Fig. 3 of the drawings. This yoke is preferably In practicing my invention I provide a yoke of made of relatively thick high grade iron or steel substantially channel shape in lateral section and includes a web portion H as well as two sub- 20 having upper rail-base-embracing portions and stantially vertically-extending side walls 19 and locate within said yoke a key member of wedge 2|.

The end 25 gaging the bottom surface of the rail base and the portions of the side walls 19 and 2| at the left upper surface of the web portion of the yoke to hand side of rail I3 are designated by numeral thereby hold the anchor structure firmly in its 24 in Fig. 1 of the drawings, and by numeral 25 proper operative position on the rail. Integral at the'right hand side of Fig. 1. These over- 80 portions of the key at its narrower end are hanging jaws or portions are separated from the adapted to be bent around the adjacent end of intermediate parts of the sides by recesses 21 and the yoke, to hold the key in its adjusted and 29, the recess 21 differing slightly in shape from driven position in the yoke. recess 29, also in a manner well known in the art,

In the drawings, to permit of easily and quickly mounting the Figure 1 is a view, in side elevation, of a rail unitary rail anchor assembly on the base 23 of 35 anchor embodying my invention and shown in the rail. This is accomplished by moving the its proper operative position on a rail, yoke toward the right of the rail, as seen in Fig. 1 Fig. 2 is a top plan view of the rail anchor of the drawings, until it occupies the position assembly shown in Fig. l of the drawings, shown by the broken lines 3|, when it will be 40 Fig. 3 is a view, in vertical section therethrough, possible for the jaws 25 at the right hand side to 40 taken on the line IIIIII of Fig. 1, be moved upwardly and slightly above the sloping Fig. 4 is a view, in vertical section similar to upper surface of the base 23, after which the that of Fig, 3 but showing a slightly modified yoke can be moved to the left into the position form of rail anchor, shown by the full lines in Fig. l of the drawings.

Fig. 5 is a view, in vertical longitudinal section, I wish to point out particularly that the upper 45 of a still further modification of device embodysurface of the web portion I! of the yoke does not ing my invention, extend parallel to the bottom surface of the rail Fig. 6 is aview, in vertical lateral section therebase, but extends at a slight angle relatively through, taken on the line VI-VI of Fig. 5, thereto for a purpose to be hereinafter set forth Fig. 7 is a top plan view of the rail anchor in detail. The web portion I1 is provided with 50 shown in Figs. 5 and 6, two longitudinally-extending recesses 35 whose Fig. 8 is a view, in vertical lateral section of purpose will be hereinafter set forth. These rea modified form of the structure shown in Figs. cesses are located in the web closely adjacent to 5, 6 and. 7, and inside of the side portions I9 and 2|. Fig. 9 is a view, in vertical longitudinal section A key member 31, which is here shown as of channel-shape in lateral section is located within the hereinbefore described yoke member l5, and

is also made of wedge-shape longitudinally thereof, the slope or change in its vertical height being substantially the same as that of the web I! relatively to the bottom surface of the rail base 23.

lhe key 31 is provided with two downwardly extending integral lugs 39, for which see particularly Fig. 3 of the drawings. These lugs are punched out of the web portion 4| of the key 31 thereby leaving an opening 43 in the web, as will be seen by reference to Fig, 20f the drawings. The lugs 39 extend downwardly through the elongated longitudinally-extending recesses 35 in the web l'i' of the yoke and, as shown in Fig. 3 of the drawings, the bottom ends thereof are bent outwardly over the bottom surface of the side walls of the yoke immediately adjacent to the recesses 35. I wish to point out that I do not rely upon frictional engagement between the outside surfaces of the side walls of thekey and the inside surfaces of the side walls I9 and 2| of the yoke, but that there is a small clearance therebetween so that the key will slide freely in the yoke when the anchor is not mounted in its proper operative position on the base of a rail. In other words, I rely entirely upon friction between the lower surface of the web of the key and the upper surface of the web of the yoke, and between the upper edges of the side walls of the key and the bottom surface of the base of the rail, to hold the anchor in its proper operative position thereon.

I have shown a pair of laterally projecting lugs 45 integral with the yoke I5 which are adapted to engage a metal tie plate 41 on a wooden tie 49, but these are not an essential part of my invention and may be omitted. I The smaller or shallower end of key 31 is provided with a plurality of longitudinally-extending saw cuts 5|, as shown in Fig. 2 of the drawings. After the unitary rail anchor assembly has been located in its proper operative position on the base of the rail, as hereinbefore described, the key 31, which was held in its furthermost right hand position, is then driven to the left, as seen in Fig.

of the drawings, until it is tightly wedged between the base of the rail and the web of the yoke. The design and construction are such that a part of the key will project beyond on the left hand end of the yoke 15. The projecting portions 53 of the side walis and the projecting portion 55 of the web may then be bent outwardly and downwardly respectively, as shown in Figs. 1 and 2 of the drawings to securely lock the key in the position into which it was driven, as by repeated blows of a hammer.

Referring now to Fig. 4 of the drawings, I have there illustrated a slightly modified form of key 51 which may be utilized with the yoke l5 hereinefore described. The key 51 has its intermediate or web portion 59 engaging the lower surface of base 23, while the lower surface of the side por tions 6i of the key frictionally engage the upper surface of the web 53 of the yoke 65. The yoke 55 is in general identical with the yoke i5 as was hereinbefore described. The side portions 5| of the key are provided'with short depending integral lugs 61 which extend downwardly through longitudinally extending recesses 69 in the web 53, the recesses 59 being the counterpart of the recesses 35 shown in Fig. 2 of the drawings. In all other respects the assembly of the key 51 in the yoke 65 is the same as for the parts shown in Figs. 1, 2, and 3. I have shown one side wall of the yoke 65 as located adjacent to one side of a tie 49, a tie plate 41 being located on the top of tie 49 to directly support the rail I 3.

