WEATHER-STRIP FOB. DOORS.

T0 allwhom it may concern Beitknown that I, JAMns R. DUPEN, a citizen of the United States, residing at Chico, inthecounty of Butte and State of California, have invented certain new and useful Improvements in'lVeather Strips for Doors; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to that class of devices intended to form a weather tight connection between the lower ends'of doorsand the sills of the door frames. I am aware that numerous previous devices have been provided for this purpose, but it is my intention to devise a novel type ofweatherstrip which will be automatically applied to use whenfthe door is closed, and raised from operative position when said door is opened, this insuring that rugs and carpets on the floor shall not interfere with opening of the door.

lVit-h the foregoing general object in view, the invention resides in the novel features of construction and unique combination of parts to be hereinafter fully idescribed and claimed, the descriptive matter being supplemented by the accompanying drawings which form a part of this specification and in which:

Figure 1 is a vertical longitudinal section showing theinvention' applied to a door, the latter being shown almostentirely closed;

Fig. 2 is a View similar to Fig. 1 but illustrating the door in completely closed position;

Fig. 3 is a detail vertical longitudinal section showing more particularly the ac tion of the dog as the door is opened;

Fig. 4 is a vertical transverse section on the plane of the line 41 of Fig. 2; and

Fig. 5 is a similar view on the plane designated by the line 55 of Fig. 2.

111 the drawings above briefly described, the numeral 1 has reference to a common type of door which is hinged to the door frame 2, this frame having the usual sill 3 between which and the door, the present invention is employed for establishing a weather tight connection. A fiat horizontal casing l is carried by the lower end of the door 1 and is preferably inset therein as shown most clearly in Figs. 4 and 5, said Specification of Letters Patent. Patented Apr, 16, Application filed June 21, 1917.

Serial No. 176,204.

casing preferably having an attaching plate which extends horizontally at 5 beneath the door, and then verticallyat 6 along theside thereofremote 'from'that at which the casing 1 is located. Screws or any other suitable fasteners are passed through the attaching plate and into the door 1 for securing the casing-in place. Although this attaching means is shown, however, it is to be understood that any suitable construction could well be employed for carrying out the same purposes.

Mounted within the casing at, is a hollow metallic weather strip 7 preferably having a strip of felt, leather or other suitable material 8 along its lower edge for contact with the sill 3, said strip 7 being carried by an arched spring 9 which is suspended bya shackle 10 from a lever 11 which is fulcrumed at 12 in the casing. A suitable spring 13 is secured at one end in the casing a and at its other end is connected to the lever 10 so that it normally exerts its tension to raise the Weatherstrip 7 out of ,engagement with the door sill, such raising action taking place automatically when the door is opened. By means of a rotatably mounted operating member 14, however, the lever 11 is so actuated as to automatically lower the weather strip when the door is closed, thus insuring that the binding strip 8 shall come in tightcontact withthe sill 3 to excludethe elements.

.The'cperating member 14 is preferably.

in the form of a star wheelwhose several points are positioned for operating the lever whenever said wheel is turned a predetermined amount. This turning action is imparted to the wheel 11 by a thrust device 15 which is carried by the door frame 2, or rather by a plate 16 which is secured to said frame. The device 15 includes a pivoted dog 17 whose nose 18 rises from the pivoted end of said dog, the tail of the latter, however, normally lying horizontally upon the support 19 to which the dog is pivoted, whereby it serves to return the device to its initial position after it has once been dis placed as will be hereinafter described.

By the arrangement of parts so far described, whenever the door is opened, one of the prongs of the star wheel 14:, which has been previously resting on the tail of the dog 17, will come in contact with the nose 18 of said dog so that the latter is rocked or tilted to the position depicted in Fig. 8, said dog therefore offering no resistance to opening of the door. \Vhen the door is opened, the wheel 14E assumes an idle position, so that the tension of the spring 13 is exerted to automatically raise the Weather strip 7 thus insuring that it shall not contact with rugs or carpet or with the floor proper. When the door is closed, the nose 18 of the dog 17 contacts with one of the points of the star wheel 14 and this rocks the latter throughout approximately one-third of a revolution. This so actuates the lever 11 as to force downwardly on the spring 9, with the result that the weather strip 7 is projected from the lower side of the casing i into contact with the door sill 3. All of this operation takes place automatically and no attention whatever is required to maintain the device in proper working order.

Preferably used in connection with the features of construction above described, is a latch 20 which is pivoted within the casing 1 and coacts with a suitable stop 21 carried within the weather strip 7, so as to hold the latter in raised position while the door stands open. A push rod 22 is provided, however, for automatically releasing the latch 20 when the door is closed, said push rod being mounted slidably within the Weather strip 7 and having a suitable coil spring 23 for normally moving it to inoperative position. When the door is closed, however, a pin 24: which is carried by the plate 16 or by the frame proper, comes in contact with the outer end of the rod 22 and forces the latter inwardly, thereby automatically releasing the latch 20 so that the spring 9 may force the weather strip 7 downwardly when said spring is placed under tension by the lever 11, which latter is operated by the star wheel 14 in the manner above described.

said star wheel and resting on one of changes may be made without sacrificing the principal advantages.

I claim:

The combination of a weather strip mounted on the lower end of a hinged door, means for exerting a continual upward stress on said strip to raise the same, a triangular star wheel mounted on the door, at the hinged edge thereof, a lever carried by the door and having its resistance arm connected operatively with said weather strip, the power arm of said lever extending over the three sides of said wheel when the door stands open, and a stub on the door frame for striking the lower point of said star wheel when the door is closed and turning said wheel until the next point thereof raises the power arm of the lever and moves beyond dead center, the third point of said star wheel then contacting with the upper side of said stub to prevent further rotation of the wheel until the door is opened.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

JAMES R. DUPEN.
