Patented June 28, 14932'` UNITED STATES PATE NTv` OFFIC i JOHN 1. NORTHEY AND RODNEY v. NORTHEY, OF TORONTO, ONTARIO, CANADA Application IedDecember 13, 1930. kSerial No. 502,171.

This invention relates to devices for securing rails to the ties of a railway track including tie plates and means holding therails in position on the tie plates, and our Object ki is to devise retaining means with which slotted key bolts may satisfactorily be used. We attain our object by means of constructions which may be brieiiy described asifollows A tie plate is formed with ribs between which a rail base may be positioned. A clip is provided which is tted 4against the upper surface of the tie plate and extends over the top of the rail base. This clip is held in place by means of a key bolt extending up through the tie and tie plate and provided with a wedge key engaging the upper surface of the clip. Preferably the clip is formed with two key seats at different distances from its under surface and is slotted so that it may be slid to bring either key seat in alinement with Vthe key. Thus a greater or lesser take-up is provided for any given position of the key. Preferably in either position of the clip shoulders on the clip and tie plate will be engaged to prevent swinging of the clip relative to the bolt.

The invention is hereinafter more specili-v cally described and is illustrated in the Vaci companying drawing in which Fig. 1 is a cross'section of a rail, tie plate and clip;

Fig. 2 a plan view of av single clip and part of a tie plate and rail;

Fig. 3 a section on the line 3--3 in Fig. 2;

Fig. 4 a cross section of part of a rail, tie

plate and a clip, showing a modification of the invention;

Fig. 5 a plan view of a modification of the clip ;y

Fig. 6 a plan view of another modication of the clip; and

Fig. 7 a plan view illustrating the mode of manufacture of the clip shown in Fig. 6.

Referring to the drawing, 1 represents a tie and 2 a tie plate provided with ribs 3 forming a recess for the base 4 of a railway rail.

5 are clips, each having an end 6 adapted to extend over the rail base, as shown, but preferably out of contact therewith, so that the rail may spring upwardly to alimited extent ,withoutimposinga stress on the clip. Each clip engages surface v"I of the tie plateon which it is adapted to slide to and from thev rail. Shoulders Sand 9. are Vadapted to inter-` engagetolimit ythis movement in 'either di rection. s

Each clip is formed with a slot 10. A key bolt 11 'passes' up from the tie, the tie plate.` and the Yslot10.` Through the slot of the key bolt a wedge key 12 is adapted to `be driven and to engage the back of the clip at different places according-to the position o f the clip relativeto the rail. Preferablytheback of theclip is formed with denite keyseats 13 v and 14 positioned at different distances from the under surface of the clip and preferably separatedbya rib 15.'y

'- It isevident from this construction that,

assuming the parts to be in the position shown I in Fig.` 1 and assuming that the wedge key has been driven as far as possible through the slotin the key bolt and there isstill in-j suflicient take up, the wedge key may be re-` la tail-16 engaging the rib 17` on the tie plate.

so Y

The under surface of" this tail is substantially parallel to the surface 7 on which the clip slides. This tail serves to cause a lifting stress applied at the end 6 of the clip to betransmitted to the bolt much more nearly in the line of its axis than is the case in the form of the clip shown inFig. 1.4

The form of clip shown in Figs. l and 2 is such that it is most readily made -as a malleable casting.

In Fig. 5 we show a form ofclip adapted to be made from a rectangular bar of metal 5a.

In this form the slot 10a is open ended, the

end 6n being formed by the double portion of the bar.

In Fig. 6fwe showa form of clip stamped out by a die press. As shown in Fig. 7 such a. clip can be cut Without Waste from a flat strip of metal.V In this form the part b corresponds to the part 5 of Figs. 1 and 2 and the'part 6b to the part 6.

5 What we claim as our invention is:

l. The combination of a tie plate; a clip resting on the tie plate and having an end adapted to extendrover the base of a rail resting on the tie plate; aslotted ke bolt passing p through the tie plate and clip rom below ;a

Wedge. key.; adapted. t0 be @elven thrmlgb the slot 1n the key bolt in engagement with the clip; and interengaging shoulders on theti'e. plate and clip to prevent the latter turning on 15, the tie plate. Y-

2. The combination of `a tie plate; avvclip resting onthe tie` plate and having an'end adapted to extend over the base. of a rail resting. on the tie plate, the said clip being longif tudinally slotted; a slotted'key bolt passing y through the tie plate and the slot in theclipfrom below; and a wedge key adapted tobe driven through the slot in the'l key bolt, the c lip having bearing surfaces for therkey at different distances from its tie plate engaging surface and at different points in 'its length.

3, A construction according to`clai1n2 inV which ythetie plate and clip are provi-ded with shoulders adapted to interengage to prevent tunning of the Clip, on theboltvvhenV the bolt is adjacent either end of theslotvn the clip.

4. A construction according to clai1n25v1n which the tie' plate and clipare provided with shoulders adapted to interengage to prevent turningof the clip on the bolt when the bolt is acent either end of the slot inthe clipand iiiwhich the clip is provided with atailpiece extending over and engagement with an 4 Outer part 0f the teplate Y 5. construction according to claim: 2 in which the clip Vis movable along a. plane at right angles to the axis of the bolt anddeinite key seats are formed on the clip at-di'erent points in its length. c Y
