ANTICREEIPING DEVICE FGR EAILYVAY RAILS.

Application filed J'uIy 21, 1921.

To all whom it may concern:

Be it known that I, EMANUEL /Voonines, a citizen of the United States, residing at Verona, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Anticreeping Devices for Railway Rails, of which the following is a -Full, clear, and exact description.

My invention relates to anti-creeping devices for railway rails.

It has heretofore been proposed to construct two-piece anti-creepers comprising a flange-receiving member adapted to extend under a rail in abuttii'ig relationship to a tie and designed to receive a locking key. Such constructions have, however, usually had one flange-receiving loop shaped to accurately engage the flange whereby the flange-receiving member has been held closely against the base of the rail. This has necessitated a special abutment in order to prevent rolling the ties.

By this invention there is provided a flange-receiving member so shaped that it will drop away from the rail base and provide an effective bearing surface against a tie, the cooperating key insuring a positive biting action and consequent holding of the anti-creeper.

Further objects will be apparent upon reading of the following description taken in connection with the accompanying drawings, in which:

Figure 1 shown a section of rail with one of the devices of my invention applied, the device being shown partly in section;

Figure 2 is a view similar to Figure 1, showmg a modified device;

Figure 3 is a plan view of the device shown in Figure 2;

Figure 4 is a partial plan showing a moditied form of key;

Figure 5 is a view similar to Figure 4 showing a further modified key;

Figure 6 is a view similar to Figure 4:, showing a further modified key; and

Figure 7 is a view similar to Figure 4: showing a still further modified key.

Referring to the drawings, the rail 1 having the usual flange 2, is provided with a flange-receiving member 3, having a short loop l closely engaging the edge of the flange 2 of the rail. This member 3 passes underneath the rail flangeand is provided Serial No. 486,488.

at 5 with a larger loop which engages the top only of the flange 2 at 6. The loop is provided with a transverse opening 7 to receive a tapered key 8. The opening 7 is so proportioned with regard to the edge of the rail flange and the size of the key 8 that when the key is driven into the opening one side of the key engages the edge of the rail flange at 9 and the other side of the key 23 engages the material of the member 3 at 10.

By reason of the construction shown, the member 3 is positively locked to the rail flange by the tremendous pressure produced upon the driving in of the gradually tapered key 8. By this means the member 3 is positively locked to the rail flange and when placed in position against the side of a tie acts to positively hold the rail against longi. tudinal movement. The loop l does not provide an accurate flange-engaging opening, so that after the flange-receiving member is applied, it may drop downwardly away from the rail, thereby forming a tie abutment which engages the tie far enough from the top to prevent rolling the same. When the key is driven into position, the binding action of the loop at is increased, and the loop 5 is moved to such a position that it engage the top only of the base flange as described.

The device of Figure 2 is quite similar to that shown in Figure 1, the main distinction being that a portion 11. of the member 3 underneath the flange is rolled or oherwise flattened out so asto increase the bearing surface of the member 3 against the tie. While the device of Figure l is satisfactory, it is in some instances advisable to increase the bearing surface against the tie, and the device of Figure 2 fulfills that requirement. As shown in Figure 3, the downwardly err tending portion 11 is produced by rolling or otherwise displacing the material of the member 8, thus making the portion 11 some what thinner in cross section than the other portions of the member 3.

Figure 4- shows a modified form of key 12. The key shown in Figure 4: may be applied to the member 3 in the form shown in Figure 1 or in Figure 2. This key is placed in position the same as the key 8 of Figure 1, but instead of having a flat surface bearing against the edge of the flange the key 12 is provided with a special biting edge 13 which localizes the locking pressure and friction between the member 3 and the rail flange. It will be noted that the biting surface on the key is on the upper edge oi the key as viewedv in Figure l.

Figure shows "further modified Ltorm wherein the key ll is provided with a plu rality oi biting edge and one being on each corner ol? the key in engagement with the flange.

The form shown in Figure the preferred form or key and has the advantage o't preventing the movement of the rail with respect to the member 3 in either direction. T his advantage results from the fact that the locking pressure is localized at both corners of the side of the key in engagement with l the flange and thereby substantially increases the locking action between the member 3 and the rail.

Figure 6 shows a further modification of key 1'7. This key has a biting surface 18 similar the edge 13 or the key 12 shown in Figure 4 but on the opposite corner of the :tace of the key.

Figure 5 in many respects may be considered as a combination of the key shown in Figures at and 6.

Figure 7 shows a still further modification of key 19. In this case a biting surface is provided along the center of the face of the key in contact with the edge of the flange.

' Many other modifications of the key will occur to those skilled in the art and I am not to be limited to the forms shown and described, as many detail changes may be made in the device without departing from the spirit of my invention.

1 claim:

1. An anti-creeper for rails, comprising a member passing under the rail and having loops engaging the flange on the top at both edges, said loops being shaped to permit said member to drop downwardly into inclined position, and a tapered key passing through said member in engagement with the edge of the rail flange and holding said member in inclined position.

2. An anti-creeper for rails, comprising a member passing under the rail and engaging the flange on the top at both edges, and a tapered key passing through said member, one edge of said key engaging the edge of the rail flange and the other edge engaging said member, said key being eii'ective for rocking said member around one edge of the base flange.

3. An anti-creeper for rails, comprising a member having a loop at one end closely engaging one flange of the rail and a loop at the other end loosely receiving the other edge of the flange and engaging the top only of the flange, and a key passing through the large loop and engaging one edge of the rail flange.

at. An anti-creeper for rails, comprising a member having a loop at one end closely engaging one flange of the rail, and a loop at the other end loosely receiving the other flange and engaging the top only of the J'iange, and a key having a biting edge engaging one edge oi the rail flange and the other edge engaging said member at the large loop.

5. An anti-creeping device for rails, comprising a member passing underneaththe rail, said member having a loop closelyfitting one edge of the rail flange, and a relatively wide portion underneath the rail, a large loop engaging the top only of the rail flange, and a tapered key having a plurality of biting edges engaging the edge of the rail, said key passing through the large loop of said member.

6. In an anti-creeper for rails, a member passing under the rail base and having loops engaging the rail base flange on the top at both edges, and a tapered key passing through said member and engaging the edge of the rail flange, said key having a plurality of biting edges.

In testimony whereof I have hereunto set my hand.
