Definitions

  • Fig. 1 is an end elevation showing the derail applied to a rail o'l large size, the rail being shown in section.
  • Fig. 2 is an end elevation partly in section of the derail applied to a rail of small cross section.
  • Fig. 3 is a plan of the derail on the rail.
  • Fig. 4% is aview corresponding to Fig. 3, certainparts being shown in section on the line IV-TV, Fig. 2.
  • Fig. 5 is a transverse vertical section through the clamping jaw between its ends
  • Fig. 6 is a horizontal section on the line VI-VI, Fig. 5.
  • the derail of this application differs from that of my said patent in having but one complementary member in place of two sets of clan'iping jaws. This simplifies and lightens the derail and makes its application to the rail easier, but it necessitated the solution of problems incident to the change.
  • the clamping means was subject to little or no twisting strain. With but one clamping means, however, the twisting strain is severe and, where as in the illustrated derail a clamp screw is used, would bend or break the clamp-screw or cause the nut to jam were not provision made to obviate such a result.
  • the invention deals successfully with, this dii'iiculty, and also with the proper location of the clamping means with. respect to the derailing member and with reference to the road-bedabutment, which also must be rightly placed.

  • the sole complementary clamp member of the device is the jaw l.
  • This is of comparatively slender formation being tapered so as to be capable of being readily thrust between the base of the rail and the sub-adjacent ballast or soil with: out special excavation of the latter, and terminates in a hook adapted to embrace or grasp the edge of the base flange oi the rail at the other side of the rail.
  • This jaw mi ght have a rail base bearing parallel to the rail, as in my patented derail, but it is far better to provide it with a rail-clamping contact portion 5 of suitable configuration in horizontal section, as convex, to give a rocking bearing on the rail.
  • the oper' ating means for this complementary clamp member is constituted, in the illustrated derail, by the clamp-screw 6 mounted in and passing freely through the other clamp memher, i. e. the derailingblockmember and having bearings preferably constituted, as in my said patent, by bearing surfaces 7-8 formed respectively in a counter-sink and on the head of the clampscrew so as to permit limited rela tive movement vertically in adjusting the derail to rails of different heights.
  • the clamp-screw 6 mounted in and passing freely through the other clamp memher, i. e. the derailingblockmember and having bearings preferably constituted, as in my said patent, by bearing surfaces 7-8 formed respectively in a counter-sink and on the head of the clampscrew so as to permit limited rela tive movement vertically in adjusting the derail to rails of different heights.
  • the hole through which the clamp screw passes is made substantially larger than the clamp screw and is further enlarged at its inner side as indicated.
  • the particular arrangement illustrated constitutes a ball and socket joint. 7
  • the clamp screw may be provided with suitable means, as a removable collar, for preventing impairment of the thread by scraping back and forth through the hole.
  • the end of the jaw 4 remote from its rail base engaging hook portion is free to swing about the bearing of its rail engaging end on the rail base, since it is located at a considerable distance from any obstructive parts of the-derail block memher which otherw se would have blocked relax the connections: in said" pl'ane endwise of the rail under car wheel impact.