Referring now to Figs. 5, 6 and '7, I have there shown a modified form of rail anchor comprising a yokemember H which is in general the counterpart of yoke l5 illustrated in Figs. 1, 2, and 3 of the drawings. The web 13 extends an gularly relatively to the base of the rail as was hereinbefore set forth for yoke l5.

A key member '55 is here shown as being of substantially box-shape in lateral section and is of greater vertical dimension at one end thereof than at the other end thereof. The lower web of key 75 provided with an opening 11 therein extending longitudinally thereof. The web portion '53 of the yoke has an upwardly extending lug 79 formed therefrom as by punching it out from the web, this lug being relatively short, fitting into the opening I? and being bent around the inner surface, substantially as shown in Fig.

6 of the drawings. This ensures that the key will be movably held in the yoke so that there is no danger of the two parts becoming disengaged during the time that they are handled after assembly and before they are located in proper operative position on a rail.

Here again I desire to point out that I do not rely upon friction between the vertically extending walls of the yoke and of the key, but utilize only the friction between substantially horizontally-extending surfaces. The narrower end of the key is provided with a plurality of saw cuts 8 I, shown more particularly in Fig. 7 of the drawings to provide a plurality of tongue portions 82 which may be bent outwardly and downwardly to lock the key in its proper operative position on the base of a rail.

I have shown a somewhat different form of key, in Fig. 8 or" the drawings, which may be used With a yoke The key 85 is of box shape lateral section and has a small integral portion 8'! bent downwardly through a longitudinal slot 89 in the web 9i of the yoke and around on side wall thereof, substantially as shown in the drawings.

I may point out here that the keys [5 and 85 are provided with a single locking lug only and that I may use a single depending

lug

39 or 61 instead of a pair of such lugs as shown in Figs. 3 v

drawings, I have there illustrated a still further 1 modification of a rail anchor embodying my invention. A yoke 93 of substantially channelshape in lateral section has a plurality of upper overhanging

jaw portions

95 and 91, which are similar in shape and use to the

portions

23 and 25 of yoke E5. The Web portion 99 of yoke 93 is provided with a longitudinal slot illl therein. A key I93 is of substantially bar shape, has a greater vertical dimension at one end thereof than at the other end, and is further provided with an integral depending lug I05 which extends through the recess or slot HH and is bent laterally around the bottom surface of the web 99, in a manner shown particularly in Fig. 10 of the drawings.

he side portions of yoke 93 may be provided with integral lateral extensions it]? which are the counterpart of the lateral lugs 45 of Figs. 1, 2 and 3. It may be here pointed out that the Web of yoke member 93 extends at a small angle relatively to the bottom of the rail base 23 and further that the key IE3 is of wedge shape, as will appear more particularly by reference to Fig. 9 of the drawings.

Preparatory to mounting the anchor on the rail the key I03 is moved as far to the right, as seen in Fig; 9 of the drawings, as the interfitting lug I05 and slot ml will permit. After the yoke has been properly located on the rail base, substantially as shown in Fig. 9 of the drawings, the key I03 is driven as far as may be possible into the yoke, so that its upper surface will frictionally engage the bottom surface of rail base 23 while its bottom surface will engage the upper surface of the web 93 of the yoke 93. The design and construction of the key is such that an end portion thereof, at its shallower end, will project beyond the yoke and this over-hanging portion Hi9 may be bent over against a side wall of the yoke 93 in order to hold the key in tightfitting engagement in the yoke and to prevent its becoming loose in operation and use of the track.

Referring to Fig. 12 of the drawings, the anchor assembly there shown comprises a yoke l I I, which is substantially the same as yoke 93 except that it is not provided with the lateral portions I01 and is therefore adapted to be located against a vertical surface of a tie 49. The key I03 may be used in this assembly, the interlock between the two members being provided by a depending lug H05 extending through a slot l! in the web 99 of the yoke.

I have shown the two side walls H3 and H in the positions they are to occupy when finished and ready for use. The two side walls are bent toward each other to substantially the positions shown in the drawings which is done with the key I03 in its initial position, that is where it is far to the right as possible, as seen in Fig. 9 of the drawings. When the assembly has been placed on the rail base and the key has been driven in, it will be held in its desired locking position not only by the frictional engagement with the bottom of the rail base and the top surface of the webof the yoke, but also by the inner surfaces of the side walls of the yoke. This provides an additional frictional holding means for the key.

The main characteristics of all of the modifications hereinbefore described may be briefly summed up as follows: the yoke member is so designed and constructed as to have a web portion which extends non-parallel with the base of the rail, and the key member operatively associated with the yoke is of wedge shape in vertical longitudinal section. The yoke and key have interfitting tongue and slot portions, the tongue portion extending through and beyond the slot and being bent laterally thereof in such manner that the two interfitting members cannot be disassembled by ordinary handling thereof, such as they may experience while being shipped or while being carried to the place where they are to be used. The rail anchor embodying my invention thus provides a unitary plural-section device which is simple, easily constructed as by punching operations, is easily assembled and which will remain in assembled position during ordinary handling thereof.

It is obvious that the slot in yoke need not be located in the web but could be located in a side wall of the yoke.

The device embodying my invention relies entirely upon friction between adjacent members located in horizontal planes and once the key member has been hammered into tight engagement between the web of the yoke and the bottom of the base of the rail it is held in such tightfitting position by having one or more integral end portions thereof bent out of their original plane and over against adjacent portions of the yoke.

It is obvious that further modifications can be made in the device embodying my invention without departing from the spirit and scope thereof, and I desire therefore that only such limitations shall be placed thereon as are imposed by the prior art or are set forth in the appended claims.
