The latch used with the shield has the jaws cut at a right anglewith the bottom of the latch. This is because the stub leverscome through the top of the shield at this angle. Another ar-rangement of latch has the jaws cut at a sharp angle to ac-commodate stubs which do not come through the shield at aright angle. In this case if the shield had been set at a rightangle to the stub levers, the top would have been so flat that thecoal would not roll off.

The stub levers must extend far enoughthrough the shield to permit of the application of the shakinglever without moving the latch. The stub lever latches do not allmove in the same direction, like those shown in Fig. 2, becauseof the closeness of the stub levers; and in such cases it is neces-sary to make right and left hand patterns for the latches. Theshields are made to extend from the back head of the boiler to. Defai/ of MiM/e Sec f/on ofShie/d.

On engines which have shaker levers below the cab deck, ashield such as the one shown in Fig. 3 can be used with excel-lent results. This shield is made in three sections, as the deckopenings extend so close to the back head that it is necessary tomake the middle section of the shield more shallow than the sidesections, in order not to cover up the doors in the deck. It willbe noted that a different arrangement of latching is used in thiscase. This is because the stub levers are entirely below the deckflooring. The latch is hinged to the under side of the deck, anda catch is fastened to the stub lever in which the latch engages.
