WEATHER-STRIP.

SPECIFICATION forming part of Letters Patent No. 313,921, dated March 17, 1885.

Application filed April 29, 1884. (X0 model.)

in the county of Vernon and State of Missouri,

have invented certain new and useful Improvements in WVeather-Strips; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a perspective view of my invention, showing it applied to a door and door-sill. Fig. 2 is a vertical section showing the door closed; Fig. 3, ahorizontal section showing the door partly open; Fig. 4, a detail View in perspective of the spring-plate. Fig. 5 is a detail view in perspective of the L-shaped plate which is hinged to the door.

The present invention has relation to that class of weather-strips for doors in which is employed a rectangular metal plate hinged to the sill of the door-frame, acting in connection with a grooved wooden strip nailed to the door, so that when the door is closed the edge of the metal plate will enter the groove in the strip and form a tight joint, to keep out the wind, rain, or snow.

It is the object of the invention to dispense with this grooved strip of wood, and substitute therefor a second hinged metal plate, and instead of making them perfectly flat, as heretofore, they are made L shape, to increase their efficiency and render their operation more certain. These objects I attain by the construction and arrangement of the several parts, substantially as shown in the drawings, and hereinafter described and claimed.

In the accompanying drawings, A represents the door, and B the usual sill of the doorframe 0, which parts are all of the usual construction.

To the sill B is hinged a metal plate,D, bent, as shown in Fig. 2, so that a space will be left between it and the door-sill, said plate being slightly narrower than the sill, and extending the entire length thereof. This plate heretofore has usually been made flat, and consequently when hinged to the sill and the door closed it could not be brought to a horizontal plane immediately under the door, so that it would be between the sill and door, but, on the contrary,would remain in the rear of the sill, and therefore in order toi form a tight joint a grooved strip had to be employed for the metal plate to enter when the door was closed. The employment of this grooved strip had its objections, for the reason that the joining together of the plate and strip when closing the door was not always effected, and es pecially would this be the result did the plate become bent. To dispense withthis grooved strip is one of the essential features of my in-' vention, and therefore in place of using a flat plate it is L shape, as shown, allowingit tobe so connected to the sill that when the door is closed instead of remaining in the rear thereof it will come directly under it, as clearly shown in Fig. 2. An L -shaped plate, E, is employed, which is hinged to the side of the door A, and extends around the under edge thereof, and when the door is closed the plate I) will pass between the plate E and the under edge of the door, forminga complete and perfectly tight joint against wind, snow, or rain, the vertical or upright portion of the plate E coming against the edge and corner of the door.

As will be seen, the two L -shaped plates D E operate perfectly in connection with each other, and the strip usually employed, which is nailed to the side of the door, is entirely dispensed with, and should the plate D become slightly bent out of a true line the operation of it with the plate E would not be affected. A semicircular groove, a, is formed in the lower edge of the door A, to increase the efficiency of the device or weather-strip. A spring-plate, F, of peculiar construction, is connected to the door-frame, and consists of an upwardly-bent or convex arm, I), an elbow, 0, and the upright Wing at by which it is secured to the door-frame. As the door is being closed the spring-arm b is flattened out by pressure upon it of the plate E, and by its natural tendency to resume its normal shape it keeps pressed upward the plate E against the plate D, andthus insures a perfect and effective joint between the two plates. It will be noticed that the elbow c is bent upward at an angle, so that as the door is being opened the elbow will press the plate E up against the 1 plates hinged, respectively, to the side of the edge of the door and hold it there until the door and to the door-sill, so that when the door door is again closed. As the door is being is closed both plates will lap each other diclosed, when the plate E passes the highest rectly under the edge of the door, in com- 5 point of the elbow c it will drop sufficiently bination with a plate having a convex spring- 20 to enable it to pass between the plate D and arm and'upwardly-bent elbow, and connected door-sill, after which,or at the time the plate to the frame of the door, substantially as and E is commencing to pass under the plate D, for the purpose set forth. the spring-arm b will be flattened out against In testimony that I claim the above I have 10 the sill and act by its upward pressure to re hereunto subscribed my name in the presence tain the plates in close contact with each other. of two witnesses.

Having now fully described my invention, what I claim as new, and desire to secure by Witnesses: Letters Patent, is J. H. MAUS, I 5 In a weather-strip, two L shaped metal W. F. MARING.
