Description

Przedmiotem wynalazku jest przyrzad, zabezpieczajacy szyne kolejowa od pelza¬ nia. Przyklad wykonania wynalazku uwi¬ doczniono na rysunku. Fig. 1 przedstawia przyrzad, zalozony na szyne, w widoku podluznym, a fig. 2 —-w widoku zgóry.Przyrzad wedlug wynalazku sklada sie z zakrzywionego haka zelaznego 1 i roz¬ porki drewnianej 2. Hak 1, zalozony na srube zlacza szynowego, obejmuje zakrzy¬ wieniem podklad od spodu. Hak 1 jest przytwierdzony zapomoca sruby do przy¬ legajacych do siebie podkladów, podpiera¬ jacych zlacze szynowe z obu stron styku szyny, i przenosi nacisk sil, wywolujacych pelzanie szyny, na podklad. Rozporki drewniane 2 przenosza nacisk haka 1 z podkladu zahaczonego na dalsze podklady.W zaleznosci od wielkosci sil, wywoluja¬ cych pelzanie, zwieksza sie lub tez zmniej¬ sza sie liczbe podkladów, zwiazanych pod¬ pórkami, tak aby opór warstw podsypki miedzy podkladami byl dostateczny do przeszkodzenia przesuwaniu sie podkladu zahaczonego i tern samem równowazyl si¬ ly, przenoszace sie przez hak 1 na podklad zahaczony, które (niezrównowazone) wy¬ woluja pelzanie szyny. PLThe subject of the invention is a device for securing a railway rail against creep. An exemplary embodiment of the invention is shown in the drawing. Fig. 1 shows the device mounted on the rail in a longitudinal view, and Fig. 2 - in a top view. The example according to the invention consists of a curved iron hook 1 and a wooden spacer 2. Hook 1, mounted on a screw of a rail joint, covers the backing with its curvature. The hook 1 is fastened by means of a bolt to abutting sleepers supporting the rail joint on both sides of the rail contact, and transmits the pressure of the forces causing the rail creep to the sleeper. Wooden struts 2 transfer the pressure of the hook 1 from the fastened sleeper to further sleepers. Depending on the size of the creeping forces, the number of sleepers tied with the supports increases or decreases, so that the resistance of the ballast layers between the supports is sufficient to prevent the displacement of the hooked sleeper, and the tern itself was balanced by the forces transmitted through the hook 1 onto the hooked sleeper, which (unbalanced) cause creep of the rail.

Claims

1. Patent claim. A device for securing a railway rail against creeping, characterized by the terrain consisting of wooden struts 2, placed in the ballast between at least two adjacent railway sleepers, lying on one side of the rail joint, and an iron hook 1, including at one end, a sleeper from the bottom, placed with its ear on the bolt of the rail joint, and fixed with the screw to the adjoining sleepers, supporting the rail joint on both sides of the rail joint.
