MOLD FOR RE INFORCEIQ-CONCRETE WALLS.
Specification of Letters Patent. Application filed February 19, 1907.
Patented Aug. 3, 1909. Serial No. 358,279.
To all whom it may concern:
Be'it known that I, GEORGE W. Srnwsn s, a citizen of .the United States, residing at Lynn, in the county of Essex and State of Massachusetts, and useful Improvements in Molds for Beinforced-Concrete lVa'lls, of which the following is a specification, reference being had therein to the accompanying drawing.
My present invention relates to improvements in molds for reinforced concrete walls, and has special reference to a new and improved mold, which is'especially adapted to he used in connection with concrete walls, curbing and other concrete work, the object being to provide a mold sustained from the .inside and which is quickly and readily placed in position and which is built or-as- 1 sembled' as the work 2oprogresses. To attain these ob3ects the lnvention consists of a new and improved construction '01 mold and fram'eas will presently appear.
'In theaccompanying drawings, Figure 1 is a side elevation of a complete mold and the frame thereof, Fig. 2 is a top planthereof, Fig. 3 is a cross section taken on line X-X, of 2. Figs. 4 and 5 are detail views of various parts.
Referring to the drawings :-I employ form boards 1, upon the outer face of which are a series of cleats, 2', whose upper'ends extend above the upper edgeof the form boards as at 3, and provide a means to pre-. vent the lower edge .of which rest upon thclower form boards, from spreadin The upper portion 3, of the cleats is provided with an opening 4, which is adapted to aline with the openm 5 near the bottom of the upper mold, the depth ofthe opening 5 not being the thickness of the board. A threaded rod or bolt 6 is adapted topass through this opening 5* and have a wire 7, which extends through the form or mold, also extended through the bolt, the purpose of which will presently aippear. The
erent man-' ners but preferably as a hollow screw, as indicated in Fig. 4:, so that the wire 7, passes therethrough and is connected to the outer face by anywell known means, preferably by means of a nut or washer 8, so that the end of the wire will not the bolt as the wire is tightened to draw the sides of the molds together against the interior braces or separators 9. Any form by means of which the wire is connected to this have invented certain new the next form boards;
slide through bolt 6 may be used without departing from the spirit of my invention.
The novel idea of my improved mold rests almost entirely upon thefmeans whereby I hold the frame in position from the inside of thewall or mold. The wires are not removed from the concrete it simply being necessary to disconnect them from their washers and remove the forms. I
Mounted between the boards 1 are the frames or pipes 10, whose lower ends extend into the earth below the first form, and pro- .ject upwardly, providing a means whereby the wires 7, are connected thereto so as to properly hold the forms against the'ends of the braces 9, the wires being tightly secured to the-frames 10, so that the said frames form a central holding means for the molds.
These frames are left within. the wall and assist in forming a reinforced concrete wall.
From the foregoing descrlption, it is evident that I provide a new and novel con-,
lVhatI claim as new and desire to secure Letters Patent is Y 1. In combination with a metal framework to remain in the wall, ofa mold, comprising a seriesjof form boards adapted'to rest one upon the other as the wall is built, means for holding the boards apart, flexible means connected to the framework and passing through to the exterior of the boards, and means mounted in the boards for engaging the exterior ends of said flexible, means and tightening said flexible means, whereby the-formboards are clamped tightly against the, holding means, as set forth.
2. In combination with a metal framework to remain in the wall, of a moldor frame comprising the form boards, a series of cleats connected to the exterior thereof and having their upper ends projecting above the upper and means for con- 5 them to be readily removed afterthe structure has set.
In combination with a metal framework to remain in the wall, of a mold or frame as herein described, consisting of the form boards, braces for holding-the boards apart, cleats carried upon the outer face of the 4 boards and having their edges projecting v/above the upper edge thereof adapted to engage other boards to prevent the spreading thereof, and flexible means passing through 1 the cleats and boards and engaging the framework for holding the boards in close i proximity to the braces and whereby the mold plates are readily disconnected by disengaging said flexible means.
In testimony whereof I affix my signature in presence of two witnesses.
