WEATHER-STRIP.

938,107. A It Specification of Letters Patent.

Patented Oct. 26, 1909.

vApplication led .Tuly 20, 1908. Serial No. 444,311.

To all whom 'it 'may concern:

Be it known that I, WILLIAM C. F. BEALE,

citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, Ahave invented a certain new and useful Improvement in Weather-Strips; and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains lto make and use the same, reference being had to the Vaccompanying drawings, which form a part of this specification. v My invention relates to an improvement in weather strips shown inthe accompanying drawings and more particularly pointed out in the claims.'

The object of this invention is to provide means whereby the strip will automatically adapt itself to the varying conditions of a worn sill, eectuallyy closing the opening between the door and sill irrespective of whether the opening between same when the door is closed is great or small, of equal width throughout, or an irregular shaped crack.

' Another feature of the construction is the means provided for raising the strip immediately upon opening the door in order that `the latter may freely swing over rugs or carpets and also to relieve the strip of the constant wear due to the friction caused by dragging it over the floor.

In the drawings accompanying this application: Figure l is a `fragmentary lelevation of a door and its casing, with parts in section, showing the strip in the position it occupies before the door isy fully closed. Fig. 2 is a similar view showing the'door completely `closed and the manner in which the flexible strip adapts itself to the irregularities of a worn sill. Fig. 3 is a horizontal sectional view along the dotted'line of Fig. 2. Fig. 4 is an enlarged cross-sectional view through the door and strip on the dotted line y-y of Fig. l. Fig. 5 is an enlarged cross-sectional view on the dottedl line z-z of Fig. 2. Fig. 6 is a perspective view showing a detail of the outer wall vof the strip and the manner of securing it to the door. Fig. 7 is a perspective view of a detail showing the manner of securing the rubber or felt strip tothe fiexiblerod.

Referring now to the letters of reference displayed upon the drawings: A indicates the door, 'B the casing, and C the sill.

D denotes the side walls of the weather strip provided with outwardly projecting j lugs or ears d, whereby it is secured to the door.

E is a reciprocating bar housed between the side walls D and provided with projecting lugs e, between each pair of which are Y As shown in Fig. 3 the tapped hole in the i' latch-bolt Gr passes completely through it in order that the screw-bolt I-I may be conveniently adjusted by a screw driver from the outside.

Gr is avbeveledstrike plate secured to the N door casing to receive the impact of the latch-bolt whereby the connected reciprocating bar Eis forced to the limit of its movement upon closing the door.

I is a flexible strip of rubber or other suit- A* able material, suspended from the yielding rod'J.

K are hollow sliding members traveling in c y suitable ways ,7c formed in the-side Walls D,

their lower ends vbeing secured. to the yielding rod or bar J. Y

L are springs housed within the hollow member K, against which bear the long arms of the bell-crank levers F.

M are coil-springs secured at one end to the bell-crank levers and at the other to the side walls D. The action of these springs'is to return the bell-cranks and with them the reciprocating bar E back to their initial position immediately upon opening the door.

' Having indicated the several parts by reference letters,` the operation of the device will be readily understood.

To insure a sufficient movement of the rubber or flexible strip I, the screw-threaded bolt H is adjusted by means of a screw driver inserted through the hole in the latchf bolt. Upon closing the door the latch-bolt contacting with its beveled strike plate the yielding rod J to which the rubber strip l I is attached.

It will be seen that the yielding rod J lto which the rubber strip is secured readily adapts itself to the wornn or irregular surface'of the sill, while the action of the reciprocating bar E acting in conjunction with the bell-crank levers F and sliding members K force the rubber strip into close and intimate relation with the surface ofthe vsill upon closing the door. So also it willbe seen that the springs L housed within the sliding members permit of a greater ieXibility of movement, allowing the strip to readily adapt itself to the contour of the sill without danger of straining or breaking the parts. Immediately upon opening the door the reciprocating bar E is released from its forced position while the springs connected with the bell-cranks serve to force it back to its initial position, at the same time liftthe rubber strip from contact with the The device may either be lodged within a channel cut in the edge of the door'as'shown in the drawings or it may be secured to the vside of the door andthe parts boxed inas desired. When lodged in a channel as shown in the drawings, Iprefer to cut the channel deeper than is necessary to receive the device, lling the space at the top withv a wooden strip O. My object in doingfthis is that in case it should be necessaryto trim olf the bottom ofthe door on account of the latter sagging, the strip may also be trimmed down and the device moved up in the channel to adapt itself to the changed conditions.

While I have described this invention as applied to doors it may be employed with equal advantage on windows.

Y Having thus described my invention, what I claim is i Y 1. In a device of the character described, a supporting frame secured to the door, a reciprocating bar housed in the frame and having a socket in one end, a screw bolt projecting from said socket, a door frame engaging member provided with a socket to Y receive the projecting end of said screw bolt, the door frame engaging member being adjustable toward and away from the reciprocating bar by said screw bolt, a weather strip mounted in said supporting frame, a `cony tinuous iiexible element by which the weather strip .is supported, means between the reciprocating bar and the weather strip to force the latter downwardly when the bar is reciprocated in one direction, and means for elevating the weather strip when the bar is moved in the opposite direction.

2. In a device of the character described, a supporting frame secured to the door, a reciprocating bar housed in the frame and i having a socket in one end, a screw bolt projecting from said socket, a door frame en-` gaging member provided with a socket to receive the projecting end of said screw bolt,

the door frame engaging member being adjustable toward and away from the reciprocating bar by means of said bolt, a weather strip mounted in said supporting frame, a

flexible-element by which the weather strip is supported, bellcranks mounted in the sup- 1 porting frame for engagement by the reciprocating bar when the latter is moved in one direction to eect a lowering of the weather strip, and yieldable means having connection with' said bell cranks to move the latter and thereby shift" said bar in the opposite direction when the door is opened tovpermit of a raising ofthe/weather strip; L 3. Inl av device of the class described, a ysupporting frame adapted to be'secured to a door, a reciprocating bar housed in the frame and adapted to be movedpin Vonerdirection by closing the door, a weather strip, a continuous eXible metallic bar to which said weather strip is secured, .connections includingflexible elements between ,theV bar and said strip to force the latter'downl wardly when the bar is movedinwardly on closing thefdoor and means having connection withthe aforesaid connections for elevating the weather strip` when the bar, is reciprocated in the opposite direction Vupon opening the door and consequently eectmg a raising ofthe weather strip. 1 Y
