LOIl'IS-BIiESSING, OF JACKSON. MICHIGAN.

RAIL-JOINT.-

oaesa i 1913.

To all who/1t '12 may concern. 4

Be it known that l, Loris BLESSING, a citizen of the United States of America, residing at Jackson. in the county of Jackson and State of Michigan. have invented cer tain new and useful Improvements in Rail- Joints, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to a rail joint which provides a continuous riding surface for a car Wheel and at the same time permits a certain flexibility of movement in the'rail ends corresponding to the bending of the bodies of the rails under load so that there are no hard spots produced in the track while at the same time the rail ends are kept from being battered.

The invention consists in the matters hereinafter set forth and more particularly pointed out in the appended claims.

In the drawings, Figure l is a view in perspective of a rail joint that embodies features of the invention; Fig. 2 is a view in transverse section taken on or about line II-II of Fig. 1 and Fig. 3 is a view in section taken on or Fig. 1.

As herein shown in preferred form, the end portions 1 of rails of stock form are secured in abutting and alined position in the usual manner. An inner fish plate '2 that has a base flange 3 that conforms to and rests on the upper face of the inner base flanges 4 of the rails is provided with a pair of inner longitudinal ribs 5 that bear against the web 6 of the rail under the influence of a pair of outer clamping bolts 7 and inner clamping bolts 8. The plate is of such depth that the underface of the tread or ball of the rail does not normally contact therewith. The outer bolts 7 pass through apertures that correond vertically in size thereto while the inner bolts-pass loosely throughlarger apertures. An outer plate 9 has an inner marginal flange 1O fitting in the angle of the web about line IIIIII of and outer base flange of each rail and a cor- .responding upper inner rib l1 tha" bears against the web of the rail .at an interval below the tread portionor ba'll thereon. An upright web portion 12 of the outer plate extends upwardly to a short distance below the horizontal plane of the crown of the rail tread. The bolts 7 and 8 pass through both plates and the rail Webs. YVhen in use and Specification of Letters Patent.

This application filed September 10,

under load the inner end portions of the rails can spring down suflicientlv to allow the load to bear ,npon the outer coupling plate, the clearance between the inner end portions of the rail and the upper margin of the inner fish plate permitting it.

Obviously, changes in the details of construction may be made without departing from the spirit of my invention and I do not care to limit myself to any particular form or arrangement of parts.

\Vhat I claim as my invention is 1. A rail joint comprising the combination with a pair of alined track rails with their ends in abutment, of an inner fish plate that bears on the base flange of the rail on one side thereof, the upper margin of the I fish plate being at an interval below the under face of the rail tread, an outer plate have ing an inner marginal flange that bears against the web and base flange of each rail in the angles thereof and provided with an upwardly extending fiange having a tread face at a slight distance below the crown of the rail tread, outer bolts extending through the plates and rail, web and holding the plates against the faces of the web, and inner bolts securing the plates together and extending through the rail webs near the end thereof, the engagement of the inner bolts and webs permitting vertical play of the rails without affecting the bolts.

2. A rail joint comprising the combination of a pair of alined abutting track rails with an inner plate resting on the inner base flanges of the rails and bearing against the contiguous web faces thereof, there being an interval below the lower faces of the rail tread portions and the upper face of the plate, an outer plate that bears against the base flanges of the rail and the adjacent web face thereof and clears the lower faces of the tread portions of the rail,-a portion of the outer plate extending upwardly in contact with the side of" the rail tread portion, of each rail, bolts securing the end portions of the plates to the rail web and closely engaging the latter and bolts clamping through both plates and the inner web portions of the rails and loosely engaging the latter to per-' mit free vertical movement of the rails Without aifecting' the bolts.

A rail joint comprising the combination of a pair of alined abutting track rails with an inner fish plate having a base flange that rests on the base flanges of the adjzv through the end portions of both plates and 15 cent rails, the upper face of the plate being closely through the rail Web, and a pair of at an interval below the overlying portion inner bolts that pass through both plates and of the ball of each rail, an outer face plate loosely through the Web portions of the rails 5 that bears'along its inner lower margin on near the ends thereof, whereby the end. porthe base flanges of the rail, longitudinal ribs tions of the rails are free to move vertically 23 on the outer plate that bear against the adwithout affecting said inner bolts. jacent faces of the rail Webs, the upper lon- In testimony whereof I affix my signature gituclinal rib being it in ikntlelrvzg belpw thle in presence of two witnesses.
