No. 614,976, Get. 9, 1956. This application Jan. 11, 1961, Ser. No. 82,127 11 Claims. (til. 20-64) This application is a continuation of application Serial No. 614,976, filed October 9, 1956, which has now become abandoned.

This invention relates generally to building structures and more particularly to a sill assembly, and still more particularly to an assembly wherein the sill per se can be used without the other elements of the assembly, or with one or other of these other elements, which other elements are termed herein the threshold and a pair of wedges.

A primary object of this invention is to provide apparatus for use in the finishing of exterior openings in buildings, with an improvement in the overall efiiciency of the finished product, as well as an accelerated and simplified building procedure being made possible by the use of this invention.

An ancillary object of this invention is to provide apparatus which, when fully used, will considerably decrease the actual labor and skill required in finishing exterior openings.

Another object, equally important, is to provide a threshold which can be employed with a door having an interlocking type of weather stripping on its lower edge, and which will drain any moisture from the interior side of the door to the sill at the exterior side of the same door, without any deleterious effects or the addition of any unsightly structure.

Yet an other object of this invention is to provide a sill and threshold assembly wherein the threshold is reversible for use with finished floors of different thicknesses.

Another object of this invention is to provide a sill and wedge assembly which is extremely simple to install and which provides a perfectly finished appearance, the life of the framework of the exterior opening of the building being considerably lengthened when this assembly is used in the construction thereof.

With these objects definitely in view, along with other objects which will appear hereinafter as this description proceeds, this invention consists in the novel construction, combination and arrangement of elements and portions, as will be hereinafter fully described in the specification, particularly pointed out in the claims, and illustrated in the drawings which form a material part of this disclosure and in which:

FIGURE 1 is a. fragmentary, isometric View of a doorway with this invention incorporated therein, certain portions being shown in vertical section, the figure being proposed as showing how the sill, wedges and threshold are positionally related in use;

FIGURE 2 is a view of the sill and one of the pair of wedges, in properly related position and the fragmentary showing of a wall being included in the figure to indicate how this assembly is used in an exterior opening of window character, this figure also representing the relationship of the sill and wedges when used without a threshold, although the floor would in the latter case extend to the left of the structure shown in the figure;

FIGURE 3 is a side elevational view of the threshold;

FIGURE 4 is a vertical sectional view of the threshold, taken substantially on the line 44 in FIGURE 3;

FIGURE 5 is an end elevational view of one of the wedges;

FIGURE 6 is a vertical sectional view taken on the line 6-6 in FIGURE 5;

FIGURE 7 is a front elevational view of the sill; and

FIGURE 8 is a vertical sectional-view taken substantially on the line 8-8 in FIGURE 7.

Similar characters of reference designate similar or identical elements and portions throughout the specification and throughout the different views in the drawing.

Referring now to the drawings in detail it will first be noted that this assembly includes a sill generally indicated at 10, a pair of wedges, one of which is shown at 12 and a threshold 14.

The environment Wherewith this invention will be used includes a door, ordinarily an inwardly swinging door, with a door frame, the door being indicated at .16 and the door frame at 18 in FIGURE 1. Finish flooring 2i) and rough flooring 22 are also indicated fragmentarily in FIGURE 1, it being noteworthy that tile or carpet will in some cases be added to the structure shown. Wall structure 24 is indicated fragmentarily in FIGURE 2.

Coming now to a more particular description of the sill per se, it will first be noted'that this sill is of slab form with a vertical face 26 at one longitudinal edge of the slab, the sill being generally rectangular in plan form. The sill has a horizontal base 28 and a sloping upper face '35), with a vertical faceplate 32 at what may be considered the outer edge of the sill. This vertical faceplate 32 depends below the adjacent portions of the sill and terminates in a drip edge 34. Channels 36 are formed in the underside of the sill, in that portion of the sill remote from the faceplate 32. Rows of bores 38 are provided in lateral edge portions of the sill, as best illustrated in FIG- URES 7 and 8, and a watershed lip 40 extends upwardly from the upper face 30, as indicated in FIGURES l, 2, 7 and 8, the face of this lip 40 being co-planar with the above mentioned vertical face 26 at that edge of the sill.

A pair of wedges will ordinarily be used with the sill 10, each wedge having a body portion 42 which is tapered throughout its length and a grooved portion 44 is provided adjacent the end of the wedge which will be disposed inwardly of the assembly, this groove portion fitting over the watershed lip 40, and each wedge has an end plate 46 which extends vertically downward to provide a finish face for the assembly, this being particularly valuable when the assembly is used, as indicated in FIGURE 2, for a window sill. A plurality of bores 48 are provided in the body portion 42 of each wedge, these bores 48 registering with the bores 38 of the sill.

Corning now to the threshold, this element will be seen to include a tread 50 having portions 52 and 54 extending horizontally beyond a neck 56 which connects the tread with the base of the threshold, this base being constituted of a pair of parallel legs 58 and 60. These legs are 'each arcuate in cross-sectional shape and are spaced widely apart to provide stability to the threshold. The leg 58 is considerably shorter in its effective vertical dimension than is the leg 6d. This difference in the vertical dimensions of the legs enables the user to use the threshold with finish floors of different thicknesses. For example, when the finish floor 20 is relatively thick, the shorter leg 58 is disposed inwardly of the opening, the longer leg 60 then resting on the inclined surface of the sill and the tread surface being disposed in horizontal position alternatively, when the finish floor 20 is of lesser vertical dimension, then the threshold is reversed, end to end, and the shorter leg 58 is disposed outwardly of the opening to compensate for the lesser of the finish floor.

It is an important feature of this invention that the extending port- ions 52 and 54 are selectively engageable with an interlocking type resilient bottom weather strip 62, such as is now commonly required for doors in exterior openings. These interlocking weather strips are ordinarily secured by nails, such as that indicated at 64 on the bottom edge of the door 16. Channels 66 are provided, adjacent the neck 56, in the threshold, the highest portions of the legs 58 and 60 being slightly above the corresponding bottoms of these channels 66, so that moisture draining down from the door 16 and following the interlocking weather strip 62 will collect in the channel 66 disposed inwardly of the door opening. Drainage apertures 68 are provided in the neck 56 to communicate with the corresponding channels 66 and the space between the legs 58 and 60, and bafiies 70 are formed integral with the neck portion to direct water from the drainage apertures 68 toward a limited area substantially midway between the said legs. Weep holes are provided in the lower edges of both legs, and water reaching the above mentioned are between the legs and will gravitate through these weep holes and escape onto the upper surface of the sill 10.

It should be particularly noted that the water shed lip 40 is disposed on the upward or inward side of the corresponding baffle 70, in all cases, so that this watershed further insures that no drainage will find escape toward the building.

When installing, the sill and wedges are secured by wood screws 74, or the like, and inserted through the bores 38 and 48, into the lower ends of the frame elements of the opening, afterwards the frame elements with the parts attached are slid into place. In attaching the threshold, holes are bored through the tread and wood screws of the like are used to hold this element in place.

The operation of this invention has been referred to in some detail during the foregoing description of the mechanical details thereof, and further description would appear to be unnecessary. It is obvious that all the objects set forth in the preamble to this specification are amply achieved by this invention.

Minor variation from the form disclosed herein may be resorted to without departure from the spirit and scope of this invention and what I claim as new and desire by Letters Patent is:
