...'I'o l whom it may concern:

Be it known that I, Manns L, Lisowski, a citizen of the-Un1ted States, residing in Cranford,.in the county of Union and State of New Jersey, have invented certain new and useful Improvements in 4Apparatus for AForming Concrete Fabrics, of which the following 1s a specification. 'i

This invention relates to apparatus for use'in, the construction of buildings,I columns, girders, floors and other fabrics, of 'plastic material and, particularly, has reference to 'pparatushaving collapsible .or knoclbdnx characteristics capable of bein shaped tj. ny form desired and extender ,to any degree desired, and to have a variety of predetermined structural featm'es of novelty.

Among the objects of my invention may be noted the following: to proif'ide separable or collapsible and relatively adjustable forms adapted lto the construction of beams, girders, floors, slabs, colun'ms for buildings vand other fabrics; to provide a combination of forms, braces and tying members capable of being adjusted and readily separated for knock-down purposes and adapted for the uses heretofore noted; to provide forms for plastic-material which are simple in construction, strong, durable and effective in use to save time, material and labor in the construction of various fabrics, such as noted in the foregoing; to provide forms for plastic material, adapted for many uses, which are economical and capable of being quickly set up and knocked down and used for different forms of structures in the same building or fabric or in independent fabrics; to provide' forms for plastic' l'naterial adapted for the uses and purposes hereinbefore Set forth which may be used over and' over again and the parts of which may be' quickly repaired and. replaced without unH due expense or delay; to provide improved means for connecting the various elements of the apparatus rendering said elements adjustable in different ang-ula; directions and capable of heilig quickly set u i or built in the forni desired to be given to tlie plastic material and quickly knocked down or stripped from the latter when it has become set; and to provide certain simple, econoniical, strong and durable features of construction of the. various parts of the'forms and connections enabling the latter to fulfil the objects set forth in the foregoing With the above objects in View and others \\'l-1ich'will be detailed during the course. of this description, my invention consists in the parts, features, elements and combi- ,nations thereof hereinafter ,described and claimed.

In order that my invention may be clearly understood, l haye provided drawings wherein:

Figure l is a sectional elevationof a fragment of forms and concrete construction, in this instance illustrating a Hoor of a building, and including th temporary sup- )orting structure `and forms made in accordance with my invention;

Fig. 2 is a side elevation of the left end of the structure of Fig. l looking at the casing from the right side thereof;

Fig. 3' is anenlarged sectional view substantially on the line 3f3 of Fig. 2.;

Fig. 4 is a sectional view showing another forni. of my invention, the art illustrated being similar to that at t e left end of Fig. 1; v

Fig. is an enlarged sectional View substantially on -the line 5 5 of Fig. i;

Fig. 6 is a side elevation of Fig. 7 looking lat theflatter from the right hand side, and

another form of my invention wherein the column to be constructed is circular instead of angular, as in Figs. 6 and 7;

Fig. 11 is a section substantially on the line ll--ll of Fig. 10; and

Fig. 1 2 is an enlarged sectional detail also substantially on the line 11-11 of Fig. 10.

Referring to the drawings and. particulari-y, to Figs. 1 to 3, inclusivefa suitable supporting structure is built up between the suspension girders or I-beams, one of which is illustrated at the left of Fig. 1, said supporting structure comprising cross-beams or timbers 13, longitudinal beams or timbers lo thcrcmider, and upright's or supports 17.

