ANTCREEPER TIE PLATE.

Application filed November 29, 1922.

To all whom t may concern.

Be it known that l, Bntwmirx L. CLEVE- LAND, a citizen of the United States. residing at Chattanooga, in the county of Hamilton and State of Tennessee, have invented certain new and useful lmprovememts in Anticreeper Tic Plate; and l do hereby de-.

clare the following to be a full, clear and exact description of the same, reference being had to the accompanying dra-wings,

forming part of this specification.

This invention relates to devices for holding railroad rails on the usual ties, as well as for preventing the creeping of the rail in a longitudinal direction,

The principal object of the present invention is to provide in a single device means for holding the gage and preventing the creeping of the rail. Ai further object of the present invention is to provide a twopiece anticreeper tie plate. @ther and further objects of the present invention relate more particularly to the various details of construction as pointed out in the claims hereafter.

lt is customary at the present time to use certain tie plates and other devices for holding a railway rail to the cross ties and it is also old to use in combination with these 30 devices for preventing relative lateral movement of the two rails other means for preventing a longitudinal movement or creeping of the rails. ln the device forming the subject matter of the present invention these two means are combined in a single device consisting of two parts which mutually cooperate to prevent creeping, each of the elements at the same time acting as a tie plate.

In the drawings,-

Figure 1 is a plan view of a preferred form of the present invention.

Fig. 2 is'an end view thereof.

Fig. 3 is a section taken on the line 3--3 of Fig. 1.

Fig: 4 is a similar view to Fig. 3 but showing the modication.

The larger of the two members numbered 10 in the drawings may be considered as being the tie plate proper, in its preferred form being a rectangular frame having an oblong centralhole 11 to receive the somewhat smaller cooperating tie plate 12. The larger tie plate 10 is provided with two or more spike receiving openings 14 to receive Serial No. 603,983.

the usual railroad spikes 15 and in accordance with the form of spike used are either rectangular as snown or round or oval if' spikes of that nature are used. At one end of the larger member 10 are located a plurality of jaws 1"? each preferably reinforced by a number of stiflening ribs 1S so that considerable strength without excess weight may be secured.

At the opposite end of the larger member 10 and preferably staggered with relation to .the jaws 17 is a small transverse rib or backing post 20 stiffened like the jaws iT with a. plurality of stiffening ribs 21 and having a relatively steep inclined portion 22 extending from the top of the backing post to the lower surface of the tie plate. The inclined surface 22 may be smooth, toothed, or corrugated, the latter form being preferred and hence illustrated.

The smaller cooperating tie plate is provided with a single jaw 25 with stiffening ribs 26 corresponding in size and shape to the jaws 17 and ribs 18. At the rear end of the jaw 25, however, the smaller tie plate is shortened by a beveled surface 27 adapted to cooperate with the inclined surface 22 and similarly finished, that is, if the surface 2.2 is smooth, it is best to have the surface QT smooth also and in the preferred type since the incline 22 is corrugated the cooperating surface 27 of the smaller tie plate is correspondingly corrugated. Like thelarger tie plate the smaller tie plate 12 is provided with one or more holes 30 similar in size to the holes 14 and for the same purpose. it is to be understood that while l have shown two jaws and two holes lll in the larger member and a single jaw and a` single hole in the smaller member, the invention in-v i 1 Lt 5) cludes obvious changes, for exampleY by providing a number of jaws or holes or both in the smaller member and by having for example a single jaw on the larger member and a plurality of spacing barking posts.

ln the modification shown in Fig. l. for the jaw 25 l substitute a much larger jaw 39v having a` notch 33 to receive the base flange 341 lof the rail and extending up into contact with the inclined surface of the rail 36 to aid the thin web 37 in supporting the rail heads to maintain more effectively the gage. Except for the enlargement of the jaw to form a rail head support, the device shown in Fig. 4 is similar to the simpler construction shown in the otherl three figures. In operation the smaller tie plate 12 is slipped on the rail and the larger plate is then brought into Contact first with the free base flange and then revolved about this as a pivot until the end of the frame swings into contact with the inclined surface 27. The two members as a unit are neXt shifted if necessary into exactposition and the rail lowered against the tie whereupon the larger member 10 is spiked down by means of the members 15 passing through the holes 14. The smaller tie plate 12 is then hammered into position by blows upon the jaw 25, after which this tie plate is spiked into place. It will be noted that vertical p-ressure applied to the head 36 and transmitted through the web 37 and base flange 34 will tend to move the smaller member 12 downwardly and this action by virtue of the contact between the inclined surfaces 22 and 27 will cause the two tie plates to approach each other so as to bite the rail. This will entirely eliminate all possible creeping as during the time the rail is most stressed it is also most. closel)7 held against longitudinal movement. 'By providing the inclined surfaces 22 and 27 with corrugations of very slight depth the downward movement of-the rail under the weight of a train not only draws the two tie plates togather, but leaves them locked after pas-sage of the train.

lli/hat I claim is: s

1 In combination, a tie plate having a rectangular central opening, a plurality of jaws on said plate, a backing post rising from said tie plate opposite and staggered with respect to said jaws and having a corrugated inc-lined surface facing said jaws, a second tie plate having a rail engaging jaw and having the rear end of said jaw corrugated to cooperate with the inclined surface 0f said backing post.

2. An anti-Creeper tie plate consisting of two flat bottomed rail supporting members provided with cooperating inclined fac-es each of said members having a rail flange engaging aw, the jaw of one of said members extending upwardly to engage and support the head of the rail.

3. In combination, a tie plate consisting of a flat plate having a rectangular opening therein, one of the lesser sidesr of said rectangular opening being bounded by a roughened inclined face, a cooperating inner tie plate fitting within said rectangular opening and having a roughened inclined face cooperating with the similar face on the outer tie plate and a rail receiving jaw on eachV of said members. f
