To all whom-fit may concern: I Beit known 'that we, PHiLIPPE A. Dns- Leemans and Lome P. DnsLAURmns, citizensv ofl theilnited States, residing at St. Paul, in the county of Ramsey and State of Minneseta, have invented certain new and useful improvements in Means for Constructing Concrete Columns, of which the following is akspecitcation.

. Our invention relatesto improvements in and consists particularly off an improved holding said mold orf casing'i-n position.

To this end our inventionconslsts in the' features of construction and combination hereinafter particularly described and claimed.

In the accompanying drawings forming part of this specification, Figure l is an .ele'

vationof our invention; Fig. 2 is a section on line w-m of Fig. l; Fig. 3 is a section on line yy of Fig.1; Fig. 4 is a detail of a templet frame; Fig. 5 is a similar View with the templet frame open and shown arranged in" connection with the casing; Fig. 6 is a detail of a block used in connection with vthe templetframe; Figs.'7 and S'are views of the interlocking ends of the'templet frame Fig. 9 is a perspective view of a door for the casing; Fig. 10 is an elevation of a'modilied form of our invention for forming square columns; Fig. 11 is'a section onl line e-e of Fig. 10; Fig. 12 isa section on line c-o of Fig. 10; and Fig. 13 is a detail of a templet frame used in connection with the modified form of casing shown in Fig. 10.

In the drawings A represents. a mold or casing made of sheet metal.

In order to make the casing expansible tov mold dill'erent sizes of columns we construct it of two adjustably connected plates 2 and 3, the plate Sbeing connected with the plate 2 by means of boltsmft passing through the main plate 2 and througlone of a series'of openings .i in theextension plate 3. The

.each templet frame is corposed of two curved arms having hinge c nection 8 and adapted to be connected at their free ends by means of a bolt 9 hinged to the end .of one arm 'and adapted to extend through a socketpiece l0 extending outwardly from the end of the other arm, the bolt 9 carryin a nut 1l to bear against theV inner side of t e socket piece 10. The nut 11 may thus be adjusted to tightl `clamp the frame upon the oasingiV In ordy r to decrease the diameter of the templet frames when the casing is adjusted to its smaller diameter We provide a series of blocks 12 each block carrying an outwardly and downwardly bent catch 13 to hook over the templet frame, as indicated in Fig. 1. The templet frame may thus be decreased in size to iit'any size of casing 'by vusing blocks 12 of the proper thickness.-

nAs shown in Fig. l' a metal ring 14 is provided for the base of the column and the casing or mold A is supported upon said ring and is centered by means of arms 15 extending downwardly from the lowermost frame B and interspaced from the'b'ase ring .14- by suitable filling blocks 16.

The casing A mayconsist of a series. 'of sections sultably secured together and connected by bolts 17. Thecasing near its bottoni is provided with an'opening, closed by a suitable sliding door 18 so that the shavings Iand other refuse may be removed before the sameis ill'ed with concrete to form a column, and to allow access to the internal rods of the column.

In the modified construction shown in Figs. l0 to 13 we show our invention adapted for use in thelforming of square columns.y In thisl modification'the casing Aie composed cfa series of plates adjustably connected by bolts 1S) passing through openings 2O in the plates, a series of openings being arranged to allow adjustment ofthe plates. '.lhe plates as shown are bent to form a squarefc'asing and are adapted to be interlocked -by means of angle irons 2l extending outwardly from the free ends of the plates and connected by bolts 22. In this construction the templet frame preferably consists of two right angle shaped. bars 23 adjustably connected together'by bolts 24 extending through openings 25'in the bars, a series of openings being provided te allow adjustment of the bars. Thus filling blocks 12 are not required in the form shown in Figs. 10 to f13., In this modified form we l have shown the lowermost templet frame.

'i0 frames and casing will be removed.

bolted to brackets 26' carried by the-base formingmold.

In use the casing will be set up as shown in the drawings, adjusted to the proper size; and reinforced and held in shape by the tem let frames. The casing will then be fille with the concrete to form the column and when'the same has been allowed to stand an indefinite number of times in the forming of columns. As shown, they may be adj listed to form different sizes of columns.

It will be evident that our invention may be employed for molding a hollow column in lwhich case' the casing A will be turned inside out and the templets arranged to 't within the casing instead of surrounding it.
