Application led July 20,

.provide means whereby an anchor device of the above character made to t a rail base of one size may be applied to a rail having a base Harige of a different size or contour. In this connection, I contemplate as a more specific object, the provision of means which movement of the anchor device and thereby avoid excessive lspreadin of the rail gripping portions of the'anc or; which means cannot be removed during the application of the anchor or after it has been driven to its applied position on a rail; and which, when the device is applied to a relatively narrow "base `iange, will prevent the anchor fromV which isrelativelyy narrow and thick withskewing about a vertical axis to an objectionable angle, but which will serve to increase the grip of the device onthe rail when the anchor is subjected to a moderate skewing action.

The invention has for further objects the new and improved construction, arrangements, and vcombinations of parts hereinfter described and claimed for carrying out the above stated objects and such other objects as will appear `from the following description of the two specific embodiments shown in the accompanying drawing.

In the drawing:

Fig. 1 shows a one-piece anchor device, of a type now in general use, made ofsuch `di; mensions as to it a rail base of a predetermined width and thickness.

Fig. 2 shows the same anchor device in connection with one embodiment of my'improved stop member applied to a rail base respect to the rail base shown in Fig. 1.y

Fig. 3 is a view similar to Fig. 2 showing the samev anchor device andamodied form of stop member applied to arail .base which is bothnarrower and thinnerthan the rail base shown in Fig. 1. "`Fig."4 is a sectional view taken on line 4-4of Fig. 2, and Y Fig. 5 is a view in perspective ofthe stop member shown in Fig. 3.

In order to illustrate the principles embodying my invention and the advantages to tion to other rails.

1927. Serial No. 297,195.

beV obtained by itsy use, `I have illustrated i herein a one-piece rail embracing member applied to rail b ases of three different sizes. It should be understood, however, that the form of anchor device 10, herein showm'is employed merely for the .purpose of illustration and that various otherf'o'rms dof rail embracing members may be used instead of the form herein shown. A Y i The rail embracing member 10 consists of a bar formed at one end with aV hooked'jaw portionv 11 adapted'to be driven intoigrip- `ping engagement with the top andv bottom surfaces of the rail base and-is `formed at the other end with a shoulderV 12 which snaps Vover the opposite edge of the rail base `when the jaw end 11 hasbeen driven to its normal gripping v position `on the rail" base. `the particular form offrail embracing member herein shown, the grippingsurfaces 13 and- 13n of the jaw end of the member 10 are 'spread apart slightly by the movement of the member 10 toits rail-gripping position so as to exert spring pressure on the top and bottom surfaces of the rail base. This spring action of the jaw end'll serves also to sive distortion tends to make a permanent set inthe distorted portion, and thereby makes the anchor unsuitable for rfc-,applica- InV order to avoid these conditions the one-piece type of anchor is ordinarily made to iit a rail base/of predetermined size and cross-sectional contour.

Rails of different standard contours, but of A the same Weight per linear yard, may differ appear at substantially the same distance from the' opposite side of the rail base.

My present invention .aims to take adi vantage of the above conditionsby providing a separately formed member 14 adapted to be positioned-in the jaw portion 11 of `)aw 11, but the down-turned ends 15 and 16 are of sufiicient length to prevent removal of the member 14 when the jaw 11"L is hooked over lthe edge of the rail base. The width of the member 14 is such that it comes into contact with the edge 17 of the rail base 18 and prevents any substantial further movement of the member`10 as soon as the shoulder 12 snaps over the opposite edge of the rail base.

7 The rail embracing member herein shown is made to fit the rail base 19, shown in Fig.

1, and is applied by hooking the jaw 11"l over the base ange at one side of the rail and then driving the member 10 transversely of the rail by striking the jaw end 11 with a Sledge or suitable applying implement until `18v and 19 at theshoulder 12 snaps over the opposite edge of the rail base. In this connection, it will be noted that both of the rail bases shown in Figs. 1 and 2, are of substantially the same thickness m at substantially the same distance Y from the opposite edge of the base. It will therefore be seen from an inspection of Figs. 41 and 2 of the drawing,

that by inserting the member 14 in the jaw end 11 of the embracing member 10, driving the jaw portion onto the narrower base 18, the member 14 will serve to limit the applying movement of the member 10 so that the shoulder 12 will snap over the edge 20 of the base 18 when the gripping surfaces 13 and 13 reach their intended gripping position. v It will also Ibe noted that the said gripping surfaces will grip the base flanges points of substantiallyV equal thickness. The stop member 14 bearing against the vertical surface 17 of the base 18 will prevent any substantial skewing of the anchor about a vertical axis. The clearvance 21 in Fig. 1 and the clearance 22 between the stop member 14 and the root of the jaw portion 11 in Fig. 2, permit the an- Chor to be'applied to slightly oversized rails,

-such,'for example, as may result from the wearing ofor the adjustment of the rolls with which the rails are formed.

In Fig. 5, I havelshown a modified embodiment in which the stop member 14u in addition to having flanges 15, 16, which fit over the side faces of the rail embracing member, is formed also with an extension 23, intended to fit between the bearing surface 13 of jaw 11 and the top inclined sur- Lesa-137 face of a relatively narrow and somewhat thinner base flange than that for which the member 10 was made. lVith this form of clip member, the embracing member 10 may be applied to rails having base iianges of less thickness than either of the rails 18 and 19, shown in Figs. 1 and 2.
