SPECIFICATION forming part of lLetters Patent No. 761,395, dated May 31, 1904.

Application tied Janmyeo, 1904,. serial No. 191,363. (No man.)

T a/ZZ whom it may coni-cern: Be it known thatI, WI LIAM J. PERRY, a

citizen of the United States, residing at Redcloud, in the county'of Webster and State of` Nebraska, have --invented .certain new and usel ful Improvements inWeather-Stripaof which the following is a specification.

. tageous when used upon doors inexposed po The object of this invention is to provide a novel construction of weather-strips particularly adapted for use upon doors, the strip being of the pivoted type which is movably mounted upon the door and which is operable by the opening and closing of the door.y

The weather-strip as embodied in my invention lis of a-construction specially advansitions in that the strip is sufficient to prevent entrance of water or other foreign matter.

For a full description of the invention4 and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to vtional View showing the door in closed position and the-disposal of the 'weather-strip when the door is in such position. Fig. 3 is a perspective view, partially broken away, showing the position of the weather-strip when the door is open. Fig. i is a perspective view showing the lower-portion of the door and the` weather-'strip spaced therefrom.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters. i

The invention is'shown applied to a hinged type of door, though it willbe understood that it is contemplated to' use the weather-strip in connection with either a hinged. or swinging door of any type. The adjacent part of the door and the door-frame are-so constructed as to obviate all vswelling'which might be'ca'used by dampness or exposure which might prevent perfect operation'ofl the invention aftersame i has been in use acertain length of'time'.V A Referring to the drawings, the doorframe 1s of usual form and comprises a sill or threshold l and the sides 2, as shown. 'Thethreshf -old or sill 1 is provided with'acovering-plate 5, which extends entirely over the same and lwhich prevents to a certain extent any injurious swelling of the base orsill l should y the same be constructed of wood,,as is customary. The door 6 in closing engages the jamb L and is provided at the lower end with" a recess 7, which extendsV entirely across the lower portion thereof, which recess 7 is closed in front by means of a transversely-disposed plate 8. The sides of the recess 7 are closed, 5

likewise, by means. of said plate 9, which lplates 8 and 9 are firmly secured to the door by suitable fastening means. vThe side plates 9 are provided with openings which receive journals 10 of the weather-strip 1l, the latter being pivotedmbetween the front plate 8 75 kfront edge thereof than the rear edge, so as to vcause the weather-strip to normally remain in a norm al position by its own weight,this`be ing accomplished, of course, owing to the fact that the weight of the portion of the weatherstrip in rear of the journals l0 is greater than that of the portion in front of the journals.

Tolimit the downward movement of the rear portion of the weather-strip 11, a stop or stops 12 in the form 'of' lugs, projected from the inner portions of the recess 7, may be provided, said stops supporting the weatherstrip in its approximately horizontal position normally. The weather-strip is provided `upon its upper and lower sides and atopposite edges with packing-strips 13, said strips being secured invany suitable manner to the weatherstrip and consisting of rubber or like material adapted to afford an air-tight closure. The jambs 4, which are carried by the sides 2 of the door-frame, are provided adjacent the lower ends thereof with arcuate recesses 14C, which recesses receive the front portion of the weather-strip 11 as the door is being closed. In one of the recesses 14 is disposed a springplate 15 with its upper end curved to form a cam portion 16, adapted to coperate with the weather-strip to cause same to assume a vertical closing position, the cam portion 16 bearing against the strip in the above operation. When the door is open, the weather-strip is in the position shown clearly in Fig. 3 of the drawings. However, on closing of the door the front edge of the weather-strip moves into the recess 14 of the jambs 4 of the door-frame, and, striking the cam-plate 15, the weatherstrip is tilted into avertical position, the packing-strips 13 being thus disposed in contact with the inner side of the door-sill and the inner side of the front plate 9, thus establishing an air-tight closure. When the door is open, the weather-strip assumes its normal horizontal position by its own weight.

Having thus described the invention, what is claimed as new is- 1. In combination, adoor-frame, jambs provided at their lower ends with recesses, a door provided at its lower end with a transverse recess extending across the same, a transverse plate closing the front of said recess, side plates closing the sides of said recess, a weatherstrip pivoted between the side plates of the door aforesaid, and a cam-plate disposed in one of the recesses of the jambs of the doorframe and engaging the weather-strip on closing of the door to effect operation thereof.

2.` In combination, adoor-frame, jambs provided at their lower end portions with recesses, a plate secured to the sill of the frame, a door provided at its lower end portion with atransverse recess extending across the same, a front plate closing the front of said recess,

side plates closing the sides of said recess, a weather-strip pivotall y mounted in the recess of the door and journaled to the side plates aforesaid, packing-strips disposed upon the upper and lower sides of the weather-striliis at opposite edges thereof, and a spring cam-plate disposed in one of the recesses of the jambs of the door-frame and engaging the weatherstrip on closing of the door to effect automatic operation of said strip.

3. In combination, adoor-frame, jambs provided at their end portions with curved recesses, a covering-plate disposed upon the sill of the door-frame, adoor provided at its lower end portions with a transverse recess extending thereacross, a plate closing the front of said recess, side plates closing the sides of said recess and provided with openings, a weatherstrip movable in the recess of the door and journaled in the openings of the side plates, means for normally holding the weather-strip in an approximately horizontal position, stops projected from the recessed portion of the door to support the weather-strip in the horizontal position and to limit the movement of the said strip, packing-strips disposed upon the upper and lower sides of the weather-strips at opposite edges thereof, and spring-plates provided with cam portions disposed in the recesses of the jambs and adapted to engage the weather-strip on closing of the door to tilt the said weather-strip into a vertical position.

In testimony whereof I aiix my signature in presence of two witnesses.
