Application filed December 1, 1921.

anchors or clips to hold a lrail, frog or the 7 like to a base plate, rail plate or other structure.

The primary object is to provide an anchor 0r clip applicable ,to a standard tie plate to connect a rail thereto and tend to hold the rail against longitudinal movement relatively to the plate.

A further object is to provide a device which will not become loosened by vibration nor' by wave movement of the rail due to a train moving thereover.

A still further object is to provide a device a simple form, small size and light weight which may be easily and cheaply manufactured and sold at low cost.

Another object is to provide a device which may be easily assembled on or removed from a rail, but which will be substantially proof against removal by an accidental blow. 7

Still another object is to provide a device which may be assembled apart from a rail or plate without foreign connecting means, so as tobe handled as a unit in transport and distribution and which may be easily and quickly taken apart for application to a rail.

An additional object is to provide a device which may be attached without the use of special tools other than those ordinarily used in track laying.

One more object is to provide a device which is applicable without adjustment to practically all sizes of rails or at least to a very wide range of sizes.

The invention comprises a resilient plate or clip of any suitable form adapted to bear downwardly on the base of a rail and on the plate carrying the rail, a hook member to engage both the clip and the rail supporting plate, and an adjustable key to secure the hook and clip together.

Serial No. 519,201.

In the following description and accompanying drawings, the invention is descrlbed and shown only in connection with a rail and a tie plate but it will be understood that this is purely for purposes of explanation and is in no way limitative, as the invention has a much wider application.

In the drawings which illustrate the application of the invention to a rail and tie plate Fig. 1 is an end elevation.

Fig. 2 is a side elevation.

Fig. 3 is a plan view of the anchor in positiolp.

ig. 4 is a bottom plan View plate alone.

Fig. 5 is an end elevation of an alterna tive form.

Fig. 6 is a side elevation of the form shown in Figure 5.

Referring more particularly to the drawings, 11 designates a tie plate of any suitable pattern provided with holes 12 for the passage of spikes 13 to secure the plate to a tie and also to hold the rail down on the plate.

According to the present invention, the anchor or clip comprises a plate or strip 14 of spring steel bent intermediate its ends, as at 15, roughly to U-shape, to provide a long arm 16 and a short arm 17. The end of the clip in the arm 17 is notched out inof the clip 'termed iate the side edges providing an opening 18 and the metal displaced in forming this notch is turned away from the arm 16 to form a tongue 19 substantially normal to the arm 17. The arm 16 is provided with an opening 20, the innermost edge of which substantially aligns with the bottom of the notch 18. The clip arm 16 is not necessarily straight but may be provided with a slight initial curvature located preferably midway betweenv the inner and outer edges of the notch 20, as clearly shown in Figure 1.

The short arm 17 of the clip plate is adapted to lie upon a tie plate, with the tongue 19 depending through a spike hole of the plate, and the end portion of the arm 16 is adapted to lie upon the upper surface of a rail base.

In order to secure the plate 14 in position, a double hook member 21 is provided having at one end a spear-shaped end portion 22 having what may be termed barbs 23 and latter with the lower extremity of the tongue 19. The body of the member 21 is of such thickness that when lying close against the tongue 19, the two will just fill a spike hole 12. The body of the hook member passes through the inner portion of the opening 20 in a substantially Vertical direction and is then turned upon itself at 25 to provide a depending arm or hook 26, the extremity of which passes through the outer portion'of the openlng 20 and into or substantially into engagement with the upper surface of a rail base. The tongue 19 and hook member 21 are of such width that they completely fill the spike hole 12. It will be observed that the barb or hook 23 projects a considerable distance under the tie plate and so obtains avery good grip, the security of which is assured by the tongue 19 filling the spike hole and preventing the hook member backing away from the plate.

The hook and clip are connected and held in place by a wedge-shaped key 27, both long edges of which are rounded transversely of the key, as will be clearly seen in Fi re 1. The upper edge of the key is. provided with a plurality of uniformly spaced shallow notches 28, which co-operate with the slight curvature of the member 21 at the bend 25in the driving direction of the key,

which curvature it is well understood will follow naturally fromthe bending of the member 21 or which ma 'be specially provided during the formatlon of the bend 25.

The modified form of the invention shown in. Figures 5 and 6 differs from the form already described chiefly in the shape of the clipmember. The long arm of this member,

designated 16*, is substantially the same as in the previously described form but the short arm 17, instead of lying approximately parallel with the .long arm, is disposed approximately at right anglesthereto and is in end abuttmg relation with the tie plate. Owing to the different disposition ofthe arm 17*, there can be no tongue tOIllOld the hook member in. position. This is efl'ect ed by meansof a special spike 19 driven through the hole 12 in the plate outside the hook member. The hook member itself is of the same form as previously described, except that it lacks the second bar 24. v The key is exactly the same as previously de scribed. In the event that it is desired to provide a special tie plate and to use a standard spike in plane of the spike 19, the arm 17 may be bifurcated at its end, as at 29, to make provision for the spike head unless of course the arm 17 is positioned a suflicient distance from the spike hole to give clearance for the spike head. 0

