WEATHER-STRIP FOR DOORS.

SPECIFICATION forming part of Letters Patent No. 542,007, dated July 2, 1895. Application filed August 17, 1894. Serial No. 520,568. (No model.)

To all whom t may concern/.-

Be it known that I, HoLcoMBE RUDEBooK, a citizen ofthe United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Weather-Strips for Doors; and I do hereby 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, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part ot' this specification.

'My invention has reference to improvements in devices used to prevent the admission of cold air, wind, dsc., through the crevice beneath the door and above the saddle for the door, and therefore relates to anovel arrangement of devices embodying a weatherstrip for doors.

My improvement is designed to secure an automatically-acting weather-strip arranged along the lower edge and on the outside face of a door and means operating to cause said strip to be automatically held in a raised position when the door is opened, and thereby en able the closing of the door, when desired, and said means, when the door is finally closed, causing the weatherstrip to automatically drop against the saddle for the door, and, rest ing on the edge of the saddle, near the door, to positively shut out the entrance of cold air, wind, rain, or snow beneath the lower edge of the door.

The invention therefore consists in the novel arrangements and combinations of parts hereinafter fully described, and finally embodied' in the clauses of the claim.

The invention is illustrated in the accompanying sheet of drawings, in which-- Figure lis a perspective view of a doorframe and door in its open relation thereto provided with the weather-strip and operating devices embodying the principles of my present invention. Fig. 2 is a vertical section Vof the door and its saddle with a vertical section of a casing mortised in the lower part of the door and a certain mechanism for operating the weather-strip connected with the door, all of said parts being illustrated in their inoperative position when the door is closed 4 of the drawings. Fig. 3 is a similar view of' the parts illustrated vin said Fig. 2, but shown ing them in their operated positions holding the weather-strip in its raised position as soon as the door is being opened. Fig. 4 is a horizontal section taken on line fc in Fig. 3. Fig. 5 is a perspective view of a certain pivoted stop-plate, and Fig. 6 is a similar view of a trip-post used in connection with the weatherstrip-operating device. 4

Similar letters of reference are employed in each of the above-described views to indicate corresponding parts.

In said above-described views, a designates the door-frame, a the door, and a2 the saddle for the door. Pivotally arranged along the lower edge of the door a', by means of suitable hinges b or otherwise, is the weatherstrip b, which is preferably made of heavy sheet metal, but may be made of 'any other suitable material. Said weather-strip, as will be seen from Fig. l, extends entirely across the lower edge of the door, on the outside face thereof, and when the same is open is raised, and thus permits the passage of the weatherstrip over the saddle for the door when the latter is being closed; but when the door is closed the lower edge b2 of the strip b drops down upon the saddle along the edge of the same near the door to exclude the entrance of cold air, wind, thc. Directly above said weather-strip b and secured to the door a in any well-known manner I may arrange a molding d, provided with a piece of soft rubber d or other flexible material, which comes in contact with the weather-strip b and is for the purpose of preventing cold air from getting into the room between the door and that part of the strip b where it is hinged to the door, as will be clearly evident from an inspection of Fig. 2. Of course it will be understood that said supplemental weatherstrip above the strip h is not absolutely necessary to the successful working of my invention, and may therefore be dispensed with, if desired. The mechanism for operating ICO secured together in the u-sual manner-by a rivet c'. Said casing is provided with a faceplate c2, and by means of suitable screws c3 the casing is firmly secured in a mortise in the lower edge of the door, near the corner farthest away from the door-frame when the door is open, as illustrated in Fig. 1.

On a suitable pin f, secured at its free ends in the opposite sides of thecasing c, are loosely arranged an operating arm or lever e and a cam-shaped disk g. Said lever is provided with a stop e', with which a pivoted stop-plate h, acted upon by a spring t', engages at a certain time to hold a finger c2 on that portion of the arm e extending through an opening c4 in the face-plate against the under side of the weather-strip Zi, and thereby retaining said strip Z9 in its raised position.

