.collect the oil flowing from the milling cutters on the table and return it into a Well or reservoir from which it is supplied to said cutters.

It consists in certain novel features of construction and in the peculiar arrangement of parts as hereinafter particularly described and pointed out in the claims.

In the accompanying drawing like characters designate the sameparts in the several figures.

Figure 1 is a partial side elevation and vertical section on the line 1 1, Figs. 2 and 3, of a milling machine embodying' the pres ent invention; Fig. 2 is a plan v1ew of the work table; Fig. 3 is a vertical section of the tableand saddle on the line 3 3, Figs. l and 2; and Fig. 4 is a. longitudinal section on the line 4 4, Fig. l of the telescopic oil pipe connecting the saddle with the oil reser- Voir in the frame.

For the purpose of illustration the improvements constituting the present invention are shown as embodied in a plain milling machine, but with slight changes they are equally applicable to universal milling machines.

Referring to the drawing, a designates the frame or case, which is of: the usual box or closed form. It is provided in the lower part thereof with an oil reservoir b froln which oil is raised by a pum c through a pipe d and delivered to the mllling cut-ter e.

The work table f is formed near the ends with transverse oil intercepting channels g, which lintersect and extend below the bottoms of the usual T grooves or slots h. It is also formed along the front side with an open longitudinal channel z' running into the transverse channels g, and at the back side with a deeper longitudinal channel y', also running at the ends into the channels g.

Midway between its ends a discharge opening is formed through the bottom of the channel y', which is provided with a short piece of pipe or a nipple c extending a short distance below the bottom face of the table.

To exclude chips, shavings or other refuse frompthe channel y' it -is eoveredbelow the top of the table with a removable plate Z, and the transverse channels g are provided at or below the level of this plate and of the bottoms of the grooves h with removable screens m.

The saddle or table support anon which the table f is mounted and moved by the usual feed screw o, is formed with a channel p below and parallel with the channel j in the table.

A longitudinally channeled and movable i slide q is fitted into a recess above the channel p flush with the top face of the saddle. It isl provided midway between its ends with a discharge opening 1' through the bottom into the channel p, and into the channel in its upper side the discharge pipel or nipple /c projects. The saddle is mounted in the usual manner upon the vertically adjustable knee s, and is adjusted thereon toward and from the frame by the screw t, in the usual manner, the knee being adjusted vertically by the screw u. y

A telescopic pipe n having jointed connections fw with the saddle n and frame a, connects the channel p in the saddle with the oil reservoir b in the frame. The oil reservoir b is provided with a partition or baffle plate m between the intake of the pump c and the connection of the pipe n, so that impurities carried with the oil into the reservoir through said pipe will not be taken up by the pump and delivered to the milling4 cutter.

As to the collection and return of oil from the work table to the reservoir from which it is supplied to the milling cutter, which are the essential functions of the present invention, the machine operates as follows: The oil delivered by thepump c to the cutter and flowing therefrom upon the table f, is caught and conductedby the grooves lt and channel c' and the cover plate Z of the channel y', upon the screens m in the transverse channels g, from which it flows into and through the channel j below said plate, and

is discharged through the central opening and nipple kfinto the channeled slide g. In

case the traverse-of the table carries the oil discharge opening therein beyond the limits of the saddle on which it is mounted, the nipple lc engaging with the ends of said slide, will carry it along with the table, thus maintaining' constantcommunlcatlon between the channel in the slide and the dis' ment of the saddle with the knee and theI lateral adjustment of the saddle on the knee and maintain a constant conduit for the return of oil from the saddle to the reservoir.

In the application of the system to a universal milling machine the channeled slide g is mounted in the upper part or section of the saddle or table support, usually called the swivel block, and the channel in the lower part or section of the saddle into which saidslide discharges and with which the telescopic pipe o connects, is formed on a. curve concentric with the swivel center, so as to permit of the angular adjust-ment of the table without interrupting or interfering with the continuity of the n oil discharge conduit.

Various changes in the details of construction and arrangement of parts may be made without departing from the principle and intended scope of the invention.

. IVe claim: j