'0n the cross-beams 13 are laid any number of loose boards 14 which may be desired or l required; and upon boardsl are laid Clt sheet. iron`plates or strips l5 upon which the plastic material is disposed,.as required. The cross-beanis or timbers i?, reach to within a short distance o't` the I-beanis on opposite sidesl thereof. and their ends are. connected by charmel irons 1 which constitute the supporting means for the formplates and 3 whichare. respectively7 connected to the outer sides of the channel irons i by means ot bolts or other removable devices. The, torni-plates 2 and 3 depend parallel with the adjacent I-beam and overlap the upright members ot' angular 'tormplates 5 and 4. the horizontal members ot which extend toward` and overlap. caen other. Thus. a verti -ally extensible, as well as laterally eXtensible. torni-casing is produced into which the plastic material is tilled around the I-beam. ',l`o the bottom ol each ot the channel irons is detachably bolted a depending brace-member the same extending parallel with form-plates 2 and 3 and telescoping the U-shaped. in cross-section. brace-memlwrs T and ll. respectively. The member 7 has a flat extension E), at a right-angle thereto telescoping thev horizontal U-shaped` in cross-section. member S ot' the lnace-member ll. Theseveral members t-78-fl and (3-11 are connected together detachably by means o'tl pins l0 passing through registering and correspomling apertures in the respective members. thus enabling the members and ll to l i adjusted vertically on the members (i. and the members t5 and t) to be adjusted horizontally relatively'. in order to correspond with the size and shape ot' the tormplates. as will be readily understood. To provide an auxiliary 'support tor the tormplates and brace-members.` l employ U- shaped wires 12 which are bent around the I-beam and the lower. tree endsot which are bent at an angle under the lower member- 8 and upwardly parallel with the saine. as shown in Figs. l and 2. the same thus sustaining a goodly portion otl the weight ot' the apparatus and relieving the connecting pins and bolts of undue strain. Along the length ot' the structure and ot the I-heams. viewing Fig. 2. it may be necessary to couple together a plurality ot form-plates and brace-inemhers. in order to carry out lengthy work. To accomplish this. I provide coupling bars '2O which may be dctachably bolted to one ot' the channel irons within the channel, as shown at the right of Fig'. Q. and extended over into the channel ot an adjacent channel iron behind one or more angular guide members 21. which are bolted to the bottom ot the channel iron with sutlicient space between the sann and the web-ot the channel iron to enable the bars 20 to slide freely, but be held snugly. By this means more or less ot' endwise. adjustment ot the form-plates and brace-members can be complished. This torni of my apparatus is parti en la rl y ada p and incasing they girders or I-beam supports. In Figs. 4 and 5, I have shown another form ot' my invention wherein the transverse timbers 13. loose boards ll and channel irons l are all similar to they corresponding features ot' Fi l. Likewise. in this figure7 the auxiliary or supporting wires 12. the I-beam, and the torni-plates 2, 3. -l and 5 are the same .as in Fig. l. Instead ot' forming the brace-bars or members ot tlat metal, as in Fig. l, I have shown the same as being formed ot circular. telescopic members Z2-23, 2st-25. 2(3-27 and 28; that is to say7 the member 22 bolted or otherwise secured to the adjacent channel iron 1 and telescopes the tubular member 23. the latter two being adjustably I connected together bypins ll) passing through corresponding apertures in the members. The member 2t is right-angular in t'orm and l for floor construction telescopes the member 23 and also themember '25. connection and adjustment being provided t`or by pins l() passing through corresponding apertures in the parts. An angular member 2G. similar to 24. telescopes the members and 2T. connection and adjustinentbeing provided by pins l() passing through apertures in the members. 'lhe member 2S telescopes the member 27. adjustable connection being had by the pin 10 passing through yapertires in the members. By this means adjustment in different angular directions can be made t'or increasing both'the width and the depth ot' the mold. In this torni. I preferably apply between the torni-plates. and the respective brace-members about the same. beams or boards 29 which act as additional stitfeners in case the cooperating members are spaced too tar apart. This gives stability to the torms and makes the apparatus very rigid. In either form ot my invention the mold trame is composed ot the members indicated by the reference numerals 2 to l1. inclusive. Figs. 'l to 3. inclusive` or the equivalent members iu Figs. 4' and 5. coupled with brace-boards 2t) in the latter figures: and the horizontal' members o't' the mold trame provide a plattorni t'or the members l and and the boards 29.

