tion 18 having depending longitudinal leg portions 19 and 19 formed at the marginal edges thereof. The web portion 18 of the key member 11 has formed on its under surface one or more ways 2O which are inclined in its longitudinal direction, the number of such ways depending upon the number of protuberances l? formed on the yoke with which they are adapted to engage. The inclined ways 20, as shown on the drawings, are formed by deforming the web portion 18 between dies or other suitable means well known to the art of metal working. `The leg portions 19 and 19 are shown in Figs. 1

' to 6, inclusive, to be of unequal depth; the

portion 19 being of sufficient depth to extend below the bottom of the yoke member. Said leg portions are spaced apart a distance slightly greater than the thickness of the yoke member and when the anti-Creeper device is'in operative engagement with the rail base they constitute rigid retaining members which engage the sides of the yoke to prevent lateral relative movement. between the latter; and the key. The leg portion 19 constitutes a tie abutting member of substantial size. A closed end slot 21 is formed in the web portion 18 of the key member' at a point somewhatbeyond the transverse centil) ter line and extends along the key member but terminates at a point short of the end thereof for the reception of the yoke member 10. Y

Preparatory to applying our device to the rail base, the key 11 is assembled onfthe yoke in the position shown in Fig. 1 in the manner set forth in co-pending application for Letters Patent, Serial No. 122,533 filed July 15, 1926. The hook end 14 of the yoke is deformed as at 14, to increase the thickness thereof at that point so as to prevent the removal of the key from the yoke` at that end. The yoke is mounted on the rail base in the manner previously described, to its position shown in Fig. 2, andv is moved longitudinally of the' rail bringing the key into contact with the tie 9, as shown in Fig. 4. In this initial position of the device, it will be seen by referring to Fig.v 2 that the .pro-

tuberances 17 are disposed atthe top of the inclined ways 2O and the key is in its lowermost horizontal position with respect to the plane of the bottom of the rail and in this position provides' a clearance indicated by the numeral 22, between the latter and the upper surface of the key member. In consequence of such clearance, the device is adaptable to fit railshaving different base flange thickness and widths. The extending end of the key is conveniently placed so that it may be struck by a hammer or other implement suitableY for the purpose of driving the key transversely of the rail and longitudinally of the yoke.

"gAsthe keyzis Ydriven transversely of the rail, the abutment face 16 of the yoke bears solidly against the edge of the rail base and prevents the movement of the yoke transversely of the rail. As the key moves longitudinally on the yoke, it is positively guided by the depending leg portions 19 and 19, and the inclined ways V20 engaging the protuberances 17 cause the key to be raised in right lines upwardly so that. the upper surface of same is maintained parallel with respect to the bottom surface of the rail base. T he key is forced into contact with the latter and causes the device to firmly grip the rail. .lt will be seen that the key member is of considerableV length, compared with the length of the under rail portion 12, and when our device effectively engages `the rail, the key extends almost entirely across the bottom of the rail and imparts thereto an upward bearing pressure which is uniformly distributed and secures a strong gripping act-ion on the rail and allows the full length of the lkey to bear against the tie and provides a substantial bearing surface to coact with the tie to effectively check any further creeping tendency of the rail.

By referring to Fig. 5 it will be noted that the legs 19 and 19 extend beyond the end of the web portion 18Ly This extension is sufficient so that when the anchor is in its effective position, as shown in Fig. 3, ,the ends of the legs are preferably-flush or eX- tend beyond the contiguous edge of the rail flange. This extension serves thepurpose of a gage and indicates to the trackman that the key member 11 has been driven to its effective position with respect to the yoke" and the rail.

Referring to Fig. 7 we show a key member having the depending legs 19 and 19 of equal. length. lVith a key of this type, either of the legs constitutes a tie abutting member. Thus our device may be effectively applied to the rail at either side thereof andateither side of t-he tie.

From the foregoing description it will be seen that We have devised an improved anticreeper, which is rigid in construction, is easily applied to the rail base and efficiently grips same to check the creeping tendency of the rail. The yoke member formed of a continuous bar and bent or forged to shape provides greater' bearing surface in contact with the top of the rail base, and eliminates waste in manufacture. The key member, by the increased depth of a depending leg affords greater bearing surface in Contact with the side face of a tie in directions Aboth -ltnigitudinally and vertically of the same,

Cil

and yoke. Furthermore, the key member is extended beyond the rail base and is. accessible to the track operator so that it is conveniently driven without the use of special tools.

A device constructed in accordance with our invention has many advantages over the so-called one-piece anti-Creeper, for instance, a single piece device becomes ineffectitve when the rail to which it is applied becomes worn or corroded and must be replaced, whereas, a device employing our invention may be rendered just as effective as when originally applied to the rail by merely driving the key member with any suitable implement which may be at hand. Thus a track walker observing a loose anti-creeper embodying our invention may easily place it in an effective condition without replacements or the use of special driving tools.

lVhile we have shown our invention in but two forms 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 we 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 our invention what we claim as new and desire to secure by Letters Patent is:

1. An anti-Creeper comprising a yoke having hooked ends to engage the upper surface of the base flange of a rail; and an under rail portion in spaced relation with respect to the bottom of the rail, one or more protuberances projecting upwardly from said portion, a key having a relatively large bearing surface for engaging the under sui'- face of the rail base, and one or more inclined ways formed on said key adapted to engage said protuberances, said key having one or more depending members extending below said yoke when the anti-Creeper is mounted in its operative position on the rail.

2. An anti-Creeper for rails comprisinga yoke, a key extending longitudinally of said yoke and having a closed end slot to receive the yoke, and members depending from said key for engaging the sides of said yoke, one of said depending members extending below said yoke when in operative position on the rail.
