JOHN OLLOMAN, OF EAST PALESTINE, OHIO.

METALLIC CROSS-TIE AND CLAMP.

.ePECIFICATION forming part of Letters Patent No. 718,952, dated January 20, 1903.

Application filed April 25, 1902.

To all whom it may concern:

Be it known that I, JOHN OLLOMAN, a citizen of the United States, residing at East Pal-- estine, in the county of Columbiana and State of Ohio, have invented a new and useful improvement in metallic cross-ties and a fastener or clamp to fasten rails of railroads, trolley-roads, and incline-roads, 850., to me tallic cross-ties, of which the following is a specification.

My invention relates to metallic cross-ties for railroads, trolley-roads, incline-roads,&c., with clamp-fasteners forming jaws or clamps, one of which may be permanently fastened to each end of the cross-tie or the tie made with one jaw or clamp on each end of the cross-tie, forming a part of the tie or of the same piece of metal, and the other jaws or clamps adjusted by means of m ortises or holes in the cross-tie, through which the clamp or fastener is inserted and connected or adjust ed and held by means of a retaining key or wedge, which is made with two prongs or tines, so as to be spread, or one prong bent so as to hold it in position permanently. The cross-tie may be box-shaped, flat, channeliron or T shaped, and the clamps may all be adjustable, or the cross-tie may have one or two permanent clamps or fasteners.

My invention also relates to the clamp or fastener, which is adjustable and applied by means of mortises or holes in the cross-ties, through which the clamp or fastener is connected and held in position by means of a retaining key or wedge or a nut or other device.

I attain these objects by means of the mechanism illustrated in the accompanying drawings, of which- Figure 1 is a side View and partial vertical section through the center of the cross-tie. Fig. 2 is a perspective view of the cross-tie and rail and one clamp or fastener in position or place. Fig. 3 is a perspective of the clamp or fastener.

Similar letters refer to similar parts throughout the several views.

In Fig. 1, A represents a box-shaped crosstie. B represents a railroad iron or rail. 0 is the clamp or fastener. a a a c are the mortises or holes in the cross-tie. c c are slotmortises in the clamps or fasteners, through Serial No. 104,620. (No model.)

which the retaining-key is driven. cross-tie broken off between rails.

In Fig. 2, A-is the cross-tie. B is the rail. 0 is the clamp or fastener in position. D is the pronged wedge or retaining-key. a a are the mortises or holes in the cross-tie.

In Fig. 3, (J is the clamp. e is the jaw or claw, which comes down on the flange of the rail. 0 is the slot-mortise in the clamp or fastener, which must be made to extend a little below the surface of the tie when in position.

The cross-ties may be made box shape, T shape, flat, or channel-iron. I makethe Inortises or holes a a a a through the upper flange on T-shaped cross-ties or channel-iron crossties and through flat cross-ties and through the upper side of box-shaped cross-ties, as shown in Fig. 2, where a box-tie is represented by letter A. I make the mortises or holes a a a a so that the flange of the rail when in position on the cross-tie is a little over the mortise into which the clamp or fastener is first inserted in adjusting it, as shown in Fig. 1. A few inches back another mortise a is made, through which the end of the clamp, with the slot-mortise c, is brought up, as shown in Fig. 1.

Ametallic cross-tie withapermanent clamp and brace is also intended to be used in connection with this adjustable clamp-fastener 0n the outside of the outside rail at curves on railroads, which will keep the rail from turning, the balance of the cross-tie to be mortised for the adjustable clamp-fastener.

The clamp O in Fig. 3 I make of iron or steel and in size to suit the dimensions of the rail used and the thickness of the metal of the cross-tie at the point where the holes or mortises are made in the cross-tie. The jaw or claw e I make long enough to take a firm hold on the flange of the rail, as shown in Fig. 2, and the jaw or claw e on clamps or fasteners on the outside of the outer rail at curves in railroads I make long enough to come up against the side of the rail and extend nearly to the top of the rail to form a brace to support the rail and assist the inside clamp or fastener in keeping the rail from turning, thereby making the rail on a curve doubly secure. In such case I adjust such g is the outside clamp-fastener before the rail is put ICO in position on the tie, or a tie with a permanent clamp or fastener for the outside of the outer rail may be used and will be of great advantage, especially where there is a sharp curve in the line of the railroad. The body portion of my improved fastener is approximately U-shaped and has one of its ends provided with a slot 0 adapted to receive the retaining key or wedge D. I make the mortise c to extend a little below the surface of the cross-tie when the clamp isin position, so the jaw or claw 6 can be firmly set on the flange of the rail by the driving of the key or wedge and to take up any wearing at the point of bearing of the rail and tie or other loosening by driving the retaining'key farther in or through the slot-mortise.

The clamp or fastener is adjusted by inserting the mortised end through the mortise a at the flange of the rail and bringing it up through the other mortise a back from the rail, which mortise must be the same distance from the mortise at the rail as the angles of the clamp are from each other, giving a little room for adjusting, as shown at Fig. 1. The pronged key or wedge D is then inserted in the slot mortise o and driven tight. One prong of the key or wedge D is then bent back to hold it in position, as shown in Fig. l

2. The driving of the key or wedge D will bring the jaw or claw e firmly on the flange of the rail and make a complete and secure fastener, holding the rail firmly and secure and avoids the use of nuts and bolts.

If preferred, I make the clamp C of round iron or steel and make the mortises or holes a a. a a, circular or round in the cross-tie. I

also put on a thread or screw for the use of nuts to be used instead of the retaining-key D; but I prefer the key or wedge D even in round iron clamps, and my invention is superior because I make use of the pronged key or wedge D, which cannot work out or become loose and can be adjusted in much less time than nuts and bolts, and therefore my invention is an improvement on or is superior to all other fasteners in that I use no nuts or bolts.

I am aware that metallic cross-ties with adjustable clamps or fasteners have been made prior to my invention, and I do not claim the combination in its broadest sense; but

What I do claim as my invention, and desire to secure by Letters Patent, is-

In a device of the type set forth, the combination with the rail, and the tie, said tie having a pair of openings formed in its upper wall at each side of the rail; of approximately U-shaped rail-fasteners, having their body portions arranged within the tie, and normally engaging the inner face of the top wall of the tie, and having their ends projecting through the said apertures, one end of each fastener having an aperture therein, a claw formed integral with the other end of the said clamps, andadapted to engage the base of the rails, and retaining keys arranged in the apertures of the said fasteners and engaging the outer face of the upper wall of the tie.
