Claims.

The present invention relates to door constructions in general and more particularly to an improved door of the type including a wooden frame which is either partially or wholly encased in metal.

An object of the invention is the provision of a door of this character wherein the metallic covering for the wooden frame is composed of extruded metal strips of substantially channel formation associated with and secured to the wooden frame in such a manner that the securing means for said metal strips are not visible when the door is closed.

Another object of the invention is the provision of a door of this character including means for loosely connecting the extruded metal Strips at their adjacent ends in a manner to permit relative expansion and contraction between the wooden frame and metallic covering therefor at the corners of the door.

A further object of the invention is the provision of a door of this character of neat, attractive appearance, which is extremely easily and simply fabricated, and which is provided with novel means for readily and conveniently mounting a pane of glass therein.

A still further object of the invention is the provision of means for mounting a pane of glass in the door so constructed that the securing means therefor are positioned upon the inside of the door and inaccessible from the outside when the door is closed.

Other objects and advantages of the invention will become more apparent during the course of the following description, when taken in connection with the accompanying drawings.

In the drawings, wherein like numerals are employed to designate like parts throughout the same:

Fig. 1 is a front elevation of a door construction provided by the invention;

Fig. 2 is a vertical transverse section through the door taken substantially on line 2-2 of Fig. 1 with the transom bar and door frame removed;

Fig. 3 is a horizontal transverse section taken substantially on line 3 3 of Fig. 1;

Fig. 4 is a horizontal transverse section taken substantially on line 4-4 of Fig. l;

Fig. 5 is an enlarged sectional view of the mounting for the pane of glass; and

Fig. 6 is a detail section taken substantially on line 6-6 of Fig. 1.

In the particular embodiment of the invention disclosed in the drawings, as illustrative ofv one form which the present invention may take,

there is shown a so-called entrance type of door including the door proper I0 above which is arranged the transom II. The-door I0 and transom I I are mounted in the customary door .lamb including the vertical side members I2 and I3 and the horizontal head member I4. Arranged between the top of the door I0 and bottom of the transom II is the usual transom bar I5.

The doorv II) comprises a wooden frame of the desired shape and size including the vertical stiles I5 and Il and the horizontal top and bottom rails E8 and I5 suitably connected together at their adjacent ends to form a substantially rigid frame. rfhe outer surfaces of the wooden stiles I6 and I1 are covered by metallic strips 2I and 22 respectively provided with rearwardly directed

flanges

23 and 24 which overlap the opposite side edges of said stiles as best shown in Fig. 3. The opposite side edges of the stiles are preferably notched as at 25 and 26 to receive the flanges 23v and 24 respectively of the metallic strips. It will thus be seen that the strips 2I and 22 are of substantially channel formation and they are preferably formed of extruded metal such as aluminum of relatively heavy gauge. The metal channel strips are secured to the wooden stiles by screws or the like 21 which pass through the

flanges

23 and 24 thereof.

The top rail I8 of the wooden frame also has its outer surface covered with a similar metal channel strip 28 and this strip is provided with rearwardly turnedflanges 29 and 30 which overlap the upper and lower edges of the rail and are secured theretoY by screws or the like 3I. The meeting ends of the vertical channel strips 2| and 2.2 covering the wooden Stiles I6 and II and the horizontal channel strip 28 covering the wooden top rail I8 are preferably mitered at their adjacent ends as at 32 and 33.

The bottom rail I9 of the wooden frame is here shown as being considerably wider than the top rail I8 andV is covered by the upper and lower

horizontal angle strips

34 and 35 also preferably of extruded metal and spaced from one another to receive therebetween a metal kick plate 36. The upper angle strip 34 is provided with an inturned ange 31 which overlaps and is secured to the upper edge of the bottom rail by screws or the like 38, while the lower angle strip 35 is provided with an inturned flange 39 overlapping the bottom edge of the rail and secured thereto by screws or the like 40.

The inner adjacent longitudinal edges of the

angle strips

34 and 35 are spaced from one another as best shown in Fig. 2 and are formed with grooves 4I and 42 respectively within which the kick plate 36 is slidably received. The inner adjacent marginal edge portions 43 and 44 of the

angle strips

34 and 35 overlap the front surface of the kick plate while the said strips are also formed, in back of the kick plate, with

plate portions

45 and 46 respectively secured to the rail by screws or the like 4'I. 'Ihe kick plate 36 and

plate portions

45 and 46 are preferably set into a recess 48 in the front surface of the wooden rail I9.

