To all Vwhom it nmfy'conccrn:

Be it known that l, JoiiN M. SCOTT, a citi' in the county of Racine and State of Wisconsin, have invent-cd certain new and useful following is a specification, reference being had to the accompanying drawings, forming :i part thereof.

The main objects of this invention are to ing lengthwise upon the ties on which they are laid,to securely hold the anchors on the rails, and prevent the rails from slipping therein, to reduce the weight, and generally simplify and improve the construction and` l t consists in certain novel features of construction aiid in the peculiar arran ement and combinations 'of parts, as hereinater described, and defined in the claims.

In the accompanying drawings like characiers designa-te the same parts ir. the several figures.

vFigure 1 is a vertical cross-section on the line `1 1, Fig. 3, of a rail-anchor embodying the present iuvention'as applied to a railway rail and tie. Fig. 2 is a side elevation of the anchor andof the rail to which it is applied as viewed from the ri Vlit with 'reference to Fig. 1, the tie being s town in cross-section on the line 2 2, Fig. 1. Fig. 3 is a lan view rail being shownvin horizontal section on the line 3 3, Fig. l. Fig. 4 is an elevation of the anchor as viewed from the left with reference to Fig. 2, the rail to which it is applied being shown in cross-section on the line 4 4, Fig. Fi". 5 is an inverted plan View of the anchor andz of the rail-base to which it is attached. Figs. 6, 7, and 8 are detail views showing sections on the lines 6 6, 7 7, and 8 8, respectively, Fig. 3. Fig. 9 is a perspective '10 is a cross-section of the wedge about mide anchor comprises two jaws a and b, which are grooved or recessed to fit over the c and a bolt d for adjustably connecting'said jaws and clamping them upon the rail-base. One jaw, r1, may be `forged or made integral withtlu-boltd in the form of a hook, or it-may i be made, as shown, separate from the bolt.

The other jaw b is formed with a transverse cylindrical openng cutting fec groove or rei cess for the rail-base lange 'parallel with and adjacent to the bolt-hole, which lies just below said groove or recess. In this openinga wedge e, of semicylindrical form, isiitted and adapted to turn on its upper side, the under side of the wedge being formed with. oid' or mori` longitudinal teethf, which are ade ted to bite into or to be embedded in the t oper side of the rail-base fiange held in the jaw b'. The outer and larger endv of the `wedge is formed, as shown in Figs. 2, 6, and 9, with a notch or angular recess g, with which a corner of the nut h on the adjacent end of the bolt d is turned into engagement and by which the wedge is held in place in -iiejaw and the nut is prevented from turning back and working loose upon the bolt. jaws-as, for example, .the jaw b-is formed with a transverse vertical bearing i, which is ada ted to abut against one side of a tie j, as s iown in Figs. 1, 2, and 3, and thus revent longitudinal movement of the rai towhich the anchor is attached without carry'- ing the tie with it. The wedge e and the opening in which itis fitted in the jaw b are so formed that end thrust on the railin the direction indicated. by the arrow on Fig. 2 tends to turn the wedge in the jaw and to in.- crease its bite and tighten the gri ofthe jaw on the base-fiangeof the rail. lnder ordinary circumstances this alone will serve to revent the rail from slipping in the anchor; )ut as a further safeguard the jaw `b is provided, as shown in Figs. 3 and 7, with an en guiar key 7c, which is inseted in a vertical socket of corresponding shape cutting the groove or recess for the rail-base flange, a sharp angle or corner of the key being .presented townrd and adapted to vbite into or to be embedded in the edge of the rail-base flan e held in said iaw. This, key may be mana of quadrangular shape, asshown, or of any other form in cross-section'which will present a shiirppangle or corner to the edge of the rail-base.

While both jaws of the 'anchor may be made tocori'espond with thc jaw l, onel right and the other left, to fit upon opposite edges or flanges of the rail-base, :in elim-tivi nnchor is made hv connecting u jaw, such as a. of simpler and lighter construct ion wil h n si n Vgle `aw b, thereby materially reducing the tota weight and cost of the anchor without correspondingly reducing its strength and efficiency.

