WEATHER-STRIP.

SPECIFICATION forming part of Letters Patent No. 578,616, dated March 9, 1897. Application filed November 27, 1896. Serial No. 613,676. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE M. WHITE, a citizen of the United States, residing at J efferson, in the county of Greene and State of Iowa, have invented certain new and useful Improvements inWeather-Strips,of which the following is a specification.

This invention relates to weather-strips, and particularly to a weather-strip for hinged or swinging doors or windows, and pertains especially to the class of weather-strips operated by a projection or roller upon a door or window jamb to close said strip hard against the sill thereof with the closing of the door or window.

The object of the invention is to provide a new and improved means for housing an apron or sleeve at the bottom of a door and to provide a peculiar and novel device to make an adjustable spring-hinge connection between the housing and the said leaf or apron.

A further object of the invention is to provide a spring connection between the weatherstrip leaf or apron and the housing therefor which shall be attached only at one end of the said two specified parts.

A still further object of the invention is to provide an operating means for the said apron consisting of a roller journaled to the doorjamb and adapted to engage the apron and gradually close it down upon the door-sill automatically with the closing of the door.

Other advantages and improved results accruing from the special construction and arrangement of the several parts of my invention will be hereinafter disclosed in the specification to follow.

The invention consists in the novel construction and arrangement of parts and resides, essentially, in a spring-hinged connection between the weather-strip housing and the apron.

In the accompanying drawings, forming part of this application, Figure 1 is a perspect-ive view of a door provided with my weather-strip and the roller journaled in the door-jamb for operating the same. Fig. 2 is a longitudinal sectional, view. Fig. 3 is perspectiveview, partially broken away, showing the-apron thrown down as when engaging a door-sill. Fig. 4 is a perspective view,par-

tially broken away, of the housing. Fig. 5 is an enlarged perspective View of part of the tube or barrel shown in Figs. 2 and 3, except that the slotted end of the apron terminates short of the end of the tube. Fig. 6 is a sectional view showing a modified form of spring adjustment.

The same numeral references denotethe same parts throughout the several figures of the drawings.

The housing 1 is secured to the bottom of a door 2 in the usual manner, and a roller 3 is journaled at 4: to the door-jamb 5 in a horizontal plane with the housing. This housing 1 consists of a strip of metal or other suitable material like unto an ornamental molding, having a central bore 6, with a continuous longitudinal opening or mouth 7 from said bore sm a1 ler than the latter, a vertical straight back 8, an overhanging lip 9, and an upwardprojecting lip 10. p

The curved leaf or apron 11 is formed in the same piece with the barrel 12, both being composed of a single piece of sheet metal. The barrel has a set-screw 14 for securing the keeper 15 therein. A similar keeper 16, having a rim or flange 17 inclosing one end of the barrel, a series of apertures 13, and a cavity or slot 13, is adjustably secured in the outer casing of the housing by an adjusting pin 16. The outer end of the barrel is oscillated upon the keeper 16. The inner surface of the flange or rim 17 forms a bearing for the said barrel end and the outer surface abearing for the outer end of the apron 11, having a slot 18, thus making a perfect and effective bearing between the housing,tube, and apron. Said slotted apron end may terminate short of the end of the tube or barrel 12, as shown in Fig. 5, so that said apron end will not strike the door-jamb in operating the door.

The spring 19 is preferably formed of sheetsteel, although for large doors it may be composed of thicker angular metal. The ends of the spring are formed integral with or secured, respectively, to the

keepers

15 and 16, and the tension of the spring is increased or diminished, as desired, by inserting a suitable tool, such as a screw-driver or similar implement, in the cavity or slot 13*, removing the adj ustable pin 16, and turning the keeper 16 until one of its apertures 13 registers with a like aperture in the housing When the said pin is replaced.

A modified form of spring adjustment is shown in Fig. 6, the tube 24 having a series of apertures 25, engaged by a set-screw 26, Which secures one end of a long spring 27 to the keeper 28 and the latter to the tube. The other end of the spring is secured to an outer keeper 29, permanently fixed to the housing 30. To change the tension of this spring, the keeper 28 has simply to be moved back and forth, which increases or diminishes the length of the spring between the keepers. This change of spring tension is highly essential, because it has been found in this class of spring-hinged Weather-strips that the continuous strain upon the spring Will Weaken and seriously impair its purpose to such an extent that it Will not return the apron into its housing clear of the door-sill, Whereas in accordance With the means here described for changing the tension of the spring such obstacles and objections are Wholly avoided, giving the spring longer life and insuring always the certain return of the apron.

The roller is provided in lieu of any other device for the throw down of the apron, because the latter is not Worn or otherwise disfigured by continuous contact With the roller, and the latter is not liable to the Wear and tear of the apron and cannot be readily broken or disabled.

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

1. I11 a Weather-strip, the combination of the housing, with the barrel inclosed by the housing and having an apron, the keeper secured to one end of the housing and forming a bearing for the barrel, and a spring having one end connected to the barrel and the other end attached to the said keeper, as set forth.

a suitable housing, and a barrel operated in the housing and having an apron, of means for operating the barrel comprising a platespring having a lug or keeper at each end, one of said keepers being secured upon the inside of the barrel and the other keeper adjustabl y attached to the housing and forming a bearing for the barrel, as set forth.

3. The combination With a Weather-strip housing having a central longitudinal bore, and a mouth smaller than the bore, of the tube or barrel operated in the bore and having an apron operating through said mouth, a keeper adjustably secured to one end of said housing and upon which the tube or barrel is oscillated, a keeper secured upon the inside of the barrel, and a spring inclosed by forth.

at. The combination with the housing havin g a longitudinal bore, a mouth opening from said bore smaller than the latter, of the tube or barrel operated in the bore, the apron operated through the mouth, the keeper secured to and closing one end of the said bore and forming a bearing for the said tube or barrel, a similar keeper secured in the barrel, and a spring adj ustably secured in the barrel by said keepers, as set forth.

5. In a Weather-strip, the combination of the housing, With the barrel having an apron provided With a slot, the keeper secured to the housing and having a flange inclosing one end of the barrel and engaging said slot, and a spring having one end attached to the keeper and the other end connected to the barrel, as set forth.

In Witness whereof I hereunto set my hand in the presence of two Witnesses.
