Specification of Letters Patent.
Patented March 6, 1906.
Application filed May 26, 1905- Serial No. 262,511.
To all whom it may concern:
Be it known that I, HAROLD A. Low, a citizen of the United States, residing at Lake 'corners of walls; third, for making blocks with central vertical openings and providing their front faces with water-tables; fourth, for making blocks of reduced length in the same mold.
My invention consists in the construction, arrangement, and combination of parts, as hereinafter set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which Figure 1 is a top view of the mold, showing all the parts combined as required for filling in concrete to produce an elongated block with a tapering vertical central andopen passage in its ends communicating with the central opening. Fig. 2 is a central longitudinal view of Fig. 1 and shows how the tapering core in the center is held in place by movable supports extended through apertures in the ends of the mold. Fig. 3 is a top view that shows the mold transformed as required for making blocks for corners of walls with the front and one end face smooth and solid. Fig. 4 is a transverse sectional view that shows an auxiliary bottom in the mold for making blocks with central vertical openings and providing their front faces with Watertables. Fig. 5 is a top view that shows how to make blocks of reduced length in the same mold. Fig. 6 is a longitudinal central sectional View of Fig. 5 and shows the manner of supporting one end piece of the mold in the central portion thereof in a vertical position.
The numeral 10 designates the bottom flat board, and 12 and 13 the movable sides of the mold. They may vary in width and height and length, as required for making blocks of different size. Cleats 15 are fixed to the inside faces and end portions of the movable SIClGS 12 for supporting the movable ends 16 1n vertical positions, and cleats 17 are preferably fixed to their outside faces, as shown in Fig. 1. Strips of molding 18 are fixed on the top of the bottom 10 to engage theinside faces and lower portions of the sides 12 and 13, as shown in Fig. 4, to produce beveled edges of the blocks at the edges of their front faces produced on the bottom of the mold. Corresponding strips of molding 19 are fixed to the inside faces and lower portions of the end 16 to produce beveled edges at the ends of the blocks. By thus fixing the cleats 19 to the ends 16 the ends can be located at different points on the bottom 10, as required to produce blocks of different lengths in the same mold.
To aid in supporting the sides 12 and 13 in vertical positions, staples 21 are fixed in their outsides and pins 22 are passed down through the staples into apertures in the bottom 10, as shown in Fig. 1, or in any suitable way. The ends 16 have central apertures, through which core supports 22 are extended, as clearly shown in Fig. 2, to be detachably connected with a tapering core 23, preferably hollow, by means of pins 24 or in any suitable way, as required to retain the core suspended in the mold and its ends in contact with the inside faces of the sides 12 and 13. At the sides of the apertures in the movable ends 16 and on their inside faces are fixed cores 25, that produce corresponding recesses in the ends of the blocks to admit the fingers of persons, as required to facilitate manually lifting and moving the blocks.
To lockthe movable sides 12 and 13 against the movable ends 16, bars 26, having crosspieces 27 fixed to their ends and under sides, are placed across the mold so the cross-pieces will engage the outside faces of the sides.
By flushing concrete into the mold when the movable parts are in position, as shown in Figs. 1 and 2, long blocks are produced with vertical central openings having cavities in their ends communicating with the central openings and recesses or handholds in their ends.
To produce a block adapted for corners of walls, the mold is transformed by using a smaller core 23 and placing a metal plate 28 in one end and supporting it by movable pins 29, as shown in Fig. 3, or in any suitable way, as required for producing a solid smoothfaced end.
To produce blocks having water-tables at the top edges of their front faces, an auxiliary bottom 30 is placed in the mold and a piece of fixed on their inside faces to grooves in the ends of the b ocks in place of molding 31 on top of it, asshown in Fig. 4, and the top face of the auxiliary bottom is preferably grooved, as required to produce a corrugated front face on the bloc i.
To produce short blocks, the mold is transformed, as shown in Figs. 5 and 6, by placing one of the ends 16 on the central portion of the bottom and supporting it there by a board 32 in the bottom of the mold and a board 33 in the top of the mold and provided with cleats 34, fixed on its top to extend over and rest on the top edges of the sides 12 and 13, as shown in Fig. 6. The outer ends of the boards 32 and 33 engage the cleats 15 on the sides 10 and 12, as required to retain the movable end 16 in the center of the mold perpendicular.
It is obvious that by thus transforming the mold the four different kinds of blocks are readily and advantageously produced by filling the molds with concrete and allowing it to dry sufficiently before separating the movable parts of the mold away from the blocks.
In Figs. 2 and 6 the cores are removed from the ends 16 and half-round strips roduce vertical recesses for handholds.
Having thus set forth the purpose of my invention and its construction and manner of use, the practical thereof will be readily understood by persons familiar with the art to which it pertains.
What I claim as new, and desire to secure by Letters Patent, is-
