Description

Patented Jan. 14, 1930 UNITED sTATss rari-:NT oFFlcE PHILIP L. KOPP, OF BURKSVILLE, ILLINOIS, ASSIGNOR OF ONEI-IALF TO ALOIS Il'.` KOENIGSMARK, OF WATERLOO,`ILLINOIS TRACK CROSSOVER FOR RAILROADS i j Application mea apra 4,

` the same, and including guards or guides for the wheels of the cars passing said crossover in either direction, the rails forming "the3crossover in the present instance having sufiicientbody at the joints to reduce to a minimum the wear at these points by practically eliminating vibration of the rails during the passing of a train thereover.

A furtherobject of my invention is to construct a cros'sover for railroad tracks L that will have the required rigidity at the joints and yet provide for the use of the usual spikes or bolts in securing the rails to ties or a metal plate forming a platform for the crossover, with the ends of the "125 jointed rails constituting my invention shaped to join to the ends of ordinary rails for the continuation of the tracks.

Other objects and advantages of my in vention `will hereinafter appear "in this specification, and what I particularly claim` as new and `desire to protect by Letters Patent is specifically set forth in the ap` pended claims. j M In the drawings, forming a part hereof Figure l" is a plan view of a railway track crossover constructed in accordance with my invention.

Figs. 2 and 3 are sectional views on the `lines 2-2 and 3 3 of Fig. 1, and

.Figa 4 is a transverse sectionalview of `Fig. 1 through the joints ofthe rails on a line with the groove to receive the wheel flanges of the railway cars. j

Referring to the drawings, 5 5 and 6-6 designate the rails forming the crossover',`

1929. Serial No. 352,485.

the rails 5 in the present instance representing those of the main line or track over which a greater amount of traffic passes and are of a slightly different construction at the joint to increase the stability of the crossover structure, as hereinafter explained.

In carrying out my invention the rails 5 and 6 at the points where they cross one anotherare rectangular in cross section, being of a height corresponding with that of the ordinary railroad rail and of a Width to present a wide tread 5a and 6a, respectively, at the upper portion thereof With adjoining guard-rail portions 7 separated by "longitudinal grooves 8 for the usual 60 wheel flanges of railway cars, the grooves of one set of rails bisecting those of the other and the guardrails extended beyond the joints a suitable distance and beveled outwardly at their ends, as shown in Fig. G5 1 of the drawing. A lap-joint is formed between the crossed rails by oppositerecesses in said rails respectively, the recess inthe rail 6 being deeper than `that in the main rail 5 to increase the body of said last men- 70 tioned rail at the joint, as shown in Fig. 4, it being noted that the portion 9 of rail 6 is below the recess in which the longitudinal portion 10 of rail 5 lits and that it rests directly on the support for the 175 crossover," Furthermore, it will be noted that by having the rails rectangular in cross section at the joint or joints and closely it ting the interlocking portions of said rails,

a strong, rigid and durable jointis provided to withstand the traffic passing the crossover in either direction, both rails having a wide bearing on the support to prevent vibration and reduce wear at the joint.

In order toilighten the rails, and more especially for the purpose` of securing the rails to the supportV on the, roadway by means of the usual spikes 18 each rail is cut away centrally between the joints, as at l1, and similarly cut away beyond the oints, as at 12, in each instance leaving a ottom flange 13 corresponding with the usual bottom. flange of the ordinary railroad rail over whichthe head of the spikes project in securing the rails in place, the cutaway portion at the inner side of each rail of the crossover terminating at a suitable distance from the end of the guide portion 7 to provide a solid portion 14 which increases the strength of the end of said guide portion. The end of each rail which projects beyond the guide portion is reduced in width so that it may be joined to the ordinary rails 15 by tie plates 16,

The crossover may be supported on the usual railroad ties (not shown) but in order to increase its stability a metal plate or platform 17 is placed under the same and provided with holes through which the spikes are driven into the ties, or bolts may be used instead of spikes, and although I have shown the crossover for single tracks tlie same arrangement may be carried out for double tracks; furthermore, instead of 4having the tracks or rails 5 and 6 crossing each other at a right angle they may be constructed to cross at any angle desired by changing the formation or angle of the recesses at the interlocking joints.

From the foregoing description it will be readily seen that I provide a construction of crossover for railways in which the rails are shaped to not only provide a strong and rigid ]oint which will withstand heavy traflic but also provides for securing the crossover in place by means of the ordinary j spikes or boltsand for connecting the rails constituting said crossover to ordinary rails for the continuation of the tracks, the increased width of the tread and base portions of the rails of the crossover giving the desired weight or body at the points usually subjected to wear-that is at the joints and ends of the guard portions or guide-rails. The construction of the crossover employing the rails of the particular construction herein shown and described can be easily ylaid after the manner of ordinary rails, and

although I have illustrated the preferred embodiment of my invention it will be understood that changes, such as liereinbefore suggested, may be made without departing from the spirit and scope of the appended claims.

I claim:

1. A crossover comprising solid rails rectangular in cross section where they cross `each other at which point the upper portion of one rail and the lower portion of the other are provided with rectangular recesses for interlocking engagement of the crossed rails to form a close-fitting lap joint, with the upper and lower surfaces of both rails in the same horizontal planes.

2. A crossover com risinr solid rails rectangular in cross section and provided with longitudinal grooves to receive the car-wheel rim-flanges and form guard portions extending upwardly with the vthread portions of said rectangular shaped rails, the rails where they cross each other having rectangular recesses in the upper and lower portions thereof respectively to receive the crossed rails and form a close-fitting lap joint, with the upper and lower surfaces of both rails in the same horizontal planes.

3. A crossover comprising solid rails rectangular in cross section and provided with longitudinal grooves to receive the car-wheel rim-flanges and form guard portions or guide-rails extending upwardly parallel with the thread portions of said rails, the rails where they cross each other having rectangular recesses in the upper and lower portions thereof respectively to receive the crossed rails and form a close-fitting lap joint with the upper and lower surfaces of both rails in the same horizontal planes, said rails being cut away at opposite sides beyond the joints to reduce the weight of the same the spikes to secure the crossover in place.

4. A crossover comprising solid rails rec tangular in cross section and provided with longitudinal grooves to receive the car-wheel rim-flanges and form guard portions or guide-rails extending upwardly parallel with the thread portions and beyond which the main portion of the rail projects and is reduced in width, joints for the crossed rails.

lar n cross section and provided with longi.

tudinal grooves to receive the car-wheel rimflanges and form guard portions or guiderails extending upwardly with the thread portion and beyond which the main portion of the rail projects and is reduced in width, joints for the crossed rails formed by opposite rectangular vrecesses for interlocking engagement of the rails, the opposite sides of the rails forming the crossover being cut away between the joints and beyond said joints with the cutaway portions of the guard portions or guide-rails terminating near the ends of said guide-rails.

6. A crossover comprising rails rectangular in cross section and provided with longitudinal grooves to receive the car-wheel rimflanges and form guard portions or guiderails extending upwardly with the thread portion and beyond which the main portion of the rail projects and is reduced in width,

and provide base flanges for engagement of Alos joints for the Crossed rails formed by opposite rectangular recesses for interlocking engagement of the rails, the opposite sides of the rails forming the crossover being out away between the joints and beyond said joints With the cutaway portions of thegua-rd portions or guide-rails terminating near the ends of said guide-rails; together with a platform on which the crossover rests and to which it is secured.
