Filed March 27, 1952 2 Sheets-Sheet 2 United States Patent DOOR Joseph Sylvan, Berkley, Mich.

Application March 27, 1952, Serial No. 278,873 7 claims. .(Cl. zii-3s) This invention relates Ito a `metal clad door and particularly .to adoor .comprising a wood frame having metal sheets secured to opposite sides thereof and .metal channels embracing the outer 1margins yof the door overlapping the metal sheets.

Heretofore, metal vclad doors :of this `type have been fabricated according to the .disclosure of my Patent No. 2,582,467. These doors were .provided .primarily as storm doors and consisted of .a wood frame covered with sheet material.

Such .patented door had .a wood frame composed of two upright wood Stiles connected at .the top `by a wood header and elsewhere .connected by Wood cross frame members spaced vertically from `the header. The header, the two Stiles, and one wood cross frame member .delined a'window opening. Metal sheets `were secured Eto opposite sides .of :this frame completely covering the wood frame and secured thereto by nails or the like. Sheet metal channels embraced the Aouter margins of the .door and gripping-ly .engaged the metal sheets.

It has been found under certain conditions that .certain portions of the wood frame tended to shrink following the fabrication of the door. As an example, a stile member alongside the window .opening might shrink. Inasmuch as 'the metal plate was secured ,adjacent .to both margins of the -stile member by a row of nails, such shrinking might result in -buckling of .the metal plate.

This invention relates to a door which is so .constructed that shrinking or contracting of portions of the wood frame member will not result in buckling of the overlying metal sheets. The wood frame is lso constructed, and the metal sheets so secured thereto that shrinking of the wood iframe underneath the metal sheets may voccur without any resulting undesirable buckling of the sheets.

A further meritorious 'feature of the door of this invention is that the construction is such ythat any change in dimension of a portion of the wood frame withinthe metal sheathing 'will not result in such undue pressure being put upon the fastening means as to loosen such means which attaches the metal sheets to the frame. Whether such change in dimension is one of contraction or expansion, the instant `construction can be accommodated to take care of it without any loosening of the fastening means or buckling `of the sheet materia-l.

Other objects, advantages and meritorious features of the invention vwill more fully appear from the following speciiicat-i0n,claims and accompanying drawings, wherein:

Fig. l is a-n .elevation of a door embodying my invention with aportion of one metal sheet broken away to illustrate lthe wood frame;

Fig. 2 is a vertical sectional View taken on the line 2-.2 of Fig. l;

Fig. 3 is a vertical sectional view taken on .the line .3 3 of Fig. 1 and being broken yaway and enlarged;

Fig. 4 is an elevation of a fragment -o-f 'an upper corner of the door shown in Fig. l with part of the overlying metal sheet removed and with the wood frame partly broken away;

Fig. 5 is va view 'taken -on the same sectional line vas Fig. 2 but showing the shrinking of a .portion of the wood frame between the overlying metal sheets;

Fig. 6 is a transverse sectional view taken on the line 6-6 of Fig. l;

Fig. 7 is a transverse enlarged sectional view taken along line 7-7 of Fig. l;

Fig. 8 is an elevation of a door of a slightly modified form as compared with the door lof Fig. .1;

Fig. 9 is a transverse sectional view taken on the line 9-9 of Fig. 8.

Considering the door of Fig. l, there is a wood frame which consists of 4a pair of upright 'wood stiles indicated at Figs. l and 6. These lstiles are connected together at 2,694,236 Patented Nov. 16, 1954 ICC the bottom by `a cross .frame member 12 (Figs. l and 3)., and at the top by a .cross frame member 14 (Figs. 2 and 4). The bottom cross frame member 12 and the top header 14 are secured by nails or the like 16 to the ends of the Stiles 10. A second cross frame member 16 is shown in Fig. 3 and this rcross frame member connects the two stiles together `just below the window opening. These three

cross frame members

12, 14 and 16 and the two -stiies 10 form a wood frame for the door..

A pair of .meta-l plates 18 cover that portion of the door below the window opening and are secured to the cross frame members 12 and 16 :and the stiles 10 by nails 20 or the like. A pair of metal plates 22 as shown in Figs. 1., 6 A.and 7., .cover each of the two upright stiles lill and are Isecured thereto by nails 24 or the like .as shown in Figs. 6 and 7.

A pair of metal plates 2.6, as .shown in Figs. l, 2 and 5., cover the .header 16 on opposite sides and are secured thereto by nails 28 or the like.

The door be provided with suitable hinges 30 and a door latching arrangement 32, each of which has nothing to do with the invention.

