order of 45 u00b0 if so the fastening flange 28 of the shield 26 is correspondingly inclined to lie flat against such surface from the fastening flange 28 the shield has a forwardly extending horizontal portion 32 that terminates in a downwardly depending vertical portion 34 that is disposed in spaced relation with and in front of the spindle area as shown in fig2 the spacing between the depending portion 34 and the doors 22 is sufficient to permit free access to the spindle area by reaching under the shield 26 with the hands wrists and portions of the forearms of an operator standing in front of the machine while maintaining such spacing at a minimum a spacing of the order of 5 inches has been found to be sufficient for this purpose the height of the depending portion 34 of the shield 26 is sufficient to cover the frontal area of the bank 12 to prevent a flying disc piece from striking any part of an operator except the hands wrists and forearm portions mentioned above the lower edge 36 of the shield 26 is high enough to enable an operator to reach thereunder for necessary manipulations in the spindle area in actual practice it has been found that a depending portion height of the order of about 8 inches will accomplish the foregoing objectives the horizontal and vertical portions 32 and 34 of the shield 26 may be joined by a relatively narrow portion 38 inclined at an angle of the order of about 45 u00b0 but this is not essential further the shield 26 could consist of only the depending portion 34 which.
