view similar to 3, except the securingbolt being omitted, the astragalcarrying door-member being open, as shown in full lines and in broken lines, and a part of thie doorTfra-me and threshold being broken 0 as follows Fig. 5 is a top plan view of the lower casing-member and the springprcssed cam'that pushes the astragalinto its closed position shown in Figs. 1 and 3, a partof this cam or pusher being shownin section. V

. Fig. 6, is an inverted plan view of the cover of the casing-member shown in Fig.

Fig. 7 is a viewsimilar to Fig. 6, but showing a modified form of the spring-pressed pusher or came, one of the two springs being omitted to show the bosses or spring-retain ers.

.Referringto these drawings in detail, in-

which sin1ilar reference numerals and letters refer to similar parts in thevseveral views, the inventlonwill now be described 111 detail The doors or doo r-menrbersA and B, the door-frame C, and the hinges D may he of- I any usual or preferred construction, mate-.

rials and. dimensions, and any preferred and proper kind of fastening means may be provided for the door-nieinbcrs Slide bolts E are here shown as the door-fastening means, and of course they can be duplicated on the door-memberA, though not here shown.

An astragal or Weatherstrip 10is mount-. ed on hinges 11 on the door-member B and.

covers the crack or slot 4 when thedoorway is closed by the door-members, but whenthe door-member B is opened, the springs 12, of the hingesll, swing the astr'agalto thelpositions shown in Fig. hwhere it is out of the path of the doormember A, so the latter can be opened and closed without interference injuring the latter..

i with the astragal, andv without danger of An actuating device such as shown in Figs.

5 and 6, when assembled, is mounted on the upper beam of the door-frame, and a si1nilar device is mounted onthe lower beainor door-sill, an opening 13 being provided in the threshold 14 to receive this lower actu ator, so the top of the latter is, substantially even with the top of the threshold. The v opening 13 also provides a clearance for the astragal to move into and out of engagement with the lower actuator.

. The actuating devices, or actuators, are

relation to the astragal.

indicated at 15, in their entirety, and will now be described in detail as follows:

A lower casing-member 16 and an upper casing member 17 are united by a bolt or fasteningniember 18, and provided with screwholes ihru which screws 19 may extend for holding them in place on the door-frame. A cam or pushing member 20 is provided with an elongated opening 21 thru whichthe securing member 18 extends forpermitting a limited sliding movement of the member 20 while securing it in the casing and in proper The pushing member has an arcuate or concave cam-face 22 against which an end portion of the astragal strikes when the door-member B is swung to its closing position, as illustrated by the broken lines in Fig. 4-. As the'door-member.

B-is forced to its fully closed position, the cam-face 22 automatically turns it against the pressure of its springs 12 until its weather-excluding surface lies flat against themner edges of the door-members,provided the member A is also closed, and is pushed thereagainst by springs which are suitably held within the casing. The pressure of these springs also serves to hold the doormembe rs pressed against their fastening means so they will not rattle as the wind blows against them.- Moreover, even if considerablewear should result from long use. of this device,

the spring-pressed device 15 will compensate for such wear, so the astragal will alwaysbe caused to eilectively close the crack between the door-members In the modified form of device shown in Fig. 7, the parts 16a and 20a may be cheaply and easily formed of blanks of sheet metal,

. and the same is true of the cover (not shown).

The springs 23a may have their ends seated around bosses 15b and 20b iormed by punch-' ing and depressing the side opposite thereto.

A rubber weather-strip 24 is shown in" Figs. 2 and 3, for closing the opening at the bottom of the door, and if desirable, this can be wide enough to cover the lower aetuator 15 or 15a; but I do not claim this as essential or a part of my invention, except in a broad'sense. Of course the free end of the strip 24 will yield to the weather strip or astragal 10 when'movin into the weatherexcluding position.

Although I have described this form of my invention specifically, I have no intention of limiting my patent protection to these exact details of construction and arrangement, for the inventionis susceptible of 1111-, merous changes within the scope of the 1nventive ideas. as implied and claimed. v The ends of the astragal may be provided with any suitable kind of ferrule or band 25 of metal or other suitable material to contact with the cam-faces and withstand wear while rubbing against the cam-faces, and the fer 1.
