Figure 2 is a rear view of one of the shoes.

Figure 3 is a sectional view on line 3-3 of Figure 2.

Figure 4 is a sectional view on line 4-4 of Figure 2.

Referring to the drawing, 1 designates the body of the brake shoe Which is longitudinally eurved, as usual to conform to the curvature of the Wheel., said body having a groove 2 formed in its front face for receiving the :io flange 2' of the locomotive Wheel.

The .body l has a recess 3 formed in its rear face, the end Walls 4 thereof being beveled, as at 5. It Will be observed upon reference to Figure 4 that the outer Wall 6 of the recess i s of less height than the inner Wall 7 thereof. The Wall 6 gradually increases in height between its ends in order that a stop 8 Will be provided, the purpose of Which Will be later explained.
