WEATHER-STRIP.

SPECIFICATION forming part 0f Letters Patent N0. 659,455, dated. October 9, 1900.

Application filedFehrnary 10, 1900. Serial No. 4,779. (No model.)

:To all whom t may concern/.-

Be it known that I, GEORGE L. SOOvILLE, a vcitizen of the United States, residing at West Superior, in the county of Douglas and State of Wisconsin, have invented a new and useful Weather-Strip, of which the following is a specication.

The invention relates to improvements in weather-strips.

One object of the present invention is to improve the construction of that class of weather-strips wherein a slidable strip is fitted in the recess in the bottom edge of the door to dispense with a threshold-strip on the door-sill, and to simplify the construction and render the device efficient and reliable in operation, so that on closing the door the strip will be positively depressed into firm engagement with the door-sill to exclude the weather.

A further object of the invention is to provide means by which the slidable weatherstrip may be readily adjusted or tilted to iit any slant of the floor that may be caused by the settling of a building or otherwise and to enable such adjustment to be effected without taking the door off the hinges.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a perspective View of a door, partly open, provided with a weather-strip constructed in accordance with this invention. Fig. 2 is a vertical sectional view in the plane of the jamb and the door, the latter being closed. Fig. 3 is a transverse sectional view on line 3 3 of Fig. 2. Fig. 4 is a detail perspective view of the slidable weather-strip. Fig. 5 is a detail sectional View of the bumper. Fig. 6 is a detail perspective view of one of the adjustable bearings.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

10 designates the door-j amb, which is provided with the usual internal bead or shoulder- 11, against which the door 12 may press or Abear when it is closed, the door being hinged at 13 t0 the jamb. All of these parts are ordinary in the art, and no novelty therefor is herein claimed.

To accommodate the slidable weather-strip, a recess or channel 14 is cut in the lower edge of the door, and in said recess is snugly fitted a slidable strip 15, which may be made of any suitable material. 'This strip 15 is suspended or hung within the recess or channel of the door by springs, which serve to actuate the strip, thereby dispensing with means for guid'- ing the strip in its proper play and for connectin g the strip to the door other than by the springs. The strip 15 is capable of a vertical play or movement simultaneously with its endwise movement, and the suspensionsprings are arranged to give the proper travel to the strip when the door is open, so that the edge of the strip will lie practically flush with the corresponding edge of the door when the latter is opened. The suspension and actuating springs 21,which are inclined, consist each of a flat piece of elastic metal which is pro vided at its lower end with a rounded or spirally-bent journal 22 and with a flat head 23. The journal 22 of the spring is made by coiling or twisting thelower end of the metal upon itself, and the at head, which is arranged at the upper. end of the spring, lies at an angle to the inclined spring-shank. The springs are secured within the channel or recess of the door by fitting the fiat head 23 against the lower horizontal face ofthe door-recess and by passing screws 24 through the spring-heads 23, so that the upper ends of the springs are fastened securely to the door. The rou'nded journals 22 of the springs are adjustably connected to the upper edge of the strip 15 by means Of bearings 16, arranged in recesses 17 and secured to the said strip by screws 18 or other suitable fastening devices, which pass through longitudinal slots or bifurcations 19 of the bearings. Each bearing, which may be constructed of any suitable material, is preferably formed of a single piece of sheet metal having a straight lower or base portion and an upwardly-extending curved portion provided with a lip or iange 20. The straight horizontal portion is provided with thesaid slot or bifurcation 19, and the curved portion, which extends upward over the bottom of the IOO recess 17, is adapted to interlock with the journal of the spring, the lip or flange being adapted to guide the bearing into engagement with the journal of the spring and facilitating such engagement. By this construction the bearings are detachably interlocked with the springs, and the strip may be applied to and removed from the door without taking the latter o its hinges.

