RAIL ANCHOR.

Application filed l'annary This invention relates to rail anchoring devices, adapted to prevent the creep of the rail, when in service, in either one or both directions.

On railroad tracks where the traHic in general moves always in one direction, substantially all of the tendency to cree will be in this one direction and so-calle oneway rail anchors are used adapted to transmit this thrust to the ties and roadbed. In some trackways, due to the passage of trains in both directions, or other causes', the track tends to creep alternately, first in one direction and then in the other, and so-called two-way rail anchors must be used. Such anchors usually take the form of some means permanently secured or bolted to both the rail and one or more of the ties. Such anchors are difficult to apply and tend to weaken the rail at the point of application. Since such an anchor must share the up and Adown motion of the rail, this action tends to pull or Work loose the spikes with whichv the anchor is secured to the tie. When the rails of a stretch of railway track are to be removed or replaced, the entire anchor must also be removed, and since these anchors are usually placed on the rail opposite a joint in the other rail, and the joints will be at new ositions after the rails have been relaid, it is often necessary to re-position the ties and provide new rail openings for bolting the anchors in place.

The general object of the present invention is to provide an improved anchor, of simple and economical construction, capable of use either as a one-way or two-way anchor.

Another object is to provide a simple sprin anchor member capable of being quick y and easilyV applied to the rail base, and gripping the rail with a constant spring pressure.

' Another object is to provide a. simple onepiece rail gripping memberl adapted to interchangeably form part of either a onewa or a two-way rail anchor.

nother object is to provide an improved applying tool or hook for positioning the rail-gripping member on the rail.

Another object is to provide an anchor comprising two members, one of which grips the rail, and the other being permanently secured to a tie, the two membersjengaging one another to prevent relative horizontion shown in Fig. 1.

tal movement, but each being capable of vertical movement independently of the other.

Another object is to provide a two-way anchor, secured partly to the ties and partly to the rail, whereby horizontal lengthwise movement of the rail in either direction is resisted, but free vertical movement of the rail is permitted without putting stress on the tie engaging portions of the anchor.

Another object is to rovide a rail anchor member adapted to istribute the thrust from the rail gripping member to a tie and tie-plate, without permitting the rail gripping member to come in actual engagement w1th the tie.

Another object is to provide a rail anchor comprislng two cooperating members secured to the tie and rall, respectively, whereby the rail and rail ipping member may be removed without disturbing the tieengaging member. Another object is to provide a rail anchor mcludmg a portion which is anchored to adjacent ties with an extension member or members for distributing thetlirust among additional ties.

Other objects and advantages of this in- -vention will be apparent from the following detailed description of certain approved forms ofthe devices.

The rail 1 is supported by its base 2 upon the tie plates 3 carried by the ties 4, the base 2 being held down against the tie plates and ties b the spikes 5 in the usual manner.

Re erring rst to Figs. -3 and 4, the railgripping portion of the rail anchor is formed of a single piece metallic bar 6, preferably of substantially square cross-section. The bar 6 has an intermediate downwardly bowed portion 7 terminating at either end in substantially horizontal portions having surfaces 8 and 9 adapted to bear against the under surface or bottom of the rail base 2 adjacent either` edge thereof. One end of the bar is curved upwardly and inwardly, as

'at 10, to form a hooked end enclosing .a

notch 11 adapted to fit about one edge of the rail base 2 and bear thereagainst. There is a small angular clearance at 11 between the upper side of notch 11 and the upper surface of the rail base flange to permit a limited vertical swinging movement of the gripping Inember about this edge of the rail base when the gripping member is being applied. The other end of bar 6 is turned upwardly, as at 12, and then outwardly, as at 13, to form a lug which is engaged by the applying tool 14 when the member is being positioned on the rail base. In the inner face of the upwardly extending portion 12 is formed a notch 15, oppositely disposed to notch 11, the two

notches

11 and 15 being spaced apart a distance vsubstantially equal to, or slightly less than, the width of the rail base, so that when the member 6 is applied to the rail, the rail base will be snugly gripped between the two upturned ends of this bar 6. The downwardly bowed portion 7 is sufficiently elastic to form a powerful spring which may be flexed sufliciently to permit the application of the member to the rail base, and will subsequently hold the notched ends of the bar firmly in engagement with the opposite rail base flanges. A cam-surface 16 is formed on the inner face of the upturned end portion 12, extending from the upper edge of notch 15 to the upper surface of lug 13.

