Definitions

  • the principal object of this invention is a proceeding of mechanical cock-grinding by which cocks of all kinds may be readily ground to make them tight.
  • a further object of the invention is to provide a cock-grinder by which the cocks may be very rapidly and efiiciently ground.
  • Fig. 1 is a diagrammatic view showing the method of mechanical cock-grinding which has been used until now;
  • Fig. 2 is a diagrammatic View showing the new proceeding of grinding the cocks
  • Fig. 3 is a schematic vertical longitudinal sec- '20 tional view through the new cock-grinder according to the invention.
  • the conical surfaces of the two parts have not a common axis and both parts of the cock
  • cocks are ground not only better but also much faster.
  • the constrainedly moved part of the cock is the cockkey 2
  • the freely movable part is the cockbody 1; it might, of course, be arranged the other way.
  • the cock-key 2 is fixed on a vertical shaft 4 and is driven by a horizontal shaft 5 through the medium of the frictional propulsion 6, 7 and of cog-wheels 8, 9.
  • the lower end of the shaft 4 turns around freely in a bearing 10 at the upper end of a rod 10 which is widened at this end and provided with an opening. Through this opening passes the shaft 5 and in it is also placed a thumb-plate 11 which is fixed on the shaft 5.
  • Adjacent to the thumb-plate 11 is a roller 12 rotatably mounted between disks 13, 14, which cover the opening of the rod at opposite sides thereof and are connected with the rod.
  • the roller 12 is pressed against the thumb-plate 11 by a spring 15, the pressure of which is adjusted through a regulating nut 16.
  • the cock-body 1 is in this case fastened on part 17 of the ball-and-socket joint.
  • the other parts 18, 19 of this joint are so bedded in the frame that the ball-and-socket joint and with in a position in which the conical surfaces touch and rub along the common contact line.
  • a table In acock-grinding machine, a table, a ball and socket joint associated with the table, a support for a cock-body carried by said joint and. permitting universal tilting movement of a cockbody, a shaft rotatably mounted and extending through the joint and support, said shaft being adapted to support a cock-key through the body and means for reciprocating the shaft and key and at the same time imparting rotary motion thereto.
  • a table In a cock-grinding machine, a table, a ball and socket joint associated with the table, a support for a cock-body carried by said joint and permitting universal tilting movement of a cockbody, a driven shaft having an upper section rotatably and slidably mounted with its upper portion journaled through the joint and body support and adapted to support a cock-key in position to extend through a cock-body, a lower shaft section, a coupling connecting the upper end of the lower. shaft section to the lower end of the upper shaft section to permit rotation of the upper shaft section relative to the lower shaft section and cause reciprocation of the sections as a unit and means to impart rotation to the upper shaft section having an element serving to impart reciprocation to the shaft.
  • a table In a cock-grinding machine, a table, a ball and socket joint associated with the table, a support for a cock-body carried by said joint and. permitting universal tilting movement of a cockbody, a driven shaft having an upper section rotatably and slidably mounted with its upper portion journaled through the joint and body support and adapted to support a cock-key in position to extend through a cock-body, a lower shaft section, a coupling connecting the upper end of the lower shaft section to the lower end of the upper shaft section to permit rotation of the upper shaft section relative to the lower shaft section and cause reciprocation of the sections as a unit, a drive shaft rotatably mounted with a portion extending through an elongated passage in the coupling, a roller in said coupling, a cam carried by said drive shaft and engaging said roller to impart downward movement to the lower shaft section as the drive shaft rotates, a spring yieldably resisting such movement, a counter shaft, means for transmitting rotary motion from the drive shaft
