MOLD-FORM STRUCTURE.

Application filed August 2, 1927. Serial No. 210,199.

This invention relates to forms or molds by means of which concrete or other plastic material is shaped to form walls and other similar structures, and constitutesan improvement over the type of construction illustrated in my prior United States Letters Patent, No. 1,574,636.

Briefly stated, the present invention provides as an important feature, a corner mold form characterized by the employment of angularly disposed converging articulated side wall sect-ions terminatingat either side of 'the corner angle extremity, these sections being completed by an angle member presenting a vertically extendingiiller of approximate V-shape in cross section forming the corner angle of the mold and constituting a continuation of the adjacent side sections. Bracing means are employed to support and maintain the filler in cooperative relation to the side sections.

As an additional feature, the. invention provides means for alining and joiningv abutting or superposed sections of the mold, one form of which provides means for bracing that section of the mold to which it is attached.

Other objects and advantages will be apparent during the course of the following description.

In the drawings accompanying and forming part hereof and in which a preferable embodiment of the invention is illustrated Fig. l illustrates a. corner mold structure of the present invention with upper and low er superposed corner sections shown separated to disclose the coopera-tive arrangement and interior features.

Fig. 2 is a top plan view of such a mold used in connection with adjacent ends of a building under construction and illustrating the manner of bracing the corner angle members.

Fig. 3 is a vertical section on an enlarged scale taken on the line 3*?) of Fig. 2.

Fig. 4 is al horizontal section on an enlarg ed scale through one of the corner angle members illustrating the coaction of its filler with the adjacent side wall sections of the mold.

Figs. 5 and 6 illustrate different forms of anchoring abutments for the lower ends of turn-buckle braces.

The illustrated articulated mold is of the type illustrated in my prior patent above referred to, the articulated sections comprising parallel form boards 2 arranged in horizontal courses based upon a suitable support such as the foundation l and held in alinement, and against disalinement through pouring, by tie wires 3 in the form of elongated loops extending between adjacent courses at appropriate points with their ends projecting beyond the outer faces of the form boards 2 as at t, and locked in position by a series of vertical locking rods 5, the projecting ends i-of the tie Wires being, of course, in vertical alinement. So far as the purposes of the present invention areconcerned, the particulalform of tie wire is immaterial.

In a corner mold with which the present invention is more particularly concerned, vthe articulated sidewall sections of the mold are disposed in converging angular relation to provide the corner mold structure. The inside mold boardv members of this structure, which as seen in Fig. l, are braced adjacent their meeting angle by tie Wires and locking rods, have their complement-al side memers brought together so ,as to abut, as at 6 and 7, this junction of the sections providing the inside corner of the mold. It is not necessary to provide a nished edge at this point, but at the outer side of the mold, a finished corner angle is highly desirable. In accordance with the present invention, the outer converging side walls of the mold terminate at opposite sides of the outer corner extremity of the mold structure and a sep arate filler' is provided for this portion of the mold. One form which this ller may talre, provides a unitary angle member projecting outwardly from the corner of the mold with divergent

angular sides

8 and 9 braced by triangular cleats 10 and having connected appropriately to their inner edge, a vertically extending V-shaped filler 11 alining with the converging outer side wall sections of the mold to form a continuation thereof and the outer corner angle of the mold. The base of this angle member is fixed in proper position in the mold structure by appropriate means. In the drawings, in the lower section of the mold. in which the base courses rest up'on the foundation l, blocks 12 at the outer sides of the

angle boards

8 and 9 of this member are appropriately anchored to the base or toundation 1 in positions deiining the proper posit-ion for the base of the angle member' which may be secured to these blocks through nails or screws inserted through these angle members.

lVhere in pouring a wall corner, it is desired to pour an additional section before a lower section has been set, a second mold section, as shown in Fig. 1 of the drawings, is superposed over the base section. The side wall sections ot' these two superposed units will be alined through the employment of longer locking rods 5 and in order to secure the angle members 8-9 of the upper section to and in alinement with the lower angle members, joint plates ot novel construction are provided. As shown in Fig. 1 at the upper portion of the .lower section ot the mold, the top edges ot the angular sides 8-9 of the angle members are embraced by substantially lJ-shaped plates 13 bolted through the sides thereof and provided with upstanding pins or dowels 14:. n The base of the superposed angle members 8-9 will be embraced at alined points by similar U- shaped plates 15 bolted thereto and having sockets 16 formed therein to receive the dowels 14 ot the section next below. The joint plates 13, being positioned upon the divergent sides oi the angle members will unite these superposed members in proper alinement, the adjacent side mold sections being similarly alined through the rods 5.

The upper li shaped joint plates 1.3 tor embracing the upper edges o1 the

divergent sides

8 and 9 ot the angle members ot' the mold form sectionV are formed, as best seen in Figs. 2 and 3, with biiurcated offsets 17 forming ears between which eyes 18 are journalled. These eyes serve as pivot links to which the upper biturcated ends ot turnbuclrle brace rods 19 are pivotally connected. These brace rods extend from the outside of the divergent sides 8-9 ot the angle members diagonally downward in opposite directions, their lower ends being anchored to a suitable abutment, which as is shown in Figs. 5 and 6 and in Fig. 1, may be formed by the head ot a bolt or nail 2O extending in or through a tube 2l spacing the lower courses of the inner and outer wall sections ot the mold, the lower section ot the turn-buckle being 'formed as an eye 22 through which the bolt or nail anchor 20 extends.

In the lower halt uji-Fig. 1 ot the drawings, a modified form of a bracing member is shown, this form constituting diagonal brace bars or boards 23 nailed to the outer edges ot the divergent

side angle members

8 and 9 and similarly anchored at their bases to blocks 24 which in turn are anchored to the base support 1. While this form may be used on the base section, the turn buckle negaron brace previously described is of a more permanent nature and is equally a; iicable to the lower course of the mold structure.

rl`he angle members forming the corner angle of the mold, as described, therefore constitutes a movable mold corner element, which may be moved from ins'tallat' n to '.istallation and used over and over again. The corner and edge molding surface provided by its tl-shaped iiller piece will prosent an unbroken line or sui-'tace throughout its height, and a smooth edge finish tor the corner can be secured.

Vlien a corner is first poured and the side walls are nent to be extended, it is desirable to provide the poured side walls with some shoulder or abutment to which the next section poured may be joined. l have secured this result and improved the molding operation by providing end closures for the side sections of the corner mold form, these mold corners being in the form of iiller mold boards 25 sized and shaped to close the ends oli the mold sections and provided on their inner sides with groove-forming ribs QG, the outer edges of the filler beingiboth braced and fixed in position by veV ical cleats 27. The end closure described will form with its rib 26, a. groove in the poured section ot the mold which when set will provide shoulders against which the concrete in the next poured section will abut and set. llhile l have herein described a specific embodiment of the invention, it will be understood that various modifications and adaptations thereot will be permissible within the spirit ot the invention and the scope of the appended claims.
