To all whom it may concern: w
Be it known that I, MILTON DANA Mpm RILL, a citizen of the United States, resldmg at Was'hingtom-inthe District of: Columbia,
have invented certain new and useful Improvements in Sectional Molds for Concrete Construction; and I do declare the following to be a full, clear, and exact description of the invention, such as will-enable'others skilled in the art .to which it appertalns to make and use the same, reference 'bemg had to the accompanying drawings, and to the letters and figures of reference marked party of this speci- My intention relates to concrete construc-v tion of buildings, in which reinforcing elements may be employed, and has reference more particularly to the elements employed for molding the concrete and which may be designated as a sectional mold for concrete construction.
The invention has sections of the mold are moved from one position to another as the construction-of the wall progresses; also to provide improved features by which the sections of the mold are secured one to the other; also to provide improved features in the formation and-in,
the manner of securing in place spacing blocks or spools by which the sides of the mold are held in proper relation to each other also in features of formation of the spacing spools or block by which the spool or block is caused to hold in position rein forcing elements while at the same time properly spacing the sections of the mold one from the other; also in features of construction of the mold by which may be facilitated the construction of the side walls together with the ceilings orfioors of the.
I for its object to provide improved features of construction by-which .to afford easier access to the of the mold and the spacing spools or'blocks and the reinforcing elements in relation to each other; Fig. 2 is a perspective, on an enlarged scale, of portions of the mold plates and a spacing spool or block, together with means for locking the several parts in osition; Fig. 3 is a perspective, on an enarged scale, of a portion of two adjoining plates of. the mold, showing the manner of locking, them together, together with provisions for connection of the red by which 35 one plate may be hinged to another plate for shifting the plates from "one position to another in the progress of construction; Fig. 4 is a perspective view, with portions broken away, showing one of the rods for hinging one plate to another; Fig. 5 is a perspective view, of'one of the mold plates for forming the inside corner of a wall; Fig. 6 is a permold; Fig. 7 is a perspective of one of the sideplates of the mold for forming the outside corner of the wall; Fig. 8 is a perspective' of one of the bars for supporting the spacing spool or block in being broken away.
spective of one of the side plates of the position, the bar Inthe drawings the numeral 1 designates metal side plates and metal inside corner plates, while 3 indicates the metal outside corner plate of the sectional mold, which several plates are formed with out-turned flanges 5 which are formed at suitable intervals with openings 6 for the passage of means for locking the plates together at desired points. The several plates at their corners are formed with a cut-away portion 7 so that at each corner where four of the plates come together there will be formed an opening for the passage of a bar 8 which -will support in position a block or spool to space apart opposite sides of the mold, and
at such points. the out-turned flanges 5 are cut-away on an incline as illustrated so as arts at-such points.- The plates constituting the side walls are spaced apart by blocks or spools 9 which are preferably made of concrete and are held in position hythe bars 8 which pass through a central opening in the spool and are sustained by locking keys 10 to which are tapered or wedge shaped and formed with a shouhl'or 11 to facilitate their witlnlrawal from the bars 8 and which bear against the flanges of the side plates as 2 1,o14,eso
preferablydiagonally disposed so that the keys will-exert a strong drawing action when driveninto place so as to more tightly drawand hold together the plates and the spacing spool to the plates. Each bar is also preferably formed at one end with an out-turned enter the spool.
support for the reinforcing elements WhlCh' lip 13 which will bear against the inside of 'the spool whenthe keys a e driven into place so as to enable a better rawing action ,to beobtained by the keys, the opening in the spool for the passage of the bar A being enlarged atthe end where the lip 13 will The spool also serves as a ma consist'of' horizontally disposed metal ro s 14 and vertically disposed metal rods 15, said rods being secured to the. spools by tie rods 16 which will be either molded in the spools or threaded through openings molded therein and will have their outer ends bent over on to the rods. Hand 15 as indicated in Figs. 1 and 2 of the drawing so as to secure the, reinforcing rods thereto.
