1510224 Railway rail fastening clip PANDROL Ltd 26 Aug 1976 [7 Nov 1975] 46281/75 Heading E1G A railway rail fastening clip comprises a rod of resilient metal with a length less than 18 times its thickness which has been bent so as to have, progressing from one end of the rod to the other end, a first portion I which starts at one end of the rod and is a straight or nearly straight leg, a second portion 2, a third portion 3, a fourth portion 4, and a fifth portion 5 which ends at the other end of the rod. These portions are such that when the clip is in a particular position the lowermost points on the third and fifth portions 10, 11 are in the same horizontal plane as one another; the second portion proceeding from the first portion to the third portion, has a rising part 2A followed by a falling part 2B; when the clip is viewed from above, the third and fifth portions appear to be on opposite sides of the axis of the first portion; and when the clip is viewed in a horizontal direction parallel to a straight line passing through the lowermost points on the opposite ends of the first portion 14, 15 the rising part 2A of the second portion is inclined to the horizontal by, everywhere, less than 45‹.

专利说明:

one
The invention relates to the field of the upper structure of a railway, in particular to a rail fastening device, in particular, to its elastic terminal.
The purpose of the invention is economy1 "1 material.
FIG. 1 shows a terminal, front view in FIG. 2 - the same, side view; in fig. 3 - the same plan view.
The elastic clamp for rail fastening is made by bending the ingothole - a rod of a certain length and diameter. The terminal contains a straight section 1 (Fig. 1) for its installation in a horizontal element of the arbor base. Behind this section there are successively bent sections 2-5, forming elastic
62
terminal. Plot 2 of the terminal has an upward retraction from plot 1, and then lowering to portion 3 of part A and B (Fig. 2). Sections 3 and 5 are located on opposite sides of the axis of section 1 (Fig. 3), with the lower points 6 and 7 (Fig. 2) of sections 3 and 5 located in the same plane A, and the lower points of line 8 of section 1
placed below the plane A (Fig. 2).
The length of the curved rod, forming an elastic terminal (Fig. 1-3), exceeds its diameter in the range from 12 to 18 times, and the lifting
Part A of section 2 of the terminal forms an angle with the horizontal plane (less, (Fig. 2).
After being mounted in the rail fastening unit, the elastic terminal provides the necessary pressing of the rail to the base.
