MAX MATTHAEI, or cAssEn-wILHELMsHonn GERMANY.
METALLIC-BAIL-SUPPORT oonsrnuo'rron.
Application filed July 31,
To all whom it may concern:
Be it known that I, h/[AXIMATTHAEL a citizen of the German Republic, residing at Cassel-Wilhelmshohe, Germany, have in vented certain new and useful Improvements in MctallieRail-Support Constructions, for which I have filed an application for patent in Germany on the 18th of May, 1922, and of which the following is a specification.
This invention relates to a permanent way with iron longitudinal sleepers and cross sleepers in which the cross sleepers are located in incisions in the lower side of the longitudinal sleepers and connected with the same to form rigid frames. The improved construction according to the invention differs from constructions of known type in that the longitudinal sleepers are cut out up to the web which rests directly upon the web of thecross sleepers and further in that flaps are welded on the edges of the incisions in the flanges of the longitudinal sleepers, said flaps being in contact with the flanges of the cross sleepers and connected with the same by means of screws.
The advantages of this improved construction over the constructions of known type consist in that the part of the web of the longitudinal sleeper which is left in the incision is on its entire surface in close contact with the web of a cross sleeper so that the points of intersection loaded by the rail are doubled and it consists further in that the cross sleepers are tightly embraced by the longitudinal sleepers owing to the close contact mentioned and to the flaps of the longitudinal sleepers fitting tightly on the flanges of the cross sleepers.
An embodiment of the invention is illustrated by way of example on the accompanying drawing in which a permanent way shown in Fig. 1 in plan view.
Fig. 2 is a longitudinal section on larger scale than used in Fig. 1.
Fig. 3 is a cross section through the rail.
Fig. 4; is a cross section through the cross sleeper, and
Fig. 5 is a plan view of Fig. 4, these Figures 3, f, 5 being on a still larger scale than Fig. 2. v
The U-shaped iron longitudinal sleepers b are cut out in accordance with. the shape of the cross section of the U-shaped cross sleepers h, i. The incisions of the longitudeep that only a part m 1924. Serial No. 729,402.
ofthe web remains which is designedto come incontact with the upper surface of the corresponding cross sleeper. Flaps 21, fixed by welding on the edges of the incisions or the flanges of the longitudinal sleepers, bear against the flanges of the cross sleepers and are connected with the same by means of screws 0 with nuts.
It is not necessary that the flanges n are made of separated pieces welded to the cross ties, they may be taken from the material of the longitudinal sleepers.
As at the points of intersection only the flanges of the longitudinal sleepers are cut out, the web of the U-shaped cross section of the longitudinal sleepers being preserved, the rails are continuously supported by the longitudinal sleepers and the frames consisting of the longitudinal sleepers and of the cross sleepers give great solidity to the entire construction. Sagging and the wear resulting therefrom are thus reduced. The solid construction permits of increasing the distance between the cross sleepers wherefrom results economy in material. It is further important that at the points of intersection any weakening by connecting screws is avoided. a
As the joints of the longitudinal sleepers are outside of the sleeper frames the projecting ends of the longitudinal sleepers form bracket supports so that, when a train is rolling over the rails the flanges of the cross sleepers are loaded in the direction oi the screws 0. When cross sleepers with wide flanges are used (Fig. 4:) the cross sleepers have the tendency to lift the web at whereby. the supporting strength of the web is increased.
The vertical pressure at the points of intersection of the sleepers is transferred also to the welded flaps (see Fig. 5) this being a further advantage of the improved construc tion. The easy displacing of the longitudinal sleepers with the rails on the same in the direction of the cross sleepers is another ad vantage of the construction, as the welded on flaps have longitudinal slots for the screws (Fig. 5). It is thuspossible to ac-. curately adjust the rails to the gauge without the necessity of loosening any rail fastenings.
I claim A permanent way with iron frames composed of U-shaped longitudinal and cross sleepers, the cross sleepers being inserted responding flaps of the longitudinal sleeper are in close contact with the flanges of the corresponding cross sleeper, and screws for fixing said flaps on said cross sleepers.
In testimony whereof I afiix my signature in presence of two witnesses.
