RAIL-ANCHQR.

Specification of Letters Patent.

Patented Apr. 22, 11919..

Application filed July so; me. Serial No. 247,402.

To all whom it may concern Be it known that I, LAURENCE J. BERK- ELEY, a citizen of the-United States, residing at Racine, in the county of Racine and State of Wisconsin, have invented certain new and useful Improvements in Rail-Anchors, of, which the following is a specification.

My invention relates to a rail anchor or anti-creepin device, and particularly to a device of this class adapted to engage with one side or base flange only of the rail with which it is associated.

A. primary object of the invention is to provide an article adapted for the purpose described, which will be small, compact and light in weight and, at the same time, will act efficiently to prevent the creeping of the rail. In devices of this general .type which have heretofore been suggested, the engagement of the device with the rail has required the notching or perforating of a portion of the rail, which is inconvenient, expensive and for other reasons undesirable.

In the preferred embodiment of my invention to be hereinafter described in detail, the fastening element consists of a key of substantial size having a sharp edge, the key being accommodated within a lateral guideway in the body of the anchor and meansbeing provided in the guide-way for causing the distortion or deformation of the key as it is being driven in which causes the sharp edge of the key to bite into the base of the rail. This expedient for fastening the anchor to the rail is superior to any heretofore employed in connection with an anchor of this type. I

The invention will be better understood by reference to the accompanying drawings, wherein a Figure 1 is a fragmentary plan view of a rail and cross tie showing the device in position on the rail.

Fig. 2 is a sectional view on the line 2-2 of Fig. 1.

Fig. 3 is a side elevation of the parts shown in the preceding figures.

Fig. 4 is a perspective view showing the body of the anchor.

Fig. 5 is a plan view of the locking key before being driven between the anchor and rail, and

Fig. 6 is a side view of the key in its deformed condition bearing against. the base of the rail.

Like characters of reference designate like parts in the several figures of the drawings.

The device is shown as applied to one flange of the base 10 of a rail. The body of the anchor consists of a shoe preferably of malleable iron having upper and

lower iaws

11, 12, which outline a tapered recess 13, adapted to accommodate the flange of the rail. The jaws are strengthened by the provision of the marginal ribs or

flanges

14, 15, the latter being extended and joining a depending flange 16, adapted to lie alongside of the tie 17.

The shoe is provided with a recess or keyway 18 arranged transversely of the rail. The key-way is shown as being formed in the lower jaw 12, but, as will be apparent, it might, if desired, be located instead in the upper aw 11. A key or locking member 19 is adapted to be accommodated within the key-way, the key being angular in cross sec tion and preferably of triangular form, as shown. One edge 20 of the key, corresponding to the apex of the triangle, is made relatively sharp and the key is disposed .in the key-way or recess 18 with the sharp edge In order to cause the key to bite into the base flange the key-way is provided with a hump or upward bulge 21 preferably near the inner end thereof. The shoe is placed on the base flange. Preferably it is driven tightly thereon with a hammer or maul. The key 19 is then driven into the key-way 18. When the end of the key reaches the bulge 21 in the bottom of the key-way the cutting edge 20 of the key is forced up into the rail base cutting a groove therein, the key bending around the bulge until it assumes the position shown in Fig. 2. The forward end of the key is preferably beveled as shown at 22 so that the key will be-sure to ride out of the rail base and bend down over the bulge. I When the device has been locked to the rail in this manner it cannot be removed therefrom without drivin out the key. The anchor so attached will withstand a pressure considerably heavier than any normal creeping stress. In case the rail contracts so as to carry the anchor away from the tie this movement does not affect in any way the hold of the device on the rail.

While I have shown and described the in vention in a preferred embodiment it will be apparent that changes in the form and arrangement of the parts of the device might be madeavithout departure from the principle of the invention.

I claim:

1. In an anti-creeping device, the combination of a recessed member adapted to engage the base ,flange of a rail, said member having a key-way arranged transversely of the rail, an angular key adapted to be driven into said key-way, and means in the key-way for deforming the key to force an edge thereof into biting engagement with the rail.

2. An anti-creeper comprising in combination a member providing a pair of jaws adapted to engage the base flange of a rail, one of said jaws having a key-way arranged transversely of the rail, and a key adapted to be driven through said key-way between the jaw and the rail, and means in the keyway for deforming the key to cause the same to bite into the rail.

3. In an anti-creeper, the combination of a member provided with a tapered recess to accommodate the base flange of a rail, and with a second recess which is open throughout a portion of its length to the first mentioned recess, a key adapted to fit into said second recess and provided with a cutting edge to bear against said base flange, and means in said second recess for causing said cutting edge to bite into the rail base as the key is driven through the second named recess.

4. In an anti-creeper, the combination of a member provided with a tapered recess to accommodate the base flange of a rail, and with a second recess which is open throughout a portion of its length to the first mentioned recess, and a key of angular cross section adapted to fit into said second recess; the latter being formed so as to cause said ke sald base flange.

'5. In an anti-creeper, the combination of a member provided with a tapered recess to accommodate the base flange of a rail and with a second recess which is open through out a portion of its length to the first recess, a key adapted to fit into said second recess provided with a cutting edge, and a hump in the bottom of said second recess for forcing the cutting edge of said key into the rail as the key is driven through said recess.

6. In an anti-creeping device, the combination of a member shaped to engage one side of a rail and formed with a key-way transversely arranged with respect to the rail; and a key, having a. cutting edge, adapted to be driven through said key-way with the cutting edge in contact with the rail; said key-way being shaped so that when the key is driven'into position it is bent and the cutting edge thereof forced into the rail.
