RAIL FASTENING.

Specification of Letters Patent.

Patented July 4, 1922.

Application filed October 20, 1921. Serial No; 509,039.

T 0 all whom it may 007106771.

Be it known that I, LOUIS D. Grimes, a citizen of the United States, residing at Hackensack, county of Bergen, State; ofv

New Jersey, have invented new and useful Improvements in Rail F astenings, of which the following is a specification.

This invention is an improvement upon the structure set forth by the GreggP-atent No. 638,922. The object of the present invention is to produce a rail-fastening which isapplicable at will for securing rails whose flanges are of varying vertical dimensions or'height-s to cross-ties of varying configurations.

Among the features constituting the in vention are: The longitudinal groove in the cross-ties is of rounded or arcuate cross-section, instead of straight-lined; the cross-tie has two holes for the two clips of each fastener, instead of having only one hole and loeating the outer clip at the very end of the cross-tie; the clip-members are of malleable material, such as machine-forged steel, instead of being castings as heretofore; the upper surface of the lower jaw of the clip is concaved and rounded, instead of being flat; the upper jaw of the clip extends sub-.

stantially-horizontally from the vertical portion thereof at substantially a right angle or less, instead of sloping upwardly; and the inside-clearance of the vertical portion of the clip is increased to exceed the vertical distance between the lowerbearing-surface of the tie and the outer upper edge of the rail-flange. The invention likewise comprises the various combinations of the above-mentioned features; and the other features hereinafter set forth and claimed.

The broad invention will be best understood by reference to apreferred concrete embodiment of all the various features, thereof illustrated in the accompanying,

Fig. 5 is a vertical section, similar to Fig. 2, but showing the end of a modified form of rail; and

Fig; 6 is a vertical section similar to Fig. 3, but showing a different form of cross-tie and a rail like that of Fig. 5.

Referring first to Figs. 1-4, 10 represents a cross-tie whose central longitudinal portion is depressed in curved or arcuate form, as at 12, to produce on its upper surface a longitudinal groove. 13 is a hole through said grooved portion for receiving one of the two fastening-clips; 14 is a larger opening nearer the end of the tie, for receiving the complementary clip and for manipulat ing the nut of a bolt; and 15 is the intermediate depressed portion of the tie. 16 is a rail, resting in position on the tie and lying above said depressed portion 15, between said hole and opening, and having the usual'base-flanges 1717 with inclined upper surfaces. 18 and 18 are a pair of identical but oppositely-disposed clip-members, each having a central bolt-h0le. Preferably, the height of the inner face 19 of the vertical portion of each clip, its vertical inner-clearance, exceeds the vertical distance between the bottom bearing-surface of the tie-depression 15 and the upper and outer edge 20 of said flanges. Each clip has. .a' substantially-horizontal upper jaw 21, which extends from said vertical face 19 at approximately a right angle or preferably even less. .Said vertical face 19 and the bottom face of said jaw 21 may be substantially-plane surfaces; but each clip haslikewise a. lower jaw'22, which is arcuate (when viewed in a direction transverse to the rail, as in Fig. 3) to present a concaved upper surface.

- l/Vhen a-"rail as 16 is laidin place above tie-portion 15,.intermediate hole 13 and opening 14, the pair of clips, 18 and 18, is applied to the rail-flanges and a bolt 23 inserted first through inner clip 18 and then through outer clip 18, and if desired the head of the bolt may be turned to engage the wall of the groove to prevent rotation; and then a nut 24 is screwed home upon said bolt to draw said clips towards one another and clamp them upon the railflanges and tie-depression.

As stated, preferably the vertical extent of said; inner face 19, the vertical inside clearance of the clip, slightly exceeds the vertical distance between the engaged surface of the tie-depression 15 and the upper outer edge of the superposed railflanges; so that, when the clips and their bolt have been located in position and the nut screwed home on its bolt, the outer edge of each upper j aw will pass over said upper outer edge'ofthe adjacentrail-flange, and will engage the inclined flange-surface along a line about midway of the flange. With a relatively thick flange, as 17 in Fig. 5,said engagement will be nearer the outer edge. And with a relatively-thin flange, the engagement will be nearer the rail; and, if necessary or desired, the upper clip-jaws canbe forced downward, as by hammering, either before or after assembling, to insure proper engagement. In either event, the tightening-up of the nut, with or without the hammering, will produce a wedging and clamping action to maintain anfirm engagement of the flanges and secure the rail in place; The fact that the'clipsare malleable is therefore of great advantage, in enabling the new fastener to be applied to rails of the different types.

1.111 Fig. 5 is indicated a'rail 16 having relatively-thicker flanges 17 with the usual inclined upper surfaces. With such rails, the upper jaws 21 need notbe hammered down, but will engage said inclined surfaces nearer the outer edges thanwith the thinner rail-flanges shown in Fig. 2; v

In Fig. 6 the central tie-depression 15, which constitutes the longitudinal groove, is rounded upon a radius subtantially shorter than that of depression 15 in Fig. 3; so that the lower clip-jaws 22 engage along the central portionof the under surface of said shorter-radius depression, as clearly indicated in Fig. 6; whereas a longer-radius depression is engaged along two separate lines or regions nearer the outer edges of the jaw, as indicated in Fig. 3.

The invention has thus been described with considerable detail, but only for the sake of clearness; since it is to be understood that the invention is not limited to the precise construction and arrangement set forth, but may be embodied in various forms, and parts of the invention may be omitted, with out departing from the spirit of the broad invention. 1 i

The invention having thus been described, what is claimed is: A
