Specification of Letters Patent.

Patented Aug. 1, '1%11.

Application filed Getooer 17, 1910. `Serial No. 587,484.

T o all whom it may concern.'

Be it known that l, CHARLES F. CLAW- soN, a citizen of the United States, residing at Mount Pleasant, in the county of Henry and State. gf Iowa, have invented certain new and useful lmprovements in Rail- Anchors; and I do declare the following to be a full7 clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. A

vThis invention relates to improvements in anchors for railway rails.

One object of the invention is to provide a railway anchor having an improved means whereby the same is secured in rigid engagement with a rail and the latter thereby positively held against creeping.

Another object is to provide a rail anchor which will be extremely simple and exceptionally strong in construction and which may be quickly and easily ,applied to a rail.

lV ith the foregoing and other objects in view, the invention consists of certain novel featuresl of construction, combination and arrangement of parts as will be more fully described and particularly pointed out in th Y appended claim.

In the accompanying drawings: Figure 1 is a vertical cross sectional View through my improved anchor showing the same applied to a rail; Fig. 2 is a topplan view of a portion of a rail and tie showing the application of the anchor thereto; Fig. 3

is a vertical sectional view through ithc anchor looking toward one side thereof;.

lt ig. i is a similar view looking toward the opposite side; Fig. 5 is a perspective view of the wedge or gripping member looking toward the. outer side thereof; and,y Fig, (j

bottoni plan View of the Wedge. ltig.

7 is a vertical cross sectional view ou the line 7-7 of Fig. 3.

Referring more particularly to the draw- 4Tings, 1 denotes the body portion of my im- .proved anchor, said body portion comprising a base plate 2 which is preferably of greater width at one side than the other and which is provided with a flat upper 'surface adapted to engage the base of the rail as shown. Gir the under side of .the plate Q adjacent to Vits front and feat' are l'mfnml reinforcing; lianges 3 and on he front edge of the plate 2 adjacent to one curved stop lug 4 which is adapted to engage the side of the tie when the anchor is arranged in position on the rail.

On one end of the plate 2 is formed. an upwardly projecting rail engaging flange 5 having on its upper edge an overhanging lip G. rlfhe flange 5 and lip (i are adapted to be engaged with one edge or base or liange of the rail. rllhe tia'nge 5 and lip (3 are braced at the front and rear ends thereof by a continuation of the reinforcing ribs C3 on the front. and rear edges of the plate 2. @n the opposite end of the plate 2 is formed an upwardly projecting wedge receiving flange 7 having on its upper edge an overhanging lip 8. The front and rear ends of the tiange 7 and lip 8 are reinforced by a continuation of the opposite ends of the ribs 3. The flange 7 is formed at a slight angle with respect to the flange 5 and on the inner surface of the flange 7 is formed a series of teeth 9 while on the inner .side of the lip 8 is formed a series of teeth 1t). On the upper side of the -platc 2 adjacent to the flange 7 is formed a row or series of teeth 11.

The plate 2 is of somewhat greater length than the width of the base or flange` of the rail and when the plate is engaged with the rail one edge of the base tits into and eugages the flange 5 and lip t3 at one end of thc anchor, whilel between the opposite edge of the base of the rail and the z yigular or obliquely disposed flange 7 at the other end of the plate is formed a tapered space with which is adapted to be engaged a gripping member or wedge 12 which comprises a tapered bar 13 having on the inner edge of its upper side an upwardly and laterally projecting flange 14 the outer surface or edge of which above the upper side of thc bar 13 has formed thereon a series of teeth 15 which are adapted to engage the teeth 10 on the adjacent edge of the lip 8 when the wedge is engaged 'with the space between the flange 7 and the adjacent edge of the base of the rail. lNhcn the wedge 12 is thus engaged with this space the laterally projecting portion of the flange 14 will tit over and engage the adjacent edge of the base of the rail as shown. The rail engaging surface. of the lange is preferably provided with a serien o' teeth 1h. ln order to provide a tight engagement between the adjoining edges or lower side of the bar and the adjacent upper side oit the plate 2, I provide said adjoining or adjacent edge of the bar with series of teeth 1T which engage the teeth on the adjacent surfaces of the flange, rib and plate and thereby hold the wedge or gripping member I2 in operative engagement with the rail whereby any creeping movement of the latter' is positively prevented.

In applying the device the body portion l is slipped over the base flanges of a rail as shown in Figs. l and 2, and the wedge member or bar 123 is then driven into position as shown. The enlarged teeth or serrations on the opposing bearing -faces of the wedge member and the adjacent parts of the body member, are, of course, sufficiently small to permit the wedge member to be driven into ver irm frictional engagement with the" 'flange 7 and the adjacent base flange of the track rail and such teeth or serrations ,will etfectually prevent the parts from Working loose,

By referring more particularly to Fig. 'l of the drawings, it will be noted that the wedge' or tapered locking bar has its upper outer corner cut away so that the bar may tit under and against the overhanging lip on the adjacent liange oi the base plate and that the said tapered locking bar or wedge is provided on its opposite side with an overhanging lip which engages over the base or [lange of the rail. The wedge or locking bar is thus` prevented from twisting relative to the rail or the base plate and obtains an eX- tended bearing both against the rail and the base plate. The accidental dislodgment of the tapered bar will be prevented and it cannot work' loose under the jarring oit' passing trains inasmuch as the only movement it can have will be longitudinally and the releasing movcuient of the bar alor g its length will be prevented by the engagement of the several teeth shown and described. These teeth, furthermore, pei-mit the wedge to be adjusted approximately to its final locking position while the device is being placed in posi tion so that it will not slip out ot place while the parts are being assembled and. after the base plate and the wedge have been'brought into proper relation to the rail, a few light taps from a hammer or other tool will drive the wedge home so as f having a depending tie engaging lug on one side at one end and provided at its opposite ends with upstandmg tlanges and overhang ing lips at the upper edges ot said flanges,

Aone of said flanges being adapted t-o engage a rail base and the other of said tlanges being provided with teeth on its side and on the inner edge and under side of its over-- hanging lip, and a wedge adapted to lit between the rail base and the toothed tlange and lip of the base plate, said web having one longitudinal .corner cut away wherebyit may lit under and against the lip and provided on its opposite side with an overhanging lip adapted to lit over the rail base, the wedge being j )rovided with teeth on the under side of said lip to engage the rail basel and on its several outer 'faces to engage the teeth of' the base plate.

In testimony whereof I have hereunto set my hand iin presence oi two subscrilfling witnesses.
