Description: |
| Luther T. Mack - patent attorney
This invention comprehends the provision of an improved type of milling machine which combines certain features of heavy duty machines of restricted scope and adaptability with features of my invention hereinafter identified, and a primary additional characteristic including a new type of over-arm which is arranged for rotatable adjustment on a base, to an extent of 360 degrees, and is otherwise adjustable in right angular directions on the rotatable head for at least two purposes, to-wit: First: The operative support of an all-angle auxiliary milling attachment having an integrally supported motor which is so mounted as to afford adjustment of a tool relative to the work about two or more axes to an extent of 360 degrees or less and otherwise in different horizontal, vertical and inclined planes.
Second: The provision on the base of the machine of a usual tool spindle driven by a separate motor and an out-board bearing for the tool arbor which is carried by the over-arm and is arranged to be operatively and inoperatively positioned, at the will of the operator, through the rotatable and horizontal adjustment of the over-arm on the head.
An object, therefore, is to combine in a milling machine, the hereinbefore mentioned features accompanied by suitable devices for effecting the adjustment of the several elements and for supporting the elements in adjusted positions.
Thus, the tool or tools required for different operations may be adequately adjusted and supported for performing various operations on the work, either by a single tool carried by the horizontal spindle or by the spindle of the all-angle attachment, or as in some cases, by tools carried by both of such spindles for simultaneous operations on the same or different pieces of work.
In considering my present invention I refer to the following pending applications for patent in which structures as shown therein with or without modification, may be utilized for attaining the objects of the instant invention: Serial No. 319,290 filed February 16, 1940, Patent No. 2,349,199; Serial No. 357,021 filed September 16, 1940, Patent No. 2,288,648; and Serial No. 376,324 filed January 28, 1941, Patent No. 2,296,573. |
