MOLD FOR CONCRETE CONSTRUCTION.

To all whom t maycoacera: y

Be it known that I, FRANK M. VoGAN, a citizen of the United 7States', residing at Canton, inthe county of Stark and State of Ohio, have invented a new and useful Mold for Concrete Construction, of which the following is a specification.

My invention relates to improvements in molds for concrete construction to be used for forming concrete structures such as buildings wherein the walls, floors and ceilings are cast in plastic concrete and when hardened produce substantially a monolithic structure. i C

More especially the present invention re- `lates to a mold of this character which is made up of separable units, each of said units being provided with a molding face which may be of any ornamental design.

The object of the invention is to provide knock-down forms or surface molding units, preferably made of sheet metal and adapted to be connected in any appropriate relative position to produce diEerent desired surface e'ects and to accommodate rooms of various sizes and proportions.

A further object is to provide surface molding units which are composed of comparatively heavy material and provided With detachable molding faces which are formed of comparatively light material.

Another object is to provide means whereby various surface molding units lmay `be altered so as to produce various detailed ornamentation of the finished surface, or

.to produce more or less detailed ornamentation, as may be desired.

With these objects in view the inventionl consists in the novel construction and arrangement of parts, hereinafter described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that various changes in the form, proportions, size and minor details of construction may be made within the scope'of the appended claims, without departing from thespirit or sacricing any of the advantages of the invention.

In the drawings:

Figure l is a view principally in perspective and partly in section, illustrating mold units assembled and arranged for the construction of a ceiling with pendant decoration member and pillars, showing the' false Specification of Letters Patent.

Fig. l0.is a fragmentary sectional view showing the means for connecting the appliqu sheets to the mold units.

Similar numerals of reference indicate corresponding parts throughout. the several views of the drawings.

In a preliminary and general way it may be stated thatv my invention contemplates sheet metal mold units embossed with the design'which it is desired to impart to the surface of the concrete Wall, ceiling, pillar, or other structure to be cast, or provided with appliqu plates or sheets embossed with the proper design, the marginal edges of each mold unit being bent outwardly away from said surface to afford means for holdf means for receiving and holdingthe said l. Xoutturned marginal edges of the `mold units.

l lAlthough the present invention has'morel .especial relation to the construction and operation of the `mold units, it is necessary that some form of false work beemployed to support the 4mold units in assembled rela-v A tion and'although any suitable form of false work may be provided for assembling the 'sections the preferred form of false work v is illustrated in the accompanying drawings and'before affurther and more specic description of the mold is given the false work such as is illustrated will be described in a general way. l

Each false Stringer unit comprises a Stringer base 1 whi'ch is preferablymade of weight'and strains to which it' willjoe subv jected as hereinafter more fully disclosed.

'Connected -to the Stringer base 1 is the vertically extending Stringer web 2 preferably formed of two juxtaposed timbers set, up upon one ed e. Extending along the upper free edge o the web 2 isa compound slotY comprising' the shallowen, broader joint bead forming portion 3 and the moldimarj g gin-receiving portion-4 extending from the botto-m of the portion 3 deeper into the web and being narrower than the portion 3 so as to( produce oppositely disposed olf-sets or shoulders'. In'ord'er to 'provide against rapid wear -the slot is preferably provided with va sheetmetal lining 6, the edges 7 of said lining being countersunk into the edge of the web 2'.l

At predetermined equal intervals oiispac-A ving along the. web 2 are transverse mold jolnt4 notches corresponding in cross sec.

web 11 provided alongits upperedge with` a compound slot of the same crosssectional shape and size as the slot in the Stringer web just above described. The partsof the y slot in the joist units illustrated are numbered the, same as the parts ofthe slots of the Stringer units. The joist base is prefer-l ably notl formed inthe same manner .asthe` Stringer base, but is formed by two joist base-strips 12 xedly connected to -the lower side .edges of the webs 11. The joist web at both ends-of the joist unit extends v'slightlyv beyond the ends 'of the joist base. At each end of the joist is also arranged a transverse spline member 13 provided with a rounded wood Qfa sufficient size to 'withstand the .angles tothe web2 and the end ofthe joist unit may then be moved along .upon the base v It will be understood that in setting up -upper edge adapted to ft into the upwardly l' curved grooves in the'blocksvlabove described. The upper edge of each spline' member 13, vit-willv be understood, is above L f ,zofj

