RAILWAY CONSTRUCTION.

SPECIFICATION forming part of Letters Patent No. 527,891, dated October 23, 1894-.. Application led December 26| 1893.l Serial No. 494,693. (No model.)

.To all whom, it may concern: t

Be it known that I, JOSEPH L. SILsBnE, a

citizen of the United States, residing at Chi-V cago, Cook county, Illinois, have invented certain new and useful Improvements in Rail-` way'Construction, of which the following is a specification.

My invention relates to railway systems for the transportation of freight or passengers in which the construction is such that ,the cars move at a higher rate of speed than the axles from which the movement is derived. This is accomplished by attaching the cars to moving tracks resting upon the peripheries of wheels mounted upon axles, so that as the wheels and axles run upon fixed tracks at a certain speed, the moving rails, and the cars attached thereto will move at substantially double the rate of speed of the axles.

The system of construction to which I refer is shown` in a patent issued to Max E.

Schmidt and myself on the 18th of November,

1890, No. 440,725, to which patent I refer for the purpose of avoiding anydetailed description of the general construction of the apparatus employed in suchlsystem. y

My present invention relates to certain devices adapted for use in connection with the above described or similar systems, and my object is to improve upon and modify in va` rious details the traveling rail, and the parts intimately associated therewith.

Stating my present invention in general terms, I may say that it consists, first, in con- 35 structing a flexible traveling rail in sections interlocking at their ends and attached to the car as to provide for the easy running of the cars carried by such rails, either on straight Y lines oraroundcurves; and second, in pro- 4o viding suitable means for connecting the rails andthe cars.

More particularly my invention consists in the featuresand details of construction, and combinations hereinafter described and claimed. v

In the drawings Figure l is aplan View of my improved form of rail, showing the means of connectingit to a car, and for connecting the sections of which the rail is composed, the cars being shown in dotted outline; Fig. 2, a plan viewand an elevation, showing the means of connecting the ends of thesections `car passes.

of the flexible rail; Fig. 3, a cross section on `line 3 of Fig. 2,1ooking in the direction of the arrow; Fig. 4, a transverse vertical section on line 4 of Fig. l, looking in the direction of the arrow. Figs. 5 and 6 are details illustrating the method of connecting the rail to the car. Fig. 7 is a section on line 7 of Fig. 4, looking in the direction of the arrow;

and Fig. 8, a section on1ine8 of Fig. 7. The last seven figures are all on a scale larger than thatof Fig. 1.

The car bodies, track, axles and other parts of the railway system not hereinafter more particularly described, are made in any de-` sired manner, as, for example, that shown in the patent already referred to, the wheels i of any desired length. One length of section,

Vthe use of which isattended with good results, is such as to enable the rail to extend out beyond eachend of the carand pass some littleways under the opposing end of the adjacent car. This length however is not essential, and may be varied whenever the circumstances of the case shall require it, and to accommodate the curves around which the These rails may be attached to the car in any manner that will permit of their efficient operation, and that will not impair theirflexibility to such an extent as to render them too rigid for operation in the manner hereinafter described. In the drawings I have illustrated, and will here describe one mode of attach ment which I consider efflcient,but do not intend to limit my-` self to that precise mode. Attached to the under side of the car bodies are any desired number of pockets B. I preferably usefour of these pockets,ia`s` shown in Fig. 1, one being fastened near each corner of the car; but

any other number may be used, as desired.`

The preferred form of these pockets is more particularly shown in Figs. 5, 7, and 8. In this form the pocket is provided with flanges and flexbilty. The rails are made in sections h by means whereof it is secured to the car body. The ends of the pocket are slotted,as shown at b', to permit the passage of the rail, and the interior of the pocket B is made of a suitable size to receive the shoe D, and the spring E. This shoe D is shown more particularly in Figs. 6, 7, and 8. It is secured directly to the rail A by means of a bolt D which passes through a hole in the rail of a size to tightly fit the bolt, while the holes in the shoe are preferably made of a greater diameter than the bolt, or elongated, to afford play. The ends and top of the shoe are beveled on their inner sides, as shown at d, to allow the rail to rock in the shoe, affording play.

The spring E may consist of a block of rubber, or other suitable elastic material, or coiled or flat springs may be used if desired. As shown this spring fits in the pocket on top of the shoe.

The joints or connections in the sections may come either between the cars, as shown at the lower side of Fig. 1, or underneath the car bodies, as shown at the upper side of that figure. In the former case the section of the rail A will be fastened to the shoe in a pocket at one end of the car, as the vone marked F, and will slide loosely through the shoe in the pocket at the other end of the car marked F. Where the connection comes under the body of the car the rail will be fastened in the same manner to one of the shoes in a pocket at the end of the car.

To connect the ends of the rails I preferably, though not necessarily, employ the following means: Clips G are fastened to the ends of the rails. When the ends of the rails are laid overlapping, the clip on the end of one section will overlap the other section, and conversely, as shown more particularly in Figs. 2 and 3. The ends of the rail sections are preferably beveled, as shown at a, Fig. 3, to prevent any jar on striking the wheel flange, and thereby facilitate the ease and travel of the rails over the wheels.

The method of putting the parts together will be obvious from the above description, and need not be further elaborated.

I n operation the flexible rails will travel along over the peripheries of the wheels, bending readily on passing curves and running without undue jar or friction. In this way I produce what I consider a highly serviceable and eiiicient flexible, sectional traveling rail, which is adapted to all of the exigencies and emergencies encountered in the operation of railway systems of this class, and while I have described more or less precise forms, it is not my intention to unduly limit myself thereto, but, on the contrary, I contemplate all necessary or desirable changes in form or proportions, and the substitution of equivalent members. Some of these changes have already been suggested in foregoing parts of the specication. Others will readily suggest themselves to those skilled in the art. For example: under some circumstances, where the pockets on either side of the joint between the end of two sections are sufficiently near together to hold the sections of the rail with the requisite firmness, the clip G might be omitted; and other similar changes might be made without departing from the spirit of my invention.

It will be noted that the flexible, traveling .rail herein shown is made of separate sections which are not bolted to each other in any rigid manner, but are provided with suitable means whereby the adjacent sections are interlocked with each other in aloose and sliding manner. rail, that is, a rail made of a plurality of pieces heldV side by side and secured together to give flexibility and strength, but is a rail made up of separate sections which overlap each other sufiiciently to preserve the continuity of the rail under all conditions, and which interlock in such a manner that the horizontal adjustment of the rail is constantly maintained, while allowing a lateral motion sufficient for all purposes. In practice each car generally carries a section of rail which is adapted to interlock with a similar section on the next adjacent car. Another advantage of this rail over the composite rail is that it is not weakened by slots used to connect the members of said composite rail. The rail sections here are of a given length, which length depends on the length of the cars, and the overlap of the rail depends on the radii of the curves around which the cars are expected to pass, since the sharper the curve, the greater the overlap required.
