DOUBLE-ACTING OUTWARD-PULLING WEATHER-STRIP.

SPECIFICATION forming part of Letters Patent No. 277,887, dated May 22, 1883.

Application filed October 2, 1882. (No model.)

To all whom "a? may concern:

Be it known that I, EDWARD GoNKLIN,-oi Ghannahon, in Will county, and State of Illinois, have invented certain new and useful ImprovementsinDouble-ActingOutward-Pulling Weather-Strips for Doors, the construction and operation of which I will proceed to explain,reference being had to the annexed drawings and the letters and figures thereon, in which Figure l is an end view of the strip on the door, Fig. 2, a cross-sectional view of the weather-strip, and Figs. 3, 4, and 5 views of the parts forming the spring-joint.

This invention relates to certain improvements in weather-strips for doors of the class that are provided with a leaf hinged to the outer face of the door near the bottom, and so arranged as to close the aperture between the door and the threshold to prevent dust, rain, or wind from passing under the door when it is closed.

. Referring to the show the door at D. I

B is a cleat attached to the outer side of the door, and provided with an overhanging or projecting hood, (1., to cover the leaf a, which is hinged, as shown in Fig. l, to the lower outer corner ofsaid cleat, so that when the leaf it hangs perpendicularly it willfall outside the threshold K, as shown in said figure.

drawings, Figs. 1. and 2 The leaf a is provided with a spring joint" by. means of which it is held up, as shown in Fig. 2, or down, as shown in Fig. l. The springjoint consists of the stud 0, set in the cleat B, and the plunger 0, set in the leaf a on the coilspring S, so their faces meet, as shown in Figs. 1 and 3. The stud c has its face beveled at an angle of about forty-five degrees, and is provided with the slot 0 across its face, as shown in Fig. 4, to receive the corresponding projection, a, on the beveled face of the plunger 0.

'The resiliency of the spring S holds the plunger c in contact with the stud c with considerable force, so that when the leafa. is raised or started up a little the plunger and springwill carry and hold it up, as shown in Fig. 2. When the door closes, the leafa engages with a stud, 'v, on the jamb A to start it down, and the action of the spring carries the leaf down, so that it hangs perpendicularly outside of and against the outer face of the threshold, as

shown in Fig. 1, so as to cause a constant pressure of the leafa against the thresholdby means of the resiliency of the spring S forcing the face of the plunger 0 against the stud oin the position shown in Fig. 3, thus holding the leaf a in the position shown in Fig. 1, as is obvi ous from the shape of the faces of the stud c and plunger 0. The door is thus held closed by force of the spring, as well as having the opening under the door closed, instead its being forced a little ajar, as is the case in all that class of weather-strips where the leaf is held down by contact against some obstruction. When the parts are in the position shown in Fig. 2 there is a constant effort on the part of the stud c and plunger 0 to come in line with each other on accountot the contact oftheir two faces and the resiliency of the spring S. When theleafa hangs down, asin Fig. 1, the stud cand plunger 0 are in the position shown in Fig. 3, and the resiliency of the spring holds them in such position, as is obvious from the form of their faces. WVhen the door opens, the leaf a drags over the threshold K, and is raised thereby sufficiently to give it a start upward, when the spring-joint described carries it up and holds it there, as shown in Fig. 2, until its return against the stud 1; causes it to return again, as shown in Fig. 1.

The leaf to maybe hinged to the 'cleat or hood above it in any manner so it will be weather-tight, and so itwilloperate in the manner described. I

Any number of such spring-joints may be used along the length of the leaf that may be necessary, or any other form of spring used that will perform the same function. By this means the space under the door is not only closed effectually, but the door is held closed against the stops or jamb by constant pressure of the leaf a against the outside of the threshold in the manner set forth. The leaf a falls down to the floor or sill K against a part of the threshold that is not worn as the top of the threshold generally is, so that a close fit is insured to the floor or sill, as well as against the outer face of the threshold. The great advantage of this weather-strip over others is that the leaf a, when down, as shown in Fig. 1, is constantly pulling the door shut and holding it tightagainst the stops orjamb instead of pushing it backward and a trifle open, as in most other cases, so that there are openings and cracks for the wind and dust to enter, and twisting the door out of shape to spoil it. It is this idea or principle of holding the door closed by constant pulling force of the leaf or that I desire to cover, and I do not confine myself to any particular form of hinge or leaf, only so that the principle is maintained. Any kind of a hood to cover the leaf a may be used so it will permit theleaf to operate as described, and render the attachment to the door weather-tight.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is as follows, to wit: H

1. In a Weatherstrip for doors, the leaf a, hinged at its upper edge to the cleat B, and provided with the spring-joint, consisting of the stud c, plunger 0, and coil-spring S, where- 20 by the resiliency of the spring S holds the leaf a either up or down, as and for the purpose set forth.

2. In a weather-strip for doors, the combination and arrangement of the leaf a, spring 25 S, plunger 0, stud a, hood a, cleat B, and hinge H, with the door D, as and for the purpose set forth.
