' RAIL FASTENING.

-F'iled Oct. 31, 1936 all Patented June 7, 1938 I UNITED ST TES PATENT OFFICE mm. FASTENING New Jersey Application October 31, 1936, Serial No. 108,668 4 Claims. '--(01. 238-349) be used to fasten the plate to the tie by means This invention relates to rail fastenings, and is particularly concerned with that type utilizing a spring metal rail-clip having its ends arranged to respectively press downwardly on the top of the base of the rail to be fastened and the top of the tie-plate ordinarily carrying this rail. Such a clip usually functions as a cantilever spring whereby the pressure that it can apply to the top of the base of the rail is limited. The present invention is intended to provide for the application of greater pressure to the top of the base of the rail than is possible in the case of such a clip, while retaining the simplicity resulting from the. use of the latter. according to the principles of the present invention possesses other advantages which will become apparent from the following.

An example of the invention is illustrated by the accompanying drawing, in which:

Figure 1 is a plan of a rail fastening embodying the features of the present invention.

Figure 2-is-a cross-section. 1 Figures 3' through 5 are, respectively, plan. elevation and perspective :views of details. Y A tie-plate I of the usual construction, having spike holes 2, carries the rail 3 to be fastened. The holes 2 are, of course, formed, 'at least in some instances, so as to be at least adjacent the edge of the base of the rail 2.

The clip 4 is made of spring metal and is of an elongated ,U'-shaped form. It is particularly characterized by being arched continuously throughout its length. That is/to say, no portion of the clip is straight or reversely curved so as to function as a cantilever spring, the idea being that the clip should function as an arch whereby both its ends must spring when either is stressed. The legs of this clip are outwardly offset, as at 5, to provide a rectangular opening 6. The clip-is shown with its closed end resting on the top of the tie-plate, but-this isfmerely forillustrative purposes.

If desired, wedges or bearing plates may be inserted between the ends of the clip and the elements against which they press.

Pressure is applied to the top of the clip 4 by a bolt 1 having a hooked end 8 which may be inserted through one of the spike holes 2 and hooked beneath the bottom of the plate 1. This bolt has a threaded'end 9 and its shank is rectangular so as to fittheopening 6 provided by .the ofisets 5 in the legs of the clip 4. The end 8 may be made so that a conventional tie-plate may be used, it being remembered that four spike holes are ordinarily provided whereby two' may The fastener constructed ID, a washer H is inserted between this nut and the clip. This washer is in the form of a flat rectangle having an opening l2 that fits the rectangular shank of the bolt 1 and depending flanges I! that embrace the edges of the offsets 5 in the legs of the clip 4'. Furthermore, a rib I4 is formed in the top of this washer while a correspondingly shaped depression I5 is formed in the bottom of the hut 10. The rib l4 and de-' pression II are constructed to provide rounded surfaces whereby forceful turning of the nut It can cause disengagement of this rib and recess upon springing of the clip 4.

' When a wheel passes over the rail 3 in such a manner as to cause upward deflection of the latter, both ends of the clip 4 exert a springing action. If necessary. the bolt 1 can pivot slightly about its hooked end Q to equalize the stresses involved. It is obvious that there is no danger of the nut l0 becoming loose in service. Finally, due to the arched construction of the clip 4 and the central application of the pressure to this clip, more pressure can be applied to the top of the base of the rail 3 than can be done by means of a spring clip functioning as a cantilever spring. It is taken for granted that the reader will understand that the hooked end 8 of the bolt I can be accommodated by slightly notching the topof the tie beneath the plate I.

We claim:

1. A rail fastening including a tie-plate for carrying the rail to be fastened and in which a hole is formed so as to be at least adjacent the edge of the base of said rail, an elongated U-shaped .through said hole and hooked into engagement with said plate, said bolt having a threaded upper end and a rectangular shank adapted to fit through said opening of said clip. a nut for said upper end of said bolt and a flat washer for insertion between said clip and said nut and having upon forced rotation of said not and springing of said clip.

2. A rail fastening including an elongated upwardly arched U-shaped spring metal clip for holding a rail down on suitable support and having its legs offset outwardly at one portion to provide a fastening element passage and a fastening element adapted to pass through said passage and apply downward pressure on said clip.

3. A rail fastening including an elongated upward ly arched U-shaped spring metal clip for holding a rail down on suitable support and having its legs offset outwardly at one portion to provide a fastening element passage and a fastening element adapted'to pass through said passage and applydownward pressure on said clip, said fastening element havingva non-circular shank portion and said passage provided by said oflset legs being shaped to fit said shank portion.

4. A rail fastening including a tie-plate for carrying the rail to be fastened and in which a hole is formed so as to beat least adjacent the edge of the base of said rail, an elongated upwardly arched. U-shaped spring metal rail clip that has its legs offset outwardly to provide a feetangular opening, one end of said clip being' through said hole in engagement with said plate,

said bolt having a threaded upper end and a rectangular shank adaptedto fit through said opening of said clip, a nut for said upper end of said bolt and a flat washer for insertion between said clip and said nut and having flanges'adapted to embrace the outside of the legs of said clip, the adjacent surfaces of said nut and-said washer providing interfltting projections and depressions which can be disengaged upon forced rotation of said nut and springing of said clip.