Metal channels 34 extend along and over and em-v bracethe outer margins of the door frame and overlap the metal sheets disposed on opposite sides thereon. One

such channel 34 is shown as extending along over the top margin of the header 14 in Figs. 2 and 5. Another such channel 34 is shown as extending along over the bottom margin of the bottom cross member 12, as shown in Figs. l and 3. Two other such channels 34 are shown extending along `over the outer margins of the stiles in Figs. l and '6. The side walls of these channels grippingly engage `the metal sheets. The side Walls of these channels extend yover and beyond the row of securing means .or nails which Asecure the sheets to the `vvood frame, all as shown in the several figures referred to hereinabove.

Furthermore, [the metal sheets themselves are shown as terminating spaced inwardly of the outer margin of the wood .frame whether along the outer margins of the stiles or :along the top `margin or the bottom margin of the frame. Generally, the above is all shown and described in a manner above heretofore referred to.

The wood frame of the instant Aconstruction however differs from that of the patent referred to. In the in. stant wood frame, each of the stiles 10 is shown as provided with or including a separate Wood strip 38 which eX- tends along the inner .margin of thev stile .and may be secured thereto by connecting mearm such as nails 40. These nails 40 are driven .through the strip into the main body of the wood .sti-le, but the strip is separable to be moved relatively toward or .away from .the main body of the wood stile by partial withdrawal ofthe nails there` from. Such a wood strip also is shown as extending along theheader 14. Such strip is there indicated by the numeral 42 .and the strip 42 is shown as secured to the inner margin of 'the header by the :nails 44. Such strip is relatively shiftable with respect to the header toward or away therefrom by partial Withdrawal of the nails from the main body of the header.

The lower margin of the header 14 is ycovered by a metal channel 48 which extends therealong embracing such lower margin as shown in Figs. l, 2 and 5. This channel exhibits a downwardly opening header channel 50 adapted to receive the upper edge of a framed glass pane 52, as shown in Figs. l, 2 and 5.

The opposed inner margins of the stiles are provided with lmetal channels S4 which extend therealong and er brace the same. t ese channels extend inwardly over the nails Lt-il which connect the plates 22 to the strips 38. Each of these channels has an inwardly projecting lip 56 adapted t `serve to hold the window pane in place. The cross frame member 16 has a metal channel 58 extending 'aiong over and embracing the upper margin and overlying the metal plates lb, as shown in Fig. 3. This metal channel is provided with an upright liangc 60 which serves as an abutment for a framed window pane 54.

qWhile kiln dried wood is used to fabricate `the wood frames, such wood pieces 4are not .always thoroughly dried. They may pick up moisture during shipping, storage or fabrication. Whe-n the metal plates are secured thereto,

as for example, the metal plates 26 are secured to the header 14, such plates will be secured along their upper margin by a row of nails extending along adjacent to the upper margin of the header. The lower margin of this header is formed by the separate strip 42 which is secured to the edge of the main body of the header by nails 44. The metal plates 26 are secured to this strip 42 along the lower margin of such plates by nails 58. If the header shrinks the metal plates being secured along their top margins to the main body of the header 16 and secured along their bottom margins to the separate strip 42 permit such shrinkage as the nails 44 to withdraw partially from the main body of the header. The wood frame is suiciently protected by the metal sheathing as to substantially eliminate any accumulation of moisture which would produce expansion, but if the material were thoroughly dehydrated at the time of fabrication of the wood frame, and if there were any likelihood of moisture accumulation by the frame, the construction could be initially set up as shown in Fig. 5 and thereby expansion of the wood frame would be provided for.

In Figs. 8 and 9, a modied form of door is shown as compared with that of Fig. 1. In these Figures 8 and 9, two large window panes are shown. The intermediate cross frame member is omitted. The frame consists of the two stiles, a header and a bottom cross frame member. Metal plates are secured to opposite sides of the Stiles and the opposite sides of the header and bottom cross frame member. The construction of the stiles with the separate wood strips is as shown in Figs. 6 and 7 heretofore described. The construction of the header is as shown in Figs. 2 and 5 hereinabove described. The construction of the bottom frame member which is here indicated as 12a is similar. This bottom frame member includes a separate strip 60 which extends along its inner or upper margin and is secured thereto by nails 62. This strip is separable with respect to the main body of the cross frame member 12a. Metal plates 64 are secured to opposite sides of this bottom frame member 12a by nails 66 which extend as a row along the bottom margin into the main body of the frame member 12a by nails 68 which extend as a row along the top margin and to the separate strip 60.

A metal channel 70 is shown as extending along and embracing the inner edge of this cross frame member 12a and provide a seat for the lower glass pane indicated by the letter L. The upper glass pane in this assembly is indicated by the letter U. This channel 70 has an upwardly projecting flange 72 as shown in Fig. 9.

The construction of Fig. l does not show any separate strips on the inner margins of the lower portions of the stiles covered by the metal plates 18 and neither are any separate strips shown on the bottom cross frame member 12, or the intermediate cross frame member 16. This is due to the fact that the metal sheets 18 are not attached at two places to the same wood strip and are therefore free to expand or contract.