)When the member `6 is to be applied to the rail, the end 10 is first hooked from beneath onto one edge of the rail base, so that the notch 11 is engaged with this edge of the rail base flange. This position of the member is indicated in dotted lines in Fig. 3. The lower eye or looped end 17 of the tool 14 is now hooked over the lug 13, and the tool 14 is of such length that the enlarged head 18 will extend approximately level with the upper surface of the rail 1. An ordinary claw-bar 19, such as is used -for removing spikes, is now engaged with the head 18 of the tool 14, and by fulcruming the bar'19 upon the rail 1, the bar 6 may be drawn up into engagement with the rail base. The spring 7 will flex and permit cam surface 16 to guide the edge of the rail base into cngagement with the notch 15. The tool 14 may be conveniently formed by welding the eye 17 onto the end of an ordinary track spike.

A simplified form of rail-gripping nicmber, and applying tool therefor, are shown in Figs. 5 and 6. The bar 6 is provided with the same bowed spring portion 7 and hooked end 10 as in the form first described. However, the lug 13 is omitted, and this end 20 of the bar is inturned, similarly to the end 10, to enclose the notch 15. The cam surface 16 is formed on this end of the anchor as in the first described modification. In lieu of the lug 13, the under surface of the hooked end 20 is provided with a depression or socket 21, into which is adapted to be engaged the upturned end of the hook 22 on the applying tool, which forms an integral extension of the lower end of the spike 14 and replaces the loop 17 previously described. Obviously, the applying operation is the same as with the forms of gripping member and applying tool first described. This latter form of gripping member is simpler and easier to manufacture and eliminates the lug 13 which is a useless projection after the anchor is once applied. The lug 13 gives a longer leverage to the applying tool, but on the other hand the upward pull on lug 13 is directly opposed to the outward spring of the member caused by the engagement of cam 16 with the rail base edge. This latter objection is avoided by applying the upward pull in socket 21 by means of hook 22.

In the form of two-way anchor shown in Figs. 1, 2 and 3, a suitable length of angle bar 22 is bent intermediatelv at 23 to form an elbow which will project adjacent one edge of the rail base 2, while the ends 24 and 25 rest upon a pair of adjacent ties 4 beyond the ends of the tie plates 3. The ends 24 and 25 may be secured to the ties in any suitable manner, as by means of the ordinary spikes 26. The angled face of the elbow 23 is cut away or notched, as at 27, to engage about the hooked end 10 of the rail gripping member 6. The notch 27 fits fairly closely against the sides of hooked end 10, but is of Sufficient height to permit free ver ist tical movement of the rail 1 and gripping member 6 without necessitating any corresponding movement of the anchoring plate 22. j

After the member 6 is applied to the rail base 2, it grips the'oppo'site edges of this rail base bythe spring pressure furnished by the downwardly bowed portion 7 with sucient pressure to resist movement of the member longitudinally of the rail, and prevent any material canting' of the member in the plane of the rail base.` However, if a pressure is applied lengthwise of the rail to one end of the bar 6, for example, the hooked end 10, there will be a tendency to cant, or a very slight canting of the member, in a horizontal plane, which will cause the gripping member to engage the rail base even more firmly and securely lock the gripping member to the rail. This j canting movement is so slight that the member will be locked by a force exerted in either direction lengthwise of the rail without causing any material movement of the gripping member along the rail base. Vith the parts in position, as shown in Figs. 1, 2 and 3, any creeping of rail 1 in either direction will brin the hooked end 10 of the gripping memgber 6 into engagement with one side or the other of notch 27 in the anchoring plate 22, and any further thrust of the rail will lock the gripping member 6 firmly in position on the rail and transmit the thrust through the plate 22 to the ties 4. At `the same time the up and down, or wave motion of rail 1, as the trains -pass thereover, will be permitted, without causing any'corresponding movement of the anchoring late 22, since the gripping member 6 is permitted free vertical movement in the slot or notch 27 in the plate 22. rlhe rail 1, or the gripping mem er 6, or both of them, may be removed and replaced without necessitating any disturbance of the anchoring plate 22.

Thus there are no vertical thrusts tending' to loosen the spikes 26, and since the ends 24 and 25 of the plate 22 are secured directly to the ties 4, beyond the ends of the tie plates 3, this anchorage is enduring, regardless of the shifting movements of the rail either vertically or horizontally. When the rail 1 is relaid, or a new rail is positioned on the ties, a. member 6 can be applied to the rail base directly in line with the notched portion 27 of the anchorage plate 22 without requiring any movement or readjustment of this plate. his is possible since the application of the gripping member 6 is performed entirely in a vertical plane without requiring any lateral shifting whatever of the gripping member.

In Fig. 7 is shown a slightly modified form of the anchorage plate. The -plate 28 here shown is substantially the same as the plate 22 previouslyl described, but is reversely bent to form a straight `central portion 29 adjacent the edge of the rail base, and parallel lstraight'.

end portions

30 and 31 which rest on the ties 4, directly beyond the ends of the tie plates 3. This plate is a little more diilicult to form, but has the advantages of not being weakened by being bent at the notch, and also is positioned more compactly against the sides of the rail, particularly at its ends and 31, so as to avoid objectionable projections along the sides of the track.

