- Specification of Letters Patent.

Patented oct. 14,1919.

Application filed May 2'1 1917.' Serial No. 169,823. Renewed March 13, 1919. Serial No. 282.496.

To all whom it may concern: a

Be it known that I, J OHN F- LYDoN, a c1t1-.

'zen of the United States, residing at Kansas City, in the county of Jackson and State. of Missouri, have invented certain new and useful Improvements in Anticreeping Means for Railway-Rails, of which the followlng is a specification, reference being hadto theaccompanylng drawings. 7

An object of the invention is to prevent undue creeping of railway rails lengthwlse of the road-bed.

Another object of the invention is to prevent the ends from crowding or ramming each other.

Other objects and advantages of the invention will be set forth in the ensuing description.

The drawings show one embodiment of the invention'in practice.

Figure 1 is a perspective View showing a fragment of a rail-way rail and showing the anti-creeping means in use thereon.

Fig. 2 is a similar view showing a modified form of certain parts.

Fig, 3 is a perspective View showing the ends of two rails at a joint.

Fig. 4 is a similar view of a fish-plate.

Fig. 5 is a side elevation of the parts shown in Fig. 1.

Fig. 6 is an enlarged sectional view taken on the line 66 of Fig. 5.

Like characters of reference designate like parts in all the figures.

The fish-plate 10, shown separately in Fig. 4, consists of the usual vertical portion 11 adapted tolie flatly against the web 12 of the rail 13, the lower edge of this Vertical portion being integrally flanged outward as at l4-so as to rest on the laterally-projecting half of the rail-base 15.

In joining two rails 13, a fish-plate 10 is placed on each side of the rails at a jolnt 16, as best shown in Fig. 6, and bolts 17 pass through the vertical portions 11 of said fishplates and through the webs 12.0f the rails; these bolts being provided with nuts 18 which are screwed up tightly to clamp said fish-plates and rails together.

In many types of the fish-plates 10 their flanges 14 project laterally beyond the edges of the rail-bases l5, and are notched as at 20 so that the spikes 21 commonly used may pass down through said notches into the ties 22rand thereby preventthe fish-plates from creeping lengthwise of the track.

The construction and arrangement of parts just described has been in use for many years; but a. serious objection to it is that, since the fish-plates 10 are held positively against creeping movement by the spikes 21,

.the bolts 17 are in turn relied upon solely to prevent creeping movement of the rails 13 lengthwise of the road-bed.

These bolts 17 are also relied upon to prevent the ends of the rails at a joint 16 from ramming each other.

In overcoming these difliculties, the invention provides upon each rail 13 a suitable rigid stop or projection, and also provides in or upon each fish-plate 10 a notch or other form of recess into which said projection 6X tends in a direction at right angles to the line of length of the rails.

Within the meaning and intent of the invention, the projection may be located upon any suitable part of the rail 13 and be secured to the rail in any approved manner; and the notch or recess may be located on any part of the fish-plate 10.

A practical way of carrying out the invention, and possibly a preferable way, is to cut a notch 23 in the outer edge of the flange 14 0f the fish-plate 10, in the same manner as the notch 20 aforesaid is commonly cut for the spikes 21, and then set straddle of the edges of the rail base 15 the hooked blocks 24 in position to project upward through said notches 23,

These blocks 24 are clamped tightly against movement on the rail-bases 15 by bolts 25, which pass through the depending portions 26 of said blocks below the rails 13 and are provided with nuts 27.

The engagement of these blocks 24 with the notches 23 of the fish-plates 10 holds the rail 13 against creeping movement, except the limited movement necessary for expansion and contraction of the rails, which may be provided for by making the blocks a little short of the length of the notches in the direction of the length of the rails.

The notches 23 may be located between two ties22, as shown in Fig. 2; but since it might be considered bad practice to thus weaken the fish-plate between its supported ends it is deemed preferable to extend each end of the fish-plate entirely over and be yond its respective tie 22 and form said notches in the extended ends of the fishplate, as shown in Fig. 1.

The blocks 24 may be so adjusted on the rail bases 15 as to abut the ends of" their notches 23 before the abutment of the rail ends at a joint 16, and thus prevent said rails from being battered out of shape.

Having thus described the invention, I claim In an anti-creeping means for railway rails, the combination with the abutting ends of a pair of rails, of fislrplates applied to the sides of the rails and provided at their lower edges with outstanding flanges extending over the rail bases and having corresponding notches in the edge portions thereof, fastening members securing the fish-plates to the rails, a pair of opposed hooked blocks fitted in the notches of the fislrplates and gripping the edges of the rails, said hooked blocks being formed With depending portions, and a transversely extending clamping bolt connecting the depending portions of the hooked blocks and tending to rotate the hooked blocks and cause them to tightly grip the rails, said blocks engaging the notches in the fish plates to prevent creeping of the rails.
