RAIL FASTENING Filed Feb. 1, 1928 V llmwemior Patented Oct. 15, 1929 UNITED STATES JOHN MORTKA, F BROOKLYN, NEW YORK RAIL FASTENING Application filed February 1, 1928. Serial No. 251,080.

This invention relates to improvements in rail fastenings, particularly to a fastening for removably securing the rails of railroad tracks to metal ties, and it is the principal object of my invention to provide a rail fas-- tening in which adjustable shoes engage the inner rail foot flanges, and cooperate with outer shoes in such manner as to allow a ready exchange of the rails.

Another object of my invention is the provision of an outer rail fastening shoe equipped with a removable cover plate firmly engaging and gripping over the outer rail foot flange, whereby a quick release of the rail is effected by the simple removal of said cover plate.

A further object of my invention is the provision of a rail fastening for rail-road ties of simple and inexpensive construction the rail foot flange engaging members of which are controlled by means of a turn-buckle arrangement.

A still further object of my invention is the provision of a rail fastening means presenting convenient seats for the rails and interlocking rail engaging shoes whereby means are provided to quickly and readily engage and disengage the shoes with and from the rails.

These and other objects and advantages of my invention will become more fully apparent as the description thereof proceeds and will them be specifically defined in the appended claims.

In the accompanying drawings, forming a material partof this disclosure,

Fig. 1 is a side elevation of the preferred form of rail fastening, partly in section on line 99 of Figure 2.

Fig. 2 is a top plan view thereof.

Fig. 3 is a top plan view of a cover plate.

Fig. 4 is a top plan view of the tie, Figure 2, from which the fastening operating means have been omitted.

Fig. 5 is a fragmentary sectional detail view of one end of the tie, Figure 4.

Fig. 6 is a detail view of one of the rail fastening shoes or members.

The figures on the drawings show a tie, preferably a metal tie in the form of a box 41, hollow, and adapted to receive ballast or cement etc. The rails 42 and 43 in this form of my invention rest with their foot flanges on seats 44, 45 transversely arranged on the upper cover flanges of box 41, separated in the middle in the direction of the longitudimil axis of the tie and the seats are secured to these flanges by suitable fastening means passed through the perforations 46 -of the seats .44, 45, which have upstanding side flanges 47, 48. 4

The rail fastening means of this form of my invention consist of shoes 49 entered with thelr lower extended members into the box '41 adapted to grip with their upper heads 50, which are undercut at one end to receive and grlpover 'the inner foot flanges of the rails 42, 43, while grooves 51, 52 guide and'engag'e the upper flanges 53, 54 of the upper part of box 41 in which enlarged spaces 55 are formed allowing the introduction of the shoes 49.

In their rear faces the shoes 49 have openings 56, preferably threaded for the reception of the threaded ends 57 ofa turn-buckle 58 having a central perforation 59 for the reception of the usual pins for operating" the turn buckle (not shown), and recesses 60 in the upper flanges 53, 54 -allow a convenient operation of these pins.

A cover 61 having recessed ends 62, 63 covers the central part of the box 41 whereby the g ggar parts of heads 50 engage in said recesses The outer rail fastening shoes 641have rail foot flange engaging upper heads 65' and are held in place by means of pins 66 passed 5 through opening 67 in the box 41. The inner faces of shoes 64 are formed to receive and support the outer bevelledends 68 of shoes 49,.as indicated at 69.

My device operates as follows:

The rails are placed with their foot flanges on the seats 44, 45 which are of such a width that the flanges 47, 48 snugly and firmly engage the side edges of the rail foot flanges. Now the inner turn-buckle operated and connected shoes 49 are brought into the box 41, through openings 55 and by the proper operation of the turn-buckle arrangement are brought into flrm engagement with the foot flanges which they overlap. The bevel edges 68 of these shoes are then brought into firm engagement with the inner faces of the shafts of shoes 6 L by the proper operation of the turn-buckle arrangement pressing their heads, as they turn about pivot pins 66, firmly into gripping engagement with the outer rail foot flanges. Then the cover 61 is put in place.

It will be clear that a simple release of the engagement of the inner shoes 49 and their heads 50 by the proper manipulation of the turn-buckle arrangement will allow a ready I 7 release of the rails.

It is to be understood that I have shown and described the preferred form of my rail fastening device as examples only of the many ways in which the same may be practically constructed, and that I may make such changes in the general arrangement and in the construction of the minor details of my invention as come within the scope of the appended claims without departure from my invention.

Having thus described my invention what I claim as new and desire to secureby Letters Patent is 1. In a rail fastening of the class described the combination of a box-like tie having upper spaced cover flanges, a cover for said box, seats for the rail feet on said cover flanges, movable inner shoes adapted to be introduced through suitable recesses in said cover flanges into said box-tie, lower extensions on said shoes, outer shoes adapted to grip over the outer rail feet, and a means for pressing the lower extensions of said inner shoes against the outer shoes for pressing the heads into engagement with the outer rail feet. and means for locking the parts in their relative adjusted positions.

2. In a rail. fastening of the class described, the combination of a box-like metal. tie with sets of headed movable shoes, one set engaging the outer and one set engaging the inner. foot of a rail. the outer shoes pivoted intermediate their ends in said tie, and having abutments and supports formed on theirinner faces, the inner shoes each having a lower extension bevelled at the outer end to engage said abutments of said outer shoes and supported thereby, a means for firmly engaging the heads of said shoes with the foot flanges of the railroad rails, and a means for locking the parts in their relative adjusted positions to firmly securethe rails to the tie. v

I Signed at New York,in the county of New York and State of New York this 21st day of January, A. D. 1928. 7
