JOHN B. SMITH, OF ROYAL OAK, MICHIGAN.

WEATHER-STRIP FOR DOORS AND WINDOWS.

Specification of Letters Patent.

Patented Dec. 3, 1907.

Application filed December Il, 1906. Serial No. 347.353.

T0 all whom it may concern: Be it known that I, JOHN B. SMITH, a citizen of the United States, residing at Royal Oak, in the county of Oakland and State of Michigan, have invented certain new and useful Improvements in Weather-Strips for Doors and Windows, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to improvements in weather strips, and has for its primary object the provision of a strip which, although capable of other uses, is particularly adapted` for the bottom of doors.

A convenient embodiment of the invention embraces two metallic members hinged together, a spring or springs for normally maintaining them in alinement, a flexible strip, such as felt, carried at one edge of one of the metallic members to project outwardly therefrom, and instrumentalities for depressing the felted edge of the strip into forced contact with the door sill when the door is closed, to seal the space therebetween, the strip being preferably mounted within a groove in the bottom of the door whereby to be substantially hidden from view when the door is open, and the ordinary neat, trim appearance of the door preserved.

Novel characteristics of the invention include the provision of two members to constitute a hinge therebetween, the clamping means for 4securing the felt strip in place at the edge of the relatively free member of the strip, and the special formation of the relatively fixed member thereof to brace the corner and flange ofthe door adjacent thereto formed by the grooving out of the bottom of the door to accommodate the strip.

The details in the construction and arrangement of the several parts of the device will be apparent from the detailed description hereinafter contained, when read in connection with the accompanying drawings forming a part hereof and wherein the before mentioned embodiment of the invention is illustrated;

In the drawings: Figure l is a perspective view of the bottom portion of a door showing the strip attached thereto, Fig. 2 is a cross sectional view of the same in closed position, Figs. 3 and 4 are detail sectional views showing the devices at opposite sides of the door formed for depressing the strip` away from its elevated position and against the tension of the elevating springs, and Fig. 5 is a bottom view of the door.

Referring more specifically to the drawings, wherein like reference characters designate corresponding parts in the several views, A represents a portion of an ordinary door frame, B the sill thereof and C the hinged door. The bottom of the door is grooved out to form a space D for the reception of the strip, said space being bordered by depending flanges E and F, whereby to hide the strip from view when the door is open as will presently appear. The strip is composed of two metallic members G and H, the former constituting what I will term the relatively fixed member, and the latter the relatively free member. The member G constitutes the means for securing the strip in place, it being provided with a series of apertures for the reception of securing screws J.

It will be noted that the member G lies flat against the base of the groove heretofore referred to and also that its edge is turned downwardly as at K to fit the corner of the groove immediately adjacent thereto and to abut the flange E on the door, in a manner to strengthen the same against cracking or breakage incident to impact of the foot or other objects against the flange when the door is closed. The members G and H are hinged together, as indicated at K and they are held in alinement within the groove of the door by means of springs L wound upon the pivot rod or hinge and having their ends extending in opposite directions to impinge against the lower surfaces of the members G and H respectively, whereby the spring eX- erts a constant upward pressure upon the relatively free member H sufficient to effectually retain the same substantially in or above the plane of the lower edge of the door, except when forced downward by means of cooperating devices on the door frame. These coperating devices comprise a wedgeshaped member-M mounted upon the hinge side of the frame, adapted to slip into the space N intermediate the upper surface of the stri member H and the base of the groove Fig. 8), and an inclined member O (Fig. 4) secured to the opposite side of the frame arranged to project into the cut away portion I of the door and engage the upper surface of the opposite end of the member H of the strip as the door is closed, whereby both ends of the strip are forcibly pressed down into engagement with the `door sill (Fig. 2).

The packing strip P', which as hereinbefore suggested, may be of any suitable material. such as felt, is iirmly held in place at the edge o f the strip member H, by means of a clamping plate vQ secured to the member H and having an u turned edge R entering the groove S forme by curving the edge of the member H downwardly, as at T. The clamping plate being firmly secured to the member H, as stated, the felt is firmly compressed within the groove or elbow of the sald member H and is practically secured against accidental withdrawal therefrom. Another highly important feature of this particular arrangement, is that the packing strip is forced edgewise against the sill, the curved overhanging edge of the member H. pressing directly downward thereupon when depressed by the devices M and O. Further, when the member H is in its elevated position within the groove, the downwardly curved edge of said member H nts snugly against the flange F and serves to reinforce and strengthen the same. By this operation a better contact between the strip and the sill is secured than would be the case with the felt presented sidewise tothe sill rather than edgewise, as stated.

It will b e observed that either of the flanges E and F of the door may be omitted, or that both of them may be omitted and the strip applied directly to the bottom of the door when there is sufficient space to accommodate the strip, the turned down edge of the fixed member G of the strip in such instance being flattened out or omitted. Thus it will be appreciated that the strip is one which will be capable of ready application to the door, it simply being necessary to screw the same in place upon the bottom of the door, previously grooving the same wherever it may be desired or found necessary.

vI claim 1. In combination with two members, one movable relative to the other, one of said members'being recessed, a weather strip for sealing the space between said members comprising a sealing part, and a securing part fastened in said recess, said securing part having a reinforcing fiange for the corner portion of said recessed member.

In a weather strip of the character described, a supporting member having a downwardly turned free edge, means for pivotally supporting said member in place, means for moving said member outwardly and a felt strip secured beneath said downwardly turned portion of said supporting member and projecting outwardly at an angle relative to said member whereby said downwardly turned portion will back said felt strip and force the same into edgewise contact With the member against which it abuts, when said supporting member is moved outn wardly.

3. In combination with two members, one movable relative to the other, one of said members being provided with a recess, a weather strip for sealing the space between said members including a movable sealing part adapted to rest within said recess and to be forced outwardly therefrom, said sealing part being provided with a flange serving as a reinforcing means for a corner of said recessed member, when the sealing part rests Within the recess.

4. In a combination with a door cut away to form a recess at its bottom, and its sill, a weather strip comprising a movable supporting member adapted to rest within the recess and to be moved outwardly therefrom, saidv supporting member having a portion bent at an angle to the plane of the body portion thereof, means for forcing the supporting member outwardly and a felt strip secured beneath said bent portion of the supporting member and projecting outwardly at an angle relative to the supporting member, whereby said bent portion w ill back said felt strip and force the same into edge ise contact with the member against which it abuts, when said supporting member is moved outwardly.

5. in a weather strip of the character described a supporting member having a curved free edge, means for pivotally supporting said member in place, means for moving said member outwardly, a clamping plate secured to the supporting member and having an upturned edge entering the groove formed by the curved edge of the supporting member, and a felt strip inserted between said members and held in place by the biting action of the intertting portions of the clamping plate and supporting member.

In testimony whereof I aiiiX my signature in presence of two witnesses.

JOHN B. SMITH.
