WEATHER-STRIP.

SPECIFICATION forming part of Letters Patent No.-'754,819, dated March 15, 1904.

Application filed February 28, 1903. Serial No. 145,558. .(No model.) v v To 1l/ZZ whom t may concern:

, Be it known that I, JOSEPH S. SENGLAR, a citizen of the United States, residing at St. Louis, in the State of Missouri,` have invented a new and useful Teather-Strip, of which the following' is a specification.

My invention is an improvement in weatherstrips; and the object of my invention is the construction of a strip of this character adapted to be permanently secured to the lower edge of a door and to fit closely against the sill, thus preventing' a draft under the door.

A further object of my invention is to provide means for raising the strip when the door is opened, thereby preventing the lower surface of the strip dragging across the Hoor as the door swings back. l

Briefly stated, my invention consists of a downw ardly-open casing attached to the lower end of a door, a weather-strip adapted to have vertical movement within and projecting below said casing, and means within the casing for forcing it downward when the door is closed and lifting it when the door is opened, which means are fully shownin the drawings, and particularly pointed out in the specification and claims.

In the accompanying drawings, Figure lis a perspective view showing my weather-strip attached to a door. 'Fig 2 is a longitudinal section through the casing and strip, the operating-rod being in elevation. Fig. 3 is a transverse section showing the position of the parts when the door is closed. Fig. lis a similar sectional view showing the position assumed by the parts when the door is opened. Fig. 5 is a detail perspective view of one of the lifting-brackets. Fig. 6 is a detail view of one of the slotted angle-plates- Fig. 7 is a detail perspective view of the operating-rod. Fig. 8 is a detail perspective view of the weather-strip detached from the remaining parts. Fig. 9 is adetail view showing the retaining-spring in elevation and also in plan. Fig. 10 isa detail elevation showing the rear edge of a door and the end of the casing set therein. Fig. 11 is a similar View showing a slight modication, the weather-strip being positioned in a grooveformed along the lower edge of the door. Fig. 12 is a perspective view of the device, showing the construction of these brackets, and in addition to acting as trally and transversely in the casing is an anstrip E2, which may be of rubber, leather, or

and arrangement of the parts when set in the groove. Fig. 13 is a detail perspective view showing one of the end plates of Fig. 12 detached. Fig. 14 isa perspective view/showing the means for actuating the operating-rod.

. In the practical construction of my device I employ a casing A equal in length to the width of the door and downwardly open. As shown in Fig. 2, this casing is secured to the door B in any suitable manner, the door forming the rear wall of the casing.

Vertically arranged within the casing and adjacent each end thereof are a plurality of angle-brackets C, the narrower faces being perfoi-ated and fastened by suitable bolts or screws to the case, their wider faces extending transversely and vertically across the casing and having rearwardly and downwardly inclined slots C extending from their forward edges to a point adjacent their lower edges. The top of the casing A rests on the upper edge a support for the casing they have other uses, which will appear hereinafter. Arranged cengled bracket D, secured to both the door and thefront wall of the, casing, having anarrow straight-edged slot extending to the lower edge of the bracket.

A metallic flanged vstrip E,-adapted to slide vertically within thecasing, holds between its. downwardly-extending flanges E a weatherother suitable material. 8 5

On the upper surface of the strip E are secured two stirrups F, having laterally-projecting flanges F', by whichthey are secured to the strip, and a cross-pieceF2 connects the two side members of the stirrup adjacent their upper ends. On the outer faces of these side members are eyes F3, through which pass the central bow portions of the loop-springs F4. The construction ofv these springs will be readily understood, the ends o f the loops being bent upward and their side members being secured in the eyes F3.

The stirrups F are so, arranged on the strip E that when the strip is placed in position within the casing they will come one on each side of the bracket D.

