WEATHER-STRIP.

Specification of Letters Patent.

Patented Feb. 20, 1906.

1 Application filed July 31, 1905. Serial No. 272,056.

To all whom it may concern:

Be it known that I, LEwIs W. WOODBURN, a citizen of the United States, residing at Charleston, in the county of Goles and State of Illinois, have invented certain new and useful Improvements in Weather-Strips and I do hereby declare the following to be a full be adjustably fastened to a door in such a manner that as the knob-shaft carried by the door is rocked the weather-strip may be raised as the door is opened, and means is also provided for holding theweather-strip in a raised position while the door is opened.

The invention consists, further, in the provision of a door weather-strip so arranged that it may be actuated or not as the door is closed, and comprisesvarious details of construction, comblnations, and arrangements of parts which will be hereinafter fully described, and then specifically defined in the appended claims.

My inventionis illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of a door, showing my improved weather-strip as applied thereto, arts of the casing being removed to better i1 ustrate the details of the invention.

Fig. 2 is a plan view of a door, showing my inparts for actuating the same, and said casing is fastened, preferably, to the outer face of the door near the bottom thereof. D designates aweather-strip which may be of any suitabldmaterial that may be found well adapted for the purpose and is substantially of a length equal to the width of the door. Guide-arms D project'from the face of said casing and serve to guide the weatherstrip in its vertical movement.

G and G designate two angled levers, the former of which 1s pivotally mounted upon a pin G and the latter upon a pin G projecting from the wall of said casing.

H designates a bar having a lug H projecting from one end thereof, which engages an a erture in an arm of the lever G, and a simi ar lug H projects from the opposite end of the bar'I-I and engages an aperture in the angled lever G. The bar H is guided in its movements by means of a continuation of one of the guide members which serve to retain the weather-stri in its vertical position.

An arm of the ang ed lever G has a series of apertures e therein for the reception of the lower angled .end of the rod I, which is adapted to engage one or another of said apertures for the purpose of raising the long arm of the lever G and in so doing assist in raising the weather-strip D through the medium of the link E, which is connected at its lower end to the loop F and at its upper end to said lever G. The rod I passes through an aperture in the bottom of the casing'I, which is adapted to be fastened to the face of a door and also passes through an aperture in a boxing J and as a head I at its upper end.

K designates a yoke, the free ends of which are bent toward each other, and the lower contracted end of said yoke is apertured, as at K, for the reception of said rod I. A spring J is interposed between the lower end of the boxing and the contracted bottom of said yoke and serves to normally hold the yoke in its highest position. A knob-shaft M passes through an aperture in said boxing J and also through a rocking member 0, the arms of which are positioned underneath the angled endsofsaid yoke and against which they are adapted to bear as said member is rocked. It will'be noted that the'head I of the rod I engages the portion of the yoke about the aperture K and has a tendency to draw down the yoke against the tension of the spring J, as the weather-strip is lowered.

Mountedin a suitable guide L, projecting from the casing in which the weather-strip is held, is a bolt L, the inner end of which is threaded and is mounted in the threaded end of a yoke N, which latter has a shank portion N with an angled end N Q designates an angled lever pivotally mounted at Q and having an arm Q to which the angled end N of said shank portion N is pivotally connected, and the other arm Q of the lever Q projects underneath a lug g, carried by the angled lever G, which is pivotally connected to the casing at G Said weather-strip D, which is provided with the loops F F, is supported by means of the bars E and E, each of said barsbeing turned into a roll for engagement with its loop and the upper end of the bar E is pivot- .ally mounted upon the lug 6, while the upper end of the bar E is pivotally connected to the pivot-pin e.

The lever G is provided with a lug G projecting from one arm of said lever adjacent to the end thereof which is pivoted to the bar E, and. W designates a longitudinally-movable rod which is mounted at one end in a guide D, and its other end is connected'to the up er end of a lever T, which. latter is pivota 1y mounted upon the pivot Q. A spring T is fastened at one end to the casing in which the weather-strip is housed, and its other end is connected to the lever T. Dependin from the rod W is an angled arm V, the ang ed end of whichis normally positioned to engage underneath the lug Gr for the purpose of holding the weather-strip in an elevated position. Projecting from the face of the lever T is a lug 25, positioned in the path of the arm Q of the lever Q, whereby as the lever Q rocks upon its pivot in one direction said arm Q will contact with the lug t and. cause the lever T to tilt and also cause the rod W to be moved longitudinally in one direction sufficient to throw the angled end of the arm V from under the lug G which will .allow the weather-strip to fall by gravity.

A spring Q is secured at one end to the easing in which the weather-strip is housed, and its other end is fastened to the arm Q of the lever Q, the urpose'of said spring being to normally hoid the lever Q in the position shown in Fig. 3 of the drawings, in which the weather-strip is held above the lower edge of the door.

The frame of the door is recessed away, as at S, and S designates a plate (shown clearly in Fig. 4 of the drawings) which is pivotally mounted upon the door-frame and has a proj ection S forming a handle, whereby the plate may be swung so as to expose the opening into the recess or close the same, accordingly as it maybe desired to allow the weather strip to be held above the lower edge of the door or allowed to fall so as to engage the threshold. l

In operation, when it is desired to hold the weather-strip above the lower edge of the door it will be noted that the spring J will serve to hold the yoke K, so that the upper end thereof will not bear against the member without in any way affecting theweatherstrip; but when it is desired to cause the weather-strip to be actuated as the door is opened and closed the plate S is first closed over the recess S, and when the door is closed the outer end of the bolt L, coming in contact with the plate S, will cause a longitudinal movement to be imparted to the bolt L, which is connected to the lever Q, causing the latter to tilt under the tension of the spring Q, the arm Q of said lever Q will tilt down out of engagement with the lug g, and when the inner edge of the arm Q ofsaid lever Q comes in contact with the lug upon the lever T the latter will be tilted under the action of the spring T, and the rod W will be given a longitudinal movement by reason of its being connected with the lever T, and the depending arm V depending from the rod W will be moved from underneath the lug G, thus allowing the weather-strip to fall by gravity, the falling of the weather-strip will draw down upon the long arm of the lever G and through its connections with the rod I the yoke K will be drawn down slightly, putting the spring J under tension and throwing part of the weight of the weather-strip upon the member 0, thereby adjusting the mechanism, so that whenthe knob-shaft is turned in the act of releasing the latch the-member O rocking with the shaft M will cause the yoke K to be raised, thus assisting-in raising the weather-strip, the spring Q also exerting a force in raising the Weather-strip as the bolt L moves longitudinally, tilting the lever Q under the influen ce of said spring Q. When the bolt L returns to its normal position as the door swings open, the spring T will cause the lever T to tilt upon its pivot, and the rod W being moved longitudinally will cause the angled arm V to be thrown underneath the lug G and hold the weather-strip in its elevated position.

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