Description
HERMAN VICTOR BAIINTS, OF AMSTEBDAM, NETHERLANDS.
To all whom t may concern.'
Be it known that I, HERMAN VICTOR BAINTS, a subject of the Queen of the Netherlands, residing at Amsterdam, Province of North Holland, in the Kingdom of the Netherlands, have invented certain new and useful Improvements in Rail-Junctions, of which the following is a specification.
The invention relates to an improvement of the junction of the rail-ends and especially of such junctions in which the one rail-end is provided with a projecting part and the counterparting end of the junctionrail has a corresponding recess; both ends are shaped in such manner that a vertical pressure on one of the rail-ends'by one or more supporting faces at different elevations is transmitted to the junction rail end.
The invention has the following advantages: 'Ihe rails in the passage of traiiic thereover bend at the oints in an elastic line so that they act similarly to a continuous rail; the rails may be laid or taken up in a very short time with a consequent reduction of cost in the construction of a railroad; and the joints require very little supervision, especially in those cases where the lish-plates commonly employed are dispensed with, since the danger of the rails spreading at the joints is reduced, if not eliminated.
Arched supporting faces are known in rail junctions but not with the above mentioned characteristics. By the arched shape of the supporting face as above indicated, the resistance capacity of the overlapping part is highly increased without harming considerably the solidity of the lapping part.
In view of the construction of the improved rail joint the collection of water is excluded from the adjacent faces or surfaces by reason of the fact that there is an overlap or overhang of one part in respect to the other and as a consequence rust deterioration is prevented.
The application of the invention effectively prevents the lateral sliding of the rail ends with regard to each other, which appears especially at curves in consequence of the pressure of the wheel flanges. It is not so dangerous when the fish bolts work loose in a construction according to the present invention as it would be in previous constructions, where it was disastrous, as a lateral sliding of one of the rail ends is entirely prevented by the invention. In ap- BAIL-JUNCTION.
Specification of Letters Patent. Patentedsept, 30, 1919, Application med April 1e, 1919. serial No. 290,577.
plying the invention, the vertical pressure can be transferred on one or more arched supporting planes situated on different heights of therail profile. The accompanying drawings illustrate-a mode of embodying the invention.
Figures 1 and 2 represent a form of car-l rying out the invention, in which the upper supporting face, coinciding with the railhead, is arched while the lower supporting face, being level, is situated at half the height of the railfoot. It may be remarked that also the lower supporting faces may he arched according to the invention.
Figs. 3 and 4L are detail perspective views ofv portions of rails and embodying a slight modification.
Fig. 5 is a transverse vertical section through the structure shown by Fig. 3 and taken in rear of the reinforcement at opposite sides of the rail.
It appears from the drawings, that the rail-ends are constructed in such a manner, that even without fish plates the difference in levels during the using of the rail road is neutralized while a lateral sliding of the rail ends is prevented by a special form of the supporting faces.
Any kind of fish plates may he used at the rail junction according to the invention.
The supporting faces may be put vat different heights of the rail section; both rail ends should remain sufciently strong lest deformation may appear.
The supporting face transmitting the vertical pressure from one rail end to the other is represented in the drawing by a, y
Z) is the corresponding supporting face of the junction rail taking up the pressure, and c is the end face of the rail. The end face of the projecting part of the one rail is indicated with d, while the end surface 0f the corresponding recess in the junction rail is represented by e.
The arch of the curved supporting face is preferably elliptical. In the drawing the vertical section represents an ellipse with the longitudinal aXis passing through the lower part of the head.
The supporting faces of the rails should not exceed a certain length, a desirable length being from 3.5 centimeters to 5 centimeters.
If the end faces make an angle with a vertical plane, which is perpendicular to the greater than 30D:
The invention may be used with the same having a snug fitting coperating construcy tion. o M
2: rail j'int haviiggtlr v'head of one rail cut yertically at a distance from the free end advantage with double headed English rails tvfor'n a square abutting shoulder the full 30 and with grooved rails as it gives in using the' usual rails.`
The Figs. 3, 4 and 5 illustrate the invenf tion applied to rails With reinforced prole, in the joints; Y
What I claim is: ,y l'. A rail joint vhaving the head of one rail cut vertically at a dista-nce from the free end Y to forni a square abutting shoulder the full extent across the head and'i'nftersected bya' Y horizontal yconvex support continuing fully Yto the rail end and of less Width than .the
head, and an adjacent rail having a vstraight head end with a concave recess cut intoand solely under the thread surface of the head .toreceive and fully inclose the` horizontal convex support of the first named rail end with the said straight head endv abutting against the 'said shoulder,l the remaining vv'eb and base flange portions of the rai-l ends Copies of 'thisl patent may be obtainedi for extentacross the head and intersected 'by a 'horizontal convex support continuing fully to the rail yendand of less Width than the head andal'so having the base flange` hori- Zontally undercut and transversely reduced by square side shoulders and a projecting vertical* web, and an adjacent rail yhaving a straightheadzend `With ,a concave recess Cut into and solelynunder the thread surface of thehead al1-d the" Web also cut -a'Way vertii cally and the base lrecessed above ,the lower side to snugly receive the support, projecting Web and undercut, side shouldered portions of the firstv mentioned rail end- Y In testimony whereof I have hereunto set f vERM-AN VICTORBAINTS.
