The replacer which the Buda Foundry & ManufacturingCompany has recentlj put on the market lias several impor-tant features, the advantages of which hav< stratedby numerous tests. One of these, which is clearly shown inthe accompanying engraving, is the groove that protects theflange by allowing the tread of the wheel to first engage thereplacer preparatory to mounting. The increase in the fric-tion thus secured is very apparent. The tendency to shove thereplacer out of position is also overcome, and there is no f- 6 SQUAHE HOLE 4 6USSS SCTOj I. -APPLICATION OF VENTILATOR TO SIDE DECK. accommodating itself in operation to the direction of the 1 shows in elevation its application to the side deck of acar. It is shown in sectional elevation in Fig. 2 and in sec-tional plan in Fig. 3. It is applied in connection with the deck sash openings, thescreen being removed and a frame for the ventilator beingsubstituted provided with glass, except for the 6-in. squarescreened opening for the ventilator connection.
