| William B. Wood - patent attorney
My improvements relate generally to that portion of the mill to which the cutting-tool is attached, and by which its feed movements are effected, controlled, and adjusted for the proper performance of the great variety of service for which such mills are generally intended. My invention consists, first, in a novel combination of the horizontal cross-head screw, gearing, and slide, by which the slide, with its swivel and tool-spindle, may be moved to and fro on the cross-head without the rotation of the cross-head screw; secondly, in a novel method of adjusting the swivel on the slide, and in controlling or actuating its movement, by which the tool-spindle may be set at any desired angle in a plane parallel with the vertical face of the cross-head; thirdly, in a novel method of mounting the "tool-boot" on the spindle, by means of which the tool may be set at any desired horizontal angle radiating from the central axial line of the tool-spindle; fourthly, in a novel method of sustaining the weight of the tool-spindle, by means of which all loose longitudinal play of the spindle in its housing is effectually prevented; and also in certain other less important features, hereafter more fully described; and I do hereby declare that the following specification, taken in connection with the drawing furnished and forming a part of the same, is a clear and true description of an apparatus involving the several and combined features of my invention. |
