-WEATHER-STRIP.

SPECIFICATION forming part of Letters Patent No. 396,181, dated January 15, 1889.

Application filed May 26,

To all whom it may concern;

Be itknown that I, JOSEPH W ALKER, a citizen of the United States, residing at Belleville, in the county of Republic and State of Kansas, have invented a new and useful Improvement in eather-Strips, of which the following is a specification.

My invention relates to improvements in weather-strips, having for its object to provide a simple, cheap, and effective device to prevent wind and moisture from penetrating between the door or window) and the casement; and it consistsin a certain novel construction and combination of devices, fully set forth hereinafter in connection with the accompanying drawings, wherein- Figure 1 is a perspective view of a door provided with the improved weather-excluding devices. Fig. 2 is a perspective view of the door, looking at its lower edge. Fig. is a vertical sectional view of the door. Fig. 4 is a horizontal sectional view of the same. Fig. 5 is a detail view of one of the sheetmetal holders which are employed to engage the strips. Fig. (5 is a plan view of the sill. Fig. 7 is a detail view of the hinge.

Referring to the drawings by letter, A designates the easement of the door, the sill B of which is provided with a longitudinal drip-groove, b; and C designates the door, which is hinged to one side of the easement by means of the sliding joint-hinges D D. These hinges consist of the stationary straps E E, which are secured to the casement and are provided with the rigid knuckles e c, and the swinging straps F, which are secured to the door and are provided with the knuckles f, vertically movable on the pivot-pins G. The lower stationary knuckles in the hinges are provided at their upper ends with the semicircular notches e, and the' movable or sliding knuckles f are provided with the depending semicircular projections f to fit in the notches 6 when the door is in its closed position.

It will be evident from the above that as the free edge of the door strikes the easement the door will drop slightly, as the projections engage the notches, and in order to allow the door to swing open freely it will be neces sary to slightly raise it to disengage the said projections from the notches.

1888. Serial No. 275,133. (No model.)

The edges of the door are provided with longitudinal grooves H, 011 both sides of which are arranged the channels I I, the said groove in the hinged edge of the door being, however, inclined slightly, for a purpose to be described.

The holder K is composed of sheet metal, and consists of the flat roll 7;, engaging the edge of the flexible strip L, and the lateral flange 7; which is formed integral with the roll. The rolls of the holders are arranged' in the above mentioned grooves in the edges of the doors, and the flanges are arranged flat against the edges of the door, and may be secured thereto in any suitable or preferred manner. The holder at the hinged edge of the door being arranged in an inclined groove, as described, the flexible strip which is engaged in the holder will alsobe inclined, so that when the door is closed the strip will be bent over against the side of the easement and received in the channel I, and will not be doubled or crushed, as would be the case if the said strip were arranged perpendicularly to the edge of the door.

The hinge is so constructed (as before explained) as to drop the door as the free edge thereof strikes the easement, so that the flexible strip on the lower edge is also bent over and compressed against the sill.

M h[ represent anti-friction rollers, (three or more in number,) which are mounted in castings N N, secured in recesses in the lower edge of the door, and shallow sockets O O are formed in the sill to receive the lower sides of the rollers when the door drops, as described. The inner sides of these sockets are beveled up to the upper surface of the sill, so that when the attempt is made to .open the door the rollers successively travel up the said beveled sides of the sockets and gradually raise the door sufficiently to disengage the projections from the notches of the hinges,

and before the inner roller (or the roller adjacent to the hinged edge of the door) leaves the sill the said projections are out of alignment with the notches, and the door swings freely with its lower edge out of contact with the carpet. Thus there is no difficulty experienced in either opening or closing the door, the weather-strips being brought into the operative position only when the door is entirely closed, and therefore there is no unnecessary wear on the said strips.

The dripgroove before mentioned, which is loeated under the lower edge of the door when the latter is elosei'l, is in a position to reeeive the nniisture which drops from the door and prevent water from being driven under the same, and small el'n'tnnels l are formed in the sill to conduct away the water which aeeumulat es in the groove.

It will be evident that the eompressed strips at the edges of the door form impassable barriers to the entrance of the wind and rain \\'l\l('ll is driven against: the door.

llaving thus deseribed my invention, l. elai1n 1. The (t)illi)lllzti'lOll, with a door mounted on sliding joint-hinges, oi? the flexible strips attzlehed to the edges ol the door and the anti[ri(':tion rollers mounted on the l'tottom oil the door, substantially as speeilied.

2. The eoniltination, with a door having strips on its edges and mounted on sliding joint-hinges, oi the anti-trieth'm rollers mounted on the lower edge of the door and hearing on the sill, and :ulapt'ed to be reeeived in beveled soekets in the sill, snbstz'intially as 3. The combination, with a door frame or easement and sill having a dri 'i-grot'ne, the ehannels leading from the groove, and the 5 beveled sockets of the door, the sliding joint.- E hinges having projections on the lower ends 5 of their movable knuckles to engage corresponding notches in the upper ends of lower stationary knuekles, whereby the door drops as its free edge strikes the easement, and the anti-friction rollers mounted on the lower edge of the door and hearing on the sill, and adapted to he received in the said sockets in the sill, all constructed and arranged to operate substantially as and for the purpose hereinhelore specified.

-l. The combination, with a door provided with grooves in its edges, of the holders K, loeated in the grooves, and comprising the rolls is, formed by doubling the holder twiee upon itself", and the flanges 7r, bearing on, the edge of the door and formed integral with the rolls, and the flexible strips arranged at their inner edges in the rolls and doubled on themselves therein, and, nojeeting at their outer edges beyond the edge of? the door, substantially as specified.

In testimony that l elaiin the foregoing as my own I have hereto al'tixed my signature in presenee of two witnesses.

JOSEPH WALKER.
