Application September 14, 1950, Serial No. 184,863

8 Claims.

The invention relates to an improved system of making split concrete block with natural broken faces for use as bricks, lintels, sills, slats and coping and in particular a pair of holders for gripping opposite sides of a green block ejected from a form and separating the sides each of which, as an illustration, forms one half of the block, by positioning on inverted V-shaped rails with a plane through the longitudinal center of the block positioned through the vertexes of the rails whereby with downward pressure upon the holders lips on the inner edges thereof break the block forming two substantially similar sections.

The purpose of thi invention is to provide means for gripping and breaking elongated concrete blocks or slabs whereby the surface material of both halves of the block is encased during the break-age operation to prevent chipping the corners of edges thereof.

Various methods have been provided for providing broken or stone faces on concrete blocks but where the blocks are broken after the con crete is hard a broken section shows chisel or drill marks and the breaking face is, sometimes, too irregular for use. Where the blocks are broken while the concrete is still green the sections crack and break to such an extent that the loss is comparatively high. With this thought in mind this invention contemplates a method of breaking concrete block longitudinally wherein the two halves of a block are gripped between holders whereby the material is supported continuously from the time it leaves the form until it is placed in a rack.

The object of this invention is, therefore, to

provide means for breaking concrete blocks longitudinally while the material is green in which the sections are supported to prevent cracking and breaking thereof.

Another object of the invention is to provide a holder for gripping sections of concrete blocks for breaking, which is adjustable to blocks of different sizes.

Another object of the invention is to provide holders and supports for breaking concrete blocks longitudinally into sections wherein each section may be positioned with the broken side up for finishing.

A further object of the invention is to provide holders for breaking green concrete blocks longitudinally into sections wherein the section are supported continuously around the peripheral surfaces thereof, which are of a simple and economical construction.

, the concrete blocks of my copending application With these and other objects and advantages in view the'invention embodies a pair of holders including fiat elongated panels having li s on the inner edges and flanges on the outer edges,

plates with knobs on the outer surfaces hinged to the ends of the elongated panels, springs urging the plates against the ends of a block section upon which the elongated panel is positioned and blocks or rails having V-shaped upper surfaces upon which hinged pallets with the blocks carried thereby are positioned.

Other features and advantages of the invention will appear from the following description taken in connection with the drawings wherein:

Figure 1 is a side elevational view showing part of a concrete block forming machine with the side walls of a mold positioned on the machine shown in section and with a block positionedon a 20 pallet extended upwardly above the mold.

Figure 2 is an end elevational view taken at a right angle to that shown in Fig. 1 also showing a block of material ejected from the mold or form and illustrating a holder positioned upon the block of material.

Figure 3 is a side elevational view similar to that shown in Fig. 1 showing the two sections of a block separated and positioned upon the V- shaped upper surface of a rail.

Figure 4 is a cross section on an enlarged scale illustrating two separated sections or halves of a block showing the rough surfaces formed by breaking the two sections apart.

Figure 5 is a cross section through the hinged pallet showing the parts extended straight outwardly.

Figure 6 is a plan view of the pallet shown in Fig. 5 with parts broken away.

Referring now to the drawings wherein like reference characters denote corresponding parts which is illustrated as positioned upon a vibrating plate 21 of a machine having a frame 28.

This invention provides means for breaking with the Serial No. 138,433.

The inner edges of the panels I!) and I5 are provided with continuous lips 29 and 39 that are pressed downwardly into the material of the 53 block forming a groove 3|, as shown in Fig. l and the outer edges are provided with centrally disposed flanges 32 and 33. The inner edges of the end plates of the holder are also provided with lips similar to the lips 29 and 36, the plates I and I2 having lips 34 and 35 on the inner edges and the plates l6 and I1 having similar lips 36 and 31. The lips on the end plates form vertically disposed grooves 38 in the ends of the blocks, and with the lips slightly inclined the grooves in both the ends and upper and lower surfaces will be V-shaped.

