摘要： A rail puller for attachment to the end of a rail comprising a top plate having side plates extending downwardly therefrom in a spaced-apart relationship. The bottom surface of the top plate is provided with a centrally disposed guide slot formed therein adapted to receive the tapered end of a wedge. An elongated rod is secured to the inside surface of each of the side plates near the lower end thereof. The puller is installed on a rail by slipping the same over the end of the rail. A wedge is then inserted into the guide slot of the top plate and is driven thereinto to force the elongated rods upwardly into frictional engagement with the underside of the head of the rail. A lifting bracket is provided on the top surface of the top plate and chain hooks are mounted on the exterior surfaces of the side plates to facilitate the connection of the puller to either a hoisting device, a Hy-Railer or the like.

摘要： A rail threader comprising a top plate having side plates extending downwardly from the opposite sides thereof. A vertically disposed plate extends upwardly from the top plate and is adapted to serve as an abutment for the loose rail during the threading operation. The inside surface of one of the side plates has a pair of bars extending inwardly therefrom. When the rail threader has been positioned on a rail, a spacer bar is positioned between one side of the rail and the inside surface of the other side plate. A pair of bolts threadably extend through the other side plate and draw the bars on the first side plate into engagement with one side of the rail. The rail threader is securely held onto the rail by the engagement of the rods and the spacer bar which are urged into engagement with the opposite sides of the rail by the bolts. The loose rail may be threaded into the center of the tracks or threaded outwardly from the center of the tracks through the use of the rail threader.
