RAILWAY TRACK STRUCTURE Filed July 19, 1959 3 Sheets-Sheet 1 0- Jom Patented Dec. 10, 1940 PATENT OFFICE 2,224,731 Y RAILWAY TRACK STRUCTURE Oliver W. Johnson, Bethelem, Pa., assignor to Bethlehem Steel Company, a corporation of Pennsylvania Application July 19, 1939, Serial No. 285,232

I 12 Claims.

My invention relates to railway track structures and particularly to means for fastening the rails to the ties.

One of the objects of my invention is topro- 5 vide a novel clamp which effectively grips the rail and cooperates with a member of theroadbed of a railway track structure to limit the vertical movement of the rail thereon.

Another object of my invention is to provide a tie with a retaining member for a rail fastener which member also comprises a reenforcingmember for the tie.

Another object of my invention is to provide a novel clamp and. tie structure for a rail which can be easily assembled with the rail and also easily removed therefrom and which is ideally adapted for use in temporary track installations in industrial plants, freight yards, ore and quarr pits, and mines.

The novel features of my invention will be more fully understood from the following description and claims taken with the drawings, in which Figure 1 is a plan view illustrating a track structure embodying my invention; I

Fig. 2 is an enlarged plan view'of my novel device;

Fig. 3 is a side elevation in Fig. 2;

Fig. 4 is an end View of the device shown in Fig. 3; v

Fig. 5 is a plan View of the clamp; and

Fig. 6 is a side view of the clamp.

Referring to the drawings, I designates a rail, II a cross tie,- I2 a tie plate, and I3 the rail clamps.

The tie I I comprises a member preferably of H or I beam formation, reenforced at the points which support the rails III by reenforcing members I4 disposed intermediate the flanges I and I6 of the tie and welded thereto. The members I4 shown in the drawings comprise angles having their apices spaced from the web I! of the tie and each having legs I8 and I9 extending outwardly therefrom.

Tie plates I2 are preferably welded to ties II and provide seats for the rails II). Shoulders 20 of the device shown and 2| are provided on the tie plate I2 to prevent movement of the rail lengthwlse of the tie.

The rails I0 are assembled with the ties II by placing the rails on the tie plate seats and then applying the clamps I3 thereto.

Each of the clamps I3, as shown in the drawings, comprises a body portion 22 provided at one end with a hook portion 23 having a rail engag- 55 ing toe portion 24, and at its other end with a sinuous portion 25, having a shoulder 26 to. en- .gage the member I4 and a resilient portion 21 to engage the web I! of the tie II. The body portion 22 of the clamp I3 is bent, so as to be angularly disposed in relation to the hook portion 23 5 and so as to. form curved portion 28. Curved portion 28 and toe portion 24 together form a pair of jaws to grip the rail I0 and the tie II.

Clamp I3' is applied by placing the resilient portion2'I of the clamp between the web of the tie I I 10 and the angle I4 with the hook portion 23 of the clamp against the side of the flange of the tie. The clamp I3 is then moved longitudinally of the tie and the toe portion 24 is brought into engagement with the base flange 29 of the rail II) 15 and portionit of the clamp bears against leg I3 of pedestal angle I4 as shown in chain lines in Figure 2. The clamp I3 is then driven into its operative position by sharp blows ofa hammer or otherinstrument on the hook portion 23 in 20 the direction of the rail. As the clamp I3 is drivento its operative position the portion 30 passes over the apex of the angle I4 and the resilient portion 21 of the-clamp engages the web of the tie II causing deformation of resilient I portion 21 of the clamp. After the portion of the clamp passes theapex of the angle the tendency of the resilient portion 21. of the clamp to return to its normal condition forces the portion 30 into engagement with leg I9 of the 30 angle l4.

Asthe clamp is driven into its operative position as described above, the toe portion 24 of the hook portion I5 and the curved portion 28 exerts a gripping action between the flange 29 of the rail I0 and the flange I5 of the tie I I, respectively, the gripping action increasing as the clamp is driven further toward the rail.

It will thus be understood that I have devised a novel structure which permits the rails to be easily and effectively assembled with the ties and which at the same time will afford a resiliency therebetween.

While I have shown my invention in but one form, it will be obvious to those skilled in the art that it is not so limited, but is susceptible of various other changes and modifications without departing from the spirit thereof and I desire, therefore, that only such limitations shall be placed thereupon as are imposed by the prior art or as are specifically set forth in the appended claims.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

1. In combination with a rail, a tie, and a clamp securing said rail to said tie, said tie comprising a web and flanges, and a reenforcing member in spaced relation to said web intermediate said flanges, and said clamp comprising a hook portion in gripping relation with said tie and said rail, a shoulder portion positioned intermediate said web and said reinforcing member lockingly engaging said reinforcing member and a body portion connecting said hook portion and said shoulder portion.

2. In combination, a rail, 2, tie, and a clamp member fastening said rail to said tie, said tie comprising an upper and a lower flange, a web, and an angle member secured intermediate said flanges in spaced relation to said web and said clamp member comprising a rail engaging portion positioned at one side of the tie and having a portion extending from the rail engaging portion to a position intermediate said web and said angle and lockingly engaging said angle.

3. In combination, a rail, a tie, and a clamp member connecting said rail to said tie, said tie comprising an upper flange and a web extending transversely of the rail, a reenforcing member for said flange and having a portion thereof in spaced relation to said web, said clamp member comprising a hook portion, a rail gripping portion and a portion at one side of the tie and a shouldered under-rail portion connected to the hook portion and lookingly engaging said reenforcing member.
