  Combined Polishing and Grinding Machine Valuable in Shopwork

  A combinted grinding and polishing machine, which has been proven by experience to be one of the most substantial now on the market, is shown in the illustration. This is also declared to be a very desirable type for garage shops which wish to use a grinding wheel on one side and a polishing wheel on the other side, having an extended arbor with ample room to polish large and bulky parts.

  It is a machine which has also been found exceptionally satisfactory for tire work, and is here shown with a rotary rasp and wire brush, ready for this class of work.

  This machine in made in five sizes, either with plain or tight and loose-pulley drive, all mounted on columns, or three of the sizes may be used for bench.

  The Saint Louis Machine Tool Co., also makes another line, under the trade name "Saint Louis," of which there are six sizes—either for overhead countershaft or self-contained countershaft drive. In addition, this company manufactures a full line of grinding and polishing machines, consisting of 120 different sizes and types. The outstanding features of these machines are: The bodies are all cored section, which distributes the metal very much better than solid section bodies; they all have self-oiling bearings, which is a feature of great importance in this class of machinery; all have 0.40 carbon steel arbors; all have square threads; pulleys are all forced on instead of set-screwed; and all bearings are lined with an extra high grade' of babbitt.

  The Saint Louis Machine Tool Co., 902 Loughborough Ave., St. Louis, Mo., has a first class catalog which it will be pleased to forward to anyone interested on request.
