specification of Letters Patent. Patented Dec. 10, 1912.

Application inea Aprile, 1912. serial No. 688,064,

This tie 1 has a top flange Q being prefas shown, the ballast referred to. and a base flange 3, the latter erably arched on its underside to form a housing within which will pack.

4 is insulating material on and nnderlapping the top flanges 2, and'.5 is ,a chair resting on said insulating material. is slightly wider than the'top flange 2 To all whom it may concern.'

Be it known that I, VILLIAM H. MORGAN, a citizen of the United States, residing at in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Railroad-Track Construction; and I do hereby declare the following to be a. full, clear, and exact description of the invention, such as will'y enable others skilled in the art to which' it appertains to make and use theV same. My invention relates to an improvement in railroad track construction, of' the type disclosed in application Serial Number 639,446 filed by lV. V. Hartzell and myself July-18th, 1911. In the construction disclosed in the said application, the spring clamps or clips bear directly against, and are in contact with the base flange of the rail. In the winter, it freqnently'happens that the portions of the road bed exposed to the sun will ,thaw ont, while the portion thereof shaded by trees and other objects will remain frozen. Vith the road bed in such condition, the track over the frozenpart of the road bed will be comparatively rigitl and unyielding, while the portions thereof exposed to the sun will give or yield thus permitting the ties to sink under the weightof a train, and be practicall without support except for the nails, a ter the train has passed. On some roads it is the practice to insert shims between the ties and the rail, over the yielding portions of the track, so as to compensate for the depres` sionof the tie, and form a support for the rail.

In vthe application above referred to the construction is such that the introduction of shims between the tics and rails is prevented by the spring clamps or clips which bind the rails solidly to the ties, and the object of the invention is to so construct the spring clamps and other` parts, that space will be left .for the introduction of shims or wedges whereby the rails may be supported in alinement on ties that have been depressed.

The accompanying drawing is a view in. cross section of a track embodying my invention.

lVhile I do notlimit the use of my invention to any particular shape or construction of metal tie, I have shown it applied to :1 tie having a member extending lengthwise the rail, as disclosed in the application above the depending flanges 6, which overhang lthe side edges of the tie, and with upwadly projecting flanges 7, against which thi/side edges of the base flanges 8 of the` ail 9 abut, the top flanges 7 of the chair,'pfojeet ing slightly above the base flange of l,the rail as shown.

8a are armor plates ribbed asvshown, and resting against the insulating material at the'underside of the top. flange of the tie, and held against the depending flanges 6 of the chair. These armor plates 8, are held in place by the spring clamps'9a, which latter are shaped as shown, and are made preferablyof vanadium steel, or other hard, tough' land finely grained steel or iron alloy, heat/treated if necessary, and of a size sufficient to withstand the strains and shocks to' which they arel subjected. These clamps extend up and around the side edges of thechair 5, and rest on the top of the latter with their upper ends above, but not in contact the rails loose-ly seated on the chairs, but as the resultant of falls within the base of the rail, the only pressure to which a rail is\snbjected, other than downward, is an outward one whish is hence there is, theoretically, no tendency for the rails to tip, but as the ends of the clips overlap the base flange of the rails, and are only removed therefrom a limited distance suflicient to permit of the introduction of shims, it will be seen that tipping to anything like a dangerous extent would be absolutely prevented by the ends of the clips..

It is a well known fact that where wooden ties and spikes are used, after the first train passes over it, the spikes are drawn from the wood leaving a space between the head and the rail; also where the rail is supported at intervals as with cross ties, the rails deflect between the spaces and cause a wave action. 71th my construction the rail is outward displacement by with the base flange of the rail. Thisleaves.

the wheel pressure always- This chair/ 0f the tie and 1s provided at its side edges with .95 taken care of by th'e side flanges of the chair,

I gravity such a.

.my construction is such as to gages a Aan upwardly projecting flange of the chair,

free to move tothe worm action which is not the case between the wooden ties and spikes. The track will move .vertically up 5 and down without'disturbing the ties, and

take care et all side shear.

Engineers endeavor to keep the center of 5 of-locomoftivesland cars loaded'at i height that the downward thrust is within the base of the rail so there is no tendency to turn the rail over. l guard against this side shear by the chair as used l in my construction. By this arrangement it will be seen that if the road bed be soft in spots, it can be supported by the introduction ofshims or wedges which will c0111-, pensate4 for part, if not all, of the movement of. the tie.

Having fully described my invention what I' claim as new and desire to secure by Letj ters-Patent, is v 1. The'eombination of a rail, a tie, a chair located thereon and provided with upwardly projecting anges, and a spring clip or clamp having .two jaws one of which venlixed support on the underside of the Ptop fiange of the tie and the other rests on an upwardly projecting flange ofthe chair with its free end projecting over said latter flangefand over but not in contact with a part resting on said chain( 2. The combination of a' rail, a tie, a chair located. thereon and provided with .upwardly projecting flanges and a spring clip orclamp having two jaws ,one of which engages a fixed stop at thevunderside of the top fiange of the tie and the other rests on with its free end projecting over said latter flange and over but not in contact with the base iange of the rail. A

3. The combination of a rail, a tie, a chair located thereon andv provided*` at its sides with upwardly projecting flanges and two spring clips or clamps each having two jaws, one of which engages a fixed support on the underside of the top flange of the tie and the other rests on an upwardly projecting flange of the chair, the .said clips being located on opposite sides of said chair with their ree ends projecting -over said latter anges' and over but not in contact with, the member resting on said chair.

4. The combination of a rail, a tie, a chair located on the tieand having depending flanges overhanging the side edges of the top flange of the tie and upwardly proj ecting flanges forming side supports tor` the rail, and two spring clips or clamps each yhaving two jaws one of which engages a v,fixed support on the underside of the top flange of the tie and the other rests on an upwardly projecting iiange ot the chair, the' said clips or clamps being located on opposite sides of the chairy with their ree ends projecting over said latter flanges and over but `not`in contact with the base ange of therail resting on said chair.

In testimony whereof, I have signed thisl specification in the presence of two subscribing w1tnesses.
