T0 allwhom it may concern:

Be it known that I, NEIL E. SALsIoH, a citizen of the United States, and residing at Bethlehem, Lehigh County, Pennsylvania, have invented certain new and useful Improvements in Mine Railroad Constructions, of which the following is a specification.

The present invention relates to railroad track constructions and particularly to track constructions employed in coal and other mines. r

In mining operations coal or ore carrying cars are used in large numbers, these cars being usually of comparatively light weight and small capacity. They are generally moved slowly so that the mine track constructions need not be designed and constructed to resist strains such as imposed by traffic upon the ordinary surface railroad tracks carrying rapidly moving and very heavy trains. However,the alignment of mine railway tracks must be frequently changed and also it often happens that the tracks are entirely removed from one portion of drift and relaid in another drift. It is of great importance therefore to employ track construction which may be easily disassembled for the purpose of realignment or relocation.

It is the object of the present invention to provide a track construction so designed as to be quite able to support the weight and strains of traflic of mine or surface type ore or coal carrying cars which may be easily disassembled so that the rails and ties may be carried from one point to another and again quickly assembled in a new alignment. A minimum number of parts are employed, which parts are of rugged construction, and simple in design so that the track may be quickly laid or taken up by unskilled labor.

The invention is susceptible of considerable modification and that form which is illustrated in the accompanying drawings is presented by way of example only.

In the drawings:

Fig. 1 is a transverse section of the'iinproved track construction, showing a cross tie in longitudinal section;

Fig. 2 is a plan view of the same;

Fig. 3 is a side elevation of portion of a track, showing a cross tie in end elevation.

The two T rails of the track are indicated at 10 and the cross tie at A, this body being formed of metal by casting, rolling,

forging, stamping or other operation. The outer longitudinal edges of the tie body 11 are turned downwardly as shown in Figure 3 and comprise flanges 11 which rest upon the floor or ground to hold the main portion of the tie out of contact therewith. A maximum strength as a beam is also ob tained by this design. Secured, preferably by spot welding, to the upper surface of the body 11 of the cross tie are plates 12 the inner and outer ends 13 and 14 respectively of each of which are upturned to constitute holding flanges. Flanges 13 make acute angles with the body or main portions 11 of the plate while flanges 14 are substantially semicylindrical and curve outwardly and upwardly so that their edges are substantially horizontally opposite the bottoms of the rail heads. Preferably these flanges are warped as shown in Figure 2, so that the space enclosed between their inner walls and the rail webs is wedge-shaped. Extending into these wedge-shaped spaces are wooden wedges 15 which may be driven tightly into place to cause the rails to be forced against flanges 13 and securely clamped between the outer and inner flanges.

It will be apparent that a track constructed in this manner may be laid or taken up in a minimum of time without skilled labor and that it is a simple matter to give the track the necessary aligment or curva ture. The construction is sufficiently strong to withstand the strains incident to mine traffic and the advantages to be derived from its use will be quite apparent to one skilled in the art. It will be obvious that the design and arrangen'ient of the parts of the invention may be modified without departing from its spirit and scope.

Having thus described the invention what is claimed as new and desired to be secured by Letters Patent is:

1. A. railway track tie comprising a tie body and rail clips welded to the top at the ends thereof, each clip including an inner portion bent at an acute angle to fit the inner flange of a rail and an outer portion which is curved outwardly, upwardly, and inwardly to afford a wedge-receiving space with respect to a rail.

2. A railway track tie comprising a tie body and rail clips welded to the top at the ends thereof, each clip including an inner portion bent at an acute angle to fit the inner flange of a rail and an outer portion which is warped laterally and which is ing an inner portion bent at an acute angle 10 curved outwardly, upwardly, and inwardly ,to fit the inner'fiange of a rail and an outer to aflord a converging wedge-receiving space portion which is warped laterally and which with respect to a rail. is curved outwardly, upwardly,and inward- 3. A railway track tie comprising a tie 1y to afford a converging wedge-receiving body having a web portion with downwardspace with respect to a rail. 15
