` RAIL-JOINT.

Specification of Letters Patent.

Patented June 9, 1914.

Application led Au gust 10, 19-11. Serial No. 643,295.

To all whom/it may concern Be it known that I, GEORGE E. PELLIssrEE, a citizen of the United States, and a resident of Jersey City, county of Hudson, and State of New Jersey, have inventedcertain new and useful Improvements in Rail.- Joints,as set fort-h in the following specilication.

This invention relates to rail joints.

An object of the invention is to join abutting rail-ends in a railway track in such a manner as to provide resistancev against practically all strains tending to break down the joint and impair the tread line ot' the rail. i

A further object of the invention is to provide for joining abutting rails with convenience and despatch and at the same time to provide and maintain a continuous and unbroken tread from one rail to the joined rail and eiiicient bonding for electrical purposes.

More specifically an object of the inven-v tion rvis to provide for the mechanical reinforcement of the abutting rails at the joint by the attachment of spanning plates to the rail feet while at the same time providing a molecular union/between certain selected parts of the abutting rail-ends.

More specifically this invention is an im provement over the invention described and claimed in my United States liet-ters Patent lilo. 997,697 granted July 11, 1911.

'Ilie above and further objects of the in' vention will be apparent from the following claims which should be read in connection with the following specication, which. specilication is directe-d to illustrative embodiments oi the invention shown in the accompanying drawings, which 'form a part of this application in which like characters designate coiresponding parts and in whichf* Figure l is a longitudinal section through the joint in staggered planes as indicated by line I-I in Fig'. 2; Fig. 2 is a cross-section through the joint along line II-Il of I? ig. 1'; and Figs. 3, 4, 5 and G are each cross sections similar to Fig. 2, but each showing a modied joint.

A and B indicate respectively the abutting rail ends of the railway track, each comprising the head 1, the web 2 and the foot 3.

C .indicates a joint-spanning plate mechanically connected, as by bolts or rivets 4, to span the joint J, directly to the feet or ianges 3 of the abutting rail ends A and B. In Figs. 1, 2, 4 5 and 6 this joint-spanning plate C is shown as a short length of ste-el rail of the same conliguration as the rails A and B, having likewise head, web and foot portions 5, 6 and 7, the same as the corresponding` portions 1, 2 and 3 of the rails A, and B. This spanning-rail, however, is turned upside-down so. that its foot 7 rests against the under face of the feet 3 of the abutting rail-ends A and B.

In forming the ljoint the rail ends A and B are brought closely together inabutting relation,fit being understood that the feet 3 have first been perforated for the reception of the rivets 4L. The spanning-plate C has likewise been provided with perforations to correspond with the perforations in the feet 3. The perforations in the spanning-plate,

however, are all arranged a little nearer to the joint than are the corresponding perforations for the rail-ends. 'Ihe spanningplate C is thenheated so that the expansion of the same causes the rivet holes to register. The 'spanning-plate C is then'riveted or bolted fast to the rail-ends in a manner well known inthe art and as illustrated in the drawucgs.V Selected portions of the crosssection of the abutting rail-ends A and B are then molecularly united. This'may be accomplished by an' electric welding Inachine but the Oxy-acetylene blow-pipe process is preferred. A portionof the metal -is removed from each rail-end at the joint to form a trough-like channel such as the chanlnel 8 at the head of the rail and the channel 9 at the foot of the rail. This channel is then filled in by melting a stick of steel in the blow-pipe flame and causing the same to fuse and weld to the sides of the channel. rIhis illing of metal is designated by 10 for the head-of the rail and by 11 for the foot.

Before illings l0 and 11 have cooled down, `vthey may be compacted by hammering. 'Ihey may be finished oli to have smooth surfaces by'any abrading means such as an emery wheel. It is important that the illing'lO at the head of the rail be inished true with the rail tread as indicated inv Fig. 1 so that a continuous unbroken tread surface 1s provided. Upon the cooling `normally under compression,

of the plate C the rail-ends A and B are forcibly drawn together so that the joint is While the spanning-plate C is normally under tension. In this manner disastrous tension strains are relieved from the joint. The spanningplate is also located in al preferred position to truss the joint and relieve theisame from local strains due to the passage of rolling stock over the joint.

The joint shown in Figs. 1 and 2 is a preferred construction in which both the heads and feet of the rail-ends are molecularly united in addition to the mechanical connection provided by the spanning-plate C. Nevertheless a most eiiective joint is formed by omitting the molecular union for the feet of the abutting rail-ends, so that the joint comprises merely the molecular union 10 for the head of the abutting rail-ends and the mechanical connection of the spanning-plate. Fig. 6.

It is'also contemplated that the resistance against shear at the joint principally supplied by the Web 6 of the structure shown in Figs. 1 and 2 may be supplied by fish-plates, designated by 12 and 13 in Figs. 3 and 4. In Fig. 8. the fish- plates 12 and 13, bolted or riveted to the rails in the usual manner but preferably under tension as described in my aforementioned Patent No. 997,697, supplement the strengthening 'of the joint iven by the spanning-plate C shown in this gur'e as a fiat steel plate 14C.

Fig. 5 illustrates a joint similar to that described in connection With Figs. 1 and 2 except that the molecular union for the feet of the abutting rail-ends is omitted and a molecular union 15 for the abutting rail Webs is provided in addition to the molecular union 10 for the abutting rail-heads.

The structure in Fig. 4 shows head-portions, Web-portions and loot-portions of the abutting rail-ends. molecularly united and the joints reinforced by the spanning-plate v'C and also by the spanning-sh-plates 12' and 13. To complete the joint shown in Fig. 4;, molecular u'nion at the head and footl the head or foot portions alone may be eiii'ected first, With the railends A and B temporarily held in place by temporary fish-plates. The molecular union 15 between the abutting rail-Webs` may then be completed either by electric Welding or by the blow-pipe process after removing the temporary fish-plates.

After the completion of the molecular unions and the cooling down of the railends the spanning-plate C and the spanning-sh- plates 12 and 13 may be attached `portions or at This .modification is shown in' to the rail-ends A and B `according to the previously described process involving a preliminary expansion of the plates byheating or in any suitable manner.

Even When the spanning-plates at the joint are not under tension, their combination in the joint with the molecular union of the rail-ends completes a very eifective strain resisting joint. Likewise the spanning-plate crossing the rail-joint and connected beneath and to the feet of the abutting rail-ends to draw the same into close abutting contact by its normal tension, is itself of importance Within the invention. It is, of course, to be understood that the normal tension of the spanning-plates may be .produced in any efficient manner, the process of heating and cooling being merely illustrative, While eccentric pins and drive pins with staggered holes are both illustrations of other modes of accomplishing the result.
