Abstract
ABSTRACT OF THE DISCLOSURE
A railway fastening, especially adapted for securing a bridge girder or cover plate of the girder to a cross-tie on a bridge, or like supporting structure, is in the form of a resilient clip having a substantially planar body portion with an opening for a bolt which is offset with respect to the resilient end engaging bridge girder. The resilient end in the form of a compression arch engages a girder flange to limit vertical movement and a tie-engaging end includes downwardly and outwardly extending ears for laterally restraining the cross-tie. A shoulder on the resilient end also engages a side of the girder flange to further limit lateral movement. In order to provide greater resilience, the arch can be in the form of two separate finger portions joined at the base with the body portion to form a U, each of the finger portions having a lip adapted to overlie the girder flange. A projecting lug adjacent to the opening for the bolt is provided to facilitate securing a bolt tensioning member, i.e., a nut. The clip thus serves as a large washer to firmly hold the cross-tie as well as the girder when the bolt is inserted through the opening and secured with the nut.

28 Various railway fastenings are described and shown 29 in the prior art bu-t there is a need for a simple reliable railway fastening for securing a girder to a cross-tie on a bridge or 31 other suppor-ting structure.
33 U.S. Patent No. 3,552,649 to Burwell shows a railway fastening 34 for resiliently securing a cross-tie on a bridge in the form Of an elongated resilient clip of rec-tangular crosssection.
36 The clip has a flat end bearing portion for engaging the lOwer 37 face of a tie and an arcua-te bearing portion at its opposi-te 38 end to bear against a bridge girder or cover plate for securin~g RAILS .0-003 273~
1 the tie to the girder. The arcuate portion of -the clip has an
2 elongated slot extending lonyitudinally on the clip to receive
3 a bolt having a diameter substantially less than the
4 length of the slo-t and such as to slidably engage the sides of the slot. This slidable engagement enables the angular position 6 of the clip to be adjusted relative -to the bol-t to thereby adjust 7 the position of the arcuate bearing portion so that the clip 8 can be used with cover plates or girder flanges of substantially 9 different thicknesses.
11 While this clip has performed satisfactorily in most 12 situations,problems arise if the size of the steel tie plate 13 that is on top of a wooden tie is increased, so that the steel 14 tie plate is actually wider than the flange of the steel girder underneath the tie. The top tie pla-te then interferes with drilling 16 a bolt hole to permit the tie to be fastened to the girder flange.
17 It now becomes necessary to move the bolt hole to the side of 18 the girder flange. Consequently, if the bolt is placed outside 19 of the tie plate it will not be next to the girder after passing through the tie and the tie will not be securely fastened. In 21 addition, when the bolt passes through the arcuate portion, care 22 must be -taken to avoid excessive tigh-tening oE -the bolt which 23 can limit the desired resiliency of the clip in securing the 24 girder.
26 U.S. Patent No. 3,659,784 shows a bracket for use with 27 a clamp and screw spike adapted to clamp elevated railroad ties 28 to a support structure. The bracket comprises a U-shaped member 29 with a base portion and vertically extending wing portions.
The base portion is provided with a washer held in an elongated 31 slot. The washer registers with the nut shaped portion of the 33 screw spike to enable the vertically extending wing portions 34 of the bracket to be positioned for securing to the tie. The bracket prevents the screw spike and clamp from disengaging and 36 falling from the tie.

It is thereEore an object of the invention to provide 6 an improved railway fastening which is simple in construction 7 and yet which can secure a bridge girder to a cross-tie and prevent 8 the cross-tie from la-teral and vertical movement on a bridge 9 or similar structure.
11 It is a further object of the invention to provide 12 a railway fastening suitable for use on a bridge supporting structure 13 in which the fastening is secured to a girder and a flat portion 1~ engaging the tie to provide lateral as well as ver-tical restraint.
16 A still further objec-t of the invention is to provide 17 a resilient railway :Eastening device wherein the securing bolt 18 is displaced from the resilient spring portion to permit securing 19 the fastening device to the tie without limiting the resiliency of the spring portion or interfering with a girder cover plate.

