CONCRETE-MOLD.

Specification of Letters Patent.

Patented Jan. 26, 1915.

' Application filed May 4, 1914. Serial No. 836,098.

To all whom it may concern Be it known that I, WILLIAM H. TUOHY, a citizen of the United States, and a resident of Eagle, in the county of Waukesha and State of Wisconsin, have invented certain new and useful Improvements in Concrete-Molds; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in concrete molds, and more particularly to concrete molds adapted to be used in the construction of foundations and Walls of the so-called double wall construction wherein the wall comprises a plurality of united sections constructed by the repeated use of my device. I

The features of my invention are directed toward the construction of a mold that is universal or flexible in its use and is adapted to afford greater strength and rigidity in concrete construction by permitting a solid thickness of Wall to be formed at the corners or intersections of wall sections and adjacent to openings in the wall, and by the provision of a simple attachment to render the mold suitable for the building of a continuous wall'of the ordinary double wall construction.

The general features of a concrete mold embodying my invention are set forth in a prior application filed by me on the 27th day of December, 1912, and bearing Serial No. 808,918.

My invention therefore consists in the matters hereinafter set forth and more particularly pointed out in the appended claims and illustrated in the accompanying drawings. in which Figure 1 is a plan View of a form of mold constituting my invention; Fig. 2 is a View in vertical section, taken on line 22 of Fig. 1; Fig. 3 is a view in side elevation of the said mold, with portions broken away; Fig. 5 is a fragmentary view, taken on line 3 --3 of Fig. 1; Fig. 4 is a view in side elevation of the block adapted to be attached to the mold when used in the construction of continuous walls; Fig. 5 is a fragmentary plan view, showing the method of constructing a continuous wall; Fig. 6 is a fragmentary plan view, showing the manner of forming a solid corner; Fig. 7

is a sectional View, taken on line 77 of Fig. 6; Fig. 8 is a sectional View, taken on line 8 8 of Fig. 5, showing the block attached to the mold in position for constructing a continuous wall; and Fig. 9 is a sectional view, showing a modified construction of my device.

Referring to the drawings showing a preferred embodiment of my invention, the concrete mold illustrated comprises, in general, two pairs of mold boards 10, 11 and 12, 13. The pairs of mold boards are separated from each other by a space, and each pair comprises two upright mold boards arranged to be normally maintained in parallel relation and spaced apart to form a space therebetween adapted to receive the concrete for the construction of each of the sections constituting the double wall. The mold boards are preferably constructed of sheet metal and are supported in upright position by means of transversely extending frame member-s 1 1, 1 1, provided with downwardly extending arms to which said boards are secured. The arms supporting one mold board of each pair are mounted in fixed relation to the frame members and the arms supporting the other mold board of each pair are pivotally mounted upon the frame members to permit a limited movement of the bar supported thereby for the purpose of attaching the mold board to and releasing the same from the already completed portions of the wall. A manually operated means is further provided in connection with each frame member for the purpose of simultaneously controlling the movement of the pivoted arms and the mold board secured thereto.

Referring now more in detail to the construction of my device, the mold boards 10, 11, 12 and 18 are arranged with their upper and lower margins in parallel relation. The spaces between the boards 10 and 11, or 12 and 13, of each pair, are preferably equal, and the distance between the inner boards 11 and 12 corresponds with the desired width of the space between the parts of the double wall to be formed by the use of the device. The outer mold boards 10 and 13 project, at one end of the mold, a considerable distance beyond the ends of the inner mold boards 11 and 12. The space between the ends of the inner mold boards, at the same end of the mold and at the opposite end thereof, is closed by means of transversely extended members 12, 12 preferably attached to or formed on the mold board 11, and extending to and overlapping the adjacent end of the mold board 12. The transverse members may have the form of removable or detachable gate members, such as are shown in my prior application, but the form thereof illustrated is preferred for use in molds in which the two pairs of mold boards are not adjustable with respect to their distance apart. The outer mold boards project beyond the inner mold boards a distance preferably about equal to the distance between said outer mold boards, so that there is formed at one end of the mold a rectangular space, which is separated fromthespace between said inner boards by the transverse member 12 The upper margins of the mold boards, by preference, lie in substantially the same horizontal plane. The lower margins of the outer mold members 10 and 13, however, project some distance below the lower margins of the inner mold boards 11 and 12, as shown in Fig. 3. vThe frame members. 14:, 1d extend transversely of the said mold boards and are spaced a suitable distance for properly supporting the boards and for operating the mold, one of said frame members being preferably adjacent to the transverse member 12'" at the shortened ends of the inner mold boards 11 and 12. Each frame member comprises a rectangular structure consisting of pairs of horizontal bars 15, 16, arranged in parallel relation, one above the other, and rigidly connected at their ends by means of vertical connecting members 17 the said connecting members extending between each pair of horizontal bars 15 and 16, and act to hold the said bars at a distance apart to form the space between them. A plurality of rivets 18 extend through the ends of the bars, thus completing the rigid structure of the frames 14:, 14:.

Each of the frame members 1 1, 1 1 comprises a series of vertical arms 19, 20, 21 and 22, said arms extending downwardly and supporting at their lower extremities the several mold boards, there being provided suitable means for securing saidarms to the outer faces of the mold boards. Two of these arms 19 and 20 are secured in fixed relation to the frame and extend between the upper and lower horizontal bar members 15 and 1 6, the same being rigidly held in position by means of bolts 23. The arms 21 and 22 are secured to the frame members in a manner to permit them to. be oscillated through a limited distance,the same being pivoted to the lower horizontal bar member 16 by means of bolts 21. The arm 21 projects a distance above the upper bar mem ber 15, whereas the arm 22 terminates between said upper horizontal bar members.

