To all whom it mail concern:

Be it known that I, JOHN R. MGCREADY, a citizen of the United States, residing at Duncansville, in the county of Blair, State of Pennsylvania, have invented certain new and useful Improvements in Railway-Ties; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as'will enable others skilled in the art to which it appertains to make and use the same.

This invention is an improvement in railway ties and has for one of its objects the provision of a tie principally made of metal and having yieldable cushioning means for the rail which means'may be readily removed and replaced when worn out without removing the rail.

Another object is the provision of a railway tie of this. character which is simple in construction, easy to manufacture and effective in carrying out the purpose for which it is designed.

The inventive idea involved is capable of receiving a variety of mechanical expressions, some of which, for the purpose of illustrating the present invention, are shown in the accompanying drawing, wherein Figure 1 is a side elevation of one form of a railway tie constructed in accordance with the invention.

Fig. 2'is a top plan view thereof.

Fig. 3 is a longitudinal section.

Fig. 4 is a transverse section on theline 4:4 of Fig. 2.

Fig. 5 is a perspective view of another form of a tie.

Fig. 6 is longitudinal sectional view thereof.

Referringto the drawing and more particularly to 1 to 4 inclusive, the numoral 10 indicates the base of a tie which extends transversely of the rails and is provided upon its inner end with the lugs 11 which are adapted to be secured to similar lugs formed upon the base of the opposite tie. From this construction. it will be apparent that any one of the ties may be detached from the one to which it is secured in order to replace the same, when necessary.

The base 10 of each tie is preferably of rectangular form and has formed upon each longitudinal edge adjacent the outer end thereof an enlargement 12 including an in clined portion 13 having the triangular opening 14: beneath the same. The top 15 of Specification of Letters Patent.

each enlargement 12 is provided with a chamber 16 having an angular shoulder 17 intermediate the top: and bottom thereof. Gom-municcating with the chamber 16 on the outer side of the tie is an opening 18 normally closed by means of a door 19, said open ig being adapted to receive a relatively yiele :ble block 20, formed of any suitable material, such as wood, whicln-when in position, is seated in the bottom of the chamber 16 and is of a greater thickness than the distance between the bottom of said chamber and the plane ofthe shoulder 17 so as to compensate for wear upon the upper surface of said block. Seated in the chamber 16 and upon the top of said block 20 is a metallic rail supporting plate 21 having the rail 22 secured thereto in any preferred manner and also having its uppermost portion extending above the top of the enlargement 12. Through continued use it will be apparent that the upper surface of the block 20 will be gradually worn away and the plate 21 will .recede into the chamber 16 until the bottom surface thereof contacts the shoulder 17, thus limiting the downward movement of said plate and at this time it is desirable to replace the block 20. This operation may be readily and quickly performed by jacking the rail and removing the door or closure 19 and then extracting the old block 20 from the chamber 17 and through the opening 18, after which a new block may be inserted and the closure 19 again replaced.

Referring now to Figs. 5 and 6, it will be seen that the tie in this instance comprises a base 23 having the lugs 24 at its innor end adapted to be secured to similar lugs upon the base of an adjacent tie and having formed upon its outer transverse edge the enlargement 25 including the inclined portion 26. The top of the enlargement is provided with a chamber 27 having an angular shoulder 28 therein, said chamber communieating with an opening 29 which is normally closed by a door 30, supported upon the outer end of the enlargement 25. Heavy coil springs 31 are seated at the bottom of the chamber 27 and their upper ends normally extend above the shoulder 28 and engage the bottom surface of a rail supporting plate 32 and yieldably support the same in position in the chamber 27, the downward. movement of said plate being limited by the shoulder 28. It will also be apparent from this description, that when necessary the coil springs 31 may be removed and replaced through the opening-29. I

What is claimed is a 1. A railway tie comprising a base havin an enlargement formed thereon provide with a chamber in the top there-of, an angular shoulder in said chamber, a yieldable element seated in said chamber and having its upper surface extending above said shoulder, and a rail. supporting plate mounted upon the top of said yieldable element.

' 2. A railway tie comprising a base having an enlargement formed thereon provided with a chamber'in the top thereof and an opening communicating with said chamber andwith: one side of said enlargement, a

shoulder in said chamber, a yieldable element insertible through said opening into the bottom o'i": said chamber and having its upper end extending above said shoulder, and a rail supporting plate mounted upon the upper end of said yieldable element.

(lopiesofthis patent may be obtained for 3. A railway tie comprising a base having an enlargement formed thereon provided with a chamber in the top thereof and an opening communicating with said chamber and with one side of said enlargement, a yieldable element insertible through said opening into the bottom of said chamber, and arail supporting plate mounted upon said yieldable element.

4. A railway tie comprising a base having an enlargement extending from each longitudinal edge thereof, each enlargement having a chamber, a yieldable element mounted in the bottom of said chamber, and a rail supporting plate supported by said yieldable element."

In testimony whereof, I affix my signature, in the presence of two witnesses.
