RAILWAY-RAIL FASTENER.

Application led January 6, 1922. Serial No. 527,468.

T0 all fui/0771, tana-y concern.'

Be it known that l, Airuno Davies PRES- TON, a subject of the King of Great Britain, and a resident of Claremont, VVesternAustralia, Australia, have invented' a new and Improved Railway-Rail Fastener, of which the following is a full, clear, and exact description,

This invention relates to improvements in railway rail fasteners, an object of the invention being to provide an improved tie plate, clamp and spike which cooperate to securely fasten a rail in place.

An additional object is to provide a fastener which will tend to brace the rail against lateral and vertical strains set up by a passing train and permit the variation of gauge and adjustment which may be required from time to time.

Another object is to provide a fastener of this character, which'will prevent the timbers from being out into and. being destroyed by Contact with the tie plate, or in other words, to provide a tie plate which will cause the tie to be evenly compressed under-*the weight of train loads.

Still another object is to provide a railway railfastener in which a rail may be removed and replaced without pulling the spikes.

` Further objects are to provide a device of this character, which will be simple and practical in construction, strong, durable and ellicient in use, and which can be economically manufactured and installed.

With these and other objects in view, the invention consists of certain novel features of construction and combinations and ar-v rangements of parts, as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings:

Figure l is a view in transverse section on the staggered line l-l of Figure 3 through a railway rail showing the rail supported in applied position by my improved fastening devices;

Figure 2 is a view in section on the line 2-2 of Figure l;

Figure 3 'is a top plan view of Figures l and 2;

Figure 4l is a fragmentary sectional view illustrating the manner of driving the spikes into the ties; and

Figure 5 is a view in transverse section showing my improved fastening devices retaining a fishplate in position.

Referring in detail to the drawings, il represents a conventional type of railway tie. A rail 2 is supported above the tie upon a tie plate 3. llt will be noted that the tie plate includes a flat under face bearing` against the tie and serving to evenly colnpress the same under the load of a passing train. The flat face of the tie plate prevents injury to the tie.

The tie plate includes flanged side edges such as l for a purpose which will hereinafter appear. The tie plate is secured to the tie by means of my improved spikes designated by the reference numeral 5. The spikes are round in cross section and include adjacent their upper ends tapered shoulders such as 6, which fit into tapered openings 7 in the tie plate holding the tie plate against movement and coupling` the saine firmly to the tie. Above the shoulders G, the spikes include a screw threaded portion 8 and at their extreme upper ends are square in cross section, as indicated at o 9 so that they may be conveniently gripped by a Spanner wrench.

Clamping plates l0 include base flanges ll abutting against the flanges e of the tie plate and beveled clamping flanges l2 which overliel the base flange 18 of the rail 2. The clamping members are bored to receive the reduced upper ends of the spikes 5 and the clamping flange 12 of one member preferably overlies the base fla-nge l1 of an adjacent member. The flanges are held in place by gaskets lll and nuts 15 screwed onto the upper end of the spikes 5.

lt will be readily seen that lateral strains on the rail 2 are transmitted directly to the flanges 4f of the tie plate 3 through the nu:- diuiu of the clamps 10. llt will also be anw parent that the nuts and gaskets may be removed permitting removal of the cl inping plates and rail without disturbingthe position of the spikes 5.

The peculiar conformation of the upper ends of the spikes 5 permits them to be driven home by the use of a suitable tool without injuring their threaded portion. A drivingcap such as 16 shown in Figure t, may be applied to the upper end of the spikes and will bear against the upper squared ends of the spikes and against the tapered shoulders 6 thereby allowing them to be driven home without injuring the screw threaded portion of the same. The spike holes in the ties arepreferably drilled at the mill so that there is no danger ofrsplitting the ties byadriving home the spikes. lNhen it is necessary to remove the spikes they may be easily driven through intothe ballast and new spokes of slightly larger size inserted. i

In Figure 5, I have merely illustrated a slight modification which shows another use of the clamps 10. The clamps in thisinstance are used to securely clamp the base flanges 17 of fishpiates 18 at the junction of two rails. The clamps 1 are supported upon the iianges 4 of the tie plate 3 when used for holding` the fishplates and an additional `joint tie plate 19 of greater width than the plate 3 is used to support the plate 3 and is provided with lateral flanges 20 bracing the plate 3 against lateral strain. It will of course be necessary to use'somewhat longer spikes in connection with this form Vof fastener.

Although I have illustrated certain of the preferred embodiments of the invention, it will be evident that various slight changes and alterations might be made in the general form and arrangement of the parts described without departing from the invention, and hence I do not wish to limit myself to the precise details set forth, but shall consider myself at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of the appended claims.

`I claim:

1. In a railway rail fastener, the combination with a tie plate and a rail supported thereon, of clamping members on the plate including fianges overlying the rail base and eachother.

2. In a railway rail fastener, the combination with a tie, a tie plate and a rail supthe tie and including tapered `shoulders lo `cated above the tie, said tie plate having recesses therein receiving the spikes, the walls of said recesses being tapered to seat firmly on said shoulders, and rail engaging means -retained against movement on the plate.

3. In railway rail fastener, the combination with a tie, a tie plate and a rail supported on the tie plate, of spikes driven into the tie and including tapered shoulders located above the tie, said tie plate having recesses therein receiving the spikes, the walls of said recesses being tapered to seat firmly on said shoulders, and rail engaging means retained against movement on the plate, said rail engaging means comprising clamping members, sidelanges on the plate cooperating withtherail base to prevent lateral movement of the clamping members, said clamping members including overlapping flanges. i

4. In a railway `rail. fastener, the combination with a tie, a tie plate and 4a lrail supportedy on the tie plate, of spikes driven into the tie and including taperedshoulders `located above the tie, saidtie plate having re cesses therein receiving `the spikes, the walls of said' recesses being tapered to seat rmly on said shoulders, rail engaging' means retained against movement on the plate, said rail engaging means comprising clamping members, side flanges on the plate cooperat-V ing with the rail base to prevent lateral movement of the clamping members, said clamping members including overlappingI flanges, said clamping members being bored to receive thespikes, and nuts screwed-onto the upper ends of the spikes retaining said members in clamping relation tol therrail and to eachother.
