2 Claims.

This invention relates to` railway tie plates and rail fastening means.

One of the objects of this invention is to provide a railway tie plate which is simple in construction and economical to manufacture, in combination with fastening means for holding the rail on the tie plate independently of spikes which are used for fastening the tie plate to the tie, and in which the fastening means or clips are so constructed and arranged with cooperating devices or elements on the tie plate that they may be readily inserted, removed and tightened, particularly the latter. p Another object of the invention is to provide a tie plate in combination with fastening clips, so constructed and arranged as to avoid or lessen stresses which would have a tendency to shear the clips and fracture the tie plate, and which will be arranged in such a manner that the resiliency of the clip will absorb or dampen the rail wave and thus reduce the tendency to damage the parts as mentioned and reduce the tendency of the spikes to loosen.

Another object of the invention is to provide a 2'5 fastening clip in combination with a tie plate so arranged as to prevent or reduce the tendency of rail creeping.

Another object of the invention is to provide a filler strip of novel construction, whereby such a strip may be inserted to accommodate the tie plate to a rail of lesser width than that for which it was principally intended and whereby the strip may be held permanently in place by rail fastening means.

Other objects of the invention are inherent in the device and may be apparent from the following detail description, taken in connection with the accompanying drawing.

Fig. 1 is a plan view, with the ball of the rail removed, better to display the novel features of this invention;

Fig. 2 is a vertical section on line 2 2, Fig. 1;

Fig. 3 is a vertical section showing a modification of the invention; and

Fig. 4 is a perspective View of a filler strip shown in section on Fig. 3.

In the combination shown in the drawing a rail l is of the usual form, having a base 2 with upper surfaces 3 inclining upwardly from the edge of the rail to a web 4. It is understood, of course, that the web 4 supports the ball of the rail, which for convenience in illustration is not shown in the drawing.

A tie plate 5 provides a seat for the rail l. It

has upwardly extending lugs 6 positioned on each (Cl. 23S-349) side of the base of the rail with orifices 'i therethrough to accommodate rail clips which presently Will be described. The base of the tie plate 5 extends outwardly beyond the lugs and, on its upper surface, has detent members to serve as 5 abutments or detents for fastening clips. As specifically shown in the drawing, these detent members comprise corrugations or grooves 8 spaced from each other and running longitudinally. The outer part of the plates 5 have holes lO e to accommodate spikes for fastening the plate to a tie, not shown in the drawing. f

Resilient fastening clips lil, mentioned above, project through the orifices 'i respectively and engage the inclined upper surface 3 of the rail 15 base at a point beyond the edge of the rail, as best shown in Fig. 2. This arrangement provides a resilient section on the clip between the inner edge of the lug 6 and the point of lcontact with the rail for the purposes which will be described later in detail.

The clips l are secured in position by downwardly extending portions Il on their outer ends which may engage in any of the adjacent grooves or corrugations v 525 Ordinarily the tie plate as described will be constructed in such a manner that the lugs ii are accurately spaced to fit a particular weight of rail; but the modification shown in Figs. 3 and 4 illustrates means for accommodating the plate to a 30 rail with a base of lesser width. A filler strip l2 is employed, the strip being inserted, as shown in Fig, 3, between the inner face of a lug and the outer face of the rail; the strip l2 being provided, as best shown in Fig. 4, with a notch E3 to accommodate the fastening clip and whereby shoulders I4 are formed by the notch i3 in cooperation with the clip will prevent displacement of the filler strip.

The tie plate 5 is of such construction that it 40 may be economically manufactured. It may be rolled in bars in a steel mill and the individual plates may be cut or sheared from the finished bar. It is understood, of course, the corrugations 8 as well as the lugs 6 may be rolled in the 45 bar. The orifices i may be punched readily from the rolled stock, and of course, the spike holes 9 may be punched out. 'I'he spike holes 9 may be either round or square as desired; ordinarily they will be square if drive spikes are intended, for 50 fastening the plate to the tie, and they will be round if a screw spike is to be used.

The fastening clips lil are made preferably of steel and thus will have a substantial resiliency. Because of this resiliency and the particular ar- 55 rangement whereby the inner end of the strip contacts the rail base a considerable distance beyond the inner edge of the lug 6, a resilient connection between the rail and the plate is obtained. The arrangement permits a clip to be driven inwardly until the end is deiiected substantially, asV

shown in the left clip Fig. 2. Thus no nicety of adjustment is necessary. In addition, since the point of contact with the rail is substantially beyond the inner edge of the lug there is no danger of shearing the fastening clip at the inner edge of the lug.

Furthermore, the arrangement providing a resilient connection between the tie plate and the rail is responsible for the absorption of violentv shocks, particularly those due to rail wave, and thereby avoids danger of fracture to the lugs on the tie plate and lessens the most severe stresses on the spikes. In addition it permits the use of a cambered plate or the use of a compressible filler, such as wood, between the base of the rail and the seat on the tie plate. Since the clips constantly bear upon the rail with considerable pressure, the tendency of the rail to creep is lessened. Y Y

It is pointed out that the construction and arrangement of the fastening member is such that it may be readilyY tightened. A track-walker can quickly and effectively tighten the fastening simply by giving the outer end of the fastening clip I0 a slight knock with a sledge.

The advantages of the invention should be apparent'now from the foregoingv description. Various changes may be made in the details of construction, within the scope of the appended claims, without departing from the spirit of the invention, and parts of the invention may be used to advantage without the whole.

f We claim;

1. As an article of manufacture a railway rail tie plate approximately one half inch in thickness and twice as wide as the base of the rail with which it is to be used, the base of the plate Vbeing a continuous'plane surface, a pair of lugs upstanding from the top of the plate and dividing the plate into a rail seat, said lugs being slotted,

Ythe top of each slot being in a horizontal plane,

and two extensions outwardly of the lugs, -each extension approximately half as wide as the rail seat, the upper surface of the extensions being parallel with the bottom of the plate and provided with a series of grooves parallel with the upstanding lugs, each extension being provided with spike holes, the rail seat between the lugs being thicker near one lug than the other lug and sloping uniformly from the thicker part to the thinner part to cause the railway rail to tip and twice as wide as the base of the rail withV which it is to be used, the bottom of the plate being a continuous plane surface, lugs upstanding from the top of the plate and dividing the plate into a rail seat and two extensions outwardly of the lugs, said lugs being slotted, the top ofV each slot being in a horizontal plane, each of the extensions being approximately half as wide as the rail seat, the upper surface of the extensions y being parallel with the bottom of the plate and provided with a series of grooves parallel Ywith the upstanding lugs, each extension being provided with one or more spike holes, the rail seat between the lugs being thicker near one lug than the other lug and sloping uniformly from theA thicker part to thethinner part to cause the rail to tip towards one side, in combination with a resilient L-shaped lockingkey, the long arm of the key to be passed through the slot in a lug and rest upon the sloping upper surface of a rail base and positioned initially horizontally, and

the shorter right angular arm of the key engaging an outer groove in the upper surface of an extension, and a ller piece of a thickness suflicient to ll any space left between the edge of the rail base and one ofl the upstanding lugs the ller piece having a notch in its upper edge through which the locking key is to be inserted.
