WEATHER STRIP.

Application lied May 21, 1924. Serial No. 714,950.

The .present invention lrelates to improvements in weather strips and has for its primary objectfthe provision of a self or auto-A matically operated device of this character instantly'clear itself from the floor or co'acting surface the moment the door is swung from a closed position and which will act, the moment the door is fully closed, to effect a waterproof seal between the oor or co-acting surface and the lower edge of the door;

Another object of the invention is to provide a device of this character which coeacts directly withl a floor surface without use of the customary sill and which, through the'provision of novel features lof construction will permit the door to move'freely at all times. A 1 Q Another object of the invention is to provide a device of this character' which simple of construction, strong and durable, inexpensive of manufacture and reliableof operation.

Another object of tle invention is to pro- 7 vide a device of this character whose `working parts are readily accessible'for the purposel of repair or lubrication.

The invention consists in the novel con` struction and. combination of the several parts, as will be hereinafter fully set forth, and pointed out lin the claim.

ln the drawings Figure 1 is a perspective view of a pbrtion -of la door and its frame showing an application of my invention thereto;

Figure 2 is a section on line Tlf-TT of Figure 1 Figure. 3 the hinge side of the door showing tlie strip in co-a'cting relation to the stop on the jamb of the door; y

-Figure Llis a horizontal section on line lV-IV of Figure- 2;

' Figure 5 is a vertical section through the movable strip member on the line V-`V of Figure L i;'and

Figure 6 is a vertical section through a portion of a door showing a slightly modified form of the invention.

lVhile my present invention is particularlv designed for use in swinging doors of the i rkind illustrated, itsuse is found advantageous upon what are knownin the artas French doors and windows and swinging easements. l f

For the purpose of illustration, (A) repis a-horizontal section through i resents a swinging door, (B) the jamb, and (C) the stop, the latter located -near the hinge (D) as shown in Figure 3, and same is provided with a morticed bracket (5) carrying an anti-frictionroller (6) whichextends slightlyi beyond the exposed broadl surface of the stop. The purpose of this roller will be described presently.

At (7) is indicated a casing, the 'same formed preferably of a single strip of metal bent in U-form to provide parallel sidewalls (8)v and (9) and a connecting topwall (10). This casing has its side walls formed with alined apertures (11) and passing therethrough is a bushing (12). Two of these bushings are shown in the present'example and same are in horizontal alinement. Passing through these bushings are fastening screws (13) or equivalent devices whereby the device can be quickly attached to the door. Extending around the bushings (12) are anti-friction sleeves (14).

The casinoA (7) is secured to one side of thedoor (A. so that the edges of the walls l(8) and (9) come Hush with the lower edge of the door. A housing strip ,(15) is secured at (16) to one side of the door so as to extend over the casing (7).- This housing strip-'is freely detachable in order that access may be had to the casingand the work# ing parts therewithin. y The screws (13)v also pass through the lower'portions of the said housing strip, as shown inFigure 2.

Located/between the parallel side walls (8) and (9) of the casing (7) is a strip carrying member (17 at its edges to provide Va channel (18) for a weather strip which has a reduced side portion 19 of a size to be frictionally held Within the channel and an enlarged rounded Thisy is formed of a single'.` piece of sheet metal bent on itself and formed sid'e portion 20 disposed outwardly beyond themember 17. This strip may be formed of rubber, felt or any other elastic or pliable material and the base of the strip isl approximately medially thereof. These slots accommodatey the anti-friction sleeves (14), as clearly shown in Figure 4.

coiled s ring (22) has. one end attached at (23) to't e strip carrying member (17 )l The spring extends up through a slot (24) in the casing (7 andthe opposite end of the spring is connected at (25) to said casing so as to normally pull upward on the member (17 This retracts the stripV (20) into the space between the side walls of the casing (7 and clears/thestrip from the floor surface.

lAt this time it shall be assumed that the door (A) is open and that incident to the upward pull upon the member 17 ),.one end of the latter is project-ed beyond the casing (7) as" at (26), Figure 4. The protruding end '(26) of the member( 17) is adapted to co-act' with the anti-friction lroller (6) on' The co-action of the parts the stop (C).l

f occurs as the door is moved to its closed position, the roller, (6) bearing against the end (26) of the member (17) so as-to force the latter downward against the act-ion of the Y spring (22). In so doing thebroad lower end of the strip (20) is advanced into yielding engagement with the floor surface so as to seal the joint bet-weensaid surface and the lower edge of the Jdoor.

The invention suggests an assemblage of parts .that `can be quickly put together or Itaken apart as the occasion demands; The

entire device can be attached to a /door with-` out requiring any costly -alterations in the construction thereof or rendering the door unsightly The construction of. the device isalso such that its working parts'are. protected against injury incident to accidental lkicking of the door.4

In the modification shown in Figure 6 I morticethe lower edge of the door as at (E). The casing (7) is extended into the mortice and bolted to the door as at(27).

In this manner all parts -of the device are concealed and the elastic strip (20) extends down from the door in line with the vertical j center thereof.

The outer wall (9) of the casing is provided with an oil hole (28) above each of fthe anti-friction sleeves (14). In this manner the working parts can be lubricated when the housing strip (15) is removed. 1

The construction of the strip carrying "when desired.

, purpose setforth.

member (17) is such that its free lower edges can 'be pinched againstthe restricted end of the strip (20) to hold .the same normally in place and at the same time permit the strip to be removed and replaced by a new one It shall be understood that alterations andchanges in the construction of the device can be made within the scope ofthe hereto ap` cover the casing, means for securing the casing and housing strip to the door, an oblong carrying member disposedl sidewise between theivalls of the casing and obliquely movable therein, said carrying member being formed of a metallic blank bent upon itself longitudinally at its middle portion and have ing the marginal portions of its longitudinal sides'bent outwardly and inwardly to provide a flared socket, a weather strip of flexible material having a reduced side portion disposed within the socket and frictionally held by the walls thereof, and an enlarged rounded side portion'locate'd outwardly be,

yond the socket, said carrying member further having sloped recesses opening at one end through the upper side of the member and disposed so as to receive the means for securing the housing Istrip and casing to the door and thereby coact with the said secur ing means to permit of oblique movement of the strip carrying' member, a spring connected to the stripcarrying member and the casing for moving the said member in one direction so as to effect the projection of one(y 4 end of the member beyond one end of the casing when the door is opened, and means Aadapted to 'be connected to the .door frame and disposed so as to'engage the projecting end of the strip CLAUDEL. rom).
