To all whom it may concern:

Be it known that I, JAMES W. KEENAN, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Molds for Concrete Basement-Walls, of which the following is a specicati'en, reference being had therein to the accompanying drawings.

This :invention relates to a lmock-down mold for concrete basement walls and its object is to provide a mold 'formed of sections which are interchangeable and are adapted to be set in a vertical position and reach from the footing to the top of a wall so that the entire wall may be made Without resetting or changing the mold sections.

A further object of the invention is to provide a construction which is such that the mold may be readily set up to provide for a basement of any desiredfdimensions and which is so constructed that the windowV frames and sills may be set in place and molded into the wall during its formation.

A `further object of the invention is to provide convenient means for alining the mold sections to facilitate the placing of the sameand further to provide lcertain other new and useful features in the construction and arrangement of parts.

To these ends the invention consists inthe matters hereinafter set forth and more particularly pointed out in the appended claims reference being had to the accompanying drawings in whichs.

Figure 1 is a perspective view of a portion u of a mold embodying the invention; Fig. 2

is a perspective view of one of the mold sections detached: Fig. 3 is a sectional view of a mold section for use in forming a corner of the wall; Fig. 4 is an enlarged sectional detail of a portion of a mold set up; Fig. 5 is a perspective detail showing a locking device for the sections; Fig. 6 is a transverse vertical section through the mold showing the same in operative position and a filler plate in place therein; Fig. 7 is a perspective View of a filler plate detached; and F ig. 8 1s a perspective view of an alining bar.

In the construction of concrete walls it has been the common practice to build up a mold of a plurality of horizontally disposed members or to build the wall of sections beginning at the bottom of the wall and lifting the mold upwardly one section at a time as has been filled in becomes set so that the neXt y,

section above may be formed thereon.

Applicant proposes to build his moldV walls of a plurality of narrow sections set on end and of a length equal to the height of the wall so that the entire wall may be built by filling in the mold without the necessity for resetting or shifting theV mold walls and walls of any desired dimensions may be readily made by using a greater or lesser number of sections. Each of these sectlons l comprises a rectangular strip of sheet metal 2 bordered by side angle bars 3 and end angles 4, which are secured to one face of the sheet metal strip at its edges to give strength and rigidity to the strip. These angle bars also serve to hold the sections in position in the mold by being provided with openings near their ends, the side angle bars 3 being each provided with holes 5 equidistant from its ends' and the end angle bars 4 being' rovided with holes 6 which are equidistant rom their ends so that the holes in one section will register with those of the next section regardless of which end of the section is laced at the top of the wall or of Whether t e section is placed withinthe inner or the outer mold Wall.

In setting up the mold footing strips 7 are first placed in position in the bottom of the excavation, said strips being spaced apart according to the thickness of the wall to be constructed, and these strips are providedwith upwardly extending spaced pins 9 adapted to engage the holes 6in the angle bars on the several sections to hold said secs tions in lace at their lower ends. The yseveral sections to form the inner and the outer walls ofthe mold are then set up side by side with the pins 9 engaging theopenings in their lower ends and the sections are then locked together by meansl of keys 10 each having a longitudinal slot 11 toreceive a Wedge 12. The keys are inserted inthe holes andv the wedges then driven into the slots in the keys to draw the contacting flanges of the side angle bars of adjacent sections into close contact and lock them together to form a continuous solid mold Wall. The lower ends of the several mold Sections are alined and held in perfect alinement by thel pins von the footing strips 7 and toaline the upper ends of the several sections and hold them in alinement, flat bars 13 are placed similar to the keys 10 areinserted in the holes in the spacing bars and through the openings in the alining strips and the holes inthe upper ends of the several mold sections. These pins are held in place by means of wedges 18 similar to thewedges 12 and thus the two mold walls are firmly held in spaced relation by the spacing bars and the several sections of each wall are held in perfect alinement by the alining strips. To hold the mold in vertical position before the concrete is lled in, brace rods 19 are provided, said rods engaging openings 20 in the side angle bars 3 of each mold'section, said openings being positioned equidistant from each end of the sections so that they will register with the openings of the adjacent sections regardless of which end is up when they are placed in the mold.

Whenever itis found desirable to place a window frame in the concrete wall, an opening for such a frame may be provided by placing .a suitable number of short mold sections 20 in the outer mold wall at the point where it is desired to have the window and after the mold has been filled up even with the upper ends of these short sections, the usual stone window sill 21 is laid in place and the window frame 22 then set in place upon the sill and against the inner vmold Wall which is formed of full length sections. To form a rounded corner on the concrete wall at each side of the window frame between its outer edge and the outer surface of the wall, a sheet metal forming strip 23 is secured at one edge to the outer edge of the window frame by screws or other suitable means passing through its flanged edge and the opposite edge of the forming strip is secured to the adjacent mold section by providing said strip with an angle bar 24 similar to the angles secured to the mold sections and this angle bar is provided with an opening to register with the opening 5 in said adjacent mold section so that the forming strip may be secured in place by means of one of the keys 10. rlhese forming st-rips are curved or bent in transverse section to form a rounded corner on the concrete wall and may be of any form desired. Window frames and sills may thus be built into the concrete wall at any desired point and are firmly held in place by the concrete of the wall in which the frame and sill are embeddedn messer lf found desirable, an alining bar 30 may be employed to hold the short sections in place at their upper ends, said bar being formed with laterally extending ears 31 formed by severing portions of one flange of the angle bar and turning these portions at right angles to the flange to project inward alongside the flanges of the bar 3 of the sections, said ears being formed with openings to register with like openings in said bars 3 so that the sections may be secured together and the alining bar to the sections, by keys like the keys 10.

ln constructing brick veneer buildings it may be desirable to continue the brick veneering downl upon the outside of the basement wall to below the ground line, and

lit is therefore necessary to provide a seat or ledge upon the concrete wall for this veneering. To provide such a seat, the upper portion of the concrete wall is reduced in width by means of a series of filler plates 25 arranged side by side, each of a width equal to the width ofthe mold sections 1 and each formed from a single piece of sheet metal which is bent at its lower end to form an outwardly extending flange 26 and is similarly bent at its upper end to form a flange 27. The .body of the plate may be strengthened to prevent its being bent by the pressure of the concrete against it, by means of an angle strip 28 secured upon its outer face between the end flanges. After the mold walls have been set in place, the filler plates are placed within the mold with their flanges 26 against the inner face of the outer mold wall and their upper flanges 27 engaged over the upper edge of the wall. The flanges 27 are provided with openings 29 spaced apart to correspond with the openings 6 in the ends of the mold sections and to hold the filler plates firmly in place, the pins 17 are inserted through the spacer bars, the openings in the liner strips and through the openings in these filler plates and the corresponding openings in the mold sections. rlhe filler plate is spaced from the outer mold wall by its flanges just far enough to give the desired off-set in the concrete wall and form a seat or shoulder thereon of a width to accommodate the brick veneering.

By forming the mold walls of narrow sections which are 'of a vlength equal to the height of the concrete wall to be formed, the mold may be quickly and accurately set up and the same sections used to build up molds for concrete basements of various dimensions and as these mold sections are alike upon both sides and ends they may be placed in either the inner or outer wall of the mold with either end up, thus obviating the necessity for using care in placing the sections and facilitating the erection of the mold. By the use of short mold sections and forg strips, the window frames and sills may be set in position and the concrete wall formed around them thus securely and accurately holding them in place.
