MULTIPLE CONCRETE-BLOCK MOLD.
medication of Letters Patent.
Patented N 0v. 19, 1918.
To all whom it may concern:
Be it known that I, WILLIs L. CUTLER a citizen of the United States, residing at Legrand, in the county of Marshall and. State of Iowa, have invented certain new and useful Improvements in Multiple Concrete- Block Molds, of which the following is a specification.
,This invention relates to multiple concrete block mold and has for its principal objects to produce a mold in which a plurality of concrete blocks can be formed by a single pouring; to produce a mold that can be easily set up and taken down; to produce a mold in which a two part 0011- orete block can be cast; to produce a concrete block forming mold which can be taken down before the blocks are completely dried without injury to the blocks; to produce a plural block mold which can be used a plurality of times; to produce a mold in which slush concrete blocks can be formed; to produce a multiple concrete block mold so organized that slush concrete when poured will flow to all parts thereof from asingle point of pouring; to provide a mold in which concrete blocks can be formed from slush concrete; to produce a mold in which concrete blocks can be formed which are made up of two parts tied together; to produce a mold for making wire spaced apart two part concrete blocks in quantities by a single operation; to provide a mold frame made up of a plurality of separate units; to produce a mold frame in which the units thereof are constructed so that communicating passageways are afforded between the various sections of the mold; to produce an extremely simple. mold that is inexpensive to manufacture, and, in general to produce a unitary concrete block mold of the class referred to.
Further objects not above referred to will appear from an examination of the specification and drawings.
In the accompanying drawings;
Figure 1, is a perspective view of the multiple concrete block mold, parts being broken away to more clearly show the interior.
Fig. 2. is a side elevation of one of the longitudinal units.
Fig. 3, is a sectional transverse elevation of two of the units.
Fig. 4, is a similar view to that shown in Fig.3 showing the division plate and wires in position.
ig. 5, is a perspective view of one of the blocks produced by the mold.
Fig. 6, is a plan view of one half of the mold.
Fig. 7 is a longitudinal section elevation showing the method of casting a corner block, and
Fig. 8, is a perspective view of a portion ofthe mold showing the corner block core in position.
Referring to the drawings the mold is provided with end plates 11 and 12 and side plates 13 and 14. The plates 11 and 12 have their upper and lower edges bent inwardly back upon themselves as shown at 15 so as to furnish added strength. The end plates 11 and 12 are also provided with a plurality of openings 16 and the'sicle plates 13 and 14 are each provided with a single opening 17 similar to opening 16, the function of these openings will hereafter appear.
The units shown at 18 in Fig. l and in detail in Fig. 2 are composed of two members, the upper one, 19 being U-shaped and inverted when in position, the lower one 21 being similar in outline but in normal U position. I
The end plates 11 and 12 are cut away as shown at 20 to furnish means for holding the ends of the units in position. Each upper member 19, five being shown in the present construction, has a pair of flanges 22. These flanges are bent slightly clownwardly out of horizontal position as shown in Figs. 3 and 4. Each lower member 21 has which are bent upwardly. The two U shaped members are permanently secured together by spacers 24: inserted between the sides of the U and riveted or otherwise secured therein. There is a plurality of these spacers throughout the length of; each unit 18, and the end ones have secured thereto a strap 26. This strap is bent so that its outer end lies in a horizontal plane and is provided with an opening 27. This outer end is adapted to project through openings 16 in the end plates 11 and 12. A wedge 28 is adapted to be inserted in the opening 27 thereby firmly securing each unit 18 in place and securely holding the end plates 11 and considerably shorter,
eas es 12 against out-ward movement. A similar locking device is used to secure the side plates 13 and 1 1 against movement. The only diiicrence being that the strap instead of being" short extends clear across from side to sideas at '29 and is positioned midway between the end plates 11 and 12. These end plates 11 and. 12 are provided at their ends with flanges 31 similar to flanges 15 to assist in holding the parts in position.
'lransversely of the mold are two rows of partitions, each row, in the present device, is composed of live partitions 32, Figs. 1 and 8. These partitions are each made up of two opposed U shape members 33 and 31. They are linked together and held in spaced apart relationship by spacers 86. Tn order to hold these partitions 32 in position the flanges and 23 of each U 19 and 21 are slotted as at 37. as thus positioned they are prevented from moving longitudinally by the members 19 and .21 and from sidewise movement by flanges and The end partitions have their outer edges held in slots in the flanges 38 of the side plates 13 and 1%.
The flanges of the U members 19 of the longitudinal units 18 are each provided with a series of openings or slots 39 in their outer edges. The end flanges 38 are also similarly furnished with openings 39. These openings 39 are designed to receive wires 11.
Referring now to Figs. 7 and 8 these views show the method of casting a corner block. The essential feature of this is a core 12 which is made up of a short side a3, a long side 1 1 and a base. Each side of this base is provided with slots l6 for the reception of wires a? similar to wires 11 and a corner wire :8. The partition 82 in this instance being solid so that the concrete cannot flow from the space between the core and the partition into the space beyond the partition The flange "22 of the member 19 being cut away as at 49 to permit the corner block to be cast with a slot, which would occur it this flange remained uncut. lie terring back to Fig. 1 and particularly the longitudinal units 18; on the upper surface of the two flanges 22 that face each other of the adjacent members 19, and between the wires 4C1, placed a division plate 51 as is shown in 1 and at. These plates are of a length equal to the distance between two partitions 32 and of a width equal to the distance between the wires 11 of opposite flange 22.
The method of procedure is as follows: After the mold has been set up and locked, as is apparent from the foregoing descrip tion, it is placed upon five pallets, one for each row of three blocks; slush concrete is now poured into the mold until it reaches the level of the top of the flanges 28, as
shown in Fig. 8. A scraping tool is now used to stroke oil or smooth the upper sur- 1 face of the concrete. It is of course understood that this concrete is still very soft. The next step is to place the wires 11 in the holes 39 and press them down into the soft concrete mass as clearly shown in Fig. 4; then the plates 51, one for each block, are set down upon the flanges and be tween opposite sets of wires 11. This leaves an air space 53 between the top of the lower half of the block and the plate 51. New concrete is poured into the upper half of the mold up to the tops of the Us 19 and 33, the plates 51 serving as the bottom of the upper half of the block. The excess material is now scraped off making the upper surface smooth. In strokingoil the upper surface of the lower hall of the block the openings through the units 18 and the partitions 32 serving as convenient means for getting rid of the excess material in any one section by permitting it to run into the next adjacent one.
When the mold has been completely filled, it is allowed to stand until the slush concrete has sulliciently hardened so that the blocks will retain their shape when standing alone. The pin 28 now remover. This permits the side plate and end plates to drop away from the remainder of the mold. After the two partitions in the first section of the mold have been removed, the pallet on which the three blocks of the first section rests is slid sidewise sufficiently to permit the next unit 18 to be removed. This process is continued until all the frame members of the mold have been separated from the blocks. During the time when the blocks are separated from the mold, and when completely dried so that they can be handled, the mold may be used for the next operation. The core 12 for the corner block of course, cannot be removed until the blocks can be handled as it must be downwardly.
Various modifications and changes may be made without departing from the scope of the invention as defined by the appended claims.
