WARREN M. OSBORN, OF CHICAGO, ILLINOIS, ASSIGNOR TO CHICAGO MALLEABLE CASTING-S COMPANY, OF GEHCAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

RAIL-ANGHORING CLIP.

Application filed may 29, 1922, Serial NO. 564,418. Renewed March 10, 1924.

To all whom it may concern: I

Be it known that I, WARREN M. OSBORN, a citizen of the United States, residing at Chicago. in the county of Cook, State of Illinois, having invented certain new and useful Improvements in Rail-Anchoring Clips, do hereby declare that the following is a full, clear, and exact description of the same.

My invention relates to improvements in devices for anchoring railways rails, and its object is to provide an improved clip that locks the rail to the tie-plate with a spring resistance to take-up the vertical or tilting movements of the rails under load and relieve the spikes from the stresses and strains due thereto.

The invention consists in the matters hereinafter described and then pointed out in the claims. a

In the'accompanying drawings, Fig. 1 is a perspective view showing a pair of the clips on an assembled rail and tie-plate; Fig. 2 is a view in cross-section on the line 2-2 of Fig. 1 with the tie added; Fig. 3 is a side view of the clip before being positioned; Fig. 4 is a view partly in side elevation and partly in section showing another form of the clips with the parts in position before the clip is in place, and Fig. 5 is a similar "view of the same parts showing their relation when the clip 1s seated in place.

In the drawings the reference letter A mpresents the head of a rail, B its base, and C the web uniting the head and base.

The clip is made of spring metal, preferably of steel, with a .body 1 substantially square in top plan area and of sufficient thickness to bring its top surface or face above the top edge of the rail-base when the parts are assembled on a tie-plate. The

- body is provided with a spike-hole for the spike 2, and I prefer also to provide it with a spike-heeling lug 3 on its top face and with a heel d on its lower outer end to afford additional thickness to prevent the cli s from tipping or tilting.

ahe body is provided on its lower portion in line with the inner end of its spike-hole with a downwardly projecting lug 5 constructed to extend through the inner end of an elongated spike-opening 6 in the tie-plate 7 and terminating in an inwardly directed wing 8 constructed to extend under and interlock with the inner edge or wall of the spike-opening in the tie-plate. The body is provided above the wing 8 with an integral rigid flange 9 extending its entire length from its upper edge inwardly and upwardly to overlie the rail-base and being bowed or curved to raise its inner end above the base, and terminating in a reversely extended spring-foot 10 formed by coiling the end of the flange.

In the form shown in Figs. 1, 2 and 3 the coil is normally deeper than the distance between the upper face of the rail-base and the lower face of the flange 9 so that when the clip is assembled on the rail the coil makes a driving fit with the base and curls up on itself and is put under tension and compression; in its open position the coil is of larger diameter or section than the space between the rigid flange and rail-base, and when the spike is driven to place in the tie the clip is forced down on the plate and the coil is forced down on the rail-base, and being compressed between the base and rigid flange it is forced to wind up on itself to reduce its section or diameter and so increase its strength to give greater resistance to p.11 vertical and lateral movements of the rai In the form shown in Figs. 4 and 5 the position is longer than the height of the rail web C as shown in Fig. 4, so that when the clip is assembled on the rail and tie-plate the coil makes a driving fit between the rail head A and base B and curls up on itself and is put under compression and tension, and when the spike is driven to place the coil is forced down on the rail base in its compressed or wound up position. In this form the clip has the further capability of acting as a side brace for the rail.

The tie-plate may be provided with a recess 11 in its upper face in rear of its spike hole to receive the body of the clip, as shown in Fig. 5.

In both forms the clip interlocks the rail and tie-plate, and exerts a spring pressure on the rail and takes up all vertical and tilting movements of the rail so that they are not exerted against the. spike and the latter is not pumped or raised from its position in the tie by the rail and is not subjected to any throat-cutting action. For I ea no example, when the rail is tilted side-wise to raise an edge of its base the coil of the clip at that side is compressed or .wound up and so absorbs or takes up the motion of the rail, and similarly when the rail yields vertically under the load of a passing train the coil expands to follow its depression and the rebound or rise of the rail is absorbed and taken up by it. When the load comes on the rail it puts the spring under further compression, and the winding up of the coil increases its strength and gives great resistance to the movements of the rails where their undulations are severe.

The clips may be held in place by the usual drive spikes 2 or by the usual screw spikes 12 as desired, the term spike as used herein being intended to mean any conventional fastener suitable for this purpose.

I claim 1. A rail-anchoring clip comprising a body having a spike-hole, a depending lug at the inner end of the spike-hole having an inwardly directed wing, and a rigid flange on the upper portion of the body above the wing and terminating in a depending coiled spring.

2. A device of the class described comprising a tie-plate having an elongated spike-hole, and a clip havin a spike-hole and an overhanging rigid ange for the rail-base terminating in a coiled spring, and a depending wing on its lower portion underlying the inner edge of the spike-hole in the plate, the spring being constructed to have its coil bear upon the rail-base when the clip is assembled on the plate.

3. A rail-anchoring clip comprising a body having a spike-hole, a depending lug at the inner end of the spike-hole having an inwardly directed wing, a rigid flange on the upper portion of the body above the wing, and a spring coil at the upper end of the flange longer than the height of the web of an associated rail.

4. A device of the class described comprising a tie-plate having an elongated spike-hole and a recess in rear thereof, and a clip having a base constructed to fit said recess and having a spike-hole and an overhanging, rigid flange for the rail-base terminating in a coiled spring, and a depending wing on its lower portion underlying the inner edge of the'spike-hole in the plate, the spring being constructed to have its coil bear upon the rail-base when the clip is assembled on the plate.

In testimony whereof I afiix my signature. WARREN M. OSBORN.
