LYING AND SECURING RAILS IN ROAD-BEDS OF RAILWAY'S.

SPECIFICATION forming part of Letters Patent No. 299,208, dated May 2'7, 1884i.

Application filed December 17, 1883. (No model.)

.T @ZZ whom, t iii/ty concern:

Be it known that I, .IEANTY DNCHAUD, Sr., of the city and county of San Francisco, and State of California, have invented an Improvement in Laying and Securing Rails in Road-Beds of Railways; and I hereby declare the following to be a f'ull, clear, and exact description thereof.

- now in existence, but is more especially adapted to be used in connection with my safety railwaycar heretofore patented by me, and in which rollers secured by arms tothe car are adaptedto be projected into the groove of the rails to prevent derailment.

In any road a great object to be gained is to prevent the rails from spreading. If this can be done, many accident-s will be averted; but when the rails are to be used with my safety-car it is of prime importance that they shall be strong enough and laid firmly enough to resist the strain of the projected rollers, and to remain accurately in place without spreading, so that the rollers may always find their bearing when projected.

Referring to the accompanying drawings, Figure lis a plan of my rail, showing the clamps for securing them in position. Fig. 2 is a vertical cross-section of same, showing the manner of laying them. Fig. 3 is a plan of a slight ly-modified rail and means for clamping. Fig. i is a cross-section of same. Fig. 5 is a crosssection of a rail resembling the common form now in use, but with my flange formed with it, and showing how it is laid.

A is the rail. This is formed in a T shape, with an outer and inner groove, the rolling surface being preferably flat. It has formed with it on its outer side an upwardly-extend` ing flange, a, anda downwardlyextending fiange, a. In laying the rail its base is iinbedded in the cross-tie B, and its lower flange, a', extends well down into the tie.

C is the brace or clamp. This is of an L shape, and consists of a body of about an equal height with the back of the rail, and an outwardlyextending flange, c. formed a curvilinear bulging lug, d, preferably hollow for the sake of lightness. This clamp is also embedded in the cross-tie, and fits its curved lug d into the outer groove of the rail. Bolts e pass through the clamp and rail, one at the top through the upper flange of the rail, and one at the center through the lug. The head of this latter bolt is to be countersunk, as shown, to preserve a smooth surface on the inner groove, to adapt it for use in connection with my safety railway-car. A spike, b, is driven through the flange c of the clamp into the cross-tie. At the joint of two rails the clamp C is made sufficiently long to brace both rails.

By embedding both rails and clamps in the ties, great stability is given them, andby clamping them together thus securely they are notliable to spread, but will remain firm and even. The embedded flange of the rail of itself gives great firmness. This rail, it will be seen, can be reversed.

A modification of this rail, made for the sake of economy and to preserve the style now in use as nearly as possible, is shown in Figs. 3 and 4. I-Iere the upper flange, a., is omitted, the rail being provided with a lower flange only, which, together with the base of the rail, is embedded, as in the first rail, in the crossties. The top of the rail is of the common shape, and the clamp is made to conform to the modified rail by reducing the height of its body. It is secured to the rail by a single central bolt; but in case it should be found impraeticableto change entirely the present system of rails and means for securing them, I show in Fig. 5 but a slight change from the present rail. This has the addition of the iiange a embedded in the tie, as is also the base of the rail. The ordinary spikes secure it to the cross-ties, and the fish-plates are here shown as lying on the inside, to keep the outer groove smooth in case it should be desired to use the rail in connection with any safety-car On its face is IOO having rollers adapted to t the outer groove.

The clamps or braces shown may be made of Wood as well as iron, thus making them moreeconomical and equally as strong.

This improvement'in laying and securing the rails Will give a great economy in crossties, because they may be put at Wider distances and still give solidity to the rails, as the latter are embedded in them.

I am aware that prior to my application railroad-rails constructed with iianges adapted to fit grooves formed in the cross-ties had been made, and such I do not claim; but

What I dol claim, and desire to secure by Letters Patent, is-

l. In the road-bed of a railway having crossties B, the rail A, having a flange, a', the base .of said rail and its ange being embedded in the crossltie, in combination with the L-shaped brace or clamp O, having a curvilinear or bulging face, d, fitting the outer groove of the rail, said clamp being bolted to the. rail7 and having its base embedded in the cross-tie and spiked thereto, substantially as herein described.

2. In the road bed of a railway having cross ties B, the rail A, having the lateral flanges a a", and side grooves, in combination with the L-shaped clamp or brace having a curvilinear or bulging lug d on its face, tting the outer groove of the rail; anda means forsecuring the clamp to the rail and the rail and clamp to the cross-tie, substantially as herein described. p

In Witness whereof I have hereunto set my hand.

Vitnesses:

WM. F. BOOTH, C. DNOHAUD.
