11 Claims.

This invention relates to supporting and retaining means for railway rails, and has particular reference to improvements in tie plate and rail retaining clip combination.

Generally speaking, the object of the invention is to provide tie plate and rail retaining clip combinations which are cheap and easy to make and easy to install and which, at the same time, are highly efficient in service and practically indestructible.

More particularly, the invention has in view to provide tie plate and rail retaining clip combinations in which the rail retaining clips are, or may be, of one-piece construction and are capable of very economical production from standard rod or bar material by a simple bending operation, or operations, and in which the tie plates are, or may be, of standard construction except that they are provided with holes which may readily, easily and economically be punched or otherwise formed therein to accommodate retaining leg portions of the clips.

Further, the invention has in View to provide for connecting the rail retaining clips with the tie plates simply by striking the clips to drive their retaining leg portions into the holes formed in the tie plates, and to provide for securely interlocking the clips with the plates against the possibility of their accidental separation from said plates, simply by inclining the tie plate holes, ,and the retaining leg portions of the clips, relative to each other.

With the foregoing and other objects in view,

which will become more fully apparent as the,

nature of the invention is better understood, the same consists in the novel tie plate and rail retaining clip combinations, and in the novel features of construction of the tie plates and the clips, as will be hereinafter more fully described, illustrated in the accompanying drawings and defined in the appended claims.

In the accompanying drawings, wherein like characters of reference denote corresponding parts in related views:

Figure 1 is a transverse section through a rail illustrating one practical embodiment of the present rail supporting tie plate and rail retaining clip combination.

Figure 2 is a plan view of the combination shown in Fig. 1.

Figure 3 is a side elevation of the combination shown in Fig. 1.

Figure 415 a view similar to Fig. 3 illustrating an alternative embodiment of the invention.

Figures 5, 6 and '7 are perspective views illustrating different practical embodiments of rail retaining clips having the general characteristics of the clips shown in Figs. 1 to 4.

Figure 8 is a perspective view of a clip and a tie plate according to another alternative embodiment of the invention; and

Figure 9 is a view similar to Fig. 8 illustrating still another alternative embodiment of the invention.

Referring to the drawings in detail, first with particular reference to the practical embodiment of the invention illustrated in Figs. 1 to 3, A designates, generally, a railway rail and B designates, generally, a tie plate which is understood to be secured upon the top of a cross tie and which has the rail A seated thereon in accordance with well known practice, the rail including, as usual, base flanges Ill, and the tie plate having rising therefrom, as usual, a pair of rail seat defining ribs H which cooperate with the edges of the base flanges ID of the rail to hold the latter against lateral movement.

An important feature of the present invention is that the tie plate 3 may be of any standard or other design and that the punching or the otherwise forming therethrough or therein of holes is all that is required to adapt said plate for use with the present rail retaining clips. In this connection and as illustrated in Figs. 1 to 3, a pair of holes [2, I2 are formed through said plate B outwardly of each of the ribs I l and the holes of each pair are spaced apart longitudinally of the tie plate and are disposed in downwardly converging relationship in a common vertical plane parallel to the rail l0. However, this disposition and relationship of said holes is not essential, but may be varied in many ways, as will hereinafter become apparent.

Two of the present rail retaining clips, each designated generally as C, are used with the tie plate B, one at each side of the rail A, and said clips are duplicates of each other, each being bent to shape from a single length of rod and comprising, according to the Figs. 1 to 3 embodiment of the invention, a substantially horizontally disposed, substantially V-shaped rail flange overlying portion l3 composed of a pair of outwardly diverging arms l4, l4 joined together at their inner ends, and a pair of legs l5, l5 extending downwardly in convergent relationship from, and as continuations of, the outer ends of said arms [4, M, respectively.

Preferably, but not necessarily, the spaced apart and the convergent relationship of the legs [5, [5 of eachclip is the same as the spaced apart and the convergent relationship of the holes I2, I2 of each pair. Moreover, the holes I2 and the rod from which the clips are formed preferably, but not necessarily, are of circular cross section and the holes preferably are only slightly larger in diameter than the legs I5, I5 so as to more or less snugly accommodate the latter. Finally, the rod comprising the clips is either inherently resilient, or the clips are suitably tempered after being formed, so that the legs I5, I5 may be sprung apart and, when sprung apart, will tend to return to their normal positions.

