' ANTI-RAIL-cnnnrnn.

Specification of Letters Patent. Patented Aug. 22, 191 (i.

- Application filed May 13, 1916. Serial N o. 97,243.

we do hereby declare that the following is' a. full, clear, and exact description thereof. l

Cur invention has for its primary object to provide an anti-creeper attachment for railway rails, wherein a rail tie-plate is arranged to co-act with rail grippingclips to cause said clips to frictionally bite the rail with increasing force, in proportion to the tendency of the rail to creep. Thusa metallic contact between the stationary element andthe movable element is attained to produce a positive `gripping result to hold the rail, in contradistinction to the ordinary method wherein the rail-gripping member is opposed by the standard wood tie.

Another object of our invention to pro vide an anti-rail-creeper which will. act with equal efficiency to prevent creeping of the rail in either direction.

.lt is also within the scope of our invention to provide a simplified form of the antin creeper containing the generic principles set forth, but capable of operating in connection with a rail wherein traffic in one way only is the mechanical problem offered.

It is also an object of our invention to provide an exceedingly simple anti-rail"- creeper embodying a fixed metallic element and a rail-carrying metallic element, which elements operate frictionally, due to the tendency of the rail to creep, without the assistance of' springs or other members to become damaged or broken. l a

With the above and other minor objects in view the invention consists in certain peculiarities of construction and combination of parts hereinafter set forth with reference to the accompanying illustrations and subsequently claimed.l

in the drawings Figure 1 represents an inverted plan view of an anti-rail-creeper embodying the essential elements of our invention; F ig. 2, a longitudinal sectional view through the same, the section being in-v dicated by line 2-2 of Fig. 1; Fig. 3, a crosssection through the rail and its gripping clips, the section being indicated by line 3-3 of Fig. 1, and Fig. 4, a detailed :face view' of one of the rail clips showing the method of locking the clamping nut, which clip is opposed by the thrust-arm of the pad-plate.'

Referring by characters to the drawings, l represents a tie-plate which is secured to the wood tie by spikes 1', the said spikes also serving to clamp the base flange 2 of the rail in place in the usual manner. The tie-plate in this exemplification of our invention is provided with a longitudinally extended thrust-arm 3 and a pull-arm 3,

the pull-arm'being provided with a downturned jaw el.

Secured to the base flange 2 of the rail are a pair of' grippmg'clips 5, 5', each' ofA which is provided with channels (i, into which the edges of' the rail base flange are fittcd. The clips are firmly locked in their positions upon the base flange by a bolt 7, which bolt passes through suitable apertures that are formed in the clips aforesaid. The head 7 of the bolt is fitted in a rectangular seat 8 that is formed in the clip 5', whereby Asaid bolt is held against twisting under the vibratory strain imparted thereto due to trafc over the rail. ,The opposite clip 5 is also provided with a rectangular seat 8 about the bolt aperture for the reception of a boss 9 that forms part of a washer 10, the said bossbcing rectangular in shape so as to prevent rotary movement of the washer. The flanged portion of the, washer which abuts the juxtaposed face of the clip is provided'with a series of companion radially disposed cuts at its periphery, whereby a series of locking tongues l1 are formed, as shown. After the nut 7 of the clan'iping bolt is firmly seated to draw the clips into` the bolt and nut will serve to draw the clips' as firmly as possible to the edges of the rail base flange and in this initial assemblage, as shown, the bolt extends approximately at a right angle to the longitudinal axis of the rail and itffollows that the channels 6 are gripped to the 'edges of the rail in parallel relation thereto. -In this initial assembled position of the parts, the clip 5 will abut the end face of the thrust-arm 3 and the jaw 4 of the pull-arm 3, as shown in F ig. 2, will be in approximate Contact with an upturned jaw 12 of a finger' 13, which finger projects from the clip 5. In this initial position of the parts, should the rail tend to creep in the direction as indicated by the uppermost arrow in Fig. l, the thrust-arm 3 will prevent movement of the clip 5, While the eli p 5 will advance with the creeping rail in the direction of the uppermost arrow. Thus it will be seen that the bolt will take a slightly oblique position, as will also the gripping clips, whereby said gripping clips by their skew will cause an abnorlnal gripping engagement of their channeled surfaces with relation to the rail and thereby lock the rail against creeping. Should the rail tend to creep in the opposite direction, as indicated by the lower arrow, the end of the thrust-arm 3 will travel slightly away from its contact with the clip 5 and the aws 4 and l2 of the pull-arm 3 and finger 18 respectively will be brought into locked engagement, whereby the creeping tendency of the rail will exert a friction grip of the clips in the same manner as that previously described. Thus it will be seen that by the arm elements associated with the tie plate,

vaimetallic Contact is effected between the clips, whereby an abnormal gripping strain 1s' put upon them lrrespective ot the direction of travel of the rail due to its tendency ot' creep. Hence the device will operate efiiciently for single tracks where the traffic is moved in both directions.

It is manifest that for double tracks or in instances where the traffic is in one direction only, a single arm may be employed in connection with a tie-plate to eo-act with a clipmember to obtain the desired results.

It will also be observed that primarily the aiiti-rail-creeper as a whole comprises only four parts, to wit: the tie-plate, two elipplates, and the bolt element,-aml that no springs or mechanism to become loose or jarred is embodied in the structure. In other words, the greater the tendency of' the rail to creep, the greater the friction force will be applied to the clips to prevent such creeping and if any wear takes place this friction force is suiiicient to automatically take up such wear.

We claim:

1. An anti-Creeper for rails comprising a tie-plate having a thrust-arm and a pullarm extending therefrom beyond the body of the tie to which the tie-plate is secured, a pair of channel gripping clips adapted to be fitted to the edges of the rail, a tie-bolt for the gripping clips, means for effecting abutting engagement with one of the clips and the thrust-arm, and means for effecting a pulling engagement between the other clip and said pull-arm, whereby thegaforesaid 'clips are caused to exert an abnormal f'rictional gripping engagement or draw upon the rail flange irrespective of the direction of movement of said rail.

2. An anti-Creeper for rails comprising a tie-plate having a. thrust-arm vand a pullarm extending therefrom beyond the body of the tie to which the tie-plate is secured, a pair of channel gripping clips adapted to be fitted to the. edges of the rai'l, a tie-bolt for the gripping clips, means for effecting abutting engagement with one of the clips and the thrust-arm, and jawsfor interlocking engagement between the pull-arm and other clip. whereby the aforesaid clips are caused to exert an abnormal frictional gripping engagement or draw upon the rail flange irrespective of the direction of movement of said rail.

3. An anti-Creeper for railway rails comprising a tie-plate for, supporting the rails adapted to be secured to a tie, an arm extending from the tie-plate beyond the tie bod y. channeled clips fitted to the base fiange ot the rail, the face of one of which clips is in juxtaposition to the arm whereby it will abut the same when the rail creeps' in one direction, and a clamping bolt connecting the clips crosswise of said rail basel fiange.

ln testimony that we claim the foregoing we. have hereunto set our hands at Racine, in the county of Racine and State of `Wis cousin, in the presence of two witnesses.v
