EMIL SPRENGER, OF GOLDAOH, SWITZERLAND.
BLOCK-PRESS.
Specification of Letters Patent.
Patented June 1, 1909.
Application filed. March 24, 1908. Serial No. 423,058.
To all whom it may concern:
Be it known that I, EMIL SPRENGER, a subject of the Swiss Republic, and resident of Goldach, Switzerland, have invented a Block-Press, of which the following is a specification.
The subject of this invention is a press with revolving molds for manufacturing shaped bricks.
The accompanying drawings give several views of the invention.
Figure 1 is a front elevation of the press partly sectioned. Fig. 2 is a side elevation partly section. Figs. 3-7 illustrate various details.
A toothed wheel 8 is provided at each end of the shaft 3 between the bearings 1 and 2. The toothed wheel shown on the left in Fig. 1 has on its right side two diametrically opposite notches, in which a spring actuated pawl 26 fixed to the bearing 2, can engage. By this means the toothed wheel can be stopped after every half revolution. The toothed wheels 8 carry molds 7, which are fastened between the two wheels and opposite to each other. These molds are divided into compartments 7, in each of which a close fitting press plate 12 can slide to and. fro. Each opposite pair of these plates is detachably fixed to a yoke 18, a pin 6} projecting into the back of the plate, fixing the same securely in position. All these yokes 18 are seated on two parallel shafts 19 which are provided with rollers 20, the distance between these shafts 19 being fixed and unadjustable.
In the position of the molds shown in Figs. 1 and 2, (filling and discharging position) the upper shaft 19 lies with its rollers 20 on the upper surface of the cams 6. In this position the upper plates have been drawn back as far as possible, while the lower ones have been pushed as far down as possible. When the molds are in the upper position, they are ready for filling and subsequent pressing after being closed at the top. In the lower position, the molding boxes are emptied as described below. The cams 5 are inclosed by adjustable rods 22 which are rigidly connected by cross bars 22 so that when the toothed wheels 8 and molds 7 revolve about the axis 3, one of the two cross bars 22 slides over the rollers of the cam 5. By this means the rods 22, are prevented from moving till the wheels 8 have performed a quarter revolution starting from the position shown in Fig. 2. The rods 22 carry pins 23 at their ends. The mold shown at the top in Figs. 1 and 2 when filled with the material to bepressed, is covered with the plate 25. The latter is then held securely bythe lid 21, which also serves as a counter resistance against the force'of the press. This lid is detachably secured to the rod 22, by hooks 24 which engage with the pins 23, two of these hooks being revolubly fixed to pins 21 on each side of the lid. The two hooks 24 shown in front of Fig. 1, and to the right in Fig. 2, have prolongations 24 being thereby converted into levers. A small driving wheel 14 is mounted outside the bearing 1 and is revolved by means of a crank 15. This wheel engages with the toothed wheel 13 on the shaft 13*, and on this shaft, between the bearings, small toothed wheels 9 are mounted, which'engage with the large wheels 8 and revolve the latter together with the molds upon-the fixed shaft 8.
The molds are filled by means of a hopper 16 closed at the bottom, which is movably mounted on two horizontal guide bars 16*, (only one of which is shown) and is rovided with a clearing plate 16 The hopper is filled and slid over the empty molds. The bottom is then opened and the molds are filled, the hopper being then drawn back to the position shown in Fig. 2. During this latter operation any material projecting beyond the mold is smoothed down and the superfluous material wiped ofi by the plate 16 When emptying the machine, a. carriage 17 running on rails below the lid 21 is employed. This carriage is provided with a lever, revoluble about the axle 17 and when this is pressed down, the part 17 of the carriage to which is fixed the angle 0 is raised. The angle 0 now presses on the prolongation 24 so that the lid 21, (Fig. 2) on the left, is detached from the rods 22. If the lid 21 is now raised somewhat by the part 17 the two hooks 24 (Fig. 2 on the right) release themselves from the pins 23 by their own weight, so that the lid is released from the rods 22 and lies upon the part 17 with the molded bricks. The part 17 is now returned to its original position, the carriage is drawn from under the machine, and the bricks are removed from the plate 25 and lid 21, while the latter are placed upon the upper molds which have been filled.
The machine is used as follows:The upper mold is filled with material as described before and is then closed by the plate 25 and the lid 21. The pawl 26 is then disengaged and by means of the crank, the toothed wheels are revolved in the direction of the arrow in Fig. 2, so that the molds 7 are revolved through 180 about the shaft 8. During this movement of the molds, the upper shaft 19, (in Fi moves along the rollers 6 of the cams T and (3 toward the right. In consequence all the press plates move outward, 2'. (2. into the molds. During about a quarter of a revolution, the eccentric 5 holds the lid 21 securely against the mold by means of the lower cross bar 22 the rod 22, the pins 23 on the rod, and the hooks 24 In this way the material is pressed. During the continuation of the turning, the press plates under the action of the cams (3 move still farther out, but since the cams 5 allow the cross bar 22 to make a movement downward and at the same time to the right, (Fig. 2) the material is not compressed any farther. The material and lid are pressed farther and farther outward till at last the lid assumes the position shown dotted in Fig. 2. The lid 21 is then removed with the brick as described above, and the process is then repeated.
In order to make the brick out of materials which require different degrees of pressure, the rolls 6 on the cams 4 and (5 are made detachable so that larger or smaller rolls can be used, so that the distance traversed by the press plates is greater or less as desired. The cams 6 are also provided with adjustable pieces (5 and according to the position of these pieces the plates sink to a greater or less degree in the molds when in their highest position. By this means the capacity of the molds is altered since in the position shown in Fig. 2, the upper shaft 19 lies on the piece 6 and not on the surface of the cam 6. The amount of pressure could also be regulated by inserting press plates of different thickness or by affixing liners to the press plates.
