Application and February '11, 1926. Serial No. 88,742.

This invention relates to an improvement in railway track joints and similar structures whereby the joints may be kept lubricated, and binding and corrosion of the various parts thereof prevented.

In the ordinary railway track structure, it is customary to secure the abutting ends of the track rails together by means of angle or fish plates which extend over the joint at each side of the adjoining track rails and are secured between the head'and flange of the rail in such a way as to prevent the endsof the rails moving out of alignment. To hold the ends of the rails in the necessary vertical alignment it is essential that the fish or angle. plates be tightly clamped between the head and flange of the rail, and this necessary tightening of the bolts often brings about such firm contact of the abutting surfaces of the rails and the fish plates as to prevent longitudinal movement of the rail, or of the ends of the rail at the joint, which is necessary to permit expansion and contraction of the rails under changes intem erature- This binding of the railsto the sh plates, preventing longitudinal movement of the rail, is a gravated by the corrosion of the rail and sh plates and the bolts which hold the rails and fish plates together, to such extent that after a short time in service the parts of the joint become corroded together in such a way as to produce a substantially solid connection between the ends of thevarious rails so that for great distances alonga given section of track, the desired expansion and contraction of each individual rail is not realized and the expansion and contraction piles up at one free joint and causes-bendin or warping of the rail, or perhaps brea age. An-

,other disadvantage due to the corrosion of the parts ofthe rail joint is that the tie bolts cannot usually be tightened up after a short time in service because of this corrosion making it necessary in tightening or re airing a track joint, to chisel the existing Its in two' and insert new bolts. impact of the car wheel the steel of the fish plates rubs against the steel rail and considerable wear occurs where two metallic surfaces contact, making frequent tightening of the joints necessary.

It is one of the objects of this invention to maintain a continuous supply of oil between these two surfaces, thereby reducing the wear of the plates and reducing the Under the necessity for tightening upthe joint, while at the same time keepmg the parts of the joint free for relative movement and in. condition to be easily tightened.

Another object of the present invention is to eliminate these various defects and to provide a substantially permanently oiled track joint which will keep the various joints of the track oiled, and permit the desired relative movement of the parts, while still holding the abutting ends of the track rails in their desired alignment.

Another object of the invention is to provide an eflicient means of keeping the track joints lubricated, which means can be manufactured and installed in each track joint at 'a relatively low cost.

Another object of the invention is to provide a substantially self-oiling track joint in which the passage of the wheels over the joint will cause the extrusion of a certain amount of oil from the joint packing over the metal parts of the joint, thereby preventing corrosion.

Another object of the invention is to rovide a lubricating packing or pad w -'ch can be manufactured at a low cost and installed in the track joints with relatively little labor over that now required to make the track joint.

Another object of the invention is to provide a means for keeping the boltsof the track joints lubricated and to prevent corrosion ther f so as to permit tightenin of the bolts 11 desired even after a period of use and exposure to the elements.

Various other objects and advantages of the invention will appear as the descr1ption thereof proceeds.

Referring now to the drawin s, which show several possible forms of em odiment of the invention:

Attempts have been made heretofore to lubricate track joints to permit relative longitudinal movement of the parts thereof and to reduce corrosion, by squirting 011 upon the track joint from cars or other equipment moving on the track rails or by hand, and by providing the rubbing faces of the fish plates against the rail with grooves, throu h which oil can seep into the inside of t e joint. So far as I am aware, however, no

portion of the attempt has heretofore been .made to prov1de a substantially permanently-oiled and packed track joint.

According to my invention the space. be-

tween the fish plates asd' the webs of the rails' is provided with an oil-impregnated packing of fibrous, wick-like, granular or other material, which will retain the oil for a comsaratively long periodof time, and which,

ue to the relative movement of the parts by the passage of the car wheels thereover,

will exude oil into the various crevices and Tie bolts 6 extend through the web of the rail connecting the fish plates on the oppo-- site sides of the joint.

According to this embodiment of my invention, the spaces which normally intervene between the fish plates and the web are filled with oil-impregnated pads 7 which may be com osed of felt, cotton waste, journal-box stu g material or any other fibrous or granular oil-retaining means. These pads are preferably formed to the approximate shape of the space between the fish plates and the web of the rail, as indicated In Fig. 2, and-are provided with holes 8 through which the tie bolts 6 may extend and with end-closing plates 9 which close the ends of the s aces between the fish plates and the web 0 the rails to prevent the leakage of the lubricant from the joint. These end closin plates 9 may be of wood, metal, rubber, ba elite, or any other material suitable toretain the oil in the joint. The pads are preferably of a compressible nature, so as to permit them to be compressed and take more accurately the shape of the opening between the fish plates and the rail, when the fish plates are tightened on each side of the joint. These pads are preferably installed on the track when the track is lald, and the oil in the pads 7 may be renewed at intervals by curing oil over the joint or in troducing lnto the space occupied by the pads in any other suitable way. The tie bolts 6 in this construction are substantially always surrounded with oil, which prevents corrosion, especially of the thread portions and permits the bolt to be tightened or loosened, as desired. In order to protect the end of the bolt and secure lubrication of the threads thereof, the nut 10 for tightening is preferably closed at the end and a suitable liquid or viscous lubricant 11 is inserted in the closed end of the nut, so that upon tightening of the nut the lubricant is forced out along the threads of the bolt to lubricate the threads. A lock washer 10 prevents accidental loosening of the bolt.

