Abstract: 332,775. Boksburg Brick & Fireclay Co., Ltd. April 19, 1929, [Convention date]. Combined moulding and re-pressing machines.- Brick-making machines, of the type in which clay is delivered under pressure by a pugmill to moulds at one point on a horizontal rotating table and the moulded articles are ejected from the table at another point into repressing means, are modified in the following respects. (1) The pugmill is replaced by a gravity feed and strickling of the over-filled moulds, (2) a counterbalanced separate plunger applies the initial pressure to the material formerly applied by the pugmill, (3) an adjustable bottom to the moulds provides compensating means for difference in the density of the material worked, (4) the ends of the moulds are cut-away and closed temporarily by fixed guides at the filling and pressing points, to facilitate the ejection by minimizing the lift necessary to detach the brick from the mould; and (5) stop means are provided for holding the table stationary during the pressing, ejecting, and feeding actions. Material from the hopper 12 falls through the hole 13 into the mould underneath and is strickled by the lower edge of the hopper in moving round on the table 2 which is driven intermittently by crank and ratchet gear 5, 4. A plunger 18 reciprocated by an eccentric 20 and counterbalanced by a pivoted lever 39, applies the initial pressure. Afterwards the tail-pieces 11 of the bases of the moulds ride up the ramp 28 to remove the bricks from the moulds into the path of the reciprocating ejector 30 which feeds the re-pressing machine 31. A vertical rod 24 is reciprocated in timed relation to the table so that it engages holes 27 and locks the table between each ot its intermittent movements. A ramp 37 can be set by screw-mechanism 38 to position the bottoms of the moulds at the filling station, and so vary the capacity in accordance with the density of the material treated. The cut-down ends of the moulds 32 and 33 are closed during filling and pressing by the fixed members 34, 35.

Abstract: 227,172. Stenman, P. L. Oct. 6, 1923. Turning wood-screws.- In a screw-cutting machine wherein a number of parallel tools follow one another into the working position, the tools are moved in a group along two guides wheteof one controls the contour given to the work and the other controls the path which the cutting-edges follow successively before, during and after the cutting operations. The tools 1, Fig. 1, are pivoted on a bar 5 about which they are oscillated during traverse by guides 2, 3 which may have a helical form, and the contour of the work is controlled by a guide 8 engaging the rear ends of the tools. Springs maintain the tools in contact with the guides 2, 3. In a modification, the tools are traversed in annular guides 2', Fig. 3, by arms 10, on a rotating shaft 9. The tools, which may have more than one cutting-edge, are axially adjustable in holders by means of screws 14, the holders having curved sides so that they preserve a uniform overall width throughout their traverse. The second guide again acts on the ends of the tools. The arms 10 are adjustable to accommodate different numbers of tools. In a further modification the tools 1, Fig. 5, are mounted on a shaft 30 and are guided by a surface 31 so as to move parallel to each other while being fed up to and along the work, and after the cut is completed their cutting-edges fall or are raised from the cutting plane by the guide 31, or the tools may be retracted. When the operation of all the tools is completed they are moved bodily out of the operative position by cams 42, 43, the former of which acts on a roller 45 attached to a rocking cradle 32 carrying the guide, while the latter oscillates a lever 46 which withdraws a locking-bolt 47 from the cradle. The contour of the work is controlled by springs 44 and a stepped guide 52 engaging the ends of the tools. The tools may slide along the guide 31 or the latter may be traversed with the tools.