One ofthe lloo lnapplying the anchor to n. rail the jaws a and l) are laced on o posite edges or flanges of the rai -baseY an drawn together and lclamped thereon b the bolt d, the nut after it has been screwe tightly against the outer face of the jaw b being turned in advance sufficiently to clear the opening for the wedve e, which is then inserted and driven into ace therein. The nut is then turned back slightly, so as to carry one corner thereof into the notch or angular recess g in the outer protruding end of the wedge, which. is thereby locked and held in place in the jaw', while the nut itself isheld against turning farther backward and working loose on the bolt. Before the nut is iinally tightened the key r may be embedded in the edge of the rail base or ilange by striking the outer face of the jaw a blow or two with a hammer.

The anchor may be as readily removed from a rail as it is applied thereto by turning the nut 7iy up orforward suiiiciently to clear the wedge and then rying the wedge out of the jaw b by placing t inner smaller end of the wedge and forcing the upper art of the bar against the railhead, whic serves as a fulcruin, After the wedge e has turned backward with a wrench and removed from the bolt, thereby releasing the jaws.

Various changes in the details of construction and iii the arrangement of parts may be made without affecting the principle and op'- eration of the anchor and without departing from lthe intended scope of the invention.

1. A rail-anchor comprising a recessed jaw adapted to be clamped Y having a' transverse opening cutting the recess i'or the rail-iiange, and a wedge fitting said opening and having one or more longitudinal teeth adapted to bite into the rail-flange, substantially as described.

"2. A rail-anchor com )rising a recessed jaw adapted to be clamped on a rail-iiange and having a transverse cylindrical opening cutting the recess for the rail-flange, and a semicylindrical wedge iitted and adapted to turn in said opening and formed on one side with a tooth which is adapted to bite into the rail flange, end thrust on the rail tending to turn said wedge and to increase its bite on the raillange, substantially as described.

BfA rail-anchor com rising a pair ot aws and a connecting-bolt or clamping them on a rail-base, one of said jaws having a recess e end of a bar-against the been removed the nut 71. can be A on a rail-iiange andk .to receive and fit for the rail-base, a transverse bolt-hole below said recess, and a transverse cylindrical opening cutting said recess adjacent to the bolt-hole7 and a semicylindrical wedge fitted and adapted'to turn in said opening and having a notch in its lar er end arranged to eno t and a longitudinal tooth on one side ada ted to bite into tial y as described.

4. A rail-anchor com adapted to be clampe and having cutting said recess, and a semicylindiical wedge fitted and adapted to turn in said openin teth which are adapted to bite into the railbase iiange, substantially as described.

5. In a rail-anchor the combination of a pair of recessed jaws, a bolt connecting said jaws and adapted to clamp them upon the base-flanges of a rail, one of the jaws having the rail-base, substanon a rail-base -flange age with a nut on t e adjacent end of the a transverse cylindrical openingy and formed on one side with longitudinal rising a recessed jaw atransverse bolt-hole, and a transverse cy- Y lindrical opening cutting the recess` for the rail-base'ilange adjacent to the bolt-hole, 'and asemicylindrical wedge fitted to turn ,in'said opening and having longitudinal teeth on one side to bite into said flange ajid a notch j or recess in the larger end arranged to engage with a nut on the adjacent end oi' the bolt, to

hold the wedge in place and prevent the nut i as described. 6. A rail-anchor comprisingav a jaw recessed to receive and lit over from' turning, substantiallya rail-base flange and having a vertical socket intersecting therecess for said flange and an angular. key inserted in said socket and adapted to bite into the edge of the rail-ange, described.

7. A rail-anchor comprising a jaw recessed over arail-base iiange and having a vertical socket and a transverse opening each cutting the recess for said baseilange, an angular key fitted in said socket' and adapted to bite into the edge of the railflange, and a toothed wedge fitted in said substantially as IOO opening and adapted to bite into'the top oi' the base-iiaiige, substantially as described.
