MILLING- AT'IACHMENT FOR METAL-WORKING MACHINES.

Patented Feb. lit, 1919.

Application filed November 16, 1917. Serial No. 202,308.

being employed as a matter of convenience but comprehending the applicability of the device to metal working machines of various types including lathes, milling machines, and similar apparatus,

Attachments for performing the functions of this invention now well known are all limited as to use to such an extent that they are suitable for only certain kinds of work, and in applying them to lathes, for example, especially of small size, so much room is occupied by the mechanism of the attachment that there is little space for handling work. This has led me to devise the present apparatus of such construction as to give it the greatest latitude of adjustment so that it is what may be called a universal construction or one characterized by the absence of the restrictions hitherto ob-- served in apparatus-for the same purpose.

To this end the device is intended for attachment to the cross slide of a lathe either directly or indirectly, by a special plate which is furnished, and in combination with the longitudinal movement of the lathe carriage, the transverse movement of its cross slide, and its own adjustment as hereinafter explained, practically all adjustments, hori zontal, vertical and angular, may be obtained as desired.

In the accompanying drawmgs:

. V Figure 1 isan end elevation of the attachment as applied to a lathe, including the angle plate work table intended for mach ning sections of rounds, squares, etc., whlch .do not" require indexing, said table being tilted at an angle from the horizontal as desired when beveling the end of a section or bar" 7 Fig.2 is a vertical sectional view on the plane indicated by the line 22 of Fig. 1; .Fig. 3 is a top plan view;

Fig. 4 is a fragmentary view showing the indirect application of the attachment to the lathe as by means of an extension plate;

Fig. 5 is a perspective view of the extension plate alone;

Fig. 6 is a front elevation of a vise attachment for use with this invention;

Fig. 7 is a vertical sectional view on the line 77 of Fig. 6;

Fig. 8 is a side elevation of the attachment as applied to a bench miller; and

Fig. 9 is a plan view of the device as shown in Fig. 8.

Referring to the drawings, Figs. 1, 2 and 3 show the construction of the milling attachment as arranged for plain milling, where indexing is not required, the same consisting of the angle frame or standard 1, the vertically adjustable slide 2, and the angle plate work table 3. At one side the standard is provided with a flat base 4 and spaced strengthening ribs 5, while on the other side, its front face, is a guide 6 on which the slide 2 is mounted, said slide being adjustable upwardly and downwardly by means of the handle screw 7. A circular flange 8 projects laterally from the slide and is provided with a circular slot 8 in which are received the T-headed bolts 9, in turn connecting thereto the correspondingly formed flange 10 of the angle plate work table 3 above mentioned.

The flange 10 is formed with a circular tongue 10 fitting in the slot 8 and it will be apparent that this construction permits of completely revolving the work table 3 about a horizontal axis so that work may be held in a horizontal or vertical position, as well as at any angle therefrom. The angle plate work table 3 is slotted as indicated at 11 to receive T-headed bolts 12 holding the clamp 13 for supporting the work on said table. A variety of work can he held on this angle plate work table, as many means are at the disposal of mechanics for clamping various pieces to the table as is now done on milling machines. This table can be inverted and work may be clamped to its under side, which will then be the top, and this will present a larger surface for certain pieces of irregular shape. In such enabling the scope of adjustment in the different planes which has hereinbefore been referred to and which produces a most practical apparatus for application to the various types of metal working machines that may be required.

Having thus described my invention, what I claim as new is:

1. The combination with a lathe or similar machine and cross slide thereof, and means for producing movement of the slide, of an attachment therefor including a supporting standard, a Work holding support mounted on said standard at one side thereof so as to be free to move above and below the plane of the cross slide aforesaid, and a connection directly connecting the said standard to the cross slide and about which said standard is free to com pletely revolve when above said plane whereby to hold the work at any angle in a horizontal plane.

2. The combination, with a lathe or similar machine having a cross slide, of an attachment therefor including an upright work holding support, the vertical face of which lies in substantially the same plane as the inner edge of the cross slide, said support having an offset base disposed upon the cross slide, and a pivot connection connecting said base to the slide, said support being adjustable about said connection to hold the work at any angle in the horizontal.

3. The combination, with a lathe or similar machine having a horizontally and transversely movable supporting member, of an attachment therefor comprising an upright standard having its base supported on said supporting member, a connecting member connecting said standard to the supporting member and permitting movement of the former completely about the connecting member, a slide mounted on said standard, means for adjusting said slide vertically to points below the plane of the lathe supporting member, and a work holding device having swiveled connection with said slide, whereby to afford longitudinal and transverse adjustments of the work and angular adjustments in both horizontal and vertical planes.

4-. The combination, with a lathe or similar machine having a cross slide, of an at tachment therefor comprising an upright standard having an angle base offset at one side, a pivot bolt connecting the base of said standard directly to the cross slide, a vertically movable slide mounted on said standard, and means for adjusting said slide, said vertically movable slide having its face provided with an annular flange, and an angle plate work holding device swiveled to the slide and having one edge arranged at a greater distance from its center than the opposite edge, whereby to support the work nearer or farther away from the tool held by the lathe.

5. The combination with a lathe or similar machine having a cross slide, of an attachment therefor comprising a standard formed with a laterally projecting base, work holding means mounted upon said standard, an extension plate secured to the cross slide and adjustable about its con nection with the cross slide, and a connection connecting the base of the standard to the extension plate and about which connection said standard is revoluble to adjust the work with respect to the slide and to anv' angle in the horizontal plane.

In testimony whereof I aifix my signature.

GEORGE F. WOOLSTON.
