BENJAMIN B. BETTS, OF ST. LOUIS, MISSOURI.
RAIL-ANCHOR.
Specification of Letters Patent.
Patented Aug. 25, 1914.
Application filed January 25, 1909. Serial No. 474,144.
To all whom it may concern:
Be it known that I, BENJAMIN B. Bn'r'rs,
a citizen of the United States, and a resident of the city of St. Louis, Missouri, have invented certain new and useful Improve ments in Rail-Anchors, of which the following is a full,'true, and exact description, such as will enable others skilled in the art to make and use the same.
My invention relates to means for preventing the longitudinal movement of creep ing of railroad rails and has particular reference to improvements in devices of the class known as rail anchors or anti-creepers.
The object of my invention is to provide an improved anchor or abutment between a rail and the tie which shall operate to prevent-movement of the rail across the tie.
Another object of my invention is to provide rail anchoring means of this class which may be readily applied tothe rail and adjusted to clamping position with a minimum amount of labor.
A further object; of the invention is to so improve rail anchoring devices that the same shall be automatically tightened and in effect permanently bound upon the rail by movement of the latter across the tie.
Still further objects of the invention are to provide improved rail anchoring means which shall be of minimum weight, of low cost and great strength.
y invention consists generally in a rail anchor or anchoring means comprising a bar or plate of somewhat greater length than the width of the rail base and adapted for application to the bottom thereof, in combination with means on the ends of the plate for engagement with opposite base flanges of the rail and suitable means for coaction with a cross tie to operatively set and maintain the rail engaging means or parts in action upon the rail.
My invention also consists in various special forms, construction and features and in combinations of parts, all embraced in the structural principle next above outlined and therewith, hereinafter more fully described and defined.
The invention will be more readily understood by reference to the accompanying drawings forming part of this specification and in which Figure 1 is a plan view of a rail anchor embo .ying my invention; Fig. 2 is an end View thereof; Fig. 3 illustrates my parallel motion rail anchor. Fig. 4 is a transverse elevation thereof.
In both forms of my device shown in these drawings it will be observed that the device comprises a plate or bar which reaches across the bottom of the rail, which is in some manner placed in abutment with or tied to the cross tie in such manner as to admit of movement of the ends of the plate or bar and which is provided, at its ends with parts which are adapted to clamp, bear or cramp upon or against the edge portions of the rail base.
Having thus generally defined my invention I will proceed to the specific descrip- Referring now to Figs. 1 and 2: In these figures and throughout the drawings A represents the rail and B the cross tie. For bridge structures where there is but little room between the ties as well as for other uses I form my device as shown in Figs. 1
and 2, the same comprising blocks 63, 63 which are oppositely disposed, to the end that they may act alternately during reversals of the tide of traflic on the bridge. The blocks are of identical form and each has an angularly arranged abutment arm or strut 64.- terminating in a plate 64 for engagement with the tie. The rail end of the part 63 comprises a large rotary wedging hook 65, the under jaw of which projects some distance beneath the rail. The two blocks are bound together by a cross bolt 66 and it is obvious that any force which tends to throw the bolt out of perpendicular with the rail axis will cause the distance between the jaws to diminish; hence both jaws will be the more forcibly jammed upon the rail flanges. The construction of the wedging lugs is such that their ends bite into the rail base and when thus engaged cannot be dislodged by vibration, removal of the bolt being the only means of loosening the anchor. When the rail moves in the direction of the arrow 0 the right hand abutment engages the tie toward which the rail moves and when the movement is reversed, as indicated by arrow at, the left hand abutment is brought into play. It should be understood that this exchange of abutments and in the working directions of the rail anchor takes place Without shifting the parts or changing the angularity of the bolts beneath the rail.
Comparison of Figs. 1 and 3 will make it clear that the advantages of the Fig. 1 device may be secured and accentuated by employing the principle oi parallel motion links. These links are, in Figs. 3 and 4t, the cross bolts 88, 88 having their ends secured in the blocks or jaws 89, 89, the latter being provided with wedge members 89 and the V grooves therein being smaller at the bottoms than the edges of the rail. The part 89" of each block bears directly against the rail edge and the blocks occupy reverse positions so that but one thereof engages the tie ltlovement oi the rail toward the tie blows the links or bolts 88 out of parallel with the tie and one end of each bolt being limited in movement by the direct abutment part 89, both bolts act to draw the respective wedge lugs or jaws more firmly upon the rail. This device, like that hereinbeiore described, is preferably reversible, to prevent excessive backward movement of the rail when the tide of traffic is changed.
fhough I have herein shown but two forms of my invention it is capable of still further modification and I do not confine or limit the invention to the precise constructions herein shown and described.
Having thus described my invention, I claim as new and desire to secure by Letters Patent:
1. A Z shaped rail anchor of the character described comprising two separate, substantially-similar oppositely disposed jaws, said jaws being formed to grip the upper and lower surfaces of the rail base, but not to contact with the edges thereof, a bolt passing through said jaws to draw the same together, and a tie engaging abutment projecting laterally from each of said jaws and extending beyond the other of said jaws to permit the movement of the latter jaw toward the tie and thereby effect the rotative wedging action of said jaws on the rail base, substantially as described.
2. A rail anchor comprising opposed jaws "for engaging the base flange of the rail, and parallel motion bolts connecting said jaws, substantially as described.
A. rail anchor comprising opposed jaws for engaging the opposite flanges of the rail base, and
tending laterally in opposite directions from the jaws at the opposite ends of said parallel motion bolts, substantially as described.
In testimony whereof, I have hereunto set my hand, this 30th day of October, 1908, in the presence of Copies of thispatent may be'obtained for five centseach, bfaddressing the Commissioneroffatents, Washington, D. 0.
