. Railroad record, and journal of commerce, banking, manufactures and statistics . down the edges of thebase of the rails, in the usual manner; and the heads ofthese spikes are covered by the plates C and D, in which re-cesses are provided frr them in such a manner as to preventthe possibility of the spikes being withdrawn while the platesare in their place. The plates C and D, constructed, and applied, andtongued together, by the tongues passing through the rails,and secured by keys, as described, clamp and lock the railstogether, both vertically and laterally, in the firmest possi-ble manner, so that neither can move without the other. One of the advantages this invention claims over allothers, is the introduction of two peculiarly constructedside-clamping plates, in combination with a correspondingchair. The inside plate has two strong horizontal tongues,with vertical slot? in the ends of the rails, and correspond-ing ones in the outside plate. By driving through two keys,they clamp and lock the plates firmly together, so that nei-her can move without the Another great advantage is, the allowance which is madfor expansion and contraction between the tongues anslots in the rails, so that they can not shove together, as inthe present mode of fastening them—each joint acting in-dependent of the other. This mode of securing rails maybe considered past improvement. It will be seen that on «part assists and takes tho strain off the other, in such a man -ner that there is no particular strain on any part of sthjoint, which must wear smooth and make a perfectly afe«road, thereby doing away with the breaking of rails, wheels,and axles, preventing the loss of life and destruction oproperty, and saving at ieast fifty per cent, on the wear othe rolling stock of the road.
