UNITED. STATES PATENT OFFICE FORM APPARATUS FOR WALL OPENINGS Joseph Banneyer, Chicago, Ill. Application May 26, 1948, Serial No. 29,293

5 Claims. 1

This invention relates to formapparatus for wall openings. The invention is particularly useful in the construction of concrete walls, etc. and in the forming of window frames, door frames,

and other frames for wall openings.

An object of the invention is to provide form apparatus which may be brought together for quick assembly and disassembly and employed for the forming'of wall-opening frames in wall openings, such as, for example, window and door openings, etc. still another object is to provide form apparatus readily applied to wall-form openings for closing the space between the walls and for supporting wall-opening frames and for adjustably supporting said frames within the wall space. A still further object is to provide, in combination with panel structure for forming walls and having openings therein, form apparatus for sealing the space between the walls about said openings and for receiving the wall -opening frames, means being provided for adjustably supporting said frames within the area to be filled by concrete, etc. 'Otherspeciflc objects and advantages will appear as the specification proceeds.

The invention is illustrated, in preferred embodiments, by the accompanying drawing, in which- Figure 1 is a side view in elevation of form apparatus embodying my invention; Fig. '2, an enlarged broken view in elevation of a portion of a window frame to be secured within a concrete wall, etc; Fig. 3, a, broken side view in elevation of a portion of a door frame or jambp 1 liigv 4, a transverse sectional view of a portion of the wall-form structure about the concrete wall and showing the formmechanism for supporting a window frame within the concrete wall,

etc. and Fig. 5, the concrete wall equipped with l the window frame, the been removed.

In the illustration given, I Udesignates a number of panels formed of steel, aluminumjorother form apparatus having suitable materials, having outwardlyextending will be understood that any suitable form apparatus may be employed for the forming ofthe spaced walls between which the concrete is to be poured. v

The wall-form structure illustrated leaves on one side an opening indicated by the numeral 14,

which is adapted for use as a window opening, and another opening I5, which is adapted for use as a door opening.

In forming the window opening I4, as shown more clearly in Fig. 4, the adjacent panels In terminate in outwardly-extending flanges ll. Abutting the flange M on each wall is a form member IS. The form member l6 has an outwardly-extending flange resting against flange H and a rearwardly-extending ledge parallel with ledge [2. Each form it extends inwardly, and then is turned sharply to the rear to provide a guide wall [8. The two guide walls I8 of the two members M, as shown more clearly in Fig. 4, provide between them a channel I9, in which is mounted the form frame 20. The form frame 20 is fixed to the channel walls ill by means of bolts 2|.

Any suitable means for securing the flanges of form members It to the panel flanges it may be provided. As shown more clearly in Fig. 4, C clamps I3 may be employed for this purpose.

The frame members 20 are provided, at spaced intervals, with guide rojections 22, also enclosed within the channel walls l8. Guided between the members 22 and between the channel walls l8 are the shoes 23. Shoes 23 may be provided, if desired, with grooves 24 adapted to receive the tongues 25 of the window frames 26. The window -'through the frame 20 in threaded relation therewith and may bear within a recess in the shoe 23. 'If desired, a ring 29 may be provided for locking the end of the screw within the recess of the shoe 23.

To advance or retract the shoe, the bolt 28 may be turned, and for this purpose, the bolt is provided with a head 30. It will be understood that other equivalent means may be employed for this purpose.

For closing the space between the walls forming the door opening [5, I provide a similar frame structure 3| of the shape suitable for a door frame and equipped also with tie members 32, as shown more clearly in Fig. 3. I provide forms I600 similar to form I6 and providing a similar channel receiving the door frame 3|. Within the channels are mounted shoes 33 which engage the side frames or jambs of the door and are supported by means of a turn-buckle 34. The shoes may be located at the extreme ends of the openings in the frame Isa so as to support the top and bottom frame portions, as well as the side frame portions, as shown more clearly in Fig. 1. By adjusting the central threaded sleeve 35, the shoes 33 may be moved outwardly or inwardly. Thus, there is provided a ready means for adjustably supporting the door frame within the space between the walls which is to be filled with concrete. The adjustment means described are merely illustrative of various types of adjustable supports which may be employed for holding the door frames and window frames in the desired position within the space to be filled by concrete and against the pressure of the concrete or other material to be cast.

After the concrete, etc., has been poured into the space between the walls, and after the poured walls have cured, the C clamps [3, or other clamps employed, may be readily removed, and the forms .stripped away. The bolts 28 may be retracted .to separate the shoes 23 from the frame 26, and

likewise the shoes 33 may be retracted and the :formsymay be lifted away. In the removal operation, the nuts of bolts 2! may be removed, and the forms it removed. The apparatus permits ready assembly and disassembly, and provides accurate means for adjusting the frame members within the wall opening so as to seal the space about the wall-opening frames. After the removal of the form apparatus, the frame will be embedded in the wall structure, as illustrated in Fig. 5.

It will be understood that in many cases, the window itself may be held in the form and abutting the window frame 26, and in this structure the members 2n. and 23 would be omitted.

While in the foregoing specification, I have set forth specific apparatus in great detail for the purpose of illustrating an embodiment of the invention, it will be understood that such details of structuremay be varied widely by those skilled in the art without departing from the spirit of my invention.

I claim:

3.. In form apparatus useful for the casting of a wall about a wall-opening frame, a pair of panel walls apart to receive cast material therebetween and enclosing the side walls of the wall- 1 opening frame and providing further a channel extending inwardly of the frame, a form frame in said channel and fixed thereto, pressure shoes in said channel and adapted to bear against said wall-opening frame, and threaded rods extending through said fixed form frame and engag- "ing said shoes to advance and retract them.

2. In form apparatus useful for the casting of a wall about a wall-opening frame, a pair of panel walls spaced apart to receive cast material therebetween and enclosing the side walls of the 6 wall-opening frame and providing further a channel extending inwardly of the frame, a form frame in said channel and fixed thereto, pressure shoes in said channel and adapted to bear against said wall-opening frame, said shoes and said wall frame being provided with interlocking surfaces to prevent relative movement of the shoes and wall-opening frame when the same are frictionally engaged, and threaded rods extending through said fixed form frame and engaging said shoes to advance and retract them.
