RAIL-ANCHOR TIE PLATE.

Application and March 9, i925. seriaino. 14,061.

To all whom it may concern:

Be it known that I, EMERY M. MOVICKER, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented a certain new and useful Improvement in Rail- Anchor Tie Plates, of whichthe following is a full, clear, concise, and exact descrip- .tion, reference being had to the accompanying drawings, formlng a part of this specification.

This invention relates to rail anchor tie plates. r

In some stretches of track 1t is a practical impossibility to permanently and absolutely fix the rails against vertical vibration resulting from the peculiar wavelike or weaving action induced therein by the intensive localized loads momentarily lmposed by the passing traffic. 7 Attempts to prevent this vertical vibration usually result in severe wear upon the rail securing means with ultimate failure of the parts affected.

One object of the present invention is the provision of a rail anchor tie plate which will permit limited vertical vibration of the rail and at the same time effectively secure the same against side thrust and longitudinal creeping.

Another object is the provision of an effective tie plate of simple form which may be manufactured at slight cost.

Other objects and advantages will appear from the following description of the embodiments of the present invention.

In the drawings:

Figure 1 is aiplan view of a tie plate constructed in accordance with the present invention and showing the same applied to a rail of standard form.

Figure 2 is a sectional view taken on the line 22 of Figure 1.

Figure 3 is a perspectlve view of a rail clamp employed.

Figure 4 isa plan view of a tie plate somewhat different 1n form embodying features of the present invention.

Figure 5 is a sectional view taken on the line 5-5 of Figure 4.

Figure 6 is a sectional view taken on the line 66 of Figure 4.

The tie plate shown in Figures 1 and 2 is formed from a substantially rectangular heavy steel plate 10, approximately one half inch thick, although the thickness may vary from about three eighths to three quarters of an inch, depending upon the service for WhlCh it is intended. Two integral hooks 11 are provided adjacent diagonal corners of the plate. Each hook is formed by strik- 1ng up a corner of the plate and shearing the same from the body of the plate, substantially along the line 12, so as to leave the struck up portion or tang, thus formed, integrally connected at one end to the plate. The struck up portions are then bent over on themselves to provide permanent hooks of appropriate form adapted to overhang the opposite sideflanges 13 of the base of the rail 14. Two slots14 are punched through the plate. Each slot 14 is positioned so as to extend beneath the rail substantially opposite one of the hooks 11. A substantially U-shaped rail clamp 15 is associated with each slot and adapted to embrace the edge of one-of the flanges 13. Each clamp comprises an upper jaw 16 overlying a rail flange and a lower jaw 17, seated in a slot 14., and underlying the flange. Each clamp is held in place by a spike 18 of usual form driven through the outer end of the slot 14 into the tie 19. Each clamp is securely bound to the rail flange by a wedge 20 driven into position between the jaw 16 and the upper face of the rail flange. The jaw 16 is preferably notched as at 21 or otherwise fashioned to provide an appropriate retaining seat for the wedge.

In applying the tie plate it is first turned I to overhang the rail flanges. The plate is] then adjusted along the'rail into the desired position on the tie. The clamps 15 are then inserted into the slots 14 with their lower jaws 17 underlying the rail flanges, and the spikes 18 driven into position behind the clamps. The spikes thus not only retain the clamps in rail embracing positlon, but also serve to secure the tie plate to the tie. The wedges 20 are then driven between the upper jaws 16 of the clamps and the top of the rail flanges so as to eifect a firm grip between the clamps and the ra l.

It will be noted from an inspectlon of Figure 2 that there is a slight clearance 22 between each hook 11 and the top of the associated rail flange. It will also be noted that although the clamps 15 are securely bound to the rail, there is nothing to prevent vertical movement between the clamps l5 and the tie late. A slight vertical play of the rail wit respect to the tie plate is thus permitted, the extent of this play being determined by the clearance 22 beneath the upper jaws of the hooks 11.

However, the rail is securely held against lateral play by the engagement of the flanges thereof against the bodies of the hooks 11, and longitudinal creeping is prevented by the engagement of the lowerjaws 17 of the clamps within the slots 14. Any tendency to creep causes the clamps to rock slightly so as to increase their grip upon the rail.

The wedges 20 are driven up from time to time to compensate for wear and are preferably retained in position by bending up the ends in the manner indicated.

Additional holes 23 are preferably provided through the tie plate to accommodate additional spikes when occasion arises.

The tie plate shown in Figures 4, 5 and 6 is similar in many respects to that described in my Patent No. 1,460,819, issued July 3, 1923. This tie plate is formed from a substantially rectangular heavy plate 10 of steel having portions 24 of its edges struck up to form thrust sustaining shoulders 25 adapt-ed to bear against the edges of the rail base and to firmly hold the rail against side play. The plate is punched to form openings, each having a narrow portion 26 extending beneath the rail and a wide portion 27. Portions 28 of the opposite edges of each opening are struck up out of the plate, to form additional thrust sustaining shoulders and also to provide retaining means for rail clamps 29. Each rail clamp comprises upper and lower jaws 30 and 31, for embracing an edge of the rail base, and a thickened base portion providing lateral lugs 32, adapted to engage beneath the struck up portions 28 of the tie plate. Each clamp is retained in position by means of a spike 33 driven into the opening 27 behind the clamp and into the tie. A wedge 34: driven into position between the upper jaw 30 of each clamp and the rail flange insures a firm grip between the clamp and rail. The upper 'aw 30 of each clamp is preferably grooved, as at 35, to provide an appropriate seat for the wedge, the wedge being retained in position by bending up the end thereof, as indicated.

It will be noted from Figure 5 that a slight clearance is provided at 36 between the lugs 32 of the clamp and the bent up portions 28. This clearance permits slight vertical vibration of the rail with respect to the tie plate and determines the extent of such vibration. The engagement of the lower jaw 31 of each clamp in the narrow opening 27 in the tie plate effectively prevents creeping of the rail.

Openings 37 punched through the tie plate permit the use of additional spikes when occasion arises to more firmely secure the tie plate to the tie.

Various changes may be made in either of the embodiments of the invention hereinabove described, without departing from or sacrificing any of the advantages of the invention as defined in the appended claims.
