Serial K012352368;

7 Myin 'ention relates to rail anchors and relates particularly to rail anchors of the general type having a rail base grip-ping element and a reach bar pro3ected ther'eironl transversely andbeneaththe ra1l base to engage the oppos te ra l base edge to lock the anchor onithe rail.

TlllS inventlon has for improvement of that typeof rail anchor making wedging engagement. with, the clamp to cooperatetherewith to lotzkthe anchor on the raiL r 7. An object of lmyinvention isto proyidea highly eliici-ent; form of anchor which maybe advantageously manufactured in at smallcost. a i Another object ofimy invention is to proide a two piece anchor employing a rigid clamp 77a nd resilient clip,

Referring nowtoall of r the figures of drawing in all of which like parts are des-7 ignatedby like referencecharacters, I show generally atl inFigs. '1 to 4 and in Fig. 5 a relatively rigid clainpniade of sheet steel to: take the ftorin illustra-ted in the figures.

At 12, I show the relatiyely resilient clip which is formed frolnasingle length of bar steeh as by successive eutting and it'orgin'g yoperations; The'clip QpB-eterably comprises a reach arm 3 terminating at one end in an lip-turned hook {l and at the other end in loop 5, the loop-being formed by reversely turninga relatively short arm l6 toward the" intermediate portion of the reach arm 73,

forming the otherqarmof the loop."

byfthe converging of the short arnil toward the intermediate porti oniofthe long or reach Tll6- Cl2t1l1p is in the form of a pierced channel havingaf rearwall 77 and sidewalls 8 7 and 9. The upperend' of the clamp" is folded at a substantially acute angle to the'pendant portion extending over an'd beyond the" side walls 8 and 910i? thechannel, whose upper portions are deflected "outwardly and cur'vi-' The loop is normally open and adaptedto "be closed linearly to merge with thetop portion ofthe .ClELlIlP, whiclris inrthe forniwof a pair of spaced lOngltllltllllitll 7BXlGndlllg arches 10 Land 11, interiorlyjoined by-adepressedlon- 7gitudinallyextending trough portion 12. 7 Thus, there isfgiyen to theupper the clamp a: substantially M-fOI'llllD. trans verse sections with an outward 'an'd rearward bulging of the curvilinearly. formed portions 7 13, jqiningthe eendant channel with the upper parto'f the clamp, the rea r 'wallof the clamp comprising the rear channel "wall j7 and the rear end 14 of the jJ'oiningpartlB is propart of vided with a preferably rectangular aperture 15 extending downwardly from the wall 12 of the said intermediate trough portion of the clamp to substantially below the middle of the rear channel wall 7.

Somewhat above the level of the lower edge of the aperture 15 tongues 16 and 17 are projected inwardly from the material of the side channel walls 8 and 9 of the channel toward each other, as to form shelf elements.

The lower-most surfaces of the said 'forwardly deflected upper part of the clamp comprises the parts 10, 11 and 12 form spaced. jaw portions 18, 19 and 20 engageable with the upper surface of a rail base flange A onto which the clamp may be driven as illustrated in Fig. 1, the upper edge portions 21 and 22 of the said joining parts of the clamp, which are upwardly and outwardly extending portions of the channel walls 8 and 9, forming a pair. of spaced lower jaw elements engageable with the bottom surfaces of the said rail base flange.

Thus, the blank 1 is adapted to be driven onto a rail base flange, the ancillary spaced jaw elements 20, 19 and 18 engaging the top of the rail base flange while the ancillary spaced jaws 21 and 22 engage the bottom surface of the rail base flange A as best shown in Fig. 4, these opposing sets of jaws defining a tapered jaw opening adapted to rigidly secure the rail base flange between the sets of jaws.

The material of the clamp and the disposition of the material is such that a slight amount of yieldingmay be accomplished as may be necessary to insure a tight flt of the clamp onto the rail base flange.

The clip is adapted to be projected through the aperture 15 and over the shelf elements 16 and 17, which are engaged by the short arm 6 of the clip, the hooked end 4 of which being projected foremost until it is brought into engagement with the under surface of the base of the rail between which and the shelf elements the loop 5 by its long and short arms will make wedging engagement.

Such insertion of the clip through the clamp will preferably be made after the clamp has been driven onto the rail base grips by its opposing sets of flange which it jaws above described.

The clip is now driven home by striking the end 240i the loop with a maul or other implement, compression of the loop 5 result-' ingwhile the hook 4: is advanced to the other side of the rail until it reaches a position where it will snapnpwardly into abutting lateral engagement with the lateral surface of the rail base flange B. v

The rail base now tightly gripped by the opposing jaws of the clamp which embrace the rail base flange 23 and the shoulder lat member,

' clip.

the end of the clip engaging the lateral surface of the flange B.

lVhen in position, the reach arm 3 of the clip forced to take a less bowed form, being straightened somewhat by the upward pressure of the end 26 of the short arm (5 against its underside, the short arm being supported in reach arm supporting position, meanwhile, by the shelf elements 16 and 17 and retained in such position by the engagement of the shoulder 4 with the rail base flange.

The width of the aperture 15 and the spacing between the walls 8 and 9 of the. clamp is just enough greater than the width of the bar forn'ling the clip, that the clip may be readily inserted through the clamp but, and at the same time are adapted for engagement with both sides of the clip to prevent rotational movement tending to displacement of the clip. Y

Either of the outer lateral surfaces of the clamp walls 8 or 9 is adapted for engagement by a rail tie shown at 27' to form an abu ment for the anchor to prevent longitudinal displacei'nent of the rail relative to such tie or other fixed portion of the railroad bed which it abuts.

Having thus described my invention in certain embodiments, I am aware that numerous and extensive departures may be made from the embodiment illustrated and described herein, but without departing from the spirit of my invention.

I claim:
