To all 107mm 2'!) may concern.

Be itknown thatI, CHARLES KNEL a citizen of the "United States, residing at Oakmont, in the county of Allegheny and State of Pennsylvania, have invented new and useful Improvements in Rail Anchors, of which the following is a specification.

My invention relates to rail anchors andis to provide asimple improved device for preventing the creeping of railway rails relatively to the ties.

Referring to the accompanying drawings, Fig. 1 is a top plan View of a fragment of a rail with my anchor applied thereto; Fig. 2 a cross section on the line IIII of Fig. 1; Fig. 3, a side view of my anchor applied to the rail shown in end elevation; Fig. A an elevation of the locking key or latch for connecting the anchor to the rail; Fig. 5, a top plan view of my rail anchor withoutthe said key or latch, andv Fig. 6, a side elevation showing, my rail anchor complete.

' Fig. 7 is a perspective View of one end of my rail anchor showing a modification.

My rail anchor comprises a metal angle bar 1 and the locking key orlatch 2. The angle bar has the Vertical flange 3 and the horizontal flange 4:. The flange 1 is cut away from the flange 3 for a short distance, as shown in Fig. 1, and the part 5 thus cut away from the flange 3 is turned upwardly and back over the adjacent portion of the flange l to form the book 6 inwhich the flange 7 of the rail 8' is seated, the bottom of the said flange 7 and of the rail flangeS being seated on the upper surface of the flange 1. The hook 6 fits the flange 7 snugly as shown in Fig. 3. At the outer edge of the rail flange 8 I provide in the flange a: the hole or slot 9 substantially parallel with said rail flange 8.

The key 2 has a base portion 10 resting on top of the flange 4 and also a downward extension extending through the slot 9.

his extension has the neck portion 11 which. is rounded so as to rotate in the rounded end of the slot 9 next to the flange Below the neck portion 11 the extension has alateral projection 12 which is adapted to pass through the slot 9 and to engage the lower face of the. flange 3 when the key has been turned ninety degrees so as to bring the lateral projection 12 against the inner face of the flange 3. The upper portion of the key above the base 10 forms a curve or a hook 13 which preferably lies in the Serial No. 675,081.

plane of the lateral projection 12. This key is preferably made :of malleable steel siderable friction.

In assembling the anchor upon the rail the anchor without the key is first placed beneath the rail with the hook 6 embracing the outer'edge of the flange 7 and the base of the rail resting on the flange 1. The key is then inserted through the slot 9, the lateral projection 12 and the hook 13 being substantially parallel with the rail. The key is lowered until its base 10 rests upon the flange 1 and the said lateral projection 12 comes just beneath the flange A. The key is then rotated so that the free end of the hook engages the top of the rail flange 8 preferably as soon as the key begins to turn. The end of the hook 13 will as it climbs up the inclined surface of the rail flange 8 bite progressively harder thereon and when the key is turned so as to bring the lateral projection 12 against the flange 3 the hook 123 will have its maximum locking action binding the anchor and the rail together. The portion 15 of the key 2 just above the base 10 is a cam which Works against the edge of the rail flange 8 and clamps the rail flange tightly between the hook 6 and the said key. The base 10 is extended laterally on the opposite side of the hook 13 as shown at 16 to form a brace to stiffen the key against the pressure of the hook 13.

Then a train traveling on the rail 8 from top downward on Fig. 1 is being stopped by brakes, the rail tends to creep in the direction of travel of the train. As the flange 3 is against the side oi a tie not shown) the tendency of the rail to creep will be resisted by the rail anchor, and the tendency of the rail to creep will tend to retain the bite or the hook 13 in the flange 8, and the lateral projection 12 of the key tends to hold the key from turning beyond a point where the bite of the hook will diminish.

In Fig. 7 I have shown the tongue 5 struck up out of the flange 1, leaving themetal entirely surrounding the same. The said tongue 5' is not bent back over the top flange but is driven upwardly and made parallel with the flange to form a seat for the edge of the rail flange.

I olaim-- 1. In a rail-anchor a member having a vertical flange for engagement with the side of a rail tie and lying beneath the rail and having at one end means engaging one. flange of a rail and at'the other end a slot adjacent to the edge of the other flange of the rail, in combination with a key having a member projecting down through the said slot and locking the key to the said member when the key is rotated and also having an 111"- wardly extending resilient hook engageable at its end only with the upper surface of the adj aeent rail-flange when the key is rotated.

2. In a rail-anchor, a member having a vertical flange for engagement with a side of a rail tie and lying beneath the rail and having at one end means engaging one flange of a rail and at the other end a slot adjacent to the edge of the other flange of the rail, in combination with a key having a mem'er projecting down through the said slot, a lateral extension on the projecting member arranged to pass through the slot and engage the lower face of the anchor, a cam on the key adapted to engage the edge of the adjacent rail-flzm 'e and an elastic hook on the key adapted to ride up on the upper surface of the said rail-flange when the key is rotated.

In testimony whereof, I hereunto aflix my signature this lei-th day of November, 1923.

CHARLES H. KNELL.