The application of the device is extremely simple. A tie plate and rail being in 081- tion, the hook member is driven own through the selected spike hole until the extremity. of the hook 26 engages or substantially engages the top of the rail base. The sharpened point of the member makes this driving a very easy matter. The hook member is now moved toward the rail, so as to engage the barb or hook 23 thereof under the tie plate. This movement is effected by driving a spike into the spike hole on the opposite side of the hook member from the rail. The inclined surface of the hook 23 forces the same up against the tie plate during the lateral movement. In the ,case of the standard spike replacing it will serve to move the hook member as desired. The clip plate is now dropped over the hook member, so that it bears at one end on the top of the rail base and at the opposite end on the tie plate at each side of the spike hole. In the form shown in Figure 1, the. tongue 19 drops into the spike hole outside the hook member and holds the hook member in position, the chamfer 29 on the end ofthe tongue facilitating'its insertion and eliminating any downwardly presented surface which might bear against a tie and resist downward movement of the clip. In the case of the form shown in Figure 1, the relation of the arms 16 and 17 to one another 'is preferably such that the bearing above The ke is now-inserted small end first between t e bend or loop 25 and the plate and with its notched edge remote from the plate.

The key is now driven as tightly as desired and, by the wedging action which it exerts, presses down on the clip plate and draws up on the hook member. This pressarms and the surfaces which-they engage. I

ing down of the plate flexes the same, so that i it obtains a substantial surface bearing on the rail base at the extremity of the long arm and, in the case of the form shown in Figure 1, an equally'substantial bearing on arm. It will readily be seen that in this tightening action, substantially the whole length of the plate is flexed and is active as a spring. The'upward pull on the hook member draws its barb 23 very tightly .against the under surface of the tie plate.

The operation of the devic as a clip or anchor is as follows ;The downward pressure of the cli holds the same very tightly to therail an at the same time holds the rail down on the tie plate, while'the hook the tie plate at the extremity of its short member holds the cli to the tie aw The resilient nature of the clip, which permits it to flex slightly, avoids breakage due to vibration, sudden shocks or wave motion in the rail and, by reason of this resiliency, the clip remains always .in tight engagement with the rail. The hook member holds the clip against movement relatively to the tie plate in the longitudinal direction of the rail and the frictional engagement bet-ween the clip and rail tends to hold the rail against the longitudinal movement imparted to it py a. moving train or from other causes.

hen the key is driven tight, the tongue 19 or the spike 19* holds the barb 23 a ainst backing away from and disengaging t e tie plate, while at the same time the engagement of the hook 26 in the clip opening 20 prevents the hOOk'fIOIlI being opened by the tension. '11:" the clip should break, the extremity of this hook 26 will constitute a holding down member for the rail and the hook member a connection; between the rail and tie plate. The head 22 of the hook member is prevented from bending or tipping with consequent tendency to disengage its barb 23 from the tie plate, by reason of the engagement of the barb 24 under the tongue 19; This engagement also provides for the tensioning or flexing of the clip plate between the two ends of .the hook member, so that the device may be assembled and handled as a unit in transportation and distribution. The notches on the upper edge of the key serve to hold-the key against backing out and also serve as a guide to indicate how far the key should be driven for different sizes of rails. The resiliency of the clip plate renders the device adjustable to a wide range of rail sizes, so that the device may beused on practically any size of rail in general use. Preferably, however,

, placement bya chance blow in the line of,

with a. view to securing thebest results, the device will b8? made in a variety of sizes. The difference in the device for difl'erent sizes of rails may be confined to the key member '27 but, if unusually thin or thick plates are used under the rail, it will of.

course be necessary to provide a special hook member but, under ordinary circumstances, the hook member may be standard. for all sizes. It will be understood, however, that the variation may be efiected in other ways.

The advantages of the. device are numerous and will be manifest to anyone skilled in the art. It will be apparent thatthe load is disposed symmetrically and equally on both sides of the spike hole, so

that the hook member is supported on both sides by the clip plate and is not liable to disthe rail or by the driving of the key; The device provides a connection between {a rail or the like and which is rigid for all practical pu but plate thereunder The device may be applied to existing construction quite as easlly as to new construction. The device when applied on the inside of a rail will replace one of the spikes, as it holds the rail so securely to the plate that the plate becomes substantially a part of the base and the centre of oscillation is moved from the outside edge of the rail base to the outside edge of the plate, with the obvious result that a great additional upsetting force is necessary to tilt the rail outwardly.

While the invention has been shown and described as embodied in a construction in which the hook member turns inwardly at the top and bottom to overhang the rail base and underlie the rail support beneath the rail and in which the hook member passes through the plate, it will be understood that, while this arrangement is preferable, it is not essential and therefore that the invention contemplates the disposition of the hook member otherwise than passing through the plate and also the turning of the hooks otherwise than shown. The clip. or anchor has been illustrated as applied on the inner side of a rail but this is not obligatory and the clip may be used on the outer side if desired. Furthermore, while the device has been designed primarily for use as a rail anchor or clip, its use is not thus limited but the device may be applied to many other things where either temporary or quick release fastenings are required beween any two objects which may be connected by a device of this 7 construction.
