BAIL-ANCHOR.

Application filed. June 15, 1917. Serial No. 174,966.

To all whom it may concern:

Be it known that 1, CHARLES F. CLAWSON, a citizen of the United States, residing at Mount Pleasant, in the county of Henry and State of Iowa, have invented certain new and useful Improvements in Rail-Anchors; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same,

My invention relates to that class of devices designed for preventing creeping of railway rails. The object of the invention is to provide an extremely simple and inexpensive device for this purpose having ample space for driving the locking wedge the required amount without permitting it to abut the tie and having improved means to prevent angling of the anchor while said wedge is being driven.

Vith the foregoing general object in view, the invention resides in the specific construction and arrangement of parts to be hereinafter fully described and claimed, the descriptive matter being supplemented by the accompanying drawing which constitutes a part of this specification and in which:

Figure 1 is a top plan view of the device showing the same applied to a rail with the latter shown in horizontal section;

Fig. 2 is a longitudinal section of the anchor and a transverse section of the rail on the plane indicated by the line 22 of Fig. 3 is a vertical transverse section of the anchor on the plane of the line 3-3 of Fig. 2;

Fig. 4 is a perspective view of the base plate; and,

Fig. 5 is 'a. similar view of the wedge member.

In the drawings above briefly described, the numeral 1 has reference to a substantially T-shaped base plate adapted to extend transversely beneath the rail R, the shanlr 2 of said plate having on its free end a hook 3 formed integrally therewith to receive one base flange of said rail, the bill of said hook having formed integrally therewith a flat wing a extending longitudinally therefrom to overlie said flange as shown in Fig. 2, the free end of said flange being preferably increased in width and provided with a straight edge 5 to abut the web of the rail to prevent angling or canting of the bed plate when the wedge member is driven in place;

One end of the head 6 of the T-shaped base plate 1 is equipped with a transverse depending thrust fiange 7 adapted to abut a tie T as indicated in Fig. 1. A longitudinal flange 8 is formed integrally with and det pends from the outer longitudinal edge of the head 6 and at one end is joined integrally with the outer edge of the flange 7 to brace and reinforce the latter, said longitudinal flange having in its outer face a groove 9 extending throughout its length while the aforesaid longitudinal edge of the head 6 is provided on its upper side with a tapered rib 1O increasing in size toward the flange 7.

An elongated wedge member 11 of inverted L-shape in transverse section is provided, the horizontal flange 12 of said wedge member having in its lower face a tapered groove 13 to receive the rib 10 and an angular seat 1% to engage the base flange of the rail opposite that received in the hook 3. The vertical flange 15 of the wedge member 11 has formed on its inner face a longitudinal rib 16 received slidably in the groove 9.

The entire device is formed of but two castings and may thus be easily and inexpensively manufactured, yet will be highly eflicient and durable. Particular emphasis is laid upon the T-shaped formation of the base plate 1 to give sufficient length to the wedging rib 10 to permit driving of the wedge member 11 thereon to the extent necessary for producing the required clamping action upon the rail. in devices of similar nature having a comparatively short rib 10, the taper of the latter must be comparatively abrupt and thus the wedging actionis not as great. Furthermore, by having a long travel for the wedge member, there is no danger of driving the same past the base plate into contact with the tie as now often occurs with anchors of the type just referred to. Emphasis is also laid upon the fact that the flange 8 is joined integrally with the thrust flange 7 to brace and reinforce the latter and 113011 the orovision of the flat l wing d which prevents can-ting of the base plate while driving the wedge member 11. It is not any particular feature of the de vice, however, that I consider as my invention but the specific arrangement of parts for producing the advantages pointed out.

I claiin:

A. rail anchor comprising a substantially T-shaped base plate to extend transversely beneath the rail, the free end of the shank of said plate having formed integrally therewith a hook to receive one base flange of the rail, the bill of said hook having flatwing extending longitudinally therefrom in the plane thereof to overlie said base flange and the outer end of said wing being formed with a straight edge to abut the web of the rail to prevent angling of the base plate be neath said rail, a transverse thrust flange depending from and formed integrally with one end of the head of said base plate to abut a tie a longitudinal depending from and formed inteprallv with the outer edge of said head and integrally joined at one end to the outer edge ot said thrust i v 4- L L '1 range to biace the latter, saiolongitudinal flange having a groove in its outer face ex- Gopies of this patent may be obtained for five cents each. by addressing the Commissioner of Patents.

tending throughout its length, a tapered rib on the upper face of said head and extending longitudinally thereof along the outer edge of the same, said rib increasing in size toward said thrust flange, and an elongated wedge member of inverted L-shape in transverse section the lower side of the horizon tal flange of said wedge member having a tapered longitudinal groove receiving said tapered rib and the vertical flange of said member having on its inner :face a longitudinal rib received in the groove of said longitudinal flange.

In testimony whereof I have hereuntoset my hand in the presence of two subscribing witnesses.
