e whom i m y cmmem Be it known that 1, lv pL Aiu Hana GREGORY G nna, a subject oft-he King of G e t B ta n, re idin a v1K lle s,P a y ney, in the State of New South VY alesQGonr monwealth of Australia, have invented oer-- tain new andiuselful Improvements in Draft Excluders of which thefollowing is a specification. v

Thi mpas e elates t ilipmv me s idra tt escl iders for dooil Q1 theglilze, of the type comprising a strip of wood, i11etal,.and other suitable material adapted to be movably attached to adoor or casement window adjacent the low-er edge *got the latter and which is lowered toor igaised from ,the floor or thebottein lintelwhen pressure is .imparted to the against the action vi p ngshen th d Qi w n ow i Closed and released avhen the or window .is opened. f j V V a My object has been :to provide a draft excluder of this char-actor which may be sold an article of inanuiiacture land which is capable of being readily fixed in position by any unskilled person which tl estrip is alwaysgin contaot withthe door or window so that ,no space is between for ingress of air; wherein the torraising the strip may be practically enclosed; in which vguii le slots are dispensed with; and in which the descent .or ascent ofthe strip is accelerated dowards thefinal or initial stage respectively. A dunther object of the invention ,is to provide an :article of the character referred to whichana-y be ;applied gl'zO either a righ or let ;,1.and op ningyd r, h c s may 3116. g V

The invention will hedescrihed -Wltl1 Jeterence to the accompanying drawings in which is illustrated a practical embodiment thereof. r

Figure 1 is a front elevation of the lower portion of a door having a draft excluder which embodies a preferred form of the invention fitted thereto, the draft excluder be ing shown in the raised position.

Figures 2 and 8 are partial side elevations on an enlarged scale showing a portion of my draft exclude): secured to a door, the strip being shown in the raised and lowered positions respectively.

Figure 4: is a perspective View of one of the springs,

Figure 5 is a sectional view, on an en largd scale on line 55, Figure l.

The same numerals indicate the same or corresponding parts. v i

8 is a strip of wood or other suitable mate rial provided with slots or recesses 9 in which are secured diagonally positioned pins 10 which are associated with a spring; hereinafter referred to. These pins are inclined atania ngle of about 7 0 tothe lower edge of the strip and, whilst tending to minimize friction with their associated springs, insure quick descent or the strip. .11 is'a spiing provided at or adjacent one of its ends with a pair oi aligned eyes or loops 12 through which is passed a nail or screw 13 to secure the device to a door or window, the position. of the eyes being such that the correct placing of the screws is facilitated. A'lJshapc portion formed in :the spring between the eyes 12. A further loop 14 is formed in -he spring 11 aboutmidway of its length to increase the resiliency of the spring. A suitable rubber or feltledging 15 may be secured tothe lower edge of the strip 8.

1-6 representsa door ;to which the device is shown as attached.

To attach thestrip'8fto a door 1 6 or [winhfdow the strip 8 is souplaced iat the lower edge'iof thedoor or window that one end slightly projects beyondthe hinged edge of the door or window, and a nail or screw 13 is passed through the respective eyesor loops :12and secured to the .door or window.

Assuming that the door or window to which the device is attached to be open, the

parts will he in the position-shown in Fig:

2. lLVhere the door or window is closed,=the

projectingendof the strip 8 contacts with the jainh of the door or the window casement and the strip 8 is thus shifted toward theopposite edge ofthe door. That end wall of each of the slots or recesses 9 which is nearest the hinged edge of the door will thus be caused to press against the rear end of its spring 11 and, since the opposite end of each of said springs is secured to the door by its screw 13, the latter end of the spring i can only rock on said screw. The pins 10 avill, therefore, be caused to ride down wardly between the U-shaped portions 17 of the springs and the screws or nails 18, thus causing the strip 8 to move downwardly quickly and. to'contact closely with the floor to exclude any dust or draft under the lower edge of the door 16.

hen the door or window is opened the rear ends of the springs 11 bearing against the rear ends of the slots or recesses 9 will shift the strip 8 in the opposite direction, thus causing the pins 10 to move upwardly through the U-shaped portion 17 of the spring and the screw or nail 13. It will be noted that, since the U-shaped portion 17 oi the springs straddles the pins 10, and since the eyes 12 at the ends of said U-shaped portion 17 are secured to the door by the screws or nails 13, said screws or nails also serve to secure the strip 8 to the door, and that the strip may be removed from the door by simply removing the screws or nails 13. Instead of forming a U-shaped portion 17 on the spring 11 between the eyes 12 to slide on the pin 10, I may form a loop between said eyes, in which case, it is necessary to remove the pin 10 before withdrawing the spring 11.

The slots or recesses 9 may have cover plates to prevent ingress of dust.

It is obvious that I may use more than two slots or recesses each fitted with a diagonal pin. The slots, however, must be so spaced that the strip will always be parallel to the I claim.

1. A strip for attachment to a door adjacent the lower edge of the latter with one end in engagement with the door jamb at the hinged edge of the door, said strip having a slot extending therethrough, a spring contained in said slot with one end in engagemcnt with a wall of said slot and tending to move said strip toward the hinged edge of the door, said spring having means to receive a hold-fast device for securing said spring and said strip to the door, and means mounted in said slot and associated with said spring and adapted to cause said strip to move beyond the lower edge of the door when the end of said strip bears against the door amb during the closing movement of the door.

2. A draft excluder for doors or the like comprising a strip for attachment to a door adjacent the lower edge of the latter with its lower edge adapted to project beyond the lower edge of the door and one of its ends adapted to project beyond the hinged edge of the door, said strip having a slot therethrough, a spring in said recess having one i of its ends engaging one wall of said recess and tending to move said strip longitudinally toward the hinged edge of the door and having its other end formed with a pair of aligned eyes to receive a hold-fast device for securing said spring and said strip to a door and with a loop between said eyes, and a pin extending diagonally of said slot between the loop and eyes of said spring, said pin adapted by engagement with said loop and with the hold-fast device extending through said eyes to cause the lower edge of said strip to move beyond the lower edge of the door when the strip is shifted longitudinally by engagement of its end with the door jamb during the closing movement of the door and to cause the lower edge of said strip to rise when the strip is shifted longitudinally in the opposite direction by said spring during the opening movement of the door.

3. A draft excluder for doors or the like comprising a strip for attachment to a door with one end in engagement with the doorjamb at the hing-ed edge of the door and having its lower edge movable beyond the lower edge of. the door, said strip having a plurality of slots therethrough, a spring in each of said slots having one of its ends in engagement with one end of its slot and tending to shift said strip toward the hinged edge of the door, said spring having means at its other end to receive a hold-fast device for securing said spring and said strip to the door, and means extending transversely of said slot at an inclination to the lower wall of the latter for engagement with said holdfast device, said means adapted by its cngagement with said hold-fast device to cause said strip to rise from the lower edge of the door when said strip is shifted lougitudinally in one direction by said spring during the opening movement of the door and to cause the lower edge of said strip to project beyond the lower edge of the door when said strip is shifted longitudinally in the opposite direction by engagement of the end thereof with the door jamb during the clos ing movement 01 the door.
