WEATHER-STRIP.

SPECIFICATION forming part of Letters Patent N o. 639,831, dated December 26, 1899.

Application filed December 1,1898. Serial No. 698,035. (No model.)

To all w7't'07'7t t may 0071.007472:

Be it known that I, GEORGE L. SOovILLE, a citizen of the United States, residingat West Superior, in the county of Douglas and State of Wisconsin, have invented a new and usef u1 Weather-Strip, of which the following isa specification.

My invention relates to improvements in weather-strips of that class wherein a slidable Io strip is Iitted in the recess in the bottom edge of the door to dispense with a threshold-strip on the door-sill; and the purpose of the present improvement is to simplify the construction and render the device efficient and relia- [5 ble in operation, so that on the closing ofthe door the stri p is positively depressed into firm engagement with the door-sill to exclude the weather. A

Afurtherpurpose of the invention is to prozo vide means by which the slidable strip is de'- pressed positively on closing the door, and such depressing Ineans may be adjusted to regulate the extent of adjustment of the weather-strip to compensate for shrinking of the door and of the sill, and thereby eifect nicety in the adjustment of the strip, so as to secure proper closure of the space between the door and the sill.

Vith these ends in View the invention consists in the novel combination of elements and in the construction and arrangement of parts, which will be hereinafter fully described and claimed.

To enable others to understand the invention, I have illustrated the preferred embodiment thereof in the accompanying drawings, forming a part of this specification, and in which- Figure 1A is a perspective view with the door partly open and showing my improved weather-strip applied thereto. Fig. 2 is a vertical sectional viewin the plane of the jamb and the door, showing the latter closed. Fig. 3 is a vertical transverse section on the plane indicated by the dotted line 3 3 of Fig. 2. Fig. 4 is a detail perspective view of the slidable strip with the springs attached thereto. Fig. 5 is a detail sectional elevation of the bumper.

Like numerals of reference denote like and corresponding parts in each of the several figures of the drawings.

10 designates the door-jamb, which is provided with the usual internal bead or shoulder 11, against which the door 12 may press or bear when it is closed, the door being hinged at 13 to 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 cutin the lower edge of the door 12,-and in said recess is snugly fitted a slidable strip 15, which may be made of any suitable material. vThis strip 15 is suspended lor hung within the recessed lower edge of the door by springs, which serve to actuate the strip, thereby dispensing with means for guiding the strip in its proper play or for connecting the strip to the door other than by the springs. The strip 15 is capable of a vertical play or movement simultaneous with its endwise movement, and the suspension-springs are arranged to give the proper travel to the strip when the door is opened, so that the lower edge of the strip will lie practically flush with the corresponding edge of the door when the latter is opened. The strip is provided with a series of inclined ,slots in its upper edge, and in the drawings I have represented the slidable strip as provided with two slots 16 17, which are arranged near the respective ends of the strip and are inclined in the same or corresponding directions. Each inclined slot is provided with a long face 18 and a short side 19, and each slot terminates at its lower end in a rounded enlargement or eye 20.

The suspension and actuating springs for the slidable strip are indicated by the numerals 2l 21, and these springs are inclined to properly fit the slots 16 17. Each spring 21 consists of a fiat piece of elastic metal, which is provided at its lower end with a rounded or spil'ally-bent journal 22 and with a at head 23. The journal 22 of the spring is made by coiling or twisting the lower end of said spring upon itself, and the fiat head 23 of the spring lies at an angle to the inclined spring-shank. The springs are secured within the recess of the door by fitting the fiat heads 23 thereof against the lower horizontal face of the door-recess and by passing the screws 24. through the spring-heads 23, so

IOC

that the upper ends of the springs are fastened securely to the door. The inclined shanks of the springs pass through the inclined slots of the strip, and the round journals 22 are fitted snugly in the rounded eyes 2O of said strip. The diameters of the eyes 2O in the strip and the journals 22 of the springs exceed the width ot the slots at the lower ends thereof contiguous to the enlargements or eyes 20, and this construction prevents the journals 22 of the springs from pulling out of the slots in the strip. The springs and strip are thus connected for the strip to be carried or sustained wholly by the springs, and the latter serve to raise the strip when the door is opened for the lower edge of the strip to lie practically flush to the corresponding edge of the door. The springs, with their upper ends fastened firmly within the recess of the door, are adapted to have their free ends move or travel in an are of a circle in order to impart an endwise movement to the strip simultaneously with its vertical movement, and as the springs are fixed at one end their twisted journals 22 are adapted to turn slightly in the enlargements or eyes of the strip-slots without, however, exposing the parts to disconnection one from the other.

In my improved weather-strip the construction is such that it is necessary to make a single recess in the lower edge of the door,

such recess extending practically the full width of the door and being of uniform size in cross-section, the lower edge of the door within the recess lying in aplane parallel with the exposed edge of said door. This construction simplifies the formation of the door for the reception of the strip and facilitates the attachment of the springs, because it is only necessary to fasten one end of each spring directly to a straight top wall of the recess in the door. Each spring is made from a single piece of resilient sheet metal and is bent to forni a rounded journal at one end and the shank at the other end, that portion of the spring between the shank and the journal being inclined'in order to suspend the weather-strip below the door and to permit said strip to have the necessary vertical play.

From the foregoing description it will be understood that the springs on opening the door move the slidable strip endwise, so as to project its inner end beyond the hinged edge of the door, and to effect the depression of the strip 15 when the door is closed I employ a buinpei25, which is attached to the door-jamb ina 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 bumperspring 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 suit-able opening in said bumperspring and is embedded in the jamb. The lower forked end of the bumper-spring receives an antifriction-roller 28, which is journaled loosely, as at 29, in the free end of said spring, and this roller is adapted to ride against the end of the slidable strip 15, thus reducing the friction between the bumperspring and the end of the slidable strip. To prevent the bumper-spring from yielding unduly under the impact or pressure of the spring-controlled strip 15, I employ an adjust-able stop-screw 30, which is secured in the door-jamb at a point between the fastening-screw 27 and the friction-roller 28. 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 30 may be 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 nicetyof adjustment of the spring-pressed strip, so as to compensate for shrinkage of the door or sill and effeet the tight closing of the space between the door and sill by the weather-strip. The head ot' the stop-screw 30 is accessible through an opening 31, which is formed in the bumperspring to permit the operator to introduce the point of a screw-driver or other implement for engagement with the screw to adjust the latter; but the diameter of this opening 31 is less than the width of the screw-head in order that the latter may have proper bearing against the bumper-spring to offer resistance tothe inward movement of the bumper when the slidable strip presses against the frictionroller, which is carried by the bumper-spring. Changes may be made in the form ot' some of the parts while their essential features are retained and the spirit of the invention enibodied. Hence I do not desire to be limited to the precise form of all the parts as shown, reserving the right to vary therefrom.

Having thus described the invention, what I claim is The combination with a door, a rec'essed jamb, an endwise-movable strip confined slidably on said door and springs connecting the strip to the door, of a slotted bumper-spring attached t-o said jamb and having its free end extended into the recess thereof, a roller mounted in said free end of the bumperspring and arranged in position to ride against the end of said movable strip on closure of the door, and an adj Listing-screw iixed to the jamb and bearing against the bumper-spring to adjust the friction-roller relative to the path of the movable strip, said screw being accessible, for adjustment thereof, through the slot in the bumper-spring, as set forth.

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

GEORGE L. SCOVILLE.
