With the machine set up in this way. an air connectionis made to the pump cylinder, whose piston at once starts 382 RAILWAY AND LOCOMOTIVE ENGINEERING December, 1924 up an oscillating motion which is communicated to thecylinder head. The grinding can thus be done far morerapidly than by hand and with the expenditure of littleor no manual labor. The only change that need be made is to increase thesize of the spring for holding the head in place whenthe work is done on large cylinders. X L 1 EEi rzt. BEp afc^SSpE Push Car for Carrying Ptates As the position of the pump cylinder is reversed fromthe one which it occupies on a locomotive, it is necessaryto provide a means for holding the operating valve againstits seat, otherwise it would fall away from it as soon as theair supply was cut off. This may be accomplished byslotting the valve as shown in the drawing and holding itin place by a light spring E which may be made froman old clock spring. Push Car For Carrying Plates Push cars designed for a special purpose are somethingof a rarity. Here is one designed for carrying boiler platesfrom the storage platform to the shop. The moving of such plates on an ordinary push car isalways difficult, because, when laid fiat, they either inter-fere with the wheels or are too large to pass through theclearances or both. This car meets the difficulty by carry-ing the plates on edge. The wheel
