JUST to show how you never know where you’re going in the Navy, we had the U.S.S. North Carolina heading due East on page 86 of the August issue of P.S.M., but here just a few weeks later she is turned around and streaking West. Anyway, Secretary Knox looks pleased, and I was sure proud to present him with this westwardbound job.

A SAFE and sturdy trailer hitch for motorcycles, patented by Vincent Rea t of Brooklyn, N. Y., has served its inventor successfully in trips from Maine to Florida, and at speeds up to 75 miles an hour. No alteration of the motorcycle frame is needed to attach, with U bolts, heavy members that support a bed plate behind the saddle. A second plate swivels upon the first, between limits imposed by curved slots engaging a pair of bolts.

EITHER single or double-race ball bearings are suitable for the spindle bearings of the precision tool-post grinder (Fig. 11), provided that they are new and of good quality.

PRINTERS and press feeders, who have frequent occasion to tear small strips or squares of paper for proofing or make-ready on the press, will find that a large threecornered file serves better than a printer’s rule for this work. The weight of the file and the roughness of its surface against the paper prevents slipping, so the tear can be made quickly on the desired line.