the upper surface of the joist basefstrips 12; [t should be stated at this point vthat the two blocks 9 of each pair are spacedfrom" each other just the necessary distance to receive between them the web 11 of the joist unit and the upper edge of the s line member 13 with relation to 'the upper edge of theweb 11 is such thatwhen the upper edge of said web 11 is raised to coincide -with thejupper edge of the web 2 of one of the stringers the'sald spline13 will engage` the grooves in. the 30 blocks 9. The height of the webs 11 is less )than the height of the webs2 so that a joist unit may be arranged with its base on top of the base 1, theweb ll'extendingat right- 1 until the proper relative position with the blocks 9 has been reached, whereupon the joist unitl'may be raised until thesa'idspline 13 engages the grooves in the .blocks 9, and 90 a joist supporting block 14 may then' be arranged between the underside of the base of the joist unit` and' the top side of the base' 1 of the Stringer unit to support -said joist unit and hold it infirm engagement with 95 the Stringer unit. When in this Aposition it will be understood that 'the compound slot of the joist unit registers with vthe 'mold joint notch in the Stringer unit.

false-work in accordance` with my invention a plurality of Stringer lunits will .be placed in paralleland equally spaced arrangement and a plurality of joistunits will then be employed to connect the various Stringer units, said joist units extending transversely with reference to said stringer units. y l

In the construction of ceilings it will usually be found desirable t0 provide sheet metal mold units which, throughout their greater extent, will require supportin order to sustain the great weight of the plastic concrete cast upon them. It will hereinafter more fully appear that theedges of such mold units will be sufficiently supported by the stringers and joists.

In setting up the false-work for the construction of the walls and ceiling of a room a heavy supporting frame must be provided, the cross beams 21 of which are adapted to receive' and support the false Stringer units which extendv transversely with relation to said beams. The beams 21 extendsubstantially to the side walls of the room and at the side walls are the beam supporting and wall framing Vertical units. Said vertical units are substantially the same in constructionas thestringer units.

As an illustration of one 'type of ceiling and permitted to harden.

cordance with my invention attention is called to Fig. 1. Therein it will be noted that 'the fieldl of said ceiling is formed of a plurality of square panels 23, the outer row of panels around the room being promolding and it will be understood that such panels may be formed in such plain fashion or decorated as may be desired. Between the panels extends a portion 24 in high relief which may be termed the frame portion and which not only extends between the various panels, but also externally with .relation to the outer panels. 'A pendant decoration member 27 is shown in the center of the panel 23 and it will be understood that these pendant decorations may be provided at intervals upon the ceiling for the purpose of decoration or in order to accommodate chandeliers or lamp globes.

Referring now to the mold units, it vwill beunderstood that the same arestamped from sheet metal and an inspection yof Fig. 2 will give an understanding o'f the form of said units designed for the molding of the various panels forming the field of the ceiling, such as illustrated in the outer row of panels in Fig. l. Each panel unit of this kind is formed exactly square and is pro-v vided with a joint-bead-forming compound flange 33, illustrated in a number of the iigures of the drawings, and with a marginalholding flange 34. Two opposite edges o-fA said panel mold unit are let into the slots of adjacent stringers and the other two opposite edges are let into the slots of adjacent joist units. If desired the compound flanges 33 fitting into the joint-bead-forming portions 3 of the slots may be left open to form a joint-bead in high relief in the molded surface, or a joint fillet 35 comprising a strip of material may be arranged as illustrated in Fig. l to fill the said .space and prevent the molding of such a joint-bead.

After the ceiling and wall mold units have been properly arranged and connected as'described and illustrated the plastic concrete is poured from above between the wall mold units and on top of the ceiling mold units When the concrete has sufficiently set and hardened the false-work units as well as the mold units may be removed section by section and again used at other places in the same or different combinations.

It will be understood that in carrying out my invention the concrete first applied to the and for lthe purpose of more faithfully reproducing every detail of decoration embossed in the mold units.

