To allan/loin#img/concern:

Be it known that we, WILLIAM A. Boon and RICHARD G. BooK, both citizens of the United States, and residents of Chicago, Cook county, State of illinois, have invented new and useful Improvements in -Rail- Anchors, of which the following is a specification, reference being had to the accompanying drawing, in ivhich- Figure 1 is an end elevation of our improved rail anchor showing the saine applied to a rail., the latter being illustrated in section. lFig. 2 is a top plan view of a portion of .a rail, a portion of a tie and our impi'oved rail anchor applied thereto. Fig. 3 is a top plan view of one member of our rail anchor, the full lines showing the operative position of said member. on the rail, the latter being indicated by dotted lines` and the dotted Vposition of said member indicating the position in which it is first applied to the rail. nd Fig. 4 is an end elevation of the rail anchor, showing the opposite end to that illustrated in Fig. l, the arm or extension of the' follower being illustrated in section. The position of the plate shown in elevation corresponds to the dotted position of the saine member illustrated in lig. 3.

The object of our invention is to provide a rail anchor of simple and cheap forni which may be made entirely by casting and wherein the parts automatically increase the grip on the rail as the latter tends to creep, the gripping being effected by a relative twisting of the rail anchor parts.

Referring to said drawing. A denotes a gripping plate; ll a follower or locking bar coperahle with said plate: C a section of a standard rail; and D a tie. l v

The gripping plate A. as shown. comprises a horizontal portion l() provided at each end thereof with upwardly extended inturned flanges l1 and 12 adapted to fit over and. firmly grip the edges of the rail base. The gripping flanges l1 and l2 extend diagonally to the axis of the rail when the plate A is arranged at right angles to the rail, as clearly indicated by dotted lines in Fig. 3 and said gripping flanges ll and 12 are so spaced that the plate A may be fitted over the rail base when at right angles to the rail. After the plate A has been applied to the rail base as above described. it is turned at an angle thereto as indicated by the full lines in Fig. 3, in which position it will he apparent that the flanges 11 and 12 overlap the edges of the rail base and firmly grip the latter. The plate A is also provided in the top face of the portion 10 thereof with a groove or channel 13 which eX- tends at an acute angle to the axis of the rail on which the flange l5 is seated than the other edge of the rail; and an extension or arin 1S of substantially rectangular cross section and adapted to slide within said groove or channel 13 of the gripping plate A. The ariu or extension 18 is inclined to the axis of the rail at an acute angle when the follower B is in position-` the angle corresponding to the angle of the channel or groove relatively tothe axis of the rail. The depending flange or abutment 17 may be suitably braced as by the rib 19.

ln applying the rail anchor to a rail, the follower B is put in position against the tie l); then the gripping plate A is applied to the rail as hereinbefore described and most Aclearly illustrated in Fig. 3, whereupon the member A is moved longitudinally of the rail toward the follower E. The arm 18 of the latter enters the groove 13 and as the gripping plate` ii is hammered home, it is apparent that the members B and A will loe relatively twisted` thus causing a pinching of the rail at three spaced points, two on one edge and one on the opposite edge. Any tendency of the rail to creep will naturally shift the plate Si toward the follower B and automatically increase the gripping action between the members. As is apparent from the precedingr description, no tapered or wedging surfaces are employed or necessary and the gripping action is entirely in-y dependent of such surfaces. Consequently, loosening of the parts resulting from alte`rnating expansion and contraction under the inuence of heat is overcome, one ofv the defects of prior types of rail anchors, which are dependent upon a Wedging' action to maintain the grip.

As will be apparent to those skilled in the art, various changes and modifications may be made in the details of construction and arrangement of parts without departing from the spirit of the invention Iand we contemplate all changes and modifications that come within the scope of the claims appended hereto.

We claim:

l. A rail anchor comprising, a gripping plate having portions thereof arranged to grip opposite edges of a rail base, and a locking bar arranged to. engagea tie, said bar having means to engage one rail base edge only and an extension coperable with said gripping plate, the extension being at an angle to ythe. axis of a rail and thereby et'- fecting a twisting action of the plate and bar upon relative approach thereof.

2. A rai-l anchor of the character described comprising, a gripping plate havingr flanged ends arranged to grip opposite edges of a rail base, said gripping plate extending at an angle to the axis of the rail when in operative position, and a follower having a tie engaging abutment, said follower being provided with means for gripping one edge of. a'rail base and having an arm extending at an angle to the axis of the rail, said arm passing; through and engaging' a channel in said plate.k

3. A rail anchor of' the character deiscribed, ceinprising, a follower member having means for engaginfg one edge of a rail and an abutment to engage a tie, said follower member beine provided with an arm extending at an acute angle tov the Iaxis of the rail when in position, and a gripping plate extending transversely to the axis oi' the rail, said plate havin;r a channel to receive said arm, the follower and plate being' twisted relatively to the rail base to ,grip the latter as the plate is forced toward the follower,

4. A. rail anchor of the character described, comprisine'. a follower having a flange at one side thereoic arranged to en- ,Qjage over and grip one edge of a rail base, said :fol-lover havingr a deiiendinn' flange'arranged to abut a tie, said `fdllower being provided also with an arm extending' at an acute angle to the axis of the rail when said fol/lower is in position, and a. gripping' plate extendingV normally at an angle to the axis or' the rail and having flanged ends arranged to engage and g'rip'the opposite edges of a rail base, said plate having' a channel to receive said arm, the channel being inclined to correspond with the angle of said arm relatively to the axis of the rail, wherebv. 'as the plate moves toward the follower, the

l operate, and a 'ing means on t .two members are relatively twisted and more firmly grip the rail base.

ra'il anchor of the character described comprising, a follower having an upwardly and inwardlyV turned flange at one side thereof arranged to grip one edge of a rail base, said follower having' a de pending abutment adapted to engage a tie and provided also with an integral arm extending at an angle td the axis otthe rail with which said follower is adapted to cogripping plate extending transversely of the rail and having integral opposed, upwardly and inwardly turned flanges arranged to engage and grip the opposite edgesl of the rail base, said plate having a recess on its upper face inclined to correspond with said arm and adapted to receive the latter, whereby. as theplate and follower move relatively toward each other,

the same are twisted and more firmly gripthe rail base.

6. A. rail anchor of the character described comprising, a gripping plate having flanged ends ar anged to grip opposite edges of a rail base, said ends being oil'set lengthh wise of the rail when said plate is in position, and a follower having a tie engaging` abutment, said follower being provided also with means for gripping an edge of a rail base and having an arm extending at an angie to the axis of the rail, said arm being seated in a correspondingly shaped channel provided in said plate.

7. A rail anchor of the character described comprising, a follower having a tic engaging abutment and'means for gril'iping one edge of a rail base, said follower being' provided with an arm extending away i'rom the tie engaging' abutment and in a direction away troni the side on which said means are located and a gripping' plate havhe opposite ends thereof adapted to engage and grip the opposite edges of a rail base, said means on said plate being oii'set lengthwise of the rail when said plate is in position, the means on said plate engaging' the saine edge oi the rail hase as the means on the follower heing farther away from the tie engaging' abutment than the lmeans on the opposite end of said plate, said plate having' a channel in its upper face within which is rcceived said arm, whereby, upon movement ot' said plate relatively toward the Jfollower, the plate and follower are relatively twisted tof/more firmly grip the rail base.
