E. KEEL. MACHINE FOR THE PRODUCTION OF HOLLOW BUILDING STONES.
APPLICATION FILED FEB. 24, I920.
Patented Nov. 23, 1920.
STATES PATENT orrics.
EUGENE KEEL, 0F LUCERNE, SWITZERLAND.
MACHINE son was raonucrion or noLLow BUILDING-STONES.
To all whom it may concern Be it known that T, EUGENE KEEL, a citizen of the Republic of Switzerland, residing at Lucerne, in the Canton of Lucerne, Switzerland, have invented an Improved Machine for the Production of Hollow Building-Stones, of which the following is a specification.
This invention has for its" object a machine for the production of hollow buildingstones. In constructing such hollow buildlug-stones of a relatively great height by means of presses, it often happens that the density of the stone at the side opposite the molding rammer or stamper is inferior to that at the side nearest to the stamper, and in order to eliminate this drawback, the material necessary for the construction of a hollow building-stone according to this invention is placed and pressed at least twice into a matricedie having an adjustable base;
Tn the drawing accompanying this speciiication the machine is shown by way of example. 1
Figures 1 and 2 show a front and side elevation respectively of the said machine; 3 is a sectional view, on a larger scale, of the matrice-die;
Fig. 4- is a plan, and Fig. 5 a side view of the same;
Fig. 6 shows a longitudinal section through the matrioe-die immediately after the removal of the building-stone, and
7 is a detail, showing the means for adjusting the aforementioned base plate.
To carry out my invention I make provision of a frame 1 of suitable form carrying a table plate 2. At opposite sides of this table and guided thereby are two vertically disposed racks 3 the teeth of which engage with cog-wheels 5 mounted on a common shaft 4 also carried by the frame 1. shaft 4 is provided at each end with hand lever 7 by means ofwhich the cog-wheels can be turned so that the racks'may either be moved up or downward. These racks are fork-shaped at their upper ends, the forks thus serving as bearings for the axle pins 8 of the matrice-die 9. The latter is of rectangular form and contains a base plate 11 having three openings 10 the plate 11 being so arranged that it is adapted to be vertically adjusted. At the underside of the plate 11 and at each of its two ends a slidable bolt 12 is mounted and guided in a Specification of Letters Patent.
member l3 in such a manner that it is pressed against the corresponding side walls of the matrice-die by means of a fiat spring 1 1; The said side walls are each provided with an opening 15 arranged approximately at the middle of the height of the wall'of' the die and serving as a rest for the bolt 12.
The ends of the bolts are beveled but so that they project only partly into theopenings 15 and assume the position shown in Fig. 7 when the matrice-die is readyfor the filling process. It will thus be easily understood that the degree at which the end of the bolt is slanted regulates or influences the degree of pressure to be exerted on the plate 11 in order to release it from its position Figs. 6 and 7 into the position indicated in Fig. 3.
The underside of the plate 11 is furthermore provided with a number of teeth 16 pointing downward and resting on another plate 18 carrying hollow cores 17, these teeth thus determining the lowest position of the base plate 11, Fig. 3. During the filling. of. thematrice-die, for instance with concrete, the hollow cores 17 project through the openings 10 in the plate 11 but do not reach the height of the upper edge of the die.'.
In theuse of my new machinethe filling takes place twice, firstly when'the plate 11 is in the uppermost position, Fig. .1, and secondly, when it is in the lower position indicated in Fig. 3. The pressing of the cement mortar is effected by means of a ramming or stamping device which, however, is not shown in the drawing. The face and adjacent parts of this Stamper, in order to press uniformly upon the concrete and insure the release of the bolts 12 on both sides'at the same time, must of course be made to correspond precisely with the hollow space limited by the matrice walls and the hollow cores 17 therein. Uponthe filling of the material in the former position of the die in which the room to be filled with concrete is limited at the bottom by the plate 11 at that time in the position indicated in Fig. 1, the bolts 12, after a sharp blow of the stamper, are caused'to be disengaged from the openings 15 in the sides of the matrice-die and the cementmortar and the plate 11 move downward; With the latter in the lower position the die is completely filled and the mold stamped till the desired degree of density is attained. In this way Patented Nov. 23, 1920. Application filed February 24, 1920. SerialNo. 360,972.
a building-stone is produced having hollow and canal-shaped chambers which open out at one end only. Before the removal of the building-stone from the matrice-die the latter is made to receive a plate 19 of reinforced concrete or the like one side of which, by means of a latch 20, is firmly gripped. If the plate 19 is made of concrete it must be well reinforced in order .to resist the abrasion and stress, due to the latch 20. The die so covered, for the purpose of removal of the building-stone, is then lifted by causing the racks to be moved upward until the die is above the cores 1?. The matrice-die is thereupon turned 180 degrees aboutits piv ots 8 and in order that it exactly assumes and keeps this vertical position of discharge, one of the pivots 8 has fitted thereon an arm 21 the turning movement of which is limited by a stop 22 fixed to the corresponding rack 3. The, racks 3 are subsequently lowered again until theplate 19 is made to rest on the cores 1?. The fastening device 20 is now released a spring 23 causing the gripping member to engage in a corresponding groove provided in the flange of the matricedie. I r
If therefore the latter, by means of the racks, is raised the. plate 19 and the building-stone remain on the cores 17 since, after the turning of the matrice-die, the molding stamper is made to rest on the plate 11 until the same returns to its normal position, that V is, until the bolts 12 engage in the openings 15. hen the die has been lifted sulficiently above the building-stone, such stone may then be removed with the aid of the plate 19 and placed upon a drying frame.
The die is thereafter turned about an angle 7 of 180 degrees and lowered on the core-plate 18, the aforedescribed process then being repeated. 7
This new machine presents the advantage that building-stone of a relatively considerable height and even density may quickly be produced whereby, in the case of' hollow building-stones, tne hollow chambers open combination, with a supporting frame and a.
rack mounted. at either side thereof, of
means for raising and lowering the racks, a r
hollow matrice-die journaled at the top of and situated between the racks, means to lzeepthe matrice-die in a vertical position, a base plate fitted within the said matrice-die and having a number of apertures, means to adjust the said base plate vertically within. the die and secure it in two different positions, and a second plate resting on the supporting frame and formed with hollow cores acapted to fit in and project through the said apertures, all substantially as and for Lllii purpose set forth.
2. In a machine of the type described, the combination, with a supporting frame and a rack mounted at either side thereof, of means for raising and lowering the racks, a hollow matrice-die journaled at the top of and situated between the racks and having an opening in each of its sides, means to re tain the matrice-die in a vertical position, a base plate fitted within the matrice-die and provided with a number of apertures, a slid.- able bolt mounted at each side of the base plate and adapted to engage with the opening in the corresponding side of the matricedie, springs tending to keep the bolts in engaged position, and a second plate resting on the supporting frame and formed with hollow cores fitting in and projecting through the apertures in the said base plate, all as for the purpose set forth.
In a machine of the type described, the combination, with a supporting frame and a rack mounted at either side thereof, of
means for raising and lowering the racks, a I
set forth.
In testimony whereof I have hereunto set my hand 1n the presence of two subscribing witnesses.
EUGENE KEEL.
