Description

HANS O. KEFERSTEIN, OF NEW ORLEANS, LOUISIANA.
RAILROAD-TRACK.
To all whom it may concern:
Be it known that I, HANS O. KEFERSTEIN, a subject of the Emperor of Germany, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented certain new and useful Improvements in Railroad-Tracks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to railroad tracks; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed.
In the drawings, Figure 1 is a longitudinal section through a portion of a railroad track constructed according to this invention and applied to a railway track. Fig. 2 is a plan view of the same. Fig. 3 is a cross-section taken on the line a;--r in Fig. 1. Figs. 4 and 5 are longitudinal sections through the slabs showing two modifications.
A are slabs formed of plastic material such. as concrete or cement, or they may be formed of any kind of clay such as used for bricks or tiles, and may be baked or fired like bricks. These slabs are articulated or jointed so as to form a continuous foundation, and the slabs are provided with tongues b and grooves c which fit together and which are arranged in a plane parallel with the top surfaces of the slabs. Each joint may have a single tongue and. groove, or it may have a plurality of tongues and grooves as shown at the right hand in Fig. 1.
D are upwardly projecting flanges on the ends of the slabs, but these flanges may be dispensed with if desired.
Specification of Letters Patent.
Application filed November 12, 1908.
from sliding vertically out of relative Patented July 6, 1909.
Serial No. 462,310.
In order to form curves certain of the slabs A are wedge-shaped or trapezoidal in form, and they are articulated in a similar manner to the rectangular slabs A.
E are cross-ties arranged on the slabs between the flanges D at suitable intervals, and retained in position endwise by the said flanges.
F are rails which rest on the ties, and which are secured to them in any approved manner.
In the modification shown in Fig. 4, the sides of the slabs are made to form tongues b and they are inserted in grooves 0 formed by molding projections or lugs g on the slabs in the form of jaws.
In the modification shown in Fig. 5, the slabs are provided with grooves h, or other surface roughening, to prevent men or animals from slipping on them when the slabs are used for paving streets.
WVhat I claim is:
A railroad track comprising a series ol ce ment slabs having interlocking tongues and grooves at their joints which prevent them os1- tion, cross-ties resting on the said s abs, means for preventing the said cross-ties from sliding longitudinally, and rails extending crosswise of the said ties and the joints of the slabs.
In testimony whereof I have afliXed my signature in the presence of two witnesses.
HANS O. KEFERSTEIN.
