O. LIEDER RAIL FASTENING Filed July 29) 1924 Patented June 9, 1925.
UNITED STATES PATENT OFFICE.
OTTO LIEDER, OF DRESDEN, GERMIANY.
RAIL FASTENING.
Application filed. July 29,
that the vertical and horizontal forces are taken up, respectively, by special keys driven between the upper head of the hook, which is movably attached to the tie plate, and the base of the rail, and between the stem of the hook and one shoulder of the plate.
In the known types of similar rail fastenings the keys are firmly connected and,
i 20 therefore, cannot be adjusted to the varying wear of theforce-transmitting surfaces, the said wear and tear being caused by forces working in different directions. By separating the keys so as to cause one of them to transmit the vertical force and the other one to transmit the horizontal force, each of them may be tightened individually and separately from the other, in accordance with the amount of wear, whereby the rail is much more securely fastened to the plate.
The drawing illustrates one modification of the invention and represents a longitudinal section through the tie plate.
1 is the wooden railroad tie, to which is fastened the tie plate 2, being provided with bores 3 for fastening purposes. 4 are double-headed hooks, movably attached togrooves 5 of the tie plate. 6 is the base of the rail. 7 are keys intended to take up the vertical force by causing the lower sur- 1924. Serial No. 728,884.
face 7 of the hook 4 to act as key surface. 8 are keys intended for taking up the horizontally acting forces by causing the sidev surface 8 to act as key surface.
9 is the stem of the hook 4, and 10 are shoulders of the plate.
The dotted line of the double-headed hooks or clamps indicates the possibility of adjustment of the gauge by using keys of varying size.
ing is as follows:
The mode of operation of the rail fasten- The vertical and horizontal lateral forces *are taken up by a separate key 7 and 8, re
spectively. lVhen the rail gets loose in vertical direction, the keys 7 are tightened, while any loosening in horizontal direction requires tightening of the keys 8. This independence of the keys from eachother permits permanent, firm fastening of the rails to the tie plate.
The tie plates may also be attached to metal ties the tops of which may be used for the reception of the fastening means.
I claim Rail fastenings characterized by a tie plate provided with openings, double-headed hooks in said openings, and keys cooperating with the hooks to take up the ver tical and horizontal forces, the said keys being driven between the upper heads of the hooks and the base of the rail and between the stem of the hooks the plate.
and one shoulder of In testimony whereof I have afiixed my slgnature in presence of two witnesses.
OTTO LIEDER.
