TWO-PIECE RAILWAY BA IL ANCHOR Application filed December 18, 1930. Serial No. 503,802.

This invention pertains'to new and novel improvements in rail anchors formed from two pieces ofhighgrade spring steel especially designed to be fixedly secured to l 15 the base portion of a railway track rail, and in engagement with stationary parts of the railway road bed for the purpose of prevent-- ing longitudinal displacement of the track rails during thetravel of the rolling stock thereover;

The prime object of theinvention is to provide a simple, novel, durable, practical, economical and thoroughly efiicient rail an- I chor of the desired and required dimensions possessing the requisite strength, which may be readily applied to'the base portion of a track rail and securely maintained in its proper operative position thereon, and which will always efiectively grip and clamp the rail base and cooperate with a stationary part ofthe railway road bed to prevent any creeping action ofthe track rail.

Another object of the invention is to so construct my improved two piece rail anchoring device that it will always maintain the required resiliency and tension and exert an extremely tight gripping, clamping and effective frictional engagement with the track rail under any and all conditions of service, and the greater the twisting strain to which the anchor may be subjected the more intense gripping power is imparted thereto.

The foregoing and such other objects as may appear from the ensuing description are accomplished by the construction, formation, locationamd combination of the several parts hereinafter more fully described, illustrated by the accompanying drawings, and particularly pointed out in the claimsappended hereto, it being understood that slight changes in the precise form, proportions and minor details ofthe construction may be resorted to without departing from the spirit or-sacrificingany of the advantages of the invention. V l p p 'In the accompanying drawings forming a part of the specification it will be seen that:

'- Figure 1 is a side elevation of the improved device embodying-my invention showing the relation thattheparts a e caused to assume with respect to the track rail when the said parts shall have been properly applied to said rail, showing the track rail in cross-section, and a cross-tie broken away.

Figure 2 is a plan showing a portion of the track rail broken away and partly in section with a portion of a cross-tie broken away.

Figure 3 is a similar plan showing the position assumed by the locking clip or key when first passed through the opening formed through one end portion of the main anchor member.

Figure 4 is a perspective of the main anchor member detached from the track rail.

Figure 5 is an inverted plan of the member 66 shown in Fig. 4.

Figure 6 is a side elevation of the securing clip or key detached from the track rail and main anchor member, and

Figure 7 is an inner end elevation of the 70 clip or'key as shown in Fig. 6.

In the embodiment of the invention as illustrated it will be seen that the numeral 1 indicates a railway track rail, and 2 an underlying cross-tie forming a stationary part 76 of the railway road bed and supporting the rail 1, the said rail having a tendency to creep or move longitudinally, when subjected to the intense strain caused by the travel of the rolling stock thereover.

The letter A designates the main anchoring member which may be formed from any suitable or desirable metal, but is preferably formed from a single bar of high grade steel of the required dimensions, the operation of 86 forming the said member being performed by drop forging or stamping the bar with a downwardly extended or depending U- shaped centrally disposed portion 3, having a flattened portion 4 extending from each 90 side of the upper end of said portion 3, the upper face of each flattened portion 4 being adapted to contact with the lower face of the track rail, while one end portion of the member is suitably bent upwardly and inwardly to form the upper portion of the jaw member 5 that is adapted to, overlap and tightly clamp against the upper inclined face of the base portion of said track rail, and the other end portion of said member 1 after described; I

. The letter B designates; the fastening clip .1

is provided with an opening 6 therethrough,

preferably of a substantially oblong contour,

said opening being so formed as to spread the surrounding metal, thereby producing an enlargement 7 at that end portion of the member to assureadditional strength thereto, while at the same end portion of this membervin its lower face is formed a depression or recess 8 for the purpose here1nor key formed with a somewhat bow-shaped central body portion havi'fig two outwardly extended portions 9 and 9 inclined inward.-

ly from each outer end to its inner end,'said" body portion being flattened at each side portion lo'thereof, while its inner and outer faces arerounded at'11,the diameter of the said clip or key being greatest at the center of the body portionat the point 12., The extension 9 is formed with a flat inner surface portion l3 'adapted to contact with the upper inclined surface of the track'rail base and its outer snrfaceis rounded, while the extension,9. s formed with a. rounded inner surface portion '14- adapted to be seated in the depression or recess 8 formed in the lower face ofmember A, and the outer surface is fiattenediand merges into the rounded surface of the said clip orlkey.

In the applicationjof the anchoring device to a trackrail the member A'is first applied to the by hand with fthevjaw member at one end resting on the upper surface of the inclined base portion of the rail at the outer. I edge of the said base portion, and said'memher is then forced'on vthebase striking the member at the point Qwith a suitable sledge or maulthus causing the overhanging jaw member to be forced up the inclined face of the base ,under extreme clamping tension until the opening'formedthrough its other end is-causedto be so disposcdthat the inner 1 wall of said opening will rest beneath the rail base, at a point'adj acent-to the outer edge of the rail base, as shown by the dotted lines,

. Figure 3, with. the flattened upper faces of the body portion 4 of said member in close contact i extended 'end portions 9 and 9 are caused to rest in the position shown by the dotted lines Fig, 2With its upper extensioni). resting near "the edge of the .railfbase and upon its. upper H with the lowerface of the rail base, the clip ,or key B sv then passed hand through the said openingand' caused to assume the position shown in Figure 3,.the said clipor key is thenjturned slightly by hand until its outer Qinclined surface, when byjstriking theou'ter face of the extension 9 with a suitable sledge "or maul the extension 9 is forced up the said Linclinedsurface untilnit is caused to. assume the position shown in Figsl and 2, said operation causing the lower extension 9 to simul-- taneously swin'gand rise beneath the rail base,

until is causedto assume aposition in vertical alinement with the upper extension 9, with the inner rounded face of the extension 9 resting within the depression or recess 8 formed in the member A'thereby securely retaining the clip or key in its locked positiomand at the same time the said clip or key-is being driven or forced into the locked position the rounded outer surface ofthe body portion of the key being in contact with the outer wall key. is forced into its horizontal positionxwith relation to said member A, the outer portion of the-memberis being forced outwardly until the inner wall of the opening is moved of the opening in. the member A, as the clip or, 7
