METALLIC RAILWAY-TIE.

I Application filed January 6, 19(14- i To aZZ it may concern:

: This invention is an improvement upon the theTaylor patent, No. 525,927.- Such ties havl Serial 1%. 137,899. on model.)

The invention consists in he use, with two chairs having rail-holding claws on their up per surfaces and having transverse slots for the passage of the tie-bar, of a tie-bar made of two parts, each part having upon its upper 55 edge a claw for engaging with the outer edge f of the rail-foot. and in providing means for adjustably securing such parts of the tie bar together, so to slightly increase or decrease ing specifically the construction shown in Figure 1 of that patent and known commercially as 5 5 Chester ties have been put to practical use and with great success when they have been especially suited to the exact conditions of use. They have, however, been criticized by practical railroadcngineers because of their indi- 29 vidual unaclaptabilityQ For example, when they are built especially to fit rails of a definite size, as sixty-five-pound rails, and are i used on straight stretches they are entirely satisfactory; but if it is desired to use heavier 5 rails with the same ties it is only possible to do this by changing the tie-bars and using tie-" bars whose rail-holding claws are separated a slightly-greater distance. This is of course practically objectionable, because it involves a considerable loss whenever the size of the rails is changed. Then again it is customary to slightly spread the rails on curves, the spread being greater or less, depending upon the radius of curvature. These Chester ties are not adaptable to such slight modifications of gage; Tie-bars especially constructed for such slight modifications may of course be provided but to use them it requires that the construct-ion engineer shall carry with him bars of various si zes..as regards the distance between the rail-holding claws. for use under all the varying conditions which arise, in the laying of tracks. This is of course very objectionablefor reasons wholly apart from the 45 increased cost of. making-these various-sized tie-bars. The object of this invention is to render steel ties of the type referred to'universally adaptable to rails of different sizes and to va- 5Q rious slight changes in gage.

claws There is also through the top and 1 and the opposite rail-foot under the claw I) its effective l'ength-. that is to say, the distance 66 type of steel railway-ties which are shown in between the rail-holding claws thereon.

This invention also consists in the more spe'citic constrnction and combinations of parts hereinafterdescribed, and definitely set forth 6 I 5 In the drawings, Fig. 1 is an elevation of Fig. 2 is a'plan view thereof, and Fig. 3 is a perspective view of one of the fish-plates used in connecting the two portions of the tie-bar. 7

Referring to the parts by letters, A A represent the two chairs, which have flat tops (0 and diverging side flanges a, and each chair is alsoprovided with upturning rail-holding 75 the upper partof both 'side hanger; of each chair a slot to which .the tie-bar B is fitted.

A rail C rests upon the flat top surface of each chair with one of the rail-feet under the claws O on the top edge of the tie-bar. To this extent the construction shown is, not new. 4, j

' The tie-bar B in the construction shown is of inve'rted-T shape, having the vertical web 6' and the two horizontal flanges 11*, which ex- 5 tend in opposite directions from the lower edge of the web. This particiilarshape is not, however, essential to the generic invention.- This tie-bar is made of two bars 6,

which meet about midway between the two 9 chairs, and these two bars are connected in. any desired relationship with each other by the fish-plates D and bolts E. It is necessary. however, that this connection. between the two parts of the tie-bar shall be absolutely rigid. Therefore the engaging faces of the fish-plates and bar-sections are, transversely serrated. Specifically the outer faces of the vertical web of the tie-bar and the upper faces a l (it the two flanges thereof are transversely serrated. The fish-plates have outwardly-extending flanges (Z on theirlower edges, which restupon flanges of the tie-bar, and the inner faces of the vertical parts of the fish-plates 5 and the lower faces of the flanges d are cor- 'respondingly serrated and engage with the serrated faces of the ticker; The bolt-holes through the fish-plates are in the form of horizontal slots, which permit the adjustment IQ of the two parts of the tie-bar. Y

By readjusting the relation of the tie-bar sections the space between the claws on the tie-bar and the claws on the chairs may be varied so as to be able to grasp rail-feet of 5' different widths, and the relative position of one or both of the chairs may he also changed. Wherefore it is clear that the described ties vare universally adaptable to difierent-sized rails and to variations in grade within small 20 limits.

Having described my invention, 1 clairn 1. A metallic tie composed of two chairs, having transverse slots through them, and having rail-holding claws on theirupper faces, 5 corhbined with a tie-bar composed of two sections which are fitted respectively to the slots in the chairs, and have on the parts of the barsections which project above said chairs, railholding claws, andmeans whereby to rigidly 3 connect the two sections of said tie-bar, so as to Varythe distance between the rail-holding claws thereon.-

2. A metallic tie compesedof two chairs ;which are transversc ly slotted and have holding claws on t eir top faces, a tieconiposed of two relatively adjustable sect which are respectively fitted to the slot said chairs, and have rail-holding claw:

- their upper edge, fish plates and bolts for necting said tie-bar sections. the enga; surfaces of said fisl1-pia tee and tie har sect being transversely serrated.

3. A metallic tie consisting of two ch having flat tops and ail-holding claws ext ing upward from tops and an inveru slot through the top of the chair and thr both side flanges thereof, with an inverte shaped tie-bar made of two sections whicl respectively fitted to thslots in the ch and are provided with a rail-holding formed inthe upward-projecting \yeb, sections being transversely serrated, at l inner ends, .on the outer faces of the ver web, and on the upper horizontal faces 0 flanges, and angle-iron fish-plates whicli correspondingly serrated on their inner ticai faces and lower horizontal faces, f0 gagement with theserrations on the tie sections, and bolts passing through the plates and tie-bar sections.
