To all whom 'it may concern: form air spaces in the Be it known that I, Goi'rnan'r Tnnnnnfr, a citizen of the United States, and'a resident of Pittseld, in the county of Berkshire and l cores which serve to completed wall and raising the mold sections and the c ore step by step as the Wall is built State of- Massachusetts, have invented a new l ln the specific construction illustrated, and Improved Mold for Concrete-Wall Con- I each mold section 10 is formed ofav sub.- struction, of which the following is a full, stantially rectangular frame l1 of Wood or clear, and 'exact description.

stay bars l1il and having a face plate 12 Se- This invention relates to certain improvements in molds :tor concrete Wall construction, and more particularly to means for l concrete while the latter is hardening. This face plate is referably of metal and may be either smootii or 'embossed surface of any suitable form to give the nished concrete `wall appearance, as illustrated at 12 in Fig. 8. For supporting and raising the sections, I provide a plurality of vertical standards 13' adapted to be embedded Within the wall andextending upright therein intermediate the mold sections. Each upright is somewhat tapered in cross section, as is clearly illus trated in-Fi s. 4 and 7, and is located adjaf cent one of t e cores, whereby after the wall- "has been completed to the desired height and the core removed, the upright may be moved .laterally into the passage formed by the core and then may be removed entirely from the wall. As illustrated, each standard is provided with oppositely -disposed perforated metal face plates 14, which are engaged by the raising mechanism and serve to protect the wooden body portion of the upright. As shown, the supports for the mold sections comprise a pluia ity ofsubstantially vertical rods 15, each in rigid engagement with the upper and lower sides of the' frames of the mold sections and each end bent inward to a point adjacent one of the uprights. The two rods` are pivoted together at this-point*` and connected tdthe raising mechenisin which surrounds the upholding the mold sections in engagement with the Walls and for raising them step by step as the Wall is built up. My invention also involves certain construction in collapsible cores to be used in connection with said molds and coperating with the support for the'- mold sections to permit the'. latter. l l

e invention consists in certain features of construction and combinationsv of parts,

the removal of after and claims. l

Refereneeds to'be had to the accompanying drawings, fornuinpf a part of this specifi particularly pointed out in the ence indicate corresponding parts in all the ligures, and in Whichn Figure 1 is a top plan view of a wall in process of construction and illustrating one embodiment of my invention; Fig. 2 is a side'elevation of one corner of the structure shown in Fig. 1, and on an enlarged scale; Fi, 3 is a transverse section showing the nio d and core after having been raised for the construction of a second section of the Wall, said vieiv being taken on the line 3MB of Fig. 4; Fig. e is a top plan view showing the mold core and raising mechanism on an enlarged scale; Fig. 5 is an inverted plan view of thev core; Fig. 6 is a side elevation partly' `in section, showing the mold-raising i right and serves for lifting the latter when a is a plan view of a corner section of the wall has been completed. The of the wall construction; and Fig. 8 is a rods'ere connected together ata point adjat'ransverse section through a modified form "cent the upper edge ot the mold sections, and d i the connecting mechanism is soconstiucted Wall a roiighened vor rectangular surface. ,l :is to also serve as ineens for spreading the In my improved method of coiistructingl sections apart. This connecting mechanism provide oppositely-disposed preferably comprises a cross bar lo having mold sections spaced apart to the desired one'eud pivoted to one of'ihe rods 15, and distance and adapted to support and hold having the opposite cnd'pivoted to a lever the concrete in lace While it is hardening to 17, one end of which is pivoted to the tippeform a Wall. l ithin the mold are provided sitely-disposed rod l5. The bar 16 is pivotmeans are provided for the desired cured thereto and adapted to support the i or present a gured uneven'- having its upper ed to the lever at a short distance from the pivotal support of the latter, and by .the movement ci? thellever the sections may be brought toward each other to the desired position or may be spaced apart and separate from the completed wall. lilith the lever extending out Yardly, illustrated in Figs. 3 and d, the sections are held rigid in respect to each other, but when the lever is raised, each of the two sections is inovcdi'orward and out ot' engagement with the wall the sections hein'g supported by the vrods 1, the upnrr ends of which are connected to the corresponding upright 13. As the ujper ends of the rods 15 arc connected together and the har l'co'nnects them intermediate their ends, it is evident that the lower ends are also held rigid in respect to each other, but to prevent any possible bending of the parts and to hold the lower portion lof the mold sections in lirm engagement with the portion ot the wall just completed, l may, it' desired, provide a tie-bar 1S having an operating handle 18 at one end thereof, and having the opposite end threadedi'or the rcception of a nut in engagement with the 0pnosite mold section. By tightening this tie'- bar, the 'lower ends of the section are positively prevented from spreading apart from the pressure of the concrete.

