as disclosedV in Patent No.1,560,293, one

sect-ion extending along 'each wall' of theA length` of the wall;

Each 'section of y wallcfthe building comprises a wall form building, and each i section V'ma'ybe the entire "or: mold1 proper `including v'the inner` and the apparatus lfor vone outer side plates 10 of sheet metal, wood ory other suitablematerial. Said plates are of suitable height to define one course of the wall' and said plates may be in sections se-4 cured together end toend in any suitable manner.

The side plates 10 are supported by hangers 11, which are of. angle iron as shown, and which are bolted or otherwise secured to said plates Vwith the upper terminals of WALTER THEoDoR EELS, oF `Naw YORK, iv. y., AssiGNon To FELSTQNE FIREPROOF,

said hangers projecting above the upper edges of the plates for connection with the yokes or cross bars 12 .extending trans` versely over the plates at suitable intervals longitudinally of the form. The upper ends ofthe hangers 11 are pivoted by means of bolts 13 to the yokes 12, said yokes having longitudinal Series ofv apertures 1li to receive said bolts, whereby the plates 10 may be i spaced apart different distances for producing walls of differenttliicknesses. kThe yokes 12 preferably have numb-ers or other indications above the apertures 1st in order that Vthe hangers may Lbe readily adjusted for producing a wall of desired thickness.

The yokes l12 are provided at their opposite ends with arms 15 extending down wardly at obtuse angles, and means are provided between said arms 15 and hangers 11 for swinging the plates 10 toward and away from one another. The arms 15 have Sil circular heads 16 at their `.loweriends provided with diametrical apertures 17 there,`

through in which screws 18y are swivelled circular wallsof the heads 1G to permit the screws 18lto swing in the vertical planes of the yokes 12. The screws 18 have cranks 18" above the heads 1G for conveniently rotating said screws, and vlhe lower terminals of the screws are screw-threaded within sleeves or velc'ingatedv socket nuts 2() which have their lower ends pivoted, as at 20, to the lower terminals of thehangeis 11.` Thus, by rotating the Screws 1S,`the plates 10inay be swung toward and away from one anV other, andlthe screws S'may' oscillatein the apertures 17 which Vare siiiiiciently largeto permit of such oscillation; The screws 18` and sleeves or nuts4 2O provide extensible and' arms l'enable the plates 10 to be swung for rotation, nuts or collars 19 being secured away from and toward the wall with considerable torce.

The form or mold is supported directly and solely from the wall which is under construction, without usinga special framework, therebyproviding a simple and convenient construction, to save time and expense. F or this purpose, vertical screws 21 are provided and serve three purposes, namely v the form or mold proper is supported by the screws which are supported. from the wall under construction, the screws are employed for raising the form or mold as cach course 1s completed, and Ythe screws serve to guide the lorm or mold vertically so that the wall is plumb. Each screw has a smooth lower terminal 22, and has a head 23 ot' square or angular :torni at its upper end, and the thread of the screw has its convolutions spaced apart in order that the screw may be unscrewed from the concrete or other plastic composition as will hereinafter more fully appear'.

Each yoke 12 is supported from one ot the screws 21, and for this purposel a nut 24 is litted snugly on each screw, and is swivclled to the intermediate portion ot' the corresponding yoke 12 between the hangers r11. The nut 24 is journaled for rotation' within a bearing with which the yoke 12 is provided, one hall or section 26 ot' the bearing being integral with the yoke, and the opposite hall' or section 27 being secured to the section 26 by bolts 28 or other clamping elements, said sections 2G and 27 complement-` ing one another and embracing the nut 24. 'llhefnut 24 has a lower flange 30 abutting the' lower end of the bearing 26-27, and the nut 24 is provided near its upper end with an integral ratchet wheel 31 seating on the bearing.

In order to rotate the nuts 24V oil one section of the apparatus, alever 32 is mounted for rotation on the upper end portion of each nut 24, being swivelled and confined between iheratchet wheel 31 and a retainer ring 25 secured on the nut. A spring-pressed pawl or dog 33 is carried by the lever 32 at the lower surface thereof to engage the ratchet wheel 31, in order to rotate the nut. 24 in a direction to climb upwardly on the screw 21 when the lever 32 is oscillated.

The levers 32 of each section'of the ap-r paratus are connected by a bar 34 so that the levers of one set may beoscillated simul-l taneously, to cause all ot the nuts 24:01 one section ot the apparatus to climb simultaneously upwardly on the screwsy 21.