In the construction of the door, the inner flanges 24 of the metal channel strips 2l and 22, covering the wooden stiles I6 and I'I, extend from the top of the door down to the top of the bottom rail I9 only, while the strips 2| and 22 and outer flanges 23 extend downwardly to the bottom of the door as shown in Fig. 1, with the said strips overlapping the opposite end edges of the kick plate 36, as shown in Fig. 4. Those portions of the metal strips 2| and 22 extending beneath the bottom rail I9 can be secured to the wooden stiles I6 and Il by screws or the like 49 passing through anges 23. The lower ends of the metal strips 2l and 22 and opposite ends of the metal angle strip 35 are mitered as at 50 and 5I.

To provide for relative expansion and contraction between the wooden frame and the metal covering therefor at the corners of the door, there is provided at each of said corners a substantially H-shaped strip beading 52 (Fig. 6) also of metal. This beading is provided with two oppositely disposed grooves 53 and 54 adapted to loosely receive the adjacent ends of the respective metal strips. The beading 52 is not secured to the wooden frame but simply fits in a recess 55 therein. Consequently, upon relative expansion and contraction of the wooden frame and metal covering, the meeting ends of adjacent metal strips are free to move inwardly or outwardly within the grooves 53 and 54 of the beading 52.

The door is also provided with a window 56 consisting preferably of a sheet or pane of glass mounted in the door by means of a metal frame including the top and bottom sections 'I and 58 and side sections 59 and 66. Since all of the metal frame sections are of the same construction, a detailed description of only one will be given. As best shown in Fig. 5, each metal frame section comprises an outer member 6I and an inner member 62. The outer member 6I includes a front portion 63 extending substantially parallel with the glass sheet 56 and a base portion 64 extending rearwardly at right angles thereto and beyond the edges of the pane of glass. The base portion 64 is secured to the inner edge of the respective stile or rail of the Wooden frame by screws 65, while the front portion 63 is preferably provided along its outer edge with a bead 66 engaging the outer surface of the glass sheet. The front portion 63 of the outer member 6I is also provided with a forwardly directed flange 6'I of any desired profile. 'I'his flange 6'I not only forms an ornamental molding or edging but also serves to cover the attaching screws 38 for the metal angle strip 34.

The inner member 62 comprises a rear portion 68 provided along its outer edge with a bead 69 engaging the inner surface of the glass sheet '56. The inner member 62 is also provided with an inwardly turned base portion 'I6 which rests upon the base portion 64 of the outer member 6I and is secured thereto by screws 'II. rl'fhe base portion 'I0 of the inner member is preferably provided with transverse slots 'I2 through which the screws 'II pass. This permits the inner member 62 to be moved inwardly or outwardly to accommodate glass sheets of different thicknesses. When installing the window, the outer members 6I are rst secured in place. The pane of glass 56 is then positioned to engage the beads E6, after which the beads 69 of the inner members 62 are moved into contact with the inner surface of the glass sheet and the screws 'I I' put in place and tightened.

The transom II may be and preferably is of substantially the same construction as the door I il and also includes a window 'I3 mounted in the same manner as the window 56 is mounted in the door. The transom comprises a substantially rectangular wooden frame including the top and bottom members 'I4 and l5 and similar side members (not shown). Each of the members of the wooden frame has its outer surface covered by a metal channel strip '16, the inturned flanges l1 and 'I8 of which overlap the edges of the frame member and are secured thereto by screws or the like 79. The meeting ends of the channel strips 'I6 are also preferably mitered as at 66 and may be secured together by metal strip beading such as shown in Fig. 6. The pane of glass 'I3 constituting the window may be secured in the transom frame by means of a metal frame mounting including the top and bottom sections BI and 82 and side sections 63 and 64. Since the metal frame sections are the same as illustrated and described above for mounting the pane of glass 56 in the door, it is not believed necessary that they need be described in detail.

As brought out above, the metal strips used for covering the wooden frame of both the door proper I0 and transom II are of extruded stock,

.preferably of relatively heavy gauge, which results not only in a stronger, more durable construction, but also in a door of pleasing, attractive appearance. It will of course be appreciated that while only the front faces and approximately one-half of the side edges of the wooden frame members have been illustrated as being covered, the wooden frames may be entirely encased with metal if desired. Also, if preferred, the kick plate 36 may be omitted, in

which case the angle strips 34 and 35 could be made integral with one another in the form of a single channel strip. By securing the metal covering strips to the wooden frame members in the manner disclosed, the securing means for said metal strips will not be visible when the door is closed. Likewise, `the fastening screws 'II of the metal frame mounting for the pane of glass 56 are positioned upon the inside of the door and in this way prevent removal of the glass from the outside.

It is to be understood that the form of the invention herewith shown and described is to be taken as the preferred embodiment of the same, and that variousv changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.
