COMPOUND RAILWAY-BAIL.

of Ohio, have invented certain new and useful Improvements in Compound Railway- Rails, of which the following is a specification.

This invention relates 'to railway rails, and especially to compound rails of that type in which the base and the tread or head are made in separate parts.

By means of this construction the tread can be renewed without disturbing the base part, and therefore the rail is particularly serviceable in street railways, since the tread mentto any great extent, as would sary were the entire rail removed.

The invention includes improved means for fastening the head or tread part on the base.

The invention is illustrated inthe accompanying drawings in which Figure 1 is a cross section showing fishplates on the bottom or base sections. Fig. 2

1s a similar View withoutthe fish-plates.

. Fig. 3' is a section of'a modification, showing I the rail cap held in place without a bolt.

Fig. 4 is a similar view showing a crimp between the flanges of the head and the web, to hold the former in place. Fig. 5 is a side elevation of the construction shown in Fig. 1. Fig. 6 is a side elevation of the construction shown in Figs. 3 and 4.

Referring specifically to the drawings, 7 indicates the base of the rail and 7 the web integral therewith. The top part 7 of this web is slightly enlarged, and is wedge shaped, as shown, and is provided with longitudinal grooves orrecesses 7 along the opposite sides thereof. l

8 indicates the head of the rail which forms thetread, and is removable. This head is provided on its under side with longitudinal flanges 8?, depending on opposite sides,with a wedge shaped space therebetween as indicated at 8 adapted to fit on theupper part of the web. In the form shown in Figs. 1 and 2 the head is connected to the web by :rivets 9 extending through the web and the said flanges. In

Specification of Letters Patent.

Application filed January'Q, 1915. Serial No. 119.

this form, the recesses 7 serve to prevent corrosion between the Web and the flanges, the hollow space formed by the recesses breaking the rust that gathers between said web and flanges when the parts are exposed to dampness and water, and permit easier removal of the head than if the meeting surfaces were continuous. Thebase sections are connected by fishplates 10'on opposite sides of the web, and rivets 11 extending through the fish-plates and the web. By the means disclosed, the head may be removed for renewal, by taking out the rivets 9 and putting a new head in place.

In the form shown in Fig. 4 the rivets are unnecessary, and the head is held onto the web by crimps or bosses 8 which are spotted or forced into the recesses 7 at suitable points along the same, by means of a suitable tool or device, these bosses engaging in the recesses to hold the head on the web without the use of bolts or rivets. To remove the head, the bosses are pried out by a suitabe crow-bar or tool, and the head forced off of the web.

' In either construction, it is unnecessary to remove the bottom part of the rail, and necessary renewal of the heads can be made, as in a street railway, by simply taking up arow of blocks or a narrow strip of the pavement on each side of the rail to give room for work on the fastening devices.

What I claim as new is 1. A compound rail comprising a base having a web integral therewith, the ophead on the web.

8. A compound rail comprising a base having a web thereon provided with longitudinal recesses along opposite sides thereof,

and a head having depending flanges pressed points along the same, to form engaging 13- at intervals into said recesses to form bosses bosses. e V engaglng therem. .7 a In testlmony whereof I affix my slgnature v i. A. compound rall comprlsmg a base 1n presence of'tWo wltnesses.
