Definitions

  • Patented J an. 24, 1922.
  • This invention relates to apparatus for use in manufacturing concrete and like blocks, pipes, posts, girders, and the like, and in which a number of the articles are formed by centrifugal action in a plurality of simulta neously rotated moulds, and has for its object to, improve and simplify the construction of such apparatus.
  • the improved apparatus comprises a plurallty of parallel horizontal spindles mounted to rotate upon girders or other supports, chain and sprocket or other gearing connecting all of the spindles to one another so that each is positively driven and all of them in unison, means for driving one of the spindles by power, and a clamping device provided on one or each end of each spindle for positively clamping and holding a mould.
  • Figure 6 is an end view in section of the mould in position.
  • the apparatus shown comprises a plurality of parallel spindles a mounted to freely rotate upon two parallel girders b or other supports and geared to one another to rotate in unison, such as by means of chains 0 and sprocket wheels (1, one of the spindles being driven by power in any suitable manner, for instance through a belt and pulley 6.
  • One or both ends of eachspindle a is or are each fitted with a clamping device f for supporting a mould. In this manner moulds containing the material or materials of which the articles are to .be formed, are clamped in place in the clamping devices 7 and rotated simultaneously in one or two straight rows. All of the moulds may be of similar shape and dimensions, or they can vary within wide limits.
  • the moulds which are preferably of wood may be constructed as shown in Figures 4 and 5, so that they may be divided longitudinally to allow of the removal of the final concrete product.
  • the mould is nailed as at 16.
  • the bottom of the mould is formed by a metal plate 18 which is screwed to the two sections of the mould formed as described. This plate is slightly bent across the diagonal 20 so that the spring of the pitlte tends to force together the two sections of the mould along the edges 19.
  • the resilience of the plate allows the sections of the mould to be sprung apart sufficiently for the concrete block to be removed easily and without damage.
  • the mould is closed by means of a lid 21 which over the top end and is clamped to the mouid by it is maintained for a few minutes.
  • the lid has a circular hole into which a woodenplug 22 is fitted to prevent the mixture escaping when the mould is tilted for placing in the machine and in the initial stage of spinning.
  • each of the clamping devices comprise two opposed V or other suitably shaped brackets 10 one of which is fitted with a movable inner lining or clamping plate 11 of V or other cross-sectional shape, pins 12 rigid with said lining and guided through bosses formed upon the bracket, springs 13 surrounding said pins and tendingto retain the lining within a recess formed in the inner face of the bracket, and a cam lever 14 pivoted upon the bracket and adapted to project through a slot 15 formed in the latter, and to act upon the lining.
  • brackets 10 and /or the plates which carry them are preferably slotted to enable said brackets to be adjusted upon said plates and radially relatively to the spindles a.
  • Apparatus for use in manufacturing concrete and like blocks, pipes, posts, girders and the like comprising in combination a horizontal spindle mounted to rotate upon 2.
  • Apparatus for use in manufacturing concrete and like blocks, pipes, posts, girders and the like comprising in combination a horizontal spindle mounted to rotate upon supporting means such as girders, .power transmission gearing connected to said spindle whereby it is positively driven by power, two opposed brackets carried by at least one end of said spindle, movable clamping means situated upon the inner side of one of said brackets, means carried by said bracket for quickly moving said clamping means relative thereto and a mould secured between said brackets by said clamping means.
  • Apparatus for use in manufacturing concrete and like blocks, pipes, posts, girders and the like comprising in combination a plurality of parallel horizontal spindles mounted to rotate upon supporting means such as girders, power transmission gearing connecting all of the spindles to one another so that each is positively driven and all of them in unison, means for driving one of the spindles by power, a clamping device at both ends of each spindle and a mould secured by said clamping device for rotation about a horizontal axis coinciding with that of the spindle. 4.
  • Apparatus for use in manufacturing concrete and like blocks, pipes, posts, girders, and the like comprising in combination a plurality of parallel horizontal spindles mounted to rotate upon supporting means such as girders, power transmission gearing connecting all of the spindles to one another so that each is positively driven and all of them in unison, means for driving one of the spindles by power, a vertical face plate attached to at least one end of each spindle, two opposed brackets carried by said face plate, a movable clamping plate lining within one of said brackets, a cam lever adapted to engage and secure said movable clamping plate, and a mould secured between said brackets.
  • Apparatus for use in manufacturing concrete and like blocks, pipes, posts, girders and the like comprisin in combination a plurality of parallel perspectiveal spindles mounted to rotate upon supporting means such as girders, chain and sprocket gearing connecting all of the spindles to one another so that each is positively driven and all of them in unison, means for driving one of the spindles by power, a vertical face plate attached to each end of said spindles, two opposed brackets carried by said face plate and radially adjustable thereon, a movable clamping plate lining Within one of said brackets, a cam lever adapted to engage and secure said movable clamping plate, and a mould secured between said brackets for rotation about a horizontal axis coinciding with that of the spindle.
