OIF CIN'CINNATI, OHIO, ASSIGNORS T0 TEE CINCINNATI PLANER COMIPA .NY, O]? CIN CINN ATI, OHIO, A CORPORA'IION OIF OHIO METAL ZELAN'ER Origine! application filed February 16, 1922, Serial No. 537,061. Divided and this application filed April 8, 1925. Serial No. 21,657.

Th1s application is a division of our copending application Serial No. 537 ,061, filed -February 16th, 1922, and hasas its -object the provision of a work supporting end moving table in planers, which provides for disposal of the metal chips resulting from the action of tools on the work, without getting into the Vs: and other operating parts'for the table.

. We accomplish our object by providing a table in which a hollow -constrtlction is pravidecl, ami openings are l eft from the T slots in which the Work retaining' elements find a seat, into theinterior of the table. The table is formed with lateral openings through which chips may be scraped or swept, thus taking thern out at the sides of the table.

We accomplish our object by that certain construction and arrangement of parts to be hereafter more specifically 'pointed out and claimed.

. In the drawing:

Figure 1 is a perspective ,section taken through the work table of a pl'aner.

Figure 2 is a larger scale perspective section illustrating our construction in its preferredform.

WVe have not illustrated the usual bed and other parts of a planeryas our table is to be employed in the usual way of planer tables, and tables having similar movementin other types of metal working machines.

The table shown is in the form of a box havinga base 1, on which are the usual Vs 2, 2. The top 3 ofthe table has the usual T slots 4 for the clamps that hold the work down on the table. In the u sual laner table having such a top, the practice o wiping the chips that collect in the Tslots ot through the ends of the slots, results-in the chips falling onto the V-gr'ooves in which the Vs of tlie table are guided and held, and also falling through into the operating parts that move the table.

Also the chips falling on the table work out through the ends of'the grooves, end fall down onto the planer bed.

At the present, the operation of clanng the table by sweeping off the chips to the side thereof, results in filling up the grooves, and

ments of the table, and in the bass of the T Slots We fonia series of holes 8 of any desired conformation and extent, tlirough which metal chips Will fall, passing to the insicle of the box-like table.

The location of the connecting webs, and of the holes'in the bases of the T slots can naturally be variedwidely without departing from the spirit of or invention.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent, is

. 1. In a metal working'machine a table for carrying work past the tools, said table being formed with a hollow interim, grooves in the table extending the full length of saicltable for engagement With work clamping devices, ami spaced openings extending throughout the interim of the table, arid means for access into the interior of the table foi removal of metal particles falling throughsaid open:

ings, and webs reinforcing'the grooved portion s of said table.

2. In a metal working machine a table for .carrying work past the tools, said table being formed with a holloW interior, side openings in the table lying at their lower edges flush with the interior of the base thereof, grooves in the table xt'endin throughout'thelength of said table for the location of work clamping devices, webs.extending across said hollow interior from said base to said groove portions find spaced apertures extending through the length of said grooves communicating with the interior of the table through which accumulated metal partieles can be sivept, said particles then. being removable through the openings in the table sides.
