Definitions

  • the present invention relates to improvements in separators for granular material of the type illustrated in my copending application Serial No. 573,408.
  • the particular object of the present invention isto provide a separating belt which will be an improvement upon the belt constituting one element of the apparatus of said earlier application.
  • the separating belt In the apparatus illustrated in the application referred to the separating belt consists of a body of suitable fabric from which project sprigs or pins providingv on the outer surface of the belt a series of pockets to receive particles of sand, loosened from a mass supported on the belt.
  • the several pins were each independently secured to the belt body and,therefore, it was difficult to maint-ain them in the desired relation to the belt.
  • the pins or sprigs 30 should each form a right angle with the body of the belt and the strains or stresses placed upon the points or free ends thereof had a tendency to enlarge the passages in the belt within which the'pins were fixed so that after a short time the desired right angle relation between the pins and belt was destroyed.
  • the object of the present invention is to provide a separator belt with sprigs of'such form that they will maintain the desired relation to the belt and by which the maximum amount of flexibility of the teeth will be provided without impairing or afiecting the connection between the several teeth and the body of the belt.
  • FIG. 1 is an elevation of a separator for V granular material including a belt constructed in accordance withthe present invention.
  • Fig. 2 is a transverse sectional view of the apparatus shown in Fig. 1.
  • Fig. 3 is a section through the improved separator belt, on an enlarged. scale, sub stantially on the line 3,3 of F 5.
  • Fig. i is a section onthe line 4+4 of Fig. 3.
  • FIG. 5 is a plan of Figs. 3 and 4.
  • Fig. 6 is a view similar to Fig. 4 illustrating a slight modification.
  • the apparatus illustrated which is of the form shown in the earlier application Serial No. 573,408, above referred to, comprises a supporting the parts shown in frame having a base or 'footcasting '1, a head cast1ng-2, an endless separator belt supported on driving rolls or pulleys 3 and 4,.a. hopper 5 adapted to laterally confine a mass of material supported on the upper run of thebelt, and an electric motor 6 for driving the separator belt at a relatively high speed.
  • r - In' order that the apparatus may be readily'movable from place to place, wheels 7 are provided for supporting the head cast ing 2 and a suitable handle 8is connected to the base casting 1.
  • the separator belt comprises a body 9 of fabric orother suitable material and the outer face of which is provided with a series of projecting sprigs forming small pockets which receive particles of sand dislodged from a mass supported on the upper run of the belt within the hopper. 5, as the belt moves beneath such mass, the collected particles being discharged by centrifugal force as they reach the upper end of the pathof travel of the belt about the supporting roll or pulley 3.
  • the several sprigs or separating points are not individually connected to the body of the belt. As shown, a series of such sprigs '10 are formed integral with a base member or flange 11.
  • the series of sprigs and base member 11 may be stain ed from a strip of spring metal, which 1s bent sothat the sprigs 10 will extend substantially at right angles to the base member 11, which is secured to the body of thebelt.
  • each set of sprigs is composed of three laminations or superposed spring metal plates, the
  • staples 12 acting to hold the members of each group in close relation and firmly secure them to the body of the belt.
  • the finger portions of the sev eral laminations are preferably made of different lengths, being gradually shorter from the front to the rear of each sprig. This is shown particularly in Figure 4.
  • each sprig may be varied. While good results have been obtained with-a construction in which each sprig is composed of three laminations or members as shown in Figure 4, it is possible that two-leafed sprigs, as shown in Figure "6. could beadvantageously used or, if desired, the number of laminations may be further increased.
  • the separator belt In operating a separator of the 'torm to which'the presentinvention relates the separator belt is driven at a relatively high speed, surface speed of from six hun dred (600) to nine hundred (900) feet per minute.
  • the mass of used moulders sand which may contain undesirably large particles of gravel, nails, pieces otmetal and other foreign material is deposited in the hopper 5 and rests upon the upper run of the belt.
  • the sprigs of laminated form are adapted toy'ield when striking a heavy piece of metal, for example, without liability of breaking or of loosening the connection by which they are secured 'to the body of the belt.
  • the sprig plates will 'beofsuc'h length that each will extend throughout the width of the operative portion of the belt.
  • a separator comprising a driven end less belt provided with outwardly projecting sheet metalsprigs arranged in rows extending transversely of thebelt, the'sprigs being arranged in groups and all the members of each group formed integral with "a base flange that overlies and is 'attached to the belt, and means for laterally confining a body of'materi'al'to be treated 'in the path o'ttravel'oi the free ends of thesprigs.
  • A'separator comprising-a driven endless belt, a seriesof plates each shaped to provide "a base member extending parallel to the outer face of the belt and an 'outwardly projecting member formed into a series of tongues or sprigs, means fastening into a series of tongues or sprigs, means extending through the apertures in the base members and securing the plates to the belt, and means for laterally confining a body of material to be treated in the path of travel of the free ends of the sprigs.
  • a separator comprising a driven endless belt, a series of laminated sprigs attached to the belt and extending outward therefrom, and means for laterally confining a body of material to be treated in the path of travel of the free ends of the sprigs.
  • a separator comprising a driven endless belt, a series of laminated sprigs attached to and extending outward from the belt, the individual laminations of each sprig being of difierent lengths, and means for laterally confinin a body of material to be treated in the pat of travel of the free ends of the sprigs.
  • a separator comprising a driven endless belt, a series of laminated sprigs attached to and extending outward from the belt, the individual laminations of each sprig being of decreasing lengths from front to rear of the sprig in the direction of travel of the belt, and means for laterally confining a body of material to be treated in the path of travel of the free ends of the sprigs,
  • a separator belt comprising a suitable body and a series of plates secured to the outer face of the belt and each provided with a plurality of integral outwardly proj ecting sprigs.
  • a separator belt comprising a suitable body and a series of plates secured toi the outer face of the belt and extending transversely thereof, each plate being provided with a series of integral outwardly projecting sprigs.
  • a separator belt comprising a suitable body and a series of spring metal plates secured to the body and each having a plurality of outwardly projecting integral sprigs.
  • a separator belt comprising a suitable body and a series of sheet metal plates, each plate being bent upon itself to form a base member, that is secured to the belt, and a member that extends outward from the baseand is slitted to provide a plurality of sprigs.
  • a separator belt comprising a suitable body and a series of sheet metal plates, each plate having a plurality of sprigs or spaced fingers along one edge and being bent upon itself to form a base, integral with and extending substantially at right angles to the length of the sprigs, that is secured to the body of the belt.
