KARL TRNKA, OF SOFIA, BULGARIA.
CONSTRUCTION OF RAILWAY-LINES.
Application filed. October 24, 1911.
To all whom it may concern:
Be it known that I, KARL TRNKA, a subject of the King of Bulgaria, residing at Uliza Aprilofi' 25, Sofia, Bulgaria, have invented certain new and useful Improvements in Constructions of Railway-Lines, of which the following is a specification.
My invention relates generally to railway track constructions and has more especial reference to a construction in which the rail sections and the joints between abutting rail sections are supported by elastic blocks ar ranged upon iron or steel cross-sleepers.
The primary object of the'invention is to improve the laying of rails to insure their firmness by employing special means whereby the rail sections and rail joints are attached to the iron cross-sleepers.
The invention is illustratively exemplified in the accompanying drawings, wherein- Figure l is a transverse section of a rail supported and fixed according to my invention. Fig. 2 a plan and Fig. 3 an elevation of 'Fig. 1. Fig. 4: is respectively an elevation and a section of the rail-fixing bolt. Fig. 5 is an elevation on a reduced scale of the shoe which is fixed tothe sleeper. Fig. 6 is an elevation showing the rail as seated at the rail-joint; Fig. 7 is a plan of Fig. 6; Fig. 8 is a transverse sect-ion through the line E F in Fig. 6, and Fig. 9 a transverse section through the line G H in Fig. 6.
As will be seen from the drawings the rail 1 is fixed to a supporting block 3 seated on the iron cross-sleeper 2 and fastened to the latter in such a manner that it can be removed and another block substituted with the greatest ease. food is the material preferably employed for the supporting block but any other material, having similar flexible properties may be used.
For the purpose of enabling the supporting block to be exchanged as easily as possible an iron shoe 4 is riveted on to the crosssleeper. The side surfaces of the block are sloped so as to form a wedge and the said block is driven into the shoe from the side and fixed therein by means of the bolts 5.
The bearing-surface 6 of the supporting block may have a slope to insure the inclination of the rail when as in the present case parallel ground plates 7 of equal thickness are employed. Holes 9 5 are provided in Specification of Letters Patent.
Patented Feb. 3, 1914.
Serial No. 656,398.
the supporting block to receive the rail-fixing and shoe-fixing bolts 9 and 5.
The slope of the supporting block the form of the bearing-surfaces and the arrangement of the holes for the rail-fixing and shoe-fixing bolts are such that the constructional details can be produced by machinery in one course of working operations. In the case of supporting blocks which are intended for sleepers situated in curves, where a widening of the track is necessary the holes 9 are placed away'from the longitudinal axis of the supporting-block to the extent of the requisite widening.
By special marking of the previously prepared supporting-blocks for different trackwidenings all supporting blocks that are used can be standardized and be kept in stock.
In the form of the invention illustrated in the drawing the devices for fixing the rail to the supporting block consist of through screw-bolts 9 having flattened, circular heads 10. In order to prevent the turning of the bolts when the nut 11 is tightened the heads 10 are arranged eccentrically to the axes of the said bolts (see Fig. 4). The openings 15 formed on the outwardly bent flanges of the shoe for the passage of the bolts 5 are in the form of slots or key-grooves so that the fixing bolts can adapt themselves to the changes of shape occurring in the supporting-block when the locomotives or trains are running over them.
The laying of the rail-sections at the points of junction is carried out in accordance with similar principles. As will be seen from Figs. 6 to 9 the rails 20, 21, are supported at the point where they join by a single block 22, consisting of slightly yielding material, wood for example. In the form of the invention illustrated in Figs. 6, 7, 8, and 9 the block 22 is inserted or driven between two shoes 25, which are riveted to the iron cross-sleepers 23.
The blocks 22 employed for the rail-joint can be easily produced by machinery owing to their form and subject to suitable standardizing, can likewise be kept in stock.
As will be seen from Figs. 6 and 9 plates 30 are arranged under the feet of the rails on both sides of the rail-joint, and held in place by the fish-plates 81 for the purpose of securing a smoother passage of the wheels from one rail-section to another, whereby any considerable wear of the heads of the rails and of the wheel tires is effectually prevented.
What I claim and desire to secure by Letters Patent of the United States is:
1. A railway track construction embodying therein metallic cross-sleepers, substantially U-shaped iron shoes independent of said sleepers and riveted thereto, elastic supporting blocks confined within said shoes, means for securing said blocks within said shoes, rails supported on said blocks, and means passing into said supporting blocks for securing said rails in position, said lastnained means including a bolt having a head embedded in the supporting block.
2. A railway track construct-ion embodying therein metallic cross-sleepers, substantially U-shaped iron shoes independent of said cross sleepers, rivets securing said shoes to said sleepers, transversely bored elastic supporting blocks of substantial wedge shape confined within said sleepers, means passing through the bores in said supporting blocks for retaining the same in position within the sleeper, rails supported 011 said blocks, and bolts having heads embedded in the supporting-blocks for securing said rails in position on said blocks.
3. A railway track construction embodying therein metallic cross-sleepers, substantially U-shaped metallic shoes independent of said sleepers and riveted thereto, wedge shape elastic supporting blocks confined within said sleepers, rails supported on said supporting blocks, and means for securing said rails to said supporting blocks, said last named means including bolts having heads thereon arranged eccentrically to the longi tudinal axis of said bolts.
l. A railway track construction embodying therein metallic cross-sleepers, substantially U-shaped metallic shoes each inclependent of the material of which said crosssleepers are constructed, rivets for securing the bases of said U-shaped metallic shoes to the upper face of said cross-sleepers, supporting blocks of substantial wedge shape confined within said shoes, said blocks having vertical and horizontal bores therein,
bolts passing through said horizontal bores for firmly holding said supporting blocks within said shoes, rails supported on the upper faces of said supporting blocks, and means for rigidly retaining said rails in position, said last named means including bolts passing through the vertical bores in said supporting blocks, each of said bolts having a head at one end thereof arranged eccentrically to the longitudinal axis of said bolt.
In testimony whereof I have affixed my signature in presence of two witnesses.
KARL TRNKA.
