WEATHER STRIP.

` Application krfiled December 2, 192.5. Serial No. 72,799,

This invention aims i to `provide novel means for mounting a weather strip onthe lower portion of a door, and for moving the weather strip downwardly, to cooperate with the threshold, when the kdoor is closed.

It is within the province ofthe disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains.

lith the above and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being` understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

In the drawings :e

Figure 1 shows in elevation, a device constructed in accordance with the invention, assembled with the door;Y

Figure 2 is an elevation showing the inner surface of the support and attendant parts:

Figure 3 is a section on the line 3 3 of Figure 2;

Figure 4 is a section on the line 4 4 of Figure 1;

Figure 5 is a detail enlarged fromFigure 2.

The numeral V1 marks a frame, such as a door frame, whereunto a closure orl door 2 is hinged at 3 for horizontal swinging movement, the threshold being marked by the numeral 30.

The device forming the subject matter of this application includes a support 4, in the form of a strip, held by securing elements 5 on the door 2 at the lower end thereof. A

packing ribbon 6, which may be made of rubber, is let into the inner side of the support 4 at the upper edge thereof, and, cooperating with the door 2, affords a tight closure which prevents water from finding its way downwardly between the support 4 and the door 2. At its inner surface, the.

reciprocation in the hearings 8, and the bearings extend about theplunger 11 yfar enough to hold the plunger in place. An adjustable head 12, such as a nut, is mounted on the onterend of the plunger 11 and is located inthe groove.- A compression spring'14 surrounds a` portion of the plunger 11, one end ofthe spring 14 abutting against the head 12 and the `other end ofthe spring abutting Vagainst one ofthe b'earingsjS, within the groove 7. An adjustable operating member 15, such as a screw, is

threaded into one vertical portion of the door frame 1 and is adapt-ed to engage the outer end of the plunger 11, when the door 2 is closed. In the lowerredge of the support 4 there is a recess 16.` vA weather-strip 17 mounted for vertical sliding movement in the recess 16and is supplied at its lower end with a lip 18, preferably made of felt,

vand adapted to cooperate with the threshold 30, if a threshold is used. There are notches 19 in the inner surface of the support 4. The notches 19 communicate with -the recess 16 and with the longitudinal groove 7. In the notches 19 are located bell crank levers 2O including.longitudinallyeX- tended arms, and transverse arms. The bell crank levers 20 are fulcrumed at 21 on the support. The transverse upstanding arms of the bell crank levers 20 are pivoted at 22 to the plunger 11. arms of the bell crank levers 20 are pivoted at 23 tothe upper endsof upstanding armsV 24 secured to the weather strip 17.

If desired, the door frame 1 may carry weather strips 25 adapted to cooperate withV the door 2, aboutv its entire periphery, eX- cepting the bottom of the door. The weather strips 25, in addition to the mechanism shown in Figure 2, close the space entirely about the door, and prevent the entrance of air. i Y 'y When the door 2 is closed, the operating member or screw 15 engages the end of the plunger 11 and moves the plunger to the right in Figure 2. When the plunger moves to the right. the bell crank levers 2O are operated, and lower the other strip 17 into engagement with the threshold 30. The operating member or screw 15 may be threaded inwardly and outwardly iii the door frame 1, so as to cooperate properly with the plunger 11 and thereby to cause the weather strip 17 to be lowered the de= sired amount, when the door is closed.

The longitudinal When the door is opened, the spring 14 reacts, and raises the Weather strip 17, by means of the plunger ll and .the bell crank levers 20, until the upper edgeV of the Weather strip `17 abuts against the support 4, at the upper end of the recess 16.

What is claimed is:

A device of the class described, comprising a support which is provided with a. lontfudinally extended groove, bell cranks fulcrumed intermediate their `ends on the support, loop shaped bearings in `the groove, a rod slida-ble in the Ebearings in spaced relation tothe Walls of the groove, 'a coinpression spring through which the rod extends, ythe spring abutting against one of the bearings, a weather ystrip mounted to slide :on ith'e support, the bell cranks being ings, the bearings being supplied With oppositely extended Wings which are secured `to the supper-.t pn opposite sides of the groove, the bell cranks forming the sole connecting `means between the Weather Strip and the trod, and `the nut being independent of .said means, the `bearings ibeing'restnicted at .their outer sides, to hold the nod :for

sliding movement jin the hearings.

In atestixnony that I rclaim the foregoing as my own, I have hereto affixed by :signai ture.

FRANK J. BOE-HLER.
