RAIL ANCHOR.

Application filed December 10, 1920, Serial No. 429,733. Renewed February 16, 1925.

To all whom it may concern: 7

Be it known that I, GEORGE H. CHAD- WELL, a citizen of the United States, residing at St. Louis, in the county of St. Louis and State of Missouri, have invented new and useful Improvements in Rail Anchors, of which the following is a specification.

This invention relates to rail anchors.

Among the objects of the invention is to provide an efficient rail anchor which may be readily attached to a rail without any preliminary preparation of the rail therefor.

Another object is to provide an improved tilting anchor which when supported entirely by the rail base will positively grip the rail as the same tends to creep.

Another object is to provide improved means for securing an anchor to a rail.

Another object is to provide an improved anchor which may be held securely in position on a rail without forming holes or apertures therein.

Another ob'ect anchor which is simple, inexpensive to manufacture, and easily and quickly attached to a rail.

Other objects and advantages will hereinafterappear.

' The views of the drawings are:

Fig. 1 is a perspective of the anchor, the clamp therefor being separate therefrom.

Fig. 2 is an end elevation of the anchor applied to a rail.

Fig. 3 is a top plan of the anchor applied to a rail.

Fig. l is a side elevation of the anchor applied to arail.

The anchorhas upper and lower jaws 1 and 2, a leg 3, a foot 4, and an arm 5, all of which are preferably integral and cast from malleable iron or steel.

The anchor is adapted to be applied to the side of a rail with the jaws embracing a'flange 6 of the rail base as shown in Figs. 2, 3, and 4, the upper'jaw l'being above and the lower jaw 2 below the flange.

The leg 3 extends downwardly from the jaws and near its lower end is provided with the foot 4 adapted to engage a tie to act as a fulcrum on whichthe anchor may tilt. The engaging surface ofthe foot 3 is forward of the upper end of the leg so that the u er and is. f ee t9 more after more is to provide an improved ment of the lower end is arrested by en gagement of the foot 4 with the tie. The

anchor is accordingly free to tilt with the foot actmg as a fulcrum.

' The jaws 1 and 2 and the leg 3 form the main body of the anchor. A reinforcing web 7 extends between the lower jaw 2 and the leg 3. The forward end of the upper jaw and the rear end of the lower jaw may be enlarged so as to give them increased strength where they impinge upon the rail base flange.

The arm or,base 5 which extends laterally beneath the rail base from the lower jaw 2 is adapted to be fastened to the rail base so the rail will carry the main body of the anchor forward when the foot 4 abuts a tie thereby causing the anchor to tilt.

The arm 5 adjacent the edge of the rail base flange 8 is provided with an aperture 9 for receiving a wedge 10. This wedge 10, whenrdriven into the aperture from beneath the arm 5, engages the edge of the rail base flange 8, thus drawing the jaws of the rail anchor firmly against the rail base flange 6- After the wedge has been thus positioned, the upper end thereof may be bent over as shown in Figs. 2 and 3 to engage the upper face of the rail base flange 8. A hammer or other suitable tool may be employed for driving the wedge 10 into the aperture 9 and for bending it over the rail base flange.

Thus the anchor may be securely fastened to the base of the rail and supported entirely thereby. An anchor fastened to a rail in this manner is securely positioned thereon so that it will move with the rail as th same tends to creep. In fact, the anchor' is so rigidly fastened to the rail base that positive tilting of the jaws thereof will take place when the depending leg abuts a tie as the rail tends to creep in the direction indicated bythe arrow in Fig. 4. Furth'er tendency'ofv the rail to creep causes the upper :end or jaw of the anchor to move forward therewith, but the lower end or leg 3 is retarded by the abutting tie. The anchor is accordingly tilted on a fulcrum formed by the foot 4 so that the forward end of'jaw 1 impinges upon the upper face of the rail base flange 6, and the rear end of jaw 2 impinges upon the lower face of this rail base fl g 'll e base is thus firmly preparation of the rail for receiving the anrhor is necessary.

The wedge, which may be made of malleable iron or steel, when being positioned, draws the jaws of the anchor into close relation with the rail base, and when the upper end of the wedge is bent over, as by striking same at one side with a hammer,

the anchor is rigidly attached tothe rail.

Since no preliminary preparation of the rail for receiving the anchor is necessary, the number of tools required and the labor involved, and consequently the expense of attaching the anchor, are reduced. Practically the only tool required in applying the anchor to a rail is a'hammer for driving the wedge into the opening 9 and bending same over the upper face of the rail base flange 8. I

The invention contained herein, while dislosed herein in but one embodiment, is, of course, susceptible of many different embodiments and adaptations.

The invention claimed is:

LA rail anchor comprising apair of jaws for gripping a rail base flange and having their points of engagement with opposite faces of the flange separated a relatively great distance in the direction of the length of the rail, a depending leg for engaging a cross-tie to tilt the jaws about a horizontal to cause them to increasingly grip the rail as the rail tends to creep, a lateral arm and a deformable wedge cooperating with the other rail base flange and the ar nto hold the anchor against displacement and insure positive tilting of the jaws. V

2; A rail anchor comprising a pair of jaws for grippingtherebetween a'rail base flange, a depending legto causethe jaws to tilt about a horizontal axis and increasingly grip the flange when the leg abuts a-tie as the rail tends to creep, a lateral arm having an aperture therein, and a deformable attacher for extending through the aperture and engaging the other rail base flange to hold the anchor in place and insure positive tiltingof the jaws when the leg abuts a tie. A rail anchor c'omprismg a pair of aws for gripping therebetween a rail base flange, a depending leg to cause the jaws to increasingly grip the flange when the'leg abuts a tie as the rail tends to creep, a lateral arm having an aperture therein, and a wedge adapted to be driven into the aperture and the upper end bent over the other rail base flange to hold the anchor in place and insure positive tilting of the jaws when the leg abuts a tie.

jaws for engaging and increasingly gripping arail base flange when tilted, a depencing ice for abuttin a tie to tilt the jaws as the rail tends to c; p, an arm extending laterally from the low r'j aw, and an attacher for en; the arm and having an upper portion bent over the other rail base flange to hold the anchor in place and insure thep-ositive tilting of the jaws.

A rail anchor comprising two parts, one part including a pair of jaws adapted to engage the rail base, the other part being movable through the said first part and adapted to be bent over another portion ot the rail base to hold the anchor in place.

6. In a rail anchor comprising a base and a pair of jaws adapted to grip the rail base, the base having an aperture therein, a wedge adapted to be driven through said aperture to engage the rail base and to be bent thereover to hold the anchor in position;

A rail anchor comprising a base having an opening therein, a pair of jaws for'gripping the rail integral with the base,- and a deformable member adapted to be driven upwardly through the opening in the base so as to hold the anchor in position on the rail.

8. A rail anchor comprising a base having an. aperture therein, a pair of jaws at one end thereof adapted to engage a rail flange, a wedge adapted to be driven through the aperture to engage the rail baseso as toeX- ert a clamping action of the jaws on the'base, the projecting portion of the wedge being adapted to be bent over the rail vbase to hold the anchor in position.

9. A. rail anchor'eomprising a basehaiving an opening therein, a pair at jaws integral with the base for gripping one flange of the rail, and .a deformable member adapted to be driven through the base opening and toward the rail so as to engage theopposite flange of the rail and hold the anchor-thereon.

In witness whereof, I have hereunto subs ribed my name. T'
