poration of Iowa 16 Claims.

An object of our invention is to provide an improvement in the design and arrangement of parts constituting a door frame or similar construction, especially for building openings, the improvement involving parts of comparatively simple design, which facilitate assembly of such a frame, especially an entrance door of ornamental construction.

Another object is to provide a construction so designed that a large number of different entrances can be assembled from a minimum number of standardized parts.

A'iurther object is to so arrange the standardized parts that doors of different sizes can be tted into an assembled entrance frame or building openings of various sizes can be accommodated.

A further object is to provide different designs of vdoor entrance casing parts, such as various kdesigns of pilasters, architraves andcaps, which can be assembled for several different sizes f- `doors without changing to different sizes of pilasters, architraves and caps.

A still further object is to make a frame of standardized parts which is adaptable to wall structuresof different types and thicknesses, a sub-jamb of the necessary width being provided to accomplish this object, in cases where the Wall is of greater thickness than the width of the jamb will accommodate.

Another object is to provide for making up door entrances of various dimensions from a minimum number of parts in stock, and thus do away with the expensive method heretofore used in making up entrances to order in small quantities, and consequently at high cost to meet the varying and multitudinous demands of builders.

One of our principal objects, therefore, is to provide the building industry with an improved frame for building openings, the parts of which can be machined and prefabricated inl large quantities of like parts, so that the cost oi production can be reduced and the selling price to builders reduced, thus resulting in an increase in sales, whereby production can lfurther be increased and still lower cost obtained.

A further object is to provide a door frame construction including side and head architraves of substantial width, which are overlapped by pilasters and a cap, the degree of overlapping beingrvariab-le so that with a pair of pilasters of one length and a cap of one length, a number of diierent 4sizes of door openings (either standard or odd sizes) can be formed as desired, the pila'sters having separable base members whereby the lower ends of the pilasters can be cut off on the job and the base members then applied to finish out the `ornamental appearance oi the pilasters.

A still further object is to provide parts of a door frame so constructed that a minimum of cutting and fitting is required to utilize the parts for diierent sizes of door openings.

Still a further object is to provide pilasters, caps and the like arranged around an opening in a building wall and supported in spaced relation to the wall,architraves or other ornamental members being provided to cover the portion of the wall intervening between the boundary of the opening and the inner edges of the pilasters and caps.

Still a further object is to provide such architraves so that they can be joined to the edge of an opening-defining member, such as a jamb, and have variable joint connection with the pilasters and cap, whereby their degree of reveal can be varied to accommodate different standard sizes of openings and/or compensate for variations in the installation of jamb members.

With/these and other objects in view, our invention consists in the construction, arrangement and combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in our claims and illustrated in the accompanying drawings, in which:

Figure 11 is a front elevation of a door frame embodying our invention showing the parts assembled for minimum door width and illustrating in dotted lines the relative positions of these parts for two other widths of door openings..

On the accompanying drawings, we have used the reference numeral III to indicate a door sill. Side jambs are indicated at I2, and a head jamb at I4. The parts of the door frame construction include side architraves I6, a head architrave I8, pilasters 24J and a cap 22.

Base mold members 24 are provided for the lower ends of the pilasters 20, and the pilasters are usually provided with casing members 26 to overlap the walls. At 28 we illustrate an apron for depending from the sill. In Figure 7 the sill I8 is shown in top plan view, the side jambs I2 being shown in elevation as viewed from the center of the door frame, and the head jamb I4 is shown in bottom plan view.

The side jambs I2 are dadoed at their lower ends as indicated at 30 to receive the ends of the sill I0. The head jamb I4 has each end dadoed at 32 to receive the upper ends of the side jambs I2. The sill I0 and head jamb I4 are supplied of the proper width for the door opening, but the height of the door opening can be varied by cutting off the upper ends of the side jambs at 34 or 36, depending on the height of the door to which the frame is to be adapted. The side architraves I6 are also adapted for being cut 01T at 3B or 40 to properly t the side architraves t0 the side jambs.

The pilasters 2U are also adapted for cutting off at 42 or 44, while the casing members 26 are adapted for cutting off at 46 or 48 to correspond with the lengths of the side architraves I6. The cap 22 is furnished in one length and overlaps the upper edge of the head architrave I8, the pilasters 20 overlapping the outer edges of the side architraves I6.

In order to provide uniformity in the appearance of the entrance, the head architrave must project downwardly from the cap the same distance that the side architraves project inwardly from the pilasters. One end of the head architrave can be cut as indicated at 50, 52 or 54, to thus fit the width of the door opening determined by the lengths of the sill I0 and head jamb I4. The cuts from 36 to 54 are all performed on the job, the parts II), 28, I4 and 22 being furnished of proper length.

By the use of the foregoing described parts, we are able to provide for a great number of different door widths, and heights, which is best illustrated in Figures 1, 2, 3 and 11. In Figure 1 we illustrate the greatest height provided by the pilasters 20 in their original length, and for an intermediate width by projecting the head architraves I8 to an intermediate position as shown in Figures 1 and 4.

