Application filed September 21, 1905. Serial No. 279,485.
. T aZl whom it may concern.-
Be it known that 1, JOHN L. DAHL, a citizen of the United States, residing at Weehawken, in the county of Hudson and State of New Jersey, have invented new and us :ful Improvements in Rail-Fastening Devices, of which the following is a specification.
This invention relates to devices for hold ing steel rails upon steel ties.
The objects of the invention are to improve and simplify the construction of such devices; furthermore, to increase their efficiency in operation and to decrease the expense attending their manufacture.
With the foregoing and other objects in View, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed as a practical embodiment thereof.
In the accompanying drawings, forming part of this specification, Figure 1 is a transverse section, partly in elevation, of a device constructed in accordance with the present invention. Fig. 2 is a plan View thereof. Fig. 3 is an under plan view thereof. Fig. 4 is a view similar to Fig. 1, showing the modified construction.
Like reference-nurnerals indicate corresponding parts in the different figures of the drawings.
The referencanumeral 1 indicates a rail-tie, which preferably, although not essentially, is constructed of steel and may be of any suitable form and construction. The rail-tie 1 is formed with perforations 2, which preferably are elongated in shape, although said perforations may be round, oblong, or otherwise shaped, if desired. Resting upon the rail-tie 1 is a steel rail 3, having a base portion formed with the usual oppositely-inclined upper surfaces 4 5.
Arranged transversely with respect to the rail 3 beneath the tie 1 is a bolt 6, having upweirdly-extending diverging threaded ends 7 and 7 The angle at which the ends 7 and 7 diverge with respect to each othenis such that the end 7 is disposed at a right angle with respect to the adjacent inclined surface 4 of the rail-base, and the end 7 is disposed at a right angle with respect to the adjacent inclined surface 5 of the rail-base.
Surrounding the threaded ends 7 and 7 of the bolt 6 are washers 8 and 9. As clearly shown in Fig.1, one side of the washer S rests upon the upper inclined surface 4 of the railbase and is parallel therewith, the opposite side of said washer contacting with the upper surface of the rail-tie 1. The washer 9 is similarly arranged with respect to the upper inclined surface 5 of the rail-base. Each of the washers 8 and 9 is formed with one flattened side 10, which is adapted to be arranged adjacent to the upper surface of the rail-tie 1. Furthermore, each of the washers 8 and 9 is beveled inward from the flat side thereof, as indicated at 11 in Fig. 1, so that each of the washers has a comparatively large surface in contact with the rail-tie 1. Each of the ends 7 and 7 of the bolt 6 is provided with a nut 12, which serves to hold the adjacent washer firmly in position.
It will be observed from the drawings that the nuts 12 are sufficiently large to overlap the sides of the rail-base, so as to aid the washers in holding the rail in position and cause the pressure of the nuts to be exerted directly on the rail.
By forming the bolt 6 with diverging up wardly-extending ends as distinguished from upwardly-extending parallel ends a double purchase is exerted upon the base of the rail 3-that is to say, the washers 8 and 9 are not only forced downward against the rail-base and the rail-tie, but said washers are also drawn toward each other, so that liability of the ends 7 and 7 spreading and permitting the washers to slip off the rail-base is avoided. By forming the washers 8 and 9 with flattened sides and beveled lower ends said washers have a larger surface contact with the rail-tie l and are thus not only prevented from cutting into the rail-tie, but are also strengthened or rendered more rigid, so as to prevent the ends 7 and 7 of the bolt 6 from spreading when the nuts 12 are tightened.
The construction illustrated in Fig. 4 is ex- .actly the same as that illustrated in Figs. 1,
2, and 3, except that the washers 8 and 9 are not formed with flattened and beveled portions, for which reason when the nuts 12 are tightened the washers are caused to bend or flex slightly, as shown, and thus act in a measure as a nut-lock to prevent accidental loosening of the nuts 12.
If desired, the washers 8 and 9 (shown in Fig. 4) may be formed with flattened sides 10, as indicated in Fig. 2, eliminating bevel 11. (Indicated in Fig. 1.)
Having thus described the invention,what is claimed as new is l. The combination with a railway-tie having perforations, and a rail resting upon said tie and having a base portion formed with oppositely-inclined upper surfaces, of a bolt arranged transversely to the rail beneath the tie and having upwardly-extending diverging threaded ends, each of said ends being disposed at a right angle with respect to the adjacent inclined portion of the rail-base, and a nut upon each of the threaded ends of the bolt, each of the nuts being sufficiently large to overlap the adjacent inclined portion of the rail-base.
2. The combination with a metallic railway-tie having elongated perforations therein and a rail resting upon said tie, and having a base portion formed with oppositely-inclined upper surfaces, of a bolt arranged transversely to the rail beneath the tie and having upwardly-extending diverging threaded ends, each of said ends being disposed at a right angle with respect to the adjacent inclined portion of the rail-base, a washer surrounding each of the threaded ends, one side of each washer resting upon the adjacent inclined portion of the railbase and being parallel therewith, and the opposite side of each washer contacting with the rail-tie and a nut upon each of the threaded ends for holding the washer in place, each of the nuts being sufliciently large to overlap the adjacent inclined portion of the rail-base.
3. The combination with a metallic railway-tie having a perforation and a rail resting upon said tie and having a base portion formed with an inclined upper surface of a bolt extending through the perforation of the rail-tie and having a threaded end disposed at a right angle with respect to the inclined surface, and a nut on the threaded end overlapping the inclined surface.
4. In a railway-tie fastening consisting of a U-shaped bolt having its ends extended through the tie and serving to clamp a rail to the tie, a deflected end to the bolt provided with a nut overlapping and bearing down upon the top of the rail-base and inclined to have an extended bearing on the rail-base, substantially as described.
In testimony whereof I have affixed my signature in presence of two witnesses.
