RAILFASTENING.

Specification of Letters Patent.

Patented Nov. 12, 191.2.

Application fledJanuary 20, 191.2. Seria1,No. 672,351.

To 77 1o/0m .ft may concern Be it known that l, GEORGE H. VRIGHT, :i subject of the King of Great Britain, and a resident of Halifax, .in the Provinceof Xova Scotia and Dominion of Canada, have invented a new and Improved Rail-Fastening, of which the following is a full,clear, and exact description.`

The object ofthe invention is the provision of improved means for holding a rail in position on ties in such a manner as to cause the weight of the rail land 'the weight of a train moving over the rail to cause the fastening to more tightly retain the rail in position.

Another object of the invention is the provision of an improved fastening device formed with bent up portions engaging the web of the rail and the under surface of the ball of the rail and extending to each side of the rail for receiving bolts or other securing means, the bolts being assisted by a plurality of projections or beads eXtending downwardly into the tie, whereby the device cannot move longitudinally of the tie.

In carrying out the objects of the invention the same is preferably formed of a pair of interlocking plates and secured in place b v bolts, spikes, or the like. To the base of the plates are secured or formed integral therewith projections for preventing ,any side movement of the rail. Certain parts of the fastening device are arranged to engage the under side vof the ball of the rail and to extend downwardly and outwardly and engage the turned over or hooked members formed on the ends of 'the base.

'A practical embodiment of the invention is represented in the accompanying draw- .ings forming a part of this specification,

in which similar characters of reference indicatevcorresponding parts in all the views.

Figure 1 is a section through a rail shoW- ing a fastening embodying the invention applied thereto; Fig. 2 is a top plan view of the fastening shown in Fig. '1; Fig. 3 is a plan view of one of the interlocking members of the fastening shown in F ig. 2; and Fig. 4 is a plan view of the second interlocking member shown in Fig. 2.

Referring to the accompany/'ing drawings by numerals, 1 indicates a part of a tie, and 2 and 3 the retaining bolts. It Will be evident that spikes could be substituted for the bolts 2 and 3 withoutdeparting from the spirit of the invention.' The bolts 2 and 3 are arranged to clamp plates 4 and 5 firmly to the tie 1. The bolts are assisted in holding the plates against movement on the tie 1 by projections 6 on plate 4, and projections 7 on plate 5. These projections may be formed integral with the respective plates or rigidly secured thereto,`as found most convenient. Each of the plates 4 and 5 is provided with a hook shaped end 8. The plates 4 and v5 are formed identical and are designed'to interlock so as to occupy the position shown in' Fig. 1, this interlocking being permitted .by the respective slots 9 and 10.

Each' of the plates is formed with a socket portion 11 for accommodating the base of the rail 12, and each is provided With an upstanding member 13 designed to press against the Web of the rail 12. The upstanding member 13 merges into inclined -under surface of the ball or tread of the rail 12 for bracing the rail. TheY bracing membersv14 extend downward and outward until the. outer ends project beneath the hookedv members 8. By this 'arrangement the plates 4 and 5 are thoroughly interlocked so that if one of the bolts should become broken the other bolt would properly hold the fastening plates, and, in fact, if both bolt-s Were removed the projections 6 and 7 would normally preventside movement of the rail.

From an examination of Fig. 1, it will be observed that the base ofthe rail rests upon the interlocking portions of the plates and rests equally upon both plates so that the greater the Weight on the rail, the tighter the fastening is clamped to the tie 1. It will also be noticed that by the arrangement of the members 13and 14 the weight of the train will have a tendency to cause the bearing points 16 and 17, and plates 13 parts and interlocking the same as described,

bracing members 14 which preferably conto move together and clamp the rail more tightly. By forming the plates of duplicate the Weightplaced upon the rail 12 Will tend l plates of identical construct-ion, each plate n plates being formed With a hool shaped end,

jecting retaining member, said retaining 1r ember of one plate extending beneath the hook shaped end of the other plate and said slot of one plate accommodating the part of the other plate not cut out, whereby both of the plates may occupy the same transverse plane, and means engaging each of said plates for clamping the same to a tie.

l. A rail fastening comprising a pair of I l being formed With a hook shaped end, a pressing member designed to extend over the base of the rail and against the Web and f undersurface of the ball of the rail and also provided with an extending retaining member, the extending retaining member of one plate fitting `beneath the turned over end of the other plate, and a securing member passingthrough. each of said plates for locking i the same to a tie. clamping each of said plates to said tie. 2. A rail fastening comprising a pair-0f In testimony whereof I have signed my plates identical in construction, each of said ,l name to this specification in the presence of j two subscribing Witnesses.

interlocking plates formed with means extending therefrom designed to encircle the base of the rail, press against the web of the rail andagainst the under side of the ball of said rail7 a stops extending from each of said plates into a supporting tie for preventing a lateral movement of said rail, and means for a slot extendinglfrom one side to a point i near the center of the plate, a bent up por- |I GEORGE HENRY XVRIGHT tion arranged to engage and press against Witnesses: the Web of a rail and the under side of the `LLOYD W. FENELLY, ball of the rail, and an interlocking prol H. S. HILL.