It will be understood that the packing or pads 7 may be inserted in the joints in a dr condition and then impregnated with the Oll by pouring or forcing oil into the packing, or the pads may be impregnated with oil before the are installed In the joint.

Fig. 4 s ows a plan view of substantially the type of joint indicated in Fig. 1, certain parts of the rails and flanges being broken away, for the sake of clearness. In this embodiment of theinvention, the ends of the spaces between the fish plates 3 and the rails 1 and 2, are closed by the means of an angle plate 12, Fig. 5, which provides the plug 13 projecting into the openin at the ends of the fish plates and an ang e member 14 which is adapted to lie along the outer side of the fish plate and is provided with a hole 15 for the passage of one of the tie bolts 6, which tie bolt holds the fish plates to the rail, and also the end-closure of the end of the fish plate. The closure 12 may be provided with a valve opening 16 extending through the end of the plate, providing a spring-pressed ball 17 which normally prevents the entrance of liquid into the opening between the fish plates and the rail, or the escape of liquid therefrom. A cap 18 with a bayonet lock joint normally covers the opening 16. To introduce lubricant into the joint, the cap 18 may be removed and'a nozzle or a force pump installed on the projecting end of valve opening 16 and oil forced into the joint and pads 7 under pressure.

To lubricate a jointwhere no end plates are used a suitable wedge-shaped perforated plug may be temporarily pushed into one end of the space between the fish plates and the rail and oil forced through the perforation until the joint is properly lubricated.

The lug may then be withdrawn and move to the next joint.

The tie' upon whi h the ends of the track railsrest prevents or retards the escape of oil from the s ace between the ends of the track rails, an if desired a metal plate or chair may be provided for the ends of the rails to rest upon and to partially seal this crevice.- v t Fig. 6 shows a modification of the invention in which the space between the rail 1 and the fish plate 3 is packed with oil-impregnated cotton waste or journal-box stuffmg material 7 which may be formless, but which, when the fish plate .is tightened against the rail 1,- will take the form of and substantially 'fill the space between the fish plate and the web of the rail. It will be understood that this type of packing, as

well as the form of pad referred to in other portions of the specification, may be installed in the joints of existing trackways,

. either by the removal of the fish plates and the insertion of the formed pads therein, or by stufiin the oil-impregnated formless packing 7* 0 Fig. 6 into the space at each end of the fish plates without loosening of the fish plates and then closing the s ace at the ends of the fish plates by suitablb closing means, such as late 12, Fig. 5, to prevent the escape of 011 from the joint.

Fig. 7 shows an embodiment of a formed oil-impregnated pad 7", which comprises an outer or covering layer of suitable flexible fabric 19 closing an oil-impre ated inner packin material 20 and provi ing holes 21 throng which the tie bolts 6 may extend. This type of lubricating pad may be of rectangular or ot er easily manufactured shape, but is of such a nature that it will take the shape of the space between the fish platesB and the web of 'the rails when tightened up, as illustrated at the right of Fig. 8. The left side of Fig. 8 shows the fish plate 3 with the pad 7 between the plate and the rail before the fish plate has been tightened up into engagement with the rail. In this embodiment of the invention, the

. holes 21 throu h the pad may be lined with a metallic eye et 22 through which the tie bolts pass and which is perforated; as indicated, to permit the passage of oil through the eyelets to the sides of the bolts, to keep the bolts /lubricated.

Fig. 10 shows'an end View of the fish plates 3 which are provided with closure plates 23, secured to the ends of the fish plates by screws 24, extending into the tapped holes in the ends of the fish plates. This type of end closure is particularly suit ed to installation on track oints on existing trackage where the lubricant packing may be stuffed into the joint at each end of the fish plates and the holes for screws 24 drilled and tapped and the closure plates of oil from the jointsl 23 attached thereto, to prevent the escape The invention is a plicable to any t pe of track structure and to third rails, an in addition to the lubricating and anti-corrosion ,function of the packing, it deadens the sound of the cars passing over the track joints. The packing is referably used at every joint of the track, ut its use at specified intervals or on isolated joints is very beneficial in reducing rail breakages. While the invention has been described and illustrated by means ofspecific embodiments thereof, it'will be understood that it is my intention to broadly claim the use of a permanently or semi-permanently, lubricated track joint for railway tracks, and that many modifications and changes may be resorted to within the spirit of the invention without departing from the scope of the appended claims.
