To ad whom t may concern."

Be it known that we, ARTHUR FAGER- LUND, a citizen oi Finland, and EMiL- SUNILA, a citizen of the United States, both residents of the city of New York, borugh of Brooklyn, in the county of Kings "and State of New York, have invented a newand Improved Concrete-Mold, of which the following is a full, clear, and exact description.

rlhis invention relates to concrete molds and has for an object the provision oi' an improved construction of mold designed for molding columns and the like in concrete buildings or separately.

Another object, in view is the provision of a mold formed from sheet metal and arranged with means whereby thethickness of the mold may be readily adjusted.

Another object of theinvention is to provide a mold with means for adjusting the depth and means Jfor adjusting the connection between the head and the main part of the mold whereby the same ornamental head may be produced on both large and small columns.

. A further object of the invention is the provision of an improved arrangement of identical braces for holding't'he mold in a vertical position and for adjusting the same accurately.

, A still further object of the invention is the provision oi bracing means or frames for holding the body of the mold in proper position.

. In the accompanying drawings Figure 1 is a rear view of the upper end oftwo molds and certain bracing means embodying the invention.

Fig. 2 is a transverse sectional view through F ig. 1 on line 2 2.

Fig. 3 is an edge view oone of the molds Vshown in Fig. 1.

tures of the invention, the same being taken through Fig. Llapproxirnately on line Fig. 8 is a sectional view through Fig ,-A

on line 8-8.

Fig. 9 is a fragmentary perspective view of a supporting structure embodying' certain features of the invention.

Referring to the accompanying drawings by numerals, 1 indicates a -mold or form for casting concrete columns, said form being held in proper shape by the bracing frame 2: The mold 1 maybe shaped in cross sectlon as shown in Fig. 3, may be shaped square or may be shaped in slightly modilied ways without departing from the spirit of the invention, and continually permitting the frames 2 tol hold the front, back and sides in proper position. As shown in Fig. 2 the back plate 3 is fiat while the front l'ate 4 is curved or rounded and is connected y bolts 5 to the sides 6 and 7, said' sides being iiat. All of the parts are preferably made from sheet metal and, consequently, the frames 2 are necessary to hold the parts in proper shape while the concrete is setting. The side plates 6 'and 7 are provided with a number of apertures for accommodating bolts 5, as shown in Fig. 3, whereby the front plate 4 may be in the position shown in Fig. 2 or the dotted position shown in Fig. 2, as well as in other positions, so as to vary the thickness of thecolumn from -ront to rear.

ln concrete structures, especially in concrete buildings provided with columns, it is customary to provide a comparatively large column on the ground floor and smaller columns on the upper floors, the smallest being on the `top floor. ln order to carry out this l ide-a and to scientifically reduce the amount of weight to be carried, the front plate is moved toward the rear plate 3 on each loor and thereby reduces the thickness oi the column without aieoting the width. ln

order to produce proper shaped corners at the rear, corner members 8 and 9V are provided having langes 1 0 and 11 accommodating bolts which pass through the flanges and through the back plate 3 and the side plates 6 and 7 respectively. The side plates 6 and .7 are cut away at 12 and 13 in order to allow a wrench to be inserted when apply` ingor removing the bolts 14 and 15.

As above mentioned, the frames 2 are provided or preventing any outward movement of the plates when properly adjusted. These frames are made up of bars 16,17, 18 and 19, bar 16 navlng turned over hooks 2O and 21 at the endswhile the bars 17 and 19 have hooks 22 and 23 at one end of the respective bars and apertures 24 and 25, respectively, at the opposite end. A pin extends through. each end of the bar 18 and through one ot the apertures 24 and 25, respectively, for holding the bar in any position, as for instance, that shown in Fig. 2. The hook ends of thebars 17 and 19 overlap bar 16 whereby the various` wedges 26, 27 28 and 29 may be used and caused to press the bars against the side plates andthe back plate continually and hold the same in this position during the casting and setting of the concrete.

