RAIL ANCHOR.

Application filed November 24, 1924, Serial No. 751,837. Renewed June 1, 1926.

Rail anchors as usually heretofore constructed grip the rail and abut against the tie so that the longitudinal movement of the rail in one direction is transmitted to the tie, which resists the same as it is embedded in the ballast. But'such devices act only in one direction, and do not hold the rail against movement in the reverse direction caused by reversal or trafiic or by the expansion and contraction of the rail or by its reaction from the wave movement of one-way trafic.

The object of the present invention is to provide a two-way rail anchor by which the tie resists all movements of the rail in both directions of its length.

In the accompanying drawings Fig. 1 is a top plan View of a device embodying my invention in place on a rail and tie, and

Fig. 2 is a view in transverse cross-section on the line 22 in'Fig. 1, the tie bein omitted for convenience of illustration, an

3 is a sectional view on the line 3-3 in the drawings the reference letter A designates the head of a rail, 13 its base and C its web, and D a tie. A rectangular tie-plate E is fiormed of sufiicient size to have one side extend beyond the side of the tie when the plate is spiked thereto in track as shown in Fig. 1, and the extended or orerhanging portion of the plate is provided with a transverse slot 6 which is longer than the width of the rail-base B and is large enough to admit a rail-gri F which exten 5 across the base of the rail' and grips both flanges of its base. In the form shown the slot in the tie-plate is at a right-angle to the length of the rail, and the stay is in the form of a bar consisting'of a yoke f and upwardly and inwardly curved jaws or hooks f. The stay is made of metal and is so shaped and proportioned that when its yoke f is placed beneath the rail in the slot of an associated plate its jaws 7" will project up through the slot and grip the flanges of the rail-base. In the embodiment shown the stay is applied to the rail either by slipping it onto the rail-base at either end thereof or by hooking one of its jaws onto one flange of the rail base with the yoke extending more or less in the line of the rail and then swinging the stay on its hooked end as a pivot into position across the rail to engage the other jaw with the opposite flange of the rail-base, there being in either case a slight distortion of the stay to develop a spring grip on the rail. The stays are applied to the rail at such points along its length that when the rail is seated on its tie-plates the stays will register with and lie in the slots in the plate, which latter are spiked to the ties. In practice I ma employ any suitable form of stay or rai gripping member whose body when in the slot of its associated plate extends across the rail-base and has opposite rail-engaging devices near its ends which extend up through the slot in position to engage the flanges of the base to resist the creeping of the rail. The rail-engaging devices take a firmigrip on the rail so that the stay by bearing against the sides of the slot will transmit all longitudinal movements which the rail ma have in either direction to the plate, an as the plate is spiked to the tie as at G the latter resists the longitudinal movement of the rail in both directions. Also, as the slot e is in the line of the side of the tie and the stay projects below the plate it abuts against the tie to take the strain oil the spikes G in the ease of trafiic in the same directiomas the arrows on the line 2-2 in Fig, 1. By this construction a rail-anchor age is provided which resists rail creeping in both directions, and which is simple in construction, readily assembled with the rail and tie, and eificient in action to interlock the rail and tie to hold the rail against longitudinal movement, and as the stay and 'its slot are preferably proportioned so that the end of the stay bear against the closed ends of the slot' the device at the same time interlocks the rail and plate so that the latterlalso resists all the lateral thrust of the rai I claim:

1. YA rail-anchor consisting of a tie-plate constructed with an extension projecting beyond one side of the associated tie and having a slot transverse to the length of a rail-base and longer than the width of said base, and a rail-stay consisting of a bar extending across the underside of the railbase and having jaws extending upward throu h said slot and gripping said base.

2. rail-anchor consisting of a tie-plate constructed with an extension projecting beyond one side of the associated tie and having a slot at a right-angle to the length of a rail-base and longer than the width of said base, and a rail-stay consisting of a bar extendin across the underside of the railhase an having jaws extending upward through the ends of said slot and gripping said base.

3. A rail-anchor eonsistin of a tie-plate constructed with an extension project-in beyond one side of the associated tie an having a slot transverse to the length of a rail-base and longer than the width of said base, and a rail-stay having a bed constructed to enter and bear against bot sides of the slot and extend across the underside of the rail-base and rail-engaging devices near its ends extending upward throughthe slot to engage the flanges of the base.

In testimony whereof I hereto affix my signature.
