FASTENING AND SUPPORT FOR RAILWAY-RAILS.

SPECIFICATION forming part of Letters Patent No. 462,080, dated October 2'7, 1891.

Application filed June 5, 1891. Serial No. 395,220. (No model.)

To all whom, it may concern:

Be it known that I, J OHANNES GRIMME, engineer, a subject of the King of Prussia and German Emperor, residing at Bochum, in the Kingdom of Prussia, German Empire, have invented certain new and useful Improvements in Fastenings and Supports for Railway-Rails; and I do hereby declare the following to bea full, clear, and exact description of the inven- [0 tion, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to an improved construction of the chairs or sleepers and fishplatesofthepermanentwayof railways,whereby the fish-plates also constitute the support forthe rail, while atthe same time they operate in conjunction with separate chairs, baseplates, or sleepers in such manner as to automatically apply an increased grip to the rail when this is loaded, so that the fish-bolts are relieved of strain when the load is passing over the joint. The new arrangementis illustrated in the accompanying drawings, in which- Figure 1 shows the arrangement of the fast ening and of the support in avertical section after the line y y in Fig. 3. Fig 2 is a vertical section after the line 2 ,2 in Fig. Fig. 3 is a side View with a vertical section through 0 the line $113 of Fig. 1. Fig. 4 shows in a horizontal plan the new arrangement for the whole railway-track by using the new baseplates as a chair extending over two crosssleepers, between which the joint of the rails 5 is placed. Fig. 5 shows, also in a horizontal plan, the same arrangement by using the base-plate as a chair, sitting only on one cross-sleeper, over which the joint of the rail is placed. Fig. 6 shows the same arrange- 0 ment in case the base-plate is used as alongitudinal sleeper.

For reaching the purpose aforesaid in all these cases the fish-plates L L are formed angular with Vertical portions which fit 5 against the webs of the rails S S between the head and the base, and a horizontal portion terminating in an inclined end face, so that the inclined end faces of the two fishplates L L form together a wedge, which fits against the correspondingly inclined side faces 0 (Z of a trough-shaped base-plate, chair,

or sleeper B, shaped in the form a cf 0 9 cl h N), so that on exerting a downward pressure upon the horizontal limbs of the fish-plates L L by means of screw-bolts S 5*, screwing them to the bottom 9 of the base or sleeper,

a wedging action is produced, whereby their vertical limbs are pressed against the web of the rail independently of the pressure exerted by the ordinary fish-bolts S S passing the fish-plates and rail. Furthermore, when the rail is loaded by a passing train the downward pressure exerted thereby still further increases such wedging action, and consequently also the inward pressure or grip of the vertical limbs of the fish-plates, so that the fish-plates will then be relieved of strain instead of having increased strain put upon them, as in the case of ordinary fish-plates, where the load of a passing train causes the head of' the rail to exercise a downward wedging action on the fish-plates, tending to force these outward away from each other.

The force applied to the fish-plates forproducing the gripping action in the above-described construction is not limited to the comparatively small surfaces represented by the heads and nuts of the fish-bolts, as in the case of ordinary fish-plates, but extends along the entire surface of the inclined faces of the lishplates, so that the strain at any one point is considerably less than in the first-named case, and consequently the wear and tear are also decreased. The trough of the base-plate, chair, or sleeper B must of course be of such a depth that the base of the rail will always be out of contact with the bottom of the trough when loaded. The base-plate, chair, or sleeper B may otherwise be constructed in various ways for the purposes of the inven- 0 tion; but by preference the two sides of the trough are made of a hollow bridge form of sufficient strength to withstand the lateral wedging strain put upon them by the fishplates. 5

When used as a chair, as shown in Figs. at and 5, the base-plate can be either made of such a length as to extend over two crosssleepers, to which it is fixed by screw-bolts or spikes passing through lugs or flanges on the ICC chair, (see Fig. 4,) or it maybe only of such a length as to be, carried by a single crosssleeper. (See Fig. 5.) When used as a longitudinal sleeper, as it is shown in Fig. 6, it is made in convenient lengths, bolted or otherwise secured together. In this case intermediate pairs of the angular fish-plates may be provided for supporting the rails between the joints, but Without fish-bolts passing a through them, the requisite grip being atforded by the fixing-bolts passing through the bottom of the trough.

It Will be seen that in the abovedescribed fastening the screw-bolts securing the fishplates, respectively, to the rails and to the chair, base-plate, or sleeper need only be screwed up to such an extent as to hold the several parts together, the required grip being effected entirely by the pressure of the passing train.

Having now particularly described and as certain ed the nature of my said invention and J OHANNES GRIMME.
