To all w/wm, it may concern.-
Be it known that we, J OIIN ARTHUR BLAKE and JAY KENRICH, citizens of the United States, and residents of l/Volcott, in the county of IVhite and State of Indiana, have made certain new and useful Improvements in Concrete-Block Machines, of which the following is a specification.
This invention is an improvement in machines for use in making concrete buildingblocks; and the invention consists in certain novel constructions and combinations of parts, as will be hereinafter described and claimed.
In the drawings, Figure 1 is a top plan view of a machine embodying our invention. Fig. 2 is a detail side elevation of the mold box taken from the inner side thereof, the inner side section and the end sections being opened. Fig. 3 is a side elevation of a machine, partly in section; and Fig. 4 is an end elevation of the box, the sides and ends be ing open. Fig. 5 is a detail top plan View, partly in section, showing one of the moldboxes and the latch for securing the same in pressing position. Fig. 6 is a cross-sectional view of the bottom of the mold-box. Fig. 7 is a detail top plan view of a portion of the bottom of the mold-box, the platen being removed; and Fig. 8 is a detail side view of one of the dogs used for supporting the platen after the pressing operation.
In carrying out our invention we employ a revolving carrier for a series of mold-boxes, such carrier being mounted on a base A and comprising an upright shaft B, top beams B on said shaft B, and strut-braces B support ing the top beams B, roller-bearin s C being provided between the base I) of the shaft B and a bed-plate a on the base-beams A, and a tie rod D extending through the plate a and thence through the shaft Bin order to hold the shaft firmly in connection with the base or support, as will be understood from Fig. 3 of the drawings.
The main frame has its base-beams A extended at one end at A beyond the path of the revolving moldboxes, and on this extension A is mounted an upright E, which extends upwardly, as shown, nearly to the top of the mold-boxes F, and is provided at its upper end with a locking-bar E, by which the moldboxes are secured in position for the action of the prcsser-heads, presently described. As shown, the locking-bar E is pivoted at e to the struts G, and is notched in its free edge to engage with a pin on the outer sideof the mold-box, as best shown in Figs. 3 and 5 of the drawings. A strut-beam G is secured at its lower end to one of the basebeams A and at its upper end to the upright E, and is provided between its ends with boxes G and G, forming guides for the carrying-bars H and I of the presser-heads H and I, the former operating from above and the latter operating from belowinto the mold boxes for the purpose of pressing the concrete in the mold-boxes, as will be understood from Fig. 3 of the drawings. I also provide. one of the base-beams A with boxes h and 7L2, forming guides for the lower ends of the bars H and I, so the latter are guided accurately into and out of the mold-box. in the operation of the invention. As shown, the carry ing-bar H for the presser-head I-I extends on a straight line throughout its length, while the carrier I is provided at its upper end with a forwardly-projecting portion I to support the presser-head I drectly above the moldbox. To operate the presser-heads, we provide a rocking disk J, having a shaft J, to which the handle-lever J is secured, and this rocker J is connected by links it and i with the carrying-bars of their respective presserheads, so that as the rocker J is operated the presser-heads will be moved reciprocally and operated into and out of pressing position. As shown, the top beams B are metal bars diverging from a central block K at the top of the shaft B to a point near their outer ends and having such outer ends 7) extending outwardly along the outer sides of the moldboxes F and secured to thebase-frames of the said mold-boxes, as will be understood from Figs. 1 and 3 of the drawings.
lhe mold-boxes have the open bottom frames F, the inner side sections F, the outer side sections F and the end section F The sections F and F are hinged at f at their lower edges, so they may turn outwardly, as shown in Fig. 4, and these sections are provided on their inner sides with the longitudinal inwardly-projecting rounded ribs 1, which form the longitudinal channels in the sides of the concrete block when the latter is completed. The end sections F are also provided on their inner sides with the inwardly-projecting ribs 1., and these end sections F- are hinged at one edge f" to the outer section F of the moldbox and are provided with locking devices F for securing the outer side section F, such locking devices comprising pivoted bars having on their outer sides near their swinging ends projections f which interlock with projections f on the outer side section for securing the latter when the mold-box is closed. By the described construction the mold-box may be opened to discharge a pressed block and then closed and secured in conditionto receive the loose concrete for forming another block. The side sections F and F are provided with openings 2 and 3, in which operate the transverse core-blocks K, which are preferably round in cross-section and are of such length as to extend when applied to the box entirely across the same, as shown in Fig. 1 of the drawings. These core-blocks K are connected at their inner ends by a cross-bar K, to which is connected a sliderod K passing through a guide L in a guidebar L, and a lever M pivots at M between its ends and connects at M by a sliding connection with the slide-bar K so it may be operated to throw the coreblocks into the advanced position shown in Fig. 1 or to retract the said blocks so they will clear the mold-box when it is desired to open the latter and remove the pressed block. As shown in Fig. 4, the inner side section F has a limited opening movement, being stopped by a bar N projecting from one of the top beams, and the core-blocks are sufficiently loose in the openings 3 to permit the section F to adjust to the position shown in Fig. 4 when it is desired to remove the pressed block.
After the block has been pressed the coreblocks may be drawn out of the box by means of the lever M, and the locking-bars F may be adjusted to release the outside end doors or sections, and the end doors may be opened, which will cause the inside door or section to tilt away from the press block. The outside section may now be turned down when the block is free and can be removed from the machine. To close the mold, the empty pallet or platen 0 should be placed in the bottom of the mold. The latter has a metal plate 0, which will move upward as the lower press-head H rises. This will cause the pallet O to move upwardly past small clutches P, which will hold it until the pressed block is removed, and the doors or sections may be closed and the coreblocks adjusted to the position shown in Fig. 1, and the mold-box is ready for refilling. v
Each press-box contains four dogs P, one at each corner, and the plate 0 is a loose plate which remains in the base of the press box and is provided with openings in which the points of the dogs P operate, as will be understood from Fig. 6. When the lower press-head comes in contact with the loose plate 0, it elevates the latter, and also the pallet or platen O, the corners 0 raising the dogs P. When the pressing operation has been completed, the dogs, the plate 0, and the pallet O assume the position indicated in dotted lines, Fig. 6, the springs P on the under sides of the dogs pressing against the corners O and forcing the ratcheted surface P into engagement with a corresponding surface on the under side of the pallet O and holding the pallet and dogs in position. When the lower press-head is lowered, the loose plate 0 will fall to its original position, as indicated in full lines, Fig. 6, and when the pallet O is removed with the press-block the dogs P will fall to their initial positions, as shown in full lines, Fig. 6, and an empty pallet or platen 0 may be placed in position when the press-box is ready for another char e of concrete. Any suitable. design of top. ace may be secured by changing the top presser-head I, the latter being preferably removable, as indicated in Fig. 3, so that different designs may be provided.
In operation after the block has been pressed in the position shown in Fig. 3, the lock E may be released and the revolving carrier turned to bring another mold-box into position between the press-heads, and the pressed block may be removed after the box has been adjusted clear of the pressheads, as will be understood from Figs. 1 and 3 of the drawings.
