' 5 of Canada, have invented new and useful Improvements in Railway-Spike Holders, of which the following is a 'full, clear, and exact description. i

This invention relates to improvements 10 in railway spike holders, and the object-is to provide a simple and effective device for preventing the loosening of railway spikes. Itis well known that this loosening is due mainly to two forces. The first ofthese is the bending of the rail as the wheelspass over the unsupported portion between the ties, and the second is the cutting o-fthe rail into the tie so that the rail drops away from the heads of the spikes.v There is.in

addition to these the everpresent factor of vibration, and also, in certain countries, of frost. This invention aims to overcome the action of these forces by placing a solid member between the heads of the spikes and the under side of the rail head, so that as the rail gradually sinks the spikes will be forced down and thus hold the rail tightly to the ties. In the drawings which illustrate this invention:1*igure 1 is a transverse sectional view of a rail showing the spike holder in position thereon. Fig. 2 is a side elevation of the device. Fig. 3 is a View similar to Fig. 1, but showing a slight modification. Fig. 4 is a plan view of the device.

Referring to the drawings, 5 designates a'rail of any suitable cross-section, 6 the tie on which it rests and 7 the spikes holding the rail to the tie. The invention consists of a short bar 8, of metal, rolled or otherwise formed to the cross-sectionshown on the right hand side of Fig. 1, this section being taken on the line BB of Fi 2;2'. 6., through the body of the bar. This bar is made in various sizesto fit thevarious rail sizes, and fits snugly between the head 9 and flange or base 10 of the rail. On the lower face of the bar 8 is a groove 11 shaped to receive the head 12 of the spike 7. The

outer wall of the groove is formed by a flange 13 of such depth that it is approximately in line with the lower face of the rail base. At intervals along the bar, recesses 14 are formed for the reception of the nuts and heads of the bolts 15, as shown in the left hand side of Fig. 1, the section place by means of the bolt '15.

being taken on the line AA of Fig. 2. The bolt 15 passes through the bars 8 and through theaperture 16 in the web 17 of the rail and attaches the bars to the rail. The inner side of the bar which abuts the web of the rail is provided with a groove 18, such as1 is usually found in fish plates and the li (e.

In the modification shown in Fig. 3 the bars 8 are not recessed for the bolt heads andnuts as the nuts lie a ainst the outer sloping faces of the bars an the bolts themselves pass in an inclined direction through lines in Fig. 42. These latter constructions have the advantage that they do not weaken the rail web by necessitating'bolt apertures therethrough at frequent intervals, while, at the same time, they hold the bars 8 securely in place so that the web of the rail is supported thereby fully as much as in the form first described.

In order that the railways track inspectors may readily detect spikes which are broken I provide slots 19 out angular-1y through the flange 13 of the bar 8 through which the back and one side of the spike may be seen, as shown in Figs. 2 and 4. By cutting the slots angularly two sides of the spike are exposed, whereas if the slots were transverse only one side would be exposed unless the slots were of considerable size. These slots are preferably only a part of the depth of the flange 13, so that the flange retains a good hold on the spike heads, as is best seen in Fig. 2, this hold being necessary to prevent independent lateral movement of the rail and spikes. In the manufacture, this bar 8 is preferably rolled to standard dimensions, and the recesses 14 and bolt apertures formed therein as desired. For ordinary use the bars arecut into short sections so as to nearly extend across the ties. Longer sections may, however, be made and used as fish plates.

- In laying a track, the rails are spiked '60,. the ties in the usual manner. Short sections of the bar 8, each having, preferably, a, single bolt aperture are placed on opposite.

sides of the rail and clamped tightly in As the groove 11 is formed throughout the length slots 19 in the bar flanges.

the spikes down with the rail as the latter cuts into the tie, so that the rail is held tightly against the ties, and vibration thus materially reduced. As these bars are placed on opposite sides of the rail and bolted together, they form a tie between the spikes on both sides of the rail, thus hold-' ing the rail from creeping laterally and drawing the spikes, as occurs at curves in the track. This device will alsolsupport and relieve the web of the rail'of much strain, especially at curves. The device may be used at every tie, or only on curves, as desired.

Havin declare t at what I claim is 1. In a railway spike holder, a-substantially triangular bar having one side thereofformed to abut the web of a rail, and the second thereof formed to abut the flange of the rail, said bar having a groove formed in the second side thereof to receive spike thus described my invention, 1

heads, an integral flange forming the outer wall of said groove extending belowthe body of the bar to approximately the level v of the lower face of the rail flange, the third side on said bar being provided with recesscs and apertures for the reception of attaching bolts.

2. In a railway spike holder, the combination with a railway rail and the spikes securing same of a substantially triangular bar, located on each side of said rail, said bars being shaped to fit snugly between the flange web and underside of the head of the rail, and having a groove formed therein for the reception of the spike heads, and bolts connecting said bars through the rail.

' .3..In a railway spike holder, a bar located on each side of the rail and extending 7 from the underside of the railhead to the spike head, flanges integral with said bars, positioned to prevent lateral movement of the spikes, and bolts connecting said bars through the rail.

In witness whereof I have hereunto set my hand in the presence of two witnesses.
