In said drawings: Figural is an elevation of a mold for columns in which my invention finds emhodiinent. with the sustaining frame therefor shown in section. an enlarged detail section of the ring at the upper end of the column section of the mold. and the hraehet forming the base support for the (-olnmn head of the mold. Fig. 3 is a vel'lii'al set-.1 ion of a modification of the joints of the eolumn portion of the mold. Fig. 'lis a top plan view ol the frame for sustaining; the (-olnmn head portion of the. mold. in its operative position. Fig. 5 is an enlarged detail seetion of the sustaining Frame of th mold showing the means for connwting it with. the column head. portion of the mold. Fig. 5'' is an enlarged vertiral transusrse section through t portion of the eolumn head and column of tho mold. Fig. 7 is an enlarged detail section thereof more clearly showing the means by which their several parts are conueeted and adjusted. Fig. 8 is an enlarged elevation of the mold taken on a line at a right angle to the view thereof shown in Fig. 1. Fig. l is a detail transverse seetion taken on the line 9-9 of Fig. 1. Fig. if is a detail section taken on the lllt'jllllili line lll ltl of Fig. 9. Fig. 11

is a top plan. view of the column section of the mold taken on the line 11-11 of Fig. i). Fig. 12 is a transverse section taken on the line 12-12 of Fig. 1. Fig. ll is a detail showing, the clamp in side elevation in its operative position, and Fig. H. is a top plan view o l the sectional column showing a inodilied means for adjusting it; for forming columns of diliering diameters.

Similar characters of reference indicate the same parts in the several figures of the drawings.

;\n important consideration in the corn strurtion of molds for columns and heads for unlimited repeated use is that their body portion shall he eonstrluzted of galvanized sheet iron of minimum thickness consistent with strength, rigidity and durability. in this eonuection it is therefore proper to ohserve that with the use of the strengthening: and vonnectint: devices for looking); and su taining the mold of my invention in its operative position, the body' portion of both the i'olumn and head forming members ol m mold may he. and are in practice formed from galvanized sheet ironasthin as twenty gage. and with the result that: this thin- Fig. is

shoulder 22 and a seat ness of sheet iron furnishes a means, as will hereinafter be described, for adjusting the mold of my invention for producing differing sizes of columns.

he body of the column mold may and is shown to be in two lengths 15 and 1.6, one of which lengths telescopes in the other as indicated at H, and with a lit so close that owing to the thinness of their metal, the molded colpmn opposite their joint will be seamless, and are divided longitudinally into two se1'nicircular sections, reinforced (see Figs. 1, 8 and 9) .respectively by means of detachable angle iron bars 19 and 20 extending longitudinally thereof.

As a means for preventing the meeting edges of the opposing sheet metal sections from forming either a longitudinal raised bead or groove in the molded column, one section is provided with a longitudinal 23 for the edge of the opposing section formed by bending the metal thereof outwardly at a right angle while the opposing sheet metal section is bent upon itself as indicated at it so that when held against the shoulder 2:2, in contact with the seat 23, the inner surface of the mold will be substantially continuous notwithstanding its sectional construction. To provide against the possibility of the cement being forced between the joint formed by these meeting edges when subjected to unusual or excessive pressure, the opposing sections of the column mold are also respectively provided with flanges 25 and 26 projecting between and across the opposing surfaces of and whereby they may be clamped between the angle bars, as hereinafter described, one of which flanges terminates at the outer edge of the angle bars, and the other some distance outwardly therefrom whereby it may be bent over the other flange and the .edge of the angle bar adjacent thereto as indicated at 27, thereby capping, and to'tliat extent'furnishing a seal closing the outer end of the opposing joint.

Flanges 25 and 26 (see Figs. 10) are provided with registering open slots 21, and the angle irons 19 and 20 with registering perforations through which to project a bolt 28, provided at one end with a head 29, and at its opposite end with a hook 30 bent therefrom, opposed by a wedge 31 for drawing the angle irons toward each other, and thereby clamping the flanges 25 and 26 between them tight enough to form a water tight joint, and to which end the wedge is supported by the bolt, and tightened between opposing bearings and the surface of the angle iron adjacent thereto. As shown in Fig. 1, a number of these bolts may be employed at intervals sufficiently frequent to insure such a water tight joint throughout the length of the two sections, and of such other and further secformed by the hooktions as may be desirable or necessary for the purpose of the column to be molded therefrom.

