Y

The walli ot' the mold 'is also formed ot' ,aplui'ality votnseclioiis and cach section is provided ai oneeud with u bar of wood or other suitable material ,l2 secured' along its edge .and formed ivith a beveled edge l?.

yThe end of the abutting sec-tion ot the wall is also provided vv-i'tl-i a similar liar lY-lY having an edge beveled to 'correspond with and match. the lievel ,i3 on the other liar.

The ends "f the sections of the inner wall of the mold are secured together by providing angle bars .l on the bars 12 and 14 and connecting vthe' same by -bolts 16- passing through openings lin theangle bars. y

To support the mold wallsin position for .with a hook 33 to engage' an opening in an forming the upper sections of the concrete wall, a supporting mast 17 is erected at the center o f the proposed structure. This mast may be of any suitable constructionand of a greater height than the desiredheight of the structure. .A s shown in the drawings y this mast v'consists of four wooden bars or the poles 18 which are preferably 'rectangular in cross section and a're set equal distances apart and form the four corners of the mast or column 17.*' Thisl mast isfheld firmly in position while the work is goinl on, bya oot anchor shown in Fig. 8. T is anchor consists of fourmeinbers-or planks 20 set oii edge and-'each provided at one end with a strip 21 extending parallel with the end of lank andforming a loop to receive one of t eother lanks. These plank members are thus inter ockedto form between them a rectangular box of horizontal dimensions equal to .the cross sectional dimensions of the rectangularl mast which is made up of the four members, one member. of the :mast being set in each corner'ofthe box and the box then filled in with cement or concrete to `firmly hold them in'place. |Wedges 22 are iriver; into the looponeach lank to bind t ie' planks in position and tie outwardly 'f-'tentling ends of the planks abut the wall 1 "ig. 1) of the structure and center'the mast sprein. After the structure is com leted ind itA is desired to remove the-mol and supporting mast, the wedges 22 are knocked out and theA yplanks may removed from the' foot of the mast to rrelease the same.

The inner mold wall 2'is supported in position for. use by rectangular shaped cross beams 23 set at right angles'to each other and of a size to lit between the four bars18 kforming the mast. Each bean'i is provided with a reinforcing member 24- to strengthen the saine at its points of intersection with the other beam and each beam is 'supported a sliding extension bar 25 supported u on the upper edge of the beam and guide thereon by a strap26 secured to the inner end of the extension and carryng'a roller 27 engaging of the beamV A guide fork 28 on eachend of each beam carries a. roller 29'engagng the under side of the 'extension bar 25 and said fork extends upward in engagement wit-ii the sides ofthe extension bar to guide the same in its inward and outward movement on the beam.v All upwardly extending lhook 30 (see-Figs. 1 and 4) on'the outer end of 'eacl 1 'exteizsion bar engages an opsm then be readily.

- usted' upwardly alon upon the outer ends of the lower side'l ing in aniangglel bar '31 secnrcd along the` lower edge ot each section of the inner wall 2 oit' the mold to support said sections upon the extension bars and ldet-achably attach' the same tlieleto.. A bracket 32 secured u pon each extension bar lextends "upward-ly tierefrom and `is provided at its upper end angle bar 3i securedalong the npper'cdge of each section-'of the inner .wall ot' the mold and detacliably hold the -upperedge o't the section. Each sec-tion ot the inner wall of theI mold is 'thus-carried upon'one ot' the ex tension bars so tliat-by'an inward movement of the extension upon the beam the'section of themold wall may be moved inward away' -from the concrete wall and said section wi l at the same time be supportedfin 'position to be raised into posit-ion for forming another portion ofl thel struct ure.

Securing bars or beams 35 arranged at right angles to each other and of a rectangin lar cross section to tit between the members of the mast are roi'idedl and positioned at such'a distance a )ove the beams 23 that the 'workmen niay'conienien'tly stand erect upon said beams beneath the beams 35.4 The beams 35 are provided with .reinforcing bars 36 and extend radially outward some distance above and beyond the' up er edge of the nio'ld. The outwardly extending ends 'of the beams-are notched to receive loops 37 secured upon the upper end of the hang c'rs 11 and adjustably hold the hangers in posit-ion to properly si pport the outer mold wall'. 4The beams 2 and 35'aradjustably held in position between t ie four inembers of the mast by `clamping blocks 38V engaging the outer sides oi! the members ofthe mast and drawn inward toward' each other byibolts39 extendin r through the blocks and between the mem, rs ofgtlie mast, thus when the nuts on the bolts are turned up. forcin said lmembers toward each other into firm rictional engagement with the sides of the beams and into the angles formed by the'meeting'ofcrossed beams.- Each 4setof' supporting beams is thus frictionally/,Ii''ld in any position towhich` they may be adthe mast and by oosen-ing the nuts on tie bers of the mast may bets rung outwardly' bolts 39 the 'inei'nf and 'the beams slid upwar ly between them l v to raise the mold.' To s'o raise the moldinto iton for forn'r'ringl anotherportion of the wall of thestructure, the beams 23 and 35 are connected by a ratchet bar 40 secured at "its 4ends to the'beams and extending vertically in the center of the mast-between the four members forming said mast. -Bearings 41 are adjust-ably clamped to two of the 'four members of the mast by clipbolts 42 so that said bearn maybe readilyadjust'ed to any desiredpositionupward or downward alongthe mstg. A"rcker bar'43 is provided havriestwo pawls' 5 pivotally attached tothe Acarrying beams and bar in position to engage the ratchet bar l0. IIhese pawls -L are each weighted at' one engagement 'with' the ratchet bar. Outwardly extending'handle portions LL6 ontlie rocker bar are provided for rocking said bar to alternately engage the pawls with the notches ot the ratchet bai' and raise the upward along the ng blocks are released four members of side so that they will be normally held inmast, when the clampi to release and spread the the mast-from tiictional engage-mentwith the beams.- Y

It may be found desirable to forni a. tapering wall, as for instance, in the construction ot' chimneys and it may also beV desirable tol -orm the 'structure rectangular in plan view.- Such' a construction is illustrated in Fig. 9", the outer wall 4T of the 'in-old being formed tapering and made in sections there being integral corner sections 48 and intermediate sections 49 Fitting between the corner sections and having beveled side edges overlapping similarly formed side edges on the corner sections.A The intermediate sections 49 are'held in place by strips 50 secured to the edges of the corner sections. When a mold having a tapering wall-oi this characportion justv fio teri's raised to forni the next portion of the structure it becomes necessary to contract said wall sutliciently to bring its lower edge into engagement with the upper edge ot the formed and to do this the intermediate sections i9 may be replaced by others of lesser width. It found desirable, the intermediate section of the outer mold wall may be formed tapering as shown at 5G in Fig. 6.

es shown in Fig. 9 the 'inner mold wall 51 mat also be made up of corner sections 52 and intermediate sections 53 formed with beveled side edges 'engaging similarly formed edges on the corner sections, and the intermediate sections in place by strips 54 secured to the corner sections.' In this construction of inner wall, said wall is collapsed to disengage it from'theconcrete wall by :lifting the intermediate sections out verti- .cally and if found desirable said sections may be formed tapering as shown at 55 in Fig. 7 to'assist in their release.

The entire mold structure is thus carried center mast of a height equal to than the desired height of the structure to be formed and-by means of the .pawls and ratchet the ywhole mold structure may begquiclrly` and easily lifted and ad# justed upon the mast. The supportingl beams 4which carry and support the mold also form a scaold for the workmen and a very cheap and convenient adjustable mold for forming vertical walls is secured.I
