Boiler fronts are made in many different styles, almost everymaker having some peculiar points in design that he uses onhis own hollers and which nobody else uses. In the illustrations here given may be seen the four princi-pal designs : 1. The flush front is shown in Fig. 72, 2. The overhanging front as seen in Fig. 73. 3. The cutaway front. Fig. 74. 4. Fronts with breaching as shown in Fig. 75. The flush front is one of the earliest forms of fronts, andthough it often gives good satisfaction, yet it is liable to cer-tain accidents. i66 Maxims and BOILER FRONTS. Ai will be seen from cat72, the front of tbe 5mokearch, in tliis form of setting,is flush with the front of thebrickwork, and the dry sheetjust outside of the fronthead is built into the brick-work. The heat from thefire, striking through thebrickwork, impinges on thissheet, which is unprotectedby water on the inside. Solong as the furnace walls arein proper condition the heatthus transmitted should notbe sufficient to give trouble;but after running some timebricks are very apt to fall FrootforWaterTube 71. away from over the fire door, and thus expose portionsof the dry sheet to thedirect action of the fire,causing it to be burnedor otherwise injured bythe heat, and perhapsstarting- a leakagearound the front rov?- ofrivets when the head isattached to the shell. In the overhangingfront this tendency isentirely prevented bysetting the boile
