MOLD FOR CONCRETE COLUMNS.

To all fic/lm, t may concern:
Be it linoivn that l, Dirvm Bnlx'r'rnn, a subject of the Emperor ot Austria, having declared my intention of becoming a citizent ot' the United States of America, residing in the borough of the Bronx, county ot Bronx, city and State ot New York, have invented certain new and useful improvements in Molds 'for Concrete Columns, of which the following is a specilication.
This invention relates to molds for concrete columns and aims to provide improvements therein.
rlhe tamping which the material in concrete molds receives requires that such molds, and especially their lastenings, should be stoutly made. ltloreover, the plastic nature ot the material placed in the molds frequently has objectionable etlects in clogging up parts of lthe fasteners, as, for example, the screivthreads'upon parts of fasteners.
The present invention provides a mold for concrete columns, which is well adapted to stand the strains incident to the Work, which may be put up and taken down with a minimum of eti'ort and time, which may be very simply constructed, and the parts of vhich are not seriously ali'ecteril by becoming smeared with the plastic cement or concrete, and which, moreover, requires the use ot the simplest tool, viz: a hammer, in erecting it and taking it doivn.
An embodiment ot the invention is illus trated in the accompanying drawings, and the invention will be more fully explained in connection with said drawings.
In said dravvings Figure l is a View in elevation of part of a mold for a concrete coliunn, parts being broken away and shown in section;
Fig. 2 is a transverse sectional View on the line H ll, Fig. l ,g
Fig. 3 is ay verti al sectional vieu7 on the line lll lll, Fig. i;
Fig. is a vieiv in elevation parts oie the mold.
The mold is preferably made in tvvo'longitudinal sections 1 being preferably formed of sheet metal, and having angle iron strips, 2 2 riveted tl ereto at their longitudinal edges. The inside st the mold is preI'er-ably counter-sunk at the riveted holes, so that the rivets may be flush with the inside ot the mold, as indicated 3, if
The mold may also have extensions at one or both ends, the extension, or extensions, com prismg longitudinal halfsportions 4 4, similar to the portions 1 1. The portions 4 4 are preferably provided at their edges with angle iron strips 5 5 similar to the strips slots 9, and through these slots 9 are passedl These Wedge pieces` in Wedge pieces `l0. I conjunction with the keys 7, hold the strips of angle iron 2 2 and 5 5 together, and consequently hold the halves of the mold 'to-v gether'. To draw the strips 2 2 and 5 5 tightly together, it is simply necessary to tap on the wedge pieces l0 with a hammer.
These keys 7 have greater strength than bolts, and the fastening means as a whole have practical advantages over bolts, inasmuch as there are no threads to become clogged with concrete, and, even it the parts are clogged, both the keys and wedge pieces may be readily forced into position with a hammer. Moreover, a hammer is the only tool necessary in connecting and disconnecting the fastening parts of the mold. lt is not necessary to use a "wrench, as is usual at present.' Moreover, the manipulation ot lixing the fastening parts 7 and 8 in position, and disconnectinfr them, is very readily and easily effected, and agreat saving' of time effected in setting up the molds over molds at present in use.
ln order to brace the mold circumferentially, annular braces il are provided. rlhese braces le are preferably ot angle iron and are preferably made in two parts l5 and 16, the parts having projections 17 at their ends. The braces 14 are preferably placed around the parts 1 1 of the mold, and also the parts l at their top and bottom, and also at suitable places in between, where desired.y The portions l7 i7 of the brace portions 15 and 16 preferably embrace the upstanding portieri of the angle iron strips 2 2 and 5 5. The angle iron strips 2 2 and 5 5 sey
