.To aZZ whom it may concern;

Be it known that I, HENRY MARTEN, a citizen of the United States, residing at Toledo, county of Lucas, State of Ohio, have invented a certain new and useful Improvement in Door-Frames for Cooling-Rooms; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to door-frames for cooling-rooms.

It has for its object an improved frame in which the floor or'sill is on a level with the floor of the interior of the cooling-room, icebox, or refrigerator.

In the drawings, Figure 1 is a perspective showing the frame in position. Fig. 2 shows the several parts which constitute the front of the room. Fig. 3 is a perspective of the frame. Fig. 4 is a front elevation with the door-frame removed.

The front frame of the room or box is made of planking A and B, which may be in any desired number of pieces grooved and united by a tongue 1, which engages in the grooves of adjacent pieces. Behind the planks A and B, which are horizontal planks, are ver tical planks 4 5 6. Through the wall thus formed is a rectangular opening with a deep rabbet extending across the top' and down each side. This rabbet is formed by allowing the lining layer (the Verticals 4 5 6) to extend in, inclosing an opening that is smaller through the lining layer than is the opening through the facing layer of planks. The opening through the facing-plank extends below the upper edge of the floor 16. The side planks 9 10, which stop at the upper edge of the floor 16, and the front surface 162 of the floorplank form the vertical face of a rabbet that extends acrosstheopening at the bottom thereof.

The dotted lines about the door-opening in Fig. 4 indicate the part covered by the frame when in position, and in this view is clearly shown the difference in elevation between the upper edge of that portion of the plank Awhich lies below the door-space and the upper edge of the floor 16. This equals the thickness of the tread portion or facing 178 of the frame, so that when the frame is in osiition this facing and the floor are on a eve The front planks A reach below the upper edge of the floor 16 andengage on a subfloor 14, on which the entire structure rests. On the subfloor 14, in front of the horizontal plank A, is a batten 15. In the rectangular space is placed a rectangular frame 17. The stiles 171 172 of this frame fill the vertical rabbets in front of the faces 7 9 and 8 10, the rail 173 fills the rabbet across the top of the opening, and the sill 174 fills the rabbet in front of face 162 of the opening. The inner faces of the frame are flush with the inner faces which bound that part of the opening that extends through the lining-plank. The facings 175 176 177 178 engage closely against the fronts of the planks A and B, and the opening through the finished wall is without obstruction, and especially is the sill entirely level with the floor of the room.

A door (not shown) closes the opening.

What I claim is 1. In combination with a laminated wall provided with apertures of different size in adjacent layers, and with a floor ortion arrangedto be supported above the foundation-floor portion, there being an air-space therebetween, a door-frame having facingpieces adapted to enga e over theedges of the opening in the outer ayer of the wall, and inwardly-extending portions complementary to said facing-pieces, adapted to occupy the space intervening between the edges of the opening in the outer layer and the edges of the opening in the inner layer of the wall, and to lie with their exposed surfaces flush with the edges of the opening through the inner layer of the wall, substantially as described.

2. In combination with thelaminated front wall of a refri erator-building, a floor portion spaced from t e foundation of the structure, a door-frame set in an opening in said wall, having facing portions adapted to engage over the edges of said opening, and inwardlybeing in the same plane and continuous with extending portions of less depth than the the floor portion, substantially as described. 10 thickness of the wall, the exposed faces of In testimony whereof I sign this specificathree of said inwardly-extending portions betion in the presence of two witnesses.

ing arranged to lie in the same plane with the HENRY MARTEN. exposed edge of the opening through the in- Witnesses: ner layer of the wall, and the exposed edge ERSKINE H. POTTER,
