The present invention relates to improvements in weather strips and more particularly to weather strips for attachment on the bottoms of doors.

One of the important objects of the present invention is'to provide'a weather strip which will automatically close the space between the bottom of the door and the floor or sill to exclude air, rain, snow and the like.

Another important object of the invention is to provide a weather strip that will move downwardly into an operative position when the door is in a closed position and into a raised inoperative position when the door is in an open position.

Another object is to provide a weather strip of the above mentioned character that will .be entirely automatic in its operation," the same being of such construction as to per- ZQ mit the attachmentther-eof'to the bottom of a door without necessitating any material alterations. I r l Another object is to provide a weather strip of the above mentioned character which is simple in construction, inexpensive, strong and durable and further well adapted to the purpose for which it is designed.

Other objects and advantages of the invention will become apparent during the course of the following description when taken in connection with the accompanying drawings. r

Figure 11 is a fragmentary detail View partly in section and partly in elevation for more clearly showing the manner of securing the roller to the movable plate at one end ofthe device.

- In the drawings wherein for the'purpose of illustration is shown the preferred rem bodi'rnent of my invention, the numeral 1 designates the bottom portion of a door, the

side ofthe door frame adjacent which the free vertical edge is adapted to be" disposed within a closed position being shown at 2 while the floor or sill is indicated at 3.

The doorl is preferably cut away at its bottom for the entire length thereof and secured to the bottom edge of the door are the parallel spaced'wooden bars 4, a metallic plate 5 being interposed'between the upper faces of the bars 4 and the bottom face of the door landthe securing means 6 extends upwardly through the bars and through the plate 5.

The lower edge portion of the door 1 is formedat spaced intervals with the verticall disposed pockets 7 and the plate 5 is formed with suitable openings 8 that register with the respective pockets? for a purpose to bepresently described. v V r r The plate 5 is of the same width and length as the lower-edge portion of the door 1, while the wooden bars 4 have their outer side faces lying flush with the respective side-faces of.

the door as indicated'very clearly in 'Fig ure2. i e

Longitudinally extending metallic strips 9.

the bottom faces of the respective wooden bars so that the inner edge portions of these metallic strips project inwardly beyond the inner side faces of the wooden bar, and the inwardly projecting portions of the metallic strips constitute supporting ledges, the purpose of which will also be presently described. The securing means for the wooden bars and the plate 5 also extend through the metallic strips 9 as is more clearly shown in Figure 4.

Extending vertically through the ledges 10 and the adjacent portions of the plate 5 are the pins 12, the same being arranged in pairs. A plate 11 is disposed between the spaced bars 4 and is provided with openings to accommodate the respective pins 12, said plate 11 being adapted for vertical slidable movement on the pins, as will be hereinafter more fully described.

Carried by the bottom face of the vertically movable plate 11 and extending longitudinally thereof is the floor or sill engaging strip 13 that may be of'rubber, felt or other suitable material. This strip 13 is formed at spaced intervals with the cavities 14 in the bottom face thereof to accommodate the headed lower ends of vertically disposed rods 15 that extend upwardly through the central portions of the vertically movable plate 11 as well as through the stationary plate 5 and I the upper ends of these rods extend into the respective pockets 7 formed in the lower edge portion of the door 1.

An ,expansible coil spring 16 encircles the upper portion of each rod for disposition between the plate 5 and the headed upper end of the rod for normally urging the vertically movable plate 11 upwardly.

An elongated plate 17 is disposed between the spaced bars'4 for disposition directly beneath the'plate 5 and the rods 15 extend upwardly through the plate 17 This plate 17 is adapted for longitudinal slidable movement and is formed with the longitudinally extending slots 18 to accommodate the pins 12 as well as the vertically movable rods 15 respectively and in Figure 8 of the drawings, there is shown a. portion of this sliding plate.

Upper and lower bracket forming plates 19 and 20 are secured at their inner ends to the upper and lower faces of the forward end portions of the plate 17 by any appropriate fastening means such as is shown at 21 with reference more particularly to Fig ure 11 of the drawings.

The outer end portion of the lower plate like bracket 20 is offset and a vertical pin 22 extends through the outer end portions of the plates 19 and 20 to providea support for the horizontally disposed roller 23, the purpose of which will be presently described.

The forward end portion of the stationary plate 5 is cut out as indicated at '24 with reference more particularly to Figure 7 to accommodate the bracket and the roller carried thereby. This plate 17 is normally urged forwardly in a direction toward the vertical free edge of the door 1 through the medium of the expansible coil spring 24 and is arranged within a longitudinally extending recess 25 formed in the lower edge of the door 1. The spring is furthermore disposed through a longitudinally extending slot 26 formed in the stationary plate 5 and a slot 27 is formed in the slidable plate 17 also to accommodate the spring 24. Upon referring to Figure 1 of the drawings it will be observed that the slot 27 formed in the slidable plate 17 is shorter than the slot 26 so that when the door is swung to open position, the spring 24 will move the plate 17 in a forward direction as will also be hereinafter more fully described.

A series of substantially arcuate shaped strips 28 are struck up from the vertically movable plate 11 and the same are arranged in pairs for cooperation with similar arcuate shaped strips 29 that are struck out from the slidable plate 17 and are disposed downwardly. The arcuate shaped members 28 and 29 cooperate to maintain the plate member 11 lowered to hold the strip 13 in engagement with the floor or sill as shown in Figure 1.

The operation of my weather strip may be briefly stated as follows: l/Vhen the door 1 is in a closed position, the parts are arranged in the manner as shown in Figure 1, and it will be observed that the plate 17'is in its rearward most moved position so that the bowed strips 28 engage with the respective superposed bowed strip 29 whereby the strips or pad 19 is held in engagement with the floor or sill, thus completely closing the space between the bottom of the door and the floor or sill to exclude air, rain or snow.

As soon as the door 1 is swung to an open position, the roller 23 is released from engagement with the j amb 2 and immediately the spring 24 will urge the plate 17 forwardly and this will result in the arcuate members 29 being moved out of engagement and out of the path of movement of the underlying arcuate member 28 so that the springs 16 will move the rods 15 upwardly into the pockets 7, thus raising the strip 13 and the plate 11 to which the strip 13 is secured to the position shown in Figure 10.

When the door is again moved to a closed position, the roller 23 will strike the jamb 2 and will urge the plate 17 rearwardly against the tension of the spring 24 to again move the arcuate members 29 into engagement with the crown portions of the respective underlying arcuate member 28 thus lower-' ing the plate 11 and the strip 13 attached thereto so that said strip 13' will be brought into engagement with the floor or sill.

It will thus be seen from the foregoing description that I have provided a weather strip that will be entirely automatic in its operation, the same being of such construction as to permit the attachment of the weatherstrip to the bottom of a door without necessitating much alteration. Furthermore, my weather strip will at all times be positive and eflicient in its operation, and the parts can be readily and easily assembled or disassemlVhile I have shown the preferred embodiment of my invention it is to be understood that minor changes in the sizef'shape and arrangement of parts may be resorted to without departing from the spirit of the invention and the scope of the appended claims.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent is 1.
