TIE-PLATE RAIL ANCHOR.

Original No. 1,463,344, dated July 31, 1923, Serial .No'. 626,527, filed March 21, 1923. Application for reissue filed October 10, 1924. Serial No. 742,915.

To all whom it may concern:

Be it known that I, HENRY STEPHENS, a citizen of the United States, and a resident of Cleveland, county of Cuyahoga, and State of Ohio, have invented a new and useful Improvement in Tie-Plate Rail Anchors, of which the following is a speci fication, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

The subject of the present invention is a combined tie plate and rail anchor for railroad rails, and more particularly the invention relates to the particular form of the anchor member and the method of mounting the same on the tie plate so as to serve as an anchor in both directions. Provision is also made to overcome the normal wear between rail and tie plate so as to prevent the anchor from coming loose.

To the accomplishment of the foregoing and related ends, said invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims.

The accompanying drawing and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but one of various mechanical forms in which the principle of the invention may be used.

In said accompanying drawing Fig. 1 is a vertical sectional view through a tie plate and rail showing the anchor member in elevation; Fig. 2 is a plan view of a section of rail on the tie plate with the anchor member in place; Fig. 3 is a section on the line 33 of Fig. 2; Figs. 4 and 5 are views similar to Figs. 1 and 2 respectively but showing a modified form of anchor member and slot; Fig. 6 is a section on the line 6-6 of Fig. 5; and Fig. 7 is a fragmentary view showing the normal and engaging positions of the jaws of the anchor member.

As illustrated, there is shown the usual tie plate 1 having an abutment or shoulder 2, the rail resting on the plate with the outer edge 3 of the base flange 4 against the abutment. The tie plate is provided with the usual apertures 5 to receive the spikes used to hold the rail in place.

On the gage side of the rail, the tie plate is provided with an anchor member receiving slot 6 which is preferably the shape of a double trapezoid with the narrow parts connected forming a six sided slot, narrow at the center, which is substantially in line with the inner edge 7 of the base flange of the rail. The two outer sides 8 of the slot are cut at an angle so that the slot is wider at the top than at the bottom as is best shown in Fig. 3. An anchor member 10 is mounted in the slot,

the member being U-shaped with a slot.

therein to receive the rail base flange. The lower portion 11 of the member is of substantially the thickness of the tie plate and the member is wide enough to fit fairly snugly in the narrow portion of the slot. The upper portion 12 of the member has its lower or flange engaging surface 13 formed at an angle so as to engage with the sloping upper surface of the base flange of the. rail, but, as shown in Fig. 7, the angle between the two portions of the anchor member is less than the angle between the lower and upper surfaces of the base flange of the rail. The anchor member is formed of spring steel and may be driven on said base flange and the angle, as shown in Fig. 7, is the same for both forms of anchor members.

In the form shown in Fig. 2 the gage end of the slot is formed on acurve and with a radius less than the distance between the center line and the end of the slot so that as the member tends to pivot around about the center line it will be forced tighter onto the base flange. Furthermore, in any tipping action of the anchor member which may occur as shown in dotted lines in Fig. 3, the edges of the member tend to dig into or grip the base flange tighter.

The form shown in Figs. 4 to 6 is similar to that shown in Figs. 1 to 3 but here the anchor member 20 is more nearly V-shaped, the twolegs 21 being similar and having their end faces22 at right angles to the outer surfaces 23 of the legs so that either face 22 will contact with the ends 24 of the slot 25 which is formed like the slot 6 except for the outer end 24 which is parallel with the edge of the base flange of the rail. The end faces 22 are at an angle to the plane of the sides of the mem bar and the anchor member is normally placed at an acute angle to the line of the -base fla'ngeand towardthe, end of the rail and forceit tighter onto the flange.

member is slightly shorter than the slot.

It will be noted that the anchor member is free to move inwardly of the slot as: the In placing the'present device on a rail the tie 'plate is inserted'under the rail, with the anchor member in place'a nd the tie plate and inemberare driven into position from the the end of such memberwbemg adapted to "gage side of the rail until the base flange of the rail drops into position'b'ehind the abut ."ments 2. \Vith the type of slot and anchor "member'illustrated in Figs. 1 and 2 the base'fla'nge.

and 5,"the member is 'at an angle and it is t'merely'fnecessary' to reverse the member to member is'normally at'right angles to the In the 'form shown in Figs. 4

present the same to resist movement in the other direction.

In the presentdevice the anchor member is permitted'to have verticalmovement with .the trail independently of the tie plate, but

"movement. transversely of the rail is prevented as the anchor holds the rail tightly against'the tie plate shoulders or abutments.

Wear between the base flange and the. abutments is automatically compensated for by the spring action of the anchor itself and slight transverse movement of the tie plate due to loose spikes does not afiect the holding power of the anchor except as it might force the member tighter on the base "flange.

The present anchor is mounted on the gauge-side of the rail and this is an import ant feature as where similar types of anchor'members have been employed on the opposite side they quickly loosen and become ineffective if the tie plate moves outwardly and as the tendency is always to force the rail and tie plate outwardly, that is to Widen the gauge, an anchor member on the.

outside has been found unsatisfactory.

The present tie plate and anchor members are easy to manufacture and the slot in the tie plate is merely punched out when the spike apertures are formed while the anchor members are punched or cut out of spring steel stock.

Other modes of applying the principle of my invention may be employed instead of the one eXplained,-change being made as tion of a tie'plate having: anabutment on one "side and a slot on the gage side of the rail,

such slot being narrower at the center than at the ends, and an anchor member provided with base flange engaglng members mounted in such slot and adapted to pivot about the narrow center thereof.
