Abstract
Abstract:
A rail clip for securing for example a crane rail to a girder, comprises a first part to be securely attached, e.g.
by welding or bolting, to the planar surface of the girder adjacent the rail, and a second part to be fixed to the first part independently of attachment of the first part to the girder. The second part has a lateral face for abutment with a lateral face of the rail and the parts have laterally facing cooperating surfaces by which forces applied by the rail to the clip assembly are transmitted via the second part to the first part of the clip assembly. The co-operating surfaces are inclined to the direction of extent of the rail and the second part has an elongate aperture for receiving the fixing means. The elongate aperture is elongate in the same direction as the co-operating surfaces to permit relative adjustment movement between the parts while maintaining the co-operating surfaces in contact. The first and second parts are oppositely wedge shaped, the first part decreasing in thickness in the direction of approach of the co-operating surfaces to the rail so that lateral forces applied by the rail to the clip assembly produce and are resisted by an increase in the tension in the fixing means.

Figure 10 is an exploded perspective view of parts of the rail clip of Figure 8; and Figure 11 is a plan view from underneath of a part of the assembly of Figure 8.
.
The rail clip shown in Figures 1 to 3 comprises a generally rectangular first part 1 which has a planar lower surface for bearing on the rail support, the part 1 being adapted to be welded to the rail support in an approximate position - relative to the rail by one or more welds extending around i~s periphery. A-generarIy rec~angular second part 2 over-lies the first part 1 and has a lateral face 3 for abutmentwith the lateral face 4 of the rail flange. In this embodi-- ment the part 2 is formed with an extension 5 which overlies the rail flange and may carry a resilient member 6 which bears on the rail, if it is desired that the clip assembly should positively locate the rail against upward movement.
-` If the clip is merely required to prevent undue upward movement, the member 6 is omitted.
The parts 1, 2 are fixed together by a bolt 7 of which the - head 7a is located in a recess 8d in the under side of the part 1 and of which the shank projects through apertures 8b, 9 in the parts 1, 2 respectively. At its lower end, aperture 8b extends into the recess 8d dimensioned to receive the head 7a of the bolt 7. A nut 10 with a washer 11 is engaged on the upper threaded end of the bolt. The aperture 8b in - 30 part 1 is at the end of a slot 8c which communicates with an opening 8a through the ed~e of this part to enable the bolt to be placed in position after part 1 has been welded to the ::

~076081 rail support. The aperture 9 in part 2 is elongate in a direction inclined to the direction of extent of the rail to enable part 2 to be moved relative to part 1 to abut face 3 with face 4 and to thereby accommodate variatians in the positioning of part 1 relative to the rail and to permit repositioning of the rail.
Contacting abutment surfaces of the parts 1 and 2 include opposed laterally facing surfaces 12, 13 which extend parallel to the direction of extent of the aperture 9, are arranged to be abutted in all relative positions of the parts, and are arranged so that laterally directed forces exerted by the rail on the part 2 are communicated via the abutted faces 12, 13 to part 1 and thereby to the rail support. It will be appreciated that the fixing means, e.g. the bolt 7 and ^ 15 nut 10, play no part in directly resisting lateral forces on the clip assembly.
~- Wh~le on~-~air af abutted surfaccs is provided in the embodi-ment illustrated in Figuresl to 3, it will be appreciated that two or more such pairs of surfaces may be provided.
The body 2 is wedge shaped, increasing in thickness in the direction of elongation of the aperture 9 towards the rail, so that, should relative movement occur between the parts 1 and 2, caused by lateral movement of the rail, this movement will cause an increase in the tension in the bolt 7 and ~ 25 therefore increase frictional forces between the two parts -~ 1 and 2, to resist further lateral movement. The part 1 is - oppositely wedge shaped to maintain the upper and lower ~; surfaces of the parts parallel inter alia to avoid bending the bolt.
~-.
The above described clip is intended to be capable of resist-ing laterally directed forces of up to about 30 tons. The parts 1 and 2 may be made of forged or cast steel ànd the member 6, if provided, may be made of rubber or an elasto-meric material.

In a modification shown in Figure 4, the part 1 is desiyned to be secured to the rail support by friction grip bolts. To this end the part 1 is made longer and provided with four apertures 14 in its four corners for receiving the bolts.
This clip is otherwise the same as that shown in Figures 1 to 3.
In another embodiment shown in Figures 5 to 7, the clip is similar to that shown in Figures 1 to 3 and the same reference numerals have been used for like parts. However, in this embodiment the extension 5 of part 2 of the embodiment of Figures 1 to 3 has been omitted and the function of holding down the rail is performed by a third part 15 which may be made of spring steel. Part 15 is held relative to the parts 1 and 2 by the bolt 7. To allow the part 15 to have a variable position relative to the first part 1, part 15 is provided with an aperture 16 for receiving the bolt 7, and aperture 16 is elongate in a direction perpendicular to the rail e~tent. rt will be appreciated that this embodiment can also be modified as shown in Figure 4.
Each of the above described embodiments may be modified to include two or more fixing bolts, the first part 1 being provided with two or more apertures 8b and the second part

In a modification shown in Figure 4, the part 1 is desiyned to be secured to the rail support by friction grip bolts. To this end the part 1 is made longer and provided with four apertures 14 in its four corners for receiving the bolts.
This clip is otherwise the same as that shown in Figures 1 to 3.
In another embodiment shown in Figures 5 to 7, the clip is similar to that shown in Figures 1 to 3 and the same reference numerals have been used for like parts. However, in this embodiment the extension 5 of part 2 of the embodiment of Figures 1 to 3 has been omitted and the function of holding down the rail is performed by a third part 15 which may be made of spring steel.
