CHARLES A. PIKE, OF PAW PAW, MICHIGAN.

WEATHER-STRIP.

To all whom it may concern:

Be it'known that I, CHARLES A. PIKE, a citizen of the United States, residing at the village of Paw Paw, county of Van Buren, State of Michigan, have invented certain new and useful Improvements in WVeather-Strips, of which the following is a specification.

This invention relates to improvements in weather strips for doors.

The main objects of this invention are: first, to provide an improved weather strip for .doors by which the wear on the floor or door sill and on the weather strip is reduced to a minimum. Second, to provide an improved weather strip for doors adapted to form a very tight joint when the door is closed, and one which does not materially add to the power required to open or close the door. Third, to provide an improved weather strip for doors embodying the above features, which is automatically controlled by the opening and closing of the door, it being adapted to automatically open on the opening of the door and to automatically close on the closing of the door. Fourth, to provide an improved weather strip for doors embodying the above advantages which is a simple and economical structure and may be readily applied without in any way mutilating the door to which it is applied.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification.

The invention is clearly define d and pointed out in the claims.

A structure embodying the features of my invention is clearly illustrated in the accompanying drawing, forming a part of this speci fication, in which,

Figure 1 is a detail elevation of a structure embodying the features of my invention, the open position of the parts being indicated by dotted lines. It will be understood, however, that they do not assume this position while the door is closed. Fig. 2- is an enlarged detail section taken on a line corre sponding to line 22 of Fig. 1. Fig. 3 is a detail section through the levers 8, taken on I a line corresponding to line 38 of Fig. 1, showing the connection for the levers. Fig. 4 is a detail vertical section, taken on a line Specification of Letters Patent.

corresponding to line 4-4 of Fig. 1, showing 1details of the weather strip or plate-lifting ever.

In the drawing, the sectional views are taken looking in the direction of the little arrows at the ends of the section lines, and similar numerals of reference refer to similar parts throughout the several views.

Referring to the drawing, 1 represents the wall of a building 2 the door frame or casing; and 3 the floor or door sill. The door 4 is hung on suitable hinges, but as these form no part of this invention they are not here illustrated.

The weather strip or plate 5 is arranged across the bottom of the door, and secured thereto bythe screws 6 which are arranged in the vertical slots 7 in the plate. These screws also serve as supports for the levers S, which are pivotally mounted thereon. The levers 8 are pivotally connected at their outer ends as by the screws 9 to the plate. The inner ends of the lovers are connected by the rivet 10 carried by one of the levers, which is adapted to engage a suitable slot, as 11, in the other. By thisconnection the plate is guided so that it is impossible for it to wedge or bind in its movement in opening or closing.

The weather strip or plate is preferably provided with a facing 12 of felt, rubber or other suitable material, for its lower edge.

The inner ends of the levers S are held normally upward by means of the spring 13, the free end of which is connected thereto by suitable link as 14, the other end of the spring being mounted upon the plate by means of a suitable stud 15.

It is obvious that through the connection of the lovers to the door, when their inner ends are held upward, the weather strip or plate is thrown down to the position indicated by full lines in the drawing.

When the door is open, the plate is ele vated by means of the lever 16 which is actuated by a spring 17. The spring 17 is connected to the lower end of the lever and to the stud or post 18 projecting through a slot 19 provided therefor in the plate, the stud being carried by the door. The lever 16 is provided with a curved arm 20 which is adapted to engage the pin 21 on the plate, so that the spring serves to hold the plate normally upward. This spring is of sufiicient durable.

. inner ends of said levers to lift the same,

other at their inner ends, and to said plate strength or tension to overcome the tension 1 of the spring 13, so that, unless the lever 16 is held out of its engaging position, the plate is held normally upward.

The lever 16 is arranged vertically and is mounted on a suitable pivot as 22, arranged through a vertical slot 23 in the plate, as clearly appears in Fig. 4. WVhen the door is closed, the lever is engaged by the trip pin 24 which forces its upper end inwardly, thereby releasing the plate 5, allowing the spring 13 to close the same. As soon, however, as the door is open, the lever is released, so that the spring 17, acting therein, lifts the plate against the tension of the lever 13, holding it open. By this simple means, I secure a weather strip for doors, which, while it is very tight when closed, is automatically opened upon the opening of the door so that the wear on the weather strip and upon the door sill or floor is minimized, it being in fact practically nothing. The structure is very simple and at the same time strong and I have illustrated my improved weather strip in detail in the form preferred by me on account of its structural simplicity and economy. I am, however, aware; that it is capable of considerable variation in structural details Without departing from my invention.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