As for instance 'ixr the'lield-panel mold units such as illustrated in Fig. 2, it is some times desirable to change the detail decoration, as from the egg and dart pattern to that of some other pattern of molding. In order to provide not only for the convenient and ready change of decoration without requiring the entire mold unit to be changed or replaced, but to provide for the making v of the ornamental portions of the mold units from sufficiently thin material to properly draw under the drop hammers or presses so. as to produce sharp and distinct and even and perfect lines and also for the purpose of 'the ready removal of the deeply stamped decorative portions of the molds from the finished molded surface, I provide appliqu decoration members 38 stamped from comparatively thin material and adapted to be applied to the heavier mold units 39. In Fig. 3 is shown a mold unit from which one of the appliqu molding members has been removed. Said member is shown in Fig. 5 and will be seen to comprise merely a strip of material embossed with the decoration desired and provided with apertures 49 adapted to register with apertures 50 in themold unit to provide for fastening means, such as bolts or rivets to fasten the appliqueJ members to the mold unit. Without the appliqu members such a mold unit would produce a panel such as the plain or undecorated panel illustrated in the upper right hand corner of Fig. 1. With the appliqu members connected to the mold section however the egg and dart decoration illustrated in the other panels will be produced. The pendant decoration member 51 which is illustrated in Fig. 4 is provided around its upper edge with an outwardly disposed annular flange 52 adapted to rest upon the annular shoulder 53, which is provided around the periphery of the aperture 54 in the field mold Aunit shown in Fig. 3, the apertures 55 provided in the flange 52 being arranged to register with the apertures 56 upon the annular shoulder 53 for the purpose of receiving bolts or other means of temporarily attaching said members together. It will be understood that any other suitable ornamentation may be substituted for the pendant member 5l. In removing the mold sections from the finished concrete surface, where the decoration involves deep indentations or high projections it may be desirable to disconnect the appliqu members from the mold sections before removing the mold section itself. Then the mold section may be removed and the appliqu members removed one by one, said members being suiiiciently thin to be bentY and warped to remove them from the decorated surface Without injury thereto.

In Fig. v7 is illustrated the method of.' forming a concrete pillar with the use ofl a.

combination of mold units provided with appliqu members,l said appliqu members being formed of lighter material than the mold sections and embossed withl the designs de- '.sired to be conveyed to the finished concrete structure. The mold used informing the of the pillar.l

pillar illustrated inFig. 7 ,comprises the up.- per'mold units which form' the upper portion Al of the-shaft'and the' capital B and lthe lower mold units which form the lower portion C of the shaft and the base D. The

lower mold units designated bythe numeral 58 each comprise a heavy rectangular sheeto'f metal, the lower'- Vortion of said sheetbeing shaped to con orm substantiall with the design desired to be applied to t e base u decoration'sheets being provided withs1de flanges 63 and upper and lower horizontall anges 64 andA 65 respectively, said ,appliqu sheet having embossed thereon the design desired to be applied to the pillar, the appliqu decoration sheets illustrated in the accompanying drawings being provided with a series of vertical ribs 66, adapted to` imprint corresponding yimpressions in the face ofthe pillar and with any suitable design which may be desired upon the base.

, Each of the upper mold units is formed substantially the same as the lower mold units,

each upper unit being provided along its vertical edges with outstanding) angularA {ianges 67, said upper mold units ing ,also provided with upper and lower horizontal anges, the appliqu decoration plates adapted to be connected to said upper mold units being formed in substantially the same manvner as the Aappliqu decoration plates attached to the lower mold units. When it is desired-to build up amold for forming a pillar or similar structure the appliqu deco-v ration sheets. are placed upon the inner faces of the mold units and bolts or their equivalents 68 are tures in the anges 5,9 and 63, thus holding A. v. i

tures and bolts located through the apertures assed through suitable apereach tier of mold units and appliqu decoration sheets rigidly together. Theupp'er and lower tiers of mold units are connected to each other by means of the horizontal ianges upon thejbottom of the upper moldunits andthe top of the lower'mold units respectively, bolts'being passed through suitable apertures formed 1n these flanges. The

lvertical flanges of the mold units and ap'- pliqu decoration sheets are each notched at intervalsas \at 69 to receive the tie bandsv Each of said sheets is pro-- drawings. f
