Patented Mar. 4, 1930 UNITED STATES PATENT OFFICE ARTHUR E. H. AND JACOB A. KYLE, LOS ANGELES, CALIFORNIA, ASSIGHOBS llO RAILWAY SUPPLY CORPORATION, A CORPORATION OF DELAWARE RAILWAY-BAIL ANCHOR Application filed August as, me. Serial No. 888,581.

This invention pertains to new and novel improvements in rail anchors formed from a single-piece of metal es ecially designed to be fixedly secured to the ase portion of a railway track rail, and in engagement with stationary parts of the railway road bed for the purpose of preventin longitudinal displacement of the track-ralls during the travel of the rolling stock thereover, said invention constituting an improvement on the rail anchor set forth in an application filed by us under date of July 3, 1929, hearing Serial No. 375,856.

The prime object of the invention is to pro 16 vide a simple, novel, durable, economical, ractical and eflicient rail anchor formed rom a single plate or bar of suitable high grade spring steel of the desired dimensions and possessing unusual stren h, which may be easily and readily applie to the base of a track rail and secure y maintained in its proper operative position thereon, and which will always effectively .grip and clamp the rail base and co-operate with a stationary part of the railway road bed to prevent the track rail from cree ing.

Another object of t e inventionis to so construct the novel and improved device that it will always'maintain the required resiliency and tension and exert an extremely tight grip and efl'ective 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 and clamping action is imparted thereto.

The foregoing and such other objects as may appear from the ensuing description are accomplished by the construction, formation, location and combination of the several parts hereinafter more fully described, illustrated by the accompanyin drawings, and particularly ointed out in t e claims appended hereto, it ing understood that slightvchanges in the precise form, proportions and minor details of the construction may be resorted to without departing from the spirit or sacrificing any of the advanta es of the invention. In the accompanying rawi forming a part of this specification it will seen that:

tached from the trac rail.

Figure 1 is a side elevation of the improved device embodying our invention, showin one end portion broken away, showing a trac rail in cross-section and the device attached to the base of said rail showing the position assumed by one of its clamping members before it is caused to clamp the adjacent edge of the rail.

Figure 2 is a longitudinal section, in part, of the anchor device, showing it clamped in operative position to the base of a track rail and showing the track rail in cross-section.

Figure 3 1s a pers ective of the device de- Figure 4 is a'plan showing the blank from which the anchor device is formed, and

Figure 5 is a cross-section thereof taken in the plane of the dotted lines 55, Fig. 4, lookmg in the direction of the arrow.

In the embodiment of our invention as illustrated it will be seen that the numeral 1 indicates a railway track rail, and 2 an underl ing cross-tie forming a stationary part 0 the railwa road bed and supporting the rail 1, the sai rail having a tendency to creep, when subjected tothe intense strain caused by the travel of the rolling stock thereover.

This improved and novel anchor is formed from any suitable or desirable metal, but is preferably formed from asingle piece or bar of high grade spring steel that is rolled with a reinforced portion 3 at each side of the bar where it is about five-eighthsof an inch thick, while its central portion from 4 to 4: is reduced to a thickness of about threeeighths of an inch, the said bar bein then cut into the desired or required length or forming the anchor such as is'shown in Fig. 4, for formin this particular type of anchor, shown in Fig. 3.

While our special ty e of rail anchor may be formed in any suita le or desirable manner, the bar 5 is preferably heated to a suitable degree, and by means of a suitable punching device the thinner central portion of the bar from 4 to 4' is sheared as slit rearwardly therethrough to the point 6, thus forming a resilient tongue member 7 between the reinforced Side portions 3, then the end 100 tlti portion of the tongux member is so compressed as to form an upward extension thereby forming an integral lip member 8, after which the heated blank is placed in suitable ,dies for forming the depending body portion 9 by drop forging or stamping, while the last step in its complete formation consists: in simply bending over the portion 10 into the formation shown to form. the upper overlapping portion of the jaw member 11.

- It will be readily perceived that when the anchor device is completely formed it consists of a jaw member ll provided with an upper portion 10 adapted to tightly clamp against the upper inclined face of the rail base at one side thereof, and a lower member 10 adapted to firmly contact with the lower face of the rail base, a depending body portion 9 having widened reinforced smooth sides, one side of which is adapted to rest in contact with a cross-tie, upwardly and outwardly curved reinforced portions 12, and between said reinforced portions is formed the resilient tongue member 7, provided at its outer end with the extended lip member 8 adapted to firmly grip into contact with the other edge of the rail base when the anchor is forced into its operative position.

It will be obvious that the Wide reinforced smooth side portions 3 of the anchor furnish unusual strength thereto and prevent breaking while being forced on the rail and at the same time present a smooth widened bearing surface against the cross-tie all along its-face where it is in contact with the tie, thus preventing the tie from being cut, damaged or defaced by the excessive pressure of the anchor against the tie during the passage of the rolling stock thereover.

lhe anchor device is first adjusted on the rail base by hand, with the lip member and face of the jaw member ll with a suitable sledge or hammer until it is caused to assume the position shown in Fig. 1 with the lip and tongue members under strong upward. spring tension, then by a sharp blow of sumcient strength with the sledge or maul at the point 13 the lip member 8 is made to pass the edge of the rail and snap upwardly into close and rigid contact therewith and will remain in its secured position until removed by force.

It will be readily evident that the rail anchor device formed in'the manner hereinbefore described possesses unusual strength and efficiency; that it will prevent cutting and damage to the cross-tie; that it is easily and economically produced, and may be readily applied to and disengaged from the base of the track rail.

aving thus described our invtion what masses we claim and desire to secure by Letters Patent is:

1. A single piece rail anchor formed with a thickened reinforced portion at each side, an intermediate thinner portion forming a resilent tongue member, and a clamping jaw formed at each end portion thereof. Y

2. A rail anchor formed from a single bar of high grade steel having a thickened reinforced portion at each side thereof throughout its length, and a thinnerintermediate slit end portion, said tongue member having an upward extension formed at its outer end forming a clamping member.

a. A rail anchor of the character described, comprising a single piece of metal formed with a thickened reinforced portion at each side throughout its length, a depending body portion, an intermediate resilient tongue member, and aclamping member formed at each end portion thereo 5. A rail anchor for track rails of the character described, comprising a single bar of metal formed with a thickened reinforced portion at each side throughout its length, and an intermediate slit portion forming a resilient tongue member provided with a clamping member at its outer end.

6. A rail anchor for track rails, comprising a single bar of metal formed with an overlapping clamping member at one end portion, a thickened reinforced portion formed along the sides thereof, a thinner intermediate portion forming a resilient tongue member at the other end portion, a depending body portion and an upward extension forming a clamping member at the outer endof said tongue'member.

7. A rail anchor for track rails, comprising a single piece of high grade spring steel formed with a thickened reinforced portion at each side throughout its length, an overlapping jaw member formed at one end, a depending body portion intermediate its ends, and a thinner slit portion intermediate its sides forming a resilient tongue member having a clamping member formed at its outer end disposed between the reinforced sides.
