Specification of Letters Patent.

Patented June 24, 1919.

To all whom it may concern:

Be it known that I, ALBERT J. DESLAUR- IERS, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Adjustable Capital-Molds, of which the following is a specification.

My invention relates to improvements in adjustable molds for COlHHID CZLPS adapted foruse in connection with sheet metal column molds, its object being to provide a column cap so constructed and adjustably connected as to be expansible or contractible.

to mold different diameters of column tops and to cooperate with a column mold of certain size.

In the accompanying drawings- Figure 1 is a side elevation of my improved column mold partially broken away.

Fig. 2 is a top view of the same partly broken away. 7

Fig. 3 is a diagrammatic view illustrating the expansible character of the mold.

Fig. 4 is a plan view of one of the mold sections.

Fig. 5 is a plan view of a member of the cooperating mold section in the fiat, ready for bending to final form.

Fig. 6 is a detail view of part of the rim member for the column mold.

Fig. 7 is a detail view of the connecting union for the rim member.

Fig. 8 is a vertical section through the rim portion of the column mold showing supporting means therefor.

Fig. 9 is a similar view illustrating cooperating supporting means for the rim portion of the column mold wherein the column mold members are so adjusted as to render the use of the ordinary supporting means impossible, and

Figs. 10 and 11 are detail views of a portion of the supporting means in Fig. 9.

As shown in the drawings the improved mold comprises three sections, namely, a top rim or collar 2 having at the bottom a short depending flange 3 bent inwardly and downwardly in frusto-conical shape; an intermediate supporting section or constant section 4, also of frusto-conical shape, which is held outside the flange 3 and extends downwardly and inwardly therefrom, and a bottom flaring section 5, which telescopes over and is adjustably secured to the supporting section 4 by means of bolts. The sections s and 5 are each formed with bolt holes at suitable vertical distances apart whereby the section 5 can be securedto the section at at different heights.

The sections 5 are each made up of anumber of segmental parts which are secured together laterally by means of lap joints in such way as to permit them to be slid laterally upon each other, whereby to contract or expand the diameter of the mold section, and to be secured in such ad usted positions.

When it is desired to use the mold for a capital of larger diameter, the segments comprising the bottom flare section are moved up upon the supporting section 4, which serves as an expander to force the segments apart and increase the diameter of the mold. Similarly to reduce the diameter of the mold it is only necessary to move the section down and push the segments together.

In Fig. 3 a number of different positions of the bottom flare section have been illustrated, showing that as the segments of the flare section are moved upwardly upon the supporting section, they will move apart to form a wider column. For instance, when the flare section is at its lowest position it will stand in the position marked A. WVhen it is slid upwardly a little it will assume theposition indicated by B, and similarly as it is slid up it will take successively the positions C and D, all the time moving out to increase the diameter of the capital, while the rim or collar at the top will remain constant.

To further accommodate the mold to the varying sizes of capitals or column tops sections 4 and sections 2 may be relatively adj usted to overlap to a greater or less extent as desired. This is accomplished by certain novel features of construction in section 2, wherein the circumferential variations are effected through a row of interspaced bolt holes 14, in the vertical wall ends of the segments (Fig. 6) composing the section. Certain of the holes 15 in the flange 3 are so positioned as to register with a certain circumferential row of the holes 16 in section 4, to accommodate a certain diameter to which section 2 is capable of being adjusted.

Thus the section 2 may be expanded or contracted by bolt adjustment, Fig. 9 of the drawings showing it contracted to its smallest diameter wherein it is slid down on the inner face of section 4 and is shown secured in the lowermost row of the holes 16. Thus the diameter of the extreme top of the column adjacent to the ceiling may be materially varied to accommodate variations in stresses due to varying floor slab spans, withoutphanging the column diameter. Obviously, the large range of adjustability for changing its diameter in section 2, would either requirethe use of very short segments which is undesirable) or provide means for changing the curvature of long segments for the purpose of causing the holes 15 and 16 to register. To this end the segments of section 2, have clearance cuts 17, midway of their length, above and below its vertical wall, so that the segment may be slightly bent to accommodate the requirements.

A binding plate 18 having loose fitting bolt connection in the horizontal flange serves to stiffen and hold the segments in adjusted position.

I thus secure a large range of adjustability of the capital top without being forced at the same time to adjust the size of the cooperating column mold (not shown).

In Fig. 8 is shown the supporting means I usually use for the rim portion 2. This includes a block 7 adapted to be secured to the ceiling supporting frame work 8 to form a support for the rim 2 of the mold and an apron 9 supported by the ceiling frame work adapted to overlap the rim 2 and close any space between the rim and surrounding ceiling frame work.

Where in the adjustment of the mold the section 4: is pushed up beyond the flange 3 as shown in Fig. 9, it prevents the rim 2 from resting upon the block 7. To use in this case I provide abutlnents 10 adapted to be secured underneath the upper edge of the section 4- by means of bolts 11. passing through the rim 2, a filling block 12 preferably being positioned between the upwardly projecting end of the plate 4: and rim 2 for support. The abutment 10 then rests upon a block 18 carried by the ceiling supporting frame work in the same manner as the block 7.

I claim:

1. A column capital mold comprising an expansible top rim formed with a downwardly projecting flange, an intermediate section adjustably overlapping said flange, and an expansible, inwardly flaring, circular section adjustably overlapping said intermediate section, and supporting abutments secured underneath the upper edge of said intermediate section and constituting a rim therefor for the purpose set forth.

2. A column capital mold, comprising a frusto-conical section, having at its top a plurality of circular rows of bolt holes concentrically arranged at its upper edge and a row of bolt holes along its lower edge, an adjustable eXpansible section having a circular row of holes, and adapted to be circumferentially adjusted to bring its circular row of holes into register with any one of said plurality of rows of holes, -and a circular upwardly and outwardly flaring section, circumferentially adjustable, and having a plurality of circular rows of holes concentrically arranged along its flaring edge whereby, by means of its circumferential adj ustment any one of said rows of holes in its flaring edge may be brought into register with the holes in the lower edge of said frusto-conic section for the purpose set forth.

8. A. column capital mold, comprising a frusto-conical section, an eXpa-nsible upper section, capable of adjustment to several varying diameters, cooperating connecting means on said expansible section and said conical section whereby said expansible section may be connected to said conical section when adjusted to any one of said several diameters, and an outwardly flaring circular section circumferentially adjustable to vary its diameter, said flare telescoping over the lower edge of said conic section, and cooperating connecting means on said conic and flaring sections whereby, when. said flaring section is adjusted to any arbitrarily selected diameter of which it is capable said sections may be joined together.

In testimony whereof I afliX my signature in presence of twp witnesses.
