Description: |
| Luther T. Mack - patent attorney
My invention relates to and has for an object the provision of an improved all angle, full universal milling attachment which is adapted to be mounted on the overarm of a milling machine, and is capable of many and certain micrometric operations heretofore impossible of performance with other types of milling attachments, and moreover, is subject to a more convenient, accurate and efficient use in any of its possible positions and operations.
One of the important purposes of my invention is the provision of an attachment of the character described wherein the major axes of adjustment and the parts and elements thereof are so constructed, compactly arranged and closely coupled as increase the strength and stability of the attachment without sacrificing the full universal and all angle adjustments and primarily, to insure accuracy of work in all positions.
One of the important features of my attachment is the provision of an improved quill arrangement by means of which the tool may be fed to the work at all angles and positions in a much more convenient and accurate manner than heretofore possible.
Another important provision of my invention is that of a novel stop means for limiting the feed and particularly the depth of feed of the tool in a most accurate and efficient manner.
Another purpose of my invention is to provide an attachment of the character described in which independently and selectively operable feed means for the quill will make possible accurate and micrometric feeding of the tool to the work to best suit the particular work at hand and many milling operations not otherwise possible.
A further purpose is to provide an attachment of the character described which may be readily and easily disposed in an out of the way position when it is desired to use the milling machine proper, exclusively of the attachment.
Another purpose of the invention is to provide a milling machine attachment of the character described which includes an improved construction of the spindle housing and mounting means therefor, which latter provides a rotative joint on a horizontal axis close and at right angles to the axis of the overarm to facilitate an accurate positioning of the attachment at any angle desired.
Among other features of improvement my invention includes the advantages of such added stability and strength as to enable the work to be finished in one operation or cut, and also provides for a highly desirable micrometric feed whereby small and other work may be accomplished in a highly satisfactory manner. Again, the attachment makes possible grinding, lapping, and drilling and many other operations by reason of the stability, ruggedness, adjustments and feeding provisions as hereinbefore pointed out, and is further improved in that all wearing parts may be properly adjusted to compensate for wear in a particularly novel manner. |
