Definitions

  • rnnss non THE MANUFACTURE or ARTIFICIAL sronns, BLOCKS, BRICKS, on TH LIKE.
  • Still another object of the invention is-to provide means whereby the freshly pressed bricksd-espite their special cross section can. be removed fromthe press by mechanical means without damage,
  • the proper filling by means of a charging box is effected according to the invention by arranging on that part of the press table on which the charging box moves, that is, in .front ofthe mould openings, ledges or rails the upper 'surface of which corresponds shape 'to theupper, surface of the lower dies.
  • Inlth-e manufacture of wedge-shaped bricks .the-up per;lsurface. of thewledges or rails is slanting corresponding-to the slanting upper surface ofthe lower dies.
  • In the manufac- 'ture of profiled bricks -the ledges or rails are wprofiled in accordance with the particular profile .of the l-ower dies used at the time.
  • the rear and frontwalls of the charging box are provided with recesses into which the slanting or profiled ledges or rails fit.
  • 4 .Flg..;1 shows a. cross section through a press in whlchwed'ge-shaped bIlCkS'Wlih two '.inclinedfsurfacesare-made.i;
  • press table 1 is secured by the pillars 12 be- Fig. 2 is a plan of the press shown in .Fig. 1, whereby the upper press dies are omitted.
  • Fig. 3 is a section through the charging box 1 n its position of rest along a line X/X 111 Fig. 2 on an enlarged scale.
  • Fig. 4 is, also on an enlarged scale, a sect on along a line Y/Y in Fig. 2 through that side of the press table on which the finished pressed bricks are shoved oif.
  • Fig. 5 is a plan of a press table in which gulding ledges are only provided on the fill mg slde, the finished pressed bricks being shoved off on the level surface of the table.
  • Figs. 6-12 show various kinds of profiled bricks and the profiled guide ledges-to be arranged on the press table for this purpose 1n accordance with the invention.
  • Figures 1-4 apply to the arrangement of slanting table ledges as required for the The tween the upper press cylinder 2 and the lower press cyl nder 3. There are three mould opemngs 4 1n the press table 1.
  • the charging box-5 has in like manner three compartments. Each compartment of the charging box 5-is filled with pressing mass as required for one brick.
  • a cross-beam 7 is fastenedto the charing box by means of the bars 8, said cross beam, when the charging box is moved forward, driving the pressed bricks ejected from the mould openings gllong before out of the range 'of the press 185; Y Both thelower dies 9 and the upper dies 10 are provided with inclined heads in accordance with the slanting surfaces above and below of each wedge-shaped brick 8 to be made. p
  • Fig. 1 the press is shown at the moment in which, after finished pressing. the upper dies 10 have been withdrawn. 7
  • the Wedge shaped bricks 8 are still in the position in which they have just been compressed on V p j' the press dies 9 and are about to be ejected
  • the drawings illustrate theinvention by a.
  • the ledges or rails 11 provided with slanting surfaces are arranged onthe press table 1 before and behind the mould openings 4.
  • the slant of the surfaces ofthe ledges or rails corresponds to the slant of the surfaces of the lower dies 9, so that the surface of each ledge 11 forms a plane with the surface of the corresponding lower die when the latter on ejecting the wedge-shaped brick 8 is moved into its extren'ie upper position. Accordingly the wedge-shaped bricks 8, when the charging box is moved forward, can also he shoved along by the cross-beam 7 on the slanting ledges 11 behind the mould openings on the sideof removal without danger of disturbing the further pressing operations.
  • the front and rear walls of the charging box 5 are provided below with recesses (Fig. 3) in which the slanting ledges or rails 11 fit.
  • the pressing mass glides along on the slanting ledges 11 without disturbance until it arrives over the adjoining slanting surfaces of the lower dies 9.
  • the latter are now sunk down, whereby the pressin mass resting thereon follows, gliding out of the compartments of the charging box into the mould openings beneath.