For raising the mold sections, I provide mechanism in engagement with the upper ends of the rods 15 and with the uprights, and having suitable handles for operating the saine, whereby the sections may be. read-- ily raised irresliective of the weight thereof. As illustrated, this mechanism comprised a rectangular' frame 19 having gripping arms 2O and 21, pivotally connected to the opposite ends thereof, each of the arms inelosing the upright and engaging therewith at the side opposite to its pivotal support. Each arm is provided with an inwarally-directed tooth or projection adapted tol enter one of the pertorations of the face plates 14 on the uprights, and the upper ends ol' the two arms are connected together by a suitable coil spring Q3. rllhe 'trame 1S) is provided with handles and 525 extending cui wardly therei'rci'n in opposite directions, and by .means ot these handles the .traine may be rocked to cause the gripping arins to engage at successively higher points on the opposite sidesot the upright, and thuslit't the entire raising mechanism and the mold sections connected thereto. The traine 15) pio vided with depending plate Qt? at one sido thereoi", and to thisplate are pivotally con-- nected the two oppositely-disposed rods 1. The plate is provided with suitable, lian; is QT engaging with the opposite sides ot t ie upright to hold the plate in a .saibstantially 'vertical position and prevent side movement thereof in respect to the upright.

siegel In the operation of the raising mechanism, the teeth of the two gripping arms engage in recesses in opposite sides of an up right, and by raising one of the handles,' as, for instance, the handle 2li, the gripping arm 21' is raised along the side of the upright to the position illustrated in dotted lines. During this upward movement of the arm 21 and handle Q41-, the entire weightoil thefafall sections is supported by the arm The handle 25 is then raised and the tooth of the arm 21 engages with the upright and the entire wall section is raised and the gripping arm 22 is also raised to a higher point on the side of the upright. Before raising the mold sections, the lower tie-rod 18 is lirst removed and the lever 17 raised to spread the mold sections apart. When the mold sections have been raised te the desired height, they are againbrought toward each other by the lowering oi the lever 17 and the lower ends are firmly bound together by 1the insertion oi the tie-rod, 18. rllhe small transverse opening left in the wall by the removal of the tie-rod 18 may readily be filled with concrete from both ends thereof to conceal the same from view.

In connection with the mold sections and raising mechanism above describethl preferably provide a plurality of cores serving for the formation of' air spaces within the completed wall. he cores may be of any desired shape in cross section, out are preterably formed with rounded ends and straight sides, as illustrated in the drawings.

The top of each core is formed oit a plate 'QS oit the desiredshape, -and the sides and ends of the core are preferably formed of vsheet metal walls 29 similar to the sheet metal walls of the mold sections. At the bottom of each core, I preferably provide blocks 30, to hold the cores in the desired position, and between the opposite side walls 29 means is provided for drawing these walls together and partially eellapsing theI core to facilitate the removal thereof from the wall after the concrete has hardened. As illustrated, .this collapsing mea'ns includes a rod 3l extending vertically through the central portion ot' the core, and having a plate rigidly secured to thedower end thereof. This plate is provided-with two crm slots 33 for the reception of pins 3i carried by the mold sections at their lower ends. By rotating the rod 31 the pins are caused to tra-vel inwardly or outwardly' due to the curvature of the slots, and the slots are so 't'ornied that the parts will remain ineither the extended or the collapsed position. By drawing the side walls of the core together, illustrated in dotted line in Fig. 5, the width of the core is redu'ced to a mat .rial extent and the curved end portions of the core are also brought `somewhat,nearer together: With the core thus reduced iii cross section, it may be readily removedfroni the hardened concrete about the saine and maybe readily raised with the mold sec-` 6 tions. 'The upper end of the rod 31 is pret- I erably rigidly connected to a transverse supporting bai'- 35, which enga es lwith the up r' siirface of the' opposite -y disposed' mo d sections for supporting the core, and is '10 preferahlfyof spring metal to permit of the raisingo the ends of the bar out of engagement with the mold sections to rotate the berend the rod 31 and to collapse the core.

Where it is desired to form a corner in the '1 5 wall, I provide means for rigidly securing together the outer mold sections which meet at theangle, and provide means to facilitate 1 the uniting-1 of the inner mold sections at the inner side of thewall. One of the outer moldl sections nt the corner is provided with v perforated lugs 36 at the upper and the ower edges thereof, and the other mold section coperating" therewith to form the corner is provided with locking mechanism V adapted for en agement with these lugs. As

illustrated in ig. 2, this locking mechanism comprises two pivoted arms 37 adjacent the upper andv the lower sides of the/mold sections and each having an outwardly-ex A tending dog or projection adapted for engagment in the perforation of the corre- .sponding rejection 36 of the other mold section. o each of the arms is pivotelly connected a link 38, and the inner ends of, '85 the two links are connected to an oscillating t member 39. By oscillating the member 39, the linkseare drawn inward or forced out- WardA to iemove vthe arms from engagement vwith the lugs or force them into such en- 40 gagementto lock the mold sections together Ior to separate the seine. At the inner corner of tlie'wall, erich of the inner mold sections is formed lof such a' length that the sections do not ineet'when the mold is in place for the reception of the concrete, but the gap between the two endsv is closed by a verticall -disposed angle-iron 40, as illustrated in iigs. l and To facilitate the removal of the uprights after the wall has been completed to a consi'derable height, -l provide certain of the cores with ends of s slightly greater Width than the width of the uprights, and 1n engagement with the sides of said upri hts, as

illustrated more clearly iii Fig. 7. W en the wall hns been huilt up to the height of the upright, the cores adjacent said u rights are entirely removed, sind due to tie tapered forni of the uprights, they may be readily movedlnterully into the hollow space in the wall which was formed by the core. The upright mayy then be raised out 'of the wall and supported on to thereof to serve for the further raising o the mold sections.