For the purpose of oscillating the boards 10 and 11, respectively, for the purpose stated, I employ the following members: Rigidly fixed to the frame member 1 1 is an arm 25' which projects above the horizontal bar members in vertical position. Between 22 through the medium of the connecting link 27.

The lower ends of the arms 21 and 19, to which are attached the inner mold boards 11 and 12 project below the margins of said inner mold boards and terminate in the plane of the lower margins of the outer mold members 10 and 13. These end portions are bent inwardly in vertical alinement, with the inner surface of said boards 11 and 12, and are extended below the lower edges of said, boards-to provide, in efiect, a plurality of clamping lugs 19' and 21, the purpose of which will be apparent as I proceed with the description of the operation of my device.

One of the outer mold boards, shown herein as the board 13, is provided at its lower margin with a rectangular recess 13 formed by'rabbetinga portion of the board, at its lower margin and at the end thereof extending below the inner mold boards. The recess extends inwardly from the outer extremity of the board 13 a distance equal to the distance between the outer boards 10 and 13, that is, to. a point oppositethe transverse portion 12 of the inner mold board 11. The width of the recess 13 is equal to the distance which said outer board 13 projects below the inner mold'boards.

The operation of constructing the walls of the so-called double wall construction is, as before suggested, accomplished by the repeated use of my device and in the following manner: In Figs. 6 and 7 is shown a portion of a wall 30, already completed, with the mold secured thereto in position to receive the concrete for the formation of a section of the wall to be superimposed upon said completed portion, and also in position to form the junction of two intersecting sections of the wall meeting at right angles. To secure the mold in position the turn-buckle 26 is manipulated so that the movable mold boards 10 and 12 are swung in a direction away from the stationary moldmembers 11 and 13, respectively. By this operation the space between the pairs of mold boards is increased sufficiently to allow the upper portion of the completed portion of the wall 30 to pass between the boards. The device is placed in position with the lower margins of the outer mold boards slightly overlapping the outer surface of each wall portion and the clamping members 19 and 21 at the lower extremities of the arms 19 and 21, respectively, also overlapping the upper margins of the inner surface of the-wall. By again manipulating the turn-buckle, the movable mold boards are carried inward toward the stationary mold boards, thereby acting to clamp the mold boards to the walls in position to be filled with concrete in the usual manner. The purpose of the clamping lugs willbe now apparent, namely, to provide means for clamping both pairs of mold boards to both walls and at the same time provide that the lower margins of the inner boards 11, 12 shall terminate at the upper margins of the walls, so as not to interfere with the reinforcing rods or members which may be placed in the walls in a manner to extend across the space separating the said walls. Although the mold may be used to form a straight or continuous wall, the form herein shown is more particularly designed for the formation of corners and door 7 and window openings, whereby a solid wall may be produced at said corners and at the sides of such openings. As shown in Figs. 6 and 7, the mold is clamped to the wall and in position for forming a solid corner, as above suggested. In this position the ends of the outer mold boards 10 and 13 project slightly beyond the end of the wall and between said ends is inserted a gate member 31. This gate member may be ofany suitable form, although a piece of board of suitable length and thickness and having a widthequal to the distance between the outer boards is adequate. This member is held in position by the clamping action of the outer mold boards and forms an end closure for the mold. In this position of the mold the recess l3 (Fig. 7) receives the intersecting. portion of the wall, thus permitting the end of the outer mold board 13 to extend over the said intersecting portion without interfering .with the proper positioning of the mold board in horizontal relation to the wall. The mold is now ready to receive the concrete, which is placed between the inner and outer mold boards and within the space beyond the ends of the inner mold boards formed by the outer moldcboards and the member 31. The transverse wall portion 12 thus acts to form an end wall for the space between the inner mold boards so that the corner formed by the intersecting sections of the wallf30 may be of solid construction by the omission of the space which is ordinarily formed throughout the straight portions of the wall. hen the concrete is sufficiently hardened, the mold may be released by manipulating the turnbuckle in the manner indicated and the mold again secured to the wall in position .to form the next section which 1n th1s 1nof a width substantially equal to the width of the space separating the walls. The length of the block is substantially equal to the distance from the transverse member 12 of the inner mold member 11 to the extremities of the outer mold members 10 and 13. The upper surface of the block is provided with an inclined or sloping surface 33, extending substantially throughout its length, as shownin Fig; 4. The rear portion of said block is provided with an upwardly extending arm 34 rigidly attached to the rear surface of the block, the same being. inclined slightly rearward (Figs. 4: and 5) and provided at its upper end with a hooked portion 35. Upon the lower surface of the block is provided a downwardly integral with the block, and the end surfaces of which are flush with the side faces of the block. As shown in Figs. 5 and 8 of the drawings, the block is attached to the mold by means of the arm 34, which. is adaptedto engage the adjacent frame member 14 by means of the hooked extremity 35 of the arm, which enters downwardly into the space between the lower horizontal bar members 16,16 of said frame. In this position the block abuts at its rear surface against. the transversemember 12 and extends therefrom in a direction toward the end of the -mold, its lateral surfaces being parallel to the outer mold boards 10 and 13.

When attached to the mold the lower surface ofthe block lies in the plane of the lower margins of the inner mold boards, and the projection 36 extends downwardly below the upper margins of the walls 30, with its side faces in contact with the inner faces of .said walls, into the space separating said walls. It'is obvious that the said block serves as an extension of the inner mold boards, so that, when the same is in use, the entire length of the mold may be utilized in the construction of the straight parts of the double wall. The projection 86 before extendingprojection 36, that may be made Width, and a transverse member extending between the ends of said inner mold boards, at the same end of the mold.