The end plates II and I2 of the panel I l are resiliently held against the ends of the blocks by springs 39 and 40, respectively, the springs being positioned between the upwardly extended legs 4| and 42 of the hinges I3 and I4, respectively and angles 43 and 44 mounted on thepanels. The angles 43 and 44 are provided with studs 45 and 46 for locating the ends of the springs and similar studs 41 and 48, respectively are provided on the legs 4| and 42 of the hinges. The plates II and I2 are provided with knobs 4S and. 50 by which. the holders are gripped by both hands of an operator as they are placed in position upon the upper surface of a block and the holders are also held by these knobs as the two half sections of the block are separated with the pallet sections 20 and 2| positioned upon the inclined surfaces forming the upper edges of the rails 24 and 25. Each of the end plates is provided with a series of bolt holes, as indicated by the numeral 5| for receiving bolts r screws by which the end plates are attached to the legs 4| and 42 of the hinges whereby the position of the plates may be adjusted to compensate for blocks of different dimensions.

The knobs, springs, and mounting means of the springs, of the holders l are similar to corresponding-parts of the holder I2 and for this reason the above description is not repeated.

The inner edges of the sections and 2| of the hinged pallet are provided with strips 52 and 53 having beveled u per edges which, as illustrated in Fig. 4 overlap the inner edges of the sections of the slots whereby continuous holding elements are provided around the peripheral surface of the block and these elements form a continuous groove on the dividing line of the block. When the block is placed upon the upper sloping surfaces of the rails 24 and with the inner edges of the sections 20 and 2| of the hinged pallet positioned on the vertexes of the rails, the small flanges or lips pull against the continuous outer edges of the sections. With an operator gripping the knobs of the end plates of both of the holders a slight outward or separating pressure is applied as the block of green material is positioned upon the rails 24 and 25. This causes a substantially even break but with the exposed surface of the block or brick rough.

The concrete block splitting or breaking device of this invention may be used with concrete blocks formed with any suitable type of mold or form or on machines of different types and design. The machine shown in the drawingsof the application is for the purpose of illustration only and, as illustrated in Figs. 1 and 3 concrete blocks are formed in a mold 26 which is mounted on a vibrator plate 21 suspended above a frame 28 by a spring 54 and 55, and after the blocks are formed they are ejected by blocks 56 on vertically actuating rods 51, the lower ends of which are provided with rollers 58. The plate 21 may be vibrated by any suitable means and the rod 51 may also be elevated by suitable means.

After the blocks are formed they are ejected by the blocks 56 with which they are held above a form 26, as shown in Fig. 1 until the rails 24 and 25 are positioned under the pallet and the holders including the panels HI and I5 are positioned upon theupper surface of the block. With the holders in position the ejecting blocks and rods are lowered and by pressing downwardly on the holders, with the holders gripped by the knobs 49 and 5B the blocks readily break in half forming two sections 59 and 60. These sections are then removed and placed upon tables or other dryingmeans.

Before filling the form with the'material of the blocks the. inner pallets I8 and I9 are positioned upon the pallets 20 and 2|, as shown in Fig. 4, to facil-itateremoving the sections of the block from the hinged pallet.

It will also be understood that inner pallets may be vertically positioned in the form and held by the flanges 32 and 33 whereby block sections of different'thicknesses may be formed and with the pallets held by the flanges 32 and 33 the-sections-of the blocks-may be .removed from the hinged pallet and positioned with the rough face extended upwardly whereby the rough or broken face may be worked over for finishing or coloring.

It will also be understood that the roughened faces of the block sections may be formed of different colors and also that a coloring pigment may be used in the material from which the blocks are formed whereby the blocks .may be provided in different colors.

It will also be understood that the partitions may be used in the form as in my co -pending application with the Serial No. 138,433, filed January 13, 1950, whereby the sections. may be dividedto form blocks of different sizes.

It will also be understood that modifications may be made in the designand arrangement of the parts without departing from the spirit of the invention.
