Specification of Letters Patent.
:Patented Dec. 5, 1905.
Application filed September 21, 1905. Serial No. 279,394.
and reinforce the shoeand hold the parts 4to-V gether in case ofl fracture and provide for securely uniting the strengthening means to the body of the shoe, at the same time employing the' strengthening means-to form the attaching-hook and to prevent the boltfrom pulling and breaking through the shoe.
In the Vaccompany-ing drawings, Figure l is a longitudinal sectional viewofa shoe em` bodying my invention.
Fig. 2 is a top plan view. Fig. 3 is a sectional view on the line 3 3 of Fig. l. l
I employ a plurality of strengthening-strips A B, which'are preferably made. of half-oval bar-iron, as shown 'inf cross-section in Fig. 3. These strips are'separated from 'each other and are arranged with their fiat faces toward the wearing-face of the shoe, and themetal forming the body C iows over the edges of the strips and securely locks the body and strips together.- Y
In the drawings I have shown three strips, the central strip A being somewhat wider than the side strips B, and one end of this central strip is Vbent up to form the hook D, which abuts against the end lug E. At the other end of the shoe the body is provided with a bolt-opening F, shaped to receive the head of the locking-bolt Gr, and the central strip A is provided with an opening f, which alines with the opening in the body and corresponds in diameter tothe smallest diameter of the opening in the body. This .construction prevents vthe bolt-head from pulling throughl the shoe, which would be'liable to occur if the wall of the opening in the body were not reinforcing-strip.
strengthened at its smallest diameter by the My invention canbe embodied in a solid cast-iron shoe or in a composite shoe of any variety, and in the drawings I have shown 'the body provided with a plurality of inserts H. l
These locomotive-driver shoes are quite heavy ranging in weight from thirty-five to seventy -iive pounds, and my invention provides a strong and substantial shoe inv which the strengthening means is securely united with the body without the liability of blowholes forming between said means and the body, as occurs when plates are employed forthis purpose. The" hook will not break in handling or in service, andthe bolt-head cannot pull through the body reinforced by the strip. The strips can be made of any metal suitable for the purpose, such as wroughtiron, steel, 'or malleable iron.
What I claim', and desire to secure by Letters Patent, is,-
1.v A -locomotive-driver shoe, comprising a body, a plurality of separated strips embedded in the body at the back thereof, one of said strips having its end bent up to form an attaching-hook.
2.,A locomotive-driver shoe comprising a body, a plurality of separated strips embedded in the body atthe back thereof, said body` having an opening therein shaped to receive the head of the locking-bolt, and one of said strips having an opening to aline with said opening in the body and corresponding in diameter to the smallest diameter of said opening in the body. ,Y 3. A locomotive-driver shoe comprising a body, a plurality of separated strips embedded in the body at the back thereof, said body f having an opening therein shaped to receive the head of the locking-bolt, and one of said Astrips having one -end bent to form the attaching-hook and provided at its other end .withan'opening alining with the opening in the bodyand corresponding in diameter to body.
