Beit known that l, DANIEL C: STAUFFER, a

citizen of the'United Statesresiding at Canton, in the county of Stark and State of Ohio, have invented a new and useful Construction of Buildings, of which the -following is a speciiication. l

This invention'relatesto the construction of buildings, and more particularly to a novel form of'mold for 4constructing the walls, partitions, `and other'portions of the building from cement, concrete, or similar plaster Inateriah The object of the invention is to provide a comparatively simple, inexpensive, and durable device of this character, in which the sev- .eral parts may be quickly and conveniently assembled and firmly maintainedin position during the molding operation, and one which will per-mit the' continuous operation of the mold during the formation of the wall.

' A further object of the invention is to provide aflexiible connection between the several mold-sections designed to be embedded inl the concrete or cementl and adapted to be cut or severed when the cement sets to thereby permit the removal of the mold-sections, said flexible connection. being lett embedded in the wall so'as to strengthen and reinforce the latter. l y

With these and otherl objects in view the invention consists in the construction and' novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto ap ended, it being understood that various cllianges'in form, proportions, and minor details of construction may be'resorted to without departingfrom the principle or sacriiicing any of' the advanta es of the invention. n the accompanying drawings, forming a v, part of this specification, Figure 1 is a side elevation, partlyin section, of a portion of a improved mold. plan view-o the same.

drawings. In constructing the cement or concrete Fig. 4

wall I'employ one or more mold-sections,

each comprising an'inner wall 5 and an outer wall 6, Said walls being reinforced and strengthened at their topy and bottom edgesv by longitudinally-disposed L-shaped angloirons 7, to which said walls are riveted or otherwise rigidly secured and which also serve to support the severalmold-sections in vertical alinement durinor the formation of the wall.

The outer walls 6 of the mold-sections are preferably oblong iri shape and stamped, pressed, or otherwise rou hened, so as to give the exposed surface' of diie wall the appeax'-, ance 4oi cut or chi )ped rock, the longitudinal v.edges of the wa s 5 and 6 being bent or curved inwardly, as indicated at S, to produce inwardly-extending flanges lwhich form depressions in the wall and serve 'to define the several blocks comprising the latter.4 ll desired, however, some of the platescomprising the outer wall 6 may be smooth or unobstructed, as indicated at 9, whereby certain ofthe blocks in the wall will present a smoothdressed surface, thereby adding to the ornamental ap earance of said wall.

v The ang e bars or irons 7 are provided with a plurality of spaced openings 10, adapted to register with each other when the mold-sections are disposed in superposed relation, 'as shownin Fig. 3, said openings being designed to-receive coupling-y pins or members 11,

which also serve asa means for fastening the -ends ofthe transverse connecting-wires or `tie-rods 12.

The wires or tie-rods 12 temporarily retain the lower ends ofthe walls 5 and 6 in engagement With the adjacent faces of the molded `-Wall 13 during the formation of the latter and until the cement, concrete, or-other Ina.-

terial sets or hardens, when the wires are' cut or severed close to the wall to permit the removal of the mold-sections, and said wires left embedded in the cement so as to rein s force and strengthen the wall.

The side walls of the several mold-sections are secured in spaced relation to each other by means of a transverse channel-bar 14, having a series of spaced openings 15 formed in one end thereof and provided fat its opposite end with a depending ivoted clamping member 16. The free en of the clamping member 16 is designed to bear against the angle-bars 7 of the mold-sections, while its opposite end is provided with a laterallyfprojecting head 17, which extends a shortdising-wires fastened to the heads of the pins, -as

v dows of the building, the outer wall 6 Aof the vthe pins 11, the cement, concrete, or other tance alcove the bar i4 to .permit the insertion of a loclringwedge or key 18. Slidably' mounted between ,the depending ilanges 19 ofthe bar 14 is a movable clamping member 20, adapte'd'to engage the angle-bars on the inner walls ofthe mold-sections, said clamping member being adjustable longitudinally of the bar 14 to ermit the formation of walls of diii'e'rent thicknesses and securely locked iii-adjusted position by a lbolt or similar `fastening device 21, passing'through one of the openings in the bar-14 and engaging a corresponding opening 22 in the angular extension -23 of said clamping member, as shown. In ractice the lower mold-section is irst place in position, with-the pivoted ends of the sliding clam ing members engaging the angie-irons 7, a er .which 'the wires 12 are stretched across the top .of the mold` and the ends thereotcoiled or :otherwise fastened to plaster material being subsequently shoveled or otherwise introduced between the' walls of the mold and thoroughly tamped.4 The upper mold-section is then placed uponthe lower section and the ends ofthe connectbest shown in Fig. 3 of the drawings. After the cement in the lower mold-section has set or hardened the iiexible wiresconnecting the lower ends of the side walls are cut or severed close to the surface of the cement, which permits the ready detachment of said lower section, the Wires being left embedded in the wall, thereby reinforcing and strengthening the latter and permitting the continuous operation oiithe mold during the formation of said Wall.

'In some cases the walls may be formed with vertical iiues or air-.chambers 24 by' p0- sitioning suitable core members 25 between the side walls of the mold-sections and elevating or drawing said cores upwardly as the hei ht of the wall increases.

lgn Fig. 4 of the drawings there is illustrated a section of a mold for constructing that portion of the wall adjacent to the winmold being formed with an auxiliary moldsection 27 forforming the window-sill. In this case a wooden nailin -block 28 is inserted between the side wal of the mold, to which maybe secured the window-casing 29, there being also a pair of core members 30, carried by a 4metal plate 31, positioned between-said side walls, for `forming suitable openings for the reception of the sashweights of the Window.

From the foregoing .description it willbe seen that there is provided an extremely simple and inexpensive device admirably adaptd for the attainment of the ends in view.

pins, said rods being adapted to be severed 1 and left embedded in the concrete when the mold-sections are removed.

2. A mold comprising a plurality of moldsections, a bar extending transversely across the top of said sections, a depending clamping member slidably mounted on the bar at one end thereof, a clampin member pivoted to the opposite end of thegbar and provided withv a laterally-extending head, and a locking-key adapted to engage said head and bar, respectively, for forcing the clamping memmold-sections.-

3. A mold consisting of a plurality of s uperposed mold-sectionseach comprising an outer and an inner wall provided with longitudinal reinforcing-'bars adapted to engage the reinforcing-bars of adjacent sections, a perforated barextending transversely across the upper mold-sectionsfa depending clamping member slidabl e end thereof an adapted to engage the reinbers into engagement with the adjacent' mounted on the bar at one Y p -9'5' forcing-bar on one of the walls of the adja-.

4. A mol for concrete-.constructions comprising a-plurality of superposed mold-sections each provided with -perforated;` longitu-y dinally-disposed angie-ironsf. adaptedto-qengage the angle-irons of ad'ac'ent ,mold-sec? tions, removable pins seate in saidA perforat1ons and servln to alineadjacent mold-sec- IIO.

tions, and iiexi le tie-rods connecting the"A Y mold-sections and havin fastened to said pins, said rods being adapted to be severed and left embedded -in the concrete when the mold-sections are detached.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in the presence of two witnesses.