' After the column has been properly set and it is desired to remove the form it would be diliicult to take the pins or bolts out of bar 18 and apertures 24 and 25 without loosening the frames 2. By constructing the wedges 26 to 29, inclusive, as shown in Fig. 2, the loosening action may be provided by driving these wedges out, whereupon the frame may be readily removed and aitter- 'Ward the bolts 14 and 15 removed. Ylfhis will allow the lvarious plates oi the mold to be slipped from the column. ,Y

In order to provide a proper spacing and reinforcing member for the frames an angle bar 30 is provided, which may be Sea cured directly to the various bars 16, as

shown in Fig. 2, while a steadying bar 31 is connected by a bolt or otherwise to the upper end of bar 30, as shown in Fig. 1. The bar 31 extends horizontally from one form to the other in order that the upper end oit the various forms may be properly spaced apart and held against side movement. A suitable diagonai brace 32 (Fig. 3) is 4provided for preventing the form from swaying toward the front or toward the back, as hereinafter fully described. ln this way the forms are properly maintained in position for casting during the setting operation while allowing a ready removal after the column has set. lt will be noted that all 'the parts may be applied and removed without injury so that the molds or forms may be used over and over. j

As above stated, the columns 1n a building are of different sizes, the smaller sizes beingarranged at the top and the larger sizes at the bottom. The heads of the columns, however, are preferably the same size throughout, and in order to provide a proper head a sheet metal form 33 is provided, as shown Vin Fig. 5, which is held in a given shape by the

bands

34 and 35 which are readily secured to the various strips of metal making up the head. Suitable reinforcing T bars 36 are also provided, as shown in Fig. 4, for bracing the sheets forming the head. ln order to cause the concrete casting to merge into the main column an apron 87 is provided, formed of a plurality of plates conmedica that each plate is pivotally mounted on one of the bolts 38 and is allowed to move by reason of the slot 40 though subject to be clamped in any adjusted position. .By providing an adjustable apron of this kind for the head 33 the column will properly merge into the cast head and, consequently, will produce a complete column; The head 33 with the apron 37 is removable andordinarily rests against the'upper edge of the plates 3, 4, 6 and 7 and is held against tilting movement by suitable guy members 41 and 42, said guy members being of substantially guy structure, as for instance, a guy wire provided with a turn-buckle 43 whereby an easy adjustment is provided.

1n setting up the molds it is oftentimes more or less diiicult to have the same perfectly vertical, and in order to provide an easy adjustment of the parts for causing the molds to be absolutelyvertical a'diagonal brace is provided which is connected with a rod 44, as shown in Figs. 4, 7 A and 8. rllhe rod 44 is 4preferably somewhat loosely fitted into the end ot the brace 32 and pivotally mounted :f1.t45 to the top frame 2; This top frame carries at the end a .fitting 46 formed substantially U shape as shown in Fig. 7, said fitting being of metal and provided with a slot 47 through which. the rod or bar 44 extends. rl"he rod 44 is provided with a nut 48 which is rigidly secured thereto, and which accommodates the threaded rod 48', said rod extending through slots 48 at each side of the frame 2 as shown in Fig. 7, so that when the rod 48 is held by a wrench or other member engaging the square ends of the rod nut 4S will be moved and consequently the rod or bar 44 will be moved so as to shift the position of frame 2 and consequently the position of the upper end of the entire mold. The frame 2 shown in Fig. 7 and also in Figs. 3 and 4 is made from metal, but as disclosed in Fig. 7A and Fig. 8 the lll-shaped member 46'may be secured 'to a wood 'frame 2, the parts operating as just described. This will allow the adjusting mechanism to be'applied to wood frames now in common use as the U-shaped fitting 4G may be nailed or otherwise rigidly lsecured either to a wood frame or to an extension and a proper adjustment secured in a similar manner to the way the steel or iron trame it adjusted.

lt will be noted that the forms are made from sheet metal, but it is to be understood that other materials, as for instance, wood, may be used without departing from the spirit of the invention. lt is also to be understood' that the diagonal bracing member 32, the rod 44 and associated parts for adjusting the vertical position of the mold may be used with wooden molds, metallic anaemia l' y i from .I l material realise; departing from the Spirit of the e a', number of columns the is connected `to the'vertical reinforcing bars s in anysuitable manner, as shown in Figs. f l and v2,f`said reinforcing bars thereby rein- Laforcing' the rear of the column and at the e" Sametime providing means in connection with 'bar 31l for holding the forms properly a spaced. The-supporting :structure shown :in

`thering or band 73 is caused fto engage the angle iron against the ceiling as shown in Fig. 4 so that 'thenished column willi extend up to and lmerge. intcethe ceiling. t