In Figure 3 we show the head architrave in the minimum projected position, and in Figure 2 to the maximum projecting position, thus reducing the height of the door considerably relative to the pilasters.

In Figure 2 We show the pilasters out at 42, while in Figure 3 we show them cut at 44 (see Fig. 7), thus accommodating an intermediate and a short height of door respectively.

Obviously with three different widths and three different heights possible with one set of frame members, nine different sizes of doors can be accommodated, whereas formerly each size of door had to be produced individually with the parts cut to the proper length for the size of door to t in the frame being ordered.

Although we have illustrated merely three different widths and heights, it is obvious that a greatnumber of different widths and heights within the range of the particular set of frame parts supplied is procurable.

In Figure 11 we have shown somewhat diagrammatically how the architraves I3 and I8 may be varied in position relative to the pilastersv 20 and the cap 22 to secure three different widths of door openings, retaining the same heights of openings. Surface contour lines of the preceding figures have been omitted from this gure to avoid confusion in the showing of dotted positions. In full lines the minimum width opening is illustrated, and it will be noted that the side architraves I6 project the same distance from the pilasters 20 that the head architrave projects from the cap 22. The head architrave for the minimum width (full line) position is cut at the line 54 in Figure 7.

To secure an intermediate width of opening, the side architraves are moved outwardly to the position indicated at ISa by dash lines. The head architrave I8 must similarly be moved upwardly to the position at I8a to project the same distance from the head architrave that the side architraves do from the pilasters. For this position the head architrave is cut at the line 52. Similarly the dotted positions at 16h and I8b are assumed by the architraves for a still widerl door opening, the head architrave being cut on the ,i

line 50 for this purpose.

Since the side architraves I 6 are made for a doorl opening of given height, the height of this opening will remain the same in the three illustrated positions of the architraves but the width Y will vary. For making shorter door openings, the side architraves can be out at 38 or 4U, and the pilasters at 42 or 44, the casing members 26 being correspondingly cut at 46 or 48.

By providing the base member 24 as a separable part, the bottom ends of the pilasters can be cut oil square without any necessity for intricate fitting or reforming the pilaster base or the like. Our construction also provides for cutting ofi` the lower ends of the side architraves and the upper ends of the side jambs squarely, the only mitered joint being necessary being the one at 5U, 52 or 54 on the head architrave;

In Figure 4 the head architrave is projected to an intermediate position. This intermediate position for the side architrave is shown by dotted lines in Figure 6, the solid line showing being for the minimum projection, and the dash line showing for the maximum projection. It is obvious that by providing the architraves of substantial width, such variation is permissible, more or less projection merely resulting in less or more space indicated at Strand 58 in Figures 6 and 4 respectively.

The side architraves I6 are applied to the outer edges of the side jambs I2, as shown in Figure 6, for a wall 60 of minimum thickness. The head architrave is positioned against the wall, and the cap 22 against the head architrave as in Figure 4, a iiller block 62 being used to space the extension head jamb 68 are used.

.upper edge of the cap, Whereas the casing memrv`ber I26, shown in Figure 6, accomplishes a similar .purpose for the pilaster.

Where a wall construction is thicker, such as a masonry wall 64, as shown in Figures 8 and 10, a sub or extension side jamb 66 and a sub or These may varyin width, wider ones being used for thicker walls and vice versa. These are preferably provided with tongues 10, which fit into grooves 'l2 in the outer edges. of the jambs I2 and I4, to provide a weather-.tight connection at this point. The architraves are then applied to the outer edges of the sub-jambs.

\Byvthe use of our door frame construction a great number of different sizes of door openings can .be provided with one set of frame parts and manufacturing and installation variations can rbe compensated for. The only variation in appearance of the various sizes of door frames. is inthe relative degree of extension of the architraves from the pilasters and cap. The architraves are preferably provided with longitudinal ornamentations such as moldings and grooves as illustrated particularly in Figures 6, 9 andlO, some of which, in the minimum extension of the architraves, are concealed, but which are apparent when the architraves are extended so that in any extended position of the architraves relative to the pilasters and cap, the ornamental appearance of the door frame is not detracted from.

The side casings 26, it will be noted, extend beyond the upper ends of the pilasters in Figure '7. In -Figure 8 these are shown extending up behind Vthe ends of the cap, thus providing additional engaging surfaces to be nailed together for effectively-securing the cap relative to the other frame parts.

.The inside of the door opening may beI trimmed inany of tlie usual methods, comprising interior .trim such as indicated at '14, plaster returns or the like.

From the foregoing it is obvious that one of the essential features of our invention is the movability of architraves or the like relative to pilasters, caps or the like to take care of different sizes of building openings without however using different sizes of pilasters and caps. Adjustment `is possiblel without opening up any joints or otherwise complicating installation of the frame relative to the building opening. i Although we have shown one ornamental type ofpilaster and cap, it is obvious that pilasters and caps can be made in other shapes or contours, and other changes also may be made without departing from the real spirit of our invention, and it is our intention to cover by our claims any modied forms of structure or use of mechanical equivalents which may be reasonably included within their scope.