`The simple form of anchorage member 32 shown in Fig. 8 is a single flat plate centrally notched at 27 to engage the gripping member 6, and cut away at its ends, at 33 and 34,.to avoid the tie plates 3. The anchors shown in Figs. 7 and 8 operate in every Way substantially the same as theone described more in detail hereinabove and shown in Figs. 1, 2 and 3.

Another form of anchoring member is shown in Figs. 9 and 10. A lat metal strip 35, similar to the plate 32 in Fig. 8, has an intermediate forked projection 36enclosing the notch 37 for engaging the end of the rail-gripping member. One prong 38 of the `fork is deflected upwardly and adapted to extend over the adjacent flange of the rail base 2, and the other prong 39 of the fork is deflected downwardly beneath the rail base. The vertical spacing of these fork ends which overlap the rail base is suiicient to permit a limited amount of vertical movement of the rail and gripping member 6 independent of the late or anchoring meinber 35, but the en of the gripping member will never be permitted to move vertically completely out of the notch 37. The ends of bar or late l are anchored to the ties 4 at 40 in t e usual manner.

The last described form of anchoring member can b'e made, as shown in Figs. 11 and 12, of a strai ht bar or strip 41, and a casting 42 rivete or otherwise' secured to an intermediate portion of the bar 41, as at 43. The castin or forging 42 is formed with forked en s` 44 and 45, enclosing the notch 46 for accommodatin the rail gripping member-6, each

forke end

44 and 45 being notched or forked as at 47 to loosely engage the adjacent rail base edge and prevent excessive vertical movement of theV rail i independently of the anchoring plate.'

The anchoring member 48 shown in Figs.

13 and 14 is much the sameas the one shown gripping action on the Vrail and it is sometimes desirable to distribute the thrust from las7 this gripping member between more than two of the ties. For this purpose an extension bar 51. is provided, having a tongue 52 at one end adapted to intertit with and be secured to one end of the main bar 48, for example, by securing the same spike 53 through both bars. The other end of the extension bar 51 is secured to another tie as at 54. second extension bar could be added to the lirstone, or such a bar could also be used .at the other end of the main bar 48. Obviously, similar extension bars could be adapted for any of the other forms of anchoring bars heretofore described.

In Figs. 15 and 16 is illustrated a form of one-way anchor. The tie engaging member is an angular metallic bar having a horizontal portion 55 adapted to overlie the top of the tie plate 3, and a vertical portion 56 adapted to bear against one side of the tie 4. Horizontal portion 55 terminates in a downwardly extending spiked end 57 adapted to extend through one of the spike holes in the tie plate into the tie, and the vertical leg 56 terminates in a horizontal spike 58 adapted to be engaged into the side face of the tie. Interniediately, adjacent the upper corner of the tie 4, the anchoring'member is bent outwardly to form a lug 59 against which bears the hooked end 10 of the rail gripping bar 6. The operation of this form of anchor is substantially the same as that of the twoway anchor previously described, except that the one-way anchor is only effective against thrusts in one direction, that is, toward'the tie 4 to which the anchoring member 59 is applied.

It Awill be noted that the rail gripping member 6 is equally effective, either as a part of a one-way anchor or a two-way anchor. 1f both forms of anchors are to be used, only one form of rail gripping member need be supplied, and these maybe applied to, and will operate with, either Vthe two-way anchoring plates 22 or the one-Way anchoring members 59. The rail gripping members 6 are applied in the same manner, if either the one-way or two-way forms of anchor are to be used, it only being necessary that the member 6 be applied to the rail base so that the hooked end 10 will lie in proximity tothe portion of the

plates

22 or 59 with which it is to cooperate.

The gripping member 6 will be effective as a rail anchor provided any anchoring surface is present against which one end of the member may abut (in either direction) so as to obtain the slight canting tendency in a horizontal plane by which the member 6 is Securely locked to the rail base. It will `further be noted that in all of the forms of rail anchors here shown, although two parts are 'used, these parts merely abut against one another and there is vno necessity for properly mating or fitting these parts, so

Leone-r4 that no selection is required and either part may be replaced without altering the eciency of the anchor.

The rail gripping member 6 (either the form shown in Fig. 3 or the Jform shown in Fig. 5) might be applied to the rail by any upward pressure, for example, by fuleruming a crow bar on a tie or the roadbed and lifting up on the under surface of member 6 until the notched end 15 snaps into place on the rail flange. However, the use with either form of gripping member of the appropriate form of tool 14 hereinabove described, in cooperation with a claw-bar fulcrumed on the rail head is preferable, since in this operation all thrusts are toward the rail. and there is no tendency to loosen spikes or otherwise disturb the anchorage for the rail.