In a slot a3 in the saddle a2 is an inclined plate Zt, and riding against said plate k while the ldoor is being closed is a trip-post Z. Said post, as will be seen from Fig. 6, is provided with an offset Z', and its lowerand smaller portion Z2 fits in a correspondingly-shaped opening c5. (See Fig. 4.) This retains said post in a vertical position and the offset Z prevents its falling from the casing when the door has been opened. The upper end of the post Z is adapted to engage with a suitable recess g' in the disk g as said lower end Z2 rides on the incline 7c, and thereby causes the frictional sliding contact of the sharp end g2 of the disk g against the pivotally-hung stopplate h and throws it out of its holding engagement with the stop e ofthe arm e, which, owing to its own weight and that of the strip b against the supporting-nger e2, will drop and bring the end c3 of said arm e down into a recess a4 in the saddle d2 and the lower edge of the weather-strip b down against the-'saddle, as illustrated in Fig. 2.

The operation of the device is as follows:

. Suppose the door has been closed and the several parts are in their inoperative positions, (illustrated in Fig. 2.) As soon as the door is being opened the projection e4 on the end c3 of the arm e will be caused to ride against the edge Ze of the inclineZc, as clearly shown in Fig. 4e. At the same time the springactuated stop-plate Zt, bearing against the sharp edge g2 of the disk g, loosely arranged on the pin f, forces the trip-post Z down in sliding contact with the incline Zo and permits the spring to force the holding end of the plate h over the stop c', which has been brought directly below the end of said plate Zt bythe action of the projection c4 of the arm e against the edge Zt', whereby the said weatherstrip b is held in its raised position against the inger e2 on said arm e. These positions of the parts are thus retained while the door is open, and while being closed the weather-strip b is per-mitted to pass over the saddle of the door. In closing the door,when the latter has reached the position illustrated in Fig. 3, then the trip-post Z begins to ride up on the incline 7c, thereby causing the partial rotation of the disk g on its pin f, forcing the holding-plate h from its engagement with the stop c on the arm e, the end c3 of the arm falling into the recess a4 in the saddle and the Weather-strip b assuming its position against the saddle, as has been described in the above. The said disk g is held in its operative position'on the pin f in any'well-'known manner, preferably by collars f', While the slotted opening c4 in the face-plate c3 of the casing c will retain the arm e in its proper position on the pinf. The plate his preferably made as illustrated in Fig. 5, having pins Zz', by means of which the plate can be pivotally hung in perforations in the opposite sides of the casing c, as will be clearly evident.

The features of the above-described invention are of considerable importance, as the device is simplein construction and operative under all conditions. v

Of course it will` be evident that certain changes may be made in the details of construction and the arrangements of parts. Hence I do not wish to be understood as limiting myself to the exact arrangement and combinations of parts herein shown and described, as I am well aware that they may be departed from Without departing from the general scope of my invention.

Having thus described my invention, what I claim is 1. In a weather strip for doors, the combination, of a strip, as ZJ, adapted to he arranged along the loweredge and outside faceof the door, a casing, as c, connected with the door, an arm or lever pivotally arranged in said casing, having a stop thereon, a spring-actuated holding plate adapted to engage with said stop, to bring the free end of said arm in lifting contact with said strip. and to hold the same in its raised position when the door is opened, and mechanism connected With said pivoted arm for causing its disengagement from said spring-actuated holding plate and hence from its lifting contact with said strip, consisting essentially of a cam-shaped disk g, a trip post in said casing adapted to engage with said disk, and an incline on the saddle for the door, on which said post rides, While the door is being closed, substantially as and for the purposes set forth.

2. In a weather strip for doors, in combination, a casing, arranged in the lower portion and outside face of the door, a pinf in said casing, an arm c on said pin, provided with a stop c and a lifting portion c3, a pivotally arranged strip b on the bottom of the door with which said portion c3 is adapted to engage to lift said strip, a spring-actuated stop-plate h adapted to engage with said stop c on the arm e to hold it in its raised position, and mechanism connected with said arm e for causing its disengagement from said springactuated holding plate and hence from its lifting contact with said strip b, substantially as and for the purposes set forth.

8. In a weather strip for doors, in combina- IOO IIO

tion, a casing, arranged in the lower part and outside face of the door, a pin f in said casing, an arm e on said pin, provided with a stop e and a lifting portion e3, a pivotally arranged strip b on the bottom of the door with which said portion e3 is adapted to be engaged to lift said strip, a spring-actuated stop-plate h adapted to engage with said stop e on the arm e to hold it in its raised position, and mechanism connected` with said arm e for causing its disengagement from said springaotuated holding plate and hence from its lifting contact with said strip b, consisting Witnesses:
