dDJ'USTABLE TIE-PLATE.

Specification of Letters Patent.

Application filed December 21, 1910. Serial No. 598,526.

To all whom it may concern? Be it known that I, THoMAsMANEY, a citizen of the United States, residing at Louisville, in the county of J eflerson and State of Kentucky, have invented certain new and useful Improvements in Adjustable Tie-Plates, of which the following is'a specification. Y p

. My invention relates to an improvement in tie plates and rail fastenings to be use in connection therewith.

This tie plate is intended for use more particularly along the general line of unbroken track for the purpose of protecting theties and of restoring the proper distance between the rails without the necessity of removing the tie plate from the "tie. It varies from the ordinary type of tie plate now in use, in that it permits of the adjustment of-the rail upon the tie plate, and thereby avoids the necessity of shifting or moving the tie plate upon the tie for ad usting the rails laterally.

The great objection to the ordinary tie plate is that the tie becomes weakened from driving the spikes into the tie, and thereby prevents the tie plate from being firmly held upon the tie. It is not generally necessary to move a rail to any great distance in a lateral direction; therefore the shifting of the ordinary tie plate would require only a slight movement longitudinally of the tie,

- and therefore the spikes to be driven through the tie plate very close to the holes previously formed by the spikes before the adjustment is made. This objection is overcome by my invention, as my tie plates are arranged so that wedges can be received between the base flange of the rail and the ends of-the tie plate, and in this way, one wedge can be loosened and the other driven on to the tie plate, thereby forcing the rail laterally in the'direction desired.

* When a locomotive or train is standing upon the rails, the rails .are slightly. depressed or deflected from a straight line of surface immediately below the bearing of each wheel, due to the flexibility of the rail, and to the more or less elastic nature of the ground on which the track is laid. This deflection of the rail under the load results in the unweighted parts of the rail, or the parts between the wheels, takipgb a reflex or slightly elevated position." 1 en the wheels the wave motion of the rails.

are set in motion, each point in the length of the rails assumes alternately the depressed and elevated position, or in other words, an undulating or wave motion takes place under moving trains, which is commonly known as This is more or less pronounced, owing to the Weight of rolling load, solidity of'foundation. and stiflness of the rail. The range of this vertical movement is slight, but acts with irresistible force. The result is that the spikes which fasten'the rails to the ties are withdrawn from the ties to the extent of this movement. Therefore if a tie plate is not used, the tie will become worn from the constant vibration of the rail, and it is to overcome this difliculty that tie plates are used. Even when tie plates are used, if the tie plates and rails are fastened directly to the tie by the same fastening means, the fastening means will be raised by the constant wave motion of the rails and the tie plates will cause the ties to become worn by the cutting of the ties by the tie plates. The whole office of a tie plate is to protect the tie from mechanical wear, and to hold the rails securely in their proper relation to each other. The tie plate when inserted and fastened securely to the tie receives the impact and grinding action of the rail, due to the wave motion of the rail, butif the rail is not independently Patented July 8, 1913. p

connected so that the tie plate will be prevented from moving, the tie will be subjected to wear by the tie plate cutting into the tie.

It is therefore my object to provide a tie plate which, when fastened to the tie, will be held firmly upon the tie, and not distain novel features of construction and combinations of parts which will be hereinafter more fully described and pointed out in the claims I 3 In the accompanying drawings -F1gure 1 is a top plan viewshowlng the invention applied to a tie, Fig. 2 is an end view of the tie plate; Fig. 3 is a top plan view of the tie plate with the rail removed; Fig. 4 is a perspective view of the clip, and Fig. 5 is a perspective view of the locking block or lock.

. A, represents the tie plate which is of rolled steel preferably, and provided with shoulders 1, l. Ribs 2, 2, are provided on the under side of the plate which areadapted to be sunk into the tie. The plate is preferablyrolled in long bars, and sheared diagonally instead of at right angles, giving it the proper angle for the wedges 3, 3, which are used in connection with the tie plate for locking the rail B upon the plate, one wedge extending in one direction and the other wedge extending in the opposite direction, so that the rail will be firmly heldand permitting the rail to be adjusted laterally with respect to the tie plate. The

wedges engage the edges of the base flange The screw-bolts'pass through the shoulders of the rail, and one edge of each shoulder 1. Each wedge is provided with notches or indentations 4, of about one-fourth Q) inch in depth. Holes are provided through the shoulders of the tie plate through which screw-bolts 5, 5,- extend. A groove 6 is formed on each shoulder and extends lengthwise of the shoulder. Received in the grooves are locking blocks'or locks 7, which are provided with openings 8 through which the screw-bolts 5 pass, whereby the locking blocks will be firmly held upon the tie plate when the bolts 5 are driven into the ties. Lugs 9 are formed on the blocks 7 and are received in the indentations or notches 4 of the wedges 3 for holding the wedges from movement, and thereby. preventing the wedges from moving, longitudinally after having been fastened in position by the lugs. Steel clips 10 are provided with openings 11 through which screw-bolts 12 extend.

l of the tie plate and cause the flexible steel clips to be held firmly upon the shoulders of the tie plate, and .u on the base flange of the rail, one edge 0 each clip being received in the groove 6 of the shoulders, and the other edge being received upon the base flange of the rail. The bolts 5 and 12 pass loosely through the tie plate. Therefore any upward lift of the rail is imparted to the tie and not to the plate, for the reason that the flexible clips 10 are so arranged that the upward pull of the rail with the' screw spikes 12 as fulcrums forces the plate to a closer adherence to the tie, instead of raising the tie plate upon the upward movement or lift of the rail, due to the wave motion imparted to the rail by a passing train.

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