Application filed August 29, 1912. Serial No. 717,740.

To all whom it may concern Be it known that 1, LE ROY K. VAN HORN, a citizen of the United States, residing at Youngstown, in the county of Mahoning and State of Ohio, have invented certain new and useful Improvements in Molds for Making Concrete Structures, of which the following is a specification.

My invention relates to molds for cement or concrete walls, and particularly to detachalole, adjustable molds.

The object of this invention is to provide means of this character for forming cement walls, beams, columns, piers, sea walls, etc., of uniform or varying thickness, or any regular geometric shape, and having plane, offset, or beaded surfaces.

Another object is to provide a structure of this kind for forming ceilings, girders and floors.

An important object is to provide a structure of this character which is composed of plane sections, adjustable angle and corner sections, and curved sections cooperating with fillers which are all easily detachable from the molded wall.

Another important object is to provide sections of varying lengths cotiperating with adjustable corner sections, in order that the molds may be adjustable to a very small degreeg1 for forming walls of any length desire A further object is to provide eflicient and simple means for spacing and securing the two walls of the molda Still another object is to provide means for quickly and easily attaching together the different plates which form the walls of the mold.

With these and other obiects in view my invention consist. in the novel arrangement and combination of parts as more fully set forth in the following description and claims.

Referring to the drawings forming a part of this SQGClfiRLLLlOH and in which like numerals are used to designate corresponding parts throughout the several views: Figure 1 is a perspective view of my mold for forming a plane, straight wall, Fig. 2 is a perspective view of an angle plate, Fig. 3 is a horizontal section of an angle mold, Fig. 4 is a perspective view of a filler used in constructing an angle, Fig. 5 is a perspective view of a box or corner filler used in constructing ceilings, Fig. 6 is an end view of the mold as arranged for forming a wall of uniform thickness, Fig. 7 is an end view of the mold as arranged for forming a wall tapering toward the top, Fig. 7 is a detail view of a tie-rod, Fig. 8 is a fragmentary perspective view of a modified form of plate, Fig. 9 is a perspective view of a plane and angular mold formed of this modified form of plate, and a section of wall molded thereby, Fig. 10 is a perspective view of various plates arranged to form a wall, a ceiling and girder in one operation, Figs. 11, 12 and 13 are perspective views of securing bars for holding the plates in ceiling construction, Fig. 14 is a perspective view of plates arranged to form a wall, cornice and pitched roof in one operation, Fig. 15 is a perspective view of plates arranged to form a girder, Fig. 16 is a horizontal section through plane and curved plates arranged to form a column projecting from a wall, Fig. 17 is a perspective view of two of the curved plates provided with ofi'set portions for receiving secondary molds for ornamentation, Fig. 18 is a detail section through the union of two such plates, Fig. 19 is a perspective view of a fragment of a wall mold provided with reinforcing supports, Fig. 20 is a perspective view of a clamp for holding the hooks and staples of contiguous plates from displacement, and Fig. 21 is a sectional view of a wall showing means for removing he tubes.

Referring more particularly to the drawings, the numeral 1 designates a fiat plate preferably of iron or steel, and of any desired size, except that it should be a multiple of any desired unit. These plates are provided along one side and one edge with angular hooks 2, and along the other side and edge with rectangular sockets 3. The hooks and sockets on adjacent plates are to co operate with each other as shown. If de sired, these hooks and sockets, after being placed in engagement, may be locked together by means of the locking member 4, as shown in Fig. 21. The plates 1 are also provided with openings 5, to receive tie-rods 6 which pass through the tubular spacing elements 7 disposed between the outer and inner plates of the mold, and abutting a ainst the inner opposing faces of the same. hese tie-rods comprise a head 8, formed tubular for the reception of a bar or the like for removing the rod from the wall when molded, and an extended body portion 9 provided by their use, the length of a wall may be varied to as small a degree as one inch. The corner or angle sections are applied to the outside and inside of the outer and inner walls of the straight mold as shown, and are merely plates preferably bent to any desired fixed angle. The corner sections 12 have openings 13 in their two angular sides for the reception of the hooks 2 on the edges of the plates 1 and are also provided with openings 14 for the reception of the tie-rods 6, and a series of openings 15 for a purpose to be described. In order that these corner sections will mold a wall having a smooth surface, I provide fillers 16 contacting with the inside and outside of the outer and inner angle plates, respectively, as shown clearly in Fig. 3. These fillers are composed of a series of filler plates, as shown in detail in Fig. 4. The filler comprises an angular plate 17, and a series of plates 18 and 19. The plates 18 and 19 may be of any desired width, but it is preferable to form all plates the multiple of a certain unit for purposes of ad ustment.

