TIE-PLATE FOR RAILS.

Specification of Letters Patent.

Patented July 18, 1922.

Application filed July 12, 1921, Serial No. 484,144. Renewed April 15, 1922. Serial No. 553,014.

To all whom it may concern:

Be it known that I, EPNEST N. JoHNsoN, a subject of the King of Great Britain, and a resident of the city of Winnipeg, in the Province of Manitoba, Canada, have invented certain new and useful Improvements in Tie-Plates for Rails, of which the following is the specification.

The invention relates to improvements in tie plates for rails particularly as used on railroads and an object of the invention is to provide a tie plate which will effectively support and fasten the rail base to the tie and which will prevent creeping of the rail in either direction.

A further object of the invention is to construct the tie plate so that it will accommodate the varying widths of rail bases and so that it can be adjusted to firmly and positively grip the inserted base of the rail.

A further object is to construct the tie plate in a simple and durable manner and so that no special tools are required for ad justing purposes or for fastening to the tie.

WVith the above more important objects in view the invention consists essentially in the arrangement and construction of parts hereinafter more particularly described and later pointed out in the appended claims, refer ence being had to the accompanying drawing in which Fig. 1 is a plan view of the tie plate as it appears in use.

Fig. 2 is a vertical cross sectional view through the tie plate and rail.

Fig. 3 is a vertical longitudinal sectional View at 3-3 Fig. 1, the rail being removed.

In the drawing like characters of reference indicate corresponding parts in the several figures.

The rail 1 presents the customary head 2, web 8 and base 4 and it is carried by my tie plate 5, the tie plate being mounted on and secured to the customary tie 6. The tie plate comprises a substantially rectangular base or bed plate 7 which sits on the tie beneath the rail and has the underside provided with projecting V-shaped grips 8 which bite into the top face of the tie. The ends of the bed plate which it will be observed extend considerably beyond the base of the rail are provided with spike openings 9 which receive the customary pairs of spikes 10 and 11 which are driven in through the openings to permanently fasten the bed plate to the tie.

The outer end of the tie plate is provided with a stationary jaw 12 which is adapted to receive the adjoining edge of the rail base for the full length of the jaw. The jaw is suitably reinforced by webs 13 cast integral with the base plate and the i aw. The other or inner end of the base plate is formed with an integrally cast upstanding guide or abutment 14: positioned somewhat back from the inner edge of the rail base, the abutment being suitably reinforced by webs 15 similar to those 13.

Here it isto be observed that this guide or abutment presents two tapering faces 16 and 17 at the side towards the rail, the said tapering faces meeting centrally of the base plate at which point they are closest to the rail base. Further, it will be observed that the inner side of the abutment is undercut so that the faces 16 and 17 are inclined and form an acute angle with the base plate. In actual practice the taper is approximately one inch in twelve inches.

Between the abutment or guide and the base of the rail I locate similar right and left wedge blocks 18 and 19 which have their inner sides or those remote from the rail formed complementary to the inner face and top of the abutment and their outer sides or those next the rail formed complementary to the edge of the rail base and slightly overhanging the same. The upper parts of the wedge blocks are oppositely screw threaded to receive the right and left hand screw threaded ends of an adjusting screw 20 extending parallel with the rail and having the central portion thereof formed at 21 to receive a wrench or similar tool.

According to the above arrangement it will be apparent that by turning the screw in one direction or the other one can draw the wedge blocks towards each other or spread them apart and by so doing jam or release the rail base between the wedge blocks and the aw 12.

The base plate is cut away beneath the wedge blocks to provide a clearance space 22 and it is fitted at the sides with extending guide lips 23 and 24:.

When the tie plate is to be used it is spiked to the tie and the wedge blocks are spread apart to permit of the insertion of the rail base. After the rail base has been put in place with the outer side entered in the aw 12 the sectionman tightens up the wedge blocks by operating the screw in a proper direction to draw them together. lVhen the wedge blocks have been tightly drawn in to jam the rail the work is complete.

This tie plat-e not only makes a permanent and solid base for the rail but it also prevents creeping of the rail in either direction. Obviously if the rail attempts to creep in one direction one of the wedge blocks will tighten up and the other release whilst the reverse occurs if the rail attempts to creep in the opposite direction.

What I claim as my invention is 1. A rail fastening, comprising a base plate means thereon engagable with one edge of a rail base an abutment on the base plate spaced from the opposite edge of the rail base, a retaining member removable on the base plate for wedging engagement between said abutment and the adjacent edge of the rail base and means connected to said retaining member for moving same in opposite directions.

2. A rail fastening, comprising a base plate, presenting spaced abutments, one of which is engageable with one edge of a rail base, a pair of wedge blocks mounted for wedging engagement between the opposite edge of the rail base and the remaining abutment and means connected to said blocks operable to move the same toward one another into rail gripping relation or away from one another to release the rail.

3. The combination with a rail and a tie, of a base plate mounted on and spiked to the tie and carrying the base of the rail and provided at one end with an upstanding stationary jaw receiving one edge of the rail base and at the other end with an upstanding abutment spacedfrom the other edge of the rail base the said abutment presenting undercut oppositely tapered faces at the side adjacent the rail and with the faces tapering away from the rail at their outer ends, a pair of wedge blocks inserted between the -tapering faces and the latter edge of the rail base said blocks having the upper parts thereof provided with aligned openings oppositely screw threaded and an adjusting screw having the ends oppositely screw threaded and received within the screw threaded openings of the blocks.

Signed at lVinnipeg, this 17 day of June.
