RAIL ancnon.

Application filed February 9, 1925. Serial No. 7,910.

To all whom it may concern.

Be it known that I, HAROLD G. WARR, a citizen of the United States, residing at Park Ridge, in the county of Cook and State of Illinois, have invented certain new and useful. Improvements in Rail Anchors, oi which'the following is a specification.

My invention relates to rail anchoring devices and has for its object to provide an improved rail anchor which will grip one of the base flanges of a rail with spring pressure and abut against a cross tie so as to resist any longitudinal creeping movement of the rail.

In this connection I contemplate a one-- piece anchor having a spring jaw portion adapted to grip one of the base flanges of the rail, and with a body portion adapted to snap into engagement with the opposlte edge of the rail base, so as to prevent the jaw portion from backing off the inclined surface of the rail base, which body portion is so formed that the anchor device will bear against a cross-tie at a substantial distance below the rail base so as to be suitable for use in connection with pole or hewed ties.

The invention has for further objects such other new and improved constructions as will be hereinafter described and claimed for carryin out the above stated objects and such 0t er objects as will. appear from the description of the embodiments shown in the drawing.

Fig. 1 is a cross section of the base portion of a railroad rail showing a rail anchor constructed in accordance with my invention applied thereto. 7 0

Fig. 2 is a plan view of the structure in Fi 1.

Fig. 3 is a side view in elevation of the structure shown in Figs. 1 and 2;

Fig. 4 is a view in perspective of the rail anchor shown in the precedingfigure, and

Fig. 5 is a view similar to Fig. 1 showing a modified construction of anchor.

In Figs. 1 to 4 inclusive, I have shown one embodiment of my improved rail anchor. This embodiment consists preferably of a metal bar 10, one end of which is bent upon itself-to provide a jaw 11 adapted to bear against the upper surface of the base flange 12 of a rail, at one side thereof. The said jaw 11 and the portion 13 of the bar 10 define a rail base receiving recess 14, the opening of which is normally less than the thickness of the rail base 12, whereby it is necessary to slightly distort the jaw end of the anchor when the device is applied to its operative position on a rail. The inner portion 15 of'the recess 14 is so formed as to confine the engagement of the jaw portion of the anchor to points within the edge of the rail base and thereby provide a clearance between the jaw portion of the anchor and the vertical edge of'the rail base. In order to provide the jaw portion of the anchor with substantial bearing surfaces, the bottom face 16 of the jaw and the top face 17 of the body are formed with fiat bearing surfaces which grip the upper and lower surfaces of the rail base flange.

The body of the anchor is curved downwardly and upwardly to provide a tie abutting portion 18, which bears against a cross tie at a substantial distance below the rail base. With such construction the anchorfis suitable for use in connection with a. pole or hewed tie, the longitudinal edges of which are ordinarily curved as shown at 20 in Fig. 3 of the drawing. The body portion of the anchor is preferably so curved that the extremity 21 thereof extends upward to engage the edge of the rail base at a point opposite the engagement of the jaw portion of the anchor.

In order-to provide a shoulder to limit the upward movement of the end 21 of they anchor, this end of the anchor is recessed as indicated at 22, so that when the end snaps over the edge of the rail base, the shoulder 23 thereof will bear against the under surface of the rail base.

In applying the anchor to a. rail, the jaw portion of the anchor-is first hooked over one edge of the rail base in a position so that the portion 18 of the anchor will bear against the cross tie. The anchor is then driven in the direction of its length until the end 21 of the bar snaps over the opposite which the recessindmated at 22 in the type" of anchor shownin Fig. 4: is omitted. In this modification, the upstanding end 24 of the anchor snaps over the edge 25 of the rail base into the position shown in Fig. 5. In

other respects the rail anchor shown in Fig. 5 may be, and preferably is, the same in construction as that shown in Figs. 1 to 4 inclusive, and therefore has been given the same ieference character as Fig. 4.

While I have described certain specific embodiments as my preferred construction, it will be obvious that my invention may be modified in structure, without departure from the spirit of my invention. I there fore contemplate all such structural changes as come within the scope of the appended claims.

I claim:

1. A rail anchor comprising means formed with a rail gripping portion adapted to grip the upper and lower surfaces of the base of a rail at one side of the rail, and means extending across the rail base and engaging the other edge of the rail base to hold said gripping portion in position; said last named means being bent downwardly and upwardly with respect to said rail gripping portion, whereby said upwardly bent end portion thereof snaps into engagement with the rail base when the anchor is applied to its operative position.

2. A rail anchor comprising a bar formed at one end with a jaw portion adapted to grip the base of a rail at one side thereof, and formed to confine its engagement to oints within the edge of the rail base, the iiar bein bent downwardly and upwardly to providb a tie abutting portion and to provide an upstanding end portion adapted to engage the edge of the rail base on the side of the rail opposite to that engaged by said jaw portion.

3. A rail anchor comprising a bar formed at one end with a jaw portion adapted to bear with sprin pressure against the upper and lower surfaces of the rail base and formed to provide a clearance adjacent the edge of said rail base, the body and the free end portion of the bar being bent downwardly and upwardly, whereby said free end portion is flexed downwardly during the application of the anchor to its operating position on the rail, so as to snap into engagement with the opposite edge of the rail when the anchor is driven to its applied position.

4. A rail anchor comprising a bar formed at one end with a jaw portion provided with flat bearing surfaces adapted to grip the upper and lower surfaces of the rail base with spring pressure at points within the edges of the rail base, the body and the free end portion of the bar being bent downwardly and upwardly, whereby said free end portion is flexed downwardly during the application of the anchor to a rail so as to snap into engagement with the opposite edge of the rail when said anchor is driven to its applied position.

5. A rail anchor comprising a bar, one end of which is bent upon itself to provide a hook-shaped jaw portion, formed to provide a clearance between the device and the edge of the rail base and adapted to be driven into gripping engagement with the upper and lower surfaces of the rail base, the other end of the bar being bent downwardly and upwardly to provide a tie abutting portion, the upstanding portion of which is so disposed with respect to the jaw portion is, flexed downwardly during the initial application of the anchor to a rail and to snap up into engagement with one edge of the rail base when the anchor is driven home.

6. A rail anchor comprising a bar formed at one end with a jaw portion adapted to grip the base of a rail at one side thereof, the bar being bent downwardly and upwardly to provide a tie abutting portion and to provide an upstanding end portion adapted to engage the edge of the rail base on the side of the rail opposite to that engaged by the jaw portion; the said upstandmg end of the bar being formed with a shoulder ada ted to bear against the under surface of t e rail base adjacent the last mentioned edge of the rail base.

7. A rail anchor comprising a bar formed at one end with a jaw portion adapted to grip the base of a rail at one side thereof, the bar being bent downwardly and upwardly to provide a tie abutting portion and to provide an upstanding end portion adapted to engage the edge of the rail base on the side of the rail opposite to that engaged by said jaw ortion; the said upstanding end of the )31' being formed with an abutment adapted to snap into engagement with the lower corner of the rail base.
