RAILWAY-TRACK STRUCTURE.

SPECIFICATION forming part of Letters Patent No. 784,735, dated March 14, 1905.

Application filed August 1, 1904. Serial No. 219,020.

To all whom it may concern: manufacture of these wear plates or centers.

Be it known that I, GEORGE M. ERVIN, of Said piece A is also cast with the arms or ex: Johnstown, in the county of Cambria and State tensions a a and a a, in which are cored seats of Pennsylvania, have invented a new and usefor the end portions of the connectingrail 5 ful Improvement in Railway-Track Strucmembers A. These pockets correspond gentures, of which the following is a full, clear, erally in section to the section of the lower and exact description, reference being had to portions of the rail members, but are made of the accompanying drawings,which formapart sufiicient size so that after the rail has been of this specification. placed therein there will be left a surrounding IO My invention relates to railway-track strucspace to receive a filling Z) of spelter, Babbitt,

45 tral body of cast metal, preferably steel, in Fig. 9shows the invention appliedtoarightwhich is cored a pocket for a removable wear angled crossing of the three rail type, the plate or center B, which may be of manganese method of construction being the same as that steel, chrome steel, or other specially hard shown in Figs. 7 and 8, except that a removsteel, such as is now generally used in the able center plate is shown. The center may,

however, be formed integrally. In this figure D designates the main running-rails, D the bearing-rails, and I) the guard-rails. Figs. 10, 11, 12, and 13 show the invention applied to a switch-mate. The central cast body F1 is provided with a seat for a renewable plate F and with arms or extensions Gr, in which are formed the seats or pockets for the connecting rail members H.

Fig. 1a shows a tongue-switch of similar type of construction, corresponding parts being lettered the same as in Figs. 10, 11, and 12.

If desired, the cast-metal central body can be made to form a direct support for the heads of the rails. This is shown at it in Figs. 2, 8, 11, and 13. If desired, however, the heads maybe carried on the filling b, as shown in Fig. 5.

It will be noted that in each of the several modifications shown there is employed the feature of a central body provided with pockets to seat the connecting rail members, said pockets being made sufliciently large to receive around the rail members a body of filling material introduced in a fluid state. In the manufacture of this structure the body portion is first cast from patterns. The rail members are then-cut to the desired length and of the proper shape at their inner ends to fit the center piece or plate. They are then placed in the pockets and properly alined and positioned. The molten spelter or other like material is then poured to fill the pockets. This method of construction reduces very largely the amount of shopwork, since the filling will take care of variations in the sections of the rail members and also within certain limits deficiencies in the angle of the intersecting tracks. The amount of fitting required is therefore reduced to a minimum. It is also possible to reduce the number of patterns required, since, as above noted, by means of the filling standard patterns will take care of variations in the rail-sections and in the angle.

A further advantage of the construction is that the parts may be securely held together without depending upon bolts, which, as is well known, constantly tend to work loose.

My invention, as shown, is applicable to both T and girder rail construction and to both steam and street track use and is capable of various embodiments besides the particular ones which I have shown and described and to which I do not limit myself.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a railway-track structure, the combination with a body portion formed with railseating pockets, of rail members seated in said pockets, and a filling in said pockets around the rail members.

2. In a railway-track structure, the combilarger than the rails which they are to seat, rail members seated in said pockets, and a filling material about the pocketed end portions of said rails.

3. In a railway-track structure, the combination with a body portion formed with railseating pockets which are of greater area than the portions of the rails which they are to seat, of rail members seated in said pockets, and a filling surrounding the pocket portions of said rails, said filling being introduced in a fluid or molten state.

4. In a railway-track structure, a body portion formed with seating-pockets for the connecting-rails of the structure, said pockets being of sufficiently larger area than the portions of the rails which they are to seat to leave space for a filling material.

5. In a railway-track structure, a body portion formed with seating-pockets for the connecting-rails of the structure, said pockets corriall y larger.

6. In a railway-track-crossing structure, a body portion carrying the intersecting tracksurfaces, and formed with extensions provided with pockets for receiving the running-rails, said extensions also forming the guard-rail members of the structure.

7. In a railway-track-crossing structure, a body portion carrying the intersecting tracksurfaces, and formed with extensions provided with pockets to receive the running-rails, said extensions also forming the hearing or easing rail member of the structure.

8. In a railway-track-crossing structure, a body portion carrying the intersecting tracksurfaces, and formed with extensions provided with pockets to receive the running-rails, said extensions also forming thebearing and the guard-rail members of the structure.

9. In a railway-track structure, a body portion formed of cast-steel, and provided with pockets to seat connecting-rail members, and also with a pocket to seat a removable wear member.

10. In arailway-track structure, acast body portion having one or more hearing or guard rail members formed integrally therewith, and provided with a pocket to receive a removable intersection piece or plate.

-11. In a railway-track structure,a body portion formed with a pocket to seat a removable intersection or wear member, and with extensions formed with pockets for receiving connecting-rails, said extensions also forming rail members.

12. In a railway-track structure, the combination with a body portion carrying the intersecting tracksurfaces, and formed with pocketed arms or extensions. of rail members seated in the pockets of said arms or extennation with a body portion formed with arms, sions with their inner ends abutting the trackrail-seating pockets formed in said arms and l surfaced portion of said body.

13. In a railway-track structure, the com bination with a body portion carrying tracksurfaces, and formed with arms or extensions provided with rail-seats, of rail members in said seats, a filling material surrounding the seated portions of the rail members, and means for anchoring said members.

M. In a railway-track structure, the combination with a cast-metal body portion formed with a plurality of rail-seating pockets, of rail members seated in said pockets in a filling of softer metal.

15. A body portion for use in the manufacture of railway-track structures, comprising a casting formed with a plurality of arms or extensions, each of which is recessed to seat the end portions of one or more rail members, the rail-seating recesses being of considerably'larger area than the rail members 20 to be seated therein.

16. A body portion for use in the manufacture of railway-track structures, comprising a casting formed with a plurality of arms or extensions, each of which is recessed to seat the end portion of one or more rail members, the rail-seating recesses being of considerably larger area than the rail members to be seated therein, and said arms or extensions themselves forming rail members.

17. In a railway-track structure,a body portion formed with a rail-seating recess of larger area than the rail, a rail seated in said recess, and a filling in said recess about the seated portion of the rail and applied thereto in a fluid state after the rail is seated.

In testimony whereof I have affixed my signature in presence of two witnesses.

GEO. M. ERVIN.
