ANTICEEEPING DEVICE FOR RAILWAY-RAILS.

Specification of Letters Patent.

Patented Jan. 28, 1919.

Application filed October 12, 1917. Serial No. 196,319.

To all whom it may concern:

Be it known that I, WILLIAM M. MITCH- ELL, a citizen of the United tSates and a resident of Louisville, county of Jefferson, and State of Kentucky, have invented certain new and useful Improvements in Anticreeping Devices for Railway-Rails, of which the following is a specification.

The improvement relates to anchors for preventing the longitudinal creeping of railway rails and seeks to provide a simple, effective means connected with the angled spliced bars or the like to prevent creeping. Heretofore, as an aid in preventing creeping of the rails and some times as a sole means used for this purpose, it has been customary to cut slots in the lower flanges of joint splice bars and other angle bars bolted to the rail and drive track spikes through these slots into the ties. But this cutting or notching of the flanges of splice bars necessarily weakens the rail joints and the pressure on the spikes tends to Weaken and destroy the ties particularly if the latter are chemicallytreated, soft wood ties such as are now largely used.

In accordance With the present invention, an anchor is fused or welded at its upper portion to 2. splice or like bar bolted to the rail and is provided with a depending abutment which engages the side face of one of the cross ties. Such a construction is cheap and eflicient, can be readily applied to splice bars and angle bars now in position on the track and will eflectively prevent the creeping of the rails or aid in so doing without injury to the tie. Preferred forms of the present invention are hereinafter fully set forth in the accompanying drawings and the essential features of the invention are pointed out in the claims.

In the drawings, Figure 1 is a plan view of a rail joint equipped with the present invention. Fig. 2 is a cross section on the line indicated in Fig. 1. Fig. 3 is a view ofa blank for making the form of anchor shown in Figs. 1 and 2. Fig. 4 is a cross section illustrating another form of the invention.

The rails 10 are carried on the supporting cross ties 11 and the adjacent ends of the rails are connected by splicing angle bars 12 connected thereto by track bolts 13 and having base flanges 14 which fit upon the flanges of the rail base and project outwardly beyond the edges thereof. Track spikes 15 are driven into the ties and engage the flanges 14 of the angle bars to hold the rails against lateral movement. In accordance with the present invention anchors are fused or welded to the angle bars and preferably to the outer portions of the lower flanges thereof and are provided with broad depending portions which abut against the side face of the ties and resist the creeping of the rails without injury to the ties. IVhile the projecting edges of the'lower flanges 14 of the angle bars may be slotted to receive the track spikes, such slots are preferably omitted to avoid weakening the angle bars and to prevent the tendency of the rail to creep longitudinally from exerting pressure on the spikes and thus injuring the ties.

The form of anchor shown in Figs. 1 and 2 comprises an abutment 16 arranged to engage the side face of the tie, an integral brace portion or member 17 which extends rearwardly from the inner edge of the abutment 16 and a transverse flange or member 18 which extends real-wardly from the upper end of the abutment and is inclined upwardly and inwardly therefrom. Such an anchor can be readily and inexpensively formed from sheet iron or steel or from a short section of a flat, forged iron or steel bar by notching the side edge thereof, as indicated in Fig. 3, bending the portion below the notch upon the vertical line a to form the brace member 17 that extends rearwardly from the inner edge of the abutment 16, and bending the portion above the notch upon the transverse inclined line b to form the upwardly and inwardly inclined flange 18.

The anchor is placed in position with the abutment 16 engaging the side face of the tie, the brace member 17 beneath and in engagement with the outer projecting edge of the flange 14 of the angle bar and with the flange 18 engaging the upper face thereof. The anchor-can be then readily welded in position preferably by fusing together adjacent portions of the anchor flange 18 and angle bar flange 14 by means of a portable oxy-acetylene torch or the like. To avoid in any way weakening the metal of the bars, the adjacent portions of the flanges 14 and 18 are heated nearly to the fusion point and a fillet fused from a steel rod is run about the edges of the portion of the flange 18 in contact with the flange 14 as indicated at 0. Such a fillet or fillets is thus united or incorporated with the metal of the anchor and of the angle bar to permanently unite these parts.

It should be noted that the parts 17 and 18 form jaw members which embrace the edge portion of the flange 1 k and aid in resisting the pressure on the welded joint. As shown in Fig. 1, anchors may be applied to resist creeping in opposite directions if desired.

The anchor shown in Fig. 4 comprises a tie-engaging abutment 19 having a rearwardly extending flange or bracing portion 20 at its outer edge. The latter has an extension 21 at its upper edge which overlaps and is fused or welded to the edge of the angle bar flange 14 and is preferably offset as shown, to form a shoulder 22 that extends beneath the edge of the flange 14. Preferably, the anchor is united to the angle bar fiangeby an added metal fillet fused to the upwardly projecting extension 21 and to the edge of the angle bar flange, as indicated at d. This form of anchor can be readily made of a short section of angle bar or from a piece of forged sheet iron or steel.

It is obvious that changes may be made in the details set forth without departure from the essentials of the invention, as defined in the claims.

I claim as my invention:

1. The combination with railway rails, supporting cross-ties and splice bars connecting said rails, of an anchor fused or welded to one of said splice bars andvhalving a depending portion abutting against the side of one of said ties.

2. The combination with a railway rail and a supporting cross-tie, of a bar connected to the rail and having a flange projecting outwardly over the rail base, and an anchor comprising a part fusedor welded to the flange of said bar and a depending abutment engaging the side of said tie.

3. The combination with a railway rail and a supporting cross-tie, of a splice bar connected to said rail having a flange proj eating outwardly beyond the edge of the rail base, and an anchor comprising a tie engaging abutment, a bracing member and a part engaging and fused or welded to the outer portion of said flange.

4. The combination with a railway rail and a supporting cross-tie, of a splice bar connected to said rail having a flange projecting outwardly beyond the edge of the rail base, and an anchor comprising a 'tie engaging abutment and jaw menibers e ngaging the outer portionof said flange, said anchor being fused or welded to said flange.

5. The combination with a. railway rail and a supporting cross tie, of asplice bar connected to said rail having a flange projecting outwardly beyond the edge of the rail base, and an anchor comprising'atie engaging abut1nent, a bracing member extending rearw ardly from said abutment and arranged beneath the projecting edge 'of said splice-bar flange, and a flange member at the upper end of said abutment engaging and fused or welded to said angle-bar flange.

6. The combination with a railway rail. and a supportingcross tie, of a splice bar connected to said rail and having an outwardly projecting flange, and an anchor having a member overlapping and fusedfor welded to the upper face of said flange, said anchor being adapted tocooperate with said cross tie to hold the rail against creep-ing.v

7. The combination with a railway Irail and a supporting cross tie, of a splicing bar connected to the rail and having an outwardly projecting flange, and an anchor comprising a tie engaging abutment and upper and lower jaw members embracing said flange, said upper jaw member being fused or welded to said flange.
