Patented Oct. 9, 1 951 MOLD FOR CONCRETE BLOCKS Ann THE LIKE Titus. Russell, Albion, Mich.
Application August 16, 1948. Serial No. 44,452
Claims. (Cl. 25-121) This invention relates to improvements inia mold for concrete blocks and'the like.
' The main objects of this invention are: "First; to provide a mold for concrete blocks: and .the like well adapted for making blocksrcomprising two spaced sections connected by tie: rods or spacers thereby providing blocks adapted for use in the erection of double walled structures.-
' Second, to provide a mold having these advantages which enables the rapid'production ofuniform blocks having smooth surfaces.
Third, to provide a mold having the advantages stated which is simple to assemble and economical in its parts and very durable and convenient to use.
Further objects relating to details and economies of the invention will appear from the description to follow. The invention is pointed out in the claims. v
A preferred embodiment of the invention is illustrated in the accompanying drawing, in which:
- Fig. 1 is a perspective view of a :mold embodying my invention, the top blocksection bottom being shown in position. a
' Fig. 2 is an enlarged transverse section on a line corresponding to line 25-2 of Fig. 1 with fragments of a block shown therein.
' Fig. 3 is a plan view with one of the mold 'walls swung to partially opened position to illustrate details of the connections for the walls. Fig. 4 is a perspective view of a block formed in the mold illustrated.
"Fig. 5 is a perspective view of one of the top 'blo'ck section bottom members.
Fig. 6 is a perspectiveview of a facing plate which may be used to produce the face design shown in Fig. 4. a
The embodiment of my invention illustrated comprises side walls I and 2 and end walls 33. The'end walls are formed with outwardly projecting flanges A on their vertical edges, the ends of the side walls being disposed in overlapping relation to these flanges.
The side and end walls are connected by the bolts 5 and 6 arranged through the side walls and the flanges overlapped thereby. Coil springs I are arranged on thebolts 5 so that the walls can be opened or spread with a tilting movement on the bolts as is indicated in Fig. 3.
The side wall 2 is provided witha slot 8 re- Av thumb nut V 9' is provided for the bolt 6. This enables the spreading of "the walls to permit the removal Of' the mold from a formed block by releasing the wall 2' openings l4 and i5 respectively. These are desirably of rectangular form.
by removal of the thumb nut. The springs are designed to have tension enough to keep the walls in erected molding position but I may also provide locking rods 16 having downturned ends H 'engageable over the 'upper edges of the side walls, desirably with the loops [2 thereof on the outer sides of the end walls.
l3 represents'a pallet or support on which the molds may be placed for the moldingoperation. The side and end walls define centrally elongated Theside and end'walls are 'providedwith internal ledge-like supports l6 and IT to receive the bottom members l8 for the top section of the block. These bottom members l8 have The flange-like members [9, also provide 'reinforcing means for the inner edges of the bottom members permitting the same to be fabricated from relatively light stock. These bottom members have slot-like openings 20 therein through which the tie rods 2| for the block sections 22 and 23 may be passed. The-mold side walls are provided with internal longitudinal ribs 24 which result in longitudinal mortar receiving grooves 25' in the edges of the block sections.
In the use of the mold it is placed upon a pallet, l3 or other suitable support and concrete or other material to be molded introduced to form the bottom section 22 of the block. The inner side of the section 22 may be struck ofi through the'op'enings in the walls 'orfromfthe top, the excess material being pushed out or then introduced above the bottom members 18 and imbeds the projecting ends of the tie rods.
This material is then struck oif and if it is desired to provide a face design, such as results in the transverse and longitudinal grooves 34 and 25, they may be conveniently formed by means of the board 26 having the transverse and longitudinal ribs 21' and 28. This serves to break up, the face to represent blocks of different sizes when laid in the wall. The grooves 25-, resulting-from the ribs 24 in the mold, provide mortar grooves or channels. 7
With' the material for themold sections suitably placed and after the material molded has sufliciently set to be self-sustaining'the mold can be quickly removed leaving the block supported by the pallet l 3 or other supporting surface. The terms bottom section and upper or top section of the block are used in reference to the mold and not as to the block as such.
It is contemplated that wheeled molding tables or benches may be advantageously employed to be moved to the molding station and from the molding station with a number of blocks thereon and the blocks left on the benches until set for handling or to be loaded into a truck or car for transportation. The mold is comparatively light in weight and is easily handled or manipulated.
I have illustrated and described my invention in a highly practical embodiment thereof. I have not attempted to illustrate or describe certain embodiments or adaptations of my invention which I contemplate as it is believed that this dsiclosure will enable those skilled in the art to embody or adapt my invention as may be desired.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