The ends A of the casing A are perforated,

and running lengthwise of the casing is an Adjacent each end of the rod is secured a collar G', and in its central portion the cylindrical rod is reduced, being flattened on one side, as at G2, and on each side of the reduced portion is bent upward and then back again into the plane of the reduced central portion. These shoulder portions G3 toward the rear end of the rod are bent at a right angle to the straight portion and then gradually inclined downwardly and forwardly. When placed in position, the rod lies above and out of contact with the strip E, its reduced portion being held in the slot of the bracket D, by which it is held against rotation, though free to move horizontally or vertically. Its end portions rest loosely in the slots C', the collars G lying between the brackets C, which are' arranged in pairs at each end of the casing. The rod passes through the stirrups and beneath the upturned ends of the loop-springs F4, the inclined members of the bent portions being adapted to engage the cross-pieces F2. When the parts are all arranged inthe position described, the ends of the springs F4 would bear against the upper wall of the casing and their bow portions would bear downwardly on the stirrups F, thus forcing the weather-strip downward against the threshold.4 To lift this strip against the tension of these retainingsprings, there are arranged adjacent each end of and around the rod coiled springs H, each bearing at one end against one of the collars G and at its opposite end against one of the brackets C. These springs project the rod forward through the perforated end, the portions G3 engaging the cross-pieces F2, and thereby lifting the stirrup and weather-strip. By perforating the casing at each end it can be used on either a right or left door and on either side, it being only necessary to reverse the rod G. A wear-plate I is placed adjacent the hinged edge of the door in a position to engage the forward projected end of the rod G when the door is closed, thus forcing the rod inward and permitting the springs F4 to force the weather strip downward on the threshold J. As soon as the door is opened the springs H will project the rod G outward and lift the strip, as heretofore described.

In the description above given the device has been considered as secured to the side of the door adjacent the lower edge. It is not essential, however, that the device should be secured in this position. The lower edge of the door on one side may be broken away and the casing set in, as diagrammatically indicated in Fig. 10.

In Fig. l1 the dotted lines indicate the outline of a groove formed along the lower edge of the door, the strip E2 projecting below the door. When positioned in a groove, it is obvious that the casing A, which forms the top and sides, would be unnecessary, as the walls of the groove would be equivalent to said casing, it being only necessary to close the ends of the groove.

In Fig. 12 I have shown the device in perspective ready to be placed" in the groove.

In Fig. 13 is shown detached a view of one of the end plates. The plates A2 are equal in width to the thickness of the door and are set in so that their outer faceswill be flush with the side edges of the door, to which they may be secured by suitable countersunk screws. Integral with and projecting inward from each plate are the rectangular brackets C2, the ends of the brackets being slotted at (J3, these frames being equivalent to the brackets C. The end plates'are perforated at A3, the rod G working through the slots C3 and through the forward plate. The springs H bear against the collars and slotted ends of the brackets, the forward collar working within the bracket at the forward end and the rear collar being without the rear bracket, it being understood that the forward end of the rod is the end that engages the wear-plate I adjacent the hinged edge of the door.

The above description will shoT that a nurnber of minor changes can be made in my invention without in any way departing from the spirit of same or changing its main parts, mode of operation, or results obtained.

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

l. A device of the kind described comprising a horizontal strip, adapted to move vertically, brackets carried by a door adjacent its lower edge and having diagonal slots formed in them transverse to the said strip, stirrups secured to said strip, a rod having shoulders thereon, said rod passing through the slots of the brackets and the stirrups and adapted to engage the stirrups and lift the said strip when actuated in aforward direction, and means for actuating said rod.

2. A device of the kind described comprising a weather-strip, stirrups having eyes on their sides secured to said strip, spring-wire loops having their ends bent upward and their side members engaging said eyes, the said spring-loops being adapted to bear downward on the stirrups, slotted brackets carried by a door adjacent its lower edge, a rod having shoulders and collars formed thereon, said rod passing through the slots of the brackets and the stirrups, coiled springs around said rod, said springs bearing at one end against a collar and at the opposite end against a bracket, respectively, and adapted to force said rod forward and bring the shoulders into engagement with the sth-rups, and means for returning the rod to its normal position.
