. applicati@ inednugust 2o, 1925. seriai'no. 51,311T 'i This -invention `relates to improvement yin molds for concretefbuilding blocks. `My ob.- jectl is'fto make al mold or form` in which la single unit concrete block can be' easily made that will-lay a dry hollow wall.
Referring to the drawing Fig. zontal section through# a mold made inV accordance with my inventionV illustrating the form of building block produced therein,
and Fig. 2 is a perspective view of the,` core Y removed from the mold. e Y j The open top, box-shaped mold 5 has the sides 6 and 7 and the ends 8 and 9 hinged to the bottom thereof as indicated at 10to permit opening the mold to remove a block when made. The sides and ends are ar-y ranged to be held together by hooks or other suitable means at 11 when the mold is set up for use. A core 12 is placed in the mold and 2o suitably held in position by means of pins 13 in a manner Well known in the art, there being pref-erably at least one pin at each end of the core and also one on the ybottom thereof to lit openings provided therefor in the mold in the usual manner.
may also vbe provided for removing thecore from the mold after a block has been formed. The core, it will be noticed, is of irregular form. It is substantially as high as .thel mold with the top and bottom'surfaces substantially parallel and the side and end sur` faces as well, there being a slight taper from top to bottom to make it easy to withdraw from the mold. The core when placed in the mold is spaced equidistant from the sides in the manner shown, thusleaving an open space on each side of the core to-ill in the concrete indicated at 14;. The core has acavity or indentation 15 extending vertically across one face thereof which is cut deeper than half the width of the core. Thiscav-V ity results in the forming of a lug 16 on the tile produced on that side of the core. The
'Y other face of the core has cavities orV indentations -17 at opposite ends ofthe core to re sult in the forming of lugs-18 in the tile producedon this side ofthe core. Each of the cavities 17 is approximately half as Wide as the cavity 16 so that the lugs 18 are half as wide as the lug 16. The purpose in this is fully set forth in my copending application, Serial No. 32,312 filed May 23, 1925,
which application covers the concrete building block per se.
The core is alittle shorter than the mold.
` It is held in position s0 that eachv end `is Suitable means spaced .a shortfdistance from the end kof g `Lai-2,1810v mold as indicatedat 19. This space is so row lspaceallows iron tie rods. 2() to pass through it and around the ends of the core from the space on oneKV side into the space on the other-side. 1 Thinbar iron or wire ties are usedto bind the partsv of the'block together. Two or more single tie rods or a block should be united near the top andnear the bottom to hold it rigid for handling.
One detail of the core is changed to make an end block for a course in al Wall. One end of the core is removed as far as the 0E- set 17 leaving space for concrete, acrossthe end of the block between the core and the mold. The core is spaced and the iron tie vnarrow concrete does not fill it. "Thisnarv tiehaving two or moretransverse members should be used on each end of a block. 'A
Yas
used at the other end the sameas in making Y common blocks. Y
The block made in this vmold will have two rectangular tiles spaced apart and held parallel with each other. Each tile will have one or more concrete lugs on its inside face that extends toward the opposite tile more than half the distance between the two tiles. There will be a continuous air space'vertically through the block. The two parts or tiles will be united into a single unit by the Y iron rods across the ends of the block."
Then a course of blocks is laid in the wall the block in the course next above will be shifted a half block to lap or break joints. The lugs on the upper course will' overlap the lugs on the course below it and tie the walltogether. in a straight line in a wall because they are units, and the wall will be ready to plaster. Iclaim; Y
1. In a box shaped mold for concrete These blocks are easy to keepy building blocks open at the top, a removable i core that is narrower and shorter than the mold, having its sides substantially parallel with each other and with the sides of the mold and.V spaced equally from the'sides 0f the mold, one side of said core having a vertic-al cavity or indentation at its middle .i
more than half the thickness of the core extending from bottom to top and wide enough to form a concrete lug on the tile on that side of the concrete block.
2. In a mold for concrete building blocks,
' a removable core which divides the mold cavity longitudinally into two separate cavities to vform two aies for a building block, said y vg a i i 1,652,180
core being spaced slightly from the ends of the cavity so that tie rods may be passed around each end of the core to be imbedded at their ends in the two tiles `Whereb to connect the same and form a unitary b ook.
3. In a box-shaped mold for concrete building blocks open at the top, a removable core narrower and shorter than the mold having its sides substantially parallel with each other and with the sides of the mold and spaced equally from the sides of the mold, one side of said core having a vertical cavity or indentation at the middle thereof more than half the thickness ofthe core and extending from top to bottom thereof. to
form a `concrete lug on the tile on that side of the eoreftha other side of said coreV having vertical cavities or indentatidns at the ends of the core more than half the thickness of the core but approximately half as wide as the irst` mentioned cavity or indentation and extending from top to bottom 'of the core to form concrete lugs on the tile on that side of the core, the spaces between the ends of the i core and the adjacent Walls of the mold per mittingxthe passing of tie rods awross each end of the core to be embedded inV the' two t tiles to connect the same and form a. unitary block. i i i t In testimony whereof I have signed my name to thisspecilication.
