MORGAN EDWARD REES, OF MORRISTON, NEAR SVTANSEA, WALES.

MEANS FOR SECURING RAILWAY-RAILS 'IO SLEEPERS.

T 0 all whom it may concern Be it known that I, MORGAN EDWARD Rims, a subject of the King of Great Britaln,

residing at Morriston, near Swansea, Gla-- sleeper and the ends of which pass through slots in the sleeper, these ends being suitably shaped, or provided with suitable meansto clamp the rail to the sleeper. The

part of the bolt which extends beneath the sleeper is bent or bowed so as to provide an upwardly directed elbow or crest which, when the nut at one end of the bolt is tightened, is drawn up against the underside of the sleeper which forms a fulcrum on which the bolt can rock, so that by tightening the nut at one end, the'rail clamping means at the other end of the bolt is simultaneously caused to clamp the rail more firmly against the sleeper. By reason of the bolt being free to rock about this elbow or crest, when the nut at one end is tightened, both ends of the bolt act as springs to take up any slight slackening or yielding of the parts which may occur in use.

In combination with this improved bolt, I provide a clip or doghaving a lug extending downwardly from the edge which rests upon the sleeper so that it'can enter the slot in the sleeper'through which the bolt pro jects. The length of the slots is such that the end walls thereof act as abutments for such lugs, or for the outer surface of the hooked end of the bolt, whereby the rail is positively held against lateral displacement in either direction.

In the accompanying drawings Figure 1 shows a rail in transverse section and a side View of a bolt and clip comprised in the improved means for securing railwa rails to sleepers.

ig. 2 is a plan view of the same.

Fig. 3 is a view similar to Fig. 1 illustrating a modified form of the bolt and clip.

Specification of Letters Patent. Patented llay 10, 1921, Application filed December 1," 1920. Serial No. 427,555.

Figs. 4 and 5 are views similar to Figs. land 2 illustrating a further modification of the bolt, hereinafter described.

.As shown in Figs. 1 and 2, the rail a is secured to asleeper b by a bolt 0 one end of which is hook shaped so that when this end has been introduced through a slot d in the sleeper, the lip e of the hook rests on the upper surface of the rail flange while the outside of the bend of the hook abuts against the outer end wall f of the slot (Zn When the hooked end of the bolt is in this position the shank of the bolt 0 extends underneath the sleeper to the opposite side of the rail where it is bent at an angle so that it extends above the sleeper through a slot 9 therein and through a hole in a clip or dog h. At this end the bolt is screw-threaded and provided with a nut 71.

One edge of this clip or dog rests upon the sleeper while the opposite end is recessed or forked so as to provide two surfaces is, one of which rests on the upper surface of the rail flange and the other presses, laterally againstthe edge of this flange. At a central or intermediate part of that edge of the is provided which extends downwardly into the slot 9 and bears against the outer wall m of this slot.

The part of the bolt 0 which extends beneath the sleeper is bent or bowed and arranged so that when the nut z is tightened the elbow or crest n of the bend or bow bears against the underside of the-sleeper.

' With this arrangement, when one edge of the clip h is resting on the sleeper and the surface j at the opposite end is resting on the rail flange and the intermediate part of the clip around the bolt is unsupported, if the nut i is tightened the clip is caused to clamp the flange on one side of the rail firmly to the sleeper. At the same time, owing to the bent 'or bowed shape of the bolt, the shank of the bolt acts like a lever whereby the hook shaped end of the bolt is caused to also clamp the flange on the opposite side of the rail firmly to the sleeper. The surface 7: on the clip bears against the edge of the flange of the rail and the lug Z bears against the end wall of the slot 9 and together act as a wedge to press the rail against the inside of the hook on the opposite side of the rail which bears against the end wall of the slot (2, so that the rail is thus held against displacement laterally on the sleeper. 'Moreover the bent or bowed shank, in addition to acting like a lever, acts as" a spring to keep the rail clamped to the sleeper even if the nut runs back a little owing to jarring or other causes.

' The screw-threaded end of the bolt may be arranged to extend upwardly substan: tially parallel to the web of the rail as shown in Fig. '1 or it may be inclined with reference to the said web as shown in Fig. 8 in which case the clip or dog is formed with'a suitably inclined upper surface 0 for the nut 11 to bear against. The edge of the clip or dogwhich rests on the sleeper may have a bead p formed thereonas shown in Figs. 1 and 3.

In the modified arrangement shown in Figs. 4 and 5 both ends of the bolt 0 are screw threaded and clips or dogs 72, as above described are provided at both ends of the bolt to clamp the flanges to the sleeper at 7 points on opposite sides of the rail.

With this improved means for securing railway rails to sleepers the necessity of forming embossed or stamped up parts such as are usually provided insheet metal sleepers to keep the rails properly spaced apart, is avoided, itbeing. onlynecessary to form slots in the sleeper through which the bolts project, the dogs then acting to determine the position in which the rails are held.

What I claim is:

1 A bolt for securing railway rails to,

sleepers, comprising a shank adapted to be arranged beneath the sleeper transversely to the ra l and bent so as to provide an upwvardly directed elbow to bear against the underside of the-sleeper, and having end portions adapted to project through the sleeper on opposite sides of the rail and provided with means for clamping the ra l flange to the sleeper.

3. Means for securing railway rails to sleepers, comprising a bolt' having a bent shank providing an upwardly extending elbow arranged beneath the sleeper, and having its ends adapted to project through the sleeper, one end of the bolt being screw threaded to receive a nut, and a clip which can be clamped on the rail flange by the said nut.

4. Means for securing railway rails to sleepers, comprising a bolt having a bent shank providing an upwardly extending elbow arranged beneath the sleeper and having its ends adapted to project through the sleeper, having one of its ends screw threaded to receive a nut,and a clip having the upper andlateral surfaces of the rail flange. V

6. Meansfor securing railway rails to sleepers, comprising a bolt havinga bent shank providing an upwardly eiztending elbow arranged beneath the sleeper and having its ends adapted to project upwardly through slots in the sleeper and to abut againstthe ends of the said slots one end of said bolt being screw threaded. to receive a clip and a nut on said screw threaded end forclamping the clip against the rail'flange.

7. Means for securing railway rails to sleepers comprising a bolt having a bent shank providing an upwardly extending elbow arranged beneath the sleeper and having its ends adapted to project upwardly through slots in the sleeper, one end of the bolt being screw threaded to receive a nut.

a clip mounted on said screw threaded end and having a lug adapted to extend down wardly from said clip into the slot in the sleeper through which this end of the bolt passes.