The sectional column mold above described, is reinforced a short distance below its upper end by means of a correspondingly sec tional angle iron ring 32, secured thereto by means of rivets 33 counter-sunk in the inner surface of the mold sections. the outwardly projecting flange of these reinforcing angle irons being also provided at suitable intervals with elongated perforations 38 (see Fig. 11) through which to project bolts 3+.

The body of the column head member for the mold in which my invention finds its embodiment is also constructed from thin sheet metal 35 of the character before described for the column mo l, and like the latter is divided verti rally see Figs. 6 and 7) into two jointed sections 36 and 37, to the upper edges of which is secured a sheet metal ring 38 by means of rivets 39, and reinforced by an angle iron consisting of sections 40 and 41 secured to the ring by rivets 42, which, together with the rivets 39 are counter-sunk in the inner surface of the collar.

Seated on the angle iron 33 and detachably secured thereto by bolts 43 is a scctional angle iron to which is secured by means of counter-sunk rivets H a sectional collar 45, the depth of which is about half that of the sections 36 and 3? of the column head mold, and which in its operative position seats at its bottom edge on the bracket 33. The sectional collar 45 not only serves to strengthen and maintain the column hen d sections against,exp-ansion, but furnishes a bearing surfaceand a support maintaining the upper edge of the column mold in closely fitting contact with the bottom edge of the column head mold, and whereby the column and head members of the mold may be detachably, rigidly connected and suspended from a suitable super-structure of wood hereinafter described.

For removably connecting, adjusting and locking the column mold 15 to the column head mold 35, bracket plates 40 and4i' are respectively externally secured toward the upper end of the column head mold 35, and to the sectional collar 45 at the opposite sides thereof by means of rivets 48-48 countersunk .-in the inner surfaces of both of these members, the outwardly projecting ends of which brackets are per orated for the reception of a screw-threaded bolt 49 passing therethrough, provided with a nut 50.

As a means for preventing the lateral expension and bulging of the thin walls of the column mold from the weight, and particularly from the force of impact imparted thereto by the gravity feed of, and the usual ramming down of the concrete in the mold, m invention includes the employment of detachable clamps of a very cheap and yet novel construction, adapted to encircle the column mold at such intervals of its length as may he necessary to these ends.

The clamp ahove rel'erred to (see Figs. 1, l2 and lil) consists of opposin; seglncntally cinned ilat metal liars 51-5' spaced apart at their opposing; ends and connected at one side by curved hars 535 l respectively rigidly secured thereto by rivets :J:l-;):l,, the meeting ends of which liars are hinged by overlapping their ends and pivotally conncctine them h v means of a rivet or holt .36, the ends of the liars at this point hein g spaced apart to straddle the longitudinally reinforcing angle irons for the column mold. Secured at a point shortly remmed from the opposite end of the curved liar .32 |i means of rivets Si -3T is an outwardly (lll'Htl liar 3h, overlapped at its l'rcc end lay a har fill hinged to the liar 5H in means of a rivet or liolt (it). The opposite end ol the liar Jil overlaps a curved hand lc\cr til. which at this point is provided with a series ol' perforations Hi -(i2 For the reception of a holt or screw ill and thcrchv providing a means for successively l ltllllt .\lllg the walls ol' the mold to force out bends. and other irregularities thcreiih and conform the walls to the circular contour ol' the opposing hearing surfaces of the clamp. The lever til is provided at its end with a pcrl'oration ill, and the curved har .31 with a plurality of perforations U5. whcreln when the clamp is tightened upon column molds dillering in diameter, the lever ma v he locli'cd in its operatire position h moving its perforations til to register with one or the other of perl'orations on as ma lie on projecting a wire nail or other pin thcrethrongh.