The purpose in having the fillers in sections is to enable a corner to be properly filled so that the Walls of the mold will be flush, regardless of whether a short angular filler plate, or a more extended filler is required.

In order to secure the filler plates to the angle or corner plates, I provide them with a series of openings 20 adapted to register with the openings 15 in the corner or angle plates, and adapted to receive clamping bolts 21. It will be noted that one of the openings 20 is disposed at the edge of each filler plate, so that the wide fiat heads 22 of 'the bolts will overlap the union of each contiguous plate, and thus hold them in place. The filler plates are further provided with apertures 23 for receiving the tie-rods for holding the forms to ether.

In Figs. 8 and 9 have shown the same general construction of mold, except that the plates, angles and fillers are provided with effect portions 24. These plates are adapted to'form a stepped wall. By securing molding 25 of any desired design within these ofiset portions 24, it is possible to form a wall having ornamental beading or cally in the Wall mold, and horizontally in molding upon its surface, as shown at 26. It will be understood that the tie openings will have to extend through the molding.

In Fig. 10 I have shown an arrangement of plates, angles. and fillers for forming walls, a ceiling, and a girder in one operation. 2'? indicates awall mold, 28 the ceiling mold, and 29 a girder mold. The plates 1, angles 12 and fillers 16 are arranged vertithe ceiling and girder mold 28, as shown.

In order to form the inner corners of the ceiling, I provide corner boxes 30 illustrated in detail in Fig. 5, which are bolted in place by means of securing braces 31, 32 and 33. These securing braces are provided with bolt receiving apertures 34, and tie receiving openings 35. Of course,iin this instance it will be necessary to support this mold structure, For this purpose I employ arrangement of planks 36, and upright posts or supports 37.

In Figs. 14 and 15 I have shown my molds adapted for girder construction, to be used in connection with a wall or ceiling, or separately. In this instance itwill be noticed that scafiolding comprising horizontal planks 38 and vertical posts 39 is required to maintain the mold in its elevated position. These girder moldscomprise plane plates or plates either angular or plane. provided with offsets 40 secured in end to end relation, spaced apart by the tubes 7 and clamped by means of the tierods 6. Within the oifsets 40 moldings 41 of any desired shape may be bolted as at 42 for ornamental effect. In order to sup-port the angular plates a brace 43 may be pro vided having therein an aperture 44 for the reception of a tie-rod 6.

In Figs. 16 to 18, I have illustrated my mold structure adapted to mold a column either connected with or separate from a wall. This structure comprises curved plates 45 .having straight portions 46 extending therefrom for connection with the plane plates 1. The portions 46 are'of the same construction ,as each leg of the angle plates, and are provided with openings 47 for the reception of bolts '48, having flattened wide heads 49, by means of which the filler plates 16 are secured. The curved plates 45 are also provided with hooks and staples ,of the same as on the plane plates, lVhen it is desired to bring two of the curved plates closely together, I provide a bar 50 between them, which may be of any desired thickness. A bolt passes through the portion 46 of the plates and the bar 50, thus holding them securely together. In order to prevent accidental turning of this bolt, a rivet or pin 52 is inserted within an opening through the bar 50 and the bolt 51 as shown. These curved plates 45 may be formed with offsets 53 within which mold- 130 1,1eo,ece

ing 54 may be secured by means of bolts 55, for forming ornamental bases for colmuns.

In very heavy work it is sometimes deseirable to strengthen the walls of the mold. With this end in view, I provide a reinforcing means illustrated in Fig. 19. This re inforcement consists of a series of crosses or spiders 56 disposed upon each of the tierods 6, with the extremities of their arms abutting against each other as shown at 57. Each cross or spider is provided with an opening 58 at the junction of its arms for recei ing the tie-rod.

After the cement has been poured into the molds, and set or hardened, the wedges are removed from the tie-rods, the tie-rods are withdrawn, and the plates are removed. It will be noted that the spacing tubes 7 will then remain in the wall. In order to remove these tubes I provide a device illustrated in Fi 21, comprising a cylindrical portion 59 ot the same diameter of the tube, and having a reduced end 60 which is adapted to be inserted within the tube. It will be readily seen that the blow upon this device will cause the shoulder 61 to force the tube out of the wall.