In Figs. G to t). inclusive. I hare shown another form ot my invention whereby I may Jform angular columns or beams. either with or without interior Stiieners. Isuch as the V-shaped central. I-beam members. which. as shown. arebent longitudinally and placed with their vertices together. Abtn these cent-ral stitteners I apply my right-angular in .cross-section and.tlie..jmem

bers of which overlap each other. wlierebv lform-plates 3P and 39, 40 and ll. which are form-plates, l provide Y-shaped stillening beams or braces, the prongs ot' which substantially parallel the respective formplates, and the webs 30 of which extend tangential .to Ithe angles of the form-plates. ln this instance of my invention, the bracemernbers indicated at 31 and 32, and which .pass through apertures in the webs 30, are

circular in form andare disposed at the angles ofv the frame or mold. At opposite ends, the said members 5l and telescope 4nection with the Fig. 4 form of my invention.l Longitudinal extensibility of the corner brace-members is provided 'for by the coupling bars 34,* Fig. G, which are U- sliaped in cross-section and which embrace the Webs 30 of said brace members, being ctapled thereto at opposite ends by bolts or pins, ashereto'tore explained in connection with Fig. 2. It will thus be seen that 'colr `ms, pillars and beams of angular form c i be produced from plastic material through the medium of my apparatus with great facility and economy ot time and labor, and that the apparatus can bc quickly set up and knocked down or stripped from the plastic material when 1t has become set.

In Figs. '10, 1l and l2, l have shown a form of my invention capable of producing circular columns, pillars and beams, and therein the several form-plates 36 are made' in the form of segments of a circle and of such width as to enable them to be ovcrlapped for contraction and expansion in the same manner as described with reference to the other forms. At the center ol2 eachk of the form-plates, I provide longitudinal braces which are substantially T-shaped in cross-section, the webs 35 of 'which are )rovidcd with slots or apertures, as shown in Fig. 10, through which pass the bracemembers 3l' which encircle the form-plates, and, at their ends, overlap and are adjustably connected together by means of apertures and pins or bolts, as heretofore explained.l The heads oi the lance-members, or those portions extending at a right-angle to the Webs conform more or less to the form-plates 36 and operate to effectively brace the same vand hold them in place. lith this form ot my invention, it will be readily understood that l can make a pillar or column form ot substantially any desired' diameter. Longitudinally ol the structure, the webs 35 should be coupled and adjustably connected through the Inedium of U-shaped bars 34, as indicated in connection with Fig. G.

-From the foregoing detail description, the mode ot' operation will be readily understood; that is to say, structural supports, such'as 17, lf3, 13, lll and 15 will be set up between girders or beams if a flooring is to be laid in buildings, and the channel irons l will be set in place as described. Then the supporting loops 12 will be laid over the I-beams and the form-plates properly adjusted, whereupon thelbrace-members (i, 7 and 11 will be Set in place and properly adjusted. The cement may now be poured or slioveled in and allowed to set. In forming a column, post or beam of angular term, such as shown in Figs.l 6; and 7, the structural iron cores, Whatever they may be, will be surrounded with the.'

formplates

38, 39, 40 and 4l., boards Q9 seb in place, if it be desired to use the same, and then the corner brace-members set up and surrounding brace-members applied, as will be readily understood, adjustments being made of the various form and brace-members vto accord with Jdie size of structure desired. The plastic material will then be pouredin, as shown; The same procedure will take place with reference to the apparatus shown in Figs. l() and 11, in'all instances longitudinal adjustments ot' the ln'ace-members being accomplished through the medium ot the coupling bars 20er 34, as .the case may be. It will be seen from the structure and mode of operation described that, when the plastic material is poured into theI forms or molds, the latter will be forced downwardly or expanded to their proper positions under the limitations imposed bythe ln'ace-members of the apparatus, it being understood that the forinplates have no n'iechanical connection but overlap each other loosely. Economy of time, labor and material are direct results oll the use of my structures, which latter. comprises` theV automatically adjustable or extensible form-plates which are braced and lirmly held within predetermined limits by the brace-members, and which latter may be adjusted in different angular directions to increase or decrease the size of the form and the structure to be produced therefrom. The apparatus is also adjustable yior differences in distances between girders, uprights and length of girders; and any shape of column, beam, and any kind of straightaway or angular structures can be producedby the use of my apparatus.
