Application filed June 23, 1913. Serial at. 775,406.

To all whom it may concern:

Be it known that l, HENRY BAUER, a citizen of the United States, falo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Weather-Strips for Doors, of which the following is a specification.

My invention relates to weather strips for doors, and more particularly to that type in which. the strip proper moves automatically in contact with the floor upon closing the door to which it is applied.

The invention has for its object the provision of a weather strip of the type mentioned which is simple inconstruction, inexpensive and durable and in which projecting parts are dispensed with so that there is no liability of clothing being caught in passing through the door opening.

To this end the invention consists in the novel features of construction and in the combination and arrangement of parts to be hereinafter described and more particularly pointed out in the appended claims.

In the drawing in which like-numerals of reference refer to like parts, Figure 1 is an elevation of the lower portion of a door and the wall adjoining, the lower end of the door and a part of the door casing being broken away to illustrate the invention;

v the door being shown closed with the end of the door. Fig. 6 is a detached perspective view of the i y such point.

actuator.

The reference numeral 7 designates a wall, 8 the door and 9 the door-jamb to which the door is hinged. The door is provided with a longitudinal groove or recess 10 at its lower edge which has that endadjacent the unhinged vertical edge of the door closed, as at 11, the wall of the groove or recess at said end bein inclined so that suflicient material of the adoor remains to assure durability and strength at The opposite end of said groove or reces 12, to allow freedom in, action of an, aotu residing at Buf'.

sj. is increased in depth, as at s 14 designates two guide members which are fitted into the groove or recess 10 at points between its ends, said guide members being spaced apart and each being of channel shape to provide an inner wall 15 which bears against the inner wall of said groove or recess and side walls 16 which lie against the side walls of said. groove or recess.

Each of these guide members has also opposite lateral webs or extensions 17 which bear against the lower edge of the door, being preferably recessed therein and secured by screws. These guide members, by reason of their construction and manner of securing them to the door can be made of light sheet metal, and the side walls 16 of each are provided with alined obliquely-disposed guide slots 18 formed by slitting the metal and bending webs 19 outwardly therefrom, which webs are ranged along the upper edges of the slots and serve as hearing pieces which provide extended contact faces.

The weather strip proper is designated by the reference numeral 20 and consists of a longitudinal wooden or other suitable bodyportion 21 of a size in cross section to freely fit into and move within the groove or recess 10 and within the guide members 14: and of a length to extend almost from one vertical edge of the door to the other. This strip is grooved along its lower edge to receive a yielding contact element 22 of felt or any other suitable material, said contact element pro ecting beyond the lower edge of said strip and adapted to be' brought into contact with the floor when the door is closed'so as to close the space between the two, as clearly shown in Fig. 1.-

The end of the weather strip proper adjacent the unhinged vertical edge of the door is inclined, as at 23, to correspond to the inclined wall of the groove or recess 10 at that point and preferably bears against said inclined wall, and attention is directed to the fact that the inclination of the wall of said groove or recess and that of said strip is at the same angle as the guide slots 18.

Passing through the weather strip are pins 2 1- which project from opposite sides thereof and enter the guide slots 18 in the guide-members 14, said pins being adapted to move in contact with the webs 19 of said members. By exerting pressure lengthwise on.- the Weatherstrip in the direction 9 t e guided by its inclined end and the pins 24.

arrow in Fig. 2, it is moved toward the unhinged vertical edge of the door and also toward the floor, a lengthwise movement with a component downward movement is therefore obtained, due to the strip being The power to actuate the weather strip proper is obtained through theactuator 13 which is slidable in the enlarged portion 12 of the groove or recess 10, said actuator comprising a yoke or frame 26 having a longitudinal member 27, parallel arms 28 depend-.

ing from opposite ends of member 27 and an actuator member 29 inclined in opposite direction to the slots in the guide members 14, said actuator member entering a similarly inclined slot 30 in the weather strip 20. To increase the durability of the device I preferably provide a metallic member 31' in which the slot 30 referred to is formed, said member being recessed into the body por tion of the weather strip and secured thereto by screws or otherwise.

Extending through the arms 28 of the actuator yoke or frame is a rod 32, said rod being threadingly engaged with said arms 7 so that it may be adjusted therein, for a V edge of the door and closing the inner end 35. i I

of the groove or recess. 10.

Secured to the door j amb 9 is a metal wear plate 37, which is desirable in use but not necessary and the rear end of the actuator rod 32 is adapted to bear against said wear plate, or in the absence of the latter, against the jamb proper, which the wear plate may i be consideredpart of when used.

Interposed between the shoulder 38,

formed bytheincreased depth of the groove or recess 10, and'the forward arm' 33 of the actuator yoke or frame is a spiral spring 39 which surrounds the forward portion of the actuator rod 32 and serves to force and hold said rod and the yoke or. frame carried thereby in its rearmost position with the rear end projecting or tending to project j beyond the outer face of the guide plate 36, depending on whether the door is open or closed. By reason of the connection of the actuator with the weather strip the latter is drawn rearward with the actuator and moves upward when the actuator is in its rearward position, which position it is allowedvto assume when the rear projecting end of the actuator rod 32 finds no obstruction to its movement, such as the door j amb,

and since" in opening the door the hinged edge thereof moves away from the j amb and out of opposition thereto, saidirod is forced outward b the spring 39. When, however,

the door is closed, the hinged edge thereof is swung toward and in opposed relation to the door jamb, which causes the actuator to move forward against the counteracting efforts of spring 39, and by reason of the actuator member 29 being entered in the slot 30 in the weather strip, the latter is caused to move forward and downward, thereby closing the space between the lower edge of the door and the floor. During this action the actuator member 29 slides outwardly in slot 30 and in contact with the lower wall of said slot, while when the actuator moves rearwardly, member 29 thereof slides inwardly in said slot and in contact with the upper wall thereof.

If it is found that the door cannot easily close for the reason that the weather strip has too soon come in contact with the floor, the actuator rod 32 may be adjusted in its yoke or frame to diminish the length of projection beyond the hinged edge of the door, and if, when the door is shut, it is found that the space between the lower edge of the door and the fioor is not fully closed, said actuator rod may be adjusted to increase the extent of projection necessary. In this manner, the weather strip is adjusted for wear and also for diflerent sizes of spaces between doors and floors. In order to effect an adjustment of the actuator rod it is only necessary to revolve the same to the right or left within the actuator yoke or frame, as may be required.

I have herein resorted to the use of the expressions rearwardly and forwardly and the like as a convenient manner of expressing direction relative to the hinged and unhinged vertical edges of the door, it being my intention to consider the unhinged vertical edge of door the forward edge and the hin ed edge of the rear edge.