The nieeting'flanges of the wall plates of the mold at other points than where the spools are located thereto will be connected together by U-shaped loops 16 formed with shouldered or tion passing through openings in the flanges, and a tapering or Wedge'shaped key 18 driven through the loop so as to tightly draw the flanges together so as to lock the plates in position. The wall plates of. a
ower section of the mold will beconnected with the wall plates of anupper section by means of rods or bars 19 WlllGll will be pivotally connected at their ends to flanges of I the upper and lower tier or sections of the wall plates so that'by such hinged connection when the lower portion of the wall has sufiiciently set, a lower tier of plates may be -swung from their position into a'higher position above an 11 plates and broug t into position so as to rest upon a tier or section of plates immediately next below, trateddn'Fig. 1 of the drawing which shows one tier of platesin the operation of being adjusted into'positi on above a lower tier of plates upon which they will rest and to which they will be locked. Inthus shifting one tier of plates from a lower to a higher position the tier of plates from which they have been unlocked and upon which they will rest will not be disturbed in position for the reason that the upper and lower tiers of plates are .locked together at the points where the spools are located by means of the keys 10 one of whichlies above the flange of one tier of plates the other beneath the flange of the lower tierof plates, so that passed through the parts together and in position;
T-heads 17, the looped pord per tier or section of the.
as for instance as illuswhen the keys beneath the flanges of the lower tier of plates are removed said plates "will be left free to be elevated to the posi tion illustrated in Fig. 1 without disturbing the tier of plates locked into positionat the points of location of the spools by the keys which bear against the top of the flanges to that tier of plates aswill be obvious from an inspection of Fig. 1 of the drawing. It will thus be observed that the feature of locking the plates together by the keys bearing against opposite bases of the flanges-is an important feature for this purpose. 7
At the points where the bars or rods 19 are pivotally hinged to the flanges of the two tiers of wall plates, the locking means for the plates consist of U-shaped loops 20 formed with shouldered or T-shaped heads 21 from one of which extends a lip or flange 22 to which the end of the -rod or bar 19 will be connected by a pivot bolt 23. The
U-shaped port-ion of the-loop 20 will pass through openings in the flanges of the wall plates ands/wedge shaped key 24 will be same so as to lock the For the urposeof'fo'rming cove inside corners to t e walls the inside corner plates of the mold are bent or curved in cross section as indicated 'in Figs. 1 and 5 of the rawing,
and to form angular corners onthe outside of the wall the outer corner 'plates of the mold are angular as illustrated in Figs. 1 and-7 ofthe drawing. Said plates are oth'erwiseiormed andheld in'position like the other wall plates of the mold. For
the purpose of formin cove lines where the walls and ceilings of-t with each other, bent or curved wall plates such as illustrated in Fig. 5 and designated by the numeral 2 are placed, 'and these curved wall plates flanges and ke s to joining wall p ates in the same manner as the vertically disposed wall plates secured one to the other. The wall plates ofthe e structure intersect i are; secured by their the flanges of the ad-- moldjor forming the ceilings or, floors are formed the same as the wall plates of the I mold for forming vertical walls of the struc plates of the mold are ture but such wall disposed. horizontally instead of vertically as illustrated in Fig. 1 of the drawing, and
these plates may or may not be connected together in tiers by hinged bars 19 as,de scribed. The spacing spools for'blocks; are disposedat the ,corners of the mold wall plates same as in the moldin of the vertical walls except that for the;- orizontal construction the spools will stand vertically instead of horizontally as illustrated in Fig. 3
1 of the drawing, and for the, purpose of affording temporary supports'for the horizontally disposed wall plates of the mold I wooden posts -25 are disposed at, appropriate points, for instance at the points where the .vertically disposed spacing spools will occur so that said spools and the lower wall plates of the mold at such points will be tempo-,
rarily supported by these-posts. In such cases the bars 8 which pass through the" spools may at their lower ends terminate within or on the level of the lower face of the spools so that the spools and plates may rest'squarely on the top of the. posts 25. This is made possible by reason of the pres ence of the out-turned lip 13 to the bar 8 which as previously stated will bear against the inside of the spool. ln molding the horizontal or floor portion of the structure elements consisting of the lips 14 and 15' are applied and attached in the, same man ner that described tor the vertical walls except that they extend horizontally instead of vertically, as illustrated in Fig. 1 of the drawing. I
It will be observed that whether the sectional mold be employed for either the vertical or the horizontally disposed walls of the structure, the constructimi ot' the parts of the molds are the same and their mode of application practically the same, the one diiference being in the horizontal or vertical disposition of the side wall plates of the mold.
By constructing and applying the parts as described I. provide a very simple construction which possesses strength in its several parts and which is capable of application with ease and expeditimnand make it possible to readily shift the wall plates ofthe same from one position toanother in the progress of the construction.
' I have described with particularity the' preferred details of construction and arrangement of the several parts but it is obvious that changes can be made in specific details of the several parts without departing from the spirit of the invention and from its scope as expressed in the appended claims.
