JAMES C. BRANN ON, OF INDEPENDENCE, KANSAS, ASSIGNOR OF ONF-I'IALF TO ALBERT H. MOLAUGHLIN, OF SAME PLACE.

WEATHER-STRIP.

SPECIFICATION forming part of Letters Patent No. 582,451, dated May 11, 1897.

Application filed May 25, 1896. Serial No. 593,076. (No model.)

To all whom it may concern' Be it known that I, JAMES C. BRANNON, of the-city of Independence, in the county of Montgomery and State of Kansas, have invented certain new and useful Improvements in feather-Strips; and I do declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it 'appertains to make and use the same, reference being had to the accompanying drawings, (and also to Letters Patent No. 246,656, of date September 6, 1881, granted to myself for the invention of certain new and useful improvements in weather-strips, upon which the present is an improvement,) which form a part of this specification, and in which Figure 1 is a top view of my improved weather-strip with a part of the cap-plates removed. Fig. 2 is a perspective view of a part of the same with two of the sections of the strip drawn apart so as to show the manner of connecting the several sections of same in completed strip when in position. Fig. 3 is a perspective view of one section of the top of cap-plate of said weather-strip. Fig. 4 is a cross-section of the end of the base plate of strip through line a a, Fig. 1. Fig. 5 is a front edge view of the completed strip as it appears in position. Fig. 6 is a crosssection of completed strip through one of the parallel chute-sections c, Fig. 1, showing the form and shape of base-plate A and capplate B at that point. Fig. 7 is a cross-section through transverse ribs 6 and lug ithereto attached.

Similar letters of reference indicate corresponding parts in all the figures.

My invention has relation to weather-strips for door-sills; andit consists in the construction and combination of parts of a cast-iron strip adapted to prevent water from entering the house under the door, substantially as hereinafter more fully described, and particu larly pointed out in the claim.

My weather-strip,which is inserted between the door-sill and lower edge of the door, is composed of six partsviz., base-plates A A A and top plates or cap-pieces B B B, all of which are made (by preference, so as to insure the requisite degree of strength and durability) of cast-iron of the shape and construction shown in the drawings-that is, the base-plates A A A are constructed as shown at A, Fig. 6, the front edges of which rest upon the sill outside of the door and the inner edges upon the floor inside the house. The inner edges have beveled raised edges b,-terminating in a level surface or shoulder 01 at the top, which drops abruptly down, forming 6o abutments or flanges for the inclined planes 0, which are divided by one or more transverse ribs f (each one of which is broken off before it reaches the raised flange (Z) into a series of parallel chute-sections C.

At the right and left end of the end sec tions of the base-plate A the beveled raised edge I) and the shoulder 61 extend beyond the incline c, substantially as shown in Fig. 1. At these ends of these sections named there are shoulders extending transversely across the end of base-plate A, of the same height and level with the shoulder d, to the outside edge of the door, and from thence inclining down to the front edge of the baseplate, substantially as shown in Fig. 2. In these transverse shoulders are rabbets g, of the proper depth to receive the ends of the cap-plate B, as shown in Fig. 1 at g. At the left-hand end of each of the two right-hand sections of base-plate'A are transverse ribs e, of the same height and length of the transverse ribs f, for the purpose of supporting the ends of the cap-plate B. At the top of the incline of said ribs 6 are lugs 2' for the purpose of holding in place the inner ends of cap-plate B, as shown in Figs. 1 and 7. At the right-hand end of each of the two lefthand sections of base-plate A are tenons 70, extending laterally beyond the ends of said sections a distance sufficient to form a firm support for the adjoining section of base-plate B, said tenons being of the form shown at 70, Fig. 6, by which each of the three sections of base-plate A are held firmly in position. The cap-plates B are constructed as shown at Fig.

3, one end of right-hand and left-hand sections thereof being fitted to rest in the rabbets g g. The inside ends of said sections and both ends of the middle section thereof rest IOC upon transverse ribs 6 e, in which ends are notches which fit around the lugs i, which,

with the mitered ends in rabbets g, hold capplates B and prevent any horizontal movement of cap-plates B when placed in position. To hold cap-plates B firmly in place and at the same time attach the completed strip to the door-sill, screws are inserted through capplate 13, the transverse ribs f, and base-plate A into the door-sill, the heads of said screws being countersunk into cap-plate B even with the incline of cap-plate, as shown in Fig. 5.

In the application of the strip the beveled base-plates A face the inside and the beveled cap-plate B the outside of the house, and as the water is dashed by rain or from other sources up against plates B and in under the door it enters the groove between the inner edge of plates B and the parallel shoulder 61 of plates A, from which it escapes to the outside of the door and house through the inclined channels 0 c 0, formed between plates A B. If the groove above described or its outlets c c a should become clogged up from any cause, they can readily be cleared by withdrawing the screw that holds the capplate B over the clogged section or sections and removing the cap-plate, which, with its readjustment, is but the work of a moment.

The strip is made in three sections, so as to be more easily adjusted in position without marring the jambs of the door or its casing. The middle section of strip can be cast of various lengths, so as to fit different widths of door-openings to lessen the danger of warping in casting the sections, they being shorter and less liable to warp, that in case of injury to or the breaking of any part of the strip the broken part may be replaced with a new section at about one-third the cost of an entire new strip, which would have to be used to replace a broken one if strip were cast in one piece.

In placing the strip in position the end sections of base-plate A are adjusted to the framework of the door on each side thereof. Then a middle section of said base-plate A of the requisite length to fill the space loo-- tween the two end sections is selected, and after leading the joints connecting the several sections with some thick lead and oil paint the middle section of the base-plate is placed in position. Then the end sections of cap-plate B are placed and screwed fast in position. A middle section of cap-plate B of the requisite length is placed in position and screwed fast and the adjustment of strip is completed, requiring only a few minutes in its adjustment. The object'in leading the joints of the sections of base-plate A is to prevent water from passing through and under base-plates.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States- In a weather-strip, co nstructed in three sections, the base-plates A, A, A, provided on their upper sides with a raised shoulder (I, dropping abruptly to inclined plane 0, having transverse ribs f, f, e, e, terminating short of vertical wall of shoulder (Z; lugs i, '21, on transverse ribs 6, e; tenons 7t, 7t connecting several sections of base-plates A, A, A; transverse shoulders on end sections of base-plate A; mitered rabbets g, g; in combination with cap-plates B, B, B, the end sections mitered to fit in rabbets g, g; the inner ends notched to fit lugs i, 71, and held in position upon baseplatcs A, A, A, by screws passing through capplates B, transverse ribs f, f, base-plates A, into door-sill, substantially as described.

JAMES C. BRANNON.
