  • Selector device 33 is vertically displaceable by means of connecting rod 73 to respective positions which correspond to the outlet ends of chutes 23" to 26" being individually aligned with said slot 35.
  • the telescopic relationship between the chutes of body 27 and selector body 33 allows for such vertical displacement of body 33 without disturbing the alignment between chutes 23' to 26' and chutes 23" to 26".
  • a plate member 37 is pivotable in the horizontal gap between diaphragm 34 and body 33 along a stroke from an inoperative position in which plate 37 does not obstruct free passage between the slot 35 and the chutes 23" to 26" with which said slot is aligned, to an operative position whereby said plate 37 swings across slot 35 and by means of a camlike projection 84 on said plate serves to push a button 85, which extends into said gap, back into its chute in body 33.
  • selector body 33 results from actuation of a control means which is generally designated by numeral 33 and includes a support 39 and is fastened to table 13 and comprises a pair of spaced-apart projections 40 between which is rotatably supported a shaft 54.
  • a control means which is generally designated by numeral 33 and includes a support 39 and is fastened to table 13 and comprises a pair of spaced-apart projections 40 between which is rotatably supported a shaft 54.
  • Four parallely disposed selector members in the form of cylindrical pushbutton-type members 41 to 44 are mounted on support 39 for reciprocal linear displacement in a direction perpendicular to the axis of shaft 54.
  • the visible end of each of the push members 41 to 44 has mounted thereon a button d5 to 48 which corresponds, respectively, to the button contained in each of the respective tanks 15, 17, 18 and 19.
  • a cover'fi for the push members is secured to support 39 by screws 7.
  • FIG. 3 shows the details of one of the push members 43, the others being identical thereto.
  • Member 43 is reciprocally slidable within sleeve 50 from an inoperative to an operative position against the urging of coil spring 51 which extends within an axially extending bore 52 in member 43 with one end of said spring leaning against the button of said bore and the other end leaning against the button of a bore 53 in the support 39.
  • Each of the push members includes a radial notch 55 of rectangular shape for receiving lock member 33 therein in order to hold the push member in its operative position against the urging of spring 3i.
  • Each push member also includes an inclined or cam-type forward edge 56 which, as one push member is moving towards its operative position, is adapted to lift lock member 33 out of notch 35 of any other push member which is already in its operative position.
  • Each push member also includes a radially extending abutment member 57 located substantially centrally of the push member length. Abutment member 57 includes a forward abutment surface 58 for engaging a tongue portion 59 which is integral with body 60 which in turn is freely rotatably mounted on shaft 54.
  • a clamp device is rigidly secured to shaft 54 by screw means 61 which acts to tighten the two spaced-apart legs 62 and 63 of said clamp around the shaft.
  • a screw means 64 serves to adjustably determine the angular relationship between clamp and tongue 59. Clockwise angular oscillatory adjustment of tongue 59 is obtained by threading screw member 64 into clamp 5 while counterclockwise adjustment is obtained by unthreading screw member 64 from said clamp 5 whereby spring 65 serves to urge tongue 59 apart from clamp 5.
  • a second shaft 66 is rotatably mounted on support 39 parallel to shaft 54 and pivotally supports a lever L which includes an arm 67 extending radially from shaft 66 and another arm 67' extending perpendicular to arm 67 and parallel to shaft 54 across the path of all the push members 41 to 44.
  • Arm 67 is connected by means of a pivot pin 68 to one end oflink 69, the other end of which is connected by pivot pin 70 to the lower end of pivot plate 37.
  • Said plate 37 is pivotably mounted on a pin 71 which serves the additional purpose of securing the diaphragm 34 to a not-shown bracket which, in turn, is fixed to column 11.
  • a coil spring 72 fastened at one of its ends to support 39 and at the other of its ends to link 69, urges the pivot plate 37 to an inoperative position relative to slot 35.
  • connecting rod 73 is connected by a screw clamp 74 to one end of L-shaped lever 75 whose other end is connected to shaft 54 by screw clamp 76.
  • the push member is locked in its operative position so that the machine operator may release the push member
  • each projection 57 on each of the push members are slightly axially displaced from each other in order that each projection 57 corresponds to a different position of body 33 relative to slot 35. Furthermore, the point along the stroke of each push member at which its surface 58 abuts against tongue 59 can be adjusted through screw 64. In any event, body 33 will move either up or down depending upon the axial relationship of the projections 57 on two necessarily pressed push members. Body 33 is movable downwardly by virtue of its own weight while upward movement is imparted thereto by projection 57 abutting against tongue 59 as heretofore described.
