A. G. HATCH- TIE PLATE. AND RAIL FASTENING Mam 5. 1924 Patented July 28, 1925.

UNITED STATES ARTHUR G. HATCH, OF DULUTH, MINNESOTA.

TIE PLATE AND RAIL FASTENING.

Application filed March 25, 1924. Serial No. 701,633.

To all whom it may concern;

Be it known that I, ARTHUR G. HATCH, a citizen of the United States, residing at Duluth, in the count-y of St. Louis and State of Minnesota, have invented certain new and useful Improvements in Tie Plates and Rail Fastenings, of which the following is a specification.

This invention relates to new and improved rail fastening assembly and more particularly to a construction of this character whereby tie plates may be rigidly securedto a tie and a rail rigidly secured to the tie plate by separable securing means. Rails are now generally secured to ties by means of spikes which also secure in place the tie plate. These spikes work loose in the tie in use and not only lose their grip upon the rail but also permit the tie plate to become loose. Furthera fastening of this character is not adapted for use with concrete or similar ties.

It is an object of the present invention to provide rail fastening means particularly adapted for use with concrete or similar cast ties.

It is a further object to provide a construction of this character in which the tie plate is rigidly secured to the tie by means a portion of which is permanently secured to the tie and whereby the tie plate may be insulated from the tie and from the securing means.

It is also an object to provide means for securing the rail to a tie plate the means being adapted to prevent the working loose of the parts in use and to prevent lateral movement of the rail.

It is an additional object to provide a construction of this character which provides rigid connections, which is composed of but few parts and which is adapted for rapid commercial production.

Other and further objects will appear as the description proceeds.

I have illustrated a preferred embodiment of my invention in the accompanying drawings, in which Figure 1 is a plan view of my construction with the rail secured thereto;

Figure 2 is a section taken on line 22 of Figure 1;

Figure 3 is a perspective view of the adjustable washer;

Figure 4 is a X71631? of the clamp plate and Figure 5 is a perspective view of the rail clamping bolt.

The bolts 11 are precast in the concrete ties 12 together with the threaded sleeves 13 into which the bolts are threaded. The upper edge of the sleeve 13 is flush with the upper face of the tie. The sheet of insulating material 14 is placed upon the tie and the tie plate 15 is placed upon the insulating sheet. The stud 16 is threaded into the upper end of the sleeve 13 and passes through the sleeve 17 of insulating material. The upper portion of this sleeve 17 also extends over the upper surface of the plate 15 and the washer 18 bears thereagainst. The nut 19 is screwed on the upper end of the stud 16 and clamps the washer 18 down against its bearings.

The angularly disposed slots 20 are cut into the sides of the tie plates 15, their outer portions being located closer to the rail seating portion of the tie plate than their inner portions. The depressions 21 are formed in the upper face of the tie to receive the heads 22 of the bolts 23. These bolts are provided with squared portions 24 fitting into the angular slots 20 of the tie plates and preventing rotation of the bolts.

The adjustable washer 25 is fitted upon the bolt 23 an edge of the washer engaging the edge of the rail base 26. As shown in Figure 3, the washer 25 is provided with a plurality of openings 27 to receive the bolt 23.- These openings are differently spaced from the edges of the washer so that by using a selected one of these openings and with the washer turned in a selected direction, it will be possible to bring an edge of the washer into contact with the rail throughout a wide range of positions of the rail.

The clamping plate 28 is fitted upon the bolt 23 above thewasher 25 and bears upon the washer and upon the rail base 26. The nut 29 is threaded upon the bolt 23 and retains the bearing member and washer in position.

It will be noted that due to the angularity of the slots 20, the bolts 23 cannot be removed from the slots when the lock washer and rail are in place. It will be necessary first to remove the washer before sliding the bolt from the slot. The present construction provides means whereby the tie plate may be clamped to t tie ind pendently 01 the means securing the rail in place on the tie plate. Therefore the tie plate may be fastened to the tie before shipment from the plant where they are cast while the rail securing means are put inpl-ace at the time of laying the rail in the field. The rail securing bolts may readily be removed and replaced when desired and yet are prevented from accidental removal.

YVhile my invention has been described as applied to a concrete tie, it will be obvious that it may be applied to usual wooden ties, the bolts being placed in bored holes, and I contemplate such changes and modifications as come within the scope of the appended claims.

I claim:

1. A rail fastening assembly comprising a bolt fitted within the tie, a sleeve threaded to the bolt, the upper end of the sleeve being flush with the upper face of the tie, a tie plate bearing on the tie andsleeve, a thread,- ed stud passing through the plate and threaded into the sleeve and a nut carried by the stud to hold the tie plate in place.

2, A rail fastening assembly comprisinga bolt fitted within the'tie, a sleeve threaded to the bolt, the upper end of the sleeve being flush with the upper face of' the tie, a tie plate bearing on the tie and sleeve, a threaded stnd passing through the plate and threaded into the sleeve, a nut carried by the stud to hold the tie plate in place, a sheet of insulation located between the tie plate and the tie and sleeve, and an insulation sleeve between the tie plate and the studand nut.

3. A rail fastening assembly comprising a tie plate, means to secure the tie plateto a tie, slots extending into the sides of the tie p1ate,bolts fitted in the slots and means carriedby the bolts adapted to engage the edge of a rail base, the engagement of said means with the rail preventing removal of the bolts from the slots.

4,. A rail fastening assembly comprising a tie plate, means to s'ecnre the tie plate to a the rail seat than the inner ends of the slots and an adjustable washer carried by the. bolt and engaging the rail, the engagement of said washer with the rail preventing re moval of the bolts from theslots.

6. A rail fastening assembly comprising a tie plate, meansto secure the tie plate to a tie, angularly disposed slots extending into the sides of the tie plate, the openings of the slots being located more closely adjacent the rail seat than the inner ends of the slots, means carried by the bolt and engaging the rail, the engagement of said means with the rail preventing removal .of the bolts from the slots, and a clamp plate, carried by the bolt engaging the rail and retaining the means carried [by the bolt in position.

7. A rail fastening assembly comprising a tie plate, means to secure the tie plate to a tie, angularly disposed slots extending into the sides of the tie plate, the openings of the slots being located more closely adjacent the rail sea-t than the inner ends of the slots, an adjustable washer carried by the bolt and engaging the rail, the engagement of said washer with the rail preventing removal of the bolts from the slots, and a clamp plate carried by the bolt and engaging the rail and adjustable washer to retain the parts in adjusted relation.

Signed at Duluth, Minn, this 17 day of March, 1924. j
