For removing driving boxcrown brasses a horseshoe plate made of X^-m. stock is bentas shown at M, Fig. 2. The box is mounted on the horse-shoe and a flat plate N of suitable size is used to press theold brass out of the box, also using a key as heretofore ex-plained. The horseshoe M is not needed when applying thecrown brasses to the boxes as the latter can then be placeddirectly on the cast iron plate and while in this position it isimpossible to press the brasses in the box too far as some-times happens with other types of presses. Plate N also ismade in different sizes to suit the various types of drivingboxes and is used in both cases whether applying or remov-ing brasses. A 24-in. by 36-in. reservoir is used as a storagedrum to supply air for raising the piston. DEKiqES. OM*r New Planer Designed for Maximum Service THE necessity of reducing the cost of planer work byconserving every possible moment of the operatorstime was the guiding thought behind the design of thenew Maximum Service Planer made by the G. A. Gray Com-pany, Cincinnati, Ohio. The novel features incorporated inits design are all intended to increase the production capacityof the machine and provide maximum ease of operation. The method of adjusting the new Cantslip positive feedis by turning a knob at the operators end of the rail until the required feed is indi- cated on the graduateddial. A partial turn of thewrist gives any feed in. to 1 in. in steps ofone-hundredth of an feed dial is automatic-ally locked as soon as thefingers are removed fromthe knob. As will be seen in Fig. 1the feed mechanism for therail heads is mounted onthe end of the rail, that forthe side head is mountedon the head itself, and thusis always within conven-ient