From the foregoing it is apparent that in order to apply any given clip C to one of tie plates B, all that is required is to spread apart the legs I5, I5 of the clip until the free or lower ends of said legs are spaced apart corresponding to the spacing of the upper ends of a related pair of holes I2, I2, to then enter the free or lower ends of said legs in said holes, and then to release said legs and tap the clip downwardly until the rail flange overlying portion I3 thereof is brought into contact with, or in desired spaced relationship to the top of the related rail flange Ill. Due to the tendency of the spread apart legs I 5, I5 to spring inwardly when released, and due to the downward and inward convergence of said legs and the holes I2, I2, only a very light blow, or blows, is required to drive the clip downwardly to its operative position. In fact it may be possible in some instances to apply the clips simply by shoving them downwardly by hand after their legs have once been spread apart, entered in the holes 1I2, I2 and released. Conversely, it is practically impossible, due to binding of the legs I5, -I5 against the walls defining the openings I2, I2, to remove an applied clip merely by exerting upward pressure upon the rail flange overlying portion I3 thereof. Therefore, the clip remains securely applied because the only clip loosening force exerted by the rail flange is upwardly against the portion I 3 of the clip. On the other hand, the clip may readilyand easily be removed by exert- :ing a spreading force upon the "legs I5, 15 simultaneously with exertion of an upward force upon the clip, and ,in this connection any suitable tool may be provided for exerting a spreading force upon the legs I 5, I5 whenever removal of a clip may bedesired. Further in this connection it is apparent that a removedclip is in :no way harmed by its removal. Therefore, the clips are capable of repeated application and removal. Moreover,

.when any given clip is applied to a tie plate with its more or less resilient .portion I3 overlying the flange of a rail seated on the tie plate, it is apparent that while the rail is held effectively on the tie plate, it is, at the same time, held yieldably so that there is no interference with passage through the rail of the natural wave motion to which it is subjected in service.

Figure 4 of the drawings illustrates a clip C which differs from the clips C of the Figs. 1 to 3 embodiment of the invention only in the respect that its legs I5, 15 diverage downwardly relative to each other. This, of course, requires that the-holes I2, I 2' in the tie plate '3' diverge downwardly. Otherwise, the tie plate and clip combination of Fig. 4 is structurally the same, and has the same mode of operation, as the tie plate and clip combination illustrated in Figs. 1 to 3.

Figure 4 not only illustrates that the legs of the present clips may-diverge downwardly, but, considered in the light of the downwardly converging clip legs :illustrated in Figs. 1 to 3, suggests that .therclip legsand the pairs of holes in the tie plate may have various other inclined dispositions relative to each other. It is apparent, for example, that one of the clip legs and one of the tie plate holes may be vertically disposed and the other may be inclined, either inwardly or outwardly relative thereto; or, that both of the clip legs and both of the tie plate holes may be inclined in the same general direction, one at a greater inclination than the other; or, that, as viewed from the front of the clip the legs thereof may be disposed in parallelism and one may be inclined inwardly and the other outwardly. In fact, it is apparent that the clip legs and the tie plate holes may be disposed relative to each other in many different manners, so long as they have an inclined relationship to each other, to accomplish the purpose of the invention.

As has heretofore been stated, removal of an applied clip cannot be effected simply by exerting upward pressure upon its rail flange overlying portion, but requires simultaneous lateral pressure upon its legs, depending upon the direction of inclination of its legs. In this connection, and to facilitate the use of a suitable tool for exerting lateral pressure upon the legs, Fig. 5 of the drawings illustrates that the clip arms, preferably but not necessarily, at their junction with the clip legs, may be formed with tool accommodating eyes I6. Onthe other hand, Fig. 6 illustrates that in cases where it is necessary to press the clip legs outwardly relative to each other, the clip arms may be formed simply with outwardly bowed tool accommodating formations I 6', and Fig. '7 illustrates that in cases where it is necessary to press the clip legs inwardly relative to each other,

the clip arms may be formed simply with inwardly bowed tool accommodating formations '8. In other words, the clip illustrated in Fig. 8

is the equivalent of two of the clips illustrated in either of Figs. 1 to 7 disposed in side to side relationship with their adjacent legs I5, I5 joined together at their lower ends and together forming the third leg of the clip intermediate the two outermost legs. A third hole I2 is, of course, formed in the tie plate to accommodate the said third leg of the clip and, as is apparent, the three legs and the three tie plate holes may have any suitable inclined relationship.

According to each of the Figs. 1 to 8 embodiments of the invention the clip is formed from rod and bar stock of circular cross section. Manifestly, however, the stock used may have any other suitable or desired cross section. In fact, instead of forming the clips from rod or bar stock, they may be formed from sheet metal, as will be apparent from the form of the invention illustrated in Fig. 9. According to Fig. 9 the clip a 1 of Fig. 9, the leg I8 is disposed outwardly of the legs l1, I1 and is inclined downwardly and inwardly relative to the legs ll.

Without further description it is thought that the features and advantages of the invention will be readily apparent to those skilled in the art, and it will of course be understood that changes in the form, proportion and minor details of construction may be resorted to, without departing from the spirit of the invention and scope of the appended claims.