The longitudinal adjustment of the bearing for the spring is to enable the strip to be tilted or inclined at either end, so that it will conform to the configuration of and tit snugly against the floor or sill at any slant of the same that may be caused by the settling of the building or otherwise. If the bearing be moved toward the spring, the corresponding end of the strip 15 will be thrown downward or lowered, and by moving it in the opposite direction it will be elevated. Either bearing may be adjusted in this manner, and the adjustment is effected Without taking the door oi the hinges and by simply detaching the bearings from the lower ends of the springs and thereby removing the strip. The journals of the springs slip under the bearings which hook over the journals, thereby holding the strip in position so that any jarring of the door will not throw it out of place and yet permitting the strip to be disengaged and removed by a slight pressure on its front end. The adjustment of the weather-strip by means of the bearings obviates the necessity of placing the springs the exact distance apart, for the reason that the strip may be readily adjusted, to bring it into a position parallel with the floor whether the latter be horizontal or slightly inclined. The springs and strip are thus connected for the strip to be carried or sustained wholly by the springs, and the latter serve toraise the strip when the door is open, so that the lower edge of the strip will lie practically Hush with the lower edge of the door. The springs, which have their upper ends xed to the door, are adapted to have their free ends move or travel in an arc of a circle in order to impart an endwise movement to the strip simultaneously with its vertical movement.

The depression of the strip 15 when the door is closed is eected by a bumper 25, which is attached to the door-jamb in a position to lie in the path of the slidable strip. This bumper consists of a strip or length of spring metal having a slot or fork 26 at one end, and said bumper-spring is arranged in a vertical position on the door-jamb to have its upper end fastened securely thereto by a screw 27, which passes through a suitable opening in said bumper-spring and is embedded in the jamb. The lower forked end ofthe bumper-spring receives an antifrictionroller 26, which is journaled loosely, as at 29, in the free end of the spring, and this rolthe slidable strip. To prevent the bumper# spring from yielding unduly under the im-` pact or pressure of the spring-con trolled strip 15, I employ an adjustable stop-screw 30, which is secured in the door-jamb at a point between the fastening-screw 27 and the anti friction-roller 26a. This stop-screw offers resistance to the inward movement of the bumper spring under the pressure of the strip 15 when the door is closed, and said screw 80 maybe adjusted more or less in relation to the bumper-spring to project the latter at variable distances from the face of the door-jamb, whereby the bumper may be adjusted to depress the strip 15 more or less, and thus secure nicety of adjustment of the spring-pressed strip, so as to compensate for shrinkage of the door or sill and effect the tight closing of the space between the door and sill by the weather-strip. The head of the stop-screw 30 is accessible through an opening 3l, which is formed in the bumper-spring to permit the operator to introduce the point of a screw-driver or other implement for engagement with the screwto adj ust the latter; butthe diameter of the opening 3l is less than the width of the screw-head in order that the latter may have proper bearing against the bumper-spring to oier resistance to the inward movement of the bumper when the slid able strip presses against the friction-roller, which is carried by the bumper-spring.

Changes may be made in the form of some of the parts while their essential features are retained and the spirit of the invention einbodied. Hence I do not desire to be limited to the specific form of all the parts, as shown, reserving the right to vary therefrom.

What is claimed isj 1. The combination withadoor, of inclined springs secured to the same, a slidable weather-strip, and means for adj ustably connecting the ends of the springs to the weatherstrip, whereby the latter may be tilted in either direction, substantially as and for the purpose described.

2. The combination with a door, of incline springs secured to the same, a slidable Weather-strip, and adjustable bearings mounted on the weather-strip and receiving the lower ends of the springs and adapted to permit the weather-strip to be tilted in either direction, substantially as described.

3. The combination of a door, provided at nal pressure and without taking the door off of the hinges,substantially as described.

4. The combination with a door, of inclined ,springs mounted thereon, a slidable weather-` strip, and bearings adjustably mounted on the weather-strip and provided with `project- ICO ing portions arranged to hook over the ends of the springs and detachably engaging the saine, substantially as described.

5. The combination with a door, of inclined springs secured to the door and provided at their lower ends With rounded portions or journals, a slidable Weather-strip, and the slotted longitudinally adjustable bearings secured to the Weather strip and having 1o curved portions engaging the adjacent end of the springs and provided with projecting lips, substantially as and for the purpose described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in 15 the presence of two Witnesses.
