' Referring toFigures 1 to 3 of the drawings,

in this embodiment of the invention, the frame door includes flat side strips 10, and top and bottom strips11- and 12, said strips'being connected at their ends as by welding'to-providea frame portion of rectangular formation. 7 Secured to the side strips 10, by welding or other suitable means, are channel bars 13 and 14, having'their channels disposed inwardly; andv secured-to the top strip"11,'by

provides a recess or groove in continuation of the channels in thebars 13 and 14., A Z-bar- 16 may gbe removably secured to'the strip 12 by means .of counter-sunk bolts 171, this bar also having a recess in continuation ofthe channels in the side bars 13 and 14, so asto b rivets; or other means,-is a Z ba'r 15, which afford a continuous space or groove for the reception of the edges of a' closure, so as to hold and brace the same against lateral move- ;ment,"as wellas endwise movement.

. Diagonally disposed braces 17,- preferably tubular 111 form, may have their ends flattened and secured tothe inner flanges 18 of the channel bars 13 and. 14, and to strips 1'1 and 12, thus bracing thefframe against torsional displacement, and a cross brace 19 may extend between-the channel bars 13 and 14-and besecuredtothe inner flanges 18 d to the said channel bar 14 as shown.

A, closure 20 isshown as disposed within the continuousv space; or guideway (provided by 'the flangesof the channel bars and the removal from said spacebythe attachment or detachment of the Z-bar 16; Bolts 21 a 1 having theirheads counter-sunk, maybe extended through the channel and Z-bars and the edges of theclosure as shown, for addi 1 I tendingaround all'the four edges thereof as clearly indicated in Figures 1 and 2.. It

- lshbllldlbe d o i j he Construction": li de ibed s not mited to 1 wood 101.,

"sures,j'since various metal closures, not ,1

shown, may be fastened to the door frame described. The closure 20 also may be in sections, or a portion of the wooden closure 20 utilized, together with a metal closure for the remainder of the frame, substantially in the same manner as described in my companion application above referred to. cept as defined in the claims I do not wish to limit myself to the use of any particular character of closure with the frame clescribed, nor to a frame which slidably receives the closure throughout the length of the members, although this is an important feature of the invention. In this connection it is obvious that the frame is adapted for use with a great variety of closures'secured thereto in different ways.

By the arrangement just described, there is provided a metal door frame which is braced "against torsional and lateral strain, and is provided with an interior space to receive the edges of the filler or closure, such closure being held in the frame by means of the Z-bar 16, removal of which will permit removal of the closure 20. Of course the bolts 21 are connected and disconnected during these operations, such bolts being provided as additional securing means.

Referring now to Figures 4 to 6, inclusive, a unitary construction is illustrated, substantially of the same character. as that before explained. In this embodiment, the frame comprises the side strips '30. and the top and bottom strips 31 and 32, respectively, as before described. T-bars 33 and 34 are secured to the side strips 30, preferably by welding, and the Z-bar 35 may be secured to the top strip 31 in the same manner, so as to provide the recess 36 at this point. A Z-bar 37 may be fastened to the strip 32 by countersunk bolts 38; so as to be removable when desired. The Z-bar 37 provides a recess for the reception of the adjacent edges. of the closure, and such Z-bar preferably has openings 41, in its retaining flange 42, for the escape of water which might collect in the recess provided by such bar.

Crossbrace strips 43 and 44 are provided atopposite faces on the frame, preferably being secured by welding the end portions thereof to the side bars 33 and 34. Gusset 1, plates 45 are secured at the corners ofthe ard wood door 46, having the usual bracing s'trips 47 on its inner face, such closure being shown as disposed in the frame. Ilhe strip 44 is preferably also secured tothe' member It should be noted with respect to the embodiment of the invention just described, that the side bars 30 are in the form of T-bars, and:

if desirable, I may omit thestrip 44 on theouter face of the frame, so that when the Z-bar 37 is removed, the closure 46 may be disposed broad-side between the T-bars, moved beneath the Z-bar 35, and the Z-bar 37 secured in position, in this way providing for ready disposition and removal of the closure with respect to the frame, the closure being held securely in position by the Z-bars 35 and 37 and in addition bolts, not shown, may be extended through the cross brace 43, and the edges of the door in the manner before described.

It will be appreciated that I have provided a metal door frame having great strength and rigidity, in which the desired closure may be quickly and removably disposed, at the same. time being firmly braced and held in the frame, resulting in a great saving of expense and affording opportunity for convenient and economical re-placement.

I have herein shown and described'what I now consider the preferred manner of carrying out my invention, but the same is merely illustrative, and I contemplate all changes and modifications that come within the scope of the claims appended hereto.
