WEATHER STRIP.

SPECIFICATION forming part of Letters Patent No. 446,520, dated February 17, 1891.

Application filed June 10,1889. Serial No. 313,670. (No model.)

To all whom it may concern.-

Be it known that I, JAMES H. IIUMMEL, of Mount Vernomin the county of IVestchester and State of New York, have invented certain new and useful Improvements in -\VeathenStrips, of which the following; is a specification, reference being had to the ac companying drawings, and to the letters of reference marked theron.

My invention relates to thatclass of weatherstrips in which a loop of rubber or other flexible material is attached to a metallic base.

In the accompanying drawings, Figure 1 is an end view of my improved Weather-strip. Fig. 2 is a side view of Fig. 1. Fig. 3 is an end view of a modification. Fig. 4c is a side view of Fig. 3. Figs. 5, G, and 7 are face views of my weather-strip applied in different ways. Figs. 8 and 9 are sectional views. Fig. 10 is a cross-section of Fig. 6 at 00 ac.

Similar letters of reference indicate similar parts in the respective figures.

A is a metallic base, which, as shown in Fig. 1, is formed with a central arch at a, and bent around and under at its sides, as seen at Z).

B is a rubber or flexible body formed into a loop, as shown, its outer edges being bent outward and into the side ends of the metallic base A, which are closely pressed upon the flexible body. Thus formed, the metallic base A and flexible loop B are firmly clamped together; and it is seen that the construction is such that in handling the device there is no danger of the detachment of the metallic and flexible parts of the strip, which would not be the case were the edges of the metallic base bent and simply flattened over the edges of the flexible body. In practice I have found that the special conformation given to the edges of the metallic base is necessary to secure a perfect attachment between the base and flexible body.

Another important advantage pertaining to my Weatherstrip is that its construction admits of its reversibility. Thus in Figs. 5 and 8 the strip is shown arranged as a righthanded strip, whereas in Fig. 9 it is shown as left-handed.

The attachment of the strip to the door, window, or other point is made by driving tacks through the central portion of the metallic base, as shown in Figs. 5, 6, 7, 8, 9, and 10.

I11 Fig. 6 the strip is shown arranged to ex elude dust or air from the door or windowin which the crevice is wider above than below. This is done, as will be seen, by gatheringin a greater portion of the rubber or flexible material below than above.

In Fig. 5 the outer flexible body stands parallel to the metallic base, and in Fig. 7 an equal portion of the flexible body is on each side of the base. The metallic base A is formed by suitable rollers or tools into the concavo-convex form shown, by which form the said base is given greater rigidity than if it were fiat or of other form. It is seen that by giving the base the form shown the tacking of it to the object to which it is to be secured has a tendency to draw its edges to said object, whereas if the base were flat the tendency would be to raise said edges, which would be highly objectionable. Further than this, the bending over and under of the edges of the base upon the flexible body has the effect of forcing said edges into the flexible body, thus securing a perfect hold of said edges upon the body, whereas if the edges of the base were simply bent in a flat manner upon the body the edges of the base would perform no function in grasping the material.

In Figs. 3 and 4 a modification of the shape of the metallic base is shown. Here the same formation is given to the base so far as relates to the edges thereof; but the central portion of the base at the arch a of Fig. 1 is indented or depressed, as shown at a, Thus instead of having but one arch, as seen in Fig. 1, for imparting rigidity to the strip, there are in Figs. 3 and Al two smaller arches c c, by the use of which it is found that the strength of the base is even more increased.

From the foregoing it will be seen that my invention supplies a weather-strip which combines in itself great rigidity, and is adapted to be handled without danger of detachment of the flexible body from its base. Further, it will be seen that this strip is adapted to be reversed and used in a variety of other ways hereinbefore pointed out.

Having described my present invention, I claim- As a weather-strip, an arched metallic base having its edges turned or bent inward, com bined with an elastic body having the form of a loop with its edges turned or bent outward in opposite directions, the respective outwa-rdly-tnrne :l edges of the elastic body extending and beingclmnped between the main body of the arched metallic base and its respective inwardly-t nrned ed ges, the construction being such that only onethickness of elastic body is clamped between the main body of the metallic base and each of its inwm-dly-turnededges, substantially as spooi- 1o lied.

In testimony whereof I have hereunto set my hand and seal.