  • This distribution of the pressing mass in the mould opening ensures the production of wedge-shaped bricks which as a. result of the exact distribution of the pressing mass throughout their entire cross section are compressed with absolute uniformity.
  • the press shown in Fig. 5 is intended for the manufacture of profiled bricks shown in side and plan in Figs. 10 and 11.
  • Three mould openings 4.- are. provided in the press table 1 for simultaneously pressing three bricks.
  • the charging box 5 glides on the side of the table in front of the mould openings.
  • the arched ledges 11 project through corresponding recesses in the walls of the charging box 5, serving as its bottom.
  • the pro file of the ledges 11 will be seen at 16 in section in Fig. 10 and corresponds exactly to the surface profile tobe used in this case, of
  • mould openings a No guideledges are provided in the example shown 111 Fig. 5 on that side ofthe press table on which the finished pressed bricks are shoved off by the cross-beam 7 into the position indicated by dotted lines, seeing that the profiled brick shown in Figs. and 11 possesses in itself a suliiciently large level resting surface, so that it can be shovedoff directly over an even table surface.
  • the profiled brick shown in side view and plan in Figs. 8 and 9 illustrates still another application of the invention.
  • This brick is cut out at the point on the upper and lower side.
  • the guide ledges 11 must correspond to the cutout on the lower side.
  • the advantages of the present inven tion become particularly evident in considering the ridged brick shown in "front view in Fig. 12 which on account of the ridges on its upper and lower surface pre sents to view a number of ribs 17 which require a ledge 11 of corresponding profile on the press table 1.
  • the profiled ledges arranged in accordance with the invention on the charging side of the press table ensure not only an acceleration of the pressing operationsby the charging box operating in connection with the ledges, but also a considerably improved compression and structure of the pressed bricks dueto the fact that the charge in the mould openings has been given before'com pression a similar shape to that of the pressed bricks. This furt-her'ensures a uniformpressing efiect on the entire pressing mass.
  • the new press table will also be used for making bricks which are only profiled on one surface and in cases where the brick can be pressed with the side not profiled turned downward. Even such bricks can in future be pressed better with the profiled side turned downward, in order to ensure a uniform pressing effect by previously giving the'pressing mass charge a form corresponding to the ultimate shape of the brick.
  • the ledges provided in accordance with the invention with slanting or profiled surface and arranged on the press table behind the mould openings ensure the removal ofthe pressed bricks without danger of injury.
  • the pressed bricks carried ofi by the charging box or the cross-beam connected with same slide conveniently along on the profiled show in front and side viewledges adjoining with the surfacebf the loo lower dies until they reach their places from which. they are taken off.
  • the pressed bricks accordingly retain their horizontal position without tilting during the course and, in the event of their having recesses in their lower surfaces, are further supported by the profiled ledges corresponding to these recesses.
  • the shoving off of the pressed bricks from the press is, accordingly, effected on a press table built along the lines set forth in the invention, without alteration of shape and without injury to the bricks.
  • a press for the manufacture of wedge shaped or otherwise profiled bricks comprising upper and lower pressing dies, a press table provided with a plurality of moulding openings and an equal number of guide ledges or rails, arranged before the mould openings and corresponding in shape to the upper surface of the lower pressing dies and a. charging box having the front and rear wall formed with bottom edges corresponding in shape to said ledges or rails.
  • moulding openings and an equal number of guide ledges or rails arranged before and behind the mould openings and corresponding in shape to the upper surfaces of the lower pressing dies and a charging box, shiftable on said ledges or rails.
  • a press for the manufacture of wedge shaped or otherwise profiled bricks comprising upper and lower pressing dies, apress table provided with a plurality of moulding openings and an equal number of guide ledges or rails corresponding in shape to the upper surface of the lower pressing dies and a charging box, shiftable on said ledges or rails and provided with a cross-beam for removing the pressed bricks from the mould openings.