The oscillation of each lever 32 is limited by means of a stop bar 35 extending' below the lever 32 and having depending stop lugs 3G at vits ends to contactwith the yoke 12, said bar 35 being 'secured to the lever 32 by means of bolts 37. Y

In order to prevent the` reverse rotation the course 43.

of the nuts 24, va hole 38 is drilled in each bearing 26-27, preferably in the section 26, and a ball 39 is disposed in said hole so as to wedge between the nut 24 and opposite wall of the hole 38,A as seen in Fig. (5, to prevent the reverse rotation of the nut, but permitting said nut to rotate in a direction to move upwardly on the screw 21. A coiled spring 40 is confined beween the ball 39 and an adjusting screw or plug` 41 screw-threaded into the hole thereby holding the ball 39 in place.

The apparatus is used as follows: The lower ends 22 o1 the screws 21 are inserted in recesses or holes provided in the base or foundation 42, as seen in Fig. 4. The screws 18 are then rotated so as to move the 'plates 1() to vertical position, and the screws 21 are then adjusted so as to be plumb or vertical with careful accuracy, in order that thev wall will' be started upwardly plumb. The concrete or grout is then poured between the plates 10, with the form or mold heldl firmly in position, thereby producing the lirst course 43 on the base or foundation 42. lVith the form in starting position as seen in Fig. 4, the plates 10 contact at'their lower edges with the base or foundation and the nuts 24 are located intermediate the ends of the screws 21, with vthe screws projecting upwardly above the yokes 12. 1V hen the lirst course 43 has been poured and has set suliiciently so as to firmly .support the screws 21, the form is then raised so as to enable the next course about to be formed. The nuts 24 are rotated by reciprocating the bar 34, so that said nuts climb upwardly on the screws 21, said screws having their lower portions embedded in The bars or yokes 12 and plates 10will be raised with the nuts 24, the screws 18 having been previously rotated sogas to swing the plates 1() away `trom the opposite surfaces ot the course 43. This permits the i'orm to be raised conveniently wit-h the plates 1() spaced from the concrete.

VlVhen the nuts 24 reach the heads or stops 23, the screws 18 are rotated so as to swing' the plates 10 toward one another, as seen in F ig. 2, with the lower edge portions of said plates overlapping the upper portion of the course 43. The concrete, plastic composition or grout for the second course is then poured between the plates 10 of the lorin. thereby producing the second course 44 on the course 43, with the screws 21 embedded in both courses 43 and 44. After the course has set or hardened sufficiently, the torni isagain raised to position it for the third course. The screws 18 are lirst rotated to swing the plates 1() away from one another out of contact from the course 44, and the bar 34 is then reciproeated to rotate, through the ratchets, the nuts 24. Said nuts contactlingwiththe stops or heads 23 will prevent.

.llU

the nuts from climping upwardly further on the screws 21, and the screws are therefore compelled to rotate with the nuts. The screws 21 being rotated will be unscrewed partially from the wall which is under construction. Thus, as seen in Fig. 3, the screws 21 are unscrewed from the course 43 but remain in the course 44 when the plates 10 have been `raised sufficiently to position them for the productioirof the next or third course. The plates 10 are then again swung toward one anot-her to' bring their lower edges into overlapping relation with the course 44, and the operation is repeated as hereinbefore described. The screws 21 remaining in the course 44 will support the screws and orm from said course. In this way, the screws are always supported by the last course and remain therein until the next course has set sufficiently, at which time the screws are unscrewed for the next operation. The screws thus tiavel upwardly in the wall under construction to continually support the form fromthe wall, to move the form upwardly, and to guide it for vertical movement so that they wall will be plumb. It will be noted that the screws have at least their lower halves embedded in the concrete in order to prevent the screws from inclining out of plumb, and the wall'will therefore be built up vertically provided the screws 21 are started in true plumb positions. As the screws move upwardly with the building up of the wall course after course, vertical holes or passages 45 are left in the wall. These passages are not objectionable and may be used for ventilation, electric wires, or the like, inasmuch as inlets and outlets may be drilled in the wall to said passages 45. By completely unscrewing the screws Y Q1 from the last course the apparatus is `quickly removed from the wall. It will also vbe-noted that as the wall progresses upwardly it is entirely unobstructed below the form, the apparatus being conned vto the upper edge portion of the wall. "This en- Y ables other work to be done on oradjacent to the wall as the wall is built up. l

The screws 18 at each side of the form or mold may be operably connected so as to be operated simultaneously. Thus, as shown inFigs. 7 and 8, sprocket wheels 46 are secured on the upper ends 'of the screws, and an. endless chain 4'7passes over said sprocket wheels for simultaneously rotating said wheels and the screws 18.A Guards 48 'for thecliain straddle the wheels 46 and are pivot-ally mounted on thescrewslS, to prevent the chain slipping ott'V the wheels.
