The rod 32 carrier plate 9 has a lower guide II, in the form is supplied at one end with a ball 33 slidably reof a rib, extending into the recess 8 of the door ceived in the guide I2 of the plate 9. On its op- 3. The carrier plate 9 is supplied, above the posite end, the rod 32 has a ball 34 received in a guide rib II, with an upper tubular guide I2, seat 35 formed in the end of, a slide 36. The slide 55 36 is mounted to reciprocate in the guide I1 of the plate I4. A roller 31 is journaled on the outer end of. the slide 35. The roller 31 is horizonl tally disposed. The slide 36 corresponds in cross 5 section to the guide I1, the slide cannot turn on its axis, and, consequently, the roller 31 keeps the horizontal position shown in Fig. 3. The roller 31 is adapted to ride along the inclined surface 22 of the arm 2| on the anchor plate 20, when the door 3 is closed. The slide 31 is provided with a shoulder 38 which, cooperating with the inner end of the guide I1, limits the movement of the operating member 3| to the right in Fig. 1.

Abutments 39, 43 and 4| are secured at 42 to the intermediate section 32 of the operating member 3|. The abutment 4S is an intermediate abutment. The abutment 39 is disposed between the abutment 4G and the slide 36. The abutment 4| is located between the abutment 4U and the tubular guide I2.

Raising and lowering members 43 are mounted movably on the rod 32, but keep a xed positio-n thereon. One of the raising and lowering members 43 engages the abutment 4|, under the action of a compression spring v45 surrounding the rod 32 and interposed between the abutment 4|! and the raising and lowering member under consideration. The other raising and lowering member 43 engages the abutment 39, under the action of a compression spring 46 engaged between the said abutment and a washer 41, the washer 41 abutting against the inner end o the slide 3S. A washer 48 is mounted on the rod 32 and engages the inner end of the guide I2. A compression spring 4S is mounted on the rod 32 and engages the abutment 4| and the washer 48. The raising and lowering members 43 eX- tend downwardly between the upstanding ilanges 2,8 of the body 24 of the wind check 23 and have inclined slots 44 wherein the rollers 30 on the body 24 of the wind check 23 operate.

When the door 3 is open, the spring 49 moves the operating member to the right and causes the roller 31 to outstand beyond the plate I4. As the operating member 3| is carried to the right, the slots 44 in the members 43, cooperating with the rollers 3l) on the wind check, to raise the wind check. When the door 3 is closed, the roller 31 on the operating member 3| rides along the inclined surface 22 of the fixed ramp 2|, the operating member 3| is carried to the left, and the slots 44 in the parts 43, cooperating with the rollers 30, carry down the wind check 23 and cause the weather strip 21 to close the space beneath the door 3. When the door 3 is closed, and when the operating member 3| moves to the left, the rod 32 can slide a little in the parts 43, the springs 45 and 45 being compressed, this construction avoids shocks, the springs acting as cushioning springs.

Although the member 23 has been called a wind check, it will of course serve to stop water, insects and sound from entering beneath the door 3. The part 23 is automatic, self-adjusting and exible in operation and will serve as an adequate closure for the space between the floor and the lower edge of the door. It adapts itself to structural irregularities in the door or in the floor, and is easily installed.

Having thus described the invention, what is claimed is:

1. In a device of the class described, rst and second carriers, means for mounting the carriers on opposite edges of a closure, a check, means for mounting the check for vertical movement; an operating member comprising a body, and a slide mounted for straight line movement on the first carrier and movable outwardly beyond the irst carrier for engagement with a closure frame; means for mounting the body for longitudinal sliding movement on the second carrier and for pivotal movement thereon, a pivotal connection between the body and the slide of the operating member, said pivotal connection and the pivotal mounting of the body on the second carrier avoiding a flexing of the operating member when the closure warps, interengaging parts on the check and on the body of the operating member, cooperating to lower the check when the operating member is moved inwardly, and spring means for moving the operating member outwardly, when the closure is opened, thereby to raise the check.

2. In a device of the class described, first and second carriers, means for mounting the carriers on opposite edges of, a closure, a check, means for mounting the check for vertical movement; an operating member comprising a body, and a slide mounted for straight line movement on the first carrier and movable outwardly beyond the rst carrier for engagement with a closure frame; means for mounting the body for longitudinal sliding movement on the second' to raise the check, and a compression spring interposed between the raising and lowering member and the slide, the last-specified spring acting as a cushion and as a means for holding the raising and lowering member yieldably engaged with the abutment.