In Fig. it is shown a niodilication in the form of the joint connecting; the opposing sections of the column mold. aml whereh the llexihility ol' the thin sheet metal l'rom which the sections are l ormed is utilized for adjusting the mold to a smaller size of column, and to which end one ot the mold sections tilt is normally smaller than the opposing section (37, as indicated hy dotted lines in Fig. it. and sprung into locked engagement alone one of its longitudinal edges with the smaller section (36.

For forming a close joint, hetwccn, and at the same time locking the opposing sections together at one edge while springing the larger section of the mold inwardly to the smaller sizcd section, the sheet metal of the section 134' for forming: one hall' of the. smaller sized column is first hcut hacluvardly upon itscll' at UH thence outwardly at (it), and then at a right angle 70. there l'ormine a channel iron. one llange of which formed h) the hend (h is adapted to lie projected into a recess t'oi'mcd Irv an outward hcnd Tl, whence the metal is heat at a right angle thereto, as indicated at T2, and llltl't'llj to the form of an angle iron fitting the before described channel iron in the smaller mold section (56.

The hends just described not only provide for maintaining, a close contact between the edges of the two sections, and a substantial continuity of their inner surfaces, hat to provide a hinge connection sustain me one side of the sectional mold in its operative positioin while springing: the larger section to lo ked engagement at the opposite side with the smaller section. and at which point the sheet metal of the section HT is licnt liacltwardl upon itself as indicated at TIL thence outwardly at Ti and at a right angle at TI to precisely the same form as the edge ot' the smaller section no is heat at the tllllolslll side of the mold. ()n the other hand opposing the construction last descrilied the metal of the smaller section is lienl outwardly at TH and provided with a [hinge ii to precisetv the same form as the cde'c f tin: larger section at the opposite side oi lhc mold to form a lock joint on compre the outer section from the position indicated in dotted lines to thatshown in the full lines. In short the modiliatlon shown in hi it provides a means li v which a larger rttlltlll ol' the colnlnn mold may he. heat to torn: the continuation of an opposing smaller section for the purposes of redni-in e the diameter or size of a column without haiiug hoth sections therefor normally l the same size. It will now he ohserved in this reduced size of mold. section oincces aiil l'orms less and section GT more than one-half of the mold, the circular form of which is produced and maintained h v the reinforcing clamps when correspomllnglv adjusted. and this owing: to the fact that the construction of the clamps provides for their adjustment to two circles ditl'ering' in (iiamctcr. and this is none the less true when the section HT is moved to its lochcd position with the section (it; by means of the adjusted clamp. or is adjusted thereto following the bending of section (3T h hand to its locked position with the section (at For locating and snstainin; column molds for concrete in their operative position, it has hcretot'orc been the practice to drive nails at Frequent intervals thercthro ugh into the false wood work for the concrete ceiling or lloor ol' the structurcol which the column is a part and which is ohjectionahle not only lic ausc of the injury to the mold for repeated snlisequent use. and the time and dillicnlt v ol' detaching the flooring ot' the false wood work therefrom, hut for the further and more important reason that the surface of the column or column hca L as ma v he, is marltcd and marred li "the nail heads and not inl'rcipientlv liroken when detachin; tie and l. \s a means for avoiding these olriiwtims the false wood ceiling or its absence for the flanges of the angle irons joint may be lifting of the column floors 78 (see Fig. 1) is supported by an open frame consisting (see Fig. l) of side bars T9-7J connected by, and bars 80-80 extending at a right angle thereto, and with bars 81 at each of its four corners to the inner surfaces of which are secured angle irons 82-82 projecting inwardly therefrom in vertical arrangement forming seats for the sectional flange 40 and ll of the reinforcing ring for the column head, and in 3?) at the upper end of the column mold, and whereby the column head mold, or the column mold as may be, is centered and suspended from the adjacent false flooring of the false wood work, and so that a close formed between the column and the under-surface of the concrete ceiling or floor.

As a means for preventing the accidental head mold and the upper section of the column mold as may be, from forcing the lower column mold sec- ,tion upwardly, there may be nailed to the lsuperstructure a. flat, preferably sectional firing 83, either of metal or wood, projecting over and against the opposing surface of the reinforcing angle iron sections 40 and 41.