1 DESCRIPTION OF THE PREFF.RRF.n EMBODIMFNTS
.. .. .
17 As shown in Figures 1 and 2, the railway .Eastening 18 10 is in the form of a substan-tially planar clip having a curved 19 end. The main flat body portion 12 includes an opening 14 shown rnore clearly ~n Figures 3 and 5, for receiving a bol-t 16 for 21 securing the clip to a cross-tie 18. The hole is offset or spaced 22 from the curved end. The bolt is secured by a bolttensioning 23 member in the form of a nut 20. The curved end engages a girder 24 22 which supports a rail 23 secured on the cross-tie 18.
26 The curved end o:f the clip holding the girder is in 27 the form of a compression arch 24, as shown in Figures 4 and 28 7, which, has two fingerlike portions 26 and 28, shown in Figures 29 3. 5, 6, and 8, joined at the base to the body portion 12 and forming a U-shaped notch 30. Each of the Einger-like portions 31 has a lip 32 which overlies the horizontal girder flange 34.
33 The clip, including the compression arch, is made of 34 a relatively thin sheet of material, such as steel, which is resilient. The arch may be of one piece but preferably, as shown, 36 is formed by two separated f.ingers to provide added resilience.
37 Thus, when -the holt is tightened, the flat por-tion of -the clip 3~ presses against the cross-tie, and the arch resiliently grips R~IT.S 0-003 ~2~3 .~ ~
1 the girder flange. An inner shoulder 35 of the arch also engages 2 the side edge 37 of the f]ange to provide lateral restraint.
4 ~t the other end of the body portion 12 are t~o downwardly and outwardly extending ears or -tabs 36 which, when nut 20 or 6 the bolt 16 is tigh-tened, grip the cross-tie, restraining lateral 7 and vertical movement thereof, as well as longitudinal movement.
9 A projecting luy 38 on the body portion adjacent to the bolt aperture 14 permits the nut 20 to be tightened on the 11 bolt with a single wrench while preventing the bol-t from -turning, 12 and thus, simplify fixing the clip in position. The underside 13 may be indented at the lug as shown at 40.
The offset of the bolt opening 14 from the girder flange 16 3~ and resilient fingers 26, 28 permits use of various sized 17 girders and cover plates without interference from the bolt.
18 In addition, the resi]ient spring action permits some vertical 19 movement while firmly holding the girder in position against the ties without a fixed limit as in -the case where the bolt 21 passes through the resilient end. The bolt, shoulder of the 22 curved resilient end, and ears at the opposite end all cooperate 23 in limiting lateral rnovement of the girder and ties, and the 24 bolt can be tightened fully directly on the washer-like flat portion of the fastening device against the ties to secure the 26 elements together.
28 The use of two spring fingers separated by the notch 29 provides a desired degree of resilience for maximum contact of the shoulder with the side of the flange. The curved lip at 31 the ends of the spring fingers also applies the force more uniformly 32 across the girder flange and avoids the stifness of a sharper 33 edge.
The present invention thus provides an improved simplified 36 railway fastening device which is adaptable to various supporting 37 structures. While the invention has been described in connection 38 with a specific embodiment, it is apparent that many variations 7~
1 may be made in the particular design and configura-tion without 2 departing from the scope of the invention as se-t forth in -the appended claims.

11 While this clip has performed satisfactorily in most 12 situations,problems arise if the size of the steel tie plate 13 that is on top of a wooden tie is increased, so that the steel 14 tie plate is actually wider than the flange of the steel girder underneath the tie. The top tie pla-te then interferes with drilling 16 a bolt hole to permit the tie to be fastened to the girder flange.
17 It now becomes necessary to move the bolt hole to the side of 18 the girder flange. Consequently, if the bolt is placed outside 19 of the tie plate it will not be next to the girder after passing through the tie and the tie will not be securely fastened. In 21 addition, when the bolt passes through the arcuate portion, care 22 must be -taken to avoid excessive tigh-tening oE -the bolt which 23 can limit the desired resiliency of the clip in securing the 24 girder.
26 U.S. Patent No. 3,659,784 shows a bracket for use with 27 a clamp and screw spike adapted to clamp elevated railroad ties 28 to a support structure. The bracket comprises a U-shaped member 29 with a base portion and vertically extending wing portions.
The base portion is provided with a washer held in an elongated 31 slot. The washer registers with the nut shaped portion of the 33 screw spike to enable the vertically extending wing portions 34 of the bracket to be positioned for securing to the tie. The bracket prevents the screw spike and clamp from disengaging and 36 falling from the tie.

.. .. .
17 As shown in Figures 1 and 2, the railway .Eastening 18 10 is in the form of a substan-tially planar clip having a curved 19 end. The main flat body portion 12 includes an opening 14 shown rnore clearly ~n Figures 3 and 5, for receiving a bol-t 16 for 21 securing the clip to a cross-tie 18. The hole is offset or spaced 22 from the curved end. The bolt is secured by a bolttensioning 23 member in the form of a nut 20. The curved end engages a girder 24 22 which supports a rail 23 secured on the cross-tie 18.
26 The curved end o:f the clip holding the girder is in 27 the form of a compression arch 24, as shown in Figures 4 and 28 7, which, has two fingerlike portions 26 and 28, shown in Figures 29 3. 5, 6, and 8, joined at the base to the body portion 12 and forming a U-shaped notch 30. Each of the Einger-like portions 31 has a lip 32 which overlies the horizontal girder flange 34.
33 The clip, including the compression arch, is made of 34 a relatively thin sheet of material, such as steel, which is resilient. The arch may be of one piece but preferably, as shown, 36 is formed by two separated f.ingers to provide added resilience.
37 Thus, when -the holt is tightened, the flat por-tion of -the clip 3~ presses against the cross-tie, and the arch resiliently grips R~IT.S 0-003 ~2~3 .~ ~
1 the girder flange. An inner shoulder 35 of the arch also engages 2 the side edge 37 of the f]ange to provide lateral restraint.
4 ~t the other end of the body portion 12 are t~o downwardly and outwardly extending ears or -tabs 36 which, when nut 20 or 6 the bolt 16 is tigh-tened, grip the cross-tie, restraining lateral 7 and vertical movement thereof, as well as longitudinal movement.
9 A projecting luy 38 on the body portion adjacent to the bolt aperture 14 permits the nut 20 to be tightened on the 11 bolt with a single wrench while preventing the bol-t from -turning, 12 and thus, simplify fixing the clip in position. The underside 13 may be indented at the lug as shown at 40.
The offset of the bolt opening 14 from the girder flange 16 3~ and resilient fingers 26, 28 permits use of various sized 17 girders and cover plates without interference from the bolt.
18 In addition, the resi]ient spring action permits some vertical 19 movement while firmly holding the girder in position against the ties without a fixed limit as in -the case where the bolt 21 passes through the resilient end. The bolt, shoulder of the 22 curved resilient end, and ears at the opposite end all cooperate 23 in limiting lateral rnovement of the girder and ties, and the 24 bolt can be tightened fully directly on the washer-like flat portion of the fastening device against the ties to secure the 26 elements together.
