- TWO-PIECE RAIL ANCHOR;

. As is well known by those engaged in railroad operation, the general causes of ra1l creeping are: thewave motion of the track. under the alternate; application and release.

5 of a rolling load; the application of the brake, especially, when the wheels slide; curvature of the track when the velocity of .the train'is'greater or less. than the velocity for'which the Outer rail is elevated; and

descending grades. sively on brldges- Rails creep also exces- The general object of my invention is the provision of an improved device which when several thereofare combined with the track rails and cross ties will prevent the creeping or longitudinal movement of the'rails relative to the ties under traflic. Itsfunction: is

to-hold the rail in a fixed position relative to the tie so that the force which causes creeping of the rail will be transmitted through both the rail and tie to the track ballast.

. The specific object is the provision of such a device which shall be simple in construe tionin two pieces.-cheaply produced, and 1 easily applied, and which shall be adapted. I

The invention consists in the construction and in the combination of parts as'lierein set forth and claimed.-

Theaccompanying drawing illustrates an example of the embodiment of the invention,

the parts being constructed, formed, and

combined according to the best mode of prov cedure I have so far devised for'the purpose.

driven, as hereinafter described, into engagement with the wedge member.

The

body ofsthebaris bent at the point 135 that thesu'rfaces to the left and right of said point will lie in difierentplanes angularly disposed to each other; However, if desired,

the anchor bar may be made of resilient metals or of cast metal cast to the shape shown'by Figured. 1

The wedging device, Figure 3, consists of a body portion U-shaped in cross section having'the two-flanges 9; and 11, and the bearing flange 12 disposed at one end of the body portion and at a right angle thereto. The outer surface of the flange 12 is plain andis adapted to frictionally engage the vertical surface of the tie.

Special attention is called to the wedging surfaces of the wedging'device. 1The'bottom surface of flange 9 is inclined transversely of the wedge members so as to correspond with; substantially the inclined portion 13 of the anchor bar. The said lower surface of said flange alsotapers longitudinally of thewedgeanembenthat is to say, from the liquelydisposed with relation to the vertical plane of the bearing flange 12. v c v To apply the'device to a'rail, the anchor bar is preferably passed over the end of the rail to the desired position. It will be obvious, however, thatthe proportions of the Tyokemay be varied so that it may be hooked 1 over therail base, in a -manner well understood,aat points intermediate the ends of the rail. The wedging device is placed with the bearing flangeabutting the tie. The end 15 of the bar is then slipped over the free end of the wedging device as far as it will go-without the ,application of much force.

The bar is then driven by a sledge to the relative position shown byFigure 1. In driving the bar to its seat the following actions take place: asthej lower inclined surface of flange 9 engages the offset 18 of the anchor bar the portion 18 is forced downwardly and causes a longitudinal twisting of the bar so that the opposite inner sharp edges of the turned-over end 14 engage the upper and lower surfaces respectively of the rail flange and bite into the metal, producing a grip .tha t is generally known as a shackle grip on the top and bottom surfaceslof the rail base flange. The action is the same at the end of the bar relative to the top and bottom surfaces of the body portion of the wedging device. he inclined surface 10 of the wedge member draws the bar member in the direction of its length across the rail base, and

, 5. The Subject-matter of claim 4c wherein the device is provided with a flange to engage a cross tie.

6. The combination in. an, anchoring device, of a bar with lhookedendsand"a" lever i oifset1 8 inthe body or the bar disposed forces the end 14 of the bar uponthe adjai cent; flange of the rail; This wedging action also expands the turned-over endl5 and insures a" powerful frictional grip which advances the U-shaped body of the wedging device upon the adjacent rail flange.

It will be noted i11-Figure 2 that the top I surface of the anchor bar at the left of the point 13 is in frictional c ontactwith the u11- "der, surface of the rail flange.

The offset 18 has the actionof a lever arm in twlst ng the anchor bar, which is an im- ;portant function in anchoring the device.

The inclined surface 10 also performs an 1mporta'nt' function in drawing the bar crosswise of the ra l. I

From the foregoing description it is clear that I have provideda'.two-piece rail anchor I last.

which is cheap in first cost, simple in construction and efficient in'operati'on'when applied in connection with a rail and tie;

A plurality of thedevices illustrated will e nnot move relative to the ties, consequently the force or forces whichcause c'reepin'g must be transmitted to several tiesat the same time and atfdifferent poi'nts, thus distributing the energy so that the rails and ties will not move relative to the track bal- 1.

2. The combmtion 1n an anchoring de-' vice, of a'barwith turned-over ends'and a lever, and a w dgihgdeVice provided with means engaging the lever for twistingthe bar. and also with means for-moving 'the bar at the same time crosswise ofther'ail.

7. A rail anchor comprising a rail base embracing member and a wedge member,'.the body surface of which inclines longitudinally of the rail when applied thereto andadapted to be forced between the bottom surface of the'rail base 'and the top surfaceof said embracing member, whereby the embracing member is subjected to a torsionalfstress to force one end thereof into shaclile'gripping engagement with the top and bottom 'surfaces of the rail base.

a flange to engage a tie and "an inclined surthe rail base; the said we'dger member being formed with a tapered bottom surfacefadapte'd tobear against the top'sur fa'ce of said bar, whereby the movement of said bar into gripping engagement with the saidwedge member subjectsjthe body portion to. a torsional stress and moves the hooked end portion at one end of the anchor into gripp ng engagement with the top-and bottom'sur 10. A rail anchor consisting ofa rail base embracing bar for engagement with one edge of a rail base and the upper surface of; said I bar being normally parallel, longitudinally of the rail, with the under surfaceiof saitl 11111 132188, and a we'dgi'ng 'member'formed with a tapered bottom surfaceadapted to be driven between the rail'base andsaiid top surface of said embracing. bar, whereby said embracing-bar is'flexed to move said top surface thereof into flat i gripping? engagement with the tapered surface of said wedge member.
