IMPROVEMENT IN WEATHER-STRIPS;

Specification forming part of Letters Patent No. 18h/1,691, dated November 28., 1876; application filed 4 August 30, 1876. Y

To all whom it may concern.:

Be it known that I, JOSEPH BALDWIN, of Hopedalc, in the county of Harrison and' State of Ohio, have invented certain new and useful Improvements in Weather-Strips; and l do hereby declare that the followin gis a full, clear, and exact description thereof, which will ,enable others skilled in the'art to which it pertains to make and use the same, reference being had to the accompanying drawing, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to improvements in weather-strips, and has for its object to furnish a cheap and simple device capable of being attached to any door without cutting or mortising the latter, and that will be automatic in its operation.

, It consists in a notched r=recessed Weatherstrip, provided with a rear-side projection, and journaled in with capability of a horizontal toand-l'ro movement between a pair of lugs or brackets, one of which is recessed to receive the rear side projection or stop and it c'onsists, further, in other improvements, all of which will be hereinafter more fully explained.

In the drawings, Figure l is a vertical section, and Fig. 2 is a perspective, of a door having my improved strip applied thereto; and Figs. 3, 4, 5, 6, and 7 are detail views of parts.

a is the door, hinged to the frame al. a? is the threshold-strip, and a3 is a portion of the lower end of the jamb, or part of the doorframe against which-the door shuts, with a portion ofthe threshold-strip attached thereto. b b1 are the brackets or lugs in which the weather-stripisjournaled. Theyare provided with suitable flanges b2, which give the necessary facilities for fastening to the door. They may be made of any desired ornamental form,-

with their upper edges made sloping to give pitch or slant to the hood or cover b3, placedthereon for the protection of the strip against rain or other injuring cause. are connected by, or support in suitable bearings, a rod, b4, to which the lower edge of the hood b3 is secured. They are provided with the bearings b5, in which the axes of the Weatherstrip turn. The bracketvb is provided on its inner face with the recess c, in which aV side projection, hereinafter described, on the,

Their outer ends weather-strip, engages, for the purpose of holding the strip elevated when the door is'open.

The bearings bi and the -recess c may be ar-' ranged'in relation to eachI other, so that a straight convex or concave strip may begemployed, instead of the form shown in Fig. l, d is the weather-strip, which lits neatly between the door-posts, aud, when thedoor is closed, vcovers the opening above the thresh old strip. Its end is rounded or slightly curved, as shown at d1, so as not to interfere with the jamb in the openig or closing of the door. Its rear side is shortened by having the portions dzd3 cut from the ends, which permits the setting of the brackets b bl far enough in on the door so as not to strike the door-frame, and so that it Will have a horizontal to-andfro movement on its axes d4 d4, sliding in the bearings b5, whereby it is automatically adjusted to the-curvilinear movements of the door in opening and closing the latter. In cutting away the portion d2, a projection, d5, is left on the weathecstrip, which. projection engages in the notch c, and, when the door is open, holds the strip'in the horizontal or elevated position shown in Fig. 2. Instead of having the projection d54 a part of the strip, as above set forth, I prefer t'o attach to the under side of the strip, by suitable rivets, a long spring, d5, secured near the center of the strip, its end projecting, as shown in Fig. 6.

-When the door is open, the spring will yield to any pressure on the outer Wing of the strip, and will prevent injury thereto. The .sheet metal hood or cover' b3 is secured to the cross rod b4, as hereinbefore stated, and to the door a. It rests on and takes the form of the top of the brackets b b1.

long enough so that when secured to the door Its upper end 116 is made by nails or screws it may be turned down over and protect the latter from the Weather, as shown. The extended end may be so formed that when turned down it will present a neat, ornamental appearance. y c is an angular block, made of metal or other suitable material, and secured to the threshold-strip, for the purpose .of elevating the weather-strip as' the door is opened. It is arranged so that it will be immediately behind the Weather-strip when the door is closed, and so that the slightest movement of the door outward from the jamb will conse the elevationuof the weather-.ship into aliorizontal` position. .By preference Ilform it with the lngY which islet into the jamb,`

and provides facilities for fastenin gs, and also makes a bearing-surface, against which-"thrrounded end d1 moves, and thus protects the jamb from being wonn away.f fmanietallic bearing placed in the post al to protect the latterfrom being worn by the frequent striking'of the weather-stripthereagninst." y r The operation of the device is as follows: The weather-strip being elevated, as shownin Fig. 2, by closing the door the end d5 comesin contact with the post a), and pushes the strip toward the jamb, and just as the door is closed the projection d5 becomes disengaged, and the strip drops into the position shown in Fig. `1. i the block aelevates i When the door` is opened,

the strip toa horizontal position, and as the doox` swings back, the end d1, bearing against the jamb a3, moves the strip towaizdv the lng b, i

cess aand hold theisttip elevated;
